Abstract
PURPOSE The rectoanal inhibitory reflex has an important role in fecal sampling and discrimination of rectal contents. The aim of this study was to determine the significance of rectoanal inhibitory reflex after restorative proctocolectomy with ileal pouch-anal anastomosis for mucosal ulcerative colitis. METHODS The medical records of 345 patients who underwent ileal pouch-anal anastomosis from September 1988 to May 1999 were retrospectively reviewed. One hundred patients who underwent double-stapled ileal pouch-anal anastomosis and had anorectal physiology testing within 3 months before surgery as well as after ileostomy closure (mean, 23.1; range, 3-77 months) were analyzed. Anorectal physiology testing included detecting the presence of the rectoanal inhibitory reflex, sensory threshold volume, and rectal or pouch capacity and compliance. Parameters to determine incontinence included daytime and nocturnal bowel movement frequency, nocturnal spotting, status of continence for solid or liquid stool, gas, use of pads, and lifestyle alteration were surveyed in 62 of the 100 patients at a mean of 3.9 (range, 1-9.1) years to determine the incontinence score. RESULTS Whereas the rectoanal inhibitory reflex was noted in 96 (96 percent) patients before surgery, it was found in only 53 (53 percent) after ileostomy closure (P < 0.0001). Incontinence status data was available in only 62 of the 100 patients (32 RAIR-positive; 30 RAIR-negative). There were no significant differences between the rectoanal inhibitory reflex-positive and the rectoanal inhibitory reflex-negative groups relative to the interval between surgery and manometry (22 vs 25 months), postoperative threshold sensation volume (32 vs 31 ml), postoperative compliance (19 vs 12 cm H(2)O/ml), postoperative capacity (85 66 ml), daytime/nighttime stool frequency (6.2/2 vs 5.5/1.5), or postoperative incontinence score (3.9 vs 1.8). However, there were significant differences relative to the incidence of nocturnal soiling (12/30 (40 percent) 23/32 (72 percent), P = 0.0012) favoring the presence of the rectoanal inhibitory reflex. CONCLUSION Preservation of the rectoanal inhibitory reflex correlated with a decrease in the incidence of nocturnal soiling after double-stapled ileoanal reservoir construction.

Abstract
Intra-abdominal abscesses are a frequent source of morbidity and mortality following both elective and emergent surgery of the alimentary tract. CT-guided percutaneous drainage of intra-abdominal abscess is an alternative to immediate surgical intervention. We studied the clinical characteristics and outcomes of patients undergoing percutaneous drainage of intra-abdominal abscesses arising after elective colorectal procedures. We retrospectively identified 40 patients with postoperative intraabdominal abscess following elective colorectal surgery who underwent CT-guided percutaneous drainage with a Von Sonnenberg sump drain between 1990 and 1998. The most common presenting symptoms were pyrexia in 39 (97%), abdominal tenderness in 32 (80%), guarding in 1 (2.5%) and abdominal mass in 3 (7.5%); no patient had generalized peritonitis. The most common index procedure was proctocolectomy with ileoanal anastomosis and ileal Jpouch in 12 (30%) patients. Drainage was performed using an anterior approach in 32 (80%) and a transgluteal window in 8 (20%) patients. Thirty-five (87.5%) patients had a single collection, while 2 (5.0%) patients had 2 collections and 3 (7.5%) patients had 3 collections. Thirteen (32.5%) patients had perioperative steroids, 30 (75%) had preoperative antibiotics, and 40 (100%) had postoperative antibiotics. Follow-up at a mean of 35.8 days revealed complete resolution of abscess in 26 (65%) patients; 14 (35%) patients had residual or recurrent abscess successfully treated by repeat drainage in 8 patients and requiring laparotomy in 6. Percutaneous CT-guided abscess drainage is an effective method for treating intra-abdominal abscess following elective colorectal surgery. The primary success was 65% after the first and 85% after a second drainage. In conclusion, this technique should be considered as the treatment of choice in patients with localized intra-abdominal abscess without signs of generalized peritonitis.

Abstract
Anal stenosis (AS) or stricture is defined as the loss of compliant natural elasticity of the anal opening, which then becomes abnormally tight and fibrous. It is a very disabling condition, worsened by the patient's embarrassment, but uncommon. The vast majority of cases are secondary to trauma, iatrogeny, inflammatory diseases, or neoplasia, or occur postradiation. Depending on the severity and level of involvement, AS can be classified as mild, moderate, or severe. Due to the rarity of this pathology and the different referral patterns among institutions, the etiology ranges widely between published reports. There are multiple surgical techniques that have been described for the correction or improvement of AS. Moderate or severe AS is the usual indication for operative treatment.

