Abstract
PURPOSE The aim of this study was to assess perioperative warfarin management and complications in patients requiring colonoscopy. METHODS We retrospectively reviewed 109 cases of colonoscopies performed on 94 patients requiring anticoagulation with warfarin. Patients stopped their warfarin three days before colonoscopy. Coagulation profiles obtained just before the colonoscopy showed a median prothrombin time of 13.4 seconds with a range of 11.1 to 29.1 (normal range, 10.9-13) and a median international normalized ratio of 1.2 with a range of 0.9 to 2.6. Patients restarted warfarin the day after the examination. RESULTS During the 109 colonoscopies, 47 percent of the patients underwent either hot biopsy or snare polypectomy. One examination that included several biopsies was associated with a hemorrhagic complication (0.92 percent) requiring hospitalization and transfusion. Subset analysis of the therapeutic (biopsy and snare polypectomy) group indicated a slightly higher complication rate (1.96 percent) with a median international normalized ratio of 1.3 (range, 1-2.3) and a median prothrombin time of 13.7 (range, 11.6-25.9). CONCLUSION Patients taking warfarin for anticoagulation may safely undergo colonoscopy. The risk of hemorrhagic complications increases slightly with hot biopsy or snare procedures. Further studies are needed to refine guidelines for colonoscopy in the patient requiring anticoagulation.

Abstract
PURPOSE This study was designed to assess the medical and surgical treatment of colonoscopic perforations. METHODS A retrospective review of colonoscopic perforations from 1970 to 1999 was performed. RESULTS In 30 years, 34,620 colonoscopies resulted in 31 (0.09 percent) perforations. Eighteen (58 percent) resulted from therapeutic colonoscopies, whereas 13 (42 percent) occurred after diagnostic colonoscopies. Sixteen perforations (52 percent) were identified during the procedure, 13 (42 percent) within 24 hours, and two (6 percent) within 48 hours. Twenty patients (65 percent) underwent surgical therapy, and 11 (35 percent) were treated medically with intestinal rest and intravenous antibiotics. In the medically treated group, one patient required rehospitalization for percutaneous drainage of an intra-abdominal abscess, and one patient died after requesting no further treatment because of an underlying terminal medical condition. Three patients failed medical treatment and required surgical intervention. One underwent repair with proximal diversion, whereas the remaining two received a colorrhaphy without resection or diversion. In the surgical treatment group, nine patients received colorrhaphy without diversion, seven underwent resection with primary anastomosis, and four had resection with diversion. CONCLUSION Selected patients with colonoscopic perforation may be safely treated nonoperatively. Surgical treatment is reserved for patients with a large perforation or diffuse peritonitis.

Abstract
BACKGROUND Restorative proctocolectomy, a standard operation for ulcerative colitis and familial adenomatous polyposis has significant complications, even in experienced hands. METHODS We studied surgical outcome by retrospectively reviewing cases of restorative proctocolectomy done at Ochsner Foundation Hospital from 1982 to 1995. Demographic and clinical data from two periods (1982 to 1989 and 1989 to 1995) were compared to determine factors associated with improved outcome. RESULTS We performed 145 ileal pouch-anal procedures. In 56 patients, 104 complications occurred. The more recent group had a greater incidence of inflammatory bowel disease, steroid use, and staged operations; reduced operative times and hospital stays; more general but fewer pouch-related complications. Pouch failures were similar for both groups. CONCLUSIONS Perioperative outcome appeared to be associated with technical experience, improved perioperative care, exclusion of patients with Crohn's disease,judicious surgical reoperation for pouch complications, and use of a 3-stage procedure in malnourished patients or those with acute or toxic colitis.

