Abstract
AIM Crohn's anal fistula (CAF) is a complex condition, with no agreement on which patient characteristics should be routinely reported in studies. The aim of this study was to develop a core descriptor set of key patient characteristics for reporting in all CAF research. METHOD Candidate descriptors were generated from published literature and stakeholder suggestions. Colorectal surgeons, gastroenterologists and specialist nurses in inflammatory bowel disease took part in three rounds of an international modified Delphi process using nine-point Likert scales to rank the importance of descriptors. Feedback was provided between rounds to allow refinement of the next ratings. Patterns in descriptor voting were assessed using principal component analysis (PCA). Resulting PCA groups were used to organize items in rounds two and three. Consensus descriptors were submitted to a patient panel for feedback. Items meeting predetermined thresholds were included in the final set and ratified at the consensus meeting. RESULTS One hundred and thirty three respondents from 22 countries completed round one, of whom 67.0% completed round three. Ninety seven descriptors were rated across three rounds in 11 PCA-based groups. Forty descriptors were shortlisted. The consensus meeting ratified a core descriptor set of 37 descriptors within six domains: fistula anatomy, current disease activity and phenotype, risk factors, medical interventions for CAF, surgical interventions for CAF, and patient symptoms and impact on quality of life. CONCLUSION The core descriptor set proposed for all future CAF research reflects characteristics important to gastroenterologists and surgeons. This might aid transparent reporting in future studies.

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

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

Abstract
Abstract
Background
The purpose of this study was to determine the long-term outcomes of patients undergoing endocavitary contact radiation therapy (ECR) for stage I rectal cancer.
Methods
A database of patients treated with ECR for biopsy-proven rectal adenocarcinoma from July 1986 to June 2006 was reviewed retrospectively. Only patients with primary, non-metastatic, ultrasonographically staged T1 N0 and T2 N0 cancer who had no adjuvant treatment were included. Patients received a median of 90 (range 60–190) Gy contact radiation, delivered transanally by a 50-kV X-ray tube in two to five fractions.
Results
Of 149 patients, 77 (40 T1, 37 T2) met the inclusion criteria. Median age was 74 (range 38–104) years, and median follow-up 69 (range 10–219) months. ECR failed in 21 patients (27 per cent) (persistent disease, four; recurrence, 17), of whom ten remained disease free after salvage therapy. The estimated 5-year disease-free survival rate was 74 (95 per cent confidence interval 63 to 83) per cent after ECR alone, and 87 (76 to 93) per cent when survival after salvage therapy for recurrence was included.
Conclusion
ECR is a minimally invasive treatment option for early-stage rectal cancer. However, similar to other local therapies, ECR has a worse oncological outcome than radical surgery.

Abstract
Abstract
Background
The aim was to measure female sexual function after total proctocolectomy with ileal pouch–anal anastomosis for ulcerative colitis using a validated scoring system and to determine the impact of pouch function on sexual function.
Methods
A cross-sectional survey was performed using a modified version of the Female Sexual Function Index (FSFI-m). Measures of pouch function, including the Faecal Incontinence Severity Index, were also evaluated.
Results
Of 166 women eligible for inclusion, 90 responded to the questionnaires and 83 of these reported sexual activity. The mean age of the 83 women was 38·4 years and the mean time since pouch formation was 6·2 years. Thirty-nine women (47·0 per cent) had an FSFI-m score of 26 or less, indicating sexual dysfunction. The association between sexual dysfunction and stool leakage interfering with the ability to enjoy sexual activity tended toward significance (P = 0·071), but other measures of pouch function were not associated with sexual dysfunction. Some 55–80 per cent of respondents perceived no change or improved performance in the six domains of sexual function.
Conclusion
Almost half of the respondents reported having sexual dysfunction. Although poor pouch function was not identified as an important predictor of sexual dysfunction in this series, larger studies may be required to identify associated prognostic factors clearly.

Abstract
BACKGROUND Anal fissure is one of the most common anorectal conditions encountered in clinical practice. Most patients experience anal pain with defecation and minor bright red rectal bleeding, allowing a focused history to direct the evaluation. METHODS A systematic medical literature search of NIH, Pubmed, and MEDLINE using the search terms anal fissure, sphincterotomy, anal surgery and anal fissure medical therapy. English language was not a restriction. Cited references were used to find additional studies. RESULTS No single treatment is the best choice for all patients. Because pharmacological therapy is not associated with permanent alterations in continence, a trial of either a topical sphincter relaxant or botulin toxin injection, along with adequate fluid and fibre intake, is a reasonable option. However, because pharmacological therapy has lower healing and higher relapse rates, surgery can be offered in the first instance to patients without incontinence risk factors who have severe, unrelenting pain and are willing to accept a small risk of incontinence, for the highest likelihood of prompt healing and the lowest risk of recurrence. CONCLUSIONS Both non-operative and operative approaches currently exist for the management of anal fissure. Improved non-surgical therapies may continue to lessen the role of sphincter-dividing surgery in future.

Abstract
OBJECTIVE The purpose of this article is to review the surgical management and outcome of toxic megacolon and to update the aetiology of toxic megacolon. PATIENTS AND METHOD A retrospective chart review of three academic colorectal surgery units was undertaken. Over a period of 20 years, 70 patients with surgically managed toxic megacolon were identified: 32 men and 38 women, median age 63 years (range, 23-87 years). RESULTS In 33 (48%) patients the main cause of toxic megacolon was inflammatory bowel disease. Thirty-seven (52%) patients had toxic megacolon of different aetiology. Sixty-three patients underwent colonic resection: 49 (70%) subtotal colectomies and 14 (20%) total colectomies, including 4 (6%) proctocolectomies. Seven (10%) patients had decompression (n=3) or faecal diversion (n=4) only. Forty-four of the resected patients underwent a Hartmann's procedure and an ileostomy; 13 (19%) patients had primary anastomoses, 11 (16%) ileorectal anastomoses (IRA) and 2 (3%) patients had ileal pouch-anal anastomosis (IPAA). Twenty-six (37%) patients subsequently had continuity restored. Total surgical complication rate was 19% (n=13), 8% (n=4) in patients treated with subtotal colectomy, 21% (n=3) in patients treated with total proctocolectomy and 86% (n=6) in patients treated with either decompression or diversion. The total mortality rate was 16% (n=11). CONCLUSIONS Toxic colitis complicated by toxic megacolon can occur after various diseases of the colon and remains a life-threatening disorder associated with a significant risk of postoperative complications. Subtotal colectomy with ileostomy remains the procedure of choice. Surgical colonic decompression with faecal diversion alone is associated with a high rate of complications.

