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.

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.

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 study the feasibility and safety of laparoscopic radical cystectomy with intracorporeal orthotopic ileal neobladder and to evaluate the role of endoscopic stapling in neobladder construction. Fifty-five patients with bladder cancer who underwent laparoscopic radical cystectomy were retrospectively examined. Extended pelvic lymph node dissection was performed before cystectomy. An ileal segment of 50 cm was harvested to construct a U-shaped reservoir. The bottom of the reservoir was anastomosed with the posterior urethra. Twenty-five patients underwent neobladder construction by manual suturing and 30 patients by endoscopic stapler suturing. The mean operative time was 346 minutes, and mean neobladder construction time was 230 minutes. The median estimated blood loss was 500 mL, and 17 patients received intraoperative transfusion. Postoperative complications included 2 cases of urine leakage, 7 cases of pyelonephritis, 4 cases of incomplete bowel obstruction, 1 case of anastomotic stricture, and 1 case of death. Endoscopic stapler suturing for neobladder construction took significantly less time than manual suturing. However, neobladder stones were found in 2 patients who underwent operation using endoscopic suturing, and the stones were removed cystoscopically. The functional outcomes of the 2 constructive methods were comparable. Laparoscopic radical cystectomy with intracorporeal orthotopic neobladder is safe and feasible for experienced laparoscopic surgeons. Application of endoscopic stapler simplifies the surgical procedure while increasing the risk of neobladder stone formation. Copyright © 2015 Elsevier Inc. All rights reserved.

Chronic urticaria and irregular menstrual cycle: a case report of effective therapy with oral contraception.

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.

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.

National survey of the current management of endometriomas in women undergoing assisted reproductive treatment.

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.

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.

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.

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.

The aim of this study was to compare the oncologic and reproductive outcomes of patients with borderline ovarian tumours (BOTs) who were treated with cystectomy or unilateral salpingo-oophorectomy (USO). The medical records of patients with BOTs who were treated between 1997 and 2009 were reviewed retrospectively. The recurrence rates were compared between the USO and cystectomy groups. The reproductive outcomes were assessed by telephone interviews. Patients with BOTs underwent a USO (n= 117) or cystectomy (n= 38). There were 12 patients who had recurrences: 1 patient had an invasive recurrence and 11 had borderline recurrences. The recurrence rate in the USO group (6.0%) was lower than in the cystectomy group (13.2%); however, this difference was not statistically significant (P= 0.110). All of the patients with recurrences were successfully treated with surgery and there was no clinical evidence of disease. Of the 116 patients contacted by telephone, 113 (97.4%) resumed menstruation following the surgery, and 45 of the 52 patients (86.5%) who attempted to conceive had successful pregnancies. USO (89.2%), like cystectomy (85.7%), resulted in excellent pregnancy rates for patients with BOTs. A USO is an appropriate treatment for women with BOTs who wish to preserve fertility. However, a cystectomy is a satisfactory fertility-sparing therapy when a cystectomy is the only surgical option.

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.

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

PubMed

Liss, Michael A; Kader, A Karim

2013-06-01

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.

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.

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

Pruthi, Raj S; Smith, Angela; Wallen, Eric M

2008-11-01

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.

Effects of previous ovarian surgery on the follicular response to ovulation induction in an in vitro fertilization program.

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.

Robotic assisted surgery is not yet widely applied in the pediatric field. 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.

Surgical diminished ovarian reserve after endometrioma cystectomy versus idiopathic DOR: comparison of in vitro fertilization outcome.

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. The authors have no competing interests to declare. © The Author 2015. Published by Oxford University Press on behalf of the European Society of Human Reproduction and Embryology.

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.

Pheochromocytoma of the urinary bladder is an unusual tumor that typically presents with hypertensive crises related to micturition. We report here an unusual case of bladder pheochromocytoma that was treated by robotic-assisted laparoscopic partial cystectomy. A 35-year-old male patient presented with headache and hypertension related to micturition. The patient, who had a 3.5 × 4 cm solitary bladder tumor in the bladder dome, underwent robot-assisted partial cystectomy. The whole procedure was successfully performed using the robot without conversion to open surgery. The total operative time was 120 min and the estimated blood loss was 30 ml. Copyright © 2011 S.

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.

Partial Cystectomy for Atypical Isolated Recurrence of Ovarian Adenocarcinoma - A Case Report and Literature Review.

PubMed

Bacalbasa, Nicolae; Balescu, Irina

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.

Laparoscopic Removal of a Large Ovarian Mass Utilizing Planned Trocar Puncture

PubMed Central

2012-01-01

Background: Large cystic ovarian masses pose technical challenges to the laparoscopic surgeon. Removing large, potentially malignant specimens must be done with care to avoid the leakage of cyst fluid into the abdominal cavity. Case: We present the case of a large ovarian cystic mass treated laparoscopically with intentional trocar puncture of the mass to drain and remove the mass. Discussion: Large cystic ovarian masses can be removed laparoscopically with intentional trocar puncture of the mass to facilitate removal without leakage of cyst fluid. PMID:22906344

An economic evaluation of laparoscopic ovarian diathermy versus gonadotrophin therapy for women with clomiphene citrate-resistant polycystic ovarian syndrome.

PubMed

Farquhar, Cynthia M

2005-08-01

Women with polycystic ovarian syndrome are typically anovulatory and require ovulation induction. Ovarian wedge resection was the first treatment for anovulation but was eventually abandoned because of the increased risk of postsurgical adhesions and as medical ovulation induction with clomiphene and gonadotrophins was introduced. However, with the advent of laparoscopy, there has been a return to surgical approaches. The potential advantages of laparoscopic surgery include avoidance of hyperstimulation and the lowered costs make ovarian surgery an attractive alternative to gonadotrophins. Clinical trials in New Zealand and the Netherlands have compared costs of laparoscopic ovarian drilling with gonadotrophins. The total cost of treatment in the Netherlands study for the ovarian drilling group was euro 4664 and for the gonadotrophins group was euro 5418. Without the cost of monitoring and the diagnostic laparoscopy then the difference was euro 2110 in favour of ovarian drilling. It was estimated that the cost per term pregnancy would be euro 14,489 for gonadotrophin and euro 11,301 for ovarian drilling (22% lower). The higher rates of multiple pregnancy in the gonadotrophin group were considered to be responsible for the increased costs. In the New Zealand trial the costs of a live birth were one-third lower in the group that underwent laparoscopic ovarian diathermy compared with those women who received gonadotrophins (NZ$19,640 and 29,836, respectively). Treating women with clomiphene-resistant polycystic ovarian syndrome with laparoscopic ovarian diathermy results in reduced direct and indirect costs. The reduction in multiple pregnancies makes the alternative of surgery particularly attractive.

Paraovarian cysts are very uncommon in children To present a case of giant paraovarian cyst case in a child and its management using a modified laparoscopic-assisted technique A 13-year-old patient with a 15 day-history of intermittent abdominal pain, located in the left hemiabdomen and associated with progressive increase in abdominal volume. 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.

This study aimed to evaluate the efficacy of unilateral laparoscopic ovarian drilling versus bilateral laparoscopic ovarian drilling with thermal dose adjusted according to ovarian volume in clomiphene citrate (CC)-resistant PCOS patients in terms of endocrine changes, menstrual cycle resumption, ovulation and pregnancy rates. This study was conducted in the Department of Obstetrics and Gynecology, Zagazig university hospitals. One hundred CC-resistant PCOS patients were divided into two groups. Group (I) (50 patients) underwent unilateral laparoscopic ovarian drilling with thermal dose adjusted according to ovarian volume (60 J/cm 3 of ovarian tissue), and group (II) (50 patients) underwent bilateral laparoscopic ovarian drilling using the same previously mentioned thermal dose. Endocrinal changes and menstrual cycle resumption were assessed within 8 weeks postoperatively, but the ovulation and pregnancy rates were estimated after 6-month follow-up period. There was no statistically significant difference between the two groups as regards demographic data ( p  > 0.05). As regards menstruation cycle resumption (62.5 vs. 81%) ( p  = 0.047), total ovulation rate (54.2 vs. 78.7%) ( p  = 0.011) and cumulative pregnancy rate (33.3 vs. 55.3%) ( p  = 0.031), there was statistically significant difference between both groups. After drilling, there were highly statistically significant decrease in the mean serum levels of luteinizing hormone (LH) and significant decrease in the mean serum levels of testosterone in both groups. Mean serum level of follicle stimulating hormone (FSH) did not change significantly in both groups after drilling. Bilateral laparoscopic ovarian drilling with thermal dose adjusted according to ovarian volume is more effective than the right-sided unilateral technique with thermal dose adjusted according to ovarian volume in terms of menstrual cycle resumption, ovulation and cumulative pregnancy rates in CC-resistant PCOS patients.

• 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.

The purpose of this survey was to assess the opinions of members of the German Society of Gynecologic Endoscopy (AGE) regarding the laparoscopic treatment of ovarian malignancies and current practice at their institutions. Between February and October 2015, the AGE sent an anonymous online survey via mail to its members. The questionnaire solicited participants' opinions about the laparoscopic treatment of ovarian cancers according to T stage and borderline tumors, and information about current practice at their institutions. Participants were also asked their opinions on currently available data on this issue. Of 228 AGE members who completed the survey, 132 (58%) were fellows or attending physicians and 156 (68%) worked at university hospitals or tertiary referral centers. Most [212 (93%)] respondents stated that < 10% of all ovarian cancer cases were currently treated laparoscopically at their institutions. Most participants indicated that T1 (a, b, c) tumors [145 (64%)] and ovarian borderline tumors [206 (90%)], but not T2 [48 (21%)] or T3/4 [9 (4%) ovarian tumors] should or could be treated laparoscopically. One hundred seventy-two (75%) participants considered currently available data on this topic to be insufficient and 152 (66%) stated that they would take part in a clinical trial assessing a laparoscopic approach to T1/2 ovarian cancer. According to this survey, to the opinion of the majority of AGE members, laparoscopy might be a considerable option for the treatment of early ovarian malignancies and borderline tumors and should be evaluated further in future studies.

Alborzi, S; Khodaee, R; Parsanejad, M E

2001-09-01

To evaluate endocrine and ovulatory changes in polycystic ovarian disease (PCOD) in relation to patients' ovarian size. Three hundred and seventy-one women with clomiphene citrate-resistant PCOD underwent laparoscopic ovarian cauterization [type I or typical with ovarian volume >8 cm(3) or cross-sectional area >10 cm(2) (n=211), type II with normal size ovary (n=160)]. Serum levels of LH, FSH, DHEAS, PRL, and T before and 10 days after ovarian cautery, spontaneous and induced ovulation and pregnancy rates were compared. Both groups responded to therapy in a similar manner, with a marked decrease in LH, FSH, DHEAS and T levels, with ovulation rates in type I 90.99%, type II 88.75% and pregnancy rates, 73.45% and 71.25%, respectively, with no statistical differences. Hormonal changes, ovulation and pregnancy rates were similar in the two types of PCOD, therefore it can be concluded that ovarian size is not a prognostic factor for response of PCOD patients to laparoscopic ovarian electro-cauterization.

Background: The laparoscopic approach has been proposed for treating hepatic cystic echinococcosis (HCE) and has already been used in clinical practice, mostly for non-radical operations. In this study, we aimed to evaluate the feasibility of total cystectomy of HCE under laparoscopy (LS). Results: A retrospective review of the medical records obtained from 22 patients diagnosed with HCE between June 2009 and June 2013 and treated with an LS approach was conducted in the First Affiliated Hospital of Xinjiang Medical University. A total of 15 patients underwent total cystectomy of HCE using LS. The average time of surgery was 174 min (160–210 min). Intraoperative bleeding was 103 mL (80–200 mL). The mean duration of hospitalization was 7 days (6–15 days). Seven patients were transferred to open surgery (OS). For these patients, the average duration of surgery was 177 min (150–230 min). Intraoperative bleeding was 237 mL (160–350 mL), and the mean duration of hospitalization was 10 days (8–15 days). The most frequent postoperative complications were hydrops in the surgical area (two cases in LS and three cases in OS), and temporary bile leakage (one patient in the LS group). Recurrence was not seen in any cases in either group with a follow-up of 6–12 months. Conclusions: Total cystectomy of HCE appears to be safe and effective in selected patients with unique, small-sized, superficially located cysts. To establish precise recommendations about the technique and its indications, prospective studies are necessary. PMID:25489977

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.

To structure the rate of intraoperative complications that requires an intraoperative or perioperative resolution. We perform a literature review of Medline database. The research was focused on intraoperative laparoscopic procedures inside the field of urological oncology. General rate of perioperative complications in laparoscopic urologic surgery is described to be around 12.4%. Most of the manuscripts published do not make differences between pure intraoperative, intraoperative with postoperative consequences and postoperative complications. We expose a narrative statement of complications, possible solutions and possible preventions for most frequent retroperitoneal and pelvic laparoscopic surgery. We expose the results with the following order: retroperitoneal laparoscopic surgery (radical nephrectomy, partial nephrectomy, nephroureterectomy and adrenalectomy) and pelvic laparoscopic surgery (radical prostatectomy and radical cystectomy). Intraoperative complications vary from different series. More scheduled reports should be done in order to better understand the real rates of complications.

BACKGROUND AND OBJECTIVE: There is no available evidence to recommend gonadotropin-releasing hormone (GnRH) analogue-based ovarian suppression versus bilateral salpingo-oophorectomy (BSO) in the adjuvant treatment of early breast cancer, since the two approaches are considered equivalent in terms of oncologic outcome. The role of surgical ovarian ablation has been revitalized based on the advances of minimally invasive surgery, and a better understanding of clinical and molecular basis of hereditary breast/ovarian cancer syndromes. The aim of this study is to analyze the cost-effectiveness of laparoscopic BSO and GnRH analogue administration in patients aged 40-49 years with hormone-sensitive breast cancer. A probabilistic decision tree model was developed to evaluate costs and outcomes of ovarian ablation through laparoscopic BSO, or ovarian suppression through monthly injections of GnRH analogue. Results were expressed as incremental costs per quality-adjusted life years (QALYs) gained. Laparoscopic BSO strategy was associated with a lower mean total cost per patient than GnRH treatment, and considering the difference in terms of QALYs, the incremental effectiveness did not demonstrate a notable difference between the two approaches. From the National Health Service perspective, and for a time horizon of 5 years, laparoscopic BSO was the dominant option compared to GnRH treatment; laparoscopic BSO was less expensive than GnRH, €2385 [95% confidence interval (CI) = 2044, 2753] vs €7093 (95% CI = 3409, 12,105), respectively, and more effective. Surgical ovarian ablation is more cost-effective than GnRH administration in the adjuvant treatment of hormone-sensitive breast cancer patients aged 40-49 years, and the advantage of preventing ovarian cancer through laparoscopic BSO should be considered.

Ovarian cryopreservation after laparoscopic ovariectomy using the Endo-GIA stapling device and LAPRO-clip absorbable ligating clip in a woman: a case report

PubMed Central

2011-01-01

Introduction Several options are available for preserving fertility before cytotoxic treatment, including ovarian tissue cryopreservation. Most reported surgical techniques include electrocoagulation. Our hypothesis is that avoidance of electrocoagulation may decrease ovarian cortex injury during cryopreservation procedures. Case presentation We report a laparoscopic technique of whole-ovary removal without coagulation using Endo-GIA forceps and clips. Laparoscopic ovariectomy was performed for cryopreservation in a 37-year-old Caucasian woman with breast cancer and for whom chemotherapy was planned. The procedure was completed quickly and without complication. This Endo-GIA procedure was of short duration with a short period of ischemia before freezing. Conclusion Laparoscopic ovariectomy using the Endo-GIA stapling device procedure without coagulation may diminish ovary injury before ovarian cryopreservation. PMID:21291518

2011-08-01

Inguinal hernia repair is one of the most common operation in surgical practice. Despite its common occurrence, hernia often poses a surgical dilemma even for a skilled surgeon. The unexpected hernial content constitutes one of these cases. Although the often-reported, unusual contents of a hernia sac include ovary, fallopian tube, vermiform appendix, Meckel diverticulum, and urinary bladder, the herniation of a large ovarian cyst into the inguinal canal has been hardly reported. Majority of the ovarian cysts are asymptomatic or present with vague lower abdominal pain, whereas the presentation of a large ovarian cyst as an inguinolabial swelling as in our patient is extremely rare. We present here one of the few reported cases of a laparoscopic excision of a large ovarian cyst herniating into the inguinal canal and discuss the pathogenesis of an ovarian cyst as hernial content, the advantages and concerns of a laparoscopic approach in resecting large ovarian cysts, and simultaneous management of the inguinal hernia.

2017-01-01

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.

Unilateral laparoscopic ovariectomy was attempted in a red fox (Vulpes vulpes) with an ovarian cyst through single portal access. The ovarian cyst was resistant to conservative therapy using gonadotropin-releasing hormone. A 10-mm laparoscope with an operating channel was introduced into the abdomen via a 12-mm umbilical portal. The left ovary and cyst (34.1 x 30.8 mm) were fixed to the left abdominal wall by a transabdominal suspension suture. The ovarian pedicles and ligaments were progressively cauterized and transected with a multifunction bipolar electrocoagulation forceps. The resected cystic ovary was exteriorized through the umbilical portal site. The surgical time was 42 min, and no intra- and postoperative complications were encountered. Two months after the surgery mating was observed, and the fox gave birth to three healthy cubs 56 days after the mating. This is the first report of using laparoscopy in the red fox with an ovarian cyst.

Mature cystic teratomas are the most common among all ovarian neoplasms, representing 30-40% of the cases. However, to the best of our knowledge, there have been only two reports of mature cystic teratomas occurring in identical twins to date. We herein report a case of identical twins with mature cystic teratomas who were treated with laparoscopic surgery. A 32-year-old woman was referred to our hospital due to a tumor in the right ovary. The patient underwent laparoscopic resection of the ovarian tumor and the pathological diagnosis was benign mature cystic teratoma. Two years later, the identical twin of the abovementioned patient was referred to our hospital also due to a right ovarian tumor. The patient underwent laparoscopic resection of the ovarian tumor and the pathological diagnosis was benign mature cystic teratoma. Therefore, for early diagnosis, it may be important to consider the possibility of mature cystic teratoma in the identical twin of a patient, even in the absence of symptoms.

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.

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.

Struma Ovarii in Pregnancy: An Uncommon Cause of Hyperthyroidism.

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.

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.

The article presents French guidelines for surgical management of endometriosis. Surgical treatment is recommended for mild to moderate endometriosis, as it decreases pelvic painful complaints and increases the likelihood of postoperative conception in infertile patients (A). Surgery may be proposed in symptomatic patients with ovarian endometriomas which diameter exceeds 20mm. Cystectomy allows for better postoperative pregnancy rates when compared to ablation using bipolar current, as well as for lower recurrences rates when compared to ablation using bipolar current or CO 2 laser. Ablation of ovarian endometriomas using bipolar current is not recommended (B). Surgery may be employed in patients with deep endometriosis infiltrating the colon and the rectum, with good impact on painful complaints and postoperative conception. In these patients, laparoscopic route increases the likelihood of postoperative spontaneous conception when compared to open route. When compared to conservative rectal procedures (shaving or disc excision), segmental colorectal resection increases the risk of postoperative stenosis, requiring additional endoscopic or surgical procedures. In large deep endometriosis infiltrating the rectum (>20mm length of bowel infiltration), conservative rectal procedures do not improve postoperative digestive function when compared to segmental resection. In patients with bowel anastomosis, placing anti-adhesion agents on contact with bowel suture is not recommended, due to higher risk of bowel fistula (C). Various other recommendations are proposed in the text, however, they are based on studies with low level of evidence. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

Complications from robot-assisted radical cystectomy: Where do we stand?

2016-03-01

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.

This prospective cohort study was conducted on 80 patients with clomiphene citrate (CC)-resistant polycystic ovary syndrome undergoing laparoscopic ovarian drilling (LOD). Pre- and post-LOD ovarian reserve parameters (anti-Mullerian hormone: AMH, ovarian volume: OV, and antral follicle count: AFC) and ovarian stromal blood flow indices (Vascularization index: VI, flow index: FI, and vascularization flow index: VFI) were measured to explore the effect of LOD and to find out the correlation between serum AMH and different clinical, hormonal, and ultrasonic variables. There was a highly significant reduction of the serum AMH (p < .001) after LOD with significant reduction in OV, AFC and vascular indices (VI, FI and VFI) of the right and left ovaries (p < .05). LOD significantly reduced ovarian reserve parameters (AMH, OV and AFC) and ovarian stromal blood flow indices (VI, FI and VFI) with no observed correlation between AMH levels and Doppler indices.

To assess the changes in hormonal profile (serum FSH, LH, prolactin and total testosterone) following laparoscopic ovarian drilling (LOD) in patients with polycystic ovarian syndrome. Fifty patients with PCOS have been included in this study. Serum prolactin, total testosterone, follicular-stimulating hormone (FSH) and luteinizing hormone (LH) levels have been used as biochemical markers, before and after procedures. Laparoscopic ovarian drilling was successfully employed without any surgical complications and on an average follow-up time of 24 weeks after the procedure. During the follow-up serum values for prolactin, total testosterone and LH have decreased significantly and FSH levels remained unchanged after the procedure. The LOD in patients with PCOS may avoid or reduce the risk of OHSS and the multiple pregnancy rate induced by gonadotropin therapy. The high pregnancy rate and the economic aspect of the procedure offer an attractive management for patients with PCOS. However, LOD can be considered as second-line treatment after clomiphene citrate treatment failure and/or resistance.

Growing evidence supports the safety of a laparoscopic approach for patients affected by apparent early-stage ovarian cancer. However, no well-designed studies comparing laparoscopic and open surgical staging are available. In the present investigation we aimed to provide a balanced long-term comparison between these 2 approaches. Retrospective study (Canadian Task Force classification II-2). Tertiary center. Data of consecutive patients affected by early-stage ovarian cancer who had laparoscopic staging were matched 1:1 with a cohort of patients undergoing open surgical staging. The matching was conducted by a propensity-score comparison. Laparoscopic and open surgical staging. Fifty patient pairs (100 patients: 50 undergoing laparoscopic staging vs 50 undergoing open surgical staging) were included. Demographic and baseline oncologic characteristics were balanced between groups (p > .2). We observed that patients undergoing laparoscopic staging experienced longer operative time (207.2 [71.6] minutes vs 180.7 [47.0] minutes; p = .04), lower blood loss (150 [52.7] mL vs 339.8 [225.9] mL; p < .001), and shorter length of hospital stay (4.0 [2.6] days vs 6.1 [1.6] days; p < .001) compared with patients undergoing open surgical staging. No conversion to open surgery occurred. Complication rate was similar between groups. No difference in survival outcomes were observed, after a mean (SD) follow-up of 49.5 (64) and 52.6 (31.7) months after laparoscopic and open surgical staging, respectively. Our findings suggest that the implementation of minimally invasive staging does not influence survival outcomes of patients affected by early-stage ovarian cancer. Laparoscopic staging improved patient outcomes, reducing length of hospital stay. Further large prospective studies are warranted. Copyright © 2016 AAGL. Published by Elsevier Inc.

To compare the efficacy of clomiphene citrate (CC) plus tamoxifen with that of laparoscopic ovarian drilling in clomiphene-resistant women with polycystic ovary syndrome (PCOS). We randomly allocated 150 women with CC-resistant PCOS to a combined medication group (group 1) or a laparoscopic surgery group (group 2). The primary outcome was the live birth rate in each group; secondary outcomes were the rates of ovulation, clinical pregnancy and miscarriage. There were no significant differences between the groups regarding rates of ovulation (81.3% vs 85.3%), pregnancy (53.3% vs 50.7%), or live births (49.3% vs 44.0%), but the mean endometrium thickness was significantly greater on the day of human chorionic gonadotropin administration in group 1 (P<0.001). Clomiphene citrate plus tamoxifen was as effective as laparoscopic ovarian drilling in promoting ovulation and pregnancy.

Laparoscopic ovarian drilling: An alternative but not the ultimate in the management of polycystic ovary syndrome

Since its introduction in 1984, laparoscopic ovarian drilling has evolved into a safe and effective surgical treatment for anovulatory, infertile women with polycystic ovary syndrome (PCOS), unresponsive to clomiphene citrate. It is as effective as gonadotropins in terms of pregnancy and live birth rates, but without the risks of ovarian hyperstimulation syndrome and multiple pregnancies. It improves ovarian responsiveness to successive ovulation induction agents. Its favorable reproductive and endocrinal effects are sustained long. Despite its advantages, its use in unselected cases of PCOS or for non-fertility indications is not prudent owing to the potential risks of iatrogenic adhesions and ovarian insufficiency.

Laparoscopic Treatment of Mixed Malignant Ovarian Germ Cell Tumor in a 16-Year-Old Female Adolescent.

PubMed

Friedman, Caroline; Fenster, Tamatha

2016-12-01

Malignant ovarian germ cell tumors are rare entities, although they account for a large proportion of ovarian masses in young women. These tumors have traditionally been removed via laparotomy, because of their large size and solid nature. The use of laparoscopy for treatment of adnexal masses in adolescents has been heavily debated and poorly studied to date. A 16-year-old female patient presented with abdominal pain and an 11-cm adnexal mass on ultrasound. An emergent laparoscopic salpingo-oophorectomy was performed without complication. Pathology revealed a mixed malignant ovarian germ cell tumor. Laparoscopic fertility-sparing surgery offers many benefits over laparotomy, and should be considered in cases of young women with large adnexal masses, even if potential for malignancy exists.

From September 1992 to September 1993, 150 patients aged 15-68 years underwent laparoscopic gynecologic surgery. These patients included 63 patients with acute abdominal diseases (46 had ectopic pregnancy, 9 rupture of ovary, and 8 torsion of ovarian cyst), which consisted of 90% of total patients with acute abdomen in corresponding period, 63 patients with mass of adnexa, which made up 72% of total patients with ovarian tumors, and 24 patients with uterine diseases. We successfully performed laparoscopic salpingostomy, fallotomy, removal of ovarian cyst, oophorosalpingectomy, myomectomy and laparoscopy assisted vaginal hysterectomy (LAVH) with 2-4 puncture technic after general anesthesia. The largest ovarian tumor and the enlarged uterus were 14 and 16 cm in diameter respectively. Four patients had laparotomy because of severe pelvic adhesions and the laparotomy rate was about 2.6%. The procedure lasted 20-240 minutes and bleeding was less than 200ml. No major surgical complication was encountered.

The role of ovarian surgery in polycystic ovary syndrome.

PubMed

Farquhar, Cynthia M

2004-10-01

Problems in inducing ovulation in women with polycystic ovary syndrome (PCOS) and anovulation are well recognized. In 1935, Stein and Leventhal first described surgical treatment by ovarian wedge resection at laparotomy for women with anovulation and PCOS. Ovarian wedge resection was eventually abandoned because of the significant risk of postsurgical adhesion formation, which resulted in tubal adhesions, and because of the advent of medical ovulation induction with clomiphene and gonadotrophins. However, since the arrival of minimally invasive surgical techniques, laparoscopic ovarian surgery has become feasible. The potential advantages of laparoscopic ovarian surgery include repeated single ovulations and less adhesion formation. Lowered costs make ovarian surgery an attractive alternative to gonadotrophins. However, although many case series have suggested that ovarian surgery is an effective strategy, few randomized, controlled trials have been undertaken comparing the success rates of surgery with gonadotrophins. The long-term concerns with surgery include adhesion formation and premature ovarian failure.

Whereas advances in minimally invasive surgery have made laparoscopic staging technically feasible in stage I epithelial ovarian cancer, the practice remains controversial because of an absence of randomized trials and lack of high-quality observational studies demonstrating equivalent outcomes. This study seeks to evaluate the association of laparoscopic staging with survival among women with clinical stage I epithelial ovarian cancer. We used the National Cancer Data Base to identify all women who underwent surgical staging for clinical stage I epithelial ovarian cancer diagnosed from 2010 through 2012. The exposure of interest was planned surgical approach (laparoscopy vs laparotomy), and the primary outcome was overall survival. The primary analysis was based on an intention to treat: all women whose procedures were initiated laparoscopically were categorized as having had a planned laparoscopic procedure, regardless of subsequent conversion to laparotomy. We used propensity methods to match patients who underwent planned laparoscopic staging with similar patients who underwent planned laparotomy based on observed characteristics. We compared survival among the matched cohorts using the Kaplan-Meier method and Cox regression. We compared the extent of lymphadenectomy using the Wilcoxon rank-sum test. Among 4798 eligible patients, 1112 (23.2%) underwent procedures that were initiated laparoscopically, of which 190 (17%) were converted to laparotomy. Women who underwent planned laparoscopy were more frequently white, privately insured, from wealthier ZIP codes, received care in community cancer centers, and had smaller tumors that were more frequently of serous and less often of mucinous histology than those who underwent staging via planned laparotomy. After propensity score matching, time to death did not differ between patients undergoing planned laparoscopic vs open staging (hazard ratio, 0.77, 95% confidence interval, 0.54-1.09; P = .13). Planned laparoscopic staging was associated with a slightly higher median lymph node count (14 vs 12, P = .005). Planned laparoscopic staging was not associated with time to death after adjustment for receipt of adjuvant chemotherapy, histological type and grade, and pathological stage (hazard ratio, 0.82, 95% confidence interval, 0.57-1.16). Surgical staging via planned laparoscopy vs laparotomy was not associated with worse survival in women with apparent stage I epithelial ovarian cancer. Copyright © 2016 Elsevier Inc.

This was a prospective controlled study to compare the beneficial effects of office microlaparoscopic ovarian drilling (OMLOD) under augmented local anesthesia, as a new modality treatment option, compared to those following ovarian drilling with the conventional traditional 10-mm laparoscope (laparoscopic ovarian drilling, LOD) under general anesthesia. The study included 60 anovulatory women with polycystic ovary syndrome (PCOS) who underwent OMLOD (study group) and 60 anovulatory PCOS women, in whom conventional LOD using 10-mm laparoscope under general anesthesia was performed (comparison group). Transvaginal ultrasound scan and blood sampling to measure the serum concentrations of LH, FSH, testosterone and androstenedione were performed before and after the procedure. Intraoperative and postoperative pain scores in candidate women were evaluated during the office microlaparoscopic procedure, in addition to the number of candidates who needed extra analgesia. Women undergoing OMLOD showed good intraoperative and postoperative pain scores. The number of patients discharged within 2 h after the office procedure was significantly higher, without the need for postoperative analgesia in most patients. The LH:FSH ratio, mean serum concentrations of LH and testosterone and free androgen index decreased significantly after both OMLOD and LOD. The mean ovarian volume decreased significantly (P < 0.05) a year after both OMLOD and LOD. There were no significant differences in those results after both procedures. Intra- and postoperatively augmented local anesthesia allows outpatient bilateral ovarian drilling by microlaparoscopy without general anesthesia. The high pregnancy rate, the simplicity of the method and the faster discharge time offer a new option for patients with PCOS who are resistant to clomiphene citrate. Moreover, ovarian drilling could be performed simultaneously during the routine diagnostic microlaparoscopy and integrated into the fertility workup of these patients.

Laparoscopic management of a twisted ovarian leiomyoma in a woman with 10 weeks' gestation: Case report and literature review.

PubMed

Primary leiomyoma of the ovary is a rare benign ovarian tumor that only seldom causes acute abdomen. A 35-year-old gravida 1, para 0 woman presented with a history of acute lower abdominal pain, and 10 weeks of amenorrhea. The patient's physical examination revealed abdominal tenderness, defense, and rebound. On ultrasonographic examination, a solid mass measuring 9.3 × 7.8 cm was detected adjacent to the uterine fundus. The mass was preoperatively diagnosed as a twisted pedunculated subserosal uterine myoma. Upon entering the pelvic cavity, the mass in the right adnexa appeared twisted clockwise. Therefore, a laparoscopic salpingo-oophorectomy was performed. The tumor was pathologically diagnosed as ovarian leiomyoma. The patient delivered a healthy girl at 40 1/7 weeks of pregnancy. Despite its low incidence, torsion of ovarian leiomyoma should be considered in the differential diagnosis of acute abdomen. Furthermore, laparoscopic exploration should be the preferred way of removing twisted ovarian leiomyoma, even during pregnancy. It seems that primary ovarian leiomyomata have a tendency to grow rapidly during early pregnancy. However, because of the low incidence of ovarian leiomyoma, the effects of estrogen and pregnancy on this condition remain unclear.

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

For the period from 2003 to 2014 at the Oncogynecology Department laparoscopic surgery for ovarian cancer was performed in 49 patients aged 19 to 76 years. During the surgical interventions special attention was paid to the principles of oncological radicalism and ablastics, the volume of surgery depended on the extent of tumor process, morphological characteristics of tumor, a patient's age and the desire to preserve reproductive function. In 42 (85.7%) cases laparoscopic procedures were conducted to restaging (after non-radical operations in gynecological hospitals). In all 49 patients a histological form of ovarian tumor corresponded to adenocarcinoma. Mean operative time was 140 ± 10,5 minutes, the average blood loss--80,2 ± 14,3 ml. Postoperative complications (bleeding from the omentum) were recorded in 1 (2%) patient, the need for conversion was occurred in 4 (8.2%) cases due to the adhesive process or signs of dissemination. As a result of laparoscopic surgery an increase in staging of disease was fixed in 14 cases (28.6%). Follow-up median was 45 months, relapses occurred in 5 (10.2%) patients. Of 49 patients 2 (4.1%) died from disease progression. Disease-free and overall survival rates were 89.8% and 95.9%, respectively. Thus, data of world literature and our own experience indicate the potential equivalent of laparoscopic and laparotomy approaches in treatment for early ovarian cancer.

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.

We present a case of a 29 year old nulliparous woman with clomiphene resistance polycystic ovarian syndrome. She had a successful laparoscopic ovarian drilling (LOD) in a private fertility centre in Nnewi Southeast Nigeria. She achieved a pregnancy four months later following clomiphene citrate ovulation induction. The pregnancy was complicated with 1st trimester threatened abortion, pre-term PROM and later pre-term labour at 34 weeks gestation with breech presentation. She had a successful caesarean delivery of a 1.75 kg life female baby that was nursed in the incubator for 2 weeks before discharge. This is the first reported successful LOD in Southeast Nigeria with good pregnancy outcome.

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.

Parastomal hernia is one of the most common but challenging complication after stoma formation. Modified Sugarbaker technique is the recommended procedure for repair parastomal hernia, however, keyhole repair technique had also been used in certain instances. In cases of parastomal hernia following ileal conduit procedure, the Sugarbaker technique is been described, although with associated theoretical risk of conduit failure. We are reporting a case of post-radical cystectomy with ileal conduit presented with symptomatic large parastomal hernia. Laparoscopic modified keyhole plus repair has been done successfully in this patient with no recurrence in 2 years of follow-up. The purpose of our case report is to describe our novel modification of the laparoscopic keyhole technique which can be a feasible and acceptable alternative surgical method in these types of patients.

Sentinel lymph node (SLN) mapping has increased its feasibility in both early-stage cervical and endometrial cancer. There are few SLN studies regarding the ovary because of the risk of tumor dissemination and perhaps because the ovary represents an inconvenient site for injection. In this preliminary study, we have shown the feasibility of SLN mapping of the ovary with indocyanine green during laparoscopic retroperitoneal aortic surgical staging. The 10 women who were included in this study underwent aortic with pelvic laparoscopic staging, which included SLN biopsy, extrafascial total hysterectomy, and bilateral salpingo-oophorectomy in case of an ovarian tumor. The fluorescent dye was injected on the dorsal and ventral side of the proper ovarian ligament and the suspensory ligament, close to the ovary and just underneath the peritoneum. In all cases except 1, SLNs were detected soon after the injection in the aortic compartment and in 3 cases also in the common iliac region. Only 1 intraoperative complication occurred: a superficial lesion of the vena cava that was recovered with a laparoscopic suture. Laparoscopic ovarian SLN mapping performed by means of an injection of indocyanine green fluorescent tracer in the ovarian ligaments seems feasible and promising. Further investigation are encouraged and necessary to evaluate the possible applications of this new technique for staging patients with early-stage ovarian cancer. Copyright © 2016 AAGL.

Giant ovarian cysts are tumours of the ovary presenting with diameters greater than 10 cm. Giant ovarian cysts have become rare in recent days as they are diagnosed and managed early due to the availability of good imaging modalities. The aim of this case report is to show how a huge cystic ovarian mass can mislead the diagnosis of ascites in a postmenopausal woman. Factors associated with late presentation of giant ovarian cysts in sub-Saharan Africa have also been discussed. We present the case of a 65-year-old grand multiparous woman who was referred to our centre with a grossly distended abdomen misdiagnosed as a massive ascites. Abdominopelvic ultrasound scan revealed a right giant multiloculated ovarian cyst. She benefited from a cystectomy with an uneventful postoperative stay. Histopathology revealed mucinous cystadenoma. Large cystic ovarian tumours can present masquerading as massive ascites and misleading diagnosis as in this case report. We report this case to increase the suspicion index of a large ovarian cyst in all women presenting with massive ascites.

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.

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.

Laparoscopic ovarian drilling for clomiphene-resistant polycystic ovary syndrome.

PubMed

Flyckt, Rebecca L; Goldberg, Jeffrey M

Laparoscopic ovarian drilling (LOD) is an alternative to ovulation induction with gonadotropins for polycystic ovarian syndrome (PCOS) patients unresponsive to clomiphene. It is quick and easy to perform, although the number of punctures and energy doses has not been standardized. The mechanism of LOD is unclear, but it is likely mediated by a reduction in intraovarian androgen production. Serum luteinizing hormone and testosterone levels are rapidly normalized, and these changes are sustained over long-term follow-up. Studies have shown that ovulation and pregnancy rates are comparable between ovulation induction with gonadotropins and LOD, but LOD avoids the risks of multiple pregnancy and ovarian hyperstimulation syndrome. LOD is also more cost effective and better tolerated than gonadotropin therapy. Concerns regarding clinically significant adhesion formation and premature ovarian failure are not supported by the available data. Transvaginal hydrolaparoscopy and ultrasound guidance are less invasive techniques for performing ovarian drilling and may encourage LOD earlier in the course of treatment for PCOS. © Thieme Medical Publishers.

Objectives Ovarian cancer is the fourth leading cause of cancer-related death among women in the US largely due to late detection secondary to unreliable symptomology and screening tools without adequate resolution. Optical coherence tomography (OCT) is a recently emerging imaging modality with promise in ovarian cancer diagnostics, providing non-destructive subsurface imaging at imaging depths up to 2 mm with near-histological grade resolution (10–20 μm). In this study, we developed the first ever laparoscopic OCT (LOCT) device, evaluated the safety and feasibility of LOCT, and characterized the microstructural features of human ovaries in vivo. Methods A custom LOCT device was fabricated specifically for laparoscopic imaging of the ovaries in patients undergoing oophorectomy. OCT images were compared with histopathology to identify preliminary architectural imaging features of normal and pathologic ovarian tissue. Results Thirty ovaries in 17 primarily peri or post-menopausal women were successfully imaged with LOCT: 16 normal, 5 endometriosis, 3 serous cystadenoma, and 4 adenocarcinoma. Preliminary imaging features developed for each category reveal qualitative differences in the homogeneous character of normal post-menopausal ovary, the ability to image small subsurface inclusion cysts, and distinguishable features for endometriosis, cystadenoma, and adenocarcinoma. Conclusions We present the development and successful implementation of the first laparoscopic OCT probe. Comparison of OCT images and corresponding histopathology allowed for the description of preliminary microstructural features for normal ovary, endometriosis, and benign and malignant surface epithelial neoplasms. These results support the potential of OCT both as a diagnostic tool and imaging modality for further evaluation of ovarian cancer pathogenesis. PMID:19481241

Evidence of metachronous development of ovarian teratomas: a case report of bilateral mature cystic teratomas of the ovaries and systematic literature review.

Mature cystic teratomas are usually found in the ovaries. They are bilateral in 10 to 15% of cases and multiple cystic teratomas may be present in one ovary. The aim of this study is to clarify if development of mature cystic teratomas of the ovaries in a single host is metachronous or due to autoimplant or recurrence. We report a woman with bilateral mature cystic teratomas of the ovaries. DNA profiles of these teratomas were investigated via short tandem repeat (STR) analysis and methylation statuses were determined via methylation sensitive multiplex ligation-dependent probe amplification methods. The results showed that the cystic teratomas originated from different stages of oogonia or primary oocyte before germinal vesicle stage failure of meiosis I in female gametogenesis. Potentially relevant literature was searched in PubMed database. Cases of bilateral or multiple mature cystic teratomas of the ovaries were analyzed. To date, there has been no reported case of multiple mature cystic teratomas in which clarification of the origin was achieved using molecular genetic methods. The results of this case study provide evidence of metachronous development of mature cystic teratomas of the ovaries and may serve as a reference in the management of patients following laparoscopic cystectomy.

Biopsy pick-up (BPU) has been considered a safe method to harvest ovarian fragments from live animals. However, no studies have been reported on the use of BPU to collect in vivo ovarian tissue in goats. The goals of this study were: (i) to test different biopsy needle sizes to collect ovarian tissue in situ using the BPU method (Experiment 1), and (ii) to study ovarian tissue features such as preantral follicle density, morphology, class distribution, and stromal cell density in ovarian fragments obtained in vivo through a laparoscopic BPU method (Experiment 2). In Experiment 1, goat ovaries (n = 20) were collected in a slaughterhouse and subjected to in situ BPU. Three needles (16, 18, and 20G) were tested. In Experiment 2, the most efficient biopsy needle from Experiment 1 was used to perform laparoscopic BPU in goats (n = 8). In Experiment 1, the recovery rate was greater (P < 0.05; range 50-62%) with 16G and 18G needles than the 20G (17%) needle. The mean weight of ovarian fragments collected by the 16G needle was greater (P < 0.05) than the 18G and the 20G needle. In Experiment 2, 62 biopsy attempts were performed and 52 ovarian fragments were collected (90% success rate). Overall, 2054 preantral follicles were recorded in 5882 histological sections analyzed. Mean preantral follicular density was 28.4 ± 1.3 follicles per cm 2 . The follicular density differed (P < 0.05) among animals and ovarian fragments within the same animal. The mean stromal cell density in the ovarian fragments was 37.1 ± 0.5 cells per 2500 μm 2 , and differed (P < 0.05) among animals. Moreover, preantral follicle density and stromal cell density were associated (P < 0.001). The percentage of morphologically normal follicles was 70.1 ± 1.2, and differed (P < 0.05) among animals. The majority (79%) of the morphologically normal follicles was classified as primordial follicles, and differed (P < 0.05) among animals and between ovaries. In summary, a laparoscopic BPU method has been developed to harvest ovarian tissue in vivo with a satisfactory success rate in goats. Furthermore, this study described for the first time that goat ovarian biopsy fragments have a high heterogeneity in follicular density, morphology, class distribution, and stromal cell density.

Abstract. Ovarian cancer is the most deadly gynecologic cancer, a fact which is attributable to poor early detection and survival once the disease has reached advanced stages. Intraoperative laparoscopic volume holographic imaging has the potential to provide simultaneous visualization of surface and subsurface structures in ovarian tissues for improved assessment of developing ovarian cancer. In this ex vivo ovarian tissue study, we assembled a benchtop volume holographic imaging system (VHIS) to characterize the microarchitecture of 78 normal and 40 abnormal tissue specimens derived from ovarian, fallopian tube, uterine, and peritoneal tissues, collected from 26 patients aged 22 to 73 undergoing bilateral salpingo-oophorectomy, hysterectomy with bilateral salpingo-oophorectomy, or abdominal cytoreductive surgery. All tissues were successfully imaged with the VHIS in both reflectance- and fluorescence-modes revealing morphological features which can be used to distinguish between normal, benign abnormalities, and cancerous tissues. We present the development and successful application of VHIS for imaging human ovarian tissue. Comparison of VHIS images with corresponding histopathology allowed for qualitatively distinguishing microstructural features unique to the studied tissue type and disease state. These results motivate the development of a laparoscopic VHIS for evaluating the surface and subsurface morphological alterations in ovarian cancer pathogenesis. PMID:24676382

At present, Da Vinci robotic assisted hepatectomy has been routinely carried out in conditional units. But there is no report concerning the use of Da Vinci robots for hepatic hydatid cystectomy and experience on this aspect is seldom mentioned before. This study was to summarize the preliminary experience in laparoscopic resection of hepatic hydatidectocyst with the Da Vinci Surgical System (DVSS). A 29-year-old female diagnosed as hepatic hydatid in the right anterior lobe of liver was treated with laparoscopic resection by the DVSS under general anesthesia. Appropriate disposal of tumor cell in vascular system and disinfection of surgical field with hypertonic saline were conducted. The hepatic hydatidectocyst was resected completely with an operation time of 130 min, an intraoperative blood loss of 200 ml and a length of hospital stay for five days. The vital signs of patient were stable and no cyst fluid allergy occurred after operation. Our result showed that laparoscopic resection of hepatic hydatidectocyst by using the DVSS is safe and feasible on the basis of hospitals have rich experience in treatment of cystic echinococcosisliver, resection with DVSS and laparoscopic excision.

Ovarian endometriomas and IVF: a retrospective case-control study

PubMed Central

2011-01-01

We performed this retrospective case-control study analyzing 428 first-attempt in vitro fertilization (IVF) cycles, among which 254 involved women with a previous or present diagnosis of ovarian endometriosis. First, the results of these 254 cycles were compared with 174 cycles involving patients with proven non-endometriotic tubal infertility having similar age and body mass index. Women with ovarian endometriosis had a significantly higher cancellation rate, but similar pregnancy, implantation and delivery rates as patients with tubal infertility. Second, among the women with ovarian endometriosis, the women with a history of laparoscopic surgery for ovarian endometriomas prior to IVF and no visual endometriosis at ovum pick-up (n = 112) were compared with the non-operated women and visual endometriomas at ovum pick-up (n = 142). Patients who underwent ovarian surgery before IVF had significantly shorter period, lower antral follicle count and required higher gonadotropin doses than patients with non-operated endometriomas. The two groups of women with a previous or present ovarian endometriosis did, however, have similar pregnancy, implantation and live birth rates. In conclusion, ovarian endometriosis does not reduce IVF outcome compared with tubal factor. Furthermore, laparoscopic removal of endometriomas does not improve IVF results, but may cause a decrease of ovarian responsiveness to gonadotropins. PMID:21679474

The objective of this study was to present the initial operative experience of solo surgeon single-port laparoscopic surgery (SPLS) in the laparoscopic treatment of benign gynecologic diseases and to investigate its feasibility and surgical outcomes. Using a novel homemade laparoscope-anchored instrument system that consisted of a laparoscopic instrument attached to a laparoscope and a glove-wound retractor umbilical port, we performed solo surgeon SPLS in 13 patients between March 2011 and June 2012. Intraoperative complications and postoperative surgical outcomes were determined. The primary operative procedures performed were unilateral salpingo-oophorectomy (n = 5), unilateral salpingectomy (n = 2), adhesiolysis (n = 1), and laparoscopically assisted vaginal hysterectomy (n = 5). Additional surgical procedures included additional adhesiolysis (n = 4) and ovarian drilling (n = 1).The primary indications for surgery were benign ovarian tumors (n = 5), ectopic pregnancy (n = 2), pelvic adhesion (infertility) (n = 1), and benign uterine tumors (n = 5). Solo surgeon SPLS was successfully accomplished in all procedures without a laparoscopic assistant. There were no intraoperative or postoperative complications. Our laparoscope-anchored instrument system obviates the need for an additional laparoscopic assistant and enables SPLS to be performed by a solo surgeon. The findings show that with our system, solo surgeon SPLS is a feasible and safe alternative technique for the treatment of benign gynecologic diseases in properly selected patients.