Abstract
PURPOSE The aim of this study was to determine the appropriate surveillance for patients with a history of adenomatous polyps whose last colonoscopic examination was normal. METHODS This was a retrospective review of a database of 7,677 colonoscopies (1990 to 1996). In patients under colonoscopic surveillance, we reviewed cases of patients who had received three colonoscopies (an index (initial) colonoscopy positive for adenomas and 2 follow-up colonoscopies (interim and final)). The risk of adenomas and cancers at final follow-up colonoscopy was compared between patients having a normal interim colonoscopy and those with a positive interim colonoscopy. The risk at final colonoscopy was also stratified by time interval and the size and number of adenomas at the initial index colonoscopy. RESULTS Two hundred four patients undergoing surveillance for adenomas met inclusion criteria. At index colonoscopy the median polyp size was 1 cm and median frequency was three polyps. At all follow-up colonoscopies, we detected 493 adenomas and one cancer (median follow-up, 55 months). At 36 months patients with a normal interim colonoscopy (n = 91) had significantly fewer polyps than patients with a positive interim colonoscopy (n = 113; 15 vs. 40 percent; P = 0.0001). By 40 months, adenomas were detected in more than 40 percent of patients in both groups. The risk after a normal interim colonoscopy was not affected by time interval or number or size of polyps. Adenomas found subsequent to a normal interim colonoscopy were dispersed throughout the colon in 28 patients and isolated to the rectosigmoid in 6 patients. CONCLUSIONS In patients with a history of adenomas, a normal follow-up colonoscopy is associated with a statistically but not clinically significant reduction in the risk of subsequent colonic neoplasms. These patients require follow-up surveillance colonoscopy at a four-year to five-year interval.

Abstract
PURPOSE Colonoscopic surveillance is recommended for patients with adenomatous polyps. Significant cost savings would result from identification of subgroups of patients in whom less costly surveillance would suffice. This study was performed to determine the natural history of patients undergoing removal of isolated rectosigmoid adenomas and to establish whether flexible sigmoidoscopy might be adequate for follow-up. METHODS A retrospective review of a database of 7,677 colonoscopies, from 1990 to 1996, identified patients who had a minimal follow-up of two years after removal of adenomatous polyps isolated to the rectosigmoid. Polyps detected on surveillance colonoscopy were categorized as distal (< or =60 cm from anal verge), proximal (>60 cm from anal verge), and diffuse (proximal plus distal). The risk of polyp formation was determined by actuarial analysis using the Kaplan-Meier method. RESULTS Sixty-two patients undergoing surveillance for adenomas met inclusion criteria. At the index colonoscopy, 124 isolated rectosigmoid polyps were identified. The median polyp size was 1 cm and median frequency was one polyp. The median follow-up time for the entire cohort (N = 62) was 53 months. At follow-up surveillance colonoscopy, 105 additional adenomas were discovered and removed in 40 patients. No malignant polyps were detected. The pattern of polyps detected were proximal (n = 19), rectosigmoid (n = 16), and diffuse (n = 5). CONCLUSIONS The majority (65 percent) of patients with isolated rectosigmoid polyps have additional polyps on long-term surveillance, and 60 percent of patients will have these polyps located proximal to the reach of a sigmoidoscope. Therefore, flexible sigmoidoscopy is not a safe alternative for surveillance of patients with isolated rectosigmoid polyps.

Abstract
Continuous mucosal involvement from the rectum proximally is one of the hallmarks of ulcerative colitis. However, recent pathologic series report appendiceal ulcerative colitis in the presence of a histologically normal cecum, representing a "skip" lesion. The clinical significance of this finding has not been established. Eighty patients, 54 males and 26 females, average age 37.9 years (range 14 to 82 years) who underwent proctocolectomy for ulcerative colitis from January 1990 to September 1995 were examined to determine the rate of discontinuous appendiceal involvement. Excluded were 12 patients with prior appendectomy and 11 with fibrotic obliteration of the appendiceal lumen. Of the remaining 57 patients, seven (12.3%) had clear appendiceal involvement in the presence of a histologically normal cecum. These seven patients clinically were indistinguishable from the 50 patients without skip involvement of the appendix in terms of age at surgery, pretreatment medications, type of surgery, interval from diagnosis to definitive procedure, complications, functional results, and clinical course. Discontinuous appendiceal involvement was found in 12.3% of patients undergoing proctocolectomy for ulcerative colitis, and clinically these patients behave as those without this feature.