Abstract
OBJECTIVE Chemotherapy and radiation (C-XRT) is the first-line therapy for epidermoid carcinomas of the anal canal (ECAC). Treatment failure occurs in up to 33% of patients. Salvage-abdominoperineal resection (APR) is the treatment of choice for locoregional failure but pre-operative radiation may increase wound complications. The purpose of this study was to evaluate patient survival and wound complications after salvage-APR for C-XRT failure. METHODS We reviewed the clinical records of all patients who failed initial C-XRT for ECAC diagnosed between 1992 and 2002. We evaluated patient demographics, treatment, tumour characteristics, survival and postoperative complications. RESULTS Nineteen patients were identified. The mean age at diagnosis was 55 years. Eight (42%) patients had persistent disease; 11 (58%) had tumour recurrence. APR was performed in 15 patients. Perineal wound complications occurred in 12 (80%) patients; half were major complications. Primary flap reconstruction at time of APR was performed in 5 (33%) patients; 2 experienced major wound complications. Overall-survival after salvage APR was 40% (6/15) and disease-free survival was 47% (7/15) at a median follow-up of 14 months (range 2-95 months). Recurrence after salvage-APR occurred in 7 (47%) patients at a median follow-up of 5 months (range 3-19 months). Kaplan-Meier survival analysis showed an advantage for recurrent over persistent disease with 2-year and 5-year survival rates of 75%vs 34% and 28%vs 0%, respectively. CONCLUSIONS Failure of C-XRT for ECAC is associated with a poor prognosis. Although salvage APR may be curative in some patients, perineal wound complications are frequent and primary flap reconstruction is not reliable.

Abstract
PURPOSE This study was designed to analyze the outcome for patients with isolated local recurrence after radical treatment of rectal cancer and to identify predictors of curative resection. METHODS The medical records of 87 patients who developed isolated local recurrence after curative radical surgery for primary rectal cancer were retrospectively reviewed. Survival rates from the time of recurrence were calculated using the Kaplan-Meier method. Tumor stage and histology, patient characteristics, and treatment variables were analyzed using logistic regression to identify predictors of curative surgery. RESULTS Symptomatic treatment alone or chemotherapy and/or radiation therapy was provided to 23 patients (26 percent), and surgical exploration was performed in 64 patients. In 22 patients (25 percent), the tumor was considered unresectable at surgery (n = 13) or was resected for palliation with gross or microscopic positive margins (n = 9). In 42 patients (48 percent), curative-intent resection was performed. The only independent predictors of resectability were younger age at diagnosis, earlier stage of the primary tumor, and initial treatment by sphincter-saving procedure. There was no difference in survival between patients who had no surgery and those who had palliative surgery. The estimated five-year survival rate for patients who had curative-intent resection was better than for those who had no surgery or palliative surgery (35 vs. 7 percent; P = 0.01). Of the 42 patients who underwent curative-intent resection, 14 (33 percent) developed a second recurrence at a mean of 15 +/- 11 months after reoperation. Twenty-five percent of patients developed major complications. CONCLUSIONS Salvage surgery for locally recurrent rectal cancer may be helpful in a selected group of patients. The stage and treatment of the primary tumor may help to identify patients with the best chance for curative-intent resection.

Abstract
PURPOSE An aggressive surgical approach with en bloc resection of involved structures is often possible with anterior rectal cancers that invade adjacent visceral organs, but is rarely possible in tumors that invade the pelvic wall. However, most staging systems include both situations in the same group of T4 rectal cancers. We performed a retrospective study of patients with stage T4 rectal cancer undergoing surgery to assess the influence of different organ involvement on resectability and survival. METHODS A retrospective review was conducted of 84 patients with T4 rectal cancer treated at the University of Minnesota and affiliated hospitals over a ten-year period. Forty-seven patients (56 percent) were staged for local invasion on the basis of final pathology, 19 (23 percent) on the basis of operative findings, and 18 (21 percent) on the basis of ultrasound images. Patients were divided into two groups, those with or without pelvic wall involvement. Resectability, local control, and overall survival were compared between groups. Survival curves were estimated by the Kaplan-Meier method and compared by log-rank test. Multivariate analysis was performed with Cox proportional and logistic regression. RESULTS Thirty-one patients (37 percent) had involvement of the pelvic wall, whereas 53 patients (63 percent) had visceral involvement only. All 29 patients with distant metastasis died of their disease. Forty-seven of the 55 patients without distant metastasis underwent tumor resection. Age and pelvic wall involvement were the only two factors independently associated with the probability of resection in logistic regression analysis (P = 0.0067 and P = 0.037, respectively). The only factor that affected median survival in patients without distant metastasis was tumor resection (49.1 months for resection vs. 6.1 months for no resection, P = 0.017). Patients with visceral involvement had a longer median survival (49.2 months) than those with pelvic wall involvement (13.2 months), but the difference did not reach statistical significance (P = 0.058). CONCLUSION Rectal cancers with pelvic and visceral involvement have different rates of resectability and median survival. These differences should be reflected in the TNM classification system.

Abstract
PURPOSE Dynamic graciloplasty can improve continence in patients with severe refractory fecal incontinence, but associated morbidity is high. The purpose of this study was to identify complications associated with dynamic graciloplasty and to characterize their treatment and impact on patient outcome. METHODS In 121 patients enrolled in a prospective trial of 20 centers and eligible for safety analysis, all complications of dynamic graciloplasty were recorded at the time of their occurrence and followed up until resolution. Severe treatment-related complications were defined as those requiring hospitalization or surgical intervention. RESULTS In 93 patients, 211 complications occurred. Of these, 89 (42 percent) in 61 patients were classified as severe treatment-related complications and resulted from the following: major infection, 19; minor infection, 10; thromboembolic events, 3; device performance and use, 13; pain, 16; noninfectious gracilis problems, 8; noninfectious wound-healing problems, 3; other surgery-related complications, 3. In addition, severe treatment-related complications resulted from constipation in ten and stoma creation or closure in ten. The recovery rate (full or partial) was 87 percent overall, and for severe treatment-related complications, was 92 percent. Of the types of complications, only major infections had an adverse effect on outcome. CONCLUSION Severe complications occur frequently after dynamic graciloplasty, but are usually treatable. They often require one or more reoperations and can lead to significant delays in completion of therapy. In most cases therapy can be salvaged.

