    Rectal prolapse as the initial clinical manifestation of colorectal cancer is uncommon. We describe the case of a 75-year-old woman who was diagnosed as having adenocarcinoma of the sigmoid colon after presenting with complete rectal prolapse. The tumor caused rectosigmoid intussusception and then it prolapsed out through the anus. She underwent rectosigmoidectomy and rectopexy. The postoperative course was uneventful. The relationship between colorectal cancer and rectal prolapse has not been clearly established. This case report describes an unusual presentation of colorectal cancer. It suggests that rectal prolapse can present as the initial symptom of colorectal cancer and may also be a presenting feature of the occult intra-abdominal pathology. The importance of adequate investigation such as colonoscopy should be emphasized in patients who develop a new onset of rectal prolapse.

    During the 1994 crisis in Rwanda, a high incidence of full-thickness rectal prolapse was noted among the refugee children in the south-west of the country. The prolapses arose as a result of acute diarrhoeal illness superimposed on malnutrition and worm infestation. We used a modification of the Thiersch wire technique in 40 of these cases during two months working in a refugee camp. A catgut pursestring was tied around the anal margin under local, regional or general anaesthesia. This was effective in achieving short-term control of full-thickness prolapse until the underlying illness was corrected. Under the circumstances, no formal follow-up could be arranged; however, no complications were reported and only one patient presented with recurrence. Images Figure 1 PMID:9014879

    Rectal Prolapse is a rare and distressing condition, with a multifactorial etiopathogenesis. Often, this pathology is associated with fecal incontinence. The recommended approach to the patient with rectal prolapse and fecal incontinence is to repair the prolapse first, then deal particularly with fecal incontinence at a second operation. A retrospective, clinical and manometric study has varying degrees of fecal incontinence. Clinically five of their operation, and a further three patients improved, in two patients the degree of fecal incontinence remained invariable. One patient was worsened after surgery. Manometrically resting and pressure (RAP) was significantly higher in continent patients than in voluntary contraction pressure (MVCP) (p < 0.05) in preoperative testing. Postoperatively, there was a significant increase in the resting anal pressure as well as in maximum voluntary contraction pressure. Patients who remained incontinent had a significantly lower RAP and MVCP than patients who improved our regained continence. In conclusion this study shows an alteration of internal and external sphincteric function in patients with rectal prolapse. The surgical treatment of this disease improves sphincteric function. Incontinent patients with RAP < 10 mmHg and MCVP < 20 mmHg, probably they would be better treated simultaneously either for rectal prolapsus and incontinence. In this kind of patients the perianal proctectomy with total sphincteroplasty could be the elective treatment.

    Solitary rectal ulcer syndrome is a rare clinical entity. Several treatment options has been described. However, there is no consensus yet on treatment algorithm and standard surgical procedure. Rectopexy is one of the surgical options and it is generally performed in patients with solitary rectal ulcer accompanied with overt prolapse. Various outcomes have been reported for rectopexy in the patients with occult prolapse or rectal intussusception. In the literature; outcomes of laparoscopic non-resection rectopexy procedure have been reported in the limited number of case or case series. No study has emphasized the outcomes of laparoscopic non-resection rectopexy procedure in the patients with solitary rectal ulcer without overt prolapse. In this report we aimed to present clinical outcomes of laparoscopic non-resection posterior suture rectopexy procedure in a 21-year-old female patient with solitary rectal ulcer without overt prolapse.

    A stranguled rectal prolapse is a rare cause of intestinal occlusion. It requires emergency surgery. A patient who underwent emergency perineal proctectomy, the Altemeier operation, combined with diverting loop sigmoid colostomy is described. The postoperative course was uneventful, with an excellent final result after colostomy closure. The successful treatment of this patient illustrates the value of the Altemeier procedure in the difficult and unusual scenario of bowel incarceration.

    Introduction Rectal prolapse occurs particularly in elder females and presentation can sometimes lead to complications such as strangulation and evisceration of other organs through the necrotic mucosa. Presentation of case This is a case of a 61 year-old female with rectal prolapse complicated by rectal perforation through which a segment of sigmoid colon eviscerated and became strangulated. This patient initially presented with sepsis requiring ICU admission, but fully recovered following a Hartmann’s procedure with a sacral rectopexy. Discussion Complications of rectal prolapse include incarceration, strangulation, and rarely, perforation with evisceration of other viscera requiring urgent operation. This report provides a brief overview of complications associated with rectal prolapse, reviews similar cases of transrectal evisceration, and discusses the management of chronic rectal prolapse. Conclusion Prompt surgical consult is warranted if any signs or symptoms suggestive of complications from prolapse are present. PMID:25680532

    Patient: Female, 39 Final Diagnosis: Recurrent strangulated rectal prolapse Symptoms: Chronic constipation • painful rectal mass • irreducible rectal prolapse Medication: — Clinical Procedure: Operation Specialty: Surgery Objective: Management of emergency care Background: Rectal prolapse is an uncommon disease that usually requires surgical intervention. Several techniques have been described with either an abdominal or perineal approach, the latter having a higher recurrence rate. In case of irreducible and strangulated full-thickness prolapse, a perineal approach is necessary, and efforts should be made to reduce recurrence rates. Case Report: A 39-year-old mentally retarded woman presented with a painful, recurrent, strangulated sigmoid prolapse following a perineal recto-sigmoidectomy (Altemeier’s procedure) for strangulated rectal prolapse 2 months previously. Examination revealed a 10-cm strangulated, prolapsed sigmoid. A laparoscopic-assisted perineal sigmoid resection with colo-anal anastomosis was carried out. The patient made an uneventful recovery and was discharged on the 6th postoperative day. Conclusions: This is the second report in the literature highlighting the role of laparoscopy in Altemeier’s procedure for strangulated prolapse. Laparoscopy aids assessment of sigmoid length, allows colonic mobilization, and assures that all redundant bowel is excised. This approach can reduce recurrence rate and need of further surgical interventions. PMID:27811832

    Rectal prolapse occurred in 112 (18.5%) of 605 cystic fibrosis patients. In 48 patients prolapse preceded diagnosis of cystic fibrosis, but physicians (pediatricians, pediatric and general surgeons, and proctologists) rarely appreciated its importance as a symptom of this disease. Prolapses frequently cease with institution of pancreatic enzyme replacement therapy following diagnosis of cystic fibrosis. However, even when the disease remains undiagnosed, the symptom is often transient and frequently resolves at 3-5 yr of age. Prolapse occurring initially after cystic fibrosis is diagnosed rarely responds to manipulation of diet or enzyme doses. Many patients develop a method of reduction which involves voluntary abdominal, perineal, and gluteal muscles and does not require manual pressure on the prolapsed segment. Most patients do not need specific treatment for the prolapse. Surgery is rarely necessary. A sweat test should be obtained on any child who has had even a single episode of rectal prolapse.

    Incarceration of a rectal prolapse is an unusual entity that represents a surgical emergency. Even more rarely, it becomes strangulated, requiring emergency surgery. When surgery becomes inevitable, the choice of procedure varies. A 57-year-old man who presented with strangulated rectal prolapse is described. The patient underwent emergency perineal proctosigmoidectomy, the Altemeier operation, combined with diverting loop sigmoid colostomy. The postoperative course was uneventful. After a 6-month follow-up, there was no recurrence, but the patient continued with fecal incontinence. This case underlines the importance of the Altemeier procedure as treatment in the patient with a strangulated prolapsed rectal segment.

    A retrospective study was conducted to investigate the cause of rectal prolapse in working donkeys in Ethiopia. Analysis of data on rectal prolapse cases obtained from the Donkey Health and Welfare Project clinic at the School of Veterinary Medicine, Addis Ababa University, from 1995 to 2004 revealed that 83.6% (n = 177) of the cases were associated with Gasterophilus nasalis. The rest 10.7% and 5.7% were associated with work-related (overloading) cause and diarrhoea, respectively. The mean and median numbers of G. nasalis recovered from the rectum of infected donkeys were 66 and 64, respectively, with a range of 2-195. Over 100 G. nasalis larvae were recovered from the rectum of 22% of the donkeys. Circular demarcated ulcer-like and deep circumferential pits or ring-like mucosal lesions were found at the larval attachment sites. G. nasalis infection and the associated rectal prolapse were observed year round. However, the intensity of rectal larval infection and incidence of rectal prolapse were significantly higher during the rainy season (P < 0.01). Age and sex of the donkeys had no significant effect on the intensity of rectal larval infection and incidence of rectal prolapse (P > 0.05).

    Rectal prolapse is a rectal static disorder which involves rectal wall intussusception inducing its externalization through the anus. It usually affects children and the elderly. Its occurrence in young adults is rare. Strangulated rectal prolapse is also a rare complication. We report the case of a 30-year old patient who underwent emergency surgery for strangulated rectal prolapse. Emergency perineal rectosigmoidectomy (Altemeier repair) was performed with simple outcome.

    Perineal procedures have higher recurrence and lower mortality rates than abdominal alternatives for the treatment of rectal prolapse. Presence of incarceration and strangulation also influences treatment choice. Perineal rectosigmoidectomy is one of the treatment options in patients with incarceration and strangulation, with low mortality and acceptable recurrence rates. This operation can be performed especially to avoid general anesthesia in old patients with co-morbidities. We aimed to present perineal rectosigmoidectomy and diverting loop colostomy in a patient with neurological disability due to spinal trauma and incarcerated rectal prolapse. PMID:27528816

    Background A new surgical technique, the Perineal Stapled Prolapse resection (PSP) for external rectal prolapse was introduced in a feasibility study in 2008. This study now presents the first results of a larger patient group with functional outcome in a mid-term follow-up. Methods From December 2007 to April 2009 PSP was performed by the same surgeon team on patients with external rectal prolapse. The prolapse was completely pulled out and then axially cut open with a linear stapler at three and nine o'clock in lithotomy position. Finally, the prolapse was resected stepwise with the curved Contour® Transtar™ stapler at the prolapse's uptake. Perioperative morbidity and functional outcome were prospectively measured by appropriate scores. Results 32 patients participated in the study; median age was 80 years (range 26-93). No intraoperative complications and 6.3% minor postoperative complications occurred. Median operation time was 30 minutes (15-65), hospital stay 5 days (2-19). Functional outcome data were available in 31 of the patients after a median follow-up of 6 months (4-22). Preoperative severe faecal incontinence disappeared postoperatively in 90% of patients with a reduction of the median Wexner score from 16 (4-20) to 1 (0-14) (P < 0.0001). No new incidence of constipation was reported. Conclusions The PSP is an elegant, fast and safe procedure, with good functional results. Trial registration ISRCTN68491191 PMID:20205956

    Internal rectal prolapse (IRP) is a well-recognized pelvic floor disorder mainly seen during defecatory straining. The symptomatic expression of IRP is complex, encompassing fecal continence (56%) and/or evacuation disorders (85%). IRP cannot be characterized easily by clinical examination alone and the emergence of dynamic defecography (especially MRI) has allowed a better comprehension of its pathophysiology and led to the proposition of a severity score (Oxford score) that can guide management. Decision for surgical management should be multidisciplinary, discussed after a complete work-up, and only after medical treatment has failed. Information should be provided to the patient, outlining the goals of treatment, the potential complications and results. Stapled trans-anal rectal resection (STARR) has been considered as the gold standard for IRP treatment. However, inconsistent results (failure observed in up to 20% of cases, and fecal incontinence occurring in up to 25% of patients at one year) have led to a decrease in its indications. Laparoscopic ventral mesh rectopexy has substantial advantages in solving the functional problems due to IRP (efficacy on evacuation and resolution of continence symptoms in 65-92%, and 73-97% of patients, respectively) and is currently considered as the gold standard therapy for IRP once the decision to operate has been made.

    AIM: To report our experience with perineal repair (Delorme’s procedure) of rectal prolapse with particular focus on treatment of the recurrence. METHODS: Clinical records of 40 patients who underwent Delorme’s procedure between 2003 and 2014 were reviewed to obtain the following data: Gender; duration of symptoms, length of prolapse, operation time, ASA grade, length of post-operative stay, procedure-related complications, development and treatment of recurrent prolapse. Analysis of post-operative complications, rate and time of recurrence and factors influencing the choice of the procedure for recurrent disease was conducted. Continuous variables were expressed as the median with interquartile range (IQR). Statistical analysis was carried out using the Fisher exact test. RESULTS: Median age at the time of surgery was 76 years (IQR: 71-81.5) and there were 38 females and 2 males. The median duration of symptoms was 6 mo (IQR: 3.5-12) and majority of patients presented electively whereas four patients presented in the emergency department with irreducible rectal prolapse. The median length of prolapse was 5 cm (IQR: 5-7), median operative time was 100 min (IQR: 85-120) and median post-operative stay was 4 d (IQR: 3-6). Approximately 16% of the patients suffered minor complications such as - urinary retention, delayed defaecation and infected haematoma. One patient died constituting post-operative mortality of 2.5%. Median follow-up was 6.5 mo (IQR: 2.15-16). Overall recurrence rate was 28% (n = 12). Recurrence rate for patients undergoing an urgent Delorme’s procedure who presented as an emergency was higher (75.0%) compared to those treated electively (20.5%), P value 0.034. Median time interval from surgery to the development of recurrence was 16 mo (IQR: 5-30). There were three patients who developed an early recurrence, within two weeks of the initial procedure. The management of the recurrent prolapse was as follows: No further intervention (n = 1

    AIM To investigate the assumption that schistosomiasis is the main cause of rectal prolapse in young Egyptian males. METHODS Twenty-one male patients between ages of 18 and 50 years with complete rectal prolapse were included in the study out of a total 29 patients with rectal prolapse admitted for surgery at Colorectal Surgery Unit, Ain Shams University hospitals between the period of January 2011 and April 2014. Patients were asked to fill out a specifically designed questionnaire about duration of the prolapse, different bowel symptoms and any past or present history of schistosomiasis. Patients also underwent flexible sigmoidoscopy and four quadrant mid-rectal biopsies documenting any gross or microscopic rectal pathology. Data from questionnaire and pathology results were analyzed and patients were categorized according to their socioeconomic class. RESULTS Twelve patients (57%) never contracted schistosomiasis and were never susceptible to the disease, nine patients (43%) had history of the disease but were properly treated. None of the patients had gross rectal polyps and none of the patients had active schistosomiasis on histopathological examination. Fifteen patients (71%) had early onset prolapse that started in childhood, majority before the age of 5 years. Thirteen patients (62%) were habitual strainers, and four of them (19%) had straining dating since early childhood. Four patients (19%) stated that prolapse followed a period of straining that ranged between 8 mo and 2 years. Nine patients (43%) in the present study came from the low social class, 10 patients (48%) came from the working class and 2 patients (9%) came from the low middle social class. CONCLUSION Schistosomiasis should not be considered the main cause of rectal prolapse among young Egyptian males. Childhood prolapse that continues through adult life is likely involved. Childhood prolapse probably results from malnutrition, recurrent parasitic infections and diarrhea that induce

    In patients with rectal prolapse is the prevalence of colorectal cancer increased, suggesting that a colorectal tumor may induce rectal prolapse. Establishment of tumor xenografts in immunodeficient mice after orthotopic inoculations of human colorectal cancer cells into the caecal wall is a widely used approach for the study of human colorectal cancer progression and preclinical evaluation of therapeutics. Remarkably, 70% of young mice carrying a COLO320DM caecal tumor showed symptoms of intussusception of the large bowel associated with intestinal lumen obstruction and rectal prolapse. The quantity of the COLO320DM bioluminescent signal of the first three weeks post-inoculation predicts prolapse in young mice. Rectal prolapse was not observed in adult mice carrying a COLO320DM caecal tumor or young mice carrying a HT29 caecal tumor. In contrast to HT29 tumors, which showed local invasion and metastasis, COLO320DM tumors demonstrated a non-invasive tumor with pushing borders without presence of metastasis. In conclusion, rectal prolapse can be linked to a non-invasive, space-occupying COLO320DM tumor in the gastrointestinal tract of young immunodeficient mice. These data reveal a model that can clarify the association of patients showing rectal prolapse with colorectal cancer. PMID:27689329

    In recent years the number of patients with partial or total rectal prolapse has increased. Numerous techniques and surgical approaches have been described for its treatment. In this study we examine the main ones and stress the advantages of the transanal-perineal resection technique according to Altemeier and modified by Prasad, which we have used to treat the condition in the last 15 years. From 1988 to 2002, 269 patients with "haemorrhoidal prolapse" were referred to our department; 146 were females (54%), and the mean age was 58 years. Clinical examination and proctosigmoidoscopy revealed the presence of total rectal prolapse in 41 patients (15%, 32 F, 9 M), complicated in 4 cases by moderate incontinence and associated in 3 cases with post-haemorrhoidectomy stenosis. These 41 patients underwent transanal resection according to Altemeier. Thirty-four of them (83%) were operated on under local anaesthesia with sedation, 5 patients (12%) under peridural anaesthesia and 2 patients (5%) under narcosis. The mean hospital stay was 5 days and depended on the time of the first spontaneous evacuation. Check-ups were performed after 7 days, 1 months and every 3 months for 1 year. There was no postoperative mortality, and only 1 case of postoperative haemorrhage, which did not require reoperation, in a patient with a previous myocardial infarct who spontaneously continued to take salicylates up to 24 h before surgery. Thirty-three patients (80%) had their first postoperative evacuation within 48 h of surgery after taking sorbitol orally in the evening, 6 patients (15%) within 72 h, and 2 patients (5%) on postoperative day 4. No evacuative enemas were performed. We observed clinical healing in all patients 1 month after the operation, and regular, spontaneous evacuations without the use of oral laxatives. Stool or gas incontinence were never observed or reported. During the follow-up, only in 2% of cases did we observe partial recurrence of the prolapse. The choice

    External and internal rectal prolapse with their affiliated rectocele and enterocele, are associated with debilitating symptoms such as obstructed defecation, pelvic pain and faecal incontinence. Since perineal procedures are associated with a higher recurrence rate, an abdominal approach is commonly preferred. Despite the description of greater than three hundred different procedures, thus far no clear superiority of one surgical technique has been demonstrated. Ventral mesh rectopexy (VMR) is a relatively new and promising technique to correct rectal prolapse. In contrast to the abdominal procedures of past decades, VMR avoids posterolateral rectal mobilisation and thereby minimizes the risk of postoperative constipation. Because of a perceived acceptable recurrence rate, good functional results and low mesh-related morbidity in the short to medium term, VMR has been popularized in the past decade. Laparoscopic or robotic-assisted VMR is now being progressively performed internationally and several articles and guidelines propose the procedure as the treatment of choice for rectal prolapse. In this article, an outline of the current status of laparoscopic and robotic ventral mesh rectopexy for the treatment of internal and external rectal prolapse is presented. PMID:27275090

    Background To assess the role of the surged faradic stimulation to the pelvic floor muscles as an adjunct to the conservative management in the children of idiopathic rectal prolapse Methods Study design: Prospective Setting: Pediatric Surgery Department, Pt BD Sharma, Post Graduate Institute of Medical Sciences, Rohtak Subjects: 47 consecutive children with idiopathic rectal prolapse attending the Pediatric Surgery out patient department from July 2005 to June 2006 Methodology: The information pertaining to duration and the extent of rectal prolapse, predisposing or associated medical conditions, results of local clinical examination were noted. Surged faradic stimulation using modified intraluminal rectal probe, was given on the alternate days. The conventional conservative medical management was also continued. The extent of relief and the number of the sittings of faradic stimulation required were noted at various stages of follow-ups Statistical Methods: Mean values between those completely cured and others; poor responders and others were compared with t-test and proportions were compared with Chi square test. The p-value < 0.05 was considered statistically significant. Results The mean number of sittings in the completely cured group (n = 28(64%)) was (12.4 ± 7.8) and was comparable with very poor responder (n = 6(13%). There was higher percentage of relief (76%) at the first follow up (at 15 days) in completely cured Vs other (37%) and also the poor responders showed (20%) Vs other (68%) and was statistically significant. Conclusion With use of faradic stimulation, even the long-standing rectal prolapse can be fully cured. The follow up visit at 2 weeks is very important to gauge the likely success of this modality in treatment of the patients with rectal prolapse. Those showing poor response at this stage may require alternative treatment or take a long time to get cured PMID:19602234

    Introduction Transanal evisceration of small bowel is an extremely rare surgical emergency. Of the nearly 70 cases reported in the literature, rectal prolapse is the predisposing factor that has been most frequently related to this pathology. Presentation of case We report a 78-year-old female with history of chronic rectal prolapse who presented in our emergency department with evisceration of small intestinal loops through the anus. In surgery after complete reduction of the eviscerated bowel into the peritoneal cavity, almost 20 cm of the terminal ileum up to the ileocecal valve were necrotic and therefore a right hemicolectomy with primary anastomosis was performed. Additionally a 2 cm craniocaudally tear was revealed in the antimesenteric border of the upper rectum and a Hartman procedure was also performed. The patient was discharged after 10 days. Discussion Early recognition and timely surgical intervention offers the best prognosis, avoiding a fatal conclusion or an extensive intestinal resection. PMID:26708948

    Spontaneous rupture of the rectum is a rare occurrence. A total laparoscopic approach to rectal perforation has only occasionally been reported. We report an unusual case of a young boy who developed a spontaneous rupture of the rectum following a trivial fall. A magnetic resonance imaging revealed a tear in the rectum at the peritoneal reflection with the omentum plugging it. He denied any history of rectal instrumentation or abnormal sexual activity. He had no history of constipation or rectal prolapse. The tear was repaired laparoscopically and a covering loop sigmoid colostomy was added. He made an uneventful post-operative recovery. Spontaneous rupture of the rectum can occur in younger age groups and even in the absence of significant trauma. One needs to diligently bring out a history of rectal trauma. Equally important is to rule out any underlying pathological condition. A laparoscopic approach is feasible, especially in early cases. PMID:28281483

    Evisceration of small intestine through anus is a rare presentation in emergency. We reported a case with long history of recurrent complete rectal prolapse presenting in emergency as small bowel protruding out through anal orifice. The small bowel herniated out from a spontaneous perforation in rectosigmoid. After resuscitation, emergency exploratory laparotomy was carried out and small bowel was reposited in the peritoneal cavity through the site of perforation by pulling and pushing maneuvere and the perforated segment of rectosigmoid was exteriorised as double barrel colostomy.

    This case demonstrates the successful treatment of a young female patient with colitis cystica profunda causing rectal prolapse, after primary treatment with a Delorme procedure had failed. An ultra-low anterior resection with a temporary defunctioning ileostomy was carried out with good postoperative results. This case illustrates the possibility of carrying out sphincter preserving surgery rather than an abdominoperineal resection in the treatment of this condition, which may be preferable for patients.

    AIM: To analyze the outcomes of laparoscopic ventral mesh rectopexy in the management of complete rectal prolapse (CRP) in North Indian patients with inherent bulky and redundant colon. METHODS: The study was conducted at a tertiary health care center of North India. Between January 2010 and October 2014, 15 patients who underwent laparoscopic ventral mesh repair for CRP, were evaluated in the present study. Perioperative outcomes, improvement in bowel dysfunction or appearance of new complications were documented from the hospital records maintained prospectively. RESULTS: Fifteen patients (9 female) with a median age of 50 years (range, 15-68) were included in the study. The median operative time was 200 min (range, 180-350 min) and the median post-operative stay was 4 d (range, 3-21 d). No operative mortality occurred. One patient with inadvertent small bowel injury required laparotomy on post-operative day 2. At a median follow-up of 22 mo (range, 4-54 mo), no prolapse recurrence was reported. No mesh-related complication was encountered. Wexner constipation score improved significantly from the preoperative value of 17 (range, 5-24) to 6 (range, 0-23) (P < 0.001) and the fecal incontinence severity index score from 24 (range, 0-53) to 2 (range, 0-53) (P = 0.007). No de novo constipation or fecal incontinence was recorded during the follow-up. On personal conversation, all patients expressed satisfaction with the outcome of their treatment. CONCLUSION: Our experience indicates that laparoscopic ventral mesh rectopexy is an effective surgical option for CRP in North Indian patients having a bulky redundant colon. PMID:27152139

    Genetic epidemiology, the study of genetic contributions to risk for disease, is an innovative area in medicine. While research in this arena has advanced in other disciplines, few genetic epidemiologic studies have been conducted in obstetrics and gynecology. It is crucial that we study the genetic susceptibility for issues in women’s health, as this information will shape the new frontier of “personalized medicine.” To date, preterm birth may be one of the best examples of genetic susceptibility in obstetrics and gynecology, but many areas are being evaluated including endometriosis, fibroids, polycystic ovarian syndrome and pelvic floor disorders. An essential component to genetic epidemiologic studies is to characterize, or “phenotype,” the disorder in order to identify genetic effects. Given the growing importance of genomics and genetic epidemiology, we discuss the importance of accurate phenotyping of clinical disorders and highlight critical considerations and opportunities in phenotyping, using pelvic organ prolapse as a clinical example.

    Ventral mesh rectopexy is an approach in the treatment of internal and external rectal prolapse and rectocele. Our aim was to assess whether robotic surgery confers any significant advantages over laparoscopy, and the associated complication rate. Two reviewers performed a literature search using MEDLINE and PubMed databases for studies comparing robotic versus laparoscopic surgery. Five prospective, non-randomised studies were identified and included. A total of 244 patients (101 robotic and 143 laparoscopic) were included in the analysis. Operative time was shorter with laparoscopic surgery, mean weighted difference 27.94 [confidence interval (CI) 19.30-36.57; p < 0.00001]. The conversion rate was not significantly different between groups. There was a trend towards a reduction in length of inpatient stay and early post-operative complications in the robotic group; however, these did not reach statistical significance. Recurrence rates were similar between groups (odds ratio 0.91, CI 0.32-2.63; p = 0.87). Functional results were comparable between groups. Early studies show that robotic ventral rectopexy is a safe option compared to the laparoscopic approach, with overall comparable results. There appeared to be a trend towards a reduction in length of inpatient stay and post-operative complications. These perceived benefits may offset the longer operative times and outlay costs. Larger randomised controlled trials are needed to further evaluate clinical value and cost-effectiveness.

  11. The pathophysiology of pelvic floor disorders: evidence from a histomorphologic study of the perineum and a mouse model of rectal prolapse

    The muscle changes related to pelvic floor disorders are poorly understood. We conducted an anatomical and histological study of the perineum of the normal mouse and of a transgenic mouse strain deficient in urokinase-type plasminogen activator (uPA−/−) that was previously reported to develop a high incidence of rectal prolapse. We could clearly identify the iliococcygeus (ILC) and pubococcygeus (PC) muscles and anal (SPA) and urethral (SPU) sphincters in male and female mice. The bulbocavernosus (BC), ischiocavernosus (ISC) and levator ani (LA) muscles could be found only in male mice. Histochemical analysis of the pelvic floor muscles revealed a majority of type IIA fibres. Rectal prolapses were observed only in male uPA−/− mice. The most obvious finding was an irreducible evagination of the rectal mucosa and a swelling of the entire perineal region corresponding to an irreducible hernia of the seminal vesicles through the pelvic outlet. The hernia caused stretching and thinning of the ISC, BC and LA. Myopathic damage, with degenerated and centronucleated myofibres, were observed in these muscles. The PC, ILC, SPA and SPU were not affected. This study provides an original description of a model of pelvic floor disorder and illustrates the differences existing between the perineum of humans and that of a quadruped species. In spite of these differences, the histopathologic changes observed in the pelvic floor muscles of uPA−/− mice with rectal prolapse suggest that prolonged muscular stretching causes a primary myopathic injury. This should be taken into account in the evaluation of pelvic floor disorders. PMID:11760891

    Solitary rectal ulcer syndrome (SRUS) is an uncommon benign disease, characterized by a combination of symptoms, clinical findings and histological abnormalities. Ulcers are only found in 40% of the patients; 20% of the patients have a solitary ulcer, and the rest of the lesions vary in shape and size, from hyperemic mucosa to broad-based polypoid. Men and women are affected equally, with a small predominance in women. SRUS has also been described in children and in the geriatric population. Clinical features include rectal bleeding, copious mucus discharge, prolonged excessive straining, perineal and abdominal pain, feeling of incomplete defecation, constipation, and rarely, rectal prolapse. This disease has well-described histopathological features such as obliteration of the lamina propria by fibrosis and smooth muscle fibers extending from a thickened muscularis mucosa to the lumen. Diffuse collage deposition in the lamina propria and abnormal smooth muscle fiber extensions are sensitive markers for differentiating SRUS from other conditions. However, the etiology remains obscure, and the condition is frequently associated with pelvic floor disorders. SRUS is difficult to treat, and various treatment strategies have been advocated, ranging from conservative management to a variety of surgical procedures. The aim of the present review is to summarize the clinical features, pathophysiology, diagnostic methods and treatment strategies associated with SRUS.

    Objective. To evaluate the clinical outcomes and urodynamic effects of tailored anterior transvaginal mesh surgery (ATVM) and tailored posterior transvaginal mesh surgery (PTVM). Methods. We developed ATVM for the simultaneous correction of cystocele and stress urinary incontinence and PTVM for the simultaneous correction of enterocoele, uterine prolapse, vaginal stump prolapse, and rectocele. Results. A total of 104 women enrolled. The median postsurgical follow-up was 25.5 months. The anatomic cure rate was 98.1% (102/104). Fifty-eight patients underwent urodynamic studies before and after surgeries. The pad weight decreased from 29.3 ± 43.1 to 6.4 ± 20.9 g at 3 months. Among the 20 patients with ATVM, 13 patients had objective stress urinary incontinence (SUI) at baseline while 8 patients came to have no demonstrated SUI (NDSUI), and 2 improved after surgery. Among the 38 patients who underwent ATVM and PTVM, 24 had objective SUI at baseline while 18 came to have NDSUI, and 2 improved after surgery. Mesh extrusion (n = 4), vaginal hematoma (n = 3), and voiding difficulty (n = 2) were noted postoperatively. Quality of life was substantially improved. Conclusions. Our findings document the advantages of these two novel pelvic reconstructive surgeries for pelvic organ prolapse, which had a positive impact on quality of life. ATVM surgery additionally provided an anti-incontinence effect. This clinical trial is registered at ClinicalTrials.gov (NCT02178735). PMID:26634203

    Objective Characterize pelvic floor symptom distress and impact, sexual function and quality of life in women who underwent rectal prolapse surgery. Methods Subjects undergoing rectal prolapse surgery from 2004–2009 completed questionnaires including the Pelvic Floor Distress Inventory, Pelvic Floor Impact Questionnaire, and the Prolapse/Urinary Incontinence Sexual Questionnaire. Baseline demographic, medical, and surgical characteristics were extracted by chart review. Demographic and clinic outcomes of women undergoing transperineal and abdominal approaches were compared. Wilcoxon rank-sum test was used for continuous variables and Fisher’s exact test for categorical measures. Results 45 were identified; two deceased at follow-up. 28/43 subjects (65.1%) responded to the questionnaires. Mean time from original procedure was 3.9 ± 3.1 years. No differences in median total Pelvic Floor Distress Inventory, Pelvic Floor Impact Questionnaire, and subscale scores, and Prolapse/Urinary Incontinence Sexual Questionnaire scores in women undergoing open rectopexy versus transperineal proctectomy were seen (all p>0.05). 26 (60%) participants answered the Prolapse/Urinary Incontinence Sexual Questionnaire, nine reported sexual activity within the last month. All underwent abdominal procedures. Conclusion There are few colorectal or other pelvic floor symptoms after rectal prolapse repair. Robust prospective studies are needed to more fully characterize and understand issues associated with rectal prolapse surgery in women. PMID:25379122

    Background Thyroid associated orbitopathy (TAO) comprises a spectrum of well-recognized clinical signs including exophthalmos, eyelid retraction, soft tissue swelling, ocular misalignment, keratopathy as well as a number of less common manifestations. Subconjunctival fat prolapse is a rare clinical condition occurring typically spontaneously in elderly patients with a mean age of 65–72 years. We describe subconjunctival prolapse of orbital fat as an uncommon clinical association of TAO. Materials and methods Observational study of six patients presenting with a subconjunctival protrusion under the lateral canthus in a series of 198 consecutive cases with TAO examined at a tertiary care referral center. Results A superotemporally located yellowish, very soft, freely mobile subconjunctival protrusion developed unilaterally in two and bilaterally in four patients with TAO (incidence 3.03%). It was one of the presenting manifestations of TAO in four of ten eyes studied and incited the diagnostic work-up for TAO in two of six patients in this series. Magnetic resonance imaging of the orbit indicated fat density in continuity with intraorbital fat in the area of protrusion. A male to female preponderance of 4:2 and an advanced mean age at onset of TAO is noteworthy for these six patients compared to the pool of 192 patients (64.8 versus 51.8 years, respectively, P=0.003) not bearing this sign. Conclusion Subconjunctival orbital fat prolapse, a clinically impressive age-related ocular lesion, may occasionally predominate amid other clinical manifestations of TAO. It is a nonspecific sign developing most commonly among patients with a relatively advanced age at presentation. Awareness of this association may alert to the diagnosis of thyroid orbitopathy and reassure the patient and physician as to the benign character of the lesion. PMID:28243072

  18. Clinically relevant study end points in rectal cancer.

    PubMed

    Fernandez-Martos, Carlos; Guerrero, Angel; Minsky, Bruce

    2012-01-01

    In rectal cancer currently there are no clearly validated early end points which can serve as surrogates for long-term clinical outcome such as local control and survival. However, the use of a variety of response rates (i.e. pathological complete response, downsizing the primary tumor, tumor regression grade (TRG), radiological response) as endpoints in early (phase II) clinical trials is common since objective response to therapy is an early indication of activity. Disease-free survival (DFS) has been proposed as the most appropriate end point in adjuvant trials and is one of the most frequently used in newer rectal cancer trials. Due to the devastating nature of local recurrence in locally advanced rectal cancer, local control (which is itself a subset of the overall DFS endpoint) is still considered an important endpoint. Recently, circumferential resection margin (CRM) has been proposed as novel early end point because the CRM status can account for effects on DFS and overall survival after chemoradiation, radiation (RT), or surgery alone. Consensus is needed to define the most appropriate end points in both early and phase III trials in locally advanced cancer.

  19. Pilot Study of a Clinical Pathway Implementation in Rectal Cancer

    Uña, Esther; López-Lara, Francisco

    2010-01-01

    Background: Rectal cancer is a highly prevalent disease which needs a multidisciplinary approach to be treated. The absence of specific protocols implies a significant and unjustifiable variability among the different professionals involved in this disease. The purpose is to develop a clinical pathway based on the analysis process and aims to reduce this variability and to reduce unnecessary costs. Methods: We created a multidisciplinary team with contributors from every clinical area involved in the diagnosis and treatment in this disease. We held periodic meetings to agree on a protocol based on the best available clinical practice guidelines. Once we had agreed on the protocol, we implemented its use as a standard in our institution. Every patient older than 18 years who was diagnosed with rectal cancer was considered a candidate to be treated via the pathway. Results: We evaluated 48 patients during the course of this study. Every parameter measured was improved after the implementation of the pathway, except the proportion of patients with 12 nodes or more analysed. The perception that our patients had about this project was very good. Conclusions: Clinical pathways are needed to improve the quality of health care. This kind of project helps reduce hospital costs and optimizes the use of limited resources. On the other hand, unexplained variability is also reduced, with consequent benefits for the patients.

    Purpose To determine the clinical impact of human leukocyte antigen (HLA) class I expression in irradiated and non-irradiated rectal carcinomas. Experimental design Tumor samples in tissue micro array format were collected from 1,135 patients. HLA class I expression was assessed after immunohistochemical staining with two antibodies (HCA2 and HC10). Results Tumors were split into two groups: (1) tumors with >50% of tumor cells expressing HLA class I (high) and (2) tumors with ≤50% of tumor cells expressing HLA class I (low). No difference in distribution or prognosis of HLA class I expression was found between irradiated and non-irradiated patients. Patients with low expression of HLA class I (15% of all patients) showed an independent significantly worse prognosis with regard to overall survival and disease-free survival. HLA class I expression had no effect on cancer-specific survival or recurrence-free survival. Conclusions Down-regulation of HLA class I in rectal cancer is associated with poor prognosis. In contrast to our results, previous reports on HLA class I expression in colorectal cancer described a large population of patients with HLA class I negative tumors, having a good prognosis. This difference might be explained by the fact that a large proportion of HLA negative colon tumors are microsatellite instable (MSI). MSI tumors are associated with a better prognosis than microsatellite stable (MSS). As rectal tumors are mainly MSS, our results suggest that it is both, oncogenic pathway and HLA class I expression, that dictates patient’s prognosis in colorectal cancer. Therefore, to prevent confounding in future prognostic analysis on the impact of HLA expression in colorectal tumors, separate analysis of MSI and MSS tumors should be performed. PMID:17874100

  1. Clinical application of multimodality imaging in radiotherapy treatment planning for rectal cancer.

    Radiotherapy plays an important role in the treatment of rectal cancer. Three-dimensional conformal radiotherapy and intensity-modulated radiotherapy are mainstay techniques of radiotherapy for rectal cancer. However, the success of these techniques is heavily reliant on accurate target delineation and treatment planning. Computed tomography simulation is a cornerstone of rectal cancer radiotherapy, but there are limitations, such as poor soft-tissue contrast between pelvic structures and partial volume effects. Magnetic resonance imaging and positron emission tomography (PET) can overcome these limitations and provide additional information for rectal cancer treatment planning. PET can also reduce the interobserver variation in the definition of rectal tumor volume. However, there is a long way to go before these image modalities are routinely used in the clinical setting. This review summarizes the most promising studies on clinical applications of multimodality imaging in target delineation and treatment planning for rectal cancer radiotherapy.

    The aim of the present study was to compare clinical and radiological findings when assessing posterior vaginal wall prolapse. Defecography can be used to complement the clinical evaluation in patients with posterior vaginal wall prolapse. Further development of the defecography technique, using contrast medium in the urinary bladder and intraperitoneally, have resulted in cystodefecoperitoneography (CDP). Thirty-eight women underwent clinical examination using the pelvic organ prolapse quantification system (POP-Q) followed by CDP. All patients answered a standardized bowel function questionnaire. Statistical analysis measuring correlation between POP-Q and CDP using Pearson's correlation coefficient (r) and Spearman's rank order correlation coefficient (rs) demonstrated a poor to moderate correlation, r=0.49 and rs=0.55. Although there was a strong association between large rectoceles (>3 cm) at CDP and symptoms of rectal emptying difficulties (p<0.001), severity and prevalence of bowel dysfunction showed poor coherence with clinical prolapse staging and findings at radiological imaging. Vaginal topography and POP-Q staging predict neither radiological size nor visceral involvement in posterior vaginal wall prolapse. Radiological evaluation may therefore be a useful complement in selected patients.

    Abstract Background: Testing women for urogenital Neisseria gonorrhoeae (GC) and Chlamydia trachomatis (CT) is common in sexually transmitted disease (STD) clinics. However, women may not be routinely tested for rectal GC/CT. This may lead to missed infections in women reporting anal intercourse (AI). Methods: This was a retrospective review of all women who underwent rectal GC/CT testing from August 2012 to June 2013 at an STD clinic in Columbus, Ohio. All women who reported AI in the last year had a rectal swab collected for GC/CT nucleic acid amplification testing (n=331). Using log-binomial regression models, we computed unadjusted and adjusted associations for demographic and behavioral factors associated with rectal GC/CT infection. Results: Participants (n=331) were 47% African-American, with median age of 29 years. Prevalence of rectal GC was 6%, rectal CT was 13%, and either rectal infection was 19%. Prevalence of urogenital GC and CT was 7% and 13% respectively. Among women with rectal GC, 14% tested negative for urogenital GC. Similarly, 14% of women with rectal CT tested negative for urogenital CT. In unadjusted analyses, there was increased rectal GC prevalence among women reporting sex in the last year with an injection drug user, with a person exchanging sex for drugs or money, with anonymous partners, and while intoxicated/high on alcohol or illicit drugs. After multivariable adjustment, no significant associations persisted, but a trend of increased rectal GC prevalence was observed for women <26 years of age (p=0.06) and those reporting sex while intoxicated/high on alcohol or drugs (p=0.05). For rectal CT, only age <26 years was associated with prevalent infection in unadjusted models; this association strengthened after multivariable adjustment (prevalence ratio: 6.03; 95% confidence interval: 2.29–15.90). Conclusion: Nearly one in five women who reported AI in the last year had rectal GC or CT infection. Urogenital testing alone would have

    During a survey of clinical rectal prolapse (RP) cases in the mouse population at MIT animal research facilities, a high incidence of RP in the lamellipodin knock-out strain, C57BL/6-Raph1tm1Fbg (Lpd-/-) was documented. Upon further investigation, the Lpd-/- colony was found to be infected with multiple endemic enterohepatic Helicobacter species (EHS). Lpd-/- mice, a transgenic mouse strain produced at MIT, have not previously shown a distinct immune phenotype and are not highly susceptible to other opportunistic infections. Predominantly male Lpd-/- mice with RP exhibited lesions consistent with invasive rectal carcinoma concomitant to clinically evident RP. Multiple inflammatory cytokines, CD11b+Gr1+ myeloid-derived suppressor cell (MDSC) populations, and epithelial cells positive for a DNA damage biomarker, H2AX, were elevated in affected tissue, supporting their role in the neoplastic process. An evaluation of Lpd-/- mice with RP compared to EHS-infected, but clinically normal (CN) Lpd-/- animals indicated that all of these mice exhibit some degree of lower bowel inflammation; however, mice with prolapses had significantly higher degree of focal lesions at the colo-rectal junction. When Helicobacter spp. infections were eliminated in Lpd-/- mice by embryo transfer rederivation, the disease phenotype was abrogated, implicating EHS as a contributing factor in the development of rectal carcinoma. Here we describe lesions in Lpd-/- male mice consistent with a focal inflammation-induced neoplastic transformation and propose this strain as a mouse model of rectal carcinoma. PMID:27045955

    Loop colostomy prolapse is associated with an impaired quality of life. Surgical treatment may sometimes be required for cases that cannot be closed by colon colostomy because of high-risk morbidities or advanced disease. We applied the Altimeter operation for patients with transverse loop colostomy. The Altemeier operation is therefore indicated for rectal prolapse. This technique involves a simple operation, which includes a circumferential incision through the full thickness of the outer and inner cylinder of the prolapsed limb, without incising the abdominal wall, and anastomosis with sutures using absorbable thread. We performed the Altemeier operation for three cases of loop stomal prolapse. Those patients demonstrated no postoperative complications (including obstruction, prolapse recurrence, or hernia). Our findings suggest that this procedure is useful as an optional surgical treatment for cases of transverse loop colostomy prolapse as a permanent measure in patients with high-risk morbidities or advanced disease.

    Solitary rectal ulcer syndrome (SRUS) is a rare, benign disorder in children that usually presents with rectal bleeding, constipation, mucous discharge, prolonged straining, tenesmus, lower abdominal pain, and localized pain in the perineal area. The underlying etiology is not well understood, but it is secondary to ischemic changes and trauma in the rectum associated with paradoxical contraction of the pelvic floor and the external anal sphincter muscles; rectal prolapse has also been implicated in the pathogenesis. This syndrome is diagnosed based on clinical symptoms and endoscopic and histological findings, but SRUS often goes unrecognized or is easily confused with other diseases such as inflammatory bowel disease, amoebiasis, malignancy, and other causes of rectal bleeding such as a juvenile polyps. SRUS should be suspected in patients experiencing rectal discharge of blood and mucus in addition to previous disorders of evacuation. We herein report six pediatric cases with SRUS.

    Regional hypoxia caused by accelerated cell proliferation and overgrowth is an important characteristic of neoplasm. Hypoxia can cause a series of changes in gene transcription and protein expression, thereby not only inducing tumor cell resistance to radiotherapy and chemotherapy but also promoting tumor invasion and metastasis. This study aimed to investigate the relationship between HIF-1α expression and cellular apoptosis, angiogenesis and clinical prognosis in rectal carcinoma. In 113 rectal carcinoma cases, cellular apoptosis was analyzed by the in situ terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) assay, whereas the levels of HIF-1α expression, VEGF expression, microvessel density (MVD) and lymphatic vessel density(LVD) were examined by immunohistochemical staining. HIF-1 expression was detected in 67 of 113 rectal carcinoma cases (59.3 %). A positive correlation was found among HIF-1α expression, cellular apoptosis and angiogenesis. The 5-year survival rate in the HIF-1α-negative group was significantly higher than that in the HIF-1α-positive group (81.34 % versus 50 %, P < 0.05). According to the Cox regression analysis, HIF-1α expression, VEGF expression and cellular apoptosis index were independent risk factors for clinical prognosis in rectal carcinoma. Aberrant HIF-1α expression correlates with apoptosis inhibition, angiogenesis and poor prognosis in rectal carcinoma.

    2016-01-01

    Ischemic mitral prolapse (IMP) is a pathologic entity encountered in about one-third among the patients undergoing surgery for ischemic mitral regurgitation (IMR). IMP is generally the result of a papillary muscle injury consequent to myocardial, but the recent literature is progressively unveiling a more complex pathogenesis. The mechanisms underlying its development regards the impairment of one or more components of the mitral apparatus, which comprises the annulus, the chordae tendineae, the papillary muscle and the left ventricular wall. IMP is not only a disorder of valvular function, but also entails coexistent aspects of a geometric disturbance of the mitral valve configuration and of the left ventricular function and dimension and a correct understanding of all these aspects is crucial to guide and tailor the correct therapeutic strategy to be adopted. Localization of prolapse, anatomic features of the prolapsed leaflets and the subvalvular apparatus should be carefully evaluated as also constituting the major determinants defining patient’s outcomes. This review will summarize our current understanding of the pathophysiology and clinical evidence on IMP with a particular focus on the surgical treatment. PMID:28149574

    Laparoscopic rectal surgery continues to be a challenging operation associated to a steep learning curve. Robotic surgical systems have dramatically changed minimally invasive surgery. Three-dimensional, magnified and stable view, articulated instruments, and reduction of physiologic tremors leading to superior dexterity and ergonomics. Therefore, robotic platforms could potentially address limitations of laparoscopic rectal surgery. It was aimed at reviewing current literature on short-term clinical and oncological (pathological) outcomes after robotic rectal cancer surgery in comparison with laparoscopic surgery. A systematic review was performed for the period 2002 to 2014. A total of 1776 patients with rectal cancer underwent minimally invasive robotic treatment in 32 studies. After robotic and laparoscopic approach to oncologic rectal surgery, respectively, mean operating time varied from 192-385 min, and from 158-297 min; mean estimated blood loss was between 33 and 283 mL, and between 127 and 300 mL; mean length of stay varied from 4-10 d; and from 6-15 d. Conversion after robotic rectal surgery varied from 0% to 9.4%, and from 0 to 22% after laparoscopy. There was no difference between robotic (0%-41.3%) and laparoscopic (5.5%-29.3%) surgery regarding morbidity and anastomotic complications (respectively, 0%-13.5%, and 0%-11.1%). Regarding immediate oncologic outcomes, respectively among robotic and laparoscopic cases, positive circumferential margins varied from 0% to 7.5%, and from 0% to 8.8%; the mean number of retrieved lymph nodes was between 10 and 20, and between 11 and 21; and the mean distal resection margin was from 0.8 to 4.7 cm, and from 1.9 to 4.5 cm. Robotic rectal cancer surgery is being undertaken by experienced surgeons. However, the quality of the assembled evidence does not support definite conclusions about most studies variables. Robotic rectal cancer surgery is associated to increased costs and operating time. It also seems to be

    Purpose To investigate whether preoperative chemoradiotherapy (PCRT) followed by local excision (LE) is feasible approach in clinical T2N0 rectal cancer patients. Materials and Methods Patients who received PCRT and LE because of clinical T2 rectal cancer within 7 cm from anal verge between January 2006 and June 2014 were retrospectively analyzed. LE was performed in case of a good clinical response after PCRT. Patients’ characteristics, treatment record, tumor recurrence, and treatment-related complications were reviewed at a median follow-up of 49 months. Results All patients received transanal excision or transanal minimally invasive surgery. Of 34 patients, 19 patients (55.9%) presented pathologic complete response (pCR). The 3-year local recurrence-free survival and disease free-survival were 100.0% and 97.1%, respectively. There was no recurrence among the patients with pCR. Except for 1 case of grade 4 enterovesical fistula, all other late complications were mild and self-limiting. Conclusion PCRT followed by an LE might be feasible as an alternative to total mesorectal excision in good responders with clinical T2N0 distal rectal cancer. PMID:27730804

    Atrial and ventricular arrhythmias have been reported with variable incidence in symptomatic patients with mitral valve prolapse (MVP). The role of clinical and echocardiographic parameters as predictors for arrhythmias still needs to be clarified. One hundred nineteen consecutive patients (56 women and 63 men, mean age 40 +/- 17 years) with echocardiographically diagnosed MVP were examined. A complete echocardiographic study (M-mode, two-dimensional, and Doppler) and 24-hour electrocardiographic monitoring were performed in all patients. Complex atrial arrhythmias (CAAs) included atrial couplets, atrial tachycardia, and paroxysmal or sustained atrial flutter or fibrillation. Complex ventricular arrhythmias (CVAs) included multiform ventricular premature contractions (VPCs), VPC couplets, and runs of three or more sequential VPCs (salvos of ventricular tachycardia). The relation between complex arrhythmias and clinical parameters (age and gender) and echocardiographic parameters (left atrial and left ventricular dimensions, anterior mitral leaflet thickness [AMLT], and presence and severity of mitral regurgitation) was evaluated by multiple logistic regression analysis. CAA were present in 14% of patients and CVA in 30%. According to multiple logistic modeling, CAA correlated separately in the univariate analysis with age, presence of MR, and left ventricular and left atrial diameters; age was the only independent predictor (p < 0.001). CVA, in the univariate analysis, correlated with age, female gender, left ventricular end-diastolic diameter, and AMLT; only female gender and AMLT were independent predictors in the multivariate analysis (p < 0.01). The incidence of mitral regurgitation (59%) was higher than expected in a general population of MVP patients.(ABSTRACT TRUNCATED AT 250 WORDS)

    CD133 and CD44 have been considered as markers for colorectal cancer stem cells (CSCs). The association of CD133 and CD44 expression with radiation has not been fully examined in rectal cancer. Both CD133 (PROM) and CD44 mRNA levels were measured in post-chemoradiotherapy (CRT) specimens of 52 rectal cancer patients using real-time RT-PCR and compared to clinicopathological variables and clinical outcome. Their protein levels were examined in the radiation-treated HT29 human colon cancer cell line. Post-CRT CD133 in residual cancer cells was significantly higher than matched pre-CRT CD133 in biopsy specimens (n=30). By contrast, CD44 was significantly lower in post-CRT specimens (P<0.01). CD133 was associated with distant recurrence after CRT followed by surgery (P<0.05). Patients with elevated CD133 in residual cancer cells showed poor disease-free survival (P<0.05). No significant association between post-CRT CD44 and clinical outcome was found. The in vitro study showed that CD133 protein was increased in a radiation dose-dependent manner, despite of the decreased number of clonogenic radiation-surviving cells. CD44 protein was decreased after irradiation. CD133, but not CD44, was increased in radiation-resistant surviving colon cancer cells. Post-CRT CD133 in residual cancer cells may predict metachronous distant recurrence and poor survival of rectal cancer patients after CRT.

    Pelvic organ prolapse is downward descent of female pelvic organs, including the bladder, uterus or post-hysterectomy vaginal cuff, and the small or large bowel, resulting in protrusion of the vagina, uterus, or both. Prolapse development is multifactorial, with vaginal child birth, advancing age, and increasing body-mass index as the most consistent risk factors. Vaginal delivery, hysterectomy, chronic straining, normal ageing, and abnormalities of connective tissue or connective-tissue repair predispose some women to disruption, stretching, or dysfunction of the levator ani complex, connective-tissue attachments of the vagina, or both, resulting in prolapse. Patients generally present with several complaints, including bladder, bowel, and pelvic symptoms; however, with the exception of vaginal bulging, none is specific to prolapse. Women with symptoms suggestive of prolapse should undergo a pelvic examination and medical history check. Radiographic assessment is usually unnecessary. Many women with pelvic organ prolapse are asymptomatic and do not need treatment. When prolapse is symptomatic, options include observation, pessary use, and surgery. Surgical strategies for prolapse can be categorised broadly by reconstructive and obliterative techniques. Reconstructive procedures can be done by either an abdominal or vaginal approach. Although no effective prevention strategy for prolapse has been identified, considerations include weight loss, reduction of heavy lifting, treatment of constipation, modification or reduction of obstetric risk factors, and pelvic-floor physical therapy.

    The management of rectal cancer remains an important clinical problem. Although there was been great progress in surgical management, the survival of patients with locally advanced disease has not improved significantly during the past decades. Preoperative staging and evaluation of the risk of recurrence may help in the choice of operation. It is difficult for clinicians to quantify reliably with digital examination the degree of fixation of the tumor, and they usually cannot distinguish nodal metastases except in advanced cases. The more frequent overstaging of small tumors within one quadrant of the rectum is a major drawback of digital examination. Computed tomography and magnetic resonance seems to underestimate the extension of rectal tumors, but both can be helpful in selecting patients with advanced tumors for whom preoperative adjuvant treatment is being considered. Endoluminal ultrasound is superior in staging tumors confined to the rectal wall, but is not the ideal tool for staging: the results are examiner dependent, the field of vision in depth is limited, and stricturing tumors cannot be passed by the ultrasound transducer. Imaging diagnostic attendibility confirms the preeminent role of intraoperative exploration in the assessment of neoplastic diffusion in order to plan a correct surgical treatment.

    Carbapenem-resistant Enterobacteriaceae (CRE) are emerging extremely drug-resistant pathogens; blaKPC is the predominant carbapenemase in Israel. Early detection of asymptomatic rectal carriers is important for infection control purposes. We aimed to determine who among newly identified CRE rectal carriers is prone to have a subsequent clinical specimen with CRE. A matched case-control study was conducted in a tertiary care teaching hospital in Israel. Cases with a primary positive CRE rectal test and subsequent CRE clinical specimens were matched in a 1:2 ratio with CRE rectal carriers who did not develop subsequent CRE clinical specimens (controls). Matching was based on calendar time of primary CRE isolation, whether the primary CRE isolation was ≤ 48 h or > 48 h after hospital admission, and time at risk to have a subsequent clinical specimen. Data were extracted from the patients' medical records and from the hospital's computerized database. One hundred and thirty-two newly identified CRE rectal carriers (44 cases, 88 controls) were included. The median time interval between screening and subsequent clinical specimens was 11 days (range, 3-27); 86% of the clinical specimens were classified as true infections. Independent predictors of subsequent CRE clinical specimens were: admission to the intensive care unit, having a central venous catheter, receipt of antibiotics, and diabetes mellitus. Identification of the risk factors for subsequent infections among CRE-colonized patients can be used to control modifiable risk factors and to direct empirical antimicrobial therapy when necessary.

    More than half the patients with rectal cancer present with locally advanced rectal disease at diagnosis with a high risk of recurrence. Preoperative chemoradiotherapy and standardized radical surgery with total mesorectal excision have been established as the 'gold standard' for treating these patients. Pathological staging using the ypTNM classification system to decide on adjuvant chemotherapy (ACT) is widely used in clinical practice, but the delivery of ACT is still controversial, as many discrepancies persist in the conclusions of different trials, due to heterogeneity of the inclusion criteria between studies, lack of statistical power, and variations in preoperative and adjuvant regimens. In 2014, a meta-analysis of four randomized phase-III trials (EORTC 22921, I-CNR-RT, PROCTOR-SCRIPT, CHRONICLE) failed to demonstrate any statistical efficacy of fluorouracil (5FU)-based ACT. Three recent randomized trials aimed to compare 5FU with 5FU plus oxaliplatin-based chemotherapy. Two of them (ADORE, CAO/ARO/AIO-04) appeared to find a disease-free survival benefit for patients treated with the combination therapy. Thus, while awaiting new data, it can be said that, as of 2015, patients with yp stage I tumors or histological complete response derived no benefit from adjuvant therapy. On the other hand, the FOLFOX chemotherapy regimen should be proposed for yp stage III patients, and may be considered for yp stage II tumors in fit patients with high-risk factors. Nevertheless, well-designed and sufficiently powered clinical trials dedicated to adjuvant treatments for rectal cancer remain justified in future to achieve a high level of proof in keeping with evidence-based medical standards.

    Purpose: Sacral insufficiency (SI) fractures can occur as a late side effect of pelvic radiation therapy. Our goal was to determine the incidence, risk factors, and clinical course of SI fractures in patients treated with preoperative chemoradiation for rectal cancer. Materials and Methods: Between 1989 and 2004, 562 patients with non-metastatic rectal adenocarcinoma were treated with preoperative chemoradiation followed by mesorectal excision. The median radiotherapy dose was 45 Gy. The hospital records and radiology reports of these patients were reviewed to identify those with pelvic fractures. Radiology images of patients with pelvic fractures were then reviewed to identify those with SI fractures. Results: Among the 562 patients, 15 had SI fractures. The 3-year actuarial rate of SI fractures was 3.1%. The median time to SI fractures was 17 months (range, 2-34 months). The risk of SI fractures was significantly higher in women compared to men (5.8% vs. 1.6%, p = 0.014), and in whites compared with non-whites (4% vs. 0%, p = 0.037). On multivariate analysis, gender independently predicted for the risk of SI fractures (hazard ratio, 3.25; p = 0.031). Documentation about the presence or absence of pain was available for 13 patients; of these 7 (54%) had symptoms requiring pain medications. The median duration of pain was 22 months. No patient required hospitalization or invasive intervention for pain control. Conclusions: SI fractures were uncommon in patients treated with preoperative chemoradiation for rectal cancer. The risk of SI fractures was significantly higher in women. Most cases of SI fractures can be managed conservatively with pain medications.

