Single-layer continuous colon and rectal anastomosis using monofilament absorbable suture (Maxon): study of 500 cases.

PURPOSE: The study purpose was to evaluate the results of continuous, single-layer colon and rectal anastomoses using a monofilament absorbable suture material (Maxon). METHODS: Four hundred ninety-two consecutive patients undergoing five hundred colon and rectal anastomoses with the above technique were evaluated for outcome, including anastomotic leakage, stricture, and other complications, by means of chart review. RESULTS: Three patients (0.6 percent) died after surgery and 7 (1.4 percent) developed clinical evidence of anastomotic leakage. Twenty-four percent developed some postoperative complications, most of which were minor. CONCLUSIONS: Continuous, single-layer colorectal anastomosis using monofilament absorbable suture can be performed safely, quickly, and with a favorable cost ratio. Handsewn anastomoses should still be part of the armamentarium of the well-trained surgeon.

Development of invasive adenocarcinoma in a long-standing Kock continent ileostomy: report of a case.

The first case of adenocarcinoma developing in a continent ileostomy is reported. A healthy, 39-year-old man with a continent ileostomy for 17 years developed subacute obstructive symptoms and was found on endoscopy to have a large adenocarcinoma involving the intussusception valve. At operation, he was found to have a large tumor originating in the valve, extending through the reservoir, and involving the afferent ileal limb. A number of metastatic lymph nodes were identified in the mesentery of the small bowel. He underwent excision of the pouch and formation of an end ileostomy. He is currently undergoing adjuvant chemotherapy. Biochemical and morphologic changes in the ileal pouch, both in the pelvis and the continent ileostomy, are discussed. The implications of this apparent de novo cancer arising in an ileal pouch are discussed.

Ambulatory surgical hemorrhoidectomy--a solution to postoperative urinary retention?

PURPOSE: The most frequent complication of surgical hemorrhoidectomy is urinary retention. This study evaluates the incidence of urinary retention in a series of patients undergoing surgical hemorrhoidectomy in an ambulatory setting. METHODS: The records of all patients undergoing anorectal surgical operative procedures during the calendar year 1990 were reviewed, with particular emphasis on urinary retention and other postoperative complications. RESULTS: Of 201 patients undergoing full surgical hemorrhoidectomy by Colon and Rectal Clinic, 91 percent had operations performed on an ambulatory basis (discharge less than four hours following surgery). Of these 190 patients, only 1 (0.53 percent) required urinary catheterization during the postoperative period. CONCLUSIONS: The ambulatory setting, when combined with careful patient education and perioperative fluid restriction, allows surgical hemorrhoidectomy to be performed with a very low incidence of urinary retention to the benefit of both patient and surgeon.

Local excision of carcinoma of the rectum for cure.

During the past 10 years, we have treated 63 patients with invasive adenocarcinoma of the rectum by full-thickness local excision. Rigid criteria were employed in patient selection. None of the tumors was pedunculated or in situ carcinoma. Of the 63 lesions, 53 were confined to the bowel wall and constitute the basis for this report. Thirty-five lesions penetrated only the submucosa and 18 invaded the muscularis propria. Twenty-four patients underwent full-dose postoperative radiotherapy with minimal complications. Follow-up ranged from 12 to 130 months, with a median of 44 months. Four tumors recurred locally (8%). Of these, two patients apparently have been salvaged by reexcision. One patient died 32 months after abdominoperineal resection of brain metastases (without local tumor). One patient who did not receive close follow-up died of local recurrence. Seven have died of unrelated causes. The 5-year corrected disease-free survival is 90%. Local excision combined with radiotherapy for selected rectal cancers yields a high rate of cure with minimal morbidity and is now our preferred mode of treatment for all patients whose tumors meet our rigid criteria.

Results of 1,000 single-layer continuous polypropylene intestinal anastomoses.

Between 1979 and 1988, we created intestinal anastomoses in 1,000 patients using a single-layer, continuous suturing technique and a polypropylene suture. The technique is easily learned, flexible in its application, and incurs less cost than most other techniques. The anastomoses involved all levels of the colon and the upper (intraperitoneal and extraperitoneal) rectum. All patients were followed for a minimum of 1 year. The clinically suspected anastomotic leak rate was 1%. Other morbidity included would complications (2%), obstruction of the small intestine (2%), anastomotic stricture (1%), and death (1%). No death was due to anastomotic complications. These rates of complications are comparable with, and in many instances lower than, those reported with other techniques of intestinal anastomosis.

Single-layer polypropylene colorectal anastomosis. Experience with 100 cases.

The technique of single-layer continuous polypropylene colorectal anastomosis is described. The authors' experience with their initial 100 cases is analyzed in detail. No clinical leaks or anastomotic strictures were noted in a two-year follow-up period. The technique is safe, easily learned, rapidly performed, and it does not add significantly to the cost of medical care. The authors' total experience with this anastomosis now exceeds 350 cases.