Lim, Wei How; Roex, Alphonse J

2011-01-01

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

A 13-year-old, obese girl presented with acute abdominal pain with abdominal distension for a year. The physical examination revealed marked abdominal distension with a large well-circumscribed mass sized 13×20 cm. Her body mass index (BMI) was 37.8 kg/m2. An abdominal CT scan revealed a huge multiloculated cystic mass and a left adnexal mass. She had an abnormal fasting plasma glucose and low HDL-C. Laparotomy, right salpingooophorectomy, left cystectomy, lymph node biopsies and partial omentectomy were performed. The left ovary demonstrated multiple cystic follicles over the cortex. The histologic diagnosis was a mucinous cystadenoma of the right ovary and a matured cystic teratoma of the left ovary. Both obesity and polycystic ovary syndrome (PCOS) are associated with a greater risk of ovarian tumours, where PCOS could be either the cause or as a consequence of an ovarian tumour. We report an obese, perimenarchal girl with bilateral ovarian tumours coexistent with a polycystic ovary and the metabolic syndrome.

Purpose Endometriosis is associated with ovarian cancer, but the relation with endometrial cancer is unclear. Prior studies generally were retrospective and had potential limitations, including use of self-reported endometriosis, failure to account for delays between symptom onset and endometriosis diagnosis, and changes in risk factors post-endometriosis diagnosis. We evaluated whether these limitations obscured a weak association with endometrial cancer and the extent to which these limitations impacted associations with ovarian cancer. Methods Cox proportional hazards regression models were used to assess associations between endometriosis and cancer risk, evaluating the impacts of self-reported vs. laparoscopically-confirmed endometriosis, delayed diagnosis, and post-endometriosis diagnosis changes in risk factor exposures on relative risk estimates. Results Over 18 years of follow-up, we identified 228 ovarian and 166 endometrial cancers among 102,025 and 97,109 eligible women, respectively. Self-reported endometriosis was associated with ovarian cancer (relative risk (RR): 1.81; 95% confidence interval (CI): 1.26–2.58); this association was stronger for laparoscopically-confirmed endometriosis (HR: 2.14; 95% CI: 1.45–3.15). No association was observed with endometrial cancer (self-report RR: 0.78; 95% CI: 0.42–1.44; laparoscopic-confirmation RR: 0.76; 95% CI: 0.35–1.64). Accounting for diagnosis delays or post-endometriosis diagnosis changes in risk factors had little impact. Conclusions This study adds to the evidence that endometriosis is not strongly linked to endometrial cancer risk and that the association with ovarian cancer is robust to misclassification, diagnostic delay, and changes in exposures post-endometriosis diagnosis. Our analysis suggests that confounding and misclassification do not obscure a weak association for endometrial cancer risk, although our results should be replicated. PMID:28299512

This study aimed to compare two methods of treatment of infertility with gonadotropin with laparoscopic ovarian electrocauterization in patients with clomiphene citrate-resistant polycystic ovary syndrome (PCOS). A number of 104 nulipara patients with polycystic ovary syndrome, who were resistant to clomiphene citrate were randomly assigned to two groups. One group received gonadotropin; after the bleeding withdrawal and from the third day of the cycle, the injection of human menopausal gonadotropin (HMG) was started with 10 mg medroxy progesterone. The patients were followed with serial trans-vaginal sonographies. When the diameter of follicles reached to 18 mm, human chorionic gonadotropin (HCG) was prescribed. The other group was treated with laparoscopic ovarian electrocauterization under general anesthesia. If after 3 cycles, the anovulation was established with progesterone measurement, the clomiphene citrate was prescribed. Gonadotropin was administered, if the lack of ovulation persisted. No significant difference was documented between the two groups in terms of the obesity indexes, duration of infertility, age, sonographic and laboratory findings. In the gonadotropin group, 37 cases (71%) of pregnancy occurred. The rate of pregnancy was the same in the other group consisting of 18 cases treated by electrocautery, 9 cases with cautery + clomiphene, and 10 cases with clomiphene + cautery + gonadotropin. In the group treated with gonadotropin, there were 1 triple and 4 twins pregnancies. In the group treated with ovarian electrocautery, one twin pregnancy was observed. In the group treated with gonadotropin, 2 cases of ovarian hyperstimulation syndrome, 1 case of ectopic pregnancy and 6 cases of miscarriage occurred; the corresponding figure in the ovarian electrocautery group consisted of 5 cases of miscarriage. Our findings suggest that ovarian electrocauterization is an appropriate method with good efficacy and low complication rate for infertility treatment of women with clomiphene citrate-resistant polycystic ovary syndrome.

Impact of laparoscopic ovarian drilling on serum anti-mullerian hormone levels in patients with anovulatory Polycystic Ovarian syndrome.

Anti-mullerian hormone (AMH) is a marker of the activity of recruitable ovarian follicles. It is useful in the prediction of ovarian reserve. Women with polycystic ovarian syndrome (PCOS) have elevated circulating and intrafollicular AMH levels. Laparoscopic ovarian drilling (LOD) in patients with PCOS destroys ovarian androgen-producing tissue and reduces their peripheral conversion to estrogens. Identifying factors that determine the response of patients with PCOS to LOD will help in selecting the patients who would likely benefit from this treatment. AMH is one such marker that can predict the response to LOD. To evaluate the effect of LOD on serum AMH levels among PCOS responders and non-responders and the usefulness of AMH as a tool in predicting the response to LOD, and to whether there was loss of ovarian function after LOD. This is a prospective cohort study including 30 clomiphene-resistant women with anovulatory PCOS undergoing LOD. Statistical analysis was performed to evaluate the effect of LOD on serum levels of AMH on these women. A significant fall in the levels of AMH was observed after LOD in both responders and non-responders (p<0.001). Women with AMH >8.3 ng/mL showed a significantly lower ovulation rate (33.3%). LOD was not associated with a risk of diminished ovarian reserve. LOD is an effective first-line treatment for women with PCOS who are clomiphene resistant. LOD has no negative effect on ovarian reserve. AMH is a useful marker in predicting the outcome of LOD.

• 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.

Does unilateral volume-adjusted laparoscopic diathermy increase the chances of ovulation in women with polycystic ovary syndrome (PCOS)? Although unilateral laparoscopic ovarian drilling (ULOD) using adjusted thermal doses was more efficient than bilateral laparoscopic ovarian drilling (BLOD) using fixed doses, the chances of ovulation were improved in patients irrespective of the technique used. The adjustment of the thermal dose to ovarian volume in BLOD increases ovulation and pregnancy rates compared with fixed-dose treatment, but BLOD causes the formation of adhesions, particularly on the left ovary, and increases the risk of damage to ovarian tissue. In contrast, ULOD with a fixed thermal dose minimizes the risk of ovarian tissue damage, and can increase the activity in both right and left ovaries, although this varies in humans and in other species. This prospective, longitudinal, study, between September 2009 and January 2013, included 96 infertile women with PCOS who were unresponsive to clomiphene citrate treatment and had underwent either ULOD or BLOD. After surgery, the groups were followed up for 6 months to assess ovulatory response. Patients were assigned to two groups; one group underwent laparoscopic ovarian drilling of the right ovary alone, while both ovaries were treated in the second group. The ULOD group (n = 49) received thermal doses adjusted to the volume of the right ovary (60 J/cm³). The BLOD group (n = 47) received fixed doses of 600 J per ovary, regardless of its volume. The two treatment groups were matched by the number of participants, age and baseline parameters. The ovulation rate during the first menstrual cycle after LOD was significantly higher in the ULOD group than in the BLOD group [73 versus 49%; absolute risk reduction (ARR), -0.25; 95% confidence interval (CI), -0.44 to -0.03; P = 0.014]. Treatment with ULOD on the right ovary significantly increased the chances of ovulation in patients with a larger right ovary compared with those who had a smaller right ovary (100 versus 36%; ARR, -0.64; 95% CI, -0.84 to -0.37; P = 0.004). Interestingly, the chances of ovulation were also significantly higher in patients in the BLOD group who had a larger right ovary compared with those who had a smaller right ovary (88 versus 33%; ARR, -0.55; 95% CI, -0.73 to -0.28; P = 0.002). The pregnancy rate was also significantly higher in patients with a larger right ovary compared with those with a smaller right ovary, regardless of the treatment group. The 6-month follow-up was too short to demonstrate any long-term differences in the ovulation rates. Future research should therefore extend the follow-up beyond 6 months. Another limitation is that ULOD was used to treat only the right ovary. Future studies should investigate whether ULOD treatment of the larger ovary, whether left or right, would significantly increase the ovulation rate. This study represents an advance in the determination of the optimal laparoscopic treatment for women with PCOS, as it was shown that improved results can be achieved using less thermal energy in volume-adjusted ULOD.

Objective Investigation of initial 51 cases of single port access (SPA) laparoscopic surgery for large adnexal tumors and evaluation of safety and feasibility of the surgical technique. Methods We retrospectively reviewed the medical records of the first 51 patients who received SPA laparoscopic surgery for large adnexal tumors greater than 10 cm, from July 2010 to February 2015. Results SPA adnexal surgeries were successfully completed in 51 patients (100%). The mean age, body mass index of the patients were 43.1 years and 22.83 kg/m2, respectively. The median operative time, median blood loss were 73.5 (range, 20 to 185) minutes, 54 (range, 5 to 500) mL, and the median tumor diameter was 13.6 (range, 10 to 30) cm. The procedures included bilateral salpingo-oophorectomy (n=18, 36.0%), unilateral salpingo-oophorectomy (n=14, 27.45%), and paratubal cystectomy (n=1, 1.96%). There were no cases of malignancy and none were insertion of additional ports or conversion to laparotomy. The cases with intraoperative spillage were 3 (5.88%) and benign cystic tumors. No other intraoperative and postoperative complications were observed during hospital days and 6-weeks follow-up period after discharge. Conclusion Our results suggest that SPA laparoscopic surgery for large adnexal tumors may be a safe and feasible alternative to conventional laparoscopic surgery. PMID:28217669

To report a series of urinary tract injuries resultant of laparoscopic or robotic procedures performed for a gynecologic indication. We identified 16 patients with urinary tract fistulas after laparoscopic or robotic gynecologic procedures between 2009 and 2012. We extracted demographic data and prior surgical data as well as reviewed our management of each case. Thirteen subjects had undergone robotic procedures, 2 traditional laparoscopies, and a single-port laparoscopy with time to presentation from 2 days to 9 months postoperatively. Seven patients presented with vesicovaginal fistulas (43%), of which one healed spontaneously. Eight patients had ureterovaginal fistulas. Two patients (25%) were managed with ureteroneocystotomy, 2 patients (25%) were managed with Boari flap, and 4 patients (50%) were managed with double-J stent placement. One patient had a vesicocervical fistula managed via trachelectomy and partial cystectomy. The authors have seen an increase in referrals for urinary tract fistulas in minimally invasive surgery. It is imperative to investigate the effect of a steep learning curve, unfamiliarity with new energy sources, or poor patient selection as contributing factors.

Hysterectomy is the most common gynecological operation after Caesarean section and the laparoscopic access to uterus removal is one of the contemporary methods showing slow but steady growth in time. In reference to indications and contraindications for laparoscopic hysterectomy, the following directions emerge as controversial: malignant gynecological tumors, uterus size, and high body mass index. Laparoscopic hysterectomy can be taken into consideration at the first stage of endometrial, cervical and ovarian cancer. If there is doubt about an uterus sarcoma and a laparoscopic access is accomplished, a conversion to abdominal hysterectomy must be done. Obesity and big uteri are not a contrarindication for that minimally-invasive access. Today, laparoscopic hysterectomy is a reasonable alternative to total abdominal and vaginal hysterectomy.

Although lobular carcinomas metastasize primarily to lymph nodes, bone, lung and liver, they can also spread to the gastrointestinal tract, peritoneum and gynecologic organs. We report a case of intraperitoneal carcinomatosis of a lobular breast carcinoma that metastasized primarily to the peritoneum, with a subsequent abdominal wall invasion at the trocar site following laparoscopic surgery for the exclusion of an ovarian carcinoma. Port-site metastases (PSM) have occurred after laparoscopic surgery for endometrial, fallopian tube, ovarian, and cervical cancers. This is the first report of PSM of a lobular breast carcinoma primarily metastasized to the abdominal cavity. Every surgeon should be aware of the metastatic pattern of breast cancer, especially in relation to its histological subtypes. This case report emphasizes that PSM can occur in various kinds of gynecologic tumors, including breast cancer.

Atıcı A, Yılmaz E, Karaman A, Apaydın S, Afşarlar ÇE. Tuba-ovarian auto-amputation caused by ovarian teratoma in an adolescent girl. Turk J Pediatr 2017; 59: 90-92. Ovarian auto-amputation is an extremely rare condition commonly encountered in the perinatal period. Spontaneous or secondary torsion of the ovary caused by an ovarian lesion may result in infarction and subsequent auto-amputation of the ovary. This paper demonstrates a case that underwent laparoscopic appendectomy with an incidental calcified auto-amputated right ovary. A 16-year-old adolescent girl was admitted to our department with a history of one-day abdominal pain. Physical examination of the patient revealed abdominal tenderness and rigidity on right lower quadrant. Her white blood cell count was 11x103/mL, and C-reactive protein was 69 mg/L. The patient underwent a laparoscopic appendectomy with a provisional diagnosis of acute appendicitis, and further exploration revealed a 2x2 cm white ovoid mass floating freely in the pelvis. The left ovary was clearly identified in its usual localization, but the right tuba was blindly ending without any fimbria or ovary. Postoperative course of the patient was uneventful, and she was discharged on postoperative day 2. The histopathological examination revealed a necrotic calcified ovarian teratoma. Auto-amputated ovary is a rare occasion mostly encountered during perinatal period, and it may be unilateral or bilateral. An auto-amputated ovarian mass may rarely be a teratoma although the most common cause of auto-amputation during perinatal and adolescent period is ovarian torsion due to an ovarian cyst.

To evaluate the cumulative recurrence rates of ovarian endometrioma among patients using a levonorgestrel-releasing intrauterine system (LNG-IUS) after conservative laparoscopic surgery. A retrospective review was conducted of premenopausal women who underwent conservative laparoscopic surgery for ovarian endometrioma and subsequent treatment with LNG-IUS at two gynecologic surgery centers in South Korea between January 1, 2007, and September 30, 2014. Eligible patients had no residual ovarian lesions before LNG-IUS insertion, underwent insertion within 12 months of primary surgery, and were followed up for at least 6 months afterwards. Recurrence was defined as a cystic mass (≥2 cm in diameter) detected by transvaginal ultrasonography. Overall, 61 patients were included. The mean duration of follow-up was 42.9 ± 22.0 months (range 8-98). Recurrence of ovarian endometrioma was detected among 7 (11%) of the patients. On Kaplan-Meier analysis, the cumulative recurrence rates were 4.0%, 6.3%, and 25.5% at 24, 36, and 60 months after surgery, respectively. In multivariate analysis, nulliparity at surgery was the only risk factor for recurrence (hazard ratio 5.892, 95% confidence interval 1.139-30.484; P=0.034). Long-term maintenance therapy with LNG-IUS after conservative surgery might be a treatment option to consider to prevent ovarian endometrioma recurrence among premenopausal women.

Endometrial stromal sarcoma diagnosed after uterine morcellation in laparoscopic supracervical hysterectomy.

PubMed

Della Badia, Carl; Karini, Homa

2010-01-01

Endometrial stromal sarcoma is a rare uterine cancer with no reliable method for preoperative diagnosis. A 30-year-old parous woman underwent laparoscopic supracervical hysterectomy because of a leiomyoma. The uterus was removed from the abdominal cavity with an electric morcellator with a spinning blade. The pathology report revealed low-grade endometrial stromal sarcoma. Two months after the initial surgery, a second laparoscopic procedure was performed. The final pathology report confirmed low-grade endometrial stromal sarcoma involving the ovary, fallopian tube, and ovarian artery. It was concluded that morcellation of leiomyomas at laparoscopic supracervical hysterectomy may potentially increase metastasis if the tumor is a sarcoma. Copyright © 2010 AAGL.

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.

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.

Fertility-sparing surgery (FSS) is becoming an important technique in the surgical management of young women with early-stage epithelial ovarian cancer (EOC). We retrospectively evaluated the outcome of laparoscopic FSS in presumed clinically early-stage EOC. We retrospectively searched databases of patients who received laparoscopic FSS for EOC between January 1999 and December 2012 at Samsung Medical Center. Women aged ≤40 years were included. The perioperative, oncological, and obstetric outcomes of these patients were evaluated. A total of 18 patients was evaluated. The median age of the patients was 33.5 years (range, 14 to 40 years). The number of patients with clinically stage IA and IC was 6 (33.3%) and 12 (66.7%), respectively. There were 7 (38.9%), 5 (27.8%), 3 (16.7%), and 3 patients (16.7%) with mucinous, endometrioid, clear cell, and serous tumor types, respectively. Complete surgical staging to preserve the uterus and one ovary with adnexa was performed in 4 patients (22.2%). Two out of them were upstaged to The International Federation of Gynecology and Obstetrics stage IIIA1. During the median follow-up of 47.3 months (range, 11.5 to 195.3 months), there were no perioperative or long term surgical complications. Four women (22.2%) conceived after their respective ovarian cancer treatments. Three (16.7%) of them completed full-term delivery and one is expecting a baby. One patient had disease recurrence. No patient died of the disease. FSS in young patients with presumed clinically early-stage EOC is a challenging and cautious procedure. Further studies are urgent to determine the safety and feasibility of laparoscopic FSS in young patients with presumed clinically early-stage EOC.

Background and Objectives: The aim of this study was to compare the in vitro fertilization (IVF) outcomes of long gonadotropin-releasing hormone agonist (GnRH-a) and GnRH-antagonist (GnRH-ant) protocols in endometriosis patients who have undergone laparoscopic endometrioma resection surgery. To our knowledge, there is no study in the current literature that compares the effectiveness of long GnRH-a and GnRH-ant protocols in management of IVF cycles in endometriosis patients who underwent laparoscopic endometrioma resection surgery. Methods: Eighty-six patients with stage III to IV endometriosis who had undergone laparoscopic resection surgery for endometrioma were divided into 2 groups: those who had ovarian stimulation with a long GnRH-a protocol (n = 44), and those who had ovarian stimulation with a GnRH-ant protocol (n = 42). Results: The number of follicles on human chorionic gonadotropin injection day, duration of hyperstimulation, number of retrieved metaphase II oocytes, and total number of grade 1 embryos were statically significantly higher in the long GnRH-a protocol. There were no significant differences in positive β-human chorionic gonadotropin pregnancy rates (25% vs 21.4%; P = .269) and ongoing pregnancy rates per patient (20.5% vs 19.1%; P = .302) between the 2 protocols. Conclusions: Long GnRH-a and GnRH-ant protocols both present similar IVF outcomes in patients with endometriosis who have undergone laparoscopic endometrioma resection surgery. A long GnRH-a protocol may lead to a higher number of embryos that can be cryopreserved, providing the possibility of additional embryo transfers without having to go through the process of ovarian stimulation again.

To study the effects of laparoscopic ovarian cauterization and combination of long-acting GnRH agonist (GnRH-a) and oral contraceptive (OC) therapy on endocrine changes in women with clomiphene citrate (CC)- resistant polycystic ovary disease (PCOD). Prospective, randomized. University-based infertility clinic. Seventeen women with CC-resistant PCOD were included randomly in the study to either laparoscopic ovarian cautery or GnRH-a and OC therapy for 3 months. Serum concentrations of LH, FSH, androstenedione (A), T, and sex hormone-binding globulin (SHBG) were determined before each therapeutic approach and during the follicular phase of first menstrual cycle after the cessation of each treatment. The mean serum concentrations and the clinical profiles were similar in both groups. Both groups showed significant changes in LH, FSH, A, T, and SHBG compared with pretreatment levels. There were no significant differences in the final concentrations of LH, FSH, and A between the two study groups after each treatment, whereas T and SHBG levels were significantly different in the goserelin and OC group. The decrease in LH and increase in SHBG serum concentrations were greater in the goserelin and OC-treated women [-59% and + 5.9% versus - 70% and + 13.5%, respectively]. Although the SHBG concentration increased in both groups, the serum SHBG concentration of the goserelin and OC group was significantly higher than the other group. Both therapeutic modalities revealed similar effects on the endocrine profiles in women with CC-resistant PCOD. Considering the invasiveness, cost, and potential complications of laparoscopic ovarian cauterization, noninvasive medical treatment with GnRH-a and OC combination may be more effective in restoring the optimal follicular environment in women with PCOD.

Ovarian cancer is the fourth leading cause of cancer-related death among women in the United States. If diagnosed at an early stage, the 5-year survival rate is 94%, but drops to 68% for regional disease and 29% for distant metastasis; only 19% of all cases are diagnosed at the early, localized stage. Optical coherence tomography is a recently emerging non-destructive imaging technology, achieving high axial resolutions (10-20 microns) at imaging depths up to 2 mm. Previously, we studied OCT imaging in normal and diseased human ovary ex vivo to determine the features OCT is capable of resolving. Changes in collagen were suggested with several of the images that correlated with changes in collagen seen in malignancy. Areas of necrosis and blood vessels were also visualized using OCT, indicative of an underlying tissue abnormality. We recently developed a custom side-firing laparoscopic OCT (LOCT) probe fabricated specifically for in vivo laparoscopic imaging. The LOCT probe consists of a 38 mm diameter handpiece terminated in an 280 mm long, 4.6 mm diameter tip for insertion into the laparoscopic trocar and is capable of obtaining up to 9.5 mm image lengths at 10 micron axial resolution. In this study, we utilize the LOCT probe to image one or both ovaries of 20 patients undergoing laparotomy or transabdominal endoscopy and oophorectomy to determine if OCT is capable of identifying and/or differentiating normal and neoplastic ovary. To date, we have laparoscopically imaged the ovaries of ten patients successfully with no known complications.

The role of laparoscopy in staging of different gynaecological cancers.

Apart from cervical and vaginal cancers that are staged by clinical examination, most gynaecological cancers are staged surgically. Not only can pelvic and para-aortic lymphadenectomy offer accurate staging information that helps determine patients' prognosis and hence their treatment plan, but it may also provide a therapeutic effect under certain circumstances. In the past, such a procedure required a big laparotomy incision. With the advent of laparoscopic lighting and instrument, laparoscopic lymphadenectomy became popular since the late 1980s. Dargent et al. published the first report on laparoscopic staging in cervical cancers, and many studies then followed. To date, there are numerous case series and trials evaluating the efficacy and safety of laparoscopic surgery in managing gynaecological cancers. In general, compared with laparotomy, laparoscopic lymphadenectomy has less intraoperative blood loss and post-operative pain, fewer wound complications, shorter length of hospital stay and more speedy recovery. However, this is at the expense of longer operative time. The incidence of port-site metastasis is extremely low, although it may be higher in advanced ovarian cancer. Preliminary data showed that there was no significant effect on recurrence and survival, but long-term data are lacking. In this article, the roles of laparoscopy in staging of uterine, cervical and ovarian cancers, the three most common gynaecological cancers, will be reviewed. Novel technologies such as robot-assisted surgery, single-port surgery and sentinel node biopsy will also be discussed. Copyright © 2015 Elsevier Ltd. All rights reserved.

To review peri-procedural outcomes from a large, multi-institutional series of pediatric urology patients treated with laparaendoscopic single-site surgery (LESS) for major extirpative and reconstructive procedures. Consecutive LESS cases between January 2011 and May 2014 from three free-standing pediatric referral centers were reviewed. Data include age, sex, operative time, blood loss, length of stay, and complications according to the modified Clavien-Dindo classification. Hasson technique was used for peritoneal entry, GelPOINT advanced access platform was inserted, and standard 5mm laparoscopic instruments were used. Fifty-nine patients (median age 5 years, 4 months-17 years) met inclusion criteria: 29 nephrectomies, 9 nephroureterectomies, 3 bilateral nephrectomies, 5 heminephrectomies, 5 renal cyst decortications, 3 bilateral gonadectomies, 2 Malone antegrade continence enema, 2 calyceal diverticulectomy, and 1 ovarian detorsion with cystectomy. Median operative times for each case type were comparable to published experiences with traditional laparoscopy. Overall mean and median length of stay was 36.2 hours and 1 day, respectively. There were two complications: port site hernia requiring surgical repair (Clavien IIIb) and a superficial port site infection that resolved with antibiotics (Clavien II). Cosmetic outcomes were subjectively well received by patients and their parents. Operative time was significantly shorter between the first half of the experience and the second half (102 vs 70 minutes, P  <  .05). LESS approach can be broadly applied across many major extirpative and reconstructive procedures within pediatric urology. Our series advances our field's utilization of this technique and its safety. Copyright © 2016 Elsevier Inc. All rights reserved.

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.

Mature cystic teratomas are the most common ovarian neoplasm in adolescents. They are typically benign, however, malignant transformation rarely occurs. We report a low-grade astrocytoma arising from a mature cystic teratoma in an adolescent patient. The patient was a 12-year-old girl with an asymptomatic ovarian cyst and subsequent cystectomy. Final pathology identified a solid tumor with glial tissue within the cyst, reported as low-grade astrocytoma arising in a mature cystic teratoma. There are few data on astrocytomas in the gynecologic tract. Risk factors for malignant transformation in a mature cystic teratoma include increased age, postmenopausal status, elevated carcinoma antigen 125, and large tumor size. Interestingly, this patient had a history of partial trisomy 20, which has been associated with teratoma formation in a mouse model.

Ovarian steroid cell tumors are very rare but potentially life-threatening neoplasms. They represent less than 0.1% of all ovarian tumors, typically present in premenopausal women and frequently manifest with virilization. Signs of hyperandrogenism may appear in postmenopausal women due to tumorοus and non-tumorοus adrenal and ovarian causes as well due to the normal aging process. In any case, steroid cell tumor should be suspected in postmenopausal women who present with rapid progressive androgen excess symptoms. This report describes a case of a 67-year-old postmenopausal woman with signs of hyperandrogenism, where an ovarian steroid cell tumor was diagnosed and treated by laparoscopic bilateral salpingo-oophorectomy and synchronous hysterectomy.

Objective: To evaluate the efficacy of preemptive intravenous oxycodone in the patients undergoing laparoscopic resection of ovarian tumor. Methods: Sixty ASA I or II patients undergoing elective laparoscopic resection of ovarian tumor were randomly allocated to one of two groups: Group O (n=30) received intravenous oxycodone (0.1 mg·kg-1) 10 minutes before surgery over 2 minutes, and Group N (n=30) received an equivalent volume of normal saline. All patients received a standardized general anesthesia. MBP and HR at the time of arrival of the operating room (T1), 5 min before pneumoperitoneum (T2), 5 minutes (T3), 10 minutes (T4), and 15 minutes after pneumoperitoneum (T5), and VAS scores at postoperative 2, 4, 8, 12 and 24 hour were recorded. The tramadol consumption and side effects in 24 h after surgery were recorded. Results: VAS pain scores at 2, 4, 8 and 12 hour after operation were significantly lower in Group O (P<0.05). MBP and HR increased significantly due to pneumoperitoneum at T3, T4 and T5, compared with T1 and T2 within Group N, and were higher at T3, T4 and T5 in Group N than at the same time points in Group O. Tramadol consumption was statistically lower in Group O (P=0.0003). Conclusions: Preemptive intravenous oxycodone was an efficient and safe method to reduce intraoperative haemodynamic effect and postoperative pain. PMID:26101479

The use of transabdominal ultrasonography to assess the oestrous cycle has not been previously described in the African lion (Panthera leo). Twelve sexually mature lionesses and five female cubs had their reproductive organs assessed by transabdominal ultrasound. Ovarian findings were compared to laparoscopic findings while performing laparoscopic ovariectomy or salpingectomy. Vaginal cytology was performed and serum progesterone levels were determined. By combining all data the oestrous cycle stage of each lion was determined. One lion was far pregnant and was not operated on. In adults a uterine body could be seen ultrasonographically in 67% of lions while mural structures could be distinguished in 44% of lions. Five uterine horns could be seen in 3 lions. In 12 adults 10 ovaries were found of which eight had discernable follicles or luteal structures. During laparoscopy 12 active ovaries were seen with luteal structures seen in 11 ovaries and follicles in 2 ovaries. Using laparoscopy as the gold standard, ultrasonography had a sensitivity of 66% and specificity of 83% to detect ovarian reproductive activity. Two uterine cysts and a cluster of periovarian cysts were seen in three different lions. Three lions were pregnant, two were in oestrus, three in a luteal phase (dioestrus), and four were in anoestrus. Transabdominal ultrasound in combination with serum progesterone levels and vaginal cytology can be used to assess ovarian cyclical activity with reasonable accuracy in captive bred lions.

Laparotomy has become the preferred approach to the excision of large, complex abdominal cysts in the neonate. We describe a laparoscopic-assisted decapsulation of an antenatally diagnosed abdominal cyst that was noted on postnatal ultrasound scan to have a complex echo pattern. This limited procedure allows for accurate verification of the diagnosis, institution of appropriate therapy, and organ salvage. It represents a superior management option that obviates the significant complications associated with conservative management.

2018-03-01

Laparoscopic ovarian drilling (LOD) is still a controversial decision; due to the long term hazards; so short and long term predictors after the procedure should be taken in consideration. The aim of this work was to investigate the role of the serum level of tumor necrosis factor alpha (TNF-α) and other polycystic ovarian disease (PCOD) relevant clinical and biochemical factors as a predictor of spontaneous ovulation after laparoscopic ovarian drilling (LOD) in women with clomiphene citrate resistant polycystic ovarian disease (CCR-PCOD). It was a prospective research work, where 150 infertile women with CCR-PCOD had been recruited. TNF-α serum level, which is an inflammatory biomarker, was investigated in addition to other PCOD relevant clinical and biochemical parameters as possible predictors of successful spontaneous ovulation and subsequent pregnancy after LOD. Recruited women with higher preoperative levels of TNF-α, LH, and androstenedione had significantly higher rates of spontaneous ovulation within the first three months follow up after LOD, in contrast to obese women with BMI ≥ 25 kg/m2, long duration of infertility ≥3 years, marked biochemical hyperandrogenism (testosterone levels ≥4.5 nmol/L, free androgen index ≥15), and high insulin resistance (IR). Ninty five (95 = 63.3%) women in between women regularly menstruated (105 = 70%) had spontaneous ovulation, and of those spontaneously ovulated, 35(36.8%) women got pregnant spontaneously during the first 3 months follow up. Extended follow up for 12 months period revealed that 61 women got pregnant, with cumulative pregnancy rate of 58%. Logistic regression showed that the best cut-off values for spontaneous ovulation after LOD were 65.1 pg/ml, 11.5 IU/l, and 3.1 ng/ml and with a sensitivity of 91%, 88%, 55%, and with a specificity of 85%, 79%, 78%, for TNF-α, LH, androstenedione serum level respectively. TNF-α, LH, and Androstenedione could be considered as reliable predictors to depend on for recruiting the ideal women candidates with CCR-PCOD; to have the maximum benefits after LOD treatment option.

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.

Management strategies for ovulation induction in women with polycystic ovary syndrome and known clomifene citrate resistance.

PubMed

Palomba, Stefano; Falbo, Angela; Zullo, Fulvio

2009-12-01

Clomifene citrate is the first and the most used agent for inducing ovulation in patients affected by polycystic ovary syndrome (PCOS). About 60-85% of PCOS women ovulated under clomifene citrate, whereas the others were defined clomifene citrate-resistant. The purpose of the current review will be to describe treatment strategies to induce ovulation in infertile PCOS patients with clomifene citrate resistance. Clomifene citrate and metformin association are a valid option for inducing ovulation in clomifene citrate-resistant PCOS patients. Surgical ovulation induction by laparoscopic ovarian drilling should be reserved to well selected cases. Excellent preliminary results are obtained using new drug formulations, such as aromatase inhibitors. In clomifene citrate-resistant PCOS patients, clomifene citrate and metformin combination and laparoscopic ovarian drilling, in selected cases, should be considered before gonadotropin administration. The efficacy of the other treatments must be confirmed in future well designed studies.

Large Omental Cystic Lymphangioma Masquerading as Mucinous Ovarian Neoplasia in an 8-Year-Old Premenarchal Girl: The Findings from Diagnostic Imaging and Laparoscopic-Assisted Excision.

2017-12-01

Omental cystic lymphangioma is an extremely rare abdominal mass caused by congenital malformation. An 8-year-old premenarchal girl reported abdominal pain. Diagnostic imaging revealed a large multicystic mass measuring 22 cm in diameter, which occupied the entire abdominal cavity with ascites. Emergency laparoscopy revealed a ruptured large cystic mass originating from the greater omentum; this was followed by successful laparoscopic-assisted excision. The pathological diagnosis was omental cystic lymphangioma. The present findings show that omental cystic lymphangioma masquerading as mucinous ovarian neoplasia was a rare cause of acute abdominal events in a young girl. The present case shows that minimally invasive surgery can be a feasible option, which might achieve a favorable outcome in a young patient with an omental cystic lymphangioma.

A 10-year-old premenarchal girl was admitted to our hospital with moderate abdominal pain, although presenting no vomiting or abdominal rebound tenderness. A large abdominal mass was visible and palpable in the periumbilical and epigastric regions. Results of physical examination revealed that the general health status was satisfactory. Computed tomographic scan revealed a large, thin-walled cyst occupying nearly the entire peritoneal cavity. The other viscera were of normal aspect. A laparoscopic approach revealed a left ovarian cystic tumor that was twisted 360 degrees in conjunction with the uterine corpus with hemorrhagic infarction. A partial hysterectomy and a left salpingo-oophorectomy were carried out. The tumor was classified as mature cystic teratoma of the ovary accompanied by hemorrhagic necrosis, not only of the cyst but also of the left uterine tube and the uterine corpus.

Intrauterine autoamputation of the ovary is an extremely rare diagnosis in the pediatric population. The current literature is limited to contradictory recommendations, while a standard management protocol for autoamputated adnexa secondary to intrauterine ovarian torsion is yet to be established. We report 2 cases of auto-amputation of the ovary, leading to a free-floating intra-abdominal cyst in the newborn. Laparoscopic management was successful in both cases. Copyright © 2017 AAGL.

Kruschinski, Daniel; Homburg, Shirli

2005-01-01

The objective of this Chapter was to investigate the feasibility and outcome of gasless laparoscopy under regional anesthesia. A prospective evaluation of Lift-(gasless) laparoscopic procedures under regional anesthesia (Canadian Task Force classification II-1) was done at three endoscopic gynecology centers (franchise system of EndGyn(r)). Sixty-three patients with gynecological diseases comprised the cohort. All patients underwent Lift-laparoscopic surgery under regional anesthesia: 10 patients for diagnostic purposes, 17 for surgery of ovarian tumors, 14 to remove fibroids, and 22 for hysterectomies. All patients were operated without conversion to general anesthesia and without perioperative or anesthesiologic complications. Lift-laparoscopy under regional anesthesia can be recommended to all patients who desire laparoscopic intervention without general anesthesia. For elderly patients, those with cardiopulmonary risks, during pregnancy, or with contraindications for general anesthesia, Lift-laparoscopy under regional anesthesia should be the procedure of choice.

Current Status of Robot-Assisted Radical Cystectomy: What is the Real Benefit?

PubMed

Takenaka, Atsushi

2015-09-01

In recent years, robot-assisted radical cystectomy has received attention worldwide as a useful procedure that helps to overcome the limitations of open radical cystectomy. We compared the surgical technique, perioperative and oncological outcomes, and learning curve of robot-assisted radical cystectomy with those of open radical cystectomy. The indications for robot-assisted radical cystectomy are identical to those of open radical cystectomy. Relative contraindications are due to patient positioning in the Trendelenburg position for long periods. Urinary diversion is performed either extracorporeally with a small skin incision or intracorporeally with a totally robotic-assisted maneuver. Accordingly, robot-assisted radical cystectomy can be performed safely with an acceptable operative time, little blood loss, and low transfusion rates. The lymph node yield and positive surgical margin rate were not significantly different between robot-assisted radical cystectomy and open radical cystectomy. The survival rates after robot-assisted radical cystectomy are estimated to be similar to that after open radical cystectomy. However, the recurrence pattern is different between robot-assisted radical cystectomy and open radical cystectomy, i.e., extrapelvic lymph node recurrence and peritoneal carcinomatosis were more frequently found in patients who underwent robot-assisted radical cystectomy than in those who underwent open radical cystectomy. Further validation is necessary to prove the feasibility of oncological control. A steep learning curve is one of the benefits of the new technique. The experience of only 50 robot-assisted radical prostatectomies is a minimum requirement for performing feasible robot-assisted radical cystectomy, and surgeons who have performed only 30 surgeries can reach an acceptable level of quality for robot-assisted radical cystectomy.

Port-Site Metastases and Chimney Effect of B-Ultrasound-Guided and Laparoscopically-Assisted Hyperthermic Intraperitoneal Perfusion Chemotherapy

2017-01-01

Purpose CO2 leakage along the trocar (chimney effect) has been proposed to be an important factor underlying port-site metastasis after laparoscopic surgery. This study aimed to test this hypothesis by comparing the incidence of port-site metastasis between B-ultrasound-guided and laparoscopically-assisted hyperthermic intraperitoneal perfusion chemotherapy (HIPPC). Materials and Methods Sixty-two patients with malignant ascites induced by gastrointestinal or ovarian cancer were divided into two groups to receive either B-ultrasound-guided or laparoscopically-assisted HIPPC. Clinical efficacy was assessed from the objective remission rate (ORR), the Karnofsky Performance Status (KPS) score, and overall survival. The incidence of port-site metastasis was compared between the two groups. Results Patients in the B-ultrasound (n=32) and laparoscopy (n=30) groups were comparable in terms of age, sex, primary disease type, volume of ascites, and free cancer cell (FCC)-positive ascites. After HIPPC, there were no significant differences between the B-ultrasound and laparoscopy groups in the KPS score change, ORR, and median survival time. The incidence of port-site metastasis after HIPPC was not significantly different between the B-ultrasound (3 of 32, 9.36%) and laparoscopy (3 of 30, 10%) groups, but significantly different among pancreatic, gastric, ovarian, and colorectal cancer (33.33, 15.79, 10.00, and 0.00%, p<0.001). Conclusion The chimney effect may not be the key reason for port-site metastasis after laparoscopy. Other factors may play a role, including the local microenvironment at the trocar site and the delivery of viable FCCs (from the tumor or malignant ascites) to the trauma site during laparoscopic surgery.

OBJECTIVE To assess rates of intraoperative complications and conversion to laparotomy associated with supervised veterinary students performing laparoscopic ovariectomy in dogs. DESIGN Retrospective case series. ANIMALS 161 female shelter dogs for which elective laparoscopic ovariectomy had been performed by supervised senior (fourth-year) veterinary students from 2010 through 2014. PROCEDURES Medical records of all dogs were reviewed and data collected regarding duration of surgery, surgical complications and other characteristics, and whether conversion to laparotomy was required. RESULTS Laparoscopic ovariectomy was performed with a 2-cannula technique and a 10-mm vessel-sealing device for hemostasis in all dogs. A Veress needle was used for initial insufflation in 144 (89.4%) dogs; method of insufflation was not reported for the remaining 17 (10.6%) dogs. Mean ± SD duration of surgery was 114.90 ± 33.40 minutes. Surgical complications, all classified as minor blood loss, occurred in 24 (14.9%) dogs. These included splenic puncture during insertion of the Veress needle (n = 20 [12.4%]) and minor bleeding from the ovarian pedicle (4 [2.5%]). Splenic puncture required no intervention, and ovarian pedicle bleeding required application of the vessel-sealing device an additional time to control the bleeding. Two ovaries were dropped in the abdominal cavity at the time of removal. Both were retrieved without complication. Conversion to laparotomy was not required for any dog. All dogs were discharged from the hospital within 24 hours after surgery. CONCLUSIONS AND CLINICAL RELEVANCE Laparoscopic ovariectomy in dogs was performed safely by closely supervised novice surgeons, with only minor intraoperative complications encountered and no need for conversion to laparotomy.

Prevalence and management of urinary tract endometriosis: a clinical case series.

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.

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.

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

Minimally invasive surgery has been the trend in various specialties and continues to evolve as new technology develops. The development of robotic surgery in gynecology remains in its infancy. The present study reports the first descriptive series of robotic surgery in complicated gynecologic diseases in Taiwan. From March 2009 to February 2011, the records of patients undergoing robotic surgery using the da Vinci Surgical System were reviewed for patient demographics, indications, operative time, hospital stay, conversion to laparotomy, and complications. Sixty cases were reviewed in the present study. Forty-nine patients had benign gynecologic diseases, and 11 patients had malignancies. These robot-assisted laparoscopic procedures include nine hysterectomy, 15 subtotal hysterectomy, 13 myomectomy, eight staging operation, two radical hysterectomy, five ovarian cystectomy, one bilateral salpingo-oophorectomy and myomectomy, two resections of deep pelvic endometriosis, one pelvic adhesiolysis, three sacrocolpopexy and one tuboplasty. Thirty-three patients had prior pelvic surgery, and one had a history of pelvic radiotherapy. Adhesiolysis was necessary in 38 patients to complete the whole operation. Robotic myomectomy was easily accomplished in patients with huge uterus or multiple myomas. The suturing of myometrium or cervical stump after ligation of the uterine arteries minimized the blood loss. In addition, it was much easier to dissect severe pelvic adhesions. The dissection of para-aortic lymph nodes can be easily accomplished. All these surgeries were performed smoothly without ureteral, bladder or bowel injury. The present analyses include various complicated gynecologic conditions, which make the estimation of the effectiveness of robotic surgery in each situation individually not appropriate. However, our experiences do show that robotic surgery is feasible and safe for patients with complicated gynecologic diseases. Copyright © 2012. Published by Elsevier B.V.

2015-05-01

To compare the therapeutic effects of metformin (Met) and laparoscopic ovarian drilling (LOD) in clomiphene and insulin-resistant patients with polycystic ovary syndrome (CIRPCOS). A total of 110 patients were randomly divided into two groups. One group was administered Met (n = 55), while the other group underwent LOD (n = 55). Rates of ovulation, pregnancy, and abortion were compared between both groups. Rates of normal menstruation, ovulation, and pregnancy in the LOD group were higher than in the Met group: 76.4% (42/55) vs. 58.2% (32/55), P < 0.04; 50.8% (11/258) vs. 33.5% (94/281), P < 0.001; 38.2% (21/55) vs. 20.0% (11/55), P < 0.03. The difference in the early abortion rate between both groups was not statistically significant. Although Met can significantly improve a patient's insulin resistance, we found that in patients diagnosed with CIRCPOS, LOD can be much more effective in improving rates of normal menstruation, ovulation, and pregnancy.

Ovarian cancer is the fourth leading cause of cancer-related death among women. If diagnosed at early stages, 5-year survival rate is 94%, but drops to 68% for regional disease and 29% for distant metastasis; only 19% of cases are diagnosed at early, localized stages. Optical coherence tomography is a recently emerging non-destructive imaging technology, achieving high axial resolutions (10-20 µm) at imaging depths up to 2 mm. Previously, we studied OCT in normal and diseased human ovary ex vivo. Changes in collagen were suggested with several images that correlated with changes in collagen seen in malignancy. Areas of necrosis and blood vessels were also visualized using OCT, indicative of an underlying tissue abnormality. We recently developed a custom side-firing laparoscopic OCT (LOCT) probe fabricated for in vivo imaging. The LOCT probe, consisting of a 38 mm diameter handpiece terminated in a 280 mm long, 4.6 mm diameter tip for insertion into the laparoscopic trocar, is capable of obtaining up to 9.5 mm image lengths at 10 µm axial resolution. In this pilot study, we utilize the LOCT probe to image one or both ovaries of 17 patients undergoing laparotomy or transabdominal endoscopy and oophorectomy to determine if OCT is capable of differentiating normal and neoplastic ovary. We have laparoscopically imaged the ovaries of seventeen patients with no known complications. Initial data evaluation reveals qualitative distinguishability between the features of undiseased post-menopausal ovary and the cystic, non-homogenous appearance of neoplastic ovary such as serous cystadenoma and endometroid adenocarcinoma.

Regionalization of care and travel distance may result in unintended consequences for complex surgery such as cystectomy. Our objective was to evaluate effect of differential distance on cystectomy receipt among patients with muscle-invasive bladder cancer (MIBC) and investigate the association between travel distance and cystectomy outcomes such as readmission. Using a linked data resource combining the NC Central Cancer Registry with claims data from Medicare, Medicaid, and private insurance plans, we included 736 patients with MIBC and 1,082 who underwent cystectomy. To evaluate access, differential distance was calculated as the difference between the nearest urologist and nearest cystectomy provider. To assess outcomes, logistic regression was used to evaluate rehospitalization and major complications, and Cox proportional hazards model for survival analysis. To evaluate access and outcomes, 736 patients with MIBC and 1,082 patients undergoing cystectomy were evaluated, respectively. Overall, 29% (211 of 736) with MIBC underwent cystectomy. Differential distance was not a predictor of cystectomy receipt (odds ratio = 1.0; 95% CI: 1.00, 1.01). Among patients undergoing cystectomy, travel distance from cystectomy provider was not a significant predictor of 30- or 31 to 90day readmissions (odds ratio = 1.0; 95% CI: 1.00, 1.00) although patients who lived further from their cystectomy provider were more likely to be readmitted to a nonindex hospital (P<0.001) when controlling for other factors. Although travel distance did not have a significant effect on overall survival, patients readmitted between 31 to 90days had worse overall survival (P<0.0001). The additional distance needed to reach a cystectomy provider did not predict receipt of surgery for MIBC. Furthermore, travel distance from cystectomy provider was not a significant predictor for subsequent readmission after cystectomy and did not affect overall survival. Copyright © 2018 Elsevier Inc.

2015-04-01

Despite the large number of analytical reports regarding the learning curve in the transition from open to robot-assisted radical prostatectomy (RARP), few comparative results with laparoscopic radical prostatectomy (LRP) have been reported. Thus, we evaluated operative and postoperative outcomes in RARP versus 100 simultaneously performed LRPs. A single surgeon had performed more than 1,000 laparoscopic operations, including 415 cases of radical nephrectomy, 85 radical cystectomies, 369 radical prostatectomies, and treatment of 212 other urological tumors, since 2009. We evaluated operative (operation time, intraoperative transfusion, complications, hospital stay, margin status, pathological stage, Gleason score) and postoperative (continence and erectile function) parameters in initial cases of RARP without tutoring compared with 100 recently performed LRPs. Mean operation time and length of hospital stay for RARP and LRP were 145.5±43.6 minutes and 118.1±39.1 minutes, and 6.4±0.9 days and 6.6±1.1 days, respectively (p=0.003 and p=0.721). After 17 cases, the mean operation time for RARP was similar to LRP (less than 2 hours). Positive surgical margins in localized cancer were seen in 11.1% and 8.9% of cases in RARP and LRP, respectively (p=0.733). At postoperative 3 months, sexual intercourse was reported in 14.0% and 12.0%, and pad-free continence in 96.0% and 81.0% in patients with RARP and LRP, respectively (p=0.796 and p=0.012). Previous large-volume experience of LRPs may shorten the learning curve for RARP in terms of oncological outcome. Additionally, previous experience with laparoscopy may improve the functional outcomes of RARP.

To compare conventional laparoscopic ovarian drilling (LOD) with transvaginal hydrolaparoscopy (THL) ovarian drilling in terms of ovarian adhesion formation, evaluated using office THL during follow-up in CC-resistant anovulatory patients affected by PCOS. Prospective randomized study on 246 CC-resistant women with PCOS. The patients enrolled were divided into two groups, 123 were scheduled to undergo LOD and 123 to undergo THL ovarian drilling. Six months after the procedure all patients were offered office transvaginal hydrolaparoscopy (THL) follow-up, under local anesthesia to evaluate adhesion formation. Duration of the procedure was significantly shorter in the THL group in comparison with LOD group (p < 0.0001). No intra- or post-operative complication was observed in any of the patients in both groups. Post-operative THL follow-up after 6 months showed that 15 (15.5 %) patients in the THL group and 73 (70.2 %) in the LOD group showed the presence of ovarian adhesion. This difference was highly significant with a p value <0.0001 and a relative risk of 0.22 [95 % IC 0.133-0.350]. This study seems to indicate that THL ovarian drilling may reduce the risk of ovarian adhesion formation and could be used as a safe and effective option to reduce ovarian adhesion formation in patients undergoing ovarian drilling.