Abstract
PURPOSE The management of complex perianal fistulas with endorectal advancement flap is aimed at avoiding the risk of sphincter injury associated with traditional surgical methods. Long-term follow-up is required to assess the recurrence and continence outcomes of this procedure. The aim of this study was to review our experience with endorectal advancement flap in the treatment of complex perianal fistulas and to define the predictors of successful healing. METHODS A retrospective chart review of all patients who underwent endorectal advancement flap for complex perianal fistulas between 1988 and 2000 was performed. Follow-up was established by telephone interview. RESULTS One hundred six consecutive endorectal advancement flap procedures were performed on 94 patients (94.4 percent). There were 56 females (59.6 percent). Mean age was 41.6 (range, 18-76) years. Cryptoglandular disease was the most common cause of fistula (n = 41, 43.6 percent), followed by Crohn's disease (n = 28, 29.8 percent). At a mean follow-up of 40.3 (range, 1-149) months, the procedure was successful in 56 (59.6 percent) of 94 patients. Twelve patients underwent repeat surgery with the same technique because of initial failure, 8 of whom eventually healed. Crohn's disease was associated with a significantly higher recurrence rate (57.1 percent) when compared with fistulas in patients without Crohn's disease (33.3 percent, P< 0.04). Prior attempts at repair of the fistula were not associated with less favorable outcome of the procedure (P = 0.5). Recurrence was not associated with the type of fistula, origin, preoperative steroid use, postoperative bowel confinement, use of postoperative antibiotics, or creation of a diverting stoma. The median time to recurrence was 8 (range, 1-156) weeks; there was no postoperative mortality. Two patients had postoperative bleeding, one requiring resuture of the flap on the first postoperative day. Recurrences were observed in 15.7 percent of the patients 3 or more years after the repair. In 8 patients (9 percent), continence deteriorated after the endorectal advancement flap, a more common finding in patients who had undergone previous surgical repairs (P < 0.02). CONCLUSION The success rate of endorectal advancement flap for complex perianal fistulas is modest. Failure is mainly correlated with the presence of Crohn's disease.

Abstract
OBJECTIVES Treatment of severe fecal incontinence (FI) is essentially surgical. However, patients in whom surgery has failed, those who have high operative risks, and those who refuse to undergo surgery are often condemned to living with this embarrassing condition. The Procon incontinence device, a relatively simple, nonsurgical device, may represent a good solution in preventing episodes of FI, thus improving quality of life in these individuals. This device consists of a disposable, pliable rubber catheter with an infrared photo-interrupter sensor and flatus vent holes on the distal tip that is connected to a pager (or "beeper"). The catheter is inserted in the rectum and held in place by a 20-cc capacity cuff, which acts as a temporary mechanical barrier to stool leakage. Stool entering the rectum is sensed by the photo-interrupter sensor, which then alerts the patient to an imminent bowel movement. Voluntary evacuation is accomplished by deflating the balloon and removing the catheter. The aim of this study was to evaluate the efficacy, reliability, and safety of the Procon device in a group of patients with FI. METHODS Patients with significant FI who had undergone anorectal manometry, ultrasound, and electromyography with pudendal nerve terminal motor latency assessment were prospectively entered into this study. The Procon device was used for 14 consecutive days. A quality of life diary and daily log of bowel activity and incontinent episodes were completed before and after the end of the study. RESULTS Seven patients (five female and two male) with a mean age of 72.7 yr (range 39-81 yr) were evaluated. Etiology of incontinence included idiopathic in four patients, sphincter defect in two, and neurological disorder in one patient. There was an overall significant improvement in the quality of life (p < 0.05) and a significant reduction in incontinence scores with the Procon device (p < 0.05). CONCLUSION The Procon is a unique, safe, and promising device that is able to prevent episodes of FI without the need for surgery, thereby improving quality of life. Its role includes use in patients with severe FI who are unfit to undergo surgery, those in whom previous surgical treatments have failed, or those who do not wish to undergo surgery.

Abstract
PURPOSE The aim of this trial was to evaluate the safety, efficacy, and impact on quality of life of the Acticon trade mark artificial bowel sphincter for fecal incontinence. METHODS A multicenter, prospective, nonrandomized clinical trial was conducted under a common protocol. Patients were evaluated with anal physiology, endoanal ultrasonography, a fecal incontinence scoring system, fecal incontinence quality of life assessment, and overall health evaluation. Patients with a fecal incontinence score of 88 or greater (scale, 1-120) were considered candidates for the study. Implanted patients underwent identical reevaluation at 6 and 12 months postimplant. RESULTS One hundred twelve of 115 patients (86 females) enrolled were implanted. Mean age was 49 (range, 18-81) years. A total of 384 device-related or potentially device-related adverse events were reported in 99 enrolled patients. Of these events, 246 required no intervention or only noninvasive intervention. Seventy-three revisional operations were required in 51 (46 percent) of the 112 implanted patients. Infection rate necessitating surgical revision was 25 percent. Forty-one patients (37 percent) have had their devices completely explanted, of which 7 have had successful reimplantations. In patients with a functioning neosphincter, improvement in quality of life and anal continence was documented. Mean matched fecal incontinence scores in 63 patients at 6 months follow-up was improved from 105 preimplant to 51 postimplant. In 55 patients at 12 months follow-up, mean matched fecal incontinence scores were 105 preimplant 48 postimplant. A successful outcome was achieved in 85 percent of patients with a functioning device. Intention to treat success rate was 53 percent. CONCLUSIONS Although morbidity and the need for revisional surgery are high, the artificial bowel sphincter can improve anal incontinence and quality of life in patients with severe fecal incontinence.

