A 67-year-old man developed dysuria and position-dependent obstructive voiding symptoms after undergoing holmium laser ablation of the prostate (HOLAP) for benign prostatic hypertrophy. A large fungal (candidal) ball adherent to the bladder wall was removed by loop excision, but the bezoar recurred in 2 weeks despite systemic fluconazole and intravesical amphotericin B. A second attempt at endoscopic removal with ultrasonic lithotripsy, endoscopic graspers, and fulguration was also unsuccessful. The patient underwent open partial cystectomy to remove his invasive fungal bezoar. Convalescence was unremarkable. Urinalysis, culture, and follow-up cystoscopy after partial cystectomy demonstrated successful definitive treatment of the fungal ball. Copyright © 2012 Elsevier Inc. All rights reserved.

Radical cystectomy, which is performed to treat muscle-invasive bladder tumors, is among the most difficult urological surgical procedures and puts patients at risk of intraoperative blood loss and transfusion. Fluid management via stroke volume variation (SVV) is associated with reduced intraoperative blood loss. Therefore, we evaluated the efficacy and safety of SVV-guided fluid therapy for reducing blood loss and transfusion requirements in patients undergoing radical cystectomy.This study included 48 patients who underwent radical cystectomy, and these patients were randomly allocated to the control group and maintained at <10% SVV (n = 24) or allocated to the trial group and maintained at 10% to 20% SVV (n = 24). The primary endpoints were comparisons of the amounts of intraoperative blood loss and transfused red blood cells (RBCs) between the control and trial groups during radical cystectomy. Intraoperative blood loss was evaluated through the estimated blood loss and estimated red cell mass loss. The secondary endpoints were comparisons of the postoperative outcomes between groups.A total of 46 patients were included in the final analysis: 23 patients in the control group and 23 patients in the trial group. The SVV values in the trial group were significantly higher than in the control group. Estimated blood loss, estimated red cell mass loss, and RBC transfusion requirements in the trial group were significantly lower than in the control group (734.3 ± 321.5 mL vs 1096.5 ± 623.9 mL, P = 0.019; 274.1 ± 207.8 mL vs 553.1 ± 298.7 mL, P <0.001; 0.5 ± 0.8 units vs 1.9 ± 2.2 units, P = 0.005). There were no significant differences in postoperative outcomes between the two groups.SVV-guided fluid therapy (SVV maintained at 10%-20%) can reduce blood loss and transfusion requirements in patients undergoing radical cystectomy without resulting in adverse outcomes. These findings provide useful information for optimal fluid management during radical cystectomy.

To evaluate single-port assisted extracorporeal cystectomy for treatment of large ovarian cysts and to compare its surgical outcomes, complications, and cystic content spillage rates with those of conventional laparoscopy and laparotomy. Retrospective study (Canadian Task Force classification II-2). University teaching hospital. Twenty-five patients who underwent single-port assisted extracorporeal cystectomy (group 1), 33 patients who underwent conventional laparoscopy (group 2), and 25 patients who underwent laparotomy (group 3). Surgical outcomes, complications, and spillage rates in group 1 were compared with those in groups 2 and 3. Patients characteristics and tumor histologic findings were similar in the 3 groups. The mean (SD) largest diameter of ovarian cysts was 11.4 (4.2) cm in group 1, 9.7 (2.3) cm in group 2, and 12.0 (3.4) cm in group 3. Operative time in groups 1 and 2 was similar at 69.3 (26.3) minutes vs 73.1 (36.3) minutes (p = .66); however, operative time in group 1 was shorter than in group 3, at 69.3 (26.3) minutes vs 87.5 (26.6) minutes (p =.02). Blood loss in group 1 was significantly lower than in groups 2 and 3, at 16.0 (19.4) mL vs 36.1 (20.7) mL (p < .001) and 16.0 (19.4) mL vs 42.2 (39.7) mL (p = .005). The spillage rate in group 1 was profoundly lower than in group 2, at 8.0% vs 69.7% (p < .001). Single-port assisted extracorporeal cystectomy offers an alternative to conventional laparoscopy and laparotomy for management of large ovarian cysts, with comparable surgical outcomes. Furthermore, cyst content spillage rate in single-port assisted extracorporeal cystectomy was remarkably lower than that in conventional laparoscopy. Copyright © 2015. Published by Elsevier Inc.

Urinary tract infections (UTI) and sepsis contribute significantly to the morbidity associated with cystectomy and urinary diversion in the first 30 days. We hypothesized that continuous antibiotic prophylaxis decreased UTIs in the first 30 days following radical cystectomy. Patients with urothelial carcinoma of the bladder who underwent a radical cystectomy with urinary diversion for bladder cancer at Oregon Health and Science University from January 2014 to May 2015 were included in the study. The ureteral stents were kept for 3 weeks in both groups. In October 2014, we enacted a Department Quality Initiative to reduce UTIs. Following the initiative, all radical cystectomy patients were discharged home on antibiotic prophylaxis following a postoperative urine culture obtained during hospitalization. To evaluate the effectiveness of the initiative, the last 42 patients before the initiative were compared to the first 42 patients after the initiative with regard to the rate of UTI in the first 30 days following surgery. We used a combination of comprehensive chart review and the American College of Surgeons' National Surgical Quality Improvement Program (NSQIP) to determine UTI and readmission for urosepsis in the first 30 days following surgery. This ensured accurate capture of all patients developing a UTI. A total of 12% in the prophylactic antibiotic group had a documented UTI, whereas 36% in the no antibiotic group had a urinary tract infection (P<0.004). A total of 1 (2%) patient in the antibiotic group was readmitted for urosepsis whereas 7 (17%) patients in the no antibiotic group were admitted for urosepsis (P = 0.02). There was no association noted between urine culture at discharge and the development of UTI in the 30-day postdischarge period (P = 0.75). The median time to UTI was 19 days and the most common organism was Enterococcus (32%). Thirty-percent of patients not receiving prophylaxis developed a UTI 1 day after ureteral stent removal. No patients had a UTI following stent removal in the prophylaxis group. No adverse antibiotic related events were noted. Prophylactic antibiotics in the 30 days following radical cystectomy is associated with a significant decrease in urinary tract infections and readmission from urosepsis after surgery.

To determine the incidence of spreading bladder transitional cell carcinoma and primary adenocarcinoma to the prostate in patients with bladder cancer undergoing radical cystectomy. From 1995 to 2016, 283 men underwent radical cystectomy with removal of the bladder, perivesical tissue, prostate, seminal vesicles and pelvic lymph nodes. Prostate sparing cystectomy was performed in 45 (13.7%) patients. The whole prostate and the apex of the prostate were preserved in 21 (6.4%) and 24 (7.3%) patients, respectively. The spread of transitional cell cancer of the bladder to the prostate occurred in 50 (15.2%) patients. Twelve (3.6%) patients were found to have primary prostate adenocarcinoma. Clinically significant prostate cancer was diagnosed in 4 (33.3%) patients. We believe that the high oncological risk of prostate sparing cystectomy, despite some functional advantages, dictates the need for complete removal of the prostate in the surgical treatment of bladder cancer.

Radical cystectomy is the standard therapy for invasive bladder cancer, with best oncological results compared to any other therapeutic alternative. Even if laparoscopic radical cystectomy (LRC) is a well established surgical procedure, performing the urinary diversion completely intracorporeal, is still a challenge due to technical difficulties and associated complications. The aim of our study is to present the first series of LRC with ureterosigmoidostomy. Since May 2004 were performed 7 LRC (5 males and 2 females) (Gr. A). All cases were T2N0 clinical stage. These patients were compared with a retrospective group of 50 patients who underwent open procedure (Gr. B) in term of: operative time, blood loss, analgesic requirements, and hospital stay. LRC has a longer operative time but with statistically significant lower blood loss, less analgesia, and shorter hospital stay. The resection margins of the surgical specimens were tumor free at pathologic examination. Long-term follow-up is pending. On short-term, the results of laparoscopic radical cystectomy are encouraging. When significant experience in laparoscopic surgery is lacking, surgeons should exercise caution with completely intracorporeal urinary diversion.

To investigate the incidence and microbiology of urinary tract infection (UTI) within 90 days following radical cystectomy (RC) and urinary diversion. We reviewed 1133 patients who underwent RC for bladder cancer at our institution between 2003 and 2013; 815 patients (72%) underwent orthotopic diversion, 274 (24%) ileal conduit, and 44 (4%) continent cutaneous diversion. 90-day postoperative UTI incidence, culture results, antibiotic sensitivity/resistance and treatment were recorded through retrospective review. Fisher's exact test, Kruskal-Wallis test, and multivariable analysis were performed. A total of 151 urinary tract infections were recorded in 123 patients (11%) during the first 90 days postoperatively. 21/123 (17%) had multiple infections and 25 (20%) had urosepsis in this time span. Gram-negative rods were the most common etiology (54% of positive cultures). 52% of UTI episodes led to readmission. There was no significant difference in UTI rate, etiologic microbiology (Gram-negative rods, Gram-positive cocci, fungi), or antibiotic sensitivity and resistance patterns between diversion groups. Resistance to quinolones was evident in 87.5% of Gram-positive and 35% of Gram-negative bacteria. In multivariable analysis, Charlson Comorbidity Index > 2 was associated with higher 90-day UTI rate (OR = 1.8, 95% CI 1.1-2.9, p = 0.05) and Candida UTI (OR 5.6, 95% CI 1.6-26.5, p = 0.04). UTI is a common complication and cause of readmission following radical cystectomy and urinary diversion. These infections are commonly caused by Gram-negative rods. High comorbidity index is an independent risk factor for postoperative UTI, but diversion type is not.

To assess morbidity and functional consequences of laparoscopic cystectomy with ileal conduit urinary diversion: in neurologic patients. We reviewed the records of forty-two patients (ten men and thirty-two women) who underwent surgery between August 2007 and October 2013. The median age of the patient was 54 years old (range between 21-79 years). A laparoscopic cystectomy was performed followed by a short laparotomy to perform the ileal conduit urinary diversion. Records were reviewed to retrieve the indications and describe the postoperative and functional course. Patients and GPs were interviewed during phone calls to appreciate the quality of life by the PGII scale in order to assess the functional outcome. The operation was performed on 42 patients, of whom 18 had multiple sclerosis, nine a post-traumatic neurogenic bladder. Among the total population, 10 patients (23.81%) required a transfusion of at least one packed red blood cells (1-7). The overall rate of early complications was 35.71%. Belated complications were seen in 52.38% of the population. The median duration of hospital stay was 16 days (range between 9-70 days). The median follow up was 34 months (range between 1-76 months). For patients, the PGII scale rating had a median value of 6 (2-7). All referring physicians described a better functional status. The laparoscopic cystectomy can make postoperative course smoother for the neurological patients. However, the surgeon must weigh individually the benefit of performing the operation.

Robot-assisted radical cystectomy (RARC) has evolved as a minimally invasive alternative to open radical cystectomy for patients with invasive bladder cancer. We sought to define the learning curve for RARC by evaluating results from a multicenter, contemporary, consecutive series of patients who underwent this procedure. Utilizing the International Robotic Cystectomy Consortium database, a prospectively maintained and institutional review board-approved database, we identified 496 patients who underwent RARC by 21 surgeons at 14 institutions from 2003 to 2009. Cut-off points for operative time, lymph node yield (LNY), estimated blood loss (EBL), and margin positivity were identified. Using specifically designed statistical mixed models, we were able to inversely predict the number of patients required for an institution to reach the predetermined cut-off points. Mean operative time was 386 min, mean EBL was 408 ml, and mean LNY was 18. Overall, 34 of 482 patients (7%) had a positive surgical margin (PSM). Using statistical models, it was estimated that 21 patients were required for operative time to reach 6.5h and 8, 20, and 30 patients were required to reach an LNY of 12, 16, and 20, respectively. For all patients, PSM rates of <5% were achieved after 30 patients. For patients with pathologic stage higher than T2, PSM rates of <15% were achieved after 24 patients. RARC is a challenging procedure but is a technique that is reproducible throughout multiple centers. This report helps to define the learning curve for RARC and demonstrates an acceptable level of proficiency by the 30th case for proxy measures of RARC quality.

One series of robot-assisted radical cystectomy with pelvic lymph node dissection has been reported. We report our operative technique and initial experience. Twenty consecutive patients underwent robot-assisted radical cystectomy, pelvic lymph node dissection, and open urinary diversion for operable bladder cancer from October 2005 to June 2006. Data were collected prospectively on patient demographics, intraoperative parameters, pathologic staging, and postoperative outcomes. The mean patient age was 70 years (range 56 to 90). The mean body mass index was 26 kg/m2 (range 17.3 to 36). Fourteen patients had undergone previous abdominal surgery. The mean operative time was 197 minutes for robot-assisted radical cystectomy, 44 minutes for pelvic lymph node dissection, and 133 minutes for urinary diversion. The mean blood loss was 555 mL. One case was converted to an open procedure because of the patient's inability to tolerate the Trendelenburg position. The mean hospital stay was 10 days. Two patients had major complications. One patient had positive vaginal margins and 9 of 26 nodes were positive. Four patients had incidental prostate cancer. The mean time to the return to nonstrenuous activity was 4 weeks and to strenuous activity was 10 weeks. Robot-assisted radical cystectomy and pelvic lymph node dissection can be performed safely in patients who are considered candidates for open cystectomy. Long-term oncologic control data and functional outcomes are needed to assess the true benefits of robot-assisted radical cystectomy.

Radical cystectomy represents the standard of care for muscle invasive bladder cancer (MIBC). Due to its novelty the use of robotic radical cystectomy (RARC) is still under debate. We examined intraoperative and postoperative morbidity and mortality as well as impact on length of stay (LOS) and total hospital charges (THCGs) of RARC compared to open radical cystectomy (ORC). Within National Inpatient Sample (NIS) (2008-2013), we identified patients with non-metastatic bladder cancer treated with either ORC or RARC. We relied on inverse probability of treatment weighting (IPTW) to reduce the effect of inherent differences between ORC vs. RARC. Multivariable logistic regression (MLR) and multivariable Poisson regression models (MPR) were used. Of all 10 027 patients, 12.6% underwent RARC. Between 2008 and 2013, RARC rates increased from 0.8 to 20.4% [Estimated annual percentage change (EAPC): +26.5%, CI: +11.1 to +48.3; p=0.035] and RARC THCGs decreased from 45 981 to 31 749 United States Dollars (EAPC: -6.8%, CI: -9.6 to -3.9; p=0.01). In MLR models RARC resulted in lower rates of overall complications (OR: 0.6; p <0.001) and transfusions (OR: 0.44; p <0.001). In MPR models, RARC was associated with shorter LOS [relative risk(RR)0.91 ; p <0.001]. Finally, higher THCGs (OR: 1.09; p <0.001) were recorded for RARC. Data are retrospective and no tumor characteristics were available. RARC is related to lower rates of overall complications and transfusions rates. In consequence, RARC is a safe and feasible technique in select muscle invasive bladder cancer patients. Moreover, RARC is associated with shorter LOS albeit higher THCGs.  .

Purpose Multidisciplinary management improves complex treatment decision making in cancer care, but its impact for bladder cancer (BC) has not been documented. Although radical cystectomy (RC) currently is viewed as the standard of care for muscle-invasive bladder cancer (MIBC), radiotherapy-based, bladder-sparing trimodal therapy (TMT) that combines transurethral resection of bladder tumor, chemotherapy for radiation sensitization, and external beam radiotherapy has emerged as a valid treatment option. In the absence of randomized studies, this study compared the oncologic outcomes between patients treated with RC or TMT by using a propensity score matched-cohort analysis. Methods Data from patients treated in a multidisciplinary bladder cancer clinic (MDBCC) from 2008 to 2013 were reviewed retrospectively. Those who received TMT for MIBC were identified and matched (for sex, cT and cN stage, Eastern Cooperative Oncology Group status, Charlson comorbidity score, treatment date, age, carcinoma in situ status, and hydronephrosis) with propensity scores to patients who underwent RC. Overall survival and disease-specific survival (DSS) were assessed with Cox proportional hazards modeling and a competing risk analysis, respectively. Results A total of 112 patients with MIBC were included after matching (56 who had been treated with TMT, and 56 who underwent RC). The median age was 68.0 years, and 29.5% had stage cT3/cT4 disease. At a median follow-up of 4.51 years, there were 20 deaths (35.7%) in the RC group (13 as a result of BC) and 22 deaths (39.3%) in the TMT group (13 as a result of BC). The 5-year DSS rate was 73.2% and 76.6% in the RC and TMT groups, respectively ( P = .49). Salvage cystectomy was performed in 6 (10.7%) of 56 patients who received TMT. Conclusion In the setting of a MDBCC, TMT yielded survival outcomes similar to those of matched patients who underwent RC. Appropriately selected patients with MIBC should be offered the opportunity to discuss various treatment options, including organ-sparing TMT.

This study aimed to assess the short-term efficacy of sequential therapy for T2/T3a bladder cancer with intravesical single-port laparoscopic partial cystectomy or open partial cystectomy combined with cisplatin plus gemcitabine (GC) chemotherapy in a prospective randomized controlled study. Thirty patients with bladder cancer who underwent open partial cystectomy (group A) or single-port laparoscopic partial cystectomy (group B) and received standard GC chemotherapy were analyzed. Perioperative functional indicators and tumor recurrence during a 1-year postoperative follow-up were compared between the two groups. The baseline characteristics were comparable between the two groups. The mean operative time, amount of blood loss and duration of hospital stay were 90.3 min, 182.0 ml and 7.3 days, respectively, for group A, and 105.3 min, 49.3 ml and 5.8 days, respectively, for group B. No secondary postoperative bleeding, urine leakage, wound infection or other complications were observed in the two groups. Postoperative scarring was not evident in group B. The overall incidence of surgical complications, tumor recurrence rate and complications during chemotherapy in the postoperative follow-up period of 12 months were similar between the two groups. Single-port laparoscopic partial cystectomy surgery is an idea surgical method for the treatment of invasive bladder cancer, with good surgical effect, minimal invasiveness, rapid recovery and short hospital stay. The data from 1-year postoperative follow-up showed that laparoscopic surgery was superior with regard to perioperative bleeding, postoperative recovery and duration of indwelling urinary catheter use. However, regarding the tumor recurrence rate, long-term comparative details are required to determine the effect of laparoscopic surgery. PMID:26170915

To present our technique and initial experience with patients who underwent robot-assisted intracorporeal creation of ileal conduit and to compare them with patients who underwent extracorporeal ileal diversion after robot-assisted radical cystectomy. Twenty-six patients diagnosed with invasive transitional cell carcinoma of the bladder underwent a robot-assisted radical cystectomy with bilateral extended pelvic lymphadenectomy with ileal conduit diversion. Total intracorporeal ileal conduit creation was performed in the last 13 patients. Operative data and short-term outcomes between the 2 groups were assessed. The novel surgical technique for intracorporeal ileal conduit will be presented. The intracorporeal group (IC) included 2 female and 11 male patients (mean age 71 years). The extracorporeal group (EC) included 4 female and 9 male patients (mean age 66 years). No significant differences were noted between the groups in terms of patient age, BMI, sex, prior surgery, or pathologic stage. Overall operative time and intraoperative complications were similar. No significant differences were noted between the 2 groups in terms of diversion time or estimated blood loss. There were 4 complications recorded in IC patients, including nonspecific colitis, small bowel obstruction requiring exploratory laparotomy with lysis of adhesions, a urine leak that eventually resolved but required a temporary nephrostomy tube, and a fever of unknown origin that resolved without intervention. Robot-assisted intracorporeal ileal conduit can be accomplished safely with acceptable operative times even during early experience. Larger series with favorable results will be required to add this new paradigm to minimally invasive surgery for bladder cancer. Copyright © 2010 Elsevier Inc. All rights reserved.

Stenting Prior to Cystectomy is an Independent Risk Factor for Upper Urinary Tract Recurrence.

Patients with bladder cancer who present with hydronephrosis may require drainage of the affected kidney before receiving further cancer treatment. Drainage can be done by retrograde stenting or percutaneously. However, retrograde stenting carries the risk of tumor cell spillage to the upper urinary tract. The aim of this study was to evaluate whether patients with bladder cancer are at higher risk for upper urinary tract recurrence if retrograde stenting has been performed prior to radical cystectomy. We retrospectively analyzed the records of 1,005 consecutive patients with bladder cancer who underwent radical cystectomy at our department between January 2000 and June 2016. Negative intraoperative ureteral margins were mandatory for study inclusion. Patients received regular followup according to our institutional protocol, including imaging of the upper urinary tract and urine cytology. Preoperative drainage of the upper urinary tract was performed in 114 of the 1,005 patients (11%), including in 53 (46%) by Double-J® stenting and in 61 (54%) by percutaneous nephrostomy. Recurrence developed in the upper urinary tract in 31 patients (3%) at a median of 17 months after cystectomy, including 7 of 53 (13%) in the Double-J group, 0% in the nephrostomy group and 24 of 891 (3%) in the no drainage group. Multivariate regression analysis revealed a higher risk of upper urinary tract recurrence if patients underwent Double-J stenting (HR 4.54, 95% CI 1.43-14.38, p = 0.01) and preoperative intravesical instillations (HR 2.94, 95% CI 1.40-6.16, p = 0.004). Patients who undergo Double-J stenting prior to radical cystectomy are at higher risk for upper urinary tract recurrence. If preoperative upper urinary tract drainage is required, percutaneous drainage might be recommended. Copyright © 2017 American Urological Association Education and Research, Inc.

A 28-year-old woman presented with weight loss and tiredness. Investigations revealed hyperthyroidism. She was commenced on treatment and later became pregnant. Her thyroid levels remained raised, and she later underwent an elective cesarean delivery and ovarian cystectomy. Only a partial cystectomy was achieved, and histopathology examination revealed struma ovarii. An isotope uptake scan ((123)I) including her pelvis revealed low uptake in the thyroid gland and an area of high uptake in her pelvis. The cyst was subsequently removed, and within days, her thyroid hormone levels dropped. This case illustrates the importance of considering uncommon causes of hyperthyroidism.

Radical cystectomy followed by urinary diversion or reconstruction (RC) is a standard treatment for patients with muscle-invasive bladder cancer. In these operations, a high frequency of complications, especially postoperative infection, has been reported. However, there have only been a few studies about postoperative anaerobic bacterial infection. To clarify the significance and role of anaerobic bacteria in postoperative infection, we retrospectively analyzed cases in which postoperative infection by these organisms developed. A total of 126 patients who underwent RC from 2006 to 2010 were included in this study. Various types of postoperative infection occurred in 66 patients. Anaerobic bacterial infections were detected with cultures for urine and blood in one case, for blood in two cases, and for surgical wound pus in four. The frequency of postoperative anaerobic bacterial infection in RC was less than that of colon surgery. However, this study revealed the possible development of a nonnegligible number of postoperative anaerobic bacterial infections. Therefore, we should consider anaerobic bacteria as possible pathogens in postoperative infection after RC.

Although the significance of preoperative nutritional status has been investigated, there is no report regarding the relationship of their postoperative changes on outcomes in patients who underwent radical cystectomy for bladder cancer. Here, we report the clinical impact of the change, from baseline, in nutritional status and volume of abdominal skeletal muscle mass and adipose tissue after radical cystetomy. A retrospective analysis of 89 patients with bladder cancer, who underwent curative radical cystectomy, was conducted to assess the time course of change, from baseline, in body composition and nutritional status at 1, 3, 6, 12, and 24 months, after surgery. Skeletal muscle mass and abdominal adipose tissue mass were quantified by unenhanced computed tomography images. Two different nutritional indices, the Prognostic Nutritional Index and the Controlling Nutritional Status score were calculated from laboratory blood tests. We evaluated the prognostic value of the rate of change in the body composition and nutritional status after radical cystectomy. The cross-sectional area at the level of the third lumbar vertebra of the psoas major muscle and nutritional indices showed a transient deterioration at 1 and 3 months after radical cystectomy, with a return to baseline values from 6 to 24 months. A ≤ -10% loss in the area of the psoas muscle was associated with a shorter overall survival, compared to those with a > -10 change [hazard ratio (HR) 2.2, P = 0.02]. Multivariate analyzes identified sarcopenia status at baseline (HR 2.2, P = 0.03) and a ≤ -10% loss in the psoas muscle (HR 2.4, P = 0.02) were identified as independent prognostic factors for overall survival. A subanalysis of patients without sarcopenia identified a worse survival outcome for patients with a ≤ -10% loss in the psoas muscle (HR 2.6, P = 0.03) and ≤ - 5 change in the Prognostic Nutritional Index (HR 3.6, P = 0.01). Further research is required to establish appropriate rehabilitation protocols and nutritional interventions after radical cystectomy for maintaining skeletal muscle mass and nutrition status which could counteract physical deterioration and improve outcomes.

Purpose: To investigate the associations of ERBB 2 overexpression with chemoradiation therapy (CRT) resistance and cancer-specific survival (CSS) in muscle-invasive bladder cancer (MIBC) patients treated with the CRT-based bladder-sparing protocol. Methods and Materials: From 1997 to 2012, 201 patients with cT2-4aN0M0 bladder cancer were treated with CRT (40 Gy with concurrent cisplatin) following transurethral resection of bladder tumor (TURBT). Basically, patients with tumors that showed good CRT response and were amenable to segmental resection underwent partial cystectomy (PC) with pelvic lymph node dissection for bladder preservation; otherwise, radical cystectomy (RC) was recommended. Included in this study were 119 patients in whom TURBTmore » specimens were available for immunohistochemical analysis of ERBB 2 expression. Following CRT, 30 and 65 patients underwent PC or RC, respectively; the remaining 24 patients did not undergo cystectomy. Tumors were defined as CRT-resistant when patients did not achieve complete response after CRT. Associations of ERBB 2 overexpression with CRT resistance and CSS were evaluated. Results: CRT resistance was observed clinically in 56% (67 of 119 patients) and pathologically (in cystectomy specimens) in 55% (52 of 95 patients). ERBB 2 overexpression was observed in 45 patients (38%). On multivariate analysis, ERBB 2 overexpression was an independent predictor for CRT resistance clinically (odds ratio, 3.6; P=.002) and pathologically (odds ratio, 2.9; P=.031). ERBB 2 overexpression was associated with shorter CSS (5-year CSS rates, 56% vs 87% for the ERBB 2 overexpression group vs the others; P=.001). ERBB 2 overexpression was also an independent risk factor for bladder cancer death at all time points of our bladder-sparing protocol (pre-CRT, post-CRT, and post-cystectomy). Conclusions: ERBB 2 overexpression appears relevant to CRT resistance and unfavorable CSS in MIBC patients treated with the CRT-based bladder-sparing protocol. ERBB 2-targeting treatment may improve the outcomes of such patients.« less

The aim of the study is to investigate the advantages and disadvantages of low-temperature radiofrequency ablation of pharyngolaryngeal cyst.The study population was composed of 84 children diagnosed with pharyngolaryngeal cyst who underwent surgical treatment at the Department of Otolaryngology, Wuhan Children's Hospital, Wuhan, China, between January 1984 and December 2013. All patients were operated using a self-retaining laryngoscope and were divided into 3 groups: traditional cystectomy group (N = 9), dynamic cutting system group (N = 18), and low-temperature radiofrequency ablation group (N = 57). Clinical outcomes were analyzed to assess the efficacy of low-temperature radiofrequency ablation in treatment of pharyngolaryngeal cyst.Compared with traditional cystectomy group or dynamic cutting system group, operation time was shorter, bleeding was less and one-year recurrence rate was much lower in low-temperature radiofrequency ablation group. However, operation time and bleeding was not statistically different between traditional cystectomy and dynamic cutting system group.Low-temperature radiofrequency ablation may be an effective substitute for treating pharyngolaryngeal cyst.

The presence of postoperative bile leak is the major outcome measure for the assessment of operative success in partial cystectomy for hydatid liver disease. However, the optimal operative strategy to reduce the postoperative bile leak rate is yet to be defined. Medical records of patients who underwent partial cystectomy for hydatid liver disease between January 2013 and January 2015 were reviewed in this retrospective analysis. All patients were managed with a specific operative protocol. The primary outcome measure was the rate of persistent postoperative bile leak. The secondary outcome measures were the morbidity and mortality rate, and the length of hospital stay. Twenty-eight patients were included in the study. Only one patient (3.6 %) developed persistent postoperative bile leak. The overall morbidity and mortality rate was 17.8 and 0 %, respectively. The median length of hospital stay was 5 days. Aggressive preventative surgical measures have led to low persistent bile leak rates with low morbidity and mortality.

Aim: To investigate quality of life (QoL) domains with three forms of urinary diversions, including ileal conduit, MAINZ pouch, and orthotopic ileal neobladder after radical cystectomy in men with muscle-invasive bladder cancer. Materials and Methods: In a prospective study, 149 men underwent radical cystectomy and urinary diversion (70 ileal conduit, 16 MAINZ pouch, and 63 orthotopic ileal neobladder). Different domains of QoL, including general and physical conditions, psychological status, social status, sexual life, diversion-related symptoms, and satisfaction with the treatment were assessed using an author constructed questionnaire. Assessment was performed at three months postoperatively. Results: In questions addressing psychological status, social status, and sexual life, patients with continent diversion had a more favorable outcome (P = 0.002, P = 0.01, and P = 0.002, respectively). The rate of erectile dysfunction did not differ significantly between the three groups (P = 0.21). The rate and global satisfaction was higher with the MAINZ pouch (68.7%) and ileal neobladder (76.2%) as compared with the ileal conduit group (52.8%) (P = 0.002). Conclusion: Continent urinary diversion after radical cystectomy provides better results in terms of QoL as compared with ileal conduit diversion. PMID:24049384

We performed a single-institution retrospective analysis of 137 patients with muscle-invasive urothelial carcinoma who underwent neoadjuvant chemotherapy and radical cystectomy to assess the prognostic significance of carcinoma in situ (CIS). The pathologic complete response rates were significantly decreased for patients with CIS identified on transurethral resection of the bladder tumor before treatment. The long-term follow-up data from patients with isolated CIS at cystectomy revealed prolonged progression-free and overall survival. Background Carcinoma in situ (CIS) is a poor prognostic finding in urothelial carcinoma. However, its significance in muscle-invasive urothelial carcinoma (MIUC) treated with neoadjuvant chemotherapy (NAC) is uncertain. We assessed the effect of CIS found in pretreatment transurethral resection of bladder tumor (TURBT) biopsies on the pathologic and clinical outcomes. Materials and Methods Subjects with MIUC treated with NAC before cystectomy were identified. The pathologic complete response (pCR) rates stratified by TURBT CIS status were compared. The secondary analyses included tumor response, progression-free survival (PFS), overall survival (OS), and an exploratory post hoc analysis of patients with pathologic CIS only (pTisN0) at cystectomy. Results A total of 137 patients with MIUC were identified. TURBT CIS was noted in 30.7% of the patients. The absence of TURBT CIS was associated with a significantly increased pCR rate (23.2% vs. 9.5%; odds ratio, 4.08; 95% confidence interval, 1.19–13.98; P = .025). Stage pTisN0 disease was observed in 19.0% of the TURBT CIS patients. TURBT CIS status did not significantly affect the PFS or OS outcomes. Post hoc analysis of the pTisN0 patients revealed prolonged median PFS (104.5 vs. 139.9 months; P = .055) and OS (104.5 vs. 152.3 months; P = .091) outcomes similar to those for the pCR patients. Conclusion The absence of CIS on pretreatment TURBT in patients with MIUC undergoing NAC was associated with increased pCR rates, with no observed differences in PFS or OS. Isolated CIS at cystectomy was frequently observed, with lengthy PFS and OS durations similar to those for pCR patients. Further studies aimed at understanding the biology and clinical effect of CIS in MIUC are warranted. PMID:28040424

The aim of this study was to assess the effect of introducing an enhanced recovery programme (ERP) to an established robot-assisted radical cystectomy (RARC) service. Data were prospectively collected on 221 consecutive patients undergoing totally intracorporeal RARC between December 2003 and May 2014. The ERP was specifically designed to support an evolving RARC service, where increasing proportions of patients requiring radical cystectomy underwent RARC. Patient demographics and outcomes before and after implementation of the ERP were compared. The primary endpoint was length of stay (LOS). Secondary outcomes included age, American Society of Anesthesiologists (ASA) score, preoperative staging, operative time, complications and readmissions. Differences in outcomes between patients before and after implementation of ERP were tested with the Jonckheere-Terpstra trend test and quantile regression with backward selection. Following implementation of the ERP, the demographics of the patients (n = 135) changed, with median age increasing from 66 to 70 years (p < 0.01), higher ASA grade (p < 0.001), higher preoperative stage cancer (pT ≥ 2, p < 0.05) and increased likelihood of undergoing an ileal conduit diversion (p < 0.001). Median LOS before ERP was 9 days [interquartile range (IQR) 8-13 days] and after ERP was 8 days (IQR 6-10 days) (p < 0.001). ASA grade and neoadjuvant chemotherapy also affected LOS (p < 0.05 and p < 0.01, respectively). There was no significant difference in 30 day complication rates, readmission rates or 90 day mortality, with 59% experiencing complications before ERP implementation and 57% after implementation. The majority of complications were low grade. Patient demographics changed as the RARC service evolved from selected patients to a general service. Despite worsening demographics, LOS decreased following ERP implementation. This evidence-based ERP safely standardized perioperative care, resulting in decreased LOS and decreased variability in LOS.

We compared the differential expression of cyclooxygenase-2 in normal bladder tissue, primary bladder transitional cell carcinoma and transitional cell carcinoma metastases to lymph nodes, and determined whether cyclooxygenase-2 expression is associated with molecular alterations commonly found in bladder transitional cell carcinoma and clinical outcomes after radical cystectomy. Immunohistochemical staining for cyclooxygenase-2, survivin (Novus Biologicals, Littleton, Colorado), p21, p27, pRB, p53, MIB-1, Bax, Bcl-2, cyclin D(1) (Dakotrade mark), cyclin E (Oncogene, Cambridge, Massachusetts) and caspase-3 (Cell Signaling, Beverley, Massachusetts) was performed on archival bladder specimens from 9 subjects who underwent cystectomy for benign causes, 21 patients who underwent transurethral resection and 157 consecutive patients after radical cystectomy, and on 41 positive lymph nodes. Cyclooxygenase-2 was expressed in none of the 9 normal bladder specimens (0%), 52% of transurethral resection specimens, 62% of cystectomy specimens and 80% of lymph nodes involved with transitional cell carcinoma. Cyclooxygenase-2 expression was associated with higher pathological stage, lymphovascular invasion and metastases to lymph nodes (p=0.001, 0.045 and 0.002, respectively). Cyclooxygenase-2 expression was associated with altered expression of p53 (p=0.039), pRB (p=0.025), cyclin D1 (p=0.034) and caspase-3 (p=0.014). On univariate analysis cyclooxygenase-2 expression was associated with an increased risk of disease recurrence and bladder cancer specific mortality (p=0.0189 and 0.0472, respectively). However, on multivariate analysis only pathological stage and metastases to lymph nodes were associated with disease recurrence (p<0.001 and <0.001) and survival (p<0.001 and 0.015, respectively). Cyclooxygenase-2 is not expressed in normal bladder urothelium. Cyclooxygenase-2 over expression is associated with pathological and molecular features of biologically aggressive disease, suggesting a role for cyclooxygenase-2 in bladder cancer development and invasion.

We aimed to evaluate the relative prognostic impact of the most common variant histologies on disease-specific survival (DSS) in patients undergoing radical cystectomy. The Surveillance, Epidemiology, and End Result database was used to identify patients who underwent radical cystectomy for bladder cancer from 1990 to 2007. Patients with urothelial cell carcinoma (UCC), squamous cell carcinoma (SCC), adenocarcinoma (AC), sarcoma, small cell carcinoma, signet ring carcinoma, and spindle cell carcinoma were included in the study. Multivariable analysis was performed using Cox proportional hazards model to assess independent predictors of disease-specific survival (DSS). Mortality rates were estimated using Kaplan-Meier analyses. A total of 14,130 patients met inclusion criteria with the following histologies: UCC (90.1%), SCC (4.6%), AC, (2.3%), sarcoma (0.8%), small cell carcinoma (0.8%), signet ring carcinoma (0.5%), and spindle cell carcinoma (0.9%). Three-year DSS was most favorable in patients with UCC (63.7%; 95% confidence interval [62.9%-64.8%]) and AC (65.3% [59.3%-70.6%]), whereas 3-year DSS was the least favorable for small cell carcinoma (41.6% [31.3%-51.6%]) and sarcoma (45.4% [35.1%-55.1%]). In the multivariable analysis, independent predictors of DSS were age, marital status, grade, T-stage, N-stage, and variant histology. With respect to UCC, there was an increased risk of disease-specific death associated with all variants except AC. Sarcoma and spindle cell carcinoma were associated with the highest risk of death. With the exception of AC, the most common variant bladder cancer histologies are all independently associated with worse DSS relative to UCC in patients undergoing radical cystectomy.

Approximately 15% to 30% of patients with pT1-2N0M0 urothelial carcinoma of the bladder experience disease progression despite radical cystectomy with curative intent. We determined whether p53 expression would improve the prediction of disease progression after radical cystectomy for pT1-2N0M0 UCB. In a multi-institutional retrospective cohort we identified 324 patients with pT1-2N0M0 urothelial carcinoma of the bladder who underwent radical cystectomy. Analysis focused on a testing cohort of 272 patients and an external validation of 52. Competing risks regression models were used to test the association of variables with cancer specific mortality after accounting for nonbladder cancer caused mortality. In the testing cohort 91 patients (33.5%) had altered p53 expression (p53alt). On multivariate competing risks regression analysis altered p53 achieved independent status for predicting disease recurrence and cancer specific mortality (each p <0.001). Adding p53 increased the accuracy of multivariate competing risks regression models predicting recurrence and cancer specific mortality by 5.7% (62.0% vs 67.7%) and 5.4% (61.6% vs 67.0%), respectively. Alterations in p53 represent a highly promising marker of disease recurrence and cancer specific mortality after radical cystectomy for urothelial carcinoma of the bladder. Analysis confirmed previous findings and showed that considering p53 can result in substantial accuracy gains relative to the use of standard predictors. The value and the level of the current evidence clearly exceed previous proof of the independent predictor status of p53 for predicting recurrence and cancer specific mortality.

Evaluating the learning curve for robot-assisted laparoscopic radical cystectomy.

We seek to describe the learning curve of robot-assisted laparoscopic radical cystectomy by evaluating some of the surgical, oncologic, and clinical outcomes in our initial experience with 50 consecutive patients undergoing this novel procedure. Fifty consecutive patients (representing our initial experience with robot-assisted cystectomy) underwent radical cystectomy and urinary diversion from January 2006 to December 2007. Several different metrics were used to evaluate the learning curve of this procedure, including estimated blood loss (EBL), operative (OR) time, pathologic outcomes, and complication rate. We evaluated patients as a continuous variable, divided into five distinct time periods (quintiles), and stratified by first half and second half of robotic experience. EBL was not significantly lower until the third quintile (patients 21-30), after which further significant reductions were not observed. Mean OR time declined between each quintile for the first 30 patients (1-10 v 11-20 v 21-30). No significant declines occurred after the third quintile (21-30). When evaluated as a continuous variable, the statistical cut point at which no further significant reductions were observed was after patient 20 for OR time. No differences were observed with regard to time to flatus, bowel movement, or hospital discharge. Furthermore, complications were not different between the initial 25 patients and the most recent patients. There has been no case of a positive margin, and there was only one inadvertent bladder entry. Lymph node yield has also not significantly changed over time. This report helps to define the learning curve associated with robot-assisted laparoscopic radical cystectomy for bladder cancer. Despite the higher OR times and blood loss that is observed early in the learning curve, no such compromises are observed with regard to these oncologic parameters even early in the experience.

To identify predictive factors underlying recurrence and survival after partial cystectomy for pelvic lymph node-negative muscle-invasive bladder cancer (MIBC) (urothelial carcinoma) and to report the results of partial cystectomy among select patients. We retrospectively reviewed 101 cases that received partial cystectomy for MIBC (pT2-3N0M0) between 2000 and 2010. The log-rank test and a Cox regression analyses were performed to identify factors that were predictive of recurrence and survival. With a median follow-up of 53.0 months (range 9-120), the 5-year overall survival (OS), cancer-specific survival (CSS) and recurrence-free survival (RFS) rates were 58%, 65% and 50%, respectively. A total of 33 patients died of bladder cancer and 52 patients survived with intact bladder. Of the 101 patients included, 55 had no recurrence, 12 had non-muscle-invasive recurrence in the bladder that was treated successfully, and 34 had recurrence with advanced disease. The multivariate analysis showed that prior history of urothelial carcinoma (PH.UC) was associated with both CSS and RFS and weakly associated with OS; lymphovascular invasion (LVI) and ureteral reimplantation (UR) were associated with OS, CSS and RFS. Among patients with pelvic lymph node-negative MIBC, PH.UC and UR should be considered as contraindications for partial cystectomy, and LVI is predictive of poor outcomes after partial cystectomy. Highly selective partial cystectomy is a rational alternative to radical cystectomy for the treatment of MIBC with negative pelvic lymph nodes. Copyright © 2013 Elsevier Ltd. All rights reserved.

In radical cystectomy, the surgeon generally ligates the umbilical artery at its origin. This artery may give rise to several arteries that supply the sexual organs. Our aim was to evaluate pelvic and perineal devascularisation in women after total cystectomy. We carried out a prospective anatomical and radiological study. We performed bilateral pelvic dissections of fresh adult female cadavers to identify the dividing branches of the umbilical artery. In parallel, we examined and compared the pre- and postoperative imaging investigations [magnetic resonance imaging (MRI) angiography] in patients undergoing cystectomy for benign disease to quantify the loss of pelvic vascularisation on the postoperative images by identifying the occluded arteries. The anatomical study together with the radiological study visualised 35 umbilical arteries (n = 70) with their branching patterns and collateral arteries. The uterine artery originated from the umbilical artery in more than 75% of cases (n = 54) of the internal pudendal artery in 34% (n = 24) and the vaginal artery in 43% (n = 30). The postoperative MRI angiograms showed pelvic devascularisation in four patients. Devascularisation was dependent on the level of surgical ligation. In the four patients with loss of pelvic vascular supply, the umbilical artery had been ligated at its origin. The umbilical artery gives rise to various branches that supply the pelvis and perineum. If the surgeon ligates the umbilical artery at its origin during total cystectomy, there is a significant risk of pelvic and perineal devascularisation.

Urologic malignancies are often diagnosed at an older age, and are increasingly managed utilizing robotic-assisted surgical techniques. As such, we assessed and compared peri-postoperative complication rates following robotic urologic surgery in elderly and younger patients. A retrospective analysis of IRB-approved databases and electronic medical records identified patients who underwent robotic-assisted urologic surgery between December 2003-September 2013. Patients were grouped according to surgical procedure (partial nephrectomy, radical cystectomy, radical prostatectomy) and age at surgery (≤ 74 or ≥ 75 years old). Associations between age, comorbidities, Charlson comorbidity index (CCI), and patient outcomes were evaluated within each surgery type. 97.5% and 2.5% of patients were ≤ 74 or ≥ 75 years old, respectively. Cystectomies, partial nephrectomies and prostatectomies accounted for 3.5%, 9.5% and 87.1% of surgeries, respectively. Within cystectomy, nephrectomy and prostatectomy groups, 24.4%, 12.5% and 0.6% patients were ≥ 75 years old. Within each surgical type, elderly patients had significantly elevated CCI scores. Length of stay was significantly prolonged in elderly patients undergoing partial nephrectomy or prostatectomy. In elderly cystectomy, partial nephrectomy and prostatectomy patients, 36.7%, 14.3% and 5.9% suffered ≥ 1 Clavien grade 3-5 complication, respectively. Major complications were not significantly different between age groups. A qualitatively similar pattern was observed regarding Clavien grade 1-2 complications. The risks of robotic-assisted urologic surgery in elderly patients are not significantly elevated compared to younger patients.

Background/Aim: Studies comparing health-related quality of life (HR-QoL) between patients who underwent radical cystectomy (RC) and those who underwent a different form of urinary diversion has not reached yet univocal and reliable conclusions. The aim of our study was to evaluate bladder-specific long-term HR-QoL after radical cystectomy and ileal conduit. Patients and Methods: A multicenter study was carried out on 145 consecutive patients (112 males and 33 females) undergoing RC and ileal conduit (IC). HR-QoL assessment was conducted using Italian versions of European Organisation for Research and Treatment of Cancer QLQ-C30 and EORTC BLM-30 questionnaires. Results: Our data showed that women who underwent IC presented greater problems than men in cognitive functioning (mean score±SD: 77.3±27.9 vs. 87.8±18.6) as well in future perspective (score: 42.4±34.4 vs. 21.9±24.6). Nevertheless, men undergoing IC had more problems in sexual functioning than women (score: 23.3±24.5 vs. 7.0±20.3) (all p<0.05). Conclusion: In our series, female patients presented a greater burden than male patients in cognitive functioning as well in future perspective, but lower concerns with regard to sexual function.

To evaluate the clinical benefit of adjuvant platinum-based chemotherapy after radical cystectomy for muscle-invasive bladder cancer in routine clinical practice. The present observational study was carried out to compare the effectiveness of adjuvant chemotherapy versus observation post-radical cystectomy in patients with clinically muscle-invasive bladder cancer. Cancer-specific survival and overall survival between the adjuvant chemotherapy group and radical cystectomy alone group were compared using Kaplan-Meier method and log-rank test. After adjusting for background factors using propensity score weighting, differences in cancer-specific survival and overall survival between these two groups were compared. Subgroup analyses by the pathological characteristics were carried out. In total, 322 patients were included in the present study. Of these, 23% received adjuvant chemotherapy post-radical cystectomy. Clinicopathological characteristics showed that patients in the adjuvant chemotherapy group were pathologically more advanced and were at higher risk than the radical cystectomy alone group. In the unadjusted population, although it is not significant, the adjuvant chemotherapy group had lower overall survival (3-year overall survival; 61.5% vs 73.6%, HR 1.33, P = 0.243, log-rank test, adjuvant chemotherapy vs radical cystectomy alone). In the weighted propensity score analysis, although it is not significant, the adjuvant chemotherapy group were superior to radical cystectomy alone groups (overall survival: HR 0.65, 95% CI 0.39-1.09, P = 0.099, log-rank test, adjuvant chemotherapy vs radical cystectomy alone). Subgroup analyses showed that adjuvant chemotherapy significantly reduced the hazard ratio of overall survival and cancer-specific survival in the ≥pT3, pN+, ly+ and v+ subgroups. Platinum-based adjuvant chemotherapy might be associated with increased cancer-specific survival and overall survival in patients with high-risk invasive bladder cancer. © 2017 The Japanese Urological Association.

Purpose: We have previously reported on the mortality, morbidity, and 5-year survival of 458 patients who underwent radical radiotherapy or surgery for invasive bladder cancer in Yorkshire from 1993 to 1996. We aim to present the 10-year outcomes of these patients and to reassess factors predicting survival. Methods and Materials: The Northern and Yorkshire Cancer Registry identified 458 patients whose cases were subjected to Kaplan-Meier all-cause survival analyses, and a retrospective casenote analysis was undertaken on 398 (87%) for univariate and multivariate Cox proportional hazards modeling. Additional proportional hazards regression modeling was used to assess the statistical significance of variablesmore » on overall survival. Results: The ratio of radiotherapy to cystectomy was 3:1. There was no significant difference in overall 10-year survival between those who underwent radiotherapy (22%) and radical cystectomy (24%). Univariate analyses suggested that female sex, performance status, hydronephrosis and clinical T stage, were associated with an inferior outcome at 10 years. Patient age, tumor grade, treatment delay, and caseload factors were not significant. Multivariate analysis models were created for 0-2 and 2-10 years after treatment. There were no significant differences in treatment for 0-2 years; however, after 2 years follow-up there was some evidence of increased survival for patients receiving surgery compared with radiotherapy (hazard ratio 0.66, 95% confidence interval: 0.44-1.01, p = 0.06). Conclusions: a 10-year minimum follow-up has rarely been reported after radical treatment for invasive bladder cancer. At 10 years, there was no statistical difference in all-cause survival between surgery and radiotherapy treatment modalities.« less

To evaluate whether anti-inflammatory agents affect outcomes in patients receiving intravesical BCG therapy for high-grade (HG) non-muscle-invasive bladder cancer (NMIBC). We reviewed the records of 203 patients in a prospective database of HG NMIBC from 2006 to 2012 at a single institution. Patients who had muscle-invasive disease (n = 32), low-grade pathology (n = 4), underwent early cystectomy within 3 months (n = 25), had <3 months of follow-up (n = 11), or did not receive an induction course of intravesical BCG (n = 32) were excluded. Clinicopathologic data were tabulated including demographics, comorbidities, pathologic stage and grades, intravesical therapy, and concomitant use of aspirin, NSAIDs, COX inhibitors, and statins. Multivariate Cox regression analysis explored predictive factors for recurrence, progression (stage progression or progression to cystectomy), cancer-specific survival (CSS), and overall survival (OS). Ninety-nine patients with HG NMIBC who received at least one induction course of intravesical BCG were identified, with median follow-up of 31.4 months. There were 20 (20.2 %) deaths, including 6 (6.1 %) patients with bladder cancer-related mortality. 13 % patients experienced tumor progression and 27 % underwent cystectomy following failure of intravesical therapy. Anti-inflammatory use included statins (65 %), aspirin (63 %), or non-aspirin NSAIDs/COX inhibitors (26 %). Anti-inflammatory use was not significantly predictive of recurrence, progression, or mortality outcomes on Cox regression. CIS stage was associated with higher progression, while age, BMI, and Charlson score were independent predictors of overall mortality. Despite speculation of inhibitory effects on BCG immunomodulation there was no evidence that anti-inflammatory agents impacted oncologic outcomes in patients receiving BCG for HG NMIBC.

Does the live birth rate after IVF depend on the etiology of diminished ovarian reserve (DOR)? IVF outcome and live birth rate are significantly impaired in women with DOR caused by a previous cystectomy for endometrioma compared with women with idiopathic DOR. The safety of the surgical treatment of endometriomas is being discussed in terms of damage to ovarian reserve. Several studies have reported a poor response to controlled ovarian stimulation and a significantly impaired IVF outcome in women with DOR consecutive to an endometrioma cystectomy compared with women with tubal factor infertility. Retrospective case-control study conducted in women aged under 40 treated in our Reproductive Medicine Center between January 2010 and January 2014 for a DOR defined by anti-Müllerian hormone level <2 ng/ml. Two groups of patients were selected: group A included patients with a DOR diagnosed after cystectomy(s) for endometrioma(s), group B included patients with an idiopathic DOR. In each group, subgroups of patients 'poor ovarian responders', based on the ESHRE criteria ('Bologna criteria'), have been established. A total of 51 patients in group A were matched to 116 patients in group B, representing respectively 125 and 243 IVF cycles. Among them, 39 patients in group A and 78 patients in group B validated strictly by the Bologna criteria, representing 99 and 189 IVF cycles, respectively. Each patient underwent a controlled ovarian hyperstimulation and IVF with fresh embryo transfer. Primary end-point was the live birth rate. Secondary end-points were the number of retrieved oocytes, fertilization rate, implantation rate, clinical pregnancy rate, spontaneous abortion rate and cycle cancelation rate. Significantly lower pregnancy (11.2% in group A versus 20.6% in group B, P = 0.02) and live birth (7.2 versus 16.9% respectively, P = 0.01) rates per cycle were assessed in women in group A compared with women in group B. The same results were obtained in the Bologna criteria subgroup analysis with a significantly lower pregnancy (9.1 versus 20.1%, P = 0.016) and live birth (5.1 versus 15.3%, P = 0.001) rates per cycle in women in subgroup A compared with women in subgroup B. Patients in group A required significantly higher gonadotrophins doses (2881 IU ± 1111 versus 2526 IU ± 795, P = 0.005), longer ovarian stimulation (10.6 Days ± 2.8 versus 9.9 Days ± 2.4, P = 0.019) and higher cancelation rate for poor response (12 versus 6.2%, P = 0.05). Despite a mean number of retrieved oocytes similar with the group B (5.4 ± 3.1 and 5.1 ± 3.2, NS), and a significantly higher fertilization rate (65.7 versus 47.2%, P < 0.001), women in group A showed a significantly lower implantation rate (7.2 versus 13.5%, P = 0.03). Abortion rate, ectopic pregnancy rate and multiple pregnancy rate were similar in both groups. Data were collected retrospectively using the database of our Department. Sample size is relatively small but our study provides statistically significant evidence that the chances of IVF success are decreased in women with DOR after cystectomy for endometrioma. Further larger series are needed to confirm these findings. To our knowledge, this is the first study evaluating IVF outcome in patients with DOR after cystectomy(s) for endometrioma(s) versus in patients with an idiopathic DOR. In addition to the risk of damaging ovarian reserve, we hypothesize that endometrioma surgery would not have qualitative benefits on results in IVF in patients with DOR.

Mortality from radical cystectomy is still high, in some series accounting for 1-10% deaths. Morbidity is even higher and can reach 50%. This paper contributes the case of a 66-year old male patient diagnosed with an infiltrant tumour of the bladder following TUR. The patient's background included prior surgery for gastroduodenal ulcus, alcohol consumption, and obesity. Following routine pre-operatory investigations, the patient underwent radical cystectomy using routine techniques and urinary by-pass via transcolonic ureterosigmoidostomy. Increased transaminases, leucocytosis, vomiting, jaundice and extended intestinal ileum were noted during the patient's post-operative period, while blood and urine amylase concentrations were moderately high. Following CAT study, laparotomy was performed and the diagnosed confirmed. The patient died on day 14 of surgery due to secondary pulmonary complications. Post-operative pancreatitis is a low-frequency, high-mortality acknowledged complication. Even though most cases are secondary to biliarypancreatic and surrounding pancreas area surgery, it has also been described in some instances of distant surgery such as the present case. Alcohol consumption, biliary lithiasis, prior cholecystectomy and diabetes are predisposing factors. High amylase values do not always accompany this condition. Early diagnosis and treatment are crucial for the patient's prognosis. Respiratory complications are the usual cause of death in these patients.

Several recent preliminary reports have demonstrated that Robot-Assisted Cystectomy with total intracorporeal Ileal Conduit (RACIC) is a feasible option over the open technique. We report our stepwise surgical procedure of robotic total intracorporeal ileal conduit urinary diversion, technical consideration, development, refinements and initial experience. Only the ileal conduit urinary diversion is described with no emphasis on the cystectomy's steps. Between February 2008 and September 2009, nine patients underwent RACIC for muscle invasive transitional cell carcinoma (TCC). The entire procedure, including radical cystoprostatectomy, extended pelvic node dissection (ePLND), ileal conduit urinary diversion (Bricker) including isolation of the ileal loop (20 cm ileal segment) 15 cm away from the ileocecal junction, restoration of bowel continuity with stapled side-to-side ileo-ileal anastomosis, retroperitoneal transfer of the left ureter to the right side, and bilateral stented (8 F feeding tube) ileo-ureteral anastomoses in a Wallace faction were all performed exclusively intracorporeally using the da Vinci Si surgical robot and finally the conduit stoma was fashioned. The RACIC was technically successful in all nine patients (three females and six males. Mean age 74.1; 57 to 87) without open conversion. The mean operative time including extended pelvic lymphadenectomy and urinary diversion was 346.2 minutes (210 to 480). Mean operative time of diversion is 72 minutes (52-113) mean estimated blood loss 258 mL (200 to 500) and the median hospital stay were 14 days (10 to 27). In all three female patients, the specimen was extracted through the vagina. There were no intraoperative complications and only one major postoperative complication: one postoperative iatrogenous necrosis of the ileal conduit caused by uncareful retraction of the organ bag and thereby probably injuring the conduit pedicle, as the ileal conduit was well vascularised at the end of the operation, requiring an open revision (in male patient extracted through the suprapubic incision). A clear liquid diet was started on the third postoperative day. All patients returned to normal activity within 2 weeks (from date of surgery). Postoperative renal function was normal with mean postoperative creatine 0.99 mg/dL) and excretory urography revealed unobstructed upper tracts in all cases. Robot-assisted radical cystoprostatectomy with intracorporeal ileal conduit urinary diversion for the treatment of high risk or invasive bladder cancer with urinary diversion is technically feasible. The robotic system aids in performing a meticulous dissection and all operative steps of the open procedure are replicated precisely while adhering to the sound oncologic principles of traditional radical cystectomy. Robotics brings an unprecedented control of surgical instruments, shorten the learning curve, and allow open surgeons to apply more easily their technical skill in a minimal invasive fashion. Robotic cystectomy with total intracorporeal ileal conduit urinary diversion offers operative and perioperative benefits and functional outcome. In our hands results comparable to open experience with further reduced perioperative morbidity, early recovery, resumption of normal activities, excellent cosmesis and increased quality of life (QOL). In addition, minimal blood loss, fluid shifts, and electrolyte loss considerably reduce systemic and cardiovascular stress in these older groups of patients.

Radical cystectomy with extended lymphadenectomy is the surgical treatment of choice for muscle-invasive bladder cancer. The technical and technological improvements and the positive results from robot-assisted kidney and prostate surgery have led to the progressive development of robot-assisted radical cystectomy (RARC). We provide a global structured overview and an update on the complications of RARC, recorded according to the Clavien-Dindo classification system. We conducted a search on PubMed of all publications on RARC to date (2014). Of the 259 publications found, we excluded review articles and cost analyses, publications with less than 30 cases, updates of previous studies and those whose main objective was the study of other issues related to RARC other than complications, leaving a total of 38 articles for the final analysis. The most common complications associated with RARC are gastrointestinal, infectious and genitourinary system, mainly Clavien 1-2, followed by Clavien 3-4. RARC had lower overall complication rates than open radical cystectomy and laparoscopic radical cystectomy and had a lower incidence of severe complications, less intraoperative bleeding and better postoperative recovery. Although further scientific evidence is needed, RARC is an increasingly widespread technique that appears to reduce complications as well as the need for transfusion, and it improves recovery times.

We evaluated short- and long-term renal function in patients after radical cystectomy with urinary diversion and identified risk factors for the deterioration of renal function. This retrospective study comprised 91 patients who underwent radical cystectomy and urinary diversion for bladder cancer and survived ≥3 years after surgery. The estimated glomerular filtration rate (eGFR) was calculated, and longitudinal changes of eGFR were assessed. Deterioration in renal function in early and late postoperative years was defined as a ≥25 % decrease in the eGFR from preoperative to postoperative year one, and a reduction in the eGFR of >1 mL/min/1.73 m 2 annually in subsequent years, respectively. Univariate and multivariate logistic regression analyses were used to evaluate its association with clinicopathologic features. The median follow-up period after surgery was 7 years (range 3-26). The mean eGFR decreased from preoperative 65.1 to 58.9 mL/min/1.73 m 2 1 year after the surgery, followed by a continuous decline of ~1.0 mL/min/1.73 m 2 per year thereafter. Multivariate analyses identified ureteroenteric stricture as the sole risk factor associated with early renal function deterioration [odds ratio (OR) 4.22, p = 0.037]. Diabetes mellitus (OR 8.24, p = 0.015) and episodes of pyelonephritis (OR 4.89, p = 0.038) were independently associated with the gradual decline in the late postoperative period. In cystectomy patients with urinary diversion, the rapid deterioration of renal function observed during the first year after surgery and the gradual but continuous decline in function thereafter were found to be associated with different risk factors.

Radical cystectomy is the standard treatment for localised muscle invasive bladder cancer (MIBC). We offer a bladder-sparing treatment with TURB +/- Chemotherapy+Radiotherapy to selected patients as an alternative. We analyze, retrospectively, 30 patients diagnosed with MIBC from March 1991 to October 2010. The mean age was 62.7 years (51-74). All patients were candidates for a curative treatment, and underwent strict selection criteria: T2 stage, primary tumor, solitary lesion smaller than 5cm with a macroscopic disease-free status after TURB, negative random biopsy without hydronephrosis. Staging CT evaluation was normal. Restaging TURB or tumor bed biopsy showed a disease-free status or microscopic muscle invasion. 14 patients underwent TURB alone, 13 TURB+Chemotherapy and 3 TURB+Chemotherapy+Radiotherapy. The mean follow up was 88.7 months (19-220). 14 patients remained disease free (46.6%), 10 had recurrent non-muscle invasive bladder cancer (33%). 81.3% complete clinical response. 71% bladder preserved at 5-years. Overall, 5-years survival rate was 79% and 85% cancer-specific survival rate. Although radical cystectomy is the standard treatment for localised MIBC, in strictly selected cases, bladder-sparing treatment offers an alternative with good long term results.

To compare health-related quality-of-life (HRQoL) outcomes for robot-assisted laparoscopic radical cystectomy (RARC) with those of traditional open radical cystectomy (ORC) in a prospective randomised fashion. This was a prospective randomised clinical trial evaluating the HRQoL for ORC vs RARC in consecutive patients from July 2009 to June 2011. We administered the Functional Assessment of Cancer Therapy-Vanderbilt Cystectomy Index questionnaire, validated to assess HRQoL, preoperatively and then at 3, 6, 9 and 12 months postoperatively. Scores for each domain and total scores were compared in terms of deviation from preoperative values for both the RARC and the ORC cohorts. Multivariate linear regression was used to assess the association between the type of radical cystectomy and HRQoL. At the time of the study, 47 patients had met the inclusion criteria, with 40 patients being randomised for analysis. The cohorts consisted of 20 patients undergoing ORC and 20 undergoing RARC, who were balanced with respect to baseline demographic and clinical features. Univariate analysis showed a return to baseline scores at 3 months postoperatively in all measured domains with no statistically significant difference among the various domains between the RARC and the ORC cohorts. Multivariate analysis showed no difference in HRQoL between the two approaches in any of the various domains, with the exception of a slightly higher physical well-being score in the RARC group at 6 months. There were no significant differences in the HRQoL outcomes between ORC and RARC, with a return of quality of life scores to baseline scores 3 months after radical cystectomy in both cohorts. © 2014 The Authors.

Objectives To investigate the relation between volume and mortality after adjustment for case mix for radical cystectomy in the English healthcare setting using improved statistical methodology, taking into account the institutional and surgeon volume effects and institutional structural and process of care factors. Design Retrospective analysis of hospital episode statistics using multilevel modelling. Setting English hospitals carrying out radical cystectomy in the seven financial years 2000/1 to 2006/7. Participants Patients with a primary diagnosis of cancer undergoing an inpatient elective cystectomy. Main outcome measure Mortality within 30 days of cystectomy. Results Compared with low volume institutions, medium volume ones had a significantly higher odds of in-hospital and total mortality: odds ratio 1.72 (95% confidence interval 1.00 to 2.98, P=0.05) and 1.82 (1.08 to 3.06, P=0.02). This was only seen in the final model, which included adjustment for structural and processes of care factors. The surgeon volume-mortality relation showed weak evidence of reduced odds of in-hospital mortality (by 35%) for the high volume surgeons, although this did not reach statistical significance at the 5% level. Conclusions The relation between case volume and mortality after radical cystectomy for bladder cancer became evident only after adjustment for structural and process of care factors, including staffing levels of nurses and junior doctors, in addition to case mix. At least for this relatively uncommon procedure, adjusting for these confounders when examining the volume-outcome relation is critical before considering centralisation of care to a few specialist institutions. Outcomes other than mortality, such as functional morbidity and disease recurrence may ultimately influence towards centralising care. PMID:20305302

To improve quality of life in postcystectomy patients, we made 150 radical cystectomies with recovery of urethral voiding. Cystectomy was performed by a modified technique in 87 of 135 operated men: transprostatic cystvesiculectomy (n = 11), transprostatic cystectomy (n = 53), supraprostatic cystectomy (n = 23). Indication for this modification was the absence of extravesicular growth of the primary tumor and prostatic cancer. Monitoring of radicalism was carried out by intraoperative urgent histological investigation of the resection line. 74 patients have undergone retrograde cystectomy. Postoperative lethality was 2.3%. 9 month and longer follow up results were studied.

To update our previous analysis of the clinical and pathological impact of the change in the submission of lymphadenectomy specimens from en bloc to 13 separate anatomically defined packets, which took place at the University of Southern California in May 2002, and to determine whether lymph node (LN) packeting resulted in any change in oncological outcomes. A total of 846 patients who underwent radical cystectomy (RC) with super-extended LN dissection for cTxN0M0 bladder cancer between January 1996 and December 2007 were identified. Specimens of 376 patients were sent en bloc (group 1), and specimens of 470 patients were sent in 13 separate anatomical packets (group 2). The pathological tumour stage distribution and the proportion of LN-positive patients (group 1: 82 patients [22%] versus group 2: 99 patients [21%]; P = 0.80) were similar between the two groups: the median [range] number of total LNs identified increased significantly (group 1: 32 [10-97] versus group 2: 65 [10-179]; P < 0.001). LN density decreased (group 1, 11% versus group 2, 4%; P = 0.005). The median [range] number of positive LNs removed was similar (group 1: 0 [0-30] versus group 2: 0 [0-97]; P = 0.87). No nodal stage shift was observed. The 5-year overall survival (group 1: 58% versus group 2: 59%; P = 0.65) and recurrence-free survival rates (group 1: 68% versus group 2: 70%; P = 0.57) were similar. The incidence of patients with positive LNs remained unchanged, regardless of how the LN specimen was submitted. Submitting 13 separate nodal packets significantly increased the total LN yield, but did not result in a significant increase in the number of positive LNs or a consecutive nodal stage shift and did not affect oncological outcomes. Based on these results LN density is not an accurate prognosticator. © 2014 The Authors BJU International © 2014 BJU International Published by John Wiley & Sons Ltd.

In recent years, the laparoscopic approach in oncologic urology seems more attractable to the surgeons. It is considered to have the same oncologic quality as open surgery, but is less invasive in patients. It is used widely in all of Europe, but with various frequency. The aim of the study was to present a various amount of oncourological procedures from three neighbouring countries - Poland, Czech Republic and Hungary. Prostatectomy, cystectomy, nephrectomy and tumorectomy (Nephron Sparing Procedures - NSS) were presented as a list of procedures prepared from the national registry. The total amount of procedures was presented, as well as the LO (Lap to Open procedures) index, P/P (procedures/population) index, ratio of cystectomy/population, and cystectomy/TURBT. In the Czech Republic, the most complex procedures are performed (laparoscopic/robotic prostatectomy, NSS LAP, LAP nephrectomy) in the majority when analysing the country's population. In Hungary and Czech Republic, there are more laparoscopic/robotic radical prostatectomies performed, than open ones. In Poland the largest number of cystectomies is performed when analysing the country's population, but it is difficult to explain the much higher ratio of 6.57 TUR/one cystectomy. In the Czech Republic this procedure is performed in almost one quarter of the patients (23.36%). Interestingly, in Hungary the cystectomy with pouch creation is performed in about 67.65% cases. The highest reimbursement for surgical procedure is present in the Czech Republic with approximately 20-40% more than when compared to Poland or Hungary. The definitive leader in Central Europe (based on the national registry) is the Czech Republic, where the most complex procedures are performed (laparoscopic/robotic prostatectomy, NSS LAP, LAP nephrectomy) in biggest amounts when analysing the country's population. Explanation of such circumstances, can be the higher reimbursement rate for surgical procedure in this country.

Married (vs. unmarried) individuals have improved health status and longer life expectancies in a variety of benign and malignant disease states, including prostate, breast, head/neck, and lung cancers. We sought to evaluate a cohort of patients undergoing cystectomy for bladder cancer to evaluate the impact of marital status on demographic, peri-operative, and pathological outcomes in order to better understand the factors which may contribute to the survival differences observed. Two-hundred and two patients underwent radical cystectomy and urinary diversion for bladder cancer. Patients were categorized based on marital status as either married or unmarried (widowed, divorced, never married). Correlations were made to demographic factors (age, race, gender, BMI, tobacco use, alcohol use), perioperative factors (pre-op renal function (creatinine), hematocrit, EBL, hospital stay, choice of diversion), and pathological outcomes (organ-confined status, LN positivity). Of the 202 patients, 74% were married. Married individuals (vs. unmarried) were more often male (84 vs. 62%) and had a higher BMI (28.1 vs. 25.9). Married persons had a significantly lower pre-op creatinine (1.1 vs. 1.4) and higher hematocrit (39 vs. 34). Hospital stay was shorter in married patients by a mean of 1.6 days. Regarding operative pathology, married patients had a higher rate of organ-confined disease (59 vs. 47%) (P = 0.05, 0.08 on multivariate) and trended towards a lower rate of LN positivity (15 vs. 21%; P = 0.10, 0.12 multivariate). In patients undergoing cystectomy for bladder cancer, married individuals appear to have improved pre-operative laboratory variables, shorter hospitalization, and improved pathological outcomes versus unmarried patients in our case series. These findings may support the evidence (observed in other tumor types and other disease states) that married persons present earlier than unmarried individuals, and this may help explain the improved survival outcomes that have been observed in married patients with bladder cancer.

Purpose: To present outcomes of bladder-preserving therapy with proton beam irradiation in patients with invasive bladder cancer. Methods and Materials: Twenty-five patients with transitional cell carcinoma of the urinary bladder, cT2-3N0M0, underwent transurethral resection of bladder tumor(s), followed by pelvic X-ray irradiation combined with intra-arterial chemotherapy with methotrexate and cisplatin. Upon completion of these treatments, patients were evaluated by transurethral resection biopsy. Patients with no residual tumor received proton irradiation boost to the primary sites, whereas patients demonstrating residual tumors underwent radical cystectomy. Results: Of 25 patients, 23 (92%) were free of residual tumor at the time of re-evaluation; consequently,more » proton beam therapy was applied. The remaining 2 patients presenting with residual tumors underwent radical cystectomy. Of the 23 patients treated with proton beam therapy, 9 experienced recurrence at the median follow-up time of 4.8 years: local recurrences and distant metastases in 6 and 2 patients, respectively, and both situations in 1. The 5-year overall, disease-free, and cause-specific survival rates were 60%, 50%, and 80%, respectively. The 5-year local control and bladder-preservation rates were 73% and 96%, respectively, in the patients treated with proton beam therapy. Therapy-related toxicities of Grade 3-4 were observed in 9 patients: hematologic toxicities in 6, pulmonary thrombosis in 1, and hemorrhagic cystitis in 2. Conclusions: The present bladder-preserving regimen for invasive bladder cancer was feasible and effective. Proton beam therapy might improve local control and facilitate bladder preservation.« less

To develop a Korean version of the Functional Assessment of Cancer Therapy (FACT)-Vanderbilt Cystectomy Index (VCI) from the original English version, with subsequent linguistic validation in Korean patients who underwent radical cystectomy with urinary diversion. Translation and linguistic validation were carried out between January and May of 2013, which consisted of the following stages:(1) permission for translation;(2) forward translation;(3) reconciliation;(4) backward translation;(5) cognitive debriefing and(6) final proof-reading. During the forward translation phases,word as such as "bother","spend time", "support", "coping" and "concern" were adjusted to be more comprehensible to the target population. There conciled Korean version was accepted without certain objections because the original version and the backward translation were almost congruent except for minor differences in a subset of questions. The translation was tested using 5 Korean-speaking subjects. The subjects took an average of 8.2 minutes to complete the questionnaire, without difficulty and found the questionnaire clear and easy to understand. The panel discussed each of the issues raised by subjects and most terms were judged by the panel as to not require further changes because the overall comprehension levels were relatively high and because the translated terms were accurately rendered in the target languages. This report has demonstrated that despite translation difficulties, the linguistic validation of the FACT-VCI in the Korean language was successful. The next step is to assess the psychometric properties of the Korean version of FACT-VCI.

Lymph node-positive bladder cancer is a systemic disease in the majority of patients. Adjuvant chemotherapy given shortly after surgery, when tumor burden is low, seems reasonable, yet there is no proof that it improves survival. In this retrospective study, we compare the outcomes of patients with microscopic lymph node positive bladder cancer (pN1 or pN2) treated with radical cystectomy followed by adjuvant chemotherapy and those who declined chemotherapy. Sixty-seven patients with lymph node positive bladder cancer (26 pN1 and 41 pN2) who underwent radical cystectomy between April 1995 and April 2005 were reviewed. Combined adjuvant chemotherapy (gemcitabine and cisplatin in most patients) was given to 35 patients (52%), but declined by 32 (48%). The two groups were similar in performance status, postoperative complication rate, and N stage but deferring patients were on average 5 years older and had a more advanced T stage. Study primary endpoint was overall survival (OS). Adjuvant chemotherapy was well tolerated and 28/35 patients (80%) completed all 4 cycles. Median OS of patients given adjuvant chemotherapy was 48 months compared with 8 months for declining patients (hazard ratio 0.13, 95% CI 0.04-0.4, P < 0.0001). Multivariate age adjusted analysis showed that adjuvant chemotherapy was an independent factor affecting OS (hazard ratio 0.2, P < 0.0001). This study supports the use of adjuvant chemotherapy after radical cystectomy in patients with node positive bladder cancer. Study design and patient imbalances make it impossible to draw definitive conclusions.

To evaluate the impact on ovarian reserve between two different methods ofhemostasis after laparoscopic ovarian endometrioma excision. A randomized controlled study was conducted from January to December 2013 in Thammasat University Hospital, Thailand. Reproductive women, age 18-45years who underwent laparoscopic ovarian cystectomy were randomized in electrocoagulation and suture groups. Clinical baseline data and ovarian reserve outcome (anti-Mullerian hormone (AMH)) were evaluated. Fifty participants were recruited and randomized in two groups. Electrocoagulation and suture groups consisted of 25 participants. Baseline characteristics between 2 groups (age, weight, BMI, height, cyst diameter, duration and estimated blood loss) were not statistically different. There were no significant difference of AMIH between electrocoagulation and suture group atpre-operative (2.90±2.26 vs. 2.52±2.37 ng/ml), 1 week (1.78±1.51 vs. 1.99±1.71 ng/ml), 1 month (1.76±1.50 vs. 2.09±1.62 ng/ml), 3 months (2.09±1.66 vs. 1.96±1.68 ng/ml) and 6 months (2.11±1.84 vs 1.72±1.68 ng/ml), respectively. However mean AMH ofboth groups significantly decreased since the first week of operation. Effect oflaparoscopic ovarian surgery had significantly declined and sustained AMH level until 6 months. Laparoscopic cystectomy of ovarian endometrioma has negative impact to ovarian reserve. Either electroco- agulation or suture method had no different effects.

INTRODUCTION. During the last 30 years, the multidisciplinary treatments of colon and uterus neoplasm have yielded an increase in total survival rates, fostering therefore the increase of cases with regional relapse involving the urinary tract. In these cases the iterative surgery can be performed, if no disease secondary to pelvic pain, haemostatic or debulking procedure is present, and must be considered and discussed with the patient, according to his/her general status. MATERIALS AND METHODS. From 1997 to August 2007 we performed altogether 43 pelvic iterative surgeries, with simultaneous urologic surgical procedure because of pelvic tumor relapse in patients with uterus neoplasm and colon and rectal cancer. In 4 cases of anal cancer, the urological procedure were: one radical prostatectomy with continent vesicostomy in the first case, while in the other 3 cases radical pelvectomy with double-barrelled uretero-cutaneostomy. In 23 cases of colon cancer, the urologic procedures were: 9 cases of radical cystectomy with double-barrelled uretero-cutaneostomy, 4 cases of radical cystectomy with uretero-ileo-cutaneostomy according to Bricker- Wallace II procedure, and 9 cases of partial cystectomy with pelvic ureterectomy and ureterocystoneostomy according to Lich-Gregoire technique (7 cases) and Lembo-Boari (2 cases) procedure. In 16 cases of uterus cancer, the urological procedure were: 7 cases of partial cystectomy with pelvic ureterectomy and uretero-cystoneostomy according to Lich-Gregoire procedure; in 3 cases, a radical cystectomy with urinary continent cutaneous diversion according to the Ileal T-pouch procedure; 2 cases of total pelvectomy and double uretero-cutaneostomy, and 4 cases of bilateral uretero-cutaneostomy. RESULTS. No patients died in the perioperative time; early systemic complications were: 2 esophageal candidiasis, 1 case of venous thrombosis. CONCLUSIONS. The iterative pelvic surgery in the case of oncological relapse involving the urinary tract aims to achieve the best quality of life with the utmost oncological radicality. The equation: eradication of pelvic neoplasm and urinary tract reconstruction, with acceptable quality of life, will be the future target; nevertheless, it is not possible to establish guidelines beforehand, and the therapy must be adapted to each single case.