Abstract
PURPOSE Preoperative anorectal physiology studies have become part of the standard evaluation of fecal incontinence. This study was undertaken to see whether anorectal physiology results predicted surgical outcome after anterior sphincteroplasty. METHODS Between 1985 and 1994, 191 females with a mean age of 37 (range, 20-74) years underwent anterior sphincteroplasty for anal sphincter disruption. A follow-up questionnaire was sent to all patients, and there were 158 respondents (83 percent). Mean follow-up was 43 (range, 6-120) months. Obstetric injuries accounted for incontinence in 91 percent of the 158 patients who responded to the questionnaire. Mean duration of incontinence was 4.2 years (range, 3 months-51 years) before surgery. Preoperatively, patients were incontinent to solid stool (53 percent), liquid stool (33 percent), gas (3 percent), and unspecified (11 percent). RESULTS Subjectively, the results were as follows: 129 patients (82 percent) improved, 17 (11 percent) were initially improved but subsequently deteriorated, 7 (4 percent) were unchanged, and 5 (3 percent) were worse. Objectively, postoperative continence was classified as follows: excellent (normal) in 23 percent, good (incontinent to gas or minor stain) in 39 percent, fair (incontinent to stool an average of less than once per month) in 26 percent, and poor (incontinent to stool an average of greater than once per month) in 12 percent. Preoperative continence level (incontinent to solid vs. liquid stool) was predictive of postoperative continence classification. Preoperative anorectal manometry was not predictive of clinical outcome (n = 128). There was no significant difference in postoperative continence classification among patients with normal, unilaterally abnormal, and bilaterally abnormal pudendal latency (n = 89). CONCLUSIONS Clinical rather than manometric assessment predicts continence after anterior sphincteroplasty.

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

Abstract
Poor survival in patients following resection for early stage colorectal cancer is thought to be due in part to the presence of occult micrometastases at the time of surgery. The MUC2 mucin gene is highly expressed in the colon and associated colorectal tumors and may be a candidate marker for colorectal cancer micrometastases. We have used RT-PCR to detect expression of MUC2 mRNA transcripts in order to identify possible lymph node micrometastases in node negative (Stage I and II, or Dukes A and B) colorectal cancer patients. A total of 396 nodes (histologic stage N0) from 34 colon and nine rectal cancers were studied by RT-PCR analysis with nested primers for MUC2 (an average of 7.6 nodes per case). In the primary tumors, 42/43 (98.1%) were positive for MUC2 by RT-PCR. Evidence of the presence of MUC2 was demonstrated in nodes from 0 of 10 (0%) patients with Tis or T1, one of six (16.7%) from T2, 10 of 25 (40.0%) from T3, and one of two (50%) from T4 tumors. MUC2 RT-PCR was negative in six nodes from three patients with non-malignant colon disease and positive in histologically positive lymph nodes from six of six (100%) stage III colon cancers. In this study, using RT-PCR to detect the presence of MUC2 transcripts, we have found preliminary evidence for possible micrometastatic disease in approximately a third of histologically negative N0 colorectal cancer patients. The increased presence of MUC2 expression also correlated with more advanced T stage. We conclude that MUC2 RT-PCR may be a sensitive and specific marker for occult micrometastases. This technique has the potential to identify a group of colorectal cancer patients at risk for early cancer recurrence.

Abstract
PURPOSE Dynamic graciloplasty has been used for intractable fecal incontinence, and good results have been reported. The aim of this study was to assess prospectively the safety and efficacy of dynamic graciloplasty for intractable fecal incontinence in a prospective, multicenter trial. METHODS A total of 123 adults were treated with dynamic graciloplasty at 20 institutions. Continence was assessed preoperatively and postoperatively by use of 14-day diaries. RESULTS There was one treatment-related death. One hundred eighty-nine adverse events occurred in 91 patients (74 percent). Forty-nine patients (40 percent) required one or more operations to treat complications. One hundred seventy (90 percent) events were resolved. Sixty-three percent of patients without pre-existing stomas recorded a 50 percent or greater decrease in incontinent events 12 months after dynamic graciloplasty, and an additional 11 percent experienced lesser degrees of improvement. Twenty-six percent were not improved, worsened, or exited. In patients with pre-existing stomas, 33 percent achieved successful outcomes at 12 months. This number increased to 60 percent at 18 months. Seventy-eight percent of patients had increased enema retention time, and mean anal canal pressures improved significantly at 12 months. Significant changes in quality of life were also observed. CONCLUSIONS Objective improvement can be demonstrated in the majority of patients with end-stage fecal incontinence treated with dynamic graciloplasty. Reduction in incontinence episodes can be correlated with improved quality of life. Adverse events are frequently encountered, but most resolve with treatment.

Abstract
OBJECTIVE To evaluate the results of local excision alone for the treatment of rectal cancer, applying strict selection criteria. BACKGROUND DATA Several retrospective studies have demonstrated that tumor control in properly selected patients with rectal cancer treated locally is comparable to that observed after radical surgery. Although there is a consensus regarding the need for patient selection for local excision, the specific criteria vary among centers. METHODS The authors reviewed 82 patients with T1 (n = 55) and T2 (n = 27) rectal cancer treated with transanal excision only during a 10-year period. At pathologic examination, all tumors were localized to the rectal wall, had negative excision margins, were well or moderately differentiated, and had no blood or lymphatic vessel invasion, nor a mucinous component. End points were local and distant tumor recurrence and patient survival. RESULTS Ten of the 55 patients with T1 tumors (18%) and 10 of the 27 patients with T2 tumors (37%) had recurrence at 54 months of follow-up. Average time to recurrence was 18 months in both groups. Seventeen of the 20 patients with local recurrence underwent salvage surgery. The survival rate was 98% for patients with T1 tumors and 89% for patients with T2 tumors. Preoperative staging by endorectal ultrasound did not influence local recurrence or tumor-specific survival. CONCLUSION Local excision of early rectal cancer, even in the ideal candidate, is followed by a much higher recurrence rate than previously reported. Although most patients in whom local recurrence develops can be salvaged by radical resection, the long-term outcome remains unknown.

Abstract
PURPOSE Anal sphincter replacement offers a new treatment option for patients with severe refractory fecal incontinence or for those who require abdominoperineal resection for localized malignancy. The purpose of this study was to review the current status of anal sphincter replacement, formulate a consensus statement regarding its current use, and outline suggestions for future development. METHODS Four areas of interests were selected: indications for sphincter replacement, continence scoring and quality of life, choice of therapy, and dissemination of new technology. A questionnaire regarding these issues was developed and circulated to working party members; its results served as the basis for this consensus document. RESULTS Both electrically stimulated skeletal muscle neosphincter and artificial anal sphincter are options for patients with end-stage fecal incontinence. Electrically stimulated skeletal muscle neosphincter is also appropriate for reconstruction after surgical excision of the anorectum in selected cases. Avoidance of complications requires strict attention to sterile technique, prophylactic antibiotics, and deep venous thrombus prophylaxis. A standardized scoring system is proposed that evaluates both continence and evacuation. Quality of life is a critical endpoint for assessing sphincter replacement, and use of The American Society of Colon and Rectal Surgeons incontinence-specific quality-of-life instrument is recommended. As the efficacy of sphincter replacement becomes proven, dissemination of the technique should occur in a controlled manner to ensure adequate surgeon training, minimization of complications, and optimization of results. CONCLUSIONS Sphincter replacement by electrically stimulated skeletal muscle neosphincter and artificial anal sphincter provide a continent option for patients with end-stage fecal incontinence and those requiring abdominoperineal resection. The guidelines offered in this document are intended to facilitate the controlled and safe development and acceptance of these new techniques.