  1. Progress in the treatment of locally advanced clinically resectable rectal cancer.

    2011-12-01

    There have been significant developments in the adjuvant treatment of locally advanced clinically resectable (T3 and/or N+) rectal cancer. Postoperative systemic chemotherapy plus concurrent pelvic irradiation (chemoradiation) significantly improves local control and survival compared with surgery alone. The German Rectal Cancer Trial confirmed that when chemoradiation is delivered preoperatively there is a significant decrease in acute and late toxicity and a corresponding increase in local control and sphincter preservation. Despite these advances, controversies remain. Among these controversies are the role of short-course radiation, whether postoperative adjuvant chemotherapy is necessary for all patients, and if the type of surgery after chemoradiation can be modified based on tumor response. Are there more accurate imaging techniques and/or molecular markers to help identify patients with positive pelvic nodes with the goal of reducing the chance of overtreatment with preoperative therapy. Will more effective systemic agents both improve outcome and modify the need for pelvic irradiation? This review examines the advances in chemoradiation as well as addresses these and other opportunities for improvement.

    Formalin fixed and paraffin-embedded human tissue resected during cancer surgery is indispensable for diagnostic and therapeutic purposes and represents a vast and largely unexploited resource for research. Optical microscopy of such specimen is curtailed by the diffraction-limited resolution of conventional optical microscopy. To overcome this limitation, we used STED super-resolution microscopy enabling optical resolution well below the diffraction barrier. We visualized nanoscale protein distributions in sections of well-annotated paraffin-embedded human rectal cancer tissue stored in a clinical repository. Using antisera against several mitochondrial proteins, STED microscopy revealed distinct sub-mitochondrial protein distributions, suggesting a high level of structural preservation. Analysis of human tissues stored for up to 17 years demonstrated that these samples were still amenable for super-resolution microscopy. STED microscopy of sections of HER2 positive rectal adenocarcinoma revealed details in the surface and intracellular HER2 distribution that were blurred in the corresponding conventional images, demonstrating the potential of super-resolution microscopy to explore the thus far largely untapped nanoscale regime in tissues stored in biorepositories.

    The absolute bioavailability of hydromorphone was investigated in eight healthy male subjects by a cross-over design (with washout period of two weeks) after intravenous (2 mg), peroral (4 mg) and rectal (3 mg) administration of hydromorphone. The use of saliva hydromorphone concentrations as a noninvasive technique in pharmacokinetic evaluation was investigated, and the clinical effects after the three routes of administration were determined. Hydromorphone has an absolute bioavailability of 51.35 +/- 29.29% and 36.33 +/- 29.60% after peroral and rectal administration, respectively. More side effects were observed after intravenous administration of hydromorphone than after rectal or peroral dosing. The saliva sampling for the hydromorphone concentration was found to be a useful noninvasive technique for the estimation of the elimination half-life of hydromorphone.

    Background Mitral valve prolapse (MVP) is accompanied by mental disorders including anxiety, which has similar presentations as MVP. It is hypothesised that treatment of anxiety might reduce the symptoms of MVP. Objective The aim of this study was to assess the clinical and echocardiographic effects of fluoxetine administration in patients with MVP and anxiety. Methods This randomized clinical trial was conducted on patients with documented MVP and generalised anxiety disorder (GAD) who were referred to Mashhad University of Medical Sciences cardiology clinics, Mashhad, Iran in 2015. Subjects were randomly assigned to intervention group who received propranolol and fluoxetine (both at 10 mg/day) and control group who received 10 mg/day propranolol. Assessments included echocardiography and GAD-7 questionnaire and rating of chest pain, that were performed at baseline and then weekly for 4 weeks. Analysis was performed using the Mann-Whitney U test and Two-way Repeated Measures Analysis of Variance (ANOVA). Results Sixty patients (25 male/ 35 female) with a mean age of 22.9 ± 2.5 years were studied in two groups of intervention (n = 30) and control (n = 30). GAD score was significantly higher in the intervention group (17.37 ± 1.61) compared with the control group (14.17 ± 0.83) (p<0.001). No significant difference was observed for changes in left atrium diameter, mitral annular diameter, left ventricular diameter or ejection fraction (p>0.05). Pain severity was reduced significantly more in control group (3.27 ± 1.26) compared to intervention group (2.80 ± 0.85) after treatment (p<0.001). Conclusions This study revealed that the co-administration of fluoxetine and propranolol may not only have no effective in improving echocardiographic changes of MVP but may also aggravate subjective findings of patients with MVP and GAD. Trial registration The trial is registered at the Iranian Clinical Trial Registry (IRCT.ir) with the IRCT identification number IRCT

    Purpose Nelfinavir, a PI3-kinase pathway inhibitor, is a radiosensitizer which increases tumor blood flow in preclinical models. We conducted an early-phase study to demonstrate the safety of nelfinavir combined with hypofractionated radiotherapy (RT) and to develop biomarkers of tumor perfusion and radiosensitization for this combinatorial approach. Patients and Methods Ten patients with T3-4 N0-2 M1 rectal cancer received 7 days of oral nelfinavir (1250 mg bd) and a further 7 days of nelfinavir during pelvic RT (25 Gy/5 fractions/7 days). Perfusion CT (p-CT) and DCE-MRI scans were performed pre-treatment, after 7 days of nelfinavir and prior to last fraction of RT. Biopsies taken pre-treatment and 7 days after the last fraction of RT were analysed for tumor cell density (TCD). Results There were 3 drug-related grade 3 adverse events: diarrhea, rash, lymphopenia. On DCE-MRI, there was a mean 42% increase in median Ktrans, and a corresponding median 30% increase in mean blood flow on p-CT during RT in combination with nelfinavir. Median TCD decreased from 24.3% at baseline to 9.2% in biopsies taken 7 days after RT (P=0.01). Overall, 5/9 evaluable patients exhibited good tumor regression on MRI assessed by Tumor Regression Grade (mrTRG). Conclusions This is the first study to evaluate nelfinavir in combination with RT without concurrent chemotherapy. It has shown that nelfinavir-RT is well tolerated and is associated with increased blood flow to rectal tumors. The efficacy of nelfinavir-RT versus RT alone merits clinical evaluation, including measurement of tumor blood flow. PMID:26861457

    Purpose: To identify pretreatment clinical parameters that could predict pathologic tumor response to preoperative chemoradiotherapy (CRT) for rectal cancer. Methods and Materials: The study involved 351 patients who underwent preoperative CRT followed by surgery between October 2001 and July 2006. Tumor responses to preoperative CRT were assessed in terms of tumor downstaging and tumor regression. Statistical analyses were performed to identify clinical factors associated with pathologic tumor response. Results: Tumor downstaging (defined as ypT2 or less) was observed in 167 patients (47.6%), whereas tumor regression (defined as Dworak's Regression Grades 3 or 4) was observed in 103 patients (29.3%) and complete regression in 51 patients (14.5%). Multivariate analysis found that predictors of downstaging were pretreatment hemoglobin level (p = 0.045), cN0 classification (p < 0.001), and serum carcinoembryonic antigen (CEA) level (p < 0.001), that predictors of tumor regression were cN0 classification (p = 0.044) and CEA level (p < 0.001), and that the predictor of complete regression was CEA level (p = 0.004). Conclusions: The data suggest that pretreatment CEA level is the most important clinical predictor of pathologic tumor response. It may be of benefit in the selection of treatment options as well as the assessment of individual prognosis.

    To compare the efficacy of digital rectal examination and serum prostate specific antigen (PSA) in the early detection of prostate cancer, we conducted a prospective clinical trial at 6 university centers of 6,630 male volunteers 50 years old or older who underwent PSA determination (Hybritech Tandom-E or Tandem-R assays) and digital rectal examination. Quadrant biopsies were performed if the PSA level was greater than 4 μg./l. or digital rectal examination was suspicious, even if transrectal ultrasonography revealed no areas suspicious for cancer. The results showed that 15% of the men had a PSA level of greater than 4 μg./l., 15% had a suspicious digital rectal examination and 26% had suspicious findings on either or both tests. Of 1,167 biopsies performed cancer was detected in 264. PSA detected significantly more tumors (82%, 216 of 264 cancers) than digital rectal examination (55%, 146 of 264, p = 0.001). The cancer detection rate was 3.2% for digital rectal examination, 4.6% for PSA and 5.8% for the 2 methods combined. Positive predictive value was 32% for PSA and 21% for digital rectal examination. Of 160 patients who underwent radical prostatectomy and pathological staging 114 (71%) had organ confined cancer: PSA detected 85 (75%) and digital rectal examination detected 64 (56%, p = 0.003). Use of the 2 methods in combination increased detection of organ confined disease by 78% (50 of 64 cases) over digital rectal examination alone. If the performance of a biopsy would have required suspicious transrectal ultrasonography findings, nearly 40% of the tumors would have been missed. We conclude that the use of PSA in conjunction with digital rectal examination enhances early prostate cancer detection. Prostatic biopsy should be considered if either the PSA level is greater than 4 μg./l. or digital rectal examination is suspicious for cancer, even in the absence of abnormal transrectal ultrasonography findings.

    2015-06-01

    Pelvic organ prolapse is a common gynaecological problem. Surgical techniques to repair prolapse have been constantly evolving to reduce the recurrence of prolapse and need for reoperation. Grafts made of synthetic and biological materials became popular in the last decade as they were intended to provide extra support to native tissue repairs. However, serious complications related to use of synthetic meshes have been reported and there is increasing medico-legal concern about mesh use in prolapse surgery. Some mesh products already have been withdrawn from the market and the FDA has introduced stricter surveillance of new and existing products. Large randomized studies comparing mesh with non-mesh procedures are lacking which creates uncertainty for the surgeon and their patients.The small cohorts of the RCTs available with short follow-up periods just allow the conclusion that the mesh repair can be helpful in the short to medium term but unfortunately are not able to prove safety for all patients. In particular, current clinical reports cannot define for which indication what material may be superior compared to non-mesh repair.Quality control through long-term individual and national mesh registries is needed to keep a record of all surgeons using mesh and all devices being used, monitoring their effectiveness and safety data. Meshes with better biocompatibility designed specifically for use in vaginal surgery may provide superior clinical results, where the reduction of complications may allow a wider range of indications.

    OBJECTIVES: Pathological complete response has shown a better prognosis for patients with locally advanced rectal cancer after preoperative chemoradiotherapy. However, correlations between post-chemoradiotherapy clinical factors and pathologic complete response are not well confirmed. The aim of the current study was to identify post-chemoradiotherapy clinical factors that could serve as indicators of pathologic complete response in locally advanced rectal cancer. METHODS: This study retrospectively analyzed 544 consecutive patients with locally advanced rectal cancer treated at Sun Yat-sen University Cancer Center from December 2003 to June 2014. All patients received preoperative chemoradiotherapy followed by surgery. Univariate and multivariate regression analyses were performed to identify post-chemoradiotherapy clinical factors that are significant indicators of pathologic complete response. RESULTS: In this study, 126 of 544 patients (23.2%) achieved pathological complete response. In multivariate analyses, increased pathological complete response rate was significantly associated with the following factors: post-chemoradiotherapy clinical T stage 0-2 (odds ratio=2.098, 95% confidence interval=1.023-4.304, p=0.043), post-chemoradiotherapy clinical N stage 0 (odds ratio=2.011, 95% confidence interval=1.264-3.201, p=0.003), interval from completion of preoperative chemoradiotherapy to surgery of >7 weeks (odds ratio=1.795, 95% confidence interval=1.151-2.801, p=0.010) and post-chemoradiotherapy carcinoembryonic antigen ≤2 ng/ml (odds ratio=1.579, 95% confidence interval=1.026-2.432, p=0.038). CONCLUSIONS: Post-chemoradiotherapy clinical T stage 0-2, post-chemoradiotherapy clinical N stage 0, interval from completion of chemoradiotherapy to surgery of >7 weeks and post-chemoradiotherapy carcinoembryonic antigen ≤2 ng/ml were independent clinical indicators for pathological complete response. These findings demonstrate that post-chemoradiotherapy clinical

    Extramural venous invasion (EMVI) is associated with a poor prognosis and a poor overall survival rate in rectal cancer. It can independently predict local and distant tumor recurrences. Preoperative EMVI detection in rectal cancer is useful for determining the treatment strategy. EMVI status is beneficial for the post-treatment evaluation and analysis of rectal cancer. Magnetic resonance imaging (MRI) is a non-invasive diagnostic modality with no radiation effects. High-resolution MRI can detect EMVI with high accuracy. In addition, MRI results are equal to or even better than pathological results in the detection of medium to large EMVI in rectal cancer. MRI-detected EMVI (mrEMVI) can be used as a potential biomarker that facilitates treatment methods. This review highlights the importance of MRI before and after rectal cancer treatment. In addition, we analyze the prognostic correlation between mrEMVI and circulating tumor cells (CTC) in rectal cancer. This article may help shed light on the significance of mrEMVI.

    Summary: Pelvic organ prolapse suspension (POPS) is a recent surgical procedure for one-stage treatment of multiorgan female pelvic prolapse. This study evaluates the preliminary results of laparoscopic POPS in 54 women with a mean age of 55.2 and a BMI of 28.3. Patients underwent at the same time stapled transanal rectal resection (STARR) to correct the residual rectal prolapse. We had no relapses and the preliminary results were excellent. We evaluated the patients after 1 year follow-up and we confirmed the validity of our treatment. The technique is simplier than traditional treatments with an important reduction or completely disappearance of the pre-operative symptomatology. PMID:23837949

    Purpose: To study the impact of clinical predisposing factors on rectal normal tissue complication probability modeling using the updated results of the Dutch prostate dose-escalation trial. Methods and Materials: Toxicity data of 512 patients (conformally treated to 68 Gy [n = 284] and 78 Gy [n = 228]) with complete follow-up at 3 years after radiotherapy were studied. Scored end points were rectal bleeding, high stool frequency, and fecal incontinence. Two traditional dose-based models (Lyman-Kutcher-Burman (LKB) and Relative Seriality (RS) and a logistic model were fitted using a maximum likelihood approach. Furthermore, these model fits were improved by including the most significant clinical factors. The area under the receiver operating characteristic curve (AUC) was used to compare the discriminating ability of all fits. Results: Including clinical factors significantly increased the predictive power of the models for all end points. In the optimal LKB, RS, and logistic models for rectal bleeding and fecal incontinence, the first significant (p = 0.011-0.013) clinical factor was 'previous abdominal surgery.' As second significant (p = 0.012-0.016) factor, 'cardiac history' was included in all three rectal bleeding fits, whereas including 'diabetes' was significant (p = 0.039-0.048) in fecal incontinence modeling but only in the LKB and logistic models. High stool frequency fits only benefitted significantly (p = 0.003-0.006) from the inclusion of the baseline toxicity score. For all models rectal bleeding fits had the highest AUC (0.77) where it was 0.63 and 0.68 for high stool frequency and fecal incontinence, respectively. LKB and logistic model fits resulted in similar values for the volume parameter. The steepness parameter was somewhat higher in the logistic model, also resulting in a slightly lower D{sub 50}. Anal wall DVHs were used for fecal incontinence, whereas anorectal wall dose best described the other two endpoints. Conclusions: Comparable

    Objective. This study aims to compare clinical outcomes using the Perigee versus Elevate anterior devices for the treatment of pelvic organ prolapse (POP). Study Design. One hundred and forty-one women with POP stages II to IV were scheduled for either Perigee (n = 91) or Elevate anterior device (n = 50). Preoperative and postoperative assessments included pelvic examination, urodynamic study, and a personal interview about quality of life and urinary symptoms. Results. Despite postoperative point C of Elevate group being significantly deeper than the Perigee group (median: −7.5 versus −6; P < 0.01), the 1-year success rates for two groups were comparable (P > 0.05). Apart from urgency incontinence, women with advanced POP experienced significant resolution of irritating and obstructive symptoms after both procedures (P < 0.05), generating the improvement in postoperative scores of Urogenital Distress Inventory (UDI-6) and Incontinence Impact Questionnaire (IIQ-7) (P < 0.01). On urodynamics, only the residual urine decreased significantly following these two procedures (P < 0.05). Women undergoing Perigee mesh experienced significantly higher visual analogue scale (VAS) scores and vaginal extrusion rates compared with the Elevate anterior procedure (P < 0.05). Conclusions. With comparable success rates, the Elevate procedure has advantages over the Perigee surgery with lower extrusion rate and postoperative day 1 VAS scores. PMID:25893193

    The role of the surgical intervention is decisive in treating colorectal tumors. The neo-adjuvant radio-chemotherapy has improved the efficacy of the treatment of advanced rectum tumors. In order to decrease the size and stage of advanced rectal carcinoma and to increase the rate of resecability, we introduced neoadjuvant radio-chemotherapy. We carried out neo-adjuvant and surgical treatment in case of 67 patients with rectal adenocarcinoma (T 2-4 N 1-2 M 0 ) between June 1, 2005 and July 31, 2008. The average age of the patients was 61.2 years, the division according to sex was 44 males/23 females. Regarding the local stage of the rectal process or the proximity to the sphincter, we applied radio-chemotherapy (radiotherapy 25 times altogether 45 Gy and on the first and last week for 5-5 days they received 350 mg/m 2 /day 5-FU and 20 mg/m 2 /day leucovorin chemotherapy, recently complemented with 3 x 1.8 Gy advanced boost radiation aiming at the macroscopic tumor site with security zone). Patients underwent surgery 8 weeks on average after restaging examinations. Thirty-eight patients underwent anterior rectal resection with double stapler procedure; there were 18 abdominoperineal rectal extirpations, 7 Hartmann operations and 4 per annum excisions. Compared to the preoperative staging, the histological evaluation of the resected specimens showed total remission (pT 0 N 0 ) in 11% and partial remission in 43%. The morbidity necessitating reoperation was 5.9%, without mortality and suture insufficiency. The long-term neo-adjuvant oncological treatment led to down-staging of rectal tumors in most cases and increased the resecability and rate of resection operations.

    Purpose: To evaluate the extent of distal intramural spread (DIS) after preoperative radiotherapy for rectal cancer. Methods and Materials: A total of 316 patients with T{sub 3-4} primary resectable rectal cancer were randomized to receive either preoperative 5x5 Gy radiation with immediate surgery or chemoradiation (50.4 Gy, 1.8 Gy per fraction plus boluses of 5-fluorouracil and leucovorin) with delayed surgery. The slides of the 106 patients who received short-course radiation and of the 86 who received chemoradiation were available for central microscopic evaluation of DIS. Results: The length of DIS did not differ significantly (p = 0.64) between the short-course group and the chemoradiation group and was 0 in 47% vs. 49%; 1 to 5 mm in 41% vs. 42%; 6 to 10 mm in 8% vs. 9%, and greater than 10 mm in 4% vs. 0, respectively. Among the 11 clinically complete responders, DIS was found 1 to 5 mm from the microscopically detected ulceration of the mucosa in 5 patients. The discontinuous DIS was more frequent in the chemoradiation group as compared with the short-course group (i.e., 57% vs. 16% of cases, p < 0.001). Conclusions: Approximately 1 out of 10 advanced rectal cancers after preoperative radiotherapy or radiochemotherapy was characterized by DIS of over 5 mm. No significant difference was seen in the length of DIS between the 2 groups.

    Background The benefits of adjuvant radiotherapy in rectal carcinoma are well known. However, there is still considerable uncertainty about the optimal radiation treatment. There is an ongoing debate about the choice between very short treatments immediately followed by surgical resection and prolonged treatments with delayed surgery. In this paper, we describe an interim analysis of a non-controlled clinical trial in which radiotherapy delivered with intermediate dose/duration was followed by surgery after about 2 weeks to improve local control and survival after curative radiosurgery for cT3 low/middle rectal cancer. Methods Preoperative radiotherapy (36 Gy in 3 weeks) was delivered in 248 consecutive patients with cT3NxM0 rectal adenocarcinoma within 10 cm from the anal verge, followed by surgery within the third week after treatment completion. Results 166 patients (66.94%) underwent anterior resection, 80 patients (32.26%) the Miles' procedure and 2 patients (0.8%) the Hartmann's procedure. Local resectability rate was 99.6%, with 226 curative-intent resections. The overall rate of complications was 27.4%. 5-year oncologic outcomes were evaluated on 223 patients. The median follow-up time was 8.9 years (range 5-17.4 years); local recurrence (LR) rate and distal recurrence (DR) rate after 5 years were 6.28% and 21.97%, respectively. Overall survival was 74.2%; disease free survival was 73.5%; local control was 93.4 % and metastasis-free survival was 82.1%. Conclusions preoperative radiotherapy with intermediate dose/duration and interval between radiotherapy and surgery achieves high local control in patients with cT3NxM0 rectal cancer, and high DR rate seems to be the major limitation to improved survival.

    A man evaluated for disabling chest pain was found to have isolated anatomically corrected transposition of the great vessels. Angiography demonstrated right and left atrioventricular (A-V) valve prolapse and normal coronary arteries. Atrial pacing produced chest pain, ischemic electrocardiographic changes, abnormal myocardial lactate metabolism and marked elevation of the left ventricular end-diastolic pressure; all of these changes returned to normal on termination of pacing. The association of corrected transposition and bilateral A-V valve prolapse and the possible causes of myocardial ischemia in this patient are discussed.

    Colostomy prolapse is a frequently seen complication of transverse colostomy. In one child with recurrent stoma prolapse, we performed a loop-to-loop fixation and peritoneal tethering laparoscopically. No prolapse had recurred at follow-up. Laparoscopic repair of transverse colostomy prolapse seems to be a less invasive method than other techniques.

    Rectal cancer is the second most common cancer in large intestine. The prevalence and the number of young patients diagnosed with rectal cancer have made it as one of the major health problems in the world. With regard to the improved access to and use of modern screening tools, a number of new cases are diagnosed each year. Considering the location of the rectum and its adjacent organs, management and treatment of rectal tumor is different from tumors located in other parts of the gastrointestinal tract or even the colon. In this article, we will review the current updates on rectal cancer including epidemiology, risk factors, clinical presentations, screening, and staging. Diagnostic methods and latest treatment modalities and approaches will also be discussed in detail. PMID:26034724

    Preoperative chemoradiotherapy is worldwide accepted as a standard treatment for locally advanced rectal cancer. Current standard of treatment includes administration of ionizing radiation for 45-50.4 Gy in 25-28 fractions associated with 5-fluorouracil administration during radiation therapy. Unfortunately, 40% of patients have a poor or absent response and novel predictive biomarkers are demanding. For the first time, we apply a novel peptidomic methodology and analysis in rectal cancer patients treated with preoperative chemoradiotherapy. Circulating peptides (Molecular Weight <3 kDa) have been harvested from patients' plasma (n = 33) using nanoporous silica chip and analyzed by Matrix-Assisted Laser Desorption/Ionization-Time of Flight mass spectrometer. Peptides fingerprint has been compared between responders and non-responders. Random Forest classification selected three peptides at m/z 1082.552, 1098.537, and 1104.538 that were able to correctly discriminate between responders (n = 16) and non-responders (n = 17) before therapy (T0) providing an overall accuracy of 86% and an area under the receiver operating characteristic (ROC) curve of 0.92. In conclusion, the nanoporous silica chip coupled to mass spectrometry method was found to be a realistic method for plasma-based peptide analysis and we provide the first list of predictive circulating biomarker peptides in rectal cancer patients underwent preoperative chemoradiotherapy.

    Introduction: Physicians frequently deal with procedures which require sedation of pediatric patients. Laceration repair is one of them. No study has been performed regarding the comparison between induction of sedation with sodium thiopental and ketamine in laceration repair. Therefore, the present study was aimed to comparison of induced sedation by rectal sodium thiopental and muscular injection of hydrochloride ketamine in pediatric patients need laceration repair. Methods: The presented study is a single-blinded clinical trial performed through 2013 to 2014 in Ayatollah Kashani and Alzahra Hospitals, Isfahan, Iran. Patients from 3 months to 14 years, needed sedation for laceration repair, were entered. Patients were sequentially evaluated and randomly categorized in two groups of hydrochloride ketamine with dose of 2-4 milligram per kilogram and sodium thiopental with dose of 25 milligram per kilogram. Demographic data and vital signs before drug administration and after induction of sedation, Ramsey score, time to onset of action, and sedation recovery time were evaluated. Chi-squared, Mann-Whitney, and Non-parametric analysis of covariance tests were used. P<0.05 was considered as a significant level. Results: In this study 60 pediatric patients were entered. 30 patients with mean age of 42.8±18.82 months were received sodium thiopental and the rest with mean age of 30.08±16.88 months given ketamine. Mann-Whitney test was showed that time to onset of action in sodium thiopental group (28.23±5.18 minutes) was significantly higher than ketamine (7.77±4.13 minutes), (p<0.001). The sedation recovery time in ketamine group (29.83±7.70) was higher than sodium thiopental. Depth of sedation had no significant difference between two groups based on Ramsey score (p=0.87). No significant difference was seen between two groups in the respiratory rate (df=1, 58; F=0.002; P=0.96) and heart rate (df=1, 58; F=0.98; P=0.33). However, arterial oxygen saturation level (df

    AIM: To investigate control of two different types of massive presacral bleeding according to the anatomy of the presacral venous system. METHODS: A retrospective review was performed in 1628 patients with middle or low rectal carcinoma who were treated surgically in the Department of Colorectal Surgery, Changhai Hospital, Shanghai, China from January 2008 to December 2012. In four of these patients, the presacral venous plexus (n = 2) or basivertebral veins (n = 2) were injured with massive presacral bleeding during mobilization of the rectum. The first two patients with low rectal carcinoma were operated upon by a junior associate professor and the source of bleeding was the presacral venous plexus. The other two patients with recurrent rectal carcinoma were both women and the source of bleeding was the basivertebral veins. RESULTS: Two different techniques were used to control the bleeding. In the first two patients with massive bleeding from the presacral venous plexus, we used suture ligation around the venous plexus in the area with intact presacral fascia that communicated with the site of bleeding (surrounding suture ligation). In the second two patients with massive bleeding from the basivertebral veins, the pelvis was packed with gauze, which resulted in recurrent bleeding as soon as it was removed. Following this, we used electrocautery applied through one epiploic appendix pressed with a long Kelly clamp over the bleeding sacral neural foramen where was felt like a pit Electrocautery adjusted to the highest setting was then applied to the clamp to “weld” closed the bleeding point. Postoperatively, the blood loss was minimal and the drain tube was removed on days 4-7. CONCLUSION: Surrounding suture ligation and epiploic appendices welding are effective techniques for controlling massive presacral bleeding from presacral venous plexus and sacral neural foramen, respectively.

    Introduction: The aim of the study was to evaluate the safety and feasibility of stapled transanal procedures performed by a 36 mm stapling device, the so-called TST36 stapler. Methods: From September 2013 to June 2014 a prospective observational study was carried out by 8 proctology centers in Germany. The Cleveland Clinic Incontinence Score (CCIS) for incontinence and the Altomare ODS score were determined preoperatively. Follow-up examinations were performed after 14 days, one month and 6 months, at this time both scores were reevaluated. Results: 110 consecutive patients (71 women, 39 men) with a mean age of 59.7 years (±13.8 years) were included in the study. The eight participating institutes entered 3 to 31 patients each into the study. The indication for surgery was an advanced hemorrhoidal disease in 55 patients and ODS with rectal intussusception or rectocele in 55 patients. Mechanical problems with stapler introduction occurred in 22 cases (20%) and a partial stapleline dehiscence in 4 cases (3.6%). Additional stitches for bleeding from stapleline were necessary in 86 patients (78.2%). Reintervention was necessary for bleeding 7 times (6.3%). Severe complications during follow-up were stapleline dehiscence in one case and recurrent hemorrhoidal prolapse in 5 cases (4.5%). Altomare ODS score and CCIS improved significantly after surgery. Conclusions: Despite a notable complication rate during surgery and the postoperative period, the TST36 can be considered as an effective tool for low rectal stapling for anorectal prolapse causing hemorrhoids or obstructed defecation.

    Acute and chronic renal failure secondary to bilateral severe hydroureteronephrosis is a rare sequela of uterine prolapse. We report a case of neglected complete uterine prolapse in a 72-year-old patient resulting in bilateral hydroureter, hydronephrosis, and chronic renal failure. In an attempt to diminish the ureteral obstruction a vaginal pessary was used to reduce the uterine prolapse. Finally, surgical repair of prolapse by means of a vaginal hysterectomy was performed. In conclusion, all patients presenting with complete uterine prolapse should be screened to exclude urinary tract obstruction. If present, obstructive uropathy should be relieved by the reduction or repair of the prolapse before irreversible renal damage occurs.

  11. Prospective evaluation of a hydrogel spacer for rectal separation in dose-escalated intensity-modulated radiotherapy for clinically localized prostate cancer

    PubMed Central

    2013-01-01

    Background As dose-escalation in prostate cancer radiotherapy improves cure rates, a major concern is rectal toxicity. We prospectively assessed an innovative approach of hydrogel injection between prostate and rectum to reduce the radiation dose to the rectum and thus side effects in dose-escalated prostate radiotherapy. Methods Acute toxicity and planning parameters were prospectively evaluated in patients with T1-2 N0 M0 prostate cancer receiving dose-escalated radiotherapy after injection of a hydrogel spacer. Before and after hydrogel injection, we performed MRI scans for anatomical assessment of rectal separation. Radiotherapy was planned and administered to 78 Gy in 39 fractions. Results From eleven patients scheduled for spacer injection the procedure could be performed in ten. In one patient hydrodissection of the Denonvillier space was not possible. Radiation treatment planning showed low rectal doses despite dose-escalation to the target. In accordance with this, acute rectal toxicity was mild without grade 2 events and there was complete resolution within four to twelve weeks. Conclusions This prospective study suggests that hydrogel injection is feasible and may prevent rectal toxicity in dose-escalated radiotherapy of prostate cancer. Further evaluation is necessary including the definition of patients who might benefit from this approach. Trial registration: German Clinical Trials Register DRKS00003273. PMID:23336502

    Purpose: To investigate potential prognostic factors, including hemoglobin levels before and during radiotherapy, for associations with survival and local control in patients with unirradiated locally recurrent rectal cancer. Patients and Methods: Ten potential prognostic factors were investigated in 94 patients receiving radiotherapy for recurrent rectal cancer: age ({<=}68 vs. {>=}69 years), gender, Eastern Cooperative Oncology Group performance status (0-1 vs. 2-3), American Joint Committee on Cancer (AJCC) stage ({<=}II vs. III vs. IV), grading (G1-2 vs. G3), surgery, administration of chemotherapy, radiation dose (equivalent dose in 2-Gy fractions: {<=}50 vs. >50 Gy), and hemoglobin levels before (<12 vs. {>=}12 g/dL) and during (majority of levels: <12 vs. {>=}12 g/dL) radiotherapy. Multivariate analyses were performed, including hemoglobin levels, either before or during radiotherapy (not both) because these are confounding variables. Results: Improved survival was associated with better performance status (p < 0.001), lower AJCC stage (p = 0.023), surgery (p = 0.011), chemotherapy (p = 0.003), and hemoglobin levels {>=}12 g/dL both before (p = 0.031) and during (p < 0.001) radiotherapy. On multivariate analyses, performance status, AJCC stage, and hemoglobin levels during radiotherapy maintained significance. Improved local control was associated with better performance status (p = 0.040), lower AJCC stage (p = 0.010), lower grading (p = 0.012), surgery (p < 0.001), chemotherapy (p < 0.001), and hemoglobin levels {>=}12 g/dL before (p < 0.001) and during (p < 0.001) radiotherapy. On multivariate analyses, chemotherapy, grading, and hemoglobin levels before and during radiotherapy remained significant. Subgroup analyses of the patients having surgery demonstrated the extent of resection to be significantly associated with local control (p = 0.011) but not with survival (p = 0.45).

    Uterine prolapse during pregnancy is an uncommon condition. It can cause preterm labor, spontaneous abortion, fetal demise, maternal urinary complication, maternal sepsis and death. We report the case of uterine prolapse in a 32-year-old healthy primigravid woman. She had no risk factors associated with uterine prolapse. She was conservatively treated, resulting in a successful vaginal delivery. This report is a very rare case of uterine prolapse in a young healthy primigravid woman, resulting in a successful vaginal delivery. PMID:27200317

    Vancomycin-resistant enterococci (VRE) in healthy people and in food-producing animals seems to be quite common in Europe. The existence of this community reservoir of VRE has been associated with the massive use of avoparcin in animal husbandry. Eight years after the avoparcin ban in Europe, we investigated the incidence of VanA enterococci, their resistance patterns, and the mobility of their glycopeptide-resistance determinants in a sampling of animal rectal swabs and clinical specimens. A total of 259 enterococci isolated from equine, swine, and clinical samples were subcultured on KF-streptococcus agar (Difco Laboratories, Detroit, MI) supplemented with vancomycin and teicoplanin; 7 (6.7%), 10 (16%), and 8 (8.6%) respectively were found to be glycopeptides resistant (VanA phenotype). Slight differences in antimicrobial resistance patterns resulted among VRE recovered from the different sources. Polymerase chain reaction amplification demonstrated the presence of the vanA gene cluster and its extrachromosomal location in VRE plasmid DNA. VanA resistance was transferred in 7 out of 25 mating experiments, 4 with clinical, 2 with swine, and only 1 with equine donors. The conjugative plasmids of animal strains showed a high homology in the restriction profiles, unlike plasmids of clinical microrganisms. Our observations confirmed the possible horizontal transfer of VanA plasmids across different strains and, consequently, the diffusion of the vancomycin-resistance determinants.

    Occasionally, patients with locally advanced rectal adenocarcinoma who receive preoperative chemoradiotherapy (CRT) show acellular mucin in resection specimens that had shown pathologic complete response (pCR), but the clinical and prognostic significance of this finding has been controversial. This study analyzed data from 217 consecutive patients showing pCR to preoperative CRT followed by resection to evaluate the clinicopathologic features and prognostic significance of acellular mucin. Patients were categorized according to the presence of acellular mucin, as identified by pathologic analysis. The clinicopathologic findings and oncologic results were compared. Acellular mucins were identified in 35 (16.1%) of 217 pCR patients. Acellular mucins were found predominantly in male patients (20.8% vs. 9.8%, P=0.039) and in those with mucinous/signet ring cell differentiation (66.7% vs. 15.1%, P=0.008). The presence of acellular mucin was more frequent in patients with a shorter (<42 d) CRT-operation interval (22.6% vs. 10.3%, P=0.017). With a mean follow-up of 41 months (range, 2 to 119 mo), the 3-year overall survival (96.8% with mucin vs. 95.9% without mucin, P=0.314) and the 3-year disease-free survival (97.0% with mucin vs. 93.0% without mucin, P=0.131) did not differ between the groups. The presence of acellular mucin in rectal cancer patients showing pCR to preoperative CRT is associated with male sex and mucinous differentiation and does not have a significant impact on oncologic outcomes. Acellular mucins are also associated with the CRT-operation interval as a phenomenon of time-dependent response to CRT.

    The present study aimed to evaluate whether preoperative chemoradiotherapy (CRT) has any adverse effects on laparoscopic surgery (LS) for locally advanced low rectal cancer (LARC). The study was performed at the Osaka Medical College Hospital, and included patients who were operated on between July 2006 and December 2013. The short-term outcomes in 156 patients who underwent surgery for LARC following CRT were evaluated, of whom 152 underwent LS. Among the patients who were followed for >40 months, 77 patients (the CRT group) were compared with 39 patients who underwent LS without CRT (the surgery-alone group) for long-term outcomes. The total number of patients who received sphincter-preserving surgery was 74%. No positive longitudinal resection margins were identified, and only 1.3% had identifiable positive circumferential resection margins. The complication rate was 14%, and no serious complications occurred. There were no significant differences between the CRT and the surgery-alone groups in terms of the 5-year relapse-free survival rate (70.1 vs. 61.5%; P=0.81) or the 5-year overall survival rate (88.3 vs. 69.2%; P=0.06). However, the 5-year local recurrence-free survival rate was significantly improved in the CRT group patients (96.1 vs. 79.5%; P=0.009). In conclusion, our results have demonstrated that LS with preoperative CRT appears to be feasible and safe, and may have beneficial effects on local recurrence. PMID:28123724

    Retained rectal foreign bodies are most commonly seen in homosexuals and after assault. A few have been reported after self-treatment of anorectal conditions and prostatic massage. Harmful traditional medical practices have been reported in many communities in Africa but therapeutic anal insertion of foreign bodies for the management of haemorrhoids is rare. We present a patient with features of peritonitis following insertion of a wine bottle into his rectum in an attempt to manage his prolapsed haemorrhoids.

    Procedure for prolapsed haemorrhoids (PPH) is a popular treatment of haemorrhoids. PPH has the advantages of a shorter operation time, minor degree of postoperative pain, shorter hospital stay and quicker recovery but may be followed by several postoperative complications. Rectal bleeding, acute pain, chronic pain, rectovaginal fistula, complete rectal obliteration, rectal stenosis, rectal pocket, tenesmus, faecal urgency, faecal incontinence, rectal perforation, pelvic sepsis and rectal haematoma have all been reported as postoperative complications of PPH. Additionally, one rare complication of the procedure is intra-abdominal bleeding. There are a few case reports describing intra-abdominal bleeding after the procedure. We report a case of a 26-year-old man who developed severe intra-abdominal and retroperitoneal haemorrhage after PPH. The diagnosis was made on the second postoperative day by CT of the abdomen and pelvis. The patient was treated conservatively and had an uneventful recovery.

    Background The aim of this study is to analyse the pooled results of intraoperative electron beam radiotherapy (IOERT) containing multimodality treatment of locally advanced T4 rectal cancer, initially unresectable for cure, from the Mayo Clinic, Rochester, USA (MCR) and Catharina Hospital, Eindhoven, The Netherlands (CHE), both major referral centers for locally advanced rectal cancer. A rectal tumor is called locally unresectable for cure if after full clinical work-up infiltration into the surrounding structures or organs has been demonstrated, which would result in positive surgical margins if resection was the initial component of treatment. This was the reason to refer these patients to the IOERT program of one of the centers. Methods In the period from 1981 to 2010, 417 patients with locally unresectable T4 rectal carcinomas at initial presentation were treated with multimodality treatment including IOERT at either one of the two centres. The preferred treatment approach was preoperative (chemo) radiation and intended radical surgery combined with IOERT. Risk factors for local recurrence (LR), cancer specific survival, disease free survival and distant metastases (DM) were assessed. Results A total of 306 patients (73%) underwent a R0 resection. LRs and metastases occurred more frequently after an R1-2 resection (P<0.001 and P<0.001 respectively). Preoperative chemoradiation (preop CRT) was associated with a higher probability of having a R0 resection. Waiting time after preoperative treatment was inversely related with the chance of developing a LR, especially after R+ resection. In 16% of all cases a LR developed. Five-year disease free survival and overall survival (OS) were 55% and 56% respectively. Conclusions An acceptable survival can be achieved in treatment of patients with initially unresectable T4 rectal cancer with combined modality therapy that includes preop CRT and IOERT. Completeness of the resection is the most important predictive and

    OBJECTIVE To compare the estimated prevalence of, risk factors for, and level of bother associated with subjectively reported and objectively measured pelvic organ prolapse in a racially diverse cohort. METHODS The Reproductive Risks for Incontinence Study at Kaiser 2 is a population-based cohort study of 2,270 middle-aged and older women. Symptomatic prolapse was self-reported, and bother was assessed on a five-point scale. In 1,137 women, prolapse was measured with the Pelvic Organ Prolapse Quantification (POP-Q) system. Multivariable logistic regression analysis was used to identify the independent association of prolapse and race while controlling for risk factors. RESULTS The participants’ mean (standard deviation) age was 55 (9) years, and 44% were white, 20% were African American, 18% were Asian American, and 18% were Latina or other race. Seventy-four women (3%) reported symptomatic prolapse. In multivariable analysis, the risk of symptomatic prolapse was higher in white (prevalence ratio 5.35, 95% confidence interval [CI] 1.89–15.12) and Latina (prevalence ratio 4.89, 95% CI 1.64–14.58) compared with African-American women. Race was not associated with report of moderate to severe bother. Degree of prolapse by POP-Q stage was similar across all racial groups; however, the risk of the leading edge of prolapse at or beyond the hymen was higher in white (prevalence ratio 1.40, 95% CI 1.02–1.92) compared with African-American women. CONCLUSION Compared with African-American women, Latina and white women had four to five times higher risk of symptomatic prolapse, and white women had 1.4-fold higher risk of objective prolapse with leading edge of prolapse at or beyond the hymen.

    Objective The objective of this study was to profile patients who undergo defecography, by age and gender, as well as to describe the main imaging and diagnostic findings in this population. Materials and Methods This was a retrospective, descriptive study of 39 patients, conducted between January 2012 and February 2014. The patients were evaluated in terms of age, gender, and diagnosis. They were stratified by age, and continuous variables are expressed as mean ± standard deviation. All possible quantitative defecography variables were evaluated, including rectal evacuation, perineal descent, and measures of the anal canal. Results The majority (95%) of the patients were female. Patient ages ranged from 18 to 82 years (mean age, 52 ± 13 years): 10 patients were under 40 years of age; 18 were between 40 and 60 years of age; and 11 were over 60 years of age. All 39 of the patients evaluated had abnormal radiological findings. The most prevalent diagnoses were rectocele (in 77%) and enterocele (in 38%). Less prevalent diagnoses were vaginal prolapse, uterine prolapse, and Meckel's diverticulum (in 2%, for all). Conclusion Although defecography is performed more often in women, both genders can benefit from the test. Defecography can be performed in order to detect complex disorders such as uterine and rectal prolapse, as well as to detect basic clinical conditions such as rectocele or enterocele. PMID:28100932

    Background Locally advanced rectal cancers (LARCs) involve one or more of the adjacent organs in upto 10-20% patients. The cause of the adhesions may be inflammatory or neoplastic, and the exact causes cannot be determined pre- or intra-operatively. To achieve complete resection, partial or total mesorectal excision (TME) en bloc with the involved organs is essential. The primary objective of this study is to determine short-term oncological and clinical outcomes in these patients undergoing multivisceral resections (MVRs). Methods This is a retrospective review of a prospectively maintained database. Between 1 July 2013 and 31 May 2015, all patients undergoing MVRs for adenocarcinoma of the rectum were identified from this database. All patients who had en bloc resection of an adjacent organ or part of an adjacent organ were included. Those with unresectable metastatic disease after neoadjuvant therapy were excluded. Results Fifty-four patients were included in the study. Median age of the patients was 43 years. Mucinous histology was detected in 29.6% patients, and signet ring cell adenocarcinoma was found in 24.1% patients. Neoadjuvant therapy was given in 83.4% patients. R0 resection was achieved in 87% patients. Five-year overall survival (OS) was 70% for the entire cohort of population. Conclusions In Indian subcontinent, MVRs in young patients with high proportion of signet ring cell adenocarcinomas based on magnetic resonance imaging (MRI) of response assessment (MRI 2) is associated with similar circumferential resection margin (CRM) involvement and similar adjacent organ involvement as the western patients who are older and surgery is being planned on MRI 1 (baseline pelvis). However, longer follow-up is needed to confirm noninferiority of oncological outcomes. PMID:27284465

    Microbicides, primarily used as topical pre-exposure prophylaxis, have been proposed to prevent sexual transmission of HIV. This review covers the trends and challenges in the development of safe and effective microbicides to prevent sexual transmission of HIV Initial phases of microbicide development used such surfactants as nonoxynol-9 (N-9), C13G, and sodium lauryl sulfate, aiming to inactivate the virus. Clinical trials of microbicides based on N-9 and C31G failed to inhibit sexual transmission of HIV. On the contrary, N-9 enhanced susceptibility to sexual transmission of HIV-1. Subsequently, microbicides based on polyanions and a variety of other compounds that inhibit the binding, fusion, or entry of virus to the host cells were evaluated for their efficacy in different clinical setups. Most of these trials failed to show either safety or efficacy for prevention of HIV transmission. The next phase of microbicide development involved antiretroviral drugs. Microbicide in the form of 1% tenofovir vaginal gel when tested in a Phase IIb trial (CAPRISA 004) in a coitally dependent manner revealed that tenofovir gel users were 39% less likely to become HIV-infected compared to placebo control. However, in another trial (VOICE MTN 003), tenofovir gel used once daily in a coitally independent mode failed to show any efficacy to prevent HIV infection. Tenofovir gel is currently in a Phase III safety and efficacy trial in South Africa (FACTS 001) employing a coitally dependent dosing regimen. Further, long-acting microbicide-delivery systems (vaginal ring) for slow release of such antiretroviral drugs as dapivirine are also undergoing clinical trials. Discovering new markers as correlates of protective efficacy, novel long-acting delivery systems with improved adherence in the use of microbicides, discovering new compounds effective against a broad spectrum of HIV strains, developing multipurpose technologies incorporating additional features of efficacy against other

    Background: Preoperative radiotherapy (RT) is widely used to downstage rectal tumours, but the rate of recurrence varies significantly. Therefore, new biomarkers are needed for better treatment and prognosis. It has been shown that astrocyte elevated gene-1 (AEG-1) is a key mediator of migration, invasion, and treatment resistance. Our aim was to analyse the AEG-1 expression in relation to RT in rectal cancer patients and to test its radiosensitising properties. Methods: The AEG-1 expression was examined by immunohistochemistry in 158 patients from the Swedish clinical trial of RT. Furthermore, we inhibited the AEG-1 expression by siRNA in five colon cancer cell lines and measured the survival after irradiation by colony-forming assay. Results: The AEG-1 expression was increased in the primary tumours compared with the normal mucosa independently of the RT (P<0.01). High AEG-1 expression in the primary tumour of the patients treated with RT correlated independently with higher risk of distant recurrence (P=0.009) and worse disease-free survival (P=0.007). Downregulation of AEG-1 revealed a decreased survival after radiation in radioresistant colon cancer cell lines. Conclusions: The AEG-1 expression was independently related to distant recurrence and disease-free survival in rectal cancer patients with RT and could therefore be a marker to discriminate patients for distant relapse.

    Frequently, vaginal fold prolapse is the protrusion of edematous vaginal tissue into and through the opening of the vulva occurring during proestrus and estrus stages of the sexual cycle. True vaginal prolapse may occur near parturition, as the concentration of serum progesterone declines and the concentration of serum oestrogen increases. In the bitch, this type of true vaginal prolapse is a very rare condition. This short communication describes a 5-year-old female, cross-breed dog in moderate condition, weighing 33 kg, with distocia and true vaginal prolapse. Abdominal palpation and transabdominal ultrasonography revealed live and dead foetuses in the uterine horns. One dead and four live fetuses were removed from uterus by cesarean section. The ovariohysterectomy was performed after repositioning the vaginal wall with a combination of traction from within the abdomen and external manipulation through the vulva. Re-occurrence of a vaginal prolapse was not observed and the bitch recovered completely after the surgical therapy. Compared to other vaginal disorders, vaginal prolapse is an uncommon condition in the bitch. In the present case, extreme tenesmus arising from distocia may have predisposed to the vaginal prolapse. The cause of dystocia was probably the disposition of the first foetus. We concluded that the vaginal prolapse was the result of dystocia in the present case.

    The complications and results of rectal anastomoses carried out with the end-to-end anastomosis (EEA) stapling instrument on 50 patients by 5 consultant surgeons are recorded. There was a clinical leakage rate of 6% and a radiological leakage rate of 20% assessed by water-soluble contrast enema. The technique has advantages compared with hand-suture by allowing low anastomoses and preservation of sphincters and is accompanied by an acceptably low leakage rate. Despite the cost of disposable cartridges these advantages make the technique economical because of the avoidance of colostomies and reduction in hospital stay. Images FIG. 1 FIG. 2 PMID:7044253

    OBJECTIVE: To establish the incidence and types of utero-vaginal prolapse. METHODS: Retrospective medical records analyses of women who were subjected to reconstructive pelvic surgery for various types of pelvic relaxation at the Nnamdi Azikiwe University Teaching Hospital, Nnewi and the University Of Nigeria Teaching Hospital, Enugu, Nigeria was carried out. The study was conducted from January 1996 to December 1999 during which there were 7515 surgical admissions. The inclusion criteria were those women who complained of feeling a mass in the vagina with demonAstrable descent of the anterior and/or posterior and/or apical vaginal walls and/or perineal descent. Excluded were patients who had other symptoms other than utero-vaginal prolapse and those whose grades and sites of prolapse were not determinable from the clinical or surgical notes. Also excluded were patients with nerve injury or disease, connective tissue disorders and neuromuscular diseases. The subjects were divided into two groups. Group I consisted of 54 women (age < or = 40 years), and group II included 105 women (age > or = 40 years). The findings between those two groups were compared with reference to sites, types and degree of prolapse. Also, coexistence of pelvic relaxation and underlying medical conditions were evaluated. RESULTS: A total of 159 subjects out of 492 charts studied met the inclusion criteria for the study. In group I, mean age was 32.839 with a standard deviation (SD) of +/- 6.012 years; and in group II the mean age was 56.543 with a SD of 8.094. Hypertrophic (elongated) cervix was determined in 15 (6.3%) subjects in group I for an incidence of 1.58% per year, cystocele (vaginal anterior wall descent) was present in 21 (8.9%) women for an incidence of 2.2% per year; rectocele (posterior vaginal wall descent) was identified in 15 (6.3%) women for an incidence of 1.58% per year; vaginal cough prolapse (apical descent) was present 21 (8.9%) women for an incidence of 2.2% per year

    Background: Genital prolapse is an important cause of morbidity among postmenopausal and multiparous women especially in our environment where a high premium is placed on large family size. This study was done to determine the prevalence, risk factors, clinical presentation, and management options of genital prolapse. Patients and Methods: Data of those diagnosed with genital prolapse were retrieved from records in the clinic, wards, theater, and from patients' folders in the medical records department. Statistical Analysis Used: Data were analyzed using Statistical Package for Social Sciences version 20 with P < 0.05. Results: Genital prolapse accounted for 0.8% of gynecological clinic attendances and 5.2% of major gynecological operations. The mean age of patients was 56.7 ± 15.5 years. Farmers constituted 60.7% of the patients while 72.1% and 70.5% were postmenopausal and grandmultiparous women, respectively. The sensation of something coming down the vagina was the most common symptom noted in 98.4% of the patients. Most (23.0%) of the patients had unsupervised delivery at home. Uterovaginal prolapse was the most common (70.5%) type of genital prolapse, and third-degree uterovaginal prolapse was its most frequent presentation. Majority of the patients (44.4%) were managed expectantly while the most common surgery performed was vaginal hysterectomy with pelvic floor repair (33.3%). Conclusion: Widespread availability of antenatal services especially in the rural communities and limitation on family size can significantly reduce the burden of this disease. PMID:27833248

    Purpose: To correlate changes in 2-deoxy-2-[18F]fluoro-D-glucose (18-FDG) positron emission tomography (PET) (18-FDG-PET) uptake with response and disease-free survival with combined modality neoadjuvant therapy in patients with locally advanced rectal cancer. Methods and Materials: Charts were reviewed for consecutive patients with ultrasound-staged T3x to T4Nx or TxN1 rectal adenocarcinoma who underwent preoperative chemoradiation therapy at Fox Chase Cancer Center (FCCC) or Robert H. Lurie Comprehensive Cancer Center of Northwestern University with 18-FDG-PET scanning before and after combined-modality neoadjuvant chemoradiation therapy . The maximum standardized uptake value (SUV) was measured from the tumor before and 3 to 4 weeks after completion of chemoradiation therapy preoperatively. Logistic regression was used to analyze the association of pretreatment SUV, posttreatment SUV, and % SUV decrease on pathologic complete response (pCR), and a Cox model was fitted to analyze disease-free survival. Results: A total of 53 patients (FCCC, n = 41, RLCCC, n = 12) underwent pre- and postchemoradiation PET scanning between September 2000 and June 2006. The pCR rate was 31%. Univariate analysis revealed that % SUV decrease showed a marginally trend in predicting pCR (p = 0.08). In the multivariable analysis, posttreatment SUV was shown a predictor of pCR (p = 0.07), but the test results did not reach statistical significance. None of the investigated variables were predictive of disease-free survival. Conclusions: A trend was observed for % SUV decrease and posttreatment SUV predicting pCR in patients with rectal cancer treated with preoperative chemoradiation therapy. Further prospective study with a larger sample size is warranted to better characterize the role of 18-FDG-PET for response prediction in patients with rectal cancer.

    Purpose: To assess the long-term outcomes of patients with rectal cancer who received neoadjuvant chemoradiation therapy (NCRT) with concurrent S-1 and irinotecan (S-1/irinotecan) therapy. Methods and Materials: The study group consisted of 115 patients with clinical stage T3 or T4 rectal cancer. Patients received pelvic radiation therapy (45 Gy) plus concurrent oral S-1/irinotecan. The median follow-up was 60 months. Results: Grade 3 adverse effects occurred in 7 patients (6%), and the completion rate of NCRT was 87%. All 115 patients (100%) were able to undergo R0 surgical resection. Twenty-eight patients (24%) had a pathological complete response (ypCR). At 60 months, the local recurrence-free survival was 93%, disease-free survival (DFS) was 79%, and overall survival (OS) was 80%. On multivariate analysis with a proportional hazards model, ypN2 was the only independent prognostic factor for DFS (P=.0019) and OS (P=.0064) in the study group as a whole. Multivariate analysis was additionally performed for the subgroup of 106 patients with ypN0/1 disease, who had a DFS rate of 85.3%. Both ypT (P=.0065) and tumor location (P=.003) were independent predictors of DFS. A combination of these factors was very strongly related to high risk of recurrence (P<.0001), which occurred most commonly in the lung. Conclusions: NCRT with concurrent S-1/irinotecan produced high response rates and excellent long-term survival, with acceptable adverse effects in patients with rectal cancer. ypN2 is a strong predictor of dismal outcomes, and a combination of ypT and tumor location can identify high-risk patients among those with ypN0/1 disease.

    Background Tafazzin (TAZ), a transmembrane protein contributes in mitochondrial structural and functional modifications through cardiolipin remodeling. TAZ mutations are associated with several diseases, but studies on the role of TAZ protein in carcinogenesis and radiotherapy (RT) response is lacking. Therefore we investigated the TAZ expression in rectal cancer, and its correlation with RT, clinicopathological and biological variables in the patients participating in a clinical trial of preoperative RT. Methods 140 rectal cancer patients were included in this study, of which 65 received RT before surgery and the rest underwent surgery alone. TAZ expression was determined by immunohistochemistry in primary cancer, distant, adjacent normal mucosa and lymph node metastasis. In-silico protein-protein interaction analysis was performed to study the predictive functional interaction of TAZ with other oncoproteins. Results TAZ showed stronger expression in primary cancer and lymph node metastasis compared to distant or adjacent normal mucosa in both non-RT and RT patients. Strong TAZ expression was significantly higher in stages I-III and non-mucinious cancer of non-RT patients. In RT patients, strong TAZ expression in biopsy was related to distant recurrence, independent of gender, age, stages and grade (p = 0.043, HR, 6.160, 95% CI, 1.063–35.704). In silico protein-protein interaction study demonstrated that TAZ was positively related to oncoproteins, Livin, MAC30 and FXYD-3. Conclusions Strong expression of TAZ protein seems to be related to rectal cancer development and RT response, it can be a predictive biomarker of distant recurrence in patients with preoperative RT.

  14. Role of urodynamics before prolapse surgery.

    PubMed

    Serati, Maurizio; Giarenis, Ilias; Meschia, Michele; Cardozo, Linda

    2015-02-01

    The role of urodynamic studies (UDS) before prolapse surgery is contentious and a hotly debated topic in urogynaecology. Previous studies in women with prolapse and women with uncomplicated stress urinary incontinence (SUI) have focused on women without preoperative incontinence. Currently, it has not been possible to reach a universal consensus on the role of UDS before prolapse surgery in women with concomitant symptomatic or occult SUI. It is clear that UDS could add some information in women undergoing pelvic organ prolapse surgery and could facilitate counselling of patients. However, there is no evidence that the outcome of surgery is altered by prior UDS. New well-designed randomized studies are necessary to improve our understanding of this topic.

    Secondary perineal herniation of intraperitoneal contents represents a rare complication following procedures such as abdominoperineal rectal resection or cystectomy. We present a case of a perineal hernia formation with prolapse of an ileum neobladder following radical cystectomy and rectal resection for recurrent bladder cancer. Following consecutive resections in the anterior and posterior compartment of the lesser pelvis, the patient developed problems emptying his neobladder. Clinical examination and computed tomography revealed perineal herniation of his neobladder through the pelvic floor. Through a perineal approach, the hernial sac could be repositioned, and via a combination of absorbable and non-absorbable synthetic mesh grafts, the pelvic floor was stabilised. Follow-up review at one year after hernia fixation showed no signs of recurrence and no symptoms. In cases of extensive surgery in the lesser pelvis with associated weakness of the pelvic compartments, meshes should be considered for closure of the pelvic floor. Development of biological meshes with reduced risk of infection might be an interesting treatment option in these cases. PMID:26985818

    Purpose: Cetuximab-containing chemotherapy is known to be effective for KRAS wild-type metastatic colorectal cancer; however, it is not clear whether cetuximab-based preoperative chemoradiation confers an additional benefit compared with chemoradiation without cetuximab in patients with locally advanced rectal cancer. Methods and Materials: We analyzed EGFR, KRAS, BRAF, and PIK3CA mutation status with direct sequencing and epidermal growth factor receptor (EGFR) and Phosphatase and tensin homolog (PTEN) expression status with immunohistochemistry in tumor samples of 82 patients with locally advanced rectal cancer who were enrolled in the IRIX trial (preoperative chemoradiation with irinotecan and capecitabine; n=44) or the ERBIRIX trial (preoperative chemoradiation with irinotecan and capecitabine plus cetuximab; n=38). Both trials were similarly designed except for the administration of cetuximab; radiation therapy was administered at a dose of 50.4 Gy/28 fractions and irinotecan and capecitabine were given at doses of 40 mg/m{sup 2} weekly and 1650 mg/m{sup 2}/day, respectively, for 5 days per week. In the ERBIRIX trial, cetuximab was additionally given with a loading dose of 400 mg/m{sup 2} on 1 week before radiation, and 250 mg/m{sup 2} weekly thereafter. Results: Baseline characteristics before chemoradiation were similar between the 2 trial cohorts. A KRAS mutation in codon 12, 13, and 61 was noted in 15 (34%) patients in the IRIX cohort and 5 (13%) in the ERBIRIX cohort (P=.028). Among 62 KRAS wild-type cancer patients, major pathologic response rate, disease-free survival and pathologic stage did not differ significantly between the 2 cohorts. No mutations were detected in BRAF exon 11 and 15, PIK3CA exon 9 and 20, or EGFR exon 18-24 in any of the 82 patients, and PTEN and EGFR expression were not predictive of clinical outcome. Conclusions: In patients with KRAS wild-type locally advanced rectal cancer, the addition of cetuximab to the chemoradiation with

  18. Intensity modulated radiation therapy (IMRT): differences in target volumes and improvement in clinically relevant doses to small bowel in rectal carcinoma

    PubMed Central

    2011-01-01

    Background A strong dose-volume relationship exists between the amount of small bowel receiving low- to intermediate-doses of radiation and the rates of acute, severe gastrointestinal toxicity, principally diarrhea. There is considerable interest in the application of highly conformal treatment approaches, such as intensity-modulated radiation therapy (IMRT), to reduce dose to adjacent organs-at-risk in the treatment of carcinoma of the rectum. Therefore, we performed a comprehensive dosimetric evaluation of IMRT compared to 3-dimensional conformal radiation therapy (3DCRT) in standard, preoperative treatment for rectal cancer. Methods Using RTOG consensus anorectal contouring guidelines, treatment volumes were generated for ten patients treated preoperatively at our institution for rectal carcinoma, with IMRT plans compared to plans derived from classic anatomic landmarks, as well as 3DCRT plans treating the RTOG consensus volume. The patients were all T3, were node-negative (N = 1) or node-positive (N = 9), and were planned to a total dose of 45-Gy. Pairwise comparisons were made between IMRT and 3DCRT plans with respect to dose-volume histogram parameters. Results IMRT plans had superior PTV coverage, dose homogeneity, and conformality in treatment of the gross disease and at-risk nodal volume, in comparison to 3DCRT. Additionally, in comparison to the 3DCRT plans, IMRT achieved a concomitant reduction in doses to the bowel (small bowel mean dose: 18.6-Gy IMRT versus 25.2-Gy 3DCRT; p = 0.005), bladder (V40Gy: 56.8% IMRT versus 75.4% 3DCRT; p = 0.005), pelvic bones (V40Gy: 47.0% IMRT versus 56.9% 3DCRT; p = 0.005), and femoral heads (V40Gy: 3.4% IMRT versus 9.1% 3DCRT; p = 0.005), with an improvement in absolute volumes of small bowel receiving dose levels known to induce clinically-relevant acute toxicity (small bowel V15Gy: 138-cc IMRT versus 157-cc 3DCRT; p = 0.005). We found that the IMRT treatment volumes were typically larger than that covered by classic

    Vesicostomy prolapse is a frequent complication of an unusual surgical technique in adult patients. We have described a surgical technique to repair a vesicostomy prolapse using subcutaneous tubulisation of thick cutaneous flap taken off the abdominal wall. This technique could help surgeons to cure prolapse of vesicostomy in case of impossible intraperitoneal approach.

