Background: Pelvic organ prolapse is reported in 30% of women presenting with rectal prolapse. Combined repair is a viable option to avoid the need for future pelvic floor interventions. However, the added impact of adding a modicum of middle compartment suspension by closing the pouch of Douglas during a rectal prolapse repair has not been studied., Objective: The study aimed to assess the impact of middle compartment suspension on the durability of rectal prolapse repair. We also aimed to determine whether adding some form of pouch of Douglas closure to achieve middle compartment suspension leads to any improvements in the rates or severity of postoperative constipation or in the rates or severity of postoperative fecal incontinence., Design: This study was a retrospective analysis of a multicenter prospective database., Setting: Data were analyzed from the Pelvic Floor Disorders Consortium Quality Improvement in Rectal Prolapse Surgery database. Deidentified surgeons at more than 20 sites (75% academic, 81% high volume) self-reported patient demographics, previous repairs, symptoms of fecal incontinence and obstructed defecation, and operative details, including addition of concomitant gynecologic repairs, use of mesh, posterior or ventral dissection, and sigmoidectomy., Patients: Patients were included who underwent abdominal repair for rectal prolapse., Interventions: Abdominal rectopexy procedures with and without middle compartment suspension were compared. Middle compartment suspension was defined as excision and closure of the pouch of Douglas with some degree of colpopexy or culdoplasty., Main Outcome Measures: The primary outcome of prolapse recurrence and secondary outcomes of incontinence and constipation were calculated via univariate and multivariable regression by comparing those who underwent rectopexy with and without middle compartment suspension., Results: Of the 198 patients (98% female, age 60.2 ± 15.6 years) who underwent abdominal repairs (59% robotic), 138 patients (70%) underwent some concomitant middle compartment suspension. Patients who had an added middle compartment suspension seemed to have lower early rectal prolapse recurrences. On multivariable regression to control for age, previous repairs, and the use of mesh, addition of some form of pouch of Douglas repair was associated with a decrease in short-term recurrences., Limitations: Our data need to be interpreted cautiously. Future studies are critically needed to further explore this observation, with an a priori, prospective definition of middle compartment suspension, validated measurement of concomitant pathology, and longer follow-up., Conclusion: Our results suggest that some middle compartment suspension at the time of rectal prolapse repair may improve short-term durability of rectal prolapse repair.

Sin embargo, no se ha estudiado el impacto adicional de agregar un mínimo de suspensión del compartimento medio cerrando el fonde de saco de Douglas durante una reparación de prolapso rectal.OBJETIVO:Nuestro objetivo fue evaluar el impacto de la suspensión del compartimento medio con respecto a la durabilidad de la reparación del prolapso rectal. Quisimos de igual manera determinar si el agregado de algún tipo de cierre del fondo de saco de Douglas para lograr la suspensión del compartimento medio conduce a alguna mejora en las tasas o la gravedad del estreñimiento posoperatorio así como en las tasas o la gravedad de la incontinencia fecal posoperatoria.DISEÑO:Análisis retrospectivo de una base de datos prospectiva.ESCENARIO:Base de datos Multicenter Pelvic Floor Disorders Consortium Prospective Quality Improvement. Cirujanos no identificados en >20 sitios (75% académicos, 81% de alto volumen) datos demográficos de pacientes auto informados, reparaciones previas, síntomas de incontinencia fecal y defecación obstruida, y detalles quirúrgicos, incluida la suma de reparaciones ginecológicas concomitantes, uso de malla, disección anterior o posterior y sigmoidectomía.INTERVENCIONES:Se compararon los procedimientos de rectopexia abdominal con y sin suspensión del compartimento medio). La suspensión del compartimento medio se definió como la escisión y cierre del fondo de saco de Douglas con algún grado de colpopexia o culdoplastia.RESULTADOS:El resultado principal de la recurrencia del prolapso y los resultados secundarios de incontinencia y estreñimiento se calcularon mediante regresión uni y multivariable al comparar los que fueron sometidos a rectopexia con y sin suspensión del compartimento medio.PACIENTES:Pacientes sometidos a reparación abdominal por prolapso rectal.RESULTADOS:De los 198 pacientes (98% mujeres, edad 60,2 ± 15,6 años) sometidas a reparaciones abdominales (59% robótica), 138 (70%) fueron sometidas igualmente y de manera concomitante a alguna suspensión del compartimento medio. Los pacientes a los que se les añadió una suspensión del compartimento medio parecían tener menores recurrencias tempranas del prolapso rectal y, en la regresión multivariable para controlar la edad, las reparaciones previas y el uso de malla, la adición de alguna forma de reparación del fondo de saco de Douglas se asoció con una disminución de las recurrencias a corto plazo.LIMITACIONES:Nuestros datos deben interpretarse con cautela. Se necesitan de manera critica, estudios futuros para explorar más a fondo esta observación, con una definición prospectiva a priori de la suspensión del compartimento medio, una medición validada de la patología concomitante y un seguimiento más prolongado.CONCLUSIONES:Nuestros resultados sugieren que alguna suspensión del compartimento medio en el momento de la reparación del prolapso rectal puede mejorar la durabilidad a corto plazo de la reparación del prolapso rectal.