Abstract
PURPOSE Anal sphincter injury is a serious complication of childbirth, which may result in persistent anal incontinence. Occult injuries, visualized with endoanal ultrasonography, have previously been reported in up to 35 percent of females in a British study. The aim of the present study was to study anal sphincter morphology and function before and after delivery in primiparous females in the United States. METHODS Thirty-eight primiparous patients (mean age, 31 years) were evaluated with endoanal ultrasonography, anal manometry, and pudendal nerve terminal motor latency during pregnancy and after delivery. Bowel function before and after delivery was recorded according to set questionnaires. Cesarean section was performed in three patients. RESULTS Clinical sphincter tears, requiring primary repair, occurred in 15 percent of the patients. After delivery endoanal ultrasonography revealed disruptions in the external anal sphincter in six patients, but no patient had disruption in the internal anal sphincter. One patient had slight scarring in the external sphincter. Of the seven patients with pathologic findings at endoanal ultrasonography, the left pudendal latency increased after delivery (P < 0.05), and manometric results were reduced. Three of these seven patients had a third-degree or fourth-degree tear during delivery. All investigations were normal in the three patients who underwent cesarean section. CONCLUSIONS The present study demonstrates a significant frequency of sphincter injuries (20 percent) after vaginal delivery. Obstetricians should be aware of this risk and explicitly inquire about incontinence symptoms at follow-up after delivery.

Abstract
OBJECTIVE We use a loop ileostomy for temporary fecal diversion because of ease of technical construction and assumed low complication rate. Here, we review our complications of loop ileostomy and takedown using three techniques of closure. METHODS We reviewed charts of all patients who had temporary ileostomies constructed during 1987 to 1995 (n = 366). Ileostomy takedown was performed in 339 patients using one of three closure techniques: enterotomy suture (65%), resection with handsewn anastomosis (20%), and stapled anastomosis (15%). Complications were recorded for pre-takedown and 30-day post-takedown intervals. RESULTS Overall complication rate was 28%. Pre-takedown complications occurred in 21 patients (5.7%), including small bowel obstruction (2.5%) and dehydration/electrolyte derangement (2.2%). Post-takedown complications occurred in 83 patients (24.5%), including wound infection (14.2%), small bowel obstruction (5%), anastomotic leak (2.9%), and 1 death from a cardiac event. Post-takedown obstruction was higher for closure using resection with sutured anastomosis (12%) compared with enterotomy suture (2.3%), P < or = 0.003. Stapled anastomosis had an intermediate rate of obstruction (7.7%). Anastomotic leak was similar between closure techniques. CONCLUSIONS Loop ileostomy and takedown are associated with low rates of serious complications (5% or less). As such, we continue to advocate use of loop ileostomy as a diversion procedure. Closure by enterotomy suture is preferred over resection. However, if resection is required, closure by stapled anastomosis is preferred over suture anastomosis.

Abstract
BACKGROUND Cancers of the anal canal are a rare and diverse group of tumors of the gastrointestinal tract currently managed most often with surgery, chemoradiotherapy, or both. Previous investigations of cancer of the anal canal have reported on small numbers of patients, included only squamous histology, or included a select group of patients. The current study reviewed a large consecutive series of patients with cancer of the anal canal, including all histologies, who received chemoradiotherapy as the primary treatment modality. METHODS The spectrum of pathology, treatment, and outcomes for 192 patients with malignant tumors of the anal canal over a 10-year period, from 1984 to 1994, was analyzed. Patient charts were reviewed for diagnosis, staging, treatment, survival, and recurrence rates. RESULTS The pathologies of 192 patients (mean age, 58 years; 119 females and 73 males) included 143 (74%) with squamous cell carcinoma, 36 (19%) with adenocarcinoma, and 7 (4%) with melanoma. The remaining 6 patients (3%) were diagnosed with neuroendocrine tumors (2), carcinoid tumor (1), Kaposi sarcoma (1), leiomyosarcoma (1), or lymphoma (1). T classification distributions were T1 (3%), T2 (46%), T3 (28%), and T4 (12%). The overall crude 5-year survival and recurrence rates were 53% and 34%, respectively. Five-year survival rates were 57% for squamous cell carcinoma, 63% for adenocarcinoma, and 33% for melanoma. Five-year survival rates by T classification were T1 (62%), T2 (57%), T3 (45%), and T4 (17%). Twenty-one (15%) of the patients with squamous cell carcinoma underwent surgical therapy only, with a 5-year survival rate of 60% and a recurrence rate of 23% at 5 years. The remaining 122 patients (85%) with squamous cell carcinoma received chemoradiotherapy only, with a 5-year survival rate of 55% and a recurrence rate of 34% at 5 years. Salvage abdominal perineal resection for recurrent or persistent squamous cell carcinoma after chemoradiotherapy was performed on 13 patients, with 8 (62%) of them alive at a mean follow-up of 32 months. Twenty-two patients (61%) with adenocarcinoma of the anal canal were treated with surgery, and 14 patients (39%) underwent surgery with adjuvant chemoradiation therapy. The 5-year survival and recurrence rates were 63% and 21%, respectively. CONCLUSIONS Chemoradiotherapy for patients with squamous cell carcinoma offers survival rates equivalent to surgical therapy and preserved sphincter function. Adenocarcinoma managed with surgery, with adjuvant therapy for selected patients, gives good results. Melanoma continues to be associated with a poor prognosis.

