Background Traditionally, perforated diverticulitis has been managed with an open approach, with a Hartmann procedure or a colectomy with primary anastomosis. Minimally invasive surgery is associated with postoperative advantages in the elective setting and may show a benefit in the emergent setting. Objective The aim of this study was to compare postoperative outcomes of open vs minimally invasive approaches for emergent perforated diverticulitis. Design This was a retrospective review of the American College of Surgeons National Surgical Quality Improvement Program targeted colectomy database using propensity score matching. Settings Interventions were performed in hospitals participating in the national database. Patients Patients who underwent emergent colectomy from 2012 to 2017 were included. Procedures were divided into Hartmann procedure and primary anastomosis. Open vs minimally invasive groups were defined by intention to treat. Main outcome measures Outcomes measures included length of stay and overall morbidity and mortality. Results Of 130,616 patients, 7105 met inclusion criteria (4486 Hartmann procedure and 2619 primary anastomosis). A total of 1989 open Hartmann procedure cases were matched to 663 minimally invasive cases. The minimally invasive group underwent longer operations and had lower rates of respiratory failure. There were no differences in overall complications, mortality, length of stay, or home discharge. In the primary anastomosis group, 1027 cases were matched 1:1. The minimally invasive approach was associated with longer operative times, but reduced wound dehiscence, sepsis, bleeding, overall complications, and length of stay. No difference was detected in anastomotic leak, mortality, reoperation, or readmission rates. Limitations Limitations include retrospective nature, data loss, nonuniformity, selection bias, and coding errors. Conclusions Emergent minimally invasive primary anastomosis results in a shorter length of stay and decreased 30-day morbidity in comparison with open primary anastomosis for perforated diverticulitis. Emergent open and minimally invasive Hartmann procedures for perforated diverticulitis have comparable outcomes, perhaps because of a 40% conversion rate.

Abordaje abierto versus mnimamente invasivo para colectoma de emergencia en diverticulitis perforada ANTECEDENTES:Tradicionalmente, la diverticulitis perforada se ha tratado con un abordaje abierto, con un procedimiento de Hartmann o una colectomia con anastomosis primaria. La cirugia minimamente invasiva se asocia con ventajas posoperatorias en el escenario electivo y puede mostrar beneficio en el escenario emergente.OBJETIVO:El objetivo de este estudio fue comparar los resultados posoperatorios del abordaje abierto versus el minimamente invasivo para la diverticulitis perforada emergente.DISENO:Esta fue una revision retrospectiva de la base de datos de colectomia dirigida del Programa Nacional de Mejoramiento de la Calidad Quirurgica del Colegio Americano de Cirujanos utilizando el pareamiento por puntaje de propension.ESCENARIO:Las intervenciones se realizaron en los hospitales participantes en la base de datos nacional.PACIENTES:Se incluyeron pacientes que fueron sometidos a colectomia emergente de 2012 a 2017. Los procedimientos se dividieron en procedimiento de Hartmann y anastomosis primaria. Los grupos abierto versus minimamente invasivo se definieron por intencion de tratar.PRINCIPALES MEDIDAS DE RESULTADO:Las medidas de resultado incluyeron la duracion de la estancia, la morbilidad general y la mortalidad.RESULTADOS:De 130,616 pacientes, 7,105 cumplieron los criterios de inclusion (4,486 procedimiento de Hartmann y 2,619 anastomosis primaria). 1,989 casos abiertos de procedimientos de Hartmann se emparejaron con 663 casos minimamente invasivos. El grupo minimamente invasivo se sometio a operaciones mas prolongadas y tuvo tasas mas bajas de insuficiencia respiratoria. No hubo diferencias en las complicaciones generales, la mortalidad, la duracion de la estancia o el alta domiciliaria. En el grupo de anastomosis primaria, 1,027 casos se emparejaron 1: 1. El abordaje minimamente invasivo se asocio con tiempos quirurgicos mas prolongados, pero tambien con tasas reducidas de dehiscencia de herida, sepsis, sangrado, complicaciones generales y la duracion de la estancia. No se detectaron diferencias en las tasas de fuga anastomotica, mortalidad, reintervencion o reingreso.LIMITACIONES:Las limitaciones incluyen la naturaleza retrospectiva, perdida de datos, falta de uniformidad, sesgo de seleccion y errores de codificacion.CONCLUSIONES:La anastomosis primaria minimamente invasiva emergente resulta en una estancia mas corta y una disminucion de la morbilidad a los 30 dias en comparacion con la anastomosis primaria abierta para la diverticulitis perforada. El procedimiento de Hartmann abierto y minimamente invasivo de emergencia para la diverticulitis perforada tiene resultados comparables, quizas debido a una tasa de conversion del 40%.

Diverticular disease is a common problem where patients with diverticulosis have a 1–4 per cent risk of acute diverticulitis. Current guidelines recommend a colonoscopy after.the resolution of acute diverticulitis. The aim of this study was to evaluate the yield of significant findings on colonoscopy after an episode of diverticulitis. This is a retrospective analysis of patients who underwent colonoscopy after an episode of diverticulitis between November 2005 and August 2017 at three major teaching hospitals. Advanced adenomas were defined as adenomas ≥1 cm, serrated adenomas, and tubulovillous or villous adenomas. A total of 584 patients (298 males; 51%) underwent colonoscopy for a history of diverticulitis after resolution of acute symptoms. Colonoscopy was complete in 488 patients (84%). Among these 488 patients, 446 had diverticular disease, 31 had advanced adenomas, and four had adenocarcinomas. Colonoscopies were incomplete in 96 patients (16%). Forty-six of those patients underwent surgery. The overall incidence of advanced adenomas and adenocarcinomas was 32 (5.4%) and nine (1.5%), respectively. In our study, the prevalence of advanced adenomas and adenocarcinomas was relatively high compared with the average risk individuals. Our findings support that patients after an episode of diverticulitis should continue to get a colonoscopy.

BACKGROUND Hemorrhoids are common and affect mainly the young and middle-aged populations. Current guidelines recommend treating grade I and II hemorrhoids with office-based procedures. These therapies usually require multiple applications. Hemorrhoid energy therapy treats the hemorrhoids at 1 treatment session. OBJECTIVE The purpose of this study was to evaluate the safety and efficacy of hemorrhoid energy therapy. DESIGN This was a prospective pilot study evaluating patients with symptomatic grade I and II internal hemorrhoids. SETTINGS The study was conducted at a tertiary academic center. PATIENTS Patients over the age of 18 years with chronic, symptomatic grade I and II internal hemorrhoids who failed 2 weeks of conservative therapy were enrolled between July 2015 and January 2019. Exclusion criteria included patients with grade III or IV internal hemorrhoids, external hemorrhoids, nonhemorrhoidal GI bleeding, active proctitis, and IBD. INTERVENTIONS Hemorrhoid energy therapy was administered in clinic, and 2 postprocedure visits were completed. A pretreatment hemorrhoid symptom score was obtained from each patient. A visual analog score was assessed posttreatment. MAIN OUTCOME MEASURES The primary end point was to evaluate the effect of hemorrhoid energy therapy on hemorrhoid symptoms and its safety. The secondary end point was evaluation of postprocedural pain. RESULTS A total of 35 patients were enrolled. The mean duration of hemorrhoid symptoms was 3.3 ± 6.4 years, and rectal bleeding and hemorrhoidal prolapse were the most common symptoms. After the procedure, patient hemorrhoid symptom scores decreased from mean 5.5 to 1.4. The mean immediate postprocedural visual analog score was 2.4 ± 2.1 and decreased to