Background: Nonspecific acute pouchitis is common in patients with ulcerative colitis who undergo IPAA, but there is disagreement about the rate at which this occurs in patients with familial adenomatous polyposis., Objective: This study aimed to define the rate at which nonspecific acute pouchitis occurs in patients with familial adenomatous polyposis., Setting: This study was conducted at a hereditary colorectal cancer center in a large academic medical center., Design: This is a retrospective cohort study using prospectively gathered data., Patients: Patients with familial adenomatous polyposis who have had IPAA were included., Interventions: Symptoms, pouchoscopy and pouch radiography, and pouch biopsy were evaluated., Main Outcome Measures: The primary outcomes measured were the presence of nonspecific acute pouchitis and the alternative diagnosis of pouch dysfunction., Results: There were 250 patients with familial adenomatous polyposis who had undergone IPAA; 38 (15.2%) had been labeled as having "pouchitis": 23 men and 15 women. Median age was 55 years (range, 18-90 years). No patient had nonspecific, acute pouchitis as defined by our criteria. In 9 cases, the diagnosis was derived from benign ulcers common in ileal pouches. Stool frequency was the most common symptom associated with the "pouchitis" label, but actual causes for the frequency included poor pouch emptying, poor eating habits, poor bowel habits, and afferent limb syndrome. Median stool frequency was 9, ranging from 4 to 15 per day. Every patient had at least 1 pouch endoscopy, and the median number was 19 per patient (range, 1-21). Nine patients had pouch biopsies to rule out inflammation; all showed chronic active enteritis, a normal finding in ileal pouches., Limitations: This study was limited by its retrospective nature., Conclusions: We could not confirm any case of nonspecific acute pouchitis in patients with familial adenomatous polyposis. Those caring for patients with familial adenomatous polyposis who have a pouch should seek causes for pouch-related symptoms other than "pouchitis."

La mediana de edad fue de 55 años (rango de 18 a 90 años). Ningún paciente tuvo pouchitis aguda inespecífica según lo definido por nuestros criterios. En 9 casos el diagnóstico se derivó de úlceras benignas frecuentes en bolsas ileales. La frecuencia de las evacuaciones fue el síntoma más común asociado con la etiqueta "pouchitis", pero las causas reales de la frecuencia, incluyeron un mal vaciado de la bolsa, malos hábitos alimenticios, malos hábitos intestinales y síndrome de asa aferente. La frecuencia media de las evacuaciones fue de 9, con un rango de 4 a 15 por día. A cada paciente se le realizó al menos una endoscopia de la bolsa: la mediana fue de 19 por paciente (rango de 1 a 21). A 9 pacientes se les realizó biopsia de bolsa para descartar inflamación: todos mostraron enteritis activa crónica, un hallazgo normal en las bolsas ileales.LIMITACIONES:Naturaleza retrospectiva del estudio.CONCLUSIONES:No pudimos confirmar ningún caso de pouchitis aguda e inespecífica en pacientes con PAF. Aquellos que atienden a pacientes con PAF con bolsa ileal, deben buscar otras causas para los síntomas relacionados con la bolsa que no sean "pouchitis".

Background: Bacteria that produce collagen-digesting enzymes (collagenolytic bacteria) have been shown to play a critical and previously unappreciated role in anastomotic leak pathogenesis by breaking down host tissue extracellular matrix proteins. Detection of these bacteria is labor intensive, and no screening method currently exists., Objectives: We evaluated a rapid screening method developed to detect the presence of these collagenolytic bacteria in clinical samples, such as drain fluid, anastomotic tissue, or feces., Design: We compared a new method of detecting collagenolytic bacterial species with a previously used technique using samples from a murine experimental model and then demonstrated the utility of this screening method in samples from patients with anastomotic complications., Settings: All of the laboratory work and previous murine experiments were performed in Dr Alverdy's laboratory at the University of Chicago under institutional review board-approved protocols., Patients: Samples from patients with challenging wound complications were provided by participating clinicians with verbal patient consent. Given the small number of patients, this was determined to be institutional review board exempt., Main Outcome Measures: Whether this analysis can influence patient management and outcomes will require additional study., Results: This screening method detects numerous strains of bacteria with collagenolytic properties, including the collagenolytic species that have been implicated previously in anastomotic leak. Once collagenolytic strains are identified, they can be speciated and tested for antibiotic resistance using standard laboratory techniques., Limitations: This study is limited by the small number of patient samples tested., Conclusions: We demonstrated the potential applicability of this assay to evaluate rare and complex anastomotic complications that often require analysis beyond standard culture and sensitivity assays. Future applications of this method may allow the development of strategies to prevent anastomotic leak related to collagenolytic bacteria. See Video Abstract at http://links.lww.com/DCR/A962.