    2015-01-01

    Background: National Surgical Adjuvant Breast and Bowel Project R-04 was designed to determine whether the oral fluoropyrimidine capecitabine could be substituted for continuous infusion 5-FU in the curative setting of stage II/III rectal cancer during neoadjuvant radiation therapy and whether the addition of oxaliplatin could further enhance the activity of fluoropyrimidine-sensitized radiation. Methods: Patients with clinical stage II or III rectal cancer undergoing preoperative radiation were randomly assigned to one of four chemotherapy regimens in a 2x2 design: CVI 5-FU or oral capecitabine with or without oxaliplatin. The primary endpoint was local-regional tumor control. Time-to-event endpoint distributions were estimated using the Kaplan-Meier method. Hazard ratios were estimated from Cox proportional hazard models. All statistical tests were two-sided. Results: Among 1608 randomized patients there were no statistically significant differences between regimens using 5-FU vs capecitabine in three-year local-regional tumor event rates (11.2% vs 11.8%), 5-year DFS (66.4% vs 67.7%), or 5-year OS (79.9% vs 80.8%); or for oxaliplatin vs no oxaliplatin for the three endpoints of local-regional events, DFS, and OS (11.2% vs 12.1%, 69.2% vs 64.2%, and 81.3% vs 79.0%). The addition of oxaliplatin was associated with statistically significantly more overall and grade 3–4 diarrhea (P < .0001). Three-year rates of local-regional recurrence among patients who underwent R0 resection ranged from 3.1 to 5.1% depending on the study arm. Conclusions: Continuous infusion 5-FU produced outcomes for local-regional control, DFS, and OS similar to those obtained with oral capecitabine combined with radiation. This study establishes capecitabine as a standard of care in the pre-operative rectal setting. Oxaliplatin did not improve the local-regional failure rate, DFS, or OS for any patient risk group but did add considerable toxicity. PMID:26374429

  2. Concomitant boost IMRT-based neoadjuvant chemoradiotherapy for clinical stage II/III rectal adenocarcinoma: results of a phase II study

    2014-01-01

    Aim This study was designed to evaluate the efficacy and toxicities of concomitant boost intensity-modulated radiation therapy (IMRT) along with capecitabine and oxaliplatin, followed by a cycle of Xelox, in neoadjuvant course for locally advanced rectal cancer. Materials and methods Patients with histologically confirmed, newly diagnosed, locally advanced rectal adenocarcinoma (cT3-T4 and/or cN+) located within 12 cm of the anal verge were included in this study. Patients received IMRT to the pelvis of 50 Gy and a concomitant boost of 5 Gy to the primary tumor in 25 fractions, and concurrent with oxaliplatin (50 mg/m2 d1 weekly) and capecitabine (625 mg/m2 bid d1–5 weekly). One cycle of Xelox (oxaliplatin 130 mg/m2 on d1 and capecitabine 1000 mg/m2 twice daily d1–14) was given two weeks after the completion of chemoradiation, and radical surgery was scheduled eight weeks after chemoradiation. Tumor response was evaluated by tumor regression grade (TRG) system and acute toxicities were evaluated by NCI-CTC 3.0 criteria. Survival curves were estimated using the Kaplan-Meier method and compared with Log-rank test. Results A total of 78 patients were included between March 2009 and May 2011 (median age 54 years; 62 male). Seventy-six patients underwent surgical resection. Twenty-eight patients underwent sphincter-sparing lower anterior resection and 18 patients (23.7%) were evaluated as pathological complete response (pCR). The incidences of grade 3 hematologic toxicity, diarrhea, and radiation dermatitis were 3.8%, 10.3%, and 17.9%, respectively. The three-year LR (local recurrence), DFS (disease-free survival) and OS (overall survival) rates were 14.6%, 63.8% and 77.4%, respectively. Initial clinical T stage and tumor regression were independent prognostic factors to DFS. Conclusion An intensified regimen of concomitant boost radiotherapy plus concurrent capecitabine and oxaliplatin, followed by one cycle of Xelox, can be safely administered in patients

    Background Robotic mitral valve (MV) repair is the least invasive surgical approach to the MV and provides unparalleled access to the valve. We sought to assess technical aspects and clinical outcomes of robotic MV repair for isolated posterior leaflet prolapse by examining the first 623 such cases performed in a tertiary care center. Methods We reviewed the first 623 patients (mean age 56±9.7 years) with isolated posterior leaflet prolapse who underwent robotic primary MV repair from 01/2006 to 11/2013. All procedures were performed via right chest access with femoral perfusion for cardiopulmonary bypass. Results MV repair was attempted in all patients; 622 (99.8%) underwent MV repair and only 1 (0.2%) converted to replacement. After an initial attempt at robotic MV repair, 8 (1.3%) patients were converted to sternotomy as a result of management of residual mitral regurgitation (n=3), bleeding (n=1), difficulties with surgical exposure (n=2), aortic valve injury (n=1), and aortic dissection (n=1). Intraoperative post-repair echocardiography confirmed that all patients left the operating room with MR graded as mild or less, and pre-discharge echocardiography confirmed mild or less MR in 573 (99.1%). There was no hospital death, sternal wound infection, or renal failure. Seven (1.1%) patients suffered a stroke, 11 (1.8%) patients underwent re-exploration for bleeding, and 111 (19%) experienced new-onset atrial fibrillation. The mean intensive care unit length of stay and hospital length of stay were 29±17 hours and 4.6±1.6 days, respectively. Conclusions At a large tertiary care referral center, robotic MV repair for posterior prolapse is associated with zero mortality, infrequent operative morbidity, and near 100% successful repair. The combination of a patient selection algorithm and increased experience improved clinical outcomes and procedural efficiency. PMID:28203538

    Purpose: To review the risk of local recurrence and impact of salvage therapy after Watch and Wait for rectal cancer with complete clinical response (cCR) after chemoradiation therapy (CRT). Methods and Materials: Patients with cT2-4N0-2M0 distal rectal cancer treated with CRT (50.4-54 Gy + 5-fluorouracil-based chemotherapy) and cCR at 8 weeks were included. Patients with cCR were enrolled in a strict follow-up program with no immediate surgery (Watch and Wait). Local recurrence-free survival was compared while taking into account Watch and Wait strategy alone and Watch and Wait plus salvage. Results: 90 of 183 patients experienced cCR at initial assessment after CRT (49%). When early tumor regrowths (up to and including the initial 12 months of follow-up) and late recurrences were considered together, 28 patients (31%) experienced local recurrence (median follow-up time, 60 months). Of those, 26 patients underwent salvage therapy, and 2 patients were not amenable to salvage. In 4 patients, local re-recurrence developed after Watch and Wait plus salvage. The overall salvage rate for local recurrence was 93%. Local recurrence-free survival at 5 years was 69% (all local recurrences) and 94% (after salvage procedures). Thirteen patients (14%) experienced systemic recurrence. The 5-year cancer-specific overall survival and disease-free survival for all patients (including all recurrences) were 91% and 68%, respectively. Conclusions: Local recurrence may develop in 31% of patients with initial cCR when early regrowths (≤12 months) and late recurrences are grouped together. More than half of these recurrences develop within 12 months of follow-up. Salvage therapy is possible in ≥90% of recurrences, leading to 94% local disease control, with 78% organ preservation.

    Purpose: To investigate, in rectal cancer, the benefit of a neoadjuvant radiation dose escalation with endocavitary contact radiotherapy (CXRT) in addition to external beam radiotherapy (EBRT). This article provides an update of the Lyon R96-02 Phase III trial. Methods and Materials: A total of 88 patients with T2 to T3 carcinoma of the lower rectum were randomly assigned to neoadjuvant EBRT 39 Gy in 13 fractions (43 patients) vs. the same EBRT with CXRT boost, 85 Gy in three fractions (45 patients). Median follow-up was 132 months. Results: The 10-year cumulated rate of permanent colostomy (CRPC) was 63% in the EBRT group vs. 29% in the EBRT+CXRT group (p < 0.001). The 10-year rate of local recurrence was 15% vs. 10% (p = 0.69); 10-year disease-free survival was 54% vs. 53% (p = 0.99); and 10-year overall survival was 56% vs. 55% (p = 0.85). Data of clinical response (CR) were available for 78 patients (36 in the EBRT group and 42 in the EBRT+CXRT group): 12 patients were in complete CR (1 patient vs. 11 patients), 53 patients had a CR {>=}50% (24 patients vs. 29 patients), and 13 patients had a CR <50% (11 patients vs. 2 patients) (p < 0.001). Of the 65 patients with CR {>=}50%, 9 had an organ preservation procedure (meaning no rectal resection) taking advantage of major CR. The 10-year CRPC was 17% for patients with complete CR, 42% for patients with CR {>=}50%, and 77% for patients with CR <50% (p = 0.014). Conclusion: In cancer of the lower rectum, CXRT increases the complete CR, turning in a significantly higher rate of long-term permanent sphincter and organ preservation.

    Objective Genetic studies require a clearly defined phenotype to reach valid conclusions. Our aim was to characterize the phenotype of advanced prolapse by comparing women with stage III to IV prolapse with controls without prolapse. Methods Based on the pelvic organ prolapse quantification examination, women with stage 0 to stage I prolapse (controls) and those with stage III to stage IV prolapse (cases) were prospectively recruited as part of a genetic epidemiologic study. Data regarding sociodemographics; medical, obstetric, and surgical history; family history; and body mass index were obtained by a questionnaire administered by a trained coordinator and abstracted from electronic medical records. Results There were 275 case patients with advanced prolapse and 206 controls with stage 0 to stage I prolapse. Based on our recruitment strategy, the women were younger than the controls (64.7±10.1 vs 68.6±10.4 years; P<0.001); cases were also more likely to have had one or more vaginal deliveries (96.0% vs 82.0%; P<0.001). There were no differences in race, body mass index, and constipation. Regarding family history, cases were more likely to report that either their mother and/or sister(s) had prolapse (44.8% vs 16.9%, P<0.001). In a logistic regression model, vaginal parity (odds ratio, 4.05; 95% confidence interval, 1.67–9.85) and family history of prolapse (odds ratio, 3.74; 95% confidence interval, 2.16–6.46) remained significantly associated with advanced prolapse. Conclusions Vaginal parity and a family history of prolapse are more common in women with advanced prolapse compared to those without prolapse. These characteristics are important in phenotyping advanced prolapse, suggesting that these data should be collected in future genetic epidemiologic studies. PMID:22983275

    Background: Urinary incontinence is the inability of a woman to maintain bladder control. Symptoms range from urgency, frequency, nocturia to urge incontinence (1). It limits functional and social activities and leads to depression and social withdrawal. (2). This observational study aimed to describe the common urinary problems amongst gynecological consultations. It also describes the relationship of urinary incontinence with history of diabetes, previous gynecological surgery and prolapse. Methods: The study was conducted as a descriptive cross sectional study from Jan-May 2015 at Qassim University Clinic, Buraidah. Women with urinary problem and those without urinary problems were compared for risk factors including diabetes, prolapse and previous gynecological surgery. The Statistical Package for the Social Sciences 22 (SPSS 22) was used to conduct proportion z-tests to determine the association of prolapse, gynecological surgeries and diabetes with urinary incontinence. To test the hypothesis, differences between two groups on the aforementioned factors were examined. The groups included participants that reported having urinary problems (n = 111) and those who do not have urinary problems (n = 100). Results: The most frequent complaints of participants with urinary problems were urgency (n = 66, 59.46%), Stress incontinence (SI) (n = 65, 58.56%) and frequency (n = 62, 55.86%). For participants with a urinary problem, 89.19% have not had a gynecological surgery (n = 99) and the remaining 10.81% of participants had a gynecological surgery (n = 12). For participants without a urinary problem, 97.0% have not had a gynecological surgery (n = 97) and the remaining 3.0% had a gynecological surgery (n = 3). For participants with a urinary problem, 72.97% did not have diabetes (n = 81) and the remaining 27.03% of participants did have diabetes (n = 30). For participants without a urinary problem, 92.0% did not have diabetes (n = 92) and the remaining 8.0% did report

    Laparoscopic rectal surgery has demonstrated its superiority over the open approach, however it still has some technical limitations that lead to the development of robotic platforms. Nevertheless the literature on this topic is rapidly expanding there is still no consensus about benefits of robotic rectal cancer surgery over the laparoscopic one. For this reason a review of all the literature examining robotic surgery for rectal cancer was performed. Two reviewers independently conducted a search of electronic databases (PubMed and EMBASE) using the key words "rectum", "rectal", "cancer", "laparoscopy", "robot". After the initial screen of 266 articles, 43 papers were selected for review. A total of 3013 patients were included in the review. The most commonly performed intervention was low anterior resection (1450 patients, 48.1%), followed by anterior resections (997 patients, 33%), ultra-low anterior resections (393 patients, 13%) and abdominoperineal resections (173 patients, 5.7%). Robotic rectal surgery seems to offer potential advantages especially in low anterior resections with lower conversions rates and better preservation of the autonomic function. Quality of mesorectum and status of and circumferential resection margins are similar to those obtained with conventional laparoscopy even if robotic rectal surgery is undoubtedly associated with longer operative times. This review demonstrated that robotic rectal surgery is both safe and feasible but there is no evidence of its superiority over laparoscopy in terms of postoperative, clinical outcomes and incidence of complications. In conclusion robotic rectal surgery seems to overcome some of technical limitations of conventional laparoscopic surgery especially for tumors requiring low and ultra-low anterior resections but this technical improvement seems not to provide, until now, any significant clinical advantages to the patients.

    Introduction and hypothesis To better understand women’s experience with pelvic organ prolapse (POP) symptoms and to describe factors that prevent disease understanding among Spanish- and English speaking women. Methods Women with POP were recruited from female urology and urogynecology clinics in Los Angeles, California and Albuquerque, New Mexico. Eight focus groups were conducted, four in Spanish and four in English. Topics addressed patients’ emotional responses when noticing their prolapse, how they sought support, what verbal and written information was given, and their overall feelings of the process. Additionally, patients were asked about their experience with their treating physician. All interview transcripts were analyzed using Grounded Theory qualitative methods. Results Qualitative analysis yielded two preliminary themes: First, women had misconceptions about what POP was as well as its causes and treatments. Secondly, there was a great deal of miscommunication between patient and physician which led to decreased understanding about the diagnosis and treatment options. This included the fact that women were often overwhelmed with information which they did not understand. The concept emerged that there is a strong need for better methods to achieve disease and treatment understanding for women with POP. Conclusions Our data emphasize that women with POP have considerable misconceptions about their disease. In addition, there is miscommunication during the patient-physician interaction that leads to further confusion among Spanish and English speaking women. Spending more time explaining the diagnosis of POP, rather than focusing solely on treatment options, may reduce miscommunication and increase patient understanding. PMID:25516231

    Purpose: To assess the predictors of late rectal toxicity in a prospectively investigated group of patients treated at 70-80 Gy for prostate cancer (1.8-2 Gy fractions) with three-dimensional conformal radiotherapy. Methods and Materials: A total of 1,132 patients were entered into the study between 2002 and 2004. Three types of rectal toxicity, evaluated by a self-administered questionnaire, mainly based on the subjective objective management, analytic late effects of normal tissue system, were considered: stool frequency/tenesmus/pain, fecal incontinence, and bleeding. The data from 506 patients with a follow-up of 24 months were analyzed. The correlation between a number of clinical and dosimetric parameters and Grade 2 or greater toxicity was investigated by univariate and multivariate (MVA) logistic analyses. Results: Of the 1,132 patients, 21, 15, and 30 developed stool frequency/tenesmus/pain, fecal incontinence, and bleeding, respectively. Stool frequency/tenesmus/pain correlated with previous abdominal/pelvic surgery (MVA, p = 0.05, odds ratio [OR], 3.3). With regard to incontinence, MVA showed the volume receiving {>=}40 Gy (V{sub 40}) (p = 0.035, OR, 1.037) and surgery (p = 0.02, OR, 4.4) to be the strongest predictors. V{sub 40} to V{sub 70} were highly predictive of bleeding; V{sub 70} showed the strongest impact on MVA (p = 0.03), together with surgery (p = 0.06, OR, 2.5), which was also the main predictor of Grade 3 bleeding (p = 0.02, OR, 4.2). Conclusions: The predictive value of the dose-volume histogram was confirmed for bleeding, consistent with previously suggested constraints (V{sub 50} <55%, V{sub 60} <40%, V{sub 70} <25%, and V{sub 75} <5%). A dose-volume histogram constraint for incontinence can be suggested (V{sub 40} <65-70%). Previous abdominal/pelvic surgery correlated with all toxicity types; thus, a modified constraint for bleeding (V{sub 70} <15%) can be suggested for patients with a history of abdominal/pelvis surgery, although

    Introduction A paucity of data exists addressing the quality of care provided to women with pelvic organ prolapse (POP). We sought to develop a means to measure this quality through the development of quality-of-care indicators (QIs). Methods QIs were modeled after those previously described in the Assessing the Care of Vulnerable Elders (ACOVE) project. The indicators were then presented to a panel of nine experts. Using the RAND Appropriateness Method, we analyzed each indicator’s preliminary rankings. A forum was then held in which each indicator was thoroughly discussed by the panelists as a group, after which panelists individually re-rated the indicators. QIs with median scores of at least seven were considered valid. Results QIs were developed that addressed screening, diagnosis, work-up, and both nonsurgical and surgical management. Areas of controversy included whether screening should be performed to identify prolapse, whether pessary users should undergo a vaginal exam by a health professional every six months versus annually, and whether a colpocleisis should be offered to older women planning to undergo surgery for POP. Fourteen of 21 potential indicators were rated as valid for pelvic organ prolapse (median score ≥ 7). Conclusion We developed and rated fourteen potential quality indicators for the care of women with POP. Once these QIs are tested for feasibility they can be used on a larger scale to measure and compare the care provided to women with prolapse in different clinical settings. PMID:23644812

    The apical prolapse has always been considered the most complex of the defects of the pelvic floor, for both the difficulty of the surgical corrective technique and for the high post-surgical recurrence rate. Today, the laparoscopic sacrocolpopexy can be considered the standard treatment for apical prolapse. In the last years, several author performed robotic sacrocolpopexy, obtaining positive results. So, we developed a case-control study in order to compare the surgical outcome of robotic group with a control group of laparoscopic approach in patients with symptomatic apical pro-lapsed between January 2015 and December 2015 at University Hospital Policlinico “P. Giaccone” and Ospedali Riuniti “Villa Sofia-Cervello”, Palermo. Our experience shows that robotic sacrocolpopexy can be considered in positive way for clinical results obtained: all procedures were executed with no complications, we noted a lower intraoperative blood loss and a shorter hospital stay than in laparoscopic group. Although the mean operative time and the economic costs are higher in robotic surgery, this study demonstrates that the use of robotic platform for repairing of symptomatic apical vaginal prolapse is feasible, safe and associated with short-term satisfactory results, representing therefore a valid alternative to laparoscopic approach.

    Objective To estimate whether prolapse severity is a major contributor to urinary incontinence severity, as measured by validated incontinence questionnaires. Methods We analyzed data from two large female stress urinary incontinence (SUI) surgical cohorts: the Stress Incontinence Surgical Treatment Efficacy Trial (SISTEr) study (N=655) and the subsequent Trial of Mid-Urethral Slings (TOMUS) study (N=597). All participants completed a standardized baseline assessment including validated measures of symptom severity, quality of life, objective measures of urine loss [Urogenital Distress Inventory (UDI), Medical, Epidemiologic, and Social Aspects of Aging questionnaire (MESA), Incontinence Impact Questionnaire (IIQ) and pad test], as well as the Pelvic Organ Prolapse – Quantification (POP-Q) assessment. Groups were compared using the χ2 test (categorical measures) or the one-way analysis of variance (continuous measures). Statistical significance was defined at p-value <0.05. Results The SISTEr and TOMUS samples were similar for many variables including age (52 vs. 53 years, respectively), nulliparity (9 vs. 12%), prior UI surgery (14 vs. 13%), and prior hysterectomy (31 vs 28%), but other differences necessitated separate analysis of the two cohorts. There was not a statistically significant difference in UDI scores according to prolapse stage in either study population. Patients with prior surgery for POP and SUI had more incontinence symptoms and were more bothered by their UI, regardless of prolapse stage. Conclusions Prolapse stage is not strongly or consistently associated with incontinence severity in women who select surgical treatment of stress urinary incontinence. Prior POP and UI surgery is associated with worse UI severity and bother. Clinical Trial Registration: ClinicalTrials.gov, www.clinicaltrials.gov, NCT00064662 and NCT00325039. PMID:20093904

    2016-01-01

    Stapled transanal rectal resection (STARR) and stapled hemorrhoidopexy (SH) are well-established techniques for treating rectal prolapse and obstructed defecation syndrome (ODS). Occasionally, they can be associated with severe complications. We describe the case of a 59-year-old woman who underwent STARR for ODS and developed a postoperative pelvic hemorrhage. A computed tomography (CT) scan revealed a vast pelvic, retroperitoneal hematoma and free gas in the abdomen. Laparoscopy ruled out any bowel lesions, but identified a hematoma of the pelvis. Flexible sigmoidoscopy showed a small leakage of the rectal suture. The patient was treated conservatively and recovered completely. Surgeons performing STARR and SH must be aware of the risk of this rare, but severe, complication. If the patient is not progressing after a STARR or SH, a CT scan can be indicated to rule out intra-abdominal and pelvic hemorrhage. Laparoscopy is a diagnostic tool and should be associated with intraluminal exploration with flexible sigmoidoscopy. PMID:27847791

    Sixteen cases of cloacal prolapse in raptors were reviewed in this study. Colonic prolapse was the most common presentation (56% of cases). Red-tailed hawks ( Buteo jamaicensis ) were overrepresented, comprising 66% of colonic prolapse cases. In cases of colonic prolapse, postsurgical stricture formation was a commonly identified complication after resection and anastomosis of the colon. A novel technique was used in 2 cases of colonic prolapse, in which sterile, semirigid rubber tubing was placed in the distal colon and removed per-cloaca at the end of the procedure; this facilitated a secure, fluid-tight anastomosis while maintaining sufficient intestinal lumen. Oviductal prolapse (31% of cases) was associated with the most guarded prognosis (40% treatment success). Cloacoliths were treated successfully in 2 birds (13% of cases) by minimally invasive per-cloacal manual removal.

    Laparoscopic rectal surgery has demonstrated its superiority over the open approach, however it still has some technical limitations that lead to the development of robotic platforms. Nevertheless the literature on this topic is rapidly expanding there is still no consensus about benefits of robotic rectal cancer surgery over the laparoscopic one. For this reason a review of all the literature examining robotic surgery for rectal cancer was performed. Two reviewers independently conducted a search of electronic databases (PubMed and EMBASE) using the key words “rectum”, “rectal”, “cancer”, “laparoscopy”, “robot”. After the initial screen of 266 articles, 43 papers were selected for review. A total of 3013 patients were included in the review. The most commonly performed intervention was low anterior resection (1450 patients, 48.1%), followed by anterior resections (997 patients, 33%), ultra-low anterior resections (393 patients, 13%) and abdominoperineal resections (173 patients, 5.7%). Robotic rectal surgery seems to offer potential advantages especially in low anterior resections with lower conversions rates and better preservation of the autonomic function. Quality of mesorectum and status of and circumferential resection margins are similar to those obtained with conventional laparoscopy even if robotic rectal surgery is undoubtedly associated with longer operative times. This review demonstrated that robotic rectal surgery is both safe and feasible but there is no evidence of its superiority over laparoscopy in terms of postoperative, clinical outcomes and incidence of complications. In conclusion robotic rectal surgery seems to overcome some of technical limitations of conventional laparoscopic surgery especially for tumors requiring low and ultra-low anterior resections but this technical improvement seems not to provide, until now, any significant clinical advantages to the patients.

    Body image, including how a woman views her genitals, has been shown to impact sexuality. Currently, there are no valid and reliable questionnaires to assess body image specific to women with genital changes from pelvic organ prolapse. The purpose of this study was to assess implementation of a body image questionnaire in women with pelvic organ prolapse. The Vaginal Changes Sexual and Body Esteem Scale showed utility and potential for demonstrating change in body image after prolapse surgery. PMID:19718939

    Eleven infants who were suspected clinically of having cows' milk protein sensitive enteropathy were fed with a protein hydrolysate formula for six to eight weeks, after which they had jejunal and rectal biopsies taken before and 24 hours after challenge with cows' milk protein. When challenged six infants (group 1) developed clinical symptoms and five did not (group 2). In group 1 the lesions developed in both the jejunal mucosa (four infants at 24 hours and one at three days), and the rectal mucosa, and the injury was associated with depletion of alkaline phosphatase activity. Infants in group 2 were normal. It seems that rectal injury that develops as a direct consequence of oral challenge with the protein in reactive infants may be used as one of the measurements to confirm the diagnosis of cows' milk protein sensitive enteropathy. Moreover, ingestion of such food proteins may injure the distal colonic mucosa without affecting the proximal small gut in some infants. PMID:2817945

    Purpose: To evaluate the tumor clinical characteristics and quantitative multi-parametric MR imaging features for prediction of response to chemo-radiation treatment (CRT) in locally advanced rectal cancer (LARC). Methods: Forty-three consecutive patients (59.7±6.9 years, from 09/2013 – 06/2014) receiving neoadjuvant CRT followed by surgery were enrolled. All underwent MRI including anatomical T1/T2, Dynamic Contrast Enhanced (DCE)-MRI and Diffusion-Weighted MRI (DWI) prior to the treatment. A total of 151 quantitative features, including morphology/Gray Level Co-occurrence Matrix (GLCM) texture from T1/T2, enhancement kinetics and the voxelized distribution from DCE-MRI, apparent diffusion coefficient (ADC) from DWI, along with clinical information (carcinoembryonic antigen CEA level, TNM staging etc.), were extracted for each patient. Response groups were separated based on down-staging, good response and pathological complete response (pCR) status. Logistic regression analysis (LRA) was used to select the best predictors to classify different groups and the predictive performance were calculated using receiver operating characteristic (ROC) analysis. Results: Individual imaging category or clinical charateristics might yield certain level of power in assessing the response. However, the combined model outperformed than any category alone in prediction. With selected features as Volume, GLCM AutoCorrelation (T2), MaxEnhancementProbability (DCE-MRI), and MeanADC (DWI), the down-staging prediciton accuracy (area under the ROC curve, AUC) could be 0.95, better than individual tumor metrics with AUC from 0.53–0.85. While for the pCR prediction, the best set included CEA (clinical charateristics), Homogeneity (DCE-MRI) and MeanADC (DWI) with an AUC of 0.89, more favorable compared to conventional tumor metrics with an AUC ranging from 0.511–0.79. Conclusion: Through a systematic analysis of multi-parametric MR imaging features, we are able to build models with

    Rectal imaging has evolved substantially during the past 25 years and now offers surgeons exquisite anatomic detail and physiologic information. Dynamic cystoproctography, helical computed tomography, endoscopic ultrasonography, endorectal magnetic resonance imaging, and immunoscintigraphy have become standards for the diagnosis of rectal disease, staging of neoplasia, and survey of therapeutic results. The indications, limitations, and relative costs of current imaging methods are reviewed, and advances in imaging technology that promise future benefits to colorectal surgeons are introduced.

    2013-02-01

    The treatment of locally advanced rectal cancer is a challenge. Surgery, chemotherapy and radiotherapy comprise the multimodal therapy that is administered in most cases. Therefore, a multidisciplinary approach is required. Because this cancer has a high rate of local recurrence, efforts have been made to improve clinical outcomes while minimizing toxicity and maintaining quality of life. Thus, total mesorectal excision technique was developed as the standard surgery, and chemotherapy and radiotherapy have been established as neoadjuvant treatment. Both approaches reduce locoregional relapse. Two neoadjuvant treatments have emerged as standards of care: short-course radiotherapy and long-course chemoradiotherapy with fluoropyrimidines; however, long-course chemoradiotherapy might be more appropriate for low-lying neoplasias, bulky tumours or tumours with near-circumferential margins. If neoadjuvant treatment is not administered and locally advanced stage is demonstrated in surgical specimens, adjuvant chemoradiotherapy is recommended. The addition of chemotherapy to the treatment regimen confers a significant benefit. Adjuvant chemotherapy is widely accepted despite scarce evidence of its benefit. The optimal time for surgery after neoadjuvant therapy, the treatment of low-risk T3N0 neoplasms, the convenience of avoiding radiotherapy in some cases and tailoring treatment to pathological response have been recurrent subjects of debate that warrant more extensive research. Adding new drugs, changing the treatment sequence and selecting the treatment based on prognostic or predictive factors other than stage remain experimental.

    Mesh exposure is the major complication of vaginal prolapse repair. Incidence rates are variable according to the series. Mesh exposure usually occurs during the year following the intervention. We report here the first case of a patient with a late exposure of an anterior vaginal mesh 4 years after a surgical cystocele repair. The mesh has been easily removed at the operative theatre by vaginal approach.

The bitch was euthanased and necropsied, Histological examination confirmed lymphangiosarcomatous invasion of the submucosal and muscular layers of the retroperitoneal, traumatised, prolapsed part of the vagina, the urethra and the ventral rectal wall. The broad ligament was diffusely invaded with tumour which had proliferated into the caudal abdominal space, and 3 small intra-trabecular foci of tumour were found in the right popliteal lymph node near the hilus. Mitotic figures were generally scarce. There was mild subcutaneous oedema of the ventral trunk extending from the axillae to the inner proximal thighs, which had not been evident clinically, and the lymph nodes (peripheral more so than internal) microscopically showed marked trabecular and perivascular fibrosis especially in hilar regions. Other congenital defects were hepatic capsular and central venous fibrosis with lymphatic duplication and dilatation in all areas of connective tissue, ventrally-incongruous half-circular tracheal rings, and multifocal renal dysplasia affecting the right kidney. There was locally-extensive subacute pyelonephritis of the left kidney.

    There has been a high local recurrence rate in rectal cancer. Besides improvements in surgical techniques, both neoadjuvant short-course radiotherapy and long-course chemoradiation improve oncological results. Approximately 40–60% of rectal cancer patients treated with neoadjuvant chemoradiation achieve some degree of pathologic response. However, there is no effective method of predicting which patients will respond to neoadjuvant treatment. Recent studies have evaluated the potential of genetic biomarkers to predict outcome in locally advanced rectal adenocarcinoma treated with neoadjuvant chemoradiation. The articles produced by the PubMed search were reviewed for those specifically addressing a genetic profile's ability to predict response to neoadjuvant treatment in rectal cancer. Although tissue gene microarray profiling has led to promising data in cancer, to date, none of the identified signatures or molecular markers in locally advanced rectal cancer has been successfully validated as a diagnostic or prognostic tool applicable to routine clinical practice.

    2017-04-01

    Chlamydia trachomatis is the most common bacterial sexually transmitted infection in Europe and has large impacts on patients' physical and emotional health. Unidentified asymptomatic rectal Chlamydia trachomatis could be a partial explanation for the high Chlamydia trachomatis prevalence. In this study, we evaluated rectal Chlamydia trachomatis testing in relation to symptoms and sexual habits in women and men who have sex with men. Rectal Chlamydia trachomatis prevalence was 9.1% in women and 0.9% in men who have sex with men. None of the patients reported any rectal symptoms; 59.0% of the women with a rectal Chlamydia trachomatis infection denied anal intercourse and 18.8% did not have a urogenital infection; 9.4% did neither have a urogenital infection nor reported anal sex. We suggest that rectal sampling should be considered in women visiting sexually transmitted infection clinics regardless of rectal symptoms and irrespective of anal intercourse, since our data suggest that several cases of rectal Chlamydia trachomatis otherwise would be missed, thus enabling further disease transmission.

    In film-based intracavitary brachytherapy for cervical cancer, position of the rectal markers may not accurately represent the anterior rectal wall. This study was aimed at analyzing the variability of rectal dose estimation as a result of interfractional variation of marker placement. A cohort of five patients treated with multiple-fraction tandem and ovoid high-dose-rate (HDR) brachytherapy was studied. The cervical os point and the orientation of the applicators were matched among all fractional plans for each patient. Rectal points obtained from all fractions were then input into each clinical treated plan. New fractional rectal doses were obtained and a new cumulative rectal dose for each patient was calculated. The maximum interfractional variation of distances between rectal dose points and the closest source positions was 1.1 cm. The corresponding maximum variability of fractional rectal dose was 65.5%. The percentage difference in cumulative rectal dose estimation for each patient was 5.4%, 19.6%, 34.6%, 23.4%, and 13.9%, respectively. In conclusion, care should be taken when using rectal markers as reference points for estimating rectal dose in HDR cervical brachytherapy. The best estimate of true rectal dose for each fraction should be determined by the most anterior point among all fractions.

    Purpose of review Polypropylene mesh has been widely used in the surgical repair of pelvic organ prolapse. However, low but persistent rates of complications related to mesh, most commonly mesh exposure and pain, have hampered its use. Complications are higher following transvaginal implantation prompting the Food and Drug Administration to release two public health notifications warning of complications associated with transvaginal mesh use (PHN 2008 and 2011) and to upclassify transvaginal prolapse meshes from Class II to Class III devices. Although there have been numerous studies to determine the incidence and management of mesh complications as well as impact on quality of life, few studies have focused on mechanisms. Recent findings In this review, we summarize the current understanding of how mesh textile properties and mechanical behavior impact vaginal structure and function, as well as the local immune response. We also discuss how mesh properties change in response to loading. Summary We highlight a few areas of current and future research to emphasize collaborative strategies that incorporate basic science research to improve patient outcomes. PMID:27517341

    In rectal cancer management, accurate staging by magnetic resonance imaging, neo-adjuvant treatment with the use of radiotherapy, and total mesorectal excision have resulted in remarkable improvement in the oncological outcomes. However, there is substantial discrepancy in the therapeutic approach and failure to adhere to international guidelines among different Greek-Cypriot hospitals. The present guidelines aim to aid the multidisciplinary management of rectal cancer, considering both the local special characteristics of our healthcare system and the international relevant agreements (ESMO, EURECCA). Following background discussion and online communication sessions for feedback among the members of an executive team, a consensus rectal cancer management was obtained. Statements were subjected to the Delphi methodology voting system on two rounds to achieve further consensus by invited multidisciplinary international experts on colorectal cancer. Statements were considered of high, moderate or low consensus if they were voted by ≥80%, 60-80%, or <60%, respectively; those obtaining a low consensus level after both voting rounds were rejected. One hundred and two statements were developed and voted by 100 experts. The mean rate of abstention per statement was 12.5% (range: 2-45%). In the end of the process, all statements achieved a high consensus. Guidelines and algorithms of diagnosis and treatment were proposed. The importance of centralization, care by a multidisciplinary team, adherence to guidelines, and personalization is emphasized. PMID:27064746

    OBJECTIVE: To determine the prevalence of reproduction-related illnesses in a rural community in Lebanon. METHODS: Data were collected through interviews with women in their homes, physical examinations and history taking by physicians in a clinic in the community, and laboratory tests. A total of 557 ever-married women aged 15-60 years were selected randomly. FINDINGS: Just over half of the sample (268, 50.6%) had five or more children, and (320, 78.9%) of women aged < 45 years were using contraception. The prevalence of reproductive tract infections was very low: six (1.2%) women had sexually transmitted diseases and 47 (9.3%) had endogenous reproductive tract infections. None had chlamydial infection or a positive serological finding of syphilis. None had invasive cervical cancer, and only one had cervical dysplasia. In contrast, genital prolapse and gynaecological morbidity were elevated. Half of the women studied (251, 49.6%) had genital prolapse, and 153 (30.2%) were obese. CONCLUSION: The prevalence of reproductive tract infections in this conservative rural community in east Lebanon was low. Possible explanations include the conservative nature of the community, the high rate of utilization of health care services, and the liberal use of antibiotics without a prescription. More importantly, the study showed an unexpectedly high prevalence of genital prolapse and obesity--a finding that has clear implications for primary health care priorities in such rural communities.

    This audit aimed to determine the usefulness of microscopy to detect presumptive rectal gonorrhoea (GC) infection in asymptomatic men. We retrospectively audited more than 400 male patients attending a London genitourinary medicine clinic from January 2005 to March 2007 who tested rectal culture positive for Neisseria gonorrhoeae and compared this with the microscopy detection rate. In total, 123/423 (29%) of culture positive samples were microscopy positive. Of those that tested microscopy negative (300/423), 64 (21%) were symptomatic and 236 (79%) asymptomatic. In addition, a time and motion study examined 81 rectal slides over a two-week period to identify microscopy reading time required to make a presumptive diagnosis of GC. Three slides were positive, resulting in six hours and 45 minutes to detect one positive sample. Given the low sensitivity for rectal microscopy coupled with the length of time required to obtain a presumptive positive rectal GC result, we believe rectal microscopy is no longer a cost-effective tool screening for asymptomatic men, and this report supports the BASHH guideline that it is not recommended in the management of asymptomatic rectal infection.

    Due to differences in anatomy, primary rectal and colon cancer require different staging procedures, different neo-adjuvant treatment and different surgical approaches. For example, neoadjuvant radiotherapy or chemoradiotherapy is administered solely for rectal cancer. Neoadjuvant therapy and total mesorectal excision for rectal cancer might be responsible in part for the differing effect of adjuvant systemic treatment on overall survival, which is more evident in colon cancer than in rectal cancer. Apart from anatomic divergences, rectal and colon cancer also differ in their embryological origin and metastatic patterns. Moreover, they harbor a different composition of drug targets, such as v-raf murine sarcoma viral oncogene homolog B (BRAF), which is preferentially mutated in proximal colon cancers, and the epidermal growth factor receptor (EGFR), which is prevalently amplified or overexpressed in distal colorectal cancers. Despite their differences in metastatic pattern, composition of drug targets and earlier local treatment, metastatic rectal and colon cancer are, however, commonly regarded as one entity and are treated alike. In this review, we focused on rectal cancer and its biological and clinical differences and similarities relative to colon cancer. These aspects are crucial because they influence the current staging and treatment of these cancers, and might influence the design of future trials with targeted drugs.

    2005-01-01

    Background: Mitral valve prolapse (MVP) is common in women. Other clinical features such as flexibility and hyperlaxity are often associated with MVP, as there is a common biochemical and histological basis for collagen tissue characteristics, range of joint motion, and mitral leaflet excursion. Objective: To confirm whether adult women with MVP are more flexible and hypermobile than those without. Methods: Data from 125 women (mean age 50 years), 31 of them with MVP, were retrospectively analysed with regard to clinical and kinanthropometric aspects. Passive joint motion was evaluated in 20 body movements using Flexitest and three laxity tests. Flexitest individual movements (0 to 4) and overall Flexindex scores were obtained in all subjects by the same investigator. Results: Women with MVP were lighter, less endomorphic and mesomorphic, and more linear. The Flexindex was significantly higher in the women with MVP, both absolute (48 (1.6) v 41 (1.3); p<0.01) and centile for age (67 v 42; p<0.01) values. In 13 out of 20 movements, the Flexitest scores were significantly higher for the women with MVP. Signs of hyperlaxity were about five times more common in these women: 74% v 16% (p<0.01). Scores of 0 and 1 in elbow extension, absence of hyperlaxity, and a Flexindex centile below 65 were almost never found in women with MVP. Conclusion: Flexitest, alone or combined with hyperlaxity tests, may be useful in the assessment of adult women with MVP. PMID:16183767

    Summary Background Myxomatous mitral valve with prolapse are classically seen with abnormal leaflet apposition during contraction of the heart. Hemodynamic disorders can result from eccentric mitral regurgitation usually caused by chordae tendinae rupture or papillary muscle dysfunction. Echocardiography is the gold standard for evaluation of leaflet flail and prolapse due to high sensitivity and specificity. Though most mitral valve prolapse are asymptomatic those that cause severe regurgitation need emergent surgical intervention to prevent disease progression. Case Report We report a 54 year old Hispanic male who presented with progressively worsening dyspnea and palpitations. Initial evaluation was significant for atrial fibrillation on electrocardiogram with subsequent echocardiography revealing myxomatous mitral valve with prolapse. Following surgical repair of the mitral valve, the dyspnea and palpitations resolved. Conclusions Mitral valve prolapse is a common valvular abnormality but the pathogenic cause of myxomatous valves has not been elucidated. Several theories describe multiple superfamilies of proteins to be involved in the process. Proper identification of these severe mitral regurgitation due to these disease valves will help relieve symptomatic mitral valve prolapse patients. PMID:27279924

    The aim of this study was to determine whether there is an association between architectural distortion seen on magnetic resonance (MR) scans (lateral "spill" of the vagina and posterior extension of the space of Retzius) and pelvic organ prolapse. Secondary analysis of MR imaging scans from a case-control study of women with prolapse (maximum point > or = + 1 cm; N = 144) and normal controls (maximum point < or = -1 cm; N= 126) was done. Two independent investigators, blinded to prolapse status and previously established levator-defect scores, determined the presence of architectural distortion on axial MR scans. Women were categorized into three groups based on levator defects and architectural distortion. Among the three groups, women with levator defects and architectural distortion have the highest proportion of prolapse (78%; p < 0.001). Among women with levator defects, those with prolapse had an odds ratio of 2.2 for the presence of architectural distortion (95% CI = 1.1-4.6). Pelvic organ prolapse is associated with the presence of visible architectural distortion on MR scans.

    Objective While gel-formulated Rectal Microbicides (RM) are the first to enter clinical trials, rectal douching in preparation for anal intercourse is a common practise, thus RMs formulated as douches may be a convenient alternative to gels. Nonetheless, little is known about potential users’ thoughts regarding douche-formulated RMs or rectal douching practises, data needed to inform the advancement of douche-based RMs. This qualitative study examined thoughts regarding douches, their use as a RM and current douching practises among men who have sex with men and transgender women. Methods Ten focus groups and 36 in-depth interviews were conducted (N=140) to examine the overall acceptability of RM, of which one component focused on rectal douching. Focus groups and interviews were recorded, transcribed verbatim and coded; text relating to rectal douching was extracted and analysed. Sociodemographic information was collected using a self-administered questionnaire. Results Support for a douche-formulated RM centred on the possibility of combined pre-coital hygiene and HIV protection, and it was believed that a deeply-penetrating liquid douche would confer greater HIV protection than a gel. Drawbacks included rectal dryness; impracticality and portability issues; and, potential side effects. Non-commercial douching apparatus use was common and liquids used included detergents, vinegar, bleach, lemon juice and alcohol. Conclusions A douche-formulated RM while desirable and perceived as more effective than a gel-formulated RM also generated questions regarding practicality and side-effects. Of immediate concern were the non-commercial liquids already being used which likely damage rectal epithelia, potentially increasing HIV infection risk. Pre-coital rectal douching is common and a RM formulated as such is desirable, but education on rectal douching practices is needed now. PMID:23966338

    Background Fever is the most common complaint in pediatric medicine and its treatment is recommended in some situations. Paracetamol is the most common antipyretic drug, which has serious side effects such as toxicity along with its positive effects. Diclofenac is one of the strongest non-steroidal anti-inflammatory (NSAID) drugs, which has received little attention as an antipyretic drug. Objectives This study was designed to compare the antipyretic effectiveness of the rectal form of Paracetamol and Diclofenac. Patients and Methods This double-blind controlled clinical trial was conducted on 80 children aged six months to six years old. One group was treated with rectal Paracetamol suppositories at 15 mg/kg dose and the other group received Diclofenac at 1 mg/kg by rectal administration (n = 40). Rectal temperature was measured before and one hour after the intervention. Temperature changes in the two groups were compared. Results The average rectal temperature in the Paracetamol group was 39.6 ± 1.13°C, and 39.82 ± 1.07°C in the Diclofenac group (P = 0.37). The average rectal temperature, one hour after the intervention, in the Paracetamol and the Diclofenac group was 38.39 ± 0.89°C and 38.95 ± 1.09°C, respectively (P = 0.02). Average temperature changes were 0.65 ± 0.17°C in the Paracetamol group and 1.73 ± 0.69°C in the Diclofenac group (P < 0.001). Conclusions In the first one hour, Diclofenac suppository is able to control the fever more efficient than Paracetamol suppositories. PMID:26889398

    Rectal bleeding is very common in general population with a prevalence of 10–20 %. Primary care physicians have to stratify patients basing on urgency and on the colo-rectal cancer risk and to conduct a decision making for the correct management. We report a case of a 61-years-old woman, complaining rectal bleeding and an anal mass attended to their family doctor who does a visit but without a digital rectal examination and diagnosed a hemorrhoidal prolapse suggesting medical therapy. For the persistence of symptoms she comes to our service from emergency attention. Inspection and digital rectal examination revealed an anal mass. CT scan was performed showing a large anal mass involving half anal circumference. Histologic samples showed an epithelial proliferation compatible with a squamous carcinoma. Oncological consult was requested and a chemo-radiotherapy treatment was proposed. This case report highlights the difficulty when physicians assess patients with anorectal complaints in differentiating anal cancer from benign disease, presumably because symptoms are similar. Primary care physicians must maintain a high index of suspicion of cancer in high-risk population. Sensitization of these colleagues is required since digital rectal examination is of inestimable value to verify the presence of a rectal or an anal mass. PMID:27734798

    Vaginal prolapse is the protrusion of edematous vaginal tissue into and through the opening of the vulva occurring during the pro-oestrus and oestrus stages of the sexual cycle. True vaginal prolapse may occur near parturition, as the concentration of serum progesterone declines and the concentration of serum oestrogen increases. In a bitch, true vaginal prolapse is a very rare condition. This case report describes an 18-month-old crossbreed bitch, weighing 40 kg presented with type III vaginal prolapse. The patient had developed vaginal prolapse after receiving oestrogen in order to oestrus induction. Subsequent to unsuccessful attempts for repositioning, ovariohysterectomy (OHE), circumferential excision of the prolapsed tissue and finally vulvoplasty were performed. There was no evidence of recurrence of the prolapse during 30 days after surgery. This case report describes type III vaginal prolapse as an unusual side effect of oestrus induction hormonal therapy in the bitch.

    Epidemiological studies have identified increased colorectal cancer (CRC) risk with high red meat (HRM) intakes, whereas dietary fibre intake appears to be protective. In the present study, we examined whether a HRM diet increased rectal O(6)-methyl-2-deoxyguanosine (O(6)MeG) adduct levels in healthy human subjects, and whether butyrylated high-amylose maize starch (HAMSB) was protective. A group of twenty-three individuals consumed 300 g/d of cooked red meat without (HRM diet) or with 40 g/d of HAMSB (HRM+HAMSB diet) over 4-week periods separated by a 4-week washout in a randomised cross-over design. Stool and rectal biopsy samples were collected for biochemical, microbial and immunohistochemical analyses at baseline and at the end of each 4-week intervention period. The HRM diet increased rectal O(6)MeG adducts relative to its baseline by 21% (P < 0.01), whereas the addition of HAMSB to the HRM diet prevented this increase. Epithelial proliferation increased with both the HRM (P < 0.001) and HRM + HAMSB (P < 0.05) diets when compared with their respective baseline levels, but was lower following the HRM + HAMSB diet compared with the HRM diet (P < 0.05). Relative to its baseline, the HRM + HAMSB diet increased the excretion of SCFA by over 20% (P < 0.05) and increased the absolute abundances of the Clostridium coccoides group (P < 0.05), the Clostridium leptum group (P < 0.05), Lactobacillus spp. (P < 0.01), Parabacteroides distasonis (P < 0.001) and Ruminococcus bromii (P < 0.05), but lowered Ruminococcus torques (P < 0.05) and the proportions of Ruminococcus gnavus, Ruminococcus torques and Escherichia coli (P < 0.01). HRM consumption could increase the risk of CRC through increased formation of colorectal epithelial O(6)MeG adducts. HAMSB consumption prevented red meat-induced adduct formation, which may be associated with increased stool SCFA levels and/or changes in the microbiota composition.

    The main evidences of epidemiology, diagnostic imaging, pathology, surgery, radiotherapy, chemotherapy and follow-up are reviewed to optimize the routine treatment of rectal cancer according to a multidisciplinary approach. This paper reports on the knowledge shared between different specialists involved in the design and management of the multidisciplinary ESTRO Teaching Course on Rectal Cancer. The scenario of ongoing research is also addressed. In this time of changing treatments, it clearly appears that a common standard for large heterogeneous patient groups have to be substituted by more individualised therapies based on clinical-pathological features and very soon on molecular and genetic markers. Only trained multidisciplinary teams can face this new challenge and tailor the treatments according to the best scientific evidence for each patient.

    Cryptosporidium infection was associated with colitis and cystitis in 2 green iguanas (Iguana iguana). The disease was characterized by a chronic clinical course of cloacal prolapses and cystitis. Histological examination of the gut and urinary bladder showed numerous Cryptosporidium developmental stages on the surface of the epithelium with mixed inflammatory response in the lamina propria. Cryptosporidium oocysts were visualised in a cytological preparation of the faeces. Based on the small subunit ribosomal RNA gene the cryptosporidia were characterized as belonging to the intestinal cryptosporidial lineage, but not to Cryptosporidium saurophilum or Cryptosporidium serpentis species.

    Body temperature is a common physiologic parameter measured in both clinical and research settings, with rectal thermometry being implied as the ‘gold standard.’ However, rectal thermometry usually requires physical or chemical restraint, potentially causing falsely elevated readings due to animal stress. A less stressful method may eliminate this confounding variable. The current study compared 2 types of digital rectal thermometers—a calibrated digital thermometer and a common digital thermometer—with an implantable subcutaneous transponder microchip. Microchips were implanted subcutaneously between the shoulder blades of 16 ferrets (8 male, 8 female), and temperatures were measured twice from the microchip reader and once from each of the rectal thermometers. Results demonstrated the microchip temperature readings had very good to good correlation and agreement to those from both of the rectal thermometers. This study indicates that implantable temperature-sensing microchips are a reliable alternative to rectal thermometry for monitoring body temperature in ferrets. PMID:27177569

    Background: Pelvic organ prolapse (POP) is a major health concern that affects women. Surgeons have increasingly used prosthetic meshes to correct POP. However, the most common used is synthetic mesh, and absorbable mesh is less reported. This research aimed to evaluate the clinical effectiveness of porcine small intestinal submucosa (SIS). Methods: Consecutive forty POP patients who met the inclusion criteria underwent pelvic reconstruction surgery with SIS between March 2012 and December 2013. The patients’ clinical characteristics were recorded preoperatively. Surgical outcomes, measured by objective and subjective success rates, were investigated. We evaluated the quality of life (QOL) using the Pelvic Floor Distress Inventory-20 (PFDI-20) and the Pelvic Floor Impact Questionnaire-7 (PFIQ-7). Sexual QOL was assessed by the Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire-12 (PISQ-12). Results: At postoperative 12 months, the subjective recurrence rate (7.5%) was much lower than the objective recurrence rate (40.0%). Postoperatively, no erosion was identified. One underwent a graft release procedure because of urinary retention, and one had anus sphincter reconstruction surgery due to defecation urgency. Another experienced posterior vaginal wall infection where the mesh was implanted, accompanied by severe vaginal pain. Estrogen cream relieved the pain. One patient with recurrence underwent a secondary surgery with Bard Mesh because of stage 3 anterior vaginal wall prolapse. Scoring system of PFDI-20 was from 59.150 ± 13.143 preoperatively to 8.400 ± 4.749 postoperatively and PFIQ-7 was from 73.350 ± 32.281 to 7.150 ± 3.110, while PISQ-12 was from 15.825 ± 4.050 to 12.725 ± 3.471. Conclusions: QOL and the degree of subjective satisfaction were significantly improved postoperatively. Anterior repair deserves more attention because of the higher recurrence rate. The long-term follow-up of the patient is warranted to draw firm

    Abdominoperineal resections for rectal carcinoma are being performed with decreasing frequency in favor of sphincter-saving resections. It remains, however, to be unequivocally demonstrated that sphincter preservation has not resulted in compromised local disease control, disease-free survival, and survival. Accordingly, it is the specific aim of this endeavor to compare local recurrence, disease-free survival, and survival in patients with Dukes' B and C rectal cancer undergoing curative abdominoperineal resection or sphincter-saving resection. For the purpose of this study, 232 patients undergoing abdominoperineal resection and 181 subjected to sphincter-saving resections were available for analysis from an NSABP randomized prospective clinical trial designed to ascertain the efficacy of adjuvant therapy in rectal carcinoma (protocol R-01). The mean time on study was 48 months. Analyses were carried out comparing the two operations according to Dukes' class, the number of positive nodes, and tumor size. The only significant differences in disease-free survival and survival were observed for the cohort characterized by greater than 4 positive nodes and were in favor of patients treated with sphincter-saving resections. A patient undergoing sphincter-saving resection was 0.62 times as likely to sustain a treatment failure as a similar patient undergoing abdominoperineal resection (p = 0.07) and 0.49 times as likely to die (p = 0.02). The inability to demonstrate an attenuated disease-free survival and survival for patients treated with sphincter-saving resection was in spite of an increased incidence of local recurrence (anastomotic and pelvic) observed for the latter operation when compared to abdominoperineal resection (13% vs. 5%). A similar analysis evaluating the length of margins of resection in patients undergoing sphincter-preserving operations indicated that treatment failure and survival were not significantly different in patients whose distal resection

    Pelvic organ prolapse is a vaginal protrusion of female pelvic organs. It has high prevalence worldwide and represents a great burden to the economy. The pathophysiology of pelvic organ prolapse is multifactorial and includes genetic predisposition, aberrant connective tissue, obesity, advancing age, vaginal delivery and other risk factors. Owing to the long course prior to patients becoming symptomatic and ethical questions surrounding human studies, animal models are necessary and useful. These models can mimic different human characteristics – histological, anatomical or hormonal, but none present all of the characteristics at the same time. Major animal models include knockout mice, rats, sheep, rabbits and nonhuman primates. In this article we discuss different animal models and their utility for investigating the natural progression of pelvic organ prolapse pathophysiology and novel treatment approaches. PMID:22707980

    AIM To highlight the rising trend in hospital presentation of foreign bodies retained in the rectum over a 5-year period. METHODS Retrospective review of the cases of retained rectal foreign bodies between 2008 and 2012 was performed. Patients’ clinical data and yearly case presentation with data relating to hospital episodes were collected. Data analysis was by SPSS Inc. Chicago, IL, United States. RESULTS Twenty-five patients presented over a 5-year period with a mean age of 39 (17-62) years and M: F ratio of 2:1. A progressive rise in cases was noted from 2008 to 2012 with 3, 4, 4, 6, 8 recorded patients per year respectively. The majority of the impacted rectal objects were used for self-/partner-eroticism. The commonest retained foreign bodies were sex vibrators and dildos. Ninty-six percent of the patients required extraction while one passed spontaneously. Two and three patients had retrieval in the Emergency Department and on the ward respectively while 19 patients needed examination under anaesthesia for extraction. The mean hospital stay was 19 (2-38) h. Associated psychosocial issues included depression, deliberate self-harm, illicit drug abuse, anxiety and alcoholism. There were no psychosocial problems identified in 15 patients. CONCLUSION There is a progressive rise in hospital presentation of impacted rectal foreign bodies with increasing use of different objects for sexual arousal. PMID:27830039

    Solitary rectal ulcer syndrome is a rare benign disorder that has a wide range of clinical presentations and variable endoscopic findings which makes it difficult to diagnose and treat. The clinical and endoscopic picture in this condition can also mimic malign ulceration, malignancy or Crohn's disease. Behçet's disease can affect the gastrointestinal tract. However to the best of our knowledge, no case with solitary rectal ulceration has been reported so far in literature. We herein present a patient diagnosed with Behçet's disease admitted to our clinic with rectal bleeding due to solitary rectal ulceration.