Abstract
PURPOSE This study was designed to evaluate the long-term outcome and survival of patients treated for malignant colonic polyps. METHODS A retrospective review of 15,975 cases of colonoscopies with 8,685 endoscopic polypectomies performed between 1972 and 1990 was undertaken. In 65 patients, the polypectomy specimens contained invasive carcinoma. Six patients were excluded (follow-up, <6 months). Polyp data, operative findings, and follow-up on the remaining 59 patients were recorded. RESULTS Malignant polyps were found in 35 males and 24 females who had an average age of 64 (range, 39-81) years. Follow-up ranged from 12 to 202 (mean, 90) months. Tumor differentiation was poor in one and well or moderately differentiated in 58 patients. Positive or indeterminate margins were found in 13 patients. Thirty-seven (63 percent) patients were managed with polypectomy and surveillance. Four of these (with rectal tumors) also had an additional local excision for questionable margins. One recurrence was noted in a patient who refused surgery, which was recommended because of indeterminate margins. Twenty-two patients (37 percent) underwent colectomy. Indications included Haggitt Level 3 or 4 invasion (19), inadequate margins (7), patient preference (1), and poor differentiation (1). Residual disease was found in colectomy specimens of three patients (14 percent). There were no cancer-related deaths in either treatment group. Life table analysis demonstrated a five-year survival of 82 percent for the colectomy group and 95 percent for the polypectomy group (P = 0.15). CONCLUSION Treatment of patients with malignant polyps must be individualized based on evolving criteria. Patients in whom polypectomy margins are inadequate should undergo colectomy. With appropriate selection criteria, patients selected for colectomy had a five-year survival rate similar to the rate of those treated by polypectomy alone.

Abstract
To determine the safety and cost-effectiveness of outpatient preoperative bowel preparation with polyethylene glycol-electrolyte lavage solution, we retrospectively analyzed 726 cases of colectomy done by colon and rectal surgeons between July 1987 and July 1991. Included were 319 patients who had elective segmental or total abdominal colectomy with primary anastomosis. Patients who required protective proximal stoma were excluded. Patients requiring emergency surgery, colostomy closure, and restorative proctocolectomy were excluded. Patients were separated into two groups equally matched by age, sex, procedure done, and comorbidity: 145 had bowel preparation as outpatients and 174 as inpatients. Both groups had similar numbers of days hospitalized, days receiving nothing by mouth, and days requiring nasogastric intubation or gastrostomy tube, as well as similar postoperative complications. There was one wound infection, one anastomotic leak, and one death in each group. Cost of outpatient preparation was approximately $40. Cost of inpatient preparation, including a semiprivate room, was approximately $400. Outpatient preparation with polyethylene glycol-electrolyte lavage solution and oral antibiotics before elective colon resection can be done with equivalent safety and at a substantial cost savings.

Abstract
PURPOSE This study was performed to evaluate whether the time interval from injection of technetium Tc 99m (99mTc)-labeled red blood cells to the time of a radionuclide "blush" (positive scan) can be used to improve the efficacy in predicting a positive angiogram. METHOD A retrospective review revealed 160 patients who received 99mTc-labeled red blood cell scintigraphy for evaluation of massive lower gastrointestinal hemorrhage between 1989 and 1994. Patients were included who demonstrated signs of shock on admission, had an initial decrease in hematocrit of > or = 6 percent, or required a minimum transfusion of two units of packed red blood cells. Scanning duration was 90 minutes, with imaging every 2 minutes. Time interval from injection to a positive scan was analyzed to determine predictability of a positive angiography. RESULTS Of 160 patients, 86 demonstrated positive scans, of whom 47 underwent angiography. These 47 patients were divided into two groups according to scan results. Group 1 (n = 33) had immediate appearance of blush; Group 2 (n = 14) had blush after two minutes. In Group 1, 20 of 33 patients had a positive angiogram, yielding a positive predictive value of 60 percent (P = 0.033). Of the 14 patients with negative angiograms (13 from Group 1, and 1 with a negative scan), 6 had radiographic occlusion of the inferior mesenteric artery and 1 had spasm of the right colic artery, with scans that blushed in the respective distributions. Excluding these seven patients yielded a positive predictive value of 75 percent (P = 0.0072) for angiography. In patients with a delayed blush (Group 2), 13 of 14 had negative angiograms, yielding a negative predictive value of 93 percent (92 percent excluding those with nonvisualization of the inferior mesenteric artery). Twenty of 21 (95 percent) positive angiograms occurred in Group 1 patients. Of the 27 patients with negative angiograms, 13 were Group 2 patients. CONCLUSION Patients with immediate blush on 99mTc-labeled red blood cell scintigraphy required urgent angiography. Patients with delayed blush have low angiographic yields. These data suggest that patients with delayed blush or negative scans may be observed and evaluated with colonoscopy.