Abstract
The diagnosis of significant rectocele is currently made on the basis of cinedefecographic findings. Clinical examination alone will only allow assessment of the presence but not the significance of a rectocele. Therefore, the aim of this study was to determine if anal manometric findings can predict the significance of a rectocele. All patients with a diagnosis of constipation and rectocele confirmed on cinedefecography between 1992 and 1998 were retrospectively reviewed. Significant rectocele was defined as the presence of three of the following five parameters: rectocele >4 cm in diameter as measured during the evacuatory phase of cinedefecography, rectal and/or vaginal symptoms present for longer than 12 months, persistence of rectal or vaginal symptoms for at least four weeks, despite increased dietary fiber (up to 35 g/day), need for rectal and/or vaginal digitation or perineal support maneuvers for rectal evacuation. Statistical analysis was performed using the Mann-Whitney test and Fisher's exact test. A logistic regression model with stepwise selection was used to determine significant prognostic factors. A total of 305 patients (31 men) with rectocele, with a median age of 68 years (range, 12-89) were identified. Of these, 89 (29.2%) had significant rectoceles. There was no difference in the frequency of significant and non-significant rectoceles with respect to gender or age. However, patients with a significant rectocele compared to those with a non-significant rectocele had higher median first sensation volume (45 vs. 30 ml, p=0.0005), median capacity (160 vs. 120 ml, p<0.0001), and median compliance (10 vs. 8 ml H(2)O/mmHg, p=0.05). Calculations based on a logistic regression model determined that with a first sensation of 100 ml, a capacity of 400 ml, and a compliance of 50 ml/mmHg, the probability of a significant rectocele would be 85%. In conclusion, anal manometric findings may be useful in predicting significant rectocele in constipated patients.

Abstract
BACKGROUND In this study, we set out to examine the current attitudes among surgeons toward laparoscopic colorectal surgery (LCS). METHODS A total of 3628 questionnaires were sent to all North American members of the Society of American Gastrointestinal Endoscopic Surgeons (SAGES) and the American Society of Colon and Rectal Surgeons (ASCRS); 40% of the members of each society responded (B15 respondents). RESULTS Currently, 85% of the respondents perform laparoscopic surgery; LCS was performed by 48% of the respondents in 21% of their patients. Although 35% of the members of SAGES have increased the number of laparoscopic colorectal operations they perform in the last 3 years, only 26% of ASCRS members did so. Our findings showed that 74% of the surgeons who perform LCS do so for diverticular disease, 68% for colonic polyps, 61% for villous adenoma, and 36% for ileal Crohn's disease. However, only 15% operate for the cure of carcinoma of any stage (16% of SAGES members and 11% of ASCRS members), whereas 8.5% and 7% operate for the cure of all upper and lower rectal carcinomas, respectively. Thirty-six percent of the surgeons who perform LCS for cancer have done between one and 10 curative resections, 8% have done 11-20 procedures, and 14% have done >20 procedures. There were 80 cases of port site recurrence reported by 4.4% of surgeons. Although 56% of the respondents would themselves undergo laparoscopic colorectal surgery for a rectal villous adenoma, only 9% would do so for a distal-third rectal carcinoma (12% of SAGES and 5% of ASCRS respondents). CONCLUSIONS The overall percentage of respondents performing LCS has decreased over the last 3 years; moreover, surgeons are more hesitant to perform laparoscopic surgery for the cure of colonic cancer. Due to the overall low response rate, the fact that 4.4% of those surgeons who did respond have seen port site recurrences does not allow any conclusions to be drawn about the prevalence of this problem.

Abstract
BACKGROUND The localization of focal colonic pathologies is problematical in laparoscopic surgery because it is difficult to palpate the colon. The aim of this study was to evaluate the use of intraoperative lower endoscopy in laparoscopic segmental colectomy. METHODS We did a retrospective review of the charts of patients who had undergone laparoscopic segmental colectomy. Patients in whom intraoperative lower endoscopy had been used were compared to a group of 250 patients who had colectomy by laparotomy. The patients were matched by type of surgery and operating surgeon. RESULTS Between 1991 and 2000, 233 patients underwent laparoscopic segmental colectomy at our clinic. Lower endoscopy was employed in 57 of them (24%), as compared to 42 patients (17%) in the laparotomy matched group ( p = 0.042). The diseased segment was successfully identified in all of the patients in whom the main indication for endoscopy was localization (65% of cases). Endoscopy was judged to have changed the surgical management in 66% of the 57 cases in whom it was employed, and especially in 88% of the 37 patients for whom the main indication had been localization. There were no endoscopy-related complications. CONCLUSION Intraoperative lower endoscopy is a useful and safe tool for the localization of pathologies and the assessment of the intracorporeal anastomosis in laparoscopic segmental colectomy.

Abstract
PURPOSE As many as 60 percent of patients present with recurrent symptoms of fecal incontinence after anterior overlapping anal sphincter repair. The aim of this study was to assess the outcome of repeat overlapping anal sphincter repair. METHODS All female patients with obstetric sphincter damage who underwent anterior overlapping sphincter repair between November 1988 and June 2000 were reviewed. All patients were preoperatively assessed by anorectal manometry, electromyography, and pudendal nerve terminal motor latency; manometry was repeated during follow-up. Preoperative endoanal ultrasonography was available only after 1990. Clinical outcome was assessed according to the Cleveland Clinic Florida Incontinence Score. RESULTS One hundred fifty-one patients were available for analysis, 115 without previous surgery and 36 after at least one previous sphincter repair. The median follow-up was 13 (range, 1-64) months and 20 (range, 2-96) months, respectively. The median incontinence score improved from 18 to 5 (P < 0.0001) in patients without previous repair and from 17.5 to 7 (P < 0.0001) in patients after previous repair. In the former group, the outcome was good in 67 (58 percent) patients, adequate in 19 (16.5 percent), and poor in 29 (25.5 percent). In the group with previous sphincter repair, the outcome was good in 18 patients (50 percent), adequate in 4 (11 percent), and poor in 14 (39 percent; P = 0.2646). The mean resting pressure increased from 20 (range, 3-43) mmHg to 24 (range, 10-44) mmHg and from 27 (range, 4-56) mmHg to 32 (range, 16-45) mmHg, respectively. The mean squeeze pressure increased from 60 (range, 23-63) mmHg to 67 (range, 33-114) mmHg and from 54 (range, 25-90) mmHg to 70 (range, 34-95) mmHg, respectively. CONCLUSION Previous sphincter repair does not affect clinical outcome. Repeat anterior overlapping sphincter repair yields a significant improvement in the continence score and should be considered as the treatment of choice in patients with fecal incontinence who have had previous sphincter repair and residual anterior sphincter damage.