Background: There are various surgical techniques used treat anal fistulas. The adoption and success rates of newer techniques have not been clearly established., Objective: The purpose of this study was to determine the healing rate after operations for anal fistulas in New England colorectal surgery practices., Design: We conducted a retrospective review of a prospectively collected database., Settings: The study was conducted at colorectal surgery practices in New England., Patients: A prospective, multicenter registry was created by the New England Society of Colon and Rectal Surgeons. Surgeons were invited to collect data prospectively regarding patients operated on for anal fistulas between January 1, 2011, and August 1, 2013. Fistula classification, surgical intervention, continence scores, and healing were determined by the treating surgeon., Intervention: Operation for anal fistula was performed., Main Outcome Measures: We measured the proportion of patients with healed fistulas at 3 months., Results: Sixteen surgeons submitted data regarding 240 operations for fistula with curative intent. Mean patient age was 45 ± 14 years. A total of 158 patients (66%) were men, and 110 (46%) had undergone an anorectal operation. Twenty-nine (12%) had Crohn's disease. The healing rates of fistulotomy, advancement flap, and fistula plugs at 3 months were 94% (95% CI, 89-97), 60% (95% CI, 33-77), and 20% (95% CI, 5-50). The healing rate of the ligation of intersphincteric fistula tract procedure at 3 months was 79% (95% CI, 65-88). Hospital site was the only variable associated with healing (p < 0.05). Hospitals that performed more ligation of intersphincteric fistula tract procedures had higher healing rates at 3 months (p < 0.0001)., Limitations: This study was limited by selection bias and reporting bias., Conclusions: A wide variety of techniques are used to treat anal fistulas in our region. Fistulotomy continues to have excellent results. There has been enthusiastic early adoption of the ligation of intersphincteric fistula tract technique. Early healing rates after the ligation of intersphincteric fistula tract procedure appear to be excellent.

Background: A large proportion of patients with a colostomy or an ileostomy develop parastomal hernias. The placement of a reinforcing material at the stoma site may reduce parastomal hernia incidence., Objective: We aimed to assess the safety and efficacy of stoma reinforcement with sublay placement of non-cross-linked porcine-derived acellular dermal matrix at the time of stoma construction., Design: This is a randomized, patient- and third-party assessor-blind, controlled trial., Settings: This study took place in colorectal/general surgery institutions., Interventions: Patients were prospectively randomly assigned to undergo standard end-stoma construction with or without porcine-derived acellular dermal matrix reinforcement., Patients: Patients undergoing construction of a permanent stoma were eligible. A total of 113 patients (59 men, 54 women; mean age, 60 years; mean BMI, 25.4 kg/m) participated: 58 controls and 55 with reinforcement., Main Outcomes Measures: The incidence of parastomal hernia, safety, and stoma-related quality of life were assessed., Results: Intraoperative complications and blood loss were similar between groups. Quality-of-life scores were similar through 24 months of follow-up. At 24 months of follow-up, the incidence of parastomal hernias was similar for both groups (12.2% of the porcine-derived acellular dermal matrix group and 13.2% of controls)., Limitations: Study limitations include the inclusion of ileostomy and colostomy patients, open and laparoscopic techniques, and small numbers of patients at follow-up., Conclusions: Safety and quality-of-life data from this randomized control trial show similar outcomes in both groups. Prosthetic reinforcement of stomas was safe, but it did not significantly reduce the incidence of parastomal hernia formation., Clinical Trial Registration: Identification no. NCT00771407.