Laparoscopic Management of Sclerosing Stromal Tumors of the Ovary Combined with Ectopic Pregnancy.

2015-01-01

Like other stromal-derived gynecological tumors, a sclerosing stromal tumor of the ovary (SSTO) is a rare benign tumor that is difficult to distinguish from a malignant ovarian tumor in clinical practice. An SSTO is routinely treated with laparotomy. Here, we present two extremely rare cases of SSTO with contralateral and ipsilateral tubal pregnancies, in which laparoscopic surgery was performed to remove the tumors. After surgery, one patient (case 1) became pregnant twice within 29 months, and the other patient (case 2) did not become pregnant within 6 months postoperatively. These two cases suggest that laparoscopic management is not only useful in treating SSTO and complicating diseases, but it may also help to reduce unnecessary surgical injury to the ovary. © 2015 S.

This study was conducted to evaluate the feasibility and therapeutic safety of laparoendoscopic single-site ovariectomy (LESS-OVE) and 3-portal laparoscopic ovariectomy (Lap-OVE) in dogs. Ten female mixed breed dogs were included in the study. Dogs were divided into group 1 (LESS-OVE; n = 5) and group 2 (Lap-OVE; n = 5). All procedures were performed by laparoscopic-skilled surgeons, and the anesthetic protocol was the same for all patients. In both groups, the ovarian vascular pedicle and ligaments were transected using a bipolar vessel sealer/divider device. The mean total surgical time was slightly longer in LESS-OVE (36.6 ± 3.5 min) than Lap-OVE (32.0 ± 3.0 min); however, the differences were not significant. Perioperative complications were not reported in any group. Both laparoscopic techniques were shown to be equally feasible and safe for patients. However, surgeons found LESS-OVE to require more skill than Lap-OVE. Therefore, additional studies should be conducted to evaluate this novel approach in clinical veterinary practice, and a proper laparoscopic training program for veterinary surgeons should be developed.

To investigate the feasibility of using high-intensity focused ultrasound (HIFU), under dual-mode ultrasound arrays (DMUAs) guidance, to induce localized thermal damage inside ovaries without damage to the ovarian surface. Laboratory feasibility study. University-based laboratory. Ex vivo canine and bovine ovaries. DMUA-guided HIFU. Detection of ovarian damage by ultrasound imaging, gross pathology, and histology. It is feasible to induce localized thermal damage inside ovaries without damage to the ovarian surface. DMUA provided sensitive imaging feedback regarding the anatomy of the treated ovaries and the ablation process. Different ablation protocols were tested, and thermal damage within the treated ovaries was histologically characterized. The absence of damage to the ovarian surface may eliminate many of the complications linked to current laparoscopic ovarian drilling (LOD) techniques. HIFU may be used as a less traumatic tool to perform LOD. Copyright © 2014 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.

The introduction of laparoscopic ovarian drilling (LOD) by Gjönnaess in 1984 as a substitute for ovarian wedge resection created opportunities for extensive research given its worldwide application for ovulation induction in women with polycystic ovary syndrome (PCOS). To critically evaluate and summarize the current body of literature regarding the role of LOD for the management of PCOS entailing its different preoperative, operative and postoperative aspects. In addition, long-term efficacy, cost-effectiveness, patient preference and health-related quality of life issues will be evaluated together with other available alternatives of ovulation induction treatments. A PubMed search was conducted looking for the different trials, reviews and various guidelines relating to the role of LOD in the management of PCOS. LOD whether unilateral or bilateral is a beneficial second-line treatment in infertile women with clomiphene citrate (CC)-resistant PCOS. It is as effective as gonadotrophin treatment but without the risk of multiple pregnancy or ovarian hyperstimulation and does not require intensive monitoring. Increased responsiveness of the ovary to CC especially in patients who remain anovulatory following LOD is another advantage. Recent evidence suggests that relatively novel oral methods of ovulation induction, e.g. CC plus metformin, CC plus tamoxifen, rosiglitazone plus CC and aromatase inhibitors represent a successful alternative to LOD in CC-resistant PCOS. Meanwhile current evidence does not support LOD as a first-line approach in PCOS-related anovulation or before IVF. LOD is currently recommended as a successful and economical second-line treatment for ovulation induction in women with CC-resistant PCOS.

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

We describe a Gorlin syndrome (GS) case with two different second hit mutations of PTCH1, one in a keratocystic odontogenic tumor (KCOT) and the other in an ovarian leiomyoma. GS is a rare genetic condition manifesting as multiple basal cell nevi associated with other features such as medulloblastomas, skeletal abnormalities, and ovarian fibromas. A 21-year-old Japanese woman with a history of two KCOTs was diagnosed with GS according to clinical criteria. A PTCH1 mutation, c.1427del T, was detected in peripheral blood. A novel PTCH1 mutation, c.264_265insAATA, had been found in the maxillary KCOT as a second hit mutation. More recently, the ovarian tumor was detected during a gynecological examination. Laparoscopic adnexectomy was performed, and the pathological diagnosis of the ovarian tumor was leiomyoma. Interestingly, another novel mutation, loss of heterozygosity spanning from 9q22.32 to 9q31.2, including PTCH1 and 89 other genes, was detected in this ovarian tumor, providing evidence of a second hit mutation. This is the first report describing a GS-associated ovarian tumor carrying a second hit in the PTCH1 region. We anticipate that accumulation of more cases will clarify the importance of second hit mutations in ovarian tumor formation in GS. © 2016 Wiley Periodicals, Inc.

Role of Ovarian Transposition Based on the Dosimetric Effects of Craniospinal Irradiation on the Ovaries: A Case Report

2007-10-01

In this study, we present a case of laparoscopic ovarian transposition to preserve ovarian function in an adult female patient treated with craniospinal irradiation for standard risk medulloblastoma. The prescribed dose to the craniospinal axis was 2340 cGy at 180 cGy per fraction and was delivered with 6-MV photons. Before ovarian transposition, magnetic resonance imaging (MRI) of the pelvis was obtained for localization of the ovaries and was registered with the planning computed tomography (CT) scan. Surgical clips allowed for CT localization of the ovaries after transposition. As a result of ovarian transposition, mean and maximum radiation doses decreased frommore » 983 to 68 cGy and 1624 to 84 cGy for the left ovary and from 166 to 87 cGy and 723 to 103 cGy for the right ovary, respectively. Review of the literature indicates that such radiation doses are below the threshold that causes ovarian dysfunction and infertility. We conclude that ovarian localization with an MRI of the pelvis can be offered to females undergoing craniospinal irradiation. Transposition of the ovaries provides an option to preserve ovarian function in cases where the ovaries would otherwise be included within the radiation field.« less

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 investigate whether laparoscopic excision of ovarian endometriomas pretreated with operation by gynecologists or reproductive surgeons exerts different effects on in vitro fertilization-intracytoplasmic sperm injection results. Retrospective case control study. Relevant information was collected from the electronic records of women who underwent IVF/ICSI from 01/01/2013 to 30/12/2015 in our unit. The study group consisted of 35 women who previously had laparoscopic endometrioma excision by reproductive surgeons in our unit; the control group included 36 patients who underwent surgery for endometriomas by gynecologists in our hospital. There were slightly higher numbers of AFC and higher pregnancy rate in the study group, although differences did not reach statistical significance. For patients over 35 years old, there were more oocyte retrieved, mature oocytes and two pronucei (2PN) in the study group than the control group although observed differences did not reach statistical significance. Electrocautery is more deleterious on ovarian reserve than hemostatic suture. In procedure of patients who wish to conceive, surgeons should use hemostatic suturing technique preferentially.

We summarized the whole contents presented at the workshop. Regarding cervical cancer screening in Asia, particularly in low resource settings, and an update on human papillomavirus (HPV) vaccination was described for prevention and radical surgery overview, fertility sparing and less radical surgery, nerve sparing radical surgery and primary chemoradiotherapy in locally advanced cervical cancer, were discussed for management. As to surgical techniques, nerve sparing radical hysterectomy, optimal staging in early ovarian cancer, laparoscopic radical hysterectomy, one-port surgery and robotic surgery were introduced. After three topics of endometrial cancer, laparoscopic surgery versus open surgery, role of lymphadenectomy and fertility sparing treatment, there was a special additional time for clinical trials in Asia. Finally, chemotherapy including neo-adjuvant chemotherapy, optimal surgical management, and the basis of targeted therapy in ovarian cancer were presented. PMID:20922136

To describe laparoscopic ovariectomy and salpingectomy in the cheetah (Acinonyx jubatus) using single-incision laparoscopic surgery (SILS). Prospective cohort. Female cheetahs (Acinonyx jubatus) (n = 21). Cheetahs were randomly divided to receive either ovariectomy (n = 11) or salpingectomy (n = 10). The use and complications of a SILS port was evaluated in all of cheetahs. Surgery duration and insufflation volumes of carbon dioxide (CO2 ) were recorded and compared across procedures. Laparoscopic ovariectomy and salpingectomy were performed without complications using a SILS port. The poorly-developed mesosalpinx and ovarian bursa facilitated access to the uterine tube for salpingectomy in the cheetah. The median surgery duration for ovariectomy was 24 minutes (interquartile range 3) and for salpingectomy was 19.5 minutes (interquartile range 3) (P = .005). The median volume of CO2 used for ovariectomy was 11.25 L (interquartile range 3.08) and for salpingectomy was 4.90 L (interquartile range 2.52), (P = .001) CONCLUSIONS: Laparoscopic ovariectomy and salpingectomy can be performed in the cheetah using SILS without perioperative complications. Salpingectomy is faster than ovariectomy and requires less total CO2 for insufflation. © Copyright 2015 by The American College of Veterinary Surgeons.

To evaluate the role of different clinical, biochemical and sonographic factors as predictors of spontaneous ovulation after laparoscopic ovarian drilling (LOD) in women with clomiphene citrate resistant polycystic ovarian disease (CCR-PCOD). This prospective study recruited 251 infertile women with CCR-PCOD. Several clinical, biochemical and sonographic criteria were tested as possible predictors of spontaneous ovulation after LOD using multivariate analysis. Women with higher preoperative levels of LH, FSH and/or androstenedione had significantly higher rates of spontaneous ovulation within the first eight weeks after LOD, but only FSH and androstenedione were found to be independent predictors. Other factors including age, BMI, type of infertility, duration of infertility, menstrual pattern, testosterone level, ovarian volume and SHBG were insignificant predictors. Receiver-operating characteristic (ROC) curves derived from FSH, LH, androstenedione, and a logistic regression model showed that the best cut-off values were 4.1IU/l, 7.8IU/l, 1.2ng/ml, and 0.4897, respectively, with sensitivity of 91.18%, 100%, 73.53%, and 88.24% and specificity of 69.57%, 69.57%, 65.22%, and 73.91% for FSH, LH, androstenedione, and logistic regression model respectively. An extended follow up (9 months after LOD) was conducted for the anovulatory and the non-pregnant ovulatory women, who were treated individually according to their clinical situation. Of these women, 53.5% (69/129) got pregnant, resulting in a cumulative pregnancy rate of 48% (82/171). Of these pregnancies, 16/82 (19.5%) were spontaneous while 35.4% (29/82) and 45.1% (37/82) occurred after ovulation induction by CC and gonadotropins, respectively. This study supports the use of androstenedione, LH and FSH as a simple reliable tool in triaging patients with CCR-PCOD to select the ideal candidates for LOD. Copyright © 2014 Elsevier Ireland Ltd.

To study the effects of the wide excision of soft tissues adjacent to the ovary and fallopian tube on ovarian function and surgical outcomes in women undergoing laparoscopic bilateral prophylactic salpingectomy. Randomized, controlled trial. Teaching hospital. One hundred eighty-six women undergoing laparoscopic surgery for uterine myoma (n = 143) or tubal surgical sterilization (n = 43). Patients were randomly divided into two groups. In group A (n = 91), standard salpingectomy was performed. In group B (n = 95), the mesosalpinx was removed within the tubes. Prior to and 3 months after surgery, antimüllerian hormone (AMH), FSH, three-dimensional antral follicle count (AFC), vascular index (VI), flow index (FI), vascular-flow index (VFI), and OvAge were recorded for each patient. Ovarian reserve modification (Δ) before and after surgery was assessed as the primary outcome. Operative time, variation of the hemoglobin level (ΔHb), postoperative hospital stay, postoperative return to normal activity, and complication rate were assessed as secondary outcomes. No significant difference was observed between groups for ΔAMH, ΔFSH, ΔAFC, ΔVI, ΔFI, ΔVFI, and ΔOvAge. Moreover, the groups were similar for operative time, ΔHb, postoperative hospital stay, postoperative return to normal activity, and complication rate. Even when the surgical excision includes the removal of the mesosalpinx, salpingectomy does not damage the ovarian reserve. Moreover, wide salpingectomy with excision of the mesosalpinx did not alter blood loss, hospitalization stay, or return to normal activities. NCT02086370.

This systematic review and meta-analysis aimed to compare the effectiveness of unilateral vs. bilateral laparoscopic ovarian drilling (ULOD vs. BLOD) for improving fertility outcomes in infertile women with clomiphene-resistant polycystic ovary syndrome (PCOS) as well as its effect on ovarian reserve. Searches were conducted on PubMed, ScienceDirect, ClinicalTrials.gov, and CENTRAL databases from January 1984 to January 2017. Only randomized trials comparing ULOD with BLOD were included. The PRISMA Statement was followed. Main outcomes were ovulation and clinical pregnancy rates per woman randomized. Secondary outcomes were; live birth and miscarriage rates as well as postoperative serum anti-mullerian hormone (AMH) concentration and antral follicle count (AFC). Quality assessment was performed by the Cochrane Collaboration risk of bias tool. Eight eligible trials (484 women) were analyzed. No significant difference was found in rates of ovulation (OR 0.73; 95% CI 0.47-1.11), clinical pregnancy (OR 0.56; 95% CI 0.22-1.41), live birth (OR 0.77; 95% CI 0.28-2.10), or miscarriage (OR 0.90; 95% CI 0.33-2.84) when ULOD was compared with BLOD. The reduction in AMH was comparable between the two procedures (MD 0.64 ng/ml; 95% CI - 0.08 to 1.36). A significantly higher AFC at 6-month follow-up was found with dose-adjusted ULOD (MD 2.20; 95% CI 1.01-3.39). After carefully weighing up the well-known benefits of BLOD against a potential risk to ovarian reserve, clinicians could be advised to offer the fixed-dose ULOD to their infertile patients with clomiphene-resistant PCOS. This is concordant with the "primum non nocere" principal if LOD will be envisaged.

To determine the number of cases a urological surgeon must complete to achieve proficiency for various urological procedures. The MEDLINE, EMBASE and PsycINFO databases were systematically searched for studies published up to December 2011. Studies pertaining to learning curves of urological procedures were included. Two reviewers independently identified potentially relevant articles. Procedure name, statistical analysis, procedure setting, number of participants, outcomes and learning curves were analysed. Forty-four studies described the learning curve for different urological procedures. The learning curve for open radical prostatectomy ranged from 250 to 1000 cases and for laparoscopic radical prostatectomy from 200 to 750 cases. The learning curve for robot-assisted laparoscopic prostatectomy (RALP) has been reported to be 40 procedures as a minimum number. Robot-assisted radical cystectomy has a documented learning curve of 16-30 cases, depending on which outcome variable is measured. Irrespective of previous laparoscopic experience, there is a significant reduction in operating time (P = 0.008), estimated blood loss (P = 0.008) and complication rates (P = 0.042) after 100 RALPs. The available literature can act as a guide to the learning curves of trainee urologists. Although the learning curve may vary among individual surgeons, a consensus should exist for the minimum number of cases to achieve proficiency. The complexities associated with defining procedural competence are vast. The majority of learning curve trials have focused on the latest surgical techniques and there is a paucity of data pertaining to basic urological procedures. © 2013 The Authors.

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

PubMed

Yeung, Christina; Dinh, Tuan; Lee, Joseph

2014-11-01

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.

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.

To compare the effect of combined metformin and clomiphene citrate (CC) with laparoscopic ovarian diathermy (LOD) meant for ovulation induction in CC-resistant women with polycystic ovary syndrome (PCOS). Two-hundred and eighty-two anovulatory women with CC-resistant PCOS were selected in this randomized controlled trial. Patients (n = 138) received combined metformin-CC for up to six cycles or underwent LOD (n = 144) with six months follow up. The outcome measures were: ovulation rate, midcycle endometrial thickness, pregnancy and miscarriage rates. Ovulation occurred in 386/576 cycles (67%) in the combined metformin-CC group and 381/558 cycles (68.2%) in LOD group without a significant difference between the groups. Resumption of regular menstruation was similar in both groups. A significant increase in midcycle endometrial thickness was observed in the combined metformin-CC group (9.2 ± 1.2 mm vs 7.6 ± 1.1 mm) (P < 0.05). The pregnancy rate was similar in both groups (15.4% vs 17%), and there were no statistically significant differences regarding the miscarriage rate between both groups. Four twin pregnancies occurred in the metformin-CC group. No ovarian hyperstimulation occurred in either group. Combined metformin-CC and LOD are equally effective for inducing ovulation and achieving pregnancy in CC-resistant PCOS patients. © 2010 The Authors.

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.

Primary borderline parovarian tumor in pregnancy

PubMed Central

Kim, Jong-Hyun

2015-01-01

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

Elevation of serum CA 125 and D-dimer levels associated with rupture of ovarian endometrioma.

PubMed

Uharcek, P; Mlyncek, M; Ravinger, J

2007-01-01

Patients with endometriosis rarely have a serum CA 125 concentration >100 IU/mL. A raised plasma level of D-dimer indicates active fibrinolysis, either secondary to clot formation or primarily activated. This condition is seldom diagnosed in patients with endometriosis. A 53-year-old woman was referred to our institution for acute abdominal pain. Laparoscopic surgery revealed a large ovarian cyst with rupture on the left side. Preoperative laboratory tests detected high serum CA 125 and D-dimer levels. Adnexectomy was performed, resulting in a sharp decrease in serum CA 125 and D-dimer concentration. We describe the clinical course of the patient. Rupture of a large ovarian endometrioma can lead to a high serum concentration of CA 125, a condition which, in addition to the detected pelvic mass, may mimic a malignant process. The increased D-dimer plasma level indicated that a ruptured endometriotic cyst can induce coagulation reactions.

To describe the evolution of controlled ovarian hyperstimulation in women with recurrent ovarian endometriomas treated with sclerotherapy. Twenty-one patients with a laparoscopic diagnosis of stage III or IV endometriosis who had an endometrioma larger than 3 cm before ovarian hyperstimulation for in vitro fertilization were included in the study. After using a GnRH agonist analog for at least 20 days, the cysts were punctured using ultrasound guidance and subsequent ethanol sclerotherapy was performed. Then, the patients were stimulated with 100 or 200 U/day of recombinant follicle stimulating hormone, varying the dose according to the patient's age or history of a previous unilateral oophorectomy. The ovarian cysts had an average diameter of 4.7 ± 1.4 cm and did not recur after aspiration during the ovulation induction. Oocyte extraction occurred after 11 days of hyperstimulation, with 3.95 ± 3.30 oocytes obtained per cycle, on average. Embryo transfer occurred in 71.4% (15/21) of patients, and the pregnancy rate after transfer was 20% (3/15). Aspiration followed by ethanol sclerotherapy prior to in vitro fertilization can be an option for patients who desire a pregnancy and have recurrent endometriomas.

To assess recurrence and pregnancy rates in women with ovarian endometrioma treated via ablation using plasma energy. Retrospective non-comparative pilot study including 55 patients treated during 28 months, with prospective recording of data (Canadian Task Force classification II-2). Tertiary referral center. Fifty-five consecutive women with pelvic endometriosis in whom ovarian endometriomas were managed solely via ablation using plasma energy. The minimum follow-up was 1 year. Endometrioma ablation using plasma energy. Information was obtained from the database of the North-West Inter Regional Female Cohort for Patients with Endometriosis, based on self-questionnaires completed before surgery, surgical and histologic data, and systematic recording of recurrences, pregnancy, and symptoms. Recurrences were assessed using pelvic ultrasound examination. Mean (SD) follow-up was 20.6 (7.2) months (range, 12-39 months). In 75% of patients, deep infiltrating endometriosis was treated, and 40% had colorectal involvement. Preoperative infertility was recorded in 42% of patients. The rate of postoperative recurrence was 10.9% for the entire series. Of 33 women who wished to conceive, 67% became pregnant, spontaneously in 59%. Time from surgery to the first pregnancy was 7.6 (4.3) months. After discontinuation of postoperative hormone therapy, the probability of not conceiving at 12 months was 0.36 (95% confidence interval, 0.19-0.53), and at 24 months was 0.27 (95% confidence interval, 0.12-0.44). Recurrence and pregnancy rates are encouraging in that they seem comparable to the best reported results after endometrioma cystectomy. Plasma energy may have an important role in the management of ovarian endometrioma in women seeking to conceive. Patients most in need of surgical procedures that can spare ovarian parenchyma, such as those with bilateral endometriomas or a history of ovarian surgery, may particularly benefit from ablation using plasma energy.

Laparoscopic ovariectomy was performed in two Asiatic black bears ( Ursus thibetanus ). Bears were placed in a 20° Trendelenburg position on a surgical table. A three-portal technique was used. A camera port was established 10 cm caudal to the umbilicus with a 5-mm cannula. Two instrument ports were made 1 cm caudal to the umbilicus with a 5-mm cannula and 8 cm caudal to the camera port with a 12-mm cannula, respectively. The suspensory ligament, ovarian vasculature, and uterine horn tip were progressively dissected following coagulation with the Sonicision™ cordless ultrasonic dissection device. The resected ovary was exteriorized through the 12-mm instrument portal site but enlarged to a 2-cm incision length. The abdominal musculature, subcutaneous tissue, and skin of the portal sites were closed separately. Total surgical time was 113 min (Bear A) and 49 min (Bear B), and no postoperative complications were encountered. This is the first report of laparoscopic ovariectomy in the Asiatic black bear.

Pregnancy outcome in women with polycystic ovary syndrome comparing the effects of laparoscopic ovarian drilling and clomiphene citrate stimulation in women pre-treated with metformin: a retrospective study

PubMed Central

2010-01-01

Background Ovarian stimulation in women with polycystic ovary syndrome (PCOS) increases the risk for perinatal complications. Ovulation induction by laparoscopic ovarian drilling (LOD) might improve the overall pregnancy outcomes. The aim of our study was to assess the adverse events or effects on pregnancy of LOD and clomiphene citrate (CC) stimulation in patients who received metformin. Methods Setting: Academic research institution. We retrospectively analyzed the courses of 40 spontaneous pregnancies after LOD for CC-resistance, 40 pregnancies after CC stimulation, and 40 pregnancies after metformin treatment alone. Patients in the LOD and the CC groups had been pre-treated with Metformin. Primary outcome parameters were: the rate of multiple pregnancies; the rate of early pregnancy losses/miscarriages; the development of gestational diabetes, pregnancy-induced hypertension, and preeclampsia/HELLP-syndrome; premature delivery; and birth weight. Results The rate of twin pregnancies did not differ between the CC group (12.5%), the LOD group (7.5%), and the metformin only group (2.5%, p = 0.239). Seventeen women suffered an early miscarriage. There were no differences with regard to the rates of gestational diabetes, pregnancy-induced hypertension, preeclampsia, and preterm delivery. By analyzing all pregnancy complications together, the overall pregnancy complication rate was highest in the CC group (70.0%, 28/40), followed by the LOD group (45.0%, 18/40), and the metformin only group (47.5%, 19/40; p = 0.047). Conclusions CC, but not LOD, increases the complication rate in pregnant patients who received metformin. PMID:20465786

To compare the perioperative outcomes of minimally invasive secondary cytoreduction surgery (SCS) plus hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) versus open surgery plus HIPEC in a group of platinum-sensitive patients with advanced epithelial ovarian cancer (AEOC) with isolated relapse. Retrospective cohort study (Canadian Task Force classification II-2). Department of Obstetrics and Gynecology, Division of Gynecologic Oncology, Catholic University of the Sacred Heart, Rome, Italy. We selected 22 patients with a peritoneal cancer index value of 2. The laparoscopic group consisted of 11 patients who underwent laparoscopic and/or robotic complete cytoreduction plus HIPEC, whereas the laparotomic group consisted of 11 patients who underwent complete laparotomic cytoreduction plus HIPEC. The minimally invasive surgery (MIS) group were platinum-sensitive single recurrent ovarian cancer patients who underwent either laparoscopic or robotic complete secondary cytoreduction plus HIPEC, whereas the open group were women with similar clinical characteristics who underwent complete secondary cytoreduction plus HIPEC by laparotomy. The median operative time, calculated from the skin incision to the end of SCS (i.e., excluding HIPEC phase) was 125 min (range 95-150 min) in the MIS group and 295 min (range 180-420) in the open group (p = .001), with a median estimated blood loss of 50 mL (range 50-100) and 500 mL (range 50-1300), respectively (p = .025). The median length of hospital stay was 4 days (range 3-17) in the MIS group and 8.5 days (range 4-30) in the open group (p = .002). No statistically significant differences were registered in terms of intra- and postoperative complications between the 2 groups. The minimally invasive approach for SCS plus HIPEC is safe and efficient in terms of toxicity and postoperative outcomes for single isolated relapse. HIPEC should not be considered a major contraindication to a minimally invasive approach. Copyright © 2015 AAGL. Published by Elsevier Inc. All rights reserved.

Diffusion of robotics into clinical practice in the United States: process, patient safety, learning curves, and the public health.

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 study uniquely described the clinical value of transabdominal ultrasonography for monitoring features characterizing the estrous cycle in female cheetahs (Acinonyx jubatus). The reproductive tracts of 21 female, nulliparous, and relatively aged (median: 11 and interquartile range: 9.25-14 years) captive cheetahs resident on two sites in Namibia were assessed by transabdominal ultrasound. Subsequently, the ovarian findings on ultrasound were compared with direct visualization while performing laparoscopic sterilization. A combination of these observations supported by concurrent sampling for vaginal cytology and serum progesterone concentrations defined the estrous status of individual animals. At one site, six cheetahs had been implanted with the GnRH agonist, deslorelin as a contraceptive at least once within the preceding 11 years. On ultrasound, 31 uterine horns and 35 ovaries with discernible structures on 28 (86%) were visualized in the 21 cheetahs. The uterine body was difficult to visualize because of its intrapelvic location. Eleven of 19 uteri (58%) visualized showed endometrial edema suggestive of estrogenization. The uteri of four cheetahs (19%) showed evidence of mild cystic endometrial hyperplasia. Paraovarian cysts were seen on ultrasound (n = 21) and laparoscopy (n = 26) in 16 (76.2%) and 18 (85.7%) cheetahs, respectively. Ovarian volumes obtained from ultrasonographically determined dimensions predicted cyclic activity. Laparoscopy showed that 19 ovaries had discernible follicular structures. In the study population, 10 (47.6%) cheetahs were in proestrus or estrus; none in the luteal phase; and 11 (52.4%) in anestrus. Transabdominal ultrasound, in combination with serum progesterone concentrations and vaginal cytology, was used with acceptable accuracy to assess cyclic ovarian activity in captive cheetahs. A considerable proportion of this aged population showed ovarian activity and the prevalence of paraovarian cysts was notable. A history of prior deslorelin treatment was not associated with either reproductive activity or uterine pathology. Copyright © 2015 Elsevier Inc. All rights reserved.

Radical cystectomy is a surgical treatment for recurrent non-muscle-invasive and muscle-invasive bladder cancer; however, many patients may not receive this treatment. A total of 27,578 patients diagnosed with clinical stage I-IV bladder cancer from 1 January 2007 to 31 December 2013 were identified from the Surveillance, Epidemiology, and End Results (SEER) registry database. We used multivariable regression analyses to identify factors predicting the use of radical cystectomy and pelvic lymph node dissection. Cox proportional hazards models were used to analyze survival outcomes. A total of 1,693 (6.1%) patients with bladder cancer underwent radical cystectomy. Most patients (92.4%) who underwent radical cystectomy also underwent pelvic lymph node dissection. When compared with white patients, non-Hispanic blacks were less likely to undergo a radical cystectomy [odds ratio (OR) 0.79, 95% confidence interval (CI) 0.64-0.96, p = 0.019]. Moreover, recent year of surgery 2013 versus 2007 (OR 2.32, 95% CI 1.90-2.83, p < 0.001), greater percentage of college education ≥36.3 versus <21.3% (OR 1.23, 95% CI 1.04-1.44, p = 0.013), Midwest versus West (OR 1.64, 95% CI 1.39-1.94, p < 0.001), and more advanced clinical stage III versus I (OR 29.1, 95% CI 23.9-35.3, p < 0.001) were associated with increased use of radical cystectomy. Overall survival was improved for patients who underwent radical cystectomy compared with those who did not undergo a radical cystectomy (hazard ratio 0.88, 95% CI 0.80-0.97, p = 0.008). There is significant underutilization of radical cystectomy in patients across all age groups diagnosed with bladder cancer, especially among older, non-Hispanic black patients.

In this study, we compared perioperative and oncologic outcomes of patients treated with either open or robot-assisted radical cystectomy and intracorporeal neobladder at a tertiary care center. The institutional prospective bladder cancer database was queried for "cystectomy with curative intent" and "neobladder". All patients underwent robot-assisted radical cystectomy and intracorporeal neobladder or open radical cystectomy and orthotopic neobladder for high-grade non-muscle invasive bladder cancer or muscle invasive bladder cancer with a follow-up length ≥2 years were included. A 1:1 propensity score matching analysis was used. Kaplan-Meier method was performed to compare oncologic outcomes of selected cohorts. Survival rates were computed at 1,2,3 and 4 years after surgery and the log rank test was applied to assess statistical significance between the matched groups. Overall, 363 patients (299 open and 64 robotic) were included. Open radical cystectomy patients were more frequently male (p = 0.08), with higher pT stages (p = 0.003), lower incidence of urothelial histologies (p = 0.05) and lesser adoption of neoadjuvant chemotherapy (<0.001). After applying the propensity score matching, 64 robot-assisted radical cystectomy patients were matched with 46 open radical cystectomy cases (all p ≥ 0.22). Open cohort showed a higher rate of perioperative overall complications (91.3% vs 42.2%, p 0.001). At Kaplan-Meier analysis robotic and open cohorts displayed comparable disease-free survival (log-rank p = 0.746), cancer-specific survival (p = 0.753) and overall-survival rates (p = 0.909). Robot-assisted radical cystectomy and intracorporeal neobladder provides comparable oncologic outcomes of open radical cystectomy and orthotopic neobladder at intermediate term survival analysis.

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.

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 is to report the current status of ovarian tissue cryopreservation among alternatives for fertility preservation in the Nordic countries. A questionnaire was sent to 14 Nordic academic reproductive centers with established fertility preservation programs. It covered fertility preservation cases performed up to December 2014, standard procedures for ovarian tissue cryopreservation and oocyte cryopreservation and reproductive outcomes following ovarian tissue transplantation. Among the Nordic countries, Denmark and Norway practice ovarian tissue cryopreservation as a clinical treatment (822 and 164 cases, respectively) and their programs are centralized. In Sweden (457 cases), ovarian tissue cryopreservation is practiced at five of six centers and in Finland at all five centers (145 cases). Nearly all considered ovarian tissue cryopreservation to be experimental. In Iceland, embryo cryopreservation is the only option for fertility preservation. Most centers use slow-freezing methods for ovarian tissue cryopreservation. Most patients selected for ovarian tissue cryopreservation were newly diagnosed with cancer and the tissue was predominantly retrieved laparoscopically by unilateral oophorectomy. Only minor complications were reported. In total, 46 women have undergone ovarian tissue transplantation aiming at recovering fertility, 17 healthy children have been born and several additional pregnancies are currently ongoing. Whenever patients' clinical condition is permissive, oocyte cryopreservation after hormonal stimulation is preferred for fertility preservation. Between 2012 and 2014, a smaller proportion of females have undergone fertility preservation in the Nordic centers, in comparison to males (1:3). Overall, ovarian tissue cryopreservation was reported to be safe. Slow freezing methods are still preferred. Promising results of recovery of fertility have been reported in Nordic countries that have initiated ovarian tissue transplantation procedures. © 2016 The Authors.

To present the feasibility of single-port laparoscopic surgery at patients with deep infiltrating endometriosis. Step by step explanation of the surgery using videos (Canadian Task Force classification III-c). Single-port laparoscopic surgery is an emerging technique and an option for improving the benefits of laparoscopic surgery. The goals of single-port laparoscopic surgery is to further enhance the cosmetic benefits of minimally invasive surgery and minimize the potential risk and morbidity associated with multiport surgery [1,2]. This procedure is not without challenges, however, such as instrument crowding and clashing, ergonomic difficulties, loss of instrument triangulation, and the need for advanced laparoscopic skills [1,2]. Despite these challenges, technical advances in optics and instrumentation have led to the widespread use of single-port laparoscopic surgery to treat such gynecologic disorders as endometriosis, uterine myomas, and cancers [2,3]. A 42-year-old woman was admitted to our clinic with a complaint of chronic pelvic pain dysmenorrhea and deep dyspareunia. Her medical history revealed a cesarean section delivery and a diagnosis of endometriosis. Despite treatment of her endometriosis with dienogest, there has been no decline at her complaints. Ultrasound examination performed at admission revealed a 6 × 6 cm right adnexal mass compatible with endometrioma, with a normal left ovary and uterus. Rectovaginal examination detected no endometriotic nodules. Although all treatment options were explained and discussed and laparoscopic excision of right ovarian endometrioma was recommended, the patient strongly desired removal of the uterus and the ovaries to avoid recurrence of endometriosis and related complaints. Thus, laparoscopic hysterectomy and bilateral salpingo-oophorectomy were planned. Under general anesthesia and endotracheal intubation, the patient was placed in low lithotomy position with the arms tucked. An orogastric tube and a Foley catheter were placed. Abdominal access was performed following an open Hasson technique with a 2.0- to 2.5-cm vertical umbilical incision and a 4-channel (with two 10-mm and two 5-mm channels) access port was placed into the peritoneal cavity. On pelvic examination, a 6 × 6-cm right ovarian endometrioma adherent to the pelvic sidewall was detected, along with severe adhesions on the left side between the left adnex and the pelvic sidewall. The uterus was normal. The adhesion on the left side was released using a Harmonic scalpel (Ethicon Endosurgery, Cinncinnati, OH). The pelvic sidewall peritoneum was opened, and the ureters were identified and isolated at the pelvic brim and followed toward the true pelvis. The internal iliac artery, uterine and obliterated umbilical artery, and infundibulopelvic ligament were dissected and identified. The paravesical, pararectal, and rectouterine spaces were opened. Deep infiltrating endometriosis implants on the right side located in the uterosacral ligment and pararectal space were dissected and excised. After restoration of pelvic anatomy, hysterectomy and bilateral salpingo-oophorectomy were performed. The vaginal cuff was closed with intracorporeal knots. The patient was discharged on postoperative day 1, and reported no problems at follow-up. Single-port laparoscopic hysterectomy appears to be a safe and feasible option in patients with deep infiltrating endometriosis, especially when performed by well-experienced surgeons.

Surgical management in epithelial ovarian cancer (EOC) has a significant impact in overall survival (OS) and progression free survival (PFS). Brazilian Society of Surgical Oncology (BSSO) supported a taskforce with experts for consensus: experienced and specialized trained surgeons, in cancer centers, provide the best EOC surgery. Laparoscopic and/or radiological staging prognosticate the possibility of complete cytoreduction (CC0) and help to reduce unnecessary laparotomies. Surgical techniques were reviewed. Multidisciplinary input is essential for treatment planning. Quality assurance criteria are proposed and need national consensus. Genetic testing is mandatory. This consensus states the final recommendations from BSSO for management of EOC. This article is protected by copyright. All rights reserved. This article is protected by copyright.

Anovulation and ovulation induction

PubMed Central

Katsikis, I; Kita, M; Karkanaki, A; Prapas, N; Panidis, D

2006-01-01

Conventional treatment of normogonadotropic anovulatory infertility is ovulation induction using the antiestrogen clomiphene citrate, followed by follicle-stimulating hormone. Multiple follicle development, associated with ovarian hyperstimulation, and multiple pregnancy remain the major complications. Cumulative singleton and multiple pregnancy rate data after different induction treatments are needed. Newer ovulation induction interventions, such as insulin-sensitizing drugs, aromatase inhibitors and laparoscopic ovarian electrocoagulation, should be compared with conventional treatments. Ovulation induction efficiency might improve if patient subgroups with altered chances for success or complications with new or conventional techniques could be identified, using multivariate prediction models based on initial screening characteristics. This would make ovulation induction more cost-effective, safe and convenient, enabling doctors to advise patients on the most effective and patient-tailored treatment strategy. PMID:20351807

Primary adnexial hydatid cyst mimicking ovarian tumor

Görgen, Hüsnü; Api, Murat; Çetin, Ahmet

2009-01-01

We report here the rare case of a 28-year-old woman with a large hydatid cyst in her left lower pelvis with an unusual sonographic presentation mimicking a multicystic ovarian tumor. Laparoscopic evaluation revealed normal uterus and ovaries with a swelling in the left retropritoneal area. We decided to reach this tumour by the vaginal route and multiple scolex, daughter cysts were removed via a left lateral vaginal wall incision. The pericystic cavity was thoroughly washed. The patient was discharged on the first postoperative day. Mebendazole (100 mg twice daily) was administered for 4 months. This parasite should be kept in mind and considered when making the differential diagnosis of pelvic cystic masses, particularly if the patient is from an endemic area. PMID:24591878

2010-06-01

The purpose of this study was to compare the effectiveness of laparoscopic ovarian diathermy (LOD) vs clomiphene citrate (CC) plus metformin in infertile patients with CC-resistant polycystic ovary syndrome (PCOS). Fifty primary infertile patients with CC-resistant PCOS were assigned randomly to receive LOD followed by a 6-month observation (group A) or 6-cycle course of CC plus metformin (group B). Reproductive and safety outcomes were analyzed. No significant difference between 2 groups in pregnancy (15/92 women [16.3%] vs 14/107 women [13.1%]; P = .521) and live-birth (13/92 women [14.1%] vs 12/107 women [11.2%]; P = .536) rates per cycle was observed. With the use of a Cox regression analysis, patients under medical treatment, compared with patients who received surgical treatment, had a relative risk of pregnancy of 1.2 (95% confidence interval, 0.61-2.44; P = .582) and a relative risk of live-birth of 1.4 (95% confidence interval, 0.63-2.96; P = .425). LOD and CC plus metformin seem to be 2 effective approaches to treat infertility in patients with CC-resistant PCOS. Copyright 2010 Mosby, Inc. All rights reserved.

Robotic-assisted fertility-sparing surgery for early ovarian cancer.

PubMed

Finger, Tamara Natasha; Nezhat, Farr Reza

2014-01-01

To show the feasibility and safety of robotic-assisted laparoscopic fertility-sparing surgery for earlystage ovarian cancer in women of reproductive age. The first patient was a 29-year-old para 0 woman with well-differentiated endometrioid adenocarcinoma of the ovary and complex endometrial hyperplasia with marked atypia. The second patient was a 31-year-old para 0 woman with an immature grade 1 teratoma. Both patients underwent robotic-assisted laparoscopic surgical staging. In the first patient, there were no intra- or postoperative complications. Operative time was 5 hours 43 minutes and estimated blood loss was 100 mL. She was discharged home on postoperative day 1. She received 3 cycles of carboplatin and paclitaxel, as well as medroxyprogesterone acetate for the duration of chemotherapy. She conceived twice spontaneously since surgery and had two successful deliveries. She currently has no evidence of disease. In the second patient, there were no intra- or postoperative complications. Operative time was 2 hours 52 minutes and estimated blood loss was 200 mL. She was discharged home on postoperative day 1. She declined adjuvant chemotherapy with bleomycin, etoposide, and cisplatin. She conceived spontaneously 4 months later and had a normal vaginal delivery. She currently has no evidence of disease. Because fertility-sparing surgery is now accepted as a viable option in young women with earlystage ovarian cancer, less invasive techniques are being used. With the advent of robotic-assisted surgery and its advantages over conventional laparoscopy, we show that it is a safe and feasible approach in select patients. This is the first reported series on robotic fertility-sparing surgery, but more research is needed.

Which reproductive endocrine changes are attributed exclusively to laparoscopic ovarian drilling in polycystic ovarian syndrome (PCOS)? Laser evaporation-specific endocrine effects were the prevention of an immediate increase in inhibin B and a sustained decrease in testosterone, androstenedione and anti-Müllarian hormone (AMH). All ovarian drilling procedures result in reproductive endocrine changes. It is not known which of these changes are the result of ovarian drilling and which are related to the surgery per se. This prospective controlled study was performed at an outpatient academic fertility clinic. Between 2007 and 2010, a total of 21 oligo- or amenorrheic PCOS patients were included. Included were oligo- or amenorrheic PCOS patients with all three of the Rotterdam criteria and luteinizing hormone (LH) >6.5 U/l. All PCOS patients had an indication for diagnostic surgery due to subfertility. There were 12 PCOS patients who chose to undergo ovarian laser evaporation (CO2 laser, 25 W, 20 times/ovary) and 9 PCOS who chose a diagnostic laparoscopy only (controls). Reproductive endocrinology was measured before, and until 5 days after, surgery, and four gonadotrophin-releasing hormone (GnRH) 'double pulse' tests were included. The main outcome measures were changes in reproductive endocrinology and pituitary sensitivity/priming to GnRH after laser evaporation compared with diagnostic laparoscopy only. In the first hours after surgery, both groups showed an increase in LH, follicle stimulating hormone, estrogen and a decrease in testosterone, androstenedione, AMH and insulin growth factor-1 (P < 0.05). Inhibin B increased in the laparoscopy only group (P < 0.05). In the first days after surgery, testosterone, androstenedione and AMH remained at lower than baseline levels exclusively in the laser group (P < 0.05). Pituitary sensitivity/priming to GnRH was not altered after either laser evaporation or laparoscopy only. The limitations of this study are the short follow-up period and the relatively small groups. The strength of this study is the integrally measured endocrine profiles in combination with an optimal control group of PCOS patients undergoing diagnostic laparoscopy only. Interestingly, most of the immediate endocrine changes after laser evaporation could be related to the surgical context and not to the ovarian drilling procedure itself.

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.

Radical cystectomy at Roswell Park Memorial Institute. Preoperative and post operative observations.

Between January 1979 and March 1983, 63 consecutive patients underwent cystectomy and urinary diversion for primary carcinoma of the bladder at Roswell Park Memorial Institute (RPMI). Fifty-five patients had transitional cell carcinoma, 6 squamous cell carcinoma and 2 adenocarcinoma of the bladder. Twelve patients with bladder cancer were found to have adenocarcinoma of the prostate on the pathological specimen. Preoperative radiation was given to 41 patients. Thirty-six patients received 4000 rads preoperatively followed by radical cystectomy, 5 patients received 2000 rads. Thirteen patients received 6000 rads as curative treatment and underwent salvage cystectomy and colon conduit because of failure. There was no operative mortality. Severe complications in the early postoperative period occurred in 19 instances, some patients having more than one complication. Late complications necessitating surgical correction occurred in 5 patients. Although radical cystectomy is effective in controlling the local disease, most patients still died of metastatic transitional cell carcinoma.

Laparoscopic ovarian drilling versus GnRH antagonist combined with cabergoline as a prophylaxis against the re-development of ovarian hyperstimulation syndrome.

The aim of this work was to investigate the value of laparoscopic ovarian drilling (LOD) compared with GnRH antagonist flexible protocol combined with cabergoline (Cb), as a prophylaxis against the re-development of ovarian hyperstimulation syndrome (OHSS) in women with clomiphene citrate-resistant polycystic ovary disease (CCR-PCOD) who had severe OHSS before in a previous ICSI cycle. It is a prospective controlled study, where 250 CCR-PCOD women (n = 250) with a history of severe OHSS before, had been recruited for the study. LOD had been performed for 120 (n = 120) of the recruited women before ovarian induction, and considered as group A. GnRH antagonist (Cetrotide 0.25 mg) was added when a leading follicle reaches 14-16 mm combined with oral Cb in a dose 0.5 mg a day before hCG, and for 8 d for another 130 (n = 130) women, and considered as group B. Pregnancy was diagnosed with BhCG level ≥25 IU/L, ± 14 d after embryo transfer, followed with transvaginal ultrasound scanning (TVS) 2 weeks later to confirm intra-uterine pregnancy (IUP). Women were followed up weekly for 3 months for the possible development of any signs and symptoms of OHSS. None of the participants in group A developed severe OHSS, and only six women (5%) developed mild to moderate OHSS. The incidence of severe OHSS was significantly higher (n = 3, 15%) in group B compared with group A (p < .001). Another (n = 17, 13.3%) women in group B developed mild to moderate OHSS. The probability of developing severe OHSS was also significantly higher in group B as well (p = .031). Pregnancy rate (PR) was significantly higher in group A more than group B (67% versus 39%, respectively), and all were single intrauterine pregnancies (IUP) and all developed after fresh embryo transfer (ET), compared with frozen embryo transfer (FET) which was performed in 42 cases in group B after postponing ET due to significantly severe OHSS developed. LOD could be considered a good prophylactic measure against OHSS, in addition to improving the total outcome of IVF cycles in women with CCR-PCOS.

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.

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.

Different gonadotropin-releasing-hormone agonist (GnRH-a) formulations with different potency and associated side effects, therefore, different compliance and persistence of therapy. This study was to evaluate the difference of hormonal profile and side effects due to hypoestrogenic status after treatment of leuprorelin and triptorelin in Chinese women with ovarian endometrioma after conservative surgical treatment. A total of 302 women underwent laparoscopic excision of ovarian endometriomas with rASRM III and IV were enrolled in the study.Subjects were randomized into two groups with use of a random table. Twenty two patients dropped out during the study. Thus 142 patients had three doses of i.m. leuprorelin (group A) and 138 patients had three doses of i.m. triptorelin(group B) at 4 weeks intervals after surgical treatment. Menopausal symptoms were evalutaed using a questionnaire and serum sex hormonal levels were also measured during the follow-up. At week 4 after the treatment, most of the patients in leuprorelin group have no obvious side effects. After 9 weeks, bone pain, hot flashes and sweating, and irregular bleeding were the main side effects and showed no difference between the groups. Anxiety, depression, vaginal dryness, headache, and acne rates were all significantly higher in triptorelin group than in leuprorelin group. A significant difference in FSH (p=0.003), LH (p=0.026) and E2 (p=0.002) levels between the groups were observed after 21 days of the GnRHa treatment. The FSH (p=0.021) and E2 (p=0.033) levels remained higher in the leuprorelin group than the triptorelin group after six weeks of treatment, but the difference of LH(p=0.917) level was no longer discernible. Leuprorelin in down-regulating the pituitary-ovarian function was more moderate, and the hormonal levels decrease progressively and gradually, therefore, with lower rate of menopausal symptoms. Leuprorelin acetate maybe better tolerated than triptorelin. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Gonadotropin Therapy versus Laparoscopic Ovarian Drilling in Clomiphene Citrate-Resistant Polycystic Ovary Syndrome Patients: A Retrospective Cost-Effectiveness Analysis.

Gonadotropin therapy and laparoscopic ovarian drilling (LOD) are treatment options for ovulation induction (OI) in clomiphene citrate (CC)-resistant polycystic ovary syndrome (PCOS) patients. The current evidence of the cost-effectiveness of both treatments is scarce, conflicting and performed from different health-economic perspectives. A retrospective health-economic evaluation was performed from a societal perspective in which human menopausal gonadotropin (hMG) therapy (n = 43) was compared with LOD (n = 35), followed by OI with CC and/or hMG if spontaneous ovulation did not occur within 2 months. Data were collected until the patients were pregnant, with a time limit of 6 months after the onset of treatment. Outcomes were expressed as ongoing pregnancy rate and number of live-born children. The ongoing pregnancy rate was 21/35 (60%) after LOD and 30/43 (69.8%) after hMG treatment (relative risk 0.85, 95% CI 0.61-1.19). The societal cost per patient, up to an ongoing pregnancy, was significantly higher after LOD versus hMG treatment (adjusted mean difference EUR 1,073, 95% CI 180-1,967). This economic evaluation based on real-life data shows that the societal cost up to an ongoing pregnancy is less after hMG treatment when compared with LOD surgery in CC-resistant PCOS patients. © 2015 S.