Abstract
Perineal approaches to the repair of rectal prolapse are frequently used in elderly or high-risk patients. These repairs have lower operative mortality and morbidity than intra-abdominal repairs but in general have higher recurrence rates. This study reviews our recent results with perineal prolapse repairs, briefly summarizes the literature, and discusses the available perineal operations. Eight patients (mean age 75 years) underwent surgical prolapse repair over an 18-month period. Treatment was by Altemeier's procedure (perineal rectosigmoidectomy) in 6 patients and Delorme's procedure in 2 patients. There were no operative mortalities, and an anastomotic dehiscence in 1 patient was managed nonoperatively. All patients with preoperative constipation improved and no patient reported worsening of continence. Surgical approaches from the perineum may be used in elderly and poor risk patients to treat rectal prolapse with low mortality and morbidity. These techniques have not adversely affected fecal continence and have improved symptoms of constipation with an acceptable rate of recurrence.

Abstract
PURPOSE This study was undertaken to evaluate the incidence, diagnostic methods, and treatment of hemorrhage occurring after colonoscopic polypectomy. METHODS A retrospective chart review was conducted of 12,058 patients who underwent colonoscopy at an academic referral center between January 1989 and July 1993. Of these, 6,365 patients required polypectomies or biopsies. RESULTS After these procedures, 13 patients (0.2 percent) developed lower gastrointestinal hemorrhage requiring hospitalization. All bleeding episodes occurred within 12 days of polypectomy or biopsy (mean = 8 days). Twelve patients (92 percent) underwent technetium-tagged red blood cell scintigraphy, which localized bleeding in four patients (31 percent). In the eight patients with normal scintigrams, hemorrhage did not recur, and no further evaluation was performed. Five patients (38 percent) underwent arteriography. Arteriogram was positive in two of four patients with positive scintigrams, and bleeding was controlled with selective vasopressin infusion. The fifth patient had arteriography without prior diagnostic studies because of massive hemorrhage; the bleeding site was identified and controlled with selective vasopressin infusion. Three patients had lower gastrointestinal endoscopy, with endoscopic identification of bleeding site in two patients, and endoscopic electrocautery controlled the bleeding in one patient. In the 13 patients with hemorrhage, cessation of bleeding occurred with intestinal rest and hydration in nine patients (69 percent), selective vasopressin infusion in three patients (23 percent), and endoscopic electrocautery in one patient (8 percent). Eight patients (62 percent) required blood transfusion with a mean of 4.8 units (excluding one patient on warfarin sodium who required 14 units of blood). No patient required surgical intervention. CONCLUSIONS Incidence of hemorrhage after colonoscopic polypectomy or biopsy is low, and in our series, hemorrhage resolved without the need for surgical intervention. Management includes initial stabilization followed by diagnostic evaluation. Technetium-tagged red blood cell nuclear scintigraphy identifies ongoing bleeding and identifies patients in whom additional invasive procedures (arteriography lower gastrointestinal tract endoscopy) are warranted.

Abstract
PURPOSE We retrospectively reviewed the records from our past five years of experience with colostomy closure at a large multispecialty hospital to determine postoperative morbidity. RESULTS From March 1988 to April 1993, 46 patients underwent colostomy closure. Patients ranged in age from 24 to 87 (mean, 41.8) years, and 25 (54 percent) were women. Stomas had been created during emergency operations in 40 patients (87 percent); most operations (54 percent) were for complications of acute diverticulitis. Of the 46 procedures, 40 (87 percent) were end colostomies, and 6 were loop colostomies. Stomas were closed at a range of 11 to 1,357 days after creation (mean, 207 days; median, 116 days). Twenty-six patients (57 percent) underwent colostomy closure alone, and the remainder underwent additional procedures ranging from appendectomy to hepatic lobectomy. Duration of operations ranged from 1 to 9.5 (mean, 4.2) hours, and estimated blood loss averaged 400 ml. Overall hospital stay for closure was 6 to 62 (mean, 11.5) days. Inpatient complications occurred in 15 percent of patients, including congestive heart failure (2 percent), cerebrovascular accident (4 percent), pneumonia (2 percent), enterocutaneous fistula (2 percent), and pulmonary embolus with death (2 percent). The most common long-term complication was midline wound hernia, which occurred in 10 percent of surviving patients. Overall, complications occurred in 24 percent. CONCLUSIONS Colostomy closure is a major operation; however, with good surgical judgement and technique, associated morbidity and mortality can be minimized.

