Rives-Stoppa procedure for repair of large incisional hernias: experience with 57 patients.

BACKGROUND: The use of prosthetic materials in tension-free incisional hernia repairs has diminished reherniation rates markedly; however, infection, intestinal fistulization, and seroma formation have been reported after repairs. Use of the Rives-Stoppa procedure for incisional hernia repair, in which the prosthesis is placed between the rectus abdominis muscle and the posterior sheath, may reduce occurrence of these problems. METHODS AND MATERIALS: Over a 6-year period 57 open abdominal wall incisional hernia repairs were performed using the Rives-Stoppa technique; 15 (26.3%) had previously undergone incisional hernia repair. The prosthetic materials used were polypropylene, expanded polytetrafluoroethylene (ePTFE), and ePTFE with perforations. The prosthesis size ranged from 8x8 cm to 20x28 cm (mean area 199.6 cm(2)). Follow-up consisted of an office visit 12 months postoperatively and at least one subsequent office visit or telephone interview; mean follow-up time was 34.9 months (range 11.7-81.9). RESULTS: There were no hernia recurrences (except in one patient whose prosthesis was removed), gastrointestinal complications, fistulas, or deaths. Seromas occurred postoperatively in seven patients (12.3%). Two patients (3.5%) had wound infections that required removal of the prosthesis. CONCLUSIONS: In this series the Rives-Stoppa technique had excellent long-term results, with minimal morbidity, in patients with large primary or recurrent incisional hernias. The absence of serious complications and hernia recurrences in patients with grafts in place suggests that the Rives-Stoppa procedure is the repair of choice in such patients.

Dysplasia complicating chronic ulcerative colitis: is immediate colectomy warranted?

PURPOSE: Inflammatory bowel disease surveillance strategies are designed to identify patients at greater than average risk for the development of invasive colonic carcinoma. Colonoscopic detection of mucosal dysplasia is considered the best available surveillance tool. However, the usefulness of dysplasia as a marker for cancer is uncertain. Furthermore, when dysplasia is found some suggest immediate colectomy, whereas others opt for continued surveillance. The aim of this study is to determine whether an association between dysplasia grade and cancer exists in patients with chronic ulcerative colitis, to ascertain the sensitivity, specificity, and positive predictive value of dysplasia as a cancer marker, and to clarify what action to take once dysplasia is discovered. METHODS: The pathology reports of 590 patients who underwent total proctocolectomy or restorative proctocolectomy for chronic ulcerative colitis were reviewed for dysplasia, grade of dysplasia, presence of carcinoma, and tumor stage. One hundred sixty of these patients had undergone colonoscopic examination within the year before surgery. Findings from these studies were also reviewed. RESULTS: Seventy-seven specimens (13.1 percent) contained at least one focus of dysplasia. Invasive cancers were found in 38 specimens (6.4 percent). Cancers were significantly more common among specimens with dysplastic changes (33/77 vs. 5/513; P < 0.001). Specimens with dysplasia of any grade were 36 times more likely to harbor invasive carcinoma. Stage III disease was found in association with indefinite or low-grade dysplasia in 5 of 26 (19.2 percent) of cases. Tumor stage did not correlate with dysplasia grade. Preoperative colonoscopy identified neoplastic changes in 57 (69.5 percent) cases. Dysplasia, cancer or both were missed in 25 cases. Lesions were correctly identified in only 31 (39.7 percent) of cases. Colonoscopically diagnosed dysplasia as a marker for synchronous cancer had a sensitivity of 81 percent and a specificity of 79 percent. The positive predictive value of a finding of preoperative dysplasia of any grade was 50 percent. The positive predictive value of a finding of low-grade dysplasia was 70 percent. CONCLUSIONS: Dysplasia is an unreliable marker for the detection of synchronous carcinoma. However, when dysplasia of any grade is discovered at colonoscopy, the probability of a coexistent carcinoma is relatively high. Colonoscopic evidence of low-grade dysplasia has a higher positive predictive value than either dysplasia associated mass or lesion or high-grade dysplasia. Dysplasia grade does not predict tumor stage. Because advanced cancer can be found in association with dysplastic changes of any grade, confirmed dysplasia of any grade is an indication for colectomy.

Is Hartmann's procedure safe in Crohn's disease? Report of three cases.