Sphincter-sparing repairs are commonly used to treat anal fistulas with significant muscle involvement.The current study evaluates the trends and efficacy of sphincter-sparing repairs and determines risk factors for fistula recurrence.A retrospective review was performed at 3 university-affiliated teaching hospitals.All 462 patients with cryptoglandular anal fistulas who underwent 573 sphincter-sparing repairs between 2005 and 2015 were included. Patients with Crohn's disease were excluded.The primary outcome was the rate of fistula healing defined as cessation of drainage with closure of the external opening. Risk factors for nonhealing were also analyzed.Five hundred three sphincter-sparing repairs were analyzed, whereas 70 were lost to follow-up. Two hundred twenty sphincter-sparing repairs (44%) resulted in healing, 283 (56%) resulted in nonhealing with a median follow-up of 9 (range, 1-125) months. The median time to fistula recurrence was 3 (range, 0-75) months with 79% and 91% of recurrences noted within 6 and 12 months. Patients treated with a dermal advancement flap, rectal advancement flap, or ligation of the intersphincteric tract procedure were less likely to have a recurrence than patients treated with a fistula plug or fibrin glue (p0.001). Over time, there was a significantly increased use of the ligation of the intersphincteric tract procedure (p0.001) and a significantly decreased use of fistula plugs and fibrin glue (p0.001); healing rates improved accordingly. There were no significant differences in healing rates with respect to patient demographics, comorbidities, or fistula characteristics.This study was limited by its retrospective design.Healing rates following sphincter-sparing repairs of cryptoglandular anal fistulas are modest, but have improved over time with the use of better surgical techniques. In this study, ligation of the intersphincteric fistula tract and flaps were superior to fistula plugs and fibrin glue; the former procedures are therefore favored.

Aim Sacral nerve stimulation has become a preferred method for the treatment of faecal incontinence in patients who fail conservative (non-operative) therapy. In previous small studies, sacral nerve stimulation has demonstrated improvement of faecal incontinence and quality of life in a majority of patients with low anterior resection syndrome. We evaluated the efficacy of sacral nerve stimulation in the treatment of low anterior resection syndrome, using a recently developed and validated low anterior resection syndrome instrument to quantify symptoms. Method A retrospective review of consecutive patients undergoing sacral nerve stimulation for the treatment of low anterior resection syndrome was performed. Procedures took place in the Division of Colon and Rectal Surgery at two academic tertiary medical centers. Pre and post treatment Cleveland Clinic Incontinence Scores and Low Anterior Resection Syndrome Scores were assessed. Results Twelve patients (50% men) suffering from low anterior resection syndrome with a mean age of 67.8 (±10.8) years underwent sacral nerve test stimulation. Ten patients (83%) proceeded to permanent implantation. Median time from anterior resection to stimulator implant was 16 (range, 5-108) months. At a median follow-up of 19.5 (range, 4-42) months, there were significant improvements in Cleveland Clinic Incontinence Scores and the Low Anterior Resection Syndrome Scores (p

Anal fistulas continue to be a problem for patients and surgeons alike despite scientific advances. While patient and anatomical characteristics are important to surgeons who are evaluating patients with anal fistulas, their development and persistence likely involves a multifaceted interaction of histological, microbiological, and molecular factors. Histological studies have shown that anal fistulas are variably epithelialized and are surrounded by dense collagen tissue with pockets of inflammatory cells. Yet, it remains unknown if or how histological differences impact fistula healing. The presence of a perianal abscess that contains gut flora commonly leads to the development of anal fistula. This implies a microbiological component, but bacteria are infrequently found in chronic fistulas. Recent work has shown an increased expression of proinflammatory cytokines and epithelial to mesenchymal cell transition in both cryptoglandular and Crohn's perianal fistulas. This suggests that molecular mechanisms may also play a role in both fistula development and persistence. The aim of this study was to examine the histological, microbiological, molecular, and host factors that contribute to the development and persistence of anal fistulas.

AIM Frailty is defined as a decrease in physiological reserve with increased risk of morbidity following significant physiological stressors. This study examines the predictive power of the five-item modified frailty index (5-mFI) in predicting outcomes in colorectal surgery patients. METHODS The American College of Surgeons National Surgical Quality Improvement Program Database was queried from 2011 to 2016 to determine the predictive power of 5-mFI in patients who had colorectal surgery. RESULTS Of 295 490 patients, 45.8% had a score of 0, 36.2% had a score of 1 and 18% had a score of ≥ 2. On univariate analysis, frailer patients had significantly greater incidences for overall morbidity, serious morbidity, mortality, prolonged length of hospital stay, discharge to a facility other than home, reoperation and unplanned readmission. These findings were consistent on multivariate analysis where the frailest patients had greater odds of postoperative overall morbidity (OR 1.39; 95% CI 1.35-1.43), serious morbidity (OR 1.39; 95% CI 1.33-1.45), mortality (OR 2.00; 95% CI 1.87-2.14), prolonged length of hospital stay (OR 1.24; 95% CI 1.20-1.27), discharge destination to a facility other than home (OR 2.80; 95% CI 2.70-2.90), reoperation (OR 1.17; 95% CI 1.11-1.23) and unplanned readmission (OR 1.31; 95% CI 1.26-1.36). Weighted kappa statistics showed strong agreement between the 5-mFI and 11-mFI (kappa = 0.987, P

BACKGROUND The rates of recurrent prolapse after perineal proctectomy vary widely in the literature, with incidences ranging between 0% and 50%. The Thiersch procedure, first described in 1891 for the treatment of rectal prolapse, involves encircling the anus with a foreign material with the goal of confining the prolapsing rectum above the anus. The Bio-Thiersch procedure uses biological mesh for anal encirclement and can be used as an adjunct to perineal proctectomy for rectal prolapse to reduce recurrence. OBJECTIVE The aim of this study was to evaluate the Bio-Thiersch procedure as an adjunct to perineal proctectomy and its impact on recurrence compared with perineal proctectomy alone. DESIGN A retrospective review of consecutive patients undergoing perineal proctectomy with and without Bio-Thiersch was performed. SETTINGS Procedures took place in the Division of Colon and Rectal Surgery at a tertiary academic teaching hospital. PATIENTS Patients who had undergone perineal proctectomy and those who received perineal proctectomy with Bio-Thiersch were evaluated and compared. INTERVENTIONS All of the patients with rectal prolapse received perineal proctectomy with levatorplasty, and a proportion of those patients had a Bio-Thiersch placed as an adjunct. MAIN OUTCOME MEASURES The incidence of recurrent rectal prolapse after perineal proctectomy alone or perineal proctectomy with Bio-Thiersch was documented. RESULTS Sixty-two patients underwent perineal proctectomy (8 had a previous prolapse procedure), and 25 patients underwent perineal proctectomy with Bio-Thiersch (12 had a previous prolapse procedure). Patients who received perineal proctectomy with Bio-Thiersch had a lower rate of recurrent rectal prolapse (p < 0.05) despite a higher proportion of them having had a previous prolapse procedure (p < 0.01). Perineal proctectomy with Bio-Thiersch had a lower recurrence over time versus perineal proctectomy alone (p < 0.05). LIMITATIONS This study was limited by nature of being a retrospective review. CONCLUSIONS Bio-Thiersch as an adjunct to perineal proctectomy may reduce the risk for recurrent rectal prolapse and can be particularly effective in patients with a history of previous failed prolapse procedures.