    Central descent due to a level 1 defect is a main component in pelvic organ prolapse (POP) reconstructive surgery, whether for symptomatic apical prolapse or for the prolapse repair of other compartments. A recent growth in the rate of native tissue repair procedures for POP, following the US Food and Drug Administration (FDA) warnings regarding the safety and efficacy of synthetic meshes, requires a re-evaluation of these procedures. The safety, efficacy, and determination of the optimal surgical approach should be the center of attention. Functional outcome measures and patient-centered results have lately gained importance and received focus. A comprehensive literature review was performed to evaluate objective and subjective outcomes of apical prolapse native tissue repair, with a special focus on studies reporting impact on patients' functional outcomes, quality of life, and satisfaction. We performed a MEDLINE search for articles in the English language by using the following key words: apical prolapse, sacrospinous ligament fixation, uterosacral ligament suspension, sacral colpopexy, McCall culdoplasty, iliococcygeus vaginal fixation, and functional outcomes. We reviewed references as well. Despite a prominent shortage of studies reporting standardized prospective outcomes for native tissue repair interventions, we noted a high rate of safety and efficacy, with a low complication rate for most procedures and low recurrence or re-treatment rates. The objective and subjective results of different procedures are reviewed. Functional outcomes of native tissue repair procedures have not been studied sufficiently, though existing data present those procedures as favorable and not categorically inferior to sacrocolpopexy.

    As the field of reconstructive pelvic surgery continues to evolve, with descriptions of new procedures to repair pelvic organ prolapse, it remains imperative to maintain a functional understanding of pelvic floor anatomy and support. The goal of this review was to provide a focused, conceptual approach to differentiating anatomic defects contributing to prolapse in the various compartments of the vagina. Rather than provide exhaustive descriptions of pelvic floor anatomy, basic pelvic floor anatomy is reviewed, new and historical concepts of pelvic floor support are discussed, and relevance to the surgical management of specific anatomic defects is addressed.

    A 51-year-old male drove into a ditch on his scooter. Immediately after the trauma the patient complained of neck pain and decreased ability to feel and move his extremities. An initial trauma computed tomography (CT) of the columna showed normal conditions. Because the patient had neurological deficiencies, magnetic resonance imaging of the columna was performed 12 days later, and a disc prolapse at the C3/C4 level with spinal cord compression was visible. Despite decompression the patient did not recover. Traumatic cervical disc prolapse is a rare and positionally dangerous condition, which can be present despite a CT showing normal conditions.

    An evaluation of rectal, rectosigmoidal, and bladder doses from intracavitary brachytherapy in carcinoma of the cervix has been initiated on a routine basis in an effort to obtain the optimum radiotherapeutic dose. Contrast radiography on a radiotherapy simulator is used to image the rectum and bladder, and dose rates are determined at predesignated reference points with the aid of computer calculated dose distributions. Forty-three patients have been reviewed in order to ascertain the correlation between radiation injury and dose at reference points in the rectum and bladder. In a related study involving 77 patients, the doses at points A and B and the prescription in mghr were analyzed in relation to radiation injury. There was no apparent association between the incidence of radiation injury in either the mghr prescription or the doses at points A or B. Computer calculations were supplemented with in vivo and in vitro thermoluminescent dosimeter (TLD) measurements. We conclude that routine contrast radiography of the rectum and the bladder with dose calculations at selected reference points provides important information for optimizing radiotherapy in carcinoma of the cervix without a significant increase in treatment planning effort or patient discomfort.

    A 55-year-old woman, known with multiple endocrine neoplasia (MEN) type 1, had rectal bleeding and later haematemesis but colonoscopy and gastroduodenoscopy revealed no abnormalities. Due to the normal results for serum gastrin concentration, gastroduodenoscopy and CT scanning of the pancreas, Zollinger-Ellison syndrome was considered to be less likely. Yet the diagnosis could be established on the basis of persistent symptoms and a positive somatostatin receptor scintigraphy. The patient was treated with high doses of a proton pump inhibitor and temporary tube feeding due to weight loss. Follow-up will take place at the endocrinology outpatients' department. Zollinger-Ellison syndrome is a relatively common feature of patients with MEN-1. The diagnosis and localisation of the gastrinoma can be difficult: serum gastrin concentrations can be normal and the sensitivity of CT scanning is low. The primary aim of treating gastrinoma is to control gastric acid hypersecretion by means of high doses of a proton pump inhibitor. The question as to whether surgery is indicated remains controversial.

    In order to determine the predictive value for ventricular arrhythmias of ventricular late potentials (LP) in mitral valve prolapse (MVP) the authors performed high amplification signal-averaging ECG (SA) and 24 hours ambulatory ECG (Holter) monitoring in 68 consecutive patients (34 men, 34 women, average age 48 +/- 17.7 years) with echocardiographically diagnosed MVP. Patients with bundle branch block or associated cardiac disease were excluded. Echocardiography showed 26 patients to have floppy mitral valves (38.2%), 50 patients to have posterior deplacement > or = 5 mm of the mitral valves in systole (73.5%) and 35 patients to have mitral regurgitation (51.4%). Holter monitoring showed 17 patients without ventricular extrasystoles (VES), 15 had Lown Grade I, 6 had Lown Grade II, 3 had Lown Grade III, 15 had Lown Grade IV A and 12 had Lown Grade IV B ventricular arrhythmias. Therefore, 30 patients had complex ventricular arrhythmias (> or = Lown Grade III) and 13 patients had spontaneous non-sustained ventricular tachycardia (NSVT) (one patient had NSVT on resting ECG but not on Holter monitoring). Eighteen patients had LP (26.5%). The incidence of complex ventricular arrhythmias was higher in patients with mitral regurgitation (62.8% versus 27.7%; p < 0.005) whereas the incidence of NSVT was not significantly different (25.7% versus 17.1%; p = 0.15). On the other hand, the frequency of complex ventricular arrhythmias was not significantly different in the presence or absence of LP (61.1% versus 40%: NS) whereas the incidence of NSVT was higher in patients with LP (44.4% versus 10%; p < 0.005).(ABSTRACT TRUNCATED AT 250 WORDS)

    Men and women engaged in unprotected receptive anal intercourse (RAI) are at higher risk of acquiring HIV from infected partners. The implementation of preventive strategies is urgent and rectal microbicides may be a useful tool in reducing the sexual transmission of HIV. However, pre-clinical and first clinical trials have been able to identify limitations of candidate products, mostly related with safety issues, which can in turn enhance viral infection. Indeed, the development of suitable formulations for the rectal delivery of promising antiretroviral drugs is not an easy task, and has been mostly based on products specifically intended for vaginal delivery, but these have been shown to provide sub-optimal outcomes when administered rectally. Research and development in the rectal microbicide field are now charting their own path and important information is now available. In particular, specific formulation requirements of rectal microbicide products that need to be met have just recently been acknowledged despite additional work being still required. Desirable rectal microbicide product features regarding characteristics such as pH, osmolality, excipients, dosage forms, volume to be administered and the need for applicator use have been studied and defined in recent years, and specific guidance is now possible. This review provides a synopsis of the field of rectal microbicides, namely past and ongoing clinical studies, and details on formulation and drug delivery issues regarding the specific development of rectal microbicide products. Also, future work, as required for the advancement of the field, is discussed.

    As technology gets better and better, and as clinical research provides more and more knowledge, we can extend our ambition to cure patients from cancer with restored physical health among the survivors. This increased ambition requires attention to grade 1 toxicity that decreases quality of life. It forces us to document the details of grade 1 toxicity and improve our understanding of the mechanisms. Long-term toxicity scores, or adverse events as documented during clinical trials, may be regarded as symptoms or signs of underlying survivorship diseases. However, we lack a survivorship nosology for rectal cancer survivors. Primarily focusing on radiation-induced side effects, we highlight some important observations concerning late toxicity among rectal cancer survivors. With that and other data, we searched for a preliminary survivorship-disease nosology for rectal cancer survivors. We disentangled the following survivorship diseases among rectal cancer survivors: low anterior resection syndrome, radiation-induced anal sphincter dysfunction, gut wall inflammation and fibrosis, blood discharge, excessive gas discharge, excessive mucus discharge, constipation, bacterial overgrowth, and aberrant anatomical structures. The suggested survivorship nosology may form the basis for new instruments capturing long-term symptoms (patient-reported outcomes) and professional-reported signs. For some of the diseases, we can search for animal models. As an end result, the suggested survivorship nosology may accelerate our understanding on how to prevent, ameliorate, or eliminate manifestations of treatment-induced diseases among rectal cancer survivors.

    BACKGROUND Although synthetic mesh is associated with superior anatomic outcomes for the repair of pelvic organ prolapse, the benefits of mesh have been questioned because of the relatively high complication rates. To date, the mechanisms that result in such complications are poorly understood, yet the textile characteristics of mesh products are believed to play an important role. Interestingly, the pore diameter of synthetic mesh has been shown to impact the host response after hernia repair greatly, and such findings have served as design criteria for prolapse meshes, with larger pores viewed as more favorable. Although pore size and porosity are well-characterized before implantation, the changes in these textile properties after implantation are unclear; the application of mechanical forces has the potential to greatly alter pore geometries in vivo. Understanding the impact of mechanical loading on the textile properties of mesh is essential for the development of more effective devices for prolapse repair. OBJECTIVE The objective of this study was to determine the effect of tensile loading and pore orientation on mesh porosity and pore dimensions. STUDY DESIGN In this study, the porosity and pore diameter of 4 currently available prolapse meshes were examined in response to uniaxial tensile loads of 0.1, 5, and 10 N while mimicking clinical loading conditions. The textile properties were compared with those observed for the unloaded mesh. Meshes included Gynemesh PS (Ethicon, Somerville, NJ), UltraPro (Artisyn; Ethicon), Restorelle (Coloplast, Minneapolis, MN), and Alyte Y-mesh (Bard, Covington, GA). In addition to the various pore geometries, 3 orientations of Restorelle (0-, 5-, 45-degree offset) and 2 orientations of UltraPro (0-, 90-degree offset) were examined. RESULTS In response to uniaxial loading, both porosity and pore diameter dramatically decreased for most mesh products. The application of 5 N led to reductions in porosity for nearly all groups

  7. Early prediction of histopathological response of rectal tumors after one week of preoperative radiochemotherapy using 18 F-FDG PET-CT imaging. A prospective clinical study

    PubMed Central

    2012-01-01

    Background Preoperative radiochemotherapy (RCT) is standard in locally advanced rectal cancer (LARC). Initial data suggest that the tumor’s metabolic response, i.e. reduction of its 18 F-FDG uptake compared with the baseline, observed after two weeks of RCT, may correlate with histopathological response. This prospective study evaluated the ability of a very early metabolic response, seen after only one week of RCT, to predict the histopathological response to treatment. Methods Twenty patients with LARC who received standard RCT regimen followed by radical surgery participated in this study. Maximum standardized uptake value (SUV-MAX), measured by PET-CT imaging at baseline and on day 8 of RCT, and the changes in FDG uptake (ΔSUV-MAX), were compared with the histopathological response at surgery. Response was classified by tumor regression grade (TRG) and by achievement of pathological complete response (pCR). Results Absolute SUV-MAX values at both time points did not correlate with histopathological response. However, patients with pCR had a larger drop in SUV-MAX after one week of RCT (median: -35.31% vs −18.42%, p = 0.046). In contrast, TRG did not correlate with ΔSUV-MAX. The changes in FGD-uptake predicted accurately the achievement of pCR: only patients with a decrease of more than 32% in SUV-MAX had pCR while none of those whose tumors did not show any decrease in SUV-MAX had pCR. Conclusions A decrease in ΔSUV-MAX after only one week of RCT for LARC may be able to predict the achievement of pCR in the post-RCT surgical specimen. Validation in a larger independent cohort is planned. PMID:22853868

    Four cases of anorexia nervosa recently encountered were reported in respect to their cardiovascular manifestations including prolapse of the cardiac valves and other poorly recognized cardiac findings. All four patients, aged 13 to 32 years, were women and had marked emaciation (35 to 44% weight loss of the ideal body weight) with typical hormone abnormalities. Chest radiographs showed a small cardiac shadow, and sinus bradycardia with low voltage was present in their electrocardiograms. One case, 13-year-old, had a mid-systolic click and occasionally a late systolic murmur, and also an abdominal continuous hum. Echocardiography including two-dimensional color flow-mapping disclosed mitral valve prolapse in all, and tricuspid valve prolapse in two. Mild to moderate pericardial effusion was noted in all between the right ventricle and diaphragm, and pericardiocentesis in one case had no effect on the valve movements. No inflammatory changes were observed in the specimen of the pericardium and also of the fluid. An association of mitral valve prolapse and anerexia nervosa was discussed based on the previous studies, but the final conclusion remains unknown.

    The standard adjuvant treatment for cT3 and/or N+ rectal cancer is preoperative chemoradiation. However, there are many controversies regarding this approach. These include the role of short course radiation, whether postoperative adjuvant chemotherapy necessary for all patients and whether the type of surgery after chemoradiation should be based on the response rate. More accurate imaging techniques and/or molecular markers may help identify patients with positive pelvic nodes to reduce the chance of overtreatment with preoperative therapy. Will more effective systemic agents both improve the results of radiation as well as modify the need for pelvic radiation? These questions and others remain active areas of clinical investigation.

    The two conventional treatments for clinically resectable rectal cancer are surgery followed by postoperative combined modality therapy and preoperative combined modality therapy followed by surgery and postoperative chemotherapy. Preoperative therapy (most commonly combined modality therapy) has gained acceptance as a standard adjuvant therapy. The potential advantages of the preoperative approach include decreased tumor seeding, less acute toxicity, increased radiosensitivity due to more oxygenated cells, and enhanced sphincter preservation. There are a number of new chemotherapeutic agents that have been developed for the treatment of patients with colorectal cancer. Phase I/II trials examining the use of new chemotherapeutic agents in combination with pelvic radiation therapy are in progress.

    Current weaponry possesses unobserved new, biodynamic wounding effects. For many victims, high velocity, large shell fragments have resulted in massive lower jaw "chopped off" hard and soft tissues injuries accompanied by tongue prolapse. The management challenges begin with lifesaving which is possibly complicated by airway compromise, severe hemorrhage, massive lower jaw loss, and a prolapsed tongue. Consequently, the goal shall be "No patient should die from massive facial tissue injuries alone". That is, if feasible, sensible, lifesaving techniques are applied at the appropriate time. Following general condition stabilization, the surgical management steps of massive lower jaw tissue loss should begin with immediate lost tissue reconstruction. Seventeen cases were selected from an unquantified number patients who had massive mandibular tissue losses in which the tongue, surprisingly, remained intact. In these cases, definitive, early scaffolding stabilization was accomplished by joining the remaining two lower jaw intact segments. The successful procedure consists of using a 2 mm horseshoe shaped Kirschner wire bridging the gap of the mandibular arch which effectively is used as a "scaffold" for rebuilding the soft tissue. Proper, initial, surgical management resulted in protecting lacerated tissue, diminishing subsequent morbidity and disfigurement, preventing a prolapsed tongue and preserving the intact tissues physiological functions. As the spectrum of injuries continues to evolve the clinical characterization of the severity of facial wounds need an expanded classification, appropriate to massive facial injuries. It is suggested it has the following descriptors: blast, penetration, perforation, avulsions and "chopping off" (BPPAC).

    Introduction Lumbar radiculopathy is a major health problem often treated by surgery or guided lumbar epidural steroids for pain relief. We have used Platelet Rich Plasma (PRP) a novel therapeutic tool of autologous nature that has emerged strongly in recent years to treat patients of prolapsed intervertebral disc. Aim To evaluate the efficacy of PRP via interlaminar epidural route in treatment of pain in patients with prolapsed inter vertebral disc. Materials and Methods Ten patients were injected with five ml of autologous platelet rich plasma under fluoroscopic guidance via interlaminar lumbar epidural injection into area of affected nerve root. They were followed using VAS (Visual Analogue Scale), SLRT (Straight Leg Raising Test) and MODQ (Modified Oswestry Disability Questionnaire) for clinical improvement. Results Patients who had received epidural injections of autologous PRP showed improvements in their scores of evaluation tools. Improvement was sustained during the 3 month study period and was not associated with any complications. Conclusion Autologous PRP can be considered as a good alternative to epidural steroids and surgery in management of patients with chronic prolapsed intervertebral disc. PMID:27790553

    Robotic technology, which has recently been introduced to the field of surgery, is expected to be useful, particularly in treating rectal cancer where precise manipulation is necessary in the confined pelvic cavity. Robotic surgery overcomes the technical drawbacks inherent to laparoscopic surgery for rectal cancer through the use of multi-articulated flexible tools, three-dimensional stable camera platforms, tremor filtering and motion scaling functions, and greater ergonomic and intuitive device manipulation. Assessments of the feasibility and safety of robotic surgery for rectal cancer have reported similar operation times, blood loss during surgery, rates of postoperative morbidity, and circumferential resection margin involvement when compared with laparoscopic surgery. Furthermore, rates of conversion to open surgery are reportedly lower with increased urinary and male sexual functions in the early postoperative period compared with laparoscopic surgery, demonstrating the technical advantages of robotic surgery for rectal cancer. However, long-term outcomes and the cost-effectiveness of robotic surgery for rectal cancer have not been fully evaluated yet; therefore, large-scale clinical studies are required to evaluate the efficacy of this new technology.

    A randomized phase II/III trial was started in May 2015 comparing perioperative versus postoperative chemotherapy with modified infusional fluorouracil and folinic acid with oxaliplatin for lower rectal cancer patients with suspected lateral pelvic node metastasis. The standard arm is total mesorectal excision or tumor-specific mesorectal excision with lateral pelvic node dissection (LND) followed by postoperative chemotherapy (modified infusional fluorouracil and folinic acid with oxaliplatin; 12 cycles). The experimental (perioperative chemotherapy) arm is six courses of modified infusional fluorouracil and folinic acid with oxaliplatin before and six courses after total mesorectal excision with lateral pelvic node dissection. The aim of this trial is to confirm the superiority of perioperative chemotherapy. A total of 330 patients will be enrolled over 7 years. The primary endpoint in Phase II part is proportion of R0 resection and that in Phase III part is overall survival. Secondary endpoints are progression-free survival, local progression-free survival, etc. This trial has been registered in the UMIN Clinical Trials Registry as UMIN000017603 [http://www.umin.ac.jp/ctr/index-j.htm].

    Fournier’s gangrene (FG) is a rapid progressive bacterial infection that involves the subcutaneous fascia and part of the deep fascia but spares the muscle in the scrotal, perianal and perineal region. The incidence has increased dramatically, while the reported incidence of rectal cancer-induced FG is unknown but is extremely low. Pathophysiology and clinical presentation of rectal cancer-induced FG per se does not differ from the other causes. Only rectal cancer-specific symptoms before presentation can lead to the diagnosis. The diagnosis of rectal cancer-induced FG should be excluded in every patient with blood on digital rectal examination, when urogenital and dermatological causes are excluded and when fever or sepsis of unknown origin is present with perianal symptomatology. Therapeutic options are more complex than for other forms of FG. First, the causative rectal tumor should be removed. The survival of patients with rectal cancer resection is reported as 100%, while with colostomy it is 80%. The preferred method of rectal resection has not been defined. Second, oncological treatment should be administered but the timing should be adjusted to the resolution of the FG and sometimes for the healing of plastic reconstructive procedures that are commonly needed for the reconstruction of large perineal, scrotal and lower abdominal wall defects.

  18. Local management of rectal neoplasia.

    2008-11-01

    The treatment of rectal neoplasia, whether benign or malignant, challenges the surgeon. The challenge in treating rectal cancer is selecting the proper approach for the appropriate patient. In a small number of rectal cancer patients local excision may be the best approach. In an attempt to achieve two goals-cure of disease with a low rate of local failure and maintenance of function and quality of life-multiple approaches can be utilized. The key to obtaining a good outcome for any one patient is balancing the competing factors that impact on these goals. Any effective treatment aimed at controlling rectal cancer in the pelvis must take into account the disease in the bowel wall itself and the disease, or potential disease, in the mesorectum. The major downside of local excision techniques is the potential of leaving untreated disease in the mesorectum. Local management techniques avoid the potential morbidity, mortality, and functional consequences of a major abdominal radical resection and are thus quite effective in achieving the maintenance of function and quality of life goal. The issue for the transanal techniques is how they fare in achieving the first goal-cure of the cancer while keeping local recurrence rates to an absolute minimum. Without removing both the rectum and the mesorectum there is no completely accurate way to determine whether a rectal cancer has moved outside the bowel wall, so any decision on local management of a rectal neoplasm is a calculated risk. For benign neoplasia, the challenge is removing the lesion without having to resort to a major abdominal procedure.

    AIM To investigate feasibility and outcome of abdominal-sacral resection for treatment of locally recurrent rectal adenocarcinoma. METHODS A population of patients who underwent an abdominal-sacral resection for posterior recurrent adenocarcinoma of the rectum at the National Cancer Institute of Milano, between 2005 and 2013, is considered. Retrospectively collected data includes patient characteristics, treatment and pathology details regarding the primary and the recurrent rectal tumor surgical resection. A clinical and instrumental follow-up was performed. Surgical and oncological outcome were investigated. Furthermore an analytical review of literature was conducted in order to compare our case series with other reported experiences. RESULTS At the time of abdomino-sacral resection, the mean age of patients was 55 (range, 38-64). The median operating time was 380 min (range, 270-480). Sacral resection was performed at S2/S3 level in 3 patients, S3/S4 in 3 patients and S4/S5 in 4 patients. The median operating time was 380 ± 58 min. Mean intraoperative blood loss was 1750 mL (range, 200-680). The median hospital stay was 22 d. Overall morbidity was 80%, mainly type II complication according to the Clavien-Dindo classification. Microscopically negative margins (R0) is obtained in all patients. Overall 5-year survival after first surgical procedure is 60%, with a median survival from the first surgery of 88 ± 56 mo. The most common site of re-recurrence was intrapelvic. CONCLUSION Sacral resection represents a feasible approach to posterior rectal cancer recurrence without evidence of distant spreading. An accurate staging is essential for planning the best therapy. PMID:28070232

    A 3-year-old girl presented with a prolapsed cutaneous vesicostomy, and symptoms and signs of acute intestinal obstruction. The vesicostomy had been performed when she was 19 months old for bilateral vesicoureteral reflux. Postoperatively, prolapse of the bladder from the stoma occurred almost daily. The prolapsed part retracted naturally when the patient was relaxed and reclining. Intestinal obstruction was due to strangulated herniation of the bowel into the prolapsed bladder via the stoma of vesicostomy. Treatment consisted of manual reduction and the stoma of the vesicostomy was revised with the patient under general anesthesia.

The female was presented with a history of recent parturition, with delivery of four healthy puppies that were normally tended and nursed. The situation developed after an uneventfully pregnancy, and no direct causative factor was identified. The duration of the prolapse was unknown, but considered to be recent because of the swollen reddish appearance of the tubular everted mass. No foetus was found in the uterus or the abdominal cavity. The female was presented in good physical condition, without signs of shock or haemorrhage. During surgical treatment, the uterus was replaced to its normal position followed by ovary-hysterectomy at 12 h from admittance.

    Cutis laxa (CL) is an extremely inherited or acquired connective tissue disorder characterised by a markedly reduced systemic elastin content. Genital abnormalities in patients with CL have been rarely reported. We report such a case in a 48-year-old CL patient affected by genital prolapse, focusing on immunohistological and molecular biology assessment of elastin and collagen type I, III, VI content in the main uterine ligaments. The woman was referred to our department for the onset of a rapidly progressing genital prolapse and urinary incontinence. The patient underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy and sacrocolpopexy. Punch biopsies from both cardinal and uterosacral ligaments revealed a dramatic reduction in elastin and an increase in collagen type VI content. The present report seems to underline the central role exerted primarily by elastin in the supportive connective tissue and might contribute to the knowledge of extracellular matrix abnormalities at the basis of genital abnormalities in CL patients.

  3. Update and Debate Issues in Surgical Treatment of Middle and Low Rectal Cancer

    Kim, Min Sung; AL-Asari, Sami F.

    2012-01-01

    Based on a review of the literature, this paper provides an update on surgical treatment of middle and low rectal cancer and discusses issues of debate surrounding that treatment. The main goal of the surgical treatment of rectal cancer is radical resection of the tumor and surrounding lymphatic tissue. Local excision of early rectal cancer can be another treatment option, in which the patient can avoid possible complications related to radical surgery. Neoadjuvant chemoradiation therapy (CRT) has been recommended for patients with cT3-4N0 or any T N+ rectal cancer because CRT shows better local control and less toxicity than adjuvant CRT. However, recent clinical trials showed promising results for local excision after neoadjuvant CRT in selected patients with low rectal cancer. In addition, the "wait and see" concept is another modality that has been reported for the management of tumors that show complete clinical remission after neoadjuvant CRT. Although radical surgery for middle and low rectal cancer is the cornerstone therapy, an ultralow anterior resection with or without intersphincteric resection (ISR) has become an alternative standard surgical method for selected patients. Many studies have reported on the oncological safety of the ISR, but few of them have addressed the issue the functional outcome. Furthermore, an abdominoperineal resection (APR) has problems with high rates of tumor perforations and positive circumferential resection margins, and those factors have contributed to its having a high rate of local recurrence and a poor survival rate for rectal cancer compared with sphincter-saving procedures. Recently, great efforts have been made to reduce these problems, and the total levator excision or the extended APR concept has emerged. Surgical management for low rectal cancer should aim to radically excise the tumor and to preserve as much of the sphincter function as possible by using multidisciplinary approaches. However, further prospective

    There are still many doubts in the literature regarding gastroesophageal mucosal prolapse (GEMP) and its clinical course. We still do not know what determines mucosal wedging in esophagogastric junction, and what is the role of the anatomy of that site. To investigate that problem we performed 120 upper digestive tract endoscopies in which a hiatal hernia was diagnosed. Patients referred to our unit with different complaints most frequently of typical or atypical gastroesophageal (GE) reflux symptoms. The aim of that study was to assess hernia dimensions in patients with and without GEMP diagnosed during endoscopy. Additionally we analyzed the type and prevalence of gastrointestinal symptoms reported by patients to confirm the observation that GEMP symptoms differ from gastroesophageal reflux disease (GERD) symptoms.

    Understanding proteomic differences underlying the different phenotypic classes of colon and rectal carcinoma is important and may eventually lead to a better assessment of clinical behavior of these cancers. We here present a comprehensive description of the proteomic data obtained from 90 colon and rectal carcinomas previously subjected to genomic analysis by The Cancer Genome Atlas (TCGA). Here, the primary instrument files and derived secondary data files are compiled and presented in forms that will allow further analyses of the biology of colon and rectal carcinoma. We also discuss new challenges in processing these large proteomic datasets for relevant proteins and protein variants.

  6. Making sense of urodynamic studies for women with urinary incontinence and pelvic organ prolapse: a urogynecology perspective.

    2012-08-01

    The support for routine urodynamic testing in the management of women with urinary incontinence or pelvic organ prolapse is eroding. The reasons for this change largely reflect the growing evidence that urodynamic testing in this context renders little additional information over basic office assessment. The clinical features of urodynamic testing and its diagnostic and prognostic precision and accuracy are all problematic. As our understanding of female lower urinary tract dysfunction improves, the inadequacy of urodynamic testing to meaningfully improve patient and clinician decision making has become more apparent.

    Secondary penile tumours from rectal carcinoma is a known clinical entity but can be missed unless carefully evaluated. We report a case of rectal adenocarcinoma with synchronous painless penile nodules. A patient presented with constipation and rectal bleeding. He had an anorectal growth as well as palpable nodules on his penis. Rectal biopsy yielded adenocarcinoma. Imaging revealed direct infiltration of tumour into the bulb of the penis as well as distal shaft lesions. Fine-needle aspiration cytology of the penile nodule showed metastatic adenocarcinoma. Diversion colostomy was performed and the patient referred for chemoradiation. Since he did not have any urinary symptoms, the penile lesions were left unaltered. Repeat imaging after concurrent chemoradiotherapy showed no response. The prognosis was explained and the patient was given palliative clinic care.

    The purpose of this study was to evaluate whether a spacer inserted in the prerectal space could reduce modeled rectal dose and toxicity rates for patients with prostate cancer treated in silico with pencil beam scanning (PBS) proton therapy. A total of 20 patients were included in this study who received photon therapy (12 with rectal spacer (DuraSeal™ gel) and 8 without). Two PBS treatment plans were retrospectively created for each patient using the following beam arrangements: (1) lateral-opposed (LAT) fields and (2) left and right anterior oblique (LAO/RAO) fields. Dose volume histograms (DVH) were generated for the prostate, rectum, bladder, and right and left femoral heads. The normal tissue complication probability (NTCP) for ≥grade 2 rectal toxicity was calculated using the Lyman-Kutcher-Burman model and compared between patients with and without the rectal spacer. A significantly lower mean rectal DVH was achieved in patients with rectal spacer compared to those without. For LAT plans, the mean rectal V70 with and without rectal spacer was 4.19 and 13.5%, respectively. For LAO/RAO plans, the mean rectal V70 with and without rectal spacer was 5.07 and 13.5%, respectively. No significant differences were found in any rectal dosimetric parameters between the LAT and the LAO/RAO plans generated with the rectal spacers. We found that ≥ 9 mm space resulted in a significant decrease in NTCP modeled for ≥grade 2 rectal toxicity. Rectal spacers can significantly decrease modeled rectal dose and predicted ≥grade 2 rectal toxicity in prostate cancer patients treated in silico with PBS. A minimum of 9 mm separation between the prostate and anterior rectal wall yields the largest benefit.

    Purpose To determine whether large rectal volume on planning computed tomography (CT) results in lower tumor regression grade (TRG) after neoadjuvant concurrent chemoradiotherapy (CCRT) in rectal cancer patients. Materials and Methods We reviewed medical records of 113 patients treated with surgery following neoadjuvant CCRT for rectal cancer between January and December 2012. Rectal volume was contoured on axial images in which gross tumor volume was included. Average axial rectal area (ARA) was defined as rectal volume divided by longitudinal tumor length. The impact of rectal volume and ARA on TRG was assessed. Results Average rectal volume and ARA were 11.3 mL and 2.9 cm². After completion of neoadjuvant CCRT in 113 patients, pathologic results revealed total regression (TRG 4) in 28 patients (25%), good regression (TRG 3) in 25 patients (22%), moderate regression (TRG 2) in 34 patients (30%), minor regression (TRG 1) in 24 patients (21%), and no regression (TRG0) in 2 patients (2%). No difference of rectal volume and ARA was found between each TRG groups. Linear correlation existed between rectal volume and TRG (p = 0.036) but not between ARA and TRG (p = 0.058). Conclusion Rectal volume on planning CT has no significance on TRG in patients receiving neoadjuvant CCRT for rectal cancer. These results indicate that maintaining minimal rectal volume before each treatment may not be necessary. PMID:27592514

    Until 2004, initial surgery and, in cases of pT3 and/or node-positive disease, postoperative chemoradiotherapy (radiation plus concurrent chemotherapy) was the conventional approach for patients with clinical T3 and/or node-positive rectal cancer. The German CAO/ARO/AIO 94 trial confirmed that, compared with preoperative chemoradiotherapy, postoperative chemoradiotherapy is associated with significantly higher local failure and toxicity rates as well as a decrease in the incidence of sphincter preservation. These data resulted in a change from postoperative to preoperative chemoradiotherapy. This shift to preoperative therapy has prompted a series of new questions regarding the multidisciplinary management of rectal cancer, including: What is the ideal neoadjuvant approach (short-course vs. combined-modality therapy)? Is postoperative adjuvant chemotherapy necessary for all patients following preoperative chemoradiotherapy? Do patients with node-negative rectal cancer require pelvic radiation? What is the ideal combined-modality regimen? Does an increase in response rate translate into improved local control and survival? And lastly, what is the benefit of novel radiation sensitization and delivery techniques? This review will address these and other questions surrounding the multidisciplinary management of rectal cancer.

    Neovaginal prolapse is a rare and distressing complication after male-to-female sexual reassignment surgery. We retrospectively analysed the prevalence of partial and total neo-vaginal prolapses after sexual reassignment surgery in our institute. During the years, two different techniques have been adopted with the aim of fixing the neovaginal cylinder. In the first, two absorbable sutures are placed at the top of the penoscrotal cylinder and fixed to the Denonvilliers fascia. In the second, two additional sutures are added from the posterior/midpoint of the flap to the prerectal fascia. We enrolled 282 consecutive transsexual patients. 65 (23.04%) out of the 282 were treated with the first technique and the following 217 (76.96%) with the last technique. In the first technique, 1 case (1.53%) of total prolapse and 7 cases (10.76%) of partial prolapse were observed, while in the other 217 patients treated with the second technique only 9 cases of partial prolapse were observed (4.14%) and no cases of total prolapse. All prolapses occurred within 6 months from the procedure. In our experience, the use of 4 stitches and a more proximal positioning of the sutures to fix the penoscrotal apex with the Denonvilliers fascia guarantees a lower risk of prolapse.

    Background Severe or complicated malaria is a medical emergency and people die as a result of delays in starting treatment. Most patients need parenteral treatment, and in primary healthcare facilities, where intravenous therapy is not available but intramuscular injections can be given, intramuscular quinine, artesunate, and artemether have been used before transporting patients to hospital. However, in rural settings with limited access to health care, intramuscular injections may also be unavailable. In these situations, rectal artesunate given prior to transfer to hospital by volunteers with little medical training, may be a feasible option. Objectives To evaluate the effects of pre-referral treatment with rectal artesunate on mortality and morbidity in people with severe malaria. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL) published in The Cochrane Library; MEDLINE; EMBASE and LILACS up to 21 May 2014. We also searched the WHO clinical trial registry platform and the metaRegister of Controlled Trials (mRCT) for ongoing trials. Selection criteria Individual or cluster-randomized controlled trials comparing pre-referral rectal artesunate with placebo or injectable antimalarials in children and children with severe malaria. Data collection and analysis Two authors independently screened titles and abstracts for potentially eligible trials, and extracted data from the included trials. Dichotomous outcomes were summarized using risk ratios (RR) and presented with 95% confidence intervals (95% CI). Where data allowed, we conducted subgroup analyses by age, trial region and whether participants were included in the trial analysis. We assessed the quality of evidence for the most important outcomes using the GRADE approach. Main results One trial met the inclusion criteria; a placebo-controlled trial of 17,826 children and adults living in rural villages in Ghana and Tanzania (Africa) and Bangladesh (Asia).

    Rectal adenocarcinoma is an important cause of cancer-related deaths worldwide, and key anatomic differences between the rectum and the colon have significant implications for management of rectal cancer. Many advances have been made in the diagnosis and management of rectal cancer. These include clinical staging with imaging studies such as endorectal ultrasound and pelvic magnetic resonance imaging, operative approaches such as transanal endoscopic microsurgery and laparoscopic and robotic assisted proctectomy, as well as refined neoadjuvant and adjuvant therapies. For stage II and III rectal cancers, combined chemoradiotherapy offers the lowest rates of local and distant relapse, and is delivered neoadjuvantly to improve tolerability and optimize surgical outcomes, particularly when sphincter-sparing surgery is an endpoint. The goal in rectal cancer treatment is to optimize disease-free and overall survival while minimizing the risk of local recurrence and toxicity from both radiation and systemic therapy. Optimal patient outcomes depend on multidisciplinary involvement for tailored therapy. The successful management of rectal cancer requires a multidisciplinary approach, with the involvement of enterostomal nurses, gastroenterologists, medical and radiation oncologists, radiologists, pathologists and surgeons. The identification of patients who are candidates for combined modality treatment is particularly useful to optimize outcomes. This article provides an overview of the diagnosis, staging and multimodal therapy of patients with rectal cancer for primary care providers. PMID:26167068

    Rectal affection accounts for 30% of colorectal cancer. The standard of treatment is surgical resection, which often is curative. For superior and middle-rectal involvement, low anterior resection (LAR) is the preferred procedure. For tumors involving the lower portion of the rectum, abdominoperineal resection (APR) or LAR are the options of treatment, depending on sphincter involvement. The main surgical objective is to achieve a R0 resection with an appropriated total mesorrectal excision, greater number of lymph nodes and negative distal and radial margins. These surgical parameters have been used as quality indicators and have prognostic implications in terms of overall and disease-free survival. Total mesorectal excision with preservation of hypogastric nerves has shown a reduction in rates of sexual and bladder dysfunction as well as lower local recurrence. At specialized centers such procedures are performed by minimal invasive surgery; however the number of meta-analysis is scarce.

    OBJECTIVE The objectives of this study were to: (1) assess differences in goal attainment of self-described goals after treatment of symptomatic pelvic organ prolapse (POP) for women who chose surgery compared to women who chose pessary; and (2) compare patient global improvement between groups. STUDY DESIGN Women who had symptomatic stage ≥ II prolapse presenting for care of POP to the urogynecology clinic at the University of New Mexico were recruited. Patients listed up to 3 goals they had for their treatment. In addition, they completed the short forms of the Pelvic Floor Distress Inventory (PFDI-20), the POP/Urinary Incontinence Sexual Questionnaire, and the Body Image Scale. Goals listed by patients were then categorized into 10 categories. Each of the listed goals was categorized based on a consensus of 5 providers. At 3 months’ follow-up patients listed if they had met their self-described goals on a scale of 0–10 and also answered the Patient Global Improvement Index (PGI-I). RESULTS There were no significant differences between the 2 groups’ baseline characteristics. Surgery patients ranked their goal attainment higher than pessary patients for all the 3 goals listed. Similarly, PGI-I scores were also higher in the surgical (2.4 ±1.1) than the pessary (1.93 ± 0.8) treatment groups (P < .04). Patients in the surgery group also had better symptom improvement as measured by the PFDI-20 (P < .02). CONCLUSION Patients who chose surgery had better global improvement and met their goals better compared to patients who chose pessary. PMID:23770473

    The tumoricidal and apoptosis-inducing activities of 5-fluorouracil (5-FU) have been demonstrated in experimental and clinical investigations. Clinically, the 5-FU suppository form has been widely adopted for its advantages of less systemic toxicity, higher local tissue concentrations, and reduced first-pass effect. In this study, we investigated the feasibility of rectal administration of 5-FU suppository based on poloxamer 188 (P188) and propylene glycol (PG) and its anticancer effect on the murine experimental cancer models. The rectal suppository was made with 70% P188 and 30% PG, which was a solid phase at room temperature and instantly melted at physiological temperature. The treatment with the 5-FU suppository was more effective than the oral route in decreasing the volume of rectal cancer in mice. In addition, the survival rate of the mice with rectal cancer was higher in the group treated with the 5-FU suppository than in the group treated with 5-FU orally. Furthermore, in mice skin cancers induced by inoculation of murine CT-26 colon carcinoma cells, the anticancer effect of 5-FU was significantly enhanced by the rectal administration of the suppository than by oral treatment. Taken together, the results suggest that a poloxamer gel system with 5-FU/P188/PG is an effective rectal dosage form for the treatment of both rectal and non-rectal cancers.

Quality reporting is critical for accurate effective communication of the information among multiple disciplines, for which a systematic structured approach is beneficial. Existing guides on reporting of rectal MRI are divergent on some issues, largely reflecting the differences in overall management of rectal cancer patients between the United States and Europe. The Korean Society of Abdominal Radiology (KSAR) study group for rectal cancer has developed an expert consensus recommendation regarding essential items for structured reporting of rectal cancer MRI using a modified Delphi method. This recommendation aims at presenting an up-to-date, evidence-based, practical, structured reporting template that can be readily adopted in daily clinical practice. In addition, a thorough explanation of the clinical and scientific rationale underlying the reporting items and their formats is provided. This KSAR recommendation may serve as a useful tool to help achieve more standardized optimal care for rectal cancer patients using rectal MRI.

    Background: The aim of this study is to compare very elderly female patients with a younger control group after prolapse surgery with regard to co-morbidity and complications. Method: In a case-control design, the consecutive data of patients after prolapse surgery at the age of over 80 years and those of a control group were analysed by means of the Clavien-Dindo (CD) classification of surgical complications, the Charlson Comorbidity Index and the Cumulative Illness Rating Scale Geriatrics (CIRS-G). Statistics: Studentʼs t, Fisherʼs exact and Mann-Whitney U tests. Results: The analysis comprised n = 57 vs. n = 60 operations. In the very elderly patients there was often a grade IV prolapse (p < 0.001), apical fixations were more frequent (p < 0.001), but the operating times were not different. In the very elderly patients 21 % CD II+III complications were observed, in the control group 6.6 % (p = 0.031). No CD IV and V complications occurred in either group, the duration of inpatient stay amounted to 5 (± 1) vs. 4.1 (± 0.8; p < 0.001) days, the very elderly patients needed an inpatient follow-up more frequently (p < 0.001). The co-morbidities of the very elderly patients differed from those of the control group in number (median 2.0 vs. 1.5; p < 0.001), in CIRS-G (4.1 ± 2.2 vs. 2.4 ± 1.7; p < 0.01) and in Charlson Index (1.6 ± 1.6 vs. 0.5 ± 0.7; p < 0.001). Conclusions: A prolapse in very elderly women can be safely managed by surgery. In no case did the complications require intensive care treatment nor were they life-threatening, but they did lead to a longer duration of hospital stay and more frequently to further treatment geriatric or inpatient internal medicine facilities.

    A wide and redundant prolapse of the posterior mitral leaflet in active infective endocarditis cannot be easily repaired. A sliding plasty can be attempted, but the range of annular plication is often too large. Chordal replacement is another option, but is prone to long-term degeneration because the redundant leaflet still exists. Here, we describe a simple resection technique that utilizes only two small triangular resections. The resections are sutured with no need to shorten the annulus. The leaflet tissue between the two triangular resections must be preserved to make an appropriately shaped posterior leaflet. PMID:23223672

    Pelvic organ prolapse is a common disease in elderly patients. The most important symptom is vaginal bulge (bulge sensation or the sensation of something coming down through the vaginal introitus). This symptom is not different than in the general population. Diagnosis can be confirmed using just vaginal examinations to identify the presence of protrusion beyond the hymen, and is not different than in the general population. Different treatment options are available, including observation, nonsurgical, and surgical techniques. Pessaries and colpocleisis are the treatment options used more often in elderly patients than in the general population.

    A group of 40 patients with symptoms of prolapsed lumbar disk, seven of which were recurrent after surgery, was studied by computed tomography. In all cases, the diagnosis was confirmed by myelography and posterior surgery. Computed tomography was performed after the disappearance of myelographic contrast medium. Positive herniated disk was shown by computed tomography in 88%. In postoperative cases, computed tomography after intravenous contrast enhancement favored the recognition of postoperative scar, rather than recurrent herniation. Computed tomography also facilitated the diagnosis of spondylotic lesions, which may accompany herniated disks. Computed tomography should reduce the need for myelography, which is reserved for cases with doubtful computed tomographic findings.

    Laparoscopic rectal surgery is feasible, oncologically safe, and offers better short-term outcomes than traditional open procedures in terms of pain control, recovery of bowel function, length of hospital stay, and time until return to working activity. Nevertheless, laparoscopic techniques are not widely used in rectal surgery, mainly because they require a prolonged and demanding learning curve that is available only in high-volume and rectal cancer surgery centres experienced in minimally invasive surgery. Robotic surgery is a new technology that enables the surgeon to perform minimally invasive operations with better vision and more intuitive and precise control of the operating instruments, promising to overcome some of the technical difficulties associated with standard laparoscopy. The aim of this review is to summarise the current data on clinical and oncological outcomes of minimally invasive surgery in rectal cancer, focusing on robotic surgery, and providing original data from the authors’ centre.

    Purpose: To predict the grade and incidence of late clinical rectal toxicity through short-term (1 year) mucosal alterations. Methods and Materials: Patients with prostate adenocarcinoma treated with curative or adjuvant radiotherapy underwent proctoscopy a year after the course of radiotherapy. Mucosal changes were classified by the Vienna Rectoscopy Score (VRS). Late toxicity data were analyzed according to the Kaplan-Meier method. Comparison between prognosis groups was performed by log-rank analysis. Results: After a median follow-up time of 45 months (range, 18-99), the 3-year incidence of grade {>=}2 rectal late toxicity according to the criteria of the European Organization for Research and Treatment of Cancer and the Radiation Therapy Oncology Group was 24%, with all patients (24/24; 100%) experiencing rectal bleeding. The occurrence of grade {>=}2 clinical rectal late toxicity was higher in patients with grade {>=}2 (32% vs. 15 %, p = 0.02) or grade {>=}3 VRS telangiectasia (47% vs. 17%, p {<=} 0.01) and an overall VRS score of {>=}2 (31% vs. 16 %, p = 0.04) or {>=}3 (48% vs. 17%, p = 0.01) at the 1-year proctoscopy. Conclusions: Early proctoscopy (1 year) predicts late rectal bleeding and therefore can be used as a surrogate endpoint for late rectal toxicity in studies aimed at reducing this frequent complication.

    Purpose: In radiotherapy for prostate cancer, the rectum is the major dose-limiting structure. Physically separating the rectum from the prostate (e.g., by injecting a spacer) can reduce the rectal radiation dose. Despite pilot clinical studies, no careful analysis has been done of the risks, benefits, and dosimetric effects of this practice. Methods and Materials: Using cadaveric specimens, 20 mL of a hydrogel was injected between the prostate and rectum using a transperineal approach. Imaging was performed before and after spacer placement, and the cadavers were subsequently dissected. Ten intensity-modulated radiotherapy plans were generated (five before and five after separation), allowing for characterization of the rectal dose reduction. To quantify the amount of prostate-rectum separation needed for effective rectal dose reduction, simulations were performed using nine clinically generated intensity-modulated radiotherapy plans. Results: In the cadaveric studies, an average of 12.5 mm of prostate-rectum separation was generated with the 20-mL hydrogel injections (the seminal vesicles were also separated from the rectum). The average rectal volume receiving 70 Gy decreased from 19.9% to 4.5% (p < .05). In the simulation studies, a prostate-rectum separation of 10 mm was sufficient to reduce the mean rectal volume receiving 70 Gy by 83.1% (p <.05). No additional reduction in the average rectal volume receiving 70 Gy was noted after 15 mm of separation. In addition, spacer placement allowed for increased planning target volume margins without exceeding the rectal dose tolerance. Conclusion: Prostate-rectum spacers can allow for reduced rectal toxicity rates, treatment intensification, and/or reduced dependence on complex planning and treatment delivery techniques.

    OBJECTIVE: To compare the safety and efficacy of abdominal sacral colpopexy and sacrospinous ligament suspension with the use of vaginal mesh for apical prolapse. METHOD: This retrospective study was conducted from 2005 to 2012 and included 89 women with apical prolapse who underwent surgery. Assessments included pre- and postoperative Pelvic Organ Prolapse Quantification (POP-Q) stage. Rates of objective cure and immediate/late complications were compared. RESULTS: In total, 41 of the 89 women underwent sacrospinous ligament suspension, and 48 of the women underwent abdominal sacral colpopexy. A total of 40.4% of the women had vault prolapse (p=0.9361). Most of them had no complications (93.2%) (p=0.9418). Approximately 30% of the women had late complications; local pain was the main symptom and was found only in women who underwent the abdominal procedure (25.6%) (p=0.001). Only the women who were submitted to the vaginal procedure had mesh exposure (18.4%). The objective success rate and the rate of anterior vaginal prolapse (p=0.2970) were similar for both techniques. CONCLUSION: Sacrospinous ligament suspension was as effective and had a similar objective success rate as abdominal sacral colpopexy for the treatment of apical prolapse. Sacrospinous ligament suspension performed with the use of vaginal mesh in the anterior compartment was effective in preventing anterior vaginal prolapse after surgery. PMID:27652828

    Both expert surgeons agree with the following: (1) Surgical mesh, whether placed laparoscopically or transvaginally, is indicated for pelvic floor reconstruction in cases involving recurrent advanced pelvic organ prolapse. (2) Procedural expertise and experience gained from performing a high volume of cases is fundamentally necessary. Knowledge of outcomes and complications from an individual surgeon's audit of cases is also needed when discussing the risks and benefits of procedures and alternatives. Yet controversy still exists on how best to teach new surgical techniques and optimal ways to efficiently track outcomes, including subjective and objective cure of prolapse as well as perioperative complications. A mesh registry will be useful in providing data needed for surgeons. Cost factors are also a consideration since laparoscopic and especially robotic surgical mesh procedures are generally more costly than transvaginal mesh kits when operative time, extra instrumentation and length of stay are included. Long-term outcomes, particularly for transvaginal mesh procedures, are lacking. In conclusion, all surgery poses risks; however, patients should be made aware of the pros and cons of various routes of surgery as well as the potential risks and benefits of using mesh. Surgeons should provide patients with honest information about their own experience implanting mesh and also their experience dealing with mesh-related complications.

    Objective The aim of this study was to assess anatomical and functional outcomes 2 years after prolapse repair using vaginal mesh repair system. Methods Women enrolled in a 12-month observational study of outcomes after transvaginal mesh-augmented prolapse repair were invited to participate in an extended follow-up. Subjects completed questionnaires assessing pelvic symptoms, quality of life, global satisfaction, and a pelvic examination for anatomical support and mesh complications. Results Of 118 eligible women, 85 enrolled, 82 provided subjective data at 24 months, and pelvic examination/Pelvic Organ Prolapse Quantification data are available from 79 women. Total, anterior, and posterior Prolift kits were used in 47 (55%), 25 (29%), and 13 (15%), respectively. At baseline, most of the women had stage III prolapse (75%), with the anterior compartment constituting the leading edge in 71% of subjects. At 24 months, Pelvic Organ Prolapse Quantification measures were significantly improved from baseline in all compartments, with 51 (65%) stage 0/I, 25 (31%) stage II, 3 (4%) and stage III (P < 0.001), as were quality of life scores (P < 0.001), with the exception of sexual function. Symptomatic prolapse was reported by 7 (8.5%) women, of which 4 demonstrated prolapse in the nonoperated compartment. Three subjects (4%) reported persistent pelvic pain. The 2-year mesh exposure incidence was at least 13% (11/85). The proportion reporting dyspareunia was 28.9% (13/45) and was unchanged from baseline. The median global satisfaction was 9.3 (range 2.0–10.0). Conclusions Anatomical support, symptom relief, and satisfaction are high 24 months after mesh-augmented vaginal prolapse repair, although mesh exposure and new onset prolapse of the nonoperated compartment are not uncommon.

  13. Transpedicular surgery for dorsolumbar junction disc prolapse: anatomic and biomechanical considerations of a minimally invasive approach.

    The dorsal spine is the least affected region of the spine for intervertebral disc prolapse. The majority of cases of thoracic disc prolapse affect the lower dorsal spine, probably due to the increased mobility of that region. The dorsolumbar junction (DLJ) comprises D10 to L1 together with the intervening discs. Over a period of nine years, we have operated on thirty-two DLJ disc prolapses using a transpedicular approach in thirty patients. There were eight cases of D10/D11 disc prolapse, ten of D11/D12, and twelve of D12/L1 prolapse. Two patients had more than 1 level involvement. Back ache was the predominant symptom in patients with DLJ disc prolapse, seen in 92 % of cases. Presentation was in the form of conus/cauda equina syndrome with D11, D12 and L1 radiculopathy. All the patients were evaluated by MRI. Disc prolapse was eccentric in 10 and diffuse central in 22 levels. There was a distinct neurological improvement in all patients after surgery, pain relief being the most prominent feature. The dorsolumbar region differs from the dorsal spine in terms of mobility, anatomic and biomechanical features. It is a transition zone between the relatively fixed dorsal spine and the mobile lumbar region. These differences account for the higher incidence of disc prolapse in the region as compared to the dorsal spine cranial to D10. The transpedicular approach appears to be most suitable for discectomy for DLJ disc prolapse. The approach is minimally invasive considering the size of the incision, minimal bone removal and avoidance of vital structures. Postoperative pain is minimal and ambulation can be begun within 24 hours of surgery.

This is the first report about carcinoid tumors in monozygotic twins. Both twins developed a similar number of rectal carcinoids with a similar distribution. Investigation of their genetic background may provide information about the origin of these tumors.

    Stomal prolapse is one of the common complications in transverse colostomy and can be managed conservatively in most cases; however, laparotomy and reconstruction of the stoma may sometimes be required, especially in case of irreducible colostomy prolapse. We have reported a simple local repair with reconstruction of the loop colostomy. We herein report a new more simple technique to avoid laparotomy and allow excision of the irreducible colostomy prolapse and complete closure of the distal limb of loop colostomy when no decompression is required in the distal limb of the stoma. In this procedure, the number of stapler and the time with blood loss for the operation can be saved.

    Depending on its location or stage, rectal cancer may differ significantly. Before any treatment decision a careful work up is mandatory relying mainly on endoscopy and imaging (MRI). Surgery according to the TME principle is the cornerstone of treatment. Most of the time surgery is associated with external beam radiotherapy often combined with concurrent chemotherapy (capecitabine) according to the neoadjuvant regimen CAP 50 (5 weeks long). It is sometimes possible to escalate safely the dose of irradiation using contact X-ray brachytherapy 50 Kv or Iridium 192 interstitial brachytherapy. Adjuvant chemotherapy may be given in case of pejorative pathological findings but its benefit is not yet proven in contrast with colon cancer. Local recurrences are becoming unusual as is permanent APE surgery with permanent stoma. To reduce the risk of distant metastasis clinical trials are testing first line chemotherapy in T3-4 lesions. For early stage (T2-"small" T3) clinical trials try to achieve organ preservation. Intensification of CAP 50 either with more chemotherapy or radiation dose escalation using contact X-ray aim at achieving a clinical complete response followed by local excision or close surveillance.

  19. Current Developments and Perspectives on the Diagnosis and Treatment of Urinary Incontinence and Genital Prolapse in Women

    As a key area of gynaecology, urogynaecology has undergone impressive changes in the past few years. Together with the high prevalence of functional pelvic floor disorders, modern anaesthesia procedures and the introduction of new, innovative minimally invasive operation techniques have led to a dramatic increase in the number of operations for incontinence and prolapses. The increasingly subtle diagnostic options, such as, e. g., 2D and 3D sonography of the pelvic floor provide unambiguous findings and facilitate decision making. Tension-free vaginal slings in retro-pubic, trans-obturator or single-incision techniques show a high success rate with few complications and have almost completely replaced the more invasive abdominal surgical techniques for the operative management of stress incontinence. Especially for recurrent prolapse the use of alloplastic nets leads to a markedly improved anatomic and functional outcome. In spite of the euphoria about modern operation techniques and novel net materials, in-depth knowledge of pelvic floor anatomy, sufficient surgical experience and unequivocal guideline-conform indications are mandatory for satisfactory treatment outcomes. The afflicted women must be informed in detail about alternative procedures and more emphasis should be placed on conservative therapy. Novel surgical techniques should be monitored by registers or clinical trials. The professional society is called upon to improve the training curricula for pelvic floor surgery. PMID:25308980

    It is difficult to make a choice among the many surgical procedures designed for the correction of stress urinary incontinence by the vaginal route because their results have not been correctly compared. The Bologna (B) operation uses two flaps from the anterior vaginal wall that are anchored to the abdominal wall; the Ingelman-Sundberg (IS) operation is a suburethral sling made from two transplants from the pubococcygeus muscle. A prospective randomized study has been carried out in order to compare these two procedures. A selection of cases has been based upon the presence of genuine or potential stress incontinence, genital prolapse and available tissues (anterior vaginal wall excess and palpable pubococcygeus muscles) for both procedures. No significant difference was noted for clinical results (91.7% and 93.7% of patients cured by the B and IS operations, respectively) or for transmission rate gain at 3 months and 1 year. Maximum urethral closing pressure was maintained in both treatment arms. No significant postoperative complication or persistent dysuria occurred. The Bologna procedure is best indicated in case of frank anterior vaginal excess, and the Ingelman-Sundberg procedure when strong anterior parts of pubococcygeus muscles are available. Both are excellent in the cure of stress incontinence associated with genital prolapse.

    Maraviroc (MVC) is a potent CCR5 coreceptor antagonist that is in clinical testing for daily oral pre-exposure prophylaxis (PrEP) for HIV prevention. We used a macaque model consisting of weekly SHIV162p3 exposures to evaluate the efficacy of oral MVC in preventing rectal SHIV transmission. MVC dosing was informed by the pharmacokinetic profile seen in blood and rectal tissues and consisted of a human-equivalent dose given 24 h before virus exposure, followed by a booster postexposure dose. In rectal secretions, MVC peaked at 24 h (10,242 ng/ml) with concentrations at 48 h that were about 40 times those required to block SHIV infection of peripheral blood mononuclear cells (PBMCs) in vitro. Median MVC concentrations in rectal tissues at 24 h (1,404 ng/g) were 30 and 10 times those achieved in vaginal or lymphoid tissues, respectively. MVC significantly reduced macrophage inflammatory protein 1β-induced CCR5 internalization in rectal mononuclear cells, an indication of efficient binding to CCR5 in rectal lymphocytes. The half-life of CCR5-bound MVC in PBMCs was 2.6 days. Despite this favorable profile, 5/6 treated macaques were infected during five rectal SHIV exposures as were 3/4 controls. MVC treatment was associated with a significant increase in the percentage of CD3(+)/CCR5(+) cells in blood. We show that high and durable MVC concentrations in rectal tissues are not sufficient to prevent SHIV infection in macaques. The increases in CD3(+)/CCR5(+) cells seen during MVC treatment point to unique immunological effects of CCR5 inhibition by MVC. The implications of these immunological effects on PrEP with MVC require further evaluation.

    The aim of the study was to assess sexual function in women before and after surgery with transvaginal mesh for pelvic organ prolapse. Women were invited to complete a sexual function questionnaire including the Lemack and the Pelvic Organ Prolapse Urinary Incontinence Sexual Questionnaires (PISQ-12) before undergoing surgery and 1 year after surgery. Eighty-three complete pre and postoperative questionnaires were analyzed. Mean age was 65.1 years. Forty-six were sexually inactive and 37 were sexually active women. Two sexually active women completed the preoperative PISQ-12 questionnaire retrospectively after surgery. There were no significant differences after surgery in the answers to the Lemack questionnaire and PISQ-12 scores. These results suggest that nonabsorbable transvaginal mesh repair of genital prolapse does not impair sexual function 1 year after surgery. Nevertheless, patients should not necessarily expect a significant improvement in sexual function outcome following transvaginal mesh repair for genital prolapse.