To analyze the relationship between visuospatial ability and simulated laparoscopy performed by consultants in obstetrics and gynecology (OBGYN). This was a prospective cohort study carried out at two community hospitals in Sweden. Thirteen consultants in obstetrics and gynecology were included. They had previously independently performed 10-100 advanced laparoscopies. Participants were tested for visuospatial ability by the Mental Rotations Test version A (MRT-A). After a familiarization session and standardized instruction, all participants subsequently conducted three consecutive virtual tubal occlusions followed by three virtual salpingectomies. Performance in the simulator was measured by Total Time, Score and Ovarian Diathermy Damage. Linear regression was used to analyze the relationship between visuospatial ability and simulated laparoscopic performance. The learning curves in the simulator were assessed in order to interpret the relationship with the visuospatial ability. Visuospatial ability correlated with Total Time (r=-0.62; p=0.03) and Score (r=0.57; p=0.05) in the medium level of the virtual tubal occlusion. In the technically more advanced virtual salpingectomy the visuospatial ability correlated with Total Time (r=-0.64; p=0.02), Ovarian Diathermy Damage (r=-0.65; p=0.02) and with overall Score (r=0.64; p=0.02). Visuospatial ability appears to be related to the performance of gynecological laparoscopic procedures in a simulator. Testing visuospatial ability might be helpful when designing individual training programs. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Lymphatic complications are a common occurrence after staging surgery for early-stage ovarian cancer (eEOC). We investigated whether the introduction of minimally invasive surgery influences the risk of developing lymphoceles and lymphorrhea in patients undergoing staging for eEOC. For this purpose, data of consecutive patients affected by eEOC undergoing staging surgery between January 1980 and January 2016 were retrospectively reviewed, and a systematic review and meta-analysis was performed. This systematic review was registered in the International Prospective Register of Systematic Review. Among 341 patients included in the present study, 47 severe postoperative complications occurred (13.7%), including 40 lymphatic complications: 31 symptomatic lymphoceles (9%) and 9 cases of lymphorrhea (2.6%), respectively. Laparoscopic staging correlated with a lower risk of developing any severe lymphatic complications in comparison with open surgery (p = .02). In particular, the laparoscopic approach and para-aortic node involvement were associated with a trend toward lower lymphoceles (odds ratio, .13; 95% confidence interval, .07-2.20; p = .05) and a trend toward higher risk of lymphorrhea developing (odds ratio, 4.02; 95% confidence interval, .93-17.3; p = .06), respectively. In conclusion, the implementation of a minimally invasive approach might result in a slight reduction of lymphatic complications after eEOC staging. Copyright © 2017 AAGL. Published by Elsevier Inc.

Aim of the study was to asses and compare serum anti-Mullerian harmone (AMH) levels after laparoscopic ovarian drilling (LOD) and transvaginal hydrolaparoscopy (THL) ovarian drilling in clomifene citrate (CC)-resistant polycystic ovary syndrome (PCOS) patients; secondary outcome was to evaluate postoperative pain to estimate the acceptability of procedures. A total of 246 patients with CC-resistant PCOS were randomized into two groups: 123 underwent LOD and 123 underwent THL ovarian drilling. AMH serum levels were evaluated before and after the procedure; moreover, women were asked to rate pain on a visual analog scale (VAS) from 0 (no pain, perfectly acceptable) to 10 (unbearable pain, completely unacceptable). In both groups, postoperative serum AMH levels were significantly reduced compared to preoperative levels (6.06 ± 1.18 and 5.84 ± 1.16 versus 5.00 ± 1.29 and 4.83 ± 1.10; p < 0.0001). Comparing postoperative serum AMH levels, no statistically significant difference was observed between the two surgical technique. After the procedure, mean pain VAS score was significantly higher for women who underwent LOD ovarian drilling in comparison to THL (3.26 ± 1.1 versus 1.11 ± 0.5; p < 0.0001). In conclusion, THL ovarian drilling is comparable to the LOD in terms of reduction in AMH, but it is preferred by patients in terms of acceptability. These results could support to use of THL ovarian drilling in the treatment of patients with CC- resistant PCOS.

The objective of this study is to compare ovarian function and surgical outcomes between patients affected by benign uterine pathologies submitted to total laparoscopic hysterectomy (TLH) plus salpingectomy and women in which standard TLH with adnexal preservation was performed. We retrospectively compared data of 79 patients who underwent TLH plus bilateral salpingectomy (group A), with those of 79 women treated by standard TLH without adnexectomy (sTLH) (group B). Ovarian reserve modification, expressed as the difference between 3 months post-operative and pre-operative values of Anti-Müllerian Hormone (AMH), Follicle Stimulating Hormone (FSH), Antral Follicle Count (AFC), mean ovarian diameters and Peak Systolic Velocity (PSV), was recorded for each patient. For each surgical procedure, operative time, variation of hemoglobin level (ΔHb), postoperative hospital stay, postoperative return to normal activity, and complication rate were recorded as secondary outcomes. According to our post-hoc analysis, this equivalence study resulted to have a statistical power of 96.8%. Significant difference was not observed between groups with respect to ΔAMH (p=0.35), ΔFSH (p=0.15), ΔAFC (p=0.09), Δ mean ovarian diameters (p=0.57) and ΔPSV (p=0.61). In addition, secondary outcomes such as operative time (p=0.79), ΔHb (p=0.41), postoperative hospital stay (p=0.16), postoperative return to normal activity (p=0.11) and complication rate also did not show any significant difference. The addition of bilateral salpingectomy to TLH for prevention of ovarian cancer in women who do not carry a BRCA1/2 mutations do not show negative effects on the ovarian function. In addition, no perioperative complications are related to the salpingectomy step in TLH. Copyright © 2013 Elsevier Inc. All rights reserved.

Laparoscopic ovariohysterectomy using single-portal access was performed in nine selected owned dogs admitted for elective ovariohysterectomy and the surgical technique and outcomes were detailed. A multiport device (SILS Port, Covidien, USA) was placed at the umbilical area through a single 3 cm incision. Three cannulae were introduced in the multiport device through the access channels and laparoscopic ovariohysterectomy was performed using a 5-mm sealing device, a 5-mm articulating grasper and a 5-mm 30° laparoscope. The mean total operative time was 52.66±15.20 minutes and the mean skin incision during surgery was 3.09±0.20 cm. Of the nine cases examined, in the one with an ovarian tumour, the technique was converted to multiport laparoscopy introducing an additional 5-mm trocar. No surgical complications were encountered and intraoperative blood loss was minimum in all animals. Clashing of the instruments and reduced triangulation were the main limitations of this technique. The combination of articulated and straight instruments facilitated triangulation towards the surgical field and dissection capability. One month after surgery a complete wound healing was observed in all animals. The present data showed that ovariohysterectomy performed with a single-port access is technically feasible in dogs. The unique abdominal incision minimises the abdominal trauma with good cosmetic results. PMID:26568831

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.

Clostridium Difficile is the most common cause of nosocomial infectious diarrhea. This study evaluates the prevalence and predictors of Clostridium Difficile infections in patients undergoing radical cystectomy with or without neoadjuvant chemotherapy. Retrospective chart review was performed of all patients undergoing cystectomy and urinary diversion at a single institution from 2011-2017. Infection was documented in all cases with testing for Clostridium Difficile polymerase chain reaction toxin B. Patient and disease related factors were compared for those who received neoadjuvant chemotherapy vs. those who did not in order to identify potential risk factors associated with C. Difficile infections. Chi squared test and logistic regression analysis were used to determine statistical significance. Of 350 patients who underwent cystectomy, 41 (11.7%) developed Clostridium Difficile in the 30 day post-operative period. The prevalence of C. Difficile infection was higher amongst the patients undergoing cystectomy compared to the non-cystectomy admissions at our hospital (11.7 vs. 2.9%). Incidence was not significantly different among those who underwent cystectomy for bladder cancer versus those who underwent the procedure for other reasons. Median time to diagnosis was 6 days (range 3-28 days). The prevalence of C. Diff infections was not significantly different among those who received neoadjuvant chemotherapy vs. those who did not (11% vs. 10.4% p  = 0.72). A significant association between C. Difficile infection was not seen with proton pump inhibitor use ( p  = 0.48), patient BMI ( p  = 0.67), chemotherapeutic regimen ( p  = 0.94), individual surgeon ( p  = 0.54), type of urinary diversion (0.41), or peri-operative antibiotic redosing ( p  = 0.26). Clostridium Difficile infection has a higher prevalence in patients undergoing cystectomy. No significant association between prevalence and exposure to neoadjuvant chemotherapy was seen.

Steen-Banasik, Elzbieta M. van der, E-mail: E.vanderSteen-Banasik@radiotherapiegroep.nl; Smits, Geert A.H.J.; Oosterveld, Bernard J.

Purpose: To report experience and early results of laparoscopic implantation for interstitial brachytherapy (BT) of solitary bladder tumors and the feasibility of a high-dose-rate (HDR) schedule. Methods and Materials: From December 2009 to April 2015, 57 patients with a T2 solitary bladder tumor were treated in Arnhem with transurethral bladder resection followed by external beam irradiation, applied to the bladder and regional iliac lymph nodes, 40 Gy in 20 fractions, 5 fractions per week, and within 1 week interstitial HDR BT, in selected cases combined with partial cystectomy and lymph node dissection. The BT catheters were placed via a transabdominal approach withmore » robotic assistance from a Da Vinci robot after a successful initial experience with a nonrobotic laparoscopic approach. The fraction schedule for HDR was 10 fractions of 2.5 Gy, 3 fractions per day. This was calculated to be equivalent to a reference low-dose-rate schedule of 30 Gy in 60 hours. Data for oncologic outcomes and toxicity (Common Toxicity Criteria version 4) were prospectively collected. Results: These modifications resulted in an average postoperative hospitalization of 6 days, minimal blood loss, and no wound healing problems. Two patients had severe acute toxicity: 1 pulmonary embolism grade 4 and 1 cardiac death. Late toxicity was mild (n=2 urogenital grade 3 toxicity). The median follow-up was 2 years. Using cumulative incidence competing risk analysis, the 2-year overall, disease-free, and disease-specific survival and local control rates were 59%, 71%, 87%, and 82%, respectively. Conclusions: The benefits of minimally invasive surgery for implantation of BT catheters and the feasibility of HDR BT in bladder cancer are documented. The patient outcome and adverse events are comparable to the best results published for a bladder-sparing approach.« less

Bilateral salpingo-oophorectomy (BSO) in carriers of BRCA1 and BRCA2 mutations is widely recommended as part of a risk-reduction strategy for ovarian or breast cancer due to an underlying genetic predisposition. BSO is also performed as a therapeutic intervention for patients with hormone-positive premenopausal breast cancer. BSO may be performed via a minimally invasive approach with the use of three to four 5 mm and/or 12 mm ports inserted through a skin incision. To further reduce the morbidity associated with the placement of multiple port sites and to improve cosmetic outcomes, single-port laparoscopy has been developed with a single access point from the umbilicus. The purpose of this study was to evaluate the surgical outcomes associated with reducing the risks of salpingo-oophorectomy performed in a single port, while comparing multiport laparoscopy in women with a high risk for ovarian cancer. Single-port laparoscopy–BSO is feasible and safe, with favorable surgical and cosmetic outcomes when compared to conventional laparoscopy. PMID:26170692

Urinary endometriosis accounts for 1% of all endometriosis where the bladder is the most affected organ. Although the laparoscopic removal of bladder endometriosis has been demonstrated to be effective in terms of symptom relief with a low recurrence rate, there is no standardized technique. Partial cystectomy allows the complete removal of the disease and is associated with low intra- and postoperative complications. Here we describe a stepwise approach to a rare case of a large endometriosis nodule affecting the trigone of the urinary bladder. Step-by-step video explanation of a large endometriotic nodule excision (Canadian Task Force classification III). IRCAD AMITS - Barretos | Hospital Pio XVI. The video was approved by the local institutional review board. A 31-year-old woman. Laparoscopic approach for bladder endometriosis. We present a case of a 31-year-old woman who complained of dysuria and hematuria with a bladder nodule of 3 cm affecting the bladder trigone. Laparoscopic complete excision of the nodule was performed. Laparoscopy began with full inspection of the pelvic and abdominal cavity. Vaginal examination under laparoscopic view helped to determinate the dimensions of the bladder nodule. Strategy consisted of bilateral dissection of the paravesical fossae and the identification of both uterine arteries and ureters. The bladder was slowly dissected from the uterine isthmus and was intentionally opened, thus helping the surgeons to identify the lateral and lower limits of the nodule and its proximity to both ureters. Bilateral double J stents were previously placed to guide the excision and further suture. Once the nodule was removed, the remaining wall consisted of the lower aspect of the trigone, both medial lower parts of the ureter, and the apex of the bladder. Suturing was performed in 2 steps. A simple monofilament interrupted suture was applied vertically at the lower wall between both ureters. The same technique was applied horizontally on the bladder dome. Pressure test demonstrated adequate correction. The patient was discharged 2 days later with a bladder catheter and double J stent. After 15 days, both indwelling catheter and ureteric stent were removed, and patient was submitted to a cystogram where no leakage was found. If a leakage had been found on the cystogram, the bladder should be allowed an additional week of continuous drainage. Early follow-up demonstrated a lower bladder capacity that was resolved within 6 months. After a 1-year follow-up the patient had no symptoms and demonstrated no recurrence. She is now 20 weeks pregnant with no need of assisted reproductive methods. The technique showed in the video demonstrates the feasibility of a laparoscopic approach for bladder endometriosis. Furthermore, the laparoscopic approach allowed the removal of the large nodule, reducing the risk of small bladder symptoms. Copyright © 2018. Published by Elsevier Inc.

Metastasis to gastrointestinal tract from breast cancer is an uncommon situation. We report a case of a 52-year-old woman who had a mastectomy for solid-tubular carcinoma of the breast 16 years ago and bilateral salpingo-oophorectomy for metastatic ovarian tumours 5 years ago, was incidentally found to have colonic metastatic tumour detected by positron emission tomography/CT (PET/CT) during follow-up. After identifying a definite location of the tumour in the ascending colon under laparoscopic investigation, laparoscopy-assisted partial colectomy was successfully performed. Histopathology of the resected specimen showed it to be metastasis from solid-tubular carcinoma of the breast. We should be aware that breast cancer can metastasise to the gastrointestinal tract even after the long interval from initial therapy. An index of high suspicion and detailed assessment is mandatory to make a correct diagnosis and following less invasive surgical treatment.

Laparoscopic Removal of Streak Gonads in Turner Syndrome.

Mandelberger, Adrienne; Mathews, Shyama; Andikyan, Vaagn; Chuang, Linus

To demonstrate the skills necessary for complete resection of bilateral streak gonads in Turner syndrome. Video case presentation with narration highlighting the key techniques used. The video was deemed exempt from formal review by our institutional review board. Turner syndrome is a form of gonadal dysgenesis that affects 1 in 2500 live births. Patients often have streak gonads and may present with primary amenorrhea or premature ovarian failure. Patients with a mosaic karyotype that includes a Y chromosome are at increased risk for gonadoblastoma and subsequent transformation into malignancy. Gonadectomy is recommended for these patients, typically at adolescence. Streak gonads can be difficult to identify, and tissue margins are often in close proximity to critical retroperitoneal structures. Resection can be technically challenging and requires a thorough understanding of retroperitoneal anatomy and precise dissection techniques to ensure complete removal. Laparoscopic approach to bilateral salpingo-oophorectomy of streak gonads. Retroperitoneal dissection and ureterolysis are performed, with the aid of the Ethicon Harmonic Ace, to ensure complete gonadectomy. Careful and complete resection of gonadal tissue in the hands of a skilled laparoscopic surgeon is key for effective cancer risk reduction surgery in Turner syndrome mosaics. Copyright © 2016 AAGL.

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.

Hadassah University Hospital Ein-Karem, Jerusalem, Izrael. Ovarian tissue cryopreservation (OTC) and its future auto-transplantation becomes an alternative for patients to prevent serious damage of ovarian function by oncology treatment. Patient is indicated to OTC in case of high risk of ovarian failure due to planned chemotherapy and impossibility to use other oncofertility techniques. Ovarian tissue harvesting is done by laparoscopy in short-term general anesthesia. After tissue processing the samples are cryopreserved in programmable automatic freezer or by vitrification. The auto-transplantation of ovarian tissue is planned after the complete cure of patient's malignancy. Our workplace doesn't have own experience with tissue transplantation - until now cryopreserved tissue has not yet been utilized by the patients. Clinical experience with this technique gained by our team during academic stay in abroad Israeli clinic is presented. During the years of 2005-2011 the OTC was performed in 19 cancer patients before chemotherapy. In majority of cases, patients suffered from blood or lymph node systemic malignancy (84%). Average age of women was 26 years. The patient set consisted of mostly nulliparous women (88%). Patient's average body mass index was 23,9 kg/m2. The length of systemic chemotherapy averaged 7.1 months. Time from fertility preservation counseling to chemotherapy was not exceeding one week (7.2 days on average). Ovarian tissue harvesting was conducted by laparoscopic surgery in all cases. The length of surgery did not exceed 60 minutes and no surgical complications were observed. The case of ovarian tissue transplantation performed on abroad university settings is discussed. In the consensus of with international guidelines OTC is offered to patients with high risk of ovarian failure doe to cytotoxic oncology treatment. Research in the field of oncofertility is focused on the techniques of in-vitro folliculogenesis in retrieved ovarian tissue.

Between April 1983 and December 1987, we have treated and followed 16 patients at the University of Southern California for adenocarcinoma of the bladder. In 10 patients, the cancer originated from a nonurachal source; all underwent radical cystectomy, bilateral pelvic lymph node dissection, and urinary diversion. The other 6 patients had an apparent urachal origin of their cancer. Half of these patients were treated with radical cystectomy and urinary diversion and half were treated initially with segmental cystectomy. Presenting characteristics (age, sex ratio, and symptoms) were similar for both groups. Three-year adjusted acturial tumor-free survival rates for the two groups were 48 percent and 31 percent, respectively. We advocate an aggressive approach of radical cystectomy, bilateral pelvic lymph node dissection, and urinary diversion for all invasive adenocarcinoma of the bladder, regardless of location.

Laparoscopic ovarian diathermy (LOD) is currently accepted as a successful second-line treatment for ovulation induction (OI) in clomiphene citrate (CC)-resistant women with polycystic ovary syndrome (PCOS). The aim of this study was to test the hypothesis that LOD may be superior to CC as a first-line treatment. The study included 72 anovulatory women with PCOS who were randomized to LOD (n = 36) or CC (n = 36). Women who remained anovulatory after LOD were offered CC. Similarly, women receiving CC who failed to ovulate or conceive were offered LOD. Pregnancy rates were compared between the two groups using chi(2) and odds ratio with 95% confidence interval (OR, 95% CI). After randomization, six women conceived before starting treatment and another patient postponed treatment. The remaining 65 women received the treatment (33 underwent LOD and 32 received CC). After the primary treatment, more pregnancies (44%) occurred in women receiving CC than in those undergoing LOD (27%), although the difference did not reach statistical significance [P = 0.13, OR 2.1 (0.7 - 5.8)]. After adding the second treatment, the pregnancy rate was still higher, but to a less extent, in the CC group [63% versus 52%, P = 0.2, OR 1.6 (0.6 - 4.2)]. LOD is not superior to CC as a first-line method of OI in women with PCOS. The trial is registered with ClinicalTrials.gov with an identifier number NCT00220545.

The aim of this study was to investigate serum and adipocyte mRNA expression of resistin in lean and obese women with polycystic ovary syndrome (PCOS) before and 3 months after laparoscopic ovarian electrocauterization (LOE). Adipose tissue obtained from 12 women with PCOS (six obese and six lean, body mass index > 27 kg m(-1) as threshold point) before and after LOE was analysed. Gene expression of resistin was measured by semi-quantitative RT-PCR. Ten lean, age-matched healthy women served as controls. Both lean and obese women with PCOS had significantly higher fasting and 2 h insulin and homeostasis model insulin resistance index (HOMA(IR)) values and lower fasting glucose-to-insulin ratios (G(0)/I(0)) than did the controls. The serum levels of glucose and insulin and HOMA(IR) were significantly decreased, and the G(0)/I(0) ratio was significantly increased 3 months after LOE. No difference was found in serum resistin levels between controls and either obese or lean women with PCOS before LOE, nor between PCOS patients before and after LOE. However, resistin mRNA expression levels in both lean and obese women with PCOS before LOE were significantly higher than that in controls and were decreased significantly after LOE back to control levels. Local resistin activity may be actively involved in the pathogenesis of PCOS. LOE reduces insulin resistance and down-regulates resistin mRNA expression in lean and obese women with PCOS.

A 35-year-old woman presented with an abdominal mass found incidentally on an ultrasound scan. On examination, the uterus was mobile and 14 weeks in size. Further imaging showed a large subserosal pedunculated fibroid, and she was counselled for laparoscopic myomectomy, morcellation in a bag, kept in open view. Intraoperatively, the mass was noted to be arising from the right ovarian ligament instead of the uterus, and decision was made to convert to open surgery. This case highlights important issues of consent-taking preoperatively and critical points to note regarding change in operative consent intraoperatively. This also highlights the importance of multidisciplinary cooperation as the decision had to be made with inputs made from gynae-oncology and pathology. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

Treatment strategies for the infertile polycystic ovary syndrome patient.

PubMed

Tannus, Samer; Burke, Yechiel Z; Kol, Shahar

2015-11-01

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age. Infertility is a prevalent presenting feature of PCOS, and approximately 75% of these women suffer infertility due to anovulation. Lifestyle modification is considered the first-line treatment and is associated with improved endocrine profile. Clomiphene citrate (CC) should be considered as the first line pharmacologic therapy for ovulation induction. In women who are CC resistant, second-line treatment should be considered, as adding metformin, laparoscopic ovarian drilling or treatment with gonadotropins. In CC treatment failure, Letrozole could be an alternative or treatment with gonadotropins. IVF is considered the third-line treatment; the 'short', antagonist-based protocol is the preferred option for PCOS patients, as it is associated with lower risk of developing ovarian hyperstimulation syndrome (specifically by using a gonadotropin--releasing hormone agonist as ovulation trigger), but with comparable outcomes as the long protocol.

Robotic-assisted laparoscopic surgery: recent advances in urology.

2014-10-01

The aim of the present review is to summarize recent developments in the field of urologic robotic surgery. A nonsystematic literature review was performed to retrieve publications related to robotic surgery in urology and evidence-based critical analysis was conducted by focusing on the literature of the past 5 years. The use of the da Vinci Surgical System, a robotic surgical system, has been implemented for the entire spectrum of extirpative and reconstructive laparoscopic kidney procedures. The robotic approach can be applied for a range of adrenal indications as well as for ureteral diseases, including benign and malignant conditions affecting the proximal, mid, and distal ureter. Current evidence suggests that robotic prostatectomy is associated with less blood loss compared with the open surgery. Besides prostate cancer, robotics has been used for simple prostatectomy in patients with symptomatic benign prostatic hyperplasia. Recent studies suggest that minimally invasive radical cystectomy provides encouraging oncologic outcomes mirroring those reported for open surgery. In recent years, the evolution of robotic surgery has enabled urologic surgeons to perform urinary diversions intracorporeally. Robotic vasectomy reversal and several other robotic andrological applications are being explored. In summary, robotic-assisted surgery is an emerging and safe technology for most urologic operations. The acceptance of robotic prostatectomy during the past decade has paved the way for urologists to explore the entire spectrum of extirpative and reconstructive urologic procedures. Cost remains a significant issue that could be solved by wider dissemination of the technology. Copyright © 2014 American Society for Reproductive Medicine. Published by Elsevier Inc.

To investigate the development and management of chylous leakage after laparoscopic retroperitoneal lymphadenectomy. From July 2006 to September 2013, 13 cases of chylous leakage after the laparoscopic lymphadenectomy (6 cases of renal cell carcinoma, 4 cases of gastric cancer, 2 cases of ovarian cancer, 1 case of endometrial cancer) were studied to analyze the occurrence, development and management of chylous leakage. In 3 cases (2 cases of renal cell carcinoma, 1 case of gastric cancer) massive amount of milky fluid drainage was be seen after the first two days post operation. Dietary intervention, TPN (total parenteral nutrition), somatostatin therapy, maintenance of continuous drainage helped to successfully manage the condition in about 1 month duration. In the remaining 10 cases, chylous leakage appeared after restoring normal diet. Managed with changes in diet and maintenance of unobstructed drainage, they were cured in about 2 weeks after treatment. There was significant reduction in drain output, ultrasonography did not reveal presence of free fluid collection in abdomen, and the patients were in good condition without signs and symptoms of infections. Chylous leakage is a rare complication of retroperitoneal lymph node dissection. Surgeons should be familiar with laparoscopic techniques, relevant anatomy and be aware of the fact that the effect of CO2 pressure and use of ultrasonic knife to occlude the lymphatic vessel can transiently block the leakage making the surgeon overlook them. Routine placement of indwelling drainage tube, immediate diagnosis, dietary modification, TPN, somatostatin and drainage are the modalities of conservative management.

Retrospective analysis of 52 selected patients with recurrent ovarian cancer undergoing secondary cytoreduction by laparoscopy (9), laparotomy (33) or robotics (10) between January 2006 and December 2010. Comparison was made by a total of 21 factors including age, BMI, number of previous surgeries, tumor type and grade, number of procedures, and 15 types of procedures performed at secondary cytoreduction. For all patients, the mean operating time was 213.8 min, mean blood loss 657.4 ml; and mean hospital stay 7.5 days. Complete debulking was achieved in 75% of patients. Postoperative complications were noted in 36.5% of patients. Overall and progression-free survival at 3-years were 58.8% and 34.1%, respectively. Laparoscopy and robotics had reduced blood loss and hospital stay, while no differences were observed among the three groups for operating time, complications, complete debulking, and survival. Selected patients with recurrent ovarian cancer benefit from a laparoscopic or robotic secondary cytoreduction without compromising survival. Robotics and laparoscopy provide similar perioperative outcomes, and reduced blood loss and shorter hospital stay as compared to laparotomy. Laparotomy seems preferable for patients with widespread peritoneal implants, multiple sites of recurrence, and/or extensive adhesions. Copyright © 2013 Elsevier Inc. All rights reserved.

To study whether slush nitrogen vitrification improves the preservation of human ovarian tissue. Control vs. treatment study. University research laboratory. Ovarian biopsies collected from nine women (aged 14-35 years) during laparoscopic surgery for benign gynecologic conditions. None. Ovarian cortical strips of 2 × 5 × 1 mm were vitrified with liquid or slush nitrogen. Fresh and vitrified cortical strips were analyzed for cryodamage and viability under light, confocal, and transmission electron microscopy. Compared with liquid nitrogen, vitrification with slush nitrogen preserves [1] follicle quality (grade 1 follicles: fresh control, 50%; liquid nitrogen, 27%; slush nitrogen, 48%); [2] granulosa cell ultrastructure (intact cells: fresh control, 92%; liquid nitrogen, 45%; slush nitrogen, 73%), stromal cell ultrastructure (intact cells: fresh control, 59.8%; liquid nitrogen, 24%; slush nitrogen, 48.7%), and DNA integrity (TUNEL-positive cells: fresh control, 0.5%; liquid nitrogen, 2.3%; slush nitrogen, 0.4%); and [3] oocyte, granulosa, and stromal cell viability (oocyte: fresh control, 90%; liquid nitrogen, 63%; slush nitrogen, 87%; granulosa cells: fresh control, 93%; liquid nitrogen, 53%; slush nitrogen, 81%; stromal cells: fresh control, 63%; liquid nitrogen, 30%; slush nitrogen, 52%). The histology, ultrastructure, and viability of follicles and stromal cells are better preserved after vitrification with slush nitrogen compared with liquid nitrogen.

Surgery remains the mainstay in the diagnosis and management of endometriosis. The number of surgeries performed for endometriosis worldwide is ever increasing, however do we have evidence for improvement of infertility after the surgery and do we exaggerate the magnitude of effect of surgery when we counsel our patients? The management of patients who failed the surgery could be by repeat surgery or assisted reproduction. What evidence do we have for patients who fail assisted reproduction and what is their best chance for achieving pregnancy? In this study we reviewed the evidence-based practice pertaining to the outcome of surgery assisted infertility associated with endometriosis. Manuscripts published in PubMed and Science Direct as well as the bibliography cited in these articles were reviewed. Patients with peritoneal endometriosis with mild and severe disease were addressed separately. Patients who failed the primary surgery and managed by repeat or assisted reproduction technology were also evaluated. Patients who failed assisted reproduction and managed by surgery were also studied to determine of the best course of action. In patients with minimal and mild pelvic endometriosis, excision or ablation of the peritoneal endometriosis increases the pregnancy rate. In women with severe endometriosis, controlled trials suggested an improvement of pregnancy rate. In women with ovarian endometrioma 4 cm or larger ovarian cystectomy increases the pregnancy rate, decreases the recurrence rate, but is associated with decrease in ovarian reserve. In patients who have failed the primary surgery, assisted reproduction appears to be significantly more effective than repeat surgery. In patients who failed assisted reproduction, the management remains to be extremely controversial. Surgery in expert hands might result in significant improvement in pregnancy rate. In women with minimal and mild endometriosis, surgical excision or ablation of endometriosis is recommended as first line with doubling the pregnancy rate. In patients with moderate and severe endometriosis surgical excision also is recommended as first line. In patients who failed to conceive spontaneously after surgery, assisted reproduction is more effective than repeat surgery. Following surgery, the ovarian reserve may be reduced as determined by Anti Mullerian Hormone. The antral follicle count is not significantly reduced. In women with large endometriomas > 4 cm the ovarian endometrioma should be removed. In women who have failed assisted reproduction, further management remains controversial in the present time.

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.

Health related quality of life after radical cystectomy and ileal conduit is not well quantified at the population level. We evaluated health related quality of life in patients with bladder cancer compared with noncancer controls and patients with colorectal cancer using data from SEER (Surveillance, Epidemiology and End Results)-MHOS (Medicare Health Outcomes Survey). SEER-MHOS data from 1998 to 2013 were used to identify patients with bladder cancer and those with colorectal cancer who underwent extirpative surgery with ileal conduit or colostomy creation, respectively. A total of 166 patients with bladder cancer treated with radical cystectomy were propensity matched 1:5 to 830 noncancer controls and compared with 154 patients with colorectal cancer. Differences in Mental and Physical Component Summary scores as well as component subscores were determined between patients with bladder cancer, patients with colorectal cancer and noncancer controls. SEER-MHOS patients were more commonly male and white with a mean ± SD age of 77 ± 6 years. Patients treated with radical cystectomy had significantly lower Physical Component Summary scores, select physical subscale scores and all mental subscale scores compared with noncancer controls. These findings were similar in the subset of 40 patients treated with radical cystectomy who had available preoperative and postoperative survey data. Global Mental Component Summary scores did not differ significantly between the groups. No significant differences were observed in global Mental Component Summary, Physical Component Summary or subscale scores between patients with bladder cancer and patients with colorectal cancer. Patients with bladder cancer who undergo radical cystectomy have significant declines in multiple components of physical and mental health related quality of life vs noncancer controls, which mirror those of patients with colorectal cancer. Further longitudinal study is required to better codify the effectors of poor health related quality of life after radical cystectomy to improve patient expectations and outcomes.

Ultrasound diagnostic of mesonephric paraovarian cyst - case report

PubMed Central

Bohîlțea, RE; Cîrstoiu, MM; Turcan, N; Ionescu, CA

2016-01-01

Paraovarian cysts are a rare pathology, constituting 10-20% of the adnexal masses. The origin can be represented by paramesonephric ducts (Hydatid cysts of Morgagni), vestiges of mesonephric ducts also represented by mesothelium, or neoplastic (cystadenomas or cystadenofibromas) that are mostly benign. Borderline or malignant paraovarian tumors are encountered less often. This article presents a case of paraovarian cyst in a 37-year-old patient, with a history of 2 pregnancies, completed by cesarean. The patient sought medical attention for an asymptomatic voluminous ovarian cyst, detected in a routine ultrasound scan. Laboratory tests and tumor markers were within normal limits. Transvaginal ultrasound and color Doppler revealed a cystic adnexal mass with 10 cm transonic, smooth, homogeneous content, avascular walls with no internal papillary projections, with a “hyperechoic line” sign of delimitation from the ovarian capsule, mostly visible when the adnexa was mobilized. The diagnostic and curative laparoscopic surgery was successful, followed by a quick recovery. The histopathological exam confirmed the benignity and the origin of the paraovarian cyst. The case was discussed in the context of the literature review concerning this pathology, drawing attention to the real possibility of differentiating ovarian from paraovarian cysts by ultrasound.

Treatment of infertility in women with polycystic ovary syndrome: approach to clinical practice

PubMed Central

Melo, Anderson Sanches; Ferriani, Rui Alberto; Navarro, Paula Andrea

2015-01-01

Polycystic ovary syndrome represents 80% of anovulatory infertility cases. Treatment initially includes preconception guidelines, such as lifestyle changes (weight loss), folic acid therapy to prevent the risk of fetal neural tube defects and halting the consumption of tobacco and alcohol. The first-line pharmacological treatment for inducing ovulation consists of a clomiphene citrate treatment for timed intercourse. The second-line pharmacological treatment includes the administration of exogenous gonadotropins or laparoscopic ovarian surgery (ovarian drilling). Ovulation induction using clomiphene citrate or gonadotropins is effective with cumulative live birth rates of approximately 70%. Ovarian drilling should be performed when laparoscopy is indicated; this procedure is typically effective in approximately 50% of cases. Finally, a high-complexity reproduction treatment (in vitro fertilization or intracytoplasmic sperm injection) is the third-line treatment and is recommended when the previous interventions fail. This option is also the first choice in cases of bilateral tubal occlusion or semen alterations that impair the occurrence of natural pregnancy. Evidence for the routine use of metformin in infertility treatment of anovulatory women with polycystic ovary syndrome is not available. Aromatase inhibitors are promising and longer term studies are necessary to prove their safety. PMID:26602525

Inherited mutations in BRCA1 and BRCA2 lead to 20-50% lifetime risk of ovarian, tubal, or peritoneal carcinoma. Clinical recommendations for women with these genetic mutations include the prophylactic removal of ovaries and fallopian tubes by age 40 after child-bearing. Recent findings suggest that many presumed ovarian or peritoneal carcinomas arise in fallopian tube epithelium. Although survival rate is <90% when ovarian cancer is detected early (Stage_I), 70% of women have advanced disease (Stage_III/IV) at presentation when survival is less than 30%. Over the years, effective early detection of ovarian cancer has remained elusive, possibly because screening techniques have mistakenly focused on the ovary as origin of ovarian carcinoma. Unlike ovaries, the fallopian tubes are amenable to direct visual imaging without invasive surgery, using access through the cervix. To develop future screening protocols, we investigated using our 1.2- mm diameter, forward-viewing, scanning fiber endoscope (SFE) to image luminal surfaces of the fallopian tube before laparoscopic surgical removal. Three anesthetized human subjects participated in our protocol development which eventually led to 70-80% of the length of fallopian tubes being imaged in scanning reflectance, using red (632nm), green (532nm), and blue (442nm) laser light. A hysteroscope with saline uterine distention was used to locate the tubal ostia. To facilitate passage of the SFE through the interstitial portion of the fallopian tube, an introducer catheter was inserted 1- cm through each ostia. During insertion, saline was flushed to reduce friction and provide clearer viewing. This is likely the first high-resolution intraluminal visualization of fallopian tubes.

Transvaginal ultrasound-guided follicle aspiration (TVA) is performed clinically but there is little information available on complications associated with this procedure. It is possible that TVA is associated with damage to the ovary and may induce peritonitis or peritoneal adhesions. This study was conducted to determine the effect of repeated TVA on mare health and ovarian status. Thirty-two mares were used for oocyte recovery via repeated TVA over a 3 year period; different mares were used each year. In Year 1, ovarian status was monitored in 11 mares by transrectal palpation and ultrasonography. In Year 2, 6 of 11 mares underwent abdominocentesis and were examined by laparoscopy after one TVA and again after multiple TVAs. In Year 3, 10 mares underwent multiple TVAs with either a 15 or a 12 gauge needle and the ovaries were removed for examination. Four hundred and twenty-seven aspiration sessions (390 via TVA and 37 via needle placement through the flank) and 3202 follicle punctures (3161 TVA and 41 flank) were performed. One mare developed an ovarian abscess. Transient rectal bleeding was evident after 16% of TVA sessions. No adhesions were found on laparoscopic or gross examination of ovaries and there were minimal changes on histological evaluation. Follicle aspiration carries a small possibility (< 0.5%) of ovarian abscess formation. There is a possibility of rectal abrasion or puncture but little gross or histological damage to the ovary. These results provide a basis for using prophylactic administration of antibiotics after TVA and for advising mare owners of the rare but potential complications associated with the procedure.

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.

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 surgery for treatment of primary localized bladder amyloidosis: could prostate-sparing robot-assisted cystectomy with intracorporeal urinary diversion be an option?

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.

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.

To evaluate the effectiveness of ultrasound-guided transversus abdominis plane (TAP) and rectus sheath (RS) blocks in pain management and recovery after gynecological single-incision laparoscopic surgery (SILS). Abilateral TAP block (Group A, n = 9), bilateral TAP and RS blocks (Group B, n = 10), and a bilateral RS block (Group C, n = 9) with 40 ml ropivacaine per patient were conducted in 28 patients undergoing SILS for ovarian tumors. A pain score and walking distance in a 6-minute walk test (6MWT) were examined. Pain scores were significantly lower on postoperative day (POD) 3 than on POD 1 in Groups B (p = 0.03) and C (p = 0.02). The walking distance on POD 3 was comparable with that before surgery in Group C (p = 0.75), but shorter in Groups A (p = 0.004) and B (p = 0.02). The RS block alone was the most effective in relieving pain and accelerating general recovery after gynecological SILS.

Laparoscopic evaluation, comprehensive surgical staging for early ovarian cancer, or tumour debulking for advanced stage ovarian cancer. To optimize conservative versus operative management of women with possible ovarian malignancy and to optimize the involvement of gynaecologic oncologists in planning and delivery of treatment. Published literature was retrieved through searches of PubMed or MEDLINE, CINAHL, and the Cochrane Library, using appropriate controlled vocabulary and key words. Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. Grey (unpublished) literature was identified by searching the web sites of health technology assessment and health technology assessment-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. 1. Primary care physicians and gynaecologists should always consider the possibility of an underlying ovarian cancer in patients in any age group who present with an adnexal or ovarian mass. (II-2B) 2. Appropriate workup of a perimenopausal or postmenopausal woman presenting with an adnexal mass should include evaluation of symptoms and signs suggestive of malignancy, such as persistent pelvic/abdominal pain, urinary urgency/frequency, increased abdominal size/bloating, and difficulty eating. In addition, CA125 measurement should be considered. (II-2B) 3. Transvaginal or transabdominal ultrasound examination is recommended as part of the initial workup of a complex adnexal/ovarian mass. (II-2B) 4. Ultrasound reports should be standardized to include size and unilateral/bilateral location of the adnexal mass and its possible origin, thickness of septations, presence of excrescences and internal solid components, vascular flow distribution pattern, and presence or absence of ascites. This information is essential for calculating the risk of malignancy index II score to identify pelvic mass with high malignant potential. (IIIC) 5. Patients deemed to have a high risk of an underlying malignancy should be reviewed in consultation with a gynaecologic oncologist for assessment and optimal surgical management. (II-2B).

To study possible associations among endometriosis, pelvic infectious disease, and ART. Retrospective cohort analysis over 4 consecutive years, based on medical records and insurance coding in a tertiary endometriosis reference center. Tertiary university-based reference center for endometriosis. We retrieved all charts carrying the diagnoses infectious process and endometriosis in 2009-2012. Each chart was individually analyzed for categorization of the infectious episode and determining whether ART had been performed. Hospitalization for acute infection in women with known endometriosis and possible past ART. Retrospective insurance codes-triggered chart analysis. Ten patients were admitted for an acute infection with fever, acute abdomen syndrome, elevated white blood cell count, and adnexal mass. Three women had oocyte retrieval, and an endometrioma was present 16, 57, and 102 days earlier. In one patient, the complication occurred 37 days after a cesarean section without prior ART. In the remaining six cases tubo-ovarian abscesses (TOAs) occurred spontaneously in endometriosis women who never had ART. Medical treatment succeeded in only two patients, and the remaining eight needed laparoscopic drainage. In 6 out of those 8 cases, laparoscopic drainage was a second-stage measure justified by failure to respond to antibiotic therapy. Our data indicate that some putative complications of ART and endometrioma may actually not be linked to ART, but rather constitute sporadic occurrences in endometriosis. Furthermore, TOAs occurring in women with endometriosis are best treated by early surgical drainage together with intravenous antibiotics. Copyright © 2016 American Society for Reproductive Medicine.

Forty superovulated dairy ewes of the Greek Chios breed were used in an experiment to evaluate the efficiency of laparoscopic intrauterine insemination on fertilization and embryo recovery rates as well as embryo quality. Estrus was synchronized by intravaginal progestagen impregnated sponges and superovulation was induced by administration of 8.8 mg o-FSH i.m. following a standard 8 dose protocol. A small volume (0.3 mL) of diluted fresh ram semen was deposited in each uterine horn 24 to 28 h after onset of the estrus by a laparoscopic technique. The animals were allocated randomly into two groups (Group A and B) of 20 animals each. In Group A, embryos were recovered 18 to 24 h after the intrauterine insemination and in Group B on Day 6. The average number of corpora lutea was 12.8 +/- 1.2 and 11.5 +/- 1.1 (+/- SEM); the overall embryo recovery was 66.4% and 57% and the percentage of recovered fertilized ova was 81% and 82.8% in Groups A and B, respectively. More fertilized ova were collected per ewe from Group A (P < or = 0.1). Results indicated that in Chios breed, superovulation using homologous FSH combined with laparoscopic AI leads to good ovarian response with satisfactory results in fertilization, embryo recovery and quality of embryos. This could lead to improved and more efficient methods for obtaining large numbers of high quality oocytes and embryos for embryo transfer programs which could contribute to genetic improvement and increase of the population size.

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

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 report a case of hyperandrogenism attributable to the presence of an adrenal adenoma secreting dehydroepiandrosterone sulfate (DHEA-S) and an ovarian Sertoli-Leydig cell tumor secreting testosterone in a postmenopausal woman. The laboratory, radiologic, and pathologic findings in our case are described. In addition, the pertinent literature is reviewed. A 56-year-old woman presented with a history of gradual increase in facial and body hair, scalp hair loss, male pattern baldness, and deepening of her voice, beginning a few years after spontaneous menopause at age 49 years. She had hypertension, obesity, and type 2 diabetes mellitus. Laboratory tests showed elevated levels of total testosterone (348 ng/dL) and DHEA-S (2,058 microg/dL), and a left adrenal tumor (3 by 4 cm) was detected on abdominal computed tomographic scan. Laparoscopic left adrenalectomy was performed, and the pathologic diagnosis was adrenal adenoma. The DHEA-S returned to normal levels, but the serum testosterone concentration remained elevated. Transvaginal ultrasonography disclosed an ovarian tumor. Bilateral oophorectomy was performed, and an ovarian Sertoli-Leydig cell tumor was diagnosed. The hormonal and clinical picture normalized after this surgical intervention. After extensive review of the literature, we believe that this is the first reported case of a coincidental DHEA-S-secreting adrenal adenoma and a testosterone- secreting ovarian Leydig cell tumor causing signs of virilization.

We investigated the prediction of the ovarian response to superovulation using progesterone (P4) determination in Chios ewes. During the estrus period. estrus synchronization and multiple ovulations were induced in 100 non-pregnant, non-lactating Chios ewes by a combination of FGA-impregnated intravaginal sponges and 8.8 mg of ovine FSH. Laparoscopic insemination was conducted 24-28 h after the onset of estrus. A concentration of P4 was determined on Day 5 of the estrous cycle and on Day 6 the ovarian response was evaluated by counting the corpus lutea (CL); subsequently, embryo collection was performed. According to the response of their ovaries, ewes were allocated into four groups: A (n = 30); B (n = 37); C (n = 22); D (n = 11), with minimal (0-3 CL), moderate (4-8 CL), good (9-13 CL) or extreme (> 13 CL) ovarian response, respectively. In groups C and D, the mean blood serum P4 concentration (23.2 and 27.3 ng/ml, respectively) was higher (P < 0.001) than that in groups A and B (4.6 and 13.1 ng/ml, respectively); no difference was detected in blood P4 concentration between groups C and D. A strong linear relation (F < 0.00005) was found between blood P4 concentration and the number of CL, as well as between blood P4 and a dummy variable corresponding to poor (< 4 CL) or moderate/good/extreme ovarian response (>3 CL). Our results indicate that based on blood P4 measurement, it is feasible to identify ewes that should show the highest embryo recovery, while it is impossible to predict the exact number of CL formed.

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.

Orgasm associated incontinence, that is the inadvertent leakage of urine at orgasm, has received little attention in the literature. We evaluated the rate of occurrence of orgasm associated incontinence following radical pelvic surgery as well as its associated factors and predictors. From January 2005 to March 2006, 696 patients were evaluated for post-radical pelvic surgery sexual dysfunction. A database was created, and descriptive statistics, chi-square analysis and logistic regression analysis were used to evaluate associated factors and predictors. Of 475 patients 96 (20%) reported orgasm associated incontinence following radical pelvic surgery. The incidence was significantly less in the cystoprostatectomy group than in the open and laparoscopic radical prostatectomy groups (p <0.05). Orgasm associated incontinence was more commonly found within 12 months following surgery vs greater than 12 months (RR 0.81, 95% CI 0.72-0.92, p <0.01) and in patients with orgasm associated pain (RR 1.09, 95% CI 1.01-1.16, p <0.01) and penile length loss (RR 1.32, 95% CI 1.09-1.59, p <0.01). On multivariate analysis all factors associated on univariate analyses remained predictive. Orgasm associated incontinence was not associated with patient age, the degree of nerve sparing, surgical margin status, seminal vesicle or lymph node involvement, preoperative erectile function, nocturnal erections, libido level or daytime continence. Orgasm associated incontinence occurs in a fifth of men (96 of 475) following radical pelvic surgery. The incidence of orgasm associated incontinence is greater with radical prostatectomy than with radical cystectomy and it is unrelated to the type of prostatectomy performed (open vs laparoscopic). Orgasm associated incontinence is more likely to be reported within year 1 following surgery and in men who complain of orgasmic pain and/or penile shortening.

The high rate of recurrence after apparently complete surgery and/or complete clinical response to chemotherapy implies that most patients have undetected minimal residual disease. Novel techniques such as laparoscopic or laparotomic fluorescence may prove to be crucial in reassessing the definition of primary outcome in ovarian cancer management. For this purpose, the importance of fluorescence in the peroperative detection of human ovarian adenocarcinoma cells has to be validated in animal models prior to be used in clinic by determining its efficiency in detecting infra-millimetric tumor metastases. In the preclinical data presented, a fluorescent RAFT-(cRGD)4 tracer molecule (AngioStamp(®)) with a very high affinity for the αvβ3 integrin was used. Infrared fluorescence was visualized with Fluobeam(®), an open fluorescent imaging system that could potentially be used in peroperative conditions in the future. We showed that this novel technique allowed the specific detection of residual tumor deposits and inframillimetric metastases in mice and dogs.