Kinn, A.C.; Lantz, B.

1984-05-01

Vitamin B12 deficiency was found in 10 of 41 patients who underwent radiotherapy before cystectomy with Bricker urinary diversion for carcinoma of the bladder. Of 13 patients given full irradiation because of inoperable bladder cancer 5 had malabsorption of vitamin B12. Serum folic acid was normal in these patients, indicating predominantly ileal irradiation sequelae. Routine evaluation of serum vitamin B12 after radiotherapy is recommended so that appropriate medication can be given, if possible before neurological symptoms appear.

Here we report a case of a giant mature cystic teratoma of the ovary in a 38-year-old nullipaous woman. The patient presented with abdominal distension and abdominal pain. Laparotomy and cystectomy yielded satisfactory results. Histologic evaluation confirmed a benign cystic teratoma of the ovary. The patient underwent surgery for rupture of corpus luteum six years ago and no gross lesion was seen at the operation. This case demonstrates that dermoid cysts can grow to enormous sizes within a short duration. PMID:26500962

Adenocarcinoma of the vermiform appendix is a rare malignant neoplasm of the gastrointestinal tract encountered rarely within general surgical practice. We present the case of a 49-year-old man who, while undergoing investigations for haematuria, was diagnosed with an appendicular adenocarcinoma following bladder biopsy. Consequently he underwent right hemicolectomy and partial cystectomy followed by adjuvant chemotherapy. By discussing this case we hope to raise awareness within the medical profession of this rare presentation so that it may be considered within clinicians’ differential diagnoses. PMID:25358831

2014-06-01

We evaluated the effect of alvimopan treatment vs placebo on health care utilization and costs related to gastrointestinal recovery in patients treated with radical cystectomy in a randomized, phase 4 clinical trial. Resource utilization data were prospectively collected and evaluated by cost consequence analysis. Hospital costs were estimated from 2012 Medicare reimbursement rates and medication wholesale acquisition costs. Differences in base case mean costs between the study cohorts for total postoperative ileus related costs (hospital days, study drug, nasogastric tubes, postoperative ileus related concomitant medication and postoperative ileus related readmissions) and total combined costs (postoperative ileus related, laboratory, electrocardiograms, nonpostoperative ileus related concomitant medication and nonpostoperative ileus related readmission) were evaluated by probabilistic sensitivity analysis using a bootstrap approach. Mean hospital stay was 2.63 days shorter for alvimopan than placebo (mean±SD 8.44±3.05 vs 11.07±8.23 days, p=0.005). Use of medications or interventions likely intended to diagnose or manage postoperative ileus was lower for alvimopan than for placebo, eg total parenteral nutrition 10% vs 25% (p=0.001). Postoperative ileus related health care costs were $2,340 lower for alvimopan and mean total combined costs were decreased by $2,640 per patient for alvimopan vs placebo. Analysis using a 10,000-iteration bootstrap approach showed that the mean difference in postoperative ileus related costs (p=0.04) but not total combined costs (p=0.068) was significantly lower for alvimopan than for placebo. In patients treated with radical cystectomy alvimopan decreased hospitalization cost by reducing the health care services associated with postoperative ileus and decreasing the hospital stay.

Regarding the role of gas entry in abdomen and cardiorespiratory effects, the ability of anesthesiologists would be challenged in laparoscopic surgeries. Considering few studies in this area and the relevance of the subject, this study was performed to compare the arterial oxygen alterations before operation in comparison with after surgery between laparoscopic cholecystectomy and ovarian cystectomy. In this prospective cohort, 70 consecutive women aged from 20 to 60 years who were candidate for laparoscopic cholecystectomy (n = 35) and ovarian cystectomy (n = 35) with reverse (20 degrees) and direct (30 degrees) Trendelenburg positions, respectively, with ASA class I or II were enrolled. After intubation and before operation, for the first time, the arterial blood gas from radial artery in supine position was obtained for laboratory assessment. Then, the second blood sample was collected from radial artery in supine position and sent to the lab to be assessed with the same device after 30 minutes from surgery termination. The measured variables from arterial blood gas were arterial partial pressure of oxygen (PaO 2 ) and Oxygen saturation (SpO 2 ) alterations. Total PaO 2 was higher in the first measurement. The higher values of PaO 2 in cholecystectomy (upward) than in ovarian cystectomy (downward) were not significant in univariate (P = 0.060) and multivariate analysis (P = 0.654). Furthermore, higher values of SpO 2 in cholecystectomy (upward) than in ovarian cystectomy (downward) were not significant in univariate (P = 0.412) and multivariate analysis (P = 0.984). In general, based on the results of this study, the values of PaO 2 in cholecystectomy (upward) were not significantly higher than the values in cystectomy (downward) in laparoscopic surgeries when measured 30 minutes after surgery.

Radical cystectomy is inherently associated with morbidity. We assess the timing and incidence of venous thromboembolism, review current guideline recommendations and provide evidence for considering extended venous thromboembolism prophylaxis in all patients undergoing radical cystectomy. We searched PubMed® for available literature on radical cystectomy and venous thromboembolism, focusing on incidence and timing, evidence supporting extended venous thromboembolism prophylaxis in patients undergoing radical cystectomy or abdominal oncologic surgery, current guideline recommendations, safety considerations and direct oral anticoagulants. Search terms included "radical cystectomy," "venous thromboembolism," "prophylaxis," and "extended oral anticoagulants" and "direct oral anticoagulants" alone and in combination. Relevant articles were reviewed, including original research, reviews and clinical guidelines. References from review articles and guidelines were also assessed to develop a narrative review. The incidence of symptomatic venous thromboembolism in short-term followup after radical cystectomy is 3% to 11.6%, of which more than 50% of cases will occur after hospital discharge. Meta-analyses of clinical trials in patients undergoing major abdominal oncologic operations suggest a decreased risk of venous thromboembolisms for patients receiving extended (4 weeks) venous thromboembolism prophylaxis. Extended prophylaxis should be considered in all radical cystectomy cases. Although the relative risk of bleeding also increases, the overall net benefit of extended prophylaxis clearly favors use for at least 28 days postoperatively. Extrarenal eliminated prophylaxis agents are preferred given the risk of renal insufficiency in radical cystectomy cases, with newer oral anticoagulants providing an alternative route of administration. Patients undergoing radical cystectomy are at high risk for venous thromboembolism after hospital discharge. There is strong evidence that extended prophylaxis significantly decreases the risk of venous thromboembolism in oncologic surgery cases. Use of extended prophylaxis after radical cystectomy has been poorly adopted, emphasizing the need for better adherence to current urology procedure specific guidelines as extended prophylaxis for radical cystectomy is the standard of care. Specific and rare circumstances may require case by case assessment. Copyright © 2018 American Urological Association Education and Research, Inc. Published by Elsevier Inc. All rights reserved.

Purpose: To report the results of a conservative strategy based on partial surgery combined with brachytherapy in a prospective cohort of children with bladder–prostate rhabdomyosarcoma (BP RMS). Methods and Materials: We prospectively documented the outcome of children treated in our department between 1991 and 2015 for BP RMS and undergoing a multimodal approach combining conservative surgery (partial cystectomy and/or partial prostatectomy) and perioperative interstitial low-dose-rate or pulse-dose-rate brachytherapy. Before brachytherapy, children had received chemotherapy with modalities depending on their risk group of treatment. Results: A total of 100 patients were identified, with a median age of 28 months (range, 5.6 months-14more » years). According to the Intergroup Rhabdomyosarcoma Study (IRS) group, 84 were IRS-III, and 12 were IRS-IV tumors. Four patients were treated at relapse. The median number of chemotherapy cycles before local therapy was 6 (range, 4-13). After surgery, 63 patients had a macroscopic tumor residuum. Five patients underwent a brachytherapy boost before pelvic external beam radiation therapy because of nodal involvement, and 95 had exclusive brachytherapy. Median follow-up was 64 months (range, 6 months-24.5 years). Five-year disease-free and overall survival rates were 84% (95% confidence interval 80%-88%) and 91% (95% confidence interval 87%-95%), respectively. At last follow-up most survivors presented with only mild to moderate genitourinary sequelae and a normal diurnal urinary continence. Five patients required a secondary total cystectomy: 3 for a nonfunctional bladder and 2 for relapse. Conclusion: Brachytherapy is effective as part of a conservative strategy for BP RMS, with a relatively low delayed toxicity as compared with previously published studies using external beam radiation therapy. Longer follow-up is required to ensure that the functional results are maintained over time.« less

Muscle-invasive bladder cancer (MIBC) is considered one of the most lethal malignancies with high metastatic potential. Usually, metastatic bladder cancer carries worse prognosis with a median survival rate of approximately 6 months, which can be prolonged for up to 14 months with palliative systemic chemotherapy. We present the case of a 61-year-old male patient diagnosed with localized MIBC 10 years ago. He underwent nerve-sparing radical cystectomy with ileal neobladder, but developed pulmonary metastatic disease 7 months postoperatively. Six cycles of gemcitabine/cisplatin combination chemotherapy with an addition of gefitinib as daily oral medication were administered within a randomized phase II clinical trial; this resulted in complete remission of the pulmonary metastases. Until now, the patient is still on gefitinib daily without any side effects. Although, the addition of gefitinib to standard systemic chemotherapy has not been shown to improve the survival in metastatic urothelial cancer, this case represents a very pleasant albeit uncommon long-term outcome. © 2016 S.

Urothelial carcinoma (UC) rarely metastasizes to the penis and skin. We report the case of a 73-year-old man with UC metastases to the corpus spongiosum and dermis of the distal penis. We also review the clinicopathologic characteristics and management options for UC metastasizing to the penis. The patient presented with priapism and edema of the genital region. This follows a 5-year history of urothelial carcinoma in situ that progressed to invasive cancer despite intravesical immunotherapy. Seventeen months prior to presentation, the patient underwent a radical cystectomy with adjuvant chemotherapy. The cystectomy specimen demonstrated a pT4a N2 M0 G3 UC and margins were positive for carcinoma in situ. Follow-up had been negative for recurrence until his presentation with priapism. Incisional biopsy of the glans revealed UC and radical penectomy was performed with negative margins. The penile specimen demonstrated extensive involvement of the corpus spongiosum by UC with lymphovascular invasion and subepidermal involvement. Three months after penectomy, the patient presented with inguinal nodal recurrence. Palliative radiotherapy was administered and the patient passed away eight months after surgery.

To determine the influence of the lunar phases and the position of the moon in the zodiac on the frequency of complications and the survival of bladder cancer patients after radical cystectomy. It has been postulated that radical cystectomy performed during the waxing moon, or particularly at full moon, or at the zodiac sign Libra is associated with a poorer outcome. We tested this hypothesis by evaluating the progression-free survival, the complication rate and the re-operation rate for 452 consecutive patients after radical cystectomy. In this retrospective review, the dates of surgery were allocated to the lunar phases and the zodiac signs. Based on these classifications, the patients were placed in groups which combined the lunar phase laws and differentiated between evidently unfavorable (full moon or waxing moon and/or the zodiac sign Libra; assigned to group 1) and favorable periods for surgery (new moon or waning moon and other signs of the zodiac apart from Libra; assigned to group 2). The mean follow-up was 49 months (range 0-158 months). A total of 244 patients (54%) were operated during an unfavorable period (group 1) and 208 (46%) patients during the auspicious period (group 2). The mean age, gender and kind of urinary derivation did not differ significantly in the two groups. Pathological tumor stages were evenly distributed according to the lunar phase groups (P = 0.713). We found no significant differences in the perioperative mortality rates, early re-operation rates, early complications, and late complications across the two groups. No significant differences in progression-free survival were observed when timing of cystectomy during the lunar cycle was considered (P = 0.231). Our analysis demonstrated no predictable influence of the lunar phase on survival or complications. Although this was not a prospective randomized trial, the statistical magnitude of the results do not support any recommendations for scheduling patients for radical cystectomy at any particular day of the lunar phase.

Purpose: Selective bladder preservation by use of trimodality therapy is an established management strategy for muscle-invasive bladder cancer. Individual disease features have been associated with response to therapy, likelihood of bladder preservation, and disease-free survival. We developed prognostic nomograms to predict the complete response rate, disease-specific survival, and likelihood of remaining free of recurrent bladder cancer or cystectomy. Methods and Materials: From 1986 to 2009, 325 patients were managed with selective bladder preservation at Massachusetts General Hospital (MGH) and had complete data adequate for nomogram development. Treatment consisted of a transurethral resection of bladder tumor followed by split-course chemoradiation. Patientsmore » with a complete response at midtreatment cystoscopic assessment completed radiation, whereas those with a lesser response underwent a prompt cystectomy. Prognostic nomograms were constructed predicting complete response (CR), disease-specific survival (DSS), and bladder-intact disease-free survival (BI-DFS). BI-DFS was defined as the absence of local invasive or regional recurrence, distant metastasis, bladder cancer-related death, or radical cystectomy. Results: The final nomograms included information on clinical T stage, presence of hydronephrosis, whether a visibly complete transurethral resection of bladder tumor was performed, age, sex, and tumor grade. The predictive accuracy of these nomograms was assessed. For complete response, the area under the receiving operating characteristic curve was 0.69. The Harrell concordance index was 0.61 for both DSS and BI-DFS. Conclusions: Our nomograms allow individualized estimates of complete response, DSS, and BI-DFS. They may assist patients and clinicians making important treatment decisions.« less

For radical cystectomy, historical practice trends have favored the use of preoperative bowel preparations to reduce complications, including surgical site infections, ileus, and anastomotic leaks. However, emerging data has questioned this practice. Postoperative cystectomy care also remains in flux, as new pharmacologic agents that may potentiate earlier return of bowel function are studied. We review the current literature with regards to preoperative and postoperative cystectomy bowel management.

Here, we report an inflammatory myofibroblastic tumor (IMT) of the urinary bladder with a novel HNRNPA1-ALK fusion. To the best of our knowledge, this is the first case of a tumor with HNRNPA1-ALK fusion. A 42-year-old Japanese man underwent total cystectomy because of an invasive urinary bladder tumor. Grossly, the tumor had invaded the peribladder fat tissue. Histologically, it comprised spindle neoplastic cells with intermingled inflammatory cells. Immunohistochemically, it was positive for ALK, SMA, desmin, cytokeratin, and vimentin, consistent with the immunohistochemical characteristics of IMTs. Fluorescence in situ hybridization demonstrated an ALK split, and the presence of HNRNPA1-ALK was revealed by RNA sequencing. We identified a novel transcript fusion of exon 2 of HNRNPA1 and exon 18 of ALK, resulting in ALK protein overexpression. These findings provide useful information on the biology and tumorigenesis of IMTs, thus facilitating the development of molecular-targeted therapeutics. Copyright © 2017 Elsevier Inc.

To assess systematically the quality of evidence for the volume-outcome relationship in uro-oncology, and thus facilitate the formulating of health policy within this speciality, as 'Implementation of Improving Outcome Guidance' has led to centralization of uro-oncology based on published studies that have supported a 'higher volume-better outcome' relationship, but improved awareness of methodological drawbacks in health service research has questioned the strength of this proposed volume-outcome relationship. We systematically searched previous relevant reports and extracted all articles from 1980 onwards assessing the volume-outcome relationship for cystectomy, prostatectomy and nephrectomy at the institution and/or surgeon level. Studies were assessed for their methodological quality using a previously validated rating system. Where possible, meta-analytical methods were used to calculate overall differences in outcome measures between low and high volume healthcare providers. In all, 22 studies were included in the final analysis; 19 of these were published in the last 5 years. Only four studies appropriately explored the effect of both the institution and surgeon volume on outcome measures. Mortality and length of stay were the most frequently measured outcomes. The median total quality scores within each of the operation types were 8.5, 9 and 8 for cystectomy, prostatectomy and nephrectomy, respectively (possible maximum score 18). Random-effects modelling showed a higher risk of mortality in low-volume institutions than in higher-volume institutions for both cystectomy and nephrectomy (odds ratio 1.88, 95% confidence interval 1.54-2.29, and 1.28, 1.10-1.49, respectively). The methodological quality of volume-outcome research as applied to cystectomy, prostatectomy and nephrectomy is only modest at best. Accepting several limitations, pooled analysis confirms a higher-volume, lower-mortality relationship for cystectomy and nephrectomy. Future research should focus on the development of a quality framework with a validated scoring system for the bench-marking of data to improve validity and facilitate rational policy-making within the speciality of uro-oncology.

To describe the initial feasibility of fluorescence-enhanced robotic radical cystectomy (FERRC) using real-time cystoscopic injection of unconjugated indocyanine green (ICG) for tumor marking and identification of sentinel lymphatic drainage with additional intravenous injection for mesenteric angiography. Ten patients with clinically localized high-grade bladder cancer underwent FERRC. Before robot docking, rigid cystoscopy was performed, during which a 2.5-mg/mL ICG solution was injected in the bladder submucosa and detrusor circumferentially around the tumor. After robot docking, parameters describing the time course of tissue fluorescence and pelvic lymphangiography were systematically recorded. Lymphatic packets containing fluorescent lymph nodes were considered the sentinel drainage. Eight patients underwent intracorporeal ileal conduit urinary diversion, during which an additional 2-mL ICG solution was given intravenously for mesenteric angiography, allowing maximal preservation of bowel vascularity to the conduit and remaining bowel segments. Bladder tumor marking and identification of sentinel drainage were achieved in 9 of 10 (90%) patients. The area of bladder tumor was identified at a median of 15 minutes after injection, whereas sentinel drainage was visualized at a median of 30 minutes. Mesenteric angiography was successful in 8 of 8 (100%) patients at a median time of <1 minutes after intravenous injection and enabled identification of bowel arcades before intracorporeal bowel stapling. FERRC using combined cystoscopic and intravenous injection of ICG is safe and feasible. FERRC allows for reliable bladder tumor marking, identification of sentinel lymphatic drainage, and identification of mesenteric vasculature in most patients. Copyright © 2014 Elsevier Inc.

Women undergoing radical cystectomy (RC) and urinary diversion for bladder cancer experience substantial limitations in health-related quality of life (HRQOL). However, the level of discomfort caused by different urinary diversion has been never evaluated in long term survivors. The aim of this multicenter study is to evaluate differences in HRQOL among recurrence-free women undergoing cutaneous ureterostomy (CUS), Bricker's ileal conduit (BK-IC) and Orthotopic neobladder VIP (ONB-VIP) in disease-free females treated with radical cystectomy (RC), with long-term follow up (mean 60.1 months; range 36-122 months). All consecutively treated female patients from two urological institutions who underwent RC and urinary diversion from January 2000 to December 2008, with no evidence of tumor recurrence at a minimum follow up of 36 months, were included. Patients received the European Organisation for Research and Treatment of Cancer (EORTC) generic (QLQ-C30) and bladder cancer-specific instruments (QLQ-BLM30) and the Functional Assessment of Cancer Therapy for Bladder Cancer (FACT-BL). Clinical data and questionnaire results were analyzed in order to evaluate the HRQOL differences among diversion groups. We identified 37 females (median age: 68, range 45-82 years), including 12 status-post CUS, 16 who underwent BK-IC, and 9 who underwent ONB-VIP. Most were healthy (24/37 with no comorbidities, 4/37 Charlson 1-2, 9/37 Charlson 3 or greater - we didn't considered bladder cancer in Charlson evaluation because bladder cancer was the main inclusion criteria). Women undergoing CUS endorsed worse FACT-BL scores compared with BK-IC and ONB-VIP patients, worse HRQOL regarding physical and emotional well-being (p=0.008 and p=0.02, respectively), and a trend toward worse EORTC QLQ-C30 scores for appetite loss and fatigue (p=0.05 for both). In our study long-term disease-free females treated with CUS endorsed worse HRQOL compared with women who underwent BK-IC or ONB-VIP, mostly due to worse physical and emotional perception of their body image.

Urinary tract infection (UTI) is one of the most common complications after radical cystectomy and orthotopic neobladder reconstruction. This study investigated the incidence and implicated pathogen of febrile UTI after ileal neobladder reconstruction and identify clinical and urodynamic parameters associated with febrile UTI. From January 2001 to May 2015, 236 patients who underwent radical cystectomy and ileal neobladder were included in this study. Fifty-five episodes of febrile UTI were identified in 46 patients (19.4%). The probability of febrile UTI was 17.6% and 19.8% at 6 months and 24 months after surgery, respectively. While, Escherichia coli was the most common implicated pathogen (22/55, 40.0%), Enterococcus spp. were the most common pathogen during the first month after surgery (18/33, 54.5%). In multivariate logistic regression analysis, ureteral stricture was an independent risk factor associated with febrile UTI (OR 5.93, P = 0.023). However, ureteral stricture accounted for only 6 episodes (10.9%, 6/55) of febrile UTI. Most episodes of febrile UTI occurred within 6 months after surgery. Thus, to identify risk factors associated with febrile UTI in the initial postoperative period, we assessed videourodynamics within 6 months after surgery in 38 patients. On videourodyamic examination, vesicoureteral reflux (VUR) was identified in 16 patients (42.1%). The rate of VUR presence in patients who had febrile UTI was not significantly different from those in patients without febrile UTI (50% vs. 39.3%, P = 0.556). Patients with febrile UTI had significantly larger residual urine volume (212.0 ± 193.7 vs. 90.5 ± 148.2, P = 0.048) than those without. E. coli and Enterococcus spp. are common pathogens and ureteral stricture and residual urine are risk factors for UTI after ileal neobladder reconstruction.

Long-term oncologic outcomes following robot-assisted radical cystectomy (RARC) remain scarce. To report long-term oncologic outcomes following RARC at a single institution. Retrospective review of 99 patients who underwent RARC for urothelial carcinoma of bladder between 2005 and 2009. RARC was performed. Primary outcomes included recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS), measured by the Kaplan-Meier method. The association between primary outcomes and perioperative and pathologic factors was assessed using a multivariable Cox proportional hazards model. Fifty-one (52%) patients had stage pT3 or higher disease. Eight (8%) patients had positive margins and 30 (30%) had positive lymph nodes (LNs), with a median of 21 LNs removed. Median follow-up for patients alive was 74 mo. The 5-yr RFS, CSS, and OS rates were 52.5%, 67.8%, and 42.4%, respectively. Tumor stage, LN stage, and margin status were each significantly associated with RFS, CSS, and OS. On multivariable analysis, tumor and LN stage were independent predictors of RFS, CSS, and OS, while positive margin status and Charlson comorbidity index predicted worse OS and CSS. Adjuvant chemotherapy predicted RFS only. Retrospective design and lack of open comparison are main limitations of this study. Long-term oncologic outcomes following RARC demonstrate RFS and CSS estimates similar to those reported in literature for open radical cystectomy. Randomized controlled trials can better define outcomes of any alternative technique. Survival data 5 yr after RARC for bladder cancer demonstrate that survival outcomes are dependent on the same oncologic parameters as previously reported for open surgery.

Objective To evaluate the risk of different in-hospital complications for patients undergoing a radical cystectomy (RC), as limited nationwide population data on short- and long-term complications after RC is available, despite it being the standard treatment for localised muscle-invasive urinary bladder cancer (UBC). Patients and Methods In all, 7608 persons underwent a RC after UBC diagnosis, as registered in the Swedish National Patient Register between 1964 and 2008. We estimated the frequency and incidences and calculated hazard ratios (HR) and 95% confidence intervals (CI) using multivariate Cox proportional hazards models. Results Urinary tract infection/septicaemia was the most common complication following radical cystectomy, with an incidence of 90.4 per 1,000 person years. There was a higher risk of urinary tract infection among patients who had a continent cutaneous reservoir (HR: 1.11 (0.94–1.30) or orthotopic neobladder 1.21 (1.05–1.39) than among those with ileal conduit. Similarly, continent cutaneous reservoir and orthotopic neobladder were associated with increased risks for wound and abdominal wall hernias, stones in the urinary tract, hydronephrosis and nephrostomy tube treatment, and kidney failure. In contrast, risk of bowel obstruction was lower among those with orthotopic neobladder than those with ileal conduit (HR: 0.64 (0.50–0.81)) and those with continent cutaneous reservoir (HR: 0.92 (0.73–1.16). Conclusions In-hospital complications after RC are numerous and continue to accumulate for many years after surgery, indicating the need for life-long follow-up of these patients. Comparison between different types of diversion should, however, be made with care because of potential confounding by indication. PMID:23906011

Squamous cell carcinoma (SCC) is an uncommon histologic subtype of bladder cancer with limited data on treatment patterns, outcomes, and prognostic factors. "Real world" information might inform decision-making, prognostic estimates, and clinical trial designs. A retrospective review of patients with tissue-confirmed bladder SCC treated at Cleveland Clinic from 2007 to 2016 was performed. Data on patient characteristics, treatment patterns, and clinical follow-up were extracted. Univariate analysis was used to identify predictors of overall survival (OS), recurrence-free survival (RFS) and time to recurrence. Of 58 identified patients, 42 had complete data available. Median age at diagnosis was 67 years (range, 37-90). Hematuria was the most common (71%) presenting symptom; 32 patients had pure SCC and 10 predominant/extensive squamous differentiation without major differences noted in clinicopathologic variables or outcomes among those 2 groups. Overall, 35 patients underwent cystectomy with 5 receiving neoadjuvant and 1 adjuvant chemotherapy, whereas 3 had chemotherapy for recurrent disease. Of patients with cystectomy, most had locally advanced disease (75% pT3/4, 35% pN+). Overall, 10 patients progressed and 14 died; median OS was not reached. The 2-year estimated OS, RFS, and cumulative incidence of recurrence were 61% ± 9%, 50% ± 9%, and 32% ± 9%, respectively. Hydronephrosis, older age (70 years or older), lymphovascular invasion, nodal metastases, and advanced T stage were associated with 1 or more poor outcomes. In patients with resectable bladder SCC, radical cystectomy remains the main treatment modality. The role of perioperative chemotherapy remains unclear. The identified prognostic factors might be helpful for prognostication, treatment discussion, and trial eligibility/stratification. Copyright © 2017 Elsevier Inc. All rights reserved.

The aim of this study was to find the unfavorable prognostic factors for recurrence after fertility-preserving surgery (FPS) in patients with borderline ovarian tumors (BOTs). To perform a meta-analysis to compare the recurrence rates of BOT patients after FPS according to different prognostic factors, we searched PubMed, EMBASE, and Cochrane for observational studies. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated with a fixed-effects model. We analyzed 32 studies that included 2691 BOT patients who underwent FPS, 383 patients of whom had a relapse in the follow-up. In meta-analysis, risks associated with recurrence in patients with unilateral cystectomy (OR, 2.49; 95% CI, 1.86-3.33) or serous borderline ovarian tumors (OR, 3.15; 95% CI, 1.97-5.02) were significantly increased, and there was no significantly increased OR for patients with laparoscopy compared with those with laparotomy (OR, 0.96; 95% CI, 0.57-1.60). Unilateral cystectomy (19.4%) and serous BOTs (19.2%) are significantly associated with higher recurrence rates, and no negative impact of laparoscopy on recurrence can be demonstrated when compared with laparotomy in the meta-analysis.

Neoadjuvant chemotherapy before cystectomy is recommended. To our knowledge the subset of patients likely to benefit has not been identified. We validate emmprin and survivin as markers of chemotherapy response. Tumor specimens were obtained before therapy from a total of 250 patients with T1-T4 bladder cancer enrolled in 2 randomized trials comparing neoadjuvant chemotherapy before cystectomy with a surgery only arm. Protein expression was determined by immunohistochemistry. Expression was categorized according to predefined cutoffs reported in the literature. Data were analyzed with the Kaplan-Meier method and Cox models. Patients in the chemotherapy cohort with negative emmprin expression had significantly higher down staging overall survival than those with positive expression (71% vs 38%, p<0.001). The values for cancer specific survival were 76% and 56%, respectively (p<0.027). In the cystectomy only cohort emmprin expression was not associated with overall survival (46% vs 35%, p=0.23) or cancer specific survival (55% vs 51%, p=0.64). Emmprin negative patients had an absolute risk reduction of 25% in overall survival (95% CI 11-40) and a number needed to treat of 4 (95% CI 2.5-9.3). Survivin expression was not useful as a biomarker in this study. Limitations were the retrospective design and heterogeneity coupled with the time difference between the trials. Patients with emmprin negative tumors have a better response to neoadjuvant chemotherapy before cystectomy than those with positive expression.

Radical cystectomy is the gold-standard treatment for muscle-invasive and refractory nonmuscle-invasive bladder cancer. We describe our technique for robotic radical cystectomy (RRC) and intracorporeal urinary diversion (ICUD), that replicates open surgical principles, and present our preliminary results. Specific descriptions for preoperative planning, surgical technique, and postoperative care are provided. Demographics, perioperative and 30-day complications data were collected prospectively and retrospectively analyzed. Learning curve trends were analyzed individually for ileal conduits (IC) and neobladders (NB). SAS(®) Software Version 9.3 was used for statistical analyses with statistical significance set at P < 0.05. Between July 2010 and September 2013, RRC and lymph node dissection with ICUD were performed in 103 consecutive patients (orthotopic NB=46, IC 57). All procedures were completed robotically replicating the open surgical principles. The learning curve trends showed a significant reduction in hospital stay for both IC (11 vs. 6-day, P < 0.01) and orthotopic NB (13 vs. 7.5-day, P < 0.01) when comparing the first third of the cohort with the rest of the group. Overall median (range) operative time and estimated blood loss was 7 h (4.8-13) and 200 mL (50-1200), respectively. Within 30-day postoperatively, complications occurred in 61 (59%) patients, with the majority being low grade (n = 43), and no patient died. Median (range) nodes yield was 36 (0-106) and 4 (3.9%) specimens had positive surgical margins. Robotic radical cystectomy with totally ICUD is safe and feasible. It can be performed using the established open surgical principles with encouraging perioperative outcomes.

Introduction Urothelial cell carcinoma is the most common neoplasm of the genito-urinary tract, which, in advanced stages, is treated with radical cystectomy with pelvic lymphadenectomy. It can be performed by an open or minimally invasive approach (laparoscopic and robot-assisted radical cystectomy). Large meta-analyses showed a significantly lower complication rate in the RARC (robot-assisted radical cystectomy) group compared to ORC (open radical cystectomy) in thirty and ninety days after surgery, with similar oncological and functional outcomes. The clinical outcomes of the first forty Polish RARC are explored in this article. Material and methods The Polish Radical Robotic Cystectomy Program (PRRC) was started in 2016 at the Nicolaus Copernicus Hospital in Toruń. Forty consecutive patients, with indications for cystectomy were included into the study. During radical robot-assisted cystectomy, obturator, external, internal, common iliac and presacral lymph nodes were dissected. Oncological outcomes, early complication rate, and the clinical variables were analyzed. Results The mean age in the study group was sixty-seven years, with the majority of patients being overweight and assessed as American Society of Anesthesiology Scale (ASA) – ASA III and ASA IV (2/3 of patients). RARC was performed, with the median time of surgery being 324 minutes (170 minutes being the shortest). Mean blood loss was 365 ml (lowest – 50 ml), and only 2 patients required intraoperative blood transfusion. Twenty patients had ileal conduit, and nineteen had other methods of urinary diversion. Only twenty-nine out of forty patients had minor complications (Clavien I and II), 11 had Clavien III and IV. Clavien V was not present. Only 3 patients required reoperation. Conclusions RARC is a reproducible oncological procedure, which can be safely performed in centers with robotic expertise, with acceptable operative time, complications, and functional and oncologic outcomes.

Comprehensive and standardized reporting of adverse events after robot-assisted radical cystectomy (RARC) and urinary diversion for bladder cancer is necessary to evaluate the magnitude of morbidity for this complex operation. To accurately identify and assess postoperative morbidity after RARC using a standardized reporting system. A total of 241 consecutive patients underwent RARC, extended pelvic lymph node dissection, and urinary diversion between 2003 and 2011. In all, 196 patients consented to a prospective database, and they are the subject of this report. Continent diversions were performed in 68% of cases. All complications within 90 d of surgery were defined and categorized by a five-grade and 10-domain modification of the Clavien system. Univariable and multivariable logistic regression analyses were used to identify predictors of complications. Grade 1-2 complications were categorized as minor, and grade 3-5 complications were categorized as major. All blood transfusions were recorded as grade ≥2. Eighty percent of patients (156 of 196 patients) experienced a complication of any grade ≤90 d after surgery. A total of 475 adverse events (113 major) were recorded, with 365 adverse events (77%) occurring ≤30 d after surgery. Sixty-eight patients (35%) experienced a major complication within the first 90 d. Other than blood transfusions given (86 patients [43.9%]), infectious, gastrointestinal, and procedural complications were the most common, at 16.2%, 14.1%, and 10.3%, respectively. Age, comorbidity, preoperative hematocrit, estimated blood loss, and length of surgery were predictive of a complication of any grade, while comorbidity, preoperative hematocrit, and orthotopic diversion were predictive of major complications. The 90-d mortality rate was 4.1%. The main limitation is lack of a control group. Analysis of postoperative morbidity following RARC demonstrates a considerable complication rate, though the rate is comparable to contemporary open series that followed similar reporting guidelines. This finding reinforces the need for complete and standardized reporting when evaluating surgical techniques and comparing published series. Copyright © 2012 European Association of Urology.

Radical cystectomy (RC) is an effective but underused treatment for bladder cancer in elderly patients. This study performed analysis of propensity scores (PSs) to determine the outcomes of RC for elderly patients, with results generalizable at the population-based level. We conducted a population-based, retrospective cohort study of patients who underwent RC in Taiwan during 2000-2010. Multivariable logistic regression was implemented to evaluate 30- and 90-day mortality and readmission rates, length of intensive care unit (ICU) stay, length of hospital stay (LOS), and cost. Enrolled patients were divided into younger (≤75 years) and older groups (>75 years) who were matched according to their PSs. We identified 430 patients with bladder cancer who underwent RC between 2000 and 2010. Older age was not significantly associated with 30-day readmission (odds ratio [OR] = 0.80, 95% confidence interval [CI] = 0.38-1.70), 90-day readmission (OR = 1.10, 95% CI = 0.60-2.00), 30-day mortality (OR = 3.07, 95% CI = 0.31-30.0), or 90-day mortality (OR = 2.98, 95% CI = 0.91-9.70) in the PS-matched group. Similar trends were also observed for both groups regarding the mean length of ICU stay, LOS, and overall medical expenditure within the same admission. No significant differences existed between the older and younger groups for 30-and 90-day mortality and readmission rates, length of ICU stay, LOS, and medical expenditure in patients undergoing RC for bladder cancer. Some healthy elderly patients may be good candidates for this extensive curative treatment.

Purpose: To evaluate the predictive accuracy and general applicability of the locoregional failure model in a different cohort of patients treated with radical cystectomy. Methods and Materials: A total of 398 patients were included in the analysis. Death and isolated distant metastasis were considered competing events, and patients without any events were censored at the time of last follow-up. The model included the 3 variables pT classification, the number of lymph nodes identified, and margin status, as follows: low risk (≤pT2), intermediate risk (≥pT3 with ≥10 nodes removed and negative margins), and high risk (≥pT3 with <10 nodes removed ormore » positive margins). Results: The bootstrap-corrected concordance index of the model 5 years after radical cystectomy was 66.2%. When the risk stratification was applied to the validation cohort, the 5-year locoregional failure estimates were 8.3%, 21.2%, and 46.3% for the low-risk, intermediate-risk, and high-risk groups, respectively. The risk of locoregional failure differed significantly between the low-risk and intermediate-risk groups (subhazard ratio [SHR], 2.63; 95% confidence interval [CI], 1.35-5.11; P<.001) and between the low-risk and high-risk groups (SHR, 4.28; 95% CI, 2.17-8.45; P<.001). Although decision curves were appropriately affected by the incidence of the competing risk, decisions about the value of the models are not likely to be affected because the model remains of value over a wide range of threshold probabilities. Conclusions: The model is not completely accurate, but it demonstrates a modest level of discrimination, adequate calibration, and meaningful net benefit gain for prediction of locoregional failure after radical cystectomy.« less

Radical cystectomy for bladder cancer is associated with a high risk of needing red blood cell transfusion. Tranexamic acid reduces blood loss during cardiac and orthopedic surgery, but no study has yet evaluated tranexamic acid use during cystectomy. A randomized, double-blind (surgeon-, anesthesiologist-, patient-, data-monitor-blinded), placebo-controlled trial of tranexamic acid during cystectomy was initiated in June 2013. Prior to incision, the intervention arm participants receive a 10 mg/kg loading dose of intravenously administered tranexamic acid, followed by a 5 mg/kg/h maintenance infusion. In the control arm, the patient receives an identical volume of normal saline that is indistinguishable from the intervention. The primary outcome is any blood transfusion from the start of surgery up to 30 days post operative. There are no strict criteria to mandate the transfusion of blood products. The decision to transfuse is entirely at the discretion of the treating physicians who are blinded to patient allocation. Physicians are allowed to utilize all resources to make transfusion decisions, including serum hemoglobin concentration and vital signs. To date, 147 patients of a planned 354 have been randomized to the study. This protocol reviews pertinent data relating to blood transfusion during radical cystectomy, highlighting the need to identify methods for reducing blood loss and preventing transfusion in patients receiving radical cystectomy. It explains the clinical rationale for using tranexamic acid to reduce blood loss during cystectomy, and outlines the study methods of our ongoing randomized controlled trial.

Robotic-assisted laparoscopic radical cystectomy: history, techniques and outcomes.

PubMed

Liss, Michael A; Kader, A Karim

Robotic-assisted radical cystectomy (RARC) is a less invasive means of performing the radical cystectomy operation, which holds promise for improved patient morbidity. We review the history, technique and current literature pertaining to RARC and place the current results in context with the open procedure. All articles regarding RARC found in PubMed after January 2000 were examined. We selected articles that appeared in high-impact journals, had large patient population size (>80 patients), or were novel in technique or findings. We chose key laparoscopic articles to give reference to the history in transition to robotic radical cystectomy. In addition, we chose classic articles from open radical cystectomy to give reference regarding the newer robotic perioperative outcomes. Studies suggest that a 20-patient learning curve is needed to reach an operative time of 6.5 h, with 30 surgeries performed to reach lymph node counts in excess of 20 (International Robotic Cystectomy Consortium). The only randomized surgical trial comparing open and robotic techniques showed equivalent lymph node yield, which may be surgeon and volume dependent. Literature demonstrates lower estimated blood loss, transfusion rates, early return of bowel function and decreased complications in early small series. RARC and urinary diversion are still early in development and limited to centers with extensive robotic experience and volume, although adoption of the robotic approach is becoming more common. Early studies have shown promise to reduce complications with equivalent oncologic results.

Serum total human chorionic gonadotrophin β subunit (hCGβ) level might have prognostic value in urothelial transitional cell carcinoma (TCC) but has not been investigated for independence from other prognostic variables. We utilised a clinical database of patients receiving chemotherapy between 2005 and 2011 for urothelial TCC and an independent cohort of radical cystectomy patients for validation purposes. Prognostic variables were tested by univariate Kaplan-Meier analyses and log-rank tests. Statistically significant variables were then assessed by multivariate Cox regression. Total hCGβ level was dichotomised at < vs ≥2 IU l(-1). A total of 235 chemotherapy patients were eligible. For neoadjuvant chemotherapy, established prognostic factors including low ECOG performance status, normal haemoglobin, lower T stage and suitability for cisplatin-based chemotherapy were associated with favourable survival in univariate analyses. In addition, low hCGβ level was favourable when assessed either before (median survival not reached vs 1.86 years, P=0.001) or on completion of chemotherapy (4.27 vs 0.42 years, P=0.000002). This was confirmed in multivariate analyses and in patients receiving first- and second-line palliative chemotherapy, and in a radical cystectomy validation set. Serum total hCGβ level is an independent prognostic factor in patients receiving chemotherapy for urothelial TCC in both curative and palliative settings.

Radical cystectomy and regional lymph node dissection is the standard treatment for localized muscle-invasive and for high-risk non-muscle-invasive bladder cancer, and represents one of the main surgical urologic procedures. The open surgical approach is still widely adopted, even if in the last two decades efforts have been made in order to evaluate if minimally invasive procedures, either laparoscopic or robot-assisted, might show a benefit compared to the standard technique. Open radical cystectomy is associated with a high complication rate, but data from the laparoscopic and robotic surgical series failed to demonstrate a clear reduction in post-operative complication rates compared to the open surgical series. Laparoscopic and robotic radical cystectomy show a reduction in blood loss, in-hospital stay and transfusion rates but a longer operative time, while open radical cystectomy is typically associated with a shorter operative time but with a longer in-hospital admission and possibly a higher rate of high grade complications.

To evaluate the factors influencing the operative duration of ovarian cystectomy by single-port access (SPA). Observational monocentric study from June 2010 to September 2012. Inclusive patients were patients with an indication of ovarian cystectomy may be done by laparoscopy. The procedures were performed by the SPA system LESS®. Factors evaluated were BMI of the patient, histological nature and size of the cyst. We performed 54 cystectomy in 49 patients. SPA surgery was successfully completed in 53 patients. The median operative time was statistically longer for endometriotic cysts than dermoid cysts or serous-mucinous cysts (P=0.003). Cases exceeding 60minutes were significantly higher in the endometriosis group (P=0.005). There wasn't correlation found between the BMI of the patient and operative time (P=0.5). The operating time wasn't increased according to the size of the cyst (P=0.9). Endometriotic cysts nature appears to be the only limiting factor of cystectomy by SPA. Further studies are needed to evaluate the factors that may limit the SPA actions. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

Purpose To report our technique for and experience with robot-assisted laparoscopic radical cystectomy (RARC) with orthotopic neobladder (ON) formation in a cohort of bladder cancer patients. Materials and Methods Between December 2007 and December 2011, a total of 35 patients underwent RARC. The patients' mean age was 63.3 years and their mean body mass index was 23.7 kg/m2. Thirty patients had a clinical stage of T2 or higher. Postoperative mean follow-up duration was 25.5 months. In 5 patients, a 4-cm midline infraumbilical skin incision was made for an ileal conduit (IC) and the stoma formation was similar to the open procedure. In 30 patients undergoing the ON procedure, the skin for specimen removal and extracorporeal enterocystoplasty was incised infraumbilically in the early 5 cases with redocking (ON-I) and suprapubically in the latter 25 cases without redocking (ON-S). Results The mean operative times of the IC, ON-I, and ON-S groups were 442.5, 646.0, and 531.3 minutes, respectively (p=0.001). Mean console and lymph node dissection time were not significantly different between the groups. Mean urinary diversion times in each group were 68.8, 125.0, and 118.8 minutes, respectively (p=0.001). In the comparison between the ON-I and ON-S group, only operative time was significant. Four patients required a blood transfusion. We had no cases of intraabdominal organ injury or open conversion. Thiry-three patients (94.2%) had a pathologic stage of T2 or higher. Two patients (5.7%) had lymph node-positive disease. Postoperative complications included ileus (n=4), stricture in the uretero-ileal junction (n=2), and vesicovaginal fistula (n=1). Conclusions Our robotic neobladder-suprapubic incision without redocking procedure is easier and more rapid than that of infraumbilical incision with redocking. PMID:23185668

Purpose/Objective(s): To review our experience with bladder-preserving trimodality treatment (TMT) using hypofractionated intensity modulated radiation therapy (IMRT) for the treatment of elderly patients with muscle-invasive bladder cancer. Methods and Materials: Retrospective study of elderly patients treated with TMT using hypofractionated IMRT (50 Gy in 20 fractions) with concomitant weekly radiosensitizing chemotherapy. Eligibility criteria were as follows: age ≥70 years, a proven diagnosis of muscle-invasive transitional cell bladder carcinoma, stage T2-T3N0M0 disease, and receipt of TMT with curative intent. Response rate was assessed by cystoscopic evaluation and bladder biopsy. Results: 24 patients with a median age of 79 years were eligible.more » A complete response was confirmed in 83% of the patients. Of the remaining patients, 1 of them underwent salvage cystectomy, and no disease was found in the bladder on histopathologic assessment. After a median follow-up time of 28 months, of the patients with a complete response, 2 patients had muscle-invasive recurrence, 1 experienced locoregional failure, and 3 experienced distant metastasis. The overall and cancer-specific survival rates at 3 years were 61% and 71%, respectively. Of the surviving patients, 75% have a disease-free and functioning bladder. All patients completed hypofractionated IMRT, and 19 patients tolerated all 4 cycles of chemotherapy. Acute grade 3 gastrointestinal or genitourinary toxicities occurred in only 4% of the patients, and acute grade 3 or 4 hematologic toxicities, liver toxicities, or both were experienced by 17% of the cohort. No patient experienced grade 4 gastrointestinal or genitourinary toxicity. Conclusions: Hypofractionated IMRT with concurrent radiosensitizing chemotherapy appears to be an effective and well-tolerated curative treatment strategy in the elderly population and should be considered for patients who are not candidates for cystectomy or who wish to avoid cystectomy.« less

To explore the effects of conservative surgery for endometriomas on ovarian responsiveness during assisted reproductive technology (ART) and provide reproductive and gynecological doctors with a more reliable reference program for the treatment of endometriomas. A literature search was performed by searching the PubMed, Embase, Cochrane Library, Web of Science and Science Direct databases. Studies with inter- and intra-patient comparisons of ovarian responses and oocyte quality between operated and unoperated ovaries and that met the inclusion criteria were retrieved, and the data from the outcome measures were extracted and pooled for this meta-analysis. Twenty-one published studies (2649 ART cycles) were included. The total amount of gonadotropin (Gn) used (inverse variance (IV):0.48; 95% confidence interval (CI): [0.13, 1.82], P = 0.0007) was significantly increased in the women with endometriomas who had a history of cystectomy. The estrogen (E) level on the day of hCG administration (IV: -0.29; 95% CI: [-0.41, -0.17], P<0.00001), the number of mature or dominant follicles (IV: -1.17; 95% CI: [-1.51, -0.82], P<0.00001) and the total number of oocytes retrieved (IV: -1.78; 95% CI: [-2.38, -1.17], P<0.00001) were significantly decreased in the women with endometriomas who had a history of cystectomy. The duration of stimulation (IV: 0.02; 95% CI: [-0.09, 0.13], P = 0.77), the total number of formed embryos (IV: -0.06; 95% CI: [-0.17, 0.04], P = 0.25), the pregnancy rate(IV:0.98;95%CI[0.82,1.18], P = 0.83) and the live birth rate(IV:0.93;95%CI[0.70,1.23], P = 0.61)were not statistically different between the two groups. Similar intra-patient results were found in the number of mature or dominant follicles (IV: -0.88; 95% CI: [-1.25, -0.52], P<0.00001) and the total number of oocytes retrieved (IV: -3.48; 95% CI: [-4.77, -2.19], P<0.00001). ART might be a better therapeutic method for ovarian endometrioma-related infertility than cystectomy.

We hypothesized that in patients with T2N0 stage disease at transurethral bladder tumor resection a lower residual cancer stage (P1N0 or less) at radical cystectomy may correlate with improved outcomes relative to those with residual P2N0 disease. We analyzed 208 patients with T2N0 stage disease at transurethral bladder tumor resection whose tumors were organ confined at radical cystectomy (P2 or lower, pN0). None received perioperative chemotherapy. Kaplan-Meier as well as univariable and multivariable Cox regression models addressed the effect of residual pT stage at radical cystectomy on recurrence and cancer specific mortality rates. Covariates consisted of age, gender, grade, lymphovascular invasion, carcinoma in situ, number of lymph nodes removed and year of surgery. Residual pT stage at radical cystectomy was P0 in 24 (11.5%) patients, Pa in 9 (4.3%), PCIS in 22 (10.6%), P1 in 35 (16.8%) and P2 in 118 (56.7%). Median followup of censored patients was 55.7 months for recurrence and 52.1 months for cancer specific mortality analyses. The 5-year recurrence-free survival rates of patients with P0/Pa/PCIS, P1 and P2 stage disease were 100%, 85% and 75%, respectively. The 5-year cancer specific survival rates for the same cohorts were 100%, 93% and 81%, respectively. On multivariable analysis the effect of residual stage P1 or lower at radical cystectomy achieved independent predictor status for recurrence (adjusted HR 0.20, p = 0.002) and cancer specific mortality (adjusted HR 0.24, p = 0.02). Down staging from initial T2N0 bladder cancer at transurethral bladder tumor resection to lower stage at radical cystectomy significantly reduces recurrence and cancer specific mortality. Further validation of this finding is warranted.

Objective To measure the association between a surgeon’s degree of specialization in a specific procedure and patient mortality. Design Retrospective analysis of Medicare data. Setting US patients aged 66 or older enrolled in traditional fee for service Medicare. Participants 25 152 US surgeons who performed one of eight procedures (carotid endarterectomy, coronary artery bypass grafting, valve replacement, abdominal aortic aneurysm repair, lung resection, cystectomy, pancreatic resection, or esophagectomy) on 695 987 patients in 2008-13. Main outcome measure Relative risk reduction in risk adjusted and volume adjusted 30 day operative mortality between surgeons in the bottom quarter and top quarter of surgeon specialization (defined as the number of times the surgeon performed the specific procedure divided by his/her total operative volume across all procedures). Results For all four cardiovascular procedures and two out of four cancer resections, a surgeon’s degree of specialization was a significant predictor of operative mortality independent of the number of times he or she performed that procedure: carotid endarterectomy (relative risk reduction between bottom and top quarter of surgeons 28%, 95% confidence interval 0% to 48%); coronary artery bypass grafting (15%, 4% to 25%); valve replacement (46%, 37% to 53%); abdominal aortic aneurysm repair (42%, 29% to 53%); lung resection (28%, 5% to 46%); and cystectomy (41%, 8% to 63%). In five procedures (carotid endarterectomy, valve replacement, lung resection, cystectomy, and esophagectomy), the relative risk reduction from surgeon specialization was greater than that from surgeon volume for that specific procedure. Furthermore, surgeon specialization accounted for 9% (coronary artery bypass grafting) to 100% (cystectomy) of the relative risk reduction otherwise attributable to volume in that specific procedure. Conclusion For several common procedures, surgeon specialization was an important predictor of operative mortality independent of volume in that specific procedure. When selecting a surgeon, patients, referring physicians, and administrators assigning operative workload may want to consider a surgeon’s procedure specific volume as well as the degree to which a surgeon specializes in that procedure.

Primary localized bladder amyloidosis is a rare pathology that mimics urothelial cancer. Systemic disease and lymphoproliferative disorders should be excluded. Transurethral resection is the mainstay of treatment, although in cases of extensive bladder involvement or massive haematuria radical cystectomy has been reported. To the authors' knowledge, this is the first robot-assisted prostate-sparing simple cystectomy with intracorporeal neobladder and preservation of the seminal vesicles and vas deferens reported in the literature, in a patient with primary localized amyloidosis of the bladder.

An increasing number of adnexal masses are currently managed laparoscopically, which has hampered progress regarding the different techniques of laparoscopic surgery. In this chapter, a modified application of surgical instrument was described in laparoscopic ovarian cystectomy-we named this device, Lap-Disc Mini. This new instrument has three rings, an inner flexible ring fixed to a middle ring by a rubber corset, and an additional dynamic outer ring that has a rubbery-like iris opening, which allows the application of different-sized trocars and extracorporeal ovarian cystectomy. This technique has proved to be effective and safe, especially in removing large ovarian cyst.

Objective To compare the long term impact on ovarian reserve between laparoscopic ovarian cystectomy with bipolar electrocoagulation and laparotomic cystectomy with suturing for ovarian endometrotic cyst. Patient and method(s) 121 patients with benign ovarian endometroitic cysts were randomised to either laparoscopic ovarian cystectomy using bipolar electrocoagulation (61 patients) or laparotomic ovarian cystectomy using sutures (60 patients). Serum follicle-stimulating hormone, Antimullerian hormon, Basal antral follicle Count, mean ovarian diameter, and ovarian stromal blood flow velocity were measured at 6, 12 and 18 months after surgery and compared in both groups. Result(s) A statistically significant increase of serum FSH was found in the laproscopic bipolar group at 6-, 12 and 18-month postoperativly compared to open laparotomy suture group. Also, a statistically significant decrease of the mean AMH value occurred in laproscopic bipolar group at 6-, 12 and 18-month follow- up compared to open laparotomy suture group. Basal antral follicle number, mean ovarian diameter and peak systolic velocity were significantly decreased during the 6-, 12,18 -month follow-up in laproscopic bipolar group compared to open laparotomy suture group. Conclusion(s) After laproscopic ovarian cystecomy for endometrioma all pareameter of ovarian reseve are significantly decreased on long term follow up as compared to open laprotomy. PMID:24180348

Extended lymphadenectomy in bladder cancer.

Radical cystectomy with pelvic lymph node dissection (PLND) is the preferred treatment for invasive bladder cancer. It not only results in the best disease-free term survival rates, but also provides the most accurate disease staging and most effective local symptom control. Recent investigations have demonstrated a clinical benefit to performance of an extended PLND, including all lymphatic tissue to the level of the aortic bifurcation. This review will summarize recent findings regarding the clinical benefits of radical cystectomy with extended lymphadenectomy, and will also examine the latest surgical techniques for optimizing the performance of this technically demanding procedure. Recent studies have demonstrated increased recurrence-free survival and overall survival rates in patients undergoing radical cystectomy with extended PLND, even in cases of pathologically lymph node negative disease. The growing use of minimally invasive techniques has prompted interest in robotic radical cystectomy and extended PLND, and recent reports have demonstrated the feasibility of this technique. The standardization of extended PLND templates has also been a focus of contemporary research. Contemporary research strongly suggests that all patients undergoing radical cystectomy for bladder cancer should undergo concomitant extended PLND. Randomized trials are still needed to confirm the benefits of extended over 'standard' PLND, and to clarify which patients may receive the greatest benefit from this procedure.

Vascular endothelial growth factor-C (VEGF-C) expression predicts lymph node metastasis of transitional cell carcinoma of the bladder.

2005-02-01

It has been found that expression of vascular endothelial growth factor-C (VEGF-C) in several carcinomas is significantly associated with angiogenesis, lymphangiogenesis and regional lymph node metastasis. However, VEGF-C expression in bladder transitional cell carcinoma (TCC) has not yet been reported. To elucidate the role of VEGF-C in bladder TCC, we examined VEGF-C expression in bladder TCC and pelvic lymph node metastasis specimens obtained from patients who underwent radical cystectomy. Eighty-seven patients who underwent radical cystectomy for clinically organ-confined TCC of the bladder were enrolled in the present study. No neoadjuvant treatments, except transurethral resection of the tumor, were given to these patients. The VEGF-C expressions of 87 bladder tumors and 20 pelvic lymph node metastasis specimens were examined immunohistochemically and the association between VEGF-C expression and clinicopathological factors, including angiogenesis as evaluated by microvessel density (MVD), was also examined. Vascular endothelial growth factor-C expression was found in the cytoplasm of tumor cells, but not in the normal transitional epithelium. Vascular endothelial growth factor-C expression was significantly associated with the pathological T stage (P = 0.0289), pelvic lymph node metastasis (P < 0.0001), lymphatic involvement (P = 0.0008), venous involvement (P = 0.0002) and high MVD (P = 0.0043). The multivariate analysis demonstrated that VEGF-C expression and high MVD in bladder TCC were independent risk factors influencing the pelvic lymph node metastasis. Moreover, the patients with VEGF-C-positive tumors had significantly poorer prognoses than those with the VEGF-C-negative tumors (P = 0.0087) in the univariate analysis. The multivariate analysis based on Cox proportional hazard model showed that the independent prognostic factors were patient age (P = 0.0132) and pelvic lymph node metastasis (P = 0.0333). The present study suggests that VEGF-C expression is an important predictive factor of pelvic lymph node metastasis in bladder cancer patients.

To evaluate the relationship between surgeon volume of radical cystectomy (RC) and postoperative morbidity, and to assess the economic burden of bladder cancer in the USA. We captured all patients who underwent RC (International Classification of Diseases, ninth revision, code 57.71) between 2003 and 2010, using a nationwide hospital discharge database. Patient, hospital and surgical characteristics were evaluated. The annual volume of RCs performed by the surgeons was divided into quintiles. Multivariable regression models were developed, adjusting for clustering and survey weighting, to evaluate the outcomes, including 90-day major complications (Clavien grade III-V) and direct patient costs. We adjusted for clustering and weighting to achieve a nationally representative analysis. The weighted cohort included 49,792 patients who underwent RC, with an overall 90-day major complication rate of 16.2%. Compared with surgeons performing one RC annually, surgeons performing ≥7 RCs each year had 45% lower odds of major complications (odds ratio [OR] 0.55; P < 0.001) and lower costs by $1690 (P = 0.02). Results were consistent when we analysed surgeon volume as a continuous variable and when we examined the surgeons with the highest volumes (≥28 cases annually), which showed markedly lower odds of major complications compared with the surgeons with the lowest volumes (OR 0.45, 95% CI 0.31-0.67; P < 0.001). Compared with patients who did not have any complications, those who had a major complication were associated with significantly higher 90-day median direct hospital costs ($43,965 vs $24,341; P < 0.001). We showed that there was an inverse relationship between surgeon volume and the development of postoperative 90-day major complication rates as well as direct hospital costs. Centralisation of RC to surgeons with higher volumes may reduce the development of postoperative major complications, thereby decreasing the burden of bladder cancer on the healthcare system. © 2014 The Authors.

Little is known about the disparity of choices between three urinary diversions after radical cystectomy, focusing on patient and institutional factors. We identified urothelial carcinoma patients who received radical cystectomy with cutaneous ureterostomy, ileal conduit or continent reservoir using the Japanese Diagnosis Procedure Combination database from 2007 to 2012. Data comprised age, sex, comorbidities (converted into the Charlson index), TNM classification (converted into oncological stage), hospitals' academic status, hospital volume, bed volume and geographical region. Multivariate ordinal logistic regression analyses fitted with the proportional odds model were performed to analyze factors affecting urinary diversion choices. For dependent variables, the three diversions were converted into an ordinal variable in order of complexity: cutaneous ureterostomy (reference), ileal conduit and continent reservoir. Geographical variations were also examined by multivariate logistic regression models. A total of 4790 patients (1131 cutaneous ureterostomies [23.6 %], 2970 ileal conduits [62.0 %] and 689 continent reservoirs [14.4 %]) were included. Ordinal logistic regression analyses showed that male sex, lower age, lower Charlson index, early tumor stage, higher hospital volume (≥3.4 cases/year) and larger bed volume (≥450 beds) were significantly associated with the preference of more complex urinary diversion. Significant geographical disparity was also found. Good patient condition and early oncological status, as well as institutional factors, including high hospital volume, large bed volume and specific geographical regions, are independently related to the likelihood of choosing complex diversions. Recognizing this disparity would help reinforce the need for clinical practice uniformity.

Life expectancy in developed countries is continuously increasing. Hence elderly patients are becoming more common in our clinical practice. Currently, one of the greatest challenges of medicine is balancing the life expectancy of elderly patients against aggressive treatments that carry significant risks. To outline the complications and survival in surgical patients 80 years and over undergoing radical cystectomy for bladder cancer. A review of a radical cystectomy in elderly recorded in four different institutional prospective databases during the period between 1991 and 2014. Clinical and pathologic features, complications and survival were evaluated. A total of 111 patients were available. Median (range) age 82.2 (80-89) years. Seventeen women and 94 men. Regarding the ASA score, 6 patients were ASA I, 47 patients were ASA II, 49 patients ASA III and 9 ASA IV. Prior to surgery, 48 patients had hydronephrosis. The median (range) creatinine series was 1.1 (0.71-11.1) ng/dL. In 88 cases an ileal conduit was performed, 17 a cutaneous ureterostomy diversion, 5 neobladders and 1 ureterosigmoidostomy case. The median (range) operative time was 230 (120-420) min and a total of 97 patients required blood transfusion. The median (range) hospital stay was 14 (7-126) days. The early and late complication rates were 50.4% and 32%, respectively. A total of 14 patients (12.6%) required surgical reintervention. Eight patients (7.2%) died in the immediate postoperative period. The readmission rate of the series was 27.2%. The mean follow-up of the series was 18 (0.27-134.73) months. During this period 66 patients died, 52 of them due to the tumor. Twelve month tumour progression free survival was 83.9% for ≤pT1, 70.2% for pT2 and 36% for ≥pT3, respectively. Twelve month cancer specific survival was 85.6% for ≤pT1, 75.1% for pT2 and 42.5% for ≥pT3, respectively. Radical cystectomy in elderly population is an aggressive surgical treatment with a significant complication rate, hospital readmission and perioperative mortality rate. Careful selection of patients is essential in order to minimize the complications of this surgery and balance benefits against risks in the elderly population. Tumour progression and cancer specific survival are poor for patients with ≥pT3 disease. Alternatives such as tri-modality therapy need to be considered within a multi-disciplinary approach. More data is required to determine which sub-groups of elderly patients would benefit from a complication, survival and quality of life perspective. © 2015 The Authors BJU International © 2015 BJU International Published by John Wiley & Sons Ltd.

To systematically evaluate the safety and efficacy of intra-operative cell salvage (ICS) in urology. A search of Medline, Embase and Cochrane Library to August 2017 was performed using methods pre-published on PROSPERO. Reporting followed the Preferred Reporting Items for Systematic Review and Meta-analysis guidelines. Eligible titles were comparative studies published in English utilising ICS in urology. Primary outcomes were allogeneic transfusion rates (ATR) and tumour recurrence. Secondary outcomes were complications and cost. Fourteen observational studies were identified, totaling 4,536 patients. ICS was compared to no blood conservation technique (seven studies), pre-operative autologous donation (PAD) (five) or both (two). Cohorts underwent open prostatectomy (eleven studies), open cystectomy (two) or open partial nephrectomy (one). Meta-analysis was possible only for ATR within prostatectomy studies. In this setting, ICS reduced ATR compared with no blood conservation technique (OR 0.34, 95% CI 0.15-0.76) but not PAD (OR 0.76, 95% CI 0.39-1.31). In the non-prostatectomy setting, ATR amongst ICS patients was significantly higher or similar in one and two studies respectively. Tumour recurrence was found to be significantly less common (two studies), similar (eight) or not measured (four). All six studies reporting complications found no difference for ICS cohorts. Regarding cost, one study from 1995 found ICS more expensive than PAD, while two more recent studies found ICS cheaper than no blood conservation technique. Due to inter-study heterogeneity, meta-analyses were not possible for recurrence, complications or cost. Low level evidence exists that compared with other blood conservation techniques, ICS reduces ATR and cost while not affecting complications. It does not appear to increase tumour recurrence post-prostatectomy, although follow-up durations are short. Small size and short follow-up negate conclusions on recurrence following nephrectomy or cystectomy. Randomised trials with long term follow-up evaluating ICS in urology are required.

2012-01-01

Bladder cancer represents a considerable issue in Egypt and the Middle East. Radical cystectomy and orthotopic neobladder represent the standard of care for managing cases with invasive bladder tumour. There are few cases reported in the literature considering the urothelial recurrence in the urethra, connected to neobladder. We are presenting a rare case of a young female patient, with an aggressive urothelial tumour, recurring 13-year post-radical cystectomy, and the Studer neobladder. Our case was managed by urethrectomy and conversion of the neobladder into continent reservoir, with good short-term oncological and functional outcomes. We can conclude that bladder cancer cases should be followed thoroughly throughout their life. Follow-up urethroscopy and cytology should be done for all cases of post-radical cystectomy, regardless of patients’ symptoms. Key message Late urothelial recurrence of post-radical cystectomy is possible and, in our case, happened 13 years following surgery. The Studer neobladder can be safely converted into continent reservoir, allowing good functional outcomes. Also, recurrence in the Studer neobladder can be safely managed, allowing good oncological outcomes, without the need for any ureteroileal interventions. PMID:22973413

To establish the current standard for open radical cystectomy (ORC) in England, as data entry by surgeons performing RC to the British Association of Urological Surgeons (BAUS) database was mandated in 2013 and combining this with Hospital Episodes Statistics (HES) data has allowed comprehensive outcome analysis for the first time. All patients were included in this analysis if they were uploaded to the BAUS data registry and reported to have been performed in the 2 years between 1 January 2014 and 31 December 2015 in England (from mandate onwards) and had been documented as being performed in an open fashion (not laparoscopic, robot assisted or the technique field left blank). The HES data were accessed via the HES website. Office of Population Censuses and Surveys Classification of Surgical Operations and Procedures version 4 (OPCS-4) Code M34 was searched during the same 2-year time frame (not including M34.4 for simple cystectomy or with additional minimal access codes Y75.1-9 documenting a laparoscopic or robotic approach was used) to assess data capture. A total of 2 537 ORCs were recorded in the BAUS registry and 3 043 in the HES data. This indicates a capture rate of 83.4% of all cases. The median operative time was 5 h, harvesting a median of 11-20 lymph nodes, with a median blood loss of 500-1 000 mL, and a transfusion rate of 21.8%. The median length of stay was 11 days, with a 30-day mortality rate of 1.58%. This is the largest, contemporary cohort of ORCs in England, encompassing >80% of all performed operations. We now know the current standard for ORC in England. This provides the basis for individual surgeons and units to compare their outcomes and a standard with which future techniques and modifications can be compared. © 2018 The Authors BJU International © 2018 BJU International Published by John Wiley & Sons Ltd.

Postoperative ileus occurs in different degrees, in the majority of patients undergoing radical cystectomy, which may increase the length of hospital stay. The use of chewing gum has demonstrated its effectiveness in reducing time-to-bowel function and the length of hospital stay in several surgical procedures. To evaluate the benefit of post-operative chewing gum use in patients undergoing radical cystectomy through a systematic review of the literature and meta-analysis. We performed a literature search of MedLine, Scopus, CochraneLibrary and ClinicalTrials.Gov in March 2017 according to the Cochrane Handbook and the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes. The studies were evaluated according to the "Oxford Center for Evidence-Based Medicine" criteria. The outcome measures evaluated were time-to-flatus, time-to-defecation, length of the hospital stay, and the rates of general and gastrointestinal postoperative complications. Continuous and dichotomous variables were compared respectively using weighted means differences and odds ratios with 95 % confidence intervals. The presence of publication bias was examined by funnel plots. Three studies (including 274 patients in total) met the inclusion criteria. The pooled results demonstrated a 11.82hour reduction in time-to-flatus (95 % CI : -15.43, -8.22h, P <0.00001), and 19.57hours in time-to-defecation (95 % CI : -29.33, -9.81h, P <0.0001), and a decreasing trend of 2.85 days in the length of the hospital stay (95 % CI : -6.13, -0.43, P=0.09), by the use of chewing gum. There was no significant difference between the "chewing gum" and "control" groups in terms of general and gastrointestinal complications (Peto Odds ratio 1.04 [0.60, 1.79], 95 % CI, P=0.89 and Peto Odds ratio 0.65 [0.26, 1.61], 95 % CI, P=0.35 respectively). Chewing gum may be recommended postoperatively in patients undergoing radical cystectomy to improve time-to-bowel function. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

 To measure the association between a surgeon's degree of specialization in a specific procedure and patient mortality.  Retrospective analysis of Medicare data.  US patients aged 66 or older enrolled in traditional fee for service Medicare.  25 152 US surgeons who performed one of eight procedures (carotid endarterectomy, coronary artery bypass grafting, valve replacement, abdominal aortic aneurysm repair, lung resection, cystectomy, pancreatic resection, or esophagectomy) on 695 987 patients in 2008-13.  Relative risk reduction in risk adjusted and volume adjusted 30 day operative mortality between surgeons in the bottom quarter and top quarter of surgeon specialization (defined as the number of times the surgeon performed the specific procedure divided by his/her total operative volume across all procedures).  For all four cardiovascular procedures and two out of four cancer resections, a surgeon's degree of specialization was a significant predictor of operative mortality independent of the number of times he or she performed that procedure: carotid endarterectomy (relative risk reduction between bottom and top quarter of surgeons 28%, 95% confidence interval 0% to 48%); coronary artery bypass grafting (15%, 4% to 25%); valve replacement (46%, 37% to 53%); abdominal aortic aneurysm repair (42%, 29% to 53%); lung resection (28%, 5% to 46%); and cystectomy (41%, 8% to 63%). In five procedures (carotid endarterectomy, valve replacement, lung resection, cystectomy, and esophagectomy), the relative risk reduction from surgeon specialization was greater than that from surgeon volume for that specific procedure. Furthermore, surgeon specialization accounted for 9% (coronary artery bypass grafting) to 100% (cystectomy) of the relative risk reduction otherwise attributable to volume in that specific procedure.  For several common procedures, surgeon specialization was an important predictor of operative mortality independent of volume in that specific procedure. When selecting a surgeon, patients, referring physicians, and administrators assigning operative workload may want to consider a surgeon's procedure specific volume as well as the degree to which a surgeon specializes in that procedure.

Patterns of Failure After Radical Cystectomy for pT3-4 Bladder Cancer: Implications for Adjuvant Radiation Therapy

DOE Office of Scientific and Technical Information (OSTI.GOV)

Reddy, Abhinav V.; Pariser, Joseph J.; Pearce, Shane M.

2016-04-01

Purpose: In patients with muscle-invasive bladder cancer, local-regional failure (LF) has been reported to occur in up to 20% of patients following radical cystectomy. The goals of this study were to describe patterns of LF, as well as assess factors associated with LF in a cohort of patients with pT3-4 bladder cancer. This information may have implications towards the use of adjuvant radiation therapy. Methods and Materials: Patients with pathologic T3-4 N0-1 bladder cancer were examined from an institutional radical cystectomy database. Preoperative demographics and pathologic characteristics were examined. Outcomes included overall survival and LF. Local-regional failures were defined usingmore » follow-up imaging reports and scans, and the locations of LF were characterized. Variables were tested by univariate and multivariate analysis for association with LF and overall survival. Results: A total of 334 patients had pT3-4 and N0-1 disease after radical cystectomy and bilateral pelvic lymph node dissection. Of these, 46% received perioperative chemotherapy. The median age was 71 years old, and median follow-up was 11 months. On univariate analysis, margin status, pT stage, and pN stage, were all associated with LF (P<.05), however, on multivariate analysis, only pT and pN stages were significantly associated with LF (P<.05). Three strata of risk were defined, including low-risk patients with pT3N0 disease, intermediate-risk patients with pT3N1 or pT4N0 disease, and high-risk patients with pT4N1 disease, who had a 2-year incidence of LF of 12%, 33%, and 72%, respectively. The most common sites of pelvic relapse included the external and internal iliac lymph nodes (LNs) and obturator LN regions. Notably, 34% of patients with LF had local-regional only disease at the time of recurrence. Conclusions: Patients with pT4 or N1 disease have a 2-year risk of LF that exceeds 30%. These patients may be the most likely to benefit from local adjuvant therapies.« less

Purpose Neoadjuvant cisplatin-based chemotherapy is standard of care for muscle-invasive bladder cancer (MIBC); however, it is infrequently adopted in practice because of concerns regarding toxicity and delay to cystectomy. We hypothesized that three cycles of neoadjuvant accelerated methotrexate, vinblastine, doxorubicin, and cisplatin (AMVAC) would be safe, shorten the time to surgery, and yield similar pathologic complete response (pT0) rates compared with historical controls. Patients and Methods Patients with cT2-T4a and N0-N1 MIBC were eligible and received three cycles of AMVAC with pegfilgrastim followed by radical cystectomy with lymph node dissection. The primary end point was pT0 rate. Telomere length (TL) and p53 mutation status were correlated with response and toxicity. Results Forty-four patients were accrued; 60% had stage III to IV disease; median age was 64 years. Forty patients were evaluable for response, with 15 (38%; 95% CI, 23% to 53%) showing pT0 at cystectomy, meeting the primary end point of the study. Another six patients (14%) were downstaged to non–muscle invasive disease. Most (82%) experienced only grade 1 to 2 treatment-related toxicities. There were no grade 3 or 4 renal toxicities and no treatment-related deaths. One patient developed metastases and thus did not undergo cystectomy; all others (n = 43) proceeded to cystectomy within 8 weeks after last chemotherapy administration. Median time from start of chemotherapy to cystectomy was 9.7 weeks. TL and p53 mutation did not predict response or toxicity. Conclusion AMVAC is well tolerated and results in similar pT0 rates with 6 weeks of treatment compared with standard 12-week regimens. Further analysis is ongoing to ascertain whether molecular alterations in tumor samples can predict response to chemotherapy. PMID:24821881

The Will Rogers phenomenon in urological oncology.

2008-01-01

Improvement in the prognosis of patient groups due to stage or grade reclassification is called the Will Rogers phenomenon. We determined the significance of the Will Rogers phenomenon in urological oncology. Studies referring to the Will Rogers phenomenon in urological oncology were identified through a MEDLINE search. Samples of articles not referring to the phenomenon directly but likely to be biased by it, such as articles comparing contemporary data to historical controls, were also reviewed. In prostate cancer the Will Rogers phenomenon is the result of the late 1990s acceptance that Gleason scores 2 to 4 should not be assigned on prostate biopsy. Consequently grade inflation occurred and current readings are almost 1 Gleason grade higher compared to past readings of the same biopsy. The result is an illusion of improvement in grade adjusted prognosis. In bladder cancer the Will Rogers phenomenon arises from improvement in histopathological processing of cystectomy specimens enabling the identification of microscopic perivesical fat infiltration and lymph node metastases not recognized in the past. Up staging from pT2 to pT3 and N0 to N+ may partly explain the improved stage adjusted survival after radical cystectomy observed in contemporary series. The Will Rogers phenomenon may also explain the correlation between the total number of lymph nodes removed at radical cystectomy and survival. As more lymph nodes are removed the probability of identifying metastases and up staging to N+ increases. Comparison of contemporary results to historical controls may be biased by the Will Rogers phenomenon. Ignoring the possibility of stage or grade reclassification may lead to erroneous conclusions.

Purpose Injection of mitomycin C may increase the success of transurethral incision of the bladder neck for the treatment of bladder neck contracture. We evaluated the efficacy of mitomycin C injection across multiple institutions. Materials and Methods Data on all patients who underwent transurethral incision of the bladder neck with mitomycin C from 2009 to 2014 were retrospectively reviewed from 6 centers in the TURNS. Patients with at least 3 months of cystoscopic followup were included in the analysis. Results A total of 66 patients underwent transurethral incision of the bladder neck with mitomycin C and 55 meeting the study inclusion criteria were analyzed. Mean ± SD patient age was 64 ± 7.6 years. Dilation or prior transurethral incision of the bladder neck failed in 80% (44 of 55) of patients. Overall 58% (32 of 55) of patients achieved resolution of bladder neck contracture after 1 transurethral incision of the bladder neck with mitomycin C at a median followup of 9.2 months (IQR 11.7). There were 23 patients who had recurrence at a median of 3.7 months (IQR 4.2), 15 who underwent repeat transurethral incision of the bladder neck with mitomycin C and 9 of 15 (60%) who were free of another recurrence at a median of 8.6 months (IQR 8.8), for an overall success rate of 75% (41 of 55). Incision with electrocautery (Collins knife) was predictive of success compared with cold knife incision (63% vs 50%, p=0.03). Four patients experienced serious adverse events related to mitomycin C and 3 needed or are planning cystectomy. Conclusions The efficacy of intralesional injection of mitomycin C at transurethral incision of the bladder neck was lower than previously reported and was associated with a 7% rate of serious adverse events.