Fistula between an ileal pouch and the vagina, anus, or perineum is an uncommon complication of ileal pouch-anal anastomosis and is a cause of considerable morbidity. Its optimal management has not been determined because of its low incidence. The aim of this study was to review the outcomes of patients who presented with symptomatic ileal pouch-associated fistulas after restorative proctocolectomy (RPC) and to present a diagnostic and treatment algorithm.Retrospective review of patients treated for symptomatic ileal pouch-associated fistulas after RPC from 1989 to 2011.Twenty-five patients (14 men, mean age 40 years) were presented with symptomatic ileal pouch-associated fistulas. Median time to pouch fistula following RPC was 6.9 years (range 1 month-20 years). Fistulas were classified as pouch-anal (n = 12, 48 %), pouch-vaginal (n = 7, 28 %), complex (n = 4, 16 %), and pouch-perineal (n = 2, 8 %). Etiology included Crohn's disease (n = 15, 60 %), cryptoglandular (n = 6, 24 %), and anastomotic failure (n = 4, 16 %). Each patient underwent an average of 2.8 local procedures or repairs. Overall healing rate was 64 % at a median follow-up of 29 (range 2-108) months. None of the complex fistulas were healed. Postoperative pelvic sepsis, fecal diversion, anti-tumor necrosis factor therapy, and fistula etiology did not significantly impact fistula healing. Three patients required pouch excision with end ileostomy.Operative treatment of pouch fistulas after RPC resulted in complete healing in 64 % of patients following a stepwise diagnostic and therapeutic approach.

Transanal endoscopic microsurgery has gained increasing popularity as a treatment alternative for early stage rectal neoplasms. With continued advances in technique and experience, more proximal rectal tumors are being surgically managed by using transanal endoscopic microsurgery with an intraperitoneal anastomosis.The purpose of this study was to review the outcomes of patients who have undergone intraperitoneal anastomosis with the use of the transanal endoscopic microsurgery technique.A prospective, single-surgeon database documented 445 consecutive patients undergoing transanal endoscopic microsurgery from October 1, 1996 through January 1, 2012. We retrospectively reviewed information from all patients who underwent transanal endoscopic microsurgery with an intraperitoneal anastomosis in this prospective database.All procedures took place in an inpatient hospital setting.All patients satisfied workup criteria to undergo surgery for rectal neoplasm.All patients underwent transanal endoscopic microsurgery for rectal neoplasm.Size and pathology of lesion, length of procedure, hospital stay, estimated blood loss, margin status, and complications were the outcomes measured.Twenty-eight patients who underwent transanal endoscopic microsurgery had definitively documented intraperitoneal entry and anastomosis. Median follow-up was 12 months (range, 0.5-111 months). There were no operative mortalities. Procedure-related complications included urinary retention (11%), fever (11%), and fecal seepage (4%). Four patients (14%) had positive margins on final pathology. One patient (3%) required abdominal exploration for an anastomotic leak but did not require diversion.Although this study analyzes prospectively collected data, it is nonetheless a retrospective analysis that can introduce bias. Because this is a single-center study with a relatively homogenous population, the results may not be generalizable. Our sample size may also be underpowered to detect clinically significant outcomes.Transanal endoscopic microsurgery with intraperitoneal anastomosis can be safely performed without fecal diversion by experienced surgeons.

Sacrocolpopexy with rectopexy is advocated for combined rectal and vaginal prolapse, but limited outcome data have been reported.The purpose of this study was to evaluate the indications and outcomes of sacrocolpopexy and rectopexy by comparing pre- and postoperative function and quality of life.A retrospective review of prospectively collected data was performed of all patients undergoing sacrocolpopexy and rectopexy at our institution from 2004 to 2011.Preoperatively, all patients underwent physiology testing and completed 4 validated questionnaires assessing bowel symptom severity and associated quality of life. Patients completed the same questionnaires in 2012.A total of 110 women (median age, 55 years; range, 28-88) underwent a sacrocolpopexy and rectopexy, 33 with concomitant hysterectomy. All patients had rectal prolapse (n = 96) or rectal intussusception (n = 14), and each also had either enterocele (n = 86) or vaginal prolapse (n = 48). Rectal prolapse with enterocele was the most common presentation (n = 75). Previous surgery included rectal prolapse repair (21%) and hysterectomy (57%). Complications included presacral bleeding (n = 2), ureteral injury (n = 2), wound infection (n = 8), and pulmonary embolism (n = 2). There were no mortalities. Fifty-two patients completed the follow-up questionnaires, with a median follow-up of 29 (range, 4-90) months, and preoperative surveys were available in 30 of these patients. Preoperatively, 93% reported constipation; 82% reported resolution or improvement postoperatively. Constipation severity, measured with the Patient Assessment of Constipation Symptom Questionnaire, demonstrated improvement (1.86-1.17; p0.001). Fecal incontinence severity scores (Fecal Incontinence Severity Index) improved (39-24; p0.01), and 82% of incontinent patients reported cure or improvement. Quality-of-life scores also improved significantly. No patient developed recurrent rectal prolapse.This was a retrospective review, and the response rate to questionnaires was limited.Sacrocolpopexy and rectopexy for combined middle and posterior compartment prolapse is a safe procedure, with low risk for recurrence, and improves bowel function and quality of life in most patients.

The ligation of the intersphincteric fistula tract procedure has been reported to have high cure rates, with minimal impairment of continence.The aim of this study was to evaluate the success rates and functional outcome after the ligation of the intersphincteric fistula tract procedure.This study was performed as a retrospective review.The study was conducted at the Division of Colon and Rectal Surgery, University of Minnesota and at affiliated hospitals in Minneapolis and St. Paul, Minnesota, between March 2007 and September 2011.Ninety-three patients with transsphincteric cryptoglandular anal fistula were included.Ligation of the intersphincteric fistula tract procedure was performed.Failure was defined as persistent or recurrent drainage, air leakage from a patent external opening, or intersphincteric incision or reoperation for recurrent fistula. Success was defined as healing of the external fistula opening and intersphincteric incision. Patients were followed up with a questionnaire to assess the recurrence rate and the Wexner incontinence score.The median follow-up time for was 19 months (range, 4-55). Thirty patients (32%) had a history of previous surgery for their fistula. The success rate of fistula healing was 40% after the first ligation of the intersphincteric fistula tract procedure. When including patients with repeat ligation of the intersphincteric fistula tract and subsequent intersphincteric fistulotomy after ligation of the intersphincteric fistula tract repair, the success rates were 47% and 57%. Patients with successful fistula closure reported a mean Cleveland Clinic Florida Fecal Incontinence score of 1.0 (SD 2.3). No predictor for successful fistula closure was found.Retrospective design, limited accuracy of diagnosing fistula failure, and lack of baseline continence were limitations of this study.The present study indicates that the ligation of the intersphincteric fistula tract procedure for transsphincteric fistulas has a significant risk for failure but good functional outcome in patients with no recurrence.