INTRODUCTION: Crohn's disease-associated colorectal cancer may occur in an area of defunctioning bowel. Some patients with Crohn's colitis undergo subtotal colectomy, ileostomy, and low Hartmann's procedure in an effort to preserve the rectum. This procedure has also been advocated for patients with severe anorectal Crohn's disease, in whom nonhealing of the perineal wound after proctectomy occurs with alarming frequency. The authors present a review of the literature and three cases of cancer developing in the defunctioning rectal stump despite surveillance proctoscopy. METHODS: Twenty-five patients underwent low Hartmann's procedure for severe anorectal Crohn's disease. Surveillance proctoscopy was performed as follow-up. Development of cancer in the rectal remnant or anus or recurrence of symptoms was managed by resection and adjuvant therapy. RESULTS: One patient developed squamous-cell carcinoma of the anal canal, underwent resection and adjuvant therapy, and was disease free at the time of this study. Two patients developed adenocarcinoma of the rectum. Both underwent resection and adjuvant therapy. One patient died and the other developed a recurrence. CONCLUSIONS: The authors recommend interval perineal proctectomy in all patients undergoing low Hartmann's procedure for severe anorectal Crohn's disease in whom rectal preservation is not possible. Regularly scheduled interim surveillance proctoscopy performed every two years, with biopsies of macroscopically normal-appearing and abnormal-appearing rectal mucosa and curetting of fistulous tracts, is also recommended to decrease the possibility of missing occult malignancies.

Restorative proctocolectomy in patients older than fifty years.

PURPOSE: This study was undertaken to compare functional results, complications, preoperative durations of disease, and rates of dysplasia and neoplasia between older and younger chronic ulcerative colitis patients undergoing restorative proctocolectomy (RPC) with mucosectomy. METHODS: A total of 392 patients with a preoperative diagnosis of chronic ulcerative colitis underwent elective RPC with mucosection and handsewn ileoanal anastomosis. Pathologic reports were reviewed, with specific reference to findings of dysplasia or cancer. Functional results concerning the number of bowel movements per 24 hour period and the incidence of fecal soilage were obtained by direct or telephone patient interview. FINDINGS: Group I consisted of 326 patients aged 5 to 49 (mean, 30.9) years and 160 women. Group II comprised 66 patients aged 50 to 74 (mean, 56.9) years and 29 women. Duration of disease was significantly longer in the older group (6.2 vs. 15.6 years; P < 0.001). The older group had significantly higher rates of dysplasia (29/326 vs. 19/66; P < 0.0001) and malignancy (14/326 vs. 9/66; P = 0.003). Rates of complication, hospital days following RPC, and total hospital days for all causes were comparable between groups. Perfect day-time continence was observed in 81.6 percent of Group I and 80 percent of Group II patients (213/261 vs. 40/50; P = 0.79). Perfect continence during sleep was observed in 65.1 percent of Group I and 62 percent of Group II patients (170/261 vs. 31/50; P = 0.67). Mean number of bowel movements per 24 hour period for Group I was 6.3 +/- 0.2 and for Group II was 7.4 +/- 0.5. Mean difference, one movement per 24 hours, was not significant (95 percent confidence interval, -0.02 to 2.1; t = 1.95, P = 0.055). CONCLUSIONS: We conclude that patients older than 50 years are suitable candidates for RPC with mucosectomy. Functional results and complication rates are similar to those observed among younger patients. Patients older than 50 years have a significantly higher rate of concurrent dysplasia and malignant degeneration than younger patients, most probably because of a longer duration of disease. RPC with mucosal excision potentially lowers this risk by elimination of all colorectal mucosa.

Laparoscopic-assisted intestinal resection for Crohn's disease. Which patients are good candidates?

This study was undertaken to determine preoperative criteria indicating which patients with Crohn's disease are most amenable to minimally invasive intestinal resection. Laparoscopic-assisted intestinal resection was attempted in 25 patients with Crohn's disease. Preoperative assessment of all patients included physical examination and contrast radiography. Laparoscopic intestinal resection was successfully completed in 19 patients. Four patients in whom both palpable mass and fistulous disease were present required conversion to open surgery. One patient found during surgery to have a fistula required conversion, as did one patient who had undergone previous ileocolic resection. In patients treated laparoscopically, oral alimentation, discontinuation of parenteral narcotics, and hospital discharge were possible at an average of 3.4, 4.2, and 6.5 days postsurgery, respectively. Patients operated upon using open techniques stayed in the hospital an average of 8.5 days. Laparoscopic-assisted intestinal resection is beneficial to selected patients with Crohn's disease. The presence of both a fixed mass and fistula on preoperative evaluation is predictive of conversion to open laparotomy and should be considered a relative contraindication. Patients with either a fixed mass or a fistula alone are more amenable to laparoscopic-assisted intestinal resection, while patients with primary uncomplicated Crohn's disease appear to be ideally suited to minimally invasive surgery.