Abstract
BACKGROUND The aim of this study was to assess the outcome of laparoscopic colorectal surgery in obese patients and compare it to that of a nonobese group of patients who underwent similar procedures. METHODS All 162 consecutive patients who underwent an elective laparoscopic or laparoscopic-assisted segmental colorectal resection between August 1991 and December 1997 were evaluated. Body mass index (BMI; kg/m2) was used as an objective index to indicate massive obesity. The parameters analyzed included BMI, age, gender, comorbid conditions, diagnosis, procedure, American Society of Anesthesiologists classification score, operative time, estimated blood loss, transfusion requirements, intraoperative complications, conversion to laparotomy, postoperative complications, length of hospitalization, and mortality. RESULTS Thirty-one patients (19.1%) were obese (23 males and 8 females). Conversion rates were significantly increased in the obese group (39 vs 13.5%, p = 0.01), with an overall conversion rate of 18%. The postoperative complication rate in the obese group was 78% versus 24% in the nonobese group (p <0.01). Specifically, rates of ileus and wound infections were significantly higher in the obese group [32.3 vs. 7.6% (p <0.01) and 12.9 vs 3.1%. (p = 0.03), respectively]. Furthermore, hospital stay in the obese group was longer (9.5 days) than in the nonobese group (6.9 days, p = 0.02). CONCLUSION Laparoscopic colorectal segmental resections are feasible in obese patients. However, increased rates of conversion to laparotomy should be anticipated and the risk of postoperative complications is significantly increased, prolonging the length of hospitalization when compared to that of nonobese patients.

This study evaluated the incidence and physiological findings in male patients with rectoceles. All defecographic studies were evaluated by a single colorectal surgeon. After diagnosis of rectocele in male patients, the patient's history, symptoms, and physiologic tests (anal manometry, pudendal nerve terminal motor latency [PNTML], assessment and electromyography [EMG]) were studied. A prominent rectocele was defined as one that did not empty during defecography and was associated with outlet obstructive syndrome. Forty (17%) rectoceles were diagnosed in 234 male patients with evacuatory disorders who underwent defecography. Rectoceles were anterior in 19 (48%) and posterior in 21 (52%) patients. The main complaint was constipation with difficult defecation in 33 (83%), followed by rectal pain in 5 (13%), rectal prolapse in 1 (3%), and incontinence in 1 (3%). Previous prostatic surgery had been performed in 16 (40%) patients. The mean age and duration of symptoms were 72.4 years (range, 30-88) and 10.3 years (range, 0.5-70), respectively. Excessive straining during evacuation was noted in 73%, unilateral or bilateral pudendal neuropathy in 24.5%, paradoxical puborectalis contraction in 49% and abnormal EMG in 11% of patients. Higher resting pressures with a mean 3.9 cm high pressure zone were noted in 29% of patients. The accompanying findings in defecography were, non-relaxing or partially relaxing puborectalis muscle (66%), perineal descent (65%), intussusception (23%), and sigmoidocele (15%). None of the patients underwent surgery for rectocele alone. In conclusion, rectocele is uncommon in males; it rarely appears as an isolated dysfunction as it is often associated with functional disorders of the pelvic floor. There is a frequent association between rectocele and prostatectomy. Clinical significance and therapeutic strategy remain unknown.

Abstract
OBJECTIVE The aim was to assess the efficacy of chemoradiation therapy for squamous cell carcinoma of the anal canal in HIV seropositive patients. PATIENTS AND METHODS A retrospective review of all patients with squamous cell carcinoma of the anus treated primarily with combined chemotherapy (5-fluorouracil and mitomycin) and radiotherapy or local excision was undertaken comparing HIV seropositive to HIV seronegative patients. RESULTS Thirteen HIV seronegative patients were compared with 6 HIV seropositive patients. The HIV positive group included a higher proportion of males and a significantly greater history of prior treatment for condyloma. There was no difference in the median radiation dose (5020 cGy vs 4500 cGy, P=0.10). There was a trend towards higher local tumour recurrence in the HIV seropositive patients although this was not statistically significant (30% vs 66%). The CD4 count of HIV positive patients did not correlate either with their ability to complete the prescribed treatment regimen or with subsequent recurrence. CONCLUSION Combined chemoradiation is feasible in HIV positive patients, however, local recurrence rates in HIV positive patients may be higher. Tolerance of this therapy in HIV seropositive patients or recurrence after therapy are not related to the patient's CD4 cell count.