The aim of this was to define 30-day outcomes of patients treated with colectomy and en bloc pancreatectomy for invasive colon cancer.ACS NSQIP was used to identify patients who underwent colectomy and pancreatectomy concomitantly (n = 65) for colon carcinoma. Patients with en bloc pancreatectomy were compared to a propensity score-matched control group for 30-day outcomes.Sixteen patients underwent a pancreaticoduodenectomy with colectomy and 49 patients underwent a distal pancreatectomy with colectomy. There were 195 matched control patients. En bloc pancreatectomy (Whipple vs. distal pancreatectomy vs. control) patients had longer OR times (390 vs. 265 vs.137 min) and length of postoperative stay (12 vs. 10 vs. 6 days). The frequency of pulmonary complications (31.3% vs. 36.7% vs. 3.6%), blood transfusions (2.9 vs. 1.7 vs. 0.3 U), wound dehiscence, (18.8% vs. 6.12% vs.0.5%) and surgical site infection (43.5% vs. 34.7% vs.14.9%) were substantially higher in the pancreatectomy group (p0.05). There were no statistically significant differences in 30-day mortality between the pancreatectomy group and the control group (6.3% vs. 0% vs. 1.5% p = 0.25)Perioperative outcomes with en bloc pancreatectomy and colectomy include increased pulmonary complications, blood transfusions, wound complications, and length of stay compared to patients treated with colectomy alone for colon cancer.

Aim Background Obesity rates are rapidly growing in the developed world. While upper gastrointestinal disturbances and urinary incontinence are independently associated with obesity, the relationship between obesity and defecatory dysfunction is less well defined. Objectives To summarize the literature on faecal incontinence, diarrhoea and constipation in obese patients and its effects of bariatric surgery. Method Search strategy A Medline search was carried out on articles published from January 1966 to March 2010. Selection criteria Original articles on adult obese or morbidly obese patients were identified, including results following bariatric surgery that reported faecal incontinence, diarrhoea or constipation. Other forms of pelvic floor dysfunction were excluded. Main outcome measures included faecal incontinence, diarrhoea and constipation rates and their severity in obese patients and following bariatric surgery. Results Twenty studies reported defecatory outcomes in obese patients (n = 14) and after bariatric surgery (n = 6). While constipation rates were similar, the rates of faecal incontinence and diarrhoea were higher in obese patients compared with non-obese patients. The exact rates of these conditions, and the correlations between body mass index (BMI) and faecal incontinence, diarrhoea and constipation, were not clear. Faecal incontinence improved after Roux-en-Y gastric bypass in studies with preoperative data. The effects of bariatric surgery on diarrhoea were unclear. Conclusion Few studies have assessed the correlations between obesity and defecatory function and the effect of bariatric surgery. Studies were often not well controlled and used non-uniform instruments to assess bowel function. Obesity appears to be correlated with higher rates of faecal incontinence and diarrhoea. The effects of bariatric surgery on these conditions are not well defined. Well-controlled studies correlating outcome with physiological pelvic floor function are needed.

This study investigates the association between endoanal ultrasonography and anorectal manometry in relation to anal incontinence after primary repair of obstetric sphincter injury in primiparous, premenopausal women.The study population of this nested case-control study comprised 108 women who had previously been part of a randomized controlled trial comparing immediate with delayed primary repair of obstetric sphincter injuries, and who had been evaluated by anorectal manometry and endoanal ultrasound 1 year after their repair. Twenty cases and 88 controls were defined. Cases were defined as having a score greater than 2 on the Pescatori incontinence scale. Controls had a score of 2 or less. Ten obstetric, 9 ultrasonographic, and 7 manometric variables were studied.Of the manometric variables, volume of first sensation and volume of first urge proved to be associated with anal incontinence at univariate statistical analysis. Volume of first sensation remained independently associated with anal incontinence after multivariate analysis. In addition, age, degree of tear, duration of second stage of labor, and a distal scar at ultrasound proved to be independently associated with anal incontinence.Impaired rectal sensation at anorectal manometry and a distal scar at endoanal ultrasonography are associated with anal incontinence 1 year after primary sphincter repair in primiparous women. Additional studies need to evaluate whether these findings are associated with increased risk of anal incontinence in women that are continent 1 year after primary repair.

Aim Surgical repair of recto-vaginal fistula (RVF) in Crohn’s disease (CD) has been associated with high rates of failure. The aim of this study was to compare the outcome in patients with CD who underwent RVF surgery with or without infliximab infusion. Method A retrospective review was carried out of 51 consecutive patients with CD treated for a symptomatic RVF between March 1998 and December 2004. Results Fifty-one patients (mean age 39 years) underwent 65 procedures, including seton drainage (n = 35), advancement flap (n = 8), fibrin glue injection (n = 8), transperineal repair (n = 6), collagen plug placement (n = 4) and bulbocavernosus flap (n = 4). All patients were on medical treatment at the time of surgery and 26 patients had received preoperative infliximab treatment (minimum of three infusions, 5 mg/kg). Ten patients underwent preoperative diversion. At a mean follow up of 38.6 months, 27 fistulas (53%) had healed and 24 (47%) had recurred. Fistula healing occurred in 60% of patients treated with preoperative diversion, whereas 51% of nondiverted repairs were successful. Neither active proctitis nor infliximab therapy significantly affected fistula healing. Fourteen (27%) patients eventually required proctectomy. Conclusion RVF in CD is difficult to treat. Failure rates are significant despite repeated surgical interventions and concomitant medical treatment.

Purpose This study was designed to analyze the incidence, management, and outcome of pouch sinuses after ileal pouch-anal anastomosis at one institution. Methods We identified 282 ileal pouch-anal anastomosis patients between 1992 and 2002 who had a pouchogram before planned ileostomy closure. The management and outcome of patients with pouchograms revealing pouch sinuses were reviewed. Results Twenty-two patients (7.8 percent) had a pouch sinus at pouchogram. Nineteen patients were observed and underwent repeat pouchogram. Of these, ten had sinus resolution (mean, 3.6 months) and underwent successful ileostomy closure. Eight patients underwent examination under anesthesia +/- sinus debridement. Six of these patients had subsequent pouchograms with five showing sinus resolution. The patient without resolution was not reversed. Of the eight patients who underwent examination under anesthesia +/- debridement, seven underwent ileostomy closure (mean, 4.9 months), with healing in six and pelvic sepsis in one. Four patients underwent successful ileostomy takedown despite persistent sinus. Overall, 21 of the 22 pouch sinus patients underwent ileostomy closure and only 1 had postoperative pelvic sepsis. Conclusions Pouch sinuses after ileal pouch-anal anastomosis with ileostomy are uncommon. Most heal within six months. The majority of patients with sinuses eventually undergo successful ileostomy closure. Pelvic septic complications are rare but can occur despite sinus healing on pouchogram.

Anal fistulas that involve a significant amount of sphincter may be difficult to treat without compromising continence function. In this study, we evaluated our experience with the Surgisis anal fistula plug, which was recently reported to be successful in80 percent of patients with complex fistulas.We retrospectively collected patient and fistula characteristics, procedure details, and follow-up information for all patients treated with the anal fistula plug at our institution from January 2006 through April 2007. The outcome was considered successful if the external opening was closed and if the patient had no drainage at the last follow-up. Using multivariate statistics, we analyzed the relationship between anal fistula plug success and several key variables.From January 2006 through April 2007, 47 patients with 49 complex anal fistulas underwent 64 anal fistula plug procedures. The median follow-up time for patients who were considered healed was 6.5 (range, 3-11) months. The success rate was 31 percent per procedure and 43 percent per patient. An increased amount of external sphincter involvement was associated with a higher failure rate (P0.05).In our early experience with the anal fistula plug, 43 percent of patients with complex anal fistulas were successfully treated. Patients with less external sphincter involvement were more likely to heal.