ABSTRACT As the only domesticated species known to exhibit both induced and spontaneous ovulation, the cat is a model for understanding the nuances of ovarian control. To explore ovarian sensitivity to exogenous gonadotropins and the influence of progestin priming, we conducted a study of queens that were down-regulated with oral progestin or allowed to cycle normally, followed by low or high doses of equine chorionic gonadotropin (eCG) and human chorionic gonadotropin (hCG). Our metrics included 1) fecal steroid metabolite profiles before and after ovulation induction, 2) laparoscopic examination of ovarian follicles and corpora lutea (CL) on Days 2 and 17 (Day 0 = hCG administration), and 3) ovariohysterectomy (Day 17) to assess CL progesterone concentrations, morphometrics, and histology. Reproductive tracts from time-matched, naturally mated queens (n = 6) served as controls. Every progestin-primed cat (n = 12) produced the desired response of morphologically similar, fresh CL (regardless of eCG/hCG dose) by Day 2, whereas 41.7% of unprimed counterparts (n = 12) failed to ovulate or had variable-aged CL suggestive of prior spontaneous ovulation (P < 0.05). The ovarian response to low, but not high, eCG/hCG was improved (P < 0.05) in primed compared to unprimed cats, indicating increased sensitivity to gonadotropin in the progestin-primed ovary. Progestin priming prevented hyperelevated fecal steroid metabolites and normalized CL progesterone capacity, but only when combined with low eCG/hCG. However, priming failed to prevent ancillary CL formation, smaller CL mass, or abnormal luteal cell density, which were common to all eCG/hCG-treated cats. Thus, the domestic cat exposed to eCG/hCG produces CL with structural and functional aberrations. These anomalies can be partially mitigated by progestin priming, possibly due to a protective effect of progestin associated with enhanced ovarian sensitivity to gonadotropins. PMID:23100619

Late recurrent urothelial carcinoma in the Studer neobladder: conversion to continent reservoir

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 evaluate fertility outcomes in infertile women with severe endometriosis (The revised American Fertility Society classification [AFS] 3-4) and repeated IVF failures, who underwent surgery due to exacerbation of endometriosis-related symptoms. Retrospective cohort study. University hospital. All women who failed IVF treatment before surgery and who underwent laparoscopic surgery for severe endometriosis between January 2006 and December 2014. All patients were operated by highly skilled surgeons specializing in laparoscopic surgery for advanced endometriosis. Only patients with evidence of endometriosis in the pathology specimens were included in this study. Delivery rate after surgery. Seventy-eight women were included in the present study. All women were diagnosed with severe endometriosis during surgery (AFS 3-4) and all women had experienced failed IVF treatments before surgery. All women were symptomatic before their surgery. After surgical treatment 33 women (42.3%) delivered. Three women (9%) conceived spontaneously and all other women conceived after IVF treatment. Women who delivered were younger (32.5 [±4.1] years vs. 35.5 [±3.8] years), were less often diagnosed with diminished ovarian reserve before surgery (6% vs. 28.8%), and were more often diagnosed with normal uterine anatomy (by preoperative transvaginal ultrasound and during operation). In addition, performing salpingectomy during surgery was associated with a trend of improvement in delivery rates after surgery (70% in women who delivered vs. 51% in women who failed to deliver). Symptomatic women with severe endometriosis and repeated IVF implantation failures may benefit from extensive laparoscopic surgery when performed by an experienced multidisciplinary surgical team to improve IVF outcome.

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.

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

To find out different causes of female infertility with diagnostic laparoscopy and their comparative frequency in primary and secondary infertility. A case series. Department of Obstetric and Gynaecology, Liaquat University Hospital (LUH), Hyderabad, rom January 2006 to December 2007. All infertile women underwent diagnostic laparoscopy for primary and secondary infertility during the study period were included. Couples who had not lived together for at least 12 months, and those with male factor infertility were excluded. Data were collected on a proforma, and analysed on SPSS package for windows version 10. Frequencies were calculated for laparoscopic findings regarding primary and secondary infertility. Fifty infertile women underwent laparoscopy during the study period, 32 (64%) had primary infertility while 18 (36%) secondary infertility. Eight (25.0%) patients with primary and 2 (11.1%) patients with secondary infertility had no visible abnormality. The common finding was tubal blockage in 7 (21.9%) and 6 (33.3%) cases of primary and secondary infertility respectively. Five (15.6%) cases of primary infertility were detected as polycystic ovaries (PCO) which was not found in cases of secondary infertility. Endometriosis was found in 4 (12.5%) cases with primary infertility and 2 (11.1%) cases with secondary infertility. Pelvic inflammatory disease (PID) was found in 1 (3.1%) and 2 (16.7%) cases of primary and secondary infertility respectively. Peritubal and periovarian adhesions were detected in 2 (6.3%) cases with primary infertility and 4 (22.2%) cases with secondary infertility. Fibriod was found in 2 (6.3%) and 1 (5.6%) cases of primary and secondary infertility respectively. Ovarian cyst detected in 2 (6.3%) cases with primary infertility while none was found in cases of secondary infertility. Most common causes responsible for infertility were tubal occlusion, endometriosis, peritubal and periovarian adhesions. Ovarian causes were seen in primary infertility only.

A systematic review and meta-analysis of eleven RCTs. Women undergoing operative LESS and MPL gynecologic procedure (hysterectomy, cystectomy, salpingectomy, salpingo-oophorectomy, myomectomy). Outcomes evaluated were as follows: postoperative overall morbidity, postoperative pain evaluation at 6, 12, 24 and 48 h, cosmetic patient satisfaction, conversion rate, body mass index (BMI), operative time, blood loss, hemoglobin drop, postoperative hospital stay. Eleven RCTs comprising 956 women with gynecologic surgical disease randomized to either LESS (477) or MPL procedures (479) were analyzed systematically. The LESS approach is a surgical procedure with longer operative and better cosmetic results time than MPL but without statistical significance. Operative outcomes, postoperative recovery, postoperative morbidity and patient satisfaction are similar in LESS and MPL. LESS may be considered an alternative to MPL with comparable feasibility and safety in gynecologic operative procedures. However, it does not offer the expected advantages in terms of postoperative pain and cosmetic satisfaction.

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 ?

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.

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.

Borderline ovarian tumors (BOTs) represent 10-20% of all epithelial ovarian malignancies. Most of them are comparable to benign cysts but a high-risk group has been recognized. The aim of the study was to analyze different follow-up strategies in high-risk patients. Patients with BOT treated at our institution from 1992 to 2011 were retrospectively reviewed. Clinicopathological features influencing prognosis were analyzed and two different follow-up strategies compared [6-month laparoscopic look (LPS-look): group A vs. ultrasound/CA-125 evaluation: group B]. 70 patients with high-risk BOTs were identified. After a median progression-free survival (PFS) of 43 months, 27% of patients experienced recurrences. Six months after diagnosis, 26 high-risk patients were submitted to LPS-look: at surgery, 6 out of 10 patients presenting evidence of disease were optimally debulked while in the remaining 4, only biopsies were performed. No difference in PFS was registered between group A and B patients, nevertheless a significant increase in PFS was registered among completely versus incompletely debulked patients with evidence of disease at laparoscopy. Clinical follow-up remains the gold standard for BOTs. These very preliminary data seem to suggest that LPS-look may have an impact on the secondary PFS in a subgroup of high-risk patients. © 2014 S.

Tayloe, J

1980-09-01

This report comprises an analysis of the results of 201 laparoscopic sterilizations performed at Beaufort County Hospital for an 18-month period and the follow-up of these patients for 2 years. Patients ranged in age from 19-45 years (mean, 32.2). Average parity was 2.7, ranging from 0-14. Of the 201 patients, 173 were white and 28 black. 1% of the sterilization attempts failed (n=2 cases). 1 failure occurred in a woman with a previous appendectomy, due to adhesions, and the other patient failure had a history of abdominal gunshot wounds in which she sustained an omental laceration; both women underwent laparotomy and then were sucessfully sterilized via Pomeroy technique. During the 2-year follow-up, 144 of the original 201 were available. 2 of these subjects subsequently became pregnant. 17 gynecologic procedures were later performed on 15 patients. 6 patients had dilatation and curettage for menstrual irregularity, 2 of whom underwent hysterectomy. 6 other patients also had hysterectomy, making a total of 8 of 201 patients. Symptomatic pelvic relaxation (3), severe dysplasia of the cervix (1), a large ovarian cyst with dysmenorrhea and dyspareunia (1), and severe dysmenorrhea and menorrhagia (1) were the other indications for hysterectomy among these sterilization patients. The author points out that the rate of 8 hysterectomies per 201 cases in only 2 years points to an even higher rate of hysterectomy subsequent to laparoscopic sterilization than previously suspected.

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.

Young women with endometrial cancer (EC) have an increased risk of synchronous ovarian cancer. The prognosis of women with synchronous endometrial and ovarian cancer (SEOC) is good. A high proportion of affected women have hereditary non-polyposis colon cancer syndrome (HNPCC). We present the case of a 45-year-old woman with histologically proven endometrioid adenocarcinoma of the endometrium (pT1B, G2, R0 without lymphovascular space invasion). She underwent laparoscopic hysterectomy, bilateral salpingo-oophorectomy, and pelvic lymphadenectomy. Final histology revealed a synchronous bilateral endometrioid ovarian cancer (pT1A, G2, R0). HNPCC analysis by immunohistochemistry showed no microsatellite instability in MSH2, MSH6, MLH1, and PMS2. No adjuvant therapy was administered, clinical follow-up with regular gynecological examinations was recommended. In a systematic literature review, 2,904 cases of women with SEOC were identified with 1,035 (36%) of them being premenopausal or <50 years of age. The proportion of women with SEOC among all reported EC cases was 842/23,498 (3%) and the proportion of young women with SEOC among all reported EC cases was 261/23,498 (1%). In summary, microsatellite instability and subsequent mutations in mismatch repair genes compatible with HNPCC were identified in 6/15 (40%) women analyzed. The mean recurrence-free and overall survival times of young women with SEOC were 1.9 (min 0.2, max 3) and 4.0 (min 0.2, max 22.1) years, respectively. Young women with EC have a high risk of synchronous ovarian cancer. Thus, in young women with EC, bilateral salpingo-oophorectomy or careful histological assessment of both ovaries are recommended in order to confirm or rule out SEOC. HNPCC testing should be offered to all women. Copyright© 2017, International Institute of Anticancer Research (Dr. George J. Delinasios), All rights reserved.

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.

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.

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

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.

Ovaries of the seasonally-breeding snow leopard (Uncia uncia) were examined to determine whether they were responsive to exogenous gonadotrophins throughout the year. The potential of laparoscopic artificial insemination (AI) also was assessed for producing offspring. During the non-breeding, pre-breeding, breeding and post-breeding seasons, females (n = 20) were treated with a standardized, dual-hormone regimen given intramuscularly (600 I.U. of equine chorionic gonadotrophin followed 80-84 h later with 300 I.U. of human chorionic gonadotrophin (hCG)). Laparoscopy was performed 45-50 h after administration of hCG, and all ovarian structures were described. Females with fresh corpora lutea (CL) were inseminated, and anovulatory females were subjected to follicular aspiration to examine oocyte quality. Snow leopards responded to exogenous gonadotrophins throughout the year. Mean number of total ovarian structures (distinct follicles mature in appearance plus CL) did not differ (P > or = 0.05) with season, but the proportion of CL: total ovarian structures was greater (P < 0.01) for the breeding season compared with all other seasons. The proportion of females ovulating was greater (P < 0.05) during the breeding and post-breeding seasons than during the pre-breeding and non-breeding seasons respectively. No Grade-1 quality oocytes were recovered from follicles of anovulatory females. Serum concentrations of oestradiol-17 beta appeared elevated in all females, and neither oestradiol-17 beta concentrations nor progesterone concentrations differed (P > or = 0.05) among seasons. Of 15 females artificially inseminated, the only one that was inseminated in the non-breeding season became pregnant and delivered a single cub. This is the first successful pregnancy resulting from AI in this endangered species.

To explore the association between endometriosis stage, characteristics of endometriotic lesions and severity of dysmenorrhoea. The clinical data were collected from 140 patients with laparoscopically diagnosed endometriosis between May 2013 and December 2013. They were scored by visual analogue scale (VAS) according to their preoperative dysmenorrhoea. Endometriotic lesions were recorded by their anatomical distributions. And endometriosis was staged and scored according to the score of Revised American Fertility Society (r-AFS). The relationship between dysmenorrhoea and endometriosis stage as well as endometriotic foci was analyzed. Chi-square test and Logistic regression were used for statistical analyses. Among them, there were 95 (67.86%) patients with dysmenorrhoea and 45(32.14%) without dysmenorrhoea. No significant inter-group difference existed in age (P > 0.05). The interval from menarche to the onset of dysmenorrhoea was (8 ± 9) years and duration of dysmenorrhoea (2.3 ± 1.5) days each month. A correlation existed between endometriosis stage and severity of dysmenorrhoea (χ² = 20.677, P < 0.05). A strong association was found between posterior cul-de-sac obliteration and severity of dysmenorrhoea (χ² = 8.471, P < 0.05). No significant difference was found for ovarian endometriomas, ovarian adhesion, superficial peritoneal lesions and deep infiltrating endometriosis in non- and minimal dysmenorrhoea groups with moderate and severe dysmenorrhoea (P > 0.05). Posterior cul-de-sac obliteration was an independent influencing factor for dysmenorrhoea. The odds ratio (OR) was 3.291 and 95% confidence interval (CI) 1.453-7.454. However, no relevance existed between ovarian endometriomas and dysmenorrhoea by Logistic analysis. The severity of dysmenorrhoea has close correlation with posterior cul-de-sac obliteration. However, there is a weak relevance with ovarian endometreaiomas.

Octogenarians with ovarian cancer limited to the abdomen may not be willing or able to undergo systemic chemotherapy. Low-dose pressurized intraperitoneal aerosol chemotherapy (PIPAC) with cisplatin and doxorubicin is a form of intra-abdominal chemotherapy which can be applied repeatedly and potentially prevents from the systemic side-effects of chemotherapy. We present the case of an 84-year-old woman with laparoscopically and histologically confirmed ovarian cancer who refused to undergo systemic chemotherapy. She was treated with eight courses q 28-104 days of low-dose PIPAC with cisplatin at 7.5 mg/m(2) and doxorubicin at 1.5 mg/m(2) at 12 mmHg and 37 °C for 30 min. Objective tumor response was noted, defined as tumor regression on histology, and stable disease noted by peritoneal carcinomatosis index on repeated video-laparoscopy and abdominal computed tomographic scan. The treatment was well-tolerated with no Common Terminology Criteria for Adverse Events (CTCAE) CTCAE >2. With a follow-up of 15 months, the patient is alive and clinically stable. The quality of life measured by the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 demonstrated improvement over 5-6 months (global physical score, global health score, global quality of live) without cumulative increase of gastrointestinal toxicity. Low-dose PIPAC is a new form of intraperitoneal chemotherapy which may be applied repeatedly in octogenarian patients. PIPAC may be an alternative and well-tolerated treatment for selected octogenarian patients with ovarian cancer limited to the abdomen who cannot be treated with systemic chemotherapy.

Risks of conservative management in women with ovarian endometriomas undergoing IVF.

2015-01-01

Classical surgical management of endometriotic ovarian cysts using the laparoscopic stripping technique has been recently questioned because of the surgical-related injury to the ovarian reserve. Accordingly, available guidelines suggest that endometriomas with a mean diameter below 4 cm should not be systematically removed before IVF procedures. However, conservative management may have some potential drawbacks and risks. The presence of the endometrioma may theoretically interfere with ovarian responsiveness to hyperstimulation and oocyte competence, the retrieval of the oocytes may be more difficult and risky, the disease may progress during the procedure, pregnancy outcome may be affected and there is the risk of missing occult malignancies with cancer development later in life. In the present review, we aimed at assessing whether these risks do exist and, if so, at estimating their clinical relevance. We searched PubMed for articles published in the English language between January 1990 and August 2014 that reported on endometriomas and assisted reproductive techniques. Special care was given to studies reporting data purporting to distinguish the effects of ovarian endometriomas per sé from those consequent to surgery for endometriosis or from endometriosis in general. Based on the evidence reviewed in the present study, it can be concluded that conservative management may actually expose women to four of the following theoretical risks, i.e. infection of the endometriomas, follicular fluid contamination with the endometrioma content, higher risk of pregnancy complications and cancer development later in life. The first three conditions do not justify surgery because these events are uncommon and the number of women needed to be treated would be exceedingly high and would not justify the costs and risks of the intervention. Albeit also very rare, the possibility of developing ovarian cancer later in life is more troublesome because it is a life-threatening condition. However, this alarmism is supported by only one cohort study and this risk can be effectively prevented by postponing surgery until after the IVF programme is concluded or when women have definitely satisfied their reproductive wishes. The available evidence on the risks of conservative management does not support systematic surgery before IVF in women with small ovarian endometriomas. © The Author 2015.

What does this document on the surgical treatment of endometriosis jointly prepared by the European Society for Gynaecological Endoscopy (ESGE), ESHRE, and the World Endometriosis Society (WES) provide? This document provides recommendations covering technical aspects of different methods of surgery for endometriomas in women of reproductive age. Endometriomas (ovarian endometriotic cysts) are a commonly diagnosed form of endometriosis, owing to the relative ease and accuracy of ultrasound diagnosis. They frequently present a clinical dilemma as to whether and how to treat them when found during imaging or incidentally during surgery. Previously published guidelines have provided recommendations based on the best available evidence, but without technical details on the management of endometriosis. A working group of ESGE, ESHRE and WES collaborated on writing recommendations on the practical aspects of endometrioma surgery. This document focused on endometrioma surgery. Further documents in this series will provide recommendations for surgery of deep and peritoneal endometriosis. The document presents general recommendations for surgery of endometrioma and specific recommendations for cystectomy, ablation by laser or by plasma energy, electrocoagulation and a combination of these techniques applied together or with an interval between them. Owing to the limited evidence available, recommendations are mostly based on clinical expertise. These recommendations complement previous guidelines on the management of endometriosis. The meetings of the working group were funded by ESGE, ESHRE and WES.

To develop a risk scoring system (RSS) for predicting recurrence in women with borderline ovarian tumours (BOTs). Cohort study of women with BOTs. French multicentre tertiary care centres. A cohort of 360 women with BOTs who received primary surgical treatment between January 2000 and December 2013. Clinical and pathological factors affecting recurrence in women with BOTs. The development of a model for the prediction of recurrence in women with BOTs. Overall the recurrence rate was 20.0% (72/360). Recurrence was associated with five variables: age < 45 years; preoperative serum tumour marker CA125 > 150 IU/mL; a serous histological subtype; International Federation of Gynecology and Obstetrics (FIGO) stage other than IA; and ovarian surgery other than bilateral salpingo-oophorectomy (BSO; i.e. cystectomy and unilateral salpingo-oophorectomy). These variables were included in the RSS and assigned scores ranging from 0 to 6. The discrimination of the RSS was 0.82 (95% confidence interval, 95% CI 0.79-0.85). A total score of 8 points corresponded to the optimal threshold of the RSS, with a rate of recurrence of 11.8% (35/297) and 58.7% (37/63) for women at low risk (<8 points) and women at high risk (≥8 points), respectively. The diagnostic accuracy was 85.0%. This study shows that the risk of BOT recurrence can be accurately predicted so that women at high risk can benefit from adapted surgical treatment. Our RSS permitted women with BOTs at low risk to be distinguished from women with BOTs at high risk of recurrence. © 2017 Royal College of Obstetricians and Gynaecologists.

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

PubMed Central

Wezel, Felix; Vallo, Stefan

2017-01-01

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

We examined whether the presence and severity of preoperative hydronephrosis have prognostic significance in patients who underwent radical cystectomy for transitional cell carcinoma of the bladder. The medical records of 457 patients who underwent radical cystectomy for bladder cancer between 1986 and 2005 were retrospectively reviewed. Following the Society for Fetal Urology grading system, patients were divided into low-, and high-grade hydronephrosis groups. Clinicopathologic factors associated with preoperative hydronephrosis and survival were evaluated. Of a total of 406 patients, unilateral hydronephrosis was found in 74 (18.2%), bilateral hydronephrosis in 11 (2.7%), and no hydronephoris in 321 (79.1%). Low-grade hydronephrosis was found in 57 (12.2%) patients and high-grade hydronephrosis in 28 (6%). Preoperative hydronephrosis was related to higher pT stage and lymph node invasion. In univariate analysis, the presence of hydronephrosis, hydronephrosis grade, age, pT and pN stage, tumor grade, surgical margin, number of retrieved nodes, carcinoma in situ, and lymphovascular invasion were significant prognostic factors for cancer-specific survival. In multivariate analysis, bilateral hydronephrosis and high-grade hydronephrosis remained significant predictors for decreased survival. The presence of preoperative hydronephrosis, and high-grade hydronephrosis are significant prognostic factors in patients with bladder cancer after radical cystectomy. PMID:20191034

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.

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

Ovulation induction in women with polycystic ovary syndrome.

2013-08-01

Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility. There are multiple ways to induce ovulation in PCOS patients, which will eventually provide a successful live birth. Each of these treatments varies in aggressiveness and effectiveness. Ranging from lifestyle modifications, through insulin-sensitizing agents, selective estrogen receptor modulators, aromatase inhibitors, gonadotropins, to laparoscopic ovarian drilling and assisted reproductive techniques, each method achieves ovulation induction through different mechanisms of action. This review provides a description and specific characteristics of the different methods used for ovulation induction which can help to design a personalized approach to each PCOS patient, and a general stepwise approach to ovulation induction in these patients.

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

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

Preliminary data on the effects of prophylactic bilateral salpingectomy (PBS) show that postoperative ovarian function is preserved up to 3 months after surgery. The confirmation of PBS safety on ovarian function even many years after surgery is essential to reassure the medical community that this new strategy, recently proposed for the prevention of ovarian cancer, is at least able to avoid the risk of premature surgical menopause. We investigated whether the addition of PBS during total laparoscopic hysterectomy (TLH) causes long-term effects on ovarian function. An observational study (Canadian Task Force classification II-3). Department of Obstetrics and Gynecology, "Magna Graecia" University, Catanzaro, Italy. Seventy-nine patients who underwent TLH plus salpingectomy between September 2010 and September 2012 at our institution have been recalled to be submitted to ovarian reserve evaluation in February 2015. Eight of 79 women refused to participate in this follow-up study. The ovarian age of PBS patients has been determined through OvAge (OvAge sr., Catanzaro, Italy), a statistical model that combines antimüllerian hormone, follicle-stimulating hormone, 3-dimensional antral follicle count, vascular index, flow index, and vascular flow index values. The control group consisted of a large population of 652 healthy women (with intact uterus and adnexa) previously enrolled to build the OvAge model. Comparisons between ovarian ages of PBS patients and the control group have been assessed by analysis of covariance linear statistical modeling. The main outcome measurement was the differences in the behavior within OvAge/age relation between PBS and control women. Descriptive statistics of those 71 enrolled PBS patients are the following: age, 49.61 ± 2.15 years; OvAge, 49.22 ± 2.57 years; follicle-stimulating hormone, 43.02 ± 19.92 mU/mL; antimüllerian hormone, 0.12 ± 0.20 ng/mL; 3-dimensional antral follicle count, 1.91 ± 1.28; vascular index, 2.80% ± 5.32%; flow index, 19.37 ± 5.88; and vascular flow index, 0.56 ± 1.12. Analysis of covariance disclosed that PBS and control women do not exhibit different behaviors (p = .900) within OvAge/age relation. According to our model, the addition of PBS to TLH in the late reproductive years does not modify the ovarian age of treated women up to 3 to 5 years after surgery. Copyright © 2016 AAGL.

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.

[Bladder neck sclerosis following prostate surgery : Which therapy when?

2017-09-01

Secondary bladder neck sclerosis represents one of the more frequent complications following endoscopic, open, and other forms of minimally invasive prostate surgery. Therapeutic decisions depend on the type of previous intervention (e.g., radical prostatectomy, TURP, HoLEP, radiotherapy, HIFU) and on associated complications (e.g., incontinence, fistula). Primary treatment in most cases represents an endoscopic bilateral incision. No specific advantages of any type of the applied energy (i.e., mono-/bipolar HF current, cold incision, holmium/thulium YAG laser) could be documented. Adjuvant measures such as injection of corticosteroids or mitomycin C have not been helpful in clinical routine. In case of first recurrence, a transurethral monopolar or bipolar resection can usually be performed. Recently, the ablation of the scared tissue using bipolar vaporization has been recommended providing slightly better long-term results. Thereafter, surgical reconstruction is strongly recommended using an open, laparoscopic, or robot-assisted approach. Depending on the extent of the bladder neck sclerosis and the underlying prostate surgery, a Y-V/T-plasty, urethral reanastomosis, or even a radical prostatectomy with new urethravesical anastomosis should be performed. Stent implantation should be reserved for patients who are not suitable for surgery. The final palliative measure is a cystectomy with urinary diversion or a (continent) cystostomy.

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.

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.

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.

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.

The objectives of this study are to evaluate if robotic cystectomy demonstrates reduced complications, readmissions, and cost-to-patient compared to open approach 30-day post-operatively, and to identify predictors of complication, readmission, and cost-to-patient. This retrospective cohort study analyzed 249 patients who underwent open (n = 149) or robotic (n = 100) cystectomy from 2009 to 2015 at our institution. Outcomes included 30-day post-operative complication, readmission, and cost-to-patient charges. We used modified Clavien-Dindo/MSKCC classifications. Multivariable logistic and linear regression models were used to evaluate associations to outcomes and to build predictive models. Patient, clinical, and surgical characteristics differed by open and robotic groups, respectively, only for estimated blood loss (median: 600 versus 150 cc, p < 0.01), operative time (mean: 6.19 versus 6.85 h, p < 0.01), and length of stay (median: 7 versus 5 days, p < 0.01). Complication: frequency of patients with at least one 30-day complication was 85% compared to 66% (p < 0.01). Minor gastrointestinal and bleeding complications were increased in the open group (50% versus 41%, p = 0.01; 52% versus 11%, p < 0.01, respectively). Fifty percent of patients required blood transfusion in open compared to 11% (p < 0.01). Patients in the open group experienced more major complications (19% versus 10%, p = 0.04). Robotic approach was a predictor for fewer complications (OR 0.44, 95% CI 0.20-0.99, p = 0.049). Readmission: no significant difference in number of patients readmitted was found. Cost-to-patient: Robotic approach predicted an 18% reduction in total cost-to-patient compared to open approach (p < 0.01). Robotic cystectomy demonstrated reduced total cost-to-patient when taking into account all 30-day post-operative services with fewer complications compared to open cystectomy.

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.

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.

To demonstrate the technique of laparoscopic double discoid resection with a circular stapler for bowel endometriosis. Case report (Canadian Task Force classification III). Private hospital in Curitiba, Paraná, Brazil. A 33-year-old woman was referred to our service complaining about cyclic dysmenorrhea, dyspareunia, chronic pelvic pain, and cyclic dyschezia. Transvaginal ultrasound with bowel preparation showed a 6-cm endometriotic nodule at the retrocervical area, uterosacral ligaments, posterior vaginal fornix, and anterior rectal wall, infiltrating up to the submucosa, 5 cm far from the anal verge. Under general anesthesia, the patient was placed in the dorsal decubitus position with her arms alongside her body and her lower limbs in abduction. Pneumoperitoneum was achieved using a Veres needle placed at the umbilicus. Four trocars were placed: a 10-mm trocar at the umbilicus for the zero-degree laparoscope; a 5-mm trocar at the right anterosuperior iliac spine; a 5-mm trocar in the midline between the umbilicus and the pubic symphysis, approximately 8 to 10 cm inferior to the umbilical trocar; and a 5-mm trocar at the left anterosuperior iliac spine. The entire pelvis was inspected for endometriotic lesions, and all implants in the anterior compartment of the pelvis were resected. The lesions located at the ovarian fossae were completely removed. The ureters were identified bilaterally, and both para-rectal fossae were dissected. The right hypogastric nerve was released from the disease laterally. The lesion was separated from the retrocervical area, and the posterior vaginal fornix was resected (reverse technique), leaving the disease attached to the anterior surface of the rectum. The lesion was shaved off the anterior rectal wall using a harmonic scalpel. A x-shaped stitch was placed at the anterior rectal wall using 2-0 mononylon suture. A 33-mm circular stapler was placed transanally under laparoscopic control, and once it reached the area to be resected, it was opened. A gap was created between the envil and the stapler. The anterior rectal wall was placed inside this gap with the aid of the stitch at the anterior rectal wall. The stapler was fired, and a piece of the anterior rectal wall was resected. The same procedure was performed using a 29-mm circular stapler, which allowed for the complete removal of the lesion. We usually perform the second discoid resection using a 29-mm circular stapler to allow an easy progression of the stapler through the rectum beyond the first stapler line, so not to put too much pressure on it. In our experience, the first discoid resection removes most of the disease, and the second discoid resection is only needed to remove a small amount of residual disease, along with the first staple line. The procedure took 177 min, and the estimated blood loss was 100 mL. The patient started clear liquids 6 hours after the procedure, and was discharged 19 hours after that [1]. Pathological examination of the 2 strips of the anterior rectal wall revealed infiltration of the bowel wall by endometriotic tissue. She had an uneventful postoperative course, and was able to re-start sexual intercourse 50 days after surgery. Between January 2010 and January 2015, 315 women underwent laparoscopic surgery for the treatment of bowel endometriosis in our service. Among them, 16 (5.1%) were operated on by using the double discoid resection technique. Median age of the patients was 34 years, and median body mass index was 25.9 kg/m(2). Median preoperative cancer antigen-125 level was 26.5 U/mL (normal value is <35 U/mL). Median size of the rectosigmoid nodule was 35 mm (range: 30-60), and median distance from the anal verge was 10.5 cm (range: 5-15 cm). Median surgical time was 160 min (range: 54-210 min). Concomitant procedures included hysterectyomy (n = 5), partial cystectomy (n = 3), resection of the posterior vaginal fornix (n = 4), and appendectomy (n = 1). Median estimated intraoperative bleeding was 32.5 mL (range: 30-100), and median time of hospitalization was 19 hours (range: 10-41). Median American Fertility Society score was 46 (10-102). Two minor complications (12.5%) occurred in this initial series: 1 patient required bladder catheterization for urinary retention; and 1 patient developed a urinary tract infection that required oral antibiotic treatment. One major complication (6.2%) was observed; the patient developed fever and abdominal pain on the fourth postoperative day. She was re-operated, and the intraoperative diagnosis was pelviperitonitis. The abdominal cavity was inspected for any dehiscence of the bowel and then washed. She was discharged on the second day after re-operation with oral antibiotic therapy. In our daily practice, we are used to discharging our patients soon in the postoperative setting (19 hours for rectal shaving or discoid resection and 28 hours for segmental bowel resection) [1] because the rate of postoperative fistula seems to be low [2]. Because we still have not seen any fistulas after conservative surgery (rectal shaving, discoid resection, and double discoid resection), we usually prefer to perform this type of surgery compared with segmental bowel resection, when possible. Laparoscopic double discoid resection with circular stapler may be an alternative to segmental bowel resection in selected patients with bowel endometriosis. Copyright © 2015 AAGL.

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.

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.

Polycystic ovary syndrome (PCOS) is the most common cause of infrequent periods (oligomenorrhoea) and absence of periods (amenorrhoea). It affects about 4% to 8% of women worldwide and often leads to anovulatory subfertility. Aromatase inhibitors (AIs) are a novel class of drugs that were introduced for ovulation induction in 2001. Over the last ten years clinical trials have reached differing conclusions as to whether the AI letrozole is at least as effective as the first-line treatment clomiphene citrate (CC). To evaluate the effectiveness and safety of aromatase inhibitors for subfertile women with anovulatory PCOS. We searched the following sources from inception to 24/10/2013 to identify relevant randomised controlled trials (RCTs): the Menstrual Disorders and Subfertility Group Specialised Register, the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, PsycINFO, Pubmed, LILACS, Web of Knowledge, the World Health Organisation (WHO) clinical trials register and Clinicaltrials.gov. Furthermore, we manually searched the references of relevant articles.The search was not restricted by language or publication status. We included all RCTs of aromatase inhibitors used alone or with other medical therapies for ovulation induction in women of reproductive age with anovulatory PCOS. Two review authors independently selected trials, extracted the data and assessed trial quality. Studies were pooled where appropriate using a fixed effect model to calculate pooled odds ratios (ORs) and 95% confidence intervals (CIs) for most outcomes and risk differences (RDs) for ovarian hyperstimulation syndrome (OHSS). The primary outcomes were live birth and OHSS. Secondary outcomes were pregnancy, miscarriage and multiple pregnancy. The quality of the evidence for each comparison was assessed using GRADE methods. We included 26 RCTs (5560 women). In all studies the aromatase inhibitor was letrozole. Live birth (12 RCTs) One RCT compared letrozole with placebo in women who were clomiphene resistant and the results were inconclusive (OR 3.17, 95% CI 0.12 to 83.17, n=36)Nine RCTs compared letrozole with clomiphene citrate (with or without adjuncts) followed by timed intercourse. The birth rate was higher in the letrozole group (OR 1.63, 95% CI 1.31 to 2.03, n=1783, I²=3%)Two RCTs compared letrozole with laparoscopic ovarian drilling. There was no evidence of a difference between the groups in live birth rate (OR 1.19, 95% CI 0.76 to 1.86, n=407, I²=0%) OHSS (16 RCTs) There was no evidence of a difference in OHSS rates when letrozole was compared with placebo (one RCT, n=36), clomiphene citrate (with or without adjuncts) followed by timed intercourse (nine RCTs, n=2179), clomiphene citrate (with or without adjuncts) followed by intrauterine insemination (IUI) (two RCTs, n=1494), laparoscopic ovarian drilling (one RCT, n=260) or anastrozole (one RCT, n=220). Events were absent or very rare, and no study had more than 2 cases of OHSS. Clinical pregnancy (25 RCTs) One RCT compared letrozole versus placebo in women who were clomiphene resistant and the results were inconclusive (OR 3.17, 95% CI 0.12 to 83.17, n=36)Fourteen RCTs compared letrozole versus clomiphene citrate (with or without adjuncts) followed by timed intercourse. The pregnancy rate was higher in the letrozole group (OR 1.32, 95% CI 1.09 to 1.60, n=2066, I²=25%)Three RCTs compared letrozole versus clomiphene citrate (with or without adjuncts) followed by IUI. The pregnancy rate was higher in the letrozole group (OR 1.71, 95% CI 1.30 to 2.25, n=1597)Three RCTs compared letrozole versus laparoscopic ovarian drilling. There was no evidence of a difference in the clinical pregnancy rate (OR 1.14, 95% CI 0.80 to 1.65, n=553, I²=0%)Two RCTs compared letrozole versus anastrozole, one RCT compared a five day versus a 10 day administration protocol for letrozole and another RCT compared 5 mg of letrozole versus 7.5 mg of letrozole. There was no evidence of a difference in the clinical pregnancy rate in these comparisons.The quality of the evidence was rated as low for live birth and pregnancy outcomes. The reasons for downgrading the evidence were poor reporting of study methods, possible publication bias and the tendency for studies that reported live birth to report higher clinical pregnancy rates in the letrozole group than studies that failed to report live birth (suggesting that results might be somewhat less favourable to letrozole if all studies reported live birth). Letrozole appears to improve live birth and pregnancy rates in subfertile women with anovulatory PCOS, compared to clomiphene citrate. The quality of this evidence is low and findings should be regarded with some caution. There appears to be no difference in effectiveness between letrozole and laparoscopic ovarian drilling, though there were few relevant studies. OHSS was a very rare event, with no occurrences in most studies.

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.

In 2013, 10 topics were selected for major clinical research advances in gynecologic oncology; these included three topics regarding cervical cancer, three regarding ovarian cancer, two regarding endometrial cancer, and one each regarding breast cancer and radiation oncology. For cervical cancer, bevacizumab was first demonstrated to exhibit outstanding clinical efficacy in a recurrent, metastatic setting. Regarding cervical cancer screening, visual inspections with acetic acid in low-resource settings, p16/Ki-67 double staining, and the follow-up results of four randomized controlled trials of human papillomavirus-based screening methods were reviewed. Laparoscopic para-aortic lymphadenectomy before chemoradiation for locally advanced cervical cancer was the final topic for cervical cancer. Regarding front-line ovarian cancer therapies, dose-dense paclitaxel and carboplatin, intraperitoneal chemotherapy, and other targeted agents administered according to combination or maintenance schedules were discussed. Regarding recurrent ovarian cancer treatment, cediranib, olaparib, and farletuzumab were discussed for platinum-sensitive disease. The final overall survival data associated with a combination of bevacizumab and chemotherapy for platinum-resistant disease were briefly summarized. For endometrial cancer, the potential clinical efficacy of metformin, an antidiabetic drug, in obese patients was followed by integrated genomic analyses from the Cancer Genome Atlas Research Network. For breast cancer, three remarkable advances were reviewed: the long-term effects of continued adjuvant tamoxifen for 10 years, the effects of 2-year versus 1-year adjuvant trastuzumab for human epidermal growth factor receptor 2-positive disease, and the approval of pertuzumab in a neoadjuvant setting with a pathologic complete response as the surrogate endpoint. Finally, the recent large studies of intensity-modulated radiotherapy for gynecologic cancer were briefly summarized.

To introduce a new technique that combines laparoscopic and vaginal cervicovaginal reconstruction using split thickness skin graft in patients with congenital atresia of the cervix. Video article introducing a new surgical technique. University hospital. A 16-year-old patient with congenital cervical atresia, vaginal dysgenesis, and ovarian endometrial cyst. An original technique of combined laparoscopic and vaginal cervicovaginal reconstruction using split thickness skin graft for cervicovaginal reconstruction. A midline incision at the vaginal introitus was made, and a 9-cm canal was made between the bladder and the rectum using sharp and blunt dissection along the anatomic vaginal route, with the aid of laparoscopy to ensure correct orientation. A 14 × 12 cm split thickness skin graft was harvested from the right lateral thigh. By laparoscopy, the level of the lowest pole of the uterine cavity was exposed and the cervix was incised by shape dissection. The proximal segment of the harvested skin to the lower uterine segment was secured, and the distal segment was sutured with the upper margin of vulva vaginally. Surgical technique reports in anonymous patients are exempted from ethical approval by the Institutional Review Board. The patient gave consent to use the video in the article. The procedure was successfully completed. Since February 2013, our experiences of combined laparoscopic and vaginal cervicovaginal reconstruction using split thickness skin graft in 10 patients with congenital atresia of cervix were positive, with successful results and without complications or cervical, or vaginal stenosis. Our technique is feasible and safe for congenital atresia of cervix, with successful results and without complications or cervical or vaginal stenosis.

Struma ovarii is an uncommon type of ovarian tumor derived by germinal cells, characterized by the predominance of thyroid tissue (> 50%); 90-95% of these formations are benign and mainly affect the left ovary, while in 6% of the cases struma ovarii is bilateral. The malignant transformation is a rare condition that often occurs after 50 years. In most instances, diagnosis of malignant struma ovarii is made postoperatively during histological analysis. This tumor appears to derive by one germinal cell through loss of heterozygosity of the androgen receptor gene and of the X chromosome. Clinical symptoms comprise abdominopelvic mass, lower abdominal pain, abnormal vaginal bleeding, and ascites (the occurrence of this condition has been observed in one-third of the cases). The patients with struma ovarii generally do not manifest symptoms related to thyroid hyperfunction, reported only in 8% of the cases, and due to hyperstimulation of the thyroid by auto-antibodies. Thyroid tissue of the struma ovarii, often embedded in a teratoma, may be papillary, follicular or with mixed pattern and it can include elements of mucinous cystoadenomas, Brenner's tumor or carcinoid or melanomas cells. Here the authors report their experience with an unusual case of Hashimoto thyroiditis onset after laparoscopic removal of struma ovarii.

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.

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

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.

[Urinary tract involvement by endometriosis. Techniques and outcomes of surgical management: CNGOF-HAS Endometriosis Guidelines].

Urinary tract involvement by endometriosis is reported in 1% of endometriosis patients (NP3). Consequences range from pelvic pain for bladder localizations to silent kidney loss in case of chronic ureteral obstruction (NP3). The feasibility of laparoscopic management was widely proven (NP3) and may reduce hospital stay length (NP4). Radical surgery with partial cystectomy for bladder localizations was shown to significantly and durably reduce pain symptoms with low risk of a severe postoperative complications (NP3). Medical hormonal treatment also shows short-term reduction of pain symptoms (NP4). Transureteral resection of bladder endometriosis nodule is not recommended (grade C) because of a high postoperative recurrence rate (NP4). Given a high risk of silent kidney loss, it is recommended that patients with ureteral involvement by endometriosis are managed by a multidisciplinary team considering urinary and potential extra-urinary localizations of endometriosis (grade C). No recommendation can be made on which technique to prefer between conservative (ureterolysis) or radical surgical techniques or on benefit and length of ureteral stents in case of ureteral involvement. Surgical management of bladder and ureteral localizations of endometriosis do not seem to be associated with altered or improved postoperative fertility (NP4). Since late postoperative ureteral anastomosis stenosis were reported with silent kidney loss, repeated postoperative imaging monitoring is justified (expert opinion).

The aim of this report is to describe our surgical technique of totally intracorporeal robotic assisted radical cystectomy (RARC) with neobladder formation. Between December 2003 and March 2013, a total of 147 patients (118 male, 29 female) underwent totally intracorporeal RARC for urinary bladder cancer. We also performed a systematic search of Medline, Embase and PubMed databases using the terms RARC, robotic cystectomy, robot-assisted, totally intracorporeal RARC, intracorporeal neobladder, intracorporeal urinary diversion, oncological outcomes, functional outcomes, and complication rates. The mean age of our patients was 64 years (range 37-87). On surgical pathology 47% had pT1 or less disease, 27% had pT2, 16% had pT3 and 10% had pT4. The mean number of lymph nodes removed was 21 (range 0-60). 24% of patients had lymph node positive dAQ1isease. Positive surgical margins occurred in 6 cases (4%). Mean follow-up was 31 months (range 4-115 months). Two patients (1.4%) died within 90 days of their operation. Using Kaplan-Meier analysis, overall survival and cancer specific survival at 60 months was 68% and 69.6%, respectively. 80 patients (54%) received a continent diversion with totally intracorporeal neobladder formation. In the neobladder subgroup median total operating time was 420 minutes (range 265-760). Daytime continence and satisfactory sexual function or potency at 12 months ranged between 70-90% in both men and women. Our experience with totally intracorporeal RARC demonstrates acceptable oncological and functional outcomes that suggest this is a viable alternative to open radical cystectomy.

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.

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.

To compare the intraoperative direct costs of a single-use energy device with reusable energy devices during laparoscopic hysterectomy. A randomized controlled trial (Canadian Task Force Classification I). An academic hospital. Forty-six women who underwent laparoscopic hysterectomy from March 2013 to September 2013. Each patient served as her own control. One side of the uterine attachments was desiccated and transected with the single-use device (Ligasure 5-mm Blunt Tip LF1537 with the Force Triad generator). The other side was desiccated and transected with reusable bipolar forceps (RoBi 5 mm), and transected with monopolar scissors using the same Covidien Force Triad generator. The instrument approach used was randomized to the attending physician who was always on the patient's left side. Resident physicians always operated on the patient's right side and used the converse instruments of the attending physician. Start time was recorded at the utero-ovarian pedicle and end time was recorded after transection of the uterine artery on the same side. Costs included the single-use device; amortized costs of the generator, reusable instruments, and cords; cleaning and packaging of reusable instruments; and disposal of the single-use device. Operating room time was $94.14/min. We estimated that our single use-device cost $630.14 and had a total time savings of 6.7 min per case, or 3.35 min per side, which could justify the expense of the device. The single-use energy device had significant median time savings (-4.7 min per side, p < .001) and total intraoperative direct cost savings ($254.16 per case). A single-use energy device that both desiccates and cuts significantly reduced operating room time to justify its own cost, and it also reduced total intraoperative direct costs during laparoscopic hysterectomy in our institution. Operating room cost per minute varies between institutions and must be considered before generalizing our results. Copyright © 2016 AAGL. Published by Elsevier Inc. All rights reserved.

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.

Abstract 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. PMID:29095253

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.

Endometriosis is a benign pathology that affects 3% of the general population and about 10% of women of reproductive age. Three anatomoclinical entities are described: peritoneal, ovarian (endometrioma) and deep endometriosis characterized by the infiltration of anatomical structures or organs beyond the peritoneum. Laparoscopic surgery should be performed, as this is associated with a reduction in postoperative complications, length of hospitalization and convalescence. Several surgical techniques allow the removal of deep endometriosis with colorectal involvement: rectal shaving, anterior discoid resection, segmental resection. Deep endometriosis surgery with colorectal involvement is a source of postoperative complications: anastomotic fistula, rectovaginal fistula, intestinal occlusion, digestive haemorrhage, urinary fistula, deep pelvic abscess. Involvement of the urinary tract by endometriosis affects approximately 1% of patients with endometriosis. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Endometriosis-related ascites is rare and is frequently confused with an ovarian malignancy. Since it affects women in reproductive age, its diagnosis and therapy are even more challenging. These patients usually present with abdominal distension, pelvic pain, and weight loss, but a careful questioning usually reveals the typical endometriosis symptoms-such as dysmenorrhea and dyspareunia. We present three cases of endometriosis-related ascites, one of them with pleural effusion. All cases were associated with extensive disease and required laborious laparoscopic surgery, medical therapy with gonadotropin releasing hormone analogs, and long-term follow-up. One of the patients delivered twins following an in vitro fertilization (IVF) cycle without recurrence of ascites. We aim to raise awareness toward the importance of considering endometriosis in a patient with ascites of unknown origin.

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.

Which is the best method for human ovarian tissue cryopreservation: slow freezing/rapid thawing (SF/RT) or vitrification/warming (V/W)? The conventional SF/RT protocol used in this study seems to better preserve the morpho-functional status of human cryopreserved ovarian tissue than the used open carrier V/W protocol. Cryopreservation of human ovarian tissue is generally performed using the SF/RT method. However, reduction in the follicular pool and stroma damage are often observed. An emerging alternative procedure is represented by V/W which seems to allow the maintenance of the morphological integrity of the stroma. This is a retrospective cohort study including six patients affected by oncological diseases and enrolled from January to December 2014. Ovarian tissue was laparoscopically harvested from the right and left ovaries and was cryopreserved using a routinary SF/RT protocol or a V/W method, involving tissue incubation in two solutions (containing propylene glycol, ethylene glycol and sucrose at different concentrations) and vitrification in an open system. For each patient, three pieces from each ovary were collected at the time of laparoscopy (fresh tissue) and after storage (SF/RT or V/W) and processed for light microscopy (LM) and transmission electron microscopy (TEM), to assess the morphological and ultrastructural features of follicles and stroma, and for laser scanning confocal microscopy (LSCM), to determine the functional energetic/redox stroma status. The preservation status of SF/RT and V/W ovarian tissues was compared with that of fresh ones, as well as between them. By LM and TEM, SF/RT and V/W samples showed cryodamage of small entity. Interstitial oedema and increased stromal cell vacuolization and chromatin clumping were observed in SF/RT samples; in contrast, V/W samples showed oocyte nuclei with slightly thickened chromatin and irregular shapes. The functional imaging analysis by LSCM revealed that the mitochondrial activity and intracellular reactive oxygen species levels were reduced both in SF/RT and in V/W samples compared with fresh samples. The study also showed progressive dysfunction of the mitochondrial activity going from the outer to the inner serial section of the ovarian cortex. The reduction of mitochondrial activity of V/W samples compared with fresh samples was significantly higher in the inner section than in the outer section. The results report the bioenergetic and oxidative status assessment of fresh and cryopreserved human ovarian tissue by LSCM, a technique recently applied to tissue samples. The use of LSCM on human ovarian tissues after SF/RT or V/W is a new application that requires validation. The procedures for mitochondrial staining with functional probes and fixing are not yet standardized. Xenografting of the cryopreserved ovarian tissue in severe combined immunodeficient mice and in vitro culture have not yet been performed. The identification of a cryopreservation method able to maintain the morpho-functional integrity of the ovarian tissue and a number of follicles comparable with those observed in fresh tissue might optimize results in clinical practice, in terms of recovery, duration of ovarian function and increased delivery outcomes after replanting. The SF/RT protocol allowed better morpho-functional tissue integrity than the V/W procedure. Funding was provided by Fondazione del Monte di Bologna e Ravenna, Italy.