    The aim of this retrospective study was to evaluate the outcome of a tissue-selecting therapy stapler (TST) for prolapsing hemorrhoids in HIV-infected patients. Sixty-two patients with stage III-IV hemorrhoidal prolapse were treated with TST by a single surgeon between June and November 2014. The TST group comprised 32 patients (4 females), and the TST + HIV group comprised 30 HIV-infected patients (3 females). Age, gender, and preoperative examination as well as intraoperative and postoperative features were assessed. There was no marked difference in hemorrhoidal prolapse between the TST and HIV + TST groups, except for patient satisfaction at 12 months. TST is an effective and safe technique for treatment of prolapsing hemorrhoids in HIV-infected patients. PMID:28356909

    Pelvic organ prolapse is a common condition affecting a large number of women. Incidence increases after the menopause. Age, parity and obesity are the most consistently reported risk factors. Many women can be asymptomatic of prolapse but common symptoms include a sensation of a bulge or fullness in the vagina or urinary, bowel or sexual dysfunction. Management depends upon symptoms and the type and grade of the prolapse as well as any associated medical co-morbidities. Management options include expectant, conservative or surgical approaches. Up to 10% of women having a surgical procedure for prolapse will require a second procedure. It is, therefore, important to consider lifestyle modifications such as weight loss and conservative measures including pelvic floor muscle training, topical estrogens and pessaries as initial management options.

    There are two conventional treatments for clinically resectable rectal cancer. The first is surgery, and, if the tumor is T3 and/or N1-2, this is followed by postoperative combined-modality therapy. The second, for patients with ultrasound T3 or clinical T4 disease, is preoperative combined-modality therapy followed by surgery and postoperative chemotherapy. In this review, the results of these approaches as well as novel combined-modality approaches using oxaliplatin-based regimens will be presented.

    2015-01-01

    BACKGROUND: Transanal endoscopic microsurgery is a minimally invasive technique that allows full-thickness resection and suture closure of the defect for large rectal adenomas, selected low-risk rectal cancers, or small cancers in patients who have a high risk for major surgery. Our aim, in the given prospective study was to report our initial clinical experience with TAMIS, and to evaluate its effects on postoperative anorectal functions. MATERIALS AND METHODS: In 10 patients treated with TAMIS for benign and malignant rectal tumors, preoperative and postoperative anorectal function was evaluated with anorectal manometry and Cleveland Clinic Incontinence Score. RESULTS: The mean distance of the tumors from the anal verge was 5.6 cm, and mean tumor diameter was 2.6 cm. All resection margins were tumor free. There was no difference in preoperative and 3-week postoperative anorectalmanometry findings; only mean minimum rectal sensory volume was lower at 3 weeks after surgery. The Cleveland Clinic Incontinence Score was normal in all patients except one which resolved by 6 weeks after surgery.The mean postoperative follow-up was 28 weeks without any recurrences. CONCLUSION: Transanal minimally invasive surgery is a safe and effective procedure for treatment of rectal tumors and can be performed without impairing anorectal functions. PMID:26622116

    2017-01-01

    Purpose This study aimed to investigate the surgical outcomes and safety of robotic sacrocolpopexy (RSC) in patients with uterine/vaginal vault prolapse. Methods Between January 2009 and June 2015, 16 women with apical prolapse underwent RSC. Pelvic organ prolapse quantification (POP-Q) examination was performed, and treatment success was defined as the presence of grade 0 or I apical prolapse upon POP-Q examination at the final follow-up. Pelvic floor distress inventory-short form 20 (PFDI-SF 20) was administered at every follow-up. A treatment satisfaction questionnaire was administered by telephone to evaluate patient satisfaction with the operation. Results Median age was 65 years (interquartile range [IQR], 56–68 years), and follow-up duration was 25.3 months (IQR, 5.4–34.0 months). Thirteen women (81.3%) had ≥grade III apical prolapse. Operation time was 251 minutes (IQR, 236–288 minutes), and blood loss was 75 mL (IQR, 50–150 mL). Median hospital stay was 4 days (IQR, 3–5 days). At the final follow-up, treatment success was reported in all patients, who presented grade 0 (n=8, 57.1%) and grade I (n=6, 42.9%) apical prolapse. Dramatic improvements in PFDI-SF 20 scores were noted after RSC (from 39 to 4; P=0.001). Most patients (12 of 13) were satisfied with RSC. An intraoperative complication (sacral venous plexus injury) was reported in 1 patient, and there was no conversion to open surgery. Mesh erosion was not reported. Conclusions RSC is an efficient and safe surgical option for apical prolapse repair. Most patients were satisfied with RSC. Thus, RSC might be one of the best treatment options for apical prolapse in women. PMID:28361513

    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

    Mitral valve prolapse (MVP) is a common cardiac valve disease that affects nearly 1 in 40 individuals. It can manifest as mitral regurgitation and is the leading indication for mitral valve surgery. Despite a clear heritable component, the genetic aetiology leading to non-syndromic MVP has remained elusive. Four affected individuals from a large multigenerational family segregating non-syndromic MVP underwent capture sequencing of the linked interval on chromosome 11. We report a missense mutation in the DCHS1 gene, the human homologue of the Drosophila cell polarity gene dachsous (ds), that segregates with MVP in the family. Morpholino knockdown of the zebrafish homologue dachsous1b resulted in a cardiac atrioventricular canal defect that could be rescued by wild-type human DCHS1, but not by DCHS1 messenger RNA with the familial mutation.

    SUMMARY Mitral valve prolapse (MVP) is a common cardiac valve disease that affects nearly 1 in 40 individuals1–3. It can manifest as mitral regurgitation and is the leading indication for mitral valve surgery4,5. Despite a clear heritable component, the genetic etiology leading to non-syndromic MVP has remained elusive. Four affected individuals from a large multigenerational family segregating non-syndromic MVP underwent capture sequencing of the linked interval on chromosome 11. We report a missense mutation in the DCHS1 gene, the human homologue of the Drosophila cell polarity gene dachsous (ds) that segregates with MVP in the family. Morpholino knockdown of the zebrafish homolog dachsous1b resulted in a cardiac atrioventricular canal defect that could be rescued by wild-type human DCHS1, but not by DCHS1 mRNA with the familial mutation. Further genetic studies identified two additional families in which a second deleterious DCHS1 mutation segregates with MVP. Both DCHS1 mutations reduce protein stability as demonstrated in zebrafish, cultured cells, and, notably, in mitral valve interstitial cells (MVICs) obtained during mitral valve repair surgery of a proband. Dchs1+/− mice had prolapse of thickened mitral leaflets, which could be traced back to developmental errors in valve morphogenesis. DCHS1 deficiency in MVP patient MVICs as well as in Dchs1+/− mouse MVICs result in altered migration and cellular patterning, supporting these processes as etiological underpinnings for the disease. Understanding the role of DCHS1 in mitral valve development and MVP pathogenesis holds potential for therapeutic insights for this very common disease. PMID:26258302

    Pelvic organ prolapse, a herniation of pelvic organs through the vagina, is a common condition in older women. Pelvic organ prolapse distorts vaginal anatomy making pelvic examination difficult. A clinician must accurately identify anatomic landmarks both in women presenting with symptoms of prolapse and in women noted to have coincidental prolapse during routine gynecologic examination. We present a systematic approach to the female pelvic examination including anatomic landmarks of the external genitalia, vagina, and uterus in women with normal support as well as changes that occur with pelvic organ prolapse. Knowledge and awareness of normal anatomic landmarks will improve a clinician's ability to identify defects in pelvic support and allow for better diagnosis and treatment of pelvic organ prolapse.

    This article describes a 1.5-year-old female, Greek Hound dog, weighing 16 kg, presented with a type III vaginal prolapse which occurred during the last third of pregnancy. Trans-abdominal ultrasonography revealed four live foetuses in the uterine horns. The animal was hospitalized and 4 days later gave birth without any interference. Three days later, resection of the prolapsed tissue was performed and the bitch recovered completely. Recurrence of a type I vaginal prolapse was observed 4 months later, during subsequent oestrus. This case is unusual because, although vaginal fold prolapse is mainly seen during proestrus/oestrus or during parturition, it was first noticed 47 days after mating and 13 days before parturition. Furthermore, even though the prolapse of vaginal fold was of type III and of considerable size, parturition proceeded normally. Finally, even though resection of the prolapsed tissue was performed 3 days after parturition, recurrence of vaginal fold oedema (type I) was observed in the subsequent oestrus.

    Since 2004, the standard of care for patients with cT3 and/or N+ rectal cancer has been preoperative chemoradiation followed by surgery and postoperative adjuvant chemotherapy. A number of advances have occurred and are defining the future of rectal cancer therapy. Among these are short course radiation, the impact of postoperative adjuvant chemotherapy, selective radiation and selective surgery, and new chemoradiation regimens with novel agents. This review will examine these developments and assess their impact on the future therapy of rectal cancer.

    This study was conducted to evaluate the safety of laparoscopic radical resection for rectal cancer. A total of 64 cases of rectal cancer patients undergoing radical surgery between January, 1998 and March, 2010 were collected. The patients were divided into the laparoscopic rectal surgery group (LS group, n=31) and the open surgery group (OS group, n=33). Operation time, postoperative recovery, complications and tumor-free survival rate were compared between the two groups. The inclusion criteria were as follows: Standard Karnofsky score >70 prior to surgery, definitive pathological diagnosis and complete clinical data. The exclusion criteria were concomitant tumors affecting survival. With the Dixon operation, the LS group had a longer operation time compared with the OS group (271.2±56.2 vs. 216.0±62.7 min, respectively; P=0.036), and an earlier time of oral intake (3.0±0.9 vs. 4.7±1.0 days, respectively; P=0.000). There were no significant differences between the LS and OS groups in terms of intraoperative blood loss, number of lymph nodes retrieved, duration of postoperative hyperthermia and hospitalization time (P>0.05). With the Miles operation, there were no obvious differences between the LS and OS groups regarding operation time, intraoperative blood loss, number of lymph nodes retrieved, time of oral intake, duration of postoperative hyperthermia and hospitalization time (P>0.05). Furthermore, there were no significant differences between the LS and OS groups with the Dixon or Miles operation in terms of 3-year tumor-free survival rate (P>0.05). Thus, laparoscopic surgery appears to be a safe and feasible option for the treatment of rectal cancer. PMID:28357087

    Solitary rectal ulcer causing lower gastrointestinal bleeding is extremely rare in children. Rare presentation, non-specific symptoms, insufficient experience, and characteristics mimicking other rectal diseases may cause misdiagnosis or delay of diagnosis in some pediatric patients. Here, we report a 10-year-old boy with solitary rectal ulcer diagnosed two years after onset of the symptoms who responded well to the conservative therapy, including high-fiber diet, laxatives, defecation training, and sucralfate enema.

    It has been reported that, by the age of 80, the risk of women to undergo surgery for the treatment of pelvic organ prolapse (POP) exceeds 10%, a percentage expected to increase with the rise in life expectancy. The vaginal approach for POP reconstructive operations is associated with fewer complications and results in a shorter rehabilitation period than the abdominal route, whereas hysterectomy is widely performed concomitantly whenever the uterus is significantly prolapsed. However, there is no clear evidence supporting the role of hysterectomy in improving surgery outcome. We present our experience with a new minimally invasive procedure--the posterior intravaginal slingplasty (PIVS) for correction of advanced uterine prolapse--at the same time, comparing additive vaginal hysterectomy to uterine preservation, to evaluate the therapeutic significance of hysterectomy when vaginal apical prolapse is reconstructed with PIVS. Seventy-nine women presenting with moderate to severe uterine prolapse were enrolled into the current PIVS study. Vaginal hysterectomy was concomitantly performed upon patient's request (44 patients), whereas those wishing to preserve their uterus underwent reconstructive surgery only (35 patients). No intraoperative or postoperative major complications were recorded during an average follow-up of 29.8 months: One patient (1.3%) presented with surgical failure, whereas 71 (89.9%) of the operated patients reported satisfaction with the therapeutic results. Bladder overactivity symptoms declined from three thirds of the patients preoperatively to below 10% postoperatively. Ten (12.7%) patients had vaginal tape protrusion; all underwent segmental tape resection at the out-patient clinic. Because the PIVS procedure does not require either laparotomy or deep transvaginal dissection, as previously required for operative intervention, the hospitalization period was relatively short: 4.2 days for the hysterectomy group and 1.5 for the non

    To quantify OCT images of rectal tissue for clinic diagnosis, the scattering coefficient of the tissue is extracted by curve fitting the OCT signals to a confocal single model. A total of 1000 measurements (half and half of normal and malignant tissues) were obtained from 16 recta. The normal rectal tissue has a larger scattering coefficient ranging from 1.09 to 5.41 mm-1 with a mean value of 2.29 mm-1 (std:±0.32), while the malignant group shows lower scattering property and the values ranging from 0.25 to 2.69 mm-1 with a mean value of 1.41 mm-1 (std:±0.18). The peri-cancer of recta has also been investigated to distinguish the difference between normal and malignant rectal tissue. The results demonstrate that the quantitative analysis of the rectal tissue can be used as a promising diagnostic criterion of early rectal cancer, which has great value for clinical medical applications.

    New Zealand has one of the highest incidences of rectal cancer in the world, and its optimal management requires a multidisciplinary approach. A National Rectal Cancer Summit was convened in August 2013 to discuss management of rectal cancer in the New Zealand context, to highlight controversies and discuss domestic priorities for the future. This paper summarises the priorities for treatment, research and policy for rectal cancer services in New Zealand identified as part of the Summit in August. The following priorities were identified: - Access to high-quality information for service planning, review of outcomes, identification of inequities and gaps in provision, and quality improvement; - Engagement with the entire sector, including private providers; - Focus on equity; - Emerging technologies; - Harmonisation of best practice; - Importance of multidisciplinary team meetings. In conclusion, improvements in outcomes for patients with rectal cancer in New Zealand will require significant engagement between policy makers, providers, researchers, and patients in order to ensure equitable access to high quality treatment, and strategic incorporation of emerging technologies into clinical practice. A robust clinical information framework is required in order to facilitate monitoring of quality improvements and to ensure that equitable care is delivered.

    2015-01-01

    Rectal varices are portosystemic collaterals that form as a complication of portal hypertension, their prevalence has been reported as high as 94% in patients with extrahepatic portal vein obstruction. The diagnosis is typically based on lower endoscopy (colonoscopy or sigmoidoscopy). However, endoscopic ultrasonography has been shown to be superior to endoscopy in diagnosing rectal varices. Color Doppler ultrasonography is a better method because it allows the calculation of the velocity of blood flow in the varices and can be used to predict the bleeding risk in the varices. Although rare, bleeding from rectal varices can be life threatening. The management of patients with rectal variceal bleeding is not well established. It is important to ensure hemodynamic stability with blood transfusion and to correct any coagulopathy prior to treating the bleeding varices. Endoscopic injection sclerotherapy has been reported to be more effective in the management of active bleeding from rectal varices with less rebleeding rate as compared to endoscopic band ligation. Transjugular intrahepatic portsystemic shunt alone or in combination with embolization is another method used successfully in control of bleeding. Balloon-occluded retrograde transvenous obliteration is an emerging procedure for management of gastric varices that has also been successfully used to treat bleeding rectal varices. Surgical procedures including suture ligation and porto-caval shunts are considered when other methods have failed. PMID:26730278

    Between 5% and 10% of patients with rectal cancer present with locally advanced rectal cancer (LARC), and 10% of rectal cancers recur after surgery, of which half are limited to locoregional disease only (locally recurrent rectal cancer). Exenterative surgery offers the best long-term outcomes for patients with LARC and locally recurrent rectal cancer so long as a complete (R0) resection is achieved. Accurate preoperative multimodal staging is crucial in assessing the potential operability of advanced rectal tumors, and resectability may be enhanced with neoadjuvant therapies. Unfortunately, surgical options are limited when the tumor involves the lateral pelvic sidewall or high sacrum due to the technical challenges of achieving histological clearance, and must be balanced against the high morbidity associated with resection of the bony pelvis and significant lymphovascular structures. This group of patients is usually treated palliatively and subsequently survival is poor, which has led surgeons to seek innovative new solutions, as well as revisit previously discarded radical approaches. A small number of centers are pioneering new techniques for resection of beyond-total mesorectal excision tumors, including en bloc resections of the sciatic notch and composite resections of the first two sacral vertebrae. Despite limited experience, these new techniques offer the potential for radical treatment of previously inoperable tumors. This narrative review sets out the challenges facing the management of LARCs and discusses evolving management options. PMID:27785074

    Myxomatous mitral valve prolapse (MMVP) and fibroelastic deficiency (FED) are two common variants of degenerative mitral valve disease (DMVD), which is a leading cause of mitral regurgitation worldwide. While pathohistological studies have revealed differences in extracellular matrix content in MMVP and FED, the molecular mechanisms underlying these two disease entities remain to be elucidated. By using surgically removed valvular specimens from MMVP and FED patients that were categorized on the basis of echocardiographic, clinical and operative findings, a cluster of microRNAs that expressed differentially were identified. The expressions of has-miR-500, -3174, -17, -1193, -646, -1273e, -4298, -203, -505, and -939 showed significant differences between MMVP and FED after applying Bonferroni correction (p < 0.002174). The possible involvement of microRNAs in the pathogenesis of DMVD were further suggested by the presences of in silico predicted target sites on a number of genes reported to be involved in extracellular matrix homeostasis and marker genes for cellular composition of mitral valves, including decorin (DCN), aggrecan (ACAN), fibromodulin (FMOD), α actin 2 (ACTA2), extracellular matrix protein 2 (ECM2), desmin (DES), endothelial cell specific molecule 1 (ESM1), and platelet/ endothelial cell adhesion molecule 1 (PECAM1), as well as inverse correlations of selected microRNA and mRNA expression in MMVP and FED groups. Our results provide evidence that distinct molecular mechanisms underlie MMVP and FED. Moreover, the microRNAs identified may be targets for the future development of diagnostic biomarkers and therapeutics.

    Mitral valve prolapse (MVP) results from the systolic movement of a portion(s) or segment(s) of the mitral valve leaflet(s) into the left atrium during left ventricular (LV) systole. It should be emphasised that MVP alone, as defined by imaging techniques, may comprise a non-specific finding because it also depends on the LV volume, myocardial contractility and other LV hemodynamics. Thus, a floppy mitral valve (FMV) should be the basis for the diagnosis of MVP. Two types of symptoms may be defined in these patients. In one group, symptoms are directly related to progressive mitral regurgitation and its complications. In the other group, symptoms cannot be explained only by the degree of mitral regurgitation alone; neuroendocrine dysfunction has been implicated for the explanation of symptoms in this group of patients that today is referred as the FMV/MVP syndrome. When significant mitral regurgitation is present in a patient with FMV/MVP, surgical intervention is recommended. In patients with a prohibitive risk for surgery, transcatheter mitral valve repair using a mitraclip device may be considered. Furthermore, transcatheter mitral valve replacement may represent an option in the near future as clinical trials are underway. In this brief review, the current concepts related to FMV/MVP and FMV/MVP syndrome will be discussed.

    AIM To analyze the outcomes of transanal endoscopic microsurgery (TEM) in the treatment of rare rectal condition like mesenchymal tumors, condylomas, endometriosis and melanoma. METHODS We retrospectively reviewed a twenty-three years database. Fifty-two patients were enrolled in this study. The lesions were considered suitable for TEM if they were within 20 cm from the anus. All of them underwent an accurate preoperative workup consisting in clinical examination, total colonoscopy with biopsies, endoscopic ultrasonography, and pelvic computerized tomography or pelvic magnetic resonance imaging. Operative time, intraoperative complications, rate of conversion, tumor size, postoperative morbidity, mortality, the length of hospital stay, local and distant recurrence were analyzed. RESULTS Among the 1328 patients treated by TEM in our department, the 52 patients with rectal abnormalities other than adenoma or adenocarcinoma represented 4.4%. There were 30 males (57.7%) and 22 females (42.3%). Mean age was 55 years (median = 60, range = 24-78). This series included 14 (26.9%) gastrointestinal stromal tumors, 21 neuroendocrine tumors (40.4%), 1 ganglioneuroma (1.9%), 2 solitary ulcers in the rectum (3.8%), 6 cases of rectal endometriosis (11.5%), 6 cases of rectal condylomatosis (11.5%) and 2 rectal melanomas (3.8%). Mean lesion diameter was 2.7 cm (median: 4, range: 0.4-8). Mean distance from the anal verge was 9.5 cm (median: 10, range: 4-15). One patient operated for rectal melanoma developed distant metastases and died two years after the operation. We experienced 2 local recurrences (3.8%) with an overall survival equal to 97.6% (95%CI: 95%-99%) at the end of follow-up and a disease free survival of 98% (95%CI: 96%-99%). CONCLUSION We could conclude that TEM is an important therapeutical option for rectal rare conditions. PMID:27668073

    The authors studied the prevalence of mitral valve prolapse (MVP) in the group of 656 children and adolescents (329 males and 327 females), who were a representative sample (obtained with the Monte Carlo method of statistical trials) of all newborns in the city of Maribor, Republic of Slovenia, in the period of 18 years (1976-1992). The results were considered positive in children and adolescents who in addition to possible history (chest pain, palpitations, dizziness, loss of consciousness, headaches, perspiration), probable auscultatory finding (mezzosystolic click and late systolic murmur), and suspected phonocardiographic and ECG findings, also had a positive M-mode echocardiographic finding. The criteria for MVP on M-mode echocardiography were taken from the literature: descending of mitral cusp, either anterior or posterior, of at least 3 mm below the line connecting points C and D. Children and adolescents were divided into six age groups (infants, toddlers, preschool children, early school age, children in puberty, adolescents). Assuming MVP as a cause of cardiac arrhythmias, beside standard ECG we also performed holter ECG monitoring in 61 children and adolescents (29 with MVP, 32 without MVP). The results were tested with standard statistical tools (chi 2-test, Student t-test, 2 x 2 Fisher chi 2-test). MVP was found in 71 patients (10.8%, 32 males and 39 females). As regards age and sex we found lower prevalence of MVP in male children (9.7%) compared to female children (11.9%). The highest prevalence was found in early school age, more so in females (14.2 vs 13.7). The differences were not statistically significant (p > 0.05). In both sexes most frequent was endosystolic prolapse (males 59.3%, females 51.3%). Most commonly both cusps are involved in the prolapse (males 78.1%, females 66.7%). Most frequently measured descending of the cusps was 3-4.5 mm (males 56.2%, females 48.7%). Negative auscultatory finding (silent MVP) was detected in 47.8% of the

    There is growing evidence the microbiota of the large bowel may influence the risk of developing colorectal cancer as well as other diseases including type-1 diabetes, inflammatory bowel diseases and irritable bowel syndrome. Current sampling methods to obtain microbial specimens, such as feces and mucosal biopsies, are inconvenient and unappealing to patients. Obtaining samples through rectal swabs could prove to be a quicker and relatively easier method, but it is unclear if swabs are an adequate substitute. We compared bacterial diversity and composition from rectal swabs and rectal mucosal biopsies in order to examine the viability of rectal swabs as an alternative to biopsies. Paired rectal swabs and mucosal biopsy samples were collected in un-prepped participants (n = 11) and microbial diversity was characterized by Terminal Restriction Fragment Length polymorphism (T-RFLP) analysis and quantitative polymerase chain reaction (qPCR) of the 16S rRNA gene. Microbial community composition from swab samples was different from rectal mucosal biopsies (p = 0.001). Overall the bacterial diversity was higher in swab samples than in biopsies as assessed by diversity indexes such as: richness (p = 0.01), evenness (p = 0.06) and Shannon's diversity (p = 0.04). Analysis of specific bacterial groups by qPCR showed higher copy number of Lactobacillus (p < 0.0001) and Eubacteria (p = 0.0003) in swab samples compared with biopsies. Our findings suggest that rectal swabs and rectal mucosal samples provide different views of the microbiota in the large intestine.

    Purpose: To convey the occurrence of isolated cases of severe rectal toxicity at the highest dose level tested in 5-fraction stereotactic body radiation therapy (SBRT) for localized prostate cancer; and to rationally test potential causal mechanisms to guide future studies and experiments to aid in mitigating or altogether avoiding such severe bowel injury. Methods and Materials: Clinical and treatment planning data were analyzed from 91 patients enrolled from 2006 to 2011 on a dose-escalation (45, 47.5, and 50 Gy in 5 fractions) phase 1/2 clinical study of SBRT for localized prostate cancer. Results: At the highest dose level, 6.6% of patients treated (6 of 91) developed high-grade rectal toxicity, 5 of whom required colostomy. Grade 3+ delayed rectal toxicity was strongly correlated with volume of rectal wall receiving 50 Gy >3 cm{sup 3} (P<.0001), and treatment of >35% circumference of rectal wall to 39 Gy (P=.003). Grade 2+ acute rectal toxicity was significantly correlated with treatment of >50% circumference of rectal wall to 24 Gy (P=.010). Conclusion: Caution is advised when considering high-dose SBRT for treatment of tumors near bowel structures, including prostate cancer. Threshold dose constraints developed from physiologic principles are defined, and if respected can minimize risk of severe rectal toxicity.

    In patients with genital prolapse involving several compartments simultaneously, radiologic investigation can be used to complement the clinical assessment. Contrast medium in the urinary bladder enables visualization of the bladder base at cystodefecoperitoneography (CDP). The aim of the present study was to evaluate the correlation between clinical examination using the Pelvic Organ Prolapse Quantification system (POP-Q) and CDP. Thirty-three women underwent clinical assessment and CDP. Statistical analysis using Pearson's correlation coefficient ( r) demonstrated a wide variability between the current definition of cystocele at CDP and POP-Q ( r=0.67). An attempt to provide an alternative definition of cystocele at CDP had a similar outcome ( r=0.63). The present study demonstrates a moderate correlation between clinical and radiologic findings in patients with anterior vaginal wall prolapse. It does not support the use of bladder contrast at radiologic investigation in the routine preoperative assessment of patients with genital prolapse.

  19. Intracellular pH in Gastric and Rectal Tissue Post Cardiac Arrest

    We directly measured pHi using the pH sensitive dye, neutral red. We defined pHi for rectal and gastric tissue in whole tissue and by layer under control and arrest conditions. Fifteen minutes of arrest was not sufficient time to alter the pHi at the rectal or gastric site. On initial inspection, the stomach may be more sensitive to ischemic changes than the rectum. Understanding the mechanism by which PCO2 generation is used to track clinical changes is vital to the early detection of tissue dysoxia in order to effectively treat and manage critically ill patients.

  20. Technical feasibility of laparoscopic extended surgery beyond total mesorectal excision for primary or recurrent rectal cancer.

    Relatively little is known about the oncologic safety of laparoscopic surgery for advanced rectal cancer. Recently, large randomized clinical trials showed that laparoscopic surgery was not inferior to open surgery, as evidenced by survival and local control rates. However, patients with T4 tumors were excluded from these trials. Technological advances in the instrumentation and techniques used by laparoscopic surgery have increased the use of laparoscopic surgery for advanced rectal cancer. High-definition, illuminated, and magnified images obtained by laparoscopy may enable more precise laparoscopic surgery than open techniques, even during extended surgery for T4 or locally recurrent rectal cancer. To date, the quality of evidence regarding the usefulness of laparoscopy for extended surgery beyond total mesorectal excision has been low because most studies have been uncontrolled series, with small sample sizes, and long-term data are lacking. Nevertheless, laparoscopic extended surgery for rectal cancer, when performed by specialized laparoscopic colorectal surgeons, has been reported safe in selected patients, with significant advantages, including a clear visual field and less blood loss. This review summarizes current knowledge on laparoscopic extended surgery beyond total mesorectal excision for primary or locally recurrent rectal cancer.

    Abstract Rationale: Hemolymphangioma is a rare developmental error of combined blood and lymphatic vasculature. To the best of our knowledge, there is only one case of rectal hemolymphangioma reported in Pubmed. Our case probably is the first reported rectal hemolymphangioma with computed tomography (CT) evaluation. Patient concerns and diagnosis: A 57-year-old male was presented to our hospital with 55 years of long history of episodic rectal bleeding. Past medical history showed numerous hospital visits for similar illness. Multiple diagnoses were made and different treatment modalities were applied for his benefit, but none of them relieved the symptoms permanently. He was then referred to our hospital. On admission, he was presented with intermediate rectal bleeding of fresh blood. CT examination showed isodense homogenous rectal wall thickening with heterogeneous enhancement on contrast examination. Multiple calcifications were seen in and around the lesion. Interventions and outcomes: He underwent open abdominal surgery with total surgical excision of the lesion. Post-surgical histopathological examination of excised specimen showed submucosal multiple thin-walled vessel of varying size, some consistent with blood vessel and other with lymph vessel, thus diagnosis of hemolymphangioma was made. Follow-up for 6 months showed no recurrence. Lessions: Hemolymphangioma is a benign developmental lesion. Radiological findings can be challenging and range from benign cystic lesion to aggressive lesion mimicking malignancy. Therefore, combined clinical history, radiological findings, and continuous follow-up can help make proper diagnosis and provide prompt and accurate treatment. PMID:28272235

    AIM To evaluate the importance of endoscopic ultrasonography (EUS) for small (≤ 10 mm) rectal neuroendocrine tumor (NET) treatment. METHODS Patients in whom rectal NETs were diagnosed by endoscopic resection (ER) at the Pusan National University Yangsan Hospital between 2008 and 2014 were included in this study. A total of 120 small rectal NETs in 118 patients were included in this study. Histologic features and clinical outcomes were analyzed, and the findings of endoscopy, EUS and histology were compared. RESULTS The size measured by endoscopy was not significantly different from that measured by EUS and histology (r = 0.914 and r = 0.727 respectively). Accuracy for the depth of invasion was 92.5% with EUS. No patients showed invasion of the muscularis propria or metastasis to the regional lymph nodes. All rectal NETs were classified as grade 1 and demonstrated an L-cell phenotype. Mean follow-up duration was 407.54 ± 374.16 d. No patients had local or distant metastasis during the follow-up periods. CONCLUSION EUS is not essential for ER in the patient with small rectal NETs because of the prominent morphology and benign behavior. PMID:28373770

    Introduction Cervical spondylotic myelo-radiculopathy is a form of spinal cord dysfunction syndrome and usually accompanies age related degeneration of the spine. Aim To determine the functional outcome of anterior cervical discectomy with fusion and plating in single level degenerative cervical disc prolapse. Materials and Methods A total of 20 patients diagnosed with degenerative single level cervical disc prolapse who presented to the Department of Orthopaedic Surgery, Justice KS Hegde Charitable Hospital, Mangalore from the period of November 2012 to May 2014 were enrolled in the study. Complete clinical and radiological evaluation of the patients was done. A trial of conservative management was tried in all these patients for a period of two months. They were taken up for surgery only when conservative management had failed. Scoring of neck function before the surgery was done as per the Modified Japanese Orthopaedic Association (MJOA) score. All patients underwent anterior cervical discectomy and fusion (ACDF) with tricortical iliac crest bone grafting. Fixation was performed with titanium locking cervical plates. All patients were reviewed at 6 weeks and 6 months postoperatively. Assessment of neck function was done as per the MJOA scoring during all the reviews. Radiographic assessment was also done during all the reviews. The complications noted were documented. The statistical analysis was done using percentages; the arithmetic mean was calculated using SPSS software (version 16.0). Results Amongst the 20 patients included in the study, 1 patient died postoperatively due to oesophageal rupture. of the remaining 19 patients reviewed and followed up, all of them had improvement of symptoms and were reported to be in the ‘mild category’ as per the MJOA score. One patient developed dysphonia, in the immediate postoperative period due to recurrent laryngeal nerve palsy which recovered in a period of three months postoperative. Conclusion Single level

    Standard chemoradiotherapy (CRT) for local advanced rectal cancer (LARC) rarely induce rectal perforation. Here we report a rare case of rectal perforation in a patient with LARC in the midst of preoperative CRT. A 56-year-old male was conveyed to our hospital exhibiting general malaise. Colonoscopy and imaging tests resulted in a clinical diagnosis of LARC with direct invasion to adjacent organs and regional lymphadenopathy. Preoperative 5-fluorouracil-based CRT was started. At 25 d after the start of CRT, the patient developed a typical fever. Computed tomography revealed rectal perforation, and he underwent emergency sigmoid colostomy. At 12 d after the surgery, the remaining CRT was completed according to the original plan. The histopathological findings after radical operation revealed a wide field of tumor necrosis and fibrosis without lymph node metastasis. We share this case as important evidence for the treatment of LARC perforation in the midst of preoperative CRT. PMID:28138443

  6. MALT lymphoma of the rectum, presenting with rectal prolapsus: a case report

    PubMed Central

    2010-01-01

    Up to now, there have been only a few reported cases of Mucosa-associated lymphoid tissue (MALT) lymphomas arising in the rectum. Its clinical presentation is indistinguishable from that of rectal carcinoma but the treatment is apparently different. Symptoms of primary lymphomas involving the rectum include; anorexia, weight loss, change in bowel habits, obstruction, and bleeding. These symptoms are not disease specific and can be seen in many other gastrointestinal disorders. Patients with polypoid masses may present with obstruction symptoms. In this rare case, a female patient admitted to the emergency service with prolapsus of a rectal mass. The optimal treatment of rectal MALT lymphoma is not well defined yet, given the rarity of the disease. Surgical resection of the localized lesion and following adjuvant chemotherapy has proved to be an effective treatment option. However, a close and long-lasting follow-up is important. PMID:20180989

    Anterior resection with total mesorectal excision is the standard method of rectal cancer resection. However, this procedure remains technically difficult in mid and low rectal cancer. A robotic transanal proctectomy with total mesorectal excision and laparoscopic assistance is reported in a 57 year old male with BMI 32 kg/m2 and rectal adenocarcinoma T2N1M0 at 5 cm from the dentate line. Operating time was 420 min. Postoperative hospital stay was 6 days and no complications were observed. Pathological report showed a 33 cm specimen with ypT2N0 adenocarcinoma at 2 cm from the distal margin, complete TME and non affected circumferential resection margin. Robotic technology might reduce some technical difficulties associated with TEM/TEO or SILS platforms in transanal total mesorectal excision. Further clinical trials will be necessary to assess this technique.

    Nonsyndromic mitral valve prolapse (MVP) is a common degenerative cardiac valvulopathy of unknown etiology that predisposes to mitral regurgitation, heart failure and sudden death. Previous family and pathophysiological studies suggest a complex pattern of inheritance. We performed a meta-analysis of 2 genome-wide association studies in 1,412 MVP cases and 2,439 controls. We identified 6 loci, which we replicated in 1,422 cases and 6,779 controls, and provide functional evidence for candidate genes. We highlight LMCD1 (LIM and cysteine-rich domains 1), which encodes a transcription factor and for which morpholino knockdown of the ortholog in zebrafish resulted in atrioventricular valve regurgitation. A similar zebrafish phenotype was obtained with knockdown of the ortholog of TNS1, which encodes tensin 1, a focal adhesion protein involved in cytoskeleton organization. We also showed expression of tensin 1 during valve morphogenesis and describe enlarged posterior mitral leaflets in Tns1(-/-) mice. This study identifies the first risk loci for MVP and suggests new mechanisms involved in mitral valve regurgitation, the most common indication for mitral valve repair.

  9. Vaginal Approaches Using Synthetic Mesh to Treat Pelvic Organ Prolapse

    Pelvic organ prolapse (POP) is a very common condition in elderly women. In women with POP, a sacrocolpopexy or a vaginal hysterectomy with anterior and posterior colporrhaphy has long been considered as the gold standard of treatment. However, in recent decades, the tendency to use a vaginal approach with mesh for POP surgery has been increasing. A vaginal approach using mesh has many advantages, such as its being less invasive than an abdominal approach and easier to do than a laparoscopic approach and its having a lower recurrence rate than a traditional approach. However, the advantages of a vaginal approach with mesh for POP surgery must be weighed against the disadvantages. Specific complications that have been reported when using mesh in POP procedures are mesh erosion, dyspareunia, hematomas, urinary incontinence and so on, and evidence supporting the use of transvaginal surgery with mesh is still lacking. Hence, surgeons should understand the details of the surgical pelvic anatomy, the various surgical techniques for POP surgery, including using mesh, and the possible side effects of using mesh.

    Non-syndromic mitral valve prolapse (MVP) is a common degenerative cardiac valvulopathy of unknown aetiology that predisposes to mitral regurgitation, heart failure and sudden death1. Previous family and pathophysiological studies suggest a complex pattern of inheritance2–5. We performed a meta-analysis of two genome-wide association studies in 1,442 cases and 2,439 controls. We identified and replicated in 1,422 cases and 6,779 controls six loci and provide functional evidence for candidate genes. We highlight LMCD1 encoding a transcription factor6, for which morpholino knockdown in zebrafish results in atrioventricular (AV) valve regurgitation. A similar zebrafish phenotype was obtained for tensin1 (TNS1), a focal adhesion protein involved in cytoskeleton organization. We also show the expression of tensin1 during valve morphogenesis and describe enlarged posterior mitral leaflets in Tns1−/− mice. This study identifies the first risk loci for MVP and suggests new mechanisms involved in mitral valve regurgitation, the most common indication for mitral valve repair7. PMID:26301497

    To describe trends in the utilization of surgical procedures for pelvic organ prolapse among women in Olmsted County, MN, we retrospectively identified all county residents undergoing pelvic organ prolapse repair from January 1, 1965 through December 31, 2002. From 1965 to 2002, 3,813 women had pelvic organ prolapse surgeries: 3,126 had hysterectomy combined with pelvic floor repair (PFR) procedures and 687 had PFR alone. The age-adjusted utilization of hysterectomy plus PFR and of PFR alone decreased by 62% (P < 0.001) and 32% (P = 0.02), respectively. In both groups, utilization decreased in all age groups over time except in women aged 80 years and older undergoing hysterectomy plus PFR and women aged 70 years and older undergoing PFR only. The most common indication for PFR was uterovaginal prolapse. Among women in the community, the rate of utilization and age distribution of pelvic organ prolapse surgery changed substantially between 1965 and 2002.

    Two asymptomatic elderly women who underwent cataract extraction 7 or more years previously and with intraocular lens placement presented with a linear bead-like white multinodular mass in the inferior angle simulating iris metastasis versus large inflammatory precipitates. There was no iris infiltration. In the first case, the posterior lens capsule was intact and there was no evidence of gelatinous vitreous in the anterior chamber, whereas in the second case, the capsule was open and there was gelatinous vitreous prolapse. In both cases, there was asteroid hyalosis in the vitreous. Both patients were diagnosed with prolapsed vitreous asteroid hyalosis into the anterior chamber and managed with observation. Vitreous asteroid hyalosis can prolapse into the anterior chamber of pseudophakic elderly patients with or without capsular opening and can simulate an intraocular tumor.

    Chest pain is rare and usually benign in pediatrics. Cardiac etiology is even rarer. However, it is a symptom associated with ischemic heart disease and it imposes great social alarm, even in health care workers. Therefore, it is necessary to know the most common causes of this symptom in children, as well as serious diseases that can cause it, which require prompt medical attention. We report a case of chest pain associated with ischemic electrocardiographic changes in a patient with mitral valve prolapse and MASS phenotype (mitral valve prolapse, aortic root enlargement, and skeletal and skin alterations), we review the mitral valve prolapse and stress the importance of knowing it in the pediatric setting.

    Purpose. To evaluate the treatment tolerance and clinical outcomes in patients aged 70 and older with locally advanced rectal carcinoma treated with multimodality approach. Methods and Materials. We retrospectively analysed 20 consecutive elderly patients, with histologically proven rectal adenocarcinoma, staged T3-4, and/or node-positive tumour, who received chemoradiotherapy and proceeded to surgical approach. Performance status score and adult comorbidity evaluation-27 score were calculated, and their influence on treatment tolerance and clinical outcomes was analysed. Results. All patients completed programmed chemoradiotherapy treatment. Gastrointestinal toxicity was the most common acute side effects: proctitis in 70% of patients and diarrhoea in 55%, classified as Grade 3 in 3 patients only. Radiation dermatitis was reported in 7 patients (35%) and it was graded G3 in one patient. There was no haematological toxicity. Eighteen patients out of 20 underwent surgery. Sphincter preservation was assured in 13 patients. Comorbidity index was related to higher severe acute toxicity (P = 0.015) but no influenced treatment outcomes. Conclusion. Treatment tolerance with combined modality is good in elderly patients. Due to age, no dose reduction for radiation therapy and chemotherapy should be considered. PMID:24392453

    In 2014, there were an estimated 136800 new cases of colorectal cancer, making it the most common gastrointestinal malignancy. It is the second leading cause of cancer death in both men and women in the United States and over one-third of newly diagnosed patients have stage III (node-positive) disease. For stage II and III colorectal cancer patients, the mainstay of curative therapy is neoadjuvant therapy, followed by radical surgical resection of the rectum. However, the consequences of a proctectomy, either by low anterior resection or abdominoperineal resection, can lead to very extensive comorbidities, such as the need for a permanent colostomy, fecal incontinence, sexual and urinary dysfunction, and even mortality. Recently, trends of complete regression of the rectal cancer after neoadjuvant chemoradiation therapy have been confirmed by clinical and radiographic evaluation-this is known as complete clinical response (cCR). The "watch and wait" approach was first proposed by Dr. Angelita Habr-Gama in Brazil in 2009. Those patients with cCR are followed with close surveillance physical examinations, endoscopy, and imaging. Here, we review management of rectal cancer, the development of the "watch and wait" approach and its outcomes.

    2014-01-01

    The concepts for management of rectal cancer have changed drastically over the past few years. Through national bowel cancer screening programmes in the Western countries and the increasing use of endoscopic procedures as diagnostic tool, there is increase in detection of rectal cancer in early stages. There is increase in ageing population worldwide but more so in Western countries. In addition, there is realisation of harm from extirpative surgical procedures which are directed towards managing advanced rectal cancer in the past. Increase in cost of health care burden has also led the investigators to seek alternative treatment options which are effective, safe and cost effective. There are several modern radiation techniques which fits this bill and we need to be aware of newer novel radiation techniques to fulfil this gap. PMID:24982769

    Background Many women without preexisting stress urinary incontinence (SUI) who undergo vaginal surgery to correct pelvic organ prolapse will develop symptoms of SUI. A concomitant prophylactic anti-incontinence procedure may prevent SUI symptom development in women undergoing vaginal prolapse surgery. Purpose To present the rationale, design and methodology of a randomized controlled surgical trial (RCT), the Outcomes Following Vaginal Prolapse Repair and Mid Urethral Sling (OPUS) Trial. The primary aims of this RCT are to determine (1) whether the prevalence of post-operative urinary incontinence (UI) differs between stress continent women receiving vaginal prolapse repair with concomitant tension-free vaginal tape (TVT®; a sling procedure commonly used to treat SUI) and those with only sham incisions at 3 months post surgery (2) whether it is more cost-effective to place a TVT prophylactically than to treat the SUI symptoms postoperatively as they occur over a 12 month period after the index surgery.. The study also incorporates a patient preference trial (PPT). Methods Primary outcome, defined as signs (positive cough stress test), symptoms (per validated questionnaire) and/or need for treatment of SUI and its associated cost, at 3 and 12 months post-operatively. Secondary outcomes consist of group differences in lower urinary tract and prolapse symptoms, health related quality of life, measures of vaginal anatomy, and surgical complications. Limitations Given the invasive nature of surgical intervention trials, some individuals may be reluctant to agree with random assignment, potentially impacting result generalizability. To evaluate the magnitude and direction of non-participation bias, the PPT will enroll a sample of those who decline participation in the RCT but are otherwise eligible. Conclusion This sham-controlled RCT will provide important information for patients and surgeons regarding both the short- and long-term optimal treatment approach for

    Background and Objectives: To evaluate the efficacy of laparoscopic sacrocervicopexy for apical support in sexually active patients with pelvic organ prolapse. Methods: One-hundred thirty-five women with symptomatic prolapse of the central compartment (Pelvic Organ Prolapse Quantitative [POP-Q] stage 2) underwent laparoscopic sacrocervicopexy. The operating physicians used synthetic mesh to attach the anterior endopelvic fascia to the anterior longitudinal ligament of the sacral promontory with subtotal hysterectomy. Anterior and posterior colporrhaphy was performed when necessary. The patients returned for follow-up examinations 1 month after surgery and then over subsequent years. On follow-up a physician evaluated each patient for the recurrence of genital prolapse and for recurrent or de novo development of urinary or bowel symptoms. We define “surgical failure” as any grade of recurrent prolapse of stage II or more of the POP-Q test. Patients also gave feedback about their satisfaction with the procedure. Results: The mean follow-up period was 33 months. The success rate was 98.4% for the central compartment, 94.2% for the anterior compartment, and 99.2% for the posterior compartment. Postoperatively, the percentage of asymptomatic patients (51.6%) increased significantly (P < .01), and we observed a statistically significant reduction (P < .05) of urinary urge incontinence, recurrent cystitis, pelvic pain, dyspareunia, and discomfort. The present study showed 70.5% of patients stated they were very satisfied with the operation and 18.8% stated high satisfaction. Conclusion: Laparoscopic sacrocervicopexy is an effective option for sexually active women with pelvic organ prolapse. PMID:23925017

    Uterine prolapse is a major reproductive health issue in Nepal. There is a wide range of literature available on the causes and risk factors of uterine prolapse and on the ways to prevent and treat it. There is still a lack of published evidence on what prevention and treatment services are working well or the attitudes toward them. This paper presents the findings of a qualitative study on primary and secondary prevention of uterine prolapse in Eastern Nepal. Method The study involved eight focus group discussions with 71 women in six villages of the eastern districts of Siraha and Saptari and 14 qualitative interviews with health professionals from the local to central level. The group discussions and interviews covered the awareness levels of uterine prolapse and its prevention and treatment, as well as participants’ opinions on and experiences with the services offered. Results It was found that patriarchy, gender discrimination, and cultural traditions such as early marriage and pregnancy make it difficult for people to discontinue uterine prolapse risk behaviors. Women are aware of risk factors, prevention, and treatment, but are powerless to change their situations. Health professionals and women are fond of surgery as treatment, but opinions on the use of ring pessaries and pelvic floor muscle training are split. Conclusion The main recommendation that can be drawn from this study is that research on the effectiveness of early treatments, such as ring pessaries and exercise, should be conducted. Furthermore, the involvement of other target groups (husbands, adolescents, and mothers-in-law) needs to be increased in order to make it easier for women to adapt low-risk behaviors. Finally, uterine prolapse prevention should be better integrated in national reproductive health services. Enforcing transparency, monitoring systems, and collaborations are important factors that should be considered as well. PMID:22927768

    PubMed Central

    Glimelius, Bengt

    2013-01-01

    In rectal cancer treatment, attention has focused on the local primary tumour and the regional tumour cell deposits to diminish the risk of a loco-regional recurrence. Several large randomized trials have also shown that combinations of surgery, radiotherapy and chemotherapy have markedly reduced the risk of a loco-regional recurrence, but this has not yet had any major influence on overall survival. The best results have been achieved when the radiotherapy has been given preoperatively. Preoperative radiotherapy improves loco-regional control even when surgery has been optimized to improve lateral clearance, i.e., when a total mesorectal excision has been performed. The relative reduction is then 50%-70%. The value of radiotherapy has not been tested in combination with more extensive surgery including lateral lymph node clearance, as practised in some Asian countries. Many details about how the radiotherapy is performed are still open for discussion, and practice varies between countries. A highly fractionated radiation schedule (5 Gy × 5), proven efficacious in many trials, has gained much popularity in some countries, whereas a conventionally fractionated regimen (1.8-2.0 Gy × 25-28), often combined with chemotherapy, is used in other countries. The additional therapy adds morbidity to the morbidity that surgery causes, and should therefore be administered only when the risk of loco-regional recurrence is sufficiently high. The best integration of the weakest modality, to date the drugs (conventional cytotoxics and biologicals) is not known. A new generation of trials exploring the best sequence of treatments is required. Furthermore, there is a great need to develop predictors of response, so that treatment can be further individualized and not solely based upon clinical factors and anatomic imaging. PMID:24379566

    Legal issues related to vaginal mesh devices for prolapse and incontinence include abnormal injury and inadequate informed consent. Although vaginal mesh devices are currently cleared through the 510(k) process, new developments at the US Food and Drug Administration requiring additional postmarket studies (522 studies) for transvaginal mesh for prolapse and mini-suburethral synthetic slings have been issued to ensure product safety and effectiveness. New initiatives including unique device identification numbers and the Pelvic Floor Disorders Registry have been developed to improve surveillance throughout the total product/device life cycle.

    A 44-year-old man presented with a large and rapidly growing skin lesion approximately six months after resection of a rectal carcinoma. The lesion measured 40 cm in size, extended from the suprapubic area to the proximal half of the left groin, and showed a particular zosteriform aspect. Biopsy confirmed a metastatic skin adenocarcinoma. Cutaneous metastases from rectal cancer are very uncommon. Their gross appearance is not distinctive, although the skin tumors are usually solid, small (less than 5 cm) and painless nodules or papules. Early biopsies for suspicious skin lesions are needed in patients with a history of colorectal cancer.

    A transanal approach to rectal polyp and cancer excision is often an appropriate alternative to conventional rectal resection, and has a lower associated morbidity. There has been a steady evolution in the techniques of transanal surgery over the past 30 years. It started with traditional transanal excision and was revolutionized by introduction of transanal endoscopic microsurgery in early 1980s. Introduction of transanal minimally invasive surgery made it more accessible to surgeons around the world. Now robotic platforms are being tried in certain institutions. Concerns have been raised about recurrence rates of cancers with transanal approach and success of subsequent salvage operations. PMID:26929754

    Background— Arrhythmic mitral valve prolapse (MVP) is characterized by myxomatous leaflets and left ventricular (LV) fibrosis of papillary muscles and inferobasal wall. We searched for morphofunctional abnormalities of the mitral valve that could explain a regional mechanical myocardial stretch. Methods and Results— Thirty-six (27 female patients; median age: 44 years) arrhythmic MVP patients with LV late gadolinium enhancement on cardiac magnetic resonance and no or trivial mitral regurgitation, and 16 (6 female patients; median age: 40 years) MVP patients without LV late gadolinium enhancement were investigated by morphofunctional cardiac magnetic resonance. Mitral annulus disjunction (median: 4.8 versus 1.8 mm; P<0.001), end-systolic mitral annular diameters (median: 41.2 versus 31.5; P=0.004) and end-diastolic mitral annular diameters (median: 35.5 versus 31.5; P=0.042), prevalence of posterior systolic curling (34 [94%] versus 3 [19%]; P<0.001), and basal to mid LV wall thickness ratio >1.5 (22 [61%] versus 4 [25%]; P=0.016) were higher in MVP patients with late gadolinium enhancement than in those without. A linear correlation was found between mitral annulus disjunction and curling (R=0.85). A higher prevalence of auscultatory midsystolic click (26 [72%] versus 6 [38%]; P=0.018) was also noted. Histology of the mitral annulus showed a longer mitral annulus disjunction in 50 sudden death patients with MVP and LV fibrosis than in 20 patients without MVP (median: 3 versus 1.5 mm; P<0.001). Conclusions— Mitral annulus disjunction is a constant feature of arrhythmic MVP with LV fibrosis. The excessive mobility of the leaflets caused by posterior systolic curling accounts for a mechanical stretch of the inferobasal wall and papillary muscles, eventually leading to myocardial hypertrophy and scarring. These mitral annulus abnormalities, together with auscultatory midsystolic click, may identify MVP patients who would need arrhythmic risk stratification. PMID

    We studied whether evaluation of overall left ventricular (LV) and left atrial (LA) mechanics would be useful to detect subclinical dysfunction in patients with mitral valve prolapse (MVP), mitral regurgitation (MR), and normal LV ejection fraction (EF). Fifty consecutive patients (27 men, mean age 61 ± 19 years) with MVP, MR, and normal systolic function (LVEF ≥60%) were prospectively enrolled and compared with 40 age- and gender-matched healthy subjects (22 men, mean age: 59 ± 16 years). At baseline, 2-dimensional and color-flow Doppler transthoracic echocardiography were performed for MR quantification and analysis of left-chambers mechanics. Patients were divided into groups by severity of MR: mild (n = 14), moderate (n = 19), and severe (n = 17). Left ventricular dimensions, volume and mass, and LA area and volume indices were significantly increased in patients with moderate and severe MR compared with control subjects. Circumferential strain, basal/apical rotations, and twist were significantly enhanced in patients with moderate MR compared with controls; with the exception of basal rotation, they decreased in those with severe MR. Furthermore, LA strain and untwisting rate were progressively and significantly reduced from normal subjects to patients with severe MR. Effective regurgitant orifice area and MR vena contracta were significantly related to most systolic and diastolic function parameters and LA volume as well as LA strain and LV untwisting rate in all patients. In conclusion, cardiac mechanics indices, particularly LA deformation and LV rotational parameters, could help unmask incipient myocardial dysfunction in patients with MVP, especially in those with severe MR and yet normal LVEF.

    Purpose: To propose a random forest normal tissue complication probability (RF-NTCP) model to predict late rectal toxicity following prostate cancer radiation therapy, and to compare its performance to that of classic NTCP models. Methods and Materials: Clinical data and dose-volume histograms (DVH) were collected from 261 patients who received 3-dimensional conformal radiation therapy for prostate cancer with at least 5 years of follow-up. The series was split 1000 times into training and validation cohorts. A RF was trained to predict the risk of 5-year overall rectal toxicity and bleeding. Parameters of the Lyman-Kutcher-Burman (LKB) model were identified and a logistic regression model was fit. The performance of all the models was assessed by computing the area under the receiving operating characteristic curve (AUC). Results: The 5-year grade ≥2 overall rectal toxicity and grade ≥1 and grade ≥2 rectal bleeding rates were 16%, 25%, and 10%, respectively. Predictive capabilities were obtained using the RF-NTCP model for all 3 toxicity endpoints, including both the training and validation cohorts. The age and use of anticoagulants were found to be predictors of rectal bleeding. The AUC for RF-NTCP ranged from 0.66 to 0.76, depending on the toxicity endpoint. The AUC values for the LKB-NTCP were statistically significantly inferior, ranging from 0.62 to 0.69. Conclusions: The RF-NTCP model may be a useful new tool in predicting late rectal toxicity, including variables other than DVH, and thus appears as a strong competitor to classic NTCP models.

    Background: Neoadjuvant concurrent chemoradiotherapy (CCRT) followed by surgery is the mainstay of treatment for locally advanced rectal cancer. Several heparin-binding associated proteins have been reported to play a critical role in cancer progression. However, the clinical relevancies of such proteins and their associations with CCRT response in rectal cancer have not yet to be fully elucidated. Methods: The analysis of a public transcriptome of rectal cancer indicated that thrombospondin 2 (THBS2) is a predictive factor for CCRT response. Immunohistochemical analyses were conducted to evaluate the expression of THBS2 in pretreatment biopsy specimens from rectal cancer patients without distant metastasis. Furthermore, the relationships between THBS2 expression and various clinicopathological factors or survival were analyzed. Results: Low expression of THBS2 was significantly associated with advanced pretreatment tumor (P<0.001) and nodal status (P=0.004), post-treatment tumor (P<0.001) and nodal status (P<0.001), increased vascular invasion (P=0.003), increased perineural invasion (P=0.023) and inferior tumor regression grade (P=0.015). In univariate analysis, low THBS2 expression predicted worse outcomes for disease-free survival, local recurrence-free survival and metastasis-free survival (all P<0.001). In multivariate analysis, low expression of THBS2 still served as a negative prognostic factor for disease-free survival (Hazard ratio=3.057, P=0.002) and metastasis-free survival (Hazard ratio=3.362, P=0.012). Conclusion: Low THBS2 expression was correlated with advanced disease status and low tumor regression after preoperative CCRT and that it acted as an independent negative prognostic factor in rectal cancer. THBS2 may represent a predictive biomarker for CCRT response in rectal cancer. PMID:26807188

    There has been increasing interest in whether a watch-and-wait strategy can be pursued instead of routine surgery in selected rectal cancer patients who have a clinical complete response (cCR) after chemoradiation. The watch-and-wait approach could potentially reduce treatment-related toxicity in selected rectal cancer patients. A large study from Brazil and a prospective trial from the Netherlands appear to support this approach, although multiple other studies have raised concerns about the high rate of local recurrence with this strategy. This article reviews current evidence in support of a watch-and-wait approach to rectal cancer management, and discusses the challenges and limitations of this approach. Among these are the facts that current methods of assessing tumor response have limited accuracy, and that a cCR does not necessarily imply pathologic complete response. Careful patient selection and systematic methods of response assessment and follow-up will be critical to the success of nonoperative approaches. Based on the available evidence, ideally a watch-and-wait approach for patients with rectal cancer should be pursued within the context of a prospective clinical trial.

    Background Tissue Doppler imaging (TDI) is a new echocardiographic imaging technique that is believed to be superior to older conventional techniques in assessing abnormalities of cardiac function in many conditions affecting the heart. There are very limited data regarding the role of TDI in evaluating patients with mitral valve prolapse (MVP). Current study evaluates diastolic function in patients with MVP by this method. Methods From November 2009 to April 2011, one hundred and ten adults matched for age and sex and without structural heart disease were studied in two groups, with and without MVP, at Madani Heart Center, Tabriz, Iran. TDI was performed at the basal-lateral wall and S, E, E’, A, and A’ velocities, as well as the E/A and E’/A’ ratios were measured. Mitral annular systolic velocity and early diastolic (E’) velocities were measured lateral corner of mitral valve in apical 4-chamber view. Results Patients with MVP had higher left atrium volume (42.31 ± 10.47 vs. 35.19 ± 9.15 cm3; P < 0.001) and deceleration time (186.70 ± 26.00 vs. 176.89 ± 20.36 ms; P = 0.03). Diastolic dysfunction, although seemed more prevalent in MVP group (14.54%) than normal subjects (5.45%), the difference was not statistically significant between groups (P = 0.11). Conclusion Left atrial volume and deceleration time of mitral valve inflow was significantly higher in MVP which could be indicative of early stages of diastolic dysfunction in patients with MVP. However, larger follow-up studies are required to evaluate clinical significance of our findings in these patients.