Background: Stage-specific survival for colon cancer improves when more lymph nodes are reported in the surgical specimen. This has led to a minimum standard of identifying 12 lymph nodes as a quality indicator., Objective: The aim of this study was to determine whether the addition of Schwartz solution increases node yield and impacts pathologic staging., Design: This is a prospective cohort study., Setting: The study was conducted in an academic medical center., Patients: Included were 104 consecutive patients with colorectal cancer., Main Outcome Measures: Lymph node counts before and after specimen treatment with Schwartz solution and incidence of upstaging were measured., Results: An additional 20 minutes (interquartile range, 15-40 minutes) was spent searching for lymph nodes, increasing the median number of nodes from 22.5 to 29.0 nodes. However, only 1 patient was upstaged. Schwartz solution decreased the number of specimens with less than 12 lymph nodes from 15 to 6. The following factors were associated with Schwartz solution leading to the detection of additional nodes: number of nodes detected initially with formalin only (p < 0.000), mesenteric fat volume (p < 0.000), mesenteric fat weight (p < 0.000), length of specimen (p < 0.016), tumor greatest dimension (p < 0.016), patient body surface area (p < 0.034), and patient age (p < 0.003)., Limitations: Clinical data for this study were obtained retrospectively and were not available for all of the patients., Conclusions: Although Schwartz solution increased the number of nodes detected in 95% of patients and improved compliance with the 12-node standard for colon resection, there was minimal impact on cancer staging. Upstaging is unlikely to explain the increase in overall survival in patients with higher lymph node counts, casting doubt on the validity of this process measure as a meaningful quality indicator. Rather, the lymph node count may be a reflection of inherent tumor biology or host-related factors.

Background: Surgical site infections are a major source of expense and morbidity after colon resection., Objective: This study aimed to assess the effect of a targeted intervention to improve compliance with Surgical Care Improvement Project measures on the incidence of surgical site infection., Study Design: A cohort of patients was prospectively monitored., Setting: The investigation was conducted at a university teaching hospital., Patients: Consecutive patients underwent open colon resection with anastomosis., Intervention: A multidisciplinary committee consisting of a surgeon, anesthesiologist, nurses, and quality specialists was convened in late 2004 and a series of initiatives were designed, implemented, and tracked to improve performance on the 4 infection-related components of the Surgical Care Improvement Project program., Main Outcome Measures: Compliance with the 4 Surgical Care Improvement Project process measures and the rate of surgical site infection were documented., Results: There was no improvement in the use of appropriate antibiotics (P = .66), administration within 1 hour of incision (P = .11), cessation within 24 hours (P = .36), or achievement of normothermia (P = .46). Similarly, there was no effect whatsoever on the incidence of surgical site infection over the study period (P = .84)., Limitations: The single-institution nature of the study limited its usefulness., Conclusions: A 5-year multidisciplinary program of targeted initiatives and interventions failed to improve compliance with Surgical Care Improvement Project measures or to decrease surgical site infection at our institution where colon resections are performed almost exclusively by high-volume specialists. These efforts consumed considerable resources and expenditures, but were of little or no value in our setting.

Purpose: This study aimed to determine the outcomes and healing rate after fistula surgery across a broad spectrum of colorectal practices., Methods: A prospective, multicenter outcomes registry was created by the New England Regional Chapter of The American Society of Colon and Rectal Surgeons. All consecutive patients undergoing surgical treatment of an anal fistula by a participating surgeon from October 1, 2007 to September 30, 2008, were entered. Demographics, fistula characteristics including Parks' classification, smoking history, previous vaginal deliveries, diagnosis of Crohn's disease, Fecal Incontinence Severity Index, and operations performed were noted. A follow-up datasheet recorded postoperative complications, healing at one and three months, and postoperative continence scores. Factors associated with healing and treatment success were compared by use of Fisher's exact test., Results: Twenty-five surgeons at 13 hospitals entered 245 patients (162 male, 83 female) in the registry. Seventy-five patients had recurrent fistulas, 51 had multiple tracts, 62 were smokers, and 24 had Crohn's disease. The overall healing rate was 19.5% at one month and 63.2% at three months. Female gender (P = 0.04) and recurrent fistula (P = 0.03) were associated with nonhealing, and 28.4% of patients required additional surgery. The best healing rate was associated with fistulotomy (87%), whereas a plug had the worst healing rate (32%, P = 0.001)., Conclusions: Surgical treatment of an anal fistula is associated with a substantial risk of nonhealing at three months. Fistulotomy had a high success rate, whereas the bioprosthetic plug had the lowest success rate. Multicenter studies comparing treatment options for similar fistulas are needed.