Isolated torsion of the fallopian tube without an ovarian abnormality is an uncommon event, with an incidence of approximately 1 in 1,500,000 females. Isolated torsion of the fallopian tube occurs mostly in reproductive-aged women, and is thus extremely rare in menopausal women and pre-pubertal girls. In case 1, 63-year-old Japanese woman presented with a 2-day history of acute lower abdominal pain. Menopause occurred at 53 years of age. Pelvic ultrasonography showed an enlarged mass (73 × 47 mm) on the right side of her uterus. An urgent laparoscopy was performed based on a presumptive diagnosis of right ovarian tumor torsion. During the laparoscopy, we noted a black, necrotic, solid tumor arising from the distal end of her right fimbria. Her right fallopian tube was twisted with the tumor, but her right ovary was normal and not involved. A laparoscopic tumorectomy with a right salpingectomy was performed. Her post-operative course was uneventful. In case 2, a 10-year-old Japanese girl presented with a 1-day history of lower abdominal pain associated with nausea and vomiting. Menarche had occurred 2 months earlier. A computed tomography and magnetic resonance imaging examination demonstrated a dilated tubal cystic mass with a normal uterus and bilateral ovaries. An urgent laparoscopy was performed based on a presumptive diagnosis of right fallopian tube torsion. During laparoscopy, her right fallopian tube was noted to be dark red, dilated, and twisted several times. Her right fimbria was necrotic-appearing and could not be preserved. Therefore, a laparoscopic right salpingectomy was performed. A histologic examination revealed ischemic changes with congestion of her right fallopian tube, which was consistent with tubal torsion. She had an uncomplicated post-operative course. We have presented two very rare cases of isolated fallopian tubal torsion. Radiologic interventions, such as computed tomography and magnetic resonance imaging, in addition to ultrasonography, are helpful diagnostic tools. Isolated torsion of the fallopian tube should be considered in the differential diagnosis of lower abdominal pain with a cystic mass and a normal ipsilateral ovary in all female patients, regardless of age.

Our objective was to compare the effectiveness of metformin plus clomiphene citrate vs. gonadotrophins, laparoscopic ovarian diathermy, aromatase inhibitors, N-acetyl-cysteine and other insulin sensitizers+clomiphene for improving fertility outcomes in women with clomiphene-resistant polycystic ovary syndrome. PubMed, SCOPUS and CENTRAL databases were searched until April 2014 with the key words: PCOS, polycystic ovary syndrome, metformin, clomiphene citrate, ovulation induction and pregnancy. The search was limited to articles conducted with humans and published in English. The PRISMA statement was followed. Twelve randomized controlled trials (n = 1411 women) were included. Ovulation and clinical pregnancy rates per woman randomized. Compared with gonadotrophins, the metformin+clomiphene combination resulted in significantly fewer ovulations (odds ratio 0.25; 95% confidence interval 0.15-0.41; p < 0.00001, 3 trials, I(2) = 85%, n = 323) and pregnancies (odds ratio 0.45; 95% confidence interval 0.27-0.75; p = 0.002, 3 trials, I(2) = 0%, n = 323). No significant differences were found when metformin+clomiphene was compared with laparoscopic ovarian diathermy (odds ratio 0.88; 95% confidence interval 0.53-1.47; p = 0.62, 1 trial, n = 282; odds ratio 0.96; 95% confidence interval 0.60-1.54; p = 0.88, 2 trials, I(2) = 0%, n = 332, for ovulation and pregnancy rates, respectively). Likewise, no differences were observed in comparison with aromatase inhibitors (odds ratio 0.88; 95% confidence interval 0.58-1.34; p = 0.55, 3 trials, I(2) = 3%, n = 409; odds ratio 0.85; 95% confidence interval 0.53-1.36; p = 0.50, 2 trials, n = 309, for ovulation and pregnancy rates, respectively). There is evidence for the superiority of gonadotrophins, but the metformin+clomiphene combination is mainly relevant for clomiphene-resistant polycystic ovary syndrome patients and, if not effective, a next step could be gonadotrophins. More attempts with metformin+clomiphene are only relevant if there is limited access to gonadotrophins. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

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

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

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.

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.  .

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.

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.

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.

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

To present a case of a vital ectopic pregnancy after 8 weeks that was located in the right ovary. Case study and literature review. Hospital outpatient clinic. A 29-year-old primigravida presented with lower abdominal pain and mild vaginal bleeding at 8 weeks after her last menstrual period. Wedge resection of the ovary which did not affect subsequent fertility. Conservative treatment options and preservation of patient's reproductive capacity. The embryo was laparoscopically removed in toto and visualized. Therefore, macroscopic correlation to Carnegie stage 16 of development was possible. Approximately 3% of all ectopic pregnancies are located in the ovaries. Preoperative diagnosis of this extremely rare condition is challenging, because the ectopic tumor often resembles cysts of the corpus luteum. At surgery, the trophoblast tissue or the embryo can rarely be visualized completely.

Tuberculosis is still a common problem in immigrant population with peritoneal tuberculosis as the most common presentation of extrapulmonary disease. A 36-year-old woman presented with abdominal distention, night sweats and weight loss. Physical examination and radiologic studies revealed ascites, omental caking and bilateral enlarged ovaries with an elevated serum Ca-125 of 353 U/mL. Acid-fast stain and culture were negative for Mycobacterium tuberculosis. Diagnostic laparoscopy and biopsy revealed multiple granulomas with epithelioid cells and caseification necrosis confirming tuberculosis. Treatment with anti-tuberculin drugs resulted in resolution of symptoms with a reduction in Ca-125 to normal. Laparoscopic biopsy with frozen section evaluation would spare patients with peritoneal tuberculosis from unnecessary extensive surgery. Serum Ca-125 level may be useful in monitoring treatment response.

The study deals with the preoperative ultrasound diagnosis of ovarian endometriosis, postoperative ultrasound reassessment, laparoscopic surgical resolution of ovarian endometriosis, estimation of recurrence risk 12 months after surgery by ultrasound, reappearance of clinical symptoms (such as pain) or second-look laparoscopy, and pregnancy rate 2 years after surgery. 140 patients with en- dometriosis and infertility admitted to the Iasi "Cuza-Vodă" Clinical Hospital of Obstetrics and Gynecology between the years 2009-2011 were included in the study. The patients were divided into 2 groups: group 1-59 cases that refused in vitro fertilization procedures, did not afford in vitro fertilization (IVF) or had minimal endometriosis and young ages and thus a possibility of delaying treatment, and group 2--62 cases which underwent IVF procedures immediately after surgery. No significant differences in the chance of becoming pregnant were found between the two groups (χ2 = 2.06, p = 0.0891, 95% CI); in group 1, 11.86% pregnancies were obtained while in group 2 the pregnancy rate was 11.29%. Based on the nonparametric method of analysis of contingency tables we could estimate the odds of becoming pregnant in the study groups, obtaining an odds ratio (OR = 1.16, CI: 1.04-2.23, 95% CI). This result indicated that in group 1 the odds of becoming pregnant was not significantly higher, and the estimation was made for a confidence interval of 95%. The study had in view the assessment of pregnancies obtained in the study groups and the time interval (number of weeks) from the time of intervention until the occurrence of pregnancy. The Kaplan-Meier analysis enabled the assessment of the mean value and the median value of the number of weeks until becoming pregnant, and these values did not show significant differences (χ2 = 1.55, p = 0.212, 95% CI). For endometriosis associated with infertility, hormonal suppression does not improve fertility, and therefore surgery followed by controlled ovarian hyperstimulation and intrauterine insemi- nation (IUI), provided the anatomy of the pelvis is preserved in early cases or in vitro fertilization in severe cases is preferred.

Abstract. In comparison to open surgery, endoscopic surgery offers impaired depth perception and narrower field-of-view. To improve depth perception, the Da Vinci robot offers three-dimensional (3-D) video on the console for the surgeon but not for assistants, although both must collaborate. We improved the shared perception of the whole surgical team by connecting live 3-D monitors to all three available Da Vinci generations, probed user experience after two years by questionnaire, and compared time measurements of a predefined complex interaction task performed with a 3-D monitor versus two-dimensional. Additionally, we investigated whether the complex mental task of reconstructing a 3-D overview from an endoscopic video can be performed by a computer and shared among users. During the study, 925 robot-assisted laparoscopic procedures were performed in three hospitals, including prostatectomies, cystectomies, and nephrectomies. Thirty-one users participated in our questionnaire. Eighty-four percent preferred 3-D monitors and 100% reported spatial-perception improvement. All participating urologists indicated quicker performance of tasks requiring delicate collaboration (e.g., clip placement) when assistants used 3-D monitors. Eighteen users participated in a timing experiment during a delicate cooperation task in vitro. Teamwork was significantly (40%) faster with the 3-D monitor. Computer-generated 3-D reconstructions from recordings offered very wide interactive panoramas with educational value, although the present embodiment is vulnerable to movement artifacts.

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…

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.

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.

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.

Risk factors for upper tract recurrence following radical cystectomy for transitional cell carcinoma of the bladder are not yet well-defined. We reviewed our population of patients who underwent radical cystectomy to identify prognostic factors and clinical outcomes associated with upper tract recurrence. From our prospective database of 1,359 patients who underwent radical cystectomy we identified 1,069 patients treated for transitional cell carcinoma of the bladder between January 1985 and December 2001. Univariate analysis was completed to determine factors predictive of upper tract recurrence. A total of 853 men and 216 women were followed for a median of 10.3 years (maximum 18.5). There were 27 (2.5%) upper tract recurrences diagnosed at a median of 3.3 years (range 0.4 to 9.3). Only urethral tumor involvement was predictive of upper tract recurrence. In men superficial transitional cell carcinoma of the prostatic urethra was associated with an increased risk of upper tract recurrence compared with prostatic stromal invasion or absence of prostatic transitional cell carcinoma (p <0.01). In women urethral transitional cell carcinoma was associated with an increased risk of upper tract recurrence (p = 0.01). Despite routine surveillance 78% of upper tract recurrence was detected after development of symptoms. Median survival following upper tract recurrence was 1.7 years (range 0.2 to 8.8). Detection of asymptomatic upper tract recurrence via surveillance did not predict lower nephroureterectomy tumor stage, absence of lymph node metastases or improved survival. Patients with bladder cancer are at lifelong risk for late oncological recurrence in the upper tract urothelium. Patients with evidence of tumor involvement within the urethra are at highest risk. Surveillance regimens frequently fail to detect tumors before symptoms develop. However, radical nephroureterectomy can provide prolonged survival.

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.

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

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

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.

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

Ovulation induction in normogonadotropic anovulation (PCOS).

PubMed

van Santbrink, Evert J P; Fauser, Bart C J M

2006-06-01

Treatment of normogonadotropic anovulatory infertility (World Health Organization class 2, or WHO2) is by induction of ovulation using clomiphene citrate (CC), followed by follicle-stimulating hormone (FSH) in cases of treatment failure. Not all patients will become ovulatory or will conceive with this treatment. Others, exhibiting multifollicular instead of monofollicular development, may encounter complications such as ovarian hyperstimulation and multiple pregnancy. Recently introduced alternative treatment interventions-such as insulin-sensitizing drugs, aromatase inhibitors, or laparoscopic electrocautery of the ovaries-may offer the possibility of improving the efficacy of the classical ovulation induction algorithm. Based on initial patient characteristics, it may be possible to identify specific patient subgroups with altered chances of success or complications while using one of these interventions. Regarding CC and FSH ovulation induction, this has been performed using multivariate prediction models. This approach may enable us to improve safety, cost-effectiveness, and patient convenience in future ovulation induction.

Ovulation induction: a mini review.

PubMed

Messinis, Ioannis E

2005-10-01

Ovulation induction is the method for treating anovulatory infertility. For patients with hypogonadotrophic hypogonadism, the treatment involves administration of both FSH and LH, while HCG is injected for follicle rupture. Pulsatile GnRH has the same effectiveness as gonadotrophins and the advantage of the low multiple pregnancy rate. In polycystic ovary syndrome (PCOS), the first treatment choice is clomiphene citrate. With this drug, in properly selected patients, the cumulative pregnancy rate approaches that of normal women. Low-dose protocols of FSH are the second line of treatment, effective in inducing monofollicular development. Laparoscopic ovarian drilling can be an alternative but not as a first choice treatment in clomiphene-resistant patients. Other treatments, such as pulsatile GnRH and GnRH agonists, are hardly used today in PCOS. However, in obese women with PCOS, weight loss and exercise should be recommended as the first line of therapy. Newer agents including aromatase inhibitors and insulin sensitizers, although promising, need further evaluation.

Umbilical endometriosis has an estimated incidence of 0.5%-1% of all patients with endometrial ectopia. It is a very rare disease, but should be considered on the differential diagnosis of umbilical lesions. We report on a case of spontaneous umbilical endometriosis in a 38-year-old woman, with a dark brown nodule periodically bleeding, associated with severe abdominal pain. There was no history of endometriosis and she had not been pregnant before. Laparoscopic visualization of pelvic cavity showed bilateral ovarian endometrioma (it was removed while sparing the ovaries). Surgical treatment proved effective. Cutaneous endometriosis could be a sign of internal endometriosis. Presentations may be atypical and pose diagnostic difficulty, mimicking other acute diseases, e.g., skin neoplasm, folliculitis, etc., but it should be suspected in any female presenting with a painful or bleeding mass close to the umbilicus or abdominal surgical scar.

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

Robot-sewn ileoileal anastomosis during robot-assisted cystectomy.

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.

To investigate the clinical presentation, operative outcome, and incidence of malignancy in postmenopausal women who were diagnosed with adnexal torsion. Retrospective cohort study (Canadian Task Force classification II-2). Tertiary university-affiliated hospital. Postmenopausal women diagnosed with adnexal torsion between 1995 and 2014 (study group) were reviewed and compared with 220 premenopausal patients diagnosed with adnexal torsion during the same time period. Demographic data, clinical signs and symptoms, and intra- and postoperative characteristics were compared between the 2 groups. During the study period 44 postmenopausal women were diagnosed with adnexal torsion. Continuous dull pain was the most common presenting symptom in the postmenopausal group (57%), whereas acute-onset sharp pain was the predominant symptom in the premenopausal group (86%). The time interval from admission to surgery was significantly longer in the postmenopausal group (24 vs 6 hours, p < .001). Laparoscopic surgery was performed in 84.5% of the cases in the premenopausal group, whereas it was carried out in only 50% of cases in the postmenopausal group (p < .001). Four women in the postmenopausal group were diagnosed with malignancy, whereas only 1 case of malignancy was found in the premenopausal group (9% vs .4%, respectively; p = .003). Adnexal torsion in postmenopausal women is an uncommon event with a unique presentation. Because ovarian malignancy is not an uncommon finding in this group of patients, preparation for more extensive surgery should be contemplated. Copyright © 2016 AAGL. Published by Elsevier Inc.

The aim of the study was to evaluate the rate of relapse as well as disease-free, overall, and disease-specific survival in women with borderline ovarian tumour (BOT). Furthermore, the study aims to identify the clinical parameters correlated to relapse. National clinical data of women diagnosed with BOT from January 2005 to January 2013 constituted the basis for our study population. The prognostic influence of clinical variables was evaluated using univariate and multivariate analyses. A total of 1143 women were eligible for analysis, with 87.9% in FIGO stage I and 12.1% in FIGO stages II-IV. Relapse of BOT was detected in 3.7%, hereof 40.5% with malignant transformation. The five-year disease-free survival was 97.6% in FIGO stage I and 87.3% in FIGO stages II-IV. Younger age, laparoscopic surgical approach, fertility sparing surgery, FIGO stages II-IV, bilateral tumour presence, serous histology, implants and microinvasion of the tumour were significantly associated with relapse in univariate analyses. The overall five-year survival rate was 92.2% in FIGO stage I and 89.0% in FIGO stages II-IV. Out of 77 deaths in total, only seven women died from BOT. A general favourable prognosis in women with BOT was confirmed in our study. Our findings indicate that systematic, long-term follow-up does not seem necessary in women treated for FIGO stage IA BOT with no residual disease or microinvasion. Copyright © 2016 Elsevier Inc.

[Comparison of fertiloscopy versus laparoscopy in the exploration of the infertility: analysis of the literature].

Braidy, C; Nazac, A; Legendre, G; Capmas, P; Fernandez, H

2014-09-01

Fertiloscopy is a recent technique designed to explore the tubo-ovarian axis in unexplained infertility. It is a simple outpatient technique, allowing to perform operative procedures, but its position relative to laparoscopy is yet to be defined. A thorough and extensive bibliographical search was undertaken to fully embrace the question, challenging Medline at the National Library of Medicine, Cochrane Library, National Guideline Clearinghouse, Health Technology Assessment Database. All the retrieved articles were classified as either descriptive or comparative studies and evaluated on a set of criteria. Most of the papers described case series coming from a few teams, focusing mainly on the technical aspect of the procedure, like the access rate to the posterior cul-de-sac, the success rate in visualizing the pelvis, the complications rate (mainly rectal perforation), and its operative performance in drilling ovaries for resistant polycystic ovarian syndrome. Comparative studies numbered six trials. They all followed the same design, fertiloscopy preceding conventional laparoscopy in patients taken as their own control. The concordance rate between the two modalities reaches 80% in terms of tubal pathology, adherences and endometriosis, with an estimated reduction of laparoscopies varying from 40% to 93%. The current literature shows a concordance between fertiloscopy and conventional laparoscopic findings for certain parameters in cases of tubal pathology, adherences and endometriosis. The relative positions of these two modalities in unexplained infertility still remain elusive. Copyright © 2014. Published by Elsevier Masson SAS.

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

PubMed

Baack Kukreja, Janet E; Messing, Edward M; Shah, Jay B

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.

Risks and benefits of opportunistic salpingectomy during vaginal hysterectomy: a decision analysis.

PubMed

Cadish, Lauren A; Shepherd, Jonathan P; Barber, Emma L; Ridgeway, Beri

2017-11-01

Fallopian tubes are commonly removed during laparoscopic and open hysterectomy to prevent ovarian and tubal cancer but are not routinely removed during vaginal hysterectomy because of perceptions of increased morbidity, difficulty, or inadequate surgical training. We sought to quantify complications and costs associated with a strategy of planned salpingectomy during vaginal hysterectomy. We created a decision analysis model using TreeAgePro. Effectiveness outcomes included ovarian cancer incidence and mortality as well as major surgical complications. Modeled complications included transfusion, conversion to laparotomy or laparoscopy, abscess/hematoma requiring intervention, ileus, readmission, and reoperation within 30 days. We also modeled subsequent benign adnexal surgery beyond the postoperative window. Those whose procedures were converted from a vaginal route were assumed to undergo bilateral salpingectomy, regardless of treatment group, following American College of Obstetricians and Gynecologists guidelines. Costs were gathered from published literature and Medicare reimbursement data, with internal cost data from 892 hysterectomies at a single institution used to estimate costs when necessary. Complication rates were determined from published literature and from 13,397 vaginal hysterectomies recorded in the National Surgical Quality Improvement Program database from 2008 through 2013. Switching from a policy of vaginal hysterectomy alone to a policy of routine planned salpingectomy prevents a diagnosis of ovarian cancer in 1 of every 225 women having surgery and prevents death from ovarian cancer in 1 of every 450 women having surgery. Overall, salpingectomy was a less expensive strategy than not performing salpingectomy ($7350.62 vs $8113.45). Sensitivity analysis demonstrated the driving force behind increased costs was the increased risk of subsequent benign adnexal surgery among women retaining their tubes. Planned opportunistic salpingectomy had more major complications than hysterectomy alone (7.95% vs 7.68%). Major complications included transfusion, conversion to laparotomy or laparoscopy, abscess/hematoma requiring intervention, ileus, readmission, and reoperation within 30 days. Therefore, routine salpingectomy results in 0.61 additional complications per case of cancer prevented and 1.21 additional complications per death prevented. A surgeon therefore must withstand an additional ∼3 complications to prevent 5 cancer diagnoses and ∼6 additional complications to prevent 5 cancer deaths. Salpingectomy should routinely be performed with vaginal hysterectomy because it was the dominant and therefore cost-effective strategy. Complications are minimally increased, but the trade-off with cancer prevention is highly favorable. Copyright © 2017 Elsevier Inc. All rights reserved.

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.

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

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.

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: To compare outcomes of two different types of occlusive therapy of uterine fibroids. Methods: Women with fibroid(s) unsuitable for laparoscopic myomectomy (LM) were treated with uterine artery embolization (UAE) or laparoscopic uterine artery occlusion (LUAO). Results: Before the procedure, patients treated with UAE (n = 100) had a dominant fibroid greater in size (68 vs. 48 mm) and a mean age lower (33.1 vs. 34.9 years) than surgically treated patients (n = 100). After 6 months, mean shrinkage of fibroid volume was 53 % after UAE and 39 % after LUAO (p = 0.063); 82 % of women aftermore » UAE, but only 23 % after LUAO, had complete myoma infarction (p = 0.001). Women treated with UAE had more complications (31 vs. 11 cases, p = 0.006) and greater incidence of hysteroscopically verified intrauterine necrosis (31 vs. 3 %, p = 0.001). Both groups were comparable in markers of ovarian functions and number of nonelective reinterventions. The groups did not differ in pregnancy (69 % after UAE vs. 67 % after LUAO), delivery (50 vs. 46 %), or abortion (34 vs. 33 %) rates. The mean birth weight of neonates was greater (3270 vs. 2768 g, p = 0.013) and the incidence of intrauterine growth restriction lower (13 vs. 38 %, p = 0.046) in post-UAE patients. Conclusion: Both methods are effective in the treatment of women with future reproductive plans and fibroids not suitable for LM. UAE is more effective in causing complete ischemia of fibroids, but it is associated with greater risk of intrauterine necrosis. Both methods have low rate of serious complications (except for a high abortion rate).« less

Possible effects of repeated hormonal treatments and laparoscopic ovum pick-up (LOPU) on the efficiency of oocyte recovery rate and quality were determined in sheep and goats. In six adult Merino sheep and five Criolla goats, ovarian status was synchronized by a prostaglandin F(2 alpha) analogue and the insertion of an intravaginal sponge 48 h later. Follicle development was stimulated by a single dose of FSH (60 mg NIH-FSH-P1) plus a single dose of equine chorionic gonadotrophin (eCG; 300 UI). The first FSH/eCG doses were administered 48 h after the sponge insertion, being repeated every 4 days to complete a total of four treatments in sheep and three in goats. Follicles in both ovaries were categorized according to their diameter and follicular fluid was aspirated under laparoscopic observation without a vacuum pump. In sheep, during a 12-day-period, a total of 347 follicles were aspirated with a recovery rate of 46.9%. In goats, during an 8-day-period, 219 follicles were aspirated with a recovery rate of 45.6%. In both species, there were no significant differences in the number of aspirated follicles, oocyte recovery rate and good quality oocyte recovery rate. However, in sheep the oocyte recovery rate was higher for large follicles, whereas in goats no such effect was detected. In summary, current results indicate that retrieval of oocytes can be maximized, without affecting oocyte quality, by repeating 'oneshot' FSH/eCG regimes and LOPUs at intervals as short as 4 days.

Gastric cancer remains one of the most aggressive malignancies, being associated with very poor therapeutic outcomes, especially in the advanced disease patients. Due to this evidence, finding a better treatment, a better control and higher survival rates is the current scientific focus of the medical community. Once the benefits of cytoreductive surgery in association with intraperitoneal hyperthermy (HIPEC) have been widely demonstrated in patients presenting peritoneal carcinomatosis from colorectal or ovarian origin,attention was focused on the possible benefit of this method in patients diagnosed with peritoneal carcinomatosis with gastric origin. Moreover, using laparoscopy for the cytoreductive surgery (L-CRS) and hyperthermic intraperitoneal chemotherapy (L-HIPEC), the advantages of minimal invasive surgery (MIS) are expected to contribute to improved postoperative outcomes. In this way, the patients benefit from a faster administration of the adjuvant chemotherapeutic treatment, whenever is necessary. to present the technique of L-CRS + L-HIPEC and the early therapeutic outcomes in a case series of two patients diagnosed with peritoneal carcinomatosis from gastric cancer. A complete investigational work-up including diagnostic laparoscopy to evaluate the Peritoneal Carcinomatosis Index (PCI) was fulfilled in all the cases. The institutional Tumor Board decided the therapeutic strategy: laparoscopic radical resection and HIPEC (L-CRS +L-HIPEC). The procedures were performed into a private setting (Ponderas Academic Hospital). Results: Two male patients,46 and 69years old, presenting carcinomatosis from gastric cancer were included into the study. Initial PCI was assessed by laparoscopy and it was 18 and 7, respectively. Both cases underwent neoadjuvant chemotherapy. D2 laparoscopic radical gastrectomy and L-HIPEC was then performed. Time of procedure was360 and 320 minutes, respectively. The intraperitoneal temperature varied between 41 and 42°C, while the intra-esophageal temperature reached a maximum value of 37,7 °C. There was no perioperative or postoperative complication, nor mortality. The hospital stay was 8 days. Conclusions: Explorative laparoscopy can help select patients for conversion chemotherapy in the setting of high peritoneal carcinomatosis index (PCI) score. Laparoscopy radical excision + L-HIPEC were successfully performed with very good therapeutic outcomes. Celsius.

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 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.

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.

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.

What is the effect of basic fibroblast growth factor (bFGF) on the growth of individual early human follicles in a three-dimensional (3D) culture system in vitro? The addition of 200 ng bFGF/ml improves human early follicle growth, survival and viability during growth in vitro. It has been demonstrated that bFGF enhances primordial follicle development in human ovarian tissue culture. However, the growth and survival of individual early follicles in encapsulated 3D culture have not been reported. The maturation in vitro of human ovarian follicles was investigated. Ovarian tissue (n= 11) was obtained from 11 women during laparoscopic surgery for gynecological disease, after obtaining written informed consent. One hundred and fifty-four early follicles were isolated by enzymic digestion and mechanical disruption. They were individually encapsulated into alginate (1% w/v) and randomly assigned to be cultured with 0, 100, 200 or 300 ng bFGF/ml for 8 days. Individual follicles were cultured in minimum essential medium α (αMEM) supplemented with bFGF. Follicle survival and growth were assessed by microscopy. Follicle viability was evaluated under confocal laser scanning microscope following Calcein-AM and Ethidium homodimer-I (Ca-AM/EthD-I) staining. After 8 days in culture, all 154 follicles had increased in size. The diameter and survival rate of the follicles and the percentage with good viability were significantly higher in the group cultured with 200 ng bFGF/ml than in the group without bFGF (P < 0.05). The percentage of follicles in the pre-antral stage was significantly higher in the 200 ng bFGF/ml group than in the group without bFGF (P < 0.05), while the percentages of primordial and primary follicles were significantly lower (P < 0.05). The study focuses on the effect of bFGF on the development of individual human early follicles in 3D culture in vitro and has limited ability to reveal the specific effect of bFGF at each different stage. The findings highlight the need to improve the acquisition and isolation of human ovarian follicles. The in vitro 3D culture of human follicles with appropriate dosage of bFGF offers an effective method to investigate their development. Moreover, it allows early follicles to be cultured to an advanced stage and therefore has the potential to become an important source of mature oocytes for assisted reproductive technology; particularly as an option for fertility preservation in women, including patients with cancer. This work was supported by the National Basic Research Program of China (2011|CB944504, 2011CB944503) and the National Natural Science Foundation of China (81200470, 81000275, 31230047, 8110197).

Metabolic syndrome is an increasing pathology in adults and in children, due to a parallel rise of obesity. Sedentary lifestyle, food habits, cultural influences and also a genetic predisposition can cause dyslipidemia, hypertension, abdominal obesity and insulin resistance which are the two main features of metabolic syndrome. Polycystic ovary syndrome (PCOS) is a condition directly associated with obesity, insulin resistance (HOMA index) and metabolic syndrome, and it is very interesting for its relationship and overlap with the metabolic syndrome. The relationship between the two syndromes is mutual: PCOS women have a higher prevalence of metabolic syndrome and also women with metabolic syndrome commonly present the reproductive/endocrine trait of PCOS. Prevention and treatment of metabolic syndrome and PCOS are similar for various aspects. It is necessary to treat excess adiposity and insulin resistance, with the overall goals of preventing cardiovascular disease and type 2 diabetes and improving reproductive failure in young women with PCOS. First of all, lifestyle changes, then pharmacological therapy, bariatric surgery and laparoscopic ovarian surgery represent the pillars for PCOS treatment.

Most of the ovarian cancers are diagnosed at advanced stages. As peritoneal carcinomatosis increases, especially when it extends to the diaphragm and intestinal mesos, probability of obtaining complete cytoreduction is reduced. Complete cytoreduction (residue zero: R0) is one of the main factors affecting survival [1-3]. Here we present a novel technique of stripping the peritoneal surfaces as a part of cytoreductive surgery in such cases. A 55year-old woman diagnosed with peritoneal carcinomatosis was considered appropriate for primary cytoreduction after assessment of her thorax-abdominopelvic tomography, which revealed resectable intra-abdominal disease. Upon laparotomy, omental cake adherent to pelvis-filling mass, disseminated implants on the diaphragm, meso of the descending colon and small intestine were observed. The mass invaded the rectosigmoid colon, uterus, adnexa and the bladder resulting in frozen pelvis. Palpable retroperitoneal pelvic and para-aortic lymph nodes were detected. On the other side, stomach, anti-mesenteric surfaces and mesentery root of the small bowel were tumor-free. Hence, upon these perioperative and preoperative imaging findings, complete cytoreduction was thought to be achievable. Therefore, primary cytoreduction was performed. Total omentectomy, hysterectomy with bilateral salpingo-oophorectomy, rectosigmoid low anterior resection and retroperitoneal lymphadenectomy were performed. With the assistance of an injector needle connected to the insufflator tube (as in laparoscopic surgery), carbon dioxide gas was blown into the right retroperitoneal area and subsequently peritoneum was rapidly stripped up to the right diaphragm. The same procedure was then applied to the diaphragm and meso of the bowels, respectively. Owing to this technique, total stripping of all involved peritoneal surfaces was clearly facilitated and R0 goal was reached. Gas insufflation caused convenient detachment of the peritoneal surfaces along their anatomical line which led to concluding the stripping procedures easily, rapidly and safely without bleeding. Thus, according to our experience, about 10 to 15min per procedure are saved in such cases. Potential complications of CO 2 gas used here are not superior to those in transperitoneal or retroperitoneal laparoscopic procedures. During the operation, patient was followed-up for potential complications such as subcutaneous emphysema and CO 2 gas embolism.Thus, hourly blood gas was monitored. Another potential complication is injury of the vessels while inserting the needle which can be avoided by cautious inserting under the peritoneal surfaces superficially and using transillumination. In case such injuries happen, tamponing is a sufficient measure. In our serial, no perioperative complications belonging to this technique were encountered. However, long term outcomes such as precise time difference, difference in blood loss, complication rates, adhesions, morbidity associated with this technique and its impact on survival of the patients with advanced ovarian cancer have yet to be investigated. Therefore, a prospective study to validate this technique's long-term usefulness has been initiated in our clinic. We believe that this practical and effective technique will offer significant improvements in efforts to achieve complete cytoreduction. Copyright © 2017 Elsevier Inc. All rights reserved.

Surgery is the cornerstone for clinical management of patients with borderline ovarian tumors (BOT). As these patients have an excellent overall prognosis, perioperative morbidity is the critical point for decision making when the treatment strategy is developed and the primary surgical approach is defined. Clinical and surgical parameters of patients undergoing surgery for primary BOT at our institutions between 1993 and 2008 were analyzed with regard to perioperative morbidity depending on the surgical approach (laparotomy vs. laparoscopy). A total of 105 patients were analyzed (44 with primary laparoscopy [42%], 61 with primary laparotomy [58%]). Complete surgical staging was achieved in 33 patients at primary surgical approach (31.4%) frequently leading to formal indication of re-staging procedures. Tumor rupture was significantly more frequent during laparoscopy compared to laparotomy (29.5% vs. 13.1%, p = 0.038) but no other intraoperative complications were seen in laparoscopic surgery in contrast to 7 of 61 laparotomies (0% vs. 11.5%, p = 0.020). Postoperative complication rates were similar in both groups (19.7% vs. 18.2%, p = 0.848). Irrespective of the surgical approach, surgical management of BOT has acceptable rates of perioperative complications and morbidity. Choice of initial surgical approach can therefore be made independent of complication-concerns. As the recently published large retrospective AGO ROBOT study observed similar oncologic outcome for both approaches, laparoscopy can be considered for staging of patients with BOT if this appears feasible. An algorithm for the surgical management of BOT patients has been developed.

This work is a topic highlight on the surgical treatment of the right colon pathologies, focusing on the literature state of art and comparing the open surgery to the different laparoscopic and robotic procedures. Different laparoscopic procedures have been described for the treatment of right colon tumors: Totally laparoscopic right colectomy, laparoscopic assisted right colectomy, laparoscopic facilitated right colectomy, hand-assisted right colectomy, single incision laparoscopic surgery colectomy, robotic right colectomy. Two main characteristics of these techniques are the different type of anastomosis: Intracorporeal (for totally laparoscopic right colectomy, single incision laparoscopic surgery colectomy, laparoscopic assisted right colectomy and robotic technique) or extracorporeal (for laparoscopic assisted right colectomy, laparoscopic facilitated right colectomy, hand-assisted right colectomy and open right colectomy) and the different incision (suprapubic, median or transverse on the right side of abdomen). The different laparoscopic techniques meet the same oncological criteria of radicalism as the open surgery for the right colon. The totally laparoscopic right colectomy with intracorporeal anastomosis and even more the single incision laparoscopic surgery colectomy, remain a technical challenge due to the complexity of procedures (especially for the single incision laparoscopic surgery colectomy) and the particular right colon vascular anatomy but they seem to have some theoretical advantages compared to the other laparoscopic and open procedures. Data reported in literature while confirming the advantages of laparoscopic approach, do not allow to solve controversies about which is the best laparoscopic technique (Intracorporeal vs Extracorporeal Anastomosis) to treat the right colon cancer. However, the laparoscopic techniques with intracorporeal anastomosis for the right colon seem to show some theoretical advantages (functional, technical, oncological and cosmetic advantages) even if all studies conclude that further prospective randomized trials are necessary. Robotic technique may be useful to overcome the problems related to inexperience in laparoscopy in some surgical centers. PMID:27648160

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

The Will Rogers phenomenon in urological oncology.

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: 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

Laparoscopic trocar-site hernias (TSH) are rare, with a reported incidence of 1% or less. The incidence of occult radiographically evident hernias has not been described after robot-assisted urologic surgery. We evaluated the incidence and risk factors of this problem. A single-institution retrospective review of robot-assisted urologic surgery was performed from April 2009 to December 2012. Patients with preoperative and postoperative CT were included for analysis. Imaging was reviewed by two radiologists and one urologist. One hundred four cases were identified, including 60 partial nephrectomy, 38 prostatectomy, and 6 cystectomy. Mean age was 58 years and mean body mass index (BMI) was 29 kg/m(2). The cohort was 77% male. Ten total hernias were identified by CT in 8 patients, 2 of which were clinically evident hernias. Excluding these two hernias, occult port-site hernias were identified radiographically in seven patients. Per-patient incidence of occult TSH was 6.7% (7/104), and per-port incidence was 1.4% (8/564). All hernias were midline and 30% contained bowel. Eight of the 10 occurred at 12 mm sites (p = 0.0065) and 3 of the 10 occurred at extended incisions. Age, gender, BMI, smoking status, diabetes mellitus, immunosuppressive drug therapy, ASA score, procedure, blood loss, prior abdominal surgery, and history of hernia were not significant risk factors. Specimen size >40 g (p = 0.024) and wound infection (p = 0.0052) were significant risk factors. While the incidence of clinically evident port-site hernia remains low in robot-assisted urologic surgery, the incidence of CT-detected occult hernia was 6.7% in this series. These occurred most often in sites extended for specimen extraction and at larger port sites. This suggests more attention should be paid to fascial closure at these sites.

To compare surgical outcomes, including renal function and the preserved renal parenchymal volume, between robot-assisted laparoscopic partial nephrectomy and laparoscopic partial nephrectomy using propensity score-matched analyses. In total, 253 patients, with a normal contralateral kidney, who underwent laparoscopic partial nephrectomy (n = 131) or robot-assisted laparoscopic partial nephrectomy (n = 122) with renal arterial clamping between 2010 and 2015, were included. Patients' background and tumor factors were adjusted by propensity score matching. Surgical outcomes, including postoperative renal function, complications, warm ischemia time and preserved renal parenchymal volume, evaluated by volumetric analysis, were compared between the surgical procedures. After matching, 64 patients were assigned to each group. The mean age was 56-57 years, and the mean tumor size was 22 mm. Approximately 50% of patients had low complexity tumors (RENAL nephrometry score 4-7). The incidence rate of acute kidney failure was significantly lower in the robot-assisted laparoscopic partial nephrectomy (11%) than laparoscopic partial nephrectomy (23%) group (P = 0.049), and warm ischemia time shorter in the robot-assisted laparoscopic partial nephrectomy (17 min) than laparoscopic partial nephrectomy (25 min) group (P < 0.0001). The preservation rate of renal function, measured by the estimated glomerular filtration rate, at 6 months post-surgery was 96% for robot-assisted laparoscopic partial nephrectomy and 90% for laparoscopic partial nephrectomy (P < 0.0001). The preserved renal parenchymal volume was higher for robot-assisted laparoscopic partial nephrectomy (89%) than laparoscopic partial nephrectomy (77%; P < 0.0001). The rate of perioperative complications, surgical margin status and length of hospital stay were equivalent for both techniques. Robot-assisted laparoscopic partial nephrectomy allows to achieve better preservation of renal function and parenchymal volume than laparoscopic partial nephrectomy. © 2018 The Japanese Urological Association.

Laparoscopy has been a standard procedure in most medical centres providing surgical services for many years. Both the range and number of laparoscopic procedures performed are constantly increasing. Over the last decade, laparoscopic procedures have been successfully applied both in emergency and oncological surgery. However, treatment costs have become a more important factor in choosing between open or laparoscopic procedures. To present the total real costs of open and laparoscopic cholecystectomy, appendectomy and sigmoidectomy. Between 1 May 2010 and 30 March 2015 in the Department of Thoracic Surgery, General and Oncological Surgery, Medical University of Lodz, and in the Department of General Surgery of the Saint John of God Hospital, Lodz, doctors performed 1404 cholecystectomies, 392 appendectomies and 88 sigmoidectomies. A total of 97% of the cholecystectomy procedures were laparoscopic and 3% were open. Similarly, 22% of total appendectomies were laparoscopic and 78% were open, while 9% of sigmoidectomies were laparoscopic and 91% open. The requirement for single-use equipment in laparoscopic procedures increases the expense. However, after adding up all other costs, surprisingly, differences between the costs of laparoscopic and open procedures ranged from 451 PLN/€ 114 for laparoscopic operations to 611 PLN/€ 153 for open operations. Laparoscopic cholecystectomy, considered the standard surgery for treating gallbladder diseases, is cheaper than open cholecystectomy. Laparoscopic appendectomy and sigmoidectomy are safe methods of minimally invasive surgery, slightly more expensive than open operations. Of all the analyzed procedures, one-day laparoscopic cholecystectomy is the most profitable. The costs of both laparoscopic and open sigmoidectomy are greatly underestimated in Poland.

Torsion of normal adnexa in postmenarcheal women: can ultrasound indicate an ischemic process?

Torsion of normal adnexa is a rare event involving steadily increasing congestion and ischemia of the ovary. We investigated whether this process can be characterized by sonographic features. Twelve menstrually cycling women with 14 separate episodes of laparoscopic-proven torsion of normal adnexa were identified retrospectively, and the results of their preoperative gray-scale ultrasound examinations and Doppler flow evaluations were analyzed. The cases were classified into 'short-term' (< 24 h; range, 3-24 h) and 'prolonged' (> 24 h; range, 1-10 days) duration of torsion according to the reported period of abdominal pain before admission. Absence of any additional adnexal pathology was confirmed by both intraoperative inspection and postoperative follow-up ultrasound examinations. The median age of the cohort was 24.0 (interquartile range (IQR), 20.5-28.7) years, and parity ranged from 0 to 3. All affected ovaries were significantly enlarged compared with non-affected ones (median cross-sectional area, 18.1 (IQR, 12.4-26.4) cm(2) vs. 4.3 (IQR, 2.9-6.2) cm(2), P < 0.01). We could distinguish two distinct sonographic patterns of torted ovaries: there were numerous small peripheral follicles in the ovarian parenchyma in nine cases, and there was a solid-appearing mass with hypo- and hyperechogenic foci in five cases. Comparison of the ultrasound images of patients with short-term vs. long-term abdominal pain revealed that the solid-appearing ovary was more common in the latter group (0/6 vs. 5/8, P = 0.03), while there was no significant difference between groups in the presence of free pelvic fluid or median ovarian cross-sectional area. Intraovarian blood flow was diminished or absent in five of the eight patients in whom color Doppler imaging was performed. Ultrasound images of twisted normal adnexa may vary according to the duration of the condition, reflecting the pathological series of events of increased ovarian congestion and necrosis. Recognition of the different sonographic features of twisted normal adnexa may assist in the correct diagnosis of these patients. (c) 2008 ISUOG. Published by John Wiley & Sons, Ltd.

To identify learning curves for single-port laparoscopic myomectomy (SPLM) and evaluate surgical outcomes according to the sequence of operation. A retrospective study. A university-based hospital (Canadian Task Force classification II-2). The medical records from 205 patients who had undergone SPLM from October 2009 to May 2013 were reviewed. Because the myomectomy time was significantly affected by the size and number of myomas removed by SPLM, cases in which 2 or more of the myomas removed were >7 cm in diameter were excluded. Furthermore, cases involving additional operations performed simultaneously (e.g., ovarian or hysteroscopic surgery) were also excluded. A total of 161 cases of SPLM were included. None. We assessed the SPLM learning curve via a graph based on operation time versus sequence of cases. Patients were chronologically arranged according to their surgery dates and were then placed into 1 of 4 groups according to their operation sequence. SPLM was completed successfully in 160 of 161 cases (99.4%). One case was converted to multiport surgery. Basal characteristics of the patients between the 4 groups did not differ. The median operation times for the 4 groups were 112.0, 92.8, 83.7, and 90.0 minutes, respectively. Operation time decreased significantly in the second, third, and fourth groups compared with that in the first group (p < .001). Proficiency, which is the point at which the slope of the learning curve became less steep, was evident after about 45 operations. Results from the current study suggested that proficiency for SPLM was achieved after about 45 operations. Additionally, operation time decreased with experience without an increase in complication rate. Copyright © 2015 AAGL. Published by Elsevier Inc. All rights reserved.

Isolated fallopian tube torsion in pediatric and adolescent females: a retrospective review of 15 cases at a single institution.

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.

We present the outcomes of modification of cutaneous ureterostomy by extreme lateralization of the stoma and use of skin flap for formation of ureterostomy. Between June 2012 and June 2016, 36 patients had modified cutaneous ureterostomy for ureteral obstruction due to pelvic malignancy or genitourinary tuberculosis. Transureteroureterostomy was made with cutaneous stoma at anterior axillary line between iliac crest and lower rib cage, instead of spinoumbilical line. To prevent stenosis a 'V' shaped skin was fed into the stoma. Double J stents were used in all patients for 6 weeks. Perioperative morbidity and mortality were evaluated. All patients were followed up at 3 month intervals. Of 36 patients, 22 had radical cystoprostatectomy (including nephroureterectomy in 2 patients) and 7 had palliative cystectomy. Others had locally advanced prostate cancer (n=1), locally advanced cervical cancer (n=3), ovarian cancer (n=1) and genitourinary tuberculosis with small capacity bladder along with a large vesicovaginal fistula (n=1). One patient developed ureteral necrosis requiring conversion to ileal conduit. Three patients developed stomal stenosis: two were managed by self-dilatation while one required revision of stoma. Thirteen patients died of the disease at a median follow up of 6 months with functioning stoma. Remaining 19 patients survived without any complications at a median follow-up of 20.5 months (5.5-43.5 months). None of the patients had any problem related to ureterostomy bag application. Modified lateral cutaneous ureterostomy provides relatively straighter and shorter retroperitoneal course of ureter with acceptable morbidity and avoids use of bowel in selected patients.

In mammals, recovery of oocytes by laparoscopic ovum pick-up (LOPU) coupled with in vitro production (IVP) of embryos represents a promising strategy for both amplification and genetic management of sparse animals from captive endangered wild species. As integrated technique developed mainly for domestic livestock, LOPU-IVP requires several studies to set up protocols for follicular stimulation or optimization of IVP before envisaging successful transposition to wild species. In deer, many endangered subspecies would be potentially concerned by applying such an approach using common subspecies for protocols optimization. The aim of the present study was to assess efficiency of follicle stimulation using ovine FSH (oFSH) for recovery of oocytes by LOPU in common sika deer (Cervus nippon nippon) before transposition of an optimized methodology for IVP of embryos from endangered Vietnamese sika deer hinds (Cervus nippon pseudaxis). In common sika deer, two doses of oFSH (0.25 and 0.5 U) and two frequencies of administration (12 and 24 h) were compared by monitoring of subsequent ovarian response, quality of oocytes recovered by LOPU, and in vitro developmental competence. In a first experiment, the dose of oFSH administered did not significantly affect the total number of follicles aspirated per hind per session (8.6 ± 1.0 vs. 8.2 ± 1.6 with 0.5 vs. 0.25 U oFSH, respectively; not significant). In a second experiment, frequency of 0.25 U oFSH administration did not affect ovarian response. Efficiency of IVP determined on blastocysts rates after in vitro maturation, fertilization, and development in oviduct epithelial cells coculture was increased when FSH was administered at 12-h intervals. Immune response after several follicular stimulations was detected against exogenous oFSH in plasma from the majority of sika deer hinds but was not associated with decreased ovarian response. When 0.25 U oFSH was administered at 12-h intervals to Vietnamese sika deer (N = 4), good quality cumulus oocyte complexes with complete and compact cumulus investments were recovered allowing a high cleavage rate after in vitro maturation and fertilization. Development to the blastocyst stage occurred in a high proportion (30% of oocytes) after coculture with ovine epithelial cells allowing cryobanking of transferable embryos from Vietnamese sika deer. These results confirm that LOPU-IVF after ovarian stimulation with oFSH may be a successful tool for cryobanking transferable embryos from endangered sika deer subspecies.

Laparoscopic adrenalectomy is considered the standard technique for the surgical removal of the adrenal gland. This report is about a 4-year single experience in our Endocrine and General Surgery Unit with laparoscopic adrenalectomy. A total of 24 lateral transperitoneal laparoscopic adrenalectomies were performed. The indications for laparoscopic surgery were: aldosteronoma in 3 patients, pheochromocytoma in 6 patients, nonfunctioning adenoma in 6 patients, adenoma causing Cushing's syndrome in 3 patients, 1 lymphangioma-like adenomatoid tumor, 1 myelolipoma, 1 complicated adrenal cyst, 2 adrenocortical carcinomas, 1 lung metastasis. All except two had successful laparoscopic adrenalectomy. Complication occurred in one patient. 3 patients underwent other associated laparoscopic procedures. Operative time ranged from 100 to 240 minutes for laparoscopic adrenalectomy, from 180 to 210 minutes in the cases with two associated laparoscopic procedures, 5 hours for bilateral adrenalectomy; the postoperative hospital stay for laparoscopic adrenalectomy ranged from 4 to 8 days (6,79 days) and from 7 to 13 days (9,12 days) for patients undergoing the open or converted procedure. Laparoscopic adrenalectomy is technically feasible and reproducible. We evaluate the effectiveness of laparoscopic adrenalectomy for a variety of endocrine disorders except in the case of invasive carcinoma or large masses. Antonio Cardarelli Endocrine and General Surgery Unit in Naples is known as a specialized center for thyroid and parathyroid surgery; in future, we could also become a high-volume laparoscopic referral center for adrenal gland pathologies.