    Synthetic or biological materials can be used for the surgical repair of pelvic organ prolapse (POP) or stress urinary incontinence (SUI). While non-degradable synthetic mesh has a low failure rate, it is prone to complications such as infection and erosion, particularly in the urological/gynecological setting when subject to chronic influences of gravity and intermittent, repetitive strain. Biological materials have lower complication rates, although allografts and xenografts have a high risk of failure and the theoretical risk of infection. Autografts are used successfully for the treatment of SUI and are not associated with erosion; however, can lead to morbidity at the donor site. Tissue engineering has thus become the focus of interest in recent years as researchers seek an ideal tissue remodeling material for urogynecological repair. Herein, we review the directions of current and future research in this exciting field. Electrospun poly-L-lactic acid (PLA) and porcine small intestine submucosa (SIS) are two promising scaffold material candidates. Adipose-derived stem cells (ADSCs) appear to be a suitable cell type for scaffold seeding, and cells grown on scaffolds when subjected to repetitive biaxial strain show more appropriate biomechanical properties for clinical implantation. After implantation, an appropriate level of acute inflammation is important to precipitate moderate fibrosis and encourage tissue strength. New research directions include the use of bioactive materials containing compounds that may help facilitate integration of the new tissue. More research with longer follow-up is needed to ascertain the most successful and safe methods and materials for pelvic organ repair and SUI treatment.

    Pelvic organ prolapse (POP) is a common multifactorial condition. Matrix metalloproteinases (MMPs) are enzymes capable of breaking down various connective tissue elements. Single-nucleotide polymorphisms (SNPs) in regulatory areas of MMP-encoding genes can alter their transcription rate, and therefore the possible effect on pelvic floor supporting structures. The insertion of an adenine (A) base in the promoter of the MMP-3 gene at position −1612/−1617 produces a sequence of six adenines (6A), whereas the other allele has five (5A). The aim of the present study was to investigate the possible association of MMP-3 gene promoter SNPs with the risk of POP. The patient group comprised 80 women with clinically significant POP [Stage II, III or IV; POP quantification (POP-Q) system]. The control group consisted of 80 females without any or important pelvic floor support defects (Stages 0 or I; POP-Q system). All the participants underwent the same preoperative evaluation. SNP detection was determined with whole blood sample DNA analysis by quantitative polymerase chain reaction (PCR) in LightCycler® PCR platforms, using the technique of sequence-specific hybridization probe-binding assays and melting temperature curve analysis. The results showed there was no statistically significant difference between 5A/5A, 5A/6A and 6A/6A MMP-3 gene promoter variants in the two study groups (P=0.4758). Therefore, MMP-3 gene promoter SNPs alone is insufficient to increase the genetic susceptibility to POP development. PMID:27588175

    Rectal bezoars commonly occur due to seeds, especially in children living in countries south of the Mediterranean and in the Middle-East. Dried seeds are considered a delicacy and consumed widely. Inadequate chewing or hastily eating without removing the hull may lead to their impaction as bezoars, which may require manual removal under general anaesthesia.

    Objective To compare the effects of pelvic floor muscle training and watchful waiting on pelvic floor symptoms in a primary care population of women aged 55 years and over with symptomatic mild pelvic organ prolapse. Design Randomised controlled trial. Setting Dutch primary care. Participants Women aged 55 years or over with symptomatic mild prolapse (leading edge above the hymen) were identified by screening. Exclusion criteria were current prolapse treatment or treatment in the previous year, malignancy of pelvic organs, current treatment for another gynaecological disorder, severe/terminal illness, impaired mobility, cognitive impairment, and insufficient command of the Dutch language. Interventions Pelvic floor muscle training versus watchful waiting. Main outcome measures The primary outcome was change in bladder, bowel, and pelvic floor symptoms measured with the Pelvic Floor Distress Inventory-20 (PFDI-20), three months after the start of treatment. Secondary outcomes were changes in condition specific and general quality of life, sexual function, degree of prolapse, pelvic floor muscle function, and patients’ perceived change in symptoms. Results Of the 287 women who were randomised to pelvic floor muscle training (n=145) or watchful waiting (n=142), 250 (87%) completed follow-up. Participants in the intervention group improved by (on average) 9.1 (95% confidence interval 2.8 to 15.4) points more on the PFDI-20 than did participants in the watchful waiting group (P=0.005). Of women in the pelvic floor muscle training group, 57% (82/145) reported an improvement in overall symptoms from the start of the study compared with 13% (18/142) in the watchful waiting group (P<0.001). Other secondary outcomes showed no significant difference between the groups. Conclusions Although pelvic floor muscle training led to a significantly greater improvement in PFDI-20 score, the difference between the groups was below the presumed level of clinical relevance (15 points

    The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice.A 47-year-old woman was referred for management of a newly diagnosed rectal cancer. She presented with a 2-month history of rectal bleeding and change in bowel habits. She underwent a colonoscopy that demonstrated a 5-cm fungating, friable, and partially obstructing mass in the distal rectum, approximately 5 cm from the anal verge. The tumor was palpable on digital rectal examination on the anterior wall of rectum. The biopsy demonstrated a moderately differentiated invasive adenocarcinoma, microsatellite stable. A staging work-up, including a computed tomography scan of the chest, abdomen, and pelvis, demonstrated rectal wall thickening in the midrectum and small lymph nodes in the left perirectal fat. There was a nonspecific 3-mm right lower lobe pulmonary nodule. Rectal magnetic resonance imaging demonstrated a 3-cm mass arising from mid-distal rectum with minimal extension beyond muscularis propria into the mesorectal fat, but without invasion of mesorectal fascia (Fig 1). There were at least three small mesorectal lymph nodes present; the largest rounded node measured up to 5 mm, and no additional pelvic lymphadenopathy was identified. Her carcinoembryonic antigen was 1.1, and all other laboratory studies were within normal limits. She was seen in the Colorectal Multidisciplinary Conference for a discussion of her treatment options.

    Rectal cancer, defined as a cancerous lesion of the colon distal to the rectosigmoid junction, is the fourth most common cancer cause of death globally. There were 474 patients with rectal cancer who underwent surgery between October 2007 and May 2013 enrolled in our center. Patients were respectively categorized by neoadjuvant therapy. This study aimed to explore the predictive factors that affected the Progression-free survival and overall survival of the patients with rectal cancer. Clinical characteristics of patients were compared with the groups and potential prognostic factors were analyzed by SPSS 19.0. In our study, neoadjuvant therapy increased the anus-retained rate (64.4 vs 53.4 % P = 0.016) and remission rate in the treatment group, compared to the non-treatment group (62.6 vs 34.8 %; P = 0.000). The neoadjuvant concurrent chemoradiotherapy, more operative duration, anus retained and micturition damaged are positive prognostic factors of PFS to patients. Poor differentiation, the tumor of ulcer, invasive, and pT4 stage, contributed the poor factors for PFS of patients (P < 0.05). Additionally, the patients with neoadjuvant concurrent chemoradiotherapy and adjuvant chemotherapy underwent the better prognosis of OS. Adjuvant chemotherapy cannot increase PFS of the patients who accepted neoadjuvant therapy after surgery get pCR, but can improve OS. The anus-retained and neoadjuvant radiotherapy, duration of surgery in rectal cancer have the positive correlation. Micturition damaged and neoadjuvant radiotherapy were positively correlated as well. In conclusion, adjuvant chemotherapy does not improve the PFS of patients with pCR to neoadjuvant therapy, but is good for OS. Further prospective and large population-based clinical studies are needed to establish clinical guidelines for the use of neoadjuvant therapy and adjuvant chemotherapy in patients with rectal cancer.

    Purpose The aim of this study was to evaluate the effect of surgical repair of pelvic organ prolapse on female sexual function and to assess correlations between the two using two current standardized questionnaires. Materials and Methods From October 2009 to September 2010, 143 patients with posterior compartment or combined vaginal prolapse were included. We assessed surgical outcomes according to anatomical change in the vagina and results of the Female Sexual Function Index (FSFI) and Pelvic Organ Prolapse/Urinary Incontinence Sexual Function questionnaire (PISQ-12) both pre- and postoperatively. Results Among the 143 preoperative patients, 99 and 84 patients responded to the PISQ-12 and FSFI, respectively. The mean PISQ-12 score increased after surgery (p<0.001). Specifically, postoperative scores for questions 8 and 12 were higher than their respective preoperative scores (p<0.001). Postoperatively, mean FSFI score changed only slightly (p=0.76), and only the score for the satisfaction domain was improved (p=0.023). In regards to vaginal anatomy, vaginal length was significantly greater postoperatively (6.99±0.18 vs. 7.56±1.08, p<0.001), and postoperative vaginal caliber was narrowed to a two-finger width. Conclusion In this study, surgery for pelvic organ prolapse was shown to affect female sexual function. Moreover, menopause was associated with a change in postoperative sexual function.

    The pelvic organ prolapse quantification system (POP-Q) is currently the most quantitative, site-specific system for describing pelvic organ prolapse. To ensure that anatomic outcomes can be optimally assessed, investigators in the Pelvic Floor Disorders Network evaluated the impact of specific technique variations on POP-Q measurements performed on 133 patients by 16 examiners at seven sites. Values for genital hiatus and perineal body were higher when measured with maximal strain than on resting. With the exception of TVL, internal points did not differ significantly when measured with or without a speculum. The maximum extent of prolapse was best seen with the patient standing. These results suggest that genital hiatus and perineal body should be measured at rest and during straining, as the measurements may assess different aspects of pelvic floor function, and that internal points can be measured with or without a speculum. They also emphasize the value of the standing examination to observe the maximum extent of pelvic organ prolapse.

    Laparoscopic colposacropexy has become a substitute for open surgery in the treatment of pelvic organ prolapse. In the same way, robotic assisted surgery is a new step in the evolution of the procedure. In this paper we intend to show our surgical technique and preliminary results. From November 2006 to date, 10 patients have undergone this procedure at the Hospital Clinico San Carlos. The main indication for the operation was existence of symptomatic pelvic prolapse. Both patients with or without hysterectomy have been operated, without making significant differences between them. Preoperative evaluation workout included: cystogram, urinary tract ultrasound and urodynamics in all cases; urinary tract MRI was performed only in selected cases. All patients underwent surgery under general anesthesia, with at least three robotic trocars (8 mm) and one conventional trocar for the assistant; 2 accessory trocars were necessary in some cases, mainly at the beginning of the series. Most procedures in our series were associated with a transobturator suburethral sling for the treatment of stress urinary incontinence or prevention of its appearance after prolapse repair. Our results are comparable to those reported in other larger series in terms of operative time, hospital stay and early or late complications. Pending an evaluation on the long term with larger series, we can include robot assisted colposacropexy among the therapeutic options for symptomatic pelvic floor prolapse repair.

    Purpose: To assess the impacts of patient age and comorbid illness on rectal toxicity following external beam radiation therapy (EBRT) for prostate cancer and to assess the Qualitative Analysis of Normal Tissue Effects in the Clinic (QUANTEC) normal tissue complication probability (NTCP) model in this context. Methods and Materials: Rectal toxicity was analyzed in 718 men previously treated for prostate cancer with EBRT (≥75 Gy). Comorbid illness was scored using the Charlson Comorbidity Index (CCMI), and the NTCP was evaluated with the QUANTEC model. The influence of clinical and treatment-related parameters on rectal toxicity was assessed by Kaplan-Meier and Cox proportional hazards models. Results: The cumulative incidence of rectal toxicity grade ≥2 was 9.5% and 11.6% at 3 and 5 years and 3.3% and 3.9% at 3 and 5 years for grade ≥3 toxicity, respectively. Each year of age predicted an increasing relative risk of grade ≥2 (P<.03; hazard ratio [HR], 1.04 [95% confidence interval (CI), 1.01-1.06]) and ≥3 rectal toxicity (P<.0001; HR, 1.14 [95% CI,1.07-1.22]). Increasing CCMI predicted rectal toxicity where a history of either myocardial infarction (MI) (P<.0001; HR, 5.1 [95% CI, 1.9-13.7]) or congestive heart failure (CHF) (P<.0006; HR, 5.4 [95% CI, 0.6-47.5]) predicted grade ≥3 rectal toxicity, with lesser correlation with grade ≥2 toxicity (P<.02 for MI, and P<.09 for CHF). An age comorbidity model to predict rectal toxicity was developed and confirmed in a validation cohort. The use of anticoagulants increased toxicity independent of age and comorbidity. NTCP was prognostic for grade ≥3 (P=.015) but not grade ≥2 (P=.49) toxicity. On multivariate analysis, age, MI, CHF, and an NTCP >20% all correlated with late rectal toxicity. Conclusions: Patient age and a history of MI or CHF significantly impact rectal toxicity following EBRT for the treatment of prostate cancer, even after controlling for NTCP.

    Purpose Pelvic organ prolapse (POP) is a major health issue worldwide, affecting 6-8% of women. The most affected site is the anterior vaginal wall. Multiple procedures and surgical techniques have been used, with or without the use of vaginal meshes, due to common treatment failure, reoperations, and complication rates in some studies. Methods Systematic review of the literature and meta-analysis regarding the use of vaginal mesh in anterior vaginal wall prolapse was performed. A total of 115 papers were retrieved after using the medical subject headings (MESH) terms: 'anterior pelvic organ prolapse OR cystocele AND surgery AND (mesh or colporrhaphy)' in the PubMed database. Exclusion criteria were: follow-up shorter than 1 year, use of biological or absorbable meshes, and inclusion of other vaginal wall prolapses. Studies were put in a data chart by two independent editors; results found in at least two studies were grouped for analysis. Results After the review of the titles by two independent editors, 70 studies were discarded, and after abstract assessment, 18 trials were eligible for full text screening. For final screening and meta-analysis, after applying the Jadad score (> 2), 12 studies were included. Objective cure was greater in the mesh surgery group (odds ratio [OR] = 1,28 [1,07-1,53]), which also had greater blood loss (mean deviation [MD] = 45,98 [9,72-82,25]), longer surgery time (MD = 15,08 [0,48-29,67]), but less prolapse recurrence (OR = 0,22 [01,3-0,38]). Dyspareunia, symptom resolution and reoperation rates were not statistically different between groups. Quality of life (QOL) assessment through the pelvic organ prolapse/urinary incontinence sexual questionnaire (PISQ-12), the pelvic floor distress inventory (PFDI-20), the pelvic floor impact questionnaire (PFIQ-7), and the perceived quality of life scale (PQOL) was not significantly different. Conclusions Anterior vaginal prolapse mesh surgery has greater anatomic

    Objective: To evaluate the effect of colporrhaphy on sexual problems of women with pelvic organ prolapseis. Methodology: Sixty patients with pelvic organ prolapse (cystocele - rectocele) in a quasi-experimental study before and after treatment were included. Presence of pelvic organ prolapseis was assessed by examination in the lithotomy position. Degree of prolapse was determined according to Pelvic organ Prolapse Quantification (POPQ). Their degree of prolapse was marked from 1 to 3 then was colporrhaphy performed. Follow up of patients for sexual satisfaction was performed three and six months after surgery by telephone and interviews. Data were analyzed by SPSS version 15, the McNamara test, T-test, absolute and relative frequency, mean and standard deviation. Results: In sixty (60) women who were studied the mean and standard deviation of pregnancy and delivery rate were 4.4 ±2.2 and 4±2.1 respectively. About 65% of patients were over 35 years of age, 88.3% of women had the history of vaginal delivery and 10% of them had both the history of vaginal delivery and cesarean section. Score of sexual desire abstaining from sex and orgasm due to vaginal bulge before, 3 months and 6 months after colporrhaphy was significant (p=0.0001), but of sexual arousal scores there was no differences between each other. Mean of sexual satisfaction before operation was 30.75±5.70 and three months after operation it was 33.77±4.24 and six months after operation 36.03±3.5 which according to T-Test there was significant (p=0.0001). Conclusion: Sexual desire, orgasm and sexual satisfaction increased after colporrhaphy, frequency of intercourse and sexual arousal remains unchanged. It appears that colporrhaphy reduce symptoms associated with prolapse which is leading to sexual dissatisfaction and improved sexual satisfaction. PMID:24353530

    Objective The aim of our study was to observe pelvic organ prolapse (POP) over time, treated and untreated, in a group of highly characterized women being followed subjectively and objectively over 5-7 years following continence surgery. Study design We measured baseline prolapse symptoms and anatomic prolapse in subjects enrolled in the Trial of Mid Urethral slings (TOMUS) and E-TOMUS trials, and measured these same parameters annually for five to seven years after the index surgery. Additional information about subsequent treatment for POP was also recorded. Results 597 women were randomized to one of two mid-urethral sling procedures in the TOMUS trial; concomitant vaginal procedures for POP were allowed at the surgeon’s discretion. Stage 2 POP was present at baseline in 291 of subjects (49%). Symptoms of POP were reported in 67 (25%). Of the asymptomatic women, 34/223 (15%) underwent a concomitant POP repair at the time of index sling surgery. Anatomic progression of prolapse in women with asymptomatic, unoperated stage 2 POP over the next 72 months was infrequent and occurred in only 3/189 subjects (2%); none underwent surgery for POP. Most symptomatic women [47/67 (70%)] underwent a concomitant repair for POP at the index sling surgery. Three of the 47 women who had undergone concomitant repair for symptomatic stage 2 POP underwent repeat POP surgery (2 at 36 months and 1 at 48 months.) Conclusion For patient populations similar to the TOMUS and E-TOMUS populations, surgeons may counsel women with asymptomatic stage 2 POP that their prolapse is unlikely to require surgery in the next 5–7 years.

    Objective To compare vaginal repair augmented by mesh with traditional colporrhaphy for the treatment of pelvic organ prolapse. Design Prospective randomised controlled trial. Setting Tertiary teaching hospital. Population One hundred and thirty-nine women with stage ≥2 prolapse according to the pelvic organ prolapse quantification (POP-Q) system requiring both anterior and posterior compartment repair. Methods Subjects were randomised to anterior and posterior vaginal repair with mesh augmentation (mesh group, n= 69) or traditional anterior and posterior colporrhaphy (no mesh group, n= 70). Main outcome measures The primary outcome was the absence of POP-Q stage ≥2 prolapse at 12 months. Secondary outcomes were symptoms, quality-of-life outcomes and satisfaction with surgery. Complications were also reported. Results For subjects attending the 12-month review, success in the mesh group was 81.0% (51 of 63 subjects) compared with 65.6% (40/61) in the no mesh group and was not significantly different (P-value = 0.07). A high level of satisfaction with surgery and improvements in symptoms and quality-of-life data were observed at 12 months compared to baseline in both groups, but there was no significant difference in these outcomes between the two groups. Vaginal mesh exposure occurred in four women in the mesh group (5.6%). De novo dyspareunia was reported by five of 30 (16.7%) sexually active women in the mesh group and five of 33 (15.2%) in the no mesh group at 12 months. Conclusion In this study, vaginal surgery augmented by mesh did not result in significantly less recurrent prolapse than traditional colporrhaphy 12 months following surgery. PMID:19583714

    Objective The aim of this study was to compare the curative effect between minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) and the posterior lumbar interbody fusion (PLIF) in obese patients with lumbar disk prolapse. Patients and methods In this study, 72 patients who underwent lumbar disk prolapse therapy in the Third Hospital of Hebei Medical University between March 2011 and 2015 were retrospectively analyzed and were divided into two groups, MIS-TLIF group (n=35) and PLIF group (n=37), according to different surgical procedures. Several clinical parameters were compared between these two groups. Results Compared with PLIF, MIS-TLIF was associated with longer operative time, less blood loss, less postoperative drainage and shorter postoperative time in bed; moreover, patients in the MIS-TLIF group had lower levels of serum creatine kinase on 1, 3 and 5 postoperative days. At the 3- and 6-month follow-up, Visual Analog Scale (VAS) scores of low back pain of patients in the MIS-TLIF group were significantly reduced and Japanese Orthopaedic Association (JOA) scores were increased, whereas the Oswestry Disability Index (ODI) showed no significant difference between the two groups. Conclusion Obese patients can achieve good efficacy with MIS-TLIF or PLIF treatment, but MIS-TLIF surgery showed longer operative time, fewer traumas and bleeding volume, less incidence of short-term pain, low complication rate and faster postoperative recovery.

    This study compared a noncontact infrared laser thermometer and 3 different brands of subcutaneous temperature transponding microchips with rectal thermometry in 50 rhesus macaques (Macaca mulatta). The data were analyzed by using intraclass correlation coefficients and limits of agreement. In addition, the technical capabilities and practicality of the thermometers in the clinical setting were reviewed. None of the alternative techniques investigated was equivalent to rectal thermometry in rhesus macaques. Temperatures obtained by using microchips had higher correlation and agreed more closely with rectal temperatures than did those obtained by the noncontact infrared method. However, transponding microchips did not yield consistent results. Due to difficulty in positioning nonsedated macaques in their homecage, subcutaneous microchips were not practical in the clinical setting. Furthermore, pair-housed macaques may be able to break or remove microchips from their cagemates.

    The standard of care in locally advanced rectal cancer is neoadjuvant chemoradiation (nCRT) followed by radical surgery. Response to nCRT varies among patients and pathological complete response is associated with better outcome. However, there is a lack of effective methods to select rectal cancer patients who would or would not have a benefit from nCRT. The utility of clinicopathological and radiological features are limited due to lack of adequate sensitivity and specificity. Molecular biomarkers have the potential to predict response to nCRT at an early time point, but none have currently reached the clinic. Integration of diverse types of biomarkers including clinicopathological and imaging features, identification of mechanistic link to tumor biology, and rigorous validation using samples which represent disease heterogeneity, will allow to develop a sensitive and cost-effective molecular biomarker panel for precision medicine in rectal cancer. Here, we aim to review the recent advance in tissue- and blood-based molecular biomarker research and illustrate their potential in predicting nCRT response in rectal cancer. PMID:28272347

    Local excision (LE) for rectal cancer is currently indicated for selected T1 stage tumors. However, preoperative chemoradiotherapy (CRT) for locally advanced rectal cancer not only improves local disease control, but also leads to a decrease in the stage and size of the primary mural tumor, along with a decrease in the risk of regional lymphadenopathy. The present study reports the outcome of a patient with T3N0M0 rectal cancer who was treated with LE following preoperative CRT. The distal pole of the tumor was located 2 cm from the anal verge. Preoperative pelvic radiotherapy of 50.4 Gy was administered in 28 fractions. Chemotherapy using 5-fluorouracil and leucovorin was administered during the first and last weeks of radiotherapy. The tumor response to CRT, was found to be marked at 7 weeks after CRT completion, and a complete response was presumed clinically. Transanal full-thickness LE was performed, and pathological examination revealed the absence of residual cancer cells. After 30 months of close follow-up, the patient was alive with no evidence of disease, and treatment-associated severe toxicities were not observed. Although a longer follow-up period is required, this case report suggests that LE may also be a feasible alternative treatment for T3 rectal cancer, which exhibits a marked response to preoperative CRT, particularly in elderly and comorbid patients contraindicated for radical surgery, or patients who are reluctant to undergo sphincter-ablation surgery.

    Nowadays, surgical resection is still the most effective treatment strategy for rectal carcinoma and one of the most important factors affecting whether the operation is successful or not is the surgical margin determination, especially in the distal rectal carcinoma which should take the sphincter-preserving issue into consideration. However, until recently no reliable evaluation method has been developed for this purpose. There are some shortcomings in intraoperative negative surgical margin assessment such as either lack of enough detailed information of biological tissues or the fact that it is time-consuming. Multiphoton microscopy (MPM)—nonlinear optical microscopy, which is based on the nonlinear optical process two-photon excited fluorescence (TPEF) and second harmonic generation (SHG), has the ability to label freely and noninvasively visualize tissue micro-architecture at the sub-cellular level. The advantage of providing high contrast and high resolution biomedical image in real time makes MPM have a wide range of applications in life sciences. In this study, we introduced MPM to identify the boundary between normal and abnormal rectal tissues. MPM images clearly exhibit biological tissue microstructure and its morphological changes in the regions of our interest, which enable it to determine the surgical margin in rectal carcinoma. It can be foreseen that once MPM imaging system is used in clinical examination, it will greatly improve the accuracy of surgical resection.

    Some interesting shifts have taken place in the diagnostic approach for detection of colorectal lesions over the past decade. This article accompanies the recent EURECCA consensus group reccomendations for optimal management of colon and rectal cancers. In summary, imaging has a crucial role to play in the diagnosis, staging assessment and follow up of patients with colon and rectal cancer. Recent advances include the use of CT colonography instead of Barium Enema in the diagnosis of colonoic cancer and as an alternative to colonoscopy. Modern mutlidetector CT scanning techniques have also shown improvements in prognostic stratification of patients with colonic cancer and clinical trials are underway testing the selective use of neoadjuvant therapy for imaging identified high risk colon cancers. In rectal cancer, high resolution MRI with a voxel size less or equal to 3 × 1 × 1 mm3 on T2-weighted images has a proven ability to accurately stage patients with rectal cancer. Moreover, preoperative identification of prognostic features allows stratification of patients into different prognostic groups based on assessment of depth of extramural spread, relationship of the tumour edge to the mesorectal fascia (MRF) and extramural venous invasion (EMVI). These poor prognostic features predict an increased risk of local recurrence and/or metastatic disease and should form the basis for preoperative local staging and multidisciplinary preoperative discussion of patient treatment options.

    Despite of its rich vascularization and extensive circulatory communication with neighboring organs, penile metastases are rare. Even more infrequent is a penile metastasis of rectum tumors. Since the first report of rectal carcinoma with metastasis to the penis (Ehbert 1870), approximately 50 cases have been reported, most of them from the USA, the remaining from Western Europe, the Middle East and Japan. The first Hungarian case is reported now of penile metastasis of a rectal carcinoma. The case of a 65-year-old man is presented: isolated penile metastasis discovered 4.5 years after the primary rectal cancer resection. IHC tissue diagnosis and detailed clinical investigations confirmed metastatic rectal adenocarcinoma. As our patient refused penectomy and KRAS mutation was proven, FOLFIRI chemotherapy was initiated without cetuximab. This was followed by chemoradiotherapy that resulted only in transient regression. Currently the patient receives the FOLFOX regimen. At present the patient is in good performance status,without pain. The size and the number of penile metastases have not shown significant changes. According to the literature the average survival of patients with penile metastases treated with radiochemotherapy is 8 months. New chemotherapeutic modalities may improve the survival.

    Lung metastasis is frequent in rectal cancer patients and has a poor prognosis, with an expected three-year survival rate of about 10%. Though western medicine has made great strides in the curative resection of liver metastases, resection of lung metastases has lagged far behind. Many preclinical studies have suggested that herbal treatments block metastasis, but few clinical studies have addressed this topic. We present the case of a 57-year-old Asian male with lung metastases from rectal cancer. He first underwent resection of the primary lesion (stage IIA, T3N0M0) and six cycles of adjuvant chemotherapy. Unfortunately, lung metastases were confirmed about one year later. Palliative chemotherapy was begun, but his disease continued to progress after three cycles and chemotherapy was halted. The patient was exclusively treated with herbal medicine-standardized allergen-removed Rhus verniciflua stokes extract combined with Dokhwaljihwang-tang (Sasang constitutional medicine in Korea). After seven weeks of herbal medicine treatment, the lung metastases were markedly improved. Regression of lung metastases has continued; also, the patient's rectal cancer has not returned. He has been receiving herbal medicine for over two years and very few side effects have been observed. We suggest that the herbal regimen used in our patient is a promising candidate for the treatment of lung metastases secondary to rectal cancer, and we hope that this case stimulates further investigation into the efficacy of herbal treatments for metastatic colorectal cancer patients.

    There are few reported cases of colorectal metastasis from cancers of other organs, particularly other segments of the colon. Here we describe the long-term survival of a 68-year-old male patient with metachronous rectal metastasis from cecal cancer who underwent repetitive resection and chemotherapy. The patient underwent ileocecal resection and hepatectomy for cecal cancer with liver metastasis (T3, N1a, M1a, Stage IVA) in 2006. The patient subsequently underwent splenectomy for splenic metastasis in 2007. In August 2008, barium enema revealed compression of the rectal wall, and abdominal computed tomography (CT) detected a mass along the rectum extending into the pelvis. Rectal metastasis from cecal cancer was suspected and Hartmann's operation with bilateral seminal vesicle dissection was performed. Histological examination of the excised tumor revealed moderately differentiated adenocarcinoma formed in the muscularis propria of the rectum and infiltrating the connective tissue between the seminal vesicle and rectum. However, no tumor was detected in the rectal mucosa or submucosa. These histological findings supported the diagnosis of rectal metastasis from cecal cancer. The patient has been monitored at our clinic for 60 months after surgical removal of the rectal metastasis. The findings from this case should alert oncologists to the potential danger of rectal metastasis from primary colon cancer and the benefits of timely complete resection in terms of improved patient outcomes.

    Twenty-five patients with invasive rectal cancer treated by transanal excision between 1978-1989 are presented. Two patients had poorly differentiated tumours and were converted to abdominoperineal resection and one patient had extensive liver metastases documented preoperatively. The remaining twenty-two, mean age 64 years, fulfilled the criteria for local treatment. Eighty-two percent of tumours were T1 or T2 stage. There was no operative mortality. Six complications in five patients occurred, none requiring surgical intervention. Five patients died of unrelated causes without evidence of recurrence at 4, 4, 14, 26 and 58 months. The length of follow-up for the surviving group (17 patients) was 16 to 115 months (mean 63 months). Two patients developed local recurrence at 32 and 60 months. Transanal excision can be curative for selected rectal cancers.

    The standard adjuvant treatment of cT3 and/or N+ rectal cancer is preoperative chemoradiation. However, there are many controversies regarding this approach. These controversies include the role of short course radiation, whether postoperative adjuvant chemotherapy is necessary for all patients, and if the type of surgery following chemoradiation should be based on the response rate. More accurate imaging techniques and/or molecular markers may help identify patients with positive pelvic nodes to reduce the chance of overtreatment with preoperative therapy. Will more effective systemic agents both improve the results of radiation, as well as modify the need for pelvic radiation? These questions and others remain active areas of clinical investigation.

    We analyzed proteomes of colon and rectal tumors previously characterized by the Cancer Genome Atlas (TCGA) and performed integrated proteogenomic analyses. Protein sequence variants encoded by somatic genomic variations displayed reduced expression compared to protein variants encoded by germline variations. mRNA transcript abundance did not reliably predict protein expression differences between tumors. Proteomics identified five protein expression subtypes, two of which were associated with the TCGA "MSI/CIMP" transcriptional subtype, but had distinct mutation and methylation patterns and associated with different clinical outcomes. Although CNAs showed strong cis- and trans-effects on mRNA expression, relatively few of these extend to the protein level. Thus, proteomics data enabled prioritization of candidate driver genes. Our analyses identified HNF4A, a novel candidate driver gene in tumors with chromosome 20q amplifications. Integrated proteogenomic analysis provides functional context to interpret genomic abnormalities and affords novel insights into cancer biology.

    Introduction Breast cancer metastases occurs in around 50% of all presentation. It is the second most common type of cancer to metastasise to the GI tract but this only occurs in less than 1% of cases. Presentation of case We report a case that underwent treatment for invasive lobular cancer (ILC) of the breast and 5 years later was found to have rectal and peritoneal metastasis. She is currently receiving palliative management including chemotherapy in the form of weekly Paclitaxel (Taxol®) and stenting to relieve obstruction. Conclusion There should be high clinical suspicion of bowel metastasis in patients presenting with positive faecal occult blood with or without bowel symptoms even if the incidence is less <1% of metastases, particularly in cases where the initial breast tumour was large, with positive axillary nodes.

    Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is a novel imaging modality that can be used to reflect the microcirculation, although its value in diagnosing rectal cancer is unknown. The present study aimed to explore the clinical application of DCE-MRI in the preoperative diagnosis of rectal cancer, and its correlation with tumor differentiation. To achieve this, 40 pathologically confirmed patients with rectal cancer and 15 controls were scanned using DCE-MRI. The Tofts model was applied to obtain the perfusion parameters, including the plasma to extravascular volume transfer (Ktrans), the extravascular to plasma volume transfer (Kep), the extravascular fluid volume (Ve) and the initial area under the enhancement curve (iAUC). Receiver-operating characteristic (ROC) curves were plotted to determine the diagnostic value. The results demonstrated that the time-signal intensity curve of the rectal cancer lesion exhibited an outflow pattern. The Ktrans, Kep, Ve, and iAUC values were higher in the cancer patients compared with controls (P<0.05). The intraclass correlation coefficients of Ktrans, Kep, Ve and iAUC, as measured by two independent radiologists, were 0.991, 0.988, 0.972 and 0.984, respectively (all P<0.001), indicating a good consistency. The areas under the ROC curves for Ktrans and iAUC were both >0.9, resulting in a sensitivity and specificity of 100% and 93.3% for Ktrans, and of 92.5%, and 93.3% or 100%, for iAUC, respectively. In the 40 rectal cancer cases, there was a moderate correlation between Ktrans and iAUC, and pathological differentiation (0.3rectal cancer and differentiation, and therefore may provide novel insights into the preoperative diagnosis of rectal cancer.

    Objective Compare pelvic structure location on MRI during maximal Valsalva among women with posterior prolapse and those with normal support. Methods and Materials Cases (n=37) had posterior vaginal wall (PVW) prolapse > +1cm. All underwent mid-sagittal, dynamic MRI. Structure locations (distal vagina, apex, perineal body, external anal sphincter) were determined. PVW length, levator and urogenital hiatus diameters, and prolapse diameter were measured. Results Cases had more caudal structures (p<0.001) and larger hiatus diameters (p<0.005); the posterior wall was longer, while the straight-line distance between the apex and distal vagina was shorter. In enteroceles, the apex was more ventrally displaced compared to rectoceles (p=0.003). Unlike apical descent (r=-0.3, p=0.1), PVW length and point Bp were correlated with MRI prolapse size (r=0.5, p=0.002; r=0.7, P<0.001, respectively). Conclusion At maximal Valsalva on MRI, structures are more caudal in women with posterior prolapse. The posterior vaginal wall is longer; this length strongly correlates with prolapse size.

    Perineal wound complications after abdomino-perineal rectal resection are frequent and clinically relevant for their impact on the length of hospitalization, costs, patients' quality of life and oncologic results. With the diffusion of the preoperative radiotherapy and the gradual shift to the extra-elevator technique, the perineal morbidity rate has increased. Many series describing different techniques of primary closure of the perineal defect have been published, but high-quality clinical studies, indicating which is the best option, are missing. A biologic mesh, associated if possible to an omentoplasty, seems to be sufficient to close the perineal defect after extra-elevator abdomino-perineal rectal resection. However, when the proctectomy is associated to the resection of other organs, as for example vagina or sacrum, resulting in an ample perineal defect, the vertical rectus abdominis flap seems to be the best option. If the perineal defect is smaller, the gracilis or gluteus flaps could be other valid alternatives.

    Diffuse optical spectroscopy imaging (DOSI) has shown great potential for the early detection of non-responding tumors during neoadjuvant chemotherapy in breast cancer, already one day after therapy starts. Patients with rectal cancer receive similar chemotherapy treatment. The rectum geometry and tissue properties of healthy and tumor tissue in the rectum and the requirement of surface contact impose constraints on the probe design. In this work we present the design of a DOSI probe with the aim of early chemotherapy/radiotherapy effectiveness detection in rectal tumors. We show using Monte Carlo simulations and phantom measurements that the colon tissue can be characterized reliably using a source-detector separation in the order of 10 mm. We present a design and rapid prototype of a probe for DOSI measurements that can be mounted on a standard laparoscope and that fits through a standard rectoscope. Using predominantly clinically approved components we aim at fast clinical translation.

  11. Pelvic Floor Support Defect in Apical Anterior Vaginal Prolapse with Cervical Hypertrophy. Review with Case Report in a 20-year-old Cadaver

    PubMed Central

    2015-01-01

    Apical anterior vaginal wall prolapse (AVWP) with central defect is uncommon in young non hysterectomized patients causing considerable mortality after the fourth decade of life. Its high propensity to recurrence poses the greatest challenge to pelvic reconstructive surgeons. Approximately 40% of women with prolapse have hypertrophic cervical elongation and the extent of elongation increases with greater degrees of prolapse. Women with prolapse either have inherent hypertrophic elongation of the cervix which predisposes them to prolapse or the downward traction in prolapse leads to cervical elongation. The Pelvic Organ Prolapse Quantification (POP-Q) examination includes measurement of the location of the posterior fornix (point D) with the assumption that this measurement is associated with cervical elongation. Multifocal site involvement with apical and perineal descent primarily afflicts elderly, postmenopausal women after the fourth decade while cervical hypertrophic elongation with prolapse is observed in younger women less than 40 years of age. A review of the anatomical implication of the association of cervical hypertrophy in prolapse is carried out in this article. We observed a combination of distension type anterior vaginal prolapse with apical descent and cervical hypertrophy in a 20-year-old cadaver during routine dissection for undergraduate medical students at Sikkim Manipal Institute of Medical Sciences in 2013. Distension type anterior vaginal prolapse with central defect is rarer as most reported cases are of the displacement type, paravaginal defect. Hypertrophic cervical elongation is either the cause or consequence of prolapse and its identification before reconstructive surgery is paramount as uterine suspension in the face of cervical elongation is contraindicated. Inappropriate identification of all support defects and breaking of tissues is the primary cause of failure of laparoscopic pelvic reconstructive surgery. PMID:26557506

    Objective To identify predictors of positive circumferential resection margin following rectal cancer resection in the United States. Background Positive circumferential resection margin is associated with a high rate of local recurrence and poor morbidity and mortality for rectal cancer patients. Prior study has shown poor compliance with national rectal cancer guidelines, but whether this finding is reflected in patient outcomes has yet to be shown. Methods Patients who underwent resection for stage I-III rectal cancer were identified from the 2010-2011 National Cancer Database. The primary outcome was a positive circumferential resection margin. The relationship between patient, hospital, tumor, and treatment-related characteristics was analyzed using bivariate and multivariate analysis. Findings A positive circumferential resection margin was noted in 2,859 (17.2%) of the 16,619 patients included. Facility location, clinical T and N stage, histologic type, tumor size, tumor grade, lymphovascular invasion, perineural invasion, type of operation, and operative approach were significant predictors of positive circumferential resection margin on multivariable analysis. Total proctectomy had nearly a 30% increased risk of positive margin compared to partial proctectomy (OR 1.293, 95%CI 1.185-1.411) and a laparoscopic approach had nearly 22% less risk of a positive circumferential resection margin compared to an open approach (OR 0.882, 95%CI 0.790-0.985). Interpretation Despite advances in surgical technique and multimodality therapy, rates of positive circumferential resection margin remain high in the United States. Several tumor and treatment characteristics were identified as independent risk factors, and advances in rectal cancer care are necessary to approach the outcomes seen in other countries.

    Objectives The purpose of Project Gel was to determine the safety and acceptability of rectal microbicides in young men who have sex with men (MSM) and transgender women (TGW) at risk of HIV infection. Methods MSM and TGW aged 18–30 years were enrolled at three sites; Pittsburgh, PA; Boston, MA; and San Juan, PR. Stage 1A was a cross-sectional assessment of sexual health and behavior in MSM and TGW. A subset of participants from Stage 1A were then enrolled in Stage 1B, a 12-week evaluation of the safety and acceptability of a placebo rectal gel. This was followed by the final phase of the study (Stage 2) in which a subset of participants from Stage 1B were enrolled into a Phase 1 rectal safety and acceptability evaluation of tenofovir (TFV) 1% gel. Results 248 participants were enrolled into Stage 1A. Participants’ average age was 23.3 years. The most common sexually transmitted infection (STIs) at baseline were Herpes simplex (HSV)-2 (16.1% by serology) and rectal Chlamydia trachomatis (CT) (10.1% by NAAT). 134 participants were enrolled into Stage 1B. During the 12 week period of follow-up 2 HIV, 5 rectal CT, and 5 rectal Neisseria gonorrhea infections were detected. The majority of adverse events (AEs) were infections (N = 56) or gastrointestinal (N = 46) and were mild (69.6%) or moderate (28.0%). Of the participants who completed Stage 1B, 24 were enrolled into Stage 2 and randomized (1:1) to receive TFV or placebo gel. All participants completed Stage 2. The majority of AEs were gastrointestinal (N = 10) and of mild (87.2%) or moderate (10.3%) severity. Conclusions In this study we were able to enroll a sexually active population of young MSM and TGW who were willing to use rectal microbicides. TFV gel was safe and acceptable and should be further developed as an alternative HIV prevention intervention for this population. Trial Registration ClinicalTrials.gov NCT01283360 PMID:27362788

    Background Unacceptable adverse effects, contraindications to and/or ineffectiveness of World Health Organization step III “pain ladder” drugs causes needless suffering among a population of cancer patients. Successful management of severe cancer pain may require invasive treatment. However, a patient’s refusal of an invasive procedure necessitates that clinicians consider alternative options. Objective Intrathecal bupivacaine delivery as a viable treatment of intractable pain is well documented. There are no data on rectal bupivacaine use in cancer patients or in the treatment of cancer tenesmoid pain. This study aims to demonstrate that bupivacaine administered rectally could be a step in between the current treatment options for intractable cancer pain (conventional/conservative analgesia or invasive procedures), and to evaluate the effect of the mode of administration (intrathecal versus rectal) on the bupivacaine plasma concentration. Cases We present two Caucasian, elderly inpatients admitted to hospice due to intractable rectal/tenesmoid pain. The first case is a female with vulvar cancer, and malignant infiltration of the rectum/vagina. Bupivacaine was used intrathecally (0.25–0.5%, 1–2 mL every 6 hours). The second case is a female with ovarian cancer and malignant rectal infiltration. Bupivacaine was adminstered rectally (0.05–0.1%, 100 mL every 4.5–11 hours). Methods Total bupivacaine plasma concentrations were determined using the high-performance liquid chromatography-ultraviolet method. Results Effective pain control was achieved with intrathecal bupivacaine (0.077–0.154 mg·kg−1) and bupivacaine in enema (1.820 mg·kg−1). Intrathecal bupivacaine (0.5%, 2 mL) caused a drop in blood pressure; other side effects were absent in both cases. Total plasma bupivacaine concentrations following intrathecal and rectal bupivacaine application did not exceed 317.2 ng·mL−1 and 235.7 ng·mL−1, respectively. Bupivacaine elimination was

    Clinically symptomatic late injury to the rectal wall occurs in about one third of patients with prostate cancer treated with external beam irradiation. Reducing the physical dose to the anterior rectal wall without a similar reduction in the posterior peripheral zone is difficult because of the proximity of these structures. Based on our previous observations that intrarectal application of amifostine resulted in very high concentrations of amifostine and its active metabolite WR-1065 in the rectal wall of Copenhagen rats, the authors initiated a phase I clinical trial in 1998. Twenty-nine patients with localized prostate cancer were accrued. Eligibility criteria included histologically confirmed adenocarcinoma, a Karnofsky performance status of > or =70, and no pelvic lymphadenopathy or distant metastases. The total dose to the prostate was 70.2 Gy (20 patients) and 73.8 Gy (9 patients). Therapy was delivered using a 4-field axial technique and 3-dimensional conformal planning. Amifostine was administered intrarectally as an aqueous solution 30 minutes before irradiation on the first 15 days of therapy. Amifostine dose was escalated, in cohorts, from 500 mg to 2,500 mg. Toxicity was evaluated using the Radiation Therapy Oncology Group late morbidity scale. All patients completed therapy with no amifostine-related toxicity at any dose level. The application was feasible and well tolerated. With a median follow-up time of 21 months, 9 patients (33%) had rectal bleeding (8 grade 1, 1 grade 2). Four patients (14%) had symptoms suggestive of radiation injury, which proved to be secondary to nonrelated processes. These included preexisting nonspecific proctitis (1 patient), diverticular disease of the sigmoid colon, rectal polyp (1 patient), and ulcerative colitis (1 patient). Symptoms developed significantly more often in patients receiving 500 to 1,000 mg than in patients receiving 1,500 to 2,500 mg amifostine (7 of 14 [50%] versus 2 of 13 [15%]; P =.0325, 1-sided

    Purpose: In our Phase II prostate cancer Adaptive Radiation Therapy (ART) study, the highest possible dose was selected on the basis of normal tissue tolerance constraints. We analyzed rectal toxicity rates in different dose levels and treatment groups to determine whether equivalent toxicity rates were achieved as hypothesized when the protocol was started. Methods and Materials: From 1999 to 2002, 331 patients with clinical stage T1 to T3, node-negative prostate cancer were prospectively treated with three-dimensional conformal adaptive RT. A patient-specific confidence-limited planning target volume was constructed on the basis of 5 CT scans and 4 sets of electronic portal images after the first 4 days of treatment. For each case, the rectum (rectal solid) was contoured in its entirety. The rectal wall was defined by use of a 3-mm wall thickness (median volume: 29.8 cc). The prescribed dose level was chosen using the following rectal wall dose constraints: (1) Less than 30% of the rectal wall volume can receive more than 75.6 Gy. (2) Less than 5% of the rectal wall can receive more than 82 Gy. Low-risk patients (PSA < 10, Stage {<=} T2a, Gleason score < 7) were treated to the prostate alone (Group 1). All other patients, intermediate and high risk, where treated to the prostate and seminal vesicles (Group 2). The risk of chronic toxicity (NCI Common Toxicity Criteria 2.0) was assessed for the different dose levels prescribed. HIC approval was acquired for all patients. Median follow-up was 1.6 years. Results: Grade 2 chronic rectal toxicity was experienced by 34 patients (10%) (9% experienced rectal bleeding, 6% experienced proctitis, 3% experienced diarrhea, and 1% experienced rectal pain) at a median interval of 1.1 year. Nine patients (3%) experienced grade 3 or higher chronic rectal toxicity (1 Grade 4) at a median interval of 1.2 years. The 2-year rates of Grade 2 or higher and Grade 3 or higher chronic rectal toxicity were 17% and 3%, respectively. No

    A spongiform epidemic is upon us - myocardial trabeculae are everywhere as left ventricular noncompaction (LVNC) ingratiates itself into modern day cardiology. Current understanding of the condition is evolving but remains incomplete, and brings to mind the chronicles of another great cardiac story: mitral valve prolapse. Anecdote suggests that many individuals with prominent trabeculae may be being falsely labelled with a disease - LVNC - using poor echocardiographic and cardiovascular magnetic resonance criteria. Until we have robust diagnostic criteria, aetiology, clinicopathological significance and prognosis, the risk of casualties from ascertainment bias will remain. We should look to history and learn from past mistakes - specifically from the mitral valve prolapse story to show the way forward for LVNC. Meanwhile, clinicians (and patients) should be wary, bearing in mind the possibility that they might be seeing LVNNC - left ventricular non-noncompaction.

    Histological and histochemical analysis of biopsy samples of pubococcygeus muscle obtained from asymptomatic women and from women with stress incontinence of urine, with or without genitourinary prolapse, have been compared. In the asymptomatic women both age and parity appeared to be related to the morphological features of the samples and in particular those obtained from the posterior part of the pubococcygeus. In the symptomatic women there was a significant increase in the number of muscle fibres showing pathological damage which were obtained from the posterior part of the pelvic floor. The range of diameters of both Type I and Type II fibres obtained from this region was significantly different between symptomatic and asymptomatic women. These findings may be attributable to partial denervation of the pelvic floor in patients with urinary stress incontinence with or without genital tract prolapse.

    One hundred and sixty-six young military man with mitral valve prolapse (MVP) aged 19.2+/-0.8 years were examined. Complex system approach to health status was applied to study clinico-functional features of this condition in young military men. The study found that clinico-functional manifestations of MVP in young military men reflected a multifocal character of dysadaptation during the first stages of military service. Conditions of professional military activity potentiate permanent progress of crisp prolapse as well as the severity of mitral regurgitation, structural and functional myocardial alterations, and myocardial electric instability increasing in the presence of abnormal cardiac chords under the influence of a prominent vegetative dysfunction. The reserve of the cardiorespiratory system and the entire organism in military men with MVP was lowered. The study registered inadequate hemodynamic responses to functional orthostatic test and physical load test, typical for hyperventilation syndrome.

    The E-cadherin-catenin complex provides cell-cell adhesion. In order for a carcinoma to metastasize, cancer cells must let go of their hold of neighboring cells in the primary tumor. The presence of components of the E-cadherin-catenin complex in 246 rectal adenocarcinomas was examined by immunohistochemistry and compared to their presence in 219 colon carcinomas. The expression data were correlated to clinical information from the patients' records. There were statistically significant differences in protein expression between the rectal and the colon carcinomas regarding membranous beta-catenin, gamma-catenin, p120-catenin, and E-cadherin, as well as nuclear beta-catenin. In the rectal carcinomas, there was a significant inverse association between the expression of p120-catenin in cell membranes of the primary tumors and the occurrence of local recurrence, while membranous protein expression of beta-catenin was inversely related to distant metastases.

    The aim of this study was to compare the contractility of the anterior vaginal muscularis (AVM) from women with and without pelvic organ prolapse (POP). In vitro experiments were performed to measure the peak force generated in response to potassium chloride (KCl; 125 mmol/L) and phenylephrine by AVM tissue from women with and without POP. Cross-sectional areas and co-localization of α1A adrenergic receptor protein with smooth muscle α-actin in AVM strips were determined by histology and immunofluorescence, respectively. There were no differences in the mean amplitude of force generated in response to KCl normalized to either wet weight or muscle cross-sectional area (mN/mm2) between women with and without POP (P > .30). However, AVM from women with prolapse produced a significantly higher mean force to KCl normalized to total cross-sectional area compared to controls (P = .007). While the control samples demonstrated a consistent response to phenylephrine, there was no response to this stimulant generated by AVM tissue from women with POP. The proportion of co-localized α1A adrenergic receptors with smooth muscle α actin in AVM tissue was significantly less in women with POP compared to normal controls (P < .0001). Although there was significantly greater tissue stress generated by AVM from women with prolapse compared to controls, there were no differences in muscle stress. Absent response to phenylephrine by AVM from women with prolapse may be related to a lower expression of α1A adrenergic receptors in vaginal smooth muscle. PMID:21193802

    A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether it is best in a patient with posterior leaflet prolapse to resect tissue from the posterior leaflet or to preserve the leaflet tissue by only adding neochordal reconstruction. Altogether, 279 papers were found using the reported search, of which 16 represented the best evidence to answer the clinical question. The authors, journal, date, country of publication, patient group, study type, relevant outcomes and results of these papers are tabulated. The results of the reported studies provided interesting results. All the studies identified were retrospective. Seven papers reported their results on mitral valve (MV) repair with neochordae. These papers included study groups of 74 to 662 patients. The spanned operation dates were from 1983 to 2008. The main disease was degenerative valve disease. The authors performed MV repair using neochordae with or without a ring. The 5-year freedom rate from reoperation was from 94.3 to 98.7%, the 10-year freedom rate from reoperation was from 81.7 to 94.7%, the 15-year freedom rate from reoperation was 92%, and the 18-year freedom rate from reoperation was 90.2%. The 5-year survival rate was from 96.6 to 96.9%, the 10-year survival rate was from 88 to 89.3%, the 15-year survival rate was 84%, and the 18-year survival rate was 66.8%. Seven papers reported their results on MV repair with resection techniques. These papers included patient groups of 162 to 3074 patients. Operation dates were from 1970 to 2008. The authors performed MV repair with quadrangular resection, plus or minus a sliding annuloplasty. The 5-year freedom rate from reoperation was from 93.9 to 98%, the 10-year freedom rate from reoperation was from 93 to 98.5%, and the 20-year freedom rate from reoperation was from 88 to 96.9%. The 5-year survival rate was from 86.9 to 96%, the 10-year survival rate was from 79 to 93.5%, the 15-year

    expression of the anti-inflammatory cytokine IL-10 was observed in Restorelle as compared to Gynemesh PS (P=0.011). Conclusions The host response to mesh consists predominantly of activated, pro-inflammatory, M1 macrophages at 12 weeks post-surgery. However, this response is attenuated with implantation of lighter weight, higher porosity mesh. While additional work is required to establish causal relationships, these results suggest a link between the host inflammatory response, mesh textile properties, and clinical outcomes in the repair of pelvic organ prolapse.

    Abstract Given the low incidence and delayed diagnosis, ureterocele management in the adult population is poorly described in the literature. Moreover, there is only one case report characterizing the condition with prolapse in an adult male. Approaches to therapy include transurethral incision or puncture with or without a combined percutaneous approach, and excision with or without partial nephrectomy for a duplicated system with a nonfunctioning upper pole moiety. We present a case of prolapsed, single intravesical ureterocele in a man presenting with hematuria and lower urinary-tract symptoms. A 54-year-old man with no significant medical history presents with increasing nocturia and urinary hesitancy. The development of gross hematuria prompted urologic evaluation. On imaging, the patient was found to have 4.3 × 3.3 cm bladder mass consistent with a prolapsed ureterocele that was managed by transurethral excision with a cutting loop. Postoperatively, the patient's symptoms resolved completely without complication. We suggest that complete transurethral ureterocele excision is an effective, definitive treatment option.

    The aim of the study is to evaluate the impact of pelvic organ prolapse (POP) on sexual function in women with urinary incontinence (UI). In this retrospective, case-cohort study, we reviewed the medical records of all women evaluated for UI between March and November 2003. All patients completed the short forms of the Urogenital Distress Inventory, Incontinence Impact Questionnaire, and Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire. Women with stage two or greater POP, as determined by the pelvic organ prolapse quantification (POPQ) system, were compared to women with stage 0 or 1 POP. Sixty-nine women with POP and 47 women without POP were included. Patient demographics did not differ between the two groups. Women with POP were significantly more likely to report absence of libido (53% versus 30%, P=0.02), lack of sexual excitement during intercourse (46% versus 27%, P=0.05), and that they rarely experienced orgasm during intercourse (49% versus 30%, P=0.05). In conclusion, women with POP in addition to UI are more likely to report decreased libido, decreased sexual excitement, and difficulty achieving orgasm during intercourse when compared to women with UI alone.

At 21 weeks' gestation, a double renal system with an intravesical ureterocele obstructing the bladder outlet was diagnosed, causing severe megacystis, bilateral hydronephrosis and progressive oligohydramnios. Ultrasound evaluation following referral to our center confirmed severe bilateral hydronephrosis with pelvic and calyceal dilatation, but amniotic fluid volume was normal and the ureterocele was not visualized in the bladder. Instead, a cystic mass within the external genitalia was observed, suggestive of a prolapsed ureterocele, causing intermittently severe obstruction of the urethra. The parents were counseled about the uncertain prognosis and fetal surgery to decompress the urinary system was proposed. The procedure involved firing a contact diode laser until perforation of the ureterocele was achieved. Following laser surgery, resolution of megacystis, reduction of hydronephrosis and normalization of amniotic fluid volume were observed. Our report demonstrates that fetoscopic decompression of a distal urethral obstruction is feasible in the rare event of congenital prolapsed ureterocele.

    Introduction Pelvic organ prolapse is a multifactorial disease. Aim was to evaluate the effect of the whole surgical correction of pelvic floor on hydronephrosis due to severe prolapse. Patients and Methods A retrospective case study on 250 patients presenting with severe uterovaginal prolapse was carried out. Results Hydronephrosis was found in 32/234 (13.7 %). All patients underwent hysterectomy, vaginal apex axial suspension, posterior and anterior repair, vaginally. Prepubic TICT (Tension free Incontinence Cystocoele Treatment) was done in 38 cases (3 with hydronephrosis). Of the 32/234 (13.7 %) patients with hydronephrosis, 18/32 (56.25%) had complete resolution of hydronephrosis after treatment, 14/32 (43.75%) had a reduction of calico-pyelic dilatation, among them 8 patients had a second degree and 6 a first degree of hydronephrosis. Conclusions Vaginal-hysterectomy, axial apex suspension, anterior and posterior repair resulted in either complete resolution or improvement of hydronephrosis. Prepubic TICT did not interfere on mechanical obstruction and maintained postoperative continence in the event of occult Stress Urinary Incontinence (SUI). PMID:26888700

    Purpose: We have previously shown that intensity-modulated radiotherapy (IMRT) can reduce dose to small bowel, bladder, and bone marrow compared with three-field conventional radiotherapy (CRT) technique in the treatment of rectal cancer. The purpose of this study was to review our experience using IMRT to treat rectal cancer and report patient clinical outcomes. Methods and Materials: A retrospective review was conducted of patients with rectal cancer who were treated at Mayo Clinic Arizona with pelvic radiotherapy (RT). Data regarding patient and tumor characteristics, treatment, acute toxicity according to the Common Terminology Criteria for Adverse Events v 3.0, tumor response, and perioperative morbidity were collected. Results: From 2004 to August 2009, 92 consecutive patients were treated. Sixty-one (66%) patients were treated with CRT, and 31 (34%) patients were treated with IMRT. All but 2 patients received concurrent chemotherapy. There was no significant difference in median dose (50.4 Gy, CRT; 50 Gy, IMRT), preoperative vs. postoperative treatment, type of concurrent chemotherapy, or history of previous pelvic RT between the CRT and IMRT patient groups. Patients who received IMRT had significantly less gastrointestinal (GI) toxicity. Sixty-two percent of patients undergoing CRT experienced {>=}Grade 2 acute GI side effects, compared with 32% among IMRT patients (p = 0.006). The reduction in overall GI toxicity was attributable to fewer symptoms from the lower GI tract. Among CRT patients, {>=}Grade 2 diarrhea and enteritis was experienced among 48% and 30% of patients, respectively, compared with 23% (p = 0.02) and 10% (p = 0.015) among IMRT patients. There was no significant difference in hematologic or genitourinary acute toxicity between groups. In addition, pathologic complete response rates and postoperative morbidity between treatment groups did not differ significantly. Conclusions: In the management of rectal cancer, IMRT is associated with a

    Pelvic Organ Prolapse (POP) is a major clinical burden affecting 25% of women, with vaginal delivery a major contributing factor. We hypothesised that increasing parity weakens the vagina by altering the extracellular matrix proteins and smooth muscle thereby leading to POP vulnerability. We used a modified POP-quantification (POP-Q) system and a novel pressure sensor to measure vaginal wall weakness in nulliparous, primiparous and multiparous ewes. These measurements were correlated with histological, biochemical and biomechanical properties of the ovine vagina. Primiparous and multiparous ewes had greater displacement of vaginal tissue compared to nulliparous at points Aa, Ap and Ba and lower pressure sensor measurements at points equivalent to Ap and Ba. Vaginal wall muscularis of multiparous ewes was thinner than nulliparous and had greater elastic fibre content. Collagen content was lower in primiparous than nulliparous ewes, but collagen organisation did not differ. Biomechanically, multiparous vaginal tissue was weaker and less stiff than nulliparous. Parity had a significant impact on the structure and function of the ovine vaginal wall, as the multiparous vaginal wall was weaker and had a thinner muscularis than nulliparous ewes. This correlated with “POP-Q” and pressure sensor measurements showing greater tissue laxity in multiparous compared to nulliparous ewes. PMID:28374826

    Inflammatory myofibroblastic tumors are neoplasms characterized by spindle cell proliferation and a fiboinflammatory vascular stroma. Herein, we presented the successful treatment of a rectal inflammatory myofibroblastic tumor in an 11-year-old boy who presented with diarrhea and abdominal pain of 1(1/2) months duration and an appendiceal inflammatory myofibroblastic tumor in a 29-year-old man presented with recurrent abdominal pain of two months duration with associated tenderness and rebound tenderness in the right lower abdomen. Histologically, our cases had inflammatory myofibroblastic tumors very similar to that of other sites; the spindle cells were positive for vimentin and muscle-specific actin.