Purpose: This study was designed to determine the impact of a history of sexual abuse on the outcomes of ileorectal anastomosis for slow-transit constipation., Methods: All patients undergoing subtotal colectomy and ileorectal anastomosis for slow-transit constipation by a single surgeon at a university hospital from 1991 to 2006 were identified. Age, time since surgery, psychiatric diagnoses, number of previous operations, and "functional" disorders were collected. Patients were questioned about a history of anal and vaginal sexual abuse. Use of alternative healthcare practitioners and remote postoperative physician visits for abdominal symptoms were elicited., Results: Fifteen patients met study criteria, and 13 came for assessment. All were women, all were highly satisfied with the results of their surgery, and all said they would request the procedure again. Median age was 38 (range, 29-58) years, and time to follow-up was 97 (range, 25-166) months. Eleven subjects (85%) reported a current psychiatric condition being treated with psychotropic medication. Eight (62%) reported a history of sexual abuse, and seven (88%) reported both anal and vaginal abuse. Patients with a history of sexual abuse had a total of 32 operations before colectomy and 30 functional diagnoses, compared with a total of 3 operations and 3 functional diagnoses in the nonabused group (P = 0.001 and P = 0.0002, respectively). Similarly, seven of eight abused patients (88%) sought additional medical care for abdominal complaints after this surgery, compared with none of five in the nonabused group (P = 0.005)., Conclusion: A history of sexual abuse should be sought in patients with slow-transit constipation, because it is a strong predictor of more functional diagnoses, more precolectomy operations, and more postcolectomy medical care for abdominal complaints.

Purpose: This study was designed to determine the prevalence and risk factors for anal squamous intraepithelial lesions and human papillomavirus infection in a rural population of HIV-infected males., Methods: A cross-sectional study was performed. Risk factors were collected. Anal Papanicolaou smear and human papillomavirus screening for oncogenic types were performed., Results: Of 211 eligible male patients, 149 (70.6 percent) participated. HIV transmission risk was predominantly males who have sex with males (82 percent). The mean duration of HIV infection was 9.9 years. Ninety (60 percent) males had abnormal anal cytology, including atypical cells of unknown significance 40 (26 percent), low-grade squamous intraepithelial lesions 28 (19 percent), and high-grade squamous intraepithelial lesions 22 (15 percent). Human papillomavirus was detected in 61 percent. Binary logistic regression adjusted risks for abnormal anal cytology included: males who have sex with males (P<0.001), human papillomavirus infection (P<0.001), history of anogenital warts (P=0.014), and the mean lowest CD4 count (abnormal cytology, 158 (standard deviation, 135), negative cytology, 208 (standard deviation, 180; P=0.017)). Twenty-two patients with high-grade squamous intraepithelial lesions underwent colorectal surgical examination and anoscopy. Two (10 percent) were found to have invasive squamous-cell carcinoma and three (15 percent) others had mass lesions with high-grade squamous intraepithelial lesions., Conclusions: Anal squamous intraepithelial lesions and oncogenic human papillomavirus are highly prevalent in males infected with HIV and living in a rural setting.

Serotonin (5-HT) is most commonly thought of as a neurotransmitter in the central nervous system. However, the predominant site of serotonin synthesis, storage, and release is the enterochromaffin cells of the intestinal mucosa. Within the intestinal mucosa, serotonin released from EC cells activates neural reflexes associated with intestinal secretion, motility, and sensation. Two important receptors for serotonin that are located in the neural circuitry of the intestines are the 5-HT(3) and 5-HT(4) receptors; these are the targets of drugs designed to treat gastrointestinal disorders. 5-HT(3) receptor antagonists are used to treat nausea and emesis associated with chemotherapy and for functional disorders associated with diarrhea. 5-HT(4) receptor agonists are used as promotility agents to promote gastric emptying and to alleviate constipation. Because of the importance of serotonin in normal gut function and sensation, a number of studies have investigated potential changes in mucosal serotonin signaling in pathologic conditions. Despite the inconsistencies in the current literature, changes in serotonin signaling have now been demonstrated in inflammatory bowel disease, irritable bowel syndrome, postinfectious irritable bowel syndrome, and idiopathic constipation. Emerging evidence has led to many contradictory theories regarding serotonin signaling and its roles in the pathology of gut disorders. This review summarizes the current medications affecting serotonin signaling and provides an overview of our current knowledge of the changes in serotonin that occur in pathologic conditions.