Abstract
UNLABELLED Optional treatment for complete rectal prolapse remains controversial. PURPOSE We reviewed our experience over a 19-year period to assess trends in choice of operation, recurrence rates, and functional results. METHODS We identified 372 patients who underwent surgery for complete rectal prolapse between 1976 and 1994. Charts were reviewed and follow-up (median, 64: range, 12-231 months) was obtained by mailed questionnaire (149 patients; 40 percent) and telephone interview (35 patients; 9 percent). Functional results were obtained from 184 responders (49 percent). RESULTS Median age of patients was 64 (11-100) years, and females outnumbered males by nine to one. One-hundred and eighty-eight patients (51 percent) were lost to follow-up; 183 patients (49 percent) underwent perineal rectosigmoidectomy, and 161 patients (43 percent) underwent abdominal rectopexy with bowel resection. The percentage of patients who underwent perineal rectosigmoidectomy increased from 22 percent in the first five years of the study to 79 percent in the most recent five years. Patients undergoing perineal rectosigmoidectomy were more likely to have associated medical problems as compared with patients undergoing abdominal rectopexy (61 vs. 30 percent, P = 0.00001). There was no significant difference in morbidity, with 14 percent for perineal rectosigmoidectomy vs. 20 percent for abdominal rectopexy. Abdominal procedures were associated with a longer length of stay as compared with perineal rectosigmoidectomy (8 vs. 5 days, P = 0.001). Perineal procedures, however, had a higher recurrence rate (16 vs. 5 percent, P = 0.002). Functional improvement was not significantly different, and most patients were satisfied with treatment and outcome. CONCLUSIONS We conclude that abdominal rectopexy with bowel resection is associated with low recurrence rates. Perineal rectosigmoidectomy provides lower morbidity and shorter length of stay, but recurrence rates are much higher. Despite this, perineal rectosigmoidectomy has appeal as a lesser procedure for elderly patients or those patients in the high surgical risk category. For younger patients, the benefits of perineal rectosigmoidectomy being a lesser procedure must be weighed against a higher recurrence rate.Patient satisfaction]

Abstract
BACKGROUND & AIMS Dynamic muscle plasty has been advocated as therapy for refractory fecal incontinence and for anorectal reconstruction to avoid colostomy after abdominoperineal resection. This study evaluates the results of a multicenter experience with dynamic muscle plasty in the treatment of fecal incontinence and total anal reconstruction. METHODS One hundred thirty-nine patients were enrolled at 12 centers between June 1992 and November 1994 and followed up through June 1996. Intramuscular leads and neurostimulators were implanted to stimulate transposed gracilis or gluteus muscle. Success was defined as 70% reduction in solid stool incontinence for patients with baseline incontinence and zero incontinence to solid stool for patients with baseline stomas and for patients undergoing total anal reconstruction. RESULTS Overall, 85 of 128 graciloplasty patients (66%) achieved and maintained a successful outcome over the follow-up period. By etiology, these proportions were 71%, 50%, and 66% for patients with acquired fecal incontinence, congenital incontinence, and total anal reconstruction, respectively. One third of graciloplasty patients experienced a major wound complication, with therapy failing in 41%. Experienced centers had better outcomes and lower complication rates than inexperienced centers. Of the 11 gluteoplasty patients, 5 (45%) achieved and maintained a successful outcome. CONCLUSIONS Dynamic graciloplasty may be an effective procedure for patients with refractory, end-stage fecal incontinence as well as for patients who require anorectal excision for low-lying malignancy. However, the procedure has significant morbidity that can lead to functional failure. Outcome after dynamic graciloplasty appears to correlate with surgical experience. In contrast to graciloplasty, the use of dynamic gluteoplasty should be limited to investigational purposes.

Abstract
PURPOSE Because of the increased risk of colorectal cancer in patients with inflammatory bowel disease, surveillance colonoscopy with mucosal biopsies for dysplasia has been advocated to prevent malignancy or permit its early diagnosis. However, despite adoption of colonoscopic surveillance programs by many clinicians, we have noted a pattern of continued referrals for inflammatory bowel disease-associated malignancy. This study was undertaken in an effort to characterize this cohort of patients. METHODS We reviewed the operative records of a large metropolitan colorectal practice from 1983 to 1995. During this period 40 large-bowel resections were performed for patients with documented inflammatory bowel disease and concomitant carcinoma. A retrospective analysis was conducted with emphasis on clinical presentation, pathologic description, and most recent follow-up. RESULTS Mean age at the time of diagnosis of cancer was 48 years with an average inflammatory bowel disease duration of 19 years. Seven patients had documented inflammatory bowel disease for less than eight years before their cancer diagnosis. Carcinomas were identified preoperatively by colonoscopy in 92 percent of patients. One-half of these patients had the colonoscopy to investigate a recent change in inflammatory bowel disease symptoms or signs, whereas the other half underwent endoscopy as routine surveillance. For the remaining 8 percent of patients, operated on for worsening symptoms, the carcinoma was detected in the pathological specimen only. The majority of patients (68 percent) did not have a preoperative diagnosis of dysplasia. Twenty-five percent of tumors were mucinous, 20 percent were multicentric, and 70 percent were located distal to the splenic flexure. Among the seven patients who died, four had pancolitis, six had a recent worsening of symptoms, and all had cancer involving the rectum. CONCLUSION Cancer occurs at a younger age in patients with long-standing inflammatory bowel disease. The tumors are often mucinous, multiple, and located in the left colon. Despite increasing acceptance of surveillance colonoscopy as a recommended strategy in cancer prevention, almost one-half of the patients in this study had their cancer diagnosed because increased colitis symptoms led to colonoscopic examination. Eighteen percent of patients developed cancer with less than an eight-year history of inflammatory bowel disease. These data call into question the effectiveness of dysplasia surveillance as a population-based strategy to decrease the colorectal cancer mortality in inflammatory bowel disease patients.

Abstract
BACKGROUND Management of left-sided colonic obstruction is a surgical challenge. This study was performed to review our management of patients with left colon obstruction presenting to the University of Minnesota Hospitals over a 10-year period, 1985 to 1994. STUDY DESIGN We did a retrospective chart review of 143 patients (48 male and 95 female; mean age 70 years). RESULTS Sites of obstruction were rectosigmoid, 40%; sigmoid colon, 47%; descending colon, 5%; and splenic flexure, 8%. Fifty-two percent of patients had obstructing colorectal cancer. Two patients presented with generalized peritonitis secondary to colonic perforation. The majority (n = 121, 85%) of patients underwent resection (subtotal in 39 [32%], and segmental in 82 [68%]) and anastomosis in a single stage after appropriate resuscitation. Intraoperative colonic cleansing was undertaken in 40 patients (28%). Morbidity within 30 days of operation was 11%, including 1 anastomotic leak, and mortality was 3%. The 4 deaths occurred in patients over 75 years of age and were not from anastomotic complications. CONCLUSIONS A single stage resection and an anastomosis facilitated by intraoperative colonic cleansing in one-third of cases was performed in 85% of patients presenting with left colon obstruction. One anastomotic leak occurred. Our current policy of strongly favoring a single stage, definitive operation for patients presenting with left colon obstruction appears reasonable on the basis of this retrospective review of our experience.