Actually, the perinatal ovarian cysts are increasingly being diagnosed by prenatal and neonatal ultrasound. We reported our experience in the surgical management of perinatal ovarian cysts. Patients and methods. We have reviewed the clinical charts of 10 female newborns diagnosed of ovarian cysts who underwent surgical management in our hospital from 1989 to 2009. The ovarian cysts were diagnosed antenatally in 8 cases and period neonatal in 2 cases. The clinical presentation was asymptomatic abdominal mass in 7 cases. Ultrasound confirmed the ovarian mass in 8 patients. CT scan and MRI were necessary for confirm suspected diagnosis in two patients. Ultrasonography showed 7 complex cysts and 3 simple cysts. Surgery of the complicated cysts revealed ovarian torsion in 5 cases and 1 hemorragic cyst. At surgery, 5 patients underwent salpingooophorectomy, 2 patients needed oophorectomy and in 3 cases only cystectomy were necessary. The ovarian torsion is the most common complication and the cause of loss of the ovary. The neonatal ovarian cysts greater than 5 centimetres, symptomatic cysts, complex cysts and cysts persisting for more than 6 months need surgical intervention.

There are few reports of pregnancy complicated by a primary borderline parovarian tumor. A 32-year-old pregnant woman was found to have an ovarian tumor. At 13 weeks of gestation, cystectomy was performed and a diagnosis of primary borderline parovarian tumor was made. At 38 weeks of gestation, she underwent cesarean section combined with a restaging operation. A normal infant was delivered and there were no signs of recurrence. Currently, the patient is being followed for 24 months after the initial treatment and all imaging data show no evidence of recurrence. This report includes a short review of the existing literature on this topic and documents this case in detail. This case demonstrates the appropriate procedure for evaluating and treating a primary borderline parovarian tumor during pregnancy. PMID:26623422

To characterize the frequency and timing of complications following radical cystectomy in a cohort of patients treated at community and academic hospitals. Radical cystectomy patients captured from NSQIP hospitals from January 1 2006 to December 31 2012 were included. Baseline information and complications were abstracted by study surgical clinical reviewers through a validated process of medical record review and direct patient contact. We determined the incidence and timing of each complication and calculated their associations with patient and operative characteristics. 2303 radical cystectomy patients met inclusion criteria. 1115 (48%) patients were over 70 years old and 1819 (79%) were male. Median hospital stay was 8 days (IQR 7-13 days). 1273 (55.3%) patients experienced at least 1 post-operative complication of which 191 (15.6%) occurred after hospital discharge. The most common complication was blood transfusion (n = 875; 38.0%), followed by infectious complications with 218 (9.5%) urinary tract infections, 193 (8.4%) surgical site infections, and 223 (9.7%) sepsis events. 73 (3.2%) patients had fascial dehiscence, 82 (4.0%) developed a deep vein thrombosis, and 67 (2.9%) died. Factors independently associated with the occurrence of any post-operative complication included: age, female gender, ASA class, pre-operative sepsis, COPD, low serum albumin concentration, pre-operative radiotherapy, pre-operative transfusion >4 units, and operative time >6 hours (all p<0.05). Complications remain common following radical cystectomy and a considerable proportion occur after discharge from hospital. This study identifies risk factors for complications and quality improvement needs.

[Radical cystectomy and urinary diversion-what is important ?

PubMed

Noldus, J; Niegisch, G; Pycha, A; Karl, A

2018-06-01

In Germany, radical cystectomy with urinary diversion is the primary therapeutic option for localized muscle invasive urothelial bladder cancer. Modifications in the pre-, peri-, and postoperative phase have significantly improved outcomes. Different factors and parameters are directly associated with patients' outcome. An overview on how to best approach this procedure is provided in this article. The data regarding preparation and the procedure for the radical cystectomy followed by urinary diversion are separately analyzed. During the preoperative phase, Fast Track and ERAS (Enhanced Recovery after Surgery) concepts should be an integral part of therapeutic management. Different aspects of such models are presented and discussed. Comorbidities such as diabetes mellitus, hypertension, malnutrition or anemia should also be treated early. In the perioperative phase, optimized fluid management and close interaction with the anesthesiologist are needed. Use of vasopressors during surgery and controlled hypotension (about 80 mm Hg) help reduce perioperative blood loss. Blood product use should be minimized. The use of epidural anesthesia to improve the stress reaction of the body improves pain management and functional recovery. Radical cystectomy is associated with the best oncological outcome, preserving functional structures to maintain a good quality of life. Nerve-sparing procedures in men and women should be used where appropriate. The use of robotic assisted radical cystectomy (RARC) is also discussed. The ileum conduit is still the most common urinary diversion worldwide. However, numerous other urinary diversions to provide patients with the highest quality of life are available. Centers with a high case load seem to be associated with an improved outcome.

Cost analysis of open radical cystectomy versus robot-assisted radical cystectomy.

2013-02-01

Bladder cancer is the fourth and ninth most common malignancy in males and females, respectively, in the U.S. and one of the most costly cancers to manage. With the current economic condition, physicians will need to become more aware of cost-effective therapies for the treatment of various malignancies. Robot-assisted radical cystectomy (RARC) is the latest minimally invasive surgical option for muscle-invasive bladder cancer. Current reports have shown less blood loss, a shorter hospital stay, and a lower morbidity with RARC, as compared with the traditional open radical cystectomy (ORC), although long-term oncologic results of RARC are still maturing. There are few studies that have assessed the cost outcomes of RARC as compared with ORC. Currently, ORC appears to offer a direct cost advantage due to the high purchase and maintenance cost of the robotic platform, although when the indirect costs of complications and extended hospital stay with ORC are considered, RARC may be less expensive than the traditional open procedure. In order to accurately evaluate the cost effectiveness of RARC versus ORC, prospective randomized trials between the two surgical techniques with long-term oncologic efficacy are needed.

To confirm gender specific differences in pathologic factors and survival rates of urothelial bladder cancer patients treated with radical cystectomy. We conducted a retrospective monocentric study on 701 patients treated with radical cystectomy and pelvic lymphadenectomy for muscle invasive bladder cancer. Impact of gender on recurrence rate, specific and non-specific mortality rate were evaluated using Cox regression models in univariate and multivariate analysis. We collected data on 553 males (78.9%) and 148 females (21.1%) between 1998 and 2011. Both groups were comparable at inclusion regarding age, pathologic stage, nodal status and lymphovascular invasion. Mean follow-up time was 45 months (interquartile 23-73) and by that time, 163 patients (23.3%) had recurrence of their tumor and 127 (18.1%) died from their disease. In multivariable Cox regression analyses, female gender was independently associated with disease recurrence (RR: 1.73; 95% CI 1.22-2.47; P=0.02) and cancer-specific mortality (RR=2.50, 95% CI=1.71-3.68; P<0.001). We confirmed female gender to be an independent negative prognosis factor for patients following a radical cystectomy and lymphadenectomy for an invasive muscle bladder cancer.

Are we doing "better"? The discrepancy between perception and practice of enhanced recovery after cystectomy principles among urologic oncologists.

PubMed

2016-03-01

The concept of enhanced recovery after surgery has been around since the 1990s when it was first introduced as a means to improve postoperative recovery of general surgical patients. In the field of urology, the uptake of enhanced recovery pathways has been slow for unclear reasons. Recently, interest in enhanced recovery after cystectomy (ERAC) has been increasing, but the current urologic oncology practice patterns remain unclear. In this study, we investigate modern perioperative patterns of care and rates of application of ERAC principles by cystectomy surgeons. ERAC principles were identified by reviewing urology and general surgery literature. An adapted version of The Royal College of Surgeons of England fast-track surgical principles survey was used. Preoperative education, bowel preparation avoidance, nasogastric tubes avoidance, normothermia, opioid avoidance, early ambulation, and early feeding were all practices queried with the survey. Surveys were distributed electronically to faculty of Society of Urologic Oncology fellowships with bladder cancer as a special area of interest. Additional participants were identified by recent publications on cystectomies for bladder cancer. In total, 128 surveys were e-mailed to the previously identified experts. Of these, 61 (48%) completed the survey. Responses were classified as congruent with commonly accepted ERAC principles (ERAC group) or noncongruent (non-ERAC group). Chi-square test was used for categorical variables and Wilcoxon-Mann-Whitney for ordinal variables. Of the urologists who classified themselves in the ERAC group (64%), the average length of stay was reported to be 6.1 days and 7.2 days in the non-ERAC group (P = 0.02). Only 20% were practicing all interventions. Among the ERAC surgeons 1, 2 or 3 of the interventions were omitted by 13%, 25%, and 23% of the respondents, respectively. Significant differences were found between the self-reported ERAC adopters and nonadopters in the use of bowel preparation (P = 0.01), nasogastric tubes (P = 0.007), alvimopan (P<0.001), and the average day of advancement to clear liquids (P<0.001). There were no differences in postoperative ambulation and opiate or nonsteroidal anti-inflammatory drug use. Lack of convincing evidence was cited as the main reason for the non-ERAC group not yet implementing an ERAC pathway followed by lack of resource availability. Urologists who consider themselves as practicing ERAC do not universally practice all of the pathway tenets. A significant gap exists between self-perception and practice of enhanced recovery. ERAC implementation is challenging but represents a significant opportunity to improve the quality of care for cystectomy patients. Copyright © 2016 Elsevier Inc. All rights reserved.

We instituted a ketamine-predominant analgesic regimen in the peri- and postoperative periods to limit the effects of narcotic analgesia on bowel function in patients undergoing radical cystectomy. The primary end points of interest were time to return of bowel function, time to discharge, and efficacy of the analgesic regimen. We performed a retrospective chart review of patients undergoing robotic-assisted laparoscopic cystectomy (RARC) with urinary diversion by a single surgeon at our institution from January 1, 2011 to June 30, 2012. Patients receiving the opioid-minimizing ketamine protocol were compared to a cohort of patients undergoing RARC with an opioid-predominant analgesic regimen. In total, 15 patients (Group A) were included in the ketamine-predominant regimen and 25 patients (Group B) in the opioid-predominant control group. Three patients (19%) in Group A discontinued the protocol due to ketamine side effects. The mean time to bowel movement and length of stay in Group A versus Group B was 3 versus 6 days (p < 0.001), and 4 versus 8 days, respectively (p < 0.001). Group A patients received an average of 13.0 mg of morphine versus 97.5 mg in Group B (p < 0.001). Patients who received our ketamine pain control regimen had a shorter time to return of bowel function and length of hospitalization after RARC. Our study has its limitations as a retrospective, single surgeon, single institution study and the non-randomization of patients. Notwithstanding these limitations, this study was not designed to show inferiority of one approach, but instead to show that our protocol is safe and efficacious, warranting further study in a prospective fashion.

Radical cystectomy (RC) for urothelial carcinoma of the bladder (UCB) is associated with heterogeneous functional and oncological outcomes. The aim of this study was to generate trifecta and pentafecta criteria to optimize outcome reporting after RC. We interviewed 50 experts to consider a virtual group of patients (age ≤ 75 years, ASA score ≤ 3) undergoing RC for a cT2 UCB and a final histology of ≤pT3pN0M0. A ranking was generated for the three and five criteria with the highest sum score. The criteria were applied to the Prospective Multicenter Radical Cystectomy Series 2011. Multivariable binary logistic regression analyses were used to evaluate the impact of clinical and histopathological parameters on meeting the top selected criteria. The criteria with the highest sum score were negative soft tissue surgical margin, lymph node (LN) dissection of at least 16 LNs, no complications according to Clavien-Dindo grade 3-5 within 90 days after RC, treatment-free time between TUR-BT with detection of muscle-invasive UCB and RC <3 months and the absence of local UCB-recurrence in the pelvis ≤12 months. The first three criteria formed trifecta, and all five criteria pentafecta. A total of 334 patients qualified for final analysis, whereas 35.3 and 29 % met trifecta and pentafecta criteria, respectively. Multivariable analyses showed that the relative probability of meeting trifecta and pentafecta decreases with higher age (3.2 %, p = 0.043 and 3.3 %, p = 0.042) per year, respectively. Trifecta and pentafecta incorporate essential criteria in terms of outcome reporting and might be considered for the improvement of standardized quality assessment after RC for UCB.

To investigate whether a history of non-muscle-invasive bladder cancer (NMIBC) plays a prognostic role in patients with muscle-invasive bladder cancer (MIBC) treated with radical cystectomy in the era when neoadjuvant chemotherapy was established as standard therapy for MIBC. A total of 282 patients who were diagnosed with cT2-T4aN0M0 bladder cancer treated with open radical cystectomy at our institutions were included. Initially diagnosed MIBC without a history of NMIBC was defined as primary MIBC group (n = 231), and MIBC that progressed from NMIBC was defined as progressive MIBC (n = 51). The rate of cT3/4a tumors was significantly higher in the primary MIBC group than in the progressive MIBC group (P = .004). Five-year recurrence-free survival and cancer-specific survival (CSS) rates for the primary MIBC group versus progressive MIBC group were 68.2% versus 55.9% (P = .039) and 76.1% versus 61.6% (P = .005), respectively. Progressive MIBC (hazard ratio, 2.170; P = .008) was independently associated with cancer death. In the primary MIBC group, the 5-year CSS rate in patients treated with neoadjuvant chemotherapy was 85.4%, which was significantly higher than that in patients without (71.5%, P = .023). In the progressive MIBC group, no significant differences were observed in CSS between patients treated with and without neoadjuvant chemotherapy. MIBC that progressed from NMIBC had a significantly worse clinical outcome than MIBC without a history of NMIBC and may not respond as well to neoadjuvant chemotherapy. These results are informative, even for NMIBC patients treated with conservative intravesical therapy. Copyright © 2018 Elsevier Inc. All rights reserved.

Purpose: Treatment for small-cell carcinoma of the bladder is largely guided by case reports, retrospective reviews, and small prospective trials. This study aimed to study outcomes using a large population-based database. Methods: The Surveillance, Epidemiology, and End Results-Medicare database (1991-2005) was used to analyze how different treatment combinations of specific bladder surgeries, chemotherapy, and radiation affected patient outcomes. Trends in the use of these combinations over time were also analyzed. Results: A total of 533 patients were retrieved from the database. A bladder-sparing approach involving transurethral resection of the bladder tumor (TURBT) combined with chemotherapy and radiation yielded no significantmore » difference in overall survival compared with patients undergoing at least a cystectomy (of whom over 90% received radical cystectomy) with chemotherapy (p > 0.05). The analysis of treatment trends indicated that these two general strategies for cure combined to account for fewer than 20% of patients. A majority of patients (54%) received TURBT as their only surgical treatment, and a subset analysis of these patients indicated that chemotherapy played a role in all stages of disease (p < 0.05) whereas radiation improved overall survival in regional-stage disease (p < 0.05). Conclusion: Relatively few patients with small-cell carcinoma of the bladder receive potentially curative therapies. Chemotherapy should be a major component of treatment. Cystectomy and bladder-sparing approaches represent two viable strategies and deserve further investigation to identify the patients who may benefit from organ preservation or not. In addition, the role of radiation in regional-stage disease should be investigated further, because it positively affects survival after TURBT.« less

The objective of this study was to identify nutritional preoperative factors associated with complications after radical cystectomy (RC). We prospectively evaluated the Mini-Nutritional Assessment Score, body mass index (BMI), appetite, stool frequency, hydration, food intake, weight loss, albuminemia, and prealbuminemia of 144 patients who underwent RC between January 2011 and April 2014. Postoperative complications were defined as any adverse event reported in the patient's file up to 90 days after surgery. Each complication was classified according to the Clavien-Dindo and Memorial Sloan-Kettering Cancer Center systems. The adjusted relative risk (RR) computed through a Poisson regression model was used to identify nutritional risk factors associated with post-RC complications. A high BMI >27 kg/m 2 was associated with higher risk of low-grade complications (RR:1.47 [95% CI,1.09-2.00]) at 7 days and a four-fold increased risk of cardiac complications at 7 and 90 days (RR:3.77 [1.15-12.32] and RR:3.28 [1.35-7.98]). Decreased appetite was associated with low-grade (RR:1.43 [1.03-1.99] complications within 90 days. Preoperative weight loss >3 kg was associated with high-grade (RR:2.49 [1.23-5.05]) and wound (RR:2.51 [1.23-5.10]) complications within 90 days. This study showed that preoperative nutritional status of patients may predict the occurrence of complications up to 90 days post-RC. Development of preoperative nutritional interventions may reduce the deleterious impact of RC on patients' health.

Cystectomy combined with pelvic lymph-node dissection and urinary diversion entails high morbidity and mortality. Improvements are needed, and a first step is to collect information on the current situation. In 2011, this group took the initiative to start a population-based database in Sweden (population 9.5 million in 2011) with prospective registration of patients and complications until 90 days after cystectomy. This article reports findings from the first year of registration. Participation was voluntary, and data were reported by local urologists or research nurses. Perioperative parameters and early complications classified according to the modified Clavien system were registered, and selected variables of possible importance for complications were analysed by univariate and multivariate logistic regression. During 2011, 285 (65%) of 435 cystectomies performed in Sweden were registered in the database, the majority reported by the seven academic centres. Median blood loss was 1000 ml, operating time 318 min, and length of hospital stay 15 days. Any complications were registered for 103 patients (36%). Clavien grades 1-2 and 3-5 were noted in 19% and 15%, respectively. Thirty-seven patients (13%) were reoperated on at least once. In logistic regression analysis elevated risk of complications was significantly associated with operating time exceeding 318 min in both univariate and multivariate analysis, and with age 76-89 years only in multivariate analysis. It was feasible to start a national population-based registry of radical cystectomies for bladder cancer. The evaluation of the first year shows an increased risk of complications in patients with longer operating time and higher age. The results agree with some previously published series but should be interpreted with caution considering the relatively low coverage, which is expected to be higher in the future.

Purpose: To perform a comprehensive comparison of overall survival (OS), disease-specific survival (DSS), progression-free survival (PFS), and treatment-related complications between radical cystectomy (RC) and combined modality treatment (CMT—radiation therapy, concurrent chemotherapy, and maximal transurethral resection of bladder tumor) in the setting of muscle-invasive bladder cancer. Methods and Materials: We searched 7 databases (PubMed, Scopus, EMBASE, Proquest, CINAHL, and (ClinicalTrials.gov)) for randomized, controlled trials and prospective and retrospective studies directly comparing RC with CMT from database inception to March 2016. We conducted meta-analyses evaluating OS, DSS, and PFS with hazard ratios (HRs) and 95% confidence intervals (CIs). Results: Nineteen studies evaluating 12,380 subjects weremore » selected. For the 8 studies encompassing 9554 subjects eligible for meta-analyses, we found no difference in OS at 5 years (HR 0.96, favoring CMT, 95% CI 0.72-1.29; P=.778) or 10 years (HR 1.02, favoring cystectomy, 95% CI 0.73-1.42; P=.905). No difference was observed in DSS at 5 years (HR 0.83, favoring radiation, 95% CI 0.54-1.28; P=.390) or 10 years (HR 1.17, favoring cystectomy, 95% CI 0.89-1.55; P=.264), or PFS at 10 years (HR 0.85, favoring CMT, 95% CI 0.43-1.67; P=.639). The cystectomy arms had higher rates of early major complications, whereas rates of minor complications were similar between the 2 treatments. Conclusion: Current meta-analysis reveals no differences in OS, DSS, or PFS between RC and CMT. Further randomized, controlled trials are necessary to identify the optimal treatment for specific patients.« less

Do we have biomarkers to predict response to neoadjuvant and adjuvant chemotherapy and immunotherapy in bladder cancer?

PubMed Central

Wezel, Felix; Vallo, Stefan

Radical cystectomy (RC) is the standard of care treatment of localized muscle-invasive bladder cancer (BC). However, about 50% of patients develop metastases within 2 years after cystectomy. Neoadjuvant cisplatin-based chemotherapy before cystectomy improves the overall survival (OS) in patients with muscle-invasive BC. Pathological response to neoadjuvant treatment is a strong predictor of better disease-specific survival. Nevertheless, some patients do not benefit from chemotherapy. The identification of reliable biomarkers enabling clinicians to identify patients who might benefit from chemotherapy is a very important clinical task. An identification tool could lead to individualized therapy, optimizing response rates. In addition, unnecessary treatment with chemotherapy which potentially leads to a loss of quality of life and which might also might cause a delay of cystectomy in a neoadjuvant setting could be avoided. The present review aims to summarize and discuss the current literature on biomarkers for the prediction of response to systemic therapy in muscle-invasive BC. Tremendous efforts in genetic and molecular characterization have led to the identification of predictive candidate biomarkers in urothelial carcinoma (UC), although prospective validation is pending. Ongoing clinical trials examining the benefit of individual therapies in UC of the bladder (UCB) by molecular patient selection hold promise to shed light on this question. PMID:29354494

To identify symptom distress and clusters in patients 3 months after radical cystectomy and to explore their potential predictors. A cross-sectional design was used to investigate 99 bladder cancer patients 3 months after radical cystectomy. Data were collected by demographic and disease characteristic questionnaires, the symptom experience scale of the M.D. Anderson symptom inventory, two additional symptoms specific to radical cystectomy, and the functional assessment of cancer therapy questionnaire. A factor analysis, stepwise regression, and correlation analysis were applied. Three symptom clusters were identified: fatigue-malaise, gastrointestinal, and psycho-urinary. Age, complication severity, albumin post-surgery (negative), orthotropic neobladder reconstruction, adjuvant chemotherapy and American Society of Anesthesiologists (ASA) scores were significant predictors of fatigue-malaise. Adjuvant chemotherapy, orthotropic neobladder reconstruction, female gender, ASA scores and albumin (negative) were significant predictors of gastrointestinal symptoms. Being unmarried, having a higher educational level and complication severity were significant predictors of psycho-urinary symptoms. The correlations between clusters and for each cluster with quality of life were significant, with the highest correlation observed between the psycho-urinary cluster and quality of life. Bladder cancer patients experience concurrent symptoms that appear to cluster and are significantly correlated with quality of life. Moreover, symptom clusters may be predicted by certain demographic and clinical characteristics.

During the childbearing years, the standard fertility-sparing treatment for bilateral borderline ovarian tumours (BOTs) is the unilateral oophorectomy plus controlateral cystectomy. The aim of the present study was to compare the effects of two laparoscopic fertility-sparing surgical procedures for the treatment of bilateral BOTs on recurrence and fertility in young women who desire to conceive as soon as possible. Thirty-two women affected by bilateral early-stage BOTs who desired to conceive were randomized to receive bilateral cystectomy (experimental group, n=15) or oophorectomy plus controlateral cystectomy (control group, n=17). At the first recurrence after childbearing completion, each patient was treated with non-conservative standard treatment. Recurrences and reproductive events were recorded. After a follow-up period of 81 months (19 inter-quartile; 60-96 range), the cumulative pregnancy rate (CPR) (14/15 versus 9/17; P=0.003) and the cumulative probability of first pregnancy (P= 0.011) were significantly higher in the experimental than in control group. No significant (P=0.358) difference between groups was detected in cumulative probability of first recurrence. The laparoscopic bilateral cystectomy followed by non-conservative treatment performed at the first recurrence after the childbearing completion is an effective surgical strategy for patients with bilateral early-stage BOTs who desire to conceive as soon as possible.

Although open radical cystectomy (ORC) is still the standard approach, laparoscopic radical cystectomy (LRC) and robot-assisted radical cystectomy (RARC) are increasingly performed. To report on a systematic literature review and cumulative analysis of pathologic, oncologic, and functional outcomes of RARC in comparison with ORC and LRC. Medline, Scopus, and Web of Science databases were searched using a free-text protocol including the terms robot-assisted radical cystectomy or da Vinci radical cystectomy or robot* radical cystectomy. RARC case series and studies comparing RARC with either ORC or LRC were collected. A cumulative analysis was conducted. The searches retrieved 105 papers, 87 of which reported on pathologic, oncologic, or functional outcomes. Most series were retrospective and had small case numbers, short follow-up, and potential patient selection bias. The lymph node yield during lymph node dissection was 19 (range: 3-55), with half of the series following an extended template (yield range: 11-55). The lymph node-positive rate was 22%. The performance of lymphadenectomy was correlated with surgeon and institutional volume. Cumulative analyses showed no significant difference in lymph node yield between RARC and ORC. Positive surgical margin (PSM) rates were 5.6% (1-1.5% in pT2 disease and 0-25% in pT3 and higher disease). PSM rates did not appear to decrease with sequential case numbers. Cumulative analyses showed no significant difference in rates of surgical margins between RARC and ORC or RARC and LRC. Neoadjuvant chemotherapy use ranged from 0% to 31%, with adjuvant chemotherapy used in 4-29% of patients. Only six series reported a mean follow-up of >36 mo. Three-year disease-free survival (DFS), cancer-specific survival (CSS), and overall survival (OS) rates were 67-76%, 68-83%, and 61-80%, respectively. The 5-yr DFS, CSS, and OS rates were 53-74%, 66-80%, and 39-66%, respectively. Similar to ORC, disease of higher pathologic stage or evidence of lymph node involvement was associated with worse survival. Very limited data were available with respect to functional outcomes. The 12-mo continence rates with continent diversion were 83-100% in men for daytime continence and 66-76% for nighttime continence. In one series, potency was recovered in 63% of patients who were evaluable at 12 mo. Oncologic and functional data from RARC remain immature, and longer-term prospective studies are needed. Cumulative analyses demonstrated that lymph node yields and PSM rates were similar between RARC and ORC. Conclusive long-term survival outcomes for RARC were limited, although oncologic outcomes up to 5 yr were similar to those reported for ORC. Although open radical cystectomy (RC) is still regarded as the standard treatment for muscle-invasive bladder cancer, laparoscopic and robot-assisted RCs are becoming more popular. Templates of lymph node dissection, lymph node yields, and positive surgical margin rates are acceptable with robot-assisted RC. Although definitive comparisons with open RC with respect to oncologic or functional outcomes are lacking, early results appear comparable. Copyright © 2014 European Association of Urology.

Health-Related Quality of Life after Cystectomy and Urinary Diversion for Bladder Cancer

PubMed Central

Shih, Cheryl; Porter, Michael P.

2011-01-01

With multiple options for urinary diversion after radical cystectomy for bladder cancer that have comparable cancer control and complication rates, health-related quality of life (HRQOL) has become an important consideration. This article reviews the methods for defining HRQOL, the challenges in measuring HRQOL in bladder cancer, and the literature comparing HRQOL after various methods of urinary diversion. Recent contributions include the validation of HRQOL instruments specific to bladder cancer and the publication of several prospective studies measuring HRQOL outcomes after cystectomy and urinary diversion. There is no convincing evidence from existing literature that any particular method of urinary diversion offers superior HRQOL outcomes. Rather, there is growing evidence that good HRQOL can be achieved with patient education and consideration of each patient's clinical and psychosocial situation. Future research should utilize the validated bladder cancer specific HRQOL instruments and perhaps explore the impact of preoperative counseling on postoperative HRQOL. PMID:21826139

In radical cystectomy, under-nutrition is common and has detrimental physiological and clinical effects, which can lead to increased complications and prolonged recovery. This article compares measurements and outcomes across continents in this patient population with advanced bladder cancer. The association of preoperative nutritional risk, nutritional status, and length of stay is equal across continents, and the results promote increased clinical awareness that women at severe risk should be identified preoperatively.

Prediction of mortality after radical cystectomy for bladder cancer by machine learning techniques.

Bladder cancer is a common cancer in genitourinary malignancy. For muscle invasive bladder cancer, surgical removal of the bladder, i.e. radical cystectomy, is in general the definitive treatment which, unfortunately, carries significant morbidities and mortalities. Accurate prediction of the mortality of radical cystectomy is therefore needed. Statistical methods have conventionally been used for this purpose, despite the complex interactions of high-dimensional medical data. Machine learning has emerged as a promising technique for handling high-dimensional data, with increasing application in clinical decision support, e.g. cancer prediction and prognosis. Its ability to reveal the hidden nonlinear interactions and interpretable rules between dependent and independent variables is favorable for constructing models of effective generalization performance. In this paper, seven machine learning methods are utilized to predict the 5-year mortality of radical cystectomy, including back-propagation neural network (BPN), radial basis function (RBFN), extreme learning machine (ELM), regularized ELM (RELM), support vector machine (SVM), naive Bayes (NB) classifier and k-nearest neighbour (KNN), on a clinicopathological dataset of 117 patients of the urology unit of a hospital in Hong Kong. The experimental results indicate that RELM achieved the highest average prediction accuracy of 0.8 at a fast learning speed. The research findings demonstrate the potential of applying machine learning techniques to support clinical decision making. Copyright © 2015 Elsevier Ltd. All rights reserved.

To evaluate the morbidity and mortality of laparoscopic cystectomy combined with transileal ureterostomy to treat neurogenic vesicosphincteric disorders. Prospective study performed between february 2004 and april 2006 on 26 consecutive patients with a mean age of 55.0 +/- 12.7 years treated by laparoscopic cystectomy for neurogenic vesicosphincteric disorders. The underlying neurological disease was multiple sclerosis (MS) in 20 cases, spinal cord injury in 4 cases and transverse myelitis in 2 cases. The median preoperative ASA score was 3 (range: 2-3). No open conversion was necessary. One intraoperative complication was observed (vascular injury). No perioperative death was observed. The nasogastric tube was maintained postoperatively for an average of 8.69 +/- 5.9 hours. The mean time to resumption of oral fluids was 1.4 +/- 0.7 days and mean time to resumption of solids was 2.6 +/- 1.0 days. The mean time to resumption of bowel movements was 3.8 +/- 3.2 days. The mean intensive care stay was 3.9 +/- 1.1 days. Two postoperative complications were observed in the same patient (ileus and bronchial congestion). Postoperative narcotic analgesics were necessary in 60% of cases. The mean hospital stay was 10.3 +/- 4.1 days. Two late postoperative complications were observed in the same patient (two episodes of pyelonephritis). Laparoscopic cystectomy has a low morbidity in neurological patients, allowing early return of feeding and a moderate length of hospital stay.

Complex, recurrent vesicovaginal fistulas (VVFs) can be very challenging to repair and often require interposition of nonirradiated, well-vascularized tissue between the urinary system and vagina. We report our experience using a rectus abdominus myofascial (RAM) interposition flap for VVF repair. A retrospective analysis was performed to identify patients who had undergone VVF repair with RAM interposition. Data were collected focusing on preoperative patient characteristics, etiology of VVF, intraoperative parameters, including surgical techniques, and postoperative patient outcomes. We used a RAM interposition flap for VVF repair in 5 patients. All VVFs had developed postoperatively; no patient had received radiotherapy. VVF developed after total abdominal hysterectomy (TAH) or radical cystectomy in 3 and 2 cases, respectively. Both cases of VVF after radical cystectomy occurred in conjunction with orthotopic diversion (neobladder-vaginal fistula). In 3 patients with post-TAH VVF, a total of five previous failed repairs were attempted before RAM interposition. In 1 patient with a neobladder-vaginal fistula, who had received adjuvant chemotherapy, RAM interposition failed, and the patient ultimately required cutaneous urinary diversion after two subsequent failed attempts at repair (68 months of follow-up). The remaining 4 patients (80%) had no evidence of recurrent VVF or voiding abnormalities at a mean follow-up of 19 months (range 8 to 32). Rectus abdominus muscle can be a successful interposition flap during repair of complex, recurrent VVF. In our experience, this has been successful in most cases, particularly in younger patients with nonmalignant processes.

To examine the inhibitory effects of tumor necrosis factor-α on myogenic differentiation of human urethral rhabdosphincter cells. A rhabdosphincter sample was obtained from a patient who underwent total cystectomy. To expand the lifespan of the primary cultured cells, rhabdosphincter myogenic cells were immortalized with mutated cyclin-dependent kinase 4, cyclin D1 and telomerase. The differential potential of the cells was investigated. The transfected human rhabdosphincter cells were induced for myogenic differentiation with recombinant human tumor necrosis factor-α and/or the tumor necrosis factor-α antagonist etanercept at different concentrations, and activation of signaling pathways was monitored. Human rhabdosphincter cells were selectively cultured for at least 40 passages. Molecular analysis confirmed the expression of myosin heavy chain, which is a specific marker of differentiated muscle cells, significantly increased after differentiation induction. Although tumor necrosis factor-α treatment reduced the myosin heavy chain expression in a concentration-dependent manner, etanercept inhibited this suppression. Tumor necrosis factor-α suppressed phosphorylation of protein kinase B and p38, whereas etanercept pretreatment promoted phosphorylation and myosin heavy chain expression in a concentration-dependent manner. Tumor necrosis factor-α inhibits differentiation of urethral rhabdosphincter cells in part through the p38 mitogen-activated protein kinase and phosphoinositide 3-kinase pathways. Inhibition of tumor necrosis factor-α might be a useful strategy to treat stress urinary incontinence. © 2017 The Japanese Urological Association.

We aimed to assess contemporary rates of neoadjuvant chemotherapy (NC) use. We relied on the Surveillance, Epidemiology and End Results (SEER)-Medicare database for non-metastatic, muscle-invasive (T2-T4a) urothelial carcinoma of the urinary bladder (UCUB) patients who underwent radical cystectomy (RC) between 1991 and 2009. Multivariable logistic regression analyses tested predictors of NC use, such as: T-stage, N-stage, year of diagnosis, age at diagnosis, gender, race, use of radiotherapy (RT), marital status, urban status, socioeconomic status, tumour grade, and Charlson comorbidity index (CCI). Overall, 5207 patients treated with RC were identified. Of those, 332 (6.4%) received NC. The rate of NC increased over time from 6.1% (1991) to 15.0% (2009) (p<0.001). In multivariable analyses, year of diagnosis (odds ratio [OR]: 4.7; p<0.001), lower T-stage (T3 vs. T2: OR: 0.7; p=0.003), married status (OR: 1.5; p=0.006), and younger age at diagnosis (≥80 vs. 66-69: OR: 0.6; p=0.006) were associated with a higher odds of NC; all represented independent predictors of NC use. Neither race nor CCI demonstrated statistical significance. We reported lower than anticipated overall (6.4%) use of NC. Nonetheless, the rate increased from 6.1% (1991) to 15.0% (2009). Older and unmarried individuals were less likely to receive NC. NC rates were higher in T2 UCUB patients. Some of the observed discrepancies, such as lower use in unmarried individuals, may require correction. Better adherence to guidelines should be encouraged and implemented, especially based on the confirmed benefits of NC according to randomized, controlled trials. The study is limited by a retrospective design and limited variables.

Thyroid cysts are rare in cats and poorly documented. To report distinguishing clinical features and treatment responses of cats with thyroid cysts. Forty client-owned cats. Retrospective review of medical records for cats with thyroid cysts confirmed by scintigraphy, ultrasound, magnetic resonance imaging, or necropsy at 4 referral centers between 2005 and 2016. Signalment, clinical findings, diagnostic testing, treatment, and outcome were recorded. Cats ranged in age from 8 to 20 years with no apparent breed or sex predilection. 37 of 40 (93%) cats were hyperthyroid (duration, 1-96 months). Clinical findings included palpable neck mass (40/40, 100%), weight loss (15/40, 38%), dysphagia (8/40, 20%), decreased appetite (5/40, 13%), and dyspnea (4/40, 10%). Cysts were classified as small (≤8 cm 3 ) in 16 (40%) and large (>8 cm 3 ) in 24 (60%) cats. Of 25 cats treated with radioiodine, hyperthyroidism resolved in 23 (92%), whereas thyroid cysts resolved in 12 (50%). Radioiodine treatment resolved small cysts in 8 of 13 (62%) cats and large cysts in 4 of 11 (36%) cats. Eight cats, including 2 euthyroid cats, underwent thyroid-cystectomy; 3 with bilateral thyroid involvement were euthanized postoperatively for hypocalcemia. Excised cystic thyroid masses were identified as cystadenoma (4) and carcinoma (4). Thyroid cysts are encountered in hyperthyroid and euthyroid cats with benign and malignant thyroid tumors. Radioiodine treatment alone inconsistently resolved thyroid cysts. Thyroid-cystectomy could be considered in cats with unilateral thyroid disease or when symptomatic cysts persist despite successful radioiodine treatment of hyperthyroidism.

To clarify the discrepancy in the incidence and severity of surgical site infections (SSI) for radical cystectomy between reports based on the CDC guideline and those using the Clavien-Dindo classification we evaluated 449 consecutive patients who underwent radical cystectomy for bladder cancer between 1990 and 2012. Of the 115 (25.6%) patients with SSI defined by the CDC guideline, 89 could be analyzed. We compared the SSI rates and severity defined by the CDC guideline and Clavien-Dindo classifications. There were 58 patients with superficial SSI, 16 with deep SSI, and 15 with organ/space SSI according to the CDC guideline. All patients with organ/space SSI were judged as "not having SSI" by the Clavien-Dindo classification. They were classified as having "intestinal prolapse", "intestinal fistula", "abdominal abscess" and "pelvic abscess." There was a significant association between the treatment duration and depth of SSI based on the CDC guideline by Spearman's rank-correlation coefficient (p < 0.001, r = 0.614) and with the grade of complications (p < 0.001, r = 0.632) in the Clavien-Dindo classification. Multivariate analysis showed that patients with grade III SSI in the Clavien-Dindo classification needed a significantly longer treatment duration. It is necessary to be aware that a discrepancy can occur automatically due to the different natures of the definitions. Using the CDC guideline, we can effectively estimate the future treatment period when SSI occurs. With the Clavien-Dindo classification, grade III SSI requires a longer treatment duration.

We undertook a systematic evaluation of the prognostic value of numerous histologic factors in 165 radical cystectomies (RC) of patients with invasive urothelial carcinoma who underwent surgery after neoadjuvant chemotherapy (NAC). Tumor regression grade (TRG) and therapy-related stromal and epithelial changes were also recorded. Locally advanced disease (≥pT2 and/or pN+) was present in 64% of patients, 22% had no evidence of residual carcinoma (pT0+pN0) and 28% had no evidence of residual muscle invasive carcinoma (≤pT1+N0). TRG 1, 2, and 3 were found in 32%, 15%, and 50% of patients, respectively. Histologic variants of UC were reported in 25% of cases. The most common therapy-related stromal change was fibroblastic reaction (78%) and the most common epithelial change in residual UC was smudgy and poorly preserved chromatin (28%). Prominent stromal and epithelial changes were noted in 41% and 5% of RC, respectively. Progression was found in 45% of patients and cancer-related deaths occurred in 30%. Multivariate analysis showed that the only independent prognostic parameters for progression were T stage, N stage, lymphovascular invasion, and the margin status. Similarly, only T stage, N stage, and the margin status correlated with cancer-related deaths. Neither TRG, nor any of the stromal or epithelial-related variables correlated with outcome. We confirm that the traditional and routinely-reported histologic parameters in RC post-NAC remain the most powerful prognosticators of disease course. The significance of TRG in the bladder remains unconfirmed. This article is protected by copyright. All rights reserved. This article is protected by copyright. All rights reserved.

Laparoscopic Extracorporeal Oophorectomy and Ovarian Cystectomy in Second Trimester Pregnant Obese Patients

PubMed Central

Chung, Maurice K.; Chung, Rosemary P.

Objectives: To determine whether a modified technique for laparoscopic extracorporal oophorectomy is less complicated and safer than traditional laparoscopic oophorectomy. Methods: Four obese patients in their second trimester underwent open laparoscopy for treatment of large ovarian cysts. A Cook Ob/Gyn special cyst aspirator with a 14-gauge aspirating needle was inserted into the abdomen to drain the ovary through a separate 10-mm port; the site of insertion depends on the location of the ovary. After the cyst was decompressed, the 10-mm incision was enlarged to 3 cm, and either extracorporal oophorectomy or cystectomy was performed. Results: No complications occurred. Average blood loss was less than 15 cc; average carbon dioxide insufflation time was less than 20 minutes. Average operating time was 40 minutes, which was significantly less than traditional laparoscopic oophorectomy. The patients were discharged in less than 23 hours. Patient A had a 500-cc dermoid cyst, and subsequently had a normal vaginal delivery at term. Patient B had a 1600-cc cyst removed. She had a cesarian delivery due to cephalopelvic dispro-portion. Pathological analysis of the specimen identified the mass as a dermoid cyst and serous cystadenoma. Patient C had a 3200-cc ovarian cyst. Currently, she is in her 24th week of gestation. Patient D had a 700-cc simple ovarian cyst removed at her 16th week of gestation. Conclusions: Laparoscopic extracorporal oophorectomy requires significantly less CO2 insufflation time and a shorter operation time, hence, decreasing the adverse effects on the fetus. The enlarged second trimester uterus made traditional laparoscopy more complicated. Performing the procedure extracorporally decreased the possibility of operative complications. PMID:11548835

Cystectomy and urinary diversion is an excellent example for the growing complexity of the G-DRG (German diagnosis-related groups) system. Based on different diagnoses (malignant tumor of the urinary tract, benign disease of the urinary tract, malignant tumor of the female genital tract, or malignant tumor of the male genital tract), identical cases may lead to very different codes, resulting in even more differences in reimbursement.

Between March, 1976, and December, 1982, 70 of 157 patients (45%) undergoing single-stage radical cystectomy with pelvic lymphadenectomy and urinary diversion with the intent to cure invasive bladder cancer were found to have pathologic Stage P3B, P4 and/or N + disease. Thirty-four of the 70 patients received adjuvant prophylactic chemotherapy after cystectomy and 36 patients were followed expectantly. From 1976 through 1977 adjuvant chemotherapy consisted of cyclophosphamide 1 Gm/M2 each month for six months; from 1978 through June, 1980, adjuvant chemotherapy consisted of cis-platinum 100 mg/M2 each month for four months with the exception of 1 patient treated more aggressively with combination chemotherapy (CISCA). Since July, 1980, a prospective study has been utilized in which patients were randomized into two groups, Group A receiving combination chemotherapy and Group B followed up expectantly; adjuvant chemotherapy appears to result in a slight delay in time to relapse but no influence in overall survival was observed.

Long-Term Outcomes Among Patients Who Achieve Complete or Near-Complete Responses After the Induction Phase of Bladder-Preserving Combined-Modality Therapy for Muscle-Invasive Bladder Cancer: A Pooled Analysis of NRG Oncology/RTOG 9906 and 0233

Purpose: To investigate the differences in outcomes among patients with muscle-invasive bladder cancer on NRG Oncology Radiation Therapy Oncology Group protocols 9906 and 0233 who achieved complete response and near-complete response after induction chemoradiation and then completed bladder-preserving therapy with chemoradiation therapy (chemo-RT) to full dose (60-64 Gy). Patients and Methods: A pooled analysis was performed on 119 eligible patients with muscle-invasive bladder cancer enrolled on NRG Oncology Radiation Therapy Oncology Group trials 9906 and 0233, who were classified as having a complete (T0) or near-complete (Ta or Tis) response after induction chemo-RT and completed consolidation with a total RT dose ofmore » at least 60 Gy. Bladder recurrence, salvage cystectomy rates, and disease-specific survival were estimated by the cumulative incidence method and bladder-intact and overall survivals by the Kaplan-Meier method. Results: Among the 119 eligible patients, 101 (85%) achieved T0, and 18 (15%) achieved Ta or Tis after induction chemo-RT and proceeded to consolidation. After a median follow-up of 5.9 years, 36 of 101 T0 patients (36%) versus 5 of 18 Ta or Tis patients (28%) experienced bladder recurrence (P=.52). Thirteen patients among complete responders eventually required late salvage cystectomy for tumor recurrence, compared with 1 patient among near-complete responders (P=.63). Disease-specific, bladder-intact, and overall survivals were not significantly different between T0 and Ta/Tis cases. Conclusions: The bladder recurrence and salvage cystectomy rates of the complete and the near-complete responders were similar. Therefore it is reasonable to recommend that patients with Ta or Tis after induction chemo-RT continue with bladder-sparing therapy with consolidation chemo-RT to full dose (60-64 Gy).« less

Carcinoma in situ (CIS) is a poor prognostic finding in urothelial carcinoma. However, its significance in muscle-invasive urothelial carcinoma (MIUC) treated with neoadjuvant chemotherapy (NAC) is uncertain. We assessed the effect of CIS found in pretreatment transurethral resection of bladder tumor (TURBT) biopsies on the pathologic and clinical outcomes. Subjects with MIUC treated with NAC before cystectomy were identified. The pathologic complete response (pCR) rates stratified by TURBT CIS status were compared. The secondary analyses included tumor response, progression-free survival (PFS), overall survival (OS), and an exploratory post hoc analysis of patients with pathologic CIS only (pTisN0) at cystectomy. A total of 137 patients with MIUC were identified. TURBT CIS was noted in 30.7% of the patients. The absence of TURBT CIS was associated with a significantly increased pCR rate (23.2% vs. 9.5%; odds ratio = 4.08; 95% CI: 1.19-13.98; P = 0.025). Stage pTisN0 disease was observed in 19.0% of the TURBT CIS patients. TURBT CIS status did not significantly affect the PFS or OS outcomes. Post hoc analysis of the pTisN0 patients revealed prolonged median PFS (104.5 vs. 139.9 months; P = 0.055) and OS (104.5 vs. 152.3 months; P = 0.091) outcomes similar to those for the pCR patients. The absence of CIS on pretreatment TURBT in patients with MIUC undergoing NAC was associated with increased pCR rates, with no observed differences in PFS or OS. Isolated CIS at cystectomy was frequently observed, with lengthy PFS and OS durations similar to those for pCR patients. Further studies aimed at understanding the biology and clinical effect of CIS in MIUC are warranted. Copyright © 2018 Elsevier Inc. All rights reserved.

The value of lymph node dissection (LND) in the treatment of bladder urothelial carcinoma is well established. However, standards for the quality of LND remain controversial. We compared the distribution of lymph node (LN) metastases in a two-institution cohort of patients undergoing radical cystectomy (RC) using a uniformly applied extended LND template. Patients undergoing RC at the University of Southern California (USC) Institute of Urology and at Oregon Health Sciences University (OHSU) were included if they met the following criteria: (1) no prior pelvic radiotherapy or LND; (2) lymphatic tissue submitted from all nine predesignated regions, including the paracaval and para-aortic LNs; (3) bladder primary; and (4) category M0 disease. The number and location of LN metastases were prospectively entered into corresponding databases. LN maps were constructed and correlated with preoperative and pathologic characteristics. Kaplan-Meier curves were constructed to estimate overall survival (OS) and recurrence free survival (RFS) among LN-positive (LN+) patients. Inclusion criteria were met by 646 patients (439 USC, 207 OHSU), and 23% had LN metastases at time of cystectomy. Although there was a difference in the median per-patient LN count between institutions, there were no significant interinstitutional differences in the incidence or distribution of positive LNs, which were found in 11% of patients with ≤pT2b and in 44% of patients with ≥pT3a tumors. Among LN+ patients, 41% had positive LNs above the common iliac bifurcation. Estimated 5-yr RFS and OS rates for LN+ patients were 45% and 33%, respectively, and did not differ significantly between institutions. LN metastases in regions outside the boundaries of standard LND are common. Adherence to meticulous dissection technique within an extended template is likely more important than total LN count for achieving optimal oncologic outcomes.

Cost-effectiveness of open versus laparoscopic versus robotic-assisted laparoscopic cystectomy and urinary diversion.

To provide insight into the recently published cost comparisons in the context of open, laparoscopic, and robotic-assisted laparoscopic radical cystectomy and to demonstrate the complexity of such economic analyses. Most economic evaluations are from a hospital perspective and summarize short-term perioperative therapeutic costs. However, the contributing factors (e.g. study design, included variables, robotic amortization plan, supply contract, surgical volume, surgeons' experience, etc.) vary substantially between the institutions. In addition, a real cost-effective analysis considering cost per quality-adjusted life-year gained is not feasible because of the lack of long-term oncologic and functional outcome data with the robotic procedure. On the basis of a modeled cost analysis using results from published series, robotic-assisted cystectomy was - with few exceptions - found to be more expensive when compared with the open approach. Immediate costs are affected most by operative time, followed by length of hospital stay, robotic supply, case volume, robotic cost, and transfusion rate. Any complication substantially impacts overall costs. Economic cost evaluations are complex analyses influenced by numerous factors that hardly allow an interinstitutional comparison. Robotic-assisted cystectomy is constantly refined with many institutions being somewhere on their learning curve. Transparent reports of oncologic and functional outcome data from centers of expertise applying standardized methods will help to properly analyze the real long-term benefits of robotic surgery and successor technologies and prevent us from becoming slaves of successful marketing strategies.

To evaluate various prognostic factor predictors of residual growth in Relook transurethral resection of bladder tumor (TURBT) in superficial bladder cancer. Also, to evaluate the role of Relook TURBT along with the ploidy for prediction of recurrence and stage progression in these patients. Fifty patients with superficial bladder cancer underwent TURBT after complete evaluation. Ploidy of the tumor specimen was evaluated by flow cytometry. After 4 to 6 weeks of initial TURBT, these patients underwent Relook TURBT. Final treatment was given after the results of the histological evaluation of these specimens. Patients who underwent bladder sparing treatment were followed-up. Of the patients, 28.5% had residual tumor in Relook TURBT. Growth was found to be at the same site in 66.7% and at a different site 33.3%; 75% had single while 25% had multiple residual growth. Residual malignant tissue had a statistically significant correlation with size of the tumor (>3 cm), appearance (solid tumor), number (>3), grade (high), and multiple previous resections. Overall, the up-migration of stage and grade leads to change in treatment in 41.6%; 5 underwent radical cystectomy and 1 opted for radiotherapy; in 2 patients, intravesical BCG was given. In follow-up of mean 11.5 months, 16.6% had recurrence. Presence of residual growth in Relook TURBT along with number, size, morphology, and multiple previous resections were found to have significant correlation with the recurrence in these patients. Ploidy and grade of the tumor were not found to have correlation. Multiple, more than 3 cm, solid high grade tumor with > 3 previous resections were predictors of presence of residual tumor in Relook TURBT. Presence of residual growth is a significant risk factor for recurrence. Ploidy was not found to be significantly correlated with recurrence.

Background: Enhanced recovery pathways, also known as fast-track protocols, have been adopted since the early 2000s by various surgical specialties with the goal of improving patient outcomes and reducing the cost burden of major surgery on the health care system. Objective: To review the scientific literature on the origin of enhanced recovery pathways, track the contemporary utilization of such practices for patients undergoing radical cystectomy, and analyze the available data regarding their effect on morbidity, mortality, and treatment cost. Methods: A literature search of multiple electronic databases was undertaken. Manuscripts including patients undergoing radical cystectomy were chosen based on predefined criteria with an emphasis on randomized controlled trials and cohort studies. Strength of evidence for each study that met inclusion criteria was assessed based on the risk of bias, consistency, directness, and precision. Results: Database searches resulted in 1,236 potentially relevant articles. A total of 485 articles were selected for full-text dual review and 106 studies in 52 publications met the inclusion criteria. Conclusion: The utilization of enhanced recovery pathways with the goal of improving overall patient morbidity and mortality is well supported in the literature, however standardization of implementation and adherence across institutions is lacking, and their direct efficacy on reducing preventable treatment related expenditures is unconfirmed.

Metastatic involement of penis is an exceptionally rare condition. 77% of the metastases are originated from the pelvic region; prostate and bladder are the most frequent primary locations. Retrograde venous route, retrograde lymphatic route, arterial spread, direct extension, implantation and secondary to instrumentation are the mechanisms of metastasis. Approximately two thirds of all penile metastasis are detected at a mean time of 18 months after the detection of the primary tumor and the remaining one third is presented at the same time with primary tumor. Diagnosis is usually made by biopsy and also non invasive methods as MRI or colour-coded duplex ultrasonography. Treatment options in these patients are local excision, partial or complete penectomy, external beam radiation therapy and chemotheraphy. Despite these alternatives prognosis is usually poor.We present a case of urethelial carcinoma of the bladder and coincidental prostate adenocarcinoma with penile metastasis which is presented with priapism 6 months after radical cystectomy as the first systemic manifestation. We performed biopsy initially for staging and the patient underwent MRI showing the extension of the disease. The patient underwent radiotherapy of 56 gy and priapism partially resolved after the treatment. Chemotheraphy was also planned but the patient died 3 months following radiotheraphy.

Neoadjuvant chemotherapy (NAC) for muscle-invasive bladder cancer (MIBC) provides a small but significant survival benefit. Nevertheless, controversies on applying NAC remain because the limited benefit must be weight against chemotherapy-related toxicity and the delay of definitive local treatment. Therefore, there is a clear clinical need for tools to guide treatment decisions on NAC in MIBC. Here, we aimed to validate a previously reported 20-gene expression signature that predicted lymph node-positive disease at radical cystectomy in clinically node-negative MIBC patients, which would be a justification for upfront chemotherapy. We studied diagnostic transurethral resection of bladder tumors (dTURBT) of 150 MIBC patients (urothelial carcinoma) who were subsequently treated by radical cystectomy and pelvic lymph node dissection. RNA was isolated and the expression level of the 20 genes was determined on a qRT-PCR platform. Normalized Ct values were used to calculate a risk score to predict the presence of node-positive disease. The Cancer Genome Atlas (TCGA) RNA expression data was analyzed to subsequently validate the results. In a univariate regression analysis, none of the 20 genes significantly correlated with node-positive disease. The area under the curve of the risk score calculated by the 20-gene expression signature was 0.54 (95% Confidence Interval: 0.44-0.65) versus 0.67 for the model published by Smith et al. Node-negative patients had a significantly lower tumor grade at TURBT (p = 0.03), a lower pT stage (p<0.01) and less frequent lymphovascular invasion (13% versus 38%, p<0.01) at radical cystectomy than node-positive patients. In addition, in the TCGA data, none of the 20 genes was differentially expressed in node-negative versus node-positive patients. We conclude that a 20-gene expression signature developed for nodal staging of MIBC at radical cystectomy could not be validated on a qRT-PCR platform in a large cohort of dTURBT specimens.

We aimed to develop a structured scoring tool: cystectomy assessment and surgical evaluation (CASE) that objectively measures and quantifies performance during robot-assisted radical cystectomy (RARC) for men. A multinational 10-surgeon expert panel collaborated towards development and validation of CASE. The critical steps of RARC in men were deconstructed into nine key domains, each assessed by five anchors. Content validation was done utilizing the Delphi methodology. Each anchor was assessed in terms of context, score concordance, and clarity. The content validity index (CVI) was calculated for each aspect. A CVI ≥ 0.75 represented consensus, and this statement was removed from the next round. This process was repeated until consensus was achieved for all statements. CASE was used to assess de-identified videos of RARC to determine reliability and construct validity. Linearly weighted percent agreement was used to assess inter-rater reliability (IRR). A logit model for odds ratio (OR) was used to assess construct validation. The expert panel reached consensus on CASE after four rounds. The final eight domains of the CASE included: pelvic lymph node dissection, development of the peri-ureteral space, lateral pelvic space, anterior rectal space, control of the vascular pedicle, anterior vesical space, control of the dorsal venous complex, and apical dissection. IRR > 0.6 was achieved for all eight domains. Experts outperformed trainees across all domains. We developed and validated a reliable structured, procedure-specific tool for objective evaluation of surgical performance during RARC. CASE may help differentiate novice from expert performances.

Although robot-assisted laparoscopic radical cystectomy (RARC) was first reported in 2003 and has gained popularity, comparisons with open radical cystectomy (ORC) are limited to reports from high-volume referral centers. To compare population-based perioperative outcomes and costs of ORC and RARC. A retrospective observational cohort study using the US Nationwide Inpatient Sample to characterize 2009 RARC compared with ORC use and outcomes. Propensity score methods were used to compare inpatient morbidity and mortality, lengths of stay, and costs. We identified 1444 ORCs and 224 RARCs. Women were less likely to undergo RARC than ORC (9.8% compared with 15.5%, p = 0.048), and 95.7% of RARCs and 73.9% of ORCs were performed at teaching hospitals (p<0.001). In adjusted analyses, subjects undergoing RARC compared with ORC experienced fewer inpatient complications (49.1% and 63.8%, p = 0.035) and fewer deaths (0% and 2.5%, p<0.001). RARC compared with ORC was associated with lower parenteral nutrition use (6.4% and 13.3%, p = 0.046); however, there was no difference in length of stay. RARC compared with ORC was $3797 more costly (p = 0.023). Limitations include retrospective design, absence of tumor characteristics, and lack of outcomes beyond hospital discharge. RARC is associated with lower parenteral nutrition use and fewer inpatient complications and deaths. However, lengths of stay are similar, and the robotic approach is significantly more costly.

Patients undergoing gynecology laparoscopy frequently experience shoulder pain as a common postoperative complication. Considering diaphragm stimulation in its pathophysiology, there are some advice to prevent or control this special form of referral pain. The current study aimed to assess the prophylactic effect of preoperative administration of oral gabapentin to prevent Post Laparoscopic Shoulder Pain (PLSP) after laparoscopic ovarian cystectomy. In a randomized, double blind, placebo controlled trial 40 female patients who were candidates to have elective laparoscopic ovarian cystectomy, received uniformed capsules containing gabapentin 600 mg or placebo 30 minutes before anesthesia induction. All patients had the American Society of Anesthesiologists (ASA) Physical Status of I-II and none had pervious abdominal surgery. Thereafter, the presence of side effects and PLSP and its severity was assessed by Visual Analog Scale (VAS) in the beginning of surgery and 2, 6, 12 hours after the surgery. Comparing the gabapentin (n = 20) and placebo (n = 20) groups, basic characteristics including age (P = 0.446), Body Mass Index (BMI) (P = 0.876), pregnancy history (P = 0.660), and surgery time (P = 0.232) were statistically similar. PLSP occurrence was less frequent in the gabapentin group (45%) compared with the placebo group (75%) (P = 0.053), while In gabapentin group the VAS scores were lower in 2(P = 0.004), 6 (P = 0.132), and 12 (P = 0.036) hours, post operatively. Prophylactic gabapentin administration could be considered as an effective and safe intervention to reduce occurrence and severity of PLSP after gynecologic laparoscopic cystectomy.

Robot-assisted radical cystectomy (RARC) is increasing annually for treatment of bladder cancer. The objective of this meta-analysis was to compare the safety and efficacy of RARC and open radical cystectomy (ORC) for bladder cancer. Our meta-analysis searches were conducted using PubMed, Web of Science, and Cochrane Library databases to identify randomized controlled trials (RCT) assessing the two techniques. Four RCT studies were identified, including 239 cases. Our studies indicated that RARC was associated with longer operative time (WMD: 69.69, 95% CI:17.25 to122.12; P= 0.009), lower estimated blood loss (WMD: -299.83, 95% CI:-414.66to -184.99; P<0.00001). The two groups had no significant difference in overall perioperative complications, length of hospital stay, lymph node yield and positive surgical margins. RARC is mini-invasive alternative to ORC for bladder cancer. The advantage of RARC was reduced estimated blood loss. More studies are needed to compare the two techniques.

[Stress urinary incontinence after radical cystectomy: neobladder construction and placement of the functional retrourethral sling].

Stress urinary incontinence (SUI) following radical cystectomy and orthotopic ileal neobladder construction represents a challenging problem. The incidence of incontinence following this surgery is reported to be 30-60% and is - despite a better understanding of the male (and female) pelvic anatomy - still regarded as an adverse outcome of this surgery.Therapeutic options have been limited up until now and include pharmacological agents, surgical treatment and pelvic floor training with only moderate amelioration of the symptoms and often unacceptable side effects. Nevertheless, urinary continence is probably the most important key to patient satisfaction. Here we introduce the perineal approach of the functional retrourethral mesh as a new and innovative sling suspension based on a non-obstructive procedure in a patient with urinary stress incontinence after ileal neobladder. The sling adjusts the changed anatomy after radical cystectomy returning it to the former preoperative position and thus continence can be achieved again. The approach of the sling in a patient with ileal neobladder is safe and the good result concerning continence is promising.

Hemangiopericytoma (HPC) arising from within the urinary bladder is exceptionally rare. A 45-year-old man having the symptoms of left groin pain, vague suprapubic discomfort and frequency was admitted to our clinic. Pelvic tomography revealed a tumor in the bladder wall measuring 4 x 3 cm and was not clearly distinct from the lower abdominal wall. Partial cystectomy was performed and the histopathological examination confirmed the hemangiopericytoma. Three thousand rad exterior beam irradiation was performed after operation. Partial cystectomy and adjuvant radiotherapy may be a simple and effective alternative operation for the patient with HPC.

The objective of this study is to investigate the incidence and location of lymph node metastases (LNMs) in patients undergoing radical cystectomy (RC) and lymph node dissection (LND) for clinical non-muscle invasive bladder cancer (NMIBC). Prospectively collected data of 637 patients who underwent RC and 'superextended' LND with intent-to-cure for urothelial carcinoma of the bladder between 2002 and 2008 were examined. Inclusion criteria were (a) clinical stage Ta, Tis-only, or T1, (b) muscle presence at diagnostic transurethral resection in clinical T1 patients, (c) no prior diagnosis of ≥ T2 disease, (d) no neoadjuvant therapy, and (e) lymphatic tissue sample submitted from all 13 predesignated locations. Lymph node mapping was performed in all patients to determine the location of metastatic lymph nodes. Median follow-up time was 4.7 years. Recurrence-free survival and overall survival were reported. A total of 114 patients were included of whom 9 patients (7.9%) had LNM. Stratified by clinical stage, LNM was present in 6/67 (9.0%) patients with cT1, 3/25 (12.0%) patients with cTis-only, and none of the 22 patients with cTa. Of the 9 node-positive patients (33.3%), 3 had LNM proximal to the aortic bifurcation. No skip metastases were found. After RC, 27 patients (23.7%) were upstaged to muscle invasive disease; of whom 16.7% had cT1, 2.6% had cTa, and 4.4% had cTis-only. Of the remaining 87 patients with pathologic NMIBC, 1 patient (1.1%) had LNM, limited to the true pelvis. Five-year RFS was 82.3%, 81.5%, and 62.0% in patients with pathologic NMIBC, clinical NMIBC, and pathologic muscle invasive bladder cancer, respectively. Routine LND is important in patients with cT1 and cTis-only bladder cancer, but may have limited value in patients with cTa. LNM beyond the boundaries of a standard LND occurred in up to one-third of node-positive patients. In the absence of skip metastases, however, performing a standard LND would correctly identify all node-positive patients. Whether removal of LNM proximal to the common iliac vessels provides a survival benefit remains to be evaluated in future prospective studies. Copyright © 2014 Elsevier Ltd. All rights reserved.

Purpose: To develop multi-institutional consensus clinical target volumes (CTVs) and organs at risk (OARs) for male and female bladder cancer patients undergoing adjuvant radiation therapy (RT) in clinical trials. Methods and Materials: We convened a multidisciplinary group of bladder cancer specialists from 15 centers and 5 countries. Six radiation oncologists and 7 urologists participated in the development of the initial contours. The group proposed initial language for the CTVs and OARs, and each radiation oncologist contoured them on computed tomography scans of a male and female cystectomy patient with input from ≥1 urologist. On the basis of the initial contouring, themore » group updated its CTV and OAR descriptions. The cystectomy bed, the area of greatest controversy, was contoured by another 6 radiation oncologists, and the cystectomy bed contouring language was again updated. To determine whether the revised language produced consistent contours, CTVs and OARs were redrawn by 6 additional radiation oncologists. We evaluated their contours for level of agreement using the Landis-Koch interpretation of the κ statistic. Results: The group proposed that patients at elevated risk for local-regional failure with negative margins should be treated to the pelvic nodes alone (internal/external iliac, distal common iliac, obturator, and presacral), whereas patients with positive margins should be treated to the pelvic nodes and cystectomy bed. Proposed OARs included the rectum, bowel space, bone marrow, and urinary diversion. Consensus language describing the CTVs and OARs was developed and externally validated. The revised instructions were found to produce consistent contours. Conclusions: Consensus descriptions of CTVs and OARs were successfully developed and can be used in clinical trials of adjuvant radiation therapy for bladder cancer.« less

• To assess and compare the economic burden of open radical cystectomy (OC) vs robotic-assisted laparoscopic radical cystectomy (RC) with pelvic lymph node dissection and urinary diversion. • A series of 103 and 83 consecutive patients undergoing OC and RC, respectively, were prospectively studied at a tertiary care institution from April 2002 to February 2009. • Data were collected on patient demographics, perioperative parameters and length of stay (LOS) in hospital. Cohorts were subdivided into ileal conduit (IC), continent cutaneous diversion (CCD) and orthotopic neobladder (ON) subgroups. • A linear cost model was created to simulate treatment with OC vs RC. Procedural costs were derived from the Medicare Resource Based Relative Value Scale. Materials costs were obtained from the respective suppliers. The indirect costs of complications were considered. • Sensitivity analyses were performed. • Despite a higher cost of materials, RC was less expensive than OC for IC and CCD, although the cost advantage deteriorated for ON. • The per-case costs of RC with IC, CCD and ON were $20,659, $22,102 and $22,685, respectively, compared to $25,505, $22,697 and $20,719 for their OC counterparts. • The largest cost driver in the study was LOS in hospital. • RC showed a shorter LOS compared to OC, although this effect was insufficient to offset the higher cost of robotic surgery. • Complications materially affected cost performance. • Despite a higher cost of materials, RC can be more cost efficient than OC as a treatment for bladder cancer at a high-volume, tertiary care referral centre, particularly with IC. • Complications significantly impact cost performance. © 2011 THE AUTHORS.

The purpose of this study was to investigate the association between prophylactic antibiotic administration (PAA) and post-operative infection in radical cystectomy with orthotopic neobladder urinary diversion carried out for patients with bladder cancer. Fifty-seven consecutive cases were analyzed retrospectively. Post-operative infections were categorized as urinary tract, wound, and remote infections. We used the antibiotics tazobactam/piperacillin (TAZ/PIPC), sulbactam/ampicillin (SBT/ABPC), flomoxef (FMOX), cefazolin (CEZ), cefotiam (CTM), and cefmetazole (CMZ). Twenty-five (43.9%) patients had post-operative infections. Five of these (8.77%) patients had wound infections, 22 (38.6%) patients had urinary tract infections, and 2 (3.51%) had remote infections. Our statistical analysis demonstrated that the patients with TAZ/PIPC used for PAA (5/18: 27.8%) had a significantly lower post-operative infection rate than patients with other antibiotics (24/39: 61.5%) (p = 0.0442). In addition, the patients with a shorter-duration PAA (within 72 h after the operation (48-72 h)) had a significantly lower rate of post-operative infections (12/33: 36.4%) than those with longer-duration PAA (longer than 72-96 h after the operation) (16/24: 66.7%) (p = 0.0239). Taken together, these results suggest that TAZ/PIPC with shorter PAA duration (within 72 h) might lead to a lower rate of post-operative infections. In conclusion, our data showed that PAA with TAZ/PIPC with a shorter duration PAA (within 72 h) might be recommended for radical cystectomy with orthotopic neobladder reconstruction. A prospective study based on our data is desirable to establish or revise guidelines for prophylactic medication for preventing post-operative infection after radical cystectomy with orthotopic neobladder urinary diversion.

Patients commonly use the Internet to acquire health information. While a large amount of health-related information is available, the accuracy is highly variable. We sought to evaluate the current web-based information that exists with regard to robotic cystectomy. Two common search engines (Google and Yahoo) were used to search the term "robotic cystectomy" and obtain the top 50 websites for each. These 100 sites were analyzed with regard to type of site, presence and accuracy of information on bladder cancer, and of information related to robotic cystectomy outcomes (surgical/oncologic, functional, and recovery). In addition, information taken from Intuitive Corp website was identified, as was the presence (or absence) and literature-based references. Of the 100 sites, 61 were surgeon/provider sites, 23 links to articles, 8 news stories, 3 patient support sites, 3 meeting program, and 2 were the Intuitive site. Analysis of all 61 provider sites showed that 13% provided factually accurate information, 7% had both factual and erroneous information, and 80% had no information on bladder cancer. With regard to the purported benefits and outcomes of the robotic approach, a significant number of the sites had nonevidence-based claims with regard surgical/oncologic aspects (54%), functional recovery (26%), and surgical recovery (47%). Information taken directly from the Intuitive site was found on 33% sites, with 16% sites having a direct link. Only 4 provider sites (7%) had listed any references. These findings suggest that surgeons provide the majority of Internet information but do not often present evidence-based information and often over-state claims and outcomes of the robotic approach. This highlights the need for providers to deliver factual and evidence-based information to the public, and not suggest untrue/unproven claims that seem to presently occur.

Cisplatin-based neoadjuvant chemotherapy (NAC) before radical cystectomy is the standard of care in muscle-invasive bladder cancer. There are limited data regarding chemotherapy tolerability and outcomes for patients with low glomerular filtration rate (GFR) who receive cisplatin-based NAC. A retrospective analysis of patients who received cisplatin-based NAC at Cleveland Clinic (2005-2016) was undertaken. Patients with pre-NAC GFR < 60 mL/min by either Cockcroft-Gault (CG) or Modification of Diet in Renal Disease (MDRD) formula were compared to patients with GFR ≥ 60 mL/min for NAC tolerability, pathologic complete and partial response (pPR), and the ability to undergo radical cystectomy. Thirty patients with low GFR (34-59 mL/min) and 94 patients with normal GFR (≥ 60 mL/min) were identified. Low GFR patients were older (median, 71 vs. 65 years), but other demographic and transurethral resection of bladder tumor characteristics were comparable. Low GFR patients more frequently had early NAC discontinuation (30% vs. 13%), NAC modifications (delays, dose reduction, or discontinuation, 66% vs. 40%), and cisplatin-based NAC administered in split doses (37% vs. 16%). No differences in NAC tolerability or outcomes were noted among low GFR patients receiving split-dose versus standard regimens. No differences were noted between low and normal GFR patients in NAC cycles (median, 3 for each), cystectomy rates (93% for each), time to cystectomy, and GFR change from baseline to after NAC. Pathologic complete response was higher among normal GFR patients (24% vs. 14%). Patients with low GFR had more NAC discontinuations and modifications, but most completed planned NAC cycles. For carefully selected patients with GFR < 60 mL/min, cisplatin-based NAC remains a treatment option. Copyright © 2018 Elsevier Inc. All rights reserved.

Surveillance, Epidemiology, and End Results data indicate only 19.7% of patients 80 years old or older with muscle invasive bladder cancer undergo radical cystectomy vs 49.4% of those with similar stage disease age 65 to 79 years, reflecting concern for perioperative morbidity. We evaluated the morbidity and survival outcomes of octogenarians treated with radical cystectomy at a tertiary cancer center. We conducted a retrospective review of 1,142 patients entered prospectively into a hospital based complication database between 1995 and 2005 using a modified Clavien system. Complications were classified as minor or major based on the complexity of intervention required. Disease specific and competing risk survival curves for patients younger than 80 years vs 80 years old or older were created. Octogenarians had a nonsignificantly higher rate of minor (55% vs 50%) and major complications (17% vs 13%) than younger patients, respectively (global p = 0.15). After adjusting for baseline characteristics the risk of any complication was roughly flat across all ages (p = 0.9). For major complications risk appeared to increase slightly up to age 65 years and then plateau (p = 0.16). After adjusting for deaths from other causes the cumulative incidence of death from bladder cancer in octogenarians was comparable to that in younger patients (5-year cumulative incidence of death from bladder cancer 26% vs 25%). In our experience radical cystectomy in older patients with bladder cancer provides similar disease control and survival outcomes with risks of high grade perioperative morbidity comparable to those in younger patients, and remains an important treatment option.

To develop quality assessment tool to evaluate surgical performance for robot-assisted radical cystectomy program. A prospectively maintained quality assurance database of 425 consecutive robot-assisted radical cystectomies performed by a single surgeon between 2005 and 2015 was retrospectively reviewed. Potentially modifiable factors, related to the management and perioperative care of patients, were used to evaluate patient care. Criteria included the following: preoperative (administration of neoadjuvant chemotherapy); operative (operative time <6.5 hours and estimated blood loss <500 cc); pathologic (negative soft tissue surgical margins and lymph node yield ≥20); and postoperative (no high-grade complications, readmission, or noncancer-related mortality within 30 days).The Quality Cystectomy Score (QCS) was developed (1 star: achieving ≤2 criteria or mortality within 30 days; 2 stars: 3 or 4 criteria met; 3 stars: 5 or 6 criteria met; and 4 stars: 7 or all criteria met). Univariate and multivariate Cox proportional hazard regression models were fitted to test for the association between QCS and survival outcomes. Most patients (85%) achieved at least 3 stars, and more patients achieved 4 stars with time. High QCS was associated with better recurrence-free, cancer-specific, and overall survival (P values <.05). None of the patients with 1-star were alive at 1 year. Patients with 4 stars achieved the best survival rates (recurrence-free survival [62%], cancer-specific survival [70%], and overall survival [53%] at 5 years) (log rank P < .0001). Continuous assessment for quality improvement facilitated implementation and maintenance of robot-assisted program for bladder cancer. Copyright © 2016 Elsevier Inc. All rights reserved.

Physical exercises offer a variety of health benefits to cancer survivors during and post-treatment. However, exercise-based pre-habilitation is not well reported in major uro-oncology surgery. The aim of this study was to investigate the feasibility, the adherence, and the efficacy of a short-term physical pre-habilitation program to patients with invasive bladder cancer awaiting radical cystectomy (RC). A parent prospective randomized controlled clinical trial investigated efficacy of a multidisciplinary rehabilitation program on length of stay following RC. A total of 107 patients were included in the intension-to-treat population revealing 50 patients in the intervention group and 57 patients in the standard group. Pre-operatively, the intervention group was instructed to a standardized exercise program consisting of both muscle strength exercises and endurance training. The number of training sessions and exercise repetitions was patient-reported. Feasibility was expressed as adherence to the program and efficacy as the differences in muscle power within and between treatment groups at time for surgery. A total of 66 % (95 % confidence interval (CI) 51; 78) adhered more than 75 % of the recommended progressive standardized exercise program. In the intervention group, a significant improvement in muscle power of 18 % (p < 0.002) was found at time for surgery. Moreover, muscle power was significantly improved compared to that in the standard group with 0.3 W/kg (95 % CI 0.08; 0.5 %) (p < 0.006). Adherence was not associated with pre-operative BMI, nutritional risk, comorbidity, pain, gender, or age. In patients awaiting RC, a short-term exercise-based pre-habilitation intervention is feasible and effective and should be considered in future survivorship strategies.