    A newly devised enterocompressor facilitates low rectal anastomosis in children with Hirschsprung's disease. This simple surgical instrument, composed of two semicylindrical valves, a hinge, and a regulating screw, maintains intestinal anastomoses properly placed and produces spur crushing. In addition, it is inexpensive and reusable. The enterocompressor, used in 33 primary and 15 secondary Duhamel operations, and applied to normalize intestinal transit in 10 colectomies, provided adequate anastomosis and prevented leakage of intestinal contents. This enterocompressor can be used safely in children as young as six months of age.

    Patient: Female, 60 Final Diagnosis: Gastroesophageal carcinoma with rectal metastasis Symptoms: Bloating • constipation • weight loss Medication: — Clinical Procedure: Endoscopy • flexible sigmoidoscopy • lower endoscopic ultrasound Specialty: Gastroenterology and Hepatology Objective: Unusual clinical course Background: Gastroesophageal cancers, previously considered rare, are rapidly increasing worldwide. We present here a unique case of gastroesophageal carcinoma with metastasis to the rectum. Case Report: A 60-year-old female patient presented with constipation, bloating, and weight loss of 4-month duration. She had undergone sleeve gastrectomy 6 years before. Endoscopies performed revealed a friable-looking mucosa in the lower esophagus and a polypoid rectal mass. Histopathological examination from both the esophageal and rectal lesions revealed poorly differentiated adenocarcinoma cells. Immunohistochemistry stain from both specimens was positive for CK7 supporting the gastric site primary with metastasis to the rectum. Further evaluation also revealed metastasis to bone and malignant pleural effusion. Chemotherapy with palliative intent was initiated. Conclusions: Colorectal metastasis is commonly seen from cancers of the breast, stomach, melanoma, kidney, prostate, and ovaries. However, colorectal metastasis from gastroesophageal cancer has never been reported in the medical literature. Diagnosis relies on histopathologic examination and immunohistochemical staining of the tumor. Treatment depends on the tumor stage. Tumors with widespread metastatic disease are candidates for palliative chemotherapy. PMID:27558656

    Identifying subjects with cystic fibrosis (CF) who may benefit from cystic fibrosis transmembrane conductance regulator (CFTR)-modulating drugs is time-consuming, costly, and especially challenging for individuals with rare uncharacterized CFTR mutations. We studied CFTR function and responses to two drugs-the prototypical CFTR potentiator VX-770 (ivacaftor/KALYDECO) and the CFTR corrector VX-809 (lumacaftor)-in organoid cultures derived from the rectal epithelia of subjects with CF, who expressed a broad range of CFTR mutations. We observed that CFTR residual function and responses to drug therapy depended on both the CFTR mutation and the genetic background of the subjects. In vitro drug responses in rectal organoids positively correlated with published outcome data from clinical trials with VX-809 and VX-770, allowing us to predict from preclinical data the potential for CF patients carrying rare CFTR mutations to respond to drug therapy. We demonstrated proof of principle by selecting two subjects expressing an uncharacterized rare CFTR genotype (G1249R/F508del) who showed clinical responses to treatment with ivacaftor and one subject (F508del/R347P) who showed a limited response to drug therapy both in vitro and in vivo. These data suggest that in vitro measurements of CFTR function in patient-derived rectal organoids may be useful for identifying subjects who would benefit from CFTR-correcting treatment, independent of their CFTR mutation.

One of the aims of the society is to establish guidelines to the treatment of these diseases. These guidelines are based on the international literature and on the best available evidence. Clinical practice guidelines are one of the most important instruments to provide therapeutic decision-making support, based on the best scientific evidence available at the time. Guidelines are advisory and not prescriptive, susceptible to continual variations secondary to innovations and new scientific evidence. These guidelines are a guide for all colo-rectal surgeons and physicians who approach anal cancer.

    The aim of adjuvant chemotherapy is the destruction of micrometastases after surgical removal of a malignant tumor. This treatment modality is gaining in importance in the light of experimental data and lcinical success in pediatric tumors. Results of ongoing studies in colo-rectal cancer show a marginal effect of prophylactic treatment with 5-fluorouracil. The treatment benefits in trials with historical controls are much greater than in studies with simultaneous controls. Use of historical controls is therefore of doubtful value. Ongoing trials use the combination of 5-fluorouracil and methyl-CCNU, which has been shown to double the remission rate in advanced gastrointestinal cancer. Adjuvant chemotherapy of colo-rectal cancer is still experimental and justified only in the framework of clinical trials.

    Secondary malignancy of the penis is a rare clinical condition, often associated with disseminated genitourinary malignancies. The prognosis is poor and the treatment options include penectomy, local surgical excision, radiation therapy, chemotherapy and supportive therapy. Neither of these therapeutic options lead to superior treatment outcomes in the literature. The authors report the case of a 66 year-old man with a metastasis to the glans penis from a rectal adenocarcinoma, diagnosed two years after radical treatment for primary disease. The patient underwent palliative treatment with radiotherapy and chemotherapy, remaining asymptomatic and disease-free at one year follow-up. Close follow-up of patients with history of rectal adenocarcinoma is very important. Radiochemotherapy is a feasible and effective therapeutic option for penile metastasis, addressing both disease control and symptomatic improvement.

    Purpose: The aim of this study was to determine the risk factors for late gastrointestinal (GI) morbidity after hypofractionated carbon ion radiotherapy (C-ion RT) for prostate cancer. Methods and Materials: Between April 2000 and November 2003, a Phase II clinical trial of C-ion RT with a total dose of 66 GyE in 20 fractions was performed on 175 patients with prostate cancer, and the correlations of clinical and dosimetric parameters with the incidence of late GI toxicity in 172 patients who survived for more than 18 months were investigated. Results: Although no Grade 3-4 late morbidities of the rectum were observed, Grade 1 and 2 morbidities developed in 23 (13%) and 4 (2%) patients, respectively. Dose-volume histogram analysis revealed that the percentage of rectal volume receiving 50% of the prescribed dose (V50) was significantly higher in patients with rectal toxicity than without toxicity (13.2 {+-} 5.6% with toxicity; 11.4 {+-} 4.0% without toxicity, p = 0.046). Multivariate analysis demonstrated that the use of anticoagulation therapy (p = 0.010) and rectal V50 (p = 0.012) were significant risk factors for the occurrence of Grade 1-2 late GI toxicity. Conclusions: Although C-ion RT with hypofractionation yielded favorable results regarding late GI complication, dosimetric parameter was a very important factor in the occurrence of rectal bleeding after C-ion RT as well as photon beam RT. Our results provide useful information for physicians applying charged particle RT in the treatment of prostate cancer.

    Critical care nurses assess and treat clinical conditions associated with inadequate oxygenation. Changes in regional organ (gut) blood flow are believed to occur in response to a decrease in oxygenation. Although the stomach is a widely accepted monitoring site, there are multiple methodological and measurement issues associated with the gastric environment that limit the accuracy of P CO2 detection. The rectum may provide nurses with an alternative site for monitoring changes in P CO2 without the limitations associated with gastric monitoring. This pilot study used a repeated measures design to examine changes in gastric and rectal P CO2 during elective coronary artery bypass grafting with cardiopulmonary bypass (CPB) and in the immediate 4-hr postoperative period in 26 subjects. The systemic indicators explained little variation in the regional indicators during protocol. A comparison of rectal and gastric P CO2 revealed no statistically significant differences in the direction or magnitude of change over any phase of cardiac surgery (baseline, CPB, post-CPB). A reduction in both rectal and gastric P CO2 occurred during CPB, and both values trended upward during the post-CPB phase. However, poor correlation and agreement was found between the measures of P CO2 at the two sites. Although clinically important, the cause is unclear. Possible explanations include variation in CO2 production between the gastric and rectal site, differences in sensitivity of the two monitoring instruments, or the absence of hemodynamic complications, which limited the extent of change in P CO2. Further investigation using patients with more profound changes in oxygenation are needed to identify response patterns and possible mechanisms.

    Rectal cancer treatment has undergone major changes over the last 15 years with a focus on individualized care based around MRI assessment of the relationship of the tumour to the mesorectal fascia, improved surgical techniques and targeted use of pre-operative oncological therapies in patients with locally advanced disease. The recognition that some tumours responded completely to pre-operative chemoradiotherapy, and the selective use of a non-operative policy has led to a quest to further identify those patients and their tumour in whom this approach could be used, irrespective of MRI stage. With no clear patient factors identified, the tumour and its gene expression has become a target for research to identify individual single-nucleotide polymorphisms, which may indicate a response to specific treatment, or not. To date some agents have been identified and trialed, such as cetuximab, with individual tumours being assessed for response allowing directed treatment. The reviewed paper by Sebio and colleagues report a study that links polymorphisms in the DNA repair gene XRCC1 with response to neoadjuvant 5-Fluorouracil treatment in rectal cancer patients. However, genetic heterogeneity alone may not explain the variations of drug response and environmental factors may lead to epigenetic effects and therefore alter responses. Therefore whilst this study demonstrates the impact of different single nucleotide polymorphisms (SNPs), it is only one step forward, but perhaps a step in the right direction. PMID:28149883

    Purpose: This retrospective study analyzed the effect of the activity of high-dose-rate (HDR) {sup 192}Ir source on late rectal bleeding after HDR intracavitary radiotherapy (ICRT) in patients with uterine cervix cancer. Methods and Materials: One hundred thirty-two patients who underwent HDR-ICRT and external beam radiotherapy (EBRT) were analyzed. The rectal point dose in ICRT was calculated by inserting a lead wire into the rectal lumen and summed with the whole-pelvic EBRT dose. The rectal biologic effective dose (BED) was calculated. The relationship between averaged source activity or the BED and late rectal bleeding were analyzed. Results: Three-year actuarial rectal bleeding probabilities were 46% ({>=}100 Gy{sub 3}) and 18% ({<=} 100 Gy{sub 3}), respectively (p < 0.005). When patients were divided into four groups according to rectal BED ({>=} or {<=}100 Gy{sub 3}) and source activity ({>=} or {<=}2.4 cGy.m{sup 2}.h{sup -1}), the group with both a high BED and high activity showed significantly greater probability (58% at 3 years; p < 0.005). It was noted that the probability of the group with BED of 100 Gy{sub 3} or greater was high, but that was not the case with 2.4 cGy.m{sup 2}.h{sup -1} or less. Conclusion: This is the first clinical report concerning the source activity effect of HDR {sup 192}Ir on late rectal bleeding in patients undergoing HDR-ICRT. This suggests that when source activity is higher than 2.4 cGy.m{sup 2}.h{sup -1}, ICRT should be performed with more caution not to exceed 100 Gy{sub 3} in total.

    Prevalent HSV-2 infection increases the risk of HIV acquisition both in men and women even in asymptomatic subjects. Understanding the impact of HSV-2 on the mucosal microenvironment may help to identify determinants of susceptibility to HIV. Vaginal HSV-2 infection increases the frequency of cells highly susceptible to HIV in the vaginal tissue of women and macaques and this correlates with increased susceptibility to vaginal SHIV infection in macaques. However, the effect of rectal HSV-2 infection on HIV acquisition remains understudied. We developed a model of rectal HSV-2 infection in macaques in combination with rectal SIVmac239Δnef (SIVΔnef) vaccination and our results suggest that rectal HSV-2 infection may increase the susceptibility of macaques to rectal SIVmac239 wild-type (wt) infection even in SIVΔnef-infected animals. Rectal SIVΔnef infection/vaccination protected 7 out of 7 SIVΔnef-infected macaques from SIVmac239wt rectal infection (vs 12 out of 16 SIVΔnef-negative macaques), while 1 out of 3 animals co-infected with SIVΔnef and HSV-2 acquired SIVmac239wt infection. HSV-2/SIVmac239wt co-infected animals had increased concentrations of inflammatory factors in their plasma and rectal fluids and a tendency toward higher acute SIVmac239wt plasma viral load. However, they had higher blood CD4 counts and reduced depletion of CCR5+ CD4+ T cells compared to SIVmac239wt-only infected animals. Thus, rectal HSV-2 infection generates a pro-inflammatory environment that may increase susceptibility to rectal SIV infection and may impact immunological and virological parameters during acute SIV infection. Studies with larger number of animals are needed to confirm these findings.

    The morphology and development of the digestive tract of insects has been extensively studied, but little attention has been given to the development of the rectal pads. These organs are responsible for absorption of water and salts. In insects where they occur, there are usually six ovoid rectal pads located in the medial-anterior portion of the rectum. The rectal pad has three types of cells: principal, basal, and junctional. The arrangement of these three cell types delimits an intrapapillary lumen. The aim of the current study is to describe the development of the rectal pads during postembryonic development of Melipona quadrifasciata anthidioides and Melipona scutellaris. Specimens were analyzed at the following developmental stages: white-, pink-, brown-, and black-eyed pupae, and adult workers. The development of the rectal pad begins as a thickening of the epithelium in white-eyed pupae at 54 hr. At this stage, there is neither a basal cell layer nor intrapapillary lumen. The basal layers begin to form in the pink-eyed pupa and are completely formed at the end of the development of the brown-eyed pupa. In the brown-eyed pupal stage, the intrapapillary lumen is formed and the junctional cells are positioned and completely differentiated. Necrotic and apoptotic cell death were detected along with cell proliferation in the whole rectum during pupal development, suggesting that the development of the rectal pads involves cell proliferation, death, and differentiation. The rectal pads originate only from the ectoderm.

    Abstract The occurrence of anastomotic leakage (AL) remains a major concern in the early postoperative stage. Because of the relatively high morbidity and mortality of AL in patients with laparoscopic low rectal cancer who receive an anterior resection, a fecal diverting method is usually introduced. The Valtrac™-secured intracolonic bypass (VIB) was used in open rectal resection, and played a role of protecting the anastomotic site. This study was designed to assess the efficacy and safety of the VIB in protecting laparoscopic low rectal anastomosis and to compare the efficacy and complications of VIB with those of loop ileostomy (LI). Medical records of the 43 patients with rectal cancer who underwent elective laparoscopic low anterior resection and received VIB procedure or LI between May 2011 and May 2013 were retrospectively analyzed, including the patients’ demographics, clinical features, and operative data. Twenty-four patients received a VIB and 19 patients a LI procedure. Most of the demographics and clinical features of the groups, including Dukes stages, were similar. However, the median distance of the tumor edge from the anus verge in the VIB group was significantly longer (7.5 cm; inter-quartile range [IQR] 7.0–9.5 cm) than that of the L1 group (6.0 cm; IQR 6.0–7.0 cm). None of the patients developed clinical AL. The comparisons between the LI and the VIB groups were adjusted for the significant differences in the tumor level of the groups. After adjustment, the LI group experienced longer overall postoperative hospital stay (14.0 days, IQR: 12.0, 16.0 days; P < 0.001) and incurred higher costs ($6300 (IQR: $5900, $6600)) than the VIB group (7.0 days, $4800; P < 0.05). Stoma-related complications in the ileostomy group included dermatitis (n = 2), stoma bleeding (n = 1), and wound infection after closure (n = 2). No BAR-related complications occurred. The mean time to Valtrac™ ring loosening was 14.1 ± 3

    Urologic residents need to learn basic and applied knowledge of female pelvic anatomy, a subject rarely taught beyond preclinical undergraduate medical education. This study tests the hypothesis that urologic resident knowledge of female pelvic anatomy and prolapse may be enhanced with a seminar. Twenty residents attended a one day seminar combining didactics and a cadaveric dissection related to female pelvic anatomy and female pelvic prolapse conditions. Resident knowledge was measured with a multiple choice test administered in a pretest-posttest experimental design. Resident attitudes toward the seminar were assessed by a 20 item survey using a strongly disagree to strongly agree scale. Pretest and posttest mean scores were 55% and 71% respectively, p=.0007 (Kuder-Richardson 20 coefficients were 0.7). Questionnaire responses indicated positive opinions regarding the educational value of the seminar. Urologic resident knowledge of female pelvic anatomy and pelvic prolapse conditions may be enhanced by conducting a one day teaching seminar.

  6. Pre-referral rectal artesunate in severe malaria: flawed trial

    2011-01-01

    Background Immediate injectable treatment is essential for severe malaria. Otherwise, the afflicted risk lifelong impairment or death. In rural areas of Africa and Asia, appropriate care is often miles away. In 2009, Melba Gomes and her colleagues published the findings of a randomized, placebo-controlled trial of rectal artesunate for suspected severe malaria in such remote areas. Enrolling nearly 18,000 cases, the aim was to evaluate whether, as patients were in transit to a health facility, a pre-referral artesunate suppository blocked disease progression sufficiently to reduce these risks. The affirmative findings of this, the only trial on the issue thus far, have led the WHO to endorse rectal artesunate as a pre-referral treatment for severe malaria. In the light of its public health importance and because its scientific quality has not been assessed for a systematic review, our paper provides a detailed evaluation of the design, conduct, analysis, reporting, and practical features of this trial. Results We performed a checklist-based and an in-depth evaluation of the trial. The evaluation criteria were based on the CONSORT statement for reporting clinical trials, the clinical trial methodology literature, and practice in malaria research. Our main findings are: The inclusion and exclusion criteria and the sample size justification are not stated. Many clearly ineligible subjects were enrolled. The training of the recruiters does not appear to have been satisfactory. There was excessive between center heterogeneity in design and conduct. Outcome evaluation schedule was not defined, and in practice, became too wide. Large gaps in the collection of key data were evident. Primary endpoints were inconsistently utilized and reported; an overall analysis of the outcomes was not done; analyses of time to event data had major flaws; the stated intent-to-treat analysis excluded a third of the randomized subjects; the design-indicated stratified or multi

    Background: Degenerated disc disease (DDD) is a common disorder responsible for increased morbidity in a productive age group. Its etiology is multifactorial and genetic factors have been predominantly implicated. Disc prolapse results due to tear in the annulus, which is a fibrous structure composed largely of type I collagen. Functional polymorphism at the Sp1 site of the collagen I alpha 1 (COL1A1) gene has shown a positive association with DDD in Dutch and Greek populations. The purpose of this study was to assess COL1A1 Sp1 gene polymorphism in the Indian population. Materials and Methods: Fifty clinically and radiologically proven patients with disc prolapse requiring surgery were included as cases and 50 healthy, age-matched volunteers served as controls. After isolating DNA from their blood sample, genotyping for COL1A1 polymorphism (rs1800012) was performed and identified as GG, GT, and TT. Results: The mean age and body mass index in cases and controls were similar. 76% of the patients were males. The most common site of disc degeneration was L4–L5 (36%), followed by L5–S1 (34%). Homozygous–GG, heterozygous GT, and homozygous TT genotypes were seen in 38 (76%), 10 (20%) and 2 (4%) cases respectively, controls had similar percentage of genotypes as well. The alleles in cases and the control group showed no significant difference (P = 0.6744) and followed the Hardy–Weinberg Equilibrium in the study population. Conclusion: The COL1A1 (rs1800012) is in Hardy–Weinberg equilibrium in the present subset of Indian population. But taken as a single factor, it was not found to be associated with DDD in this preliminary study. Disc degeneration is multifactorial and also anticipated to be a result of multiple genes involvement and gene-gene interaction. PMID:26806964

    AIM: To evaluate the feasibility and safety of endoscopic submucosal dissection (ESD) for lower rectal lesions with hemorrhoids. METHODS: The outcome of ESD for 23 lesions with hemorrhoids (hemorrhoid group) was compared with that of 48 lesions without hemorrhoids extending to the dentate line (non-hemorrhoid group) during the same study period. RESULTS: Median operation times (ranges) in the hemorrhoid and non-hemorrhoid groups were 121 (51-390) and 130 (28-540) min. The en bloc resection rate and the curative resection rate in the hemorrhoid group were 96% and 83%, and they were 100% and 90% in the non-hemorrhoid group, respectively. In terms of adverse events, perforation and postoperative bleeding did not occur in both groups. In terms of the clinical course of hemorrhoids after ESD, the rate of complete recovery of hemorrhoids after ESD in lesions with resection of more than 90% was significantly higher than that in lesions with resection of less than 90%. CONCLUSION: ESD on lower rectal lesions with hemorrhoids could be performed safely, similarly to that on rectal lesions extending to the dentate line without hemorrhoids. In addition, all hemorrhoids after ESD improved to various degrees, depending on the resection range. PMID:27468216

  9. Comparison of tympanic membrane and rectal temperatures of anesthetized fallow deer (Dama dama)

    Paired tympanic membrane and rectal temperatures were compared for 103 female fallow deer (Dama dama) after short-term anesthesia to determine if tympanic temperature was a reliable indicator of hyperthermia associated with handling stress. Each deer was restrained in a drop-floor chute, anesthetized by i.v. injection of xylazine hydrochloride and ketamine hydrochloride, and removed from the chute. After a short procedure was completed, i.m. antibiotics and i.v. yohimbine hydrochloride were given to each deer. Temperature measurements were obtained during recovery from anesthesia, approximately 10 min after initial restraint. Mean tympanic temperature (38.6 degrees C +/- 0.7 degrees C; range 37.4-40.8 degrees C) was significantly lower than mean rectal temperature (40.1 degrees C +/- 0.8 degrees C; range 37.5-42.0 degrees C) [corrected]. One animal had rectal and tympanic temperatures of 42.0 degrees C and 40.8 degrees C, respectively, but regained normal body temperature after cooling measures were applied. Tympanic membrane temperature measurement may provide a method for evaluation of body temperature by separating retained body heat caused by exertion from critical elevations in core body temperature associated with clinical disease or capture stress.

    Fecal impaction is the third cause of lower gastrointestinal tract obstruction after strictures for colon cancer and postoperative adhesions. A rapid diagnosis is necessary to avoid complications due to intestinal obstruction. Rectal phytobezoar due to prickly pear fruit seeds are an extremely rare entity, in the literature about twenty similar cases are described. Prickly pears are common in many countries, even in the Mediterranean area. When the ingestion of their fruit is excessive, this can be harmful, leading to the formation of phytobezoar causing fecal impaction. We describe the first case of phytobezoar due to prickly pear fruit seeds in continental Europe: a 76-year-old Italian female who ingested almost 40 prickly pear fruit leading to the composition of a large rectal phytobezoar. The patient presented clinically with fecal impaction, diagnosed by imaging and successfully treated by rectal irrigation and manual disimpaction. Our aim is to remind the physicians of these risks in evaluating patients with intestinal obstruction, when there is positive anamnesis for provenience from some areas in which these fruits are eaten. We also want to underline the role of Imaging Multi Detector Computed Tomography (MDCT) in the diagnosis of these very uncommon entities.

    The available dose/volume/outcome data for rectal injury were reviewed. The volume of rectum receiving >=60Gy is consistently associated with the risk of Grade >=2 rectal toxicity or rectal bleeding. Parameters for the Lyman-Kutcher-Burman normal tissue complication probability model from four clinical series are remarkably consistent, suggesting that high doses are predominant in determining the risk of toxicity. The best overall estimates (95% confidence interval) of the Lyman-Kutcher-Burman model parameters are n = 0.09 (0.04-0.14); m = 0.13 (0.10-0.17); and TD{sub 50} = 76.9 (73.7-80.1) Gy. Most of the models of late radiation toxicity come from three-dimensional conformal radiotherapy dose-escalation studies of early-stage prostate cancer. It is possible that intensity-modulated radiotherapy or proton beam dose distributions require modification of these models because of the inherent differences in low and intermediate dose distributions.

    Purpose: PRL-3 (phosphatase of regenerating liver) is involved in metastasis of colorectal cancer; however, its therapeutic implication in cancer patients has not been studied. We investigated the relationships of PRL expression to radiotherapy (RT) in rectal cancer patients. Methods and Materials: Phosphatase of regenerating liver expression was immunohistochemically examined in distant (n = 36) and adjacent (n = 82) normal mucosa, primary tumor (n = 125), biopsy specimens (n = 96), and lymph node metastasis (n = 30) from rectal cancer patients participating in a clinical trial of preoperative RT. Results: Phosphatase of regenerating liver expression was increased from the distant to adjacent mucosa and to the primary tumor (p < 0.05). PRL was highly expressed at the invasive margin in 28% of the primary tumors and 26% of the metastases. In the RT group, strong PRL expression at the invasive margin was related to distant recurrence (p 0.006) and poor survival (p = 0.01), but not in the non-RT group. The survival significance remained even after adjusting for Dukes' stage and differentiation (p = 0.02). Additional multivariate analyses showed that the correlation with prognostic significance of PRL differed between the RT and non-RT groups (p = 0.01). Conclusion: Phosphatase of regenerating liver expression (rather than PRL-3 alone) at the invasive margin predicted resistance to RT and unfavorable survival in rectal cancer patients with preoperative RT.

    Purpose: To investigate p73 expression in normal mucosa, primary tumor, and metastasis in relation to radiotherapy (RT) response and clinicopathologic/biologic variables in rectal cancers. Methods and Materials: p73 was immunohistochemically examined on biopsies (unirradiated, n = 102), distant (from the large bowel, n = 82), and adjacent (adjacent to primary tumor, n = 89) normal mucosa samples, primary tumors (n = 131), and lymph node metastasis (n = 32) from rectal cancer patients participating in a clinical trial of preoperative RT. Seventy-four patients received surgery alone and 57 received additional RT. Results: Cytoplasmic p73 was increased in the primary tumor compared with the distant or adjacent mucosa (p {<=} 0.0001). Nuclear (p = 0.02) and cytoplasmic (p = 0.003) p73 was higher in irradiated distant mucosa samples than in unirradiated ones, and nuclear p73 tended to be increased in irradiated primary tumors compared with unirradiated ones (p = 0.06). p73 was positively related to cyclooxygenase-2 expression in irradiated tumors (p = 0.03). p73-negative tumors tended to have a lower local recurrence after RT compared with unirradiated cases (p 0.06). Conclusions: Normal epithelial cells seem more sensitive to RT than tumor cells regarding p73 expression. Patients with p73-negative rectal tumors may have a lower risk of local recurrence after RT.

    This study sought to assess the value of two-dimensional (2D) transthoracic echocardiography (TTE), 2D xPlane imaging and three-dimensional (3D) TTE for the definition of the site and the extent of mitral valve (MV) prolapse. Fifty patients underwent transthoracic 2D, 2D xPlane and 3D echocardiography. With 2D xPlane a segmental analysis of the MV was performed, by making a lateral sweep across the MV coaptation line as seen in the parasternal short-axis view. Inter-observer agreement for specific scallop prolapse was for 2D xPlane excellent (97%, kappa = 0.94) and for 3D TTE moderate (85%, kappa = 0.67). The respective sensitivities of standard 2D TTE, 2D xPlane, and 3D TTE for the identification of the precise posterior scallop prolapse were for P1 92, 85, and 92%, for P2 96, 96, and 82%, and for P3 86, 81, and 71%. In total, 5 (8%) prolapsing MV scallops were missed by 2D TTE, 7 (12%) by 2D xPlane, and 12 (20%) by 3D TTE. The sensitivity of 3D TTE was significantly lower than standard 2D imaging (80% versus 93%, P < 0.05). The extent of P2 prolapse was under or overestimated in 5 patients with 2D xPlane and in 9 patients with 3D TTE. 2D xPlane imaging is an accurate, easy to use (compared to 3D TTE) and easy to interpret (compared to 2D and 3D TTE) imaging modality to study the site and the extent of MV prolapse.

    Purpose: The purpose of the study was the qualitative and quantitative evaluation of acute radiation-induced rectal changes in patients who underwent preoperative radiotherapy according to two different irradiation protocols. Patients and Methods: Sixty-eight patients with rectal adenocarcinoma underwent preoperative radiotherapy; 44 and 24 patients underwent hyperfractionated and hypofractionated protocol, respectively. Fifteen patients treated with surgery alone served as a control group. Five basic histopathologic features (meganucleosis, inflammatory infiltrations, eosinophils, mucus secretion, and erosions) and two additional features (mitotic figures and architectural glandular abnormalities) of radiation-induced changes were qualified and quantified. Results: Acute radiation-induced reactions were found in 66 patients. The most common were eosinophilic and plasma-cell inflammatory infiltrations (65 patients), erosions, and decreased mucus secretion (54 patients). Meganucleosis and mitotic figures were more common in patients who underwent hyperfractionated radiotherapy. The least common were the glandular architectural distortions, especially in patients treated with hypofractionated radiotherapy. Statistically significant differences in morphologic parameters studied between groups treated with different irradiation protocols were found. Conclusion: The system of assessment is a valuable tool in the evaluation of radiation-induced changes in the rectal mucosa. A greater intensity of regenerative changes was found in patients treated with hyperfractionated radiotherapy.

    Nowadays, the de nition of patient-speci c constraints in prostate cancer radiotherapy planning are solely based on dose-volume histogram (DVH) parameters. Nevertheless those DVH models lack of spatial accuracy since they do not use the complete 3D information of the dose distribution. The goal of the study was to propose an automatic work ow to de ne patient-speci c rectal sub-regions (RSR) involved in rectal bleeding (RB) in case of prostate cancer radiotherapy. A multi-atlas database spanning the large rectal shape variability was built from a population of 116 individuals. Non-rigid registration followed by voxel-wise statistical analysis on those templates allowed nding RSR likely correlated with RB (from a learning cohort of 63 patients). To de ne patient-speci c RSR, weighted atlas-based segmentation with a vote was then applied to 30 test patients. Results show the potentiality of the method to be used for patient-speci c planning of intensity modulated radiotherapy (IMRT).

    Rectal examination and fecal disimpaction are common procedures performed in the Emergency Department on a daily basis. Here, we report a rare case of a patient suffering a cardiac arrest and ultimately death likely due to rectal manipulation. A 66-year-old male presented to the Emergency Department (ED) with a complaint of abdominal distention and constipation. A rectal exam was performed. During the examination the patient became apneic. On the cardiac monitor the patient was found to be in pulseless electrical activity with a bradycardic rate. Our recommendation would be to provide adequate analgesia and close patient monitoring of those undergoing this procedure especially patients with significant stool burdens. PMID:28116179

    2011-01-01

    Fournier gangrene is a necrotizing fasciitis of the genital and perineal region. Diverse factors predispose to Fournier gangrene, such as diabetes mellitus, ethylism, liver dysfunction, haematological disorders, obesity or recent regional instrumentation. Rectal tumours can also predispose to Fournier gangrene; most of the reported cases are perforated or unresectable colorectal tumours, but some cases of anorectal cancer diagnosed after recovery from Fournier gangrene have also been reported. In these cases, the presence of a rectal tumour at the time of, or prior to, diagnosis of Fournier gangrene could not be ruled out. We present three cases of rectal cancer whose first manifestation was as Fournier gangrene.

    1975-01-01

    An typical nuclear structure consisting of a cribriform and condensed chromatin pattern with hyperchromasia, a small nucleolus and a moderately increased nuclear-cytoplasmic ratio was observed in the epithelial cells of the crypts and in the stromal and muscular cells of 51 out of 70 oncologically negative biopsies of the rectal mucosa. The subsequent retrieval of all clinical and histologia data revealed that the 51 cases included 39 of adenocarcinoma of the large intestine either present (15 cases) at a variable distance from the false negative biopsy or removed previously (24 cases), 7 of extra-intestinal malignant tumor (parotid gland, urinary bladder, endometrium, breast, stomach, metastatic, anus) and 5 with benign conditions of the large intestine. Of the remaining 19 cases whose biopsies did not reveal the atypical nuclear structure 16 had benign lesions of the large intestine and nowhere evidence of malignancy, two had an adenocarcinoma of the large bowel (one present and one removed previously) and one a carcinoma of the anus. In the rectal biopsies examined the atypical nuclear structure was detected in 93.9% of the cases with a malignant tumor either present or removed previously and in 19% of the cases with benign conditions. The morphologic evidence indicated that the atypical nuclear structure was compatible with a possible distrubance of the mitotic cycle since the findings were restricted to the generative compartment of rectal epithelium. The results are discussed in connection with their possible practical use as a diagnostic aid in the evaluation and interpretation of false negative and negative rectal biopsies as well as with their possible significance in the biology of tumor-bearing hosts.

    Background: Patients with locally advanced rectal cancer are treated with preoperative chemoradiotherapy followed by surgical resection. Despite similar clinical parameters (uT2-3, uN+) and standard therapy, patients’ prognoses differ widely. A possible prediction of prognosis through microRNAs as biomarkers out of treatment-naïve biopsies would allow individualized therapy options. Methods: Microarray analysis of 45 microdissected preoperative biopsies from patients with rectal cancer was performed to identify potential microRNAs to predict overall survival, disease-free survival, cancer-specific survival, distant-metastasis-free survival, tumor regression grade, or nodal stage. Quantitative real-time polymerase chain reaction (qPCR) was performed on an independent set of 147 rectal cancer patients to validate relevant miRNAs. Results: In the microarray screen, 14 microRNAs were significantly correlated to overall survival. Five microRNAs were included from previous work. Finally, 19 miRNAs were evaluated by qPCR. miR-515-5p, miR-573, miR-579 and miR-802 demonstrated significant correlation with overall survival and cancer-specific survival (p < 0.05). miR-573 was also significantly correlated with the tumor regression grade after preoperative chemoradiotherapy. miR-133b showed a significant correlation with distant-metastasis-free survival. miR-146b expression levels showed a significant correlation with nodal stage. Conclusion: Specific microRNAs can be used as biomarkers to predict prognosis of patients with rectal cancer and possibly stratify patients’ therapy if validated in a prospective study.

    2008-07-01

    Urinary incontinence (UI) is defined as uncontrolled urine leakage through an urethra. At present, the following types of UI can be specified: stress incontinence (SI), urge incontinence (UI), mixed incontinence (MI), overflow incontinence (OI) in which the bladder becomes too full because it cannot be fully emptied, and functional incontinence (FI). Incontinence is one of the most common chronic diseases in women and is found in 17-60% of the whole population. In most patients, SI is combined with pelvic organ prolapse. The basic risk factors mentioned as contributing to these two conditions are obstetrical past and gynaecological history and atrophic changes in the urogenital area. There are also a number of diseases related to the increase in intra-abdominal pressure, such as obesity chronic constipation and diseases associated with persistent cough. Other factors leading to pelvic organ prolapse include hard physical work, some professional sports, connective tissue disorders, neuropathy and disturbed innervation of the pelvic floor. To deal with stress incontinence (SI), conservative and surgical treatment is employed. In the first degree intensity, it is mainly physiotherapy, electrical stimulation of the pelvic floor muscles, lifestyle modification and reduction of body mass. When the SI symptoms are more severe, surgical treatment is usually preferred. From among many methods, these presently used are Burch and sling operations. On the other hand, surgical treatment for pelvic organ prolapse involves colpoperineoplasty with the use of polypropylene mesh (Prolift), colporrhaphy by double TOT approach method, median colporrhaphy, Cooper's ligament or sacrospinous ligament colpopexy, and attachment of the uterus to the sacrum. The results of surgical treatment depend on co-occurrence of risk factors, the surgical method chosen, the lapse of time from the surgery and the type of the applied biomedical material.

    The aim of this study was to develop the short form of a condition-specific, reliable, validated and self-administered instrument to evaluate sexual function in women with pelvic organ prolapse and/or urinary incontinence. The Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire -12 (PISQ-12) was developed from the data of 99 of 182 women surveyed to create the long form (PISQ-31). An additional 46 patients were recruited for further validation. All subsets regression analysis identified 12 items likely to predict PISQ-31 scores. Short form scores underwent correlation analysis with long form, Incontinence Impact Questionnaire - 7 (IIQ-7), Sexual History Form -12 (SHF-12) and Symptom Questionnaire (SQ) scores. Test-retest reliability was checked with a subset of 20 patients. All subsets regression analysis with R>0.92 identified 12 items that predicted PISQ-31 scores. Short form scores were highly correlated with long form scores ( R=0.75-0.95). Correlations of the PISQ-12 with SHF-12 ( R=-0.66 and -0.68) and IIQ-7 ( R=-0.38 and -0.54) scores were similar to correlation of the PISQ-31 with these other measures. Reliability was moderate to high, with weighted kappa values from 0.56 to 0.93. PISQ-12 scores were lower in patients with low sexual function as measured on the SHF-12 ( P <0.001), and lower in women with depression as measured on the SQ ( P <0.001). The PISQ-12 is a validated and reliable short form that evaluates sexual function in women with urinary incontinence and/or pelvic organ prolapse and predicts PISQ-31 scores. It is able to distinguish women with poor sexual function as measured on the SHF-12.

    Sparing of sensation in sacral dermatomes and of sphincter control was found in eight out of fourteen cases of severe cauda equina compression from massive central lumbar disc prolapse. Although the triangular shape of the lumbar spinal canal may be one factor for this it was found from a necropsy model that the increase in linear strain on the stretched roots of the cauda equina is least in the more centrally placed lower sacral roots. It is argued that the lower tension in these roots is determined by Young's Modulus. PMID:4009195

    C3-4 cervical disc prolapse was associated with basilar invagination and short neck in a 21-year-old man and additionally with an extensive Klippel-Feil abnormality and fusion of multiple cervical vertebrae in a 32-year-old man. The transoral surgical route was adopted for cervical discectomy in the latter case and an additional odontoidectomy in the former case. Interbody plate and screw fixation was carried out in the patient with Klippel-Feil abnormality. Both the patients were relieved of symptoms and remained asymptomatic at follow up. Simultaneous fixation procedure is not mandatory after transoral surgery in patients with basilar invagination.

    Background Few studies have examined fetal, infant and maternal mortality and morbidity among pregnant women at very early gestation with an open cervix and prolapsed membranes. We carried out a study describing the outcomes of women hospitalized with prolapsed membranes at 22–28 weeks’ gestation. Methods We prospectively recruited women with singleton pregnancies admitted at 22–28 weeks’ gestation to tertiary hospitals of the Canadian Perinatal Network between 2005 and 2009. Time-to-delivery, perinatal death, neonatal intensive care unit (NICU) admission, severe neonatal morbidity and severe maternal morbidity were compared between women admitted at 22–25 vs. 26–28 weeks gestation. Logistic regression was used to estimate adjusted odds ratios (AOR) and 95% confidence intervals. Results 129 women at 22–25 weeks gestation and 65 women at 26–28 weeks gestation were admitted to hospital and the median time-to-delivery was 4 days in both groups. Stillbirth rates were 12.4% vs 4.6% among women admitted at earlier vs later gestation (AOR 2.8, 95% CI 0.5–14.8), while perinatal death rates were 38.0% vs 6.1% (AOR 14.1, 95% CI 3.5–59.0), respectively. There were no significant differences in NICU admission and severe morbidity among live-born infants; 89.4% and 82.3% died or were admitted to NICU, (P value 0.18), and 53.9% vs 44.0% of NICU infants had severe neonatal morbidity (P value 0.28). Antibiotics, tocolysis and cerclage did not have a significant effect on perinatal death. Maternal death or severe maternal morbidity occurred in 8.5% and 6.2% of women admitted at 22–25 vs 26–28 weeks (AOR 1.2, 95% CI 0.4–4.2). Conclusion Perinatal mortality among women with prolapsed membranes at very early gestation is high, although significantly lower among those admitted at a relatively later gestational age. Rates of adverse maternal outcomes are also high. This information can be used to counsel women with prolapsed membranes at 22 to 28 weeks

    AIM To clarify which factors may influence pathological tumor response and affect clinical outcomes in patients with locally advanced rectal carcinoma treated with neo-adjuvant chemoradiotherapy and surgery. METHODS Tumor regression grade (TRG) according to the Dworak system and yTNM stage were assessed and correlated with pre-treatment clinico-pathological variables in 215 clinically locally advanced (cTNM stage II and III) rectal carcinomas. Prognostic value of all pathological and clinical factors on disease free survival (DFS) and cancer specific survival (CSS) was analyzed by Kaplan Meier and Cox-regression analyses. RESULTS cN+ status, mucinous histotype or poor differentiation in the pre-treatment biopsy were significantly associated with lower pathological response (low Dworak grade and TNM remaining unchanged/upstaging). Cases showing acellular mucin pools in surgical specimens all had unremarkable clinical courses with no deaths or recurrences during follow-up. Dworak grade had prognostic significance for DFS and CSS. However, compared to the 5-tiered system, a simplified two-tiered grading system, in which grades 0, 1 and 2 were grouped as absent/partial regression and grades 3 and 4 were grouped as total/subtotal regression, was more reproducible and prognostically informative. The two-tiered Dworak system, yN stage, craniocaudal extension of the tumor and radial margin status were significant independent prognostic variables. CONCLUSION Our data suggest that caution should be applied in using a conservative approach in rectal carcinomas with cN+ status, extensive/lower involvement of the rectum and mucinous histotype or poor differentiation. Although Dworak TRG is prognostically significant, a simplified two-tiered system could be preferable. Finally, cases with acellular mucin pools should be carefully evaluated to definitely exclude residual mucinous carcinoma. PMID:28293088

    Objective Currently the choice of chemotherapy regimen in rectal cancer is made prior to surgery in contrast to colon cancer where it is made postoperatively after the pathological stage has been determined. If we could identify which are the important pretreatment prognostic factors in rectal cancer, we could then target those patients with unfavorable features to investigate potentially more effective preoperative chemotherapy regimens aimed at those with unfavorable features. The present study aims to determine pre-treatment prognostic factors that are associated with an unfavorable outcome. Methods A retrospective review of 99 rectal cancer patients operated at the Hospital Auxilio Mutuo and Hospital San Pablo was done. Sociodemographic characteristics, clinical and treatment data was collected. Results 54% were males. The mean ± sd age was 62.2 ± 10.4. In age-adjusted Cox model, male gender [HR (95%CI): 3.32 (1.09–10.13)], mucinous carcinoma [HR (95%CI): 3.67 (1.25–10.77)], and clinical stages II & III [HR (95%CI): 8.19 (1.08–62.08)] were predictors of poor prognosis. In multivariate age-adjusted analysis, a tendency towards a poorer prognosis was observed for male patients [HR: 2.60] CEA level ≥ 5ng/ml [HR: 2.55], mucinous carcinoma [HR:2.96], and clinical stages II & III [HR:4.96], although results were not statistically significant (p>0.05), Conclusion Although current therapeutic results are relatively favorable with preoperative 5-Fluorouracil (5FU) and radiotherapy, future clinical trials should address the management of those cases with adverse pretreatment prognostic factors so that they can be treated with potentially more effective albeit more toxic chemotherapy regimens.

    Purpose Robotic surgery is expected to have advantages over laparoscopic surgery; however, there are limited data regarding the feasibility of robotic surgery for rectal cancer after preoperative chemoradiotherapy (CRT). Therefore, we evaluated the short-term outcomes of robotic surgery for rectal cancer. Materials and Methods Thirty-three patients with cT3N0-2 rectal cancer after preoperative CRT who underwent robotic low anterior resection (R-LAR) between March 2010 and January 2012 were matched with 66 patients undergoing laparoscopic low anterior resection (L-LAR). Perioperative clinical outcomes and pathological data were compared between the two groups. Results Patient characteristics did not differ significantly different between groups. The mean operation time was 441 minutes (R-LAR) versus 277 minutes (L-LAR, p < 0.001). The open conversion rate was 6.1% in the R-LAR group and 0% in the L-LAR group (p=0.11). There were no significant differences in the time to flatus passage, length of hospital stay, and postoperative morbidity. In pathological review, the mean number of harvested lymph nodes was 22.3 in R-LAR and 21.6 in L-LAR (p=0.82). Involvement of circumferential resection margin was positive in 16.1% and 6.7%, respectively (p=0.42). Total mesorectal excision (TME) quality was complete in 97.0% in R-LAR and 91.0% in L-LAR (p=0.41). Conclusion In our study, short-term outcomes of robotic surgery for rectal cancer after CRT were similar to those of laparoscopic surgery in respect to bowel function recovery, morbidity, and TME quality. Well-designed clinical trials are needed to evaluate the functional results and long-term outcomes of robotic surgery for rectal cancer. PMID:25779367

    Over the past couple of decades, multimodality treatment for the management of resectable rectal cancer has substantially improved the outcome of affected patients. However, the broad and unpredictable response to tumor of patients with rectal cancer treated with preoperative chemoradiotherapeutic interventions shows that our understanding of the molecular events leading to radioresistance in patients affected with this malignancy remains sparse. Multiple attempts by individual molecular markers in gene array and tissue microarray studies have emerged with the goal of identifying predictors of a response to chemoradiation in patients with rectal cancer. In this report, we discuss the status of the markers currently available in an attempt to tailor specific targeted therapies for rectal cancer in the neoadjuvant setting.

    Neoadjuvant (preoperative) chemoradiotherapy (CRT) decreases the risk of rectal cancer recurrence and reduces tumour volume prior to surgery. However, response to CRT varies considerably between individuals and factors associated with response are poorly understood. Foxp3+ regulatory T cells (Tregs) inhibit anti-tumour immunity and may limit any response to chemotherapy and radiotherapy. We have previously reported that a low density of Tregs in the tumour stroma following neoadjuvant CRT for rectal cancer is associated with improved tumour regression. Here we have examined the association between Treg density in pre-treatment diagnostic biopsy specimens and treatment response, in this same patient cohort. We aimed to determine whether pre-treatment tumour-infiltrating Treg density predicts subsequent response to neoadjuvant CRT. Foxp3+, CD8+ and CD3+ cell densities in biopsy samples from 106 patients were assessed by standard immunohistochemistry (IHC) and evaluated for their association with tumour regression grade and survival. We found no association between the density of any T cell subset pre-treatment and clinical outcome, indicating that tumour-infiltrating Treg density does not predict response to neoadjuvant CRT in rectal cancer. Taken together with the findings of the previous study, these data suggest that in the context of neoadjuvant CRT for rectal cancer, the impact of chemotherapy and/or radiotherapy on anti-tumour immunity may be more important than the state of the pre-existing local immune response.

    Background. Children aged <5 years were enrolled in a large study in 3 countries of sub-Saharan Africa because they had danger signs preventing them from being able to take oral medications. We examined compliance and factors associated with compliance with referral advice for those who were treated with rectal artesunate. Methods. Patient demographic data, speed of accessing treatment after danger signs were recognized, clinical symptoms, malaria microscopy, treatment-seeking behavior, and compliance with referral advice were obtained from case record forms of 179 children treated with prereferral rectal artesunate in a multicountry study. We held focus group discussions and key informant interviews with parents, community health workers (CHWs), and facility staff to understand the factors that deterred or facilitated compliance with referral advice. Results. There was a very high level of compliance (90%) among patients treated with prereferral rectal artesunate. Age, symptoms at baseline (prostration, impaired consciousness, convulsions, coma), and malaria status were not related to referral compliance in the analysis. Conclusions. Teaching CHWs to diagnose and treat young children with prereferral rectal artesunate is feasible in remote communities of Africa, and high compliance with referral advice can be achieved.

    Background & Aims This study is designed to investigate the expression of survivin and p53 in human rectal cancer tissues and analyze associations between expression and clinical outcomes in terms of disease recurrence and survival duration. Results During follow-up (median 119.0, range 6.6 to 161.3 months), tumor recurrence was detected in 50 patients (43.1%), and local recurrence developed as a first failure site in 13 patients (11.2%). Positive immunostaining of nuclear and cytoplasmic survivin was observed in about one quarter of patients, and about half of all patients had positive staining for p53. Both survivin and p53 were significant prognostic factors of disease-free survival in the univariate analyses, but only survivin remained a significant prognostic factor in the multivariate analysis. Methods We performed a retrospective study with 116 locally advanced rectal cancer patients who underwent total mesorectal excision (TME) followed by postoperative concurrent chemo-radiation therapy (CCRT). Immunohistochemical staining was conducted using antibodies for survivin or p53, and their expression was analyzed using an individual score that combined the percentage of positive cells and staining intensity. Conclusions Overexpression of nuclear and cytoplasmic survivin in locally advanced rectal cancer patients was associated with a higher recurrence rate in rectal cancer patients treated with TME followed by postoperative CCRT.

    Rectal seed bezoars are an uncommon cause of fecal impaction, particularly in the United States. Although the literature has reported several cases of phytobezoars composed of various types of seeds, bezoars formed of pumpkin seeds have rarely been reported. We report a case of a man, aged 62 years, with a rectal bezoar composed of pumpkin seeds with complications necessitating extensive treatment, including manual disimpaction and colonoscopy.

    Purpose: To develop a patient-specific rectal toxicity predictor guided plan quality control tool for prostate SBRT plans. Methods: For prostate SBRT cases, four segments of rectal walls including peri-prostatic anterior rectal wall, peri-prostatic lateral rectal walls, peri-prostatic posterior rectal wall and rectum superior to prostate are identified as organs at risk and the circumference of rectal wall receiving more than 39 Gy (CRW39) and 24 Gy (CRW24) are rectal toxicity predictors. In this new geometry-dosimetry model, a patient geometry descriptor, differential circumference of rectal wall (dCRW) is used as model input geometry parameters and plan dosimetric endpoints CRW39 and CRW24 are output dosimetric parameters. Linear models are built to correlate dCRW to both CRW39 and CRW24 and established with both a linear regression method and a modified bagging ensemble machine learning method. 27 SBRT prostate cases are retrospectively studied from a dose-escalated clinical trial research. 20 prescribed 50 Gy SBRT cases are recruited to train the model and the other rescaled 7 cases are used to evaluated model feasibility and accuracy. Results: Each solved linear coefficient sequence related to CRW39 or CRW24 is a one-dimensional decreasing function of the distance from the PTV boundary, indicating that the different locations of each rectal circumference have different contributions to each particular dosimetric endpoint. The fitting errors for those trained 20 prostate SBRT cases are small with mean values of 2.39%, 2.45% relative to the endpoint values for SBRT rectal toxicity predictor CRW39 and CRW24 respectively. 1 out of 7 evaluation plans is identified as poor quality plan. After re-planning, the CRW39 and CRW24 can be reduced by 3.34% and 3%, without sacrificing PTV coverage. Conclusion: The proposed patient geometry-plan toxicity predictor model for SBRT plans can be successfully applied to plan quality control for prostate SBRT cases.

    Marine elasmobranch rectal gland is a specialized, osmoregulatory organ composed of numerous blind-ended, branched tubules emptying into a central duct. To date, NaCl excretion has been its only described function. Here we use isolated rectal gland tubule fragments from dogfish shark (Squalus acanthias), fluorescent xenobiotics, and confocal microscopy to describe a second function, xenobiotic excretion. Isolated rectal gland tubules rapidly transported the fluorescent organic anion sulforhodamine 101 from bath to lumen. Luminal accumulation was concentrative, saturable, and inhibited by cyclosporin A (CSA), chlorodinitrobenzene, leukotriene C4, and KCN. Inhibitors of renal organic anion transport (probenecid, p-aminohippurate), organic cation transport (tetraethylammonium and verapamil), and P-glycoprotein (verapamil) were without effect. Cellular accumulation of sulforhodamine 101 was not concentrative, saturable, or inhibitable. Rectal gland tubules did not secrete fluorescein, daunomycin, or a fluorescent CSA derivative. Finally, frozen rectal gland sections stained with an antibody to a hepatic canalicular multispecific organic anion transporter (cMOAT or MRP2) showed heavy and specific staining on the luminal membrane of the epithelial cells. We conclude that rectal gland is capable of active and specific excretion of xenobiotics and that such transport is mediated by a shark analog of MRP2, an ATP-driven xenobiotic transporter, but not by P-glycoprotein.

    Introduction This study reports one year outcomes in women who underwent transvaginal pelvic organ prolapse (POP) surgery with Prolift® transvaginal mesh. Methods Pre and post-operative objective vaginal (Pelvic Organ Prolapse Quantification, POP-Q) and subjective symptom and impact assessments (Pelvic Floor Distress Inventory-20, PFDI-20; Pelvic Floor Impact Questionnaire-7, PFIQ-7, respectively) were performed. Post- operative vaginal tenderness, stricture and patient satisfaction were also obtained. Paired t-tests were utilized for analysis. Results Mean age was 61.8±9.8 years; mean follow-up interval was 425.0±80.0 days (range: 237–717). POP-Q measurements of Ba, Bp, and C were significantly improved (all p-values <0.001). PFDI and PFIQ subscales scores significantly improved (all p-values ≤0.004). Thirty-five of 48 (73%) were completely satisfied, 2 (4%) were not satisfied. Complications [n(%)] included graft exposure [1(2%)], dyspareunia [2(4%)], and granulation tissue [3(6%)]. Conclusions Women undergoing transvaginal repair of POP with the Prolift® mesh system showed significant improvement in one-year anatomic and subjective measures. PMID:19714287

    Objectives/Introduction To report the initial anatomic, radiographic, and genetic evaluations of a novel form of spontaneous pelvic organ prolapse (S-POP) in mice. Methods We observed S-POP in a colony of UPII-SV40T transgenic mice developed for studies on bladder cancer. We utilized magnetic resonance imaging and necropsy to characterize this finding. We have established a breeding colony to identify inheritance patterns and for future studies. Results Selective breeding isolated the S-POP phenotype from the transgene. In contrast to other animal models, the S-POP mouse does not require an obligatory antecedent event to manifest pelvic organ prolapse. Necropsy and imaging demonstrate significant displacement of the pelvic organs distal to the pelvic floor in both sexes. The appearance of the POP is similar to that seen in the human female phenotype. Preliminary breeding studies indicate an autosomal dominant inheritance pattern. Conclusions This mouse may be an effective animal model for the study of POP in humans. PMID:18802654

    The objective of this study was to evaluate the morphological and immunohistochemical alterations of tissue removed from the upper third of anterior vaginal wall in a sample group of the female population presenting homogenous risk factors associated with pelvic organ prolapse (POP). The case study consisted of 14 patients with POP and there were 10 patients in the control group. Patient selection was carried on the basis of specific criteria and all of the patients involved in the study presented one or more of the recognized POP risk factors. Samples were taken from POP patients during vaginal plastic surgery following colpohysterectomy, and from control patients during closure of the posterior fornix following hysterectomy. Samples were processed for histological and immunohistochemical analyses for Collagen I and Collagen III, α-Smooth Muscle Actin (α-SMA), Platelet-Derived-Growth-Factor (PDGF), matrix metalloproteinase 3 (MMP3), tissue inhibitors metalloproteinase 1 (TIMP1), Caspase3. Immunofluorescence analyses for Collagen I and III and PDGF were also carried out. In prolapsed specimens our results show a disorganization of smooth muscle cells that appeared to have been displaced by an increased collagen III deposition resulting in rearrangement of the muscularis propria architecture. These findings suggest that the increase in the expression of collagen fibers in muscularis could probably be due to a phenotypic switch resulting in the dedifferentiation of smooth muscle cells into myofibroblasts. These alterations could be responsible for the compromising of the dynamic functionality of the pelvic floor. PMID:26972719

    The sexual function of women with and without urinary incontinence and/or pelvic organ prolapse (UI/POP) was compared using a condition-specific validated questionnaire, the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ). Eighty-three women with UI/POP and 56 without agreed to participate. PISQ scores were significantly lower among women with UI/POP than in those without (P = 0.003). No differences in the stages of sexual excitement were noted between groups. The frequency of intercourse was less with UI/POP than without (P= 0.04). Women with UI/POP restricted sexual activity for fear of losing urine more frequently than did those without (P = 0.005). No differences were reported in patients' or partners' sexual satisfaction. This study found that women with UI/POP have poorer sexual functioning than those without, as measured by the PISQ, and report less frequent sexual activity. In addition, women with UI/POP are more likely to restrict sexual activity for fear of incontinence, although they report similar levels of satisfaction with their sexual relationships as do women without UI/POP.

  2. Biomechanical evaluation of the pathophysiologic developmental mechanisms of mitral valve prolapse: effect of valvular morphologic alteration.

    Mitral valve prolapse (MVP) refers to an excessive billowing of the mitral valve (MV) leaflets across the mitral annular plane into the left atrium during the systolic portion of the cardiac cycle. The underlying mechanisms for the development of MVP and mitral regurgitation in association with MV tissue remodeling are still unclear. We performed computational MV simulations to investigate the pathophysiologic developmental mechanisms of MVP. A parametric MV geometry model was utilized for this study. Posterior leaflet enlargement and posterior chordal elongation models were created by adjusting the geometry of the posterior leaflet and chordae, respectively. Dynamic finite element simulations of MV function were performed over the complete cardiac cycle. Computational simulations demonstrated that enlarging posterior leaflet area increased large stress concentration in the posterior leaflets and chordae, and posterior chordal elongation decreased leaflet coaptation. When MVP was accompanied by both posterior leaflet enlargement and chordal elongation simultaneously, the posterior leaflet was exposed to extremely large prolapse with a substantial lack of leaflet coaptation. These data indicate that MVP development is closely related to tissue alterations of the leaflets and chordae. This biomechanical evaluation strategy can help us better understand the pathophysiologic developmental mechanisms of MVP.