Abstract
PURPOSE The colonic J-pouch technique of reconstruction optimizes functional outcome after proctectomy with coloanal anastomosis. However, the impact of adjuvant chemoradiation therapy on pouch function in rectal cancer patients has not been investigated. METHODS From January 1994 to December 1999, 74 patients with midrectal or low rectal tumors (less than 10 cm from the anal verge) underwent a proctectomy with coloanal anastomosis with colonic J-pouch reconstruction. Chemoradiation was offered in patients with Stage II and III disease. Radiation therapy was administered using a four-field technique including the anal canal, for a total dose of 50.4 Gy (1.8 Gy/fraction/day). Fifteen patients (20 percent) died with metastatic disease, five (6.8 percent) died of other causes without evidence of recurrence, and five (6.8 percent) were lost to follow-up. In addition, two patients had local recurrence (2.7 percent) at the time of follow-up. Forty-five of 47 eligible patients (96 percent) responded to a questionnaire designed to evaluate specifically the degree of continence and pouch evacuation. RESULTS The mean age of patients was 68.9 (range, 42-88) years and the mean duration of follow-up was 28.8 (range, 1-69) months. There were 28 patients in the surgery alone group and 17 patients who received either preoperative (13) or postoperative (4) adjuvant chemoradiation therapy. Patients in the surgery alone group had a significantly better degree of continence (mean +/- standard deviation continence score: 18.1 +/- 2.9 vs. 13.3 +/- 4.1, P < 0.001) and were less likely to experience evacuatory problems (mean +/- standard deviation evacuation score: 21.3 +/- 3.7 vs. 16.4 +/- 3.5, P < 0.001). Use of a pad was more frequent in the chemoradiation therapy than in the surgery alone group (53 vs. 18 percent, P = 0.02). The incidence after functional disorders was also more frequent in the irradiated group of patients: incontinence to gas (76 vs. 43 percent, P = 0.03), to liquid stool (64 vs. 25 percent, P = 0.01), and to solid stool (47 vs. 11 percent, P = 0.01). Moreover, irradiated patients reported more frequent pouch-related specific problems, such as clustering (82 vs. 32 percent, P = 0.001), and sensation of incomplete evacuation (82 vs. 32 percent, P = 0.001). Finally, regression analysis demonstrated that radiation-induced sphincter dysfunction was progressive over time. CONCLUSIONS Both preoperative and postoperative chemoradiation therapy adversely affects continence and evacuation in patients with colonic J-pouch. Because radiation-induced damage to the normal tissues is known to be cumulative over time, long-term progressive dysfunction of the anal sphincter and neorectum are causes of concern. Consideration should be given to excluding the anal canal from the field of irradiation in patients with Stage II and III rectal cancer, whenever a sphincter-preserving procedure is planned.

Abstract
PURPOSE Complications of the ileal pouch with ileoanal anastomosis are associated with poor function and diminished quality of life; often, these complications may require surgery to salvage the pouch. The aims of this study were to review our experience with reoperative ileoanal pouch surgery and to define any predictors of pouch salvage surgery. METHODS Between 1991 and 1999, the medical records of all patients who underwent reoperative ileoanal pouch surgery for either pouch salvage or pouch excision were reviewed; any minor local procedures were excluded. Successful ileoanal pouch salvage was considered to be an intact and functioning pouch, with acceptable patient satisfaction and good control. RESULTS Thirty-two patients underwent reoperative ileoanal pouch surgery, 25 for attempted pouch salvage and 10 for pouch excision (3 patients were included in both groups). Five patients (20 percent) had pouch reconstruction, 1 of which was successful; 8 (32 percent) had pouch advancement, with a 62 percent success rate; and 16 (64 percent) had local perianal procedures for control of perianal sepsis, with a 75 percent success rate (4 of these required further surgery). The overall success rate of ileoanal pouch salvage surgery was 84 percent, with 64 percent of patients having acceptable function. There was no correlation between the number of ileoanal pouch salvage procedures and failure. Four (40 percent) of the 10 patients who had pouch excision were ultimately diagnosed with Crohn's disease. CONCLUSIONS Ileoanal pouch salvage surgery is often successful and, in motivated patients without Crohn's disease, is worthwhile. Pouch advancement or local perianal repair yielded better results than did pouch reconstruction. Patients diagnosed with Crohn's disease after ileoanal pouch construction may be best suited for pouch excision when complications occur.

Abstract
OBJECTIVE Colonic inertia (CI) usually presents in women in the third decade of life; however, elderly patients are at times diagnosed with the disease. Total abdominal colectomy (TAC) is considered the preferred surgical treatment for patients with well established CI refractory to conservative and medical management. Surgeons are reluctant to proceed with colectomy in aged patients because of anticipated high morbidity and poor functional outcome. MATERIALS AND METHODS We retrospectively reviewed the outcome in 14 patients over the age of 65 years (range 65-80) (Group I) who underwent TAC for CI between 1988 and 1996. The functional and clinical outcome was compared with that of 41 patients under the age of 65 (range 21-61) (Group II) operated upon during the same time period. Functional outcome was assessed by postal and telephone questionnaires at least 12 months following surgery. RESULTS There was no major postoperative morbidity in either group. Three (21%) patients in Group I developed small bowel obstruction postoperatively and, of them, 2 required surgical treatment. In Group II the rate of obstruction was 7% (3 patients), with one patient requiring surgery. One patient in Group I subsequently underwent completion proctectomy and creation of an end ileostomy due to continued panenteric hypomotility. Three patients in Group I died during follow-up from causes unrelated to surgery. The mean frequency of spontaneous bowel movements following surgery was 3.8 (range 1-10)/day in Group I and 2.9 (range 1-8)/day in Group II (P=NS). 'Excellent' outcome was reported by 7 patients (64%) in Group I and 39 patients (95%) in Group II (P=0.01). CONCLUSION TAC can be performed in elderly patients with established CI with acceptable functional results and no increase in morbidity, resulting in lifestyle improvement. Complete physiological evaluation with increased emphasis on small bowel and gastric motility studies is required in this patient population.