To perform a cost analysis comparing the cost of robot-assisted radical cystectomy (RARC) with open RC (ORC) in a UK tertiary referral centre and to identify the key cost drivers. Data on hospital length of stay (LOS), operative time (OT), transfusion rate, and volume and complication rate were obtained from a prospectively updated institutional database for patients undergoing RARC or ORC. A cost decision tree model was created. Sensitivity analysis was performed to find key drivers of overall cost and to find breakeven points with ORC. Monte Carlo analysis was performed to quantify the variability in the dataset. One RARC procedure costs £12 449.87, or £12 106.12 if the robot was donated via charitable funds. In comparison, one ORC procedure costs £10 474.54. RARC is 18.9% more expensive than ORC. The key cost drivers were OT, LOS, and the number of cases performed per annum. High ongoing equipment costs remain a large barrier to the cost of RARC falling. However, minimal improvements in patient quality of life would be required to offset this difference. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

The role of adjuvant chemotherapy (AC) within urothelial carcinoma of the urinary bladder (UCUB) patients after radical cystectomy (RC) is under debate. We assessed contemporary AC utilization rates. We also examined the rates of AC according to patient disease and sociodemographic characteristics. We relied on the SEER-Medicare database for non-organ-confined, muscle-invasive T2 N+ -T4a UCUB patients who underwent RC between 1991 and 2009 without neoadjuvant chemotherapy delivery. Multivariable logistic regression analyses tested predictors of AC use; T-stage, N-stage, year of diagnosis, age, gender, race, radiotherapy (RT) administration, marital urban and socioeconomic status, tumor grade and Charlson Comorbidity Index (CCI). Overall, 2681 patients were identified. Of those, 667 (24.9%) received AC. The rate of AC were 21.4%, 23.5%, 24.6% and 29.9% over time (1991-1999 vs. 2000-2002 vs. 2003-2005 vs. 2006-2009) (P=0.002). In multivariable analyses stages pT2N+ (odds ratio (OR): 4.7; P<0.001) and pT3/4aN+ (OR: 4.0; P<0.001), year of diagnosis (OR: 1.9; P<0.001), RT (OR: 1.7; P<0.001), married status (OR: 1.4; P=0.001) and advanced age (OR: 0.3; P<0.001) were independent predictors of AC. Neither race nor CCI demonstrated significance. In conclusion, we report lower than anticipated overall (24.9%) use of AC. Nonetheless, the rate increased from 13.6% (1991) to 24.1% (2009). Presence of lymph node invasion at RC regardless of T2 or T3/4a stage was the most important variable that increased AC use. Older and unmarried individuals were less likely to receive AC. AC rates were higher in T2N+ UCUB patients than in T3-T4a individuals.

Background Nearly half of muscle-invasive bladder cancer patients succumb to their disease following cystectomy. Selecting candidates for adjuvant therapy is currently based on clinical parameters with limited predictive power. This study aimed to develop and validate genomic-based signatures that can better identify patients at risk for recurrence than clinical models alone. Methods Transcriptome-wide expression profiles were generated using 1.4 million feature-arrays on archival tumors from 225 patients who underwent radical cystectomy and had muscle-invasive and/or node-positive bladder cancer. Genomic (GC) and clinical (CC) classifiers for predicting recurrence were developed on a discovery set (n = 133). Performances of GC, CC, an independent clinical nomogram (IBCNC), and genomic-clinicopathologic classifiers (G-CC, G-IBCNC) were assessed in the discovery and independent validation (n = 66) sets. GC was further validated on four external datasets (n = 341). Discrimination and prognostic abilities of classifiers were compared using area under receiver-operating characteristic curves (AUCs). All statistical tests were two-sided. Results A 15-feature GC was developed on the discovery set with area under curve (AUC) of 0.77 in the validation set. This was higher than individual clinical variables, IBCNC (AUC = 0.73), and comparable to CC (AUC = 0.78). Performance was improved upon combining GC with clinical nomograms (G-IBCNC, AUC = 0.82; G-CC, AUC = 0.86). G-CC high-risk patients had elevated recurrence probabilities (P < .001), with GC being the best predictor by multivariable analysis (P = .005). Genomic-clinicopathologic classifiers outperformed clinical nomograms by decision curve and reclassification analyses. GC performed the best in validation compared with seven prior signatures. GC markers remained prognostic across four independent datasets. Conclusions The validated genomic-based classifiers outperform clinical models for predicting postcystectomy bladder cancer recurrence. This may be used to better identify patients who need more aggressive management. PMID:25344601

To examine the different and health-related quality of life (HR-QoL) outcomes between ileal conduit (IC) and ileal orthotopic neobladder (IONB) in patients who underwent radical cystectomy (RC), by using validated self-reported cancer-specific instruments. This retrospective, cross-sectional, multicenter cohort study included 148 and 171 patients with either IC or IONB. HR-QoL was evaluated with Quality of Life Core Questionnaire and bladder module (BLM)-30 European Organisation for Research and Treatment of Cancer questionnaires. Baseline HR-QoL scores were dichotomized at the median to give "good" or "poor" score profiles. A matched-pair analysis compared HR-QoL aspects between 79 IC patients and 79 IONB patients. At univariate analysis IONB resulted favorable for physical functioning, emotional functioning, cognitive functioning (CF), fatigue, dyspnea, appetite loss, constipation (CO), and abdominal bloating flatulence (AB). At multivariate analyses, IONB showed better scores for emotional functioning (85 vs 79, P = .023), CF (93 vs 85, P <.001), CO (16 vs 31, P <.001), and AB (12 vs 25, P <.001). A significant worsening of sexual and urinary function was observed for IONB patients in the long-term. At matched-pair analysis, global health status was similar (65 vs 62, P = .385). Significantly better scores were observed in the IONB group for the following items: CF (P = .007), fatigue (P = .003), pain (P = .019), dyspnea (P = .016), CO (P = .001), and AB (P = .00). IONB and IC after RC were similar in terms of global health status. IONB provides better results in some aspects of HR-QoL related to bowel function, but a worsening of urinary and sexual functions. Further randomized controlled trials are needed to confirm these data. Copyright © 2017 Elsevier Inc. All rights reserved.

Radical cystectomy with bilateral pelvic lymph node dissection is the standard of care for patients with clinically localized muscle-invasive bladder cancer. Survival after radical cystectomy is associated with final pathologic staging. Survival decreases with increasing pT stage because of the presence of occult micrometastases, indicating the need for systemic chemotherapy. Systemic chemotherapy is delivered as either neoadjuvant therapy preoperatively, or as adjuvant therapy postoperatively. This article reviews the evidence for neoadjuvant and adjuvant chemotherapy for the treatment of muscle-invasive bladder and upper tract urothelial cancer and offers recommendations based on these data and recently updated clinical guidelines.

New clinical trial open for patients with muscle-invasive bladder cancer | Center for Cancer Research

Cancer.gov

Muscle-invasive bladder cancer is an aggressive form of bladder cancer in which the tumor invades deep into the musculature of the bladder wall, making it more likely to spread to other parts of the body. Standard treatment involves cisplatin-based chemotherapy followed by radical cystectomy, which is surgery to remove the bladder and nearby organs. However, many patients don’t receive chemotherapy before surgery or may not respond to it. Other patients are ineligible for cisplatin treatment due to poor kidney function. CCR investigators are leading a phase III trial to determine whether an immunotherapy drug given shortly after cystectomy can help these patients. Read more…

Neurogenic bladder dysfunction has a negative impact on the patient's quality of life (QoL). Cystectomy with ileal conduit urinary diversion is a treatment option in patients in failure after conservative management. The objective of this study was to evaluate the impact of ileal conduit urinary diversion on the QoL of patients with neurogenic bladder dysfunction. From March 2004 to November 2010, 48 patients (36 women and 12 men with a mean age of 50.6  ±  11.8 years) treated by cystectomy with ileal conduit urinary diversion for neurogenic bladder dysfunction, prospectively completed, before and after surgery, two self-administered QoL questionnaires. Neurological diseases were multiple sclerosis in 38 cases, spinal cord injury in 7 cases, and other neurological disease in 3 cases. Cystectomy was performed by laparoscopy in all patients. QoL was measured by using two self-administered questionnaires, one questionnaire specific for urinary disorders validated in neurological patients, Qualiveen®, and the generic SF36-v2® questionnaire. Data were compared by Student's t test. Comparison of the Qualiveen® self-administered questionnaire scores and indices before and after surgery showed that, after surgery, patients presented a significant reduction of limitations (0.57 ± 0.64 vs. 1.55 ± 1.35, P < 0.001), constraints (2.12  ±  0.83 vs. 2.64  ±  1.12, P = 0.046) scores and the SIUP index (1.29 ± 0.65 vs. 1.79 ± 0.95, P = 0.015). No significant change in SF36-v2® scores was observed postoperatively. Ileal conduit urinary diversion improves the urinary QoL of patients with neurogenic bladder dysfunction by decreasing limitations and constraints induced by urinary disorders, but has no impact on general QoL.

External Validation and Optimization of International Consensus Clinical Target Volumes for Adjuvant Radiation Therapy in Bladder Cancer

DOE Office of Scientific and Technical Information (OSTI.GOV)

Reddy, Abhinav V.; Christodouleas, John P.; Wu, Tianming

Purpose: International consensus (IC) clinical target volumes (CTVs) have been proposed to standardize radiation field design in the treatment of patients at high risk of locoregional failure (LRF) after radical cystectomy. The purpose of this study was to externally validate the IC CTVs in a cohort of postsurgical patients followed up for LRF and identify revisions that might improve the IC CTVs' performance. Methods and Materials: Among 334 patients with pT3 to pT4 bladder cancer treated with radical cystectomy, LRF developed in 58 (17%), of whom 52 had computed tomography scans available for review. Images with LRF were exported intomore » a treatment planning system, and IC CTVs were contoured and evaluated for adequacy of coverage of each LRF with respect to both the patient and each of 6 pelvic subsites: common iliac (CI) region, obturator region (OR), external and internal iliac region, presacral region, cystectomy bed, or other pelvic site. Revisions to the IC contours were proposed based on the findings. Results: Of the 52 patients with documented LRF, 13 (25%) had LRFs that were outside of the IC CTV involving 17 pelvic subsites: 5 near the CI CTV, 5 near the OR CTV, 1 near the external and internal iliac region, and 6 near the cystectomy bed. The 5 CI failures were located superior to the CTV, and the 5 OR failures were located medial to the CTV. Increasing the superior boundary of the CI to a vessel-based definition of the aortic bifurcation, as well as increasing the medial extension of the OR by an additional 9 mm, decreased the number of patients with LRF outside of the IC CTV to 7 (13%). Conclusions: Modified IC CTVs inclusive of a slight adjustment superiorly for the CI region and medially for the OR may reduce the risk of pelvic failure in patients treated with adjuvant radiation therapy.« less

Validating a Local Failure Risk Stratification for Use in Prospective Studies of Adjuvant Radiation Therapy for Bladder Cancer

DOE Office of Scientific and Technical Information (OSTI.GOV)

Baumann, Brian C.; He, Jiwei; Hwang, Wei-Ting

Purpose: To inform prospective trials of adjuvant radiation therapy (adj-RT) for bladder cancer after radical cystectomy, a locoregional failure (LF) risk stratification was proposed. This stratification was developed and validated using surgical databases that may not reflect the outcomes expected in prospective trials. Our purpose was to assess sources of bias that may affect the stratification model's validity or alter the LF risk estimates for each subgroup: time bias due to evolving surgical techniques; trial accrual bias due to inclusion of patients who would be ineligible for adj-RT trials because of early disease progression, death, or loss to follow-up shortlymore » after cystectomy; bias due to different statistical methods to estimate LF; and subgrouping bias due to different definitions of the LF subgroups. Methods and Materials: The LF risk stratification was developed using a single-institution cohort (n=442, 1990-2008) and the multi-institutional SWOG 8710 cohort (n=264, 1987-1998) treated with radical cystectomy with or without chemotherapy. We evaluated the sensitivity of the stratification to sources of bias using Fine-Gray regression and Kaplan-Meier analyses. Results: Year of radical cystectomy was not associated with LF risk on univariate or multivariate analysis after controlling for risk group. By use of more stringent inclusion criteria, 26 SWOG patients (10%) and 60 patients from the single-institution cohort (14%) were excluded. Analysis of the remaining patients confirmed 3 subgroups with significantly different LF risks with 3-year rates of 7%, 17%, and 36%, respectively (P<.01), nearly identical to the rates without correcting for trial accrual bias. Kaplan-Meier techniques estimated higher subgroup LF rates than competing risk analysis. The subgroup definitions used in the NRG-GU001 adj-RT trial were validated. Conclusions: These sources of bias did not invalidate the LF risk stratification or substantially change the model's LF estimates.« less

To elucidate the differences in clinical practice between the USA and Japan in major types of uro-oncological surgery by a head-to-head comparison of national databases in the two countries. We compared variations in surgical modality, length of stay, total charges, caseload centralization, transfusion incidence, and in-hospital mortality between the two countries for four major types of uro-oncological surgery (radical prostatectomy, radical cystectomy, nephrectomy and nephroureterectomy) in 2011. Additionally, the chronological changes in surgical modalities were investigated for 2009-11. The national estimates were based on data from the Japanese Diagnosis Procedure Combination database and the US National Inpatient Sample. For radical prostatectomy, radical cystectomy, nephrectomy and nephroureterectomy, minimally-invasive surgery accounted for 24.2% versus 70.2%, 0% versus 14.0%, 50.7% versus 30.7% and 50.2% versus 30.5%, respectively, in Japan versus the USA in 2011. Although minimally-invasive surgery has become increasingly frequent in both countries, the major procedures were robot-assisted surgery in the USA and laparoscopic surgery in Japan. The USA was generally characterized by a slightly younger age at operation, far higher hospital volume, a shorter length of stay, higher charges and less use of transfusion than Japan. The findings suggest substantial differences between the USA and Japan regarding clinical practices in uro-oncological surgery. Standing at the beginning of robotic surgery era in Japan, the precise recognition of these differences will aid a proper understanding of clinical practices. © 2014 The Japanese Urological Association.

Peritoneal mucinous cystadenocarcinoma of probable urachal origin: a challenging diagnosis

This report describes the case of a mucinous cystadenocarcinoma of probable urachal origin that presented with mass effect, precipitating deep venous thrombosis and pulmonary embolism. The patient presented with acute symptoms of leg swelling, pain and dyspnoea, and a vague awareness of lower abdominal distension. Computer tomography showed a cystic mass closely related to the anterior abdominal wall and the superior aspect of the bladder. A 1500 cm3 cyst adherent to the dome of the urinary bladder was resected on laparotomy. Partial cystectomy was not carried out in the belief that the cyst represented a benign lesion. Subsequent imaging has shown cystic changes in the anterior bladder wall, and the patient has been referred for partial cystectomy. PMID:17021133

In renal transplant recipients, the risk of developing bladder cancer and rate of diagnosis of advanced staged bladder cancer are generally higher than the general population. Also, it is more challenging to treat renal transplant recipients than the regular patient population. We aimed to evaluate the efficacy and safety of radical cystectomy (RC) and urinary diversion with ileal conduit in renal transplant recipients. We identified 2 patients with prior history of renal transplantation who underwent RC and ileal conduit urinary diversion for bladder cancer. Preoperative clinical and demographic data were presented and outcomes were assessed. The RC and ileal conduit urinary diversion were performed in the first patient 56 months after renal transplantation and in the second patient 64 months after renal transplantation. Clinical staging was high-grade T2 transitional cell cancer of the bladder for patient 1 and T2 with pure squamous cell cancer of the bladder for patient 2. No perioperative or postoperative complication and no graft dysfunction occurred in either patient. Our experience demonstrated that RC with ileal conduit reconstruction in renal transplant recipients is safe and feasible. Copyright © 2016 Elsevier Inc. All rights reserved.

We report our experience of transumbilical single port laparoscopic surgery (TUSPLS) for multiple concomitant intraabdominal pathologies, and assess the feasibility of this technique with several technical tips. Various combined procedures using TUSPLS were performed since April, 2008. All records of concomitant laparoscopic procedures using TUSPLS were searched at three hospitals. Forty-one patients underwent 82 combined procedures using TUSPLS in a single session. The perioperative outcomes of simultaneously performed cholecystectomy and ovarian cystectomy using TUSPLS (n = 14) are compared with those of using CLS (n = 11). The operating time was significantly longer with the TUSPLS method than with the CLS method. However, postoperative convalescent outcomes such as postoperative hospital stay, VAS pain score, and required analgesics showed no differences between the two methods. Also, there were no significant operative complications associated with the two methods. Fewer trocars were used with the TUSPLS method. Combined laparoscopic procedures for various concomitant pathologies in the abdomen can be performed using transumbilical single port laparoscopic surgery without increasing morbidity or hospital stay in patients with acceptable risk.

To report on the safety and efficacy of rectus sheath blocks, 'topped-up' using bilateral rectus sheath catheters (RSCs), in patients undergoing major open urological surgery. The RSCs were inserted under ultrasound guidance into 200 patients between April 2008 and August 2011, of whom 106 patients underwent radical retropubic prostatectomy (RRP) and 94 underwent open radical cystectomy (ORC). A retrospective case-note review was undertaken. Outcomes included technical success and complication rates of the insertion and use of RSC, visual analogue pain scores, additional analgesia requirements and length of hospital stay (LOS). All RSCs were successfully placed without complication and used for a mean of 3.6 days for ORC and 2.1 days for RRP. Early removal occurred in 6.49% of patients. Low overall pain scores were reported in both groups. Patients were more likely to require a patient-controlled analgesia system in the ORC group but the overall need for additional analgesia was low in both groups, reducing significantly after the initial 24 h. In combination with an enhanced recovery programme, LOS reduced from 17.0 to 10.8 days in the ORC group and from 6.2 to 2.8 days in the RRP group. The use of RSCs appears to offer an effective and safe method of peri-operative analgesia in patients undergoing major open urological pelvic surgery. © 2013 The Authors.

2018-07-01

To analyze the feasibility and perioperative results of patients undergoing robot-assisted cystectomy with intracorporeal urinary diversion and robot-sewn ileoileal anastomosis. This is a mono-centric analysis of perioperative data from 48 consecutive patients undergoing robot-assisted cystectomy with intracorporeal urinary diversion and robot-sewn ileoileal anastomosis. Data include the preoperative variables, operative and postoperative course and complication rates related to bowel anastomosis. End points were time spent for anastomosis and intra- and postoperative complication rates. Median operating time was 23.0 (13-60) min for the ileoileal anastomosis. Median overall operating time was 295 (200-780) min, with a median of 282 (200-418) min and 414.0 (225-780) min for the ileum conduit (N = 35) and ileal neobladder (N = 13). Two patients developed paralytic ileus; in another patient acute peritonitis occurred, but was caused by urinary leakage and therefore unrelated to the bowel anastomosis. No anastomotic leakage was noticed. Costs for the robot-sewn anastomosis was 8€ compared to 1250€ for a stapled anastomosis which was performed in previous cases. Limitations are the non-comparative nature of the analysis and the limited number of patients. Robot-sewn ileoileal anastomosis is feasible with low complication rates. Compared to the stapled anastomosis, a robot-sewn ileoileal anastomosis may serve as an alternative and cost-saving approach.

Radical cystectomy (RC) is a morbid procedure with frequent complications that may benefit from implementation of an enhanced recovery after surgery (ERAS) protocol. To examine the benefits of a multimodal analgesic plan that uses continuous transversus abdominis plane (TAP) blockade as part of an ERAS protocol after RC. A retrospective comparison of consecutive patients undergoing RC over a 4-year period was conducted. Patients were designated as having surgery either before or after implementation of an ERAS protocol. A major component of the ERAS protocol was a multi-modal analgesia plan with TAP blockade. Patient demographics, comorbidities, operative details, and outcomes, including days to flatus, bowel movement (BM), narcotic usage, and length of stay (LOS) were compared. In total, 171 patients were included: 100 pre-ERAS and 71 ERAS. There were no differences in age, smoking status, operative approach, or diversion type. The patients in the ERAS cohort were less likely to be male, had a higher median BMI, and more likely to have received neoadjuvant chemotherapy. Total and early postoperative narcotic use were lower in the ERAS cohort: 89 vs. 336 mg ( p  < 0.001) and 62 vs 203 mg ( p  = 0.001), respectively. The ERAS cohort had fewer days to flatus (3 vs. 4, p  < 0.001) and fewer days to bowel movement (4 vs. 5, p  < 0.001). Median LOS was shorter in the ERAS cohort (7 vs. 8.5d, p  = 0.001). There were no differences in complications or readmission rates between the two cohorts. TAP blockade as part of an ERAS multi-modal pain plan is associated with low narcotic usage, and significant improvement in time to flatus, BM, and LOS compared to traditional post-RC pain management.

Study Type-Prognosis (cohort) Level of Evidence 2a. What's known on the subject? and What does the study add? Radical cystectomy with pelvic lymph node dissection is recognized as the standard of care for carcinoma invading bladder muscle and for refractory non-muscle-invasive bladder cancer. Owing to high recurrence and progression rates, a two-pronged strict surveillance regimen, consisting of both functional and oncological follow-up, has been advocated. It is also well recognized that more aggressive tumours with extravesical disease and node-positive disease recur more frequently and have worse outcomes. This study adds to the scant body of literature available regarding surveillance strategies after radical cystectomy for bladder cancer. In the absence of any solid evidence supporting the role of strict surveillance regimens, this extensive examination of recurrence patterns in a large multi-institutional project lends further support to the continued use of risk-stratified follow-up and emphasizes the need for earlier strict surveillance in patients with extravesical and node-positive disease. To review our data on recurrence patterns after radical cystectomy (RC) for bladder cancer (BC). To establish appropriate surveillance protocols. We collected and pooled data from a database of 2287 patients who had undergone RC for BC between 1998 and 2008 in eight different Canadian academic centres. Of the 2287 patients, 1890 had complete recurrence information and form the basis of the present study. A total of 825 patients (43.6%) developed recurrence. According to location, 48.6% of recurrent tumours were distant, 25.2% pelvic, 14.5% retroperitoneal and 11.8% to multiple regions such as pelvic and retroperitoneal or pelvic and distant. The median (range) time to recurrence for the entire population was 10.1 (1-192) months with 90 and 97% of all recurrences within 2 and 5 years of RC, respectively. According to stage, pTxN+ tumours were more likely to recur than p ≥ T3N0 tumours and p ≤ T2N0 tumours (5-yr RFS 25% vs. 44% vs. 66% respectively, P < 0.001). Similarly, pTxN+ tumours had a shorter median time to recurrence (9 months, range 1-72 months) than p ≥ T3N0 tumours (10 months, range 1-70 months) or p ≤ T2N0 tumours (14 months, range 1-192 months, P < 0.001). Differences in recurrence patterns after RC suggest the need for varied follow-up protocols for each group. We propose a stage-based protocol for surveillance of patients with BC treated with RC that captures most recurrences while limiting over-investigation. Copyright © 2013. Published by Elsevier Inc.

Intraventricular Neurocysticercosis: Experience and Long-Term Outcome from a Tertiary Referral Center in the United States.

2018-04-23

Ventricular involvement in neurocysticercosis (NCC), a common serious manifestation of NCC, has distinct clinical presentations, complications, and treatments primarily because of partial or complete obstruction of the cerebrospinal fluid (CSF) flow by Taenia solium cysts. We review the clinical course, treatments, and long-term outcomes in 23 of 121 (19.0%) total NCC patients with ventricular cysts referred to the National Institutes of Health from 1985 to the October 2017. Patients had a median age of 31.8 (range: 22.4-52.6 years), were 60.9% male, diagnosed a median of 6.5 years (range: 0.17-16 years) after immigration, and were followed for a median of 3.6 years (range: 0.1-30.5 years). Other forms and manifestations of NCC were present in 73.9% (17/23). The fourth ventricle was involved in a majority (15/23, 65.2%) resulting in hydrocephalus (73.9%), ventriculitis, and periventricular edema (7/23, 30.4%). Cystectomy was accomplished in 60.9%, usually by removal of a fourth ventricular cyst through a suboccipital craniotomy. Nonresectable cysts were treated medically. Ventriculoperitoneal shunts were inserted in 43.5% (10/23) and failed in four, three from infection. Other complications included surgically induced injuries (4/23, 17.4%) and entrapment of a lateral ventricle (2/23, 8.7%). Despite a common severe early course, 90.9% (20/22) stabilized without recurrence, 15% (3/20) complained of mild-to-moderate neurological complaints, and 15% (3/20) were significantly disabled. Four patients who underwent removal of ventricular cysts without significant other NCC and who received with no cysticidal treatment became CSF cestode antigen negative without recurrence indicating that after successful extraction of cysts, additional cysticidal treatment may not be needed.

We sought to investigate the safety and efficacy of gemcitabine, cisplatin, and lapatinib (GCL) as neoadjuvant therapy in patients with muscle-invasive bladder cancer (MIBC) planned for radical cystectomy. Four cycles of GCL were administered as neoadjuvant therapy for patients with MIBC. Although initially designed as a phase II efficacy study with a primary endpoint of pathologic complete response at the time of radical cystectomy, the dose selected for investigation proved excessively toxic. A total of six patients were enrolled. The initial four patients received gemcitabine 1,000 mg/m(2) intravenously on days 1 and 8 and cisplatin 70 mg/m(2) intravenously on day 1 of each 21-day treatment cycle. Lapatinib was administered as 1,000 mg orally daily starting one week prior to the initiation of cycle 1 of gemcitabine and cisplatin (GC) and continuing until the completion of cycle 4 of GC. These initial doses were poorly tolerated, and the final two enrolled patients received a reduced lapatinib dose of 750 mg orally daily. However, reduction of the lapatinib dose did not result in improved tolerance or drug-delivery, and the trial was terminated early due to excessive toxicity. Grade 3/4 toxicities included diarrhea (33%), nausea/vomiting (33%), and thrombocytopenia (33%). The addition of lapatinib to GC as neoadjuvant therapy for MIBC was limited by excessive treatment-related toxicity. These findings highlight the importance of thorough dose-escalation investigation of combination therapies prior to evaluation in the neoadjuvant setting, as well as the limitations of determination of maximum tolerated dose for novel targeted combination regimens.

Although improvements in perioperative care have decreased surgical morbidity after radical cystectomy for muscle invasive bladder cancer, treatment side effects still have a negative impact on patient quality of life. We examined unmet patient needs along the illness trajectory. A total of 30 patients (26.7% women) treated with cystectomy and urinary diversion for muscle invasive bladder cancer participated in the study. Patients were recruited from the Department of Urology at Mount Sinai and through advertisements on the Bladder Cancer Advocacy Network (BCAN) website between December 2011 and September 2012. Data were collected at individual interviews, which were audiotaped and transcribed. Transcribed data were quantitatively analyzed to explore key unmet needs. At diagnosis unmet informational needs were predominant, consisting of insufficient discussion of certain topics, including urinary diversion options and their side effects, self-care, the recovery process and medical insurance. Unmet psychological needs related to depression, and worries about changes in body image and sexual function were reported. Postoperative unmet needs revolved around medical needs (eg pain and bowel dysfunction) and instrumental needs (eg need of support for stomal appliances, catheters and incontinence). During survivorship (ie 6 to 72 months postoperatively) unmet needs centered around psychological support (ie depression, poor body image and sexual dysfunction) and instrumental support (eg difficulty adjusting to changes in daily living). Meeting patient needs is imperative to ensure adequate patient involvement in health care and enhance postoperative quality of life. An effective support provision plan should follow changes in patient needs. Copyright © 2014 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

Adjuvant radiation therapy for bladder cancer: A dosimetric comparison of techniques

DOE Office of Scientific and Technical Information (OSTI.GOV)

Baumann, Brian C.; Noa, Kate; Wileyto, E. Paul

Trials of adjuvant radiation after cystectomy are under development. There are no studies comparing radiation techniques to inform trial design. This study assesses the effect on bowel and rectal dose of 3 different modalities treating 2 proposed alternative clinical target volumes (CTVs). Contours of the bowel, rectum, CTV-pelvic sidewall (common/internal/external iliac and obturator nodes), and CTV-comprehensive (CTV-pelvic sidewall plus cystectomy bed and presacral regions) were drawn on simulation images of 7 post-cystectomy patients. We optimized 3-dimensional conformal radiation (3-D), intensity-modulated radiation (IMRT), and single-field uniform dose (SFUD) scanning proton plans for each CTV. Mixed models regression was used to comparemore » plans for bowel and rectal volumes exposed to 35% (V{sub 35%}), 65% (V{sub 65%}), and 95% (V{sub 95%}) of the prescribed dose. For any given treatment modality, treating the larger CTV-comprehensive volume compared with treating only the CTV-pelvic sidewall nodes significantly increased rectal dose (V{sub 35%} {sub rectum}, V{sub 65%} {sub rectum}, and V{sub 95%} {sub rectum}; p < 0.001 for all comparisons), but it did not produce significant differences in bowel dose (V{sub 95%} {sub bowel}, V{sub 65%} {sub bowel}, or V{sub 35%} {sub bowel}). The 3-D plans, compared with both the IMRT and the SFUD plans, had a significantly greater V{sub 65%} {sub bowel} and V{sub 95%} {sub bowel} for each proposed CTV (p < 0.001 for all comparisons). The effect of treatment modality on rectal dosimetry differed by CTV, but it generally favored the IMRT and the SFUD plans over the 3-D plans. Comparison of the IMRT plan vs the SFUD plan yielded mixed results with no consistent advantage for the SFUD plan over the IMRT plan. Targeting a CTV that spares the cystectomy bed and presacral region may marginally improve rectal toxicity but would not be expected to improve the bowel toxicity associated with any given modality of adjuvant radiation. Using the IMRT or the SFUD plans instead of the 3-D conformal plan may improve both bowel and rectal toxicity.« less

To evaluate the effect of a smoking-, alcohol- or combined-cessation intervention starting shortly before surgery and lasting 6 weeks on overall complications after radical cystectomy. Secondary objectives are to examine the effect on types and grades of complications, smoking cessation and alcohol cessation, length of hospital stay, health-related quality of life and return to work or habitual level of activity up to 12 months postoperatively. The study is a multi-institutional randomised clinical trial involving 110 patients with a risky alcohol intake and daily smoking who are scheduled for radical cystectomy. Patients will be randomised to the 6-week Gold Standard Programme (GSP) or treatment as usual (control). The GSP combines patient education and pharmacologic strategies. Smoking and alcohol intake is biochemically validated (blood, urine and breath tests) at the weekly meetings and at follow-up. Herein, we report the design of the STOP-OP study, objectives and accrual up-date. This study will provide new knowledge about how to prevent smoking and alcohol-related postoperative complications at the time of bladder cancer surgery. Till now 77 patients have been enrolled. Patient accrual is expected to be finalised before the end of 2017 and data will be published in 2018. ClinicalTrials.gov, ID: NCT02188446 . Registered on 28 May 2014.

To describe the tolerability of two chemotherapy regimens, gemcitabine and cisplatin (GC) and methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) for adjuvant treatment of patients with locally advanced urothelial cancer after radical cystectomy. The USC Department of Urology bladder cancer database was searched for subjects who received adjuvant chemotherapy following cystectomy for transitional cell carcinoma with extravesical and/or lymph node involvement, yielding 187 cases. Clinical details regarding toxicity, number of cycles administered, and cancer outcome were analyzed. The majority of subjects had lymph node involvement (70%). Sixty-eight percent of subjects received MVAC and 32% received GC, the latter regimen was predominant after 2000. Fifty-six percent of subjects received all four planned cycles (51% GC and 58% MVAC). With a median follow-up of 11.2 years (range 1.9-19.6), 96 patients (51%) have suffered a relapse, with no significant difference between chemotherapy regimens. Median time to recurrence for the population was 3.7 years and median overall survival is 4.6 years (3.0-9.3). The median time from recurrence to death was 6.7 months and was not significantly different between MVAC and GC. Both MVAC and GC are tolerated after cystectomy for advanced urothelial carcinoma. A significant proportion of high-risk patients survive, free of disease, beyond 10 years. At recurrence, patients previously treated with adjuvant chemotherapy have a survival that appears much shorter than patients who develop metastases in the absence of this exposure, suggesting resistance to salvage chemotherapy.

To identify and review cases of isolated fallopian tube torsion (FTT) at our institution to further characterize diagnosis and management. Retrospective review. Tertiary care medical center. Case series of pediatric and adolescent females, <21 years old, with operatively diagnosed isolated fallopian tube torsion from our institution. None. Isolated fallopian tube torsion. Fifteen cases of isolated fallopian tube torsion were identified based on intraoperative diagnosis. Patient ages ranged from 8-15 years old, mean age of 12. Fourteen patients (93%) presented with abdominal pain, 8 (53%) localized to the side of associated torsion. Ultrasonography reports described a tubular structure in 4 patients and an associated ovarian or paraovarian cyst in eleven patients. Suspicion of fallopian tube torsion was only described for those patients with a tubular structure described on ultrasonography report. Intraoperatively, 7 patients (47%) were found to have no associated pathology and 8 (53%) were found to have associated cyst or hydrosalpinx. Eight (53%) patients underwent salipingectomy and 7 (47%) underwent reversal of torsion with drainage of associated cyst or cystectomy. Isolated fallopian tube torsion is a rare condition that seems to occur in younger adolescents. Vague clinical presentation contributes to low preoperative suspicion. Preoperative suspicion may be increased based on radiographic findings of an enlarged tubular structure or an adjacent normal ovary. Management may be considered nonemergent and salpingectomy is controversial. Long-term fertility outcomes must be further assessed for more definitive decisions regarding surgical management.

Background and Objective: Deep infiltrating pelvic endometriosis with bowel involvement is one of the most aggressive forms of endometriosis. Nowadays, robotic technology and telemanipulation systems represent the latest developments in minimally invasive surgery. The aim of this study is to present our preliminary results and evaluate the feasibility of robotic-assisted laparoscopic colorectal resection for severe endometriosis. Methods: Between September 2009 and December 2011, 10 women with colorectal endometriosis underwent surgery with the da Vinci robotic surgical system (Intuitive Surgical, Sunnyvale, CA, USA). We evaluated the following parameters: short-term complications, clinical outcomes and long-term follow-up, pain relief recurrence rate, and fertility outcomes. Results: Extensive ureterolysis was required in 8 women (80%). Ovarian cystectomy with removal of the cystic wall was performed in 7 women (70%). Torus resection was performed in all women, with unilateral and bilateral uterosacral ligament resection in 1 woman (10%) and 8 women (80%), respectively. In addition to segmental colorectal resection in all cases, partial vaginal resection was necessary in 2 women (20%). An appendectomy was performed in 2 patients (20%). The mean operative time with the robot was 157 minutes (range, 90–190 minutes). The mean hospital stay was 3 days. Six patients had infertility before surgery, with a mean infertility time of 2 years. After a 12-month follow-up period, 4 women (67%) conceived naturally and 2 (33%) underwent in vitro fertilization. Conclusion: We show that robotic-assisted laparoscopic surgery for the treatment of deep infiltrating bowel endometriosis is feasible, effective, and safe. PMID:23925016

86 cases of solitary air cysts of the lung (6.83% of all maldevelopments) were analyzed. This maldevelopment of bronchial tree is found most often in men (10:7) and more often in the right lung than in the left (18:13). There were no clinical symptoms in 33 (38.37%) patients. Uncomplicated course of the disease was in 51 (59.3%) patients, the disease was complicated by infection in 28 (32.56%) patients. Solitary bronchial cysts were complicated by spontaneous pneumothorax in 8.14% cases, by hemoptysis--in 6.98%. Roentgenography of the chest thorax on two projections and tomography (including CT) are enough for diagnosis of solitary air bronchial cysts. Bronchoscopy, bronchography and APG are not much informative in diagnosis of cysts and should be used on special indications. Cystectomy or cystectomy with partial resection of lung tissue were performed in 67.14% patients with good results.

Ileal conduit remains a widely used urinary diversion performed after radical cystectomy. However, complications of ileal conduits remain an important concern in urological surgery. We report a rare case of an ileal conduit stricture, which can have grim complications if unobserved during the operation. Following an initial operation of radical cystectomy and ileal conduit formation in France in 2011, an 80-year-old male travelled back to the UK after 4 months of general weakness and limb paralysis. Initial blood test shows life-threatening hyperkalemia and worsened renal function. Subsequent ultrasound KUB scan and loopogram revealed obstructive uropathy. The initial management includes intravenous antibiotics and bilateral nephrostomies were inserted to aid diversion of urine. A thorough surgical exploration revealed a twisted, fibrous mesenteric band adhered to the proximal part of the ileal conduit. Only one case report of ileal conduit stenosis was described many years after the procedure. PMID:24963928

Diagnostic imaging was inconclusive, describing a giant cystic formation that filled up the abdomen, but without specifying its origin. Laboratory tests and tumor markers were within normal range. Video-assisted transumbilical cystectomy, a modified laparoscopic procedure with diagnostic and therapeutic intent, was performed with a successful outcome. The histological study reported giant paraovarian cyst. Cytology results were negative for tumor cells. The patient remained asymptomatic during the postoperative follow-up. The video-assisted transumbilical cystectomy is a safe procedure and an excellent diagnostic and therapeutic alternative for the treatment of giant paraovarian cysts. Copyright © 2015.

Objective Surgical stress combined with general anaesthesia (GA) suppresses the immune system and leads to cancer cell growth and premature metastasis in major oncological interventions. Epidural analgesia decreases the need for inhalation agents and opioids during surgery by suppressing sympathetic and neuroendocrine responses in the postoperative period. This study aimed to compare the effects of combined general/epidural anaesthesia (GEA)+patient-controlled epidural analgesia (PCEA) and GA+IV patient-controlled analgesia (PCA) on serum tumour necrosis factor-alpha TNF-α), interleukin-1 beta (IL-1β) and interferon-gamma (IFN-γ) levels in patients undergoing radical cystectomy. Methods Sixty-five patients were enrolled in this prospective study. Patients were randomly enrolled to the GEA group, i.e., combined GEA+ PCEA (0.1% bupivacaine+1 μg mL−1 fentanyl), and the GA group, namely combined GA+IV PCA (0.03 mg mL−1 morphine). To evaluate the cytokine response, blood samples were collected at preoperative, postoperative 1st and 24th hours. Results There was no statistically significant difference in serum TNF-α, IL-1β and IFN-γ levels between groups GA and GEA at preoperative and postoperative 1st hour and 24th hour. Total remifentanil consumption was significantly lower and length of hospital stay was significantly shorter in the GEA group than in the GA group (p<0.05). Conclusion There is no difference between two anaesthesia methods in terms of serum cytokine levels; however, combined GEA+PCEA technique appeared to be superior to GA+IV PCA because of lower intraoperative narcotic analgesic consumption and shorter hospital stay.

We evaluated the diagnostic accuracy of urinary cytology (UCy) for detecting recurrence in the remnant urothelium (RRU) after radical cystectomy (RC) for urothelial cancer. We conducted a 10-year retrospective analysis of a prospectively collected, single-center RC database comprising 177 patients who had undergone follow-up examinations at our department with ≥ 1 available postoperative UCy specimen. UCy specimens were classified using the Papanicolaou scheme. In total, 957 cytology specimens were collected. Negative UCy results were noted in 927 (96.8%), atypical urothelial cells in 19 (2.0%), and suspicious/positive for malignancy in 11 (1.2%) cases. RRU was diagnosed in 16 patients (9.1%) during a mean follow-up period of 37 months (range, 1-118 months). The mean interval from RC to RRU was 34.7 months. Only 2 of 11 positive UCy specimens (18.2%) were falsely positive, for an overall sensitivity and specificity of 56.3% and 98.8% for predicting RRU, respectively. Urethral recurrence was diagnosed by UCy alone before the patients had developed symptoms in 8 of 12 cases (66.7%). Patients with clinical symptoms at the diagnosis of RRU had poorer cancer-specific survival rates than those of asymptomatic patients, although this trend was not statistically significant (P = .496). Moreover, positive UCy findings were associated with significantly lower overall survival (P < .001) and cancer-specific survival (P = .04) compared with negative UCy findings. Our results underline the predictive value of UCy in the surveillance of the remnant urothelium, with early detection of urethral recurrence before the development of clinical symptoms.

Hospital surgical volume has been shown to correlate with short-term outcomes after cancer surgery, but the relationship between volume and cost of care is unclear. We sought to characterize variation in payments for cancer surgery and assess the relationship between hospital volume and payments. Using 2000 to 2007 Surveillance, Epidemiology, and End Results-Medicare data, we assessed risk-adjusted 30-day episode Medicare payments for elderly patients undergoing one of six procedures for resection of cancer. Payments for the index hospitalization, readmissions, physician services, emergency room visits, and postdischarge ancillary care were analyzed, as were data on 30-day mortality and complications. The analysis included 31,191 colectomies, 2,670 cystectomies, 1,514 pancreatectomies, 2,607 proctectomies, 12,228 prostatectomies, and 10,151 pulmonary lobectomies. There was substantial variation in cost; differences between the first and third terciles of cost varied from 27% for cystectomy to 40% for colectomy. The majority of variation (66% to 82%) was attributable to payments for the index admission rather than readmissions or physician services. There were no meaningful associations between total risk-adjusted payments and hospital volume. Surgical mortality was low, but complication rates ranged from 10% (prostatectomy) to 56% (lobectomy). Complication rates were not correlated with hospital volume, but occurrence of complications was associated with 47% to 70% higher costs. We found substantial variation in Medicare payments for these six cancer procedures. Cost was strongly associated with postoperative complications and primarily driven by differences in the cost of the index hospitalization. Efforts to prevent and cost-effectively manage complications are more likely to reduce costs than volume-based referral of cancer surgery alone. © 2014 by American Society of Clinical Oncology.

Metastatic Urothelial Carcinoma with Glandular Differentiation That Confirmed the Response by Autopsy Specimen to Second-Line mFOLFOX6 (Fluorouracil, Oxaliplatin, and Leucovorin) plus Bevacizumab Chemotherapy

The prognostic significance of glandular differentiation in urothelial carcinoma (UC) is controversial, and thus far there is no established treatment strategy against metastasis of glandular component. We describe here a case of metastatic UC with glandular differentiation that had histological disappearance of adenocarcinoma components at autopsy after sequential chemotherapy with S-1 and cisplatin (CDDP) and with mFOLFOX6 (fluorouracil, oxaliplatin, and leucovorin) plus bevacizumab (mFOLFOX6+Bev). A 62-year-old Asian male was diagnosed with invasive UC with glandular differentiation (T2N0M0) by radical cystectomy and ileal conduit, and careful follow-up observation was made. Eight years after radical operation, peritoneal metastases occurred, and a biopsy specimen using colon fiber revealed high-grade adenocarcinomas with an immunohistochemical profile that included positivity for cytokeratin 7 (CK7) and negativity for cytokeratin 20 (CK20) and uroplakin, which was identical to the radical cystectomy specimen. Thus, he received combination chemotherapy consisting of S-1 and CDDP; however, the peritoneal metastasis worsened after 2 cycles. Therefore, second-line mFOLFOX6+Bev chemotherapy was performed for a total of 5 courses. In spite of this, the patient died, and the final diagnosis by autopsy was multiple metastases of infiltrating pure UC to the lung, bone, and peritoneum. Interestingly, there were no pathological findings of adenocarcinoma, and the immunohistochemical profile of the metastatic lesions was identical to that of the previous specimens from the bladder and colon. This suggests that sequential chemotherapy of S-1 and CDDP and second-line mFOLFOX6+Bev might be a feasible option in metastatic UC with glandular differentiation. PMID:29515396

• To systematically review and compare the economic burden of open radical cystectomy (ORC) vs robot-assisted laparoscopic radical cystectomy (RALRC) with pelvic lymph node dissection and urinary diversion. • A Medline search was conducted to identify English language articles regarding RC with urinary diversion. The resulting articles were then further restricted by the terms 'laparoscopic', 'robotic', or 'robotic-assisted'.In all, three articles were identified. • Data from each of these articles were then collected on cost performance in addition to relevant clinical variables, such as length of stay (LOS), operative duration, and complication rates. • When possible, data were subdivided by ileal conduit (IC), continent cutaneous diversion (CCD), and orthotopic neobladder (ON) subgroups. • Direct costs resulting from ORC or RALRC with accompanying hospitalization were identified. The indirect costs of complications were considered. • Despite an increased materials cost, RALRC was less expensive than ORC when the cost of complications was considered. • RALRC was less expensive than ORC for IC and CCD, but the cost advantage deteriorated for ON. • The largest cost drivers cited in the published data were LOS, operative durations, and daily hospitalizations costs. • RALRC demonstrated shorter LOS compared with ORC, although this effect was insufficient to offset the increased cost of robotic surgery. • Complications materially affected cost performance. • Despite an increased materials cost, RALRC can be more cost efficient than ORC as a treatment for bladder cancer when the impact of complications are considered. • This effect is most pronounced for patients undergoing IC. © 2011 THE AUTHORS.

We retrospectively assessed our experience with the W-shaped orthotopic ileal pouch, which was constructed with non-absorbable titanium staples. For these purpose, we discuss the results of bladder capacity, urinary continence and early and long-term postoperative complications. We included in the study 17 patients who underwent radical cystoprostatectomy followed by construction of an orthotopic W-shaped ileal pouch between October 2000 and November 2009. A 65-70 cm segment of ileum was isolated and prearranged into a W-configuration, leaving two 10 cm intact segments on both sides of the ileal fragment. In our technique we entirely anatomized all adjacent limbs in order to create a sphere-shaped pouch. The ureters were directly anastomized to both intact segments of the ileal division. All our patients underwent pouchscopy 6 months after operation and annually. Mean operative time for neobladder reconstruction and ureteral anastomoses was 87 ± 7.67 minutes. In one patient a leak from the ileo-ileal anastomosis was confirmed on the 3rd day after operation. In 2 cases unilateral stricture of the ureteral-neobladder anastomosis was documented. Staple lines were mostly covered with ileal mucosa after 6 months. The mean functional bladder capacity was 340 ± 27.6 mL and 375 ± 43.4 mL at 6 and 12 months, respectively. First-year daytime and nighttime continence was good and acceptable in 90% and 78% of patients, while it increased to 95% during the 2nd year. The long term follow-up shows that non-absorbable titanium staples can be safely used for creation of an orthotopic ileal neobladder. However, these data should be further validated in a larger series of patients.

To identify occult metastases within lymph nodes (LNs) reported as negative by routine histologic evaluation. In patients with high-grade, muscle-invasive urothelial carcinoma (UC) of the bladder, pelvic lymphadenectomy during radical cystectomy demonstrates a survival advantage, increasing with the number of LNs removed, even if negative for metastatic disease. This finding may potentially be explained by the presence of occult metastases. Radical cystectomy specimens with high-grade UC invading the perivesical tissue and negative LNs (pT3N0) between 2000 and 2014 were reviewed. Five levels were cut for each LN block. Two sections were cut per level: 1 stained for hematoxylin and eosin and 1 for AE1/AE3. Micrometastases were defined as tumor deposits >0.2 mm but <2 mm. Isolated tumor cells were defined as ≤0.2 mm. Medical records and survival data were reviewed. We identified 21 cases, consisting of 370 lymph nodes. Six of 21 patients (29%) had occult metastases, including 5 occult metastatic UC and 1 occult metastatic prostate adenocarcinoma. There were 10 positive LNs; 2 macrometastases, 2 micrometastases, and 6 with ITCs. Two of 6 patients (33%) had lymphovascular invasion identified in the primary tumor. Kaplan-Meier analysis showed no significant difference in overall survival between the group of patients who remained N0 versus those upstaged due to discovery of occult metastases (P-value = .42). In patients with pT3 UC undergoing cystectomy, we demonstrated the presence of occult metastases in 29% of patients. The high percentage of occult metastases present in these cases possibly explains the proven survival advantage of removing "negative" LNs. This finding might also have implications in the histologic evaluation of LNs. Copyright © 2016 Elsevier Inc. All rights reserved.

Purpose: To report long-term results of a bladder preservation strategy for muscle-invasive bladder cancer (MIBC) using external beam radiation therapy and brachytherapy/interstitial radiation therapy (IRT). Methods and Materials: Between May 1989 and October 2011, 192 selected patients with MIBC were treated with a combined regimen of preoperative external beam radiation therapy and subsequent surgical exploration with or without partial cystectomy and insertion of source carrier tubes for afterloading IRT using low dose rate and pulsed dose rate. Data for oncologic and functional outcomes were prospectively collected. The primary endpoints were local recurrence-free survival (LRFS), bladder function preservation survival, and salvage cystectomy-freemore » survival. The endpoints were constructed according to the Kaplan-Meier method. Results: The mean follow-up period was 105.5 months. The LRFS rate was 80% and 73% at 5 and 10 years, respectively. Salvage cystectomy-free survival at 5 and 10 years was 93% and 85%. The 5- and 10-year overall survival rates were 65% and 46%, whereas cancer-specific survival at 5 and 10 years was 75% and 67%. The distant metastases-free survival rate was 76% and 69% at 5 and 10 years. Multivariate analysis revealed no independent predictors of LRFS. Radiation Therapy Oncology Group grade ≥3 late bladder and rectum toxicity were recorded in 11 patients (5.7%) and 2 patients (1%), respectively. Conclusions: A multimodality bladder-sparing regimen using IRT offers excellent long-term oncologic outcome in selected patients with MIBC. The late toxicity rate is low, and the majority of patients preserve their functional bladder.« less

Summarizing the evidence on the effects of pre- and postoperative exercise and psychosocial rehabilitation interventions on patient-reported outcomes (PROs) and physical fitness in bladder cancer patients undergoing radical cystectomy. The Cochrane Central Register of Controlled Trials, MEDLINE, Embase, Web of Science and the Physiotherapy Evidence Database were searched independently by two authors from inception until 10 November 2017. Cited references of the studies and citing references retrieved via Web of Science were also checked. Randomized controlled trials (RCTs) and non-randomized studies assessing effects of exercise and psychosocial interventions in bladder cancer patients undergoing radical cystectomy were eligible. Primary outcome measures were PROs and physical fitness. Risk of bias was assessed using the Cochrane Collaboration tool and the Newcastle-Ottawa Scale. Five RCTs (three exercise and two psychosocial studies) and one non-randomized psychosocial study comprising 317 bladder cancer patients were included. Timing of the intervention was preoperative ( n = 2), postoperative ( n = 2) or both pre- and postoperative ( n = 2). Positive effects of exercise were found for physical fitness ( n = 3), some health-related quality-of-life (HRQoL) domains ( n = 2), personal activities in daily living ( n = 1) and muscle strength ( n = 1). Psychosocial interventions showed positive effects on anxiety ( n = 1), fatigue ( n = 1), depression ( n = 1), HRQoL ( n = 1) and posttraumatic growth ( n = 1). Quality assessment showed most shortcomings with sample sizes and strong heterogeneity was observed between studies. The evidence relating to the effects of exercise in bladder cancer is very limited and is even less for psychosocial interventions.

The treatment results for invasive transitional cell carcinoma (TCC) of the bladder were assessed in a series of 390 patients referred to the Department of Radiation Oncology at the Prince of Wales Hospital, Sydney, Australia, during the period 1977 to 1988. These patients were managed by one of two strategies: cystectomy (87 patients) and radiation therapy (303 patients). Actuarial survival rates (death from any cause) were determined and comparisons were made using log-rank tests and Cox regression analyses. The mean follow-up time was 7.6 years. Independent prognostic factors for shorter survival were: the presence of a ureteric obstruction (P less than 0.001), increasing clinical stage (P less than 0.001), increasing patient age (P = 0.003), and earlier year of presentation (P = 0.008). Comparison of the two strategies indicated no significant difference in overall survival after adjusting for imbalances in prognostic factors (P = 0.007 unadjusted; P = 0.29 adjusted). The slightly longer survival of 46 patients from 1983 onward who received primary systemic chemotherapy (compared with 149 patients not given chemotherapy) was not statistically significant (P = 0.12 unadjusted; P = 0.56 adjusted for prognostic factors). The 5-year actuarial rates of severe complications were 8.0% after cystectomy and 5.3% after radiation therapy. In 303 patients treated by definitive radiation therapy, the 5-year actuarial rate of freedom from bladder failure for all clinical tumor stages was 44% (Tx, 67%; T1, 45%; T2, 56%; T3, 39%; and T4, 39%). These results suggest that definitive radiation therapy is a viable alternative to radical cystectomy for patients with invasive TCC of the bladder.

Veno-occlusive dysfunction (formerly called "venous leakage") is a clinical-radiographic manifestation of a multi-aetiology syndrome, the pathogenesis of which is to be sought in intrinsic damage to the erectile tissue. It has been attributed to psycho-neurogenic, neurovascular and local--physical factors. The unsatisfactory results of the various surgical techniques proposed (venous ligatures, crural plication, corporopexy) can be explained by the formation of vicarious venous circles, a phenomenon which occurs regardless of the type of procedure adopted and which is the direct consequence of the alteration of the occlusive mechanisms intrinsic to the erectile tissue. At the Urological Institute of the University of Milan, a study has been carried out with the aim of experimentally assessing these aetiopathogenetic hypotheses. 48 sexually potent patients were selected from those scheduled for extensive surgical procedures on account of malignant pathologies of the pelvic cavity (urethro-prostato-cystectomy, radical prostatectomy). The protocol included a series of examinations before and after the operation (at three months): computerised recording of nocturnal erections (NPT test, three consecutive nights), dynamic penile Doppler velocimetry, dynamic cavernosometry/graphy, examination of bulbocavernosus reflex. The goal of the study was to evaluate the haemodynamic consequences of the massive venous ligatures effected during these operations (periprostatic plexus, deep dorsal vein, spongio-cavernous connections). There were 28 cases of radical prostatectomy and 20 cases of radical urethro-prostato-cystectomy. Among the cases of radical prostatectomy, the extrafascial retropubic technique was used for 14 patients, the monolateral nerve-sparing procedure was applied for 10 patients (stage B1) and the transperineal approach was used for 4 patients (the most recent).(ABSTRACT TRUNCATED AT 250 WORDS)

We aimed to evaluate the impact of topical hemostatic sealants and bipolar coagulation during laparoscopic ovarian endometriotic cyst resection on ovarian reserve by comparing the rates of decrease in anti-Müllerian hormone (AMH). A randomized prospective data collection was made on women aged 19-45 years who planned to have laparoscopic ovarian cystectomy at one of two institutions (n = 80), Kangbuk Samsung Hospital, Seoul, Korea or National Health Insurance Service Ilsan Hospital, Goyang, Korea, from January 2014 to April 2016. Patients were randomly divided into two groups treated with either a topical hemostatic sealant or bipolar coagulation for hemostasis. The hemostatic group was randomized to the FloSeal or TachoSil subgroups. Preoperative and 3-month postoperative AMH levels were checked and the rates of decrease of AMH were compared. All patients enrolled were treated with dienogest (Visanne) for 6-12 months. None were lost to follow-up at postoperative 3 months, but about one-third of the patients had been lost to follow-up by 6-12 months. AMH was significantly decreased in both groups 3 months postoperatively; however, the rate of decrease in the bipolar coagulation group was greater than that in the hemostatic sealant group, 41.9% (interquartile range [IQR], 22.29-65.24) versus 18.1% (IQR, 10.94-29.90), P = 0.007. Between the two hemostatic subgroups, there was no significant difference in AMH decrease rate, 14.95% (IQR, 11.34-21.21) versus 18.1% (IQR 9.76-40.70), P = 0.204. Hemostatic sealants may be an alternative to bipolar coagulation for preservation of ovarian reserve after laparoscopic ovarian cystectomy for endometriosis. © 2017 Japan Society of Obstetrics and Gynecology.

This study examined the effects of previous ovarian surgery on the clinical response to ovulation induction with clomiphene citrate-human menopausal gonadotropin in an in vitro fertilization program. Patients were divided into five clinical groups: group A (n = 63), no previous ovarian surgery; B (n = 9), unilateral cystectomy; C (n = 6), unilateral oophorectomy with no contralateral ovarian surgery; D (n = 7), bilateral ovarian surgery with both ovaries present; and E (n = 4), unilateral oophorectomy and contralateral cystectomy. Patients in group E demonstrated significantly lower serum estradiol on cycle days 9-11 (P less than or equal to .05) and fewer follicles on cycle days 11-12 (P less than or equal to .05) than did patients in groups A-D. The percentage of cancelled cycles increased with increasing amounts of ovarian surgery (P less than or equal to .03). The study suggests that one cause of a poor response to ovulation induction for in vitro fertilization may be prior extensive ovarian surgery.

Odontogenic cysts are defined as those cysts that arise from odontogenic epithelium and occur in the tooth-bearing regions of the jaws. Cystectomy, marsupialization or decompression of odontogenic cyst are treatment approach to this pathology. The aim of this study was to evaluate the effectiveness of the decompression as the primary treatment of the cystic lesions of the jaws and them reduction rates involving different factors. 23 patients with odontogenic cysts of the jaws, previously diagnosed by anatomical histopathology (follicular cysts (7) and radicular cysts (16)) underwent decompression as an initial treatment. Clinical examination and pre and post panoramic radiograph were measured and analyzed. In addition, data as gender, age, time reduction and location of the lesion were collected. Significant results were obtained in relation to the location of lesions and the reduction rate (p<0.01). In a higher initial lesion, a greater reduction rate was observed (p<0.05). Decompression as an initial treatment of cystic lesions of the jaws was effective; it reduces the size of the lesions avoiding a possible damage to adjacent structures. Cystic lesions in the mandible, regardless of the area where they occur will have a higher reduction rate if it is compared with the maxilla. Similar behavior was identified in large lesions compared to smaller.

To evaluate direct puncture embolization of the internal iliac artery with hemostatic gelatin sponge particles to treat pernicious placenta previa coexisting with placenta accreta during cesarean delivery. A retrospective study was conducted of data from women with pernicious placenta previa and placenta accreta who underwent direct puncture embolization of the internal iliac artery during cesarean delivery at a center in China between September 1, 2013, and February 28, 2015. Information regarding surgical procedures, operative data, and outcomes during hospitalization were obtained from medical records. The procedure was successful in all 16 cases included. Mean operative time was 78 minutes (range 65-90) and mean estimated blood loss was 1550 mL (range 1000-2500). Complications such as fever, buttock pain, or acute limb ischemia were not observed. The procedure was performed after partial cystectomy for two patients with bladder invasion. Postoperative Doppler imaging indicated uterine recovery and normalized uterine blood flow in all patients. Direct puncture embolization of the internal iliac artery during cesarean delivery was a safe, effective, simple, and rapid method to control hemorrhage among women with pernicious placenta previa and placenta accreta.

We compared the prognostic value of the American Joint Committee on Cancer (AJCC) TNM nodal staging system with that of lymph node (LN) density in patients with LN-positive bladder cancer who received extended or super-extended pelvic lymphadenectomy. Of the 1,018 patients, who underwent radical cystectomy and pelvic lymphadenectomy between February 2005 and August 2014, 110 patients with LN metastases with extended (n = 68) or super-extended (n = 42) pelvic lymphadenectomy were included. All patients were staged using the 2002 (sixth edition) and 2010 (seventh edition) AJCC TNM staging systems. The association of several variables with recurrence-free survival (RFS) and overall survival (OS) was evaluated. The median number of total LNs removed was 29 (6-118) and the median LN density was 12.5% (1.6%-100%). RFS and OS were not significantly different between the 2002 (pN1-pM1) and 2010 (pN1-N3) AJCC TNM nodal staging systems (sixth edition: P = 0.512 and P = 0.519; seventh edition: P = 0.676 and P = 0.671, respectively). The 2-year RFS and OS rates according to the LN density quartiles were 58.5% and 76.9% in Q1, 39.1% and 70.8% in Q2, 28.8% and 50.1% in Q3, and 12.7% and 20.8% in Q4 (P = 0.001 and P = 0.001, respectively). Multivariate analysis adjusted for the 2010 AJCC TNM staging system showed that LN density was associated with a decreased OS (HR = 1.024; 95% CI: 1.010-1.039; P = 0.001). The nodal staging system (2002 or 2010) was not associated with the RFS and OS. LN density shows a better prognostic value than the AJCC TNM nodal staging system in patients with LN-positive bladder cancer receiving extended or super-extended pelvic lymphadenectomy.

The inhibitory effects of different potassium channel openers (PCOs) on electrically generated and carbachol-induced contractions of porcine and human detrusor muscle were examined. PCOs could be an interesting substance class for treatment of detrusor overactivity. Experiments were performed on muscle strips suspended in a tissue bath. Human tissue originated from patients who underwent total cystectomy. The concentration-relaxation curves of the first-generation PCOs cromakalim and pinacidil and the untypical PCO minoxidil were performed using carbachol-precontracted detrusor muscle strips of pigs and humans. Additionally, the inhibitory effects of cromakalim, pinacidil and minoxidil on electrically generated contractions of porcine detrusor muscle were examined. Furthermore, the inhibitory effect of the second-generation, bladder-selective PCO ZM 226600 on electrically generated contractions of the human detrusor muscle was determined. Frequency-response curves were performed before and after incubation with one PCO used in two different concentrations. In humans, cromakalim and pinacidil led to a maximum decrease of 73.5 and 68.4% and showed mean pD2 values of 6.65 and 5.5, respectively. In pigs, cromakalim and pinacidil led to a maximum decrease of 90.6 and 93.6% and showed mean pD2 values of 6.39 and 5.01, respectively. Minoxidil did not significantly decrease the precontraction at the highest used concentration in both species. Cromakalim exhibited the biggest inhibitory effect being significant at 10(-5) and 10(-6) M. Pinacidil showed only a significant inhibitory effect at 10(-5) M which was smaller than that of cromakalim. At 3 x 10(-6) M only a very small effect occurred at 1 Hz. Minoxidil did not inhibit the contractions at both examined concentrations except for a very small effect at 1 Hz. In humans, ZM 226600 exhibited at 10(-6) and 10(-5) M a significant inhibitory effect. At 10(-7) M it was only significant at one frequency.

To update long-term results with selective organ preservation in invasive bladder cancer using aggressive transurethral resection of bladder tumor (TURBT) and radiochemotherapy (RCT) and to identify treatment factors that may predict overall survival (OS). Between 1990 and 2007, a total of 74 patients with T2-T4 bladder cancer were enrolled in 2 sequential bladder-sparing protocols including aggressive TURB and RCT. From 1990 to 1999, 41 patients were included in protocol no. 1 (P1) that consisted of three cycles of neoadjuvant methotrexate, cisplatin, and vinblastine (MCV) chemotherapy prior to re-evaluation and followed by radiotherapy (RT) 60 Gy in complete responders. Between 2000 and 2007, 33 patients were entered in protocol no. 2 (P2) that consisted of concurrent RCT 64, 8 Gy with weekly cisplatin. In case of invasive residual tumor or recurrence, salvage cystectomy was recommended. Primary endpoints were OS, overall survival with bladder preservation (OSB), and late toxicity. The mean follow-up for the whole series was 54 months (range 9-156), 69 months for patients in P1 and 36 months for patients in P2. The actuarial 5-year OS and OSB for all series were 72% and 60%, respectively. Distant metastases were diagnosed in 11 (15%) patients. Grade 3 late genitourinary (GU) and intestinal (GI) complications were 5% and 1.3%, respectively. There were no significant differences in the incidence of superficial recurrences (P = 0.080), muscle-invasive relapses (P = 0.722), distant metastasis (P = 0.744), grade >/=2 late complications (P = 0.217 for GU and P = 0.400 for GI), and death among the 2 protocols (P value for OS = 0.643; P value for OSB = 0.532). These data confirm that trimodality therapy with bladder preservation represents a real alternative to radical cystectomy in selected patients, resulting in an acceptable rate of the long-term survivors retaining functional bladders.

To evaluate the prognostic relevance of different prostatic invasion patterns in pT4a urothelial carcinoma of the bladder (UCB) after radical cystectomy. Our study comprised a total of 358 men with pT4a UCB. Patients were divided in 2 groups-group A with stromal infiltration of the prostate via the prostatic urethra with additional muscle-invasive UCB (n = 121, 33.8%) and group B with continuous infiltration of the prostate through the entire bladder wall (n = 237, 66.2%). The effect of age, tumor grade, carcinoma in situ, lymphovascular invasion, soft tissue surgical margin, lymph node metastases, administration of adjuvant chemotherapy, and prostatic invasion patterns on cancer-specific mortality (CSM) was evaluated using competing-risk regression analysis. Decision curve analysis was used to evaluate the net benefit of including the variable invasion pattern within our model. The estimated 5-year CSM-rates for group A and B were 50.1% and 66.0%, respectively. In multivariable competing-risk analysis, lymph node metastases (hazard ratio [HR] = 1.73, P<0.001), lymphovascular invasion (HR = 1.62, P = 0.0023), soft tissue surgical margin (HR = 1.49, P = 0.026), absence of adjuvant chemotherapy (HR = 2.11, P<0.001), and tumor infiltration of the prostate by continuous infiltration of the entire bladder wall (HR = 1.37, P = 0.044) were significantly associated with a higher risk for CSM. Decision curve analysis showed a net benefit of our model including the variable invasion pattern. Continuous infiltration of the prostate through the entire bladder wall showed an adverse effect on CSM. Besides including these patients into clinical trials for an adjuvant therapy, we recommend including prostatic invasion patterns in predictive models in pT4a UCB in men.

2017-08-01

Background Adjuvant Bacillus Calmette-Guérin (BCG) intravesical instillation is the recommended standard treatment in patients with high-risk non-muscle-invasive bladder cancer (NMIBC). However, a significant proportion of patients fail treatment, and radical cystectomy (RC) is the subsequent gold standard. On the other hand, there is an unmet need for conservative alternatives for patients who are unfit or unwilling to undergo surgery. This study aimed to identify conservative treatment options in NMIBC patients after BCG failure. Material and Methods We performed a systematic search in the databases Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE, including all randomised controlled trials (RCTs), quasi-RCTs and single-arm studies, in which patients with NMIBC were treated with second-line intravesical or systemic therapy after BCG failure. A minimum of eight patients were included in each treatment arm. Full papers were restricted to English language. Literature research and data analysis were assessed independently by two reviewers. Data on treatment response, recurrence, time to recurrence, progression and rate of cystectomy were collected and analysed. Results  This systematic review included 42 publications with a total of 3521 patients (2371 BCG failures). Valrubicin, taxanes, gemcitabine, combination chemotherapy, thermochemotherapy, photodynamic therapy, combination of BCG and interferon and immunotherapies or targeted therapies were identified as conservative treatment options. For taxanes, gemcitabine and thermochemotherapy there is the highest evidence for a clinical meaningful response with minor toxicities. Conclusions Despite some promising response rates for taxanes, gemcitabine or thermochemotherapy, an evidence-based recommendation for treatment options superior to RC in patients failing BCG therapy cannot be made. The definition of BCG failure is still inconsistent and heterogeneous outcomes in patients with BCG failure have been reported. In order to identify effective conservative therapy options in patients failing BCG therapy, prospective trials with a standardised trial design are needed. © Georg Thieme Verlag KG Stuttgart · New York.

To evaluate the incidence, risk factors, and timing of infections following radical cystectomy (RC). The American College of Surgeons National Surgical Quality Improvement Project database was queried to identify patients undergoing RC for bladder cancer from 2006 to 2013. Characteristics including year of surgery, age, sex body mass index, diabetes, smoking, renal function, steroid usage, preoperative albumin, preoperative hematocrit, perioperative blood transfusion (PBT), and operative time were assessed for association with the risk of infection within 30 days of RC using multivariable logistic regression. A total of 3,187 patients who had undergone RC were identified, of whom 766 (24.0%) were diagnosed with a postoperative infection, at a median of 13 days (interquartile ranges 8-19) after RC. Infections included surgical site infection (SSI) (404; 12.7%), sepsis/septic shock (405; 12.7%), and urinary tract infection (UTI) (309; 9.7%). On multivariable analysis, body mass index≥30kg/m 2 (odds ratios [OR] = 1.52; P<0.01), receipt of a PBT (OR = 1.27; P<0.01), and operative time≥480 minutes (OR = 1.72; P<0.01) were significantly associated with the risk of infection. When the outcomes of UTI, SSI, and sepsis were analyzed separately, operative time≥480 minutes remained independently associated with increased infection risk in each model (OR = 2.11 for UTI, OR = 1.63 for SSI, and OR = 1.80 for sepsis/septic shock; all P<0.05), whereas PBT was associated with SSI and sepsis/septic shock (OR = 1.33 and OR = 1.29, respectively; both P< 0.05). Approximately 25% of patients undergoing RC experience an infection within 30 days of surgery. Several potentially modifiable risk factors for infection were identified, specifically PBT and prolonged operative time, which may represent opportunities for future care improvement.

2017-01-01

Most cases with advanced-stage epithelial ovarian malignancies will experience recurrent disease at a certain moment of their evolution, even if maximal cytoreductive surgery has been performed at the moment of initial diagnosis. However, it seems that the best therapeutic strategy, in case of relapse, remains aggressive re-resection, with complete cytoreduction being the most efficient way to improve survival. We present the case of a 55-year-old patient diagnosed with an isolated pelvic recurrence after stage IIIC surgically-treated ovarian cancer three years after primary cytoreduction. Intraoperatively, the diagnosis of an isolated pelvic recurrence invading the urinary bladder was confirmed. The recurrent tumor was resected en bloc with partial cystectomy. The postoperative course was uneventful, while histopathological studies confirmed the presence of a poorly differentiated epithelial ovarian recurrent adenocarcinoma. At two year follow-up, the patient is free of any recurrent disease. Isolated pelvic recurrences after surgically-treated ovarian adenocarcinomas can be safely removed and might improve survival.

To reduce short-term complications of radical cystectomy (RC) and intestinal urinary diversion with vescica ileale Padovana (VIP) neobladder, we described and assessed an enhanced recovery protocol (ERP) in a series of consecutive patients. An ERP was introduced focusing on reduced bowel preparation, standardized feeding and analgesic regimens. We analyzed the outcomes with all patients consecutively undergoing RC and VIP neobladder who met the following inclusion criteria: American Society of Anesthesiologists score <3; absence of malnutrition according to the Mini Nutritional Assessment-Short Form criteria; absence of inflammatory bowel diseases. Thirty-one consecutive patients were recruited to undergo our ERP. Mean age of patients was 62.16 years. No patients died due to surgical complications. Nine of 31 patients experienced complications (29.03%), none requiring surgical intervention. According to Clavien grading, all complications were grade <2. The application of our ERP to our patients undergoing RC and VIP neobladder contributed to reduce postoperative morbidity. Copyright © 2013 S. Karger AG, Basel.

It aims at investigating the expression and distribution of the Osteopontin (OPN) in the pericyst of human hepatic Echinococcus granulosus and their related significances. Sixty pericysts excised by "sub-adventitial cystectomy" were studied. OPN was detected in 80% (48/60) of cysts by Western blotting and distributed in the side of "exocyst" layer directing to the parasite, also macrophages were identified in the vicinity of OPN by immunohistochemistry staining. The coexpression of OPN and CD68 was observed by immunofluorescence double labeling and analyzed by Image-Pro Plus 5.1; with special stain techniques, variable degrees of calcium deposits were observed in 80% (48/60) cysts, and the calcium deposits concurrencely found with the OPN expression. The selective distribution of OPN, calcium in the "exocyst" provides a new pathological evidence for the "sub-adventitial cystectomy" we developed. The pericyst of hepatic E. granulosus consists of two detachable layers with different formative mechanisms: the "exocyst" layer directing towards the cyst of parasite was the result of granulomatous reaction; also the results suggest OPN is one regulator in the granulomatous reaction and calcification of "exocyst".

Current trends in the management of bladder cancer.

This article provides a review of bladder cancer etiology, diagnosis, and management for WOC nurses. Bladder cancer incidence continues to rise yearly in the United States, and patients with bladder cancer comprise some of the most challenging cases in urologic oncology. Nurses are involved with all aspects of the processes of care for the patient with bladder cancer, from initial diagnosis and treatment to postsurgical care and follow-up. For nonmuscle invasive bladder cancer, treatment includes transurethral resection followed by intravesical chemotherapy or immunotherapy to prevent recurrence or progression. Radical cystectomy along with chemotherapy protocols provides a survival advantage for muscle invasive bladder cancer, although the timing of chemotherapy remains controversial. Numerous factors are considered when determining the type of urinary diversion used at the time of radical cystectomy, but patient, family, surgeon, and nursing input are essential for preserving an optimal health-related quality of life and reducing morbidity. Patients with metastatic bladder cancer are generally treated with a cisplatin-based chemotherapy but continue to have a poor prognosis. Newer therapies involving novel molecular-targeted agents provide hope for the future for patients with metastatic disease.

Postcystectomy bladder cancer (BCa) patients are at high risk for developing venous thromboembolism (VTE). The literature varies widely in the reporting of VTE in this population. To determine the VTE rate in subjects undergoing radical cystectomy (RC) and highlight specific factors affecting this rate. This meta-analysis was registered with the International Prospective Register of Systematic Reviews (PROSPERO) database, registration number: CRD42015016776. We queried MEDLINE, the Cochrane Library, Embase, Scopus, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Web of Science. Search terms captured BCa, RC, and VTE. Per the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines, abstracts were reviewed for inclusion/exclusion criteria by two reviewers, and disagreements were resolved by a third reviewer. A search of the gray literature and references of pertinent articles was also performed. The date of our last search was December 15, 2014. For unreported data, authors were contacted. Data were abstracted in duplicate and pooled using a random effects (RE) model. Subgroup analyses and meta-regression were performed to determine risk factors for VTE. We identified 2927 publications, of which 223 met inclusion criteria for this review. A total of 1 115 634 surgeries were performed on patient population (80% men) with a total of 51 908 VTEs. The VTE rate estimated by the RE model was 3.7%. Due to significant heterogeneity, subgroup and meta-regression analyses were undertaken. These revealed a higher rate of VTE in US studies at 4.49% compared with "westernized" non-US studies at 3.43% and "nonwesternized" non-US based studies at 2.50%. Other important modifiers included minimally invasive surgery at 5.54% versus open surgery at 3.55%, and age. The case-fatality rate of pulmonary emboli was 44%. VTE is common in patients undergoing RC. Reporting of VTE is heterogeneous and the rate varies according to study-level factors, including surgery type and country of origin. Limitations of this study include the preponderance of observational studies in the final analysis and lack of complete reporting of all variables of interest within each study. In this review, we determined the venous thromboembolism (VTE) rate in postsurgical bladder cancer patients. VTE events did vary significantly among certain subgroups.

STUDY QUESTION Is bilateral tubotubal anastomosis a successful treatment in an outpatient patient population? SUMMARY ANSWER For women wanting children after tubal sterilization, bilateral tubotubal anastomosis is an effective outpatient treatment. WHAT IS KNOWN ALREADY With the current emphasis in reproductive medicine on high technology procedures, the effectiveness of female surgical sterilization reversal is often overlooked. Previous clinical studies of tubal sterilization reversal have been mostly retrospective analyses of small patient populations. STUDY DESIGN, SIZE, DURATION A cohort of women who underwent outpatient bilateral tubotubal anastomosis from January 2000 to June 2013 was followed prospectively until December 2014 to determine the proportions of women undergoing the procedure who became pregnant and who had live births. Data were collected at the time of pregnancy. Differences in pregnancy rates and live birth rates associated with age, race and sterilization method were evaluated. PARTICIPANTS/MATERIALS, SETTING, METHODS A total of 6692 women, aged 20–51 years, underwent outpatient bilateral tubotubal anastomosis. MAIN RESULTS AND THE ROLE OF CHANCE The crude overall pregnancy rate was 69%. The crude overall birth rate was 35%. Results varied according to age at sterilization reversal and the method of sterilization. Women under 30 years of age at reversal of ring/clip sterilizations had an 88% pregnancy rate and 62% birth rate. Pregnancy and birth rates declined as age increased at sterilization reversal. Coagulation sterilization reversals resulted in the lowest rates of pregnancies and births. Ligation/resection reversals had intermediate success rates. LIMITATIONS, REASONS FOR CAUTION Limitations of our study include probable underreporting of pregnancies based on patient-initiated reports; possible errors in the reporting of pregnancies or early miscarriages that may have been based solely on home pregnancy tests; and probable over-reporting of the diagnosis of ectopic pregnancies. We identified age and sterilization method as being associated with subsequent pregnancy, however, in order to be considered predictive, the associations would need to be validated in an independent second prospectively studied group of representative patients. Finally, we also included patients in the study population who had additional surgical procedures performed at the time of tubotubal anastomosis (e.g. uterine myomectomy, fimbrioplasty, ovarian cystectomy and adhesiolysis), factors that could result in differences in pregnancy statistics in our study versus other patient populations. WIDER IMPLICATIONS OF THE FINDINGS The results of this study can help inform patients and clinicians about this low technology alternative to IVF. STUDY FUNDING/COMPETING INTEREST(S) None.