We describe the relationship between anorectal manometry, fecal incontinence severity, and findings at endoanal ultrasound.A total of 351 women completed the Fecal Incontinence Severity Index, underwent anorectal manometry, and endoanal ultrasound. Severity index and manometry pressures in 203 women with intact sphincters on ultrasound were compared with pressures in 148 women with sphincter defects. Relationships between resting and squeeze pressures, severity index, and size of sphincter defects were evaluated.Mean severity index in patients with and without sphincter defect was 35.7 vs. 36.7 (not significant). Worsening index correlated with worsening mean and maximum resting pressure (P0.0001). Differences were observed in mean and maximum resting pressure between the patients with and without sphincter defects (26.6 vs. 37.2, P0.0001; 39.4 vs. 51.7, P0.001). Resting pressures correlated with the sizes of defect (P0.0001).Patients with and without sphincter defects had similar severity scores, but patients with defects had a significant decrease in resting pressures. Patients with larger sphincter defects had lower severity scores and resting pressures. Until a manometry cutoff can be set to discriminate between absence and presence of defects, both manometry and ultrasound should be offered to patients with history of anal trauma.

Despite its widespread use, the role of local excision for early rectal cancer as a curative therapy remains controversial. Studies are often plagued with low patient numbers, limited follow-up, or heterogeneous populations. In addition, problems with inaccurate staging, inadequate resection margins, and patient selection have limited the ability to interpret, compare, and generalize results. This article will focus on reported outcomes of local excision for early rectal cancer and discuss suggested guidelines.

Difficulties with bowel function are common and may be due to several causes including slow colonic transit and obstructed defecation. The anatomical and pathophysiological changes associated with these conditions are varying, often incompletely understood, and in many cases have limited treatment outcomes. Patients present with variable complaints and have previously tried a plethora of over-the-counter medications in an effort to relieve their symptoms. Physicians need an organized approach to manage these patients optimally. Improvements over the past few years in our understanding of the complex process of defecation, along with the increasing use of radiological and anorectal physiology studies, have led to improved treatment results.

BACKGROUND Overall, the incidence of colorectal cancer appears to be stable or diminishing. However, based on our practice pattern, we observed that the incidence of rectal cancer in patients under 40 is increasing and may be associated with a prominence of signet-ring cell histology. OBJECTIVE The aim of this study was to verify the rising trend in rectal cancer in patients under 40 and describe the histology prominent in that cohort. DESIGN This is a retrospective cohort study. SETTING AND PATIENTS We performed a retrospective cohort study of all patients diagnosed with rectal adenocarcinoma from 1980 to 2010 using the Surveillance, Epidemiology, and End Results cancer registry. MAIN OUTCOME MEASURES Rectal cancer incidence, histology, and associated staging characteristics were the primary outcomes measured. RESULTS Although the incidence of rectal cancer for all ages remained stable from 1980 to 2010, we observed an annual percent change of +3.6% in the incidence of rectal cancer in patients under 40. The prevalence of signet cell histology in patients under 40 was significantly greater than in patients over 40 (3% vs 0.87%, p < 0.01). A multivariate regression analysis revealed an adjusted odds ratio of 3.6 (95% CI, 2.6-5.1) for signet cell histology in rectal adenocarcinoma under age 40. Signet cell histology was also significantly associated with a more advanced stage at presentation, poorly differentiated tumor grade, and worse prognosis compared with mucinous and nonmucinous rectal adenocarcinoma. LIMITATIONS The study was limited by its retrospective nature and the information available in the Surveillance, Epidemiology, and End Results database. CONCLUSIONS Despite a stable incidence of rectal cancer for all ages, the incidence in patients under 40 has quadrupled since 1980, and cancers in this group are 3.6 times more likely to have signet cell histology. Given the worse outcomes associated with signet cell histology, these data highlight a need for thorough evaluation of young patients with rectal symptoms.

Ziel dieser Studie war es, die Pravalenz von Genitalprolaps-Operationen und Harninkontinenz bei Patientinnen, die wegen eines Rektumprolaps operiert worden waren, im Vergleich zu einer entsprechenden Kontrollgruppe ohne Rektumprolaps zu untersuchen. 52 Patientinnen mit Rektumprolaps-Operationen in der Vorgeschichte sowie 200 willkurlich ausgewahlte, alters- und geschlechtsangepasste Kontrollpersonen ohne Rektumprolaps erhielten einen ausfuhrlichen Gesundheitsfragebogen. Die Rucklaufquote betrug in der Patientinnengruppe 48 von 52 (92%) und in der Kontrollgruppe 165 von 200 (82%). Ein Rektumprolaps war mit einem gesteigerten Operationsrisiko wegen eines Uterusprolaps (Odds-Ratio = 3,1; 95%-Konfidenzintervall = 1,4–6,9) und eines Vaginalprolaps (Odds-Ratio = 3,2; 95%-Konfidenzintervall = 1,3–7,8) assoziiert. Das mittlere Alter bei einer Hysterektomie wegen Uterusprolaps betrug 54,7 Jahre in der Patientinnengruppe, verglichen mit 62,6 Jahren in der Kontrollgruppe (p < 0,01). Das mittlere Alter bei Vaginalprolaps-Operation betrug 60,2 Jahre in der Patientinnengruppe, verglichen mit 66,6 Jahren in der Kontrollgruppe (p < 0,05). Es fanden sich keine signifikanten Unterschiede zwischen den Gruppen bezuglich einer hoheren Pravalenz oder des Alters beim ersten Auftreten einer Harninkontinenz. Die Ergebnisse zeigen einen starken Zusammenhang zwischen einer rektalen und genitalen Prolapsoperation. Dies legt nahe, dass der Diagnose eines Rektumprolaps, der operiert werden soll, eine multidisziplinare Beckenboden-Untersuchung folgen muss.

Data supporting an increased risk of colorectal cancer in patients with Crohn’s colitis are inconsistent. Despite this, clinical recommendations regarding colonoscopic screening and surveillance for patients with Crohn’s colitis are extrapolated from chronic ulcerative colitis protocols. The primary aim of our study was to determine the incidence of dysplasia and carcinoma in pathology specimens of patients undergoing segmental or total colectomy for Crohn’s disease of the large bowel. In addition, we sought to identify risk factors associated with the development of dysplasia and carcinoma. We performed a retrospective review of all patients operated on at our institution for Crohn’s colitis between January 1992 and May 2004. Data were retrieved from patient charts, operative notes, and pathology reports. Logistic regression was used to model the probability of having dysplasia or adenocarcinoma. Two hundred twenty-two patients (138 females) who underwent surgical resection for the treatment of Crohn’s colitis were included in the study. Mean age at surgery was 41 (range, 15–82) years and the mean duration of disease was 10 (range, 0–53) years. There were five cases of dysplasia (2.3 percent) and six cases of adenocarcinoma (2.7 percent). Three patients with dysplasia and one with adenocarcinoma were diagnosed on preoperative colonoscopy; while the other cases were discovered incidentally on pathologic examination of resected specimens. Factors associated with the presence of dysplasia or adenocarcinoma included older age at diagnosis (38.2 vs. 30.3 years, P = 0.02), longer disease duration (16.0 vs. 10.1 years, P = 0.05), and disease extent (90 percent extensive vs. 59 percent limited, P = 0.05). Patients with severe Crohn’s colitis requiring surgery are at significant risk for developing dysplasia and adenocarcinoma, particularly when diagnosed at an older age, after longer disease duration, and with more extensive colon involvement.