Abstract
PURPOSE The aim of this study was to determine the prevalence, severity, and associations between urinary incontinence and genital prolapse in females after surgery for fecal incontinence or rectal prolapse. METHODS All patients who underwent surgery for fecal incontinence (Group I) or rectal prolapse (Group II) were compared with a control group of females (Group III) by 43 questions regarding demographic data, past medical and surgical history, and diagnosis and treatment of anal and urinary incontinence and genital and rectal prolapse. The type (stress, urge, and total) of urinary incontinence was determined and graded using an incontinence severity questionnaire (Individual Incontinence Impact Questionnaire). RESULTS Overall response rate in the three groups of patients was 40.1 percent. The questionnaire was sent to 240 patients operated on for fecal incontinence or rectal prolapse, and 83 of them responded (34.5 percent). The patients were distributed into three groups: Group I consisted of 51 patients (mean age 56.7 +/- 14); Group II consisted of 32 patients (69.7 +/- 11); and Group III consisted of 40 patients (60.5 +/- 16). The prevalence of urinary incontinence in Group I was 27 (54 percent), in Group II was 21 (65.6 percent), and Group III was 12 patients (30 percent; P = 0.003). Genital prolapse was present in 9 (17.6 percent), 11 (34.3 percent), and 5 patients (12.5 percent), respectively (P = 0.03). The prevalence of coexistent urinary incontinence and genital prolapse in both study groups was 22.8 percent (19 patients). There were no statistically significant differences between Groups I and II relative to prevalence, type, and severity of urinary incontinence and genital prolapse, but there were significant differences between the two study groups and the control group. Of the patients in the study group, 67 percent had urinary incontinence before or at the time of surgery. CONCLUSION There is a higher prevalence and severity of urinary incontinence and pelvic genital prolapse in females operated on for either fecal incontinence or rectal prolapse than in a control group. Therefore, female patients with fecal incontinence or rectal prolapse should be evaluated and treated by a multidisciplinary group of pelvic floor clinicians, including a gynecologist or urologist with special training in female pelvic floor dysfunction and a colorectal surgeon.

Abstract
BACKGROUND Obesity is a relative contraindication to performing restorative proctocolectomy. The aim of this study was to assess the morbidity and functional results after restorative proctocolectomy in obese patients as compared to a matched cohort of non-obese patients. METHODS 334 patients who had restorative proctocolectomy were reviewed; obesity was defined as a body mass index (BMI) greater than or equal to 30 kg/m2. 31 obese patients were matched to 31 non-obese patients for age, gender, steroid use, and diagnosis. Operative time, length of hospitalization, and both perioperative (< 6 weeks) and long-term morbidity (> 6 weeks), especially sepsis, were evaluated. RESULTS The BMI was significantly higher in the obese group (33.7 vs 23.2) (p < 0.0001), and no difference was found between the obese and non-obese groups relative to the matched parameters of age, gender, steroid use and diagnosis. There was no difference in the rate of mucosectomy performed between the obese and non-obese patients (9.6% vs 3.2%, p = NS). 16% of the obese patients underwent one stage restorative proctocolectomies as compared to 10% in the non-obese group. Operative time was longer in the obese group (229 min vs 196 min; p = 0.02), but overall hospital length of stay was similar (9.7 days vs 7.7 days; p = 0.13). Perioperative morbidity was higher in obese patients (32% vs 9.6%, p = 0.058). However, there was no statistical significance in long-term morbidity (23% vs 32%, p = 0.57) at a mean follow-up of 51 months in the obese group and 53 months in the non-obese group. Obese patients had more stomal complications (10 vs 0%) and incisional hernias (13 vs 3%) (p = NS). Overall the pelvic sepsis-rate was significantly higher in the obese group (16 vs 0%; p < 0.05). 60% of the obese patients who developed pelvic sepsis had pouch-anal anastomosis performed without proximal fecal diversion. Mean bowel movements/24 hours, pad use, nocturnal evacuation, accidents/24 hours and incontinence scores were not statistically significant between the groups. CONCLUSION Obese patients have a higher rate of pelvic sepsis and peri-operative morbidity when compared to a matched non-obese cohort of patients; however, the functional outcome of restorative proctocolectomy in obese patients is not significantly different than in non-obese patients.

Abstract
PURPOSE This study was designed to describe a surgical technique for the treatment of circumferential Paget's disease. METHODS A search of our computerized patient registry was undertaken, and case records for those patients with perianal Paget's disease were systematically reviewed. RESULTS Between July 1993 and October 1998, four patients with perianal Paget's disease were identified. Circumferential lesions were identified in three of the four patients. Wide local excision was considered the procedure of choice. All patients underwent a two-staged excision using split-thickness skin graft reconstruction. A similar second stage was performed six to eight weeks later; the other half of the circumference was excised and grafted. No patient had a protective stoma. Graft survival was 100 percent for two patients (four operations) and 80 percent and 70 percent for the other two patients (two operations). The remaining surface healed successfully by secondary intention. In one patient, residual disease was positive at one margin, and a third local excision and split-thickness skin graft was performed. Hospital stay ranged from five to nine days for each procedure. There were no major complications; one patient developed a mild anal stenosis three months after the second procedure and was successfully medically treated. CONCLUSIONS Staged excision and split-thickness skin graft is a viable option for the treatment of circumferential perianal lesions. It carries a minimal morbidity and no observed mortality, the functional result is good, and it is technically simple compared with myocutaneous grafts. Moreover, a stoma is not required.