Purpose: Diverticulitis has been described as a more virulent disease in young patients, necessitating an aggressive surgical approach. We hypothesized that the subgroup of young patients who do not require surgery on their initial presentation are unlikely to present at a later date with perforation and do not always require prophylactic resection as commonly recommended., Methods: A retrospective chart review was conducted of all patients presenting to Fletcher Allen Health Care, the teaching hospital of the University of Vermont, from January 1, 1990 to June 30, 2001. Outcomes in patients aged 50 years or younger (Group 1) were compared with patients older than aged 50 years (Group 2) using a log-rank test., Results: A total of 762 patients were admitted with sigmoid diverticulitis during the study period, 238 (31 percent) of whom underwent surgery. Two hundred fifty-nine patients (34 percent) were younger than aged 50 years (Group 1). The risk of requiring surgery on initial hospital presentation was similar between the two groups (24 vs. 22 percent, respectively; P = 0.8). However, Group 1 patients were more likely to be treated operatively at some point during the study period (40 vs. 26 percent; P = 0.001) because of an increase in elective resections. Of 196 patients in Group 1 who had an initial medically managed admission, only 1 presented at a later date with perforation (0.5 percent)., Conclusions: The risk of subsequent diverticular perforation in medically managed young patients with sigmoid diverticulitis is very low. As such, the frequently espoused policy of routine surgery after a single attack of diverticulitis in young patients may not be warranted. A more selective approach seems to be safe.

Purpose: Lateral internal sphincterotomy is an effective treatment for chronic anal fissures; however, the risk of "incontinence" has generated interest in pharmacologic approaches that are far less effective and may be poorly tolerated. This study was designed to objectively define the risk of incontinence with sphincterotomy using the Fecal Incontinence Severity Index and assess the implications for quality of life using the Fecal Incontinence Quality of Life Scale., Methods: A prospective study was undertaken on all patients undergoing lateral internal sphincterotomy for a chronic anal fissure by a single surgeon at a university teaching hospital from January 1, 2000 to September 30, 2002. All patients had failed at least six weeks of nonoperative management. Patient demographics and use of nitroglycerin were noted. The Fecal Incontinence Severity Index was measured preoperatively and at a six-week postoperative visit when fissure healing and postoperative complications were assessed. The Fecal Incontinence Quality of Life Scale was administered to patients with an incontinence score>0., Results: Thirty-five patients (15 males) underwent sphincterotomy during the study period. Thirty-one of 35 had failed nitrates: 10 because of unacceptable side effects, and 21 because of lack of efficacy. Thirty-two patients returned for their six-week postoperative visits, and two completed their questionnaires by telephone. One patient was lost to follow-up. Mean age was 41.2 (range, 21-67) years. Thirty of 32 (94 percent) evaluable fissures had healed by six weeks, one healed by three months, and the other required V-Y anoplasty. There were two minor complications. Three patients had postoperative deterioration in their continence score. Quality of life deteriorated in only one patient., Conclusions: Lateral internal sphincterotomy is a safe and effective treatment for chronic anal fissures that only occasionally impairs continence and rarely diminishes quality of life.

Purpose: This study was conducted to compare continence after double-stapled ileal pouch-anal anastomosis and laparoscopic cholecystectomy using the Fecal Incontinence Severity Index and to assess the impact on quality of life using the Fecal Incontinence Quality of Life Scale., Methods: Fifty-five patients randomly selected from a prospective pelvic pouch database were matched with regard to age and gender with patients who had undergone laparoscopic cholecystectomy during the same time interval by the same surgeon. Patients were mailed the two questionnaires, which were reviewed by an independent observer. Demographics, duration since surgery, and functional results were recorded. The Fecal Incontinence Severity Index and Fecal Incontinence Quality of Life scores were compared by the analysis of variance method., Results: Fifty-one pelvic pouch and 50 laparoscopic cholecystectomy patients were able to be contacted and completed both of the measuring tools. For the pouch patients, the median number of bowel movements per day was six (range, 2-15), with two patients reporting more than occasional nighttime incontinence. Mean incontinence scores were higher for the pelvic pouch patients than for the laparoscopic cholecystectomy patients (17.8 vs. 10.7; P = 0.03). However, the quality-of-life scores were very similar: lifestyle (3.8 vs. 3.83; P = 0.88), depression/self-perception (3.81 vs. 3.83; P = 0.94), embarrassment (3.76 vs. 3.8; P = 0.84), and behavior/coping (3.57 vs. 3.71; P = 0.5)., Conclusion: Although continence is clearly altered after pelvic pouch surgery, quality of life is extremely well preserved.

Damaged mucosal sites seem to be vulnerable to tumor cell implantation. We describe a case of exfoliated tumor cells from a sigmoid colon cancer seeding a long-standing anal fistula. The implications of this finding are reviewed.