Abstract
PURPOSE Treatment of severe constipation caused by combined colonic inertia and nonrelaxing pelvic floor is controversial. This study is designed to evaluate the outcome of preoperative biofeedback and subtotal colectomy for patients with combined colonic inertia and nonrelaxing pelvic floor. METHODS One hundred six patients who underwent subtotal colectomy for intractable constipation from 1982 through 1995 answered a detailed questionnaire regarding postoperative bowel function, symptoms of abdominal pain and bloating, and degree of satisfaction after the operation. Sixteen of these patients had a combination of colonic inertia and nonrelaxing pelvic floor diagnosed by transit marker study, electromyography, and defecography. These patients completed preoperative biofeedback training. RESULTS Electromyographic relaxation of pelvic floor musculature was demonstrated after the biofeedback treatment in all patients, but symptoms of difficult evacuation persisted. Postoperatively, seven patients (43 percent) had complete resolution of symptoms of constipation or difficult evacuation. Six patients still complained of incomplete evacuation that was severe in two and unresponsive to postoperative biofeedback. Three patients (18 percent) complained of diarrhea (>5 bowel movements per day) and incontinence of liquid stools (at least one episode a week). Nine patients (56 percent) were satisfied despite persistent symptoms. CONCLUSIONS Subtotal colectomy can improve some symptoms in patients with slow transit constipation and nonrelaxing pelvic floor. However, incomplete evacuation persists in a significant number of patients and almost one-half of patients are dissatisfied with their surgery.

Abstract
PURPOSE Traumatic sphincter disruption frequently is associated with a rectovaginal fistula, but the effect of a persistent sphincter defect on the outcome of rectovaginal fistula repair is poorly documented. We analyzed the outcome of rectovaginal fistula repairs based on preoperative sphincter status. PATIENTS AND METHODS We identified 52 women who underwent 62 repairs of simple obstetrical rectovaginal fistulas between 1992 and 1995. Fourteen patients (27 percent) had preoperative endoanal ultrasound studies and 25 (48 percent) had anal manometry studies. Follow-up was by mailed questionnaire in 36 patients (69 percent) and by telephone interview in 12 (23 percent), for a total response rate of 92 percent. Median age was 30.5 (range, 18-70) years, and median follow-up was 15 (range, 0.5-123) months. Twenty-five patients (48 percent) complained of varying degrees of fecal incontinence before surgery. There were 27 endorectal advancement flaps and 35 sphincteroplasties (28 with and 8 without levatoroplasty). RESULTS Success rates were 41 percent with endorectal advancement flaps and 80 percent with sphincteroplasties (96 percent success with and 33 percent without levatoroplasty; P = 0.0001). Endorectal advancement flap was successful in 50 percent of patients with normal sphincter function but in only 33 percent of patients with abnormal sphincter function (P = not significant). For sphincteroplasties, success rates were 73 vs. 84 percent for normal and abnormal sphincter function, respectively (P = not significant). Results were better after sphincteroplasties vs. endorectal advancement flaps in patients with sphincter defects identified by endoanal ultrasound (88 vs. 33 percent; P = not significant) and by manometry (86 vs. 33 percent; P = not significant). Poor results correlated with prior surgery in patients undergoing endorectal advancement flaps (45 percent vs. 25 percent; P = not significant) but not sphincteroplasties (80 vs. 75 percent; P = not significant). CONCLUSIONS All patients with rectovaginal fistula should undergo preoperative evaluation for occult sphincter defects by endoanal ultrasound or anal manometry or both procedures. Local tissues are inadequate for endorectal advancement flap repairs in patients with sphincter defects and a history of previous repairs. Patients with clinical or anatomic sphincter defects should be treated by sphincteroplasty with levatoroplasty.

Abstract
Conservative surgical techniques are an alternative to radical surgery for selected patients with rectal carcinoma. The goals of conservative management are to select patients with low risk for nodal metastases and achieve local tumor control while preserving anal sphincter function. Patient selection is critical to achieve this outcome because properly selected patients can obtain results comparable to radical surgery. Selection is based on preoperative histologic characteristics and endorectal ultrasonography. Predictors of pelvic lymph node metastasis risk include tumor grade, depth of penetration, mucinous features, and vascular and lymphatic invasion. Endorectal ultrasound (ERUS) is important in accurately staging the lesion by identifying both depth of invasion and presumptive nodal status. The options for local therapy reviewed include techniques of full-thickness local excision and ablative procedures including endocavitary irradiation, electrocoagulation, and laser therapy. The techniques of full-thickness transanal excision and endocavitary irradiation are described with results from the University of Minnesota experience.

Abstract
UNLABELLED Endoanal ultrasonography has become an important tool in the evaluation of patients with anal incontinence. However, the extent of anterior defects is sometimes difficult to quantitate during endoanal ultrasonography. PURPOSE This study was designed to evaluate perineal body measurement during endoanal ultrasonography in assessing patients with obstetric anal sphincter injuries. METHODS Forty-two patients with anal incontinence because of obstetric sphincter injuries and 13 asymptomatic subjects were investigated with endoanal ultrasonography. Sphincter muscle thickness, sphincter defects, and perineal body were measured. Perineal body measurement was performed by inserting a finger, held gently against the posterior vaginal wall, into the vagina and measuring the distance between the inner surface of the internal sphincter and the ultrasonographic reflection of the finger. RESULTS All patients had anterior sphincter lesions of varying extent. Mean size of internal sphincter lesions was 146 degrees, and mean size of external sphincter lesions was 107 degrees (P < 0.001). Perineal body measurement was performed without difficulty in all patients and subjects. Perineal body measurement (mean +/- standard deviation) was 6 +/- 2 mm in patients and 12 +/- 3 mm in asymptomatic subjects (P < 0.001). Ninety-three percent of patients had perineal body measurement < or = 10 mm, and 70 percent of asymptomatic subjects had perineal body measurement > 10 mm. Digital delineation of the perineal body during endoanal ultrasonography improved the visualization of sphincter lesions in 74 percent of patients. CONCLUSIONS Digital delineation of the perineal body during endoanal ultrasonography improved the visualization of sphincter lesions in the majority of patients. Perineal body measurement is performed without difficulty and is a good predictor of anterior sphincter lesions. Use of this technique improves visualization of sphincter lesions.

Abstract
PURPOSE This study was designed to evaluate the anatomic and functional consequences of lateral internal sphincterotomy in patients who developed anal incontinence and in matched controls. METHODS The study includes 13 patients with anal incontinence after lateral internal sphincterotomy and 13 controls who underwent the same operation and were continent and satisfied with the results of the procedure. Patients underwent clinical evaluation, anorectal manometry, pudendal nerve terminal motor latency testing, and endoanal ultrasonography. RESULTS Sphincterotomies were longer in incontinent patients (75 vs. 57 percent), but the resting pressure and length of the high-pressure zone were not different between groups. Surprisingly, maximum voluntary contraction was higher in incontinent patients than in continent controls (136 vs. 100 mmHg). Rectal sensation and pudendal nerve terminal motor latency were similar in both groups. The defect in the internal sphincter was wider in incontinent patients than in continent controls (17.3 vs. 14.4 mm), but these differences were not statistically significant. The thickness of the internal sphincter measured by endoanal ultrasound was identical in both groups, but the external sphincter was thinner in incontinent patients both at the site of the sphincterotomy (6.8 vs. 8.1 mm) and in the posterior midline (7.1 vs. 8.6 mm). CONCLUSIONS Anal incontinence after lateral internal sphincterotomy is directly related to the length of the sphincterotomy. Whether secondary to preoperative sphincter abnormality or the result of lateral internal sphincterotomy, the external sphincter is thinner in incontinent patients than in continent controls.