The challenges in laparoscopic suturing include need to expertise to suture. Laparoscopic needle holder is a" key" instrument to accomplish this arduous task. The objective of this new invention was to develop a laparoscopic needle holder which would be adapted to avoid any wobble (with a shaft diameter same as a 5mm port), ensure accurate and dexterous suturing not just in adult patients but pediatric patients alike (with a short shaft diameter) and finally ensure seamless throw of knots with a narrow tip configuration. We did an initial evaluation to evaluate the validity of the prototype needle holder and its impact on laparoscopic suturing skills by experienced laparoscopic surgeons and novice laparoscopic Surgeons. Both the groups of surgeons performed two tasks. The first task was to grasp the needle and position it in an angle deemed ideal for suturing. The second task was to pass suture through two fixed points and make a single square knot. At the end of the tasks each participant was asked to complete a 5- point Likert's scale questionnaire (8 items; 4 items of handling and 4 items of suturing) rating each needle holder. In expert group, the mean time to complete task 1 was shorter with prototype 3/5 laparoscopic needle holder (11.8 sec Vs 20.8 sec). The mean time to complete task 2 was also shorter with prototype 3/5 laparoscopic needle holder (103.2 sec Vs 153.2 sec). In novice group, mean time to complete both the task was shorter with prototype 3/5 laparoscopic needle holder. The expert laparoscopic surgeons as well as novice laparoscopic surgeons performed laparoscopic suturing faster and with more ease while using the prototype 3/5 laparoscopic needle holder.

The place of laparoscopic repair of perforated peptic ulcer followed by peritoneal toilet has been established, although it is not routinely practiced. This prospective study compared laparoscopic and open repair of perforated peptic ulcer disease. We evaluated whether the early results from laparoscopic repair resulted in improved patient outcome compared with conventional open repair. All patients who underwent repair of perforated peptic ulcer disease during a 12-month period in our unit were included in the study. The primary end points that were evaluated were total operative time, nasogastric tube utilisation, intravenous fluid requirement, total time of urinary catheter and abdominal drainage usage, time taken to return to normal diet, intravenous/intramuscular opiate use, time to full mobilization, and total in-patient hospital stay. Thirty-three patients underwent surgical repair of perforated peptic ulcer disease (19 laparoscopic repairs and 14 open repairs; mean age, 54.2 (range, 32-82) years). There was no increase in total operative time in patients who had undergone laparoscopic repair (mean: 61 minutes laparoscopic versus 57 minutes open). There was significantly less requirement for intravenous/intramuscular opiate analgesia in patients who had undergone laparoscopic repair (mean time to oral analgesia: 1.2 days laparoscopic versus 3.8 days open). In addition there was a significant decrease in the time that the nasogastric tube (mean: 2.1 days laparoscopic versus 3.1 days open), urinary catheter (mean: 2.3 days laparoscopic versus 3.7 days open) and abdominal drain (mean: 2.2 days laparoscopic versus 3.8 days open) were required during the postoperative period. Patients who had undergone laparoscopic repair required less intravenous fluids (mean: 1.4 days laparoscopic versus 3.1 days open) and returned to normal diet (mean: 2.3 days laparoscopic versus 4.8 days open) and full mobilization significantly earlier than those who had undergone open repair (mean: 2.3 days laparoscopic versus 3.3 days open). In addition, patients who had undergone laparoscopic repair required a shorter in-patient hospital stay (mean: 3.1 days laparoscopic versus 4.3 days open). Laparoscopic repair is a viable and safe surgical option for patients with perforated peptic ulcer disease and should be considered for all patients, providing that the necessary expertise is available.

Of this study is the introduction and the results evaluation of laparoscopic ultrasonography performed. We realize a prospective study about laparoscopic ultrasonography performed in 37 cases with laparoscopic surgical treatment. The Aloka SSD 2000 mobile scanner is used. This system make possible the use of an linear-array transducer, with mechanical flexibility and availability of Doppler analysis. Most frequently we used intraoperative ultrasonography in laparoscopic cholecystectomy as an alternative for cholangiography to exclude CBD pathology. Because of various surgical pathology with laparoscopic approach, the laparoscopic ultrasonography utilization range was vastly. In all the cases we could performed the laparoscopic ultrasonography. In 6 of 27 cases with laparoscopic cholecystectomy we found pathological disorders of bile ducts. CBD with diameter found between 5-12 mm. We properly saw the distal segment of CBD in 23 cases (89.2%), and common hepatic duct in 26 cases (97.3%). The quality of visualization was very good in 21 cases (83.8%) and moderate in 6 cases (16.2%). We easy identify CBD stones and we successfully used Doppler color mode in differentiating vascular from non-vascular from non-vascular structures. Laparoscopic ultrasonography performed in a case with left colon cancer excluded liver metastasis and lymph nodes metastasis. 1. Laparoscopic ultrasonography combines the advantages of diagnostic laparoscopy and intraoperative contact ultrasonography; 2. Laparoscopic ultrasonography is a simple and very efficient intraoperative examination procedure; 3. Laparoscopic ultrasonography is the technique to choose in CBD intraoperative exploration; 4. Laparoscopic ultrasonography improve abdominal malignancy exploration, thus modifying therapeutic decisions; 5. Color Doppler mode guides the surgeon's steps in difficult directions.

Laparoscopic and thoracoscopic/laparoscopic hepatectomy is a safe procedure that has potential advantages over open surgery. However, deeply positioned liver tumors require expert laparoscopic and thoracoscopic/laparoscopic hepatectomy techniques. Using simulated preoperative three-dimensional virtual endoscopy (P3DVE) guidance, we demonstrate herein that a thoracoscopic approach (TA), thoracoscopic-laparoscopic approach (TLA), and laparoscopic approach (LA) are all feasible and safe routes for performing pure laparoscopic and thoracoscopic/laparoscopic resection of liver tumors located in the 4a, 7, and 8 liver subdiaphragmatic areas. Thirty-eight patients underwent laparoscopic and thoracoscopic/laparoscopic partial liver resection (TA 13 cases, TLA two cases, and LA 23 cases) of the subdiaphragmatic area at Showa University Hospital. All surgical approaches were preoperatively determined based on preoperative 3D virtual endoscopic simulation (P3DVES) visualization and findings using the image processing software SYNAPSE VINCENT(®). Laparoscopic and thoracoscopic/laparoscopic liver resection was successfully performed for all cases under P3DVE instruction. The mean operative times using TA, TLA, and LA approaches were 193, 185, and 190 min, respectively. Mean blood loss during TA, TLA, and LA was 179, 138, and 73 g, respectively. No patients required conversion to open surgery, and there were no deaths, although there were three cases of Clavien-Dindo grade I in TA along with three cases of grade I and one case of grade II in LA. TA, TLA, and LA routes performed under P3DVE instruction are feasible and safe to perform for pure laparoscopic and thoracoscopic/laparoscopic liver resection in selected patients with lesions located in the hepatic subdiaphragmatic area.

To study the clinical effect of gasless-laparoscopic vaginoplasty using sigmoid colon segment. Clinical data of 119 cases undergoing laparoscopic or gasless-laparoscopic vaginoplasty using a vascularized pedicled sigmoid colon segment in Beijing Anzhen Hospital from January 2007 to December 2010 were reviewed retrospectively. Those patients were classified into 57 cases with laparoscopic sigmoid colon vaginoplasty and 62 cases with gasless-laparoscopic sigmoid colon vaginoplasty. The operation time, blood loss in operating, bowel movement after operation, postoperation hospital duration, side effect, and artificial vagina were compared between laparoscopic and gasless-laparoscopic group. The vaginoplasty were preformed successfully in 119 cases. The mean operation time of were (159 ± 18) min in laparoscopic group and (146 ± 17) min in gasless-laparoscopic group, respectively, which reached statistical difference (P < 0.01). The blood loss in operating were (83 ± 14) ml and (86 ± 13) ml, bowel movement after operation were (68 ± 8) hours and (68 ± 11) hours, and postoperation hospital duration were (11.1 ± 1.3) days and (11.4 ± 1.9) days respectively in laparoscopic group and gasless-laparoscopic group. No significant difference were found in the blood loss in operating, bowel movement after operation, and postoperation hospital duration between two groups (P > 0.05) .No intraoperative complication occurred. There were two cases with incomplete adhesive intestinal obstruction at 15-20 days postoperatively, which one was in laparoscopic group and one was in gas-less laparoscopic group. At 6-50 months of following up (median time 12 months), all artificial vaginas had a capacity of over two fingers in wideness and 12-15 cm in length. Vaginal discharges resembled a milky white water or mucus without odour. Eighty-five patients with sexual intercourse reported satisfactory feeling. One patients complained vaginal stenosis in laparoscopic group. Gasless-laparoscopic vaginoplasty using sigmoid colon segment is an alternative feasible and practical treatment.

Laparoscopic surgery has become the treatment of choice for the management of perforated peptic ulcer. The advantages of laparoscopic repair for perforated peptic ulcer include less pain, a short hospital stay, and an early return to normal activity. Although the operation time of laparoscopic surgery is significantly longer than that of open surgery, laparoscopic technique is safe, feasible, and with morbidity and mortality comparable to that of the conventional open technique. To benefit from the advantages offered by minimally invasive laparoscopic technique, further study will need to determine whether laparoscopic surgery is safe in patients with generalized peritonitis or sepsis.

Since its introduction in the early 1990s, the laparoscopic cholecystectomy has become the standard surgical intervention for cholelithiasis. The laparoscopic technique is being used in an increasing number of abdominal procedures. Intestinal volvulus is a rare complication of laparoscopic procedures, such as the laparoscopic cholecystectomy. A review of the literature revealed 12 reports of this complication occurring without a clear cause. Etiologic factors that have been postulated include congenital malrotation, previous surgery, and intraoperative factors, such as pneumoperitoneum, mobilization of the bowel, and patient position. In this paper, we review the literature for this rare complication and report on a case of cecal bascule (a type of cecal volvulus) occurring following the laparoscopic cholecystectomy. Of the 12 prior reports of intestinal volvulus following laparoscopic procedures, 8 of these followed the laparoscopic cholecystectomy, of which two were cecal volvulae. This is the first reported case of a cecal bascule occurring following the laparoscopic cholecystectomy.

Complications within laparoscopic surgery, similar to classic surgery are inevitable and require immediate actions both to diminish intraoperative risks and to choose the appropriate therapeutic attitude. Peritonitis and hemorrhagic incidents are both part of the complications aspect of laparoscopic surgery. Fortunately, the incidence is limited, thus excluding the rejection of celioscopic methods. Patient's risks and benefits are to be analyzed carefully prior recommending laparoscopic surgery. This study presents a statistical analysis of peritonitis consecutive to laparoscopic surgery, experience of "Sf. Ioan" Emergency Hospital, Bucharest, and Department of Surgery (2000-2010). There were 180 (0,96%) complicated situations requiring reinterventions, from a total of 18676 laparoscopic procedures. 106 cases (0,56%) represented different grades of postoperative peritonitis. Most frequently, there were consecutive laparoscopic appendicectomia and colecistectomia. During the last decade, few severe cases of peritonitis followed laparoscopic bariatric surgical procedures. This study reflects the possibility of unfavorable evolution of postoperative peritonitis comparing with hemorrhagic incidents within laparoscopic surgery.

The aim of the study was to describe simultaneous laparoscopic adrenalectomy and laparoscopic nephron-sparing surgery, to discuss the details of a convenient laparoscopic approach and the way of port placement, as well as to present a review of the literature concerning combined laparoscopic procedures. A 72-year-old woman was admitted to our department because of a tumor of the right adrenal gland and a small tumor of the right kidney. The patient underwent simultaneous laparoscopic adrenalectomy and laparoscopic nephron-sparing surgery. The postoperative period was uncomplicated. The patient was discharged from the hospital on the 4th postoperative day. We believe that the proposed way of trocar placement would help to avoid a ‘rollover’ problem between the laparoscope and a Satinsky clamp or a ‘crossing swords’ problem between a Satinsky clamp and manipulators.

Open appendicectomy is the traditional standard treatment for appendicitis. Laparoscopic appendicectomy is perceived as a procedure with greater potential for complications and longer operative times. This paper examines the hypothesis that unsupervised laparoscopic appendicectomy by surgical trainees is a safe and time-effective valid alternative. Medical records, operating theatre records and histopathology reports of all patients undergoing laparoscopic and open appendicectomy over a 15-month period in two hospitals within an area health service were retrospectively reviewed. Data were analysed to compare patient features, pathology findings, operative times, complications, readmissions and mortality between laparoscopic and open groups and between unsupervised surgical trainee operators versus consultant surgeon operators. A total of 143 laparoscopic and 222 open appendicectomies were reviewed. Unsupervised trainees performed 64% of the laparoscopic appendicectomies and 55% of the open appendicectomies. There were no significant differences in complication rates, readmissions, mortality and length of stay between laparoscopic and open appendicectomy groups or between trainee and consultant surgeon operators. Conversion rates (laparoscopic to open approach) were similar for trainees and consultants. Unsupervised senior surgical trainees did not take significantly longer to perform laparoscopic appendicectomy when compared to unsupervised trainee-performed open appendicectomy. Unsupervised laparoscopic appendicectomy by surgical trainees is safe and time-effective.

Minimally invasive surgery has been replacing the open standard technique in several procedures. Similar or even better postoperative outcomes have been described in laparoscopic or robot-assisted procedures when compared to open surgery. Moreover, minimally invasive surgery has been providing less postoperative pain, shorter hospitalization, and thus a faster return to daily activities. However, the learning curve required to obtain laparoscopic expertise has been a barrier in laparoscopic spreading. Laparoscopic surgery training laboratory has been developed to aid surgeons to overcome the challenging learning curve. It may include tutorials, inanimate model skills training (box models and virtual reality simulators), animal laboratory, and operating room observation. Several different laparoscopic courses are available with specific characteristics and goals. Herein, we aim to describe the activities performed in a dry and animal-model training laboratory and to evaluate the impact of different kinds of laparoscopic surgery training courses on surgeon’s performance. Several tasks are performed in dry and animal laboratory to reproduce a real surgery. A short period of training can improve laparoscopic surgical skills, although most of times it is not enough to confer laparoscopic expertise for participants. Nevertheless, this short period of training is able to increase the laparoscopic practice of surgeons in their communities. Full laparoscopic training in medical residence or fellowship programs is the best way of stimulating laparoscopic dissemination. PMID:27933135

Laparoscopic surgery is increasingly replacing the open procedure because of its many patient-related benefits that are well aligned with policies and programs that seek to optimize health system performance. However, widespread adoption of laparoscopic surgery has been slow, in part, because of the complexity of laparoscopic suturing. The objective of this study was to review the clinical and economic impacts of laparoscopic suturing in key procedures and to assess its role as a barrier to the broader adoption of laparoscopic surgery. A medical literature search of MEDLINE, EMBASE, and BIOSIS from January 2010 through June 2016 identified 47 relevant articles. Laparoscopic suturing and intracorporeal knot tying may result in extended surgical time, complications, and surgeon errors, while improving patient quality of life through improved cosmesis, diet toleration, and better bowel movements. Despite advancement in surgical techniques and the availability of newer surgical tools, the complexity of laparoscopic suturing continues to be a barrier to greater adoption of MIS. The results of the study underscore the need for development of proficiency in laparoscopic suturing, which may help improve patient outcomes and reduce healthcare costs.

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.

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.

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.

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 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

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

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.

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.

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.

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)

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.

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

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

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.

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 is to show our experience with umbilical hernia herniorrhaphy and laparoscopic cholecystectomy, both in the same act. During last 10 years we operated 89 patients with cholecystitis and pre-existing umbilical hernia. In 61 of them we performed standard laparoscopic cholecystectomy and additional sutures of abdominal wall, and in 28 patients we performed in the same act laparoscopic cholecystectomy and herniorrhaphy of umbilical hernia. We observed incidence of postoperative herniation, and compared patients recovery after herniorrhaphy combined with laparoscopic cholecystectomy in the same act, and patients after standard laparoscopic cholecystectomy and additional sutures of abdominal wall. Patients, who had in the same time umbilical hernia herniorrhaphy and laparoscopic cholecystectomy, shown better postoperative recovery and lower incidence of postoperative umbilical hernias then patients with standard laparoscopic cholecystectomy and additional abdominal wall sutures.

Studies using conventional consoles have suggested a possible link between video-gaming and laparoscopic skill. The authors hypothesized that the Nintendo Wii, with its motion-sensing interface, would provide a better model for laparoscopic tasks. This study investigated the relationship between Nintendo Wii skill, prior gaming experience, and laparoscopic skill. In this study, 20 participants who had minimal experience with either laparoscopic surgery or Nintendo Wii performed three tasks on a Webcam-based laparoscopic simulator and were assessed on three games on the Wii. The participants completed a questionnaire assessing prior gaming experience. The score for each of the three Wii games correlated positively with the laparoscopic score (r = 0.78, 0.63, 0.77; P < 0.001), as did the combined Wii score (r = 0.82; P < 0.001). The participants in the top tertile of Wii performance scored 60.3% higher on the laparoscopic tasks than those in the bottom tertile (P < 0.01). Partial correlation analysis with control for the effect of prior gaming experience showed a significant positive correlation between the Wii score and the laparoscopic score (r = 0.713; P < 0.001). Prior gaming experience also correlated positively with the laparoscopic score (r = 0.578; P < 0.01), but no significant difference in the laparoscopic score was observed when the participants in the top tertile of experience were compared with those in the bottom tertile (P = 0.26). The study findings suggest a skill overlap between the Nintendo Wii and basic laparoscopic tasks. Surgical candidates with advanced Nintendo Wii ability may possess higher baseline laparoscopic ability.

Objective To evaluate the cost benefits of reusing disposable laparoscopic instruments. Design A cost-analysis study based on a review of laparoscopic and thoracoscopic procedures performed between August 1990 and January 1994, including analysis of disposable instrument use, purchase records, and reprocessing costs for each instrument. Setting The general surgery department of a 461-bed teaching hospital where disposable laparoscopic instruments are routinely reused according to internally validated reprocessing protocols. Methods Laparoscopic and thoracoscopic interventions performed between August 1990 and January 1994 for which the number and types of disposable laparoscopic instruments were standardized. Main Outcome Measures Reprocessing cost per instrument, the savings realized by reusing disposable laparoscopic instruments and the cost-efficient number of reuses per instrument. Results The cost of reprocessing instruments varied from $2.64 (Can) to $4.66 for each disposable laparoscopic instrument. Purchases of 10 commonly reused disposable laparoscopic instruments totalled $183 279, and the total reprocessing cost was estimated at $35 665 for the study period. Not reusing disposable instruments would have cost $527 575 in instrument purchases for the same period. Disposable laparoscopic instruments were reused 1.7 to 68 times each. Conclusions Under carefully monitored conditions and strict guidelines, reuse of disposable laparoscopic and thoracoscopic instruments can be cost-effective. PMID:8769924

Studies of in vitro fertilization (IVF) and sperm cryopreservation have been conducted in several small cat species, but virtually no data exist for black-footed cats (Felis nigripes) (BFCs) or sand cats (Felis margarita) (SCs). The objectives of this study were 1) to compare in vitro motility and acrosome status of fresh and cryopreserved (frozen in pellets on dry ice or in straws in liquid nitrogen vapor) BFC and SC spermatozoa cultured in feline-optimized culture medium (FOCM) or Ham F-10, 2) to assess ovarian responsiveness in BFCs and SCs following exogenous gonadotropin treatment and laparoscopic oocyte recovery, and 3) to evaluate the fertility of fresh and frozen-thawed spermatozoa from both species using homologous and heterologous (domestic cat oocytes) IVF in the two culture media. Motility and acrosomal integrity of fresh and frozen-thawed spermatozoa from BFCs and SCs were similar (P > 0.05) in both media during 6 h of culture. Although effects were more pronounced in SCs, cryopreservation in straws was superior (P < 0.05) to cryopreservation in pellets for both species. Gonadotropin stimulation produced approximately 16 ovarian follicles per female, and >80% of recovered oocytes were of optimal (grade 1) quality. The BFC and SC spermatozoa fertilized 60.0%-79.4% of homologous and 37.7%-42.7% of heterologous oocytes in both culture media, with increased (P < 0.05) cleavage of homologous (SC) and heterologous (BFC and SC) oocytes in FOCM. These results provide the first information to date on the gamete biology of two imperiled cat species and further our capacity to apply reproductive technologies for their conservation.

Place of laparoscopy in pelvic inflammatory disease.

577 laparoscopic examinations were performed in women presenting with sterility, chronic abdominal pain, primary or secondary amenorrhea, and irregular menstrual periods. 125 cases of chronic pelvic inflammatory disease (PID) of both the tuberculous and nonspecific varieties were detected through this procedure. 59 of the 125 cases were diagnosed as tuberculous. Investigations prior to laparoscopy had yielded significant results in only 12 cases. 87 of the 125 cases had no abnormal clinical findings, and only 18 of the 37 tubo-ovarian masses were diagnosed by bimanual examination. These results indicate that laparoscopy is an invaluable tool for the diagnosis of PID. It can reveal peritubal adhesions, tubercles on the tubes, small tubo-ovarian masses, and hydrosalpinx cases that cannot be detected clinically. It is considered a more suitable tool than culdoscopy, which less frequently notes adhesions to the fallopian tubes and pathological conditions in the upper pelvis. Laparoscopy can play an especially valuable role in India as a prelude to tuboplasty, given the high incidence of pelvic tuberculosis. Of the 316 cases of primary sterility examined in this study, 51 had genital tuberculosis and 39 had nonspecific PID. Laparoscopy can also be useful in disproving cases wrongly labelled as chronic pelvic disease. 15 women in this study who reported chronic lower abdominal pain had normal findings, and only 13 cases of PID were confirmed among the 33 cases preoperatively diagnosed as PID. A significant number of PID cases are attributed to operative procedures such as hysterosalpingography and ventrisuspension that are repeated unnecessarily and without proper sepsis. Thus, the possibility of a flare-up of infection during laparoscopy, especially due to hydroperturbation, should be considered. Women in this study who were found to have PID were given postoperative antibiotics. No significant postoperative complications were observed.

Polycystic ovary syndrome (PCOS) progression involves abnormal insulin signaling. SH2 domain-containing adaptor protein (Lnk) may be an important regulator of the insulin signaling pathway. We investigated whether Lnk was involved in insulin resistance (IR). Thirty-seven women due to receive laparoscopic surgery from June 2011 to February 2012 were included from the gynecologic department of the Sun Yat-Sen Memorial Hospital, Sun Yat-Sen University. Samples of polycystic and normal ovary tissues were examined by immunohistochemistry. Ovarian cell lines underwent insulin stimulation and Lnk overexpression. Expressed Lnk underwent coimmunoprecipitation tests with green fluorescent protein-labeled insulin receptor and His-tagged insulin receptor substrate 1 (IRS1), and their colocalization in HEK293T cells was examined. Ovarian tissues from PCOS patients with IR exhibited higher expression of Lnk than ovaries from normal control subjects and PCOS patients without IR; mainly in follicular granulosa cells, the follicular fluid and plasma of oocytes in secondary follicles, and atretic follicles. Lnk was coimmunoprecipitated with insulin receptor and IRS1. Lnk and insulin receptor/IRS1 locations overlapped around the nucleus. IR, protein kinase B (Akt), and ERK1/2 activities were inhibited by Lnk overexpression and inhibited further after insulin stimulation, whereas IRS1 serine activity was increased. Insulin receptor (Tyr1150/1151), Akt (Thr308), and ERK1/2 (Thr202/Tyr204) phosphorylation was decreased, whereas IRS1 (Ser307) phosphorylation was increased with Lnk overexpression. In conclusion, Lnk inhibits the phosphatidylinositol 3 kinase-AKT and MAPK-ERK signaling response to insulin. Higher expression of Lnk in PCOS suggests that Lnk probably plays a role in the development of IR.

Background Laparoscopic ovarian drilling (LOD) is an alternative method to induce ovulation in polycystic ovary syndrome (PCOS) patients with clomiphene citrate (CC) resistant instead of gonadotropins. This study aimed to compare the efficacy of unilateral LOD (ULOD) versus bilateral LOD (BLOD) in CC resistance PCOS patients in terms of ovulation and pregnancy rates. Materials and Methods In a prospective randomized clinical trial study, we included 100 PCOS patients with CC resistance attending to Al-Zahra Hospital in Rasht, Guilan Province, Iran, from June 2011 to July 2012. Patients were randomly divided into two ULOD and BLOD groups with equal numbers. The clinical and biochemical responses on ovulation and pregnancy rates were assessed over a 6-month follow-up period. Results Differences in baseline characteristics of patients between two groups prior to laparoscopy were not significant (p>0.05). There were no significant differences between the two groups in terms of clinical and biochemical responses, spontaneous menstruation (66.1 vs. 71.1%), spontaneous ovulation rate (60 vs. 64.4%), and pregnancy rate (33.1 vs. 40%) (p>0.05). Following drilling, there was a significant decrease in mean serum concentrations of luteinizing hormone (LH) (p=0.001) and testosterone (p=0.001) in both the groups. Mean decrease in serum LH (p=0.322) and testosterone concentrations (p=0.079) were not statistically significant between two groups. Mean serum level of follicle stimulating hormone (FSH) did not change significantly in two groups after LOD (p>0.05). Conclusion Based on results of this study, ULOD seems to be equally efficacious as BLOD in terms of ovulation and pregnancy rates (Registration Number: IRCT138903291306N2). PMID:25918587

Suprapubic and transvaginal pelvic ultrasound exploration is indicated for suspected ovarian tumor (standard). Diagnosis and search for extension require surgery and pathology examination. Systematic preoperative computed tomography is not recommended (standard). Surgery for cancer of the ovary is a specialized procedure requiring skill in cancer, gynecology, visceral surgery and laparoscopic surgery. If the patient is referred to a specialized center after a primary procedure considered to be inadequate, a new procedure is recommended for staging. Residual tumor volume after the primary procedure has prognostic value. Systematic second look procedures are not recommended for routine practice (standard). For patients with grade IA G1 tumors, there is no indication for complementary treatment (standard). For patients with grade IA G2-3 or clear cell tumors, IB, IC, IIA, there is no standard. no complementary treatment, complementary chemotherapy using platinum, complementary external abdominopelvic radiotherapy. A complementary treatment is recommended for grades IC and IIA. Complementary treatment for grades IIB (no residual tissue), IIC (with residual tissue), III (no residual tissue), is based on: complementary chemotherapy with platinium, complementary external abdominopelvic radiotherapy (options). Complementary treatment for advanced forms (IIB (with residual tissue), IIC (with residual tissue), III (with residual tissue) and IV) is based on polychemotherapy with platinium (standard). platinium combined with paclitaxel (intravenous), platinium combined with cyclophosphamide and/or doxorubicin (intravenous) or intraperitoneal cisplatin combined with cyclophosphamide (intravenous). The chemotherapy work-up includes physical examination, assay of serum markers (particularly CA125) and abdominopelvic computed tomography (proof level B) (standard).

To evaluate the prognostic impact of routinely use of staging laparoscopy (S-LPS) in patients with primary advanced epithelial ovarian cancer (AEOC). All women were submitted to S-LPS before receiving primary debulking surgery (PDS) or neoadjuvant treatment (NACT). The surgical and survival outcome were evaluated by univariate and multivariate analysis. Among 300 consecutive patients submitted to S-LPS no complications related to the surgical procedure were registered. The laparoscopic evaluation showed that almost half of the patients (46.3%) had a high tumor load. One-hundred forty-eight (49.3%) women were considered suitable for PDS and the remaining 152 (50.7%) were submitted to NACT. The percentages of complete (residual tumor, RT=0) and optimal (RT<1cm) cytoreduction of PDS and interval debulking surgery (IDS) were 62.1% and 57.5%, 22.5% and 27.7%, respectively, p=0.07. The post-operative complications of NACT/IDS group were lower than PDS group (p=0.01). The median progression free survival in women with RT=0 at PDS was 25 months (95% CI, 15.1-34.8), which was statistically significant longer than in all other patients, irrespective of the type of treatment they received (p=0.0001). At multivariate analysis, residual disease (p=0.011) and performance status (p=0.016) maintained an independent association with the PFS. Including S-LPS in a tertiary referral center for the management AEOC does not appear to have a negative impact in terms of survival and it may be helpful to individualize the treatment avoiding unnecessary laparotomies and surgical complications. © 2013.

Few studies investigated the efficacy and safety of minimally invasive surgery for the treatment of early-stage epithelial ovarian cancer (eEOC). In this context, we aimed to review the current evidence comparing laparoscopy and the laparotomic approach for staging procedures in eEOC. This systematic review was registered in the International Prospective Register of Systematic Reviews. Overall, 3065 patients were included: 1450 undergoing laparoscopy and 1615 undergoing laparotomic staging. Patients undergoing laparoscopy experienced a longer (but not statistically significant) operative time (weighted mean difference [WMD] = 28.3 minutes; 95% confidence interval [CI], -2.59 to 59.2), a lower estimated blood loss (WMD = -156.5 mL; 95% CI, -216.4 to -96.5), a shorter length of hospital stay (WMD = -3.7 days; 95% CI, -5.2 to -2.1), and a lower postoperative complication rate (odds ratio [OR] = 0.48; 95% CI, 0.29-0.81) than patients undergoing laparotomy. The upstaging (OR = 0.81; 95% CI, 0.55-1.20) and cyst rupture (OR = 1.32; 95% CI, 0.52-3.38) rates were similar between groups. Laparoscopic staging is associated with a shorter time to chemotherapy than laparotomic procedures (WMD = -5.16 days; 95% CI, -8.68 to -1.64). Survival outcomes were not influenced by the route of surgery. Pooled data suggested that the minimally invasive surgical approach is equivalent to laparotomy for the treatment of eEOC and may be superior in terms of perioperative outcomes. However, because of the low level of evidence of the included studies, further randomized trials are warranted. Copyright © 2017 AAGL. Published by Elsevier Inc. All rights reserved.

This prospective study describes a simple method of combining laparoscopic ovariectomy and laparoscopic-assisted prophylactic gastropexy and determines the duration of surgery, complications, and long-term outcome including prevention of gastric dilatation-volvulus (GDV). Laparoscopic ovariectomy and laparoscopic-assisted gastropexy were performed on 26 sexually intact female dogs susceptible to GDV. The mean surgery time was 60.8 ± 12.4 min. No GDV episode was seen during the study period (mean follow-up: 5.2 ± 1.4 y). All dogs had an intact gastropexy attachment assessed by ultrasonography at 1 y. Post-operative complications were minor and owners were satisfied with the procedure. Combined laparoscopic ovariectomy and laparoscopic- assisted gastropexy appears to be a successful and low morbidity alternative procedure to both ovariectomy/ovariohysterectomy and gastropexy via open ventral-midline laparotomy.

The biomechanical and mental strains placed on the surgeon while performing laparoscopic procedures are significantly higher compared with open surgical techniques. We undertook this study to assess the prevalence of surgeons' deleterious perceptions or injuries related to laparoscopic urologic surgery. Members of endourological society were mailed a questionnaire evaluating their laparoscopic experience, total number of standard laparoscopic surgeries (SLS), hand-assisted laparoscopic surgeries (HALS), and robotic-assisted laparoscopic surgeries (RALS) they performed. The subjects reported any neuromuscular or arthritic injuries sustained during laparoscopic surgery, and graded the degree of pain, numbness, and fatigue they experienced. A total of 73 urologists completed the questionnaires. The average responder was 44 years old, had completed a median of 117 procedures, and was performing 3 laparoscopic surgeries per week. Neuromuscular or arthritic symptoms during surgery were reported by 22 responders (30%), the most common was finger paresthesia (18%). At the conclusion of HALS, 45% of the surgeons suffered from hand and wrist numbness and 37% reported pain in these areas. A significant association was observed between the risk of sustaining injury during surgery and the total number of laparoscopic procedures performed by the responder (P = 0.016). RALS was the procedure least associated with injuries, and HALS the most. The laparoscopic operating theater is a hostile ergonomic environment. Surgeons' awareness of the common injuries associated with laparoscopic surgery and careful equipment adjustments before surgery are mandatory to minimize injury. Future improvements in instrument design according to ergonomic principles are highly warranted.

The objective of this study was to evaluate patients who underwent laparoscopic Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy in terms of weight loss, metabolic parameters, and postoperative complications. Data on patients who underwent laparoscopic Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy with a diagnosis of morbid obesity between January 2012 and June 2014 were retrospectively evaluated. Patients were compared in terms of age, sex, body mass index, duration of operation, American Society of Anesthesiologists score, perioperative complications, length of hospital stay, and long term follow-up results. During the study period, 91 patients (45 laparoscopic Roux-en-Y gastric bypass and 46 laparoscopic sleeve gastrectomy) underwent bariatric surgery. There was no difference between the two groups in terms of preoperative patient characteristics. Both groups showed statistically significant weight loss and improvement in co-morbidities when compared with the preoperative period. Weight loss and improvement in metabolic parameters were similar in both groups. The duration of operation and hospital stay was longer in the laparoscopic Roux-en-Y gastric bypass group. Furthermore, the rate of total complications was significantly lower in the laparoscopic sleeve gastrectomy group. Laparoscopic sleeve gastrectomy is a safe and effective method with a significantly lower complication rate and length of hospital stay than laparoscopic Roux-en-Y gastric bypass, with similar improvement rates in metabolic syndrome.

Ghosh, Sudip; Niklewski, Paul; Roy, Sanjoy

2017-01-01

Background: Laparoscopic surgery is increasingly replacing the open procedure because of its many patient-related benefits that are well aligned with policies and programs that seek to optimize health system performance. However, widespread adoption of laparoscopic surgery has been slow, in part, because of the complexity of laparoscopic suturing. The objective of this study was to review the clinical and economic impacts of laparoscopic suturing in key procedures and to assess its role as a barrier to the broader adoption of laparoscopic surgery. Database: A medical literature search of MEDLINE, EMBASE, and BIOSIS from January 2010 through June 2016 identified 47 relevant articles. Conclusion: Laparoscopic suturing and intracorporeal knot tying may result in extended surgical time, complications, and surgeon errors, while improving patient quality of life through improved cosmesis, diet toleration, and better bowel movements. Despite advancement in surgical techniques and the availability of newer surgical tools, the complexity of laparoscopic suturing continues to be a barrier to greater adoption of MIS. The results of the study underscore the need for development of proficiency in laparoscopic suturing, which may help improve patient outcomes and reduce healthcare costs. PMID:28694682

The surgeons of the future will need to have advanced laparoscopic skills. The current challenge in surgical education is to teach these skills and to identify factors that may have a positive influence on training curriculums. The primary aim of this study was to determine if fundamental aptitude impacts on ability to perform a laparoscopic colectomy. A practical laparoscopic colectomy course was held by the National Surgical Training Centre at the Royal College of Surgeons in Ireland. The course consisted of didactics, warm-up and the performance of a laparoscopic sigmoid colectomy on thesimulator. Objective metrics such as time and motion analysis were recorded. Each candidate had their psychomotor and visual spatial aptitude assessed. The colectomy trays were assessed by blinded experts post procedure for errors. Ten trainee surgeons that were novices with respect to advanced laparoscopic procedures attended the course. A significant correlation was found between psychomotor and visual spatial aptitude and performance on both the warm-up session and laparoscopic colectomy (r > 0.7, p < 0.05). Performance on the warm-up session correlated with performance of the laparoscopic colectomy (r = 0.8, p = 0.04). There was also a significant correlation between the number of tray errors and time taken to perform the laparoscopic colectomy (r = 0.83, p = 0.001). The results have demonstrated that there is a relationship between aptitude and ability to perform both basic laparoscopic tasks and laparoscopic colectomy on a simulator. The findings suggest that there may be a role for the consideration of an individual's inherent baseline ability when trying to design and optimise technical teaching curricula for advanced laparoscopic procedures.

Clomiphene citrate alternatives for the initial management of polycystic ovary syndrome: an evidence-based approach.

2012-06-01

Polycystic ovary syndrome (PCOS) is a prevalent and heterogeneous condition affecting 4-8% of reproductive age women. It is the most common cause of chronic anovulation and is associated with hyperandrogenemia. Clomiphene citrate (CC) is considered as the first-line therapy for ovulation induction in these patients. Despite progress in understanding the pathophysiology of PCOS over the past 20 years, many questions persist to the extent that PCOS was described as "A Riddle Wrapped in a Mystery inside an Enigma". On the other hand, a recent publication from the Centers for Disease Control suggested that CC may be associated with an increased risk of birth defects. The purpose of this review is to critically evaluate and summarize the current literature regarding CC alternatives for the initial management of PCOS focusing specifically on the roles of weight loss and other approaches to ovulation induction as insulin-sensitizing drugs, aromatase inhibitors, minimal stimulation protocol, gonadotrophins and surgery (laparoscopic ovarian drilling). Finally, the efficacy of intrauterine insemination with CC for the initial management of PCOS will be evaluated.

A case of idiopathic intracranial hypertension associated with PCOS.

Idiopathic intracranial hypertension (IIH) is a rare neurologic disorder. It is also known as pseudotumor cerebri. The incidence of IIH is one to two per 100,000 population annually. The higher incidence is in obese women from 15 to 44 years. The main symptoms are headache and visual loss. It mostly affects women of childbearing age who are overweight or obese. There are many theories of pathogenesis of IIH, but precise pathogenesis is unknown. One of the causes of IIH is intracranial venous sinus thrombosis. It can cause increased cerebrospinal fluid (CSF) pressure by obstruction of venous outflow and blocking of CSF absorption. In polycystic ovary syndrome (PCOS) patients, thrombogenic tendency is increased due to increased aromatization of testosterone to estradiol which could induce estrogen-mediated thrombophilia. The authors present a 14-year-old girl with PCOS stigma who presented with a severe headache and papilledema. These symptoms were not improved by standard medical therapy of IIH and PCOS, but improved after laparoscopic ovarian drilling. The authors report it with a review of the literature.

Robotic platforms have the potential advantage of providing additional dexterity and precision to surgeons while performing complex laparoscopic tasks, especially for those in training. Few quantitative evaluations of surgical task performance comparing laparoscopic and robotic platforms among surgeons of varying experience levels have been done. We compared measures of quality and efficiency of Fundamentals of Laparoscopic Surgery task performance on these platforms in novices and experienced laparoscopic and robotic surgeons. Fourteen novices, 12 expert laparoscopic surgeons (>100 laparoscopic procedures performed, no robotics experience), and five expert robotic surgeons (>25 robotic procedures performed) performed three Fundamentals of Laparoscopic Surgery tasks on both laparoscopic and robotic platforms: peg transfer (PT), pattern cutting (PC), and intracorporeal suturing. All tasks were repeated three times by each subject on each platform in a randomized order. Mean completion times and mean errors per trial (EPT) were calculated for each task on both platforms. Results were compared using Student's t-test (P < 0.05 considered statistically significant). Among novices, greater errors were noted during laparoscopic PC (Lap 2.21 versus Robot 0.88 EPT, P < 0.001). Among expert laparoscopists, greater errors were noted during laparoscopic PT compared with robotic (PT: Lap 0.14 versus Robot 0.00 EPT, P = 0.04). Among expert robotic surgeons, greater errors were noted during laparoscopic PC compared with robotic (Lap 0.80 versus Robot 0.13 EPT, P = 0.02). Among expert laparoscopists, task performance was slower on the robotic platform compared with laparoscopy. In comparisons of expert laparoscopists performing tasks on the laparoscopic platform and expert robotic surgeons performing tasks on the robotic platform, expert robotic surgeons demonstrated fewer errors during the PC task (P = 0.009). Robotic assistance provided a reduction in errors at all experience levels for some laparoscopic tasks, but no benefit in the speed of task performance. Robotic assistance may provide some benefit in precision of surgical task performance. Copyright © 2017 Elsevier Inc. All rights reserved.

Communication is important for patient safety in the operating room (OR). Several studies have assessed OR communications qualitatively or have focused on communication in crisis situations. This study used prospective, quantitative observation based on well-established communication theory to assess similarities and differences in communication patterns between open and laparoscopic surgery. Based on communication theory, a standardized proforma was developed for assessment in the OR via real-time observation of communication types, their purpose, their content, and their initiators/recipients. Data were collected prospectively in real time in the OR for 20 open and 20 laparoscopic inguinal hernia repairs. Assessors were trained and calibrated, and their reliability was established statistically. During 1,884 min of operative time, 4,227 communications were observed and analyzed (2,043 laparoscopic vs 2,184 open communications). The mean operative duration (laparoscopic, 48 min vs open, 47 min), mean communication frequency (laparoscopic, 102 communications/procedure vs open, 109 communications/procedure), and mean communication rate (laparoscopic, 2.13 communications/min vs open, 2.23 communications/min) did not differ significantly across laparoscopic and open procedures. Communications were most likely to be initiated by surgeons (80-81 %), to be received by either other surgeons (46-50%) or OR nurses (38-40 %), to be associated with equipment/procedural issues (39-47 %), and to provide direction for the OR team (38-46%) in open and laparoscopic cases. Moreover, communications in laparoscopic cases were significantly more equipment related (laparoscopic, 47 % vs open, 39 %) and aimed significantly more at providing direction (laparoscopic, 46 % vs open, 38 %) and at consulting (laparoscopic, 17 % vs open, 12 %) than at sharing information (laparoscopic, 17 % vs open, 31 %) (P < 0.001 for all). Numerous intraoperative communications were found in both laparoscopic and open cases during a relatively low-risk procedure (average, 2 communications/min). In the observed cases, surgeons actively directed and led OR teams in the intraoperative phase. The lack of communication between surgeons and anesthesiologists ought to be evaluated further. Simple, inexpensive interventions shown to streamline intraoperative communication and teamworking (preoperative briefing, surgeons' mental practice) should be considered further.

It has been acknowledged that standardised training programmes are needed to improve laparoscopic training of urologic trainees. Previous studies have suggested that simulator-based laparoscopic training can improve performance during real laparoscopic procedures. To determine if there are performance differences for the completion of a simulated laparoscopic suturing task among urology residents based on their postgraduate year of training (PGY). Using a validated scoring checklist, two independent observers objectively scored the completion of a standardised laparoscopic suturing task in a bench-top laparoscopic box trainer. PGY and previous exposure to laparoscopic surgery and laparoscopic simulated training was obtained from self-administered questionnaires. Data acquisition was undertaken at the European Urological Residents Education Programme (EUREP) 2007, run by the European School of Urology, and included a pan-European cohort of 201 urology residents. Reliability among those rating the suturing tasks was excellent (Cronbach's α=0.83). Each resident was scored for the suturing task. Residents were categorised into three groups based on their PGY status (junior [n=8]; intermediate [n=37]; senior [n=156]). The Kruskal-Wallis test was used to measure trend across the PGY; the Mann-Whitney U test was used to determine variation among categorised PGY groups. Laparoscopic suturing skill was significantly different across PGY levels (p=0.032), and between junior residents and both intermediate and senior residents (p=0.008 and p=0.012, respectively). There was no significant difference between intermediate and senior residents (p=0.697). Only 12% of participants rated their existing volume of laparoscopic operative cases as sufficient, while 55% of participants had no regular opportunities, and 32% of participants had not performed laparoscopic procedures as primary surgeon. Most residents (96%) reported the use of laparoscopic simulators to be beneficial in training, although current European training programmes appear to provide <50% of residents with the opportunity to train with them. A discernable relationship existed between the score obtained for a laparoscopic suturing task and year of resident training. Modular simulator training as part of a formal training programme may help to overcome some of the shortfall in residents' exposure to laparoscopic procedures as primary surgeon.

Content, evaluation, and certification of laparoscopic skills and procedure training lack uniformity among different hospitals in The Netherlands. Within the process of developing a new regional laparoscopic training curriculum, a uniform and transferrable curriculum was constructed for a series of laparoscopic procedures. The aim of this study was to determine regional expert consensus regarding the key steps for laparoscopic appendectomy and cholecystectomy using Delphi methodology. Lists of suggested key steps for laparoscopic appendectomy and cholecystectomy were created using surgical textbooks, available guidelines, and local practice. A total of 22 experts, working for teaching hospitals throughout the region, were asked to rate the suggested key steps for both procedures on a Likert scale from 1-5. Consensus was reached with Crohnbach's α ≥ 0.90. Of the 22 experts, 21 completed and returned the survey (95%). Data analysis already showed consensus after the first round of Delphi on the key steps for laparoscopic appendectomy (Crohnbach's α = 0.92) and laparoscopic cholecystectomy (Crohnbach's α = 0.90). After the second round, 15 proposed key steps for laparoscopic appendectomy and 30 proposed key steps for laparoscopic cholecystectomy were rated as important (≥4 by at least 80% of the expert panel). These key steps were used for the further development of the training curriculum. By using the Delphi methodology, regional consensus was reached on the key steps for laparoscopic appendectomy and cholecystectomy. These key steps are going to be used for standardized training and evaluation purposes in a new regional laparoscopic curriculum. Copyright © 2014 Association of Program Directors in Surgery.

The costs to perform a hysterectomy are widely variable. Our objective was to determine hysterectomy costs by route and whether traditionally open surgeons lower costs when performing laparoscopy versus robotics. Hysterectomy costs including subcategories were collected from 2011 to 2013. Costs were skewed, so 2 statistical transformations were performed. Costs were compared by surgeon classification (open, laparoscopic, or robotic) and surgery route. A total of 4,871 hysterectomies were performed: 34.2% open, 50.7% laparoscopic, and 15.1% robotic. Laparoscopic hysterectomy had the lowest total costs (P < .001). By cost subcategory, laparoscopic hysterectomy was lower than robotic hysterectomy in 6 and higher in 1. When performing robotic hysterectomy, open and robotic surgeon costs were similar. With laparoscopic hysterectomy, open surgeons had higher costs than laparoscopic surgeons for 1 of 2 statistical transformations (P = .007). Open surgeons had lower costs performing laparoscopic hysterectomy than robotic hysterectomy with robotic maintenance and depreciation included (P < .001) but similar costs if these variables were excluded. Although laparoscopic hysterectomy had lowest costs overall, robotics may be no more costly than laparoscopic hysterectomy when performed by surgeons who predominantly perform open hysterectomy.

Laparoscopic subtotal colectomy (STC) is a complex procedure. It is possible that short-term benefits for segmental resections cannot be attributed to this complex procedure. This study aims to assess differences in short-term results for laparoscopic versus open STC during a 15-year single-institute experience. We reviewed consecutive patients undergoing laparoscopic or open elective or subacute STC from January 1997 to December 2012. Fifty-six laparoscopic and 50 open STCs were performed. The operation time was significantly longer in the laparoscopic group, median 266 min (range 121-420 min), compared to 153 min (range 90-408 min) in the open group (p < 0.001). Median hospital stay showed no statistical difference, 14 days (range 1-129 days) in the laparoscopic and 13 days (range 1-85 days) in the open group. Between-group postoperative complications were not statistically different. Laparoscopic STC has short-term results similar to the open procedure, except for a longer operation time. The laparoscopic approach for STC is therefore only advisable in selected patients combined with extensive preoperative counseling. Copyright © 2013 S. Karger AG, Basel.

To analyse the outcomes of laparoscopic versus open repair for perforated peptic ulcers (PPU). All patients undergoing PPU repair between January 2002 and March 2012 were included in the study. Demographic characteristics, operation time, complications, and length of hospital stay were evaluated. Two hundred and twelve patients (median age, 49 years) were included, 60 in the laparoscopic group and 52 in the open group. Patients operated laparoscopically were significantly younger and had a higher consumption of tobacco, alcohol and cannabis. Median acute symptoms time was shorter in the laparoscopic group (6h) compared to the open group (12h; P=.025) Symptoms time was shorter in the laparoscopic group. Median operating time was significantly longer in the laparoscopic group (104.5min vs. 76min, P=.025). The percentage of conversion to open repair was 25%. There was no difference in morbidity between 2 groups, but there were 3 deaths in the open group. Median hospital stay was significantly shorter in patients treated laparoscopically when compared with the open group (6 days vs. 8 days; P=.041). Laparoscopic and open repair are equally safe in the management of PPU. A shorter hospital stay can be achieved in the laparoscopic group. Copyright © 2012 AEC. Published by Elsevier Espana.