Pudendal nerve terminal motor latency testing has been used to test for pudendal neuropathy, but its value remains controversial. We sought to clarify the relationship of pudendal nerve terminal motor latency to sphincter pressure and level of continence in a cohort of patients with intact anal sphincters and normal pelvic floor anatomy. We reviewed 1,404 consecutive patients who were evaluated at our pelvic floor laboratory for fecal incontinence. From this group, 83 patients had intact anal sphincters on ultrasound and did not have internal or external rectal prolapse during defecography. These patients were evaluated by pudendal nerve terminal motor latency testing, a standardized questionnaire, and anorectal manometry, which measured resting and squeeze anal pressures. Incontinence scores were calculated by using the American Medical Systems Fecal Incontinence Score. Values were compared by using the Fisher’s exact test and Wilcoxon’s rank-sum test; and significance was assigned at the P < 0.05 level. 1) Using a 2.2-ms threshold, 28 percent of patients had prolonged pudendal nerve terminal motor latency unilaterally and 12 percent bilaterally. 2) At a 2.4-ms threshold, 18 percent of patients had prolonged pudendal nerve terminal motor latency unilaterally and 8 percent bilaterally. 3) Bilaterally prolonged pudendal nerve terminal motor latency was significantly associated with decreased maximum mean resting pressure and increased Fecal Incontinence Score, but not decreased maximum mean squeeze pressure, at both 2.2-ms and 2.4-ms thresholds. 4) Unilaterally prolonged pudendal nerve terminal motor latency was not associated with maximum mean resting pressure, maximum mean squeeze pressure, or fecal incontinence score at either threshold. The majority of incontinent patients with intact sphincters have normal pudendal nerve terminal motor latency. Bilaterally but not unilaterally prolonged pudendal nerve terminal motor latency is associated with poorer function and physiology in the incontinent patient with an intact sphincter.

Recurrent rectal prolapse is an unresolved problem and the optimal treatment is debated. This study was designed to review patterns of care and outcomes in a large cohort of patients after surgery for recurrent prolapse. From 685 patients who underwent operative repair for full-thickness external rectal prolapse, we identified 78 patients (70 females; mean age, 66.9 years) who underwent surgery for recurrence. We reviewed the subsequent management and outcomes for these 78 patients. Mean interval to their first recurrence was 33 (range, 1–168) months. There were significantly more re-recurrences after reoperation using a perineal procedure (19/51) compared with an abdominal procedure (4/27) for their recurrent rectal prolapse (P = 0.03) at a mean follow-up of nine (range, 1–82) months. Patients undergoing abdominal repair of recurrence were significantly younger than those who underwent perineal repair (mean age, 58.5 vs. 71.5 years; P < 0.01); however, there was nosignificant difference between the two groups with regard to the American Society of Anesthesiologists classification (P = 0.89). Eighteen patients had surgery for a second recurrence, with perineal repairs associated with higher failure rates (50 vs. 8 percent; P = 0.07). Finally, when combining all repairs, the abdominal approach continued to have significantly lower recurrence rates (39 vs. 13 percent; P < 0.01). The re-recurrence rate after surgery for recurrent rectal prolapse is high, even at a relatively short follow-up interval. Our data suggest that abdominal repair of recurrent rectal prolapse should be undertaken if the patient's risk profile permits this approach.

This study was designed to evaluate rectocele repair using collagen mesh. 32 female patients underwent surgical repair using collagen mesh. Outcome was assessed in 29 patients and preoperative assessment included standardized questionnaire, clinical examination, and defecography. At the six-month follow-up, patients answered a standardized questionnaire and underwent clinical examination. At the 12-month follow-up, patients answered a standardized questionnaire, underwent clinical examination, and defecography. Preoperatively, 26 patients had a Stage II and 3 patients had a Stage III rectocele. At the 6-month follow-up, five patients had rectocele ≥ Stage II (P < 0.001) and at the 12-month follow-up, seven patients had rectocele ≥ Stage II (P < 0.001) at clinical examination. At the preoperative defecography, all patients presented a rectocele. At the 12-month defecography, 14 patients had no rectocele (P < 0.001) and 15 had a rectocele. At the six-month follow-up, there was a significant decrease in rectal emptying difficulties, need of digital support of the posterior vaginal wall at defecation, and defecation frequency. At the 12-month follow-up, symptom improvement remained, but was less pronounced. Rectocele repair using collagen mesh improved anatomic support, but there is a substantial risk for recurrence with unsatisfactory anatomic and functional outcome one year after surgery. Rectocele repair using mesh was not associated with an increased risk of dyspareunia. Rectocele repair using biomaterial mesh reinforcement needs further evaluation before adopted into clinical practice.

BACKGROUND Rectal prolapse occurs primarily in older patients who often have significant comorbidities. With the aging population, increasing numbers of elderly patients are presenting with rectal prolapse. The perineal approach is preferred for these patients because it involves less perioperative risk than an abdominal procedure, but the outcomes of this procedure in elderly patients are unknown. OBJECTIVE The aim of this study was to examine whether clinical outcomes after perineal proctectomy are similar among elderly patients versus patients of younger age. DESIGN This study was a retrospective review. SETTING This study was conducted in mixed academic and private practice; the operations were performed at 16 hospitals. PATIENTS Patients who had perineal proctectomy for rectal prolapse from 1994 to 2012 were grouped according to age

Background Injectable bulking treatment for fecal incontinence (FI) is intended to expand tissue in the anal canal and prevent fecal leakage. Use of injectable bulking agents is increasing because it can be performed in an outpatient setting and with low risk for morbidity. This study evaluated the long-term (36-month) clinical effectiveness and safety of injection of non-animal stabilized hyaluronic acid/dextranomer (NASHA Dx) on FI symptoms. Methods In a prospective multicenter trial, 136 patients with FI received the NASHA Dx bulking agent. Treatment success defined as a reduction in number of FI episodes by 50% or more compared with baseline (Responder50). Change from baseline in Cleveland Clinic Florida Fecal Incontinence Score (CCFIS) and Fecal Incontinence Quality of Life Scale (FIQL), and adverse events were also evaluated. Key Results Successful decrease in symptoms was achieved in 52% of patients at 6 months and this was sustained at 12 months (57%) and 36 months (52%). Mean CCFIS decreased from 14 at baseline to 11 at 36 months (p

Endoanal ultrasound is essential in the assessment of patients suffering from fecal incontinence. The procedure can assist in selecting patients for the appropriate treatment modality and the procedure is also used in the evaluation of outcomes after treatment. Endoanal ultrasound can identify patients that may benefit from surgical sphincter repair with overlapping sphincteroplasty and the technique also plays an important role in selecting patients for other treatment options, including the artificial anal sphincter, sacral nerve stimulation, and injectable biomaterials.

The most common surgical treatment for fecal incontinence is sphincteroplasty, but this treatment option requires a localized anatomic sphincter injury and outcomes vary and tend to deteriorate with time. Other surgical techniques have therefore been developed. Postanal repair was designed to restore the anorectal angle with muscle plication of the posterior aspect of the anal canal. Initial improvement rates are acceptable, but only a small proportion of patients reports complete alleviation of symptoms and outcomes deteriorate with time. Suboptimal long-term outcome has lead to decreased use of the procedure. Electrostimulation of a transposed gracilis muscle around the anal canal can yield excellent results in selected patients. Complication rates are high when performed in nonspecialist centers, and the technique is currently not approved in the USA. Artificial bowel sphincter can restore acceptable anal continence and is used for treatment of end-stage fecal incontinence. A problematic high incidence of infection and erosion problems has been reported in some studies, which can hopefully be improved with a more stringent sterile protocol and centralization of the procedure to select specialist centers.