Abstract
PURPOSE This study was performed to determine cost-effective colonoscopy guidelines for patients with prior colorectal adenocarcinoma. METHOD A retrospective review was performed of patients who had been treated for colorectal adenocarcinoma and later underwent follow-up colonoscopy from 1984 to 1994. RESULTS During this study period, 389 patients previously treated for colorectal adenocarcinoma underwent follow-up colonoscopy. All patients had perioperative colon evaluation for other neoplasms. Ages ranged from 26 to 89 (mean, 65.8) years, and 46.8 percent were female. Recurrent or metachronous cancer or a neoplastic polyp constituted a positive examination. Results of 389 first follow-up colonoscopies were compared with 259 second (66.6 percent), 165 third (42.4 percent), and 83 fourth (21.3 percent) follow-up examinations. Median interval between all colonoscopies was 13 months. Positive examination rates for the first two yearly examinations were 18.3 and 18.5 percent, respectively. Slightly lower, third-year and fourth-year positive examination rates were 16.4 and 14.5 percent, respectively. Four-year examinations yielded the following: first year--1 carcinoid, a new adenocarcinoma, and 100 polyps; second year--1 anastomotic recurrence and 68 polyps; third year --55 polyps; and fourth year--1 recurrent cancer and 17 polyps. CONCLUSIONS These data suggest that 1) annual follow-up colonoscopy for two years after colorectal cancer surgery is beneficial for detecting recurrent and metachronous neoplasms and 2) the interval between subsequent examinations may be increased depending on the result of the most recent examination.

Abstract
PURPOSE To determine the physiologic alteration resulting in fecal seepage and soiling, results of anorectal manometric testing were evaluated in patients with varying degrees of fecal incontinence. METHODS Anal manometric studies performed on 170 patients with fecal incontinence were reviewed. Results of their studies, including mean resting pressure, maximum resting pressure, maximum squeezing pressure, minimum rectal sensory volume, and minimum volume at which reflex relaxation first occurs, were compared with those of 35 control group subjects with normal fecal continence. Manometric studies were performed using a four-channel, water-perfused catheter. Incontinent patients were divided into three groups based on presenting complaints: complete incontinence (incontinence of gas and liquid and solid stool), partial incontinence (incontinence of gas and liquid), and seepage and soiling (incontinence of small amounts of liquid and solid stool without immediate awareness). RESULTS Resting pressures were significantly lower in complete incontinence, partial incontinence, and seepage and soiling groups than in the controls (P < 0.001). Resting pressures of the complete incontinence group were also significantly lower than those of the partial incontinence and seepage and soiling groups (P = 0.03). Squeezing pressures were lower for both the complete incontinence and partial incontinence groups than for those in the control group (P < 0.001) and in the seepage and soiling group, which did not differ significantly from controls. The minimum rectal sensory volume was greater in all incontinent groups than in controls (P < 0.001). Sensory volume of the seepage and soiling group was significantly greater than that of the complete incontinence and partial incontinence groups (P < 0.01). The difference between sensory volume and the volume producing reflex relaxation was greatest in the seepage and soiling group and differed from that of the partial incontinence and control groups. CONCLUSIONS These findings suggest that the mechanism of incontinence is different in seepage and soiling patients and involves a dyssynergy of rectal sensation and anal relaxation. Patients with the pattern of seepage and soiling may be successfully treated with stool bulking agents (e.g., psyllium or bran).

Abstract
Increasing experience with colonoscopy has altered recommendations for the frequency of follow-up surveillance examinations for adenomatous polyps and colorectal cancer. Current recommendations include a follow-up colonoscopy at 1 year for patients with more than two adenomatous or highly suggestive polyps and after curative surgery for colorectal cancer. Other patients can safely receive a follow-up colonoscopy at longer intervals of 3 years. Published data and a review of the Ochsner Clinic experience are presented to support these recommendations.

Abstract
A 76-year-old female was noted to have a rectal mass on evaluation for postmenopausal bleeding. There was no history of abdominal pain, constipation, or rectal bleeding. Flexible sigmoidoscopy revealed a 3-cm pedunculated rectal mass at 10 cm. Hair fibers were visible through the smooth glistening surface. At colonoscopy, the polyp was removed by snare polypectomy. Histology showed epidermal, mesodermal, and endodermal components diagnostic of benign cystic teratoma. Subsequent total abdominal hysterectomy and bilateral salpingo-oophorectomy revealed endometrial carcinoma and postmenopausal ovaries. Primary rectal teratoma is a very rare rectal mass that may present endoscopically. Since 1865, only 33 cases have been reported in the literature. Endoscopic photographs, histology, and a review of the literature are presented.

