One hundred twenty-six patients underwent 130 end colostomies, 44 for benign and 86 for malignant disease, and were followed for an average of 35 months. The left or sigmoid colon was used in 99 and the transverse colon in 31. Stomas were made electively in 98 patients and urgently in 32. Seventy-six stomas were brought out through the incision and 54 from separate sites. There were 69 complications in 55 patients (44 percent) including 11 strictures, 9 wound infections, 14 hernias, 9 small-bowel obstructions, 4 prolapses, 2 abscesses, 1 peristomal fistula, 17 skin erosions, and 2 poor stoma locations. Fifteen complications required reoperation. Five of these procedures included stoma revision. Total numbers of complications were not related to the stoma site, the disease process, the urgency of the procedure, or the segment of colon used. Wound infections, however, were increased in urgently made stomas. The incidence of hernia was equivalent in stomas brought out through the incision or at a separate site. Forty-one patients (30 percent) had 43 colostomies closed an average of 3.5 months after creation. Thirteen patients had 14 complications--5 wound infections, 6 hernias, 2 small-bowel obstructions, and 1 rectovaginal fistula. One patient died. Four patients required reoperation. There were no anastomotic leaks. Complications were equivalent in Hartmann closures and transverse colostomy closures. Complications were similar in stomas created for cancer and those created for diverticular disease.

We conclude that formalin therapy is a safe and effective form of treatment that can be performed in the office with minimal discomfort and no complications. It can be performed multiple times until results are achieved. Formalin therapy may be useful as a first-line treatment for chronic radiation proctitis, however, a prospective controlled trial comparing modalities is required to prove this to be true.

Extended follow-up after partial lateral internal sphincterotomy demonstrates a higher complication rate than was seen in patients being followed for shorter periods. However, the complication of impaired fecal continence only occurred in 8 percent of our patients, compared with 15 percent reported in the current literature, although using the same evaluative criteria. Patient satisfaction with the results of surgery was 98 percent. Careful patient selection, absence of preoperative continence problems, and meticulous surgical techniques are necessary to achieve this type of result.

Satisfactory prolapse repair was safely performed in 78 percent of this high-risk group. Pitfalls in performing this procedure relate primarily to associated perineal and colonic conditions. Most prominent among these conditions are weak or absent and sphincter tone, perineal descent, and previous sphincter injury. Extensive diverticular disease may prohibit effective and complete proximal mucosectomy. An inadequate mucosectomy sets the stage for early recurrence of prolapse.

Variations in the management of uncomplicated sigmoid diverticulitis are noted among colon and rectal surgeons, especially in terms of antibiotic choice, discharge instructions, and follow-up outpatient studies. The survey results are compared with the conclusions reached in The American Society of Colon and Rectal Surgeons practice parameters. Documentation of practice pattern variation may serve as an educational tool for physicians to improve their quality and cost of medical care. Consideration should be given to better publicize already existing American Society of Colon and Rectal Surgeons practice parameters for this common entity.
