Repeat colonoscopy after endoscopic polypectomy.

The records of all patients undergoing endoscopic polypectomy between December 1979 and December 1982 were reviewed. One hundred seventy-two patients underwent colonoscopic polypectomy in the absence of carcinoma or inflammatory bowel disease. Of these, the polyp could not be retrieved in 4, and 19 were lost to follow-up. One hundred forty-nine patients underwent subsequent endoscopy from one to four years after the initial polypectomy. Seventy-five (50.3 percent) of the patients developed new polyps. Although 61 of the 75 patients with new polyps were identified in the first two years, new polyps were noted throughout all four years. The presence of multiple polyps on the initial examination was statistically significant in predicting new polyps. The age and sex of the patients, size of the polyps, and the presence of atypia did not identify patients at higher risk for new polyps. The data indicate that new polyps are more likely to develop in patients who had a previous polyp. It would appear that annual examinations should be performed until two successive examinations are negative. Following a second negative examination, reexamination at two- or three-year intervals, unless symptomatic, would appear to be adequate.

Factors affecting recurrence following resection for Crohn's disease.

The records of 187 patients with Crohn's disease who underwent resectional surgery were analyzed to evaluate the effect of several clinical and histologic features on the recurrence rate. Recurrence was defined as the need for re-resection. The data were analyzed by the life-table method. Age, sex, age at onset of disease and at time of resection, family history, presence of granuloma, and microscopic involvement at the line of resection did not affect the recurrence rate. The distribution of the disease and duration of symptoms before primary resection did influence the rate of re-resection. Patients with predominantly large bowel disease (N = 56) were found to have a higher rate of re-resection (45 percent) when compared with 32 percent in patients with small bowel involvement (N = 94) and with 35 percent in patients with both small and large bowel involvement (N = 37) (P = 0.04). A detailed review, an analysis of the literature, and a comparison with our results are made.

Transverse colon volvulus: a case report.

Transverse colon volvulus is a rarely encountered disorder that is difficult to diagnose preoperatively. The anatomic, physiological, and mechanical factors that predispose patients to this problem are discussed as well as various therapies. The radiographic appearance is also reviewed.

Ileorectal anastomosis for inflammatory disease of the colon.

We have reported long-term results in the cases of 42 patients following total colectomy and ileorectal anastomosis for inflammatory bowel disease. In this group, 35 patients had Crohn's disease and seven had ulcerative colitis. Five of those seven patients with ulcerative colitis had carcinoma of the colon at the time of colectomy. A diverting loop ileostomy was constructed in 14 of the 35 patients who had Crohn's colitis at the time of operation, and none of these patients had any anastomotic leakage either before or after the ileostomy was closed. However, there patients with Crohn's colitis in whom anastomotic leaks developed postoperatively; all three patients died. In the group with ulcerative colitis, one patient had an anastomotic leak but there was no operative nortality. Of the 29 patients with Crohn's disease followed for one to 18 years, 12 (41 per cent) developed recurrences in the ileum and/or rectum, and seven of these patients had to have their anastomoses taken down.

The surgical management of toxic dilatation of the colon: a report of 28 cases and review of the literature.

Experience with 28 patients with toxic dilatation of the colon is reviewed. The operative mortality in this series was 32% (9/28). Eight of the 9 patients who died were found to have colonic perforations at operation; in contrast, the group of patients with no perforations had a mortality rate of only 6%. Colonic perforation and sepsis were the most significant factors contributing to mortality and morbidity in this series. A review of the literature showed an overall operative mortality rate of 19.5% for patients with toxic megacolon; the mortality rate was 41% for patients with perforations and 8.8% for patients without perforations. It appears that the keystone to successful management is the avoidance of colonic perforation and sepsis; protracted medical management of toxic megacolon seems to have been at least partly responsible for these complications. Sixteen of the 18 survivors following subtotal colectomy required removal of the rectum within 9 months because of continued symptoms and disease in the rectal stump.