Abstract
The significance of mucinous carcinoma has been controversial since first described by Parham in 1923. Previous reports have suggested that mucinous tumors affect young patients, involve the more proximal colon, are more advanced at diagnosis, and have a poorer prognosis than nonmucinous colon carcinoma. More recent reports have refuted these results. In an effort to clarify the significance of mucinous histology, a retrospective review of cases of invasive colon cancer treated at the Ochsner Clinic between 1982 and 1985 was undertaken. Mucinous adenocarcinoma, as defined by > or = 50 percent mucin, was found in 52 patients. During the same period, 343 nonmucinous adenocarcinomas were resected. The mean age, distribution within the colon, stage at diagnosis, and survival of mucinous carcinoma patients were compared with those with nonmucinous tumors. Mucinous tumors presented at a statistically significant more advanced stage (38 percent vs. 22 percent Dukes C lesions; P < 0.01). No significant differences were seen in age at presentation, distribution within the colon, or stage-for-stage survival when the entire group was analyzed. Mucinous carcinomas of the rectum occurred at an advanced stage more frequently (P < 0.05) than nonmucinous rectal carcinomas and had a markedly worse five-year survival (11 percent vs. 57 percent; P < 0.002).

Abstract
Forty-eight cases of Ogilvie's syndrome, colonic pseudo-obstruction, presenting between 1983 and 1989 were retrospectively reviewed to assess the results of colonoscopic decompression and to identify potential etiologic factors. Three patients had spontaneous resolution with medical treatment. Forty-five patients required 60 colonoscopic decompressions: 38 (84 percent) were successfully treated using colonoscopy; five (11 percent) required an operation; and two died within 48 hours of colonoscopy from medical causes. No complications or deaths were the result of colonoscopy. Twenty-nine patients (64 percent) were successfully treated with a single colonoscopy. One-third of patients required serial decompressions. Average cecal diameter in patients with successful colonoscopic decompression was 12.4 cm but was larger for patients requiring more than one colonoscopy (13.3 cm) and for those who failed colonoscopic therapy (13.4 cm). The spine or retroperitoneum had been traumatized or manipulated in 52 percent of patients. Patients with Ogilvie's syndrome were being treated with narcotics (56 percent), H-2 blockers (52 percent), phenothiazines (42 percent), calcium-channel blockers (27 percent), steroids (23 percent), tricyclic antidepressants (15 percent), and epidural analgesics (6 percent) at diagnosis. Electrolyte abnormalities included hypocalcemia (63 percent), hyponatremia (38 percent), hypokalemia (29 percent), hypomagnesemia (21 percent), and hypophosphatemia (19 percent). Colonoscopic decompression in Ogilvie's syndrome is safe and effective management. Multiple pharmacologic and metabolic factors, as well as spinal and retroperitoneal trauma, appear to alter autonomic regulation of colonic function, resulting in colonic pseudo-obstruction.

Abstract
One hundred seventy patients with gastrointestinal carcinoid tumors were treated at Ochsner Clinic from 1958 to 1990. Ninety-four rectal carcinoid tumors were diagnosed and treated during this time. Carcinoid tumors of the rectum represented the most frequent primary site (55 percent), followed by carcinoids of the ileum (12 percent), appendix (12 percent), colon (6 percent), stomach (6 percent), jejunum (2 percent), pancreas (2 percent), and other (5 percent). One-half of rectal carcinoids were discovered during anorectal examination of asymptomatic patients. The remainder were found primarily by examination of patients for symptoms of benign anorectal conditions. The diagnosis of rectal carcinoid was made at the time of initial examination in 61 patients. This allowed definitive treatment in a single session by local excision and fulguration in 48 patients. The remainder were treated by repeat biopsy and fulguration (25 patients) or by transanal excision (12 patients). Overall, 85 carcinoid tumors of the rectum measuring less than 2 cm were treated by local excision and fulguration or by transanal excision, with an average five-year follow-up. There were no local recurrences. Ten patients with metastasizing rectal carcinoids averaging 4 cm were treated. All were symptomatic at presentation and fared poorly despite radical surgery. Three were alive at three years but only one survived five years. At our institution, rectal carcinoids were the most frequently detected carcinoid tumor. Small carcinoids of the rectum were adequately treated by local excision and fulguration or by transanal excision, with no local recurrence. The true incidence of rectal carcinoids is detected only with careful and complete rectal examination of the asymptomatic screening population by experienced surgeons. With more widespread screening of the well population, rectal carcinoids may become recognized as the most frequent human carcinoid tumor.