Purpose: There is strong interest in partial-bladder radiation whether as a boost or definitive therapy to limit long-term toxicity. It is unclear that a standard preoperative examination can accurately identify all sites of disease within the bladder. The purpose of this study was to determine the correlation between preoperative localization of bladder tumors with postoperative findings to facilitate partial-bladder radiation techniques when appropriate. Methods and Materials: We examined patients with clinically staged T1-T4 invasive transitional cell carcinoma (TCC) or TCC with variant histology with no history of radiation or partial cystectomy undergoing radical cystectomy. Patients were scored as “under-detected” ifmore » a bladder site was involved with invasive disease (≥T1) at the time of cystectomy, but not identified preoperatively. Patients were additionally scored as “widely under-detected” if they had postoperative lesions that were not identified preoperatively in a given site, nor in any adjacent site. Rates of under-detected and widely under-detected lesions, as well as univariate and multivariate association between clinical variables and under-detection, were evaluated using logistic regression. Results: Among 222 patients, 96% (213/222) had at least 1 area of discordance. Fifty-eight percent of patients were under-detected in at least 1 location, whereas 12% were widely under-detected. Among 24 patients with a single site of disease on preoperative evaluation, 21/24 (88%) had at least 1 under-detected lesion and 14/24 (58%) were widely under-detected. On multivariate analysis, only solitary site of preoperative disease was associated with increased levels of under-detection of invasive disease (OR = 4.161, 95% CI, 1.368-12.657). Conclusion: Our study shows a stark discordance between preoperative and postoperative localization of bladder tumors. From a clinical perspective, incomplete localization of all sites of disease within the bladder may lead to marginal misses when a partial-bladder technique is used.« less

The incidence of Urinary tract endometriosis (UTE) ranges from 1% to 3%; bladder is the most affected organ (85% of UTE), followed by ureter (12 - 14% of UTE), for which we distinguish an intrinsic very rare form and an extrinsic variety most frequently occurring in advanced pelvic endometriosis. From 1997 to 2010, 33 surgical procedures for urologic endometriosis were performed, involving the urinary tract, in 28 patients with mean age of 31 years (25-43). The localization of endometriosis were: 7 cases in the bladder, 2 cases in the vesicoureteral tract, and 19 cases of ureteral tract only. Of these, two cases were diagnosed with an intrinsic localization. Overall, we performed 3 TURB, 5 partial cystectomies (2 with open surgical approach and 3 by laparoscopy procedure), 12 laparoscopic ureterolysis and simultaneous protection of the upper urinary tract with stent, 9 cases of ureterocystoneostomy (UCNS) according to Lich-Gregoire procedure, and 3 according to Boari-Kuess procedure. Of the 12 patients who underwent ureterolysis with laparoscopic and stenting procedure, five cases required a UCNS according to Lich-Gregoire technique for persistent ureteral obstruction. The limits of endoscopic procedures in endometriosis of the urinary tract are correlated both to the degree of extension and the localization of the disease. It is mandatory to achieve an interdisciplinary consensus in order to ensure the disease removal and the simultaneous functional results of the upper urinary tract.

The aim of this study was to examine the efficacy of the antirefluxing, mucosal-flap valve (AMFV) for biliary drainage relative to technical feasibility, surgical complications, and incidence of ascending cholangitis (AC). Twenty-seven infants requiring biliary tract reconstruction underwent valve construction. Twenty biliary atresia (BA) patients received the Kasai procedure, and 7 choledochal cyst (CC) infants had cystectomy and hepatoenterostomy. A retrospective review of all patients was performed including radiographic evaluation of the current valve function in 10 patients. Construction was successful in all cases, and no morbidity was incurred by incorporation of the valve. Of 7 CC patients, there have been no known episodes of AC with mean follow-up of 4.4+/-4.2 years. Of 20 BA patients, there have been 5 deaths (25%), 7 liver transplants (35%), 2 (10%) lost to follow-up, and 6 (30%) survivors. Nine BA patients (45%) have had AC, with patients in all 4 outcome categories represented. Ten patients (5 CC and 5 BA) have been evaluated with barium small bowel radiographs, with no reflux to the liver hilum in all cases. The AMFV has caused no morbidity and continues to prevent reflux to the liver hilum. Despite functioning as designed, it does not appear to influence the occurrence of AC. Because CC patients had no AC, we feel that infection is related to the underlying atresia rather than to reflux.

Pheochromocytomas are catecholamine producing neuroendocrine tumours. Bladder involvement with pheochromocytoma is rare that usually presents with hypertension, hematuria and syncope often related to voiding. Clinical manifestation may be inconsistent and high index of suspicion is required for accurate diagnosis. We report a case, who presented with gross intermittent hematuria and mild elevation of pulserate and bloodpressure. Patient was adequately treated with partial cystectomy.

Advanced Surgery We have the expertise to do complex reconstructive procedures with robotic assistance. This results in: smaller incisions, less blood loss, and shorter stays in the hospital In the most challenging of cases of radical cystectomy, we remove the bladder and replace it with a bladder that we construct from bowel tissue. This is standard-of-care for advanced cases.

Xanthogranulomatous cystitis (XC) is a very rare chronic benign inflammatory disease of the bladder. It may cause local invasion although it is not a malign lesion and may occur together with malign lesions. It has a clinical importance as the distinction from malign lesions is difficult clinically and pathologically. Sharing a 37-year-old female case with giant XC imitating bladder tumor referring to the hospital with hematuria and stomach ache, together with current literature, we wanted to present that the disease can be treated with bladder-preserving approaches instead of radical approaches even though the mass is big in these cases. Application of basic excision and partial resection for small masses and radical cystectomy for large masses was reported in literature. We think that our case may provide a contribution to literature in treatment approach since we provided surgical cure with partial resection in a big mass with dimensions of 9 cm × 8 cm which is different from the present literature. Even though XC is a rare disease, it should be considered in prediagnosis for especially big dimensioned masses, and treatment should be planned according to the pathology result after together with cystoscopy in suitable patients.

2010-01-01

Patients being treated for bladder cancer share issues in common with other cancer patients, but also experience issues that are unique to their surgical treatment. This study used a descriptive qualitative approach to explore the experiences of patients who had undergone radical cystectomy for bladder cancer Twenty-two participants were interviewed in-depth on one occasion and were invited to attend a focus group session following the analysis of the interview transcripts. Participants described the shock of their diagnosis, their lack of information about bladder cancer, the importance of clear communication with care providers, and the types of adjustments they had to make following surgery. Specifically, changes in bodily function, body image, sexual relationships, and intimacy presented challenges for these participants. Although there was a sense of acceptance about the treatment-related events, there were still significant adjustments required by individuals following their surgery. Information, open communication, and support from family and friends were seen as important factors in helping patients adjust after surgery. Patients require clear, concise and consistent information about their cancer, treatment options, and course of care. Nurses caring for patients following surgery for bladder cancer need to understand the unique needs of these patients.

The Authors report their 7 year follow-up on the use of T.P.N. in 28 patients treated surgically for infiltrating cancer of the bladder. They consider the pathogenetic mechanisms that influence the organism's adaptation to surgical stress with particular reference to the multiple neuroendocrinal and biochemical interconnections. The procedures to define the nutritional/metabolic levels, of the patients undergoing operation are exposed. The T.P.N. is given according to the personal requirements of each patient and is a function of the "performance status", caloric need and to the presence of sepsis. Problems concerning the radical cistectomy such as: time of surgery, extention of exeresis, uroentheroanastomosis, metabolic variations, sepsis, etc., are evaluated. Considering the positive results obtained with this nutritional procedure, the Authors underline the importance of a systematic use of T.P.N. wich should be included, in their opinion, in a multidisciplinar treatment of advanced bladder neoplasms.

Predictors of the use of orthotopic bladder reconstruction after radical cystectomy for bladder cancer: data from a pilot study of 1756 cases 2004-2011.

WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: How often orthotopic reconstruction should be used after radical cystectomy is uncertain. Male sex, younger age, affluence, white ethnicity and treatment in specialist hospitals may be associated with more frequent use. More evidence about the level and likely variation in the use of orthotopic surgery is needed to establish whether there are inequalities and unmet need. In England during the study period orthotopic bladder reconstruction was likely to be used in about one in 15 patients treated by radical cystectomy. This is lower than previously reported in US series or European studies. Men and younger patients were more likely to be treated by orthotopic reconstruction, as were more affluent patients and those with less advanced disease. Whether clinical reasons or patient choice can explain some of this variation is unclear. There was no evidence for variation between different English cancer networks. A specific procedure code to allow routine analysis of population-based nationwide data would be invaluable for ongoing monitoring of potential inequalities and unmet need. To examine variation in the use of orthotopic bladder reconstruction. Variability in the use of orthotopic reconstruction may indicate potential for quality improvement. We analysed data from the British Association of Urological Surgeons Cancer Registry Complex Operations data set and Hospital Episode Statistics, covering the period 2004-2011. Three-level (patient, consultant and cancer network) mixed effect logistic regression models were used to examine sociodemographic and organizational variation in use of orthotopic reconstruction. The primary outcome was the odds ratio for use of orthotopic reconstruction for different patient groups. The final analysis sample included 1756 patients with bladder cancer who were treated by cystectomy by 121 consultants in 17 cancer networks. Of these, 120 (6.8%) were treated by orthotopic bladder reconstruction by 49 consultants in 14 cancer networks. In multivariable analysis, use of orthotopic surgery was higher in younger patients (odds ratio [OR] = 0.37 per increasing 10-year age group from 30-39 to ≥70, P ≤ 0.001) and men (OR = 2.31, P = 0.005). There was also some evidence of less frequent use among more deprived patients (OR per decreasing deprivation quintile 1.17, P = 0.037) and those with advanced disease (OR per increase in stage category 0.8, P = 0.037). After accounting for patient- and consultant-level variation, there was very limited variation in the use of orthotopic reconstruction between different cancer networks. Within the study context, use of orthotopic surgery was relatively rare and variable between patients with different characteristics but not between different cancer networks. The extent by which this variation reflects variation in quality of care or patient choice is uncertain. Examining the dissemination of orthotopic surgery use using nationwide data is advisable. © 2013 BJU International.

New clinical trial open for patients with muscle-invasive bladder cancer | Center for Cancer Research

Cancer.gov

Muscle-invasive bladder cancer is an aggressive form of bladder cancer in which the tumor invades deep into the musculature of the bladder wall, making it more likely to spread to other parts of the body. Standard treatment involves cisplatin-based chemotherapy followed by radical cystectomy, which is surgery to remove the bladder and nearby organs. However, many patients

The purpose of this study was to evaluate the surgical treatment results of urothelial carcinoma (UC) and pure squamous cell carcinoma of the bladder (SCC). The records of 460 patients who have undergone radical cystectomy in our department between the years 1991 and 2011 were analyzed retrospectively, and 364 patients with UC and 60 patients with pure SCC were evaluated. Average ages of the patients with UC and SCC were 61.12 ± 8.9 and 59.38 ± 8.6 years, respectively (p = 0.902). UC group had 29 female patients, whereas SCC group had 9 female patients (p = 0.077). The mean follow-up periods were 26.09 ± 24.75 months for UC group and 22.23 ± 31.01 months for SCC group (p = 0.805). The incidence of organ-confined, extravesical, lymph node-positive diseases in UC and SCC cases was 48.9 and 32.2, 29.3 and 32.2 %, 21.8 and 35.6 %, respectively (p = 0.028). Five-year disease-specific survival (DSS) rates were 57.5 % in UC and 39.1 % in SCC group (p = 0.011). Five-year DSS rates were 81.2 % in UC and 75.0 % in SCC group in organ-confined disease (p = 0.534) and 28.2 % in UC and 40.9 % in SCC group in extravesical disease (p = 0.845). In lymph node-positive patients, DSS time was 20.9 ± 2.85 months in UC and 12.8 ± 2.07 months in SCC patients (p = 0.182). In multivariate analysis, pT stage (HR: 2.221; 95 % CI: 1.695-2.911) and lymph node involvement (HR: 2.863; 95 % CI: 1.819-4.509) were independently associated with DSS (p < 0.001), but histological subtype (HR: 1.423; 95 % CI: 0.798-2.538) was not a statistically significant factor (p = 0.232). Although pure SCC cases are diagnosed at advanced stages of the disease, UC and pure SCC cases have similar prognosis by stages. Lymph node involvement and stages are the most important prognostic factors after radical cystectomy.

Pelvic lymph node dissection (PLND) has a diagnostic and therapeutic role during radical cystectomy in bladder cancer patients. However, at the time, no prospective data supports the value of extended PLND in improving survival expectances. We sought to describe incidence and location of node metastases in patients treated with extended and superextended PLND. We evaluated 653 contemporary patients with clinically nonmetastatic high risk nonmuscle invasive or muscle-invasive bladder cancer treated with radical cystectomy and extended or superextended PLND without neoadjuvant chemotherapy at a single tertiary referral center between 1990 and 2013. Limited PLND is defined as the removal of obturator and internal iliac nodes. Standard included also the external iliac nodes. Extended includes also common and presacral nodes. Finally, superextended PLND includes all the nodes removed along the inferior mesenteric artery. We evaluated incidence of pathologically node metastases. Logistic regression analyses evaluate preoperative and pathologic characteristics to the risk of harboring node metastases in the extended and superextended template. Overall, 191 (29.3%) patients were found with pathologically node confirmed metastases. Of these, 56 (29.3%) patients were found with a single node metastasis, while 135 (70.7%) had multiple node metastases. The vast majority of patients were found with node metastases standard template (n = 172, 26.3%), on the other hand 30 (4.6%) and 21 (3.2%) patients had node metastases in extended and superextended templates, respectively. However, of these only 2 patients were found without concomitant lymph node metastases in the limited or standard templates. On multivariable analyses, cN+ status (odds ratio = 4.40, P<0.001) and cT3-4 vs. cT1-2 (odds ratio = 2.25, P<0.001) were associated with an increased risk of harboring node metastases in the extended or superextended template. We found that the majority of patients harbored node disease in the limited or standard node dissection pattern. On the other hand, only a minority of patient were found with a disease in extended or superextended template without harboring a concomitant node disease in the limited pattern.

Urinary incontinence or the inability to void spontaneously after ileal orthotopic bladder substitution is a frequent finding in female patients. To evaluate how hysterectomy and nerve sparing affect functional outcomes and whether these relate to pre- and postoperative urethral pressure profile (UPP) results. Prospectively performed pre- and postoperative UPPs of 73 female patients who had undergone cystectomy and bladder substitution were correlated with postoperative voiding and continence status. Outcome analyses were performed with the Kruskal-Wallis test, Wilcoxon-Mann-Whitney, or two-group post hoc testing with the Bonferroni correction. Chi-square or Fisher exact tests were applied for the categorical data. Of postoperatively continent or hypercontinent patients, 22 of 43 (51.2%) had the uterus preserved; of incontinent patients, only 4 of 30 (13.3%, p<0.01) had the uterus preserved. Of postoperatively continent or hypercontinent patients, 27 of 43 patients (62.8%) had bilateral and 15 of 43 (34.9%) had unilateral attempted nerve sparing. In incontinent patients, 11 of 30 (36.7%) had bilateral and 16 of 30 (53.3%) had unilateral attempted nerve sparing (p=0.02). When compared with postoperatively incontinent patients, postoperatively continent patients had a longer functional urethral length (median: 32mm vs 24mm; p<0.001), a higher postoperative urethral closing pressure at rest (56cm H2O vs 35cm H2O; p<0.001) as well as a higher preoperative urethral closing pressure at rest (74cm H2O vs 47.5cm H2O; p=0.01). The main limitation was the limited number of patients. In female patients undergoing radical cystectomy and bladder substitution, preservation of the uterus and attempted nerve sparing results in better functional outcomes. The preoperative UPPs correlate with postoperative voiding and continence status and may predict which patients are at a higher risk of functional failure after bladder substitution. If preservation of the urethra's innervation is not possible during cystectomy, poor functional results with bladder substitutes are likely. Copyright © 2015 European Association of Urology.

To determine hospital resource utilization, associated costs and the risk of complications during hospitalization for four types of surgical resections and to estimate the incremental burden among patients with cancer compared to those without cancer. Patients (≥18 years old) were identified from the Premier Research Database of US hospitals if they had any of the following types of elective surgical resections between 1/2008 and 12/2014: lung lobectomy, lower anterior resection of the rectum (LAR), liver wedge resection, or total hysterectomy. Cancer status was determined based on ICD-9-CM diagnosis codes. Operating room time (ORT), length of stay (LOS), and total hospital costs, as well as frequency of bleeding and infections during hospitalization were evaluated. The impact of cancer status on outcomes (from a hospital perspective) was evaluated using multivariable generalized estimating equation models; analyses were conducted separately for each resection type. Among the identified patients who underwent surgical resection, 23 858 (87.9% with cancer) underwent lung lobectomy, 13 522 (63.8% with cancer) underwent LAR, 2916 (30.0% with cancer) underwent liver wedge resection and 225 075 (11.3% with cancer) underwent total hysterectomy. After adjusting for patient, procedural, and hospital characteristics, mean ORT, LOS, and hospital cost were statistically higher by 3.2%, 8.2%, and 9.2%, respectively for patients with cancer vs. no cancer who underwent lung lobectomy; statistically higher by 6.9%, 9.4%, and 9.6%, respectively for patients with cancer vs. no cancer who underwent LAR; statistically higher by 4.9%, 14.8%, and 15.7%, respectively for patients with cancer vs. no cancer who underwent liver wedge resection; and statistically higher by 16.0%, 27.4%, and 31.3%, respectively for patients with cancer vs. no cancer who underwent total hysterectomy. Among patients who underwent each type of resection, risks for bleeding and infection were generally higher among patients with cancer as compared to those without cancer. In this analysis, we found that patients who underwent lung lobectomy, lower anterior resection of the rectum (LAR), liver wedge resection or total hysterectomy for a cancer indication have significantly increased hospital resource utilization compared to these same surgeries for benign indications.

In the Materials and Methods section, the sentence that reads as "During the study period, our institution offered preoperative autologous blood donation to all patients who were scheduling for total joint arthroplasty with a hemoglobin level of no less than 11 mg/dL or a hematocrit level of at least 33%." in the print version now reads as "During the study period, our institution offered preoperative autologous blood donation to all patients who were scheduling for total joint arthroplasty with a hemoglobin level of no less than 11 g/dL or a hematocrit level of at least 33%." in the online version. In Table III, the footnote that reads as "The values are given as the estimate and the standard error in milligrams per deciliter." in the print version now reads as "The values are given as the estimate and the standard error in grams per deciliter." in the online version. Despite advances in surgical and anesthetic techniques, lower-extremity total joint arthroplasty is associated with considerable perioperative blood loss. As predictors of perioperative blood loss and allogenic blood transfusion have not yet been well defined, the purpose of this study was to identify clinical predictors for perioperative blood loss and allogenic blood transfusion in patients undergoing total joint arthroplasty. From 2000 to 2008, all patients undergoing unilateral primary total hip or knee arthroplasty who met the inclusion criteria were enrolled in the study. Perioperative blood loss was calculated with use of a previously validated formula. The predictors of perioperative blood loss and allogenic blood transfusion were identified in a multivariate analysis. Eleven thousand three hundred and seventy-three patients who underwent total joint arthroplasty, including 4769 patients who underwent total knee arthroplasty and 6604 patients who underwent total hip arthroplasty, were evaluated. Multivariate analysis indicated that an increase in blood loss was associated with being male (263.59 mL in male patients who had undergone total hip arthroplasty and 233.60 mL in male patients who had undergone total knee arthroplasty), a Charlson Comorbidity Index of >3 (293.99 mL in patients who had undergone total hip arthroplasty and 167.96 mL in patients who had undergone total knee arthroplasty), and preoperative autologous blood donation (593.51 mL in patients who had undergone total hip arthroplasty and 592.30 mL in patients who had undergone total knee arthroplasty). In patients who underwent total hip arthroplasty, regional anesthesia compared with general anesthesia reduced the amount of blood loss. The risk of allogenic blood transfusion increased with the amount of blood loss in the patients who underwent total hip arthroplasty (odds ratio, 1.43 [95% confidence interval, 1.40 to 1.46]) and the patients who underwent total knee arthroplasty (odds ratio, 1.47 [95% confidence interval, 1.42 to 1.51]), but the risk of blood transfusion increased with the Charlson Comorbidity Index only in patients who underwent total knee arthroplasty (odds ratio, 3.2 [95% confidence interval, 1.99 to 5.15]). The risk of allogenic blood transfusion decreased with preoperative autologous blood donation in patients who underwent total hip arthroplasty (odds ratio, 0.01 [95% confidence interval, 0.01 to 0.02]) and patients who underwent total knee arthroplasty (odds ratio, 0.02 [95% confidence interval, 0.01 to 0.03]).

Postcystectomy bladder cancer (BCa) patients are at high risk for developing venous thromboembolism (VTE). The literature varies widely in the reporting of VTE in this population. To determine the VTE rate in subjects undergoing radical cystectomy (RC) and highlight specific factors affecting this rate. This meta-analysis was registered with the International Prospective Register of Systematic Reviews (PROSPERO) database, registration number: CRD42015016776. We queried MEDLINE, the Cochrane Library, Embase, Scopus, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Web of Science. Search terms captured BCa, RC, and VTE. Per the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines, abstracts were reviewed for inclusion/exclusion criteria by two reviewers, and disagreements were resolved by a third reviewer. A search of the gray literature and references of pertinent articles was also performed. The date of our last search was December 15, 2014. For unreported data, authors were contacted. Data were abstracted in duplicate and pooled using a random effects (RE) model. Subgroup analyses and meta-regression were performed to determine risk factors for VTE. We identified 2927 publications, of which 223 met inclusion criteria for this review. A total of 1 115 634 surgeries were performed on patient population (80% men) with a total of 51 908 VTEs. The VTE rate estimated by the RE model was 3.7%. Due to significant heterogeneity, subgroup and meta-regression analyses were undertaken. These revealed a higher rate of VTE in US studies at 4.49% compared with "westernized" non-US studies at 3.43% and "nonwesternized" non-US based studies at 2.50%. Other important modifiers included minimally invasive surgery at 5.54% versus open surgery at 3.55%, and age. The case-fatality rate of pulmonary emboli was 44%. VTE is common in patients undergoing RC. Reporting of VTE is heterogeneous and the rate varies according to study-level factors, including surgery type and country of origin. Limitations of this study include the preponderance of observational studies in the final analysis and lack of complete reporting of all variables of interest within each study. In this review, we determined the venous thromboembolism (VTE) rate in postsurgical bladder cancer patients. VTE events did vary significantly among certain subgroups.

The current study was performed to examine temporal trends and compare overall survival (OS) in patients undergoing radical cystectomy (RC) or bladder-preservation therapy (BPT) for muscle-invasive urothelial carcinoma of the bladder. The authors reviewed the National Cancer Data Base to identify patients with AJCC stage II to III urothelial carcinoma of the bladder from 2004 through 2013. Patients receiving BPT were stratified as having received any external-beam radiotherapy (any XRT), definitive XRT (50-80 grays), and definitive XRT with chemotherapy (CRT). Treatment trends and OS outcomes for the BPT and RC cohorts were evaluated using Cochran-Armitage tests, unadjusted Kaplan-Meier curves, adjusted Cox multivariate regression, and propensity score matching, using increasingly stringent selection criteria. A total of 32,300 patients met the inclusion criteria and were treated with RC (22,680 patients) or BPT (9620 patients). Of the patients treated with BPT, 26.4% (2540 patients) and 15.5% (1489 patients), respectively, were treated with definitive XRT and CRT. Improved OS was observed for RC in all groups. After adjustments with more rigorous statistical models controlling for confounders and with more restrictive BPT cohorts, the magnitude of the OS benefit became attenuated on multivariate (any XRT: hazard ratio [HR], 2.115 [95% confidence interval [95% CI], 2.045-2.188]; definitive XRT: HR, 1.870 [95% CI, 1.773-1.972]; and CRT: HR, 1.578 [95% CI, 1.474-1.691]) and propensity score (any XRT: HR, 2.008 [95% CI, 1.871-2.154]; definitive XRT: HR, 1.606 [95% CI, 1.453-1.776]; and CRT: HR, 1.406 [95% CI, 1.235-1.601]) analyses. In the National Cancer Data Base, receipt of BPT was associated with decreased OS compared with RC in patients with stage II to III urothelial carcinoma. Increasingly stringent definitions of BPT and more rigorous statistical methods adjusting for selection biases attenuated observed survival differences.

What is the current management of women with ovarian endometriomas undergoing assisted reproductive treatment (ART) in the UK? It appears that the majority of gynaecologists in the UK offer surgery (mostly cystectomy) for endometriomas prior to ART, regardless of the presence of symptoms. The ideal management of endometriomas in women undergoing ART remains controversial and presents a dilemma to reproductive specialists. This was a national cross-sectional survey. A total of 388 gynaecologists completed the questionnaire. All clinicians fully registered with the Royal College of Obstetricians and Gynaecologists were contacted. An 11-item survey was administered electronically using Survey Monkey software. Quantitative data were analysed using descriptive and comparative statistics. The majority of responders were consultants (65%), 25% practiced ART and 65% performed laparoscopic surgery. Overall, 95% of responders would offer surgery for endometriomas in women undergoing ART, either on the basis of the size (>3-5 cm) of the endometrioma (52%), the presence of symptoms (16%), the presence of multiple/bilateral endometriomas (2%), regardless of the size and symptoms (19%) or only to women undergoing IVF (6%). The remaining 5% of responders would not offer surgery before ART. Excision was the most common surgical modality (68%), followed by ablation (25%). Laparoscopic surgeons were almost twice as likely to 'offer surgery to all patients with endometriomas prior to ART' compared with clinicians performing laparotomy (22 versus 12%, P < 0.001). Our overall response rate, with answers to the questionnaire, was low (15%). However, the response rate amongst reproductive specialists was estimated at 60%. It is possible that there might have been an element of bias towards over-representation of responders who are more concerned about 'normalization' of the pelvic anatomy. Furthermore, our survey relied on self-reporting of practice and it is possible that being presented with a list of 'ideal' options may have resulted in respondent bias. Despite the available evidence that surgery for endometriomas does not improve the outcome of ART and may damage ovarian reserve, it seems that the majority of gynaecologists in the UK offer ovarian cystectomy to their patients.

Epithelial borderline ovarian tumors (BOT) are distinctive from benign tumors and carcinoma. They occur in younger women more often than carcinoma, and there is some difficulty making correct diagnosis of BOT. Two subtypes of BOT, serous and mucinous borderline tumor have different characteristics and very different clinical behavior. Serous borderline tumor (SBT) with micropapillary pattern shows more incidence of extra ovarian disease and often coexists with invasive implant. SBT with micropapillary pattern in advanced stage has showed a worse prognosis than typical SBT. Huge mucinous borderline tumors have histologic heterogeneity, and the accuracy of frozen section diagnosis is relatively low. Extensive sampling is required to reach a correct pathological diagnosis. Mucinous adenoma (intestinal type) also runs the risk of recurrence after cystectomy, or intraoperative rupture of cyst. Laparoscopic procedure for BOT has not increased the risk of recurrence. Fertility preserving procedures are generally accepted, except in advanced stage SBT with invasive implants. Only cystectomy shows a significant risk of recurrence. Re-staging surgery and full staging surgery is not necessary for all BOT. We should not attempt to treat them uniformly, by the single diagnosis of "borderline tumor". It depends on histologic type. Close communication with the pathologist is necessary to gain more detail and ask more pathological samples in order to make the optimal treatment strategy for each individual patients.

The aim of our study was to evaluate the treatment outcomes of medical and surgical management of urinary tract endometriosis. Urinary tract endometriosis patients enrolled between Jan 2006 and May 2010 were retrospectively reviewed. Preoperative datas (mode of presentation, diagnosis, imaging), intraoperative findings (location and size of lesion), postoperative histopathology and follow-up were recorded and results were analyzed and the success rate of different modalities of treatment was calculated. In our study, of nineteen patients, nine had vesical involvement and ten had ureteric involvement. Among the vesical group, the success rate of transurethral resection followed by injection leuproide was 60% (3/5), while among the partial cystectomy group, the success rate was 100%. Among patients with ureteric involvement, success rate of distal ureterectomy and reimplantation was 100%, laparoscopic ureterolysis with Double J stenting followed by injection leuprolide was 75% while that of Gonadotropin- releasing hormone (GnRh) analogue alone was 67%. One should have a high index of suspicion with irritative voiding symptoms with or without hematuria, with negative urine culture, in all premenopausal women to diagnose urinary tract endometriosis. Partial cystectomy is a better alternative to transurethral resection followed by GnRh analogue in vesical endometriosis. Approach to the ureter must be individualised depending upon the severity of disease and dilatation of the upper tract to maximise the preservation of renal function.

To compare perioperative morbidity and oncological outcomes of robot-assisted laparoscopic radical cystectomy (RARC) to open RC (ORC) at a single institution. A retrospective analysis was performed on a consecutive series of patients undergoing RC (100 RARC and 100 ORC) at Wake Forest University with curative intent from 2006 until 2010. Complication data using the Clavien system were collected for 90 days postoperatively. Complications and other perioperative outcomes were compared between patient groups. Patients in both groups had comparable preoperative characteristics. The overall and major complication (Clavien ≥ 3) rates were lower for RARC patients at 35 vs 57% (P = 0.001) and 10 vs 22% (P = 0.019), respectively. There were no significant differences between groups for pathological outcomes, including stage, number of nodes harvested or positive margin rates. Our data suggest that patients undergoing RARC have perioperative oncological outcomes comparable with ORC, with fewer overall or major complications. Definitive claims about comparative outcomes with RARC require results from larger, randomised controlled trials. Copyright © 2014 Elsevier Inc. All rights reserved.

We report the case of Ms. A.A, a primiparous woman aged 21 years presenting (4 months after delivery) with an increase in left breast volume occurred 1 week after delivery associated with fever. The patient was put on amoxicillin, protected by suspending breast-feeding for several weeks without improvement. Clinical examination showed febrile patient with a temperature of 39°, an increase in left breast volume, inflammatory signs especially at the level of internal quadrants (A). Palpation showed a painful, hot collection adherent to the skin, measuring 16 cm, at the level of the internal quadrants, invading the external quadrants, without axillary adenopathies, suggesting breast abscess. Ultrasound (B) showed voluminous solidocystic predominantly liquid echogenic mass with thick walls and buds up to 46 mm, classified as ACR4. Puncture biopsy collected grayish green liquid, sent for bacteriological examination; antibiotic therapy with quinolones was started. Follow up of patient, after 3 days, showed reduction of the inflammatory signs and bacteriological examination of the liquid found no germ. After 15 days of antibiotic therapy, the inflammatory signs had disappeared and the volume of the mass had reduced enough, hence the indication for cystectomy. Cystectomy with simple enucleation was performed (C); surprisingly, the histological examination showed cystic fibroadenoma (D).

The aim of the present systematic review was to study the effect of bipolar electrocoagulation during ovarian cystectomy on ovarian reserve. We searched Medline (1966-2015), Scopus (2004-2015), ClinicalTrials.gov (2008-2015), and Cochrane Central Register (CENTRAL) databases along with reference lists of electronically retrieved studies. The levels of antimullerian hormone (AMH) and antral follicle count (AFC) at 1, 3, 6, and 12 months following the excision of the benign ovarian cyst were defined as primary outcomes. Eight studies were finally included in our systematic review, which recruited 545 women. A metaanalysis was precluded because of significant heterogeneity in the methodological characteristics of the included studies. Data from the included studies suggest that the use of bipolar coagulation compared with ovarian sutures seems to result in significantly lower AMH and AFC during the first 3 months following the excision of the ovarian cyst. Two studies reported that this effect seems to persist at 6 and 12 months postoperatively. Bipolar electrodiathermy seems to be accompanied by increased damage to ovarian reserve, which is indicated by the lower levels of AMH and AFC. However, definitive results are precluded because of the significant heterogeneity of included studies and the potential bias. Copyright © 2015 Elsevier Inc. All rights reserved.

To evaluate the incidence and the clinicopathological features of incidental prostate cancer detected in radical cystoprostatectomy (RCP) specimens in Chinese men and to estimate the oncological risk of prostate apex-sparing surgery for such patients. The clinical data and pathological feature of 504 patients who underwent RCP for bladder cancer from January 1999 to March 2013 were retrospectively reviewed. Whole mount serial section of the RCP specimens were cut transversely at 3-4 mm intervals and examined in same pathological institution. Thirty-four out of 504 patients (6.8%) had incidental prostate cancer with a mean age of 70.3 years. 12 cases (35.2%) were diagnosed as significant disease. 4 cases were found to have apex involvement of adenocarcinoma of the prostate while in 5 cases the prostate stroma invasion by urothelial carcinoma were identified (one involved prostate apex). The mean follow-up time was 46.4±33.8 months. Biochemical recurrence occurred in 3 patients but no prostate cancer-related death during the follow-up. There was no statistical significance in cancer specific survival between the clinically significant and insignificant cancer group. The prevalence of incidental prostate cancer in RCP specimens in Chinese patients was remarkably lower than in western people. Most of the incidental prostate cancer was clinically insignificant and patient's prognosis was mainly related to the bladder cancer. Sparing the prostate apex was potentially associated with a 1.0% risk of leaving significant cancer of the prostate or urothelial carcinoma.

We determined the long-term outcome in patients with superficial bladder cancer (Ta and T1) undergoing routine second transurethral bladder tumor resection (ReTURB) in regard to recurrence and progression. We performed an inception cohort study of 124 consecutive patients with superficial bladder cancer undergoing transurethral resection and routine ReTURB (83) between November 1993 and October 1995 at a German university hospital. Immediately after transurethral resection all lesions were documented on a designed bladder map. ReTURB of the scar from initial resection and other suspicious lesions was performed at a mean of 7 weeks. Patients were followed until recurrence or death, or a minimum of 5 years. Residual tumor was found in 33% of all ReTURB cases, including 27% of Ta and 53% of T1 disease, and in 81% at the initial resection site. Five of the 83 patients underwent radical cystectomy due to ReTURB findings. The estimated risk of recurrence after years 1 to 3 was 18%, 29% and 32%, respectively. After 5 years 63% of the patients undergoing ReTURB were still disease-free (mean recurrence-free survival 62 months, median 87). Progression to muscle invasive disease was observed in only 2 patients (3%) after a mean observation of 61 months. These data suggest a favorable outcome regarding recurrence and progression in patients with superficial bladder cancer who undergo ReTURB. ReTURB is suggested at least in those at high risk when bladder preservation is intended.

We report our initial experience regarding the feasibility, safety, benefits, and limitations of robot-assisted surgery in pediatric gynecological patients. Descriptive, retrospective report of experience with pediatric gynecological patients over a period of 12 months. Department of Pediatric Surgery, IRCCS Policlinico San Matteo Foundation. Children and adolescents, with a surgical diagnosis of ovarian and/or tubal lesions. Robot assembly time and operative time, days of hospitalization, time to cessation of pain medication, complication rate, conversion rate to laparoscopic procedure and trocar insertion strategy. Six children and adolescents (2.4-15 yrs), weighing 12-55 kg, underwent robotic assisted surgery for adnexal pathologies: 2 for ovarian cystectomy, 2 for oophorectomy, 1 for right oophorectomy and left salpingo-oophorectomy for gonadal disgenesis, 1 for exploration for suspected pelvic malformation. Mean operative time was 117.5 ± 34.9 minutes. Conversion to laparatomy was not necessary in any of the cases. No intra- or postoperative complications occurred. Initial results indicate that robotic assisted surgery is safely applicable in the pediatric gynecological population, although it is still premature to conclude that it provides better clinical outcomes than traditional laparoscopic surgery. Randomized, prospective, comparative studies will help characterize the advantages and disadvantages of this new technology in pediatric patients.

This study assessed the results of robotic thyroidectomy by fellowship-trained surgeons in their initial independent practice, and whether standard fellowship training for robotic surgery shortens the learning curve. This prospective cohort study evaluated outcomes in 125 patients who underwent robotic thyroidectomy using gasless transaxillary single-incision technique by 2 recently graduated fellowship-trained surgeons. Learning curves were analyzed by operation time, with proficiency defined as the point at which the slope of the time curve became less steep. Of the 125 patients, 113 underwent robotic less-than-total thyroidectomy, 9 underwent robotic total thyroidectomy and 3 underwent robotic total thyroidectomy with modified radical neck dissection. Mean total times for these 3 operations were 100.8 ± 20.6 minutes, 134.2 ± 38.7 minutes, and 284.7 ± 60.4 minutes, respectively. For both surgeons, the operation times gradually decreased, reaching a plateau after 20 robotic less-than-total thyroidectomies. The surgical learning curve for robotic thyroidectomy performed by recently graduated fellowship-trained surgeons with little or no experience in endoscopic surgery showed excellent results compared with those in a large series of more experienced surgeons. © 2014 Wiley Periodicals, Inc.

In this study, we aimed to evaluate the rarely reported long-term nutritional results of patients with gastric cancer after curative gastrectomy. We retrospectively reviewed the prospectively collected medical records of 658 patients who underwent radical gastrectomy with curative intent for gastric cancer from January 2008 to December 2009 and had no recurrences. All patients were followed for 5 years. Nutritional statuses were assessed using measurements of body weight, serum hemoglobin, total lymphocyte count (TLC), protein, albumin, cholesterol, and nutritional risk index (NRI). Patients who underwent total gastrectomy had lower body weights, hemoglobin, protein, albumin, and cholesterol levels. TLC and NRI valued after the first postoperative year (P<0.05), and lower hemoglobin and NRI valued during the fifth postoperative year than patients who underwent distal gastrectomy (P<0.05). Patients who received adjuvant chemotherapy after gastrectomy had lower hemoglobin, protein, albumin, and cholesterol levels. TLC and NRI valued during the first postoperative year, than those who underwent gastrectomy only (P<0.05). Regarding post-distal gastrectomy reconstruction, those who underwent Roux-en-Y had lower cholesterol levels than did those who underwent Billroth-I and Billroth-II reconstruction at the first and fifth years after gastrectomy, respectively (P<0.05). Patients undergoing total or distal gastrectomy with Roux-en-Y anastomosis or adjuvant chemotherapy after surgery should be monitored carefully for malnutrition during the first postoperative year, and patients undergoing total gastrectomy should be monitored for malnutrition and anemia for 5 years.

Sterilization via bilateral total salpingectomy is slowly replacing partial salpingectomy, as it is believed to decrease the incidence of ovarian cancer. Our objective was to compare short-term intra and post-operative complication rates of bilateral total salpingectomy versus partial salpingectomy performed during the course of a cesarean delivery. A large series of tubal sterilizations during cesarean sections were studied in a single tertiary medical center between 1/2014 and 8/2016 before and after a policy change was made, switching from partial salpingectomy to total salpingectomy. Patients who underwent bilateral partial salpingectomy using the modified Pomeroy technique were compared with those who underwent total salpingectomy. Operative length, estimated blood loss, postpartum fever, wound infection, need for re-laparotomy, hospitalization length, and blood transfusions were compared. During the study period, 149 women met inclusion criteria. Fifty parturients underwent bilateral total salpingectomy and 99 underwent partial salpingectomy in the course of the cesarean section. Demographic, obstetrical, and surgical characteristics were similar in both groups. Mean cesarean section duration was comparable for partial salpingectomy and total salpingectomy (a median of 35 min in both groups, P = 0.92). Complications were rare in both groups with no significant differences in rates of postpartum fever, wound infection, re-laparotomy, hospitalization length, estimated blood loss, transfusions, and readmissions within 1-month postpartum. Rates of short-term complications are similar in patients undergoing bilateral partial salpingectomy and total salpingectomy during cesarean deliveries, making the latter a feasible alternative to the former.

Here, we present a novel strategy for dissecting some of the steps involved in the squamous differentiation of the bladder urothelium leading to squamous cell carcinomas (SCCs). First, we used proteomic technologies and databases (http://biobase.dk/cgi-bin/celis) to reveal proteins that were expressed specifically by fresh normal urothelium and three SCCs showing no urothelial components. Thereafter, antibodies against some of the differentially expressed proteins as well as a few known keratinocyte markers were used to stain serial cryostat sections (immunowalking) of biopsies obtained from bladder cystectomies of two of the SCC-bearing patients (884-1 and 864-1). Because bladder cancer is a field disease, we surmised that the urothelium of these patients may exhibit a spectrum of abnormalities ranging from early metaplastic stages to invasive disease. Immunohistochemical analysis revealed three types of non-keratinizing metaplastic lesions (types 1-3) that did not express keratins 7, 8, 18, and 20 (expressed by normal urothelium) and could be distinguished based on their staining with keratin 19 antibodies. Type 1 lesions showed staining of all cell layers in the epithelium (with differences in the staining intensity of the basal compartment), whereas type 2 lesions exhibited mainly basal cell staining. Type 3 lesions did not stain with keratin 19 antibodies. In cystectomy 884-1, type 3 lesions exhibited the same immunophenotype as the SCC and may be regarded as precursors to the tumor. Basal cells in these lesions did not express keratin 13, suggesting that the tumor, which was also keratin 13 negative, may have arisen from the expansion of these cells. Similar results were observed with cystectomy 864-1, which showed carcinoma in situ of the SCC type. SCC 864-1 exhibited both keratin 19-negative and -positive cells, implying that the tumor arose from the expansion of the basal cell compartment of type 2 and 3 lesions. Besides providing with a novel strategy for revealing metaplastic lesions, our studies have shown that it is feasible to apply powerful proteomic technologies to the analysis of complex biological samples under conditions that are as close as possible to the in vivo situation.

Surgical trials have typically experienced recruitment difficulties when compared with other types of oncology trials. Qualitative studies have an important role to play in exploring reasons for low recruitment, although to date few such studies have been carried out that are embedded in surgical trials. The BOLERO trial (Bladder cancer: Open versus Lapararoscopic or RObotic cystectomy) is a study to determine the feasibility of randomisation to open versus laparoscopic access/robotic cystectomy in patients with bladder cancer. We describe the results of a qualitative study embedded within the clinical trial that explored why patients decline randomisation. Ten semi-structured interviews with patients who declined randomisation to the clinical trial, and two interviews with recruiting research nurses were conducted. Data were analysed for key themes. The majority of patients declined the trial because they had preferences for a particular treatment arm, and in usual practice could choose which surgical method they would be given. In most cases the robotic option was preferred. Patients described an intuitive 'sense' that favoured the new technology and had carried out their own inquiries, including Internet research and talking with previous patients and friends and family with medical backgrounds. Medical histories and lifestyle considerations also shaped these personalised choices. Of importance too, however, were the messages patients perceived from their clinical encounters. Whilst some patients felt their surgeon favoured the robotic option, others interpreted 'indirect' cues such as the 'established' reputation of the surgeon and surgical method and comments made during clinical assessments. Many patients expressed a wish for greater direction from their surgeon when making these decisions. For trials where the 'new technology' is available to patients, there will likely be difficulties with recruitment. Greater attention could be paid to how messages about treatment options and the trial are conveyed across the whole clinical setting. However, if it is too difficult to challenge such messages, then questions should be asked about whether genuine and convincing equipoise can be presented and perceived in such trials. This calls for consideration of whether alternative methods of generating evidence could be used when evaluating surgical techniques which are established and routinely available.

Bladder cancer (BC) is the ninth most common cancer worldwide. Radical cystectomy (RC) with neoadjuvant chemotherapy (NAC) is recommended for muscle-invasive BC. The challenge of the neoadjuvant approach relates to challenges in selection of patients to chemotherapy that are likely to respond to the treatment. To date, there are no validated molecular markers or baseline clinical characteristics to identify these patients. Different inflammatory markers, including tumor associated macrophages with their plastic pro-tumorigenic and anti-tumorigenic functions, have extensively been under interests as potential prognostic and predictive biomarkers in different cancer types. In this immunohistochemical study we evaluated the predictive roles of three immunological markers, CD68, MAC387, and CLEVER-1, in response to NAC and outcome of BC. 41% of the patients had a complete response (pT0N0) to NAC. Basic clinicopathological variables did not predict response to NAC. In contrast, MAC387 + cells and CLEVER-1 + macrophages associated with poor NAC response, while CLEVER-1 + vessels associated with more favourable response to NAC. Higher counts of CLEVER-1 + macrophages associated with poorer overall survival and CD68 + macrophages seem to have an independent prognostic value in BC patients treated with NAC. Our findings point out that CD68, MAC387, and CLEVER-1 may be useful prognostic and predictive markers in BC.

Aim: The aim of our study was to evaluate the treatment outcomes of medical and surgical management of urinary tract endometriosis. Materials and Methods: Urinary tract endometriosis patients enrolled between Jan 2006 and May 2010 were retrospectively reviewed. Preoperative datas (mode of presentation, diagnosis, imaging), intraoperative findings (location and size of lesion), postoperative histopathology and follow-up were recorded and results were analyzed and the success rate of different modalities of treatment was calculated. Results: In our study, of nineteen patients, nine had vesical involvement and ten had ureteric involvement. Among the vesical group, the success rate of transurethral resection followed by injection leuproide was 60% (3/5), while among the partial cystectomy group, the success rate was 100%. Among patients with ureteric involvement, success rate of distal ureterectomy and reimplantation was 100%, laparoscopic ureterolysis with Double J stenting followed by injection leuprolide was 75% while that of Gonadotropin- releasing hormone (GnRh) analogue alone was 67%. Conclusion: One should have a high index of suspicion with irritative voiding symptoms with or without hematuria, with negative urine culture, in all premenopausal women to diagnose urinary tract endometriosis. Partial cystectomy is a better alternative to transurethral resection followed by GnRh analogue in vesical endometriosis. Approach to the ureter must be individualised depending upon the severity of disease and dilatation of the upper tract to maximise the preservation of renal function. PMID:22346093

To present our technique of ureteroileal bypass to treat uretero-enteric strictures in urinary diversion. One hundred and forty-one medical records were reviewed from patients submitted to radical cystectomy to treat muscle-invasive bladder cancer between 2013 and 2015. Twelve (8.5%) patients developed uretero-enteric anastomotic stricture during follow-up. Five patients were treated with endoscopic dilatation and double J placement. Four were treated surgically with standard terminal-lateral implantation. Three patients with uretero-enteric anastomotic stricture were treated at our institution by "ureteroileal bypass", one of them was treated with robotic surgery. All patients had the diagnosis of uretero-enteric anastomotic stricture via computerized tomography and DTPA renal scan. Time between cystectomy and diagnosis of uretero-enteric anastomotic stricture varied from five months to three years. Mean operative time was 120±17.9 minutes (98 to 142 min) and hospital stay was 3.3±0.62 days (3 to 4 days). Mean follow-up was 24±39.5 months (6 to 72 months). During follow-up, all patients were asymptomatic and presented improvement in ureterohydronephrosis. Serum creatinine of all patients had been stable. Latero-lateral ureter re-implantation is feasible by open or even robotic surgery with positive results, reasonable operation time, and without complications.

Aim of the present study is to determine the effects of bipolar electrocoagulation and intracorporeal suture on the ovarian reserve after ovarian cystectomy. Sixty patients aged 18-42 years old and with a persistent adnexal mass were recruited to the study. Patients were randomized into suture hemostasis group or bipolar hemostasis group. Laparoscopic ovarian cystectomy was performed to all patients. Hemostasis was obtained by bipolar coagulation in 30 patients and by intracorporeal sutures in 30 patients. Serum levels of FSH, LH, estradiol, inhibin B and ultrasonographic measurements (antral follicle count and ovarian volume) were analyzed and recorded at day 3 of menstrual cycle, 1 and 3 months after the surgery. Basal FSH level measurement at the postoperative third month was significantly increased to 6.96 ± 1.86 mIU/ml (p < 0.05) in the bipolar electrocoagulation group. However, the decreased ovarian volume and antral follicle count was restored at the postoperative third month in the bipolar electrocoagulation group. Preoperative and postoperative FSH, LH, estradiol and inhibin B levels and ultrasonographic measurements were similar in the intracorporeal suture group. The unwanted effect of bipolar electrocoagulation on ovarian reserve is probably transient and causes minimal damage to ovary. FSH levels may be slightly elevated. Gentle use of bipolar electrocoagulation or intracorporeal are not found to effect ovarian reserve.

The 2016 Food and Drug Administration draft guidance describes the use of a rapid test (RT) to enhance platelet transfusion safety and availability. This study reports a 113-month experience of screening of apheresis platelets (APs) by RT. From July 2008 to October 2015, all APs underwent an RT on Day 4. Day 6 and 7 units were transfused with transfusion medicine physician approval. Any units remaining on Day 8 had a second RT performed. From November 2015 to November 2017, APs underwent an RT on Day 5 with a repeat RT on Days 6 and 7. During both periods, positive RTs underwent confirmatory testing with culture when repeat testing was positive. A total of 9009 APs underwent an RT on Day 4 or 5. Of these, 45 (0.5%) were RT positive, with no true positives. A total of 754 underwent a second RT on Day 8, with no positives. Since November 2015, 1152 platelets have undergone a second RT on Day 6; 391 have undergone a third RT on Day 7. Of these, five (0.4%) were RT positive on Day 6, with no true positives. There were no septic transfusion reactions identified by passive surveillance at our institution during either study period. To date, we have not detected any true positives after performing 11,306 tests on 9009 APs. A total of 1906 underwent testing twice, and 391 underwent testing three times. We did not identify any conversions from negative to positive on repeat testing. © 2018 AABB.

PURPOSE The Affordable Care Act (ACA) is expected to provide coverage for nearly twenty-five million previously uninsured individuals. Because the potential impact of the ACA for urological care remains unknown, we estimated the impact of insurance expansion on the utilization of inpatient urological surgeries using Massachusetts (MA) healthcare reform as a natural experiment. METHODS We identified nonelderly patients who underwent inpatient urological surgery from 2003 through 2010 using inpatient databases from MA and two control states. Using July 2007 as the transition point between pre- and post-reform periods, we performed a difference-indifferences (DID) analysis to estimate the effect of insurance expansion on overall and procedure-specific rates of inpatient urological surgery. We also performed subgroup analyses according to race, income and insurance status. RESULTS We identified 1.4 million surgeries performed during the study interval. We observed no change in the overall rate of inpatient urological surgery for the MA population as a whole, but an increase in the rate of inpatient urological surgery for non-white and low income patients. Our DID analysis confirmed these results (all 1.0%, p=0.668; non-whites 9.9%, p=0.006; low income 6.6%, p=0.041). At a procedure level, insurance expansion caused increased rates of inpatient BPH procedures, but had no effect on rates of prostatectomy, cystectomy, nephrectomy, pyeloplasty or PCNL. CONCLUSIONS Insurance expansion in Massachusetts increased the overall rate of inpatient urological surgery only for non-whites and low income patients. These data inform key stakeholders about the potential impact of national insurance expansion for a large segment of urological care. PMID:25506058

2011-12-01

To report on the prevalence, surgical management, and outcome of urinary tract endometriosis (UTE) in a cohort of 221 patients undergoing laparoscopic surgery for severe endometriosis. UTE can cause significant morbidity, such as silent kidney or progressive renal function loss. Its frequency is underestimated and data on laparoscopic management are scarce. Between 2007 and 2010, 43 patients were eligible for this single-center, retrospective study. The inclusion criterion was the presence of UTE (ie, bladder and/or ureteral endometriosis). All patients were operated laparoscopically. The prevalence of UTE was 19.5% (43/221). There was no correlation between bladder and ureteral endometriosis (P >.05). Ureteral endometriosis was associated with patient's age (P <.01). Patients with bladder, but not ureteral, involvement complained more frequently about dysuria, hematuria, and urinary tract infections. Intraoperative and magnetic resonance imaging (MRI) findings revealed a moderate to good correlation. UTE was not associated with rectovaginal or bowel endometriosis, but rather with involvement of the uterosacral ligaments (P <.01). Twenty-two patients with bladder endometriosis were treated by mucosal skinning and 11 patients underwent partial cystectomy. Superficial ureteral excision was performed in 4 patients, whereas resection with ureteroureterostomy was done in 9 patients. There was no difference regarding the intra- and postoperative complications in patients with or without UTE. In severe pelvic endometriosis, involvement of the urinary tract is quite common. Laparoscopic management is feasible and safe. Because of the lack of specific symptoms, the preoperative diagnosis of ureteral endometriosis still remains a challenge. Pelvic MRI represents a useful preoperative diagnostic tool. Copyright © 2011 Elsevier Inc. All rights reserved.

Aim: Activation of muscarinic receptors on the detrusor smooth muscle is followed by contraction, which involves both myosin light chain kinase (MLCK) and Rho kinase (ROCK). The aim of this study was to determine the relative contributions of MLCK and ROCK to carbachol-induced contraction of human detrusor smooth muscle in vitro. Methods: Detrusor smooth muscle strips were prepared from the macroscopically unaffected bladder wall of patients underwent cystectomy. The strips were fixed in an organ bath, and carbachol or KCl-induced isometric contractions were measured by force transducers. Results: Addition of carbachol (0.4-4 μmol/L) into the bath induced concentration-dependent contractions of detrusor specimens, which was completely abolished by atropine (1 μmol/L). Pre-incubation of detrusor specimens with either the MLCK inhibitor ML-9 or the ROCK inhibitors HA1100 and Y-27632 (each at 10 μmol/L) significantly blocked carbachol-induced contractions as compared to the time-control experiments. Moreover, MLCK and ROCK inhibition were equally effective in reducing carbachol-induced contractions. The residual carbachol-induced contractions in the presence of both MLCK and ROCK inhibitors were significantly smaller than the contractions obtained when only one enzyme (either MLCK or ROCK) was inhibited, suggesting an additive effect of the two kinases. Interestingly, ROCK-mediated carbachol-induced contractions were positively correlated to the age of patients (r=o.52, P<0.05). Conclusion: Both MLCK and ROCK contribute to carbachol-induced contractions of human detrusor smooth muscle. ROCK inhibitors may be a new pharmacological approach to modulate human bladder hyperactivity. PMID:24122009

2015-05-01

Poor range of motion may decrease a patient's ability to participate in activities of daily living after total knee arthroplasty. Manipulation under anesthesia has been shown to improve range of motion; however, some patients have persistent stiffness even after manipulation. The goal of this study was to evaluate the outcomes and complications of patients who underwent a second manipulation under anesthesia for persistent stiffness after total knee arthroplasty. The review of surgical records of two joint arthroplasty surgeons identified 226 knees in 210 patients who underwent a manipulation under anesthesia for poor range of motion after total knee arthroplasty. Of these patients, 16 patients underwent a second manipulation under anesthesia. For patients undergoing two manipulations under anesthesia procedures, at latest follow up (mean 539 days), mean extension improved from 10.50° to 2.50° (p=0.001) and mean flexion improved from 87.50° to 112.69° (p=0.001) respectively. SF-12 scores were available for 12 of 16 knees with a mean score of 34.42. Two of 16 patients (12.5%) experienced a complication. Three of 16 (18.8%) patients who underwent a second manipulation required a revision arthroplasty procedure. In conclusion, a second manipulation under anesthesia can achieve functional range of motion that is sustained after total knee arthroplasty.

Purpose: Providing data on the late diagnosis and surgical treatment of patients who underwent surgery for total unilateral congenital cataract. Methods: Systematic retrospective review of the medical record of all patients between 0 and 16 years old with total unilateral congenital cataract who underwent surgery at Fundación Vision between January 2010 and July 2012. Results: Medical records of 37 patients (51 % females) were studied, age was 7.4 (± 4.9) years (average ± SD) and 62% lived on Departamento Central (the most populated region from Paraguay). A total of 97.3% patients underwent late surgical treatment and 86.5% received a late diagnosis. The average time elapsed between the diagnosis and the surgical treatment was one month, and 62.2% of the patients underwent surgery within six months from the diagnosis. Conclusion: This study evidences that most of the patients in our series had a late treatment as a result of a late diagnosis. Based on these results we recommend establishing strategies to improve the early detection and surgical treatment of the newborns.

Primary tracheoesophageal puncture and cricopharyngeal myotomy in stapler-assisted total laryngectomy.

To evaluate the utility of the hybrid tracheoesophageal puncture procedure in stapler-assisted laryngectomy. Patients who underwent total laryngectomy at a single institution from 2009 to 2015 were reviewed. The interventions assessed were surgical creation of a tracheoesophageal puncture and placement of a voice prosthesis. The outcomes measured included voicing ability and valve failure. Thirty-nine patients underwent total laryngectomy or pharyngolaryngectomy. Of these, nine underwent stapler-assisted laryngectomy; seven of the nine patients underwent concurrent stapler-assisted laryngectomy, cricopharyngeal myotomy and a hybrid tracheoesophageal puncture procedure. These seven patients were the focus of this review. Successful voicing and oral alimentation was achieved in all patients. Mean time to phonation was 30 days (range, 7-77 days) and mean time to first valve change was 90 days (range, 35-117 days). Primary tracheoesophageal puncture with concurrent voice prosthesis placement and cricopharyngeal myotomy is easily performed with stapler-assisted laryngectomy. The hybrid tracheoesophageal puncture procedure is a simple method that enables a single operator to achieve primary tracheoesophageal puncture and valve placement; in addition, it facilitates concurrent cricopharyngeal myotomy.

Due to the extreme rarity of primary intrapulmonary solitary fibrous tumours (SFTs), their clinical course, imaging characteristics, diagnosis, treatment and prognosis are poorly understood. The present study therefore assessed the diagnosis and management of primary intrapulmonary SFTs and systematically reviewed previously reported cases in the literature. A total of 5 patients who underwent resection for primary intrapulmonary SFTs were enrolled in the present study and their clinical course, tumour characteristics, management and survival were assessed in this retrospective study. Relevant studies regarding primary intrapulmonary SFTs were searched using PubMed and tumour characteristics, clinicopathologic features, therapeutic strategy and survival outcomes were reviewed. Of the 5 cases, all were males, with a mean age of 57.6 years (range, 37–68 years). All patients were asymptomatic and were identified incidentally on routine computed tomography examination. A total of 3 patients underwent thoracotomy and 2 patients underwent video-assisted thoracoscopic surgery. All tumours were completely resected. Postoperative haemorrhage occurred in 1 patient and he received surgical intervention for haemostasis. The average hospital stay was 15 (4–22) days, and no mortality occurred. The mean length of the postoperative follow-up was 37.6 (1–67) months. One patient was lost to follow-up, and 4 patients were asymptomatic. A total of 19 studies were identified from database searches. They included a total of 45 patients: Twenty-three males and 22 females (mean age, 59.4 years; range, 7–81 years). A total of 12 patients were asymptomatic, and pain and coughing were the major symptoms. Five, one, two, four, and 17 tumours occurred in the right upper lobe, right middle lobe, right lower lobe, left upper lobe and left lower lobe, respectively. A total of 39 patients underwent surgery, 1 patient underwent radiotherapy, and 1 patient underwent radiofrequency ablation. A total of 22 patients were followed up and the mean length of the postoperative follow-up was 48 (1–168) months. One patient was diagnosed with chest wall metastases, and 5 patients succumbed to mortality. To conclude, primary intrapulmonary SFTs are extremely rare and typically identified incidentally. The present findings indicated that the left lower lobe was the most common site location and complete surgical resection is a safe and effective treatment. PMID:29467886

Thirty-four patients (35 knees) underwent revision total knee arthroplasty using the press-fit technique. Minimum follow-up was one year (mean 2.2 years) with a maximum length of three years. Of 34 patients, 20 were women and 14 were men. There was one death due to causes not related to arthroplasty and one patient dropout. There were no cases in which further review was necessary. Patients who underwent revision had clinical and functional improvement demonstrated by the results of the KSS, results of the SF-36 quality of life questionnaire, through gains in range of motion and improved limb alignment. There was postoperative clinical and functional improvement in comparison to the preoperative status in revision total knee arthroplasty with press-fit cementless stem.

Total hip and knee replacment surgeries are characterized by severe postoperative pain. Local infiltration analgesia is proved to be very effective. However this method has not been widely used in Hungary. To evaluate the efficacy of the local infiltration analgesia with modified components in patients underwent total hip or knee replacement surgery. Data of 99 consecutive patients underwent primary total hip or knee replacement surgery were evaluated prospectively. In all the 99 surgeries modified local infiltration analgesia was applied. Postoperative pain reported on a visual analog scale was recorded as well as the need for further analgetics during the first 18 hours after surgery. The cost of the analgetic drugs was calculated. The control group comprised 97 consecutive patients underwent total hip or knee replacement, where local infiltration analgesia was not applied. Statistical analysis was done. Patients received local infiltration analgesia reported significantly less pain (p<0.001). The need for postoperatively given analgetics was almost 50% less, and the cost of all postoperative analgetics was 47% less than in the control group. In total hip and knee replacement surgeries the modified local infiltration analgesia decreases postoperative pain effectively and contribute to the early mobilization of the patients. Orv.

Although approximately 75% of bladder cancers are non-muscle invasive (NMIBC) at diagnosis, most research tends to focus on invasive disease (e.g., experiences related to radical cystectomy and urinary diversion). There is a lack of studies on quality of life, and especially qualitative research, in bladder cancer generally. As a result, relatively little is known about the experiences and needs of NMIBC patients. To understand patient experience, define care priorities, and identify targets for care improvement in NMIBC across the cancer continuum. Through focus groups, patients treated for NMIBC (stage

To evaluate whether there is a correlation between publicized health ranking systems and surgical outcomes after radical cystectomy (RC) in New York State (NYS). Using the Statewide Planning and Research Cooperative System, data were collected in an aggregated fashion per hospital for the 20 hospitals with the highest RC volume in NYS from 2009 to 2012. Hospital characteristics were obtained from the publicly available sources such as the Centers for Medicare and Medicaid Services. Publicized ranking systems evaluated included the US News & World Health Report for Urology ranking (USHR), Healthgrades (HG) score, and Consumer Reports (CR) safety ranking. Outcomes measured included mortality, readmissions, and causes of readmissions. CR safety scores were inversely associated with overall death at 90 days after surgery (R = -0.527, P = .030), number of readmissions (R = -0.608, P = .030), and readmissions because of surgical complications (R = -0.523, P = .031) on a Pearson correlation test. On Kendall rank tau test, USHR and HG were not associated with any outcome of interest, although the scores correlated with increasing RC volume. In our analysis of 20 hospitals with the highest RC volume in NYS, USHR and HG scores were not strongly associated with any clinical outcome after RC. CR performed well in comparison with USHR and HG. Nevertheless, better metrics are needed to compare hospitals and to incorporate curative rates for morbid surgeries. Copyright © 2015 Elsevier Inc.

Case 1 : A 48-year-old man presenting with gross hematuria was suspected to have a tumor located in the bladder dome. He was referred to our department for further examination and treatment. Cystoscopy showed a dome-shaped mass in the supravesical region. Computed tomography and magnetic resonance imaging indicated the possibility of urachal carcinoma and peritoneal dissemination. Therefore, partial cystectomy with urachal resection was performed. The intraoperative findings were disseminated peritoneal nodules and mucus entering the peritoneal cavity from the tumor. On pathological examination, the tumor was classified as a mucinous-type adenocarcinoma, and 6 courses of TS-1/cisplatin (CDDP) therapy were administered to the patient as adjuvant chemotherapy. To date (10 months since the surgery), there has been no disease progression. Case 2 : A 76-year-old woman was referred to our department with a finding of a tumor in the bladder dome during her detailed examination for lung tumors. Cystoscopy showed nodular tumors, indicating lung metastases of the urachal carcinoma. Therefore, partial cystectomy with urachal resection was performed. On pathological examination, the tumor was classified as an enteric-type adenocarcinoma, and 2 courses of TS-1/CDDP therapy were administered to the patient as adjuvant chemotherapy. However, due to the development of marked bone marrow depression, the drugs had to be discontinued. Nonetheless, the lung metastases markedly diminished in size. To date (9 months since the discontinuation of chemotherapy), there has been no disease progression.

Adenocarcinoma of the urinary bladder is a rare malignancy. Radical surgery is suggested as the best available treatment for early-stage disease, but there is currently no consensus on standard chemotherapy regimen for advanced stage. We assessed the feasibility and effect of neoadjuvant chemotherapy with gemcitabine and cisplatin (GC) plus S-1 for patients with locally advanced primary adenocarcinomas of the urinary bladder. Six patients with locally advanced urachal or non-urachal (n = 3, each) primary adenocarcinoma of the bladder were treated from October 2010 to October 2013 at a single center. All the patients were treated with 3 cycles (21d, each) of GC plus S-1 (gemcitabine, 1000 mg/m2, days 1 and 8; cisplatin, 70 mg/m2, day 2; and S-1, 50 mg bid, day 1-14). After neoadjuvant chemotherapy, patients with urachal cancer were treated with en bloc radical cystectomy and umbilectomy; the remaining 3 patients were treated with cystectomy. All patients successfully completed the neoadjuvant chemotherapy without serious side effects. Two patients were assessed as complete response, 2 as partial response, 1 as stable disease and 1 as progressive disease. Despite the limitations of a small study population, the GC plus S-1 regimen for locally advanced primary adenocarcinoma of the urinary bladder was effective, and facilitated the success of surgery to a certain extent. Short follow-up time was also a limitation of our study. More studies are needed to evaluate the results.

To describe our experience with the implementation and refinement of an enhanced recovery programme (ERP) for radical cystectomy (RC) and urinary diversion. To assess the impact on length of stay (LOS), complication and readmission rates. In all, 165 consecutive patients undergoing open RC (ORC) and urinary diversion between January 2008 and April 2013 were entered into an ERP. A retrospective case note review was undertaken. Outcomes recorded included LOS, time to mobilisation, complication rates within the first 30 days (Clavien-Dindo classification) and readmissions. All patients were successfully entered into the ERP. As enhanced recovery principles became embedded in the unit, LOS reduced from a mean of 14 days over the initial year of the ERP to a mean of 9.2 days. The complication rate was 6.6% for Clavien ≥3, and 43.5% for Clavien ≤2. The 30-day mortality rate was 1.2%. The 30-day readmission rate was 13.9%. In the most contemporary subset of 52 patients: the median time after ORC to sit out of bed, mobilise and open bowels was day 1, 2 and 6, respectively. The ERP described for patients undergoing ORC appears to be safe. Benefits include early feeding, mobilisation and hospital discharge. The ERP will continue to develop with the incorporation of advancing evidence and technology, in particular the introduction of robot-assisted RC. © 2013 The Authors.

Compared to the literature on other malignancies, data on quality of life (QoL) in bladder cancer are sparse. This study sought answers to the following questions: In what QoL domains do patients with bladder cancer differ from the general population? Do patients with radical cystectomy differ in QoL compared to those who received conservative treatment? Do patients with neobladder generally have better QoL compared to patients with other diversion methods? At the beginning of inpatient rehabilitation, N = 823 patients with bladder cancer were assessed. Data of a representative community sample (N = 2037) were used for comparison. The questionnaire EORTC QLQ-C30 was used to measure QoL. Multivariate linear regression models were computed to investigate differences between groups. Patients with both non-muscle invasive and muscle invasive bladder cancer reported significantly more problems and worse functioning than the general population. Radiotherapy is associated with clinically relevant more pain, dyspnoea, constipation, appetite loss and decreased social functioning while chemotherapy is associated more with dyspnoea. Cystectomy patients reported more fatigue, appetite loss and decreased role functioning. Male patients ≥70 years with conduit experienced more sleep and emotional problems. These effects of urinary diversion were not observed in women and younger patients. Patients with bladder cancer experience various QoL concerns at the beginning of inpatient rehabilitation. These problems can partly be explained by the type of treatment the patients receive. Type of urinary diversion is relevant for QoL in subgroups of patients.

The health economics of bladder cancer: an updated review of the published literature.

The purpose of this paper is to provide a current view of the economic burden of bladder cancer, with a focus on the cost effectiveness of available interventions. This review updates a previous systematic review and includes 72 new papers published between 2000 and 2013. Bladder cancer continues to be one of the most common and expensive malignancies. The annual cost of bladder cancer in the USA during 2010 was $US4 billion and is expected to rise to $US5 billion by 2020. Ten years ago, urinary markers held the potential to lower treatment costs of bladder cancer. However, subsequent real-world experiments have demonstrated that further work is necessary to identify situations in which these technologies can be applied in a cost-effective manner. Adjunct cytology remains a part of diagnostic standard of care, but recent research suggests that it is not cost effective due to its low diagnostic yield. Analysis of intravesical chemotherapy after transurethral resection of bladder tumor (TURBT), neo-adjuvant therapy for cystectomy, and robot-assisted laparoscopic cystectomy suggests that these technologies are cost effective and should be implemented more widely for appropriate patients. The existing literature on the cost effectiveness of bladder cancer treatments has improved substantially since 2000. The body of work now includes many new models, registry analyses, and real-world studies. However, there is still a need for new implementation guidelines, new risk modeling tools, and a better understanding of the empirical burden of bladder cancer.

For elderly or medically unfit patients with muscle-invasive bladder cancer, cystectomy or chemotherapy are contraindicated. This leaves radical radiotherapy as the only treatment option. It was the aim of this study to retrospectively analyze the treatment outcome and associated toxicity of conformal versus intensity-modulated radiotherapy (IMRT) using a focal simultaneous tumor boost for muscle-invasive bladder cancer in patients not suitable for cystectomy. One hundred eighteen patients with T2-4 N0-1 M0 bladder cancer were analyzed retrospectively. Median age was 80 years. Treatment consisted of either a conformal box technique or IMRT and included a simultaneous boost to the tumor. To enable an accurate boost delivery, fiducial markers were placed around the tumor. Patients were treated with 40 Gy in 20 fractions to the elective treatment volumes, and a daily tumor boost up to 55-60 Gy. Clinical complete response was seen in 87 % of patients. Three-year overall survival was 44 %, with a locoregional control rate of 73 % at 3 years. Toxicity was low, with late urinary and intestinal toxicity rates grade ≥ 2 of 14 and 5 %, respectively. The use of IMRT reduced late intestinal toxicity, whereas fiducial markers reduced acute urinary toxicity. Radical radiotherapy using a focal boost is feasible and effective for elderly or unfit patients, with a 3-year locoregional control of 73 %. Toxicity rates were low, and were reduced by the use of IMRT and fiducial markers.

To evaluate the association between tourniquet and total operative time during total knee arthroplasty and the occurrence of deep vein thrombosis. Seventy-eight consecutive patients from our institution underwent cemented total knee arthroplasty for degenerative knee disorders. The pneumatic tourniquet time and total operative time were recorded in minutes. Four categories were established for total tourniquet time: <60, 61 to 90, 91 to 120, and >120 minutes. Three categories were defined for operative time: <120, 121 to 150, and >150 minutes. Between 7 and 12 days after surgery, the patients underwent ascending venography to evaluate the presence of distal or proximal deep vein thrombosis. We evaluated the association between the tourniquet time and total operative time and the occurrence of deep vein thrombosis after total knee arthroplasty. In total, 33 cases (42.3%) were positive for deep vein thrombosis; 13 (16.7%) cases involved the proximal type. We found no statistically significant difference in tourniquet time or operative time between patients with or without deep vein thrombosis. We did observe a higher frequency of proximal deep vein thrombosis in patients who underwent surgery lasting longer than 120 minutes. The mean total operative time was also higher in patients with proximal deep vein thrombosis. The tourniquet time did not significantly differ in these patients. We concluded that surgery lasting longer than 120 minutes increases the risk of proximal deep vein thrombosis.

The goal of the study was to determine the role of routine total thyroidectomy and hemithyroidectomy in patients undergoing total laryngectomy for laryngeal squamous cell carcinoma. The study group consisted of 343 patients who underwent total laryngectomy (98 treated with surgery alone, 136 treated following radiation failure, and 109 following chemoradiation failure). Total thyroidectomy was performed in all obstructing and bilateral lesions or if there was suspicion of contralateral lobe involvement. Hemithyroidectomy was performed in all lateralized lesions. Retrospective histopathologic analysis of thyroid specimens was subsequently performed. In all, 262 patients underwent total thyroidectomy during total laryngectomy, six of which demonstrated squamous cell carcinoma evident within the thyroid gland (4 from transglottic lesions, 2 from subglottic lesions). Hemithyroidectomy was performed in 81 patients, with only one patient demonstrating evidence of squamous cell carcinoma within the thyroid gland. Hypothyroidism was observed in 88% (n = 61) of patients who underwent thyroid lobectomy alone, requiring hormone supplementation. Routine surgical management of the thyroid gland should not be performed, except in cases of subglottic primary lesions, lesions with significant subglottic extension, or transglottic lesions. Despite efforts to preserve the contralateral thyroid lobe in cases of selective lobectomy, these patients often have a high rate of hypothyroidism, and a total thyroidectomy should be considered when involvement of the thyroid gland is suspected.

Bronchobiliary fistula is a rare and is an uncommon but severe complication of hydatid disease of the liver. Treatment has traditionally been surgical resection, but embolization and stent placement have been described. The invasive method seems to be a key component of patient treatment. We describe a case of a 58-year-old woman who, 25 years before, had undergone surgery for a hydatid cyst. A total cystectomy without previous puncture or parasite extraction was carried out. The lower aspect of the cyst was found to be completely perforated over the biliary duct. During the postoperative course, the patient had subphrenic right-sidedmore » pleural effusion and biliary fistula that subsided with medical treatment. Afterward, the patient came to the outpatient area of our hospital complaining of leakage of purulent exudate through the cutaneous opening, pain located on the right hypochondrium radiating to the right hemithorax, malaise, fever, chronic cough, and occasional vomiting of bile. Fistulography revealed an anfractuous cavity communicating with a residual cystic cavity on the right hepatic lobe. We observed communication with the intrahepatic canaliculi. Computed tomographic scan revealed a fistulous tract on the anterior liver border through the abdominal wall. There were no posttreatment complications. The patient is asymptomatic.« less

Cancer Committee of the French Association of Urology (CCAFU) conducted a review of the epidemiology, diagnosis and treatment of intradiverticular bladder tumours (TVID) and proposed therapeutic management. A bibliographic research in French and English using Medline(®) with the keywords "tumor", "bladder" and "diverticulum" was performed. TVID are more frequently of stage T ≥ 3a and with non urothelial histology than classical bladder tumors. At diagnosis, the risk of underestimation of the extent and multifocality of the tumor was described. Their prognosis, that was more pejorative than conventional tumors, should impelled to limit the indications of conservative treatment. The evidence levels of analyzed publications were low, with C level according to Sackett score. the specificities of the TVID have lead the CCAFU to propose specific therapeutic guidelines, based on poor evidence level. Ta-T1 low grade TVID can be treated by transurethral resection alone or followed by BCG therapy in cases of associated carcinoma in situ. High-grade TVID, unifocal and without associated carcinoma in situ, can be treated by diverticulectomy associated with pelvic lymphadenectomy. High grade TVID, multiple or associated with carcinoma in situ, warranted total cystectomy. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

Background and Objectives: The purpose of this study was to evaluate the feasibility and validity of a dedicated da Vinci single-port platform in the porcine model in the performance of gynecologic surgery. Methods: This pilot study was conducted in 4 female pigs. All pigs had a general anesthetic and were placed in the supine and flank position. A 2-cm umbilical incision was made, through which a robotic single-port device was placed and pneumoperitoneum obtained. A data set was collected for each procedure and included port placement time, docking time, operative time, blood loss, and complications. Operative times were compared between cases and procedures by use of the Student t test. Results: A total of 28 surgical procedures (8 oophorectomies, 4 hysterectomies, 8 pelvic lymph node dissections, 4 aorto-caval nodal dissections, 2 bladder repairs, 1 uterine horn anastomosis, and 1 radical cystectomy) were performed. There was no statistically significant difference in operating times for symmetrical procedures among animals (P=0.3215). Conclusions: This animal study demonstrates that single-port robotic surgery using a dedicated single-site platform allows performing technically challenging procedures within acceptable operative times and without complications or insertion of additional trocars.