Laparoscopic-assisted intestinal resection for Crohn's disease.

PURPOSE: The inflammatory process associated with Crohn's disease often makes dissection difficult, even in "open" surgery. This study was undertaken to determine if dissection and resection could be performed laparoscopically and whether it would benefit this group of patients. METHODS: Between November 1992 and November 1994, laparoscopic-assisted intestinal resection was attempted in 18 patients with Crohn's disease and was successfully completed in 14. One patient had ileal disease, requiring ileal resection with ileoileal anastomosis. The remainder had disease requiring ileocolic resections. Muscle-splitting incisions averaging 5 cm in length were made to facilitate removal of specimens. RESULTS: Commencement of oral alimentation was possible at an average of 3.6 (range, 1-7) days postoperatively. Discharge occurred at an average of 6.6 (range, 4-9) postoperative days. In comparison, 14 patients operated on by the authors for the same disease in the open manner during the past six months stayed an average of 8.5 (range, 5-14) postoperative days. Postoperative complications were minimal. CONCLUSIONS: On the basis of this initial study, it appears that laparoscopic-assisted intestinal resection can be readily performed in patients with Crohn's disease. In our early experience, we have found that laparoscopic mobilization and resection may be difficult or impossible in patients with large fixed masses, multiple complex fistulas, or recurrent Crohn's disease. Extraction incisions are frequently so large in these patients that they do not derive the same benefits from laparoscopic surgery that are enjoyed by patients without these findings. Most patients having laparoscopic resections eat earlier, may require fewer narcotics, and are able to be discharged from the hospital an average of two days earlier than patients operated on in an open manner. In addition, it appears that laparoscopic-assisted intestinal resection results in a shorter, easier convalescence and an earlier return to full activity.

Restorative proctocolectomy without diverting ileostomy.

PURPOSE: Restorative proctocolectomy (RPC) by abdominal colectomy and ileal pouch-anal anastomosis (IPAA) in the setting of chronic ulcerative colitis (CUC) and familial adenomatous polyposis (FAP) has gained widespread popularity among surgeons and patients. Traditionally, temporary loop ileostomy has been established proximal to the ileal pouch in an effort to mitigate the effects of any suture line complications that may occur. This study compares functional results and complications encountered after RPC with mucosectomy with and without temporary ileostomy. METHODS: One hundred forty-three consecutive patients with either CUC or FAP underwent RPC including mucosectomy and ileal "J" reservoir. Proximal loop ileostomy was performed in 69 patients, and ileostomy was omitted in 74. Ileostomy was omitted if the patient was taking no immunosuppressives and less than 20 mg of prednisone daily in the month preceding surgery, the anastomosis was absolutely tension-free, and blood supply to the pouch was excellent. RESULTS: There were no perioperative deaths. There were two instances of pelvic abscess, one in the diverted group and one in the nondiverted group. Occurrence of IPAA suture line dehiscence was not significantly different between the two groups (ileostomy, 4/69 (6 percent), vs. no ileostomy, 6/74 (8 percent); P > 0.05). Comparison of 129 patients with colitis with and without diversion also failed to demonstrate a significant difference with regard to IPAA suture line dehiscence (ileostomy, 4/69 (6 percent) vs. 4/60 (7 percent); P > 0.05). Frequency of bowel movements and continence were the same in both groups and were comparable with results obtained without mucosectomy. Mean hospital stay at time of RPC for the nondiverted group was significantly longer (12 days vs. 10 days; P = 0.0004). Significantly fewer patients without an ileostomy were hospitalized for partial intestinal obstruction (ileostomy, 13/69 (19 percent), vs. no ileostomy, 3/74 (4 percent); P = 0.02), and significantly fewer required enterolysis (ileostomy, 7/69 (10 percent), vs. no ileostomy, 1/74 (1 percent); P = 0.04). On average, patients without an ileostomy spent significantly fewer total days in the hospital (17 vs. 24; P = 0.002). CONCLUSION: Restorative proctocolectomy with mucosectomy and without ileostomy is the procedure of choice for selected patients with FAP and CUC. Septic complications and functional results are similar to those seen in patients managed with a stoma. Anastomotic leakage, when it occurs, can be safely managed in most cases without surgery. RPC without ileostomy results in significantly fewer episodes of intestinal obstruction, fewer instances of re-exploration, and fewer total days in the hospital.