Abstract
A prospective study investigated the significance of solitary diminutive colonic polyps discovered during screening flexible sigmoidoscopy. Eighty-two patients with a solitary diminutive polyp (less than or equal to 5 mm) underwent colonoscopy after cold biopsy of the index polyp. Of the patients with adenomatous index polyps, 42.5 percent had proximal neoplastic polyps. Of the patients with hyperplastic index polyps, proximal neoplastic polyps were found in 38.9 percent. These data suggest that diminutive polyps identified during flexible sigmoidoscopy, whether adenomatous or hyperplastic, place the patient in the intermediate risk group for colorectal neoplasia. We recommend that any patient with polyps seen during screening sigmoidoscopy, regardless of histopathology, should undergo colonoscopy.

Abstract
Seventy-three patients underwent total colectomy, rectal mucosectomy, creation of J or S ileal reservoir, and ileal pouch-anal anastomosis from 1982 to 1989. Mean follow-up was 38 months, with a minimum of 3 months in 15 patients being followed long-term at another institution. Forty-eight (66%) patients had histologically proven ulcerative colitis and 25 (34%) patients had familial polyposis. Thirty-eight J reservoirs and 35 S reservoirs were constructed. There were no perioperative deaths. The failure rate (loss of pouch) was 3%. Thirty-six complications in 34 (47%) patients were reported, 14 (19%) patients required surgery. Bowel obstruction was the most common postoperative complication (16%), followed by pouchitis (15%), and cuff infection (5%). Seventy-eight percent of the complications were associated with the J pouch. Average stool frequency at 1 year was 4 per 24-hour period. Other complications included postoperative pneumonia (1), peroneal nerve palsy (1), and temporary sexual dysfunction (1). Seven of 15 complications requiring surgical intervention occurred in the first 2 years of the study period, illustrating the learning curve associated with the procedure. Blood loss, transfusion requirements, and length of operation were not associated with higher complication rates. Use of the J pouch and experience of the individual surgeon affected morbidity.

Abstract
The records of 201 asymptomatic patients who underwent colonoscopy based solely on a family history of colon cancer were reviewed. Eighty-five patients (42 percent) had a total of 166 lesions. Fifty-four (27 percent) patients of the screened population had neoplastic lesions, while 31 (15 percent) patients had nonneoplastic polyps. Four carcinomas were found. Twenty-five of the patients with polyps (29 percent) had no polyps distal to the splenic flexure; these proximal polyps (and two carcinomas) would have been missed on screening with fiberoptic sigmoidoscopy. Nineteen of these 25 patients had polyps smaller than 0.5 cm, which likely would have been missed with contrast enemas. Almost one half (47 percent) of all polyps discovered at screening colonoscopy were proximal to the descending colon. Only one patient younger than 40 years old had adenomas. The yield of polyps and cancer in patients with familial risk indicates screening colonoscopy should be considered after age 40.

Abstract
This retrospective study defines a population with neoplastic colonic polyps who have had colonoscopic polypectomy and, in follow-up within one year, a repeat colonoscopic evaluation. The population was broken down into two groups, one group that had polyps at the second examination and one group that did not. This study determined which factor(s) were significant among this population in distinguishing whether new polyps would be found at one year follow-up. The authors found that among the many variables studied, only polyp multiplicity was significant in predicting polyp recurrence. More than one polyp found at index colonoscopy led to a significant chance of having a new polyp after only one year. Also, it was demonstrated that these "new" polyps were unlikely to have been "missed" polyps from the initial colonoscopy. Because of the shifting location, smaller size, and fewer instances of histologic atypia in these polyps compared with those at index examination, the authors believe that polyps found after one year may be assumed to have arisen de novo. Finally, the authors show that a significant number of polyps occur beyond the reach of the flexible sigmoidoscope (approximately 60 cm). The authors recommend that patients who have polyps undergo a colonoscopic examination. When patients are re-evaluated after having colonoscopic neoplastic polypectomy, they should undergo repeat colonoscopy.