ABSTRACT Purpose To examine the safety and efficacy of hyperbaric oxygen as the primary and sole treatment for severe radiation-induced haemorrhagic cystitis. Materials and methods Hyperbaric oxygen was prospectively applied as primary treatment in 38 patients with severe radiation cystitis. Our primary endpoint was the incidence of complete and partial response to treatment, while the secondary endpoints included the duration of response, the correlation of treatment success-rate to the interval between the onset of haematuria and initiation of therapy, blood transfusion need and total radiation dose, the number of sessions to success, the avoidance of surgery and the overall survival. Results All patients completed therapy without complications with a mean follow-up of 29.33 months. Median number of sessions needed was 33. Complete and partial response rate was 86.8% and 13.2%, respectively. All 33 patients with complete response received therapy within 6 months of the haematuria onset. One patient needed cystectomy, while 33 patients were alive at the end of follow-up. Conclusions Our study suggests the early primary use of hyperbaric oxygen for radiation-induced severe cystitis as an effective and safe treatment option. PMID:28338304

A case of moving ileal Taenia saginata parasites is presented with demonstrative images. We came across the parasites surprisingly while performing robot-assisted laparoscopic radical cystoprostatectomy with intracorporeal Studer pouch urinary diversion. We recommend stool sample evaluation in the preoperative period for possible presence of intestinal parasitic diseases, particularly in patients with bladder cancer who are admitted from areas with an increased incidence of intestinal parasitic diseases, before opening the bowel segments during surgery to perform radical cystectomy and urinary diversion.

Bladder cancer is the fourth most common cancer among European males. Once diagnosed with muscle invasive bladder cancer, a radical cystectomy is the first line treatment, which results in a urostomy. The placement of a urostomy and the care required impacts the patient's life. Previous research validated the Urostomy Education Scale as the first standardized tool capable of documenting the patients' level of stoma self-care skills and useful to guide patient education interventions. A Danish-Dutch Fellowship was established to support and provide further evidence of applicability of the Urostomy Education Scale.

SMILE and Wavefront-Guided LASIK Out-Compete Other Refractive Surgeries in Ameliorating the Induction of High-Order Aberrations in Anterior Corneal Surface

PubMed Central

2016-01-01

Purpose. To compare the change of anterior corneal higher-order aberrations (HOAs) after laser in situ keratomileusis (LASIK), wavefront-guided LASIK with iris registration (WF-LASIK), femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK), and small incision lenticule extraction (SMILE). Methods. In a prospective study, 82 eyes underwent LASIK, 119 eyes underwent WF-LASIK, 88 eyes underwent FS-LASIK, and 170 eyes underwent SMILE surgery. HOAs were measured with Pentacam device preoperatively and 6 months after surgery. The aberrations were described as Zernike polynomials, and analysis focused on total HOAs, spherical aberration (SA), horizontal coma, and vertical coma over 6 mm diameter central corneal zone. Results. Six months postoperatively, all procedures result in increase of anterior corneal total HOAs and SA. There were no significant differences in the induced HOAs between LASIK and FS-LASIK, while SMILE induced fewer total HOAs and SA compared with LASIK and FS-LASIK. Similarly, WF-LASIK also induced less total HOAs than LASIK and FS-LASIK, but only fewer SA than FS-LASIK (P < 0.05). No significant difference could be detected in the induced total HOAs and SA between SMILE and WF-LASIK, whereas SMILE induced more horizontal coma and vertical coma compared with WF-LASIK (P < 0.05). Conclusion. FS-LASIK and LASIK induced comparable anterior corneal HOAs. Compared to LASIK and FS-LASIK, both SMILE and WF-LASIK showed advantages in inducing less total HOAs. In addition, SMILE also possesses better ability to reduce the induction of SA in comparison with LASIK and FS-LASIK. However, SMILE induced more horizontal coma and vertical coma compared with WF-LASIK, indicating that the centration of SMILE procedure is probably less precise than WF-LASIK. PMID:27818792

Inflammation and necrosis have been associated with prognosis in multiple epithelial malignancies. Our objective was to evaluate inflammation and necrosis in a cohort of patients with high-grade urothelial carcinomas of the bladder to determine their association with pathological parameters and their prognostic effect on relapse-free and disease-specific survival. A retrospective cohort that underwent radical cystectomy for urothelial carcinomas (n=235) was evaluated for invasive front and central inflammation using the Klintrup-Makinen assessment method. Necrosis was scored using a four-point scale. The relationship of inflammation and necrosis with stage, nodal status, carcinoma in situ, tumour size, margin status and vascular space invasion and the impact on relapse-free and disease-specific survival were calculated using appropriate statistical tests. On multivariate analysis, invasive front inflammation (p=0.003) and necrosis (p=0.000) were independent predictors of relapse-free survival. Both invasive front inflammation (p=0.009) and necrosis (p=0.002) again were independent predictors of disease-specific survival. For pathological features, low invasive front inflammation was associated with lymphovascular space invasion (p=0.008), a positive soft tissue margin (p=0.028) and carcinoma in situ (p=0.042). Necrosis was statistically associated with tumours >3 cm in size (p=0.013) and carcinoma in situ (p<0.001). Necrosis and invasive front inflammation are additional histological variables with independent prognostic relevance in high-grade urothelial carcinoma of the bladder. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Purpose: To report the success of groin nodal lymphography in the diagnosis and treatment of genital lymphedema. Methods and Materials: We present one female (8 years old [patient no. 1]) and two male (69 and [patient no. 2] 31 years old [patient no. 3], respectively) patients with genital lymphedema in whom conservative treatment failed. The girl also had lymphorrhagia. Genital lymphedema was caused by radical cystectomy (patient no. 2), lymphatic hyperplasia (patient no. 1), and idiopathic lymphangitis (patient no. 3). All of them underwent ultrasound-guided bilateral groin lymph node puncture. Afterward, 4-8 ml Lipiodol Ultra-Fluide (Guerbet) were injected at amore » rate of 0.2 ml/s. Lipiodol progression was assessed by fluoroscopy. Computed tomography scan of the abdomen and pelvis was performed immediately after and again at 24 h after the procedure to confirm the leak. The follow-up period was 15, 13, and 9 months, respectively. Technical success was considered as bilateral pelvic and abdominal filling of lymphatic vessels. Therapeutic success was considered as improvement or disappearance of genital lymphedema and/or lymphorrhagia. Results: Lipiodol leak to the scrotum was observed in patients no. 2 and 3. Lymphaticopelvic fistula and genital lymphatic hyperplasia were seen in patient no. 1. Genital lymphedema diminished within 1 week and almost disappeared in two cases (patients no. 1 and 3) or significantly improved (patient no. 2). lymphorrhagia also resolved in patient no. 1. No recurrence or worsening was detected during follow-up. Conclusion: Therapeutic lymphangiography by lymph node injection seems to be effective to treat genital lymphedema. Lymph node puncture lymphangiography is feasible and less cumbersome than pedal lymphangiography.« less

To analyse survival in patients with clinically localised, surgically resectable micropapillary bladder cancer (MPBC) undergoing radical cystectomy (RC) with and without neoadjuvant chemotherapy (NAC) and develop risk strata based on outcome data. A review of our database identified 103 patients with surgically resectable (≤cT4acN0 cM0) MPBC who underwent RC. Survival estimates were calculated using Kaplan-Meier method and compared using log-rank tests. Classification and regression tree (CART) analysis was performed to identify risk groups for survival. For the entire cohort, estimated 5-year overall survival and disease-specific survival (DSS) rates were 52% and 58%, respectively. CART analysis identified three risk subgroups: low-risk: cT1, no hydronephrosis; high-risk: ≥cT2, no hydronephrosis; and highest-risk: cTany with tumour-associated hydronephrosis. The 5-year DSS for the low-, high-, and highest-risk groups were 92%, 51%, and 17%, respectively (P < 0.001). Patients down-staged at RC

The purpose of this study was to determine if 3D-rendered CT urography (CTU) depicts both normal and abnormal findings in patients with urinary diversions and if the addition of contrast-enhanced CT digital radiography (CTDR) improves opacification of the urinary collecting system. Thirty CTU and contrast-enhanced CTDR examinations were performed in 24 patients who underwent cystectomy for bladder cancer. Indications for evaluation included hematuria, tumor surveillance, or suspected diversion malfunction. All examinations were evaluated without knowledge of the stage or grade of a patient's tumor and were compared with the clinical records. Opacification of the urinary collecting system was evaluated with 3D CTU alone, contrast-enhanced CTDR alone, and combined CTU and CTDR. Nine abnormalities were identified including distal ureteral strictures (n = 4), vascular compression of the mid left ureter (n = 1), scarring of the mid right pole infundibulum (n = 1), bilateral hydronephrosis and hydroureter (n = 1), urinary reservoir calculus (n = 1), and tumor recurrence invading the afferent limb of the neobladder (n = 1). Eight of the nine detected abnormalities were surgically or pathologically confirmed. All abnormalities were identified on all three imaging techniques but were best seen on 3D CTU and enhanced CTDR images. Incomplete opacification of the urinary collecting system occurred in 17 patients with CTU alone, 12 patients with contrast-enhanced CTDR alone, and nine patients with combined CTU and contrast-enhanced CTDR. Compared with CTU alone, the combined technique of 3D CTU and contrast-enhanced CTDR improved opacification by a statistically significant difference (p = 0.037). CTU with 3D rendering can accurately depict both normal and abnormal postoperative findings in patients with urinary diversions. Adding enhanced CTDR can improve visualization of the urinary collecting system.

To explore the function of NORAD in bladder cancer (BC), and to verify whether NORAD could be used as a biomarker to determine preoperative presence of progression and lymph node metastasis. To our knowledge, it is the first study investigating NORAD and its implications in BC. BC specimens of 90 patients underwent bladder cystectomy or transurethral resection between January 2012 to December 2016 were tested by fluorescence in situ hybridization. The association between NORAD expression and clinicopathological features and prognosis of the patients was analyzed using Kaplan-Meier survival analysis and Cox regression analysis. Quantitative real-time polymerase chain reaction was performed in 4 BC cell lines and 10 fresh tumor sample together with adjacent tissues. MTT, colony formation assay, and Annexin-V apoptosis detection were performed after knockdown of NORAD using shRNA in TSSCUP cells. Western blot was performed to related proteins extracted from these cells. Fluorescence in situ hybridization indicated that high NORAD expression was associated with more advanced histological grade and clinical stage for patients with BC. Higher NORAD expression resulted in lower overall survival, and was an independent prognostic indicator. Real-time polymerase chain reaction showed that the expression of NORAD in BC tissues was higher than those measured in adjacent normal tissues. MTT and colony formation assay demonstrated that knockdown of NORAD results in lower proliferation in TSSCUP cells, whereas PUM2 expression was upregulated and E2F3 downregulated. High NORAD expression could serve as an independent prognostic factor for overall survival of patients with transitional BC. NORAD could be considered as a promising candidate for novel biomarker and therapeutic target for human BC. Copyright © 2018 Elsevier Inc. All rights reserved.

The purpose of this study was to compare the total hospital costs associated with elective laparoscopic and open inguinal herniorrhaphy. A prospectively maintained database was used to identify patients who underwent elective inguinal herniorrhaphy from April 2009 to March 2011. A retrospective review of electronic patient records was performed along with a standardized case-costing analysis using data from the Ontario Case Costing Initiative. The main outcomes were operating room (OR) and total hospital costs. Two hundred eleven patients underwent elective unilateral inguinal herniorrhaphy (117 open and 94 laparoscopic), and 33 patients underwent elective bilateral inguinal herniorrhaphy (9 open and 24 laparoscopic). OR and total hospital costs for open unilateral inguinal hernia repair were significantly lower than for the laparoscopic approach (median total cost, $3207.15 vs $3723.66; P < .001). OR and total hospital costs for repair of elective bilateral inguinal hernias were similar between the open and laparoscopic approaches (median total cost, $4574.02 vs $4662.89; P = .827). In the setting of a Canadian academic hospital, when considering the repair of an elective unilateral inguinal hernia, the OR and total hospital costs of open surgery were significantly lower than for the laparoscopic techniques. There was no statistical difference between OR and total hospital costs when comparing open surgery and laparoscopic techniques for the repair of bilateral inguinal hernias. Given the perioperative benefits of laparoscopy, further studies incorporating hernia-specific outcomes are necessary to determine the cost-effectiveness of each approach and to define the optimal treatment strategy.

To assess the long-term (20 years) effectiveness of the UroLume wallstent(TM) (Pfizer Inc., UK) in the treatment of detrusor external sphincter dyssynergia (DESD) in patients with spinal cord injury (SCI). Twelve patients with quadriplegia secondary to SCI underwent external striated sphincter stenting with the UroLume wallstent in place of sphincterotomy for DESD ≈ 20 years ago. The mean (range) age was 41.8 (26-65) years. Eleven patients had cervical level injury whilst one had a thoracic injury. All the patients were shown to have high-pressure neurogenic detrusor overactivity and DESD with incomplete emptying on preoperative video-cystometrograms (VCMG). Six of the 12 patients have now been followed-up for a mean (range) of 20 (19-21) years. Of the remaining six, two were lost to follow-up at 1 and 3 years, but both remained free of complications during that time. Two patients developed encrustation causing obstruction, requiring stent removal within 1 year of insertion. Another patient with an adequately functioning stent died 7 years after stent insertion from a chest infection. The twelfth patient developed bladder cancer 14 years after stent insertion and underwent cystectomy with urinary diversion. VCMG follow-up of the six patients showed a significantly sustained reduction of maximum detrusor pressure and duration of detrusor contraction at the 20-year follow-up. Five of these six patients developed bladder neck dyssynergia of varying degrees as shown on VCMG within the first 9 years of follow-up. All were successfully treated with bladder neck incision (BNI) where the last BNI needed was at 12 years. We did not encounter any problem with stent migration, urethral erosion, erectile dysfunction or autonomic dysreflexia. Urethral stenting using the UroLume wallstent is effective in the management of DESD in patients with SCI and provides an acceptable long-term (20-year follow-up) alternative to sphincterotomy. The failures manifest within the first few years and can be managed easily with stent removal without any significant problems. Bladder neck dyssynergia was the long-term complication which was treated successfully with BNI. It has no significant interference with erectile function, being reversible, minimally invasive and has a shorter hospital stay. © 2010 THE AUTHORS. JOURNAL COMPILATION © 2010 BJU INTERNATIONAL.

Robotic technology disseminated into urological practice without robust comparative effectiveness data. To review the diffusion of robotic surgery into urological practice. We performed a comprehensive literature review focusing on diffusion patterns, patient safety, learning curves, and comparative costs for robotic radical prostatectomy, partial nephrectomy, and radical cystectomy. Robotic urologic surgery diffused in patterns typical of novel technology spreading among practicing surgeons. Robust evidence-based data comparing outcomes of robotic to open surgery were sparse. Although initial Level 3 evidence for robotic prostatectomy observed complication outcomes similar to open prostatectomy, subsequent population-based Level 2 evidence noted an increased prevalence of adverse patient safety events and genitourinary complications among robotic patients during the early years of diffusion. Level 2 evidence indicated comparable to improved patient safety outcomes for robotic compared to open partial nephrectomy and cystectomy. Learning curve recommendations for robotic urologic surgery have drawn exclusively on Level 4 evidence and subjective, non-validated metrics. The minimum number of cases required to achieve competency for robotic prostatectomy has increased to unrealistically high levels. Most comparative cost-analyses have demonstrated that robotic surgery is significantly more expensive than open or laparoscopic surgery. Evidence-based data are limited but suggest an increased prevalence of adverse patient safety events for robotic prostatectomy early in the national diffusion period. Learning curves for robotic urologic surgery are subjective and based on non-validated metrics. The urological community should develop rigorous, evidence-based processes by which future technological innovations may diffuse in an organized and safe manner.

The aim of this study is to access the feasibility, toxicity profile, and tumour outcome of an organ preservation curative approach in non-metastatic muscle-invasive bladder cancer. A retrospective analysis was conducted on patients affected by M0 bladder cancer, who refused cystectomy and were treated with a curative approach. The standard bladder preservation scheme included maximal transurethral resection of bladder tumour (TURBT) and combination of radiotherapy and platin-based chemotherapy, followed by endoscopic evaluation, urine cytology, and instrumental evaluation. Thirteen patients fulfilled the inclusion criteria. TNM stage was cT2cN0M0 and cT2cNxM0, in 12 and one patients, respectively. All patients had transitional cell cancer. Twelve patients completed the whole therapeutic programme (a bimodal treatment without chemotherapy for one patient). Median follow-up is 36 months. None of the patients developed severe urinary or intestinal acute toxicity. In 10 patients with a follow-up > 6 months, no cases of severe late toxicity were observed. Response evaluated in 12 patients included complete response and stable disease in 11 patients (92%), and one patient (8%), respectively. At the time of data analysis (March 2016), 10 patients (77%) are alive with no evidence of disease, two patients (15%) died for other reasons, and one patient has suspicious persistent local disease. The trimodality approach, including maximal TURBT, radiotherapy, and chemotherapy for muscle-invasive bladder cancer, is well-tolerated and might be considered a valid and feasible option in fit patients who refuse radical cystectomy.

Pheochromocytoma of the urinary bladder: a systematic review of the contemporary literature

PubMed Central

2013-01-01

Background Pheochromocytoma (paraganglioma) of the urinary bladder is a rare tumor. Herein we sought to review the contemporary literature on pheochromocytomas of the urinary bladder in order to further illustrate the presentation, treatment options and outcomes of patients diagnosed with these tumors. Methods A comprehensive review of the current literature was conducted according to the PRISMA guidelines by accessing the NCBI PubMed database and using the search terms “paraganglioma, pheochromocytoma, bladder.” This search resulted in the identification of 186 articles published between January 1980 and April 2012 of which 80 articles were ultimately included in our analysis. Results Pheochromocytomas usually occurred in young adult Caucasians (mean age, 43.3 years; range,11–84 years). According to the literature, the most common symptoms and signs of pheochromocytomas of the urinary bladder were hypertension, headache, and hematuria. Of the 77 cases that commented on catecholamine production, 65 patients had biochemically functional tumors. Approximately 20% of patients were treated by transurethral resection alone, 70% by partial cystectomy and 10% by radical cystectomy. The 75 patients with follow-up information had a mean follow-up of 35 months. At the time of last follow-up, 15 (14.2%) had disease recurrence, 10 (9.4%) had metastasis, and 65 (61.3%) were alive. Conclusions Pheochromocytomas of the urinary bladder tend to be functional and occur mostly in young adult Caucasians. Patients with localized tumors have an extremely favorable prognosis and may be managed by less aggressive modalities, whereas patients with metastatic disease have a significant reduction in survival rates despite aggressive treatment.

Approximately 12,000 people are diagnosed with invasive transitional cell carcinoma of the urinary bladder (InvTCC) each year in the United States. Surgical removal of the bladder (cystectomy) and regional lymph node dissection are considered frontline therapy. Cystectomy causes extensive acute morbidity, and 50% of patients with InvTCC have occult metastases at the time of diagnosis. Better staging procedures for InvTCC are greatly needed. This study was performed to evaluate an intra-operative near infrared fluorescence imaging (NIRF) system (Frangioni laboratory) for identifying sentinel lymph nodes draining InvTCC. NIRF imaging was used to map lymph node drainage from specific quadrants of the urinary bladder in normal dogs and pigs, and to map lymph node drainage from naturally-occurring InvTCC in pet dogs where the disease closely mimics the human condition. Briefly, during surgery NIR fluorophores (human serum albumen-fluorophore complex, or quantum dots) were injected directly into the bladder wall, and fluorescence observed in lymphatics and regional nodes. Conditions studied to optimize the procedure including: type of fluorophore, depth of injection, volume of fluorophore injected, and degree of bladder distention at the time of injection. Optimal imaging occurred with very superficial injection of the fluorophore in the serosal surface of the moderately distended bladder. Considerable variability was noted from dog to dog in the pattern of lymph node drainage. NIR fluorescence was noted in lymph nodes with metastases in dogs with InvTCC. In conclusion, intra-operative NIRF imaging is a promising approach to improve sentinel lymph node mapping in invasive urinary bladder cancer.

Effectiveness of a cranberry (Vaccinium macrocarpon) preparation in reducing asymptomatic bacteriuria in patients with an ileal enterocystoplasty.

Bacteriuria is a usual complication of enterocystoplasty following cystectomy. Cranberry products may decrease the number of urinary tract infections because of a non-dialysable compound, a condensed tannin, the proanthocyanidin (PAC) type A. This study determined the effectiveness of treatment with a cranberry preparation highly dosed in proanthocyanidin A in prevention of repeated bacteriuria in patients with an ileal enterocystoplasty. Between November 2004 and November 2009, a controlled study was open to patients seen in consultation for follow-up after a radical cystectomy and ileal cystoplasty. Patients had a history of repeated urinary infection and/or bacteriuria during the pretreatment phase. During the treatment phase, patients received a cranberry (Vaccinium macrocarpon) preparation highly dosed in proanthocyanidin A (36 mg measured by the dimethylaminocinnamaldehyde method), one capsule a day. The primary endpoint was the absence of bacteria in urine culture. The secondary endpoints were the presence or absence of symptoms (pain, fever), continence status and upper excretory tract enlargement. Each patient was his or her own historical control. Fifteen patients were included. The median duration of the period without treatment with cranberry compound was 18.5 (1-93) months. The median duration of the period with treatment with cranberry compound was 32.8 (13-60) months. There was a significant decrease in the number of positive urine cultures during cranberry compound treatment. Treatment with a cranberry compound seems to be effective in reducing asymptomatic bacteriuria in patients with an ileal enterocystoplasty. These results need to be validated by further double-blind randomized studies.

To evaluate the usage of unidirectional barbed suture and its related implications in various surgeon-controlled robotic reconstructive urologic surgeries. From March 2010 to March 2011, all patients undergoing various surgeon-controlled robotic reconstructive urologic surgeries utilizing barbed sutures were prospectively enrolled in this study. Type and number of procedure performed were noted. Intraoperative and peri-operative outcomes potentially related to suture technique and material were recorded. This study reports on 210 patients, in whom barbed suture was used during this period. These included partial nephrectomy (20), pyeloplasty (9), ureteric tailoring and reimplantation (1), closure of bladder after Nephroureterectomy with excision of bladder cuff (8), closure of vaginal cuff in female radical cystectomy (12), partial cystectomy (1), radical prostatectomy (152), simple prostatectomy (2), vesicovaginal fistula repair (3), sacrocolpopexy (1), and hernia repair (1). We encountered 5 instances (2.38%) of tissue cut through possibly attributable to the use of barbed suture and 4 instances of misplacement of suture occurred, of these two required a new suture, whereas retrograde pull back of suture and needle was performed in 2 cases. No instance of slip back/loosening of suture was noted once it was tightened. At mean follow-up of 6.8 (1-14 months) months, we did not encounter any complications of urinary leakage, stone formation or fistula or any clinical evidence of urinary tract obstruction due to the use of barbed suture. Use of unidirectional barbed suture is safe, feasible, and efficient at short-term follow-up for reconstructive part of urological procedures.

To evaluate health-related quality of life (HR-QoL) outcomes in elderly patients with different type of urinary diversion (UD), ileal conduit (IC) and ileal orthotopic neobladder (IONB), after radical cystectomy (RC) for bladder cancer, by using validated self-reported cancer-specific instruments. We retrospectively reviewed 77 patients who received an IC or an IONB after RC. HR-QoL was assessed with specific and validated disease questionnaires, administered at last follow-up. At univariate analysis, at a mean follow-up of 60.91 ± 5.63 months, IONB results were favourable with regard to the following HR-QoL aspects: nausea and vomiting (p = 0.045), pain (p = 0.049), appetite loss (p = 0.03), constipation (p = 0.000), financial impact (p = 0.012) and cognitive functioning (p = 0.000). This last functional aspect was significantly worse in female patients (p = 0.029). Emotional functioning was significantly better in patients without long-term complications (p = 0.016). At multivariate analysis, male gender and IONB were independent predictors of better cognitive functioning, while long-term complications negatively affected emotional functioning. Obtained results suggest that an IONB can also be suitable for elderly patients compared with an IC with few and selected advantages in favour of the former UD. Preoperative patient's selection, counselling, education and active participation in the decision-making process lead to a more suitable choice of treatment. © 2018 S. Karger AG, Basel.

Postoperative ileus (POI) is common following bowel resection for radical cystectomy with ileal conduit (RCIC). We investigated perioperative factors associated with prolonged POI following RCIC, with specific focus on opioid-based analgesic dosage. From March 2007 to January 2013, 78 open RCICs and 26 robot-assisted RCICs performed for bladder carcinoma were identified with adjustment for age, gender, American Society of Anesthesiologists grade, and body mass index (BMI). Perioperative records including operative time, intraoperative fluid excess, estimated blood loss, lymph node yield, and opioid analgesic dose were obtained to assess their associations with time to passage of flatus, tolerable oral diet, and length of hospital stay (LOS). Prior to general anaesthesia, patients received epidural patient-controlled analgesia (PCA) consisted of fentanyl with its dose adjusted for BMI. Postoperatively, single intravenous injections of tramadol were applied according to patient desire. Multivariate analyses revealed cumulative dosages of both PCA fentanyl and tramadol injections as independent predictors of POI. According to surgical modality, linear regression analyses revealed cumulative dosages of PCA fentanyl and tramadol injections to be positively associated with time to first passage of flatus, tolerable diet, and LOS in the open RCIC group. In the robot-assisted RCIC group, only tramadol dose was associated with time to flatus and tolerable diet. Compared to open RCIC, robot-assisted RCIC yielded shorter days to diet and LOS; however, it failed to shorten days to first flatus. Reducing opioid-based analgesics shortens the duration of POI. The utilization of the robotic system may confer additional benefit.

To compare the clinical outcomes of sigmoid and ileal neobladders (NBs) created following radical cystectomy. This study included 90 and 144 Japanese patients undergoing radical cystectomy and orthotopic NB reconstruction with a sigmoid and ileal segment, respectively. Postoperative clinical outcomes between the sigmoid and ileal NB groups (SNBG and INBG) were compared. In this series, 110 early and 51 late complications occurred in 71 and 41 patients, respectively; however, there was no significant difference in the incidence of complications between SNBG and INBG. At 1 year postoperatively, there were no significant differences in the proportion of spontaneous voiders and the continence status between these 2 groups; however, despite the lack of significant differences in the maximal flow rate and voided volume, the post-void residual in SNBG was significantly smaller than that in INBG. Voiding functional outcomes at 5 years postoperatively were also obtained from 28 and 49 in SNBG and INBG, respectively. Although there were no significant changes in the functional outcomes in SNBG, the proportion of spontaneous voiders and post-void residual in INBG at 5 years postoperatively were significantly poorer than those at 1 year postoperatively. Furthermore, the postoperative health-related quality of life assessed by a Short-Form 36 survey did not show any significant differences in all 8 scores between these 2 groups. Both types of NB reconstruction resulted in comparatively satisfactory outcomes; however, the voiding function, particularly that on long-term follow-up, in SNBG appeared to be more favorable than that in INBG.

Bladder cancer.

Bladder cancer is a common and chemotherapy-responsive tumor, related to tobacco smoking, environmental arsenic exposure, industrial dye exposure, and parasitic schistosomiasis exposure. Both reduction of carcinogen exposure and chemoprevention, possibly with cyclooxygenase 2 inhibitors, should reduce the incidence. The search for the ideal screening and monitoring test continues with some promising new candidates, including survivin. Although 10-year survival can be achieved in 87% of early-stage patients with muscle-invasive disease rendered T(0) and 57% of those rendered T(1) at second look after transurethral resection bladder tumor, most still require radical cystectomy. Continued improvements in surgical techniques permit gains in quality of life after the procedure. Ten-year survival can still be achieved with cystectomy in the face of grossly positive lymph nodes in 32% of T(2) and 10% of T(3) patients. A recent meta-analysis indicates that preoperative irradiation is unlikely to be beneficial, but definitive chemoradiation can produce significant 5-year survival rates in nonoperative candidates and those desiring bladder preservation. The Intergroup now has preliminary data from a Southwest Oncology Group-based trial showing a significant benefit for neoadjuvant methotrexate, vinblastine, doxorubicin, and cisplatin. The regimen of gemcitabine and cisplatin is equally efficacious with less toxicity than methotrexate, vinblastine, doxorubicin, and cisplatin. It has been adopted as the standard arm in a phase III trial for advanced bladder cancer, comparing it with the triplet of gemcitabine, paclitaxel, and cisplatin. Other active agents in bladder cancer include ifosfamide, carboplatin, docetaxel, and vinorelbine, and various doublets of these agents are being tested in phase II trials, with promising results.

Background and Objectives: Conversion to open surgery is an important problem, especially during the learning curve of laparoscopic totally extraperitoneal (TEP) inguinal hernia repair. Methods: Here, we discuss conversion to the Stoppa procedure during laparoscopic TEP inguinal hernia repair. Outcomes of patients who underwent conversion to an open approach during laparoscopic TEP inguinal hernia repair between September 2004 and May 2010 were evaluated. Results: In total, 259 consecutive patients with 281 inguinal hernias underwent laparoscopic TEP inguinal hernia repair. Thirty-one hernia repairs (11%) were converted to open conventional surgical procedures. Twenty-eight of 31 laparoscopic TEP hernia repairs were converted to modified Stoppa procedures, because of technical difficulties. Three of these patients underwent Lichtenstein hernia repairs, because they had undergone previous surgeries. Conclusion: Stoppa is an easy and successful procedure used to solve problems during TEP hernia repair. The Lichtenstein procedure may be a suitable option in patients who have undergone previous operations, such as a radical prostatectomy. PMID:23477173

The efficacy of total colonoscopy following a positive result of the fecal occult blood test (FOBT) for the early detection of colorectal cancer and polyps was evaluated. A total of 1,491 patients with positive FOBT results underwent total colonoscopy at the Institute of Gastroenterology, Nippon Medical School, Musashi Kosugi Hospital, from April 2002 through July 2009. Abnormalities were found in 1,312 of the 1,491 patients (88.0%). Ninety-six of the 1,491 patients (6.4%) were found to have early cancer, but 59 patients (4.0%) were found to have advanced cancer. The early cancers were treated with endoscopic mucosal resection or endoscopic submucosal dissection in 81 patients, with laparoscopy-assisted colectomy in 10 patients, and with open surgery in 5 patients. Fifty-one of the 59 patients with advanced colorectal cancer underwent conventional open surgery, and 8 patients underwent laparoscopic surgery. The cancers detected were more likely to be early cancers than advanced cancers. In addition to malignancies, other abnormalities found included inner or external hemorrhoids, diverticula of the colon, ulcerative colitis, ischemic colitis, infectious colitis, and colorectal polyps. Our results show that a high percentage of lesions detected with total colonoscopy following a positive FOBT result are early colorectal cancers and polyps.

Purpose: To retrospectively review patients who underwent transjugular and image-guided percutaneous biopsy and compare the relative risk of ascites, thrombocytopenia, and coagulopathy. Materials and Methods: From August 2001 through February 2006, a total of 238 liver biopsies were performed. The radiologist reviewed all patient referrals for transjugular biopsy. These patients either underwent transjugular biopsy or were reassigned to percutaneous biopsy (crossover group). Patients referred to percutaneous image-guided liver biopsy underwent this same procedure. Biopsies were considered successful if a tissue diagnosis could be made from the samples obtained. Results: A total of 36 transjugular biopsies were performed with 3 totalmore » (8.3%) and 1 major (2.8%) complications. A total of 171 percutaneous biopsies were performed with 10 (5.8%) total and 3 (1.8%) major complications. The crossover group showed a total of 4 (12.9%) complications with 1 (3.2%) major complication. Sample adequacy was 91.9% for transjugular and 99.5% for percutaneous biopsy. Conclusion: Both transjugular and percutaneous liver biopsy techniques are efficacious and safe. Contraindications such as thrombocytopenia, coagulopathy, and ascites are indicators of greater complications but are not necessarily prevented by transjugular biopsy. Percutaneous biopsy more frequently yields a diagnostic specimen than transjugular biopsy.« less

The management of the residual cavity during surgical intervention for giant hydatid liver cysts is often a challenging problem. Herein, is described the case of a 55-year-old female patient who was diagnosed with a giant hydatid cyst occupying almost the entire left lobe of the liver. After partial cystectomy, the residual cavity was managed by combination of suture obliteration with omentoplasty. The patient had an uneventful postoperative course and was discharged eight days later. The clinical presentation, diagnostic work-up and surgical management of the patient are discussed, along with a review of the literature.

Ureteral stenosis due to reactivation of the BK virus (BKV) in a state of immunodeficiency is very rare. More common is the appearance of a hemorrhagic cystitis. This report not only shows bilateral ureteral stenosis after bone marrow transplantation, but also presents severe complications as chronic pelvic pain and impaired kidney function as well as irreparable damage to the whole urinary tract leading to nephroureterectomy, subtrigonal cystectomy and orthotopic ileal neobladder. Finally renal transplantation was required. To our knowledge this is the first case in the literature where such a severe course of BKV associated hemorrhagic cystoureteritis is described.

Carcinosarcoma of the urinary bladder is a uncommon tumor with characteristic histopathologic and immunohistochemical findings; his histogenesis have still not been clear; the prognosis seems to be improved by radical cystectomy and adjuvants therapies. We report a case of 47 years old women suffering from suprapubic pains, dysuria and hematuria of five months duration and had a 10 cm suprapubic mass that was found on physical examination. Radiographically, the tumor invaded the dome of the urinary bladder and causes bilateral hydronephrosis. Microscopically it was an urinary bladder carcinosarcoma. Our objective is to discuss the histogenesis, the anatomoclinical and prognosis of these rare tumors.

Orthotopic neo- bladder in women.

PubMed

Schettini, Manlio

2010-12-01

Radical cystectomy is the most effective treatment madality for high grade urinary bladder carcinoma and orthotopic reconstruction is the better urinary diversion modality also in women. From 2002 to 2007 we performed 14 radical cystectomies followed by orthotopic reconstruction in women aged between 47 and 68 years (mean age 56) affected by urinary bladder carcinoma. Our reconstructive technique requires the preparation of two strips of the recti muscles fascia, the sectioning of the bladder neck and, when the uterus is present, hysteroannessiectomy and cystectomy en block leaving intact the lateral and inferior vaginal walls. The pelvic floor is stabilized by a colposacropexis with a prosthesis and placing an omental flap over the prosthesis. The orthotopic reconstruction is achieved via a neobladder according to the Padovana technique. The ureters are anastomized to the neobladder and splinted with single J stents. The pathological examination demonstrated in all patients the presence of a high grade carcinoma (G3): more specifically 4 patients had a full thickness intramural infiltration (T2), 2 patients had involvment of the perivescical fat (T3) ad 8 patients were in T1 stage. Lymphnodes were negative for tumour (NO). In 8 patients blood transfusions were necessary to treat post surgical anemia. No significant intra-, peri- or post operative complications were noted. The mean follow-up was 45 months: a patient died for diffuse metastatic disease after 11 months. The remaining patients are still alive and report normal lifestyle: 10 with normal micturition and 4 with urinary retention treated with intermittent self-catetherization. Two patients report nocturnal incontinence treated with hourly micturition and one pad. The five patients who had normal preoperative sexual intercourse resumed a normal sexual activity. The possibility to orthotopically recontruct the female urinary bladder has been established long time after the introduction of orthotopic neobladder in males, when became obvious that bladder reconstruction had to be done in conjunction with the reconstruction of the pelvic floor, in order to assure a satisfactory function at the new bladder. To avoid a posterior slippage of the vaginal stump we inserted the vaginal stump into a prolene tube which was then anchored posteriorly to the sacral periostium. We covered the prolene net with a flap of omentum pedicled down from the transverse colon and brought into the pelvis through the right colic space. This solid, stable and well protected support was able to accept the new bladder. We use the Padovana technique to facilitate the anastomosis of the bladder neck to the urethra. In the patients affected by urethral ipermotility we shaped a sub urethral sling using the recti muscles fascia pedicled by the pyramidal muscles. With this modality of reconstruction female pelvic anatomy is preserved as demonstrated by recovery of sexual activity.

Revision of failed total ankle replacement remains a challenge with limited information available to guide treatment options. I undertook a systematic review of electronic databases and other relevant sources to identify material relating to the incidence of revision after primary implantation of the Agility™ Total Ankle Replacement System. In an effort to procure the highest quality studies available, studies were eligible for inclusion only if they involved patients undergoing primary Agility™ Total Ankle Replacement; had evaluated patients at a mean follow-up of 12 months or longer; included details of the revision performed; and included revision etiologies of aseptic loosening, ballooning osteolysis, cystic changes, malalignment, or instability. A total of 14 studies involving 2312 ankles, with a weighted mean follow-up of 22.8 months, were included. Of the 2312 ankles, 224 (9.7%) underwent revision, of which 182 (81.3%) underwent implant component replacement, 34 (15.2%) underwent arthrodesis, and 8 (3.6%) underwent below-knee amputation. No significant effect from the surgeon's learning curve on the incidence of revision or the type of revision surgery performed was identified. However, excluding the inventor increased the incidence of revision twofold, from 6.6% to 12.2%, and skewed the type of revision away from arthrodesis and toward implant component replacement or below-knee amputation. Regardless, the incidence of revision after primary implantation of the Agility™ Total Ankle Replacement System was less than historically reported and amenable to implant component revision more than 80% of the time. However, methodologically sound cohort studies are needed that include the outcomes after revision surgery, specifically focusing on what implant component replacement techniques are effective in enhancing survivorship of these revised implants and the role of custom-stemmed talar and tibial components have in revision of the Agility™ Total Ankle Replacement System. A direct comparison of the incidence of revision between the various contemporary total ankle replacement systems in common use is also warranted.

Historically, stage I rectal cancer was treated with total mesorectal excision. However, there has been growing use of local excision, with and without adjuvant therapy, to treat these early rectal cancers. Little is known about how patients and providers choose among the various treatment approaches. The purpose of this study was to identify patient roles, preferences, and expectations as they relate to treatment decision making for patients with stage I rectal cancer. This is a population-based study. The study included a geographically diverse population and health-system-based cohort. A total of 154 adults with newly diagnosed and surgically treated stage I rectal cancer between 2003 and 2005 were included. We compared patients by surgical treatment groups, including total mesorectal excision and local excision. Clinical, sociodemographic, and health-system factors were assessed for association with patient decision-making preferences and expectations. A total of 80% of patients who underwent total mesorectal excision versus 63% of patients who underwent local excision expected that surgery would be curative (p = 0.04). The total mesorectal excision group was less likely to report that radiation would cure their cancer compared with the local excision group (27% vs 63%; p = 0.004). When asked about their preferred role in decision making, 28% of patients who underwent total mesorectal excision preferred patient-controlled decision making compared with 48% of patients who underwent local excision (p = 0.046). However, with regard to the treatment actually received, 38% of the total mesorectal excision group reported making their own surgical decision compared with 25% of the local excision group (p = 0.18). The study was limited by its sample size. The preferred decision-making role for patients did not match the actual decision-making process. Future efforts should focus on bridging the gap between the decision-making process and patient preferences regarding various treatment approaches. This will be particularly important as newer innovative procedures play a more prominent role in the rectal cancer treatment paradigm.

It is believed that patients who undergo thyroidectomy for Graves' disease are more likely to experience postoperative hypocalcemia than patients undergoing total thyroidectomy for other indications. However, no study has directly compared these two groups of patients. The aim of this study was to determine whether there was an increased incidence or severity of postoperative hypocalcemia in patients who underwent thyroidectomy for Graves' disease. An institutional review board-approved database was created of all patients who underwent thyroidectomy from 1998 to 2009 at the Johns Hopkins Hospital. There were a total of 68 patients with Graves' disease who underwent surgery. Fifty-five patients who underwent total thyroidectomy were randomly selected and served as control subjects. An analysis was conducted that examined potential covariates for postoperative hypocalcemia, including age, gender, ethnicity, preoperative alkaline phosphatase level, size of goiter, whether parathyroid tissue or glands were present in the specimen, and the reason the patient underwent surgery. Specific outcomes examined were calcium levels on postoperative day 1, whether or not patients experienced symptoms of hypocalcemia, whether or not Rocaltrol was required, the number of calcium tablets prescribed upon discharge, whether or not postoperative tetany occurred, and calcium levels 1 month after discharge. Each outcome was analyzed using a logistic regression. Graves' disease patients had a significantly (p-value < 0.001) higher odds of greater number of calcium tablets prescribed upon discharge. Further, 6 of 68 patients with Graves' disease and no patient in the control group were readmitted with tetany (p = 0.033). There was a trend, though not significant, toward patients with Graves' disease having a higher prevalence of hypocalcemia the day after thyroidectomy and 1 month later. Patients with Graves' disease are more likely to require increased dosages of calcium as well as experience tetany postoperatively than patients undergoing total thyroidectomy for other indications. This suggests that patients operated upon for Graves' disease warrant close followup as both inpatients and outpatients for signs and symptoms of hypocalcemia.

Robotic-assisted surgery is gaining popularity in general surgery. Our objective was to evaluate and compare operative outcomes and total costs for robotic cholecystectomy (RC) and laparoscopic cholecystectomy (LC). A retrospective review was performed for all patients who underwent single-procedure RC and LC from January 2011 to July 2015 by a single surgeon at a large academic medical center. Demographics, diagnosis, perioperative variables, postoperative complications, 30-day readmissions, and operative and hospital costs were collected and analyzed between those patient groups. A total of 237 patients underwent RC or LC, and comprised the study population. Ninety-seven patients (40.9 %) underwent LC, and 140 patients (50.1 %) underwent RC. Patients who underwent RC had a higher body mass index (p = 0.03), lower rates of coronary artery disease (p < 0.01), and higher rates of chronic cholecystitis (p < 0.01). There were lower rates of intraoperative cholangiography (p < 0.01) and conversion to an open procedure (p < 0.01), however longer operative times (p < 0.01) for patients in the RC group. There were no bile duct injuries in either group, no difference in bile leak rates (p = 0.65), or need for reoperation (p = 1.000). Cost analysis of outpatient-only procedures, excluding cases with conversion to open or use of intraoperative cholangiography, demonstrated higher total charges (p < 0.01) and cost (p < 0.01) and lower revenue (p < 0.01) for RC compared to LC, with no difference in total payments (p = 0.34). Robotic cholecystectomy appears to be safe although costlier in comparison with laparoscopic cholecystectomy. Further studies are needed to understand the long-term implications of robotic technology, the cost to the health care system, and its role in minimally invasive surgery.

To assess the feasibility of radical perineal cystoprostatectomy using the latest generation purpose-built single-port robotic surgical system. In two male cadavers the da Vinci ® SP1098 Surgical System (Intuitive Surgical, Sunnyvale, CA, USA) was used to perform radical perineal cystoprostatectomy and bilateral extended pelvic lymph node dissection (ePLND). New features in this model include enhanced high-definition three-dimensional optics, improved instrument manoeuvrability, and a real-time instrument tracking and guidance system. The surgery was accomplished through a 3-cm perineal incision via a novel robotic single-port system, which accommodates three double-jointed articulating robotic instruments, an articulating camera, and an accessory laparoscopic instrument. The primary outcomes were technical feasibility, intraoperative complications, and total robotic operative time. The cases were completed successfully without conversion. There were no accidental punctures or lacerations. The robotic operative times were 197 and 202 min. In this preclinical model, robotic radical perineal cystoprostatectomy and ePLND was feasible using the SP1098 robotic platform. Further investigation is needed to assess the feasibility of urinary diversion using this novel approach and new technology. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

Robotic applications have achieved safe and precise thyroidectomy with notable cosmetic and functional benefits. This study was designed to document the influence of body habitus on robotic thyroidectomy in papillary thyroid carcinoma (PTC) patients. From July 2009 to February 2010, 352 patients underwent robotic thyroidectomy using a gasless, transaxillary single-incision approach at Yonsei University Health System. Body habitus was described using body mass index category (normal weight, overweight, obese), neck length, shoulder width, and shoulder width to neck length ratios. The impact of body habitus on surgical outcomes was analyzed with respect to operation time, number of retrieved central nodes, bleeding amount, and postoperative complications. Of the 352 patients, 217 underwent less than total thyroidectomy and 135 underwent total thyroidectomy. Operative variables (i.e. operation times, bleeding amounts, and numbers of retrieved central nodes) showed no significant differences between three BMI groups for less than total thyroidectomy. However, total operation and working space times were longer for obese patients during total thyroidectomy. In particular, shoulder width was positively correlated with total operation time, working space time, console time, and number of retrieved central nodes. On the other hand, postoperative complications were not significantly different in the three BMI groups and showed no significant correlation with the other indices of body habitus. Standardized robotic thyroidectomy can be performed safely and feasibly in patients with a large body habitus despite longer operation times.

We retrospectively evaluated early and intermediate outcomes of aortic arch surgery in patients with type A acute aortic dissection (AAD), investigating the effect of arch surgery extension on postoperative results. From January 2006 through July 2013, 201 patients with type A AAD underwent urgent corrective surgery at our institution. Of the 92 patients chosen for this study, 59 underwent hemiarch replacement (hemiarch group), and 33 underwent total arch replacement (total arch group) in conjunction with ascending aorta replacement. The operative mortality rate was 22%. Total arch replacement was associated with a 33% risk of operative death, versus 15% for hemiarch ( P =0.044). Multivariable analysis found these independent predictors of operative death: age (odds ratio [OR]=1.13/yr; 95% confidence interval [CI], 1.04-1.23; P =0.002), body mass index >30 kg/m 2 (OR=9.9; 95% CI, 1.28-19; P =0.028), postoperative low cardiac output (OR=10.6; 95% CI, 1.18-25; P =0.035), and total arch replacement (OR=8.8; 95% CI, 1.39-15; P =0.021) The mean overall 5-year survival rate was 59.3% ± 5.5%, and mean 5-year freedom from distal reintervention was 95.4% ± 3.2% ( P =NS). In type A AAD, aortic arch surgery is still associated with high operative mortality rates; hemiarch replacement can be performed more safely than total arch replacement. Rates of distal aortic reoperation were not different between the 2 surgical strategies.

Uterine necrosis is one of the rarest complications following pelvic arterial embolization for postpartum hemorrhage (PPH). With the increasing incidence of cesarean section and abnormal placental localization (placenta previa) or placental invasion (placenta accreta/increta/percreta), more and more cases of uterine necrosis after embolization are being diagnosed and reported. Pelvic computed tomography or magnetic resonance imaging provides high diagnostic accuracy, and surgical management includes hysterectomy. We performed a Medline database query following the first description of uterine necrosis after pelvic embolization (between January 1985 and January 2013). Medical subheading search words were the following: "uterine necrosis"; "embolization"; "postpartum hemorrhage". Seventeen citations reporting at least one case of uterine necrosis after pelvic embolization for PPH were included, with a total of 19 cases. This literature review discusses the etiopathogenesis, clinical and therapeutic aspects of uterine necrosis following pelvic arterial embolization, and guidelines are detailed. The mean time interval between pelvic embolization and diagnosis of uterine necrosis was 21 days (range 9-730). The main symptoms of uterine necrosis were fever, abdominal pain, menorrhagia and leukorrhea. Surgical management included total hysterectomy (n=15, 78%) or subtotal hysterectomy (n=2, 10%) and partial cystectomy with excision of the necrotic portion in three cases of associated bladder necrosis (15%). Uterine necrosis was partial in four cases (21%). Regarding the pathophysiology, four factors may be involved in uterine necrosis: the size and nature of the embolizing agent, the presence of the anastomotic vascular system and the embolization technique itself with the use of free flow embolization.

Standardized methods of reporting complications after radical cystectomy (RC) and urinary diversions (UD) are necessary to evaluate the morbidity associated with this operation to evaluate the modified Clavien classification system (CCS) in grading perioperative complications of RC and UD in a real life cohort of patients with bladder cancer. A consecutive series of patients treated with RC and UD from April 2011 to March 2012 at 19 centers in Italy was evaluated. Complications were recorded according to the modified CCS. Results were presented as complication rates per grade. Univariate and binary logistic regression analysis were used for statistical analysis. 467 patients were enrolled. Median age was 70 years (range 35-89). UD consisted in orthotopic neobladder in 112 patients, ileal conduit in 217 patients and cutaneous ureterostomy in 138 patients. 415 complications were observed in 302 patients and were classified as Clavien type I (109 patients) or II (220 patients); Clavien type IIIa (45 patients), IIIb (22 patients); IV (11 patients) and V (8 patients). Patients with cutaneous ureterostomy presented a lower rate (8%) of CCS type ≥IIIa (p = 0.03). A longer operative time was an independent risk factor of CCS ≥III (OR: 1.005; CI: 1.002-1.007 per minute; p = 0.0001). In our study, RC is associated with a significant morbidity (65%) and a reduced mortality (1.7%) when compared to previous experiences. The modified CCS represents an easily applicable tool to classify the complications of RC and UD in a more objective and detailed way. Copyright © 2013 Elsevier Ltd. All rights reserved.

To study safety, feasibility, and biologic activity of adenovirus-mediated p53 gene transfer in patients with bladder cancer. Twelve patients with histologically confirmed bladder cancer scheduled for cystectomy were treated on day 1 with a single intratumoral injection of SCH 58500 (rAd/p53) at cystoscopy at one dose level (7.5 x 10(11) particles) or a single intravesical instillation of SCH 58500 with a transduction-enhancing agent (Big CHAP) at three dose levels (7.5 x 10(11) to 7.5 x 10(13) particles). Cystectomies were performed in 11 patients on day 3, and transgene expression, vector distribution, and biologic markers of transgene activity were assessed by molecular and immunohistochemical methods in tumors and normal bladder samples. Specific transgene expression was detected in tissues from seven of eight assessable patients treated with intravesical instillation of SCH 58500 but in none of three assessable patients treated with intratumoral injection of SCH 58500. Induction of RNA and protein expression of the p53 target gene p21/WAF1 was demonstrated in samples from patients treated with SCH 58500 instillation at higher dose levels. Distribution studies after intravesical instillation of SCH 58500 revealed both high transduction efficacy and vector penetration throughout the whole urothelium and into submucosal tumor cells. No dose-limiting toxicity was observed, and side effects were local and of transient nature. Intravesical instillation of SCH 58500 combined with a transduction-enhancing agent is safe, feasible, and biologically active in patients with bladder cancer. Studies to evaluate the clinical efficacy of this treatment in patients with localized high-risk bladder cancer are warranted.

Little is known about the clonal architecture of human urothelium. It is likely that urothelial stem cells reside within the basal epithelial layer, yet lineage tracing from a single stem cell as a means to show the presence of a urothelial stem cell has never been performed. Here, we identify clonally related cell areas within human bladder mucosa in order to visualize epithelial fields maintained by a single founder/stem cell. Sixteen frozen cystectomy specimens were serially sectioned. Patches of cells deficient for the mitochondrially encoded enzyme cytochrome c oxidase (CCO) were identified using dual-colour enzyme histochemistry. To show that these patches represent clonal proliferations, small CCO-proficient and -deficient areas were individually laser-capture microdissected and the entire mitochondrial genome (mtDNA) in each area was PCR amplified and sequenced to identify mtDNA mutations. Immunohistochemistry was performed for the different cell layers of the urothelium and adjacent mesenchyme. CCO-deficient patches could be observed in normal urothelium of all cystectomy specimens. The two-dimensional length of these negative patches varied from 2-3 cells (about 30 µm) to 4.7 mm. Each cell area within a CCO-deficient patch contained an identical somatic mtDNA mutation, indicating that the patch was a clonal unit. Patches contained all the mature cell differentiation stages present in the urothelium, suggesting the presence of a stem cell. Our results demonstrate that the normal mucosa of human bladder contains stem cell-derived clonal units that actively replenish the urothelium during ageing. The size of the clonal unit attributable to each stem cell was broadly distributed, suggesting replacement of one stem cell clone by another.

Single incision laparoscopic surgery (SILS) represents the latest advancement in minimally invasive surgery, combining the benefits of conventional laparoscopic surgery, such as less pain and faster recovery, with improved cosmesis. Although the successful use of this technique is well reported in general surgery and urology, there is a lack of studies on SILS in gynaecology. To evaluate the feasibility, safety, cosmesis and outcome of SILS in gynaecology. A prospective case series analysis of 105 women scheduled to undergo surgery by SILS from August 2010 to November 2011. Intra-operative data such as operative time, estimated blood loss, complications, additional ports and hospital stay were collected. Post-operative pain and cosmetic outcomes (scar size) were also recorded. Out of 105 women, SILS was performed for 84 (60 excisions of endometriosis, 13 divisions of adhesions, five hysterectomies, two mesh sacrohysteropexies and four ovarian cystectomies). SILS was not undertaken for 21 women because of a number of factors, including the lack of required equipment (eg bariatric scope, SILS port, roticulating instruments and diathermy leads). Four women required insertion of additional ports because of surgical difficulties. One intra-operative (uterine perforation) and seven post-operative complications (six wound infections and one vault haematoma) occurred. Mean operation times were as follows: mesh sacrohysteropexy - 60 min, excision of endometriosis - 55 min, hysterectomy - 150 min, laparoscopic division of adhesions - 62 min and ovarian cystectomy - 40 min. Our experience shows that SILS is a feasible and safe technique for the surgical management of various gynaecological conditions. Satisfaction is high because of improved cosmesis and reduced analgesic requirements post-operatively. © 2012 The Authors ANZJOG © 2012 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

To investigate the characteristics and outcomes of patients with muscle-invasive bladder cancer (MIBC) treated with transurethral resection (TUR) plus chemotherapy alone in a large observational cohort reflecting the continuum of practice settings in the United States. Within the National Cancer Database (2004-2015), we identified 1,538 patients treated with TUR plus multi-agent chemotherapy as definitive treatment for cT2-T4aN0M0 urothelial carcinoma of the bladder. For comparison purposes, we included 17,866 patients treated with radical cystectomy ± perioperative chemotherapy. Baseline characteristics were compared between the 2 groups using multivariable logistic regression. Treatment outcomes were assessed using Kaplan-Meier analysis and Cox regression model. In multivariate analysis, several variables, including patients' demography (older age, African-American race, prior malignancy, lack of insurance), tumor characteristics (higher cT stage) and facility types (non-academic facilities, lower volume of radical cystectomy) were associated with a higher probability of receiving TUR plus chemotherapy for MIBC, compared to the standard of care. The 2-year and 5-year survival rates for all patients treated with TUR plus chemotherapy were 49.0% and 32.9% and limited to patients with cT2 disease were 52.6% and 36.2%, respectively. This large population-level cohort of unselected patients shows that long-term survival can be achieved in a subset of patients treated with TUR plus chemotherapy alone for MIBC. However, the best candidates for this approach remain to be defined. Ongoing clinical trials are now being launched to evaluate the ability of biomarkers to accurately select patients who could be treated with this bladder-sparing strategy.

Early postoperative acute kidney injury (AKI) is associated with increased morbidity and mortality following major surgery. Only few reports exist on postoperative AKI and specifically its risk factors after radical cystectomy (RC) and urinary diversion (UD). We aimed to identify risk factors for AKI in patients undergoing RC and UD. In an observational single-center cohort study, 912 consecutive bladder cancer patients undergoing RC and UD from 2000 to 2016 were evaluated for risk factors for AKI. Multiple logistic regression analysis was performed to model the association between variables and AKI. Early postoperative AKI occurred in 100/912 patients (11%). An increased risk was seen in patients with surgery lasting>400minutes, male and obese patients (>25kg/m²). Independent predictors were duration of surgery (P = 0.020), intraoperative blood loss (P = 0.049), preoperative serum creatinine values (P = 0.004), intraoperative administration of crystalloids (P = 0.032), body mass index (P = 0.031), and fluid balance (P = 0.006). Patients with AKI had a longer hospitalization time (18d vs 17d, P = 0.040). Limitations include the potential bias due to the design as a case series with prospectively collected data with some missing values. An increased risk for AKI was seen in patients with an operative time>400 minutes. Hence, in this group of patients the role of postoperative fluid management for preserving renal function should be considered. Further independent predictors of postoperative AKI were male sex, obesity, intraoperative blood loss, and a low preoperative plasma creatinine. So specially in male and obese patients, optimized perioperative nephroprotective strategies are of importance. Copyright © 2018 Elsevier Inc. All rights reserved.

To evaluate the effects of thyroid cystectomy for primary hyperparathyroidism on immune function. Ninety-two patients with parathyroid cysts complicated with primary hyperparathyroidism were randomly divided into a treatment group and a control group (n=46). The treatment group received endoscopic thyroidectomy through the anterior chest wall via the areolar approach, and the control group was treated with conventional open thyroidectomy. The two groups had similar immune function indices as well as thyroid hormone, serum calcium and phosphorus levels before surgery (P>0.05). After surgery, FT3 and FT4 levels significantly increased in both groups, whereas that of TSH significantly decreased (P<0.05). The levels of the two groups differed significantly on the postoperative 5th day (P<0.05). NK%, CD3+%, CD4+% and CD8+%, which significantly fluctuated on the postoperative 1st day in both groups (P<0.05), were basically recovered on the postoperative 5th day in the treatment group that had significantly different outcomes from those of the control group (P<0.05). On the postoperative 1st and 5th days, the treatment group had significantly lower serum calcium level and significantly higher serum phosphorus level than those of the control group (P<0.05). The surgeries were successfully performed for all patients. During three months of follow-up, the treatment group was significantly less prone to complications such as surgical site infection, recurrent laryngeal nerve injury, parathyroid crisis and hoarseness than the control group (P<0.05). For treatment of primary hyperparathyroidism, endoscopic thyroidectomy through the anterior chest wall via the areolar approach decreased the incidence rate of complications, as well as promoted the recovery of serum calcium and phosphorous levels, probably by only mildly affecting immune function and thyroid hormone levels.

The aim of this study was to validate the value of preoperative patient characteristics in prognosticating survival after radical cystectomy (RC) to guide treatment decisions regarding neoadjuvant systemic treatment. We evaluated a single cohort of 449 consecutive patients treated with RC for bladder cancer. Patients treated with neoadjuvant therapy were excluded from the study cohort (n = 24). Patients were stratified based on preoperative characteristics into 2 risk groups. The high-risk group included patients harboring clinically non-organ-confined disease (≥ cT3), hydroureteronephrosis, lymphovascular invasion, or variant histology (micropapillary, neuroendocrine, sarcomatoid, or plasmacytoid variants on transurethral resection). The low-risk group included patients with cT2 disease without any of the aforementioned features. Survival expectancies after surgery were evaluated using competing risk and Kaplan-Meier analyses. We identified 153 (44.6%) low-risk and 190 (55.4%) high-risk patients. The majority of high-risk patients had only 1 high-risk feature (n = 111; 58.4%); the most common high-risk feature was preoperative hydroureteronephrosis (n = 107; 56.3%). The majority of low-risk patients were upstaged at time of RC (n = 118; 70.6%), whereas a pathologic downstage occurred only in 27 high-risk patients (14.2%). Cancer-specific mortality-free rates at 5 years after RC were 77.4% versus 64.4% for low-risk versus high-risk patients, respectively. We confirm that preoperative risk features can stratify patients with muscle-invasive bladder cancer into differential risk groups regarding survival. Decision-making regarding neoadjuvant systemic therapy administration is likely to be improved by integrating clinical stage, lymphovascular invasion, variant histology, and hydroureteronephrosis.

To assess health-related quality of life (HRQoL) parameters in patients who received radical cystectomy (RC) with ileal orthotopic neobladder (IONB) reconstruction and to identify clinic-pathologic predictors of HRQoL. From January 2010 to December 2013, a multicenter, retrospective on 174 RC-IONB patients was carried out. All patients completed the following questionnaires: the European Organization for Research and Treatment of Cancer (EORTC) generic (QLQ-C30) and bladder cancer-specific instruments (QLQ-BLM30) and the IONB-Patient Reported Outcome (IONB-PRO). Univariate and multivariate analyses were computed to identify clinic-pathologic predictors of HRQoL. Median age was 66 years (range, 31-83), and 91.4% of patients were men. Median follow-up period was 37 months (range, 3-247). The EORTC QLQ-C30 revealed that age >65 years, absence of urinary incontinence, and absence of peripheral vascular disease were independent predictors of deteriorated body image. A follow-up > 36 months and the presence of urinary incontinence were independent predictors of worsened urinary symptoms, whereas the absence of urinary incontinence was an independent predictor of a worsened body image according to EORTC QLQ-BLM30 results. A follow-up >36 months and the absence of urinary incontinence were independent predictors of better functioning in terms of relational life, emotional life, and fatigue as revealed by the IONB-PRO. Age, presence of urinary incontinence, length of follow-up, and comorbidity status may influence postoperative HRQoL and should all be taken into account when counseling RC-IONB patients.

Bile leak is the main cause of morbidity and mortality after surgery for hydatid liver cysts. Aim was to assess the role of prophylactic endoscopic sphincterotomy (ES) in reducing postoperative bile leak in patients undergoing partial cystectomy. Fifty-four patients with hepatic hydatid cyst met inclusion criteria, 27 were excluded or declined to participate. Twenty-six women and 28 men (mean age 44.6 ± 10.1, range: 22-61 years) were randomly assigned to either group I with ES (n = 27) or group II without ES (n = 27). Demographics and clinical, laboratory, and radiological characteristics of cysts were not statistically different between two groups. Group I had a significant decrease in bile leak rate compared with group II (11.1% versus 40.7%, P = .013), with significantly shorter duration of hospital stay (P < .0001). Biliary fistula in group I had significantly lower daily output (100 mL/day versus 350 mL/day) with gradual reduction till stoppage of leak in 3-4 days without intervention. Biliary fistula in group II had a significantly higher need for biliary intervention through postoperative endoscopic retrograde cholangiopancreatography with ES compared with biliary fistula in group I ( FE P = .002), with significantly longer mean time of fistula closure (P = .011) and longer time to drain removal (P < .0001). Nonbiliary complications were comparable between two groups. Prophylactic ES provides significant reduction in postoperative bile leak rate with shorter hospital stay after partial cystectomy of hydatid cyst. Biliary fistula in patients with ES has significantly lower daily output with shorter time of drain removal and shorter time to closure than patients without ES.

We had previously demonstrated changes in defecation after radical cystectomy (RC). Reports addressing long-term bowel disorders following RC are rare. This cross-sectional study evaluates long-term bowel issues in a large cohort. A questionnaire assessing changes in bowel function (diarrhea, constipation, urge to defecate, sensation of incomplete defecation, and flatulence) and its effect on quality of life was developed based on the gastrointestinal quality of life index and distributed in collaboration with the German bladder cancer support group. There were 431 evaluable questionnaires. For the analyses, we focused on patients that had the RC>1 year ago (n = 324). Current bowel problems were reported by 42.6% of patients. The most frequent bowel problems were flatulence (48.8%), diarrhea (29.6%), and sensation of incomplete defecation (22.5%). In cases of bowel problems, 39.7% and 59.8% of the patients indicated life restriction and dissatisfaction, respectively. Prevalence of diarrhea and flatulence were significantly higher>12 (vs. ≤12) months following RC. Both symptoms significantly correlated with younger age at RC, life restriction, lower quality of life, lower health state, and lower energy level. Additionally, diarrhea significantly correlated with pouches as urinary diversion (vs. ileal conduit or ureterocutaneostomy) and higher dissatisfaction level. To our knowledge this is the largest cohort evaluating long-term bowel symptoms after RC. Diarrhea is a prominent symptom after RC with a high impact on daily life that leads to dissatisfaction. A better understanding of long-term bowel symptoms could be translated into optimized surgical procedures, postoperative medication/nutrition, and patient education. Copyright © 2018 Elsevier Inc.

Purpose Postoperative ileus (POI) is common following bowel resection for radical cystectomy with ileal conduit (RCIC). We investigated perioperative factors associated with prolonged POI following RCIC, with specific focus on opioid-based analgesic dosage. Materials and Methods From March 2007 to January 2013, 78 open RCICs and 26 robot-assisted RCICs performed for bladder carcinoma were identified with adjustment for age, gender, American Society of Anesthesiologists grade, and body mass index (BMI). Perioperative records including operative time, intraoperative fluid excess, estimated blood loss, lymph node yield, and opioid analgesic dose were obtained to assess their associations with time to passage of flatus, tolerable oral diet, and length of hospital stay (LOS). Prior to general anaesthesia, patients received epidural patient-controlled analgesia (PCA) consisted of fentanyl with its dose adjusted for BMI. Postoperatively, single intravenous injections of tramadol were applied according to patient desire. Results Multivariate analyses revealed cumulative dosages of both PCA fentanyl and tramadol injections as independent predictors of POI. According to surgical modality, linear regression analyses revealed cumulative dosages of PCA fentanyl and tramadol injections to be positively associated with time to first passage of flatus, tolerable diet, and LOS in the open RCIC group. In the robot-assisted RCIC group, only tramadol dose was associated with time to flatus and tolerable diet. Compared to open RCIC, robot-assisted RCIC yielded shorter days to diet and LOS; however, it failed to shorten days to first flatus. Conclusion Reducing opioid-based analgesics shortens the duration of POI. The utilization of the robotic system may confer additional benefit. PMID:25048497

To compare robot-assisted laparoscopy (RL) and conventional laparoscopy (CL) in surgery for bladder endometriosis. A retrospective study was conducted between January 2007 and December 2013, including patients with bladder endometriosis receiving at least a partial cystectomy by RL or CL. The primary endpoint was the presence of a radiological recurrence at bladder level. We included 15 patients in the RL group and 22 in the CL group. The median age was 29 years±7 years. The symptoms were similar in the 2 groups. Pre-surgical mapping of the lesions was carried out with MRI. Sixty percent of patients in the RL group vs 91% in the CL group had other associated endometriosis lesions, P=0.04. The median size of the bladder lesion was 30±8mm in the RL group vs 23±7mm in the CL group, P=0.03. The median operative time was 210 vs 225min, P=0.8. We did not find any significant difference in intraoperative and early and late postoperative complications between the 2 groups. The median length of stay was 5 days vs 6 days. The proportion of relapse was 20 vs 23%, P>0.05. Clinical improvement was similar between the groups, i.e. 93 vs 86%, P=0.6 and the pregnancy rate was 93 vs 86%, P=0.6. Robot-assisted laparoscopy in the surgical treatment of bladder endometriosis as compared to traditional laparoscopy does not seem to have an adverse effect neither on the risk of recurrence nor on the occurrence of intra- and postoperative complications.

Pelvic exenteration (PE) for locally advanced pelvic malignancy requires a multi-disciplinary approach and is associated with significant morbidity. Urinary reconstruction forms a major component of this procedure. The aim of the study is to review the urological outcomes following PE in a newly established pelvic oncology unit, to compare with those following radical cystectomy (RC) for bladder cancer. Patients were identified from prospectively maintained PE and bladder cancer databases, inclusive of all cases performed between January 2012 and December 2016. Those without urinary reconstructions and follow-up durations of less than 3 months were excluded. The outcomes of PE and RC cases were compared, stratifying surgical complications using the Clavien-Dindo classification. Statistical significance was defined as P < 0.05. There were 22 PE cases and 27 RC cases. The median age at surgery was 56 and 65 years, with a median follow-up of 11.7 and 19.8 months, in the PE and RC groups, respectively. Urinary reconstructions comprised n = 20 (91%) conduit diversions and n = 2 (9%) ureteral reimplantations in the PE group, and n = 5 (19%) orthotopic bladder substitutes and n = 22 (81%) ileal conduits in the RC group. The 30-day urological complication rate was 23% in the PE group (n = 4 Clavien-Dindo Grade 1-2, and n = 1 Grade 3) versus 11% in the RC group (n = 1 Grade 1-2, and n = 2 Grade 3), P = 0.801. There were no Grade 4-5 complications in this series. The urological outcomes following PE in complex pelvic oncology are reasonable and not inferior to those after primary RC alone. © 2018 Royal Australasian College of Surgeons.

To prospectively compare the use of external ureteric stents with internal JJ stenting of the uretero-ileal anastomosis in patients undergoing laparoscopic radical cystectomy (LRC) with a Y-shaped ileal orthotopic neobladder (ON). The study included 69 patients undergoing LRC with ON. Patients were grouped according to the type of uretero-ileal stents used. An external ureteric stent was used in Group A (33 patients) and a JJ stent was used in Group B (36). We prospectively compared the duration of hospital stay, the incidence of short- and intermediate-term complications in the two study groups. The mean (SD) follow-up periods were 29.18 (3.94) and 28.19 (3.37) months for patients in Groups A and B, respectively. Perioperative patient characteristics were comparable in the two study groups. The use of JJ stenting was associated with a shorter hospital stay compared with external stenting, at a mean (SD) of 14.63 (3.74) and 6.8 (3.03) days in Groups A and B, respectively (P < 0.001). The incidence of urinary leakage was comparable in the two study groups, at 6.1% in Group A vs 8.3% in Group B (P = 1.0). Strictures of the uretero-ileal anastomosis occurred in two patients (6%) in Group A and confirmed by intravenous urography. All strictures were treated with antegrade JJ fixation. JJ stents could be used as an effective alternative to external ureteric stents to support the uretero-ileal anastomosis. JJ stenting is associated with a shorter hospital stay and similar complication rates compared with external stenting in patients undergoing LRC with ON.

Precocious pseudopuberty due to an autonomous ovarian follicular cyst: case report with a review of literatures

PubMed Central

2013-01-01

Background Small follicular cysts are commonly found in the ovaries of prepubertal girls, and in most cases, they are of no clinical importance. These cysts are usually self-limiting and resolve spontaneously. However, occasionally, these cysts may enlarge and continue to produce estrogen, resulting in signs of sexual precocity. Here, we report a case of precocious pseudopuberty associated with an autonomous ovarian follicular cyst. Case presentation A 5.9-year-old girl initially presented to a local clinic with vaginal bleeding and a large unilateral ovarian cyst. At 6 months after the initial acute episode, the patient visited our hospital as the ovarian cyst had persisted and increased in size. Endocrinological examination showed elevated estrogen levels and suppressed gonadotropin levels on GnRH stimulation test. Also, no skin pigmentation or bone anomaly was noted. Based on these observations, laparoscopic cystectomy was performed, and histologic analysis confirmed the diagnosis of a follicular cyst. After the laparoscopic cystectomy, the patient’s hormone levels returned to normal and no ovarian cyst was detected by ultrasound. Conclusions As autonomous ovarian cysts are usually self-limiting disorder, no treatment is necessary. Therefore, surgical management should be deferred as long as possible to avoid the risk of repeat surgery, as pseudoprecocious puberty due to autonomous ovarian cysts can resolve spontaneoulsy and frequently recurs. Precocious pseudopuberty with an ovarian cyst may be due to granulosa cell tumor or may be one symptom of the McCune-Albright Syndrome (MAS). A careful longer-term follow up of patients with autonomous ovarian cysts and/or molecular studies may be necessary in such cases. PMID:23937919

To identify preoperative factors correlated with postoperative early renal function in patients who had undergone radical cystectomy (RC) and intestinal urinary diversion. We retrospectively identified 201 consecutive bladder cancer patients without distant metastasis who had undergone RC at our institution between 2003 and 2012. The estimated glomerular filtration rate (eGFR) was calculated using the modified Chronic Kidney Disease Epidemiology equation before RC and 3 months following RC. Univariate and stepwise multiple linear regression analyses were applied to estimate postoperative renal function and to identify significant preoperative predictors of postoperative renal function. Patients who had undergone intestinal urinary diversion and were available for the collection of follow-up data (n = 164) were eligible for the present study. Median preoperative and postoperative eGFRs were 69.7 (interquartile range [IQR] 56.3-78.0) and 70.7 (IQR 57.3-78.1), respectively. In univariate analyses, age, preoperative proteinuria, thickness of abdominal subcutaneous fat tissue (TSF), preoperative serum creatinine level, preoperative eGFR, and urinary diversion type were significantly associated with postoperative eGFR. In a stepwise multiple linear regression analysis, preoperative eGFR, age, and TSF were significant factors for predicting postoperative eGFR (p < 0.001, p = 0.02, and p = 0.046, respectively). The estimated postoperative eGFRs correlated well with the actual postoperative eGFRs (r = 0.65, p < 0.001). Preoperative eGFR, age, and TSF were independent preoperative factors for determining postoperative renal function in patients who had undergone RC and intestinal urinary diversion. These results may be used for patient counseling before surgery, including the planning of perioperative chemotherapy administration.

Multidetector coronary computed tomographic angiography (CCTA) demonstrates high accuracy for the detection and exclusion of coronary artery disease (CAD) and predicts adverse prognosis. To date, opportunity costs relating the clinical and economic outcomes of CCTA compared with other methods of diagnosing CAD, such as myocardial perfusion single-photon emission computed tomography (SPECT), remain unknown. An observational, multicenter, patient-level analysis of patients without known CAD who underwent CCTA or SPECT was performed. Patients who underwent CCTA (n = 1,938) were matched to those who underwent SPECT (n = 7,752) on 8 demographic and clinical characteristics and 2 summary measures of cardiac medications and co-morbidities and were evaluated for 9-month expenditures and clinical outcomes. Adjusted total health care and CAD expenditures were 27% (p <0.001) and 33% (p <0.001) lower, respectively, for patients who underwent CCTA compared with those who underwent SPECT, by an average of $467 (95% confidence interval $99 to $984) for CAD expenditures per patient. Despite lower total health care expenditures for CCTA, no differences were observed for rates of adverse cardiovascular events, including CAD hospitalizations (4.2% vs 4.1%, p = NS), CAD outpatient visits (17.4% vs 13.3%, p = NS), myocardial infarction (0.4% vs 0.6%, p = NS), and new-onset angina (3.0% vs 3.5%, p = NS). Patients without known CAD who underwent CCTA, compared with matched patients who underwent SPECT, incurred lower overall health care and CAD expenditures while experiencing similarly low rates of CAD hospitalization, outpatient visits, myocardial infarction, and angina. In conclusion, these data suggest that CCTA may be a cost-efficient alternative to SPECT for the initial coronary evaluation of patients without known CAD.

Urethroplasty is often successful for the treatment of male urethral stricture disease, but limited data exists on recurrence management. Our goal was to evaluate direct visual internal urethrotomy (DVIU) as a treatment option for isolated, recurrent strictures after urethroplasty. We retrospectively identified male patients who underwent urethroplasty from 1999 to 2013 and developed an isolated, recurrent stricture at the urethroplasty site treated with DVIU. Success was defined as lack of symptomatology and no subsequent intervention. Comparative analysis identified characteristics and stricture properties associated with success. A total of 436 urethroplasties were performed in 401 patients at our institution between 1999 and 2013. Stricture recurrence was noted in 64 (16%) patients. Of these, 47 (73%) underwent a DVIU. A total of 37 patients met inclusion criteria and underwent 50 DVIU procedures at the urethroplasty site. A single DVIU was successful in 13 of 37 patients (35%). A total of 4 of 6 patients required a second DVIU (67%). Overall, 17 of 43 (40%) of the total DVIUs were successful after urethroplasty. Success did not differ by age, stricture length or location, surgical technique, radiation history, prior urethroplasty or DVIU, time to failure, or etiology. Post-urethroplasty DVIU for isolated, recurrent strictures may be offered as a minimally invasive treatment option. Approximately 40% of patients were spared further intervention.