    OBJECTIVE: To evaluate left ventricular function in young adults with mitral valve prolapse (MVP) without significant mitral regurgitation using two-dimensional strain imaging. METHODS AND RESULTS: A total of 58 asymptomatic young subjects (mean [± SD] age 19.7±1.6 years; 72% male) with MVP were compared with 60 sex- and age-matched healthy subjects. MVP was diagnosed by billowing one or both mitral leaflets >2 mm above the mitral annulus in the long-axis parasternal view. Longitudinal, radial and circumferential strain and strain rate were determined using speckle tracking with a grey-scale frame rate of 50 fps to 85 fps. There were no significant differences in the global systolic left ventricular function of the subjects with MVP compared with the control group. In the MVP group, most of the global myocardial systolic deformation indexes were not reduced. Only the global circumferential strain showed a decrease in the prolapse subjects. Regional, longitudinal, circumferential and radial strain and strain rate were decreased only in septal segments. A decrease in the rotation of the same septal segments at the basal level was also observed. CONCLUSION: Regional septal myocardial deformation indexes decrease in subjects with MVP. These changes may be the first sign indicating the deterioration of left ventricular systolic function as well as the existence of primary cardiomyopathy in asymptomatic young subjects with MVP.

  4. Neoadjuvant chemotherapy prior to preoperative chemoradiation or radiation in rectal cancer: should we be more cautious?

    Neoadjuvant chemotherapy (NACT) is a term originally used to describe the administration of chemotherapy preoperatively before surgery. The original rationale for administering NACT or so-called induction chemotherapy to shrink or downstage a locally advanced tumour, and thereby facilitate more effective local treatment with surgery or radiotherapy, has been extended with the introduction of more effective combinations of chemotherapy to include reducing the risks of metastatic disease. It seems logical that survival could be lengthened, or organ preservation rates increased in resectable tumours by NACT. In rectal cancer NACT is being increasingly used in locally advanced and nonmetastatic unresectable tumours. Randomised studies in advanced colorectal cancer show high response rates to combination cytotoxic therapy. This evidence of efficacy coupled with the introduction of novel molecular targeted therapies (such as Bevacizumab and Cetuximab), and long waiting times for radiotherapy have rekindled an interest in delivering NACT in locally advanced rectal cancer. In contrast, this enthusiasm is currently waning in other sites such as head and neck and nasopharynx cancer where traditionally NACT has been used. So, is NACT in rectal cancer a real advance or just history repeating itself? In this review, we aimed to explore the advantages and disadvantages of the separate approaches of neoadjuvant, concurrent and consolidation chemotherapy in locally advanced rectal cancer, drawing on theoretical principles, preclinical studies and clinical experience both in rectal cancer and other disease sites. Neoadjuvant chemotherapy may improve outcome in terms of disease-free or overall survival in selected groups in some disease sites, but this strategy has not been shown to be associated with better outcomes than postoperative adjuvant chemotherapy. In particular, there is insufficient data in rectal cancer. The evidence for benefit is strongest when NACT is administered

    Connective tissue, consisting mainly of collagen and structural glycoproteins, is an important part of the supportive structures of the genitourinary region. Relatively few data have been published with respect to the role of elastin and glycoproteins in pelvic organ prolapse (POP). Connective tissue of the uterosacral ligament in postmenopausal women with and without genital prolapse was compared. Fifty-nine consecutive women referred for hysterectomy were included in the study. The patients had POP or benign gynecological disease (e.g. myoma of the uterus). Tissue samples from the uterosacral ligament were investigated for localization and distribution of tenascin and elastin using immunofluorescence microscopy. Tissue samples of women with prolapse showed a significantly (p<0.001) weaker immunofluorescent labeling of tenascin compared to samples taken from women without prolapse. Tenascin was detectable in tissues of all women with POP, whereas its immunolabeling was decreased in the uterosacral ligament in women without POP. Intact elastin fibers were observed in tissues of all women without POP, whereas elastin was undetectable or sometimes fragmented in the uterosacral ligament in women with POP. Greater amounts of tenascin and lesser amounts of elastin were therefore found in patients with POP. These results suggest that an altered turnover of connective tissue in the uterosacral ligament might be responsible for the presence of pelvic floor relaxation in postmenopausal women. These data indicate a complex architecture of the extracellular matrix in the uterosacral ligaments, with marked differences in tenascin and elastin expression between postmenopausal women with or without POP.

    Purpose: Development of user-friendly tools for the prediction of single-patient probability of late rectal toxicity after conformal radiotherapy for prostate cancer. Methods and Materials: This multicenter protocol was characterized by the prospective evaluation of rectal toxicity through self-assessed questionnaires (minimum follow-up, 36 months) by 718 adult men in the AIROPROS 0102 trial. Doses were between 70 and 80 Gy. Nomograms were created based on multivariable logistic regression analysis. Three endpoints were considered: G2 to G3 late rectal bleeding (52/718 events), G3 late rectal bleeding (24/718 events), and G2 to G3 late fecal incontinence (LINC, 19/718 events). Results: Inputs for the nomogram for G2 to G3 late rectal bleeding estimation were as follows: presence of abdominal surgery before RT, percentage volume of rectum receiving >75 Gy (V75Gy), and nomogram-based estimation of the probability of G2 to G3 acute gastrointestinal toxicity (continuous variable, which was estimated using a previously published nomogram). G3 late rectal bleeding estimation was based on abdominal surgery before RT, V75Gy, and NOMACU. Prediction of G2 to G3 late fecal incontinence was based on abdominal surgery before RT, presence of hemorrhoids, use of antihypertensive medications (protective factor), and percentage volume of rectum receiving >40 Gy. Conclusions: We developed and internally validated the first set of nomograms available in the literature for the prediction of radio-induced toxicity in prostate cancer patients. Calculations included dosimetric as well as clinical variables to help radiation oncologists predict late rectal morbidity, thus introducing the possibility of RT plan corrections to better tailor treatment to the patient's characteristics, to avoid unnecessary worsening of quality of life, and to provide support to the patient in selecting the best therapeutic approach.

    Purpose: Study goals were to characterize gastrointestinal effects of proton therapy (PT) in a large cohort of patients treated for prostate cancer, identify factors associated with rectal bleeding (RB), and compare RB between patients receiving investigational protocols versus those in outcome-tracking protocols. Methods and Materials: A total of 1285 consecutive patients were treated with PT between August 2006 and May 2010. Potential pre-existing clinical and treatment-related risk factors for rectal toxicity were recorded. Common Terminology Criteria for Adverse Events version 3.0 was used to score toxicity. Results: Transient RB was the predominant grade 2 or higher (GR2+) toxicity after PT, accounting for 95% of gastrointestinal events. GR1 RB occurred in 217 patients (16.9%), GR2 RB in 187 patients (14.5%), and GR3 in 11 (0.9%) patients. There were no GR4 or GR5 events. Univariate analyses showed correlations between GR2+ RB and anticoagulation therapy (P=.008) and rectal and rectal wall dose-volume histogram (DVH) parameters (P<.001). On multivariate analysis, anticoagulation therapy (P=.0034), relative volume of rectum receiving 75 Gy (V75; P=.0102), and relative rectal wall V75 (P=.0017) were significant predictors for G2+ RB. Patients treated with investigational protocols had toxicity rates similar to those receiving outcome-tracking protocols. Conclusions: PT was associated with a low rate of GR2+ gastrointestinal toxicity, predominantly transient RB, which was highly correlated with anticoagulation and rectal DVH parameters. Techniques that limit rectal exposure should be used when possible.

    Abstract Rectal use of a 1% tenofovir (TFV) gel is currently being evaluated for HIV prevention. While careful assessment of mucosal safety of candidate microbicides is a primary concern, tools to assess mucosal toxicity are limited. Mass spectrometry-based proteomics is a sensitive and high-throughput technique that can provide in-depth information on inflammation processes in biological systems. In this study, we utilized a proteomics approach to characterize mucosal responses in study participants involved in a phase 1 clinical trial of a rectal TFV-based gel. Project Gel was a phase 1 randomized (1:1), double-blind, multisite, placebo-controlled trial in which 24 participants received rectal TFV or a universal placebo [hydroxyethyl cellulose (HEC)] over a course of 8 daily doses. Rectal mucosal swabs were collected after 0, 1, and 8 doses and were analyzed by label-free tandem mass spectrometry. Differential protein expression was evaluated using a combination of paired (time-effects) and unpaired (across study arm) t-tests, and multivariate [least absolute shrinkage and selection operator (LASSO)] modeling. Within the TFV arm, 7% (17/249, p < .05) and 10% (25/249, p < .05) of total proteins changed after 1 and 8 daily applications of TFV gel, respectively, compared to 3% (7/249, p < .05) and 6% (16/249, p < .05) in the HEC arm. Biofunctional analysis associated TFV use with a decrease in epidermal barrier proteins (adj. p = 1.21 × 10−10). Multivariate modeling identified 13 proteins that confidently separated TFV gel users (100% calibration and 96% cross-validation accuracy), including the epithelial integrity factors (FLMNB, CRNN, CALM), serpins (SPB13, SPB5), and cytoskeletal proteins (VILI, VIME, WRD1). This study suggested that daily rectal applications of a 1% TFV gel may be associated with mucosal proteome changes involving epidermal development. Further assessment of more extended use of TFV-gel is recommended to validate

    The purpose of this study was to determine if there is a difference between temperature readings obtained using two different electronic temperature devices: one measuring temporal artery temperature (TAT) and one measuring rectal temperature (RT). A comparative single-group design was used with each participant acting as his or her control. The sample consisted of 47 pediatric patients between 3 and 36 months of age. Data analysis revealed no statistically significant differences between TAT and RT; however, concerns related to statistical significance versus clinical significance are discussed.

    Background and aims The incidence of rectal cancer in the European Union is about 35% of the total colorectal cancer incidence. Staging rectal cancer is important for planning treatment. It is essential for the management of rectal cancer to have adequate preoperative imaging, because accurate staging can influence the therapeutic strategy, type of resection, and candidacy for neoadjuvant therapy. The aim of this work is to evaluate the accuracy of endorectal ultrasound (ERUS) in rectal cancer staging. Methods A retrospective study was performed to assess the accuracy of ERUS by analyzing patients discharged from Regional Institute of Gastroenterology and Hepatology (IRGH) Cluj-Napoca, Romania, diagnosed with rectal cancer between 01 January 2011 and 31 December 2013. Patients who were preoperatively staged by other imaging methods and those who had ERUS performed in another service were excluded from the analysis. As inclusion criteria remained ERUS performed for patients with rectal cancer in IRGH Cluj-Napoca where they were also operated. We analyzed preoperative T stage obtained by ERUS and it was compared with the histopathology findings. Results The number of patients discharged with a diagnosis of rectal cancer were 200 (operated – 157) in 2011, 193 (operated – 151) in 2012, and 198 (operated – 142) in 2013. We analyzed a total of 51 cases diagnosed with rectal cancer who performed ERUS in IRGH Cluj-Napoca. The results according to the T stage obtained by ERUS and histopathology test were: Under-stage T2= 25.0%, T3=7.9% of cases; Over-stage T2=25.0%, T3=31.6% and T4=60.0% of cases. Less than 20% of patients underwent preoperative radio-chemotherapy. Conclusions ERUS is a method of staging rectal cancer which is human dependent. ERUS is less accurate for T staging of stenotic tumours, but the accuracy may still be within acceptable limits. Surgeons use ERUS to adopt a treatment protocol, knowing the risk of under-staging and over-staging of this method

    Introduction Defunctioning loop ileostomy (LI) and loop colostomy (LC) are used widely to protect/treat anastomotic leakage after colorectal surgery. However, it is not known which surgical approach has a lower prevalence of surgical complications after low anterior resection for rectal carcinoma (LARRC). Methods We conducted a literature search of PubMed, MEDLINE, Ovid, Embase and Cochrane databases to identify studies published between 1966 and 2013 focusing on elective surgical complications related to defunctioning LI and LC undertaken to protect a distal rectal anastomosis after LARRC. Results Five studies (two randomized controlled trials, one prospective non-randomized trial, and two retrospective trials) satisfied the inclusion criteria. Outcomes of 1,025 patients (652 LI and 373 LC) were analyzed. After the construction of a LI or LC, there was a significantly lower prevalence of sepsis (p=0.04), prolapse (p=0.03), and parastomal hernia (p=0.02) in LI patients than in LC patients. Also, the prevalence of overall complications was significantly lower in those who received LIs compared with those who received LCs (p<0.0001). After closure of defunctioning loops, there were significantly fewer wound infections (p=0.006) and incisional hernias (p=0.007) in LI patients than in LC patients, but there was no significant difference between the two groups in terms of overall complications. Conclusions The results of this meta-analysis show that a defunctioning LI may be superior to LC with respect to a lower prevalence of surgical complications after LARRC.

    Several factors determine overall outcome and possible local recurrence after curative surgery for rectal carcinoma. Surgical performance is usually believed to be the most pertinent factor, followed by adjuvant oncological treatment and tumor histopathology. However, chromosomal instability is common in colorectal cancer and tumor clones are assumed to differ in aggressiveness and potential of causing local recurrence. The aim of this study was, therefore, to evaluate if genetic alterations in primary rectal carcinoma are predictive of local recurrences. A large clinical database with linked bio-bank allowed for careful matching of two patient groups (R0) resected for rectal carcinoma. One group had developed early, isolated local recurrences and the other group seemed cured after 93 months follow-up. DNA from the primary tumors was analysed with array-CGH (comparative genomic hybridization) including 55,000 genomic probes. DNA from all primary tumors in both groups displayed previously reported and well-recognised DNA aberrations in colorectal carcinoma. Significant copy number gains were confirmed in the 4q31.1-31.22 region in DNA from tumors with subsequent local recurrence. Twenty-two affected genes in this region code for products with high relevance in tumor biology (p53 regulation, cell cycle activity, transcription). DNA from rectal carcinoma displayed well-known aberrations as described for colon carcinoma with no obvious prediction of local rectal recurrence. Gains in the 4q31.1-31.22 DNA region are highly potential for local recurrence despite R0 resection to be confirmed in larger patient materials.

    BACKGROUND--The mechanism responsible for the reported high incidence of ventricular arrhythmias in mitral valve prolapse is not clear. Electrocardiographic studies show an increased occurrence of repolarisation abnormalities on the 12 lead surface electrocardiogram, indicating regional differences in ventricular recovery. The purpose of this study was to investigate whether dispersion of refractoriness was an arrhythmogenic mechanism. METHODS--QT dispersion was measured in 32 patients with echocardiographically documented mitral valve prolapse and ventricular arrhythmias on 24 hour Holter recordings. QT dispersion was defined as the difference between the maximum and minimum average QT interval in any of the 12 leads of the surface electrocardiogram. QT dispersion corrected for heart rate was calculated by Bazett's formula. The results were compared with the data from 32 matched controls without a history of cardiac disease. Patients taking drugs that influence the QT interval and patients with a QRS duration > 120 ms were excluded. RESULTS--QT dispersion was greater in patients with mitral valve prolapse than in matched controls (60 (20) v 39 (11 ms) respectively, P < or = 0.001) as was corrected QT (64 (20 ms) v 43 (12 ms) respectively, P < or = 0.001). There was no significant difference in minimum or maximum QT intervals between the two groups. CONCLUSIONS--QT dispersion on the 12 lead surface electrocardiogram was greater in patients with mitral valve prolapse with ventricular arrhythmias than in normal controls, but the maximum QT interval was not increased. The results accord with the hypothesis that regional shortening and lengthening of repolarisation times in patients with mitral valve prolapse may account for the increased dispersion of refractoriness.

    ABSTRACT The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions. These Criteria are reviewed every 2 years by a multidisciplinary expert panel. The development and review of these guidelines includes an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances where evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment. Local recurrence of rectal cancer can result in devastating symptoms for patients, including intractable pain and discharge. Prior treatment can limit subsequent treatment options. Preoperative 5-FU based chemoradiotherapy is the treatment of choice for patients with a local recurrence who did not receive adjuvant therapy after initial resection or who might have received chemotherapy alone. Chemoradiotherapy followed by evaluation for surgery is the preferred treatment for patients who have undergone previous radiotherapy after surgery. The inclusion of surgery has resulted in the best outcomes in a majority of studies. Palliative chemoradiotherapy is appropriate for patients who have received previous radiotherapy whose recurrent disease is considered inoperable. Radiotherapy can be delivered on a standard or hyperfractionated treatment schedule. Newer systemic treatments have improved response rates and given physicians more options for treating patients in this difficult situation. The use of induction chemotherapy prior to radiotherapy is an evolving treatment option. Specialized treatment modalities should be used at institutions with experience in these techniques and preferably in patients enrolled in clinical trials. PMID:22574231

    Background There is an increase in the incidence of rectal carcinoma (RC) in young patients. Methods We analyzed 175 patients with sporadic RC which were divided in two groups according their age: 24 patients ≤40 years and 151 patients >40 years and the two groups were compared in order to determine if the outcomes (especially overall 5-year survival) were different. Results Overall 5-year survival was similar between groups (67.1% for patients over 40 years and 70.4% for those under 40 years, P=0.803). The only differences found were in some clinicopathologic features: patients <40 years showed more dissected lymph nodes (LNs) (21 vs. 15, P=0.035) and more LN metastasis (54.2% vs. 39.1%, P=0.048). In multivariate analysis factors associated with worse survival were incomplete resection and no use of neoadjuvant therapy. Age did not demonstrate prognostic value (P=0.077). Conclusions RC in people ≤40 years demonstrated greater number of LN harvested and LN metastases but oncologic outcomes, especially 5-year overall survival, were similar between groups.

    The results of surgery for rectal cancer have classically been measured through indicators such as morbidity, mortality, and length of hospital stay. In the last few years other parameters have been included that evaluate healthcare quality such as the functional results of the surgical technique employed and quality of life. Total resection of the mesorectum, performed by experienced surgeons, is the surgical technique of choice. Currently, the sphincter can be preserved in 70% of patients. Anastomotic dehiscence after anterior resection of the rectum is the most serious complication and the most important risk factor is the height of the anastomosis. The overall dehiscence rate should be less than 15% and operative mortality should be between 2% and 3%. The colonic reservoir improves functional outcome and consequently it is the procedure of choice to reconstruct transit after low anterior resection. Local recurrence should be less than 10% and 5-year survival should be between 70% and 80%. In general, quality of life is better after anterior resection of the rectum than after abdominoperineal amputation, despite the functional deterioration presented by some patients.

    Rectal suppository is a well-known form of medication and its use is increasing. The commonest shape is one with an apex (pointed end) tapering to a base (blunt end). Because of a general lack of information about mode of insertion, we asked 360 lay subjects (Egyptians and non-Egyptians) and 260 medical personnel (physicians, pharmacists, and nurses) by questionnaire which end they inserted foremost. Apart from 2 individuals, all subjects suggested insertion with the apex foremost. Commonsense was the most frequent basis for this practice (86.9% of lay subjects and 84.6% of medical personnel) followed by information from a relative, a friend, or medical personnel, or from study at medical school. Suppository insertion with the base or apex foremost was compared in 100 subjects (60 adults, 40 infants and children). Retention with the former method was more easily achieved in 98% of the cases, with no need to introduce a finger in the anal canal (1% vs 83%), and lower expulsion rate (0% vs 3%). The designer of the "torpedo-shaped" suppository suggested its insertion with apex foremost. Our data suggest that a suppository is better inserted with the base foremost. Reversed vermicular contractions or pressure gradient of the anal canal might press it inwards.

    Rectal sensation is used as an investigative tool in the diagnosis of anorectal pathology. However, the data obtained are subjective depending on the patient's perception of the sensation. We investigated the hypothesis that sympathetic skin response (SSR) can be used as a tool for objective assessment of the rectal sensation. The SSR was recorded in 24 healthy volunteers (age 37.2 years, 14 men) using a surface electrode applied to the skin of the palmar surface of the subject's hand and a reference electrode to the dorsum of the same hand. The EMG activity of the pelvic floor muscles was registered by a surface electrode fixed to the perineal skin. The subject was asked before and after individual anesthetization of the rectum and palm to report the first rectal and urge sensations during balloon filling of the rectum in increments of 10 ml of saline. Low volume rectal distension effected no sympathetic skin or pelvic floor responses, while larger volumes produced the response. The skin and pelvic floor responses occurred with every rectal sensation and corresponded with the volunteers' subjective perception. Urge suppression was associated with synchronous decrease of skin and pelvic floor responses which disappeared on balloon expulsion. Rectal balloon distension, 20 minutes after individual anesthetization of the rectum or palm produced no palm skin response, which returned however 3 hours later. A novel approach which can objectively define subjective perceptions arising from the rectum has been identified. Rectal sensations produce coordinated sympathetic skin response and pelvic floor activity which seem to be mediated through a reflex which we term the "recto-palmar reflex". Further studies are required to investigate the role of this reflex in defection and sympathetic disorders.

    Introduction The benefits of the laparoscopic approach to colon and rectal surgery do not seem as great as for other laparoscopic procedures. To study this further we decided to review the current literature and the 10-year experience of a surgical group from university teaching hospitals in Montréal, Québec and Toronto in performing laparoscopic colon and rectal surgery. Methods The prospectively designed case series comprised all patients having laparoscopic colon and rectal surgery. The procedures were carried out by a group of 4 surgeons between April 1991 and November 2001. We noted intraoperative complications, any conversions to open surgery, operating time, postoperative complications and postoperative length of hospital stay. Results The group attempted 750 laparoscopic colon and rectal procedures of which 669 were completed laparoscopically. Malignant disease was the indication for surgery in 49.6% of cases. Right hemicolectomy and sigmoid colectomy accounted for 54.5% of procedures performed. Intraoperative complications occurred in 8.3%, with 29.0% of these resulting in conversion to open surgery. The overall rate of conversion to open surgery was 10.8%, most commonly for oncologic concerns. Median operating time was 175 minutes for all procedures. Postoperative complications occurred in 27.5% of procedures completed laparoscopically but were mostly minor wound complications. Pulmonary complications occurred in only 1.0%. The anastomotic leak rate was 2.5%. The early reoperation rate was 2.4%. Postoperative mortality was 2.2%. No port site metastases have yet been detected. The median postoperative length of stay was 5 days. Conclusions The clinical outcomes of laparoscopic colon and rectal surgery in this 10-year experience are consistent with numerous cohort studies and randomized clinical trials. Laparoscopic colon and rectal surgery in the hands of well-trained surgeons can be performed safely with short hospital stay, low analgesic requirements

    The patient, a 40-year-old woman, underwent total gastrectomy and excision of the pancreatic tail, spleen and gallbladder for gastric cancer in September 2000. The lesion was judged to be P1, SE, H0, N2 and Stage IV and the patient was managed on a regular schedule as an outpatient. In September 2004, she passed blood-stained feces and rectal palpation detected a hard nodule at the anterior rectal wall. A fiber optic examination of the sigmoid colon detected an ulcerous lesion with a hemorrhage at the anterior rectal wall. A biopsy revealed the lesion to be Group V poorly differentiated adenocarcinoma. Starting in October 2004, 100 mg/day of TS-1 was administered for 3 weeks; intravenous drip infusion of 100 mg/body of CDDP was conducted in the second week for a period of 24 hours. After 3 courses of this regimen, a fiber optic examination of the colon conducted in February 2005 no longer detected the rectal tumor, leaving only a cicatrix. Upon a CT examination, the para-aortic lymph nodes that had been enlarged were notably reduced in size and an improvement was eminent in the hypertrophic rectal wall. The patient no longer experienced constipation or melena. Her clinical course is being observed while an oral administration of 100 mg/day of TS-1 continues.

    Purpose To assess the effect of a rectal enema on interfraction prostate movement in bone alignment (BA) for prostate radiotherapy (RT), we analyzed the spatial difference in prostates in a bone-matched setup. Materials and Methods We performed BA retrospectively with data from prostate cancer patients who underwent image-guided RT (IGRT). The prostate was identified with implanted fiducial markers. The setup for the IGRT was conducted with the matching of three fiducial markers on RT planning computed tomography images and those on two oblique kV x-ray images. Offline BA was performed at the same position. The coordinates of a virtual prostate in BA and a real prostate were obtained by use of the ExaxTrac/NovalisBody system, and the distance between them was calculated as the spatial difference. Interfraction prostate displacement was drawn from the comparison of the spatial differences. Results A total of 15 patients with localized prostate cancer treated with curative hypofractionated IGRT were enrolled. A total of 420 fractions were analyzed. The mean of the interfraction prostate displacements after BA was 3.12±2.00 mm (range, 0.20-10.53 mm). The directional difference was profound in the anterior-posterior and supero-inferior directions (2.14±1.73 mm and 1.97±1.44 mm, respectively) compared with the right-left direction (0.26±0.22 mm, p<0.05). The required margin around the clinical target volume was 4.97 mm with the formula of van Herk et al. Conclusions The interfraction prostate displacement was less frequent when a rectal enema was performed before the procedure. A rectal enema can be used to reduce interfraction prostate displacement and resulting clinical target volume-to-planning target volume margin. PMID:24466393

    Context: Cancer patients’ participation in social, recreational, and civic activities is strongly associated with quality of life (QOL), but these activities are not well integrated into cancer survivorship research or interventions. Objective: Test the hypothesis that for long-term (≥ 5 years) survivors of rectal cancer, clinical factors (type of surgery and bowel function) are associated with long-term participation in activities and that participation in activities is associated with long-term QOL. Design: Observational study with longitudinal and cross-sectional components. Main Outcome Measures: Participation in activities and QOL. Tumor registry records were used to identify patients and obtain clinical data; surveys assessed participation and QOL. Using general linear models, we analyzed participation in activities in relation to type of surgery and bowel function after adjustment for potential confounders. We analyzed overall QOL relative to participation in activities after adjustment. Results: A total of 567 rectal cancer survivors completed a mailed questionnaire. Overall response rate was 61%. The type of operation (p < 0.0001), receipt of radiation therapy (p = 0.002), and bowel function (p < 0.0001) were associated with participation in activities. Participation in activities was the strongest predictor of QOL (p < 0.0001), explaining 20% of the variance (R2) in QOL, with all other variables together accounting for another 18% of the variance. Conclusion: The importance of participation in activities on rectal cancer survivors’ QOL is underappreciated. We recommend revising QOL instruments used in cancer care and research to include questions about participation in activities. Interventions should address maintenance of preferred activities and adoption of new, fulfilling activities. PMID:28241904

    Introduction: Epidural venous plexus enlargement, presenting with low back pain and radiculopathy, is an uncommon cause of nerve roots impingement. This condition commonly mimics a herniated nucleus pulposus radiologically. The radiological diagnosis is often missed and the diagnosis is made during the surgery. We are hereby presenting 2 such cases of epidural varices mimicking intervertebral disc prolapse with lumbar radiculopathy. Case Report: Case 1: 43 yr old female presented with acute exacerbation of low back ache and significant right L5–S1 radiculopathy without neurological deficit. MRI reported as L5-S1 disc prolapse. Intra-operatively engorged dilated epidural vein seen compressing S1 nerve root. Associated Disc bulge removed and Coagulative ablation of the dilated epidural vein was performed Case 2: 45 year old male manual labourer presented with backache with left sided sciatica since 8 months, increased in severity since past 1month associated with sensory blunting in L5 and S1 dermatomes. Neurologic examination revealed normal muscle power in his lower extremities. Sensations was blunted in L5 and S1 dermatomes. MRI was reported as L5-S1 disc prolapsed compressing left S1 nerve root. Decompression of the L5–S1 intervertebral space was performed through a left –sidelaminotomy. Large, engorged serpentine epidural veins was found in the axilla of S1 nerve root, compressing it. Coagulative ablation of the dilated epidural vein was performed. Retrospectively, features of epidural varices were noted in the preoperative magnetic resonance imaging scans. Both patients had significant improvement in radiculopathy immediate postoperatively, and sensory symptoms resolved over the next 6 weeks in second case. At recent follow up, both patients had significant relief of symptoms and no recurrent radicular symptoms. Conclusion: An abnormal dilated epidural venous plexus that mimics a herniated lumbar disc is a rare entity. This pathology should be always kept

    Purpose: Knowledge of sexual problems after pre- or postoperative radiotherapy (RT) with 50 Gy for rectal cancer is limited. In this study, we aimed to compare self-rated sexual functioning in irradiated (RT+) and nonirradiated (RT-) male patients at least 2 years after surgery for rectal cancer. Methods and Materials: Patients diagnosed with rectal cancer from 1993 to 2003 were identified from the Norwegian Rectal Cancer Registry. Male patients without recurrence at the time of the study. The International Index of Erectile Function, a self-rated instrument, was used to assess sexual functioning, and serum levels of serum testosterone were measured. Results: Questionnaires were returned from 241 patients a median of 4.5 years after surgery. The median age was 67 years at survey. RT+ patients (n = 108) had significantly poorer scores for erectile function, orgasmic function, intercourse satisfaction, and overall satisfaction with sex life compared with RT- patients (n = 133). In multiple age-adjusted analysis, the odds ratio for moderate-severe erectile dysfunction in RT+ patients was 7.3 compared with RT- patients (p <0.001). Furthermore, erectile dysfunction of this degree was associated with low serum testosterone (p = 0.01). Conclusion: RT for rectal cancer is associated with significant long-term effects on sexual function in males.

    One-hundred and thirty-two patients with cervix carcinoma who were treated with whole pelvis irradiation and two intracavitary applications had bladder and rectal dosimetry during brachytherapy with contrast agents placed into the bladder and rectum prior to orthogonal simulator radiographs. Doses were computer calculated at points A and B, F (bladder), R1 (rectum), and R2 (rectosigmoid). Late occurring bladder and rectal complications were graded on a severity scale of 1 to 3, and 14% had grade 2 or 3 injuries (9% developed fistulas). Statistical evaluation of the data showed that severe bladder and rectal injuries occur more commonly in stage IIIA and IIIB disease and in those receiving high external beam doses (5000 rad +). Analysis of variance tests revealed a significant correlation of brachytherapy dose to points R1 and R2 with severe rectal injuries but there was not a correlation of dose to F with bladder injuries. Nor was there correlation of injuries with dose to point A or the milligram-hour dose. We conclude that our technique for rectal dosimetry is adequate but that an improved technique of bladder dosimetry is needed. Also, when combining whole pelvis irradiation with two intracavitary applications (4000 rad to point A), the whole pelvis dose should probably not exceed 4000-4500 rad.

    Investigating epidemiology of metastatic colon and rectal cancer is challenging, because cancer registries seldom record metastatic sites. We used a population based approach to assess metastatic spread in colon and rectal cancers. 49,096 patients with colorectal cancer were identified from the nationwide Swedish Cancer Registry. Metastatic sites were identified from the National Patient Register and Cause of Death Register. Rectal cancer more frequently metastasized into thoracic organs (OR = 2.4) and the nervous system (1.5) and less frequently within the peritoneum (0.3). Mucinous and signet ring adenocarcinomas more frequently metastasized within the peritoneum compared with generic adenocarcinoma (3.8 [colon]/3.2 [rectum]), and less frequently into the liver (0.5/0.6). Lung metastases occurred frequently together with nervous system metastases, whereas peritoneal metastases were often listed with ovarian and pleural metastases. Thoracic metastases are almost as common as liver metastases in rectal cancer patients with a low stage at diagnosis. In colorectal cancer patients with solitary metastases the survival differed between 5 and 19 months depending on T or N stage. Metastatic patterns differ notably between colon and rectal cancers. This knowledge should help clinicians to identify patients in need for extra surveillance and gives insight to further studies on the mechanisms of metastasis. PMID:27416752

    Purpose The aim of this study was to assess the voiding dysfunction after rectal cancer surgery with total mesorectal excision (TME). Methods This was part of a prospective study done in the rectal cancer patients who underwent surgery with TME between November 2006 and June 2008. Consecutive uroflowmetry, post-voided residual volume, and a voiding questionnaire were performed at preoperatively and postoperatively. Results A total of 50 patients were recruited in this study, including 28 male and 22 female. In the comparison of the preoperative data with the postoperative 3-month data, a significant decrease in mean maximal flow rate, voided volume, and post-voided residual volume were found. In the comparison with the postoperative 6-month data, however only the maximal flow rate was decreased with statistical significance (P=0.02). In the comparison between surgical methods, abdominoperineal resection patients showed delayed recovery of maximal flow rate, voided volume, and post-voided residual volume. There was no significant difference in uroflowmetry parameters with advances in rectal cancer stage. Conclusions Voiding dysfunction is common after rectal cancer surgery but can be recovered in 6 months after surgery or earlier. Abdominoperineal resection was shown to be an unfavorable factor for postoperative voiding. Larger prospective study is needed to determine the long-term effect of rectal cancer surgery in relation to male and female baseline voiding condition. PMID:22087426

    IMPORTANCE Over 300,000 surgeries are performed annually in the United States for pelvic organ prolapse. Sacrospinous ligament fixation (SSLF) and uterosacral ligament suspension (ULS) are commonly performed transvaginal surgeries to correct apical prolapse. Little is known about their comparative efficacy and safety, and it is unknown whether perioperative behavioral therapy with pelvic floor muscle training (BPMT) improves outcomes of prolapse surgery. OBJECTIVE To compare outcomes between 1) SSLF and ULS and 2) perioperative BPMT and usual perioperative care in women undergoing surgery for vaginal prolapse and stress urinary incontinence. DESIGN, SETTING AND PARTICIPANTS Multi-center, 2×2 factorial randomized trial of 374 women undergoing surgery to treat both apical vaginal prolapse and stress urinary incontinence was conducted between 2008 and 2013 at 9 U.S. medical centers. Two-year follow-up rate was 84.5%. INTERVENTIONS Surgical intervention: Transvaginal surgery including mid-urethral sling with randomization to SSLF (n = 186) or ULS (n=188); Behavioral intervention: Randomization to perioperative BPMT (n = 186) or usual care (n=188). MAIN OUTCOME MEASURES The primary outcome for the surgical intervention (surgical success) was defined as: 1) no apical descent greater than one-third into vaginal canal or anterior or posterior vaginal wall beyond the hymen (anatomic success); 2) no bothersome vaginal bulge symptoms and 3) no retreatment for prolapse at 2 years. For the behavioral intervention, primary outcome at 6 months was urinary symptom scores (Urinary Distress Inventory; range 0–300, higher scores worse), and primary outcomes at 2 years were prolapse symptom scores (Pelvic Organ Prolapse Distress Inventory; range 0–300, higher scores worse) and anatomic success. RESULTS At 2 years, surgical group was not significantly associated with surgical success rates [ULS 59.2% (93/154) vs. SSLF 60.5% (92/152), OR 0.9 (95% CI 0.6, 1.5)] or serious adverse

    Since individualized therapy becomes more and more important in the treatment of rectal cancer, an accurate and effective approach should be established in the clinical settings to help physicians to make their decisions. Circulating tumor cells (CTCs), originated from either primary or metastatic cancer, could provide important information for diagnosis and monitoring of cancer. However, the implication and development of CTCs are limited due to the extreme rarity of these tumor cells. In this study we fabricated a simple and high-performance microfluidic device, which exploited numerous filtered microchannels in it to enrich the large-sized target tumor cells from whole blood. A very high CTC capture efficiency (average recovery rate: 94%) was obtained in this device at the optimum flow rate of 0.5 mL/h and channel height of 5 µm. Additionally, we used this device for detecting CTCs in 60 patients with rectal cancer. The CTC counts of rectal cancer patients were significantly higher than those in healthy subjects. Furthermore, the CTC counts detected by this device were significantly higher than those by EpCAM bead-based method for rectal cancer patients with various stage. Especially, for localized rectal cancer patients, the positive rates of samples with more than 3 CTCs per 5 mL blood by use of microdevice vs. EpCAM-based ones were 100% vs. 47%, respectively. Thus, this device provides a new and effective tool for accurate identification and measurement of CTCs in patients with rectal cancer, and has broad potential in clinical practice.

    Single-fibre electromyography of the pubococcygeus muscle of the pelvic floor was performed in 69 asymptomatic women and 105 women with stress incontinence of urine or genitourinary prolapse or both. The results suggest that partial denervation of the pelvic floor with subsequent reinnervation is a normal accompaniment of ageing and is increased by childbirth. Women with stress incontinence of urine or genitourinary prolapse or both have a significant increase in denervation of the pelvic floor compared with asymptomatic women.

    We present a case of an 81-year-old man who presented with a large recto-urethral fistula resulting in prolapsing bladder through the anus. A multi-disciplinary approach with urology, colorectal surgery and plastic surgery was utilized for management of the prolapse with excellent postoperative result. This unique scenario enabled a transanal cystoprostatectomy; the procedure was completed using a natural orifice without transabdominal surgery. PMID:26793568

    A 5 year-old spayed female Cavalier King Charles Spaniel was presented after a 3- to 5-day onset of severe respiratory distress. The dog also had a history of several episodes of syncope prior to presentation. A comprehensive diagnostic investigation revealed a midsystolic click sound on cardiac auscultation, signs of left sided cardiac enlargement in ECG and thoracic radiography, mitral valvular leaflet protrusion into left the atrium, decreased E-point-to septal separation (EPSS) and mitral regurgitated flow in echocardiography, all of which are characteristic signs of mitral valvular prolapse. After intensive care with diuretics [corrected] and a vasodilator with oxygen supplement, the condition of the dog was stabilized. The dog was then released and is being medicated with angiotensin converting enzyme (ACE) inhibitor with regular follow-up.

    In view of the close relationship of mitral valve prolapse (MVP) and chest deformity, seven patients of MVP associated with flat chest were echocardiographically evaluated, and the results were compared with those of 43 normal control subjects, 29 cases with flat chest, and patients with MVP either of the anterior (25 cases) or posterior (21 cases) leaflet. MVP associated with flat chest was observed in the anterior leaflet in all cases. MVP was related to the dislocation of the two mitral leaflets caused by the displaced posterior mitral ring observed by two-dimensional echocardiography. The transition type was observed among the cases with or without dislocation of the mitral ring in cases with flat chest.

    A female patient in her mid 40s presents with heavy menstrual bleeding (HMB) and a history of spotting/irregular light per vagina (PV) bleeding since intrauterine system (IUS) insertion 1 year ago. She is known to have submucosal uterine fibroid (SMUF). The patient reported abdominal pain and sudden onset of ‘miscarriage-like’ HMB with clots 2 days ago. On speculum examination there was a smooth round-shaped mass lying over the external cervical os. On bimanual examination PV, a round-shaped smooth mass of a walnut's size was palpable in the upper third of the vagina. Subsequent ultrasound imaging revealed an SMUF prolapsed into the vagina. Further surgical treatment was undertaken. Histology showed a fibroid (leiomyoma) with no evidence of malignancy. PMID:24739657

    It is presumed that extrinsic afferent nerves link the rectum to the central nervous system. However, the anatomical/functional existence of such nerves has never previously been demonstrated in humans. Therefore, we aimed to identify and make electrophysiological recordings in vitro from extrinsic afferents, comparing human rectum to colon. Sections of normal rectum and colon were procured from anterior resection and right hemicolectomy specimens, respectively. Sections were pinned and extrinsic nerves dissected. Extracellular visceral afferent nerve activity was recorded. Neuronal responses to chemical [capsaicin and “inflammatory soup” (IS)] and mechanical (Von Frey probing) stimuli were recorded and quantified as peak firing rate (range) in 1-s intervals. Twenty-eight separate nerve trunks from eight rectums were studied. Of these, spontaneous multiunit afferent activity was recorded in 24 nerves. Peak firing rates increased significantly following capsaicin [median 6 (range 3–25) spikes/s vs. 2 (1–4), P < 0.001] and IS [median 5 (range 2–18) spikes/s vs. 2 (1–4), P < 0.001]. Mechanosensitive “hot spots” were identified in 16 nerves [median threshold 2.0 g (range 1.4–6.0 g)]. In eight of these, the threshold decreased after IS [1.0 g (0.4–1.4 g)]. By comparison, spontaneous activity was recorded in only 3/30 nerves studied from 10 colons, and only one hot spot (threshold 60 g) was identified. This study confirms the anatomical/functional existence of extrinsic rectal afferent nerves and characterizes their chemo- and mechanosensitivity for the first time in humans. They have different electrophysiological properties to colonic afferents and warrant further investigation in disease states. PMID:27789454

    This paper examines the hypothesis that a reduction in the distal mural margin during anterior resection for sphincter conservation in rectal cancer excision is safe, provided total mesorectal excision is undertaken with wash-out of the clamped rectum. One hundred ninety-two patients underwent anterior resection and 21 (less than 10%) patients underwent abdomino-perineal excision (APE) by one surgeon (RJH). Anterior resections were classified as "curative" (79%) and "non-curative" (21%); in the "curative" sub-group less than 4% of patients developed local recurrence. The series was retrospectively analyzed for the effect of mural margins on local recurrence with 152 patients undergoing "curative" anterior resections and 40 patients undergoing "non-curative" resections. In the 152 specimens from curative resections, 110 had a resection margin greater than 1 cm and 42 had a resection margin less than 1 cm. Four patients developed local recurrence in the greater than 1 cm margin group (95% confidence interval: 0.8%-7.8%) and no patients developed local recurrence in the less than or equal to 1 cm margin group (95% confidence interval: 0%-5.9%). In each patient with local recurrence a cause for failure was apparent. There was no statistically significant difference in local recurrence rate between the less than or equal to 1 cm margin group and the greater than 1 cm margin group. A reduction in resection margin therefore did not compromise survival after anterior resection. The significance of lateral resection margins is discussed. The role of deep radiotherapy and cytotoxics are considered.(ABSTRACT TRUNCATED AT 250 WORDS)

    Any abnormality of collagen may affect the tissues with higher collagen content, e.g., joints, heart valves, and great arteries. Mitral valve prolapse (MVP) is a characteristic of generalized collagen abnormality. Nasal septum (NS) is constituted by osseous and cartilaginous septums that are highly rich in collagen. We evaluated the co-existence of deviation of NS (DNS) in patients with MVP. We retrospectively evaluated the recordings of echocardiographic and nasal examinations of subjects with MVP and DNS. We analyzed the features of MVP and anatomical classification of DNS among subjects. Totally, 74 patients with DNS and 38 subjects with normal nasal passage were enrolled to the study. Presence of MVP was significantly higher in patients with DNS compared to normal subjects (63 vs 26%, p < 0.001). Prolapse of anterior, posterior and both leaflets was higher in patients with DNS. Thickness of anterior mitral leaflet was significantly increased in patients with DNS (3.57 ± 0.68 vs 4.59 ± 1.1 mm, p < 0.001) compared to normal subjects. Type I, II, and III, IV DNS were higher in frequency in patients with MVP while type V and VI were higher in normal subjects. DNS is highly co-existent with MVP and increased thickness of mitral anterior leaflet. Generalized abnormality of collagen which is the main component of mitral valves and nasal septum may be accounted for co-existence of MVP and DNS. Also co-existence of them may exaggerate the symptoms of patients with MVP due to limited airflow through the nasal passage.

    Objective: To assess the outcome and safety of sacrohysteropexy as uterus conserving surgery for pelvic organ prolapse in young women and to assess patients’ satisfaction with the procedure. Methods: This is a case series of patients operated at Sind Government Lyari General Hospital and Civil Hospital Karachi, between January, 2007 to October, 2015. Data of the patients who had sacrohysteropexy were reviewed. Complications during surgery and post-operative period including haemorrhage, visceral injury, paralytic ileus and peritonitis were studied. Success of procedure, need of blood transfusion, hospital stay and condition on discharge and six weeks follow-up were noted. Data were analyzed using SPSS version 16. Mean ± SD was calculated for numerical, while frequencies were computed for categorical variables. Results: Data of 60 patients were reviewed. Early post-operative success was 100%. Duration of surgery was less than two hours in 57 (95%) patients. Blood loss was negligible in majority of cases. Out of all 60 cases, 52 (86.7%) did not suffer any complication. One patient had ureteric injury, while one patient sustained bowel injury. Two patients had paralytic ileus. Four patients suffered from abdominal wound infection. All patients were managed satisfactorily. Mean duration of stay in hospital was four days. Upon follow up 96.7% patients were satisfied with results of operative procedure. Sixteen (26.7%) patients complained of backache on follow-up visit. Conclusion: This review concludes that sacrohysteropexy was successful in all cases in early post-operative period. It is a safe procedure and should be considered as an option for the treatment of pelvic organ prolapse in young women, in whom uterine conservation is required. PMID:27882016

    There are two conventional treatments for clinically resectable rectal cancer. The first is surgery followed by postoperative combined-modality therapy if the tumor is T3 and/or N1/2. The second, if the tumor is ultrasound T3 or clinical T4, is preoperative combined-modality therapy followed by surgery and postoperative chemotherapy. There are a number of new chemotherapeutic agents that have been developed for the treatment of colorectal cancer. Phase I/II trials are examining the use of new chemotherapeutic agents in combination with pelvic radiation therapy, most commonly in the preoperative setting. There is considerable interest in integrating irinotecan (Camptosar) into preoperative combined-modality therapy regimens for rectal cancer. Based on these trials, the recommended regimen for patients who receive irinotecan-based combined-modality therapy is continuous infusion fluorouracil (5-FU), irinotecan, and pelvic radiation. New trials examining preoperative combined-modality therapy regimens substituting capecitabine (Xeloda) for continuous infusion 5-FU are in progress.

    The treatment for patients with locally advanced, resectable rectal cancer has evolved over the years. Various combinations and sequences of chemotherapy, radiation therapy, and total mesorectal excision (TME)-based surgery are the mainstay of current therapy. Preoperative combined chemoradiation, followed by surgery, is now the preferred treatment strategy, with the majority of patients receiving either infusion fluorouracil (5-FU) or capecitabine (Xeloda) with radiation. Clinical trials with oxaliplatin (Eloxatin)-based neoadjuvant chemoradiation have not shown improvement in the pathologic complete response rate (pCR) compared with 5-FU; however, final data addressing local recurrence rates and disease-free survival are pending.The use of adjuvant chemotherapy following preoperative chemoradiation and surgery has not been optimally defined. Some studies have shown that patients who obtained significant pathologic downstaging after chemoradiation and surgery have improved survival with the use of adjuvant chemotherapy. Since FOLFOX (folinic acid, 5-FU, and oxaliplatin) is the preferred adjuvant chemotherapy regimen for stage III colon cancer based on randomized clinical trial results, FOLFOX is also recommended for rectal cancer patients as an adjuvant therapy approach.

    Purpose Xanthogranulomatous prostatitis (XP) is a rare form of nonspecific granulomatous prostatitis that can clinically mimic high-grade prostatic carcinoma. It is difficult to diagnose it definitely in clinical settings. Methods We report a case of XP with prostate-rectal fistula and review the relevant literatures. Result A 75-year-old man presented with rectal bleeding when he urinated. A locally advanced carcinoma of prostate was suspected initially following the physical, imaging, and hematologic examinations. Subsequently on histopathological and immunohistochemical staining after needle biopsy of the prostate, a diagnosis of XP was made definitely. The patient was catheterized temporarily and treated with tamsulosin and estrogen. The patient underwent uneventful recovery after this conservative therapy. Conclusion Histologic and immunohistochemical analyses are valuable in differentially diagnosing XP from high-grade prostate carcinoma. Treatment strategy of XP in principle is recommended to be the conservative method. Long-term follow-up earns are highly regarded considering the possibility of coexisting prostate cancer.

    In the past two decades, substantial progress has been made in the adjuvant management of colorectal cancer. Chemotherapy has improved overall survival in patients with node-positive (N+) disease. In contrast with colon cancer, which has a low incidence of local recurrence, patients with rectal cancer have a higher incidence requiring the addition of pelvic radiation therapy (chemoradiation). Patients with rectal cancer have a number of unique management considerations: for example, the role of short-course radiation, whether postoperative adjuvant chemotherapy is necessary for all patients, and if the type of surgery following chemoradiation should be based on the response rate. More accurate imaging techniques and/or molecular markers may help identify patients with positive pelvic nodes to reduce the chance of overtreatment with preoperative therapy. Will more effective systemic agents both improve the results of radiation as well as modify the need for pelvic radiation? This review will address these and other controversies specific to patients with rectal cancer.

    Despite its abundant vascularization and extensive circulatory communication with neighboring organs, metastases to the penis are a rare event. A 57-year-old male, who had undergone total pelvic exenteration for rectal cancer sixteen months earlier, demonstrated an abnormal uptake within his penis by positron emission tomography/computed tomography. A single elastic nodule of the middle penis shaft was noted deep within Bucks fascia. No other obvious recurrent site was noted except the penile lesion. Total penectomy was performed as a curative resection based on a diagnosis of isolated penile metastasis from rectal cancer. A histopathological examination revealed an increase of well differentiated adenocarcinoma in the corpus spongiosum consistent with his primary rectal tumor. The immunohistochemistry of the tumor cells demonstrated positive staining for cytokeratin 20 and negative staining for cytokeratin 7, which strongly supported a diagnosis of penile metastasis from the rectum. The patient is alive more than two years without any recurrence.

    Neoadjuvant chemoradiotherapy has become the standard treatment for locally advanced rectal cancer. Neoadjuvant chemoradiotherapy not only can reduce tumor size and recurrence, but also increase the tumor resection rate and anus retention rate with very slight side effect. Comparing with preoperative chemotherapy, preoperative chemoradiotherapy can further reduce the local recurrence rate and downstage. Middle and low rectal cancers can benefit more from neoadjuvant chemradiotherapy than high rectal cancer. It needs to refine the selection of appropriate patients and irradiation modes for neoadjuvant chemoradiotherapy. Different therapeutic reactions to neoadjuvant chemoradiotherapy affect the type of surgical techniques, hence calling for the need of much attention. Furthermore, many problems such as accurate staging before surgery, selection of suitable neoadjuvant chemoradiotherapy method, and sensitivity prediction to preoperative radiotherapy need to be well settled.

    Minimally invasive surgery has changed the way we manage many colon and rectal pathologies. Multiple techniques, from straight laparoscopic procedures, to hand-assisted and single-port techniques are available, requiring surgeons to go through various learning curves. Robotic surgery is a relatively novel technique in general surgery which appears to hold most promise for rectal resection. Laparoscopic rectal procedures are difficult, and even in experienced hands, conversion rates are around 17%. Robotic surgery may be a point of difference in these cases, despite a long learning curve and higher costs. This article will describe the role of robotics in colorectal surgery. Room set up, port placement, and docking strategies will be described for common procedures, with emphasis on a hybrid robotic low anterior resection. PMID:26491407

    The aim of the present study was to investigate the levels of the serum tumor biomarker carcinoembryonic antigen (CEA) in patients with carcinoma of the colon and rectum in different clinical stages. Colorectal cancer (CRC) is one of the most commonly diagnosed types of cancer worldwide and previous studies have reported rapidly updated therapeutic regimes. While the majority of studies focus on CRC as a single entity, certain studies distinguish colon cancer (CC) from rectal cancer (RC), as there is a hypothesis stating that CC and RC are two naturally different entities. CEA is reported to be an important tumor-associated antigen overexpressed in CRC, which is routinely detected as a significant indicator of CRC. Our study aimed to identify potential differences in the expression of CEA between CC and RC, which may, to some degree, reflect the natural differences between the two. We investigated 240 CRC cases between July, 2010 and December, 2012 from The First and Second Affiliated Hospitals of Dalian Medical University, including 117 CC and 123 RC patients with tumors classified by Duke's staging as A-D. The serum CEA level was measured preoperatively by radioimmunoassays as a routinely used auxiliary indicator. The expression of CEA differed between CC and RC, with the former exhibiting variation among the four stages, whereas no variation was observed in RC. In addition, there were differences between CC and RC regarding the CEA level in stage C and D. Furthermore, the CEA level in stage C of CC was significantly lower compared to that in any other stage. In conclusion, the intrinsic distribution of the CEA level between CC and RC suggests that CC and RC may be two naturally different entities; the significantly low CEA level in stage C of CC indicates that stage C may be crucial in the evolution of CC.

    Background: Foxp3+ regulatory T cells (Tregs) play a vital role in preventing autoimmunity, but also suppress antitumour immune responses. Tumour infiltration by Tregs has strong prognostic significance in colorectal cancer, and accumulating evidence suggests that chemotherapy and radiotherapy efficacy has an immune-mediated component. Whether Tregs play an inhibitory role in chemoradiotherapy (CRT) response in rectal cancer remains unknown. Methods: Foxp3+, CD3+, CD4+, CD8+ and IL-17+ cell density in post-CRT surgical samples from 128 patients with rectal cancer was assessed by immunohistochemistry. The relationship between T-cell subset densities and clinical outcome (tumour regression and survival) was evaluated. Results: Stromal Foxp3+ cell density was strongly associated with tumour regression grade (P=0.0006). A low stromal Foxp3+ cell density was observed in 84% of patients who had a pathologic complete response (pCR) compared with 41% of patients who did not (OR: 7.56, P=0.0005; OR: 5.27, P=0.006 after adjustment for presurgery clinical factors). Low stromal Foxp3+ cell density was also associated with improved recurrence-free survival (HR: 0.46, P=0.03), although not independent of tumour regression grade. Conclusions: Regulatory T cells in the tumour microenvironment may inhibit response to neoadjuvant CRT and may represent a therapeutic target in rectal cancer. PMID:26645238

    Purpose To evaluate the reproducibility of radiomics features by repeating computed tomographic (CT) scans in rectal cancer. To choose stable radiomics features for rectal cancer. Results Volume normalized features are much more reproducible than unnormalized features. The average value of all slices is the most reproducible feature type in rectal cancer. Different filters have little effect for the reproducibility of radiomics features. For the average type features, 496 out of 775 features showed high reproducibility (ICC ≥ 0.8), 225 out of 775 features showed medium reproducibility (0.8 > ICC ≥ 0.5) and 54 out of 775 features showed low reproducibility (ICC < 0.5). Methods 40 rectal cancer patients with stage II were enrolled in this study, each of whom underwent two CT scans within average 8.7 days. 775 radiomics features were defined in this study. For each features, five different values (value from the largest slice, maximum value, minimum value, average value of all slices and value from superposed intermediate matrix) were extracted. Meanwhile a LOG filter with different parameters was applied to these images to find stable filter value. Concordance correlation coefficients (CCC) and inter-class correlation coefficients (ICC) of two CT scans were calculated to assess the reproducibility, based on original features and volume normalized features. Conclusions Features are recommended to be normalized to volume in radiomics analysis. The average type radiomics features are the most stable features in rectal cancer. Further analysis of these features of rectal cancer can be warranted for treatment monitoring and prognosis prediction. PMID:27669756

    Objectives: The continuing search for interventions, which address the incidence and grade of rectal toxicities associated with radiation treatment of prostate cancer, is a major concern. We are reporting an investigational trial using human collagen to increase the distance between the prostate and anterior rectal wall, thereby decreasing the radiation dose to the rectum. Methods: This is a pilot study evaluating the use of human collagen as a displacing agent for the rectal wall injected before starting a course of intensity-modulated radiotherapy (IMRT) for prostate cancer. Using a transperineal approach, 20 mL of human collagen was injected into the perirectal space in an outpatient setting. Computerized IMRT plans were performed pre- and postcollagen injection, and after a patient completed their radiotherapy, to determine radiation dose reduction to the rectum associated with the collagen injection. Computed tomography scans were performed 6 months and 12 months after completing their radiotherapy to evaluate absorption rate of the collagen. All patients were treated with IMRT to a dose of 75.6 Gy to the prostate. Results: Eleven patients were enrolled into the study. The injection of human collagen in the outpatient setting was well tolerated. The mean separation between the prostate and anterior rectum was 12.7 mm. The mean reduction in dose to the anterior rectal wall was 50%. All men denied any rectal symptoms during the study. Conclusions: The transperineal injection of human collagen for the purpose of tissue displacement is well tolerated in the outpatient setting. The increased separation between the prostate and rectum resulted in a significant decrease in radiation dose to the rectum while receiving IMRT and was associated with no rectal toxicities.

    Rectal fist insertion (fist fucking) is an uncommon and potentially dangerous sexual practice. This is usually a homosexual activity, but can also be a heterosexual or an autoerotic practice. One known death has been reported associated with rectal fist insertion, in which the complications of anal and colonic tears and bleeding had occurred (see Editor's note). The possibility of drug overdose is also probable, as drugs and alcohol are commonly introduced into the rectum to promote sphincter relaxation and to ease the discomfort of anal dilatation.

    Multiphoton microscopy (MPM) has high resolution and sensitivity. In this study, MPM was used to image microstructure of human rectal mucosa. The morphology and distribution of the main components in mucosa layer, absorptive cells and goblet cells in the epithelium, abundant intestinal glands in the lamina propria and smooth muscle fibers in the muscularis mucosa were clearly monitored. The variations of these components were tightly relevant to the pathology in gastrointestine system, especially early rectal cancer. The obtained images will be helpful for the diagnosis of early colorectal cancer.

    Treatment of rectal cancer over the last two decades has evolved with changes in techniques of surgery and radiation based on national and international trials. Preoperative adjuvant radiation is now preferred over postoperative adjuvant radiation, and total mesorectal excision with preservation of pelvic nerves is the gold standard for surgical treatment of rectal cancer. Preservation of the anal sphincter without compromising oncological outcome is an additional benefit for patients with carcinoma in the distal rectum. Further progress in imaging and a multidisciplinary team approach will facilitate individualization of treatment strategy with more focus on quality of life.

    Background Overall declines in incidence of rectal cancer (RC) in patients older than 50 years have been mostly attributed to improvement in treatment modalities and introduction of age-based screening. Recent studies, however, have shown a rise in the incidence of RC in patients younger than 50 years. The etiology of early-onset (EO) RC is not well understood. The aim of this study is to elucidate the molecular features of (EO) RC and show its uniqueness compared to late-onset (LO) disease. Methods Two cohorts of patients with sporadic RC were identified. Tumors and matching non-involved tissues from six (EO) RC patients (< 50 years) and six (LO) RC patients (>65 years) were obtained from Pathology archives. Deparaffinized tissues were macro-dissected from FFPE sections, RNA isolated and used for expression profiling of 770 cancer related genes representing 13 canonical pathways. Statistical analysis was performed using the Gene Expression R-script module within the nCounter software v2.6. A gene was considered to be above background if the average count for the target gene was greater than the average counts for the eight negative control genes and if the P value of the t-test was less than 0.05. Results When we compared rectal tumors to non-involved rectal tissues, changes in expression levels of 171 genes were statistically significant in early-onset group and 151 genes in late-onset group. Further comparative gene expression analysis between early- and late-onset rectal tumors normalized to their matching non-involved tissues revealed that changes in expression of 65 genes were unique to early-onset rectal tumors with 16 genes being up- and 49 genes down-regulated using the cutoff criteria of expression levels difference >2 fold and p-value <0.01. At the pathway level, MAPK signaling was the most deregulated pathway in early-onset rectal tumors compared to PI3K-AKT signaling pathway being the most deregulated in late-onset rectal tumors.