Abstract
PURPOSE The aim of the study was to assess the impact of sodium hyaluronate and carboxymethylcellulose membrane (Seprafilm) on postoperative intestinal obstruction as judged by the rates of bowel obstruction and laparotomy for bowel obstruction. A secondary aim was to assess early postoperative morbidity. METHODS All patients who had Seprafilm placed during colorectal surgery between June 1993 and October 1998 were included in the study group and compared with a matched group of patients without Seprafilm. All patients were assessed for intestinal obstruction and complications by telephone interview and chart review. Statistical tests for independence were used where appropriate; alpha was 0.05 for all tests, and the two groups were tested for case matching. Fisher's exact test was used to compare gender distribution, nature of diagnosis (inflammatory vs. noninflammatory), and urgency of surgery (elective vs. emergency). The age distribution, number of prior abdominal surgeries, and operative time were compared by Student's t-test. Approximation of Katz test was used for independent proportions to compare the two groups for early postoperative morbidity and overall incidence of intestinal obstruction and surgical enterolysis. The incidence of intestinal obstruction between the two groups was also compared with Kaplan-Meier product limit method and log-rank test. RESULTS Two hundred fifty-nine patients in whom Seprafilm was placed were compared with a well-matched control cohort of 179 patients. The two groups did not differ in gender or age. One-half of each group had inflammatory conditions, and approximately 90 percent of each group underwent elective operations. The operative times were similar. Both groups had a similar number of abdominal operations before inclusion (mean = 1.2, both groups). Early morbidity rates were 17.8 percent for the Seprafilm group and 15.6 percent for the controls, with mortality rates of 0.8 percent and 0.0 percent, respectively. There were 12 intestinal obstructions in 12 patients in the Seprafilm group and 12 intestinal obstructions in 11 patients in the control group at a follow-up period of 65 months in the Seprafilm group and 81 months in the control group. Eight of the 12 intestinal obstructions in the Seprafilm group resolved with conservative management while only 5 of 12 in the control group responded without surgery. Thus the enterolysis rate was 1.5 percent in the Seprafilm group and 3.9 percent in the control group, demonstrating a trend in favor of Seprafilm. There were no statistically significant differences in the incidence of either overall or abdominopelvic septic complications between the Seprafilm (3.4 percent) and control (1.1 percent) groups. CONCLUSION During short-term follow-up in this nonprospective, nonrandomized study, limited placement of Seprafilm did not significantly reduce the need for surgical enterolysis for intestinal obstruction or significantly adversely affect the morbidity rate. However, a long-term, prospective, randomized trial is underway to elucidate these issues.

Abstract
The aim of this study was to compare the morbidity of subtotal colectomy with ileorectal anastomosis performed for colonic inertia, Crohn's disease, familial adenomatous polyposis, and colorectal neoplasia. A retrospective review of all patients who underwent elective colectomy with ileorectal anastomosis between June 1988 and November 1996 was performed. The patients were divided into three groups: Group I, colonic inertia; Group II, Crohn's disease; and Group III, Familial Adenomatous Polyposis or other neoplasia. Outcome factors studied included the frequency of bowel movements, the incidence of small bowel obstruction, and the incidence of anastomotic leakage. Other factors assessed included operative time, intraoperative blood loss, length of hospitalization, level of ileorectal anastomosis, time of first bowel movement, and whether the operation was undertaken in one or two stages. Statistical analysis was undertaken by using the chi-square test and the Mann-Whitney U exact test. All 48 patients in Group I were operated on in one stage. In Group II (30 patients) 15 patients were operated on in one stage, eight patients had a preliminary Hartmann's operation and then ileorectal anastomosis, and seven patients underwent subtotal colectomy with both an ileorectal anastomosis and a proximal loop ileostomy. In Group III (22 patients) 20 patients underwent a one-stage operation whereas two patients underwent a subtotal colectomy with ileorectal anastomosis and proximal loop ileostomy. The median ages were 47.0 years in Group I, 43.8 in Group II, and 53.3 in Group III. Small bowel obstruction occurred in five patients (10%) in Group I, four patients (13.3%) in Group II, and four patients (18%) in Group III. The anastomotic leak rate was 4.2% (two patients) in Group I, 1% (three patients) in Group II, and 0% in Group III (P < 0.05). At the follow up interview after surgery, the mean number of bowel movements per day 6 months after surgery was 5.4 in Group I, 7.2 in Group II, and 5.6 in Group III, (P < 0.05, Group II vs Group I or Group III). Operative time in Group III was significantly longer than in the other two groups (P = 0.004). No statistically significant differences were found among the three groups relative to blood loss, hospitalization, or timing of first bowel movement. This study failed to identify any differences in either immediate perioperative outcome or morbidity or intermediate-term function in patients undergoing ileorectal anastomosis regardless of diagnosis. The overall rate of small bowel obstruction was 13 per cent with no significant differences among the three groups. Lastly although the anastomotic leak rate was not significantly higher in patients with Crohn's disease it was higher in the group with ileostomy and ileorectal anastomosis, which highlights a potential advantage of performance of this procedure in two stages in selected patients of this patient population.