Abstract
BACKGROUND The aim of this study was to compare the clinical results obtained with the cutting seton and the two-stage seton fistulotomy (TSSF) in the surgical management of high anal fistula. METHODS The case records of 59 patients with high anal fistula of cryptoglandular origin treated with cutting seton (n = 12) or TSSF (n = 47) over a 5-year period were retrospectively reviewed. There was no difference between the groups in age, sex distribution, or estimated percentage of anal sphincter involved by the fistula. Follow-up was by a mailed questionnaire inquiring about fistula recurrence, incontinence, and degree of satisfaction. Mean follow-up was similar in both groups (27 months for cutting seton versus 33 months for TSSF). Comparisons were made by Student t and chi 2 tests, as required. RESULTS There were no differences in the rate of fistula recurrence between the groups treated with cutting seton or TSSF (one of 12 versus four of 47), difficulty holding gas (six of 12 versus 25 of 47), underwear staining (six of 12 versus 18 of 47), stool incontinence (three of 12 versus 12 of 27), overall incontinence (eight of 12 versus 31 of 47) and mean incontinence score (4.9 versus 4.2). The fistula healing time and degree of satisfaction with the operation were not significantly different between the groups. One-half of the patients treated by TSSF had the seton removed under general or epidural anaesthesia. CONCLUSION Both techniques are equally effective in eradicating the fistula, and both are associated with a similar rate of incontinence.

Abstract
PURPOSE This study was designed to assess the efficacy of computed tomography-guided percutaneous abscess drainage in intestinal disease. METHODS Retrospective chart review of patients who underwent percutaneous abscess drainage for complications of intestinal disease with or without surgery between 1990 and 1994. RESULTS Eighty-two patients with 111 abscesses were identified. Causes of abscess included anastomotic leaks (35 percent), postoperative complications without leak (30 percent), and diverticular disease (23 percent). Complete success (no surgery necessary) was achieved in 53 of 82 patients (65 percent). Nine patients (11 percent) who underwent interval surgery were classified as having partial successes. Twenty-six of 26 (100 percent) well-defined unilocular collections containing pus were successfully drained. Complex abscesses (loculated, poorly defined, multiple, associated with fistula, draining feces) were successfully drained in 35 of 55 patients (63 percent). Success rates varied inversely with the number of complicating factors present. Apache II scores of 15 or higher were associated with decreased success rates. CONCLUSION Percutaneous abscess drainage is a highly successful technique for treatment of patients with intra-abdominal infection related to intestinal disease. Although several factors are associated with decreased success rates and multiple complicating factors combine to reduce success rates, no identifiable factor or combination of factors preclude the possibility of a successful outcome.

Abstract
BACKGROUND Faecal incontinence is difficult to treat. A variety of reconstructive procedures has been described, but none is entirely satisfactory. This study evaluated the feasibility of cross-innervating a skeletal muscle neosphincter with the pudendal nerve in a canine model. METHODS Thirty dogs were rendered surgically incontinent (the pudendal nerve was cut and the external sphincter was partially excised). A neosphincter was then created using the semitendinosus muscle. In ten dogs pudendal nerve transposition (PNT) to the nerve to the semitendinosus muscle was performed. Ten dogs were given a dynamic neosphincter by inserting a pulse generator at 6 weeks. The remaining ten dogs served as controls with passive semitendinosus wraps. Anal manometry was performed before operation and monthly for 5 months. Muscle biopsies, performed at the initial operation and at 5 months, were stained for slow- and fast-twitch fibres, and were examined histologically. RESULTS At 1 month, mean sphincter function was 32 per cent of the preoperative value in the control animals, 34 per cent in the PNT group and 27 per cent in the electrostimulation group; all dogs were incontinent. At 5 months the mean recovery of sphincter function was 42 per cent of the preoperative value in controls, 100 per cent in dogs with PNT (P < 0.001) and 63 per cent in dogs having electrostimulation (stimulator on) (P = 0.02). Six dogs with PNT had squeeze pressures equal to or greater than preoperative levels. At 5 months the ratio of slow to fast fibres was significantly greater in all dogs (control P = 0.01, PNT P < 0.005, electrostimulation P < 0.001). CONCLUSION Use of the pudendal nerve to innervate a canine skeletal muscle anal wrap produced a functional anal sphincter that was superior to electrically stimulated and passive wraps.

Abstract
Risk of colorectal cancer recurrence has traditionally been determined by use of pathologic staging. However, it is apparent that subgroups of patients exist within tumor stages whose clinical behavior differs. This study was undertaken to identify tumor-associated factors that might be predictive of outcome in patients with intermediate stages who will benefit the most from postsurgical adjuvant therapy. Seventy patients with stage II and III colorectal cancer were assessed for DNA index, S-phase fraction, p53 expression, and Ki-67 index. Tumor recurrence was analyzed by means of nonparametric tests and Cox proportional hazard models incorporating standard clinical and pathologic criteria. Of the four prognostic markers evaluated, Ki-67 index was significantly associated with disease recurrence (P = 0.02), whereas DNA index, S-phase fraction, and p53 expression were not. After stratification by tumor stage, significant associations between Ki-67 index and disease recurrence were retained in stage II tumors (P = 0.01) but not in stage III tumors (P = 0.23). Cox proportional hazard regression analysis indicated that among stage II patients, those with a Ki-67 index >45% were associated with 6.5 times greater risk for disease recurrence than those with a Ki-67 index >/=45%. It was concluded that an elevated Ki- 67 index is associated with an increased risk of tumor recurrence in stage II colorectal cancer.

Abstract
PURPOSE This study was undertaken to assess results of surgery for fistula-in-ano and identify risk factors for fistula recurrence and impaired continence. METHODS We reviewed the records of 624 patients who underwent surgery for fistula-in-ano between 1988 and 1992. Follow-up was by mailed questionnaire, with 375 patients (60 percent) responding. Mean follow-up was 29 months. Fistulas were intersphincteric in 180 patients, transsphincteric in 108, suprasphincteric in 6, extrasphincteric in 6, and unclassified in 75. Procedures included fistulotomy and marsupialization (n = 300), seton placement (n = 63), endorectal advancement flap (n = 3), and other (n = 9). Factors associated with recurrence and incontinence were analyzed by univariate and multivariate regression analysis. RESULTS The fistula recurred in 31 patients (8 percent), and 45 percent complained of some degree of postoperative incontinence. Factors associated with recurrence included complex type of fistula, horseshoe extension, lack of identification or lateral location of the internal fistulous opening, previous fistula surgery, and the surgeon performing the procedure. Incontinence was associated with female sex, high anal fistula, type of surgery, and previous fistula surgery. CONCLUSIONS Surgical treatment of fistula-in-ano is associated with a significant risk of recurrence and a high risk of impaired continence. Degree of risk varies with identifiable factors.