Subtotal colectomy with Hartmann's pouch for inflammatory bowel disease.

PURPOSE: Fulminant or unremitting colitis caused by inflammatory bowel disease (IBD) is effectively managed by subtotal colectomy (STC) and standard ileostomy. However, controversy exists regarding the optimal management of the retained rectum. We reviewed our experience with intraperitoneal Hartmann's closure to determine whether this is an acceptable way to handle the rectal remnant. METHODS: We retrospectively reviewed hospital and office records of 114 consecutive patients with IBD colitis who underwent STC with Hartmann's pouch since 1988. Patient demographic data, operative details, and postoperative complications were recorded. In patients who underwent subsequent surgery, technical difficulty and complications related to rectal dissection were documented. RESULTS: There were three instances of pelvic sepsis secondary to leakage from the Hartmann's pouch, an overall incidence of 2.6 percent. Two of these patients required exploratory surgery. The third patient responded dramatically to antibiotics and transanal catheter decompression of the Hartmann's pouch. Subsequent to this experience, patients undergoing STC and Hartmann's closure for IBD colitis had transanal catheter drainage of the rectal remnant as a routine part of their postoperative care. There were no instances of leakage among the 41 patients who underwent rectal decompression. There were two reports (3 percent) of technical difficulty in locating or mobilizing the intraperitoneal rectal remnant at 60 subsequent surgical procedures. CONCLUSION: Intraperitoneal Hartmann's closure of the rectum is the preferred management in patients with intractable IBD colitis requiring STC.

Treatment of benign anal disease with topical nitroglycerin.

PURPOSE: Fissure-in-ano and acutely thrombosed external hemorrhoids are common, benign anal conditions, usually characterized by severe anal pain. Internal anal sphincter hypertonia appears to play a role in the etiology of this pain. Nitric oxide has recently been identified as the "novel biologic messenger" that mediates the anorectal inhibitory reflex in humans. This report documents a therapeutic role for nitroglycerin, a nitric oxide donor, in the treatment of acutely thrombosed external hemorrhoids and anal fissure. METHODS: Five patients with thrombosed external hemorrhoids and fifteen patients with anal fissure or ulcer were identified. A treatment regimen that included 0.5 percent nitroglycerin ointment applied topically to the anus was instituted. After one week of therapy, all patients were re-examined and questioned regarding pain relief and side effects of treatment. Fissure patients were followed for eight weeks or until healing occurred. RESULTS: All patients reported dramatic relief of anal pain following application of nitroglycerin. Pain relief lasted from two to six hours. Complete healing of fissures occurred within two weeks in ten patients and within one month in two patients. One patient, whose fissure had not healed completely within two weeks requested surgical sphincterotomy. Two patients remained with persistent anal ulcers despite two months of therapy. Both, however, were pain-free. Side effects were limited to transient headache in 7 of 20 patients. CONCLUSION: Topically applied nitroglycerin ointment appears to have a therapeutic role in the treatment of thrombosed external hemorrhoids and anal fissure.

Laparoscopic cholecystectomy: an initial report.

Sixty consecutive patients underwent an elective attempt at laparoscopic cholecystectomy between March 15 and July 31, 1990 at the Mount Sinai Hospital in New York. Fifty-two patients had successful completion of the laparoscopic cholecystectomy (87%). The reasons for conversion to open cholecystectomy were acute cholecystitis (four patients), inability to define the cystic duct-common duct junction (three patients), and one patient with an unexpected choledochal cyst variant. Forty patients (77%) were discharged on the first post-operative day, and the remaining 12 patients on the second post-operative day. Thirty-three patients (63%) required only oral pain medication, and 11 patients (21%) needed no pain medication post-operatively. Fifty-one patients (98%) had resumed normal activities by the seventh post-operative day. Cholecystectomy remains the treatment of choice for biliary colic. Laparoscopic cholecystectomy minimizes length of stay in the hospital, lessens post-operative pain, allows quicker return to normal activities, and has a superior cosmetic result.