We retrospectively evaluated a series of patients who underwent minimally invasive video-assisted thyroidectomy (MIVAT) to define its advantages or disadvantages. Between May 2005 and March 2008, 68 patients underwent MIVAT. Sixty-nine patients who underwent conventional thyroidectomy (CT) during the period before the introduction of the MIVAT technique in our department-chosen with the same inclusion criteria used for MIVAT-served as matched controls. The eligibility criteria for both groups was thyroid nodules < or = 35 mm, thyroid volume < 25 ml, no thyroiditis, and no previous surgery. Forty-five MIVAT and 43 CT patients underwent hemithyroidectomy. Twenty-three MIVAT and 26 CT patients underwent total thyroidectomy. No differences were found in terms of complications, operative time, and radicality of the procedure. Patients who underwent MIVAT experienced significantly less pain, better cosmetic results, and shorter hospital stay than patients who underwent conventional surgery The MIVAT technique, in selected patients, seems to be a valid option for thyroidectomy and even preferable to conventional surgery because of its significant advantages, especially in terms of cosmetic results, postoperative pain, and postoperative recovery.

Cutaneous metastasis of transitional cell bladder carcinoma: a rare presentation and literature review.

2011-01-01

Cutaneous metastasis from transitional cell bladder carcinoma is a rare clinical entity associated with poor prognosis. We present a case of cutaneous metastasis arising from a transitional cell bladder carcinoma in a male patient who had undergone a radical cystectomy and bilateral ureterostomy 17 months previously. The cutaneous metastasis became evident 3 months before the manifestations of generalized recurrent disease. An awareness of this rare clinical entity and high index of suspicion is needed to rule out metastatic spread in patients with a previous history of transitional cell bladder carcinoma presenting with cutaneous nodules. Definitive diagnosis requires a histological confirmation, but prognosis is generally poor.

Perivascular epithelioid cell tumors (PEComa) are a very uncommon mesenchymal cancer with uncertain malignant potential. A computerized research on Pub Med was performed regarding bladder PEComa. We evaluated the literature cases and described a case of bladder PEComa. PEComa of the bladder is a very rare neoplasm and only 15 cases have been reported so far. Bladder PEComa involves young subjects of both genders, mostly under 40 years of age. Surgical treatment (partial or radical cystectomy) is the most common management.A long-term follow-up and larger series are required to better understand the best clinical approach to bladder PEComa.

The spongy body of the penis metastasis from other primary sites is a rare clinical entity. It is frequently associated with widespread metastatic disease and poor prognosis clinically. We report a case of a 61-year-old man with a previous history of cystectomy due to infiltrating urothelial carcinoma of the bladder 12 months ago and presented with penile shaft swelling pain and hematuria for 3 months. The restaging F-FDG PET/CT scan demonstrated a hypermetabolic mass at his penile shaft. This lesion was confirmed on phallectomy to be infiltrating urothelial carcinoma metastasis from the known primary bladder tumor.

Mesh fixation during laparoscopic totally extraperitoneal repair is thought to be necessary to prevent recurrence. However, mesh fixation may increase postoperative chronic pain. This study aimed to describe the experience of a single surgeon at our institution performing this operation. We performed a retrospective review of the medical records of all patients who underwent bilateral laparoscopic totally extraperitoneal repair without mesh fixation for inguinal hernia from January 2005 to December 2011. Demographic, operative, and postoperative data were obtained for analysis. A total of 343 patients underwent simultaneous bilateral laparoscopic totally extraperitoneal repair of 686 primary and recurrent inguinal hernias from January 2005 to December 2011. The mean operative time was 33 minutes. One patient was converted to an open approach (0.3%), and 1 patient had intraoperative bladder injury. Postoperative hematoma/seroma occurred in 5 patients (1.5%), wound infection in 1 (0.3%), hematuria in 2 (0.6%), and acute myocardial infarction in 1 (0.3%). Chronic pain developed postoperatively in 9 patients (2.6%); 3 of them underwent re-exploration. All patients were discharged home a few hours after surgery except for 3 patients. Among the 686 hernia repairs, there were a total of 20 recurrences (2.9%) in 18 patients (5.2%). Two patients had bilateral recurrences, whereas 16 had unilateral recurrences. Twelve of the recurrences occurred after 1 year (60%). Fourteen recurrences occurred among direct hernias (70%). Compared with the literature, our patients had fewer intraoperative and postoperative complications, less chronic pain, and no increase in operative time or length of hospital stay but had a slight increase in recurrence rate.

The Uterus-11 trial was designed to evaluate the role of surgical staging in patients with cervical cancer before primary chemoradiation therapy (CRT). The present report provides the toxicity data stratified by the treatment arm and technique. A total of 255 patients with carcinoma of the uterine cervix (International Federation of Gynecology and Obstetrics stage IIB-IVA) were randomized to either surgical staging followed by CRT (arm A) or clinical staging followed by CRT (arm B). Patients with para-aortic metastases underwent extended field radiation therapy (RT). Brachytherapy was mandatory. The present report presents the acute therapy-related toxicities stratified by treatment arm and radiation technique. A total of 240 patients were eligible (n=121 in arm A; n=119 in arm B). Of the 240 patients, 236 (98.3%) underwent external beam RT with a median total dose of 50.4 Gy. The mean treatment duration was 53 days. Of the patients, 60% underwent intensity modulated RT (IMRT). A total of 234 patients (97.5%) underwent chemotherapy, and 231 (96.3%) underwent brachytherapy, with a median single dose of 6 Gy covering the tumor to a median nominal total dose of 28 Gy. Treatment was well tolerated, with 0% grade ≥3 genitourinary and gastrointestinal toxicity, 6% grade 3 nausea, 3% grade 3 vomiting, and <2% grade 3 diarrhea. More patients after surgical staging experienced grade 2 anemia (54.3% in arm A vs 45.3% in arm B; P=.074) and grade 2 leukocytopenia (41.4% vs 31.6%; P=.56). Of the patients who received IMRT versus a 3-dimensional technique, 65.3% versus 33.7% presented with grade 2 anemia. Grade 3 gastrointestinal and grade 2 bladder toxicity were significantly reduced with the use of IMRT. The incidence and severity of acute therapy-related toxicity compared favorably with those from other randomized trials. Excellent adherence to treatment and treatment quality was achieved compared with patterns of care analyses. Surgical staging led to a doubled number of patients treated with extended field RT. The question of whether surgical staging is beneficial in the context of primary CRT requires further study. Copyright © 2016 Elsevier Inc. All rights reserved.

Objective To determine the rates of axillary lymph node dissection (ALND) and axillary irradiation (AI) in patients with breast cancer and to identify the factors influencing them. Summary Background Data Routine performance of ALND in the treatment of breast cancer has become controversial. AI has been proposed as an alternative to ALND, and it has been suggested that AI in addition to ALND may decrease local failure in high-risk patients. Methods A joint study was conducted by the Commission on Cancer of the American College of Surgeons and the American College of Radiology. A total of 17,151 patients with stage I and II breast cancer treated at 819 institutions in 1994 were studied. Results A total of 15,992 patients underwent ALND (93%). The mean ages of patients who did and did not undergo ALND were 60.4 and 73.0 years. Univariate analysis demonstrated significantly decreased rates of ALND for women age 70 or older (86%vs. 97%), patients with clinical T1a tumors (81%vs. 93%), grade I histology (90%vs. 95%), and patients with favorable tumor types (88%vs. 94%). The ALND rate did not vary between palpable and nonpalpable tumors. Multivariate analysis of variables affecting the rate of ALND identified type of surgery, age, tumor size, histology, and payer status as significant. A total of 889 patients received AI. Patients not undergoing ALND were more likely to receive AI (10%vs. 5%). A total of 1.6% of patients with no lymph node metastasis underwent AI, 8.9% of those with one to three positive nodes underwent AI, 24.0% of those with four to nine positive lymph nodes underwent AI, and 29.9% of those with ≥10 positive lymph nodes underwent AI. Multivariate analysis of variables affecting the proportion of patients who received AI and had undergone ALND identified nodal status and type of surgery as significant. Conclusions Axillary lymph node dissection continues to be routinely applied in the treatment of breast cancer, and AI remains underused in patients at high risk for local regional relapse.

Although pre-surgical orthodontic treatment has been accepted as a necessary process for stable orthognathic correction in the traditional orthognathic approach, recent advances in the application of miniscrews and in the pre-surgical simulation of orthodontic management using dental models have shown that it is possible to perform a surgery-first orthognathic approach without pre-surgical orthodontic treatment. This prospective study investigated the surgical outcomes of patients with diagnosed skeletal class III dentofacial deformities who underwent orthognathic surgery between December 2007 and December 2014. Cephalometric landmark data for patients undergoing the surgery-first approach were analyzed in terms of postoperative changes in vertical and horizontal skeletal pattern, dental pattern, and soft tissue profile. Forty-five consecutive Asian patients with skeletal class III dentofacial deformities who underwent surgery-first orthognathic surgery and 52 patients who underwent conventional two-jaw orthognathic surgery were included. The analysis revealed that the total treatment period for the surgery-first approach averaged 14.6 months, compared with 22.0 months for the orthodontics-first approach. Comparisons between the immediate postoperative and preoperative and between the postoperative and immediate postoperative cephalometric data revealed factors that correlated with the total treatment duration. The surgery-first orthognathic approach can dramatically reduce the total treatment time, with no major complications. Copyright © 2016 International Association of Oral and Maxillofacial Surgeons.

Background: Urethroplasty is often successful for the treatment of male urethral stricture disease, but limited data exists on recurrence management. Our goal was to evaluate direct visual internal urethrotomy (DVIU) as a treatment option for isolated, recurrent strictures after urethroplasty. Methods: We retrospectively identified male patients who underwent urethroplasty from 1999 to 2013 and developed an isolated, recurrent stricture at the urethroplasty site treated with DVIU. Success was defined as lack of symptomatology and no subsequent intervention. Comparative analysis identified characteristics and stricture properties associated with success. Results: A total of 436 urethroplasties were performed in 401 patients at our institution between 1999 and 2013. Stricture recurrence was noted in 64 (16%) patients. Of these, 47 (73%) underwent a DVIU. A total of 37 patients met inclusion criteria and underwent 50 DVIU procedures at the urethroplasty site. A single DVIU was successful in 13 of 37 patients (35%). A total of 4 of 6 patients required a second DVIU (67%). Overall, 17 of 43 (40%) of the total DVIUs were successful after urethroplasty. Success did not differ by age, stricture length or location, surgical technique, radiation history, prior urethroplasty or DVIU, time to failure, or etiology. Conclusions: Post-urethroplasty DVIU for isolated, recurrent strictures may be offered as a minimally invasive treatment option. Approximately 40% of patients were spared further intervention.

We determined factors associated with long-term outcomes of patients who underwent successful percutaneous mitral balloon valvuloplasty (PMV). Between August 1980 and May 2013, 1187 patients underwent PMV at Severance Hospital, Seoul, Korea. A total of 742 patients who underwent regular clinic visits for more than 10 years were retrospectively analyzed. The endpoints consisted of repeated PMV, mitral valve (MV) surgery, and cardiovascular-related death. The optimal result, defined as a post-PMV mitral valve area (MVA) >1.5 cm² and mitral regurgitation ≤Grade II, was obtained in 631 (85%) patients. Over a mean follow up duration of 214±50 months, 54 (7.3%) patients underwent repeat PMV, 4 (0.5%) underwent trido-PMV, and 248 (33.4%) underwent MV surgery. A total of 33 patients (4.4%) had stroke, and 35 (4.7%) patients died from cardiovascular-related reasons. In a multivariate analysis, echocardiographic score [p=0.003, hazard ratio=1.56, 95% confidence interval (CI): 1.01-2.41] and post-MVA cut-off (p<0.001, relative risk=0.39, 95% CI: 0.37-0.69) were the only significant predictors of long-term clinical outcomes after adjusting for confounding variables. A post-MVA cut-off value of 1.76 cm² showed satisfactory predictive power for poor long-term clinical outcomes. In this long-term follow up study (up to 20 years), an echocardiographic score >8 and post-MVA ≤1.76 cm² were independent predictors of poor long-term clinical outcomes after PMV, including MV reintervention, stroke, and cardiovascular-related death. © Copyright: Yonsei University College of Medicine 2018

2014-01-01

Background and Objectives: Mesh fixation during laparoscopic totally extraperitoneal repair is thought to be necessary to prevent recurrence. However, mesh fixation may increase postoperative chronic pain. This study aimed to describe the experience of a single surgeon at our institution performing this operation. Methods: We performed a retrospective review of the medical records of all patients who underwent bilateral laparoscopic totally extraperitoneal repair without mesh fixation for inguinal hernia from January 2005 to December 2011. Demographic, operative, and postoperative data were obtained for analysis. Results: A total of 343 patients underwent simultaneous bilateral laparoscopic totally extraperitoneal repair of 686 primary and recurrent inguinal hernias from January 2005 to December 2011. The mean operative time was 33 minutes. One patient was converted to an open approach (0.3%), and 1 patient had intraoperative bladder injury. Postoperative hematoma/seroma occurred in 5 patients (1.5%), wound infection in 1 (0.3%), hematuria in 2 (0.6%), and acute myocardial infarction in 1 (0.3%). Chronic pain developed postoperatively in 9 patients (2.6%); 3 of them underwent re-exploration. All patients were discharged home a few hours after surgery except for 3 patients. Among the 686 hernia repairs, there were a total of 20 recurrences (2.9%) in 18 patients (5.2%). Two patients had bilateral recurrences, whereas 16 had unilateral recurrences. Twelve of the recurrences occurred after 1 year (60%). Fourteen recurrences occurred among direct hernias (70%). Conclusion: Compared with the literature, our patients had fewer intraoperative and postoperative complications, less chronic pain, and no increase in operative time or length of hospital stay but had a slight increase in recurrence rate.

Anterior cervical discectomy and fusion (ACDF) is a well-accepted treatment option for patients with cervical spine disease. Three- and four-level discectomies are known to be associated with a higher complication rate and lower fusion rate than single-level surgery. This study was performed to evaluate and compare zero-profile fixation and stand-alone PEEK cages for three- and four-level ACDF. Two cohorts of patients who underwent ACDF for the treatment of three- and four-level disease were compared. Thirty-three patients underwent implantation of zero-profile devices that included titanium screw fixation (Group A). Thirty-five patients underwent implantation of stand-alone PEEK cages without any form of screw fixation (Group B). In Group A, twenty-seven patients underwent a three-level and six patients a four-level ACDF, with a total of 105 levels. In Group B, thirty patients underwent a three-level and five patients underwent a four-level ACDF, with a total number of 110 levels. In Group A, the mean preoperative visual analog scale score (VAS) for arm pain was 6.4 (range 3-8), and the mean postoperative VAS for arm pain decreased to 2.5 (range 1-7). In group B, the mean preoperative VAS of arm pain was 7.1 (range 3-10), and the mean postoperative VAS of arm pain decreased to 2 (range 0-4). In Group A, four patients (12%) developed dysphagia, and in Group B, three patients (9%) developed dysphagia.  Conclusions: This study found zero-profile instrumentation and PEEK cages to be both safe and effective for patients who underwent three- and four-level ACDF, comparable to reported series using plate devices. Rates of dysphagia for the cohort were much lower than reports using plate devices. Zero-profile segmental fixation devices and PEEK cages may be considered as viable alternatives over plate fixation for patients requiring multi-level anterior cervical fusion surgery.

This study explored the effects of general (GA) and neuraxial (NA) anesthesia on the outcomes of primary total joint replacement (TJR) in terms of postoperative mortality, length of stay (LOS), and hospital treatment costs. From 1997 to 2010, this nationwide population-based study retrospectively evaluated 7,977 patients in Taiwan who underwent primary total hip or knee replacement. We generated two propensity-score-matched subgroups, each containing an equal number of patients who underwent TJR with either GA or NA. Of the 7,977 patients, 2,990 (37.5%) underwent GA and 4,987 (62.5%) underwent NA. Propensity-score matching was used to create comparable GA and NA groups adjusted for age, sex, comorbidities, surgery type, hospital volume, and surgeon volume. Survival over the first three years following surgery was similar. The proportion of patients alive up to 14 years postoperatively for those undergoing NA was 58.2% (95% confidence interval [CI] 50.4 to 66.0), and for those undergoing GA it was 57.3% (95% CI 51.4 to 63.2). Neuraxial anesthesia was associated with lower median [interquartile range; IQR] hospital treatment cost ($4,079 [3,805-4,444] vs $4,113 [3,812-4,568]; P < 0.001) and shorter median [IQR] LOS (8 [7-10] days vs 8 [6-10] days, respectively; P = 0.024). Our results support the use of NA for primary TJR. The improvements in hospital costs persist even when anesthesia costs are removed. The mechanism underlying the association between NA and long-term survival is unknown.

Cribriform-morular variant of papillary thyroid carcinoma (CMV-PTC) is rare; it may occur in cases of familial adenomatous polyposis (FAP) or be sporadic. To clarify the clinicopathological features of CMV-PTC, the medical records of these patients were investigated retrospectively. Between 1979 and 2016, a total of 17,062 cases with PTC underwent initial surgery at Ito Hospital. Of these, 30 (0.2%) cases histologically diagnosed with CMV-PTC were reviewed. The patients were all women, with a mean age at the time of surgery of 24 years. Seven (23%) cases were thought to have FAP because they had colonic polyposis or a family history of FAP or APC gene mutation. The remaining 23 (77%) were thought to be sporadic. Multiple tumors were detected in 6 cases, with a solitary tumor in 24. One patient had lung metastasis at diagnosis. Eleven patients underwent total thyroidectomy or subtotal thyroidectomy, and 19 underwent lobectomy. Twenty-six (87%) patients underwent neck lymph node dissection. Three patients had tumor metastasis in central lymph nodes, but these were incidentally detected metastatic classical PTC (cPTC) based on histological examination. In this series, there were no cases of LN metastases of CMV-PTC. During a mean follow-up of 15 years, one patient had new cPTC in the remnant thyroid after initial surgery, and the other patients showed no signs of recurrence. CMV-PTC occurred in young women, their long-term prognosis was excellent. Total thyroidectomy is recommended for FAP-associated CMV-PTC, but modified neck lymph node dissection is not necessary.

Total thyroidectomy: safe and adequate treatment for papillary microcarcinoma of the thyroid gland. The purpose of this study was to evaluate the incidence of and surgical approach in patients with papillary thyroid microcarcinoma (PTMC; thyroid cancer s10 mm) when these patients underwent surgery for presumed benign thyroid conditions. Between January 2006 and December 2013, 1460 adult patients underwent partial or total thyroidectomy for presumed benign thyroid conditions in the Department of Otorhinolaryngology, Head and Neck Surgery, Comenius University, Jessenius Faculty of Medicine, University Hospital in Martin, Slovakia. Of this population, 78 patients with incidental PTMC were further studied. Incidental papillary microcarcinoma was more frequently detected in patients with multinodular goitre (P = 0.034) or Hashimoto's thyroiditis (P=0.00 13) than in patients with other thyroid diseases. Multifocal and bilateral occurance of PTMC was identified in 26% and 18% of patients, respectively. The initial surgical procedure was -hemithyroidectomy in 23% of patients. All patients initially treated with hemithyroidectomy underwent completion thyroidectomy 10-32 days (median 19 ±7 days) after initial surgery. There were no significant differences in postoperative complications (recurrent laryngeal nerve injury, hypoparathyroidism) between patients with hemithyroidectomy and patients with total thyroidectomy at the first operation (P = 0.647). Completion surgery in patients with hemithyroidectomy was not followed by a significant increase in the incidence of complications (P=0.228). Incidental PTMC is more often detected in patients that undergo surgery for multinodular goitre and Hashimoto's thyroiditis. Total thyroidectomy constitutes a safe and adequate surgical approach in patients with PTMC.

To evaluate pain control in chronic pancreatitis patients who underwent total pancreatectomy with islet cell transplantation or intrathecal narcotic pump infusion. We recognized 13 patients who underwent intrathecal narcotic pump (ITNP) infusion and 57 patients who underwent total pancreatectomy with autologous islet cell transplantation (TP + ICT) for chronic pancreatitis (CP) pain control between 1998 and 2008 at Indiana University Hospital. All patients had already failed multiple other modalities for pain control and the decision to proceed with either intervention was made at the discretion of the patients and their treating physicians. All patients were evaluated retrospectively using a questionnaire inquiring about their pain control (using a 0-10 pain scale), daily narcotic dose usage, and hospital admission days for pain control before each intervention and during their last follow-up. All 13 ITNP patients and 30 available TP + ICT patients were evaluated. The mean age was approximately 40 years in both groups. The median duration of pain before intervention was 6 years and 7 years in the ITNP and TP + ICT groups, respectively. The median pain score dropped from 8 to 2.5 (on a scale of 0-10) in both groups on their last follow up. The median daily dose of narcotics also decreased from 393 mg equivalent of morphine sulfate to 8 mg in the ITNP group and from 300 mg to 40 mg in the TP + ICT group. No patient had diabetes mellitus (DM) before either procedure whereas 85% of those who underwent pancreatectomy were insulin dependent on their last evaluation despite ICT. ITNP and TP + ICT are comparable for pain control in patients with CP however with high incidence of DM among those who underwent TP + ICT. Prospective comparative studies and longer follow up are needed to better define treatment outcomes.

Amiodarone is used commonly and effectively in the treatment of arrhythmia; however, it may cause thyrotoxicosis categorized into two types: iodine-induced hyperthyroidism (type 1 amiodarone-induced thyrotoxicosis (AIT)) and destructive thyroiditis (type 2 AIT). We experienced a case of type 2 AIT, in which high-dose steroid was administered intravenously, and we finally decided to perform total thyroidectomy, resulting in a complete cure of the AIT. Even though steroid had been administered to the patient (maximum 80 mg of prednisolone), the operation was performed safely and no acute adrenal crisis as steroid withdrawal syndrome was found after the operation. Few cases of type 2 AIT that underwent total thyroidectomy with high-dose steroid administration have been reported. The current case suggests that total thyroidectomy should be taken into consideration for patients with AIT who cannot be controlled by medical treatment and even in those under high-dose steroid administration.

The aim of the study was to compare the incidences of pharyngocutaneous fistula after total laryngectomy between patients who underwent manual and mechanical suturing for pharyngoesophageal closure. In a retrospective and prospective nonrandomized clinical study conducted at a single tertiary medical center between May 2002 and April 2009, we compared the incidence of pharyngocutaneous salivary fistula between two groups of patients after total laryngectomy. Sixty-one consecutive patients who underwent mechanical suturing with a 60-mm linear stapler (group A) were prospectively enrolled, and 121 patients who had undergone manual suturing (group B) were retrospectively reviewed. The groups were similar in terms of age, gender, comorbidities, TNM (tumor, node, metastasis) stage, and laryngeal tumor extension. The incidence of pharyngocutaneous salivary fistula was 4.9% in group A and 19.8% in group B (p = 0.014). Mechanical stapler closure of the pharynx after total laryngectomy was associated with a significant reduction in the incidence of pharyngocutaneous fistula compared with manual suture in selected cases.

Improved quality of life and sexuality with continent urinary diversion in quadriplegic women with umbilical stoma.

Quality of life issues prompted us to offer continent urinary diversion to quadriplegic women who required cystectomy for end-stage neurogenic vesical dysfunction complicated by urethral destruction as a result of chronic indwelling catheterization. Three women with spinal cord injury (SCI) and resultant quadriplegia of 5 to 15 years duration underwent continent urinary diversion. Preoperative evaluation and urodynamic studies in each showed a bladder capacity of less than 150mL, bilateral vesicoureteral reflux, recurrent febrile urinary tract infections, an incompetent urethral sphincter, and incontinence around an indwelling catheter in all three patients. Although highly motivated, these women showed minimal dexterity and were unable to perform urethral self-catheterization. Each was opposed to having an incontinent abdominal urinary stoma. The urinary reservoir was created from 30cm of detubularized right colon. The continence mechanism used an intussuscepted and imbricated ileocecal valve. The umbilicus was chosen as the urostomy site because of cosmetic appearance and ease of catheterization for a patient with minimal dexterity. Follow-up ranged from 18 to 30 months. Reservoir capacity ranged from 550 to 800mL without evidence of reflux or stomal leakage. The incidence of symptomatic autonomic dysreflexia and urinary tract infection decreased postoperatively in all patients. Of the two women who were sexually active, the frequency of activity increased from 8 to 15 episodes per month in one and 3 to 4 episodes per month in the other. Both reported improved sexual enjoyment. Body image and satisfaction with urologic management increased in all three patients. In conclusion, continent urinary diversion in selected quadriplegic patients is a reasonable alterative to incontinent intestinal urinary diversion. The umbilical stoma provides an excellent cosmetic result which patients with minimal dexterity are able to catheterize easily. Continent urinary diversion in women results in improved self-image, quality of life, and enables greater sexual satisfaction.

To classify patients with orthotopic neobladder based on urodynamic parameters using cluster analysis and to characterize the voiding function of each group. From January 2012 to November 2015, 142 patients with bladder cancer underwent radical cystectomy and Studer neobladder reconstruction at our institute. Of the 142 patients, 103 with complete urodynamic data and information on urinary functional outcomes were included in this study. K-means clustering was performed with urodynamic parameters which included maximal cystometric capacity, residual volume, maximal flow rate, compliance, and detrusor pressure at maximum flow rate. Three groups emerged by cluster analysis. Urodynamic parameters and urinary function outcomes were compared between three groups. Group 1 (n = 44) had ideal urodynamic parameters with a mean maximal bladder capacity of 513.3 ml and mean residual urine volume of 33.1 ml. Group 2 (n = 42) was characterized by small bladder capacity with low compliance. Patients in group 2 had higher rates of daytime incontinence and nighttime incontinence than patients in group 1. Group 3 (n = 17) was characterized by large residual urine volume with high compliance. When we examined gender differences in urodynamics and functional outcomes, residual urine volume and the rate of daytime incontinence were only marginally significant. However, females were significantly more likely to belong to group 2 or 3 (P = 0.003). In multivariate analysis to identify factors associated with group 1 which has the most ideal urodynamic pattern, age (OR 0.95, P = 0.017) and male gender (OR 7.57, P = 0.003) were identified as significant factors. While patients with ileal neobladder present with various voiding symptoms, three urodynamic patterns were identified by cluster analysis. Approximately half of patients had ideal urodynamic parameters. The other two groups were characterized by large residual urine and small capacity bladder with low compliance. Young age and male gender appear to have a favorable impact on urodynamic and voiding outcomes in patients undergoing orthotopic neobladder reconstruction.

The "Japanese guidelines for prevention of perioperative infections in urological field" was edited by the Japanese Urological Association in 2007. They are the first Japanese guidelines for antimicrobial prophylaxis specifically to prevent perioperative infections in the urological field. We report here the results of a multicenter prospective study conducted to examine the validity and usefulness of these guidelines. The subjects were 513 patients who had undergone urological surgeries between July and September 2008 at 10 nationwide university institutions in the Japanese Society of UTI Cooperative Study Group. These surgeries were transurethral resection of bladder (TURBT), transurethral resection of prostate (TURP), adrenalectomy, nephrectomy, nephroureterectomy, radical prostatectomy and total cystectomy. Analysis was performed on patient information, surgical procedures, types and durations of administration of prophylactic antibiotic agents, and the presence of surgical site infections (SSI) and remote infections (RI). Of 513 patients, 387 (75.4%) were administered prophylactic antibiotic agents according to the guidelines. In these patients, the incidences of SSI and RI were 5.9% and 4.1%, respectively. Multivariate analysis showed that significant factors for SSI were the surgical risk (according to the ASA physical status classification system), diabetes, and operation time, and that the only significant factor for RI was the operation time. More large-scale study and evidences are necessary in order to demonstrate the validity and usefulness of these guidelines.

Endocervicosis is a rare benign condition characterized by the presence of endocervical-type mucinous glands. Urinary bladder endocervicosis forms an elevated lesion in the posterior wall of the urinary bladder and is sometimes misdiagnosed as a malignant tumor clinically and pathologically. Herein we describe the first case of adenocarcinoma arising in urinary bladder endocervicosis. The patient, a 58-year-old woman, presented with asymptomatic hematuria. Cystoscopy revealed a nodular mass measuring 4 cm in diameter in the posterior wall, and total cystectomy was performed. Histology revealed that the elevated lesion of the bladder wall was composed of haphazard proliferation of cystic glands lined by benign endocervical-type epithelium. An adenocarcinoma arose at the center of this endocervicosis. Mucin histochemistry revealed the presence of sulfomucin in both the endocervicosis and adenocarcinoma components. Immunohistochemically, the endocervicosis was positive for cytokeratin (CK) 7, AE1/AE3, CAM5.2, HBME1, CA19-9, and estrogen receptor (ER), and negative for CK20, CDX2, progesterone receptor (PR), MUC5AC, and β-catenin. The adenocarcinoma showed similar immunohistochemical results, except for loss of ER expression and a slight increase in the ratio of Ki-67-positive cells. This case indicates that endocervicosis, known as a benign lesion, harbors the possibility of malignant transformation. © 2016 The Authors.

An accurate diagnosis of acute appendicitis is important to avoid severe outcome or unnecessary surgery but management is controversial. The aim of study was to evaluate, in younger and older children, the efficacy of conservative management for uncomplicated appendicitis and the outcome of complicated forms underwent early surgery. Children with acute appendicitis were investigated by clinical, laboratory variables and abdominal ultrasound and divided in two groups: complicated and uncomplicated. Complicated appendicitis underwent early surgery; uncomplicated appendicitis started conservative treatment with antibiotic. If in the next 24-48h it was worsening, the conservative approach failed and patients underwent late surgery. A total of 362 pediatric patients were included. One hundred sixty-five underwent early appendectomy; 197 patients were at first treated conservatively: of these, 82 were operated within 24-48h for failure. The total percentage of operated patients was 68.2%. An elevated association was found between surgery and ultrasound. Conservative treatment for uncomplicated appendicitis had high percentage of success (58%). Complications in operated patients were infrequent. Our protocol was effective in order to decide which patients treat early surgically and which conservatively; specific red flags (age and onset) can identified patients at most risk of complications or conservative failure. treatment study.

In arthroplasty data, patients with staged bilateral total joint arthroplasty (TJA) pose a problem in statistical analysis. Subgroup analysis, in which patients with unilateral and bilateral TJA are studied separately, is sometimes considered an appropriate solution to the problem; we aim to show that this is not true because of immortal time bias. We reviewed patients who underwent staged (at any time) bilateral TJA. The logical fallacy leading to immortal time bias is explained through a simple artificial data example. The cumulative incidences of revision and death are computed by subgroup analysis and by landmark analysis based on hip replacement data from the Dutch Arthroplasty Register and on simulated data sets. For patients who underwent unilateral TJA, subgroup analysis can lead to an overestimate of the cumulative incidence of death and an underestimate of the cumulative incidence of revision. The reverse conclusion holds for patients who underwent staged bilateral TJA. Analysis of these patients can lead to an underestimate of the cumulative incidence of death and an overestimate of the cumulative incidence of revision. Immortal time bias can be prevented by using landmark analysis. When examining arthroplasty registry data, patients who underwent staged bilateral TJA should be analyzed with caution. An appropriate statistical method to address the research question should be selected.

We share our experience on reconstructive for surgery female genital mutilation. This is a retrospective study of all cases of female genital mutilation surgery performed in Pikine National Hospital. We have reviewed the various indications and surgical techniques used. We collected 8 cases of clitoral cyst and 6 cases of closed vaginal opening. The surgery of clitoral cysts was to perform cystectomy followed by nymphoplasty. The closing of the vaginal opening required defibulation together with clitoroplasty according to the wishes of the patient. The anatomical and functional outcomes were satisfactory. Female genital mutilation surgery requires a good knowledge of vulvar anatomy. The various surgical indications must meet the expectations of patients to guarantee their satisfaction.

Trimodality therapy in bladder cancer: Who, what and when?

Summary Radical cystectomy is a standard treatment for non-metastatic, muscle-invasive bladder cancer. Treatment with trimodality therapy consisting of maximal transurethral resection of the bladder tumor (TURBT) followed by concurrent chemotherapy and radiation has emerged as a method to preserve the native bladder in highly motivated patients. A number of factors can impact the likelihood of long term bladder preservation after trimodality therapy, and therefore should be taken into account when selecting patients. New radiation techniques such as intensity modulated radiation therapy and image guided radiation therapy may decrease the toxicity of radiotherapy in this setting, but remain an area of active study. Novel chemotherapy regimens may improve response rates and minimize toxicity. PMID:25882559

Superficial and muscle-invasive bladder cancer: principles of management for outcomes assessments.

Bladder cancer is a heterogeneous disease. Non-muscle-invasive bladder cancer embraces a spectrum of tumors with varying degrees of clinical behavior. Transurethral resection remains the surgical mainstay for the treatment of non-muscle-invasive bladder cancer. In an attempt to decrease the recurrence or progression rate, intravesical chemotherapy or immunotherapy is also used. Radical cystectomy with bilateral pelvic lymph node dissection remains the gold standard for treating muscle-invasive bladder cancer. Over the last decade, the orthotopic neobladder has gained widespread popularity as the preferred mode of urinary diversion in both males and females with similar oncologic and functional outcomes. Well-designed trials with effective chemotherapy have shown a beneficial role for neoadjuvant chemotherapy.

The management of failed ankle replacement.

Advances in the design of the components for total ankle replacement have led to a resurgence of interest in this procedure. Between January 1999 and December 2004, 16 patients with a failed total ankle replacement were referred to our unit. In the presence of infection, a two-stage salvage procedure was planned. The first involved the removal of the components and the insertion of a cement spacer. Definitive treatment options included hindfoot fusion with a circular frame or amputation. When there was no infection, a one-stage salvage procedure was planned. Options included hindfoot fusion with an intramedullary nail or revision total ankle replacement. When there was suspicion of infection, a percutaneous biopsy was performed. The patients were followed up for a minimum of 12 months. Of the 16 patients, 14 had aseptic loosening, five of whom underwent a revision total ankle replacement and nine a hindfoot fusion. Of the two with infection, one underwent fusion and the other a below-knee amputation. There were no cases of wound breakdown, nonunion or malunion. Management of the failed total ankle replacement should be performed by experienced surgeons and ideally in units where multidisciplinary support is available. Currently, a hindfoot fusion appears to be preferable to a revision total ankle replacement.

To compare the long-term results of total and partial fundoplication on esophagus myotomy. From January 1978 to October 1998, 64 patients with achalasia or diffuse esophageal spasm underwent esophagomyotomy and antireflux operation via left thoracotomy. Twenty-one patients underwent Nissen total fundoplication (Nissen group) and 43 patients underwent Belsey Marker IV partial fundoplication (Belsey group). Clinical, radiologic, radionuclide transit, manometric, 24-hour pH monitoring and endoscopic assessments were performed before and after the operation. There was no operative death and major complications for either group. At over 6 years follow-up and compared to Belsey group, patients in Nissen group revealed a higher frequency of dysphagia (P = 0.025) and more radionuclide material retention (P = 0.044). Both operative procedures reduced the lower esophageal sphincter pressure gradient. However, in Nissen group, the esophageal diameter observed on radiology was significantly increased from 3.9 cm preoperatively to 5.5 cm postoperatively (P = 0.012), while it kept the same for Belsey group (from 5.4 to 5.3 cm, P = 0.695). Reoperation in order to relieve the recurrent dysphagia and esophageal obstruction was performed on 8 patients in Nissen group and 1 in Belsey group (P < 0.01). When treating achalasia or diffuse esophageal spasm by esophageal myotomy and an antireflux operation, a total fundoplication is not appropriate, whereas a partial fundoplication provides proper antireflux effect without significant esophageal emptying difficulty.

Duplex ultrasound is routinely used to evaluate suspected deep venous thrombosis after total joint arthroplasty. When there is a clinical suspicion for a pulmonary embolism, a chest angiogram (chest CTA) is concomitantly obtained. Two questions were addressed: First, for the population of patients who receive duplex ultrasound after total joint arthroplasty, what is the rate of positive results? Second, for these patients, how many of these also undergo chest CTA for clinical suspicion of pulmonary embolus and how many of these tests are positive? Furthermore, what is the correlation between duplex ultrasound results and chest CTA results? A retrospective chart review was conducted of total joint replacement patients in 2011 at a single institution. Inclusion criteria were adult patients who underwent a postoperative duplex ultrasonography for clinical suspicion of deep venous thrombosis (DVT). Demographic data, result of duplex scan, clinical indications for obtaining the duplex scan, and DVT prophylaxis used were recorded. Additionally, if a chest CTA was obtained for clinical suspicion for pulmonary embolus, results and clinical indication for obtaining the test were recorded. The rate of positive results for duplex ultrasonography and chest CTA was computed and correlated based on clinical indications. Two hundred ninety-five patients underwent duplex ultrasonography of which only 0.7% were positive for a DVT. One hundred three patients underwent a chest CTA for clinical suspicion of a pulmonary embolism (PE) of which 26 revealed a pulmonary embolus, none of which had a positive duplex ultrasound. Postoperative duplex scans have a low rate of positive results. A substantial number of patients with negative duplex results subsequently underwent chest CTA for clinical suspicion for which a pulmonary embolus was found, presumably resulting from a DVT despite negative duplex ultrasound result. A negative duplex ultrasonography should not rule out the presence of a DVT which can embolize to the lungs and thus should not preclude further workup when clinical suspicion exists for a pulmonary embolus.

Role of Surgical Versus Clinical Staging in Chemoradiated FIGO Stage IIB-IVA Cervical Cancer Patients—Acute Toxicity and Treatment Quality of the Uterus-11 Multicenter Phase III Intergroup Trial of the German Radiation Oncology Group and the Gynecologic Cancer Group

Purpose: The Uterus-11 trial was designed to evaluate the role of surgical staging in patients with cervical cancer before primary chemoradiation therapy (CRT). The present report provides the toxicity data stratified by the treatment arm and technique. Methods and Materials: A total of 255 patients with carcinoma of the uterine cervix (International Federation of Gynecology and Obstetrics stage IIB-IVA) were randomized to either surgical staging followed by CRT (arm A) or clinical staging followed by CRT (arm B). Patients with para-aortic metastases underwent extended field radiation therapy (RT). Brachytherapy was mandatory. The present report presents the acute therapy-related toxicities stratifiedmore » by treatment arm and radiation technique. Results: A total of 240 patients were eligible (n=121 in arm A; n=119 in arm B). Of the 240 patients, 236 (98.3%) underwent external beam RT with a median total dose of 50.4 Gy. The mean treatment duration was 53 days. Of the patients, 60% underwent intensity modulated RT (IMRT). A total of 234 patients (97.5%) underwent chemotherapy, and 231 (96.3%) underwent brachytherapy, with a median single dose of 6 Gy covering the tumor to a median nominal total dose of 28 Gy. Treatment was well tolerated, with 0% grade ≥3 genitourinary and gastrointestinal toxicity, 6% grade 3 nausea, 3% grade 3 vomiting, and <2% grade 3 diarrhea. More patients after surgical staging experienced grade 2 anemia (54.3% in arm A vs 45.3% in arm B; P=.074) and grade 2 leukocytopenia (41.4% vs 31.6%; P=.56). Of the patients who received IMRT versus a 3-dimensional technique, 65.3% versus 33.7% presented with grade 2 anemia. Grade 3 gastrointestinal and grade 2 bladder toxicity were significantly reduced with the use of IMRT. Conclusions: The incidence and severity of acute therapy-related toxicity compared favorably with those from other randomized trials. Excellent adherence to treatment and treatment quality was achieved compared with patterns of care analyses. Surgical staging led to a doubled number of patients treated with extended field RT. The question of whether surgical staging is beneficial in the context of primary CRT requires further study.« less

Results and complications of adolescent varicocele repair with intraoperative sodium morrhuate sclerotherapy.

Adolescent varicocele has been shown to affect spermatogenesis and correlate with decreased ipsilateral testicular volume, prompting treatment in a select population. We report our experience with 3 varicocele ligation procedures in concordance with sclerotherapy in adolescent patients. A total of 120 males underwent varicocele surgery at our institutions during an 8-year period. Sodium morrhuate sclerotherapy was used in 91 patients and 73 adolescent males fulfilled the 6-month followup criteria. The 73 males who were 9 to 17 years old underwent a total of 75 (bilateral in 2) procedures for varicocele treatment. Of the patients 23 underwent subinguinal microscopic varicocelectomy (group 1), 9 underwent loupe assisted subinguinal varicocelectomy (group 2) and 41 underwent loupe assisted inguinal varicocelectomy (group 3). All patients received intraoperative sclerotherapy using sodium morrhuate injection. Outcome measures included recurrence, complications and catch-up growth at a minimum of 6 months of followup. The varicocele recurrence rate was 2.7% in patients receiving combined surgical ligation and sclerotherapy ablation. Group 1 had 2 recurrent varicoceles and no hydrocele formation, group 2 had no varicocele recurrence and no hydrocele formation, and group 3 had no varicocele recurrence and 2 postoperative hydroceles. Catch-up growth in the ipsilateral testis was seen in 85% of patients. No atrophy or testicular loss was noted. This preliminary experience with combined surgical ligation and sclerotherapy ablation in the adolescent population resulted in low varicocele recurrence with minimal morbidity. Outcomes of loupe assisted varicocelectomy appear to be improved compared to those in previous studies, alluding to an advantage in the addition of sclerotherapy.

This single center retrospective study reviews the management and outcomes of 117 consecutive patients with humeral shaft fractures and associated radial nerve palsy (RNP) treated over a 20-year period (1986-2006). A total of 101 fractures were managed conservatively and 16 fractures underwent external fixation for poor bony alignment. Sixteen grade 1 and 2 open fractures underwent wound toileting alone. No patients underwent initial radial nerve exploration or opening of the fracture sites. All patients achieved clinical and radiological bony union at a mean of 8 weeks (range 7-12 weeks). There were no complications or pin tract infections in the operated patients. A total of 111 cases had initial spontaneous RNP recovery at a mean of 6 weeks (range 3-24 weeks) with full RNP recovery at a mean of 17 weeks (range 3-70 weeks) post-injury. Fourteen patients had no clinical/EMG signs of nerve activity at 12 weeks and 6 subsequently failed to regain any radial nerve recovery; 2 had late explorations and the lacerated nerves underwent sural nerve cable neurorraphy; and 4 patients underwent delayed tendon transposition 2-3 years after initial injury, with good/excellent functional outcomes. Humeral fractures with associated RNP may be treated expectantly. With low rates of humeral nonunion, 95% spontaneous nerve recovery in closed fractures and 94% in grade 1 and 2 open fractures, one has the opportunity of waiting. If at 10-12 weeks there are no clinical/EMG signs of recovery, then nerve exploration/secondary reconstruction is indicated. Late tendon transfers may also give good/excellent functional results.

In the past decade, adjuvant chemotherapy (AC) after radical cystectomy (RC) was preferred worldwide for patients with muscle-invasive urothelial bladder cancer. In this study we aimed to determine the outcome of patients who received AC and evaluated prognostic factors associated with survival. We retrospectively analyzed 226 consecutive patients treated in 6 academic hospitals between 2000 and 2009. Multivariate Cox proportional hazards regression adjusted for center to estimate adjusted hazard ratios (HRs) with 95% confidence intervals were used. The median age was 62.4 (range, 35-82) years. Patients had pT3/pT4 and/or pN+ in 180 (79.6%) and 168 patients (74.3%), respectively. Median lymph node (LN) density was 25% (range, 3.1-100). Median time between RC and AC was 61.5 (range, 18-162) days. Gemcitabine with cisplatin, gemcitabine with carboplatin, and MVAC (methotrexate, vinblastine, doxorubicin, and cisplatin) regimens were delivered in 161 (71.2%), 49 (21.7%), and 12 patients (5.3%) of patients, respectively. The median number of cycles was 4 (range, 1-6). Thirteen patients (5.7%) with LN metastases also received adjuvant pelvic radiotherapy (ART). After a median follow-up of 4.2 years, 5-year overall survival (OS) was 40.7%. In multivariate analysis, pT ≥3 stage (HR, 1.73; P = .05), LN density >50% (HR, 1.94; P = .03), and number of AC cycles <4 (HR, 4.26; P = .001) were adverse prognostic factors for OS. ART (HR, 0.30; P = .05) tended to provide survival benefit. Classical prognostic features associated with survival are not modified by the use of AC. Patients who derived benefit from AC had a low LN density and received at least 4 cycles of treatment. Copyright © 2016 Elsevier Inc. All rights reserved.

To identify which patients with macroscopic bladder-infiltrating T4 prostate cancer (PCa) might have favourable outcomes when treated with radical cystectomy (RC). We evaluated 62 patients with cT4cN0-1 cM0 PCa treated with RC and pelvic lymph node dissection between 1972 and 2011. In addition to descriptive statistics, the Kaplan-Meier method and log-rank tests were used to depict survival rates. Univariate and multivariate Cox regression analysis tested the association between predictors and progression-free, PCa-specific and overall survival. Of the 62 patients, 19 (30.6%) did not have clinical progression during follow-up, two (3.2%) had local recurrence, and 32 (51.6%) had haematogenous and nine (14.5%) combined pelvic and distant metastasis. Forty patients (64.5%) died, 34 (54.8%) from PCa and six (9.7%) from other causes. The median (range) survival time of the 19 patients who were metastasis-free at last follow-up was 86 (1-314) months, 8/19 patients had a follow-up of >5 years, and five patients survived metastasis-free for >15 years. Patients without seminal vesicle invasion (SVI) had the best outcomes, with an estimated 10-year PCa-specific survival of 75% compared with 24% for patients with SVI. For cT4 PCa RC can be an appropriate treatment for local control and part of a multimodality-treatment approach. Although recurrences are probable, these do not necessarily translate into cancer-specific death. Men without SVI had a 75% 10-year PCa-specific survival. Although outcomes for patients with SVI are not as favourable, there can be good local control; however, these patients are at higher risk of progression and may need more aggressive systemic treatment. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

Femtosecond laser ablation of porcine intestinal mucosa: potential autologous transplant for segmental cystectomy

Nearly 80% of patients with newly diagnosed bladder cancer present with superficial bladder tumors (confined to the bladder lining such as transitional cell carcinoma [90%], squamous cell carcinoma [6-8%], and adenocarcinoma[2%]) in stages Ta, Tis, or T1. Segmental cystectomy is one surgical treatment for patients who have a low-grade invasive tumor. Transposition of small intestine is a viable surgical treatment option. Success of the transplantation is also dependent upon removal of the entire SI mucosal layer. A Clark Spitfire Ti:Sapphire laser operating at 775 nm and 1 kHz repetition rate, was used to investigate the damage induced to fresh cadaveric porcine small intestinal mucosal epithelium. The laser was held constant at a focal spot diameter of 100 μm using a 200 mm focal point lens, with a power output maximum of 257 mW. A high resolution motorized X-Y-Z stage translated the SI tissue through the beam at 500 μm/sec with a line spacing of 50 μm. This produced a 50% overlap in the laser etching for each pass over a 1 cm x 1.5 cm grid. To determine if the mucosal lining of the SI was adequately removed, the targeted area was covered with 1% fluorescein solution for 30 seconds and then rinsed with phosphate buffered saline. Fluorescein staining was examined under UV illumination, to determine the initial degree of mucosal removal. Tissues were fixed and processed for light and scanning electron microscopy by standard protocols. Brightfield light microscopy of hematoxylin and eosin stained 4 μm thick cross sections, scanning electron microscopy were examined to determine the degree of mucosal tissue removal. Clear delineation of the submucosal layer by fluorescein staining was also observed. The Ti:Sapphire laser demonstrated precise, efficient removal of the mucosal epithelium with minimal submucosal damage.

The need to prevent reflux in the construction of an orthotopic ileal neobladder is controversial. We designed the USC-STAR trial to determine whether the T-pouch neobladder that included an antireflux mechanism was superior to the Studer pouch in patients with bladder cancer undergoing radical cystectomy. This single center, randomized, controlled trial recruited patients with clinically nonmetastatic bladder cancer scheduled to undergo radical cystectomy with neobladder. Eligible patients were randomly assigned to undergo T-pouch or Studer ileal orthotopic neobladder. Treatment assignment was not masked. The primary end point was change in renal function from baseline to 3 years. The CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) equation was used to calculate the estimated glomerular filtration rate. Between February 2002 and November 2009, 237 patients were randomly assigned to T-pouch ileal orthotopic neobladder and 247 to Studer ileal orthotopic neobladder. Baseline characteristics did not differ between the groups. Between baseline and 3 years the estimated glomerular filtration rate decreased by 6.4 ml/minute/1.73 m(2) in the Studer group and 6.6 ml/minute/1.73 m(2) in the T-pouch group (p=0.35). Multivariable analysis showed that type of ileal orthotopic neobladder was not independently associated with 3-year renal function (p=0.63). However, baseline estimated glomerular filtration rate, age and urinary tract obstruction were independently associated with 3-year decline in renal function. Cumulative risk of urinary tract infection and overall late complications were not different between the groups, but the T-pouch was associated with an increased risk of secondary diversion related surgeries. T-pouch ileal orthotopic neobladder with an antireflux mechanism did not prevent a moderate reduction in renal function observed at 3 years compared to the Studer pouch, but did result in an increase in diversion related secondary surgical procedures.

Orthotopic neobladder (ONB) and ileal conduit (IC) are the most commonly practiced techniques of urinary diversion (UD) after radical cystectomy (RC) in bladder cancer patients. Data in the literature is still discordant regarding which UD technique offers the best HR-QoL. The objective was to compare HR-QoL in patients undergoing ONB and IC after RC, through a systematic review of the literature and meta-analysis. We performed a literature search of PubMed, ScienceDirect, CochraneLibrary and ClinicalTrials.Gov in September 2017 according to the Cochrane Handbook and the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes. The studies were evaluated according to the "Oxford Center for Evidence-Based Medicine" criteria. The outcome measures evaluated were subdomains' scores of Bladder Cancer Index BCI: urinary function (UF), urinary bother (UB), bowel function (BF), bowel bother (BB), sexual function (SF) and sexual bother (SB). Continuous outcomes were compared using weighted means differences, with 95% confidence intervals. The presence of publication bias was examined by funnel plots. Four studies met the inclusion criteria. The pooled results demonstrated better UF and UB scores in IC patients: differences were -18.17 (95% CI: -27.49, -8.84, P=0.0001) and -3.72 (95% CI: -6.66, -0.79, P=0.01) respectively. There was no significant difference between IC and ONB patients in terms of BF and BB. SF was significantly better in ONB patients: the difference was 12.7 (95% CI, 6.32, 19.08, P<0.0001). However no significant difference was observed regarding SB. This meta-analysis of non-randomized studies demonstrated a better HR-QoL in urinary outcomes in IC patients compared with ONB patients.

Bladder cancer patients undergoing radical cystectomy and urinary diversion are faced with difficult decisions regarding mode of urinary diversion. Although these patients may use the Internet as a guide to diagnosis and treatment options, online resources remain largely unregulated leading to a great variation in quality of medical information. Further variation in quality is seen between languages. Fortunately, tools such as an automated toolbar developed by the World Health Organization Health on the Net (HON) Foundation exist to assist physicians in recommending quality online health information to patients. We set out to compare and assess the quality of bladder cancer, ileal conduit and orthotopic neobladder web sites in 2016 on the basis of the HON principles for English language. The Google search engine imbedded with the HON toolbar was used to assess 1350 Web sites using the keywords "bladder cancer", "ileal conduit" and "orthotopic neobladder" in English, Italian and Spanish. The first 150 results of each search were identified and screened. A further analysis was completed comparing results between 2009 and 2016. Less than 20% of English, Italian and Spanish "bladder cancer" and urinary diversion ("ileal conduit" and "orthotopic neobladder") web sites are HON-accredited. HON-accredited web sites featured preferentially in the first 50 search results for bladder cancer (P=0.0001) and ileal conduit (P=0.03) web sites. Comparing 2016 results to 2009, percentage of HON-accreditation has not shown statistically significant change (-13%, P=0.23), while overall number of search results has increased (+44%). A lack of validation of bladder cancer sites is present, which is consistent across modes of urinary diversion (orthotopic neobladder and ileal conduit) and languages. It is important that physicians involved in the care of bladder cancer patients undergoing radical cystectomy and urinary diversion participate in the development of informative, ethical, and reliable health Web sites and direct patients to them.

In bladder cancer, stage T2 is an important threshold in the decision of administering neoadjuvant chemotherapy. Our long-term goal is to develop a quantitative computerized decision support system (CDSS-S) to aid clinicians in accurate staging. In this study, we examined the effect of stage labels of the training samples on modeling such a system. We used a data set of 84 bladder cancers imaged with CT Urography (CTU). At clinical staging prior to treatment, 43 lesions were staged as below stage T2 and 41 were stage T2 or above. After cystectomy and pathological staging that is considered the gold standard, 10 of the lesions were upstaged to stage T2 or above. After correcting the stage labels, 33 lesions were below stage T2, and 51 were stage T2 or above. For the CDSS-S, the lesions were segmented using our AI-CALS method and radiomic features were extracted. We trained a linear discriminant analysis (LDA) classifier with leave-one-case-out cross validation to distinguish between bladder lesions of stage T2 or above and those below stage T2. The CDSS-S was trained and tested with the corrected post-cystectomy labels, and as a comparison, CDSS-S was also trained with understaged pre-treatment labels and tested on lesions with corrected labels. The test AUC for the CDSS-S trained with corrected labels was 0.89 +/- 0.04. For the CDSS-S trained with understaged pre-treatment labels and tested on the lesions with corrected labels, the test AUC was 0.86 +/- 0.04. The likelihood of stage T2 or above for 9 out of the 10 understaged lesions was correctly increased for the CDSS-S trained with corrected labels. The CDSS-S is sensitive to the accuracy of stage labeling. The CDSS-S trained with correct labels shows promise in prediction of the bladder cancer stage.

The objective of this study was to address the efficacy of transversus abdominis plane (TAP) blocks in pain management among women who undergo elective hysterectomy for benign pathology in both open and minimally invasive surgeries. We performed a systematic review by searching for bibliographic citations from Medline, Embase and Cochrane Library. MeSH headings for TAP blocks and hysterectomy were combined and restricted to the English language. We included RCTs comparing TAP blocks to placebo or no block in patients who underwent elective hysterectomy. Pain was measured using a visual analog score (VAS) on a scale of 0-100. We calculated pooled mean differences in VAS and total morphine consumption at 2 and 24 hours by performing a random effects meta-analysis. Fourteen studies met the inclusion criteria, comprising 855 participants. At 2 hours, mean VAS scores for patients who underwent TAP blocks were significantly lower after both total abdominal hysterectomy (TAH) (mean difference -14.97 [CI: -20.35- -9.59]) and total laparoscopic hysterectomy (TLH) (-18.16 [CI: -34.78- -1.53]) compared to placebo or no block. Pain scores at 24 hours for patients who underwent TAPB were significantly lower after both TAH (-10.09 [CI: -17.35- -2.83]) and TLH (-9.12 [CI: -18.12- -0.13]) compared to placebo or no block. Mean difference in morphine consumption was -9.53 mg (CI -15.43- -3.63) for TAH and -3.15 mg (CI: -8.41- 2.12) for TLH. In conclusion, TAP blocks provide significant postoperative early and delayed pain control compared to placebo or no block among women who undergo hysterectomy. There was reduced morphine consumption among patients who underwent TAH, but not after TLH. Copyright © 2018. Published by Elsevier Inc.

Summary This is a study of 120 patients of either sex and all ages who had sustained deep burns of up to 40% of the total body surface area. Half the patients underwent early excision and skin autografting (i.e., within 4-7 days of sustaining burn injury) while the rest underwent delayed excision and skin autografting (i.e., within 1-4 weeks post-burn). Significant differences were found in favour of the early excision and grafting group with regard to the various burn management outcome parameters taken into consideration, i.e. culture positivity of wounds, graft take, duration of post-graft hospitalization, and mortality.

Most publications on atrial isomerism are autopsy or case reports. The authors review 41 consecutive children operated on from 1980 through to 1996 with emphasis on associated cardiac anomalies, surgical procedures and outcome. Left atrial isomerism was present in 23 patients. Interruption of the inferior vena cava (56%), atrio-ventricular septal defect (47%), common atrium (38%) and cor triatriatum sinistrum (30%) were the most common diagnoses. Biventricular repair was achieved in 17 children and total cavo-pulmonary connection in two. Three underwent staged palliation: modified Blalock-Taussig shunt for two and bidirectional Glenn anastomosis for one. The remainder received a cardiac pacemaker. One patient died early after repair. Two underwent reoperation to correct a regurgitant left atrio-ventricular valve: one of these, in another hospital, had peroperative death. Three died later. Actuarial survival rate after repair and total cavo-pulmonary connection that was stabilized after 2 years was 84%. In the 18 children with right atrial isomerism, pulmonary atresia or stenosis predominated (89%) with discordant ventriculo-arterial connection (72%), atrio-ventricular septal defect (72%), 'single' ventricle (55%) and extracardiac total anomalous pulmonary venous drainage (50%). Biventricular repair was achieved in two patients and complete Fontan circulation in eight. The other eight underwent various staged palliative procedures and correction of extracardiac total anomalous pulmonary venous drainage. Five patients died postoperatively: two in our unit after modified Blalock-Taussig shunt and total cavo-pulmonary connection, three in other hospitals after repair (n = 1) and Fontan (n = 2). Five died later. One was lost for review. Survival after repair and Fontan stabilized after 6 months at 49%. In conclusion, the cardiovascular malformations associated with left atrial isomerism can often be successfully corrected. Those accompanying right atrial isomerism usually preclude a biventricular repair, require staged palliation and carry a poor prognosis.

Although single-incision laparoscopic cholecystectomy (SILC) has no advantage over conventional laparoscopic cholecystectomy (LC), except for better cosmesis, few reports have discussed the criteria for SILC. The aim of this study was to evaluate the suitability of our criteria for SILC. During the study period, SILC was performed at our institution under the following criteria. The inclusion criteria were elective surgery, age of < 60 years, and body mass index of < 30 kg/m 2 . The exclusion criteria were a thick gallbladder wall, history of choledocholithiasis, previous abdominal surgery, and serious concomitant disease. We reviewed data regarding consecutive patients who underwent LC at our institution from November 2009 to March 2016. The data were assessed with respect to patient characteristics, operative data, and postoperative outcomes. A total of 1093 patients underwent elective LC, and 232 (21.2%) of these patients underwent SILC using our criteria. Fourteen patients (6.0%) who underwent SILC required extra ports. Among the patients aged < 60 years, 50.2% (232/462) underwent SILC. There were few adverse events, including intra- and postoperative complications, among the patients who underwent SILC. The above-mentioned criteria are safe, necessary, and sufficient for SILC over conventional LC. Copyright © 2016. Published by Elsevier Taiwan.

Objectives: The objective was to compare conventional circular yttrium aluminum garnet (YAG) laser capsulotomy with hinged capsulotomy to manage posterior capsular opacification (PCO). Materials and Methods: This prospective, randomized clinical trial enrolled pseudophakic patients with visually significant posterior capsule opacification. Patients were randomized to undergo posterior YAG laser capsulotomy with either conventional circular technique or a new technique with an inferior hinge. At 1-month postoperatively, patients were asked if they had any annoying floaters and the responses were compared between groups. P < 0.05 was considered statistically significant. Results: A total of 83 patients were enrolled. Forty-three patients underwent hinged posterior YAG capsulotomy and 40 patients underwent routine circular capsulotomy. At 1-month postoperatively, there was a statistically significant decrease in annoying floaters in the group that underwent circular capsulotomy (P = 0.02). There was no statistically significant association in the total energy delivered (P = 0.4) or the number of spots (P = 0.2) and patient perception of annoying floaters. Conclusion: Hinged YAG capsulotomy was effective at decreasing the rate of floaters in patients with PCO. PMID:26180476

To evaluate the incidence of thyroid carcinoma in patients operated on for Graves' disease, to identify criteria which may predict malignancy, and to develop a practical approach to determine the extensiveness of thyroidectomy. Retrospective study of all patients who underwent thyroidectomy for Graves' disease between 1995 and 2005. 547 patients underwent subtotal thyroidectomy for Graves' disease during this period. Post-operative pathology examination revealed six cases of thyroid cancer (1.1%). All six cases had differentiated thyroid carcinoma (papillary carcinoma in 3 cases, follicular carcinoma in 2 cases and papillo-follicular carcinoma in 1 case). The indication for initial thyroidectomy was a palpable thyroid nodule in 3 cases (50%), failure of medical treatment for Grave's disease in 2 cases (33%), and signs of goiter compression in 1 case (17%). Five patients underwent re-operative total thyroidectomy. This study shows that while malignancy in Grave's disease is uncommon, the presence of thyroid nodule(s) in patients with Grave's disease may be considered as an indication for radical surgery. The most adequate radical surgery in this situation is to perform a total thyroidectomy.

Total pelvic exenteration (TPE) is reserved for patients with locally invasive and recurrent pelvic malignancies. Complications such as wound infections, dehiscence, hernias, abscesses, and fistulas are common after this procedure. The purpose of this study was to determine whether tissue transfer to the pelvis after TPE decreases wound complications. Fifty-three patients who underwent TPE between 2004 and 2010 were reviewed. Two groups were identified, those who underwent pelvic reconstruction with a vertical rectus abdominus myocutaneous flap (n = 17) and those who underwent primary closure (n = 36). Demographics, clinicopathologic characteristics, and outcomes were compared. The 2 groups were similar in demographics and histopathologic characteristics. Preoperative and surgical factors including comorbidities, nutrition, radiation, surgical times, blood loss, length of stay, and complications were similar between the groups. Of the 17 patients undergoing vertical rectus abdominus myocutaneous flap placement, complications were seen in 11 patients (65%), with most of them stemming from flap dehiscence (n = 7). In our study, the transfer of tissue into the pelvis did not increase surgical times, blood loss, length of stay, or wound complications. Copyright © 2013 Elsevier Inc. All rights reserved.

To explore the reasonable therapeutic strategy for different types of epicanthus. Patients with epicanthus were classificated according to the shape, extent and inner canthal distance and treated with different methods appropriately. Modified asymmetric Z plasty with two curve method was used in lower eyelid type epicanthus, inner canthus type epicanthus and severe upper eyelid type epicanthus. Moderate upper epicanthus underwent '-' shape method. Mild Upper epicanthus in two conditions which underwent nasal augumentation and double eyelid formation with normal inner canthal distance need no correction surgery. The other mild epicanthus underwent '-' shape method. A total of 66 cases underwent the classification and the appropriate treatment. All wounds healed well. During 3 to 12 months follow-up period, all epicanthus were corrected completely with natural contour and unconspicuous scars. All patients were satisfied with the results. Classification of epicanthus hosed on the shape, extent and inner canthal distance and correction with appropriate methods is a reasonable therapeutic strategy.

We clinically investigated 34 patients with obstructive colorectal cancer who underwent placement of a colonic stent as a bridge to surgery(BTS), focusing on endoscopic findings after stent placement.Twenty -nine patients(85.3%)underwent colonoscopy after stent placement, and the entire large intestine could be observed in 28(96.6%).Coexisting lesions were observed in 22(78.6%)of these 28 patients.The lesions comprised adenomatous polyps in 17 patients(60.7%), synchronous colon cancers in 5 patients(17.9%), and obstructive colitis in 3 patients(10.7%), with some overlapping cases.All patients with multiple cancers underwent one-stage surgery, and all lesions were excised at the same time.Colonoscopy after colonic stent placement is important for preoperative diagnosis of coexisting lesions and planning the extent of resection. These considerations support the utility of colonic stenting for BTS.

Some authors have investigated the effects of oxidative stress in some process such as undergoing laparoscopic. However, the effect of upper gastrointestinal system endoscopy process on oxidative stress is unclear. We evaluated the short-term effect of upper gastrointestinal system endoscopy process on oxidative stress. Thirty patients who underwent endoscopy process and 20 healthy controls were enrolled in the prospective study. Serum total antioxidant capacity and total oxidant status measurements were measured before and after endoscopy process. The ratio percentage of total oxidant status to total antioxidant capacity was regarded as oxidative stress index. Before endoscopy process, serum total antioxidant capacity levels were higher, while serum total oxidant status levels and oxidative stress index values were lower in patients than controls, but this difference was not statistically significant (all, p > 0.05). After endoscopy process, serum total antioxidant capacity and total oxidant status levels were significantly higher in patients than before endoscopy process (both, p < 0.05). However, oxidative stress index values were slight higher in patients but this difference was not statistically significant (p > 0.05). We observed that serum TAC and TOS levels were increased in patients who underwent endoscopy process after endoscopy process. However, short-time upper gastrointestinal system endoscopy process did not cause an important change in the oxidative stress index. Further studies enrolling a larger number of patients are required to clarify the results obtained here.

Total maxillectomy is sometimes necessary especially for malignant tumors originating from the maxillary sinus. Here we describe a combined transoral and endoscopic approach for total maxillectomy for the treatment of malignant maxillary sinus tumors and evaluate its short-term outcome. This approach was evaluated in terms of the physiological function, aesthetic outcome, and complications. Six patients underwent the above-mentioned approach for resection of malignant maxillary sinus tumors from May 2010 to June 2011. This combined transoral and endoscopic approach includes five basic steps: total sphenoethmoidectomy, sublabial incision, incision of the frontal process of the maxilla, incision of the zygomaticomaxillary fissure, and hard palate osteotomy. All patients with malignant maxillary sinus tumors successfully underwent the planned total endoscopic maxillectomy without the need for facial incision or transfixion of the nasal septum; there were no significant complications. Five patients received preoperative radiation therapy. All patients were well and had no recurrence at follow-up from 13 to 27 months. The combined approach is feasible and can be performed in carefully selected patients. The benefit of the absence of facial incisions or transfixion of the nasal septum, potential improvement in hemostasis, and visual magnification may help to decrease the morbidity of traditional open approaches.

Enteral access through the jejunum is indicated when patients cannot tolerate oral intake or gastric feeding. While multiple approaches for feeding jejunal access exist, few studies have compared the efficacy of these techniques. The purpose of this study was to investigate the long-term durability, re-intervention rates, and nutritional outcomes following percutaneous endoscopic gastrostomy tubes with jejunal extension tubes (PEG-JET) versus laparoscopic jejunostomy tubes (j-tubes). Retrospective chart review was performed on all patients who underwent PEG-JET or laparoscopic jejunostomy tube placement from January 2005 through December 2015 at our institution. Thirty-day and long-term outcomes were compared between the two groups. A total of 105 patients underwent PEG-JET and 307 patients underwent laparoscopic j-tube placement during the defined study period. In terms of 30-day outcomes, patients who underwent PEG-JET placement were significantly more likely to experience a tube dislodgement event (p = 0.005) and undergo a re-intervention (p < 0.001). Patients who had a laparoscopic j-tube placed were significantly more likely to meet their enteral feeding goals (p = 0.002) and less likely to require nutritional supplementation with total parenteral nutrition (TPN) (p < 0.001). With regard to long-term outcomes, patients who underwent PEG-JET placement were significantly more likely to experience tube occlusion (p < 0.001) and require an endoscopic or surgical tube re-intervention (p < 0.001). Patients who underwent laparoscopic j-tube placement were significantly more likely to experience a tube site leak (p = 0.015) but were less likely to require nutritional supplementation with TPN (p = 0.001). Laparoscopic jejunostomy tubes provide more durable long-term enteral access compared to PEG-JET. Consideration should be given to laparoscopic jejunostomy tube placement in eligible patients who cannot tolerate oral intake or gastric enteral feeding.

The aim of this study was to present a novel approach for complete and permanent ureteral occlusion using a percutaneous injection of Ifabond cyanoacrylate glue. We describe in detail all the steps of our surgery, performed on a 79-year-old patient with urinary leakage from ureteral stump following radical cystectomy. N-hexyl-cyanoacrylate glue (Ifabond) was used to occlude the distal ureter and solve the leakage. Our approach was successful, sparing our already frail patient further surgical procedures. Six months pyelography confirmed the complete ureteral blockage with absence of extravasation. In complicated scenarios with urinary leakages and frail patients, synthetic glues such as Ifabond might represent an interesting therapeutic option to solve the fistulas, leading to durable success with a minimally invasive approach.

A 74 year-old woman developed a polypoid tumor of the bladder which was discovered by hematuria. Upon histological examination, the tumor was shown to be a carcinosarcoma with a weak epithelial composition confirmed by immunolabelling with keratin and was composed essentially of chondrosarcomatous material. Six months later, the patient developed metastases in the kidney, in the paravertebral muscles, and in the right para-ureteral lymph nodes. There are 55 cases of carcinosarcoma of the bladder described in the literature [3, 20, 22]. It is a tumor found more frequently in men than in women, between the ages of 33 to 83. The prognosis is very gloomy .70% death rate within 2 years), but it seems to be improved by radical cystectomy and adjuvant therapy.

A giant ovarian cyst in a neonate.

Soccorso, Giampiero; Walker, Jenny

2009-06-01

Antenatally diagnosed abdominal cysts are common, and frequently are ovarian in origin, which usually regress spontaneously. Surgery is indicated in the infantile period in case of very large, persisting or symptomatic cysts. Many surgeons feel that watchful waiting can be justified in newborns with simple and complex cysts. We present a neonate with an ovarian cyst diagnosed antenatally by ultrasound (US) and showing persistent enlargement within 3 months after birth when reached a diameter of 13 cm. Assessment and treatment is described. The extremely large, non-resolving ovarian cysts in neonates present a major challenge for clinicians and should be treated by surgery to avoid complications. We advocate laparotomy and cystectomy when possible to avoid unnecessary loss of functional ovarian tissue.

This article updates the recently reported intermediate to long-term results with the most commonly used forms of continent cutaneous urinary diversion, and to discuss approaches to early and late complications. Many variations on construction of a continent cutaneous diversion have been described. Results with large series of patients demonstrate acceptable results with all of them, but with a significant revision rate. Long-term complication rates and adaptation to robotic approaches have recently been described. Continent cutaneous diversion is rarely offered in the USA to patients undergoing cystectomy except in a few centers. Most studies have found a high complication rate and need for revision surgery in 10-20% of patients. However, functional results are acceptable and many patients are willing to accept the complications in exchange for avoiding an external appliance.

The safety of laparoscopic management of benign ovarian cysts has been demonstrated. The size of the benign ovarian cyst continues to be a limiting factor for laparoscopic surgery, with most surgeons choosing laparotomy for large cysts. A 15-year-old woman had a 22-cm, benign ovarian cyst extending above the umbilicus that was managed successfully with laparoscopy. We performed prelaparoscopy cyst drainage with a suprapubic Bonanno catheter (Becton Dickinson, Rutherford, New Jersey) followed by laparoscopic cystectomy. Because of its coiled end, the Bonanno catheter is less likely to result in cyst leakage around the aspiration site. With proper patient selection, laparoscopic surgery can be safely applied in a select group of patients with large, benign ovarian cysts.

We present the case of a 52 years old man, with significant familial history, diagnosed with familial adenomatous polyposis-attenuated form, with no clinical and endoscopic surveillance until 2001 when he was admitted for an upper gastrointestinal haemorrhage episode. Upper gastrointestinal scopy revealed duodenal adenomatous polyps and gastric hyperplastic polyps. The patient underwent duodenopancreatectomy with total gastrectomy. The histopathological exam revealed duodenal G2 adenocarcinoma pT3N0, and gastric hyperplastic polyps with no signs of dysplasia. The surgical procedure was followed by chemotherapy. In 2002 the patient was admitted for rectal bleeding and colonoscopy showed 2 sigmoid polyps, appropriate for endoscopic removal and a poly-lobate polyp in the transverse colon. The patient underwent transverse colectomy (the histopathological exam--in situ carcinoma). March 2003--the patient underwent endoscopic removal for a rectal polyp (histopathological exam: moderate dysplasia). In 2005 was noted a pulmonary nodule, located in the postero-apical segment of upper left lobe, for which left superior lobe resection was performed (the histopathological exam: metastatic adenocarcinoma). In May 2006 was performed an exploratory laparotomy. Intraoperatively were noted: peritoneal carcinomatosis and multiple liver metastasis. The surgical procedure recommended in patients with attenuated form of familial adenomatous polyposis and suspect periampullary lesions is duodenopancreatectomy. The particularity of the case is the association of total gastrectomy for gastric hyperplastic polyps.

Objective To determine whether compression ultrasonography or clinical examination should be considered as screening tests for the diagnosis of deep vein thrombosis (DVT) after total hip or knee arthroplasty in patients receiving warfarin prophylaxis postoperatively. Design A prospective cohort study. Setting A single tertiary care orthopedic centre. Patients One hundred and eleven patients who underwent elective total hip or knee arthroplasty were enrolled. Postoperatively the warfarin dose was adjusted daily to maintain the international normalized ratio between 1.8 and 2.5. Eighty-six patients successfully completed the study protocol. Intervention Before they were discharged from hospital, patients were assessed for DVT by clinical examination, bilateral compression ultrasonography of the proximal venous system and bilateral contrast venography. Results DVT was found in 29 patients (34%; 95% confidence interval [CI] 24% to 45%), and 6 patients (7%; 95% CI 3% to 15%) had proximal DVT. DVT developed in 18 (40%) of 45 patients who underwent total knee arthroplasty and in 11 (27%) of 41 patients who underwent total hip arthroplasty. The sensitivity of compression ultrasonography for the diagnosis of proximal DVT was 83% (95% CI 36% to 99%) and the specificity was 98% (95% CI 91% to 99%). The positive predictive value of compression ultrasonography was 71%. In contrast, clinical examination for DVT had a sensitivity of 11% (95% CI 2% to 28%) and a positive predictive value of 25%. Conclusions DVT is a common complication after total hip or knee arthroplasty. Compression ultrasonography appears to be a relatively accurate noninvasive test for diagnosing postoperative proximal DVT. In contrast, clinical examination is a very insensitive test. Whether routine use of screening compression ultrasonography will reduce the morbidity of venous thromboembolism after joint arthroplasty requires confirmation in a prospective trial involving long-term follow-up of patients.

We aimed to evaluate the safety and efficacy of TS-1 adjuvant chemotherapy in Taiwanese patients with gastric cancer. We included in this study patients with locally advanced gastric cancer who received adjuvant TS-1 or 5-fluorouracil chemotherapy after curative surgery and extended lymph node dissection between 1 June 2008 and 31 December 2012 at Chang Gung Memorial Hospital. Patient characteristics, tumor features, safety profiles and compliance with TS-1 treatment were retrospectively analyzed from medical charts. Forty patients received adjuvant chemotherapy with TS-1 and 193 with 5-fluorouracil within the study period. The 1- and 2-year overall survival rates were 90.6% and 87% in the TS-1 group and 95.4% and 86.8% in the 5-fluorouracil group (P = 0.34). The 1- and 2-year disease-free survival rates were 90.6% and 74.7% in the TS-1 group and 88% and 75.7% in the 5-fluorouracil group (P = 0.66). In the TS-1 group, tumor recurrence was more frequent in those with >15 metastatic lymph nodes than ≤15. Overall, 78.9%, 74.3%, 62.1% and 56% of patients underwent TS-1 treatment for at least 3, 6, 9 and 12 months, respectively. The most common adverse events of TS-1 were skin hyperpigmentation (55%), diarrhea (27.5%), dizziness (27.5%) and leucopenia (20%). Severe adverse events (SAEs; grade III or IV toxicity) were diarrhea (7.5%), stomatitis (7.5%), leukopenia (5%), vomiting (2.5%), anorexia (2.5%) and dizziness (2.5%). Patients who underwent total gastrectomy had a significantly greater risk of TS-1-related SAEs than patients who underwent subtotal gastrectomy (40% versus 8%, P = 0.014). The incidence of SAEs during TS-1 therapy was more common in Taiwanese patients with gastric cancer who underwent total gastrectomy compared with those who underwent subtotal gastrectomy. Clinicians must be aware of and able to manage these SAEs to maximize patient compliance with adjuvant TS-1.