The aim of this study was to compare the effectiveness and long-term anatomic and functional results of laparoscopic peritoneal vaginoplasty and laparoscopic sigmoid vaginoplasty. From January 2002 to December 2010, 40 patients with congenital vaginal agenesis were prospectively randomized to undergo either laparoscopic peritoneal vaginoplasty (26 cases) or laparoscopic sigmoid vaginoplasty (14 cases) in 2:1 ratio. Pre- and postoperative examination findings, Female Sexual Function Index (FSFI) questionnaire responses, and sexual satisfaction rates are reported. All surgical procedures were performed successfully, with no intraoperative complications. The laparoscopic peritoneal vaginoplasty group had significantly less blood loss and a surgery shorter on average than the laparoscopic sigmoid colovaginoplasty group. Postoperative course was uneventful for all patients in both groups, though postoperative retention time and hospital stay were less for peritoneal vaginoplasty patients than for sigmoid vaginoplasty patients. Mean neovaginal length, excessive mucous production, sexual life initiation time, and sexual satisfaction rate were similar between groups. Patient complaints of abdominal discomfort, unusual odor from vaginal secretions, and vaginal contraction during intercourse were higher in the sigmoid colovaginoplasty group (p < 0.005 vs. peritoneal vaginoplasty). Postoperative FSFI scores did not differ significantly between groups. Relative to laparoscopic sigmoid colovaginoplasty, laparoscopic peritoneal vaginoplasty provides good anatomic and functional results and excellent patient satisfaction.

The use of laparoscopic surgery has been well established for the management of abdominal emergencies. However, the value of this technique for postoperative hemorrhage in urology has not been characterized. We present our favorable experience with laparoscopic exploration after urologic surgery and suggest guidelines for laparoscopic management of post-laparoscopy bleeding. Three patients who developed hemorrhage shortly after laparoscopic urologic surgery and were managed by laparoscopic exploration were identified from a series of 910 laparoscopic urologic procedures performed at our institution from October 2002 to June 2006. Three patients, who were hemodynamically stable (two after robot-assisted laparoscopic prostatectomy, one after laparoscopic radical nephrectomy), required prompt surgical exploration for postoperative hemorrhage not stabilized by blood transfusion (mean 2.7 units) at a mean of 19.4 hours after initial surgery. Clots were evacuated with a 10-mm suction-irrigator. Two patients were found to have abdominal-wall arterial bleeding and were managed with suture ligation. The third patient demonstrated diffuse bleeding from the prostatic bed, which was controlled with Surgicel and FloSeal. Bleeding was efficiently controlled in all patients, and none required post-exploration transfusion. The mean post-exploration hospital stay was 2.3 days. Significant hemorrhage after urologic laparoscopy is a rare event. We found laparoscopic exploration to be an excellent way to diagnose and correct such hemorrhage in certain patients. Early diagnosis with clinical and hematologic studies, a lowered threshold for surgical exploration, and specific operative equipment may decrease patient morbidity and the need for open surgical exploration.

A small number of patients fail fundoplication and require reoperation. Laparoscopic techniques have been applied to reoperative fundoplications. We reviewed our experience with reoperative laparoscopic fundoplication. Reoperative laparoscopic fundoplication was undertaken in 28 patients, 19 F and 9 M, of mean age 56 years +/- 12. Previous antireflux procedures included 19 open and 12 laparoscopic antireflux operations. Symptoms were heartburn (90%), dysphagia (35%), and atypical symptoms (30%%). The mean interval from antireflux procedure to revision was 13 months +/- 4.2. The mean DeMeester score was 78+/-32 (normal 14.7). Eighteen patients (64%) had hiatal breakdown, 17 (60%) had wrap failure, 2 (7%) had slipped Nissen, 3 (11%) had paraesophageal hernias, and 1 (3%) had an excessively tight wrap. Twenty-five revisions were completed laparoscopically, while 3 patients required conversion to the open technique. Complications occurred in 9 of 17 (53%) patients failing previous open fundoplications and in 4 of 12 patients (33%) failing previous laparoscopic fundoplications and included 15 gastrotomies and 1 esophagotomy, all repaired laparoscopically, 3 postoperative gastric leaks, and 4 pneumothoraces requiring tube thoracostomy. No deaths occurred. Median length of stay was 5 days (range 2-90 days). At a mean follow-up of 20 months +/- 17, 2 patients (7%) have failed revision of their fundoplications, with the rest of the patients being essentially asymptomatic (93%). The results achieved with reoperative laparoscopic fundoplication are similar to those of primary laparoscopic fundoplications. Laparoscopic reoperations, particularly of primary open fundoplication, can be technically challenging and fraught with complications. Copyright 2001 Academic Press.

Video games are mainly considered to be of entertainment value in our society. Laparoscopic surgery and video games are activities similarly requiring eye-hand and visual-spatial skills. Previous studies have not conclusively shown a positive correlation between video game experience and improved ability to accomplish visual-spatial tasks in laparoscopic surgery. This study was an attempt to investigate this relationship. The aim of the study was to investigate whether previous video gaming experience affects the baseline performance on a laparoscopic simulator trainer. Newly qualified medical officers with minimal experience in laparoscopic surgery were invited to participate in the study and assigned to the following groups: gamers (n = 20) and non-gamers (n = 20). Analysis included participants' demographic data and baseline video gaming experience. Laparoscopic skills were assessed using a laparoscopic simulator trainer. There were no significant demographic differences between the two groups. Each participant performed three laparoscopic tasks and mean scores between the two groups were compared. The gamer group had statistically significant better results in maintaining the laparoscopic camera horizon ± 15° (p value = 0.009), in the complex ball manipulation accuracy rates (p value = 0.024) and completed the complex laparoscopic simulator task in a significantly shorter time period (p value = 0.001). Although prior video gaming experience correlated with better results, there were no significant differences for camera accuracy rates (p value = 0.074) and in a two-handed laparoscopic exercise task accuracy rates (p value = 0.092). The results show that previous video-gaming experience improved the baseline performance in laparoscopic simulator skills. Copyright © 2017 IJS Publishing Group Ltd. Published by Elsevier Ltd.

Laparoscopic sleeve gastrectomy is gaining popularity in the US; however, there has been no study examining the use of sleeve gastrectomy at a national level and its impact on the use of other bariatric operations. The aim of this study was to examine contemporary changes in use and outcomes of bariatric surgery performed at academic medical centers. Using ICD-9 diagnosis and procedure codes, clinical data obtained from the University HealthSystem Consortium database for all bariatric procedures performed for the treatment of morbid obesity between October 1, 2008 and September 30, 2012 were reviewed. Quartile trends in use for the 3 most commonly performed bariatric operations were examined, and a comparison of perioperative outcomes between procedures was performed within a subset of patients with minor severity of illness. A total of 60,738 bariatric procedures were examined. In 2008, the makeup of bariatric surgery consisted primarily of gastric bypass (66.8% laparoscopic, 8.6% open), followed by laparoscopic gastric banding (23.8%). In 2012, there was a precipitous increase in use of laparoscopic sleeve gastrectomy (36.3 %), with a concurrent reduction in the use of laparoscopic (56.4%) and open (3.2%) gastric bypass, and a major reduction in laparoscopic gastric banding (4.1%). The length of hospital stay, in-hospital morbidity and mortality, and costs for laparoscopic sleeve gastrectomy were found to be between those of laparoscopic gastric banding and laparoscopic gastric bypass. Within the context of academic medical centers, there has been a recent change in the makeup of bariatric surgery. There has been an increase in the use of laparoscopic sleeve gastrectomy, which has had an impact primarily on reducing the use of laparoscopic adjustable gastric banding.

Population-based studies evaluating laparoscopic colectomy and outcomes compared with open surgery have concentrated on elective resections. As such, data assessing non-elective laparoscopic colectomies are limited. Our goal was to evaluate the current usage and outcomes of laparoscopic in the urgent and emergent setting in the USA. A national inpatient database was reviewed from 2008 to 2011 for right, left, and sigmoid colectomies in the non-elective setting. Cases were stratified by approach into open or laparoscopic groups. Demographics, perioperative clinical variables, and financial outcomes were compared across each group. A total of 22,719 non-elective colectomies were analyzed. The vast majority (95.8 %) was open. Most cases were performed in an urban setting at non-teaching hospitals by general surgeons. Colorectal surgeons were significantly more likely to perform a case laparoscopic than general surgeons (p < 0.001). Demographics were similar between open and laparoscopic groups; however, the disease distribution by approach varied, with significantly more severe cases in the open colectomy arm (p < 0.001). Cases performed laparoscopically had significantly better mortality and complication rates. Laparoscopic cases also had significantly improved outcomes, including shorter length of stay and hospital costs (all p < 0.001). Our analysis revealed less than 5 % of urgent and emergent colectomies in the USA are performed laparoscopically. Colorectal surgeons were more likely to approach a case laparoscopically than general surgeons. Outcomes following laparoscopic colectomy in this setting resulted in reduced length of stay, lower complication rates, and lower costs. Increased adoption of laparoscopy in the non-elective setting should be considered.

2015-01-01

BACKGROUND Compared to standard laparoscopy, single-site laparoscopic colorectal surgerymay potentially offer advantages by creating fewer surgical incisions and providing a multi-functional trocar. Previous comparisons, however, have been limited by small sample sizes and selection bias. OBJECTIVE To compare 60-day outcomes between standard laparoscopic and single-site laparoscopic colorectal surgery patients undergoing elective and urgent surgeries. DESIGN This was an unselected retrospective cohort study comparing patients who underwent elective and unplanned standard laparoscopic or single-site laparoscopic colorectal resections for benign and malignant disease between 2008 and 2014. Outcomes were compared using univariate analyses. SETTING This study was conducted at a single institution. PATIENTS A total of 626 consecutive patients undergoing laparoscopic colorectal surgery were included. MAIN OUTCOME MEASURES Morbidity and mortality within 60 postoperative days. RESULTS 318 (51%) and 308 (49%) patients underwent standard laparoscopic and single-site laparoscopic procedures, respectively. No significant difference was noted in mean operative time (Standard laparoscopy 182.1 ± 81.3 vs. Single-site laparoscopy 177±86.5, p=0.30) and postoperative length of stay (Standard laparoscopy 4.8±3.4 vs. Single-site laparoscopy 5.5 ± 6.9, p=0.14). Conversions to laparotomy and 60-day readmissions were also similar for both cohorts across all procedures performed. A significant difference was identified in the number of patients who developed postoperative complications (Standard laparoscopy 19.2% vs. Single-site laparoscopy 10.7%, p=0.004), especially with respect to surgical-site infections (Standard laparoscopy 11.3% vs. Single-site laparoscopy 5.8%, p=0.02). LIMITATIONS This was a retrospective, single institution study. CONCLUSIONS Single-site laparoscopic colorectal surgery demonstrates similar results to standard laparoscopic colorectal surgery in regards to operative time, length of stay and readmissions. Single-site laparoscopic colorectal surgery may provide advantages in limiting the development of certain complications such as superficial surgical-site infections. PMID:26252848

Concern has been voiced that general surgery residents who train at institutions that also offer advanced laparoscopic fellowships may receive inadequate advanced laparoscopic operative experience. The purpose of our study was to compare the operative experience of general surgery residents who graduated from our institution before initiation of an advanced laparoscopic fellowship with the experience of those who graduated after the fellowship began. Operative case logs of surgery residents who graduated from 2000 through 2007 and of advanced laparoscopic fellows from 2004 through 2007 were reviewed. Surgery resident experience with basic and nonbariatric advanced laparoscopic cases during the 4 years before the fellowship was compared with the experience during the 4 years after the fellowship began. Residents who graduated before 2004 performed a mean of 140.5 +/- 19.4 basic and 77.0 +/- 17.8 advanced laparoscopic cases during their 5-year residency, compared with 193.3 +/- 34.5 basic (p = 0.003) and 113.3 +/- 23.5 advanced cases (p = 0.005) performed by those who graduated in 2004 or later. The number of nonbariatric advanced laparoscopic cases performed by each graduating surgical resident during the chief year ranged from 26 to 47 cases from 2000 to 2003 and from 36 to 69 cases from 2004 to 2007. Fellows reported from 40 to 85 nonbariatric advanced laparoscopic cases annually. General surgery residents did not experience a reduction in the total number of basic and nonbariatric advanced laparoscopic cases with the addition of an advanced laparoscopic fellowship, nor did they perform fewer cases during the chief year. As the result of a cooperative venture between the surgery residency and fellowship directors as well as an expansion of the total number of laparoscopic cases performed at our institution because of changes in clinical practice, surgery residents reported an increase in the number of laparoscopic cases while a successful fellowship was established.

Controlled multicenter trial of laparoscopic transabdominal preperitoneal hernioplasty vs Shouldice herniorrhaphy. Early results.

In February 1993 a prospective randomized multicenter trial was initiated to compare laparoscopic transabdominal preperitoneal hernioplasty to Shouldice herniorrhaphy as performed by surgeons of nonspecialized clinics. Until January 1994, 87 patients with 108 hernias took part in the trial (43 Shouldice and 44 laparoscopic repairs). The laparoscopic procedure took significantly longer than did the open operation but caused less pain as measured by pain analogue score and consumption of paracetamol and narcotics. The postoperative complication rate was 26% in the open and 16% in the laparoscopic group. The patients in the laparoscopic group were discharged earlier and their convalescence was shorter than after open hernia repair. There has been one early recurrence in the laparoscopic and two in the open group to date with a mean follow-up of 201 days. Laparoscopic hernia repair causes less pain than the conventional operation and enables the patient to return to full work and usual activities earlier. The recurrence rate will not be known for 5 years.

Virtual reality simulation has a great potential as a training and assessment tool of laparoscopic skills. The study was carried out to investigate whether the LapSim system (Surgical Science Ltd., Gothenburg, Sweden) was able to differentiate between subjects with different laparoscopic experience and thus to demonstrate its construct validity. Subjects 24 were divided into two groups: experienced (performed > 100 laparoscopic procedures, n = 10) and beginners (performed <10 laparoscopic procedures, n = 14). Assessment of laparoscopic skills was based on parameters measured by the computer system. Experienced surgeons performed consistently better than the residents. Significant differences in the parameters time and economy of motion existed between the two groups in seven of seven tasks. Regarding error parameters, differences existed in most but not all tasks. LapSim was able to differentiate between subjects with different laparoscopic experience. This indicates that the system measures skills relevant for laparoscopic surgery and can be used in training programs as a valid assessment tool.

Telemedicine is the use of electronic digital signals to transfer information from one site to another. With the advent of a telepresence operative system and development of remote robotic arms to hold and manoeuvre the laparoscope, telemedicine is finding its role in surgery, especially laparoscopic surgery. CLINICAL FEATURES AND TREATMENT: We report two successful cases of laparoscopic surgery--radical nephrectomy and varicocelectomy for a 3-cm renal tumour and for bilateral varicoceles causing pain, where a less experienced laparoscopic surgeon in Singapore was telementored by an experienced laparoscopic surgeon located remotely in the United States. Both patients recovered uneventfully and returned home on postoperative day 4 and on the day of surgery, respectively. This study demonstrates that telementored laparoscopic systems are feasible and safe, between countries halfway across the world. As the Internet expands in utility and the cost of higher bandwidth telecommunication lines decreases, even to remote countries, telementoring systems will become more affordable and may potentially pave the way for advanced surgical and laparoscopic applications and training for the future.

Laparoscopic splenectomy is a well described gold standard procedure for various indications. One of the key steps during laparoscopic splenectomy is the hilar pedicle vessels control, which can be challenging in most cases. Most centres around the world recommend the use Ligaclib or endovascular staplers as Methods of choice for hilar pedicle control but the issue is the cost and efficiency of the laparoscopic haemostatic devices. A descriptive retrospective study of patients who had laparoscopic splenectomy from 2013 to present. Hilar splenic vessel control was done with suture ligation. We looked at outcomes of patients offered this technique, complications of this technique, and describing the technique of hilar control in laparoscopic splenectomy. Total of 27 patients had laparoscopic splenectomy with splenic hilar pedicle control with suture ligation. Mean operative time, mean blood volume loss, length of hospital stay, postoperative complications conversion to laparotomy. Laparoscopic hilar pedicle control with suture ligation is safe and effective for the patient in our hospital setting.

The use of laparoscopy in trauma is, in general, limited for diagnostic purposes. We aim to evaluate the therapeutic role of laparoscopic surgery in trauma patients. We analyzed the National Trauma Data Bank (2007 to 2010) for all patients undergoing diagnostic laparoscopy. Patients undergoing a therapeutic laparoscopic surgical procedure were identified and tabulated. Mortality and hospital length of stay for patients with isolated abdominal injuries were compared between the open and laparoscopic groups. Of a total of 2,539,818 trauma visits in the National Trauma Data Bank, 4,755 patients underwent a diagnostic laparoscopy at 467 trauma centers. Of these, 916 (19.3%) patients underwent a therapeutic laparoscopic intervention. Common laparoscopic operations included diaphragm repair, bowel repair or resection, and splenectomy. Patients undergoing laparoscopic surgery had a significantly shorter length of stay than the open group (5 vs 6 days; P < .001). Therapeutic laparoscopic surgery for trauma is feasible and may provide better outcomes. Copyright © 2015 Elsevier Inc. All rights reserved.

Since the first laparoscopic cholecystectomy in 1988, the management of gall-bladder disease has changed importantly. This technique was rapidly popularized in the U.S. as well as in Europe. Multiple studies have proved its feasibility, safeness and great advantages. Analyze usefulness and recent advances of endoscopic surgery in the management of gallbladder disease. We did a review of the recent medical literature to determine the actual status of laparoscopic cholecystectomy. Laparoscopic cholecystectomy is the most common surgical procedure performed in the digestive tract. During the year 2001, 1,100,000 cholecystectomies were done in the U.S., 85% were done laparoscopically. In Mexico cholecystectomy in government hospitals is done laparoscopically in 50% of the cases, while in private hospitals it reaches 90%. There are multiple prospective controlled studies showing superiority of laparoscopic cholecystectomy in times of recovery, costs, return to normal activity, pain, morbidity, esthetics among other advantages. Laparoscopic cholecystectomy is the gold standard for the treatment of the great majority of cases of gallbladder disease, nevertheless in developing countries open cholecystectomy is still done frequently.

We evaluated the functional outcome, safety and efficacy of zero ischemia laparoscopic radio frequency ablation assisted tumor enucleation compared with conventional laparoscopic partial nephrectomy. A prospective randomized controlled trial was conducted from April 2013 to March 2015 in patients with cT1a renal tumor scheduled for laparoscopic nephron sparing surgery. All patients were followed for at least 12 months. Patients in the laparoscopic radio frequency ablation assisted tumor enucleation group underwent tumor enucleation after radio frequency ablation without hilar clamping. The primary outcome was the change in glomerular filtration rate of the affected kidney by renal scintigraphy at 12 months. Secondary outcomes included changes in estimated glomerular filtration rate, estimated blood loss, operative time, hospital stay, postoperative complications and oncologic outcomes. The Pearson chi-square or Fisher exact, Student t-test and Wilcoxon rank sum tests were used. The trial ultimately enrolled 89 patients, of whom 44 were randomized to the laparoscopic radio frequency ablation assisted tumor enucleation group and 45 to the laparoscopic partial nephrectomy group. In the laparoscopic partial nephrectomy group 1 case was converted to radical nephrectomy. Compared with the laparoscopic partial nephrectomy group, patients in the laparoscopic radio frequency ablation assisted tumor enucleation group had a smaller decrease in glomerular filtration rate of the affected kidney at 3 months (10.2% vs 20.5%, p=0.001) and 12 months (7.6% vs 16.2%, p=0.002). Patients in the laparoscopic radio frequency ablation assisted tumor enucleation group had a shorter operative time (p=0.002), lower estimated blood loss (p <0.001) and a shorter hospital stay (p=0.029) but similar postoperative complications (p=1.000). There were no positive margins or local recurrence in this study. Zero ischemia laparoscopic radio frequency ablation assisted tumor enucleation enables tumor excision with better renal function preservation compared to conventional laparoscopic partial nephrectomy. Less blood loss and a shorter operative time were achieved with similar postoperative complication rates. Copyright © 2016 American Urological Association Education and Research, Inc.

Polycystic ovarian syndrome (PCOS) is one of the most common reproductive endocrinology abnormalities, and affects 5% to 10% of women of reproductive age. Western medicines, such as oral contraceptives, insulin sensitizers and laparoscopic ovarian drilling (LOD), have been used to treat PCOS. Recently, many studies have been published that consider Chinese herbal medicine (CHM) as an alternative treatment for women with PCOS. To assess the efficacy and safety of CHM for subfertile women with PCOS. We searched sources, including the following databases, from inception to 9 June 2016: the Cochrane Gynaecology and Fertility Group Specialized Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, Allied and Complementary Medicine (AMED), PsycINFO, Chinese National Knowledge Infrastructure (CNKI), VIP, Wanfang and trial registries. In addition, we searched the reference lists of included trials and contacted experts in the field to locate trials. Randomized controlled trials (RCTs) that considered the use of CHM for the treatment of subfertile women with PCOS. Two review authors independently screened appropriate trials for inclusion, assessed the risk of bias in included studies and extracted data. We contacted primary study authors for additional information. We conducted meta-analyses. We used the odds ratios (ORs) to report dichotomous data, with 95% confidence intervals (CI). We assessed the quality of the evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methods. We included five RCTs with 414 participants. The comparisons in the included trials were as follows: CHM versus clomiphene, CHM plus clomiphene versus clomiphene (with or without ethinyloestradiol cyproterone acetate (CEA)), CHM plus follicle aspiration plus ovulation induction versus follicle aspiration plus ovulation induction alone, and CHM plus laparoscopic ovarian drilling (LOD) versus LOD alone. The overall quality of the evidence for most comparisons was very low.None of the included studies reported live birth rate, and only one study reported data on adverse events.When CHM was compared with clomiphene (with or without LOD in both arms), there was no evidence of a difference between the groups in pregnancy rates (odds ratio (OR) 1.98, 95% confidence interval (CI) 0.78 to 5.06; two studies, 90 participants, I² statistic = 0%, very low quality evidence). No study reported data on adverse events. When CHM plus clomiphene was compared with clomiphene (with or without CEA), there was low quality evidence of a higher pregnancy rate in the CHM plus clomiphene group (OR 2.62, 95% CI 1.65 to 4.14; three RCTs, 300 women, I² statistic = 0%,low quality evidence). No data were reported on adverse events.When CHM with follicle aspiration and ovulation induction was compared with follicle aspiration and ovulation induction alone, there was no evidence of a difference between the groups in pregnancy rates (OR 1.60, 95% CI 0.46 to 5.52; one study, 44 women, very low quality evidence), severe luteinized unruptured follicle syndrome (LUFS) (OR 0.60, 95% CI 0.06 to 6.14; one study, 44 women, very low quality evidence), ovarian hyperstimulation syndrome (OHSS) (OR 0.16, 95% CI 0.00 to 8.19; one study, 44 women, very low quality evidence) or multiple pregnancy (OR 0.60, 95% CI 0.06 to 6.14; one study, 44 women, very low quality evidence).When CHM with LOD was compared with LOD alone, there was no evidence of a difference between the groups in rates of pregnancy (OR 3.50, 95% CI 0.72 to 17.09; one study, 30 women, very low quality evidence), No data were reported on adverse events.There was no evidence of a difference between any of the comparison groups for any other outcomes. The quality of the evidence for all other comparisons and outcomes was very low. The main limitations in the evidence were failure to report live birth or adverse events, failure to describe study methods in adequate detail and imprecision due to very low event rates and wide CIs. There is insufficient evidence to support the use of CHM for women with PCOS and subfertility. No data are available on live birth, and there is no consistent evidence to indicate that CHM influences fertility outcomes. However there is very limited low quality evidence to suggest that the addition of CHM to clomiphene may improve pregnancy rates. There is insufficient evidence on adverse effects to indicate whether CHM is safe.

Cost Analysis When Open Surgeons Perform Minimally Invasive Hysterectomy

Kantartzis, Kelly L.; Ahn, Ki Hoon; Bonidie, Michael J.; Lee, Ted

2014-01-01

Background and Objective: The costs to perform a hysterectomy are widely variable. Our objective was to determine hysterectomy costs by route and whether traditionally open surgeons lower costs when performing laparoscopy versus robotics. Methods: Hysterectomy costs including subcategories were collected from 2011 to 2013. Costs were skewed, so 2 statistical transformations were performed. Costs were compared by surgeon classification (open, laparoscopic, or robotic) and surgery route. Results: A total of 4,871 hysterectomies were performed: 34.2% open, 50.7% laparoscopic, and 15.1% robotic. Laparoscopic hysterectomy had the lowest total costs (P < .001). By cost subcategory, laparoscopic hysterectomy was lower than robotic hysterectomy in 6 and higher in 1. When performing robotic hysterectomy, open and robotic surgeon costs were similar. With laparoscopic hysterectomy, open surgeons had higher costs than laparoscopic surgeons for 1 of 2 statistical transformations (P = .007). Open surgeons had lower costs performing laparoscopic hysterectomy than robotic hysterectomy with robotic maintenance and depreciation included (P < .001) but similar costs if these variables were excluded. Conclusion: Although laparoscopic hysterectomy had lowest costs overall, robotics may be no more costly than laparoscopic hysterectomy when performed by surgeons who predominantly perform open hysterectomy.

Laparoscopic appendicectomy: safe and useful for training.

PubMed Central

Duff, S. E.; Dixon, A. R.

2000-01-01

Debate exists about the benefits of laparoscopic appendicectomy when compared to a conventional open procedure. The majority of appendices are removed by the open route in the UK. We report a series of 132 cases of suspected appendicitis managed laparoscopically: 112 (85%) of the patients had acute appendicitis, the remaining 20 (15%) had non-appendiceal pathology. The median operative time was 30 min and there were no conversions to an open operative procedure. The median postoperative stay was two days. Complications were seen in two patients. The published evidence comparing laparoscopic and open appendicectomy is contradictory. Our series shows that laparoscopic appendicectomy is a safe procedure with low morbidity; it is also an excellent training tool in laparoscopic technique and, with sufficient experience, takes no longer than an open procedure. Negative appendicocecotomies are most common in women of fertile age and can be associated with significant morbidity; therefore, laparoscopy should be used to make the diagnosis and, if appendicitis is the cause, the appendix could safely be removed laparoscopically. However, the choice between open and laparoscopic procedure is a subjective decision for the patient and their surgeon. Laparoscopic appendicectomy cannot be regarded as the gold standard.

Laparoscopic surgery developed continuously over the past years becoming the gold standard for some surgical interventions. Laparoscopic colorectal surgery is well established as a safe and feasible procedure to treat benign and malignant pathologies. In this paper we studied in deep the role of laparoscopic right colectomy analysing the indications to this surgical procedure and the factors related to the conversion from laparoscopy to open surgery. We described the different surgical techniques of laparoscopic right colectomy comparing extra to intracorporeal anastomosis and we pointed out the different ways to access to the abdomen (multiport VS single incision). The indications for laparoscopic right colectomy are benign (inflammatory bowel disease and rare right colonic diverticulitis) and malignant diseases (right colon cancer and appendiceal neuroendocrine neoplasm): we described the good outcomes of laparoscopic right colectomy in all these illnesses. Laparoscopic conversion rates in right colectomy are reported as 12-16%; we described the different type of risk factors related to open conversion: patient-related, disease-related and surgeon-related factors, procedural factors and intraoperative complications. We conclude that laparoscopic right colectomy is considered superior to open surgery in the shortterm outcomes without difference in long-term outcomes.

To prevent unnecessary errors and adverse results of laparoscopic surgery, proper training is of paramount importance. A safe way to train surgeons for laparoscopic skills is simulation. For this purpose traditional box trainers are often used, however they lack objective assessment of performance. Virtual reality laparoscopic simulators assess performance, but lack realistic haptic feedback. Augmented reality (AR) combines a virtual reality (VR) setting with real physical materials, instruments, and feedback. This article presents the current developments in augmented reality laparoscopic simulation. Pubmed searches were performed to identify articles regarding surgical simulation and augmented reality. Identified companies manufacturing an AR laparoscopic simulator received the same questionnaire referring to the features of the simulator. Seven simulators that fitted the definition of augmented reality were identified during the literature search. Five of the approached manufacturers returned a completed questionnaire, of which one simulator appeared to be VR and was therefore not applicable for this review. Several augmented reality simulators have been developed over the past few years and they are improving rapidly. We recommend the development of AR laparoscopic simulators for component tasks of procedural training. AR simulators should be implemented in current laparoscopic training curricula, in particular for laparoscopic suturing training.

We characterize the use of pediatric open, laparoscopic and robot-assisted laparoscopic ureteral reimplantation in the United States from 2000 to 2012. We used the Kids' Inpatient Database to identify patients who underwent ureteral reimplantation for primary vesicoureteral reflux. Before 2009 laparoscopic ureteral reimplantion and robot-assisted laparoscopic ureteral reimplantation were referred to together as minimally invasive ureteral reimplantation. A detailed analysis of open vs robot-assisted laparoscopic ureteral reimplantation was performed for 2009 and 2012. A total of 14,581 ureteral reimplantations were performed. The number of ureteral reimplantations yearly decreased by 14.3%. However, the proportion of minimally invasive ureteral reimplantations increased from 0.3% to 6.3%. A total of 125 robot-assisted laparoscopic ureteral reimplantations were performed in 2012 (81.2% of minimally invasive ureteral reimplantations), representing 5.1% of all ureteral reimplantations, compared to 3.8% in 2009. In 2009 and 2012 mean ± SD patient age was 5.7 ± 3.6 years for robot-assisted laparoscopic ureteral reimplantation and 4.3 ± 3.3 years for open reimplantation (p <0.0001). Mean ± SD length of hospitalization was 1.6 ± 1.3 days for robot-assisted laparoscopic ureteral reimplantation and 2.4 ± 2.6 for open reimplantation (p <0.0001). Median charges were $22,703 for open and $32,409 for robot-assisted laparoscopic ureteral reimplantation (p <0.0001). These relationships maintained significance on multivariate analyses. On multivariate analysis robot-assisted laparoscopic ureteral reimplantation use was associated with public insurance status (p = 0.04) and geographic region outside of the southern United States (p = 0.02). Only 50 of 456 hospitals used both approaches (open and robotic), and only 6 hospitals reported 5 or more robot-assisted laparoscopic ureteral reimplantations during 2012. Treatment of primary vesicoureteral reflux with ureteral reimplantation is decreasing. Robot-assisted laparoscopic ureteral reimplantation is becoming more prevalent but remains relatively uncommon. Length of stay is shorter for the robotic approach but the costs are higher. Nationally robot-assisted laparoscopic ureteral reimplantation appears to still be in the early phase of adoption and is clustered at a small number of hospitals.

Laparoscopic training demands practice. The transfer of laparoscopic skills from training models to real surgical procedures has been proven. The global operative assessment of laparoscopic skills (GOALS) score is a 5-item global rating scale developed to evaluate laparoscopic skills by direct observation. This scale has been used to demonstrate construct validity of several laparoscopic training models. Here, we present a low-cost model of laparoscopic Heller-Dor for advanced laparoscopic training. The aim of this study was to determine the capability of a training model for laparoscopic Heller-Dor to discriminate between different levels of laparoscopic expertise. The performance of two groups with different levels of expertise, novices (<30 laparoscopic procedures PGY1-2) and experts (>300 laparoscopic procedures PGY4-5) was assessed. All participants were instructed to perform two tasks (esophageal myotomy and fundoplication). All the performances were recorded in a digital format. A laparoscopic expert who was blinded to subject's identity evaluated the recordings using the GOALS score. Autonomy, one of the five items of GOALS, was removed since the evaluator and the trainee did not have interaction. The time required to finish each task was also recorded. Performance was compared using the Mann-Whitney U test (p < 0.05 was significant). Twenty subjects were evaluated: ten in each group, using the GOALS score. The mean total GOALS score for novices was 7.5 points (SD: 1.64) and 13.9 points (SD: 1.66) for experts (p < 0.05).The expert group was superior in each domain of the GOALS score compared to novices: depth perception (mean: 3.3 vs 2 p < 0.05), bimanual dexterity (mean 3.4 vs 2.1 p < 0.05), efficiency (mean 3.4 vs 1.7 p < 0.05) and tissue handling (mean 3.6 vs 1.7 p < 0.05). With regard to time, experts were superior in task 1 (mean 9.7 vs 14.9 min p < 0.05) and task 2 (mean 24 vs 47.1 min p < 0.05) compared to novices. The laparoscopic Heller-Dor training model has construct validity. The model may be used as a tool for training of the surgical resident.

Summary: The rectus abdominis is a workhorse flap for perineal reconstruction, in particular after abdominoperineal resection (APR). Laparoscopic and robotic techniques for abdominoperineal surgery are becoming more common. The open harvest of the rectus abdominis negates the advantages of these minimally invasive approaches. (Sentence relating to advantages of laparoscopic rectus deleted here.) We present our early experience with laparoscopic harvest of the rectus muscle for perineal reconstruction. Three laparoscopic unilateral rectus abdominis muscle harvests were performed for perineal reconstruction following minimally invasive colorectal and urological procedures. The 2 patients who underwent APR also had planned external perineal skin reconstruction with local flaps. (Sentence deleted here to shorten abstract.) All rectus muscle harvests were performed laparoscopically. Two were for perineal reconstruction following laparoscopic APR, and 1 was for anterior vaginal wall reconstruction. This was done with 4 ports positioned on the contralateral abdomen. The average laparoscopic harvest time was 60–90 minutes. The rectus muscle remained viable in all cases. One patient developed partial necrosis of a posterior thigh fasciocutaneous flap after cancer recurrence. There were no pelvic abscesses, or abdominal wall hernias. Laparoscopic harvest of the rectus appears to be a cost-effective, reliable, and reproducible procedure for perineal with minimal donor-site morbidity. Larger clinical studies are needed to further establish the efficacy and advantages of the laparoscopic rectus for perineal reconstruction. PMID:29263976

Laparoscopic surgery for colorectal disease has become widespread as a minimally invasive treatment. This is important because the increasing availability of new devices allows us to perform procedures with a reduced length of surgery and decreased blood loss. We herein report the results of a literature review of energy sources for laparoscopic colorectal surgery, focused especially on 6 studies comparing ultrasonic coagulating shears (UCS) and other instruments. We also describe our laparoscopic dissection techniques using UCS for colorectal cancer. The short-term outcomes of surgeries using UCS and Ligasure for laparoscopic colorectal surgery were superior to conventional electrosurgery. Some authors have reported that the length of surgery or blood loss when Ligasure was used for laparoscopic colorectal surgery is less than when UCS was used. On the other hand, a recent study demonstrated that there were no significant differences between the short-term outcomes of UCS and Ligasure for laparoscopic colorectal surgery. It is therefore suggested that the choice of technique used should be made according to the surgeon’s preference. We also describe our laparoscopic dissection techniques using UCS (Harmonic ACE) for colorectal cancer with regard to the retroperitoneum dissection, dissection technique, dissection technique around the feeding artery, and various other dissection techniques. We therefore review the outcomes of using various energy sources for laparoscopic colorectal surgery and describe our laparoscopic dissection techniques with UCS (Harmonic ACE) for colorectal cancer.

Alekberzade, A V; Krylov, N N; Rustamov, E A; Badalov, D A; Popovtsev, M A

To compare laparoscopic and open closure of perforated peptic ulcer (PPU). The study included 153 patients who underwent PPU suturing. 78 patients underwent laparoscopic closure (laparoscopic group) and open suturing via upper midline laparotomy was performed in 75 cases (open group). Surgery time, postoperative pain severity, time of analgesics intake, postoperative complications, hospital-stay and and cosmetic effect were compared. Laparoscopic PPU closure may be effective and accessible in experienced endoscopic surgeon. It significantly reduces postoperative pain severity, need for analgesics, incidence of postoperative complications and provides excellent cosmetic effect. However, there is greater time of surgery compared with open intervention. There were no significant differences in hspital-stay between groups. Laparoscopic PPU suturing can be considered a good alternative to open surgery. Further researches are needed for standardization, assessment of safety, real advantages and disadvantages of laparoscopic technique.

The introduction of new surgical techniques has made training in laparoscopic procedures a necessity for the practicing surgeon, but acquisition of new surgical skills is a formidable task. This study was conducted to assess the impact of advanced laparoscopic workshops on caseload patterns of practicing surgeons. After we obtained institutional review board approval, a survey of practicing surgeons who participated in advanced laparoscopic courses was distributed; the results were analyzed for statistical significance. The courses were held at the University of Nebraska Medical Center between January 2002 and December 2010. Questionnaires were mailed, faxed, and e-mailed to surgeons. Of the 109 surgeons who participated in the advanced laparoscopy courses, 79 received surveys and 30 were excluded from the survey because of their affiliation with the University of Nebraska Medical Center. A total of 47 responses (59%) were received from 41 male and 6 female surgeons. The median response time from completion of the course to completion of the survey was 13.2 months (range, 6.8-19.1 months). The mean age of participating surgeons was 39.2 years (range, 29-51 years). The mean time since residency was 8.4 years (range, 0.8-21 years). Eleven surgeons had completed a minimal number of laparoscopic cases in residency (<50), 17 surgeons had completed a moderate number of laparoscopic procedures in residency (50-200), and 21 surgeons had completed a significant number of cases during residency (>200). Of the surgeons who responded, 94% were in private practice. Fifty-seven percent of the participating surgeons who responded reported a change in laparoscopic practice patterns after the courses. Of these surgeons, 24% had a limited residency laparoscopy exposure of <50 cases. Surgeons who were exposed to ≥50 laparoscopic cases during their residency showed a statistically significant increase in the number of laparoscopic procedures performed after their class compared with surgeons who did not receive ≥50 laparoscopic cases in residency (P = .03). In addition, regardless of the procedures learned in a specific class, surgeons with ≥50 laparoscopic cases in residency had a statistically significant increase in their laparoscopic colectomy and laparoscopic hernia procedure caseload (P < .01). However, there was no statistically significant difference in laparoscopic caseload between surgeons who had completed 50 to 200 laparoscopic residency cases and those who had completed greater than 200 laparoscopic residency cases (P = .31). Furthermore, the participant's age (P = .23), practice type (P = .61), and years in practice (P = .22) had no statistical significance with regard to the adoption of laparoscopic procedures after courses taken. This finding is congruent with the findings of other researchers. Future interest in advanced laparoscopy courses was noted in 70% of surgeons and was more pronounced in surgeons with ≥50 cases in residency. Advanced laparoscopic workshops provide an efficacious instrument in educating surgeons on minimally invasive surgical techniques. Participating surgeons significantly increased the number of course-specific procedures that they performed but also increased the number of other laparoscopic surgeries, suggesting that a certain proficiency in laparoscopic skills is translated to multiple surgical procedures. Laparoscopy experience of ≥50 cases during residency is a strong predictor of an increase in the number of advanced laparoscopic cases after attending courses.

Although the many advantages of laparoscopic surgery have made it an established technique, training in laparoscopic surgery posed problems not encountered in conventional surgical training. Virtual reality simulators open up new perspectives for training in laparoscopic surgery. Under realistic conditions in real time, trainees can tailor their sessions with the VR simulator to suit their needs and goals, and can repeat exercises as often as they wish. VR simulators reduce the number of experimental animals needed for training purposes and are suited to the pursuit of research in laparoscopic surgery.

Laparoscopic pyeloplasty is used for the repair of ureteropelvic junction (UPJ) obstruction. Our objective was to introduce laser soldering to this procedure. We developed a system based on a CO2 laser, an infrared detector, and two infrared transmitting optical fibers to obtain temperature-controlled laser soldering of cuts in tissues. The system was used for laparoscopic soldering of incisions in the kidneys of pigs. We carried out laparoscopic pyeloplasty successfully in a porcine model using fiberoptic laser soldering. Laparoscopic laser soldering was found to be faster than suturing. It was easier to use and provided watertight bonding. This technique will be useful in pyeloplasty as well as other laparoscopic surgical procedures.

Evidence supporting laparoscopic hernia repair in children.

PubMed

Jessula, Samuel; Davies, Dafydd A

2018-06-01

Pediatric inguinal hernias are a commonly performed surgical procedure. Currently, they can be approached via open or laparoscopic surgery. We summarize the current evidence for laparoscopic inguinal hernia repairs in children. Laparoscopic and open inguinal hernia repair in children are associated with similar operative times for unilateral hernia, as well as similar cosmesis, complication rates and recurrence rates. Bilateral hernia repair has been shown to be faster through a laparoscopic approach. The laparoscopic approach is associated with decreased pain scores and earlier recovery, although only in the initial postoperative period. Laparoscopy allows for easy evaluation of the patency of contralateral processus vaginalis, although the clinical significance of and need for repair of an identified defect is unclear. Laparoscopic surgery for pediatric inguinal hernias offers some advantages over open repair with most outcomes being equal. It should be considered a safe alternative to open repair to children and their caregivers.

The management of choledocholithiasis has changed radically since the introduction of laparoscopic cholecystectomy. However, perceived technical difficulties have deterred many surgeons from treating common bile duct stones laparoscopically at the time of cholecystectomy. This has lead to reliance on endoscopic retrograde cholangiopancreatography followed by endoscopic sphincterotomy to deal with common bile duct stones. We retrospectively reviewed the charts of patients who had laparoscopic common bile duct exploration at Downe Hospital between December 1999 and August 2001. Among 149 laparoscopic cholecystectomies done by our group in this period, 10 patients (6.7%) underwent laparoscopic CBD exploration, three by the transcystic technique and seven by choledochotomy. Three patients (2%) had unsuspected stones found on routine per- operative cholangiogram. The mean operative time was 2.34hrs (range 1.50-3.30hrs). The mean hospital post- operative stay was 3 days (range 1-6 days). Post-operative morbidity was zero. Stone clearance was achieved in all cases. We conclude, laparoscopic exploration of the common bile duct is relatively safe and straightforward method. The key skill required is the ability to perform laparoscopic suturing with confidence.

Prof Dr Med Erich Mühe of Böblingen, Germany, performed the first laparoscopic cholecystectomy on September 12, 1985. The German Surgical Society rejected Mühe in 1986 after he reported that he had performed the first laparoscopic cholecystectomy, yet in 1992 he received their highest award, the German Surgical Society Anniversary Award. In 1990 in Atlanta, at the Society of American Gastrointestinal Surgeons (SAGES) Convention, Perissat, Berci, Cuschieri, Dubois, and Mouret were recognized by SAGES for performing early laparoscopic cholecystectomies, but Mühe was not. However, in 1999 he was recognized by SAGES for having performed the first laparoscopic cholecystectomy–sAGES invited Mühe to present the Storz Lecture. In Mühe's presentation, titled “The First Laparoscopic Cholecystectomy,” which he gave in March 1999 in San Antonio, Texas, he described the first procedure. Finally, Mühe had received the worldwide acclaim that he deserved for his pioneering work. One purpose of this article is to trace the development of the basic instruments used in laparoscopic cholecystectomy. The other purpose is to give Mühe the recognition he deserves for being the developer of the laparoscopic cholecystectomy procedure. PMID:11304004

Background Minimally invasive surgery, including laparoscopic and robotic gastrectomy, has become more popular in the treatment of gastric cancer. However, few studies have compared the learning curves between laparoscopic and robotic gastrectomy for gastric cancer. Methods Data were prospectively collected between July 2008 and Aug 2014. A total of 145 patients underwent minimally invasive gastrectomy for gastric cancer by a single surgeon, including 73 laparoscopic and 72 robotic gastrectomies. The clinicopathologic characteristics, operative outcomes and learning curves were compared between the two groups. Results Compared with the laparoscopic group, the robotic group was associated with less blood loss and longer operative time. After the surgeon learning curves were overcome for each technique, the operative outcomes became similar between the two groups except longer operative time in the robotic group. After accumulating more cases of robotic gastrectomy, the operative time in the laparoscopic group decreased dramatically. Conclusions After overcoming the learning curves, the operative outcomes became similar between laparoscopic and robotic gastrectomy. The experience of robotic gastrectomy could affect the learning process of laparoscopic gastrectomy. PMID:25360767

Background The aim of this study is to compare the perioperative and oncologic outcomes of open and laparoscopic approaches for concomitant resection of synchronous colorectal cancer and liver metastases. Methods Between 2006 and 2015, all patients undergoing combined resection of primary colorectal cancer and liver metastases were included in the study (n=43). Laparoscopic and open groups were compared regarding clinical, perioperative and oncologic outcomes. Results There were 29 patients in the open group and 14 patients in the laparoscopic group. The groups were similar regarding demographics, comorbidities, histopathological characteristics of the primary tumor and liver metastases. Postoperative complication rate (44.8% vs. 7.1%, P=0.016) was higher, and hospital stay (10 vs. 6.4 days, P=0.001) longer in the open compared to the laparoscopic group. Overall survival (OS) was comparable between the groups (P=0.10); whereas, disease-free survival (DFS) was longer in laparoscopic group (P=0.02). Conclusions According to the results, in patients, whose primary colorectal cancer and metastatic liver disease was amenable to a minimally invasive resection, a concomitant laparoscopic approach resulted in less morbidity without compromising oncologic outcomes. This suggests that a laparoscopic approach may be considered in appropriate patients by surgeons with experience in both advanced laparoscopic liver and colorectal techniques. PMID:28861371

AIM: To evaluate the long-term clinical and oncological outcomes of laparoscopic rectal resection (LRR) and the impact of conversion in patients with rectal cancer. METHODS: An analysis was performed on a prospective database of 633 consecutive patients with rectal cancer who underwent surgical resection. Patients were compared in three groups: Open surgery (OP), laparoscopic surgery, and converted laparoscopic surgery. Short-term outcomes, long-term outcomes, and survival analysis were compared. RESULTS: Among 633 patients studied, 200 patients had successful laparoscopic resections with a conversion rate of 11.1% (25 out of 225). Factors predictive of survival on univariate analysis include the laparoscopic approach (P = 0.016), together with factors such as age, ASA status, stage of disease, tumor grade, presence of perineural invasion and vascular emboli, circumferential resection margin < 2 mm, and postoperative adjuvant chemotherapy. The survival benefit of laparoscopic surgery was no longer significant on multivariate analysis (P = 0.148). Neither 5-year overall survival (70.5% vs 61.8%, P = 0.217) nor 5-year cancer free survival (64.3% vs 66.6%, P = 0.854) were significantly different between the laparoscopic group and the converted group. CONCLUSION: LRR has equivalent long-term oncologic outcomes when compared to OP. Laparoscopic conversion does not confer a worse prognosis. PMID:27358678

Between 1994 and 2008, a total of 114 patients (29 males and 85 females, median age 54 years) with adrenal Cushing's/subclinical Cushing's syndrome were studied. We compared the outcome of patients who underwent laparoscopic adrenalectomy between intraperitoneal and retroperitoneal approaches. Surgical complications were graded according to the Clavien grading system. We also examined the long-term results of subclinical Cushing's syndrome after laparoscopic adrenalectomy. Laparoscopic surgical outcome did not differ significantly between patients with Cushing's syndrome and those with subclinical Cushing's syndrome. Patients who underwent laparoscopic intraperitoneal adrenalectomy had longer operative time than those who received retroperitoneal adrenalectomy (188.2 min vs. 160.9 min). However, operative blood loss and surgical complications were similar between both approaches. There were no complications of Clavien grade III or higher in either intraperitoneal or retroperitoneal approach. We confirmed the improvement of hypertension and glucose tolerance in patients with subclinical Cushing's syndrome after laparoscopic adrenalectomy. Laparoscopic adrenalectomy for adrenal Cushing's/subclinical Cushing's syndrome is safe and feasible in either intraperitoneal or retroperitoneal approach. The use of the Clavien grading system for reporting complications in the laparoscopic adrenalectomy is encouraged for a valuable quality assessment.