Abstract
Perforation of the rectum or sigmoid colon complicated 5 of 2200 barium-enema examinations performed during a 4-year period. Three patients with rectal perforations manifested by air extravasation were successfully treated with intravenous antibiotics and complete bowel rest. Two patients with barium extravasation were treated with immediate operation and colostomy. All five patients recovered. Perforation was found to be associated with a rectal stricture due to ulcerative colitis, a rectal cancer, an incarcerated inguinal hernia, fulminant ulcerative colitis, and a normal colon in an elderly patient. To determine the pressure in the rectum that could potentially be generated during a barium-enema examination, the pressures created by a standard barium delivery set were measured, using 1-meter columns of water, 25 percent diatrizoate sodium (Hypaque), 20 percent barium, and 80 percent barium. The columns generated pressures of 70, 85, 95, and 120 mm Hg respectively. Squeezing the delivery bag increased the pressure 21 to 79 percent or a maximum of 55 mm Hg. Colorectal perforation during barium-enema examination that was not accompanied by barium extravasation could be successfully treated nonoperatively. The associated pathology and our studies of pressures generated during a barium-enema examination allow us to suggest that the incidence of colorectal perforation during barium-enema radiography can be reduced by 1) performing proctoscopy prior to barium enema, 2) avoiding the use of the rectal balloon in patients with known rectal lesions, 3) avoiding barium studies in patients with active colitis, 4) avoiding generation of pressure greater than that created by a column of barium suspension of one meter, and 5) using a lower concentration of barium when possible.

Abstract
A retrospective review of patients with Crohn's disease treated at our institution from 1973 to 1986 revealed 35 patients operated upon for anorectal fistulas. Twenty-nine had low intermuscular fistulas (multiple in seven), and six had high intermuscular (supralevator) fistulas. Fistulotomy alone was performed in 19 patients, and eight underwent partial fistulotomy and seton insertion. Five additional patients had proximal fecal diversion before fistulotomy. Three patients with severe colonic and anorectal disease underwent proctocolectomy as the initial procedure. Of the 32 patients who had fistulotomy performed, complete healing occurred in 30. Seven patients who healed required more than one operation for fistula. One patient was left with an asymptomatic fistula, and one required proctectomy for persistent symptomatic fistula and proctitis. Success of operation correlated with absence of rectal disease and quiescent disease elsewhere in the gastrointestinal tract. Aggressive medical treatment is required to control bowel disease preoperatively. In the majority of patients, subsequent surgery is justified and healing can be anticipated.

Abstract
A retrospective review of patients with Crohn's disease treated at our institution from 1973 to 1986 revealed 12 patients operated on for rectovaginal fistula. Disease involved the large intestine in 10 patients. Primary fistula repair was performed in four patients and four others had staged repair with preliminary fecal diversion. Four patients with severe colonic and anorectal disease had proctocolectomy performed as the first procedure. Of eight patients who underwent fistula repair, complete healing occurred in six. One patient has a persistent fistula, which is minimally symptomatic, and the other required proctocolectomy after three unsuccessful repairs. Success of operation correlated with quiescent intestinal disease and absence of rectal involvement. In selected patients with symptomatic fistulas, surgical repair is indicated and healing can be anticipated.

Abstract
Primary granulomatous inflammation of the appendix is a rare entity. When fungi, parasites, foreign bodies, and obstruction secondary to fecalith, mucocele, or tumor have been eliminated histologically as causes, fewer than 80 cases have been reported in the literature since 1932. Various diseases have also been suggested, including tuberculosis, sarcoidosis, Crohn's disease, and Yersinia pseudotuberculosis. A case of primary granulomatous inflammation of the appendix is presented, and 61 cases reported in the literature since 1953 are reviewed. Patients presented with pain in the right lower quadrant of the abdomen frequently associated with a mass and a protracted preoperative course. Of the 61 patients, 31 were men, 24 were women, and the sex of six of the patients was not reported. The median age of patients was 21 yr. The majority (77%) underwent simple appendectomy. Of patients undergoing ileocolectomy, five of 14 (36%) had concurrent granulomatous ileal involvement. The majority of specimens exhibited appreciable transmural thickening with fibrosis, noncaseating granulomas, formation of Langhans giant cells, and mucosal ulceration. No operative deaths and no postoperative fecal fistulas occurred. In patients without concurrent or synchronous granulomatous disease elsewhere who were followed from 1 to 16.8 yr (mean 5.2 yr), the incidence of recurrence approximated 14%. Therefore, patients with granulomatous appendicitis appear to have a favorable prognosis but require careful long-term observation.