PURPOSE: Radical surgery of rectal cancer is associated with significant morbidity, and some patients with low-lying lesions must accept a permanent colostomy. Several studies have suggested satisfactory tumor control after local excision of early rectal cancer. The purpose of this study was to compare recurrence and survival rates after treating early rectal cancers with local excision and radical surgery. METHODS: One hundred eight patients with T1 and T2 rectal adenocarcinomas treated by transanal excision were compared with 153 patients with T1N0 and T2N0 rectal adenocarcinomas treated with radical surgery. Neither group received adjuvant chemoradiation. Mean follow-up time was 4.4 years after local excision and 4.8 years after radical surgery. RESULTS: The estimated five-year local recurrence rate was 28 percent (18 percent for T1 tumors and 47 percent for T2 tumors) after local excision and 4 percent (none for T1 tumors and 6 percent for T2 tumors) after radical surgery. Overall recurrence was also higher after local excision (21 percent for T1 tumors and 47 percent for T2 tumors) than after radical surgery (9 percent for T1 tumors and 16 percent for T2 tumors). Twenty-four of 27 patients with recurrence after local excision underwent salvage surgery. The estimated five-year overall survival rate was 69 percent after local excision (72 percent for T1 tumors and 65 percent after T2 tumors) and 82 percent after radical surgery (80 percent for T1 tumors and 81 percent for T2 tumors). Differences in survival rate between local excision and radical surgery were statistically significant in patients with T2 tumors. CONCLUSIONS: Local excision of early rectal cancer carries a high risk of local recurrence. Salvage surgery is possible in most patients with local recurrence, but may be effective only in patients with T1 tumors. When compared with radical surgery, local excision may compromise overall survival in patients with T2 rectal cancers.

Endoanal ultrasonography has become an important tool in the evaluation of patients with anal incontinence. However, the extent of anterior defects is sometimes difficult to quantitate during endoanal ultrasonography.This study was designed to evaluate perineal body measurement during endoanal ultrasonography in assessing patients with obstetric anal sphincter injuries.Forty-two patients with anal incontinence because of obstetric sphincter injuries and 13 asymptomatic subjects were investigated with endoanal ultrasonography. Sphincter muscle thickness, sphincter defects, and perineal body were measured. Perineal body measurement was performed by inserting a finger, held gently against the posterior vaginal wall, into the vagina and measuring the distance between the inner surface of the internal sphincter and the ultrasonographic reflection of the finger.All patients had anterior sphincter lesions of varying extent. Mean size of internal sphincter lesions was 146 degrees, and mean size of external sphincter lesions was 107 degrees (P0.001). Perineal body measurement was performed without difficulty in all patients and subjects. Perineal body measurement (mean +/- standard deviation) was 6 +/- 2 mm in patients and 12 +/- 3 mm in asymptomatic subjects (P0.001). Ninety-three percent of patients had perineal body measurementor = 10 mm, and 70 percent of asymptomatic subjects had perineal body measurement10 mm. Digital delineation of the perineal body during endoanal ultrasonography improved the visualization of sphincter lesions in 74 percent of patients.Digital delineation of the perineal body during endoanal ultrasonography improved the visualization of sphincter lesions in the majority of patients. Perineal body measurement is performed without difficulty and is a good predictor of anterior sphincter lesions. Use of this technique improves visualization of sphincter lesions.

Preoperative chemoradiation therapy in patients with rectal cancer results in pathologic complete response in approximately 10% to 30% of patients. Accurate predictive factors for obtaining pathologic complete response would likely influence the selection of patients best treated by chemoradiation therapy as the primary treatment without radical surgery.The aim of this study was to evaluate the impact of tumor size, stage, location, circumferential extent, patient characteristics, and pretreatment CEA levels on the development of pathologic complete response after chemoradiation therapy.This study is a retrospective review.Five hundred thirty patients treated with preoperative chemoradiation therapy and radical surgery for rectal adenocarcinoma between 1998 and 2011 were identified. A total of 469 patients remained after excluding patients with a history of pelvic radiation (n = 2), previous transanal endoscopic microsurgery or polypectomy of the primary lesion (n = 15), concurrent malignant tumor (n = 14), and no information about pre- or posttreatment T stage in the chart (n = 30). Preoperative CEA levels were available for 267 patients (57%).Preoperative chemoradiation therapy and total mesorectal excision were performed in patients with rectal cancer.The primary outcome measured was pathologic complete response.: Ninety-six patients (20%) were found to have a pathologic complete response in the operative specimen. Low pretreatment CEA (3.4 vs 9.6 ng/mL; p = 0.008) and smaller mean tumor size (4.2 vs 4.7 cm; p = 0.02) were significantly associated with pathologic complete response. Low CEA levels and interruption in chemoradiation therapy were significant predictors of pathologic complete response in the multivariate analysis. When stratifying for smoking status, low CEA level was significantly associated with pathologic complete response only in the group of nonsmokers (p = 0.02).This study was limited by its retrospective design, missing CEA values, and lack of tumor regression grade assessment.We demonstrated an association between low pretreatment CEA levels, interruption in chemoradiation therapy, and pathologic complete response in patients treated with neoadjuvant chemoradiation therapy for locally advanced rectal cancer. The predictive value of CEA in smokers can be limited, and further studies are needed to evaluate the impact of smoking on the predictive value of CEA levels for pathologic complete response in rectal cancer.

Limited data have been published regarding the long-term results of sacral nerve stimulation, or sacral neuromodulation, for severe fecal incontinence.The aim was to assess the outcome of sacral nerve stimulation with the use of precise tools and data collection, focusing on the long-term durability of the therapy. Five-year data were analyzed.Patients entered in a multicenter, prospective study for fecal incontinence were followed at 3, 6, and 12 months and annually after device implantation.Patients with chronic fecal incontinence in whom conservative treatments had failed or who were not candidates for more conservative treatments were selected.Patients with ≥ 50% improvement over baseline in fecal incontinence episodes per week during a 14-day test stimulation period received sacral nerve stimulation therapy.Patients were assessed with a 14-day bowel diary and Fecal Incontinence Quality of Life and Fecal Incontinence Severity Index questionnaires. Therapeutic success was defined as ≥ 50% improvement over baseline in fecal incontinence episodes per week. All adverse events were collected.A total of 120 patients (110 women; mean age, 60.5 years) underwent implantation. Seventy-six of these patients (63%) were followed a minimum of 5 years (maximum, longer than 8 years) and are the basis for this report. Fecal incontinence episodes per week decreased from a mean of 9.1 at baseline to 1.7 at 5 years, with 89% (n = 64/72) having ≥ 50% improvement (p0.0001) and 36% (n = 26/72) having complete continence. Fecal Incontinence Quality of Life scores also significantly improved for all 4 scales between baseline and 5 years (n = 70; p0.0001). Twenty-seven of the 76 (35.5%) patients required a device revision, replacement, or explant.The therapeutic effect and improved quality of life for fecal incontinence is maintained 5 years after sacral nerve stimulation implantation and beyond. Device revision, replacement, or explant rate was acceptable, but future efforts should be aimed at improvement.