ABSTRACT Objectives The aim of this prospective clinical study was to investigate variations in a novel oxidative stress marker (thiol/disulphide homeostasis) in men who underwent transrectal ultrasound guided prostate biopsy (TRUSB). Materials and Methods A total of 22 men undergoing TRUSB of the prostate were enrolled in the study. Patients with abnormal digital rectal examination and/or total prostate specific antigen (PSA) over 4ng/mL underwent TRUSB with 12 cores. Serum samples were obtained before and just after the procedure to evaluate the possible changes in thiol/disulphide homeostasis. Mean age, total PSA and free PSA, prostate volume and histopathological data were also recorded. Results Mean age of the study population was 65.05±8.89 years. Significant decreases in native and total thiol levels were documented after the biopsy procedure. However, serum disulphide levels and disulphide/native thiol, disulphide/total thiol and native/total thiol ratios did not significantly change after TRUSB. No correlation was observed between oxidative parameters and total PSA and free PSA levels, prostate volume and histopathology of the prostate. However, mean patient age was significantly correlated with mean native and total thiol levels. Conclusion Significant decreases in serum native and total thiol levels related to the prostate biopsy procedure suggest that TRUSB causes acute oxidative stress in the human body. Since our trial is the first in the current literature to investigate these oxidative stress markers in urology practice, additional studies are warranted. PMID:28128906

Optimal management of the cervix at the time of hysterectomy and sacrocolpopexy for primary uterovaginal prolapse is unknown. Our hypothesis was that recurrent prolapse at 1 year would be more likely after a supracervical robotic hysterectomy (SRH) compared with a total robotic hysterectomy (TRH) at the time of robotic sacrocolpopexy (RSCP) for uterovaginal prolapse. This was a retrospective cohort analysis of 83 women who underwent hysterectomy with RSCP over a 24-month period (40 with TRH and 43 with SRH). At 1 year post-procedure, subjects completed validated questionnaires regarding pelvic floor symptoms, sexual function, and global satisfaction, and underwent a pelvic examination to identify mesh exposure and evaluate pelvic floor support. Demographics of the two groups were similar, except for a higher mean body mass index in the TRH group (31.9 TRH vs 25.8 SRH kg/m(2), p < 0.001). The rate of recurrent prolapse ≥ stage II was higher for women who underwent SRH compared with TRH (41.9 % vs 20.0 %, p = 0.03; OR 2.8, 95 % CI, 1.07-7.7). However, when this was analyzed as recurrence ≥ hymen, there was no difference between groups (12.5 % TRH vs 18.6 % SRH, p = 0.45). Likewise, there was no difference between groups when a composite measure of success was used (30 out of 40 [75 %] TRH vs 29 out of 43 [67.4 %] SRH, p = 0.45). Women who underwent an SRH were 2.8 times more likely to have a recurrent prolapse, ≥ stage II, at 1 year, compared with those who underwent a TRH, but when composite assessment scores were used there was no difference between the groups.

Defects of maxillofacial skeleton lead to personal (functional and aesthetic), social and behavioral problems; which make the person to isolate from the main stream of society. So, bone regeneration is the need for proper structure, function, and aesthetics following cyst enucleation, trauma, and tumor ablative surgery; which helps for overall health of the individual. The preliminary study is planned to evaluate and compare the efficacy of eggshell-derived hydroxyapatite (EHA) and synthetic hydroxyapatite (SHA) following cystectomy. Microwave-processed calcium deficient EHA and commercially available SHA are used for grafting. Total 20 patients enrolled in this study, consisting 10 in each group between 20 and 45 years of age. All the patients were evaluated for bone regeneration at first, second, third, and sixth month's interval, postsurgically, using radiovisiograph and clinical parameters. The bone formation characteristics vary at second month when compared to SHA. This difference may be because of the kinetics involved in the regeneration pattern. The pattern of bone healing was trabecular after third month, indicating complete bone formation. The study showed constant raise of density and remained same at the end of study period. Both EHA and SHA graft materials are equally efficient in early bone regeneration. Within the limitations of this study the EHA showed promising results. Which indicates the eggshell waste-bio mineral is worthwhile raw material for the production of HA and is a Go Green procedure. Eggshell-derived hydroxyapatite is economic, compared with SHA.

The aim of this study was to compare the effect of antimuscarinic antagonists on carbachol-induced contraction of normal human bladder and detrusor overactivity associated with benign prostatic hyperplasia (DO/BPH). Samples of human bladder muscle were obtained from patients undergoing total cystectomy for bladder cancer (normal bladder), and those undergoing retropubic prostatectomy for BPH. All of the patients with DO/BPH had detrusor overactivity according to urodynamic studies. Detrusor muscle strips were mounted in 10-ml organ baths containing Krebs solution, and concentration-response curves for carbachol were obtained in the presence of antimuscarinic antagonists (4-DAMP, methoctramine, pirenzepine, tolterodine, solifenacin, trospium, propiverine, oxybutynin, and imidafenacin) or vehicle. All antagonists competitively antagonized concentration-response curves to carbachol with high affinities in normal bladder. The rank order of mean pA2 values was as follows: trospium (10.1) > 4-DAMP (9.87), imidafenacin (9.3) > solifenacin (8.8) > tolterodine (8.6) > oxybutynin (8.3) > propiverine (7.7) > pirenzepine (7.4) > methoctramine (6.6). The effects of these antimuscarinic antagonists did not change when tested with DO/BPH bladder, suggesting that each antimuscarinic antagonist has a similar effect in this condition. Schild plots showed a slope corresponding to unity, except for propiverine with DO/BPH detrusor. In conclusion, M3-receptors mainly mediate contractions in human bladder strips with normal state and DO/BPH. Copyright © 2015 The Authors. Production and hosting by Elsevier B.V.

Totally thoracoscopic surgery for the treatment of atrial septal defect without of the robotic Da Vinci surgical system

PubMed Central

2013-01-01

Background More and more surgeons and patients focus on the minimally invasive surgical techniques in the 21st century. Totally thoracoscopic operation provides another minimal invasive surgical option for patients with ASD (atrial septal defect). In this study, we reported our experience of 61 patients with atrial septal defect who underwent totally thoracoscopic operation and discussed the feasibility and safety of the new technique. Methods From January 2010 to October 2012, 61 patients with atrial septal defect underwent totally thoracoscopic closure but not traditional median sternotomy surgery. We divided the 61 patients into two groups based on the operation sequence. The data of group A (the first 30 cases) and group B (the last 31 cases). The mean age of the patients was 35.1 ± 12.8 years (range, 6.3 to 63.5 years), and mean weight was 52.7 ± 11.9 kg (range, 30.5 to 80 kg). Mean size of the atrial septal defect was 16.8 ± 11.3 mm (range, 13 to 39 mm) based on the description of the echocardiography. Results All patients underwent totally thoracoscopy successfully, 36 patients with pericardium patch and 25 patients were sutured directly. 7 patients underwent concomitant tricuspid valvuloplasty with Key technique. No death, reoperation or complete atrioventricular block occurred. The mean time of cardiopulmonary bypass was 68.5 ± 19.1 min (range, 31.0 to 153.0 min), the mean time of aortic cross-clamp was 27.2 ± 11.3 min (range, 0.0 to 80.0 min) and the mean time of operation was 149.8 ± 35.7 min (range, 63.0 to 300.0 min). Postoperative mechanical ventilation averaged 4.9 ± 2.5 hours (range, 3.5 to 12.6 hours), and the duration of intensive care unit stay 20.0 ± 4.8 hours (range, 15.5 to 25 hours). The mean volume of blood drainage was 158 ± 38 ml (range, 51 to 800 ml). No death, residual shunt, lung atelectasis or moderate tricuspid regurgitation was found at 3-month follow-up. Conclusion The totally thoracoscopic operation is feasible and safe for patients with ASD, even with or without tricuspid regurgitation. This technique provides another minimal invasive surgical option for patients with atrial septal defect. PMID:23634811

To evaluate the safety and efficacy of totally laparoscopic total gastrectomy (TLTG) with esophagojejunostomy using a linear stapler compared with laparoscopic-assisted total gastrectomy (LATG) using a circular stapler in gastric cancer patients. We retrospectively reviewed 687 patients who underwent laparoscopic total gastrectomy for gastric cancer at a single institution from August 2008 to August 2014. The patients were divided into two groups according to the type of operation: 421 patients underwent TLTG and 266 underwent LATG. Clinicopathologic characteristics and surgical outcomes in the two groups were compared and analyzed. The TLTG group had higher mean ages at the time of operation (57.78 ± 11.20 years and 55.69 ± 11.96 years, P = 0.020) and more histories of abdominal surgery (20.2% and 12.4%, P = 0.008) compared with the LATG group. Surgical outcomes such as intraoperative and postoperative transfusions, combined operations, pain scores and administration of analgesics, and complications were similar between the two groups. However, compared with the LATG group, the TLTG group required a shorter operation time (149 min vs 170 min, P < 0.001), had lower postoperative hematocrit change (3.49% vs 4.04%, P = 0.002), less intraoperative events (3.1% vs 10.2%, P < 0.001), less intraoperative anastomosis events (2.4% vs 7.1%, P = 0.003), faster postoperative recovery such as median time to first flatus (3.30 d vs 3.60 d, P < 0.001), faster median commencement of soft diet (4.30 d vs 4.60 d, P < 0.001) and shorter length of postoperative hospital stay (6.75 d vs 7.02 d, P = 0.005). The intracorporeal method for reconstruction of esophagojejunostomy using a linear stapler may be considered a feasible procedure comparing with extracorporeal anastomosis using circular stapler because TLTG is simpler and more straightforward than LATG. Therefore, TLTG can be recommended as an appropriate procedure for gastric cancer.

In 2010, the French Haute Autorité de santé (National Health Authority) confirmed the limited value of prostate cancer (PCa) screening by total prostate-specific antigen (PSA) assay. This study was designed to determine the modalities of ordering total PSA or free PSA assays (in the absence of PCa) according to various parameters and the corresponding sums reimbursed. Men aged 40 years and older covered by the national health insurance general scheme (73% of the French population) between 2012 and 2014 were selected. Data were derived from the Système national d'information inter-régimes de l'assurance maladie (Sniiram) (National health insurance information system) database. In 2014, 27% of the 11.6 million men 40 years and older underwent at least one total PSA assay and 5.6% underwent at least one free PSA assay, with marked variations according to the presence or absence of treated lower urinary tract symptoms (LUTS) (53% and 15% vs 24% and 5%) and from one administrative department to another. The peak total PSA assay rate was observed between the ages of 65 and 74 years: 64% of men with LUTS, 46% without LUTS. Between 2012 and 2014, men in whom at least one PSA assay had been performed underwent a mean of 1.8 total PSA assays and 1.7 free PSA assays, with means of 2.3 and 2, respectively, in the presence of LUTS. General practice specialists ordered 91% of the PSA tests reimbursed in 2014 (92% for total PSA and 87% for free PSA) and urologists ordered 4% of reimbursed tests. The total sum reimbursed was €28.5 million, comprising €8.7 million for free PSA. An average of 10 laboratory tests was performed at the same time as the PSA assay in the absence of treated LUTS. Total PSA and free PSA assays are performed in a large number of men, although the value of these tests as first-line test before biopsy remains controversial. These PSA assays are associated with many other laboratory tests looking for possible abnormalities, especially in younger men, and their relevance may therefore not be specifically discussed with the patient.

To determine variations in resource utilization in the management of pediatric acute sinusitis. Retrospective analysis of a publicly available national dataset. The Kids' Inpatient Database 2006 was analyzed using ICD-9 codes for acute sinusitis. A total of 8,381 patients (55% male, mean age 8.5 years [SE = 0.2]) were admitted with acute sinusitis. Mean total charges was $20,062 (SE = 1,159.1). Mean length of stay was 4.2 days (SE = 0.12), with 4.8 diagnoses (SE = 0.06) and 0.85 procedures (SE = 0.06). Thirty-six percent had concomitant respiratory diseases, 11% otitis media, and 8% orbital symptoms. A total of 703 patients underwent operations on the upper aerodigestive tract (534 were nasal sinusectomies); 582 patients underwent lumbar puncture and 162 underwent orbital surgery. The primary payer was private insurance in 50% and Medicaid in 41%. Predictors of increased total charges were male gender (P =.028), being a teaching hospital (P < .0001), metropolitan patient location (P < .0001), hospitals in the western region (P < .0001), admission source from another hospital (P < .0001), and discharge status to another inpatient hospital or home healthcare (P < .0001). There is a large geographic variation in resource utilization (range = $5,837 [Arkansas] to $48,327 [California]). Race, primary payer, admission type, and urgency were not significant predictors of increased resource utilization. Despite being a common diagnosis, there exists a large national variation in management of acute pediatric sinusitis. Predictors of increased resource utilization included male gender, teaching hospital status, metropolitan patient location, western hospital region, admission source, and discharge status. Knowledge of these variables may allow interventions and potentially facilitate benchmarking to reduce the economic burden of this entity while ensuring optimal outcomes.

Learned fear is crucial in the development and maintenance of posttraumatic stress disorder (PTSD) and other anxiety disorders, and extinction of learned fear is necessary for response to exposure-based treatments. In humans, research suggests disrupted sleep impairs consolidation of extinction, though no studies have examined this experimentally using total sleep deprivation. Seventy-one healthy controls underwent a paradigm to acquire conditioned fear to a visual cue. Twenty-four hours after fear conditioning, participants underwent extinction learning. Twenty-four hours after extinction learning, participants underwent extinction recall. Participants were randomized to three groups: 1) well-rested throughout testing ("normal sleep"; n = 21); 2) 36 hours total sleep deprivation before extinction learning ("pre-extinction deprivation"; n = 25); or 3) 36 hours total sleep deprivation after extinction learning and before extinction recall ("post-extinction deprivation"; n = 25). The groups were compared on blink EMG reactivity to the condition stimulus during extinction learning and recall. There were no differences among the three groups during extinction learning. During extinction recall, the pre-extinction deprivation group demonstrated significantly less extinction recall than the normal sleep group. There was no significant difference between the normal sleep and post-extinction deprivation group during extinction recall. Results indicated sleep deprivation prior to extinction training significantly disrupts extinction recall. These findings suggest that (1) sleep deprivation in the immediate aftermath of trauma could be a potential contributor to PTSD development and maintenance via interference with natural extinction processes and (2) management of sleep symptoms should be considered during extinction-based therapy.

To determine the usage of otolaryngology services by children with cleft palate at a pediatric tertiary care facility. Retrospective case series. Specialty clinic at a pediatric tertiary care hospital. Children born between January 1, 1999, and December 31, 2002, with the diagnosis of cleft palate or cleft lip and palate. A total of 41 female and 48 male patients were included. Total number of otolaryngology clinic visits and total number of otolaryngologic surgeries (tympanostomy tube placements and other otologic or upper airway procedures). In the first 5 years of life, these children utilized an average of 8.2 otolaryngology clinic visits (SD = 5.0; range: 1-22) and underwent 3.3 tympanostomy tube surgeries (SD = 2.0; range: 0-10). Seventy-three had their first tube placed at the time of palate repair, and 4 at the time of lip repair. Fifty-one (57.3%) required other otologic or upper airway procedures, including tonsillectomy and/or adenoidectomy (27 children), removal of tympanostomy tubes (24 children), tympanomastoidectomy (3 children), and tympanoplasty (14 children). Of the children who underwent other procedures, they underwent a mean of 1.67 (SD = 0.84; range: 1-4) surgeries. Children with cleft palate are at increased risk for eustachian tube dysfunction, frequently utilize otolaryngology care, and typically receive multiple sets of tympanostomy tubes. This study found that children with cleft palate receive on average of approximately 3 sets of tympanostomy tubes, and the majority required another otologic or upper airway surgery.

We retrospectively studied the surgical treatment for pulmonary metastases from colon and rectal cancer. A total of 24 patients (9 males and 15 females; mean age 61 years) underwent 29 thoracotomies for metastatic colon carcinoma, while 22 patients (16 males and 6 females; mean age 63 years) underwent 29 thoracotomies for metastatic rectal cancer. The median interval between the primary procedure and lung resection for metastases was 26 months in the patients with colon carcinoma and 32 months in the patients with rectal cancer. In the patients with colon carcinoma, 16 underwent wedge resection or segmentectomy (including 4 video-assisted procedures) and 13 (54%) underwent lobectomy or pneumonectomy. In the patients with rectal cancer, 15 underwent wedge or segmentectomy (including 1 video-assisted procedure), 13 (59%) underwent lobectomy or pneumonectomy, and 1 underwent exploratory thoracotomy. All procedures except exploratory thoracotomy were curative operations. There was no mortality. Overall 5-year survival was 56% (n=46). Five-year survival was 65% for patients with colon metastases (n=24) and 45% for patients with rectal metastases (n=22), and there was no significant difference. Recurrent sites were 4 lungs (36%), 4 livers (36%), 1 bone, 1 uterus, and 1 peritoneum in patients with colon carcimoma, and 10 lungs (43%), 5 brains (22%), 3 livers (13%), 1 bone, and 1 vagina in patients with rectal cancer. Pulmonary resection for metastases from colon carcinoma may have better prognosis than that from rectal cancer. However, further investigation may be required to obtain convincing conclusions.

Esophagojejunal anastomosis leakage after total gastrectomy (TG) for esophagogastric junction (EGJ) adenocarcinoma (ADC) constitutes one of the most serious and sometimes life-threatening complications. Management remains controversial and still challenging. A total of 198 patients operated for type I and II EGJ ADC were reviewed. Diagnosis of leakage was based on a combination of clinical and radiological findings. It was classified including objective endoscopic and clinical parameters requiring different type of treatment. Anastomotic leakage was diagnosed in 14 patients (7%). Two cases recovered with conservative therapy. Six cases underwent endoscopy with clips placement in 2 and partially covered self-expandable metal stent placement in 4. Other two cases underwent reoperation with reconstruction of anastomosis and primary repair respectively. In the last four cases emergency surgery with total esophagectomy and diversion was required. Mortality occurred only in 3 of these patients and overall treatment was successful in 11 patients (78.5%). No consensus has been reached on the best method of esophagojejunal anastomosis leakage management and the rate of failure remains significant. Different options of treatment are available but early detection and multidisciplinary approaches are the keys to obtain successful results irrespective of the employed strategy.

The use of a stapler for pharyngeal closure during total laryngectomy was first described in 1971. It provides rapid watertight closure without surgical field contamination. The objective of our study was to compare the incidence of pharyngocutaneous fistula after total laryngectomy with manual and mechanical closures of the pharynx. This was a non-randomised, prospective clinical study conducted at two tertiary medical centres from 1996 to 2011 including consecutive patients with laryngeal tumours who underwent total laryngectomy. We compared the incidence of pharyngocutaneous fistula between two groups of patients: in 20 patients, 75 mm linear stapler closure was applied, whereas in 67 patients a manual suture was used. Clinical data were compared between groups. The groups were statistically similar in terms of gender, age, diabetes mellitus, smoking and alcohol consumption and tumour site. The group of patients who underwent stapler-assisted pharyngeal closure had a higher number of patients with previous tracheotomy (p < 0.001) and previous chemoradiation (p < 0.001). The incidence of pharyngocutaneous fistula was 30% in the mechanical closure group and 20.9% in the manual suture group (p = 0.42). In conclusion the use of the stapler does not increase the rate of fistulae.

Abstract This study aimed to investigate the perioperative analgesic effect of a buprenorphine transdermal patch in patients who underwent simple lumbar discectomy. In total, 96 patients were randomly divided into parecoxib intravenous injection (Group A), oral celecoxib (Group B), and buprenorphine transdermal patch groups (Group C). The pain status, degree of satisfaction, adverse effects, and condition in which the patient received tramadol hydrochloride for uncontrolled pain were recorded on the night before surgery, postoperative day 1, postoperative day 3, and postoperative day 5. The degree of patient satisfaction in Group C was higher than that in Groups A and B, with minimal adverse effects. The buprenorphine transdermal patch had a better perioperative analgesic effect in patients who underwent simple lumbar discectomy. PMID:28514299

Pain following neurosurgery has never been given due attention. This was a prospective study to assess pain following various neurosurgical procedures. Patients underwent pain assessment on 11-point scale(0-10) for 24 hours following neurosurgery, and analyzed in relation to various factors. Among total 159 patients, 88(55%), 58(37%) and 13(8%) had undergone cranial, spinal and peripheral nerve procedures respectively. The mean pain score within 12 hours was 3.51(SD ± 2.53), which increased significantly during 13-24 hours to 5.06(SD ± 2.6)(P<0.001). During 13-24 hours, the pain score among those who underwent infratentorial procedures (8.02 ± 2.77) was significantly higher than among those who underwent supratentorial procedures (3.48 ± 1.99)(P<0.001). The pain score of patients who underwent lumbar surgery (6.5 ± 1.93) was significantly higher than of those who underwent cervical surgery (4.04 ± 2.43)(P<0.001). Age and gender did not show any significant influence on pain. Pain is significantly greater during 13-24 hours after neurosurgery, especially after infratentorial and lumbar surgical procedures, compared to others.

To investigate the surgical strategy of repeated microscopic transsphenoidal surgery (TSS) for treatment of pituitary adenoma, surgical techniques and treatment outcomes for 29 patients with pituitary adenoma were reviewed and analyzed. There were 17 patients who underwent TSS 18 times and 12 patients who underwent TSS 13 times. The interval between each TSS ranged from 3 months to 18 years, with a median time of 4 years. The tumor height was 15 to 45 mm on the last surgery. Among the 29 patients, 16 patients underwent total tumor resection, 11 patients underwent subtotal resection, and 2 patients underwent partial resection. Cerebrospinal fluid leak occurred in 10 patients. Among 24 patients who were followed up effectively, 1 patient developed abducens paralysis after surgery, 1 patient had chronic diabetes insipidus, and 1 patient received steroid-dependent alternative treatment. The repeated TSS may present satisfied outcomes in experienced hands. The upper edge of the posterior choanae should be identified to ensure the right orientation. The openings of the anterior wall of the sphenoid sinus and the sellar floor should be appropriately expanded to improve tumor exposure. The artificial materials should be identified and removed carefully. Intraoperative cerebrospinal fluid leakage should be managed well.

It has been reported that urticaria may be associated with some conditions characterized by sex hormone changes. The case presented concerns a 19-year-old patient who had severe symptoms of chronic urticaria for 3 years, concomitant with an irregular menstrual cycle and functional ovarian cysts. After a laparoscopic ovarian cystectomy the patient was treated with hormonal contraceptives. After 3 weeks the symptoms of urticaria withdrew. The patient continues to receive oral contraceptive treatment, has regular menstruation and shows no symptoms of urticaria. A diagnosis with an urticaria origin should take into consideration any changes in hormone balance as one of the possible reasons for the disease. In such cases, treatment with sex hormones may positively influence the course of the illness.

Laparoscopic management of a fallopian tubal torsion complicated by a large hydrosalpinx

Clinical presentation of an adnexal mass is often non-specific and may mimic a range of gynecological pathology, as well as renal or gastrointestinal causes of lower abdominal pain. While a common entity, its association with a fallopian tube pathology is very uncommon. Imaging such as ultrasound has been diagnostic in the evaluation of a pelvic mass, and has been reported as assisting the diagnosis of fallopian tubal torsion. A pelvic mass of cystic nature can be removed by cystectomy, while treatment options for a torted fallopian tube include surgical detorsion if detected early, or a salpingectomy should there be evidence of necrosis. We report a rare case of fallopian tube torsion complicated by a large hydrosalpinx which was managed by laparoscopic surgery. PMID:22140325

The use of piezosurgery as an alternative method of minimally invasive surgery in the authors’ experience

Piezosurgery is a relatively new technique of bone surgery that is recently gaining popularity in implantology, periodontics and oral surgery. The piezosurgery device produces specific ultrasound frequency modulation (22 000–35 000 Hz). The unit provides extreme precision and safety as well as micrometric cutting, thus allowing one to selectively section the mineralized bone structures. Moreover, the device causes less bleeding during and after the operation and the healing process is shorter. Due to the aforementioned advantages, an ultrasound device could be utilized in a wide range of surgical procedures, e.g. impacted tooth extraction, elevation of the Schneiderian membrane, bone splitting or expansion of the ridge, preparing bone bed and bone sampling, and corticotomy, not to menton cystectomy.

The association between obesity and osteoarthritis is well established, as is the increased risk of postoperative complications after total knee arthroplasty (TKA) and total hip arthroplasty (THA) among patients with obesity. To evaluate the outcomes after TKA/THA based on whether the surgery was performed before or after bariatric surgery. Integrated, multispecialty, community teaching hospital. The medical records of all patients who underwent bariatric surgery from 2001 to 2014 were reviewed. Statistical analysis included χ 2 test and t tests. A P value<.05 was considered significant. One-hundred and two patients were included; 36 had TKA/THA before their bariatric procedure, 66 underwent TKA/THA after their bariatric procedure. TKAs/THAs were performed at a mean of 4.9±3.2 years before and 4.3±3.3 years after bariatric surgery. Body mass index for those undergoing TKA/THA after bariatric surgery was lower than those with TKA/THA before bariatric surgery (37.6±7.4 versus 43.7±5.7 kg/m 2 ; P<.001). Operative time and length of stay (LOS) were significantly decreased for TKA/THA performed after versus before bariatric surgery: 81.7±33.9 min versus 117±38.1 min; P<.001 and 2.9±0.7 versus 3.8±1.4 d; P<.001, respectively. Early complications and late reinterventions were similar. Decreased operative time and LOS were observed among patients who underwent TKA/THA after versus before their bariatric surgery. Patients who underwent TKA/THA after bariatric surgery had lower body mass index before and 1 year after TKA/THA. Postoperative complication rates were similar. Benefits of bariatric surgery and subsequent weight loss should be considered among patients with obesity requiring TKA/THA. Optimal timing of TKA/THA and bariatric surgery has yet to be established.

The optimal extent of gastrectomy for middle-third gastric cancer remains controversial. In our study, the short-term effects and longer-term survival outcomes of distal subtotal gastrectomy and total gastrectomy are analysed to determine the optimal extent of gastrectomy for middle-third gastric cancer. We retrospectively collect and analyse clinicopathologic data and follow-up outcomes from a prospectively collected database at the Peking University Cancer Hospital. Patients with middle-third gastric adenocarcinoma who underwent curative resection are enrolled in our study. We collect data of 339 patients between January 2005 and October 2011. A total of 144 patients underwent distal subtotal gastrectomy, and 195 patients underwent total gastrectomy. Patients in the total gastrectomy group have longer operative duration (P < 0.001) and postoperative hospital stay (P = 0.001) than those in the distal subtotal gastrectomy group. In the total gastrectomy group, more lymph nodes are harvested (P < 0.001). Meanwhile, the rate of postoperative complications is lower in the distal subtotal gastrectomy group than in the total gastrectomy group (8% vs 15%, P = 0.047). Further analysis demonstrates that the rate of anastomosis leakage is lower in the distal subtotal gastrectomy group than in the total gastrectomy group (0% vs 4%, P = 0.023). Kaplan-Meier (log rank test) analysis shows a significant difference in overall survival between the two groups. The 5-year overall survival rates in the distal subtotal gastrectomy and total gastrectomy groups are 65% and 47%, respectively (P < 0.001). Further stage-stratified analysis reveals that no statistical significance exists in 5-year survival rate between the distal subtotal gastrectomy and total gastrectomy groups at the same stage. Multivariate analysis shows that age (P = 0.046), operation duration (P < 0.001), complications (P = 0.037), usage of neoadjuvant chemotherapy (P < 0.001), tumor size (P = 0.012), presence of lymphovascular invasion (P = 0.043) and N stage (P < 0.001) are independent prognostic factors for survival. For patients with middle-third gastric cancer, distal subtotal gastrectomy shortens the operation duration and postoperative hospital stay and reduces postoperative complications. Meanwhile, the long-term survival of patients with distal subtotal gastrectomy is similar to that of those with total gastrectomy at the same stage. The extent of gastrectomy for middle-third gastric cancer is not an independent prognostic factor for survival.

The interrelationship among lymphocytes, macrophages, and neutrophils appears to be an important aspect of the synovial inflammation that is characteristic of rheumatoid arthritis. In a study comparing gold sodium aurothiomalate (GST) with auranofin (Au), an orally absorbed compound, both appeared to inhibit the disease process and no difference between parenteral and oral administration was observed. Another study involved two groups of nine patients with severe rheumatoid arthritis. One group underwent plasmapheresis. The second group underwent total lymphoid irradiation. Both agents appeared to inhibit the disease process. Plasmapheresis was better tolerated that irradiation.

Manipulation under anesthesia (MUA) is performed for knee stiffness following a total knee arthroplasty (TKA) when nonoperative treatments fail. It is important to develop an optimal outpatient physical therapy protocol following an MUA, to avoid a repeat procedure. The purpose of this study was to evaluate and compare: (1) range of motion and (2) the rate of repeat MUA in patients who either underwent innovative multimodal physical therapy (IMMPT) or standard-of-care physical therapy (standard) following an MUA after a TKA. We performed a retrospective database study of patients who underwent an MUA following a TKA between January 2013 to December 2014 ( N  = 57). There were 16 (28%) men and 41 (72%) women who had a mean age of 59 years (range, 32-81 years). The patients were stratified into those who underwent IMMPT ( n  = 22) and those who underwent standard physical therapy ( n  = 35). The 6-month range of motion and rate of repeat manipulation between the two cohorts was analyzed by using Student t-test and Chi-square tests. In addition, we performed a Kaplan-Meier analysis of time to repeat MUA. The IMMPT cohort had a statistically significant higher proportion of TKAs with an optimal range of motion as compared with the standard cohort. There was statistically significant lower proportion of patients who underwent a repeat MUA in the IMMPT as compared with the standard cohort. There was also a significantly lower incidence and longer time to MUA in the IMMPT cohort as compared with the standard cohort in the Kaplan-Meier analysis. The group who underwent IMMPT utilizing Astym therapy had a significantly higher proportion of patients with optimal range of motion, which implies the potential efficacy of this regimen to improve range of motion. Furthermore, the IMMPT cohort had a significantly lower proportion of repeat manipulations as compared with the standard cohort, which implies that an IMMPT approach could potentially reduce the need for a repeat MUA. These findings warrant further investigation into outcomes of different rehab approaches. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

Ascites remains the most common cause of hospitalization among patients with decompensated cirrhosis. Paracentesis is a relatively safe procedure with low complication rates. Computerized tomography (CT)-guided therapeutic paracentesis could be a safe and effective alternative to unaided or aided (ultrasonogram-guided) bedside paracentesis. In this retrospective study, we aimed to compare the efficacy, safety, and cost-effectiveness of CT-guided paracentesis with bedside paracentesis. The period of study was from 2002 to 2012. All patients with cirrhosis who underwent therapeutic paracentesis were included in the study. These patients were divided into two groups. Group I consisted of patients who underwent CT-guided pigtail catheter insertion with ascitic fluid drainage. Group II consisted of patients who underwent beside therapeutic paracentesis after localization of fluid either by physical examination or sonographic localization. We measured the efficacy of CT-guided paracentesis and bedside paracentesis in terms of volume of fluid removed, length of stay, discharge doses of diuretics (spironolactone and furosemide) and number of days to readmission for symptomatic ascites. We also computed the cost-effectiveness of CT-guided therapeutic paracentesis when compared to a bedside procedure. Fischer exact test was used to analyze the distribution of categorical data and unpaired t -test was used for comparison of means. There were a total of 546 unique patients with diagnosed cirrhosis who were admitted to the hospital with symptomatic ascites and underwent therapeutic paracentesis. Two hundred and forty-seven patients underwent CT-guided paracentesis, while 272 patients underwent bedside paracentesis. There was significant inverse correlation between the amount of ascitic fluid removed and total length of stay in the hospital. We found that the volume of fluid removed via a CT-guided pigtail insertion and drainage (2.72 ± 2.02 L) is significantly higher when compared to fluid removed via bedside paracentesis (1.94 ± 1.69). We also found that the interval time period between two successive therapeutic paracenteses was significantly longer for CT group (106.56 ± 75.2 days) when compared to the bedside group (25.57 ± 7.68 days). CT-guided paracentesis with pigtail catheter insertion and drainage is a clinically effective, cheap and safe alternative to conventional bedside paracentesis.

Objectives: There is an increased understanding of hip injury and femoroacetabular impingement (FAI) in elite athlete. Previous evidence suggests that hip pathology accounts for 10% of injuries in football players. The impact of FAI and arthroscopic FAI surgery has not been previously studied for National Football League (NFL) players. The purpose of this study was to investigate the impact of arthroscopic FAI surgery on return to play (RTP) and RTP performance in NFL players. Methods: NFL players undergoing arthroscopic FAI surgery between 2006 and 2014 by two surgeons were identified. Medical records were reviewed for demographic, clinical and operative variables. RTP and RTP performance was assessed based on a review of publically available NFL player statistics. RTP and RTP performance data included time to return to play, games played pre and post season of injury, yearly total yards and touchdowns for offensive players, and yearly total tackles, sacks, and interceptions for defensive players. Offensive power ratings (OPR = [total yards/10] + [total touchdowns × 6]) and defensive power ratings (DPR = total tackles + [total sacks × 2] + [total interceptions × 2]) were calculated for the pre-injury season and the post injury season. Paired t-tests comparing pre and post injury seasons were performed. Results: Forty-eight hips in 40 NFL players were included; eight players underwent bilateral hip arthroscopies. Included players underwent surgery at mean 25.6 years (SD+4.6) and had a mean body mass index of 31.3 (SD+4.6). The majority of players were offensive (N=24; 60%) with the offensive line (N=11; 27.5%) being the most common of all positions. Of the 48 included hips, all had labral tears and 41 (85.4%) underwent labral repair while the remainder had a debridement. Forty-two of the 48 hips (87.5%) underwent CAM decompression, 28 (58.3%) received Subspine decompression and ten (20.8%) underwent rim decompression. The capsule was repaired in 35 of the 48 (72.9%) hip surgeries. Of the 40 included players, 37 (92.5%) achieved RTP after their arthroscopic hip surgeries at mean of 6.0 months. Prior to injury, included patients played in a mean of 11.0 games compared to 9.5 games in their post surgery season (p=0.26). Mean offensive and defensive power ratings (OPR, DPR) demonstrated a non-significant decline in the post surgical season (OPR Pre-injury 40.2, OPR Post-Injury 32.3; p=0.34) (DPR Pre-Injury 49.6, DPR Post-Injury 36.4; p=0.10). There was no significant difference in mean annual salaries based on contracts negotiated pre-injury and the first negotiated contract after surgery (Pre-Injury: $3.3M; Post-Injury: $3.6M; p=0.58) Conclusion: There is a very high rate (92.5%) of return to play in the NFL after arthroscopic FAI surgery; this rate is higher than what has been previously reported for other orthopaedic procedures. Additionally, NFL players are able to achieve a return to sport at a faster time frame (6 months) than previously reported for other procedures. There does appear to be a non-significant decline in both offensive and defensive performance with defensive performance experiencing a greater magnitude of decline. It is unclear whether the decreased on-field statistics are attributable to the surgical procedure or an expected age related decline in performance. Undergoing surgery does not appear to have a financial impact however. These findings have important implications for counseling elite athletes about the expected impact of arthroscopic FAI surgery.

Symptoms of severe nausea, vomiting, abdominal pain, and frequent bezoars, as well as objective gastric retention, can occur following Roux-Y biliary diversion for alkaline reflux gastritis. Medical therapy and prokinetic drugs have proven ineffective. This review evaluates 37 patients who underwent further gastric resection from 1979 to 1987 to improve gastric emptying and resolve symptoms. Fifteen patients underwent perioperative radionuclide solid-food gastric emptying studies. Seventy-three per cent (27 of 37 patients) of the patients who underwent further gastric resection (70% to 95%) had a satisfactory postoperative response. Twenty patients were graded Visick 1 or 2 and 7 Visick-3 patients, althoughmore » much improved, still had some symptoms of gastroparesis. Twenty-seven per cent (10 of 37 patients) failed to improve and underwent completion total gastrectomy. Overall, 70% of this group had almost complete resolution of their symptoms. Three of 10 patients were considered ''failures'' due to postprandial pain in 1 and early vasomotor dumping in 2. Of the 10 patients who failed initial revisional surgery, 7 underwent a 70% to 80% subtotal gastric resection (STG) and 3 patients underwent 85% to 95% extensive resection (EXT.G.). Of the 15 patients who underwent perioperative radionuclide evaluation, a mean two-hour gastric retention of 61.4% +/- 4% (SEM) decreased to 25% +/- 4% following further gastric resection. Eight patients were in the STG group and seven patients were in the EXT.G group. Following STG, mean two-hour gastric retention of 58.2% +/- 3.5% decreased to 38% +/- 3% (p less than 0.05). In seven patients who underwent EXT.G, mean two-hour retention of 65% +/- 4% decreased to 10% +/- 2.5% (p less than 0.005). EXT.G resulted in normal gastric emptying and few late failures.« less

The thyroid gland is removed en bloc during laryngectomy. There are no objective criteria for deciding the extent of thyroid gland resection in primary hypopharyngeal cancer cases. The present study aimed to determine the incidence of thyroid gland involvement in hypopharyngeal cancer and identify the various predictors of this involvement. This paper reports a retrospective analysis of 358 patients with hypopharyngeal cancer, who underwent total laryngectomy with partial or total pharyngectomy at Tata Memorial Hospital, Mumbai between 2004 and 2010. The mean age of this population was 61 years. The pyriform sinus was the most common hypopharyngeal subsite involved (in 89 per cent of cases). Most patients underwent hemi-thyroidectomy as part of their surgery. The thyroid gland was involved in only 13 per cent of cases. Thyroid gland involvement is not common in hypopharyngeal cancer. Cases that involved the post-cricoid area, subglottic extension, extralaryngeal spread or prior tracheostomy were associated with a higher risk of thyroid gland involvement. Ipsilateral thyroidectomy is sufficient in most patients undergoing surgery (laryngectomy with partial or total pharyngectomy) for hypopharyngeal cancers.

To evaluate lenticular oxidative stress in rat menopausal models. Forty Wistar female albino rats were included in this study. A total of thirty rats underwent oophorectomy to generate a menopausal model. Ten rats that did not undergo oophorectomy formed the control group (Group 1). From the rats that underwent oophorectomy, 10 formed the menopause control group (Group 2), 10 were administered a daily injection of methylprednisolone until the end of the study (Group 3), and the remaining 10 rats were administered intraperitoneal streptozocin to induce diabetes mellitus (Group 4). Total oxidant status (TOS), total antioxidant capacity (TAC), and oxidative stress index (OSI) measurements of the crystalline lenses were analyzed. The mean OSI was the lowest in group 1 and highest in group 4. Nevertheless, the difference between the groups was not statistically significant in terms of OSI (p >0.05). The mean TOS values were similar between the groups (p >0.05), whereas the mean TAC of group 1 was significantly higher than that of the other groups (p <0.001). Our results indicate that menopause may not promote cataract formation.

Introduction: We assess the practice patterns of artificial urinary sphincter (AUS) and urethral sling insertion after radical prostatectomy (RP) from a large population-based cohort. Methods: We examined 25 346 men in Ontario, Canada who underwent RP between 1993 and 2006. Using hospital and cancer registry data, we identified patients who subsequently underwent an incontinence procedure. We characterized the practice patterns of post-prostatectomy incontinence procedures across Ontario during the study interval. Results: A total of 703 (2.8%) men underwent subsequent insertion of an AUS and 282 (1.1%) underwent a urethral sling procedure (985 total incontinence procedures, 3.9%) over the study period. During the study period, 121 hospitals performed RP. Among them, 32 (26%) hospitals performed both RP and AUS/sling procedures, and 89 (74%) performed RP only. Four hospitals performed AUS/sling procedures but not RP. Of the 36 institutions that performed AUS/sling procedures, the median annual case volume was 0.29 (interquartile range: 0.083-0.75). Of all incontinence procedures, 56% were performed at 3 academic institutions. When examining observed rates of AUS/sling procedures compared with expected rates from the overall cohort, 15 of 32 hospitals (47%) performed significantly fewer incontinence procedures than expected given their RP case volume (p range: <0.0001–0.0390) and 5 (16%) performed significantly more (p range: <0.0001–0.038). Conclusions: A small number of academic institutions provide most of the surgical care for men with incontinence following RP in Ontario. Many centres that perform RP refer out to other centres to surgically manage their patients’ incontinence. PMID:25408805

Background High-resolution manometry (HRM) has improved the accuracy of manometry in detecting achalasia and has helped distinguish between clinically relevant subtypes. This study investigated whether HRM metrics correlate with the achalasia symptoms and symptomatic outcomes of peroral esophageal myotomy (POEM). Methods Of the 30 patients who were enrolled, 25 were treated with POEM, 12 of who underwent HRM after 3 months. All the patients completed the Eckardt score questionnaires, and those who underwent POEM were followed up for about 6 months. Pearson correlation was used to assess the relationship between the HRM metrics and symptoms and outcomes. Key results The integrated relaxation pressure (IRP) score positively correlated with the total Eckardt score, regurgitation score and weight loss score in all the patients, and with the weight loss score in type I achalasia. In 25 patients (10 patients, type I; 15 patients, type II) who underwent POEM, the total Eckardt scores and individual symptom scores significantly decreased after surgery. Changes in the Eckardt scores were similar between type I and type II. Further, the Eckardt scores and weight loss score changes were positively correlated with baseline IRP. Twelve patients (4 patients, type I; 8 patients, type II) underwent HRM again after POEM. IRP changed significantly after POEM, as did the DEP in type II. The IRP changes after POEM were positively correlated with the Eckardt score changes. Conclusions & Inferences IRP is correlated with the symptoms and outcomes of achalasia patients. Thus, HRM is effective for assessing the severity of achalasia and can predict the efficacy of POEM. PMID:26421919

We determined the risk of arteriovenous fistula after en bloc ligation of the renal hilum. A prospective evaluation of all patients who underwent en bloc ligation of the renal hilum during nephrectomy for malignant disease was performed. Pertinent operative data were recorded and patients were followed for clinical evidence of arteriovenous fistula formation, including hypertension, abdominal bruit and new onset congestive heart failure. Patients with at least 12 months of followup underwent computerized tomographic arteriography to assess arteriovenous fistula formation. A total of 94 patients underwent en bloc renal hilar ligation during open (43) and laparoscopic (51) nephrectomy using a 45 mm titanium endovascular stapler. Of this cohort 11 patients were lost to followup and 3 died of disease. The remaining 80 patients were followed an average of 35.2 months with no clinical evidence of arteriovenous fistula formation. Specifically there was no statistically significant difference in preoperative and postoperative blood pressure (p = 0.18 and 0.62, respectively), no evidence of abdominal bruit on examination and no new onset congestive heart failure. A total of 32 had increased serum creatinine and, therefore, they were excluded from followup computerized tomographic arteriography. Eight patients had a followup of less than 1 year and they were not yet eligible for evaluation. In the 40 patients who underwent computerized tomographic arteriography no fistulas were noted. Based on clinical followup and prospective radiographic evaluation there appears to be a low risk of arteriovenous fistula formation after en bloc ligation of the renal hilum using a titanium endovascular stapler.

Bladder urothelial carcinoma has high rates of mortality and morbidity. Identifying novel molecular prognostic factors and targets of therapy is crucial. Mammalian target of rapamycin (mTOR) pathway plays a pivotal role in establishing cell shape, migration, and proliferation. Tissue microarrays were constructed from 132 cystectomies (1994-2002). Immunohistochemistry was performed for Pten, c-myc, p27, phosphorylated (phos)Akt, phosS6, and 4E-BP1. Markers were evaluated for pattern, percentage, and intensity of staining. Mean length of follow-up was 62.6 months (range, 1-182 months). Disease progression, overall survival (OS), and disease-specific survival (DSS) rates were 42%, 60%, and 68%, respectively. Pten showed loss of expression in 35% of bladder urothelial carcinoma. All markers showed lower expression in invasive bladder urothelial carcinoma compared with benign urothelium with the exception of 4E-BP1. Pten, p27, phosAkt, phosS6, and 4E-BP1 expression correlated with pathologic stage (pathological stage; P<.03). Pten, 4E-BP1, and phosAkt expression correlated with divergent aggressive histology and invasion. phosS6 expression inversely predicted OS (P=.01), DSS (P=.001), and progression (P=.05). c-myc expression inversely predicted progression (P=.01). In a multivariate analysis model that included TNM stage grouping, divergent aggressive histology, concomitant carcinoma in situ, phosS6, and c-myc expression, phosS6 was an independent predictor of DSS (P=.03; hazard ratio [HR], -0.19), whereas c-myc was an independent predictor of progression (P=.02; HR, -0.38). In a second model substituting organ-confined disease and lymph node status for TNM stage grouping, phosS6 and c-myc remained independent predictors of DSS (P=.03; HR, -0.21) and progression (P=.03; HR, -0.34), respectively. We found an overall down-regulation of mTOR pathway in bladder urothelial carcinoma. phosS6 independently predicted DSS, and c-myc independently predicted progression.

Functional outcomes after ileal bladder substitution reflect the expectations of future patients at a particular centre. The aim of this study was to use validated questionnaires and a pad-weighing test to investigate functional outcomes after neobladder reconstruction at long-term follow-up in patients at a single centre. During 2005 - 2015, 75 patients received a Studer ileal bladder substitute at the Department of Urology, Malmö. Forty-six of these patients were alive for follow-up and were evaluated using the pad-weighing test and the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI-SF), the Female Sexual Function Index (FSFI) and the International Index of Erectile Function (IIEF). Five of 37 evaluable patients (14%) were considered fully continent, reporting a pad-weighing test result of 0 g and an ICIQ-UI-SF score of 0. The median ICIQ-UI-SF score was 8 [interquartile range (IQR) 3-11], and seven patients (17%) were continent according to the ICIQ-UI-SF score only. In the pad-weighing test, 28 out of 37 patients (76%) reported 0 g day-time leakage whereas only 12 out of 37 patients (32%) reported 0 g night-time leakage. At follow-up, nine out of 39 (23%) of evaluable male patients were potent. The median ICIQ-UI-SF score was significantly lower during the second half of the study period [4 (IQR 0-8) vs 10 (IQR 6-14); p = .003]. The inverse applied to the median IIEF score [5 (IQR 3-12) vs 2 (IQR 1-4); p = .02]. Functional outcomes at long-term follow-up after radical cystectomy and Studer ileal bladder substitute were at best modest in this series. Better outcomes during the second half of the study period might be explained by improved patient selection and a refined surgical technique, but possibly also by longer follow-up of patients during the first half of the period resulting in a more pronounced time-dependent decline in functional outcomes.

Neoadjuvant chemotherapy in pure urothelial bladder cancer provides a significant survival benefit. However, to the authors' knowledge, it is unknown whether this benefit persists in histological variants. The objective of the current study was to assess the effect of neoadjuvant chemotherapy on the probability of non-organ-confined disease and overall survival after radical cystectomy (RC) in patients with histological variants. Querying the National Cancer Data Base, the authors identified 2018 patients with histological variants who were undergoing RC for bladder cancer between 2003 and 2012. Variants were categorized as micropapillary or sarcomatoid differentiation, squamous cell carcinoma, adenocarcinoma, neuroendocrine tumors, and other histology. Logistic regression models estimated the odds of non-organ-confined disease at the time of RC for each histological variant, stratified by the receipt of neoadjuvant chemotherapy. Cox regression models were used to examine the effect of neoadjuvant chemotherapy on overall mortality in each variant subgroup. Patients with neuroendocrine tumors (odds ratio [OR], 0.16; 95% confidence interval [95% CI], 0.08-0.32 [P<.001]), micropapillary differentiation (OR, 0.30; 95% CI, 0.10-0.95 [P=.041]), sarcomatoid urothelial carcinoma (OR, 0.40; 95% CI, 0.17-0.94 [P=.035]), and adenocarcinoma (OR, 0.24; 95% CI, 0.06-0.91 [P=.035]) were less likely to harbor non-organ-confined disease at the time of RC when treated with neoadjuvant chemotherapy. An overall survival benefit for neoadjuvant chemotherapy was only found in patients with neuroendocrine tumors (hazard ratio, 0.49; 95% CI, 0.33-0.74 [P=.001]). Patients with neuroendocrine tumors benefit from neoadjuvant chemotherapy, as evidenced by better overall survival and lower rates of non-organ-confined disease at the time of RC. For tumors with micropapillary differentiation, sarcomatoid differentiation, or adenocarcinoma, neoadjuvant chemotherapy decreased the frequency of non-organ-confined disease at the time of RC. However, this favorable effect did not translate into a statistically significant overall survival benefit for these patients, potentially due to the aggressive tumor biology.

Patients with aggressive urothelial cell carcinoma (UCC) that undergo radical cystectomy or nephroureterectomy exhibit markedly high rates of disease recurrence and mortality. To select appropriate adjuvant thxerapies in addition to radical surgery, the identification of predictive prognostic markers for UCC patients is required. The aim of the present study was to identify such markers, by evaluating the association of UCC complement component 5 (C5) fragment a (C5a)receptor (C5aR) expression, detected using immunohistochemistry, with clinicopathological parameters and survival outcomes of UCC patients. The results revealed that C5aR was expressed in cancer cells, particularly at the invasive front, but not in noncancerous urothelial cells or adjacent cells. The UCC C5aR-positive rate of patients treated with radical surgeries was 73% (38/52) and the rate was 83% (20/24) at stages I-II of disease. No correlation between C5aR expression and any of clinicopathological parameters, which included gender, tumor location, World Health Organization grade, T stage, vessel invasion and stage of disease, was identified. However, univariate and multivariate analyses revealed that C5aR-positive UCC patients exhibited significantly lower overall survival rates [hazard ratio (HR), 3.14; 95% confidence interval (CI), 1.03-9.60; P=0.035 and HR, 3.92; 95% CI, 1.15-13.4; P=0.029, respectively] and 5-year survival rates (0.42 vs. 0.83) compared with C5aR-negative UCC patients. Furthermore, 5-year survival and disease-specific survival rates were lower in patients with C5aR-positive UCC (0.51; 95% CI, 0.30-0.71) than patients with C5aR-negative UCC (0.83; 95% CI, 0.62-1.00). These results indicate that UCC C5aR expression is predictive of poor patient outcomes and thus may lead to the appropriate selection of adjuvant therapies at earlier UCC stages, which could improve patient prognosis.

Baumann, Brian C.; Guzzo, Thomas J.; He Jiwei

2013-01-01

Purpose: Local-regional failures (LF) following radical cystectomy (RC) plus pelvic lymph node dissection (PLND) with or without chemotherapy for invasive urothelial bladder carcinoma are more common than previously reported. Adjuvant radiation therapy (RT) could reduce LF but currently has no defined role because of previously reported morbidity. Modern techniques with improved normal tissue sparing have rekindled interest in RT. We assessed the risk of LF and determined those factors that predict recurrence to facilitate patient selection for future adjuvant RT trials. Methods and Materials: From 1990-2008, 442 patients with urothelial bladder carcinoma at University of Pennsylvania were prospectively followed aftermore » RC plus PLND with or without chemotherapy with routine pelvic computed tomography (CT) or magnetic resonance imaging (MRI). One hundred thirty (29%) patients received chemotherapy. LF was any pelvic failure detected before or within 3 months of distant failure. Competing risk analyses identified factors predicting increased LF risk. Results: On univariate analysis, pathologic stage {>=}pT3, <10 nodes removed, positive margins, positive nodes, hydronephrosis, lymphovascular invasion, and mixed histology significantly predicted LF; node density was marginally predictive, but use of chemotherapy, number of positive nodes, type of surgical diversion, age, gender, race, smoking history, and body mass index were not. On multivariate analysis, only stage {>=}pT3 and <10 nodes removed were significant independent LF predictors with hazard ratios of 3.17 and 2.37, respectively (P<.01). Analysis identified 3 patient subgroups with significantly different LF risks: low-risk ({<=}pT2), intermediate-risk ({>=}pT3 and {>=}10 nodes removed), and high-risk ({>=}pT3 and <10 nodes) with 5-year LF rates of 8%, 23%, and 42%, respectively (P<.01). Conclusions: This series using routine CT and MRI surveillance to detect LF confirms that such failures are relatively common in cases of locally advanced disease and provides a rubric based on pathological stage and number of nodes removed that stratifies patients into 3 groups with significantly different LF risks to simplify patient selection for future adjuvant radiation therapy trials.« less

The aim of this study was to investigate the pancreas anatomy and surgical procedure for harvesting pancreas for islet isolation while performing pancreatectomy to induce diabetes in rhesus monkeys. The necropsy was performed in three cadaveric monkeys. Two monkeys underwent the total pancreatectomy and four underwent partial pancreatectomy (70-75%). The greater omentum without ligament to transverse colon, the cystic artery arising from the proper hepatic artery and the branches supplying the paries posterior gastricus from the splenic artery were observed. For pancreatectomy, resected pancreas can be used for islet isolation. Diabetes was not induced in the monkeys undergoing partial pancreatectomy (70-75%). Pancreas anatomy in rhesus monkeys is not the same as in human. Diabetes can be induced in rhesus monkeys by total but not partial pancreatectomy (70-75%). Resected pancreas can be used for islet isolation while performing pancreatectomy to induce diabetes. © 2011 John Wiley & Sons A/S.

This study aims to evaluate component alignment in a large cohort of total knee arthroplasties (TKAs) and ascertain whether alignment in TKAs undergoing postoperative manipulation under anesthetic is significantly different from those achieving good function. A retrospective review of 281 consecutive primary TKAs was performed. All TKAs underwent computed tomographic scanning (Perth computed tomography knee protocol). Of 281 TKAs, 21 (7.4%) underwent manipulation, performed at a mean of 8.1 weeks (range, 3-14 weeks) after surgery. No statistically significant difference was seen between groups for any of 12 parameters of alignment. Postoperative stiffness with the need for manipulation under anesthetic is multifactorial in origin. This study found insufficient evidence to support the theory that component alignment contributes significantly to the etiology of this difficult problem. Crown Copyright © 2013.

The objective of this study was to delineate the long-term results of surgical treatment of pediatric low-grade cerebellar astrocytoma. One hundred consecutive children and adolescents (0-19 years old) who underwent primary tumor resection for a low-grade cerebellar astrocytoma during the years 1980-2011 were included in this retrospective study on surgical morbidity, mortality rate, academic achievement, and/or work participation. Gross motor function and activities of daily living were scored according to the Barthel Index. Of the 100 patients, 61 children were in the 1st decade, and 39 were 10-19 years old. The male/female ratio was 1.13:1 (53 males, 47 females). No patients were lost to follow-up. There were no deaths in this series and all 100 patients are currently alive. In 29 patients, the follow-up duration was less than 10 years, in 37 it was between 10 and 19 years, and in 34 it was between 20 and 31 years. The Barthel Index was 100 (normal) in 97 patients, 90 in 2 patients, and 40 in the last patient. A total of 113 tumor resections were performed. Two patients underwent further tumor resection due to MRI-confirmed residual tumor demonstrated on the immediate postoperative MR image (obtained the day after the initial procedure). Furthermore, 9 children underwent repeat tumor resection after MRI-confirmed progressive tumor recurrence up to 10 years after the initial operation. Two of these patients also underwent a third resection, without subsequent radiation therapy, and have experienced 8 and 12 years of tumor-free follow-up thereafter, respectively. A total of 15% of the patients required treatment for persistent hydrocephalus. Low-grade cerebellar astrocytoma is a surgical disease, in need of long-term follow-up, but with excellent long-term results. Nine percent of the children in this study underwent repeated surgery due to progressive tumor recurrence, and 15% were treated for persistent hydrocephalus.

To evaluate the prognostic value of the depth of lamina propria invasion in patients with T1 bladder cancer and to display comparative differences between the T1a/b and T1e/m substaging systems. This study included 106 patients with primary stage T1 urothelial bladder tumours who underwent surgery between January 2009 and December 2014. Pathologic specimens were re-evaluated to confirm the diagnosis of T1 and substaging by the same pathologist using two systems: T1a and T1b, and T1m and T1e. Age, tumour size, multiplicity, associated carcinoma in situ, tumour grade, and T1 substaging system were investigated to detect the relation between disease progression and recurrence. The recurrence rate was 52% for T1a (n=42) vs. 76% for T1b (n=20) (p=0.028) and 55% for T1m (n=32) vs. 62% for T1e (n=30), respectively (p=0.446). There was no significant difference between the substaging groups for disease progression: T1a (n=12, 15%) vs. T1b (n=7, 27%), and T1m (n=8, 13.8%) vs. T1e (n=11, 23%) (p>0.05). In the multivariate analysis, tumour size >3 cm (p=0.008), multiplicity (p=0.049), and substaging T1b (p=0.043) were independent predictive factors for tumour recurrence. According to the Kaplan-Meier actuarial method, recurrence-free survival was significantly different in patients with pT1a tumours compared with those with pT1b tumours (p=0.033). Substaging T1 provides a prediction of disease recurrence. Regarding recurrence, T1a/b substaging can provide better knowledge of disease behaviour because it is predicted as more superior than T1 m/e, and it can help in determining the requirement for early cystectomy.

The purpose of this retrospective study was to assess complications, voiding patterns, and quality of life in patients with an orthotopic bladder substitution, using an N-shaped ileal neobladder. Between May 1996 and December 2002, 58 patients (52 men and 6 women) underwent an orthotopic ileal neobladder reconstruction after radical cystectomy. The mean age was 47 for the female and 60 for the male patients. In all patients an N-shaped ileal pouch was constructed. This pouch has not yet been described in the literature before. All procedures were performed by the same surgeon (HVP) and the mean follow-up was 38 months. Complications were registered as early (occurring within 3 months) or late (occurring after 3 months), and as pouch-related and non-pouch-related. The patients took part in a pelvic floor re-education programme for as long as they were incontinent. All patients completed a retrospective Quality of Life questionnaire, based on the QLQ-C30 questionnaire, which was validated by the EORTC's Study Group on Quality of Life. In 38% of the patients, early complications occurred, whereas 48% had late complications. The most frequent early complications were diarrhea (24%) and pyelonephritis (9%). Diarrhea was again the most frequently mentioned non-pouch-related complication (19%). The most frequently observed pouch-related late complication was ileo-urethral stenosis. This occurred in five patients. All of these 5 patients were re-operated using a minimally invasive approach. Daytime continence was achieved in 95% of patients and nighttime continence in 66%. Hyper-continence with subsequent need for CISC was observed in 5 out of 6 women (83%) and 0 out of 52 men (0%). The retrospective QoL questionnaire learned that the impact of bladder removal and orthotopic bladder substitution has acceptable impact on patient's everyday life. Diarrhea was mentioned as being the most discomforting complication by most of the patients. We describe a modified orthotopic ileal neobladder: the ileal N-pouch. The functional results with this pouch are good. Complication rates and QoL are comparable with the larger series published by other authors, using different ileal neobladder reconstructions.

Both Total and Subtotal Thyroidectomy are correct treatment options for symptomatic Euthyroid Multinodular Goitre. The choice depends upon surgeon's preference due to consideration of disadvantages like permanent hypothyroidism in Total Thyroidectomy and high chances of recurrence in Subtotal Thyroidectomy. Many surgeons believe that there is a higher incidence of Recurrent Laryngeal nerve injury in Total Thyroidectomy which affects their choice of surgery. This study aimed to compare the incidence of recurrent laryngeal nerve injury in total versus subtotal thyroidectomy. This non randomized controlled trial was carried out at Department of Surgery and ENT of Ayub Teaching Hospital Abbottabad, and Combined Military Hospital Rawalpindi from 1st September 2013 to 30th August 2014. During the period of study, patients presenting in surgical outpatient department with euthyroid multinodular goitre having pressure symptoms requiring thyroidectomy were divided into two groups by convenience sampling with 87 patients in group 1 and 90 patients in group 2. Group-1 was subjected to total thyroidectomy and Group -2 underwent subtotal thyroidectomy. All the patients had preoperative Indirect Laryngoscopy examination and it was repeated postoperatively to check for injury to the recurrent laryngeal nerve. A total of 177 patients were included in the study. Out of these, 87 patients underwent total thyroidectomy (Group-1). Two of these patients developed recurrent laryngeal nerve injury (2.3%). In group-2 subjected to subtotal thyroidectomy, three of the patients developed recurrent laryngeal nerve injury (3.3%). The p-value was 0.678. The overall risk of injury to this nerve in both surgeries combined was 2.8%. There is no significant difference in the risk of recurrent laryngeal nerve damage in patients undergoing total versus subtotal thyroidectomy.

Patients with depression and other psychiatric disorders being considered for electroconvulsive therapy (ECT) may also have asthma. Since ECT requires the administration of general anaesthesia, it is assumed that extra care should be taken with asthmatic patients before and during ECT. We sought to investigate the safety of ECT in asthmatic patients. A retrospective review was conducted of the medical records of all of the patients with currently active and managed asthma who underwent ECT for severe depressive syndromes at Mayo Clinic, Rochester, Minnesota, between 1 January 1998, and 30 June 2006. Thirty-four patients with asthma who also underwent ECT were identified. Of these, 27 (79%) were women. The median age was 45 years (range 23-84 years). All 34 patients were using asthma medications daily at the time of ECT. The 34 patients underwent a total of 459 ECT sessions. Four (12%) patients experienced exacerbation of their asthma on a total of five occasions. Each exacerbation was successfully treated with standard asthma medications, and all four patients completed their courses of ECT. ECT in patients with asthma appears to be safe. Although exacerbation of asthma after ECT was rare in our series, a prospective study would be needed to determine the precise risk of pulmonary complications of ECT in asthmatic patients.

[Purpose] We aimed to examine the effectiveness of a community-based virtual reality treadmill training (CVRTT) program on static balance abilities in patients with stroke. [Subjects and Methods] Patients (n = 20) who suffered a stroke at least 6 months prior to the study were recruited. All subjects underwent conventional physical therapy for 60 min/day, 5 days/week, for 4 weeks. Additionally, the CVRTT group underwent community-based virtual reality scene exposure combined with treadmill training for 30 min/day, 3 days/week, for 4 weeks, whereas the control group underwent conventional physical therapy, including muscle strengthening, balance training, and indoor and outdoor gait training, for 30 min/day, 3 days/week, for 4 weeks. Outcome measurements included the anteroposterior, mediolateral, and total postural sway path lengths and speed, which were recorded using the Balancia Software on a Wii Fit(™) balance board. [Results] The postural sway speed and anteroposterior and total postural sway path lengths were significantly decreased in the CVRTT group. Overall, the CVRTT group showed significantly greater improvement than the control group. [Conclusions] The present study results can be used to support the use of CVRTT for effectively improving balance in stroke patients. Moreover, we determined that a CVRTT program for stroke patients is both feasible and suitable.

While the outcomes after Heller myotomy have been extensively reported, little is known about patients with esophageal achalasia who are treated with esophagectomy. This was a retrospective analysis using the Nationwide Inpatient Sample over an 11-year period (2000-2010). Patients admitted with a primary diagnosis of achalasia who underwent esophagectomy (group 1) were compared to patients with esophageal cancer who underwent esophagectomy (group 2) during the same time period. Primary outcome was in-hospital mortality. Secondary outcomes included length of stay, postoperative complications, and total hospital charges. A propensity-matched analysis was conducted comparing the same outcomes between group 1 and well-matched controls in group 2. Nine hundred sixty-three patients with achalasia and 18,003 patients with esophageal cancer underwent esophagectomy. The propensity matched analysis showed a trend toward a higher mortality in group 2 (7.8 vs. 2.9 %, p = 0.08). Postoperative length of stay and complications were similar in both groups. Total hospital charges were higher for the achalasia group ($115,087 vs. $99, 654.2, p = 0.006). This is the largest study to date examining outcomes after esophagectomy in patients with achalasia. Based on our findings, esophagectomy can be considered a safe option, and surgeons should not be hindered by a perceived notion of prohibitive operative risk in this patient population.

Previous studies have shown a high incidence of cardiovascular complications when noncardiac surgery (NCS) is performed after coronary stenting. No study has compared the outcomes of NCS after stenting compared with percutaneous transluminal coronary angioplasty (PTCA) alone. The records of all patients who underwent NCS within 3 months of percutaneous coronary intervention at our institution were reviewed for adverse clinical events with the end points of acute myocardial infarction, major bleeding, and death < or = 6 months after NCS. A total of 216 consecutive patients were included in the study. Of these, 122 (56%) underwent PTCA and 94 (44%) underwent stenting. A total of 26 patients (12%) died, 13 in the stent group (14%) and 13 in the PTCA group (11%), a nonsignificant difference. The incidence of acute myocardial infarction and major bleeding was 7% and 16% in the stent group and 6% and 13% in the PTCA group (p = NS), respectively. Significantly more events occurred in the 2 groups when NCS was performed within 2 weeks of percutaneous coronary intervention. In conclusion, our study has demonstrated high rates of perioperative morbidity and mortality after NCS in patients undergoing PTCA alone, as well as stenting. These findings support the current guidelines regarding the risk of NCS after stenting but suggest they be extended to PTCA as well.

To evaluate the surgical diagnosis and treatment of primary hyperthyroidism complicated with occult thyroid carcinoma. Data of 51 cases of primary hyperthyroidism complicated with occult thyroid carcinoma admitted during January 2004 to November 2014 were analyzed retrospectively. The incidence of occult thyroid carcinoma was 5.03% in hyperthyroidism,and 47 cases (92.16%) were female. The preoperative diagnosis of all these 51 cases was primary hyperthyroidism and 11 cases were diagnosed thyroid carcinoma at the same time;25 cases were diagnosed thyroid carcinoma by frozen section and the remaining 26 cases were diagnosed by postoperative pathology. Finally,26 cases underwent subtotal thyroidectomy,4 cases underwent total thyroidectomy, and 21 cases underwent total thyroidectomy with lymphadenectomy. The tumor size ranged from 0.1 to 1.0 cm [mean:(0.63 ± 0.35) cm]. The lesions were less than or equal to 0.5 cm in 28 cases (54.9%). The follow-up lasted from 1 to 121 months [mean:(28.6 ± 22.7)months] in 43 patients,and all of them survived. Primary hyperthyroidism complicated with occult thyroid carcinoma is commonly found in female patients. Preoperative diagnosis is difficult. Ultrasound is the major examining method. Frozen section can increase the detection rate. The postoperative prognosis of hyperthyroidism complicated with occult thyroid carcinoma is satisfactory.

Bilateral recurrent laryngeal nerve (RLN) palsy following total thyroidectomy is a rare complication, however, poses significant morbidity to the patient when it does occur. The purpose of this paper was to determine the incidence of bilateral RLN palsy in a specialized thyroid unit and determine whether the routine use of intraoperative nerve monitoring (IONM) would alter the outcome. This is a retrospective review of prospectively gathered data. A total of 7406 patients underwent total thyroidectomy at the University of Sydney Endocrine Surgical Unit between January 1990 and February 2014. IONM was utilized on a selective basis and we sought to assess whether IONM would have altered outcome in those patients who developed bilateral RLN palsy. Of the 7406 patients who underwent total thyroidectomy, seven patients (0.09%) developed bilateral RLN palsy during the study period. There was one permanent RLN palsy (0.01%) and routine IONM may have prevented one death and altered the outcome in two of the seven patients. Bilateral RLN palsy is a rare entity occurring in one out of 1000 cases in a specialized thyroid unit. IONM may facilitate the decision to pursue delayed surgery where the signal is lost on the first surgical side and has the potential to avoid bilateral RLN palsy following total thyroidectomy. © 2015 Royal Australasian College of Surgeons.

The aim of this study was to describe a technique using the fascia lata (FL) component of the anterolateral thigh (ALT) flap to re-create the orbital floor and lateral nasal wall after total maxillectomy. Retrospective analysis of medical records. A total of 22 patients underwent maxillary reconstruction using a composite ALT-FL flap following cancer resection. All patients underwent total maxillectomies via the Weber-Ferguson approach. The ALT flap was harvested with the deep fascia of the thigh with the aim of using it for lining of the orbital floor and lateral nasal cavity. The FL was sutured to the palatine bone inferiorly, nasal bone and zygomatic bone superiorly, and nasopharyngeal mucosa posteriorly to provide an orbital floor and make a neonasal cavity. There was 100% free flap survival. Speech was normal in eight (36%) patients, near normal in 10 (46%), and intelligible in four (18%). Seventeen (77%) patients gained a good facial appearance, and five (23%) a fair appearance. Sixteen (73%) patients complained of mild nasal crust formation, and the rest (27%) developed moderate crust. Microvascular reconstruction using a composite ALT-FL flap provided a reliable fascial component for orbital floor and nasal surface reconstruction of total maxillectomy defects.

To investigate risk factors associated with right paraesophageal lymph node (RPELN) metastasis in patients with papillary thyroid carcinoma (PTC) and to determine the indications for right lymph node dissection. Clinicopathologic data from 829 patients (104 men and 725 women) with PTC, operated on by the same thyroid surgery team at the First Affiliated Hospital of Harbin Medical University from January 2013 to May 2017, were analyzed. Overall, 309 patients underwent total thyroidectomy with bilateral lymph node dissection, 488 underwent right thyroid lobe and isthmic resection with right central compartment lymph node dissection, and 32 underwent near-total thyroidectomy (ipsilateral thyroid lobectomy with contralateral near-total lobectomy) with bilateral lymph node dissection. The overall rate of central compartment lymph node metastasis was 43.5% (361/829), with right central compartment lymph node and RPELN metastasis rates of 35.5% (294/829) and 19.1% (158/829), respectively. Tumor size, number, invasion, and location, lymph node metastasis, right central compartment lymph node metastasis, and right lateral compartment lymph node metastasis were associated with RPELN in the univariate analysis, whereas age and sex were not. Multivariate analysis identified tumors with a diameter ≥ 1 cm, multiple tumors, tumors located in the right lobe, right central compartment lymph node metastasis, and right lateral compartment lymph node metastasis as independent risk factors for RPELN metastasis. Lymph node dissection, including RPELN dissection, should be performed for patients with PTC with a tumor diameter ≥ 1 cm, multiple tumors, right-lobe tumors, right central compartment lymph node metastasis, or suspected lateral compartment lymph node metastasis.

Old age is regarded as the risk factor of major abdominal surgery due to the lack of functional reserve and the increased presence of comorbidities. This study aimed to evaluate the impact of old age on the surgical outcomes of totally laparoscopic gastrectomy for gastric cancer. This study enrolled 389 gastric cancer patients who underwent totally laparoscopic gastrectomy at Hanyang University Guri Hospital and ASAN Medical Center. The patients were classified into two groups according to age as those older than 70 years and those younger than 70 years. Early surgical outcomes such as operation time, postoperative complications, time to first flatus, days until soft diet began, and hospital stay were evaluated. No patient was converted to open surgery. The two groups differed significantly in terms of overall postoperative complication rate, time to first flatus, days until soft diet began, and hospital stay. The patients who underwent Roux-en-Y gastrojejunostomy differed in incidence of postoperative ileus but not in severe postoperative complication rate. The results of this study demonstrated that old age can have an effect on the surgical outcomes of totally laparoscopic gastrectomy. This study especially showed that elderly patients are affected by the return of bowel movement after totally laparoscopic gastrectomy. On the other hand, however, it is presumed that old age has not had a serious impact on surgical outcomes in totally laparoscopic gastrectomy because no difference in the severe postoperative complication rate was observed.

Parotidectomy surgeries are being routinely performed by ENT surgeons nowadays. Parotid tumours can present with a variety of manifestations ranging from a barely noticeable mass to a large tumour with facial paralysis. Most benign parotid tumours are located in the superficial lobe though rarely deep lobe may also be involved, while malignant tumours are generally seen to involve both the lobes of the gland. We present clinico-radiological-pathological profile of 25 patients who underwent parotid surgeries for tumours involving deep lobe alone or the whole gland, and were operated at our institute during the period from January 2011 to December 2012. This study was a retroprospective observational analysis with the aim of analyzing the epidemiology, radiological, surgical and histopathological profile of these patients. Among 25 patients who underwent parotid surgeries, 17 patients underwent total conservative parotidectomy, while 5 patients underwent radical parotidectomy. In 3 patients, extended radical parotidectomy was performed. We also report the complications and follow-up of these patients. We concluded that fine needle aspiration cytology (FNAC) findings and final histopathological report may not always correlate.

The aim of this study was to clarify the usefulness of colour-changing gum in evaluating masticatory performance after mandibulectomy. Thirty-nine patients who underwent mandibulectomy between 1982 and 2010 at Kobe University Hospital were recruited in this study. There were 21 male and 18 female subjects with a mean age of 64·7 years (range: 12-89 years) at the time of surgery. The participants included six patients who underwent marginal mandibulectomy, 21 patients who underwent segmental mandibulectomy and 12 patients who underwent hemimandibulectomy. The masticatory function was evaluated using colour-changing chewing gum, gummy jelly and a modified Sato's questionnaire. In all cases, the data were obtained more than 3 months after completing the patient's final prosthesis. The colour-changing gum scores correlated with both the gummy jelly scores (r = 0·634, P < 0·001) and the total scores of the modified Sato's questionnaire (r = 0·537, P < 0·001). In conclusion, colour-changing gum is a useful item for evaluating masticatory performance after mandibulectomy. © 2013 John Wiley & Sons Ltd.

Idiopathic thrombocytopenic purpura (ITP) is an autoimmune disorder leading to low platelet count and an increased risk of bleeding. Major joint replacement surgery in a patient with ITP can be associated with severe postoperative bleeding. We present our experience of perioperative management in a patient with severe refractory chronic idiopathic thrombocytopenic purpura who successfully underwent a cemented total knee replacement.

Chronic total occlusion (CTO) remains a challenge in interventional cardiology. We investigated the feasibility and reliability of copper wire stents and levo-polylactic acid (l-PLA) as a means of CTO induction in a porcine model. In one group of 20 swine, copper stents were crimped on a 3.0mm angioplasty balloon and inserted into the mid-left anterior descending coronary artery (LAD). In the other group of 20 swine, l-PLA was wrapped on a guidewire and pushed into the distal LAD with a 3.0mm balloon catheter to induce embolization. Of 20 swine which underwent copper stent implantation, 13 died of stent thrombosis. In the remaining 7 swine, total or near total occlusion with collateral circulation was observed at 5 weeks. Of 20 swine which underwent l-PLA embolization, 4 died of ventricular fibrillation during or shortly after the procedure. Serial histopathologic studies showed complete absorption of the polymer with replacement by fibrotic tissue approximately 4 weeks following the polymer implantation. CTO could be reliably induced in porcine coronary arteries by copper stents and l-PLA. These models may support investigation of new percutaneous devices to facilitate CTO interventions.

Endometriosis is a common finding in premenopausal women and a significant number of cases presenting digestive tract involvement at the time of diagnosis. However, most of these patients present pelvic nodules involving the rectosigmoidian junction, other digestive tract segments being less commonly affected. We present the case of a 37-year-old nulliparous woman who presented for diffuse abdominal pain and vomiting; she was diagnosed with complete ileocecal obstruction due to an endometriosis nodule in association with bilateral ovarian endometriosis lesions invading the rectosigmodian wall. A right colectomy with ileocolic anastomosis in association with bilateral cystectomy and rectosigmodian resection was successfully performed. The histopathological examination confirmed the endometriosic origin of the nodules invading the rectosigmodian and ileocecal wall, that was similar to the one described at the level of the ovarian cysts.

A 63-year-old man who had undergone radical cystectomy and ileal conduit formation for invasive bladder cancer 3 years before presented with continuous positive urinary cytology in the ileal conduit. His diagnosis was carcinoma in situ (CIS) of the left upper urinary tract. He was treated with Bacillus Calmette-Guérin (BCG) perfusion therapy using a single-J ureteric stent. BCG (80 mg) in 100 ml saline was instilled in a one-hour period weekly for 6 weeks. Usage of another catheter was effective for continuing the therapy. Urinary cytology in the left upper urinary tract and the ileal conduit became negative after the therapy. There was no evidence of recurrence or metastasis of urothelial carcinoma 6 months after the therapy.