Purpose: The purpose of this study was to use the Fecal Incontinence Severity Index to assess fecal incontinence after fistulotomy and to correlate the Fecal Incontinence Severity Index score with quality-of-life measures., Methods: A retrospective chart review was performed on consecutive patients undergoing fistulotomy by a single colon and rectal surgeon at a university hospital from 1991 to 1999. Demographics, fistula anatomy, surgical technique, and length of follow-up were recorded. Mailed questionnaires and telephone interviews were conducted to determine the Fecal Incontinence Severity Index score, pad usage, lifestyle restriction, and psychosocial factors. A linear regression model was used to determine the relationship of clinical factors with Fecal Incontinence Severity Index. One-way ANOVA was used to correlate Fecal Incontinence Severity Index with quality-of-life measures., Results: Of 110 patients who underwent fistulotomy, 96 (88 percent) had complete follow-up. Mean age was 48 (range, 17-84) years, and 68 percent were male. Follow-up was less than two years in 26 percent, two to five years in 39 percent, and more than five years in 35 percent. Of these patients, 41 percent had intersphincteric fistulas, whereas 59 percent had transsphincteric fistulas. Median Fecal Incontinence Severity Index score was 6, with a mean of 13 (maximum Fecal Incontinence Severity Index = 61); 36 percent had a Fecal Incontinence Severity Index score of zero. Linear regression revealed that only the amount of external sphincter divided correlated with Fecal Incontinence Severity Index score (P = 0.05). Quality-of-life measures strongly correlated with Fecal Incontinence Severity Index by analysis of variance (P < 0.01 for pad usage, lifestyle restriction, depression, and embarrassment), with substantial quality-of-life drop-off documented with Fecal Incontinence Severity Index >30., Conclusion: The Fecal Incontinence Severity Index is an excellent tool to gauge quality of life after fistulotomy. Fecal Incontinence Severity Index scores >30 predict a detrimental effect on quality of life.

A 40-year-old man with ganglioneuromatous polyposis and an aggressive coexisting colorectal cancer is described. Contrary to previous reports, we believe that ganglioneuromatous polyposis should be considered a premalignant condition.

Background: Ogilvie's syndrome, or acute colonic pseudo-obstruction, is a common and relatively dangerous condition. If left untreated, it may cause ischemic necrosis and colonic perforation, with a mortality rate as high as 50 percent. Neostigmine enhances excitatory parasympathetic activity by competing with acetylcholine for attachment to acetylcholinesterase at sites of cholinergic transmission and enhancing cholinergic action. We hypothesized that neostigmine would restore peristalsis in patients with acute colonic pseudo-obstruction., Methods: Twenty-eight patients at Fletcher Allen Health Care and The Cleveland Clinic Foundation were treated for acute colonic pseudo-obstruction with neostigmine 2.5 mg IV over 3 minutes while being monitored with telemetry. Mechanical obstruction had been excluded., Results: Complete clinical resolution of large bowel distention occurred in 26 of the 28 patients. Time to pass flatus varied from 30 seconds to 10 minutes after administration of neostigmine. No adverse effects or complications were noted. Of the two patients who did not resolve, one had a sigmoid cancer that required resection and one patient died from multiorgan failure., Conclusion: This study supports the theory that acute colonic pseudo-obstruction is the result of excessive parasympathetic suppression rather than sympathetic overactivity. We have shown that neostigmine is a safe and effective treatment for acute colonic pseudo-obstruction.

Purpose: Topical nitrates have been shown to cause nitric oxide-mediated relaxation of the internal anal sphincter. Previous reports have suggested initial efficacy in the treatment of anal fissures. The aim of this study was to assess the longer-term usefulness of this treatment., Methods: Thirty-three patients with an anal fissure were treated with topical 0.3% nitroglycerin ointment, applied to the anoderm three times per day and after bowel movements. Patients were followed up by office visits and telephone calls until symptoms were completely resolved or treatment was noted to be ineffective or intolerable., Results: Thirty-three patients were treated, 16 with acute fissures, and 17 with chronic fissures. Nitroglycerin was effective in 9 of 16 acute fissures (56%), and 7 of 17 chronic fissures (41%). Even when effective, 75% of patients reported an adverse reaction., Conclusions: Topical nitroglycerin was only effective in approximately one-half of patients with an anal fissure. There was a very high incidence of adverse reactions. In our experience nitroglycerin more often causes a headache than treats the symptoms of anal fissure.

Purpose: Most general surgery residents obtain scant exposure to anorectal disease during training. The aim of this study was to determine whether adding a colon and rectal surgeon to the faculty of a general surgery training program improves the amount or quality of the anorectal surgical experience., Methods: The surgical experience of all graduating residents from our university teaching program was reviewed during a ten-year period. Complete case data were obtained from the Residency Review Committee for surgery. The total small-intestine, colon and anorectal caseload was analyzed during the five-year period preceding the arrival of the colon and rectal surgeon and compared with the subsequent five-year period after the surgeon's arrival., Results: There was a substantial increase in small-intestine (470 vs. 306) and anorectal cases (462 vs. 338). There was a particularly dramatic increase in anorectal cases performed during the chief resident year (159 vs. 36), which held true for all categories of anorectal cases., Conclusions: The addition of a full-time colon and rectal surgeon to a university general surgery residency program was associated with an increase in small-intestine and especially anorectal cases. However, most striking was the greater than fourfold increase in the number of anorectal cases performed during the chief resident year. This seems to reflect an increase in complexity of anorectal cases and an increased interest in anorectal surgery among general surgery residents.