Abstract
PURPOSE This study attempts to compare the diagnostic efficacy of dynamic pelvic magnetic resonance imaging with that of videoproctography for the presence of rectocele, sigmoidocele, and intussusception as well as the measurement of anorectal angle and perineal descent in constipated patients. METHODS Patients volunteering for the study and fulfilling the criteria for videoproctography to evaluate constipation were also scheduled for dynamic pelvic magnetic resonance imaging. Patients undergoing videoproctography were placed in the left lateral decubitus position, after which 50 ml of liquid barium paste was introduced into the rectum. After this, approximately 100 ml of thick barium paste similar to stool in consistency was injected into the rectum, and the patient was instructed to defecate while video images were taken. For dynamic pelvic magnetic resonance imaging, air, to be used as contrast, was allowed to accumulate in the rectum via examination with the patient in the prone position. A capsule was taped to the perineal skin immediately posterior to the anal orifice for marking. Sagittal and axial T1 images were obtained through the pelvis at 8-mm intervals with dynamic breathhold sagittal images of the anorectal region obtained at rest and during strain and squeeze maneuvers. Total acquisition time per maneuver was approximately 19 seconds. The tests were performed by different examiners blinded to the result of the other evaluation. The investigations were independently interpreted, findings compared, and patients questioned regarding their impression of dynamic pelvic magnetic resonance imaging and videoproctography. RESULTS From June 1996 to April 1997, 22 patients (15 females) with a mean age of 68 (range, 21-85) years underwent both videoproctography and dynamic pelvic magnetic resonance imaging. Dynamic pelvic magnetic resonance imaging was only able to detect 1 of 12 (8.3 percent) anterior rectoceles and one of two (50 percent) posterior rectoceles identified by videoproctography. It failed to recognize any of the rectoanal intussusception (zero of four) but did show 9 of 12 (75 percent) sigmoidoceles. Significant discrepancy of measurement of the anorectal angle and perineal descent exists between the two studies, and dynamic pelvic magnetic resonance imaging was not able to detect any (0 of 11) of the patients with increased fixed perineal descent and only half (one of two) of the patients with increased dynamic perineal descent noted on videoproctography. All 22 patients preferred dynamic pelvic magnetic resonance imaging over videoproctography because of greater comfort. CONCLUSION Occasionally, the increased cost of new technology can be justified by the enhanced diagnostic yield. The ability to avoid unnecessary surgery or, conversely, to continue to search for otherwise occult pathology that can be surgically corrected justifies routine application of these new tools. However, this study has shown that, despite a cost of approximately ten times more for dynamic pelvic magnetic resonance imaging than for videoproctography, no clinical changes were made. Thus, on the basis of this study, we cannot endorse the routine application of dynamic pelvic magnetic resonance imaging for the evaluation of constipated patients. In certain selected individuals, it may play a role, but further study is necessary to clarify its exact role.

Abstract
OBJECTIVES Rectoanal intussusception is the funnel-shaped infolding of the rectum, which occurs during evacuation. The aims of this study were to evaluate the risk of full thickness rectal prolapse during follow-up of patients with large rectoanal intussusception, and whether therapy improved functional outcome. METHODS Between September 1988 and July 1997, patients diagnosed with a large rectoanal intussusception by cinedefecography (intussusception > or = 10 mm, extending into the anal canal) were retrospectively evaluated. Patients with full thickness rectal prolapse on physical examination or cinedefecography were excluded, as were patients with colonic inertia or a history of surgery for rectal prolapse. The patients were divided into three groups according to the treatment received: group I, conservative dietary therapy; group II, biofeedback; and group III, surgery. Outcomes were obtained by postal questionnaires or telephone interviews. Parameters included age, gender, past medical and surgical history, change of bowel habits, fecal incontinence score, and development of full thickness rectal prolapse. RESULTS Of the 63 patients, 18 were excluded (seven patients had confirmed full thickness rectal prolapse, four had previous surgery for rectal prolapse, three had colonic inertia, and four died). Follow-up data were obtained in 36 (80%) of the remaining 45 patients. The mean follow-up of this group was 45 months (range, 12-118 months). There were 34 women and two men, with a mean age of 72.4 yr (range, 37-91 yr). The mean size of the intussusception was 2.2 cm (range, 1.0-5.0 cm). The patients were classified as follows: group I, 13 patients (36.1%); group II, 13 patients (36.1%); and group III, 10 patients (27.8%). Subjectively, symptoms improved in five (38.5%), four (30.8%), and six (60.0%) patients in the three groups (p > 0.05). Among the patients with constipation, the decrease in numbers of assisted bowel movements per week (time of diagnosis to present) was significantly greater in group II compared to group 1 (8.1+/-2.8 vs 0.8+/-0.5, respectively, p = 0.004). Among the patients with incontinence, incontinence scores improved more in group II as compared to either group I or group III (time of diagnosis to present, 3.7+/-4.2 to 1.1+/-5.4 vs 1.4+/-2.2, respectively, p > 0.05). Six patients (two in group I, three in group II, and one in group III) had the sensation of rectal prolapse on evacuation; however, only one patient in group I developed full thickness rectal prolapse. CONCLUSIONS This study demonstrated that the risk of full thickness rectal prolapse developing in patients medically treated for large intussusception is very small (1/26, 3.8%). Moreover, biofeedback is beneficial to improve the symptoms of both constipation and incontinence in these patients. Therefore, biofeedback should be considered as the initial therapy of choice for large rectoanal intussusception.