Abstract
OBJECTIVE To critique changing trends in the surgical management of diverticular disease. DESIGN Case series. Two hundred twenty-seven consecutive patients required surgery for diverticular disease from 1988 to 1993. Patient records were reviewed retrospectively. Operative procedures included primary resection in all patients with either anastomosis, anastomosis with proximal ileostomy, or the Hartmann procedure. Morbidity, mortality, and length of stay were then compared with each operative procedure and stage of disease. Patients were categorized according to the following pathologic stages: stage 0, no inflammation; stage I, chronic inflammation; stage II, acute inflammation with or without microabscesses; stage III, pericolonic or mesenteric abscess; stage IV, pelvic abscess; and stage V, purulent or feculent peritonitis. SETTING A university hospital and private affiliated hospitals in a large metropolitan area. MAIN OUTCOME MEASURES Study outcome parameters included mortality, morbidity, length of hospital stay, and leak rates. These outcomes were then compared with different disease stages and treatments. RESULTS Mean patient age was 66 years (range, 25-98 years). Male-female ratio was 84:143. Mean follow-up was 23 months (range, 1-132 months). There were 50 fistulas: 24 colovesical, 21 colovaginal, 3 colocolonic, 1 coloenteric, and 1 colouterine. Surgery was categorized as elective for 196 patients (86%), urgent for 12 (5%), and emergent for 19 (8%). Primary resection was performed in all cases. Primary anastomosis was performed in 200 patients (88%), 183 without and 17 with proximal diversion. Twenty-seven patients (12%) underwent a Hartmann procedure with colostomy; 19 patients (70%) have since undergone colostomy closure. Morbidity occurred in 52 patients (23%), including 4 anastomotic leaks (2%). There were 3 perioperative deaths (1%). Mean length of initial hospital stay was 11 days (range, 4-59 days). Length of stay was 5 days (range, 4-7 days) for ileostomy closure (7% morbidity) and 13 days (range, 7-35 days) for the colostomy closure after the Hartmann procedure (33% morbidity). CONCLUSIONS Primary resection is virtually always possible in complicated diverticular disease. Primary anastomosis, with or without proximal diversion, is safe for patients with no abscesses or localized abscesses and should be considered on an individual basis for patients with pelvic abscesses and peritonitis. Colostomy closure after the Hartmann procedure is associated with significant length of hospitalization and morbidity and leaves one third of patients with permanent stomas.

Abstract
PURPOSE This study was undertaken to compare the healing rate and long-term effects on continence of open and closed lateral internal sphincterotomy. METHODS Charts of 864 patients with chronic anal fissure who underwent internal sphincterotomy as a single procedure over five years by a group of 12 colorectal surgeons were reviewed. Open internal sphincterotomy (OIS) was performed in 521 patients, whereas 343 had closed internal sphincterotomy (CIS). There was no difference in sex or age between the groups. A questionnaire inquiring about clinical outcome, changes in continence, and degree of satisfaction with the procedure was mailed to all patients. A total of 549 (63.5 percent) patients, 324 (62.2 percent) with OIS and 225 (65.6 percent) with CIS, returned their questionnaires. Average follow-up was three (range, 1-6) years. RESULTS Differences in persistence of symptoms (3.4 OIS vs. 5.3 percent CIS), recurrence of the fissure (10.9 vs. 11.7 percent CIS), and need for reoperation (3.4 percent OIS vs. 4 percent CIS) were statistically not significant. However, statistically significant differences were seen in the percentage of patients with permanent postoperative difficulty controlling gas (30.3 vs. 23.6 percent; P 0.062), soiling underclothing (26.7 vs. 16.1 percent; P < 0.001), and accidental bowel movements (11.8 vs. 3.1 percent; P < 0.001) between those who underwent OIS and those who had CIS. Although 90 percent of patients reported general overall satisfaction, more patients undergoing CIS (64.4 percent) than OIS (49.7 percent) were very satisfied with the results of the procedure. CONCLUSIONS Lateral internal sphincterotomy is highly effective in treatment of chronic anal fissure but is associated with significant permanent alterations in continence. CIS is preferable to OIS because it effects a similar rate of cure with less impairment of control.

Abstract
BACKGROUND Preoperative adjuvant radiation combined with chemotherapy is a recent development in the management of patients with rectal cancer invading perirectal tissue and regional lymph nodes. This study was performed to assess the impact of preoperative adjuvant therapy in patients judged by endorectal ultrasound to have extramural invasion of rectal cancer and/or regional lymph node involvement on tumor regression in bowel wall and lymph nodes. The predictive value of ultrasound in staging wall penetration and lymph node involvement after preoperative adjuvant therapy was also assessed. METHODS Patients (n = 43) were selected by ultrasound to have preoperative irradiation (4,500-5,040 cGy over 5-6 weeks). In 30 patients this was combined with 5-fluorouracil, 370 mg/m(2), for 5 days in the first and last weeks of irradiation. Pretreatment ultrasound was compared with pathologic findings in the resected specimen in all patients. Twenty-one were assessed by ultrasound after adjuvant therapy and findings compared with histology. RESULTS Downstaging was seen in 23 (53%) patients with wall invasion and in 23 (72%) of 32 patients with lymph node involvement. Overall, downstaging was achieved in 30 (70%). Positive predictive values of ultrasound after irradiation were 72% and 56% for wall penetration and lymph node status, respectively. Negative predictive values of ultrasound after irradiation were 100% and 82%, respectively. CONCLUSION In the majority of patients with rectal cancer invading perirectal tissues or lymph nodes, lesions may be downstaged by preoperative adjuvant therapy. Endorectal ultrasound after adjuvant therapy for rectal cancer is of a lesser predictive value chiefly because of overstaging.

Abstract
PURPOSE This study was undertaken to review the literature regarding the current therapy for recurrent and extensive anal warts. METHODS The available treatments for condyloma acuminatum are reviewed with particular regard to their efficacy for recurrent or extensive anal lesions. Topical agents, surgical methods, and the use of interferon are discussed. Treatment of anal warts in the immunocompromised patient is also addressed. CONCLUSIONS Although small lesions may be responsive to repeated applications of topical agents, more extensive lesions require surgical or combination treatment. Intralesional interferon may be a useful adjunct to surgical methods to decrease recurrence.