Purpose: Ileal pouch-anal anastomosis is widely claimed to have replaced total proctocolectomy with ileostomy as the "procedure of choice" for ulcerative colitis, largely on the basis of a perceived improved quality of life. There exists relatively little support for this assertion in the literature. Our aim was to determine if educated patients choosing total proctocolectomy with ileostomy have a similar quality of life as with ileal pouch-anal anastomosis., Methods: All patients with ulcerative colitis referred to a single surgeon and deemed an appropriate surgical candidate were educated and then offered ileal pouch-anal anastomosis or total proctocolectomy with ileostomy. Age, gender, and complications (including pouchitis) were recorded prospectively, and all patients were questioned regarding functional outcome and level of satisfaction. They were then asked to complete a slightly modified Inflammatory Bowel Disease Questionnaire, which was analyzed by categoric and overall scores., Results: Sixty-seven patients underwent elective surgery for ulcerative colitis during the study period. Fifty-five patients chose ileal pouch-anal anastomosis, and 12 had total proctocolectomy with ileostomy. The groups were similar except for younger age and longer follow-up in the ileal pouch-anal anastomosis group. Patients undergoing ileal pouch-anal anastomosis had significantly more short-term or long-term complications (49 vs. 8 percent), with pouchitis being the most frequent complication. There was no difference in level of satisfaction between the two groups, and no patient in either group wishes they had undergone the other procedure. There was no difference in the overall or any categoric Inflammatory Bowel Disease Questionnaire score., Conclusion: Patient satisfaction with both procedures was similarly high. Patients who undergo ileal pouch-anal anastomosis can expect a high level of satisfaction, with a good quality of life. However, educated patients choosing an ileostomy can achieve the same quality of life, without the higher complication rate associated with a pelvic pouch.

The management of anorectal disease remains a major component in the practice of the general surgeon. To assess the adequacy of general surgery residencies in addressing this educational need, data were obtained from the Residency Review Committee (RRC) for surgery on the anorectal experience of all graduating residents in accredited United States programs for a recent five-year period (1987-1991). The mean number of anorectal procedures in which a resident participated throughout the residency was 30.0. This is then further subdivided by type of procedure. It is concluded that general surgery residency programs tend to provide an inadequate training experience in anorectal surgery.

Temporary diverting loop ileostomy is a generally accepted component of the ileal pouch-anal anastomosis (IPAA) procedure. Ileostomy closure is usually performed within two to three months but may be delayed because of disruption of the ileonanal anastomosis, suspected leak from the ileal reservoir, concomitant medical problems, or patient convenience. Of 362 patients undergoing IPAA at The Cleveland Clinic Foundation for inflammatory bowel disease, 10 have had their ileostomy closures delayed for more than six months. Clinical and manometric parameters are examined in these patients and compared with those who had earlier closure. There appears to be no significant difference in the functional outcome of IPAA in these patients in terms of number of bowel movements and degree of continence. Reservoir compliance and maximum tolerated volumes are similar. We conclude that delaying ileostomy closure for more than six months after IPAA has no deleterious effect on pouch function.

Patients with Crohn's colitis are generally not considered candidates for the ileal pouch-anal anastomosis (IPAA) procedure. We reviewed 362 consecutive patients undergoing IPAA and analyzed the outcome of this procedure on 25 patients with a preoperative diagnosis of mucosal ulcerative colitis who were subsequently proven to have Crohn's disease. The mean follow-up was 38.1 months. Sixteen patients have a functioning pouch, seven have required pouch excision, one is diverted, and one has died. Only one of nine patients in whom there was a preoperative clinical feature suggestive of Crohn's disease has a functioning pouch, with complications uniformly occurring within months of ileostomy closure. In contrast, 15 of 16 patients without preoperative features of Crohn's disease have maintained their pouch, generally with good results. These data suggest that patients in whom there is clinical and pathologic evidence of Crohn's disease do very poorly without meaningful symptom-free intervals. However, patients without any clinical features of Crohn's disease, despite a histopathologic diagnosis of Crohn's colitis, have had a good outcome with IPAA thus far.