Sacral nerve stimulation is effective in the treatment of urinary incontinence and is currently under Food and Drug Administration review in the United States for fecal incontinence. Previous reports have focused primarily on short-term results of sacral nerve stimulation for fecal incontinence. The present study reports the long-term effectiveness and safety of sacral nerve stimulation for fecal incontinence in a large prospective multicenter study.Patients with fecal incontinent episodes more than twice per week were offered participation in this multicentered prospective trial. Patients showing ≥ 50% improvement during test stimulation were offered chronic implantation of the InterStim Therapy system (Medtronic; Minneapolis, MN). The aims of the current report were to provide 3-year follow-up data on patients from that study who underwent sacral nerve stimulation and were monitored under the rigors of an Food and Drug Administration-approved investigational protocol.One hundred thirty-three patients underwent test stimulation with a 90% success rate, of whom 120 (110 females) with a mean age of 60.5 years and a mean duration of fecal incontinence of 7 years received chronic implantation. Mean length of follow-up was 3.1 (range, 0.2-6.1) years, with 83 patients completing all or part of the 3-year follow-up assessment. At 3 years follow-up, 86% of patients (P.0001) reported ≥ 50% reduction in the number of incontinent episodes per week compared with baseline and the number of incontinent episodes per week decreased from a mean of 9.4 at baseline to 1.7. Perfect continence was achieved in 40% of subjects. The therapy also improved the fecal incontinence severity index. Sacral nerve stimulation had a positive impact on the quality of life, as evidenced by significant improvements in all 4 scales of the Fecal Incontinence Quality of Life instrument at 12, 24, and 36 months of follow-up. The most common device- or therapy-related adverse events through the mean 36 months of follow-up included implant site pain (28%), paresthesia (15%), change in the sensation of stimulation (12%), and infection (10%). There were no reported unanticipated adverse device effects associated with sacral nerve stimulation therapy.Sacral nerve stimulation using InterStim Therapy is a safe and effective treatment for patients with fecal incontinence. These data support long-term safety and effectiveness to 36 months.

Magnetic sphincter augmentation, a successful treatment of gastroesophageal reflux disease, has been applied to treat fecal incontinence. The purpose of this feasibility study was to understand the safety profile as well as the potential benefit of this new device when it is implanted in patients with fecal incontinence.A magnetic anal sphincter device was surgically implanted in candidates with documented fecal incontinence of more than 2 episodes per week at 3 investigational centers in Europe and the United States following ethics/institutional review board approval. The magnetic anal sphincter device was placed around the anal canal via a single anterior incision. All data were collected prospectively. The primary outcome measure was the reduction of incontinent episodes based on a daily continence diary.To date 14 patients have been implanted with the device (all female; mean age, 62.8 y; range, 41-74 y) with a median follow-up of 6 months. There have been no intraoperative complications. Mean hospital stay was 3 days; range, 1 to 7 days. Adverse events were observed in 7 patients. Three patients are no longer implanted with a device; 2 devices were removed and one passed spontaneously following a separation at the suture connection. Five patients with 6-month follow-up demonstrated a mean reduction in the number of average weekly incontinence episodes from 7.2 to 0.7 (90.9%) and a mean reduction in Wexner Continence Score from 17.2 to 7.8 (54.7%). Compared with baseline, quality of life improved in all 4 domains of the fecal incontinence quality of life (FIQoL) scoring system. No patients have reported that their condition has worsened. Two patients at 1-year follow-up both reported perfect continence.This preliminary study describes the use of a new device to treat fecal incontinence. Compared with existing devices, implantation is simple and it requires no adjustments from the physician or patient once the device is implanted. Initial assessment with a small number of patients shows promising outcomes with a limited incidence of complications and good restoration of continence.

Transanal endoscopic microsurgery provides a minimally invasive alternative to radical surgery for excision of benign and malignant rectal tumors. The purpose of this study was to review our experience with transanal endoscopic microsurgery to clarify its role in the treatment of different types of rectal pathology.A prospective database documented all patients undergoing transanal endoscopic microsurgery from October 1996 through June 2008. We analyzed patient and operative factors, complications, and tumor recurrence. For recurrence analysis, we excluded patients with fewer than 6 months of follow-up, previous excisions, known metastases at initial presentation, and those who underwent immediate radical resection following transanal endoscopic microsurgery.Two hundred sixty-nine patients underwent transanal endoscopic microsurgery for benign (n = 158) and malignant (n = 111) tumors. Procedure-related complications (21%) included urinary retention (10.8%), fecal incontinence (4.1%), fever (3.8%), suture line dehiscence (1.5%), and bleeding (1.5%). Local recurrence rates for 121 benign and 83 malignant tumors were 5% for adenomas, 9.8% for T1 adenocarcinoma, 23.5% for T2 adenocarcinoma, 100% for T3 adenocarcinoma, and 0% for carcinoid tumors. All 6 (100%) recurrent adenomas were retreated with endoscopic techniques, and 8 of 17 (47%) recurrent adenocarcinomas underwent salvage procedures with curative intent.Transanal endoscopic microsurgery is a safe and effective method for excision of benign and malignant rectal tumors. Transanal endoscopic microsurgery can be offered for (1) curative resection of benign tumors, carcinoid tumors, and select T1 adenocarcinomas, (2) histopathologic staging in indeterminate cases, and (3) palliative resection in patients medically unfit or unwilling to undergo radical resection.

PURPOSE: In this study we compared the outcomes of patients with complex cryptoglandular fistulas treated by endorectal advancement flap or anal fistula plug. METHODS: We performed a retrospective analysis of patients with transsphincteric anal fistulas treated by endorectal advancement flap or anal fistula plug from January 1996 through April 2007. Patients with noncryptoglandular fistulas or insufficient follow-up were excluded. Results were obtained with a combination of chart reviews, mailed questionnaire, and phone interviews. Success was defined as a closed external opening in absence of symptoms at a minimal follow-up time of six months. RESULTS: Forty-three patients had an endorectal advancement flap and 37 patients had an anal fistula plug procedure. The two cohorts were comparable for age, gender, smoking status, fistula type, and previous failed treatments. The success rate was 63 percent in the endorectal advancement flap group and 32 percent in the anal fistula plug group (P = 0.008), after a mean follow-up of 56 (range, 6-136) months for endorectal advancement flap and 14 (range, 6-22) months for anal fistula plug. CONCLUSIONS: The current study indicates that the endorectal advancement flap provides a higher success rate than the anal fistula plug. Randomized trials are needed to further elucidate the efficacy and potential functional benefit of the anal fistula plug in the treatment of complex anal fistulas.

Objective The Fecal Incontinence Severity Index (FISI) is widely used in the assessment of patients with faecal incontinence, but the relationship between FISI and the measurements of quality of life, such as the Fecal Incontinence Quality of Life Scale (FIQL) and the Medical Outcomes Survey (SF-36) has not been evaluated previously. The aim of the present study was to evaluate the relationship between disease severity and quality of life in a large cohort of patients. Method Five hundred and two consecutive patients (84.4% female, mean age 56 years) were evaluated for faecal incontinence between May 2004 and October 2005. Patients completed FISI, FIQL and SF-36 questionnaires. Pearson's coefficients were determined for the relationships between FISI and subscales of FIQL and SF-36. Quality of life scores were compared between groups of patients with different levels of incontinence severity (mild, moderate, severe) using Student's t-test. Results Sixty-eight per cent of patients were incontinent of solid stool, 62% of liquid stool, and 90% of gas or mucus. The average FISI score was 36 (0–61). Moderate correlations were found between FISI and all subscales in FIQL (negative 0.29 to 0.41; P
