Long-term follow-up of patients with continent ileostomies

Thirty-six patients were evaluated after having continent ileostomies for 16 to 20 years. Follow-up included clinical examination, response to a questionnaire, blood tests, and radiologic studies of the gallbladder. In addition, reservoir biopsies from 15 patients were examined. The patients were in excellent general health, all but one having gained weight postoperatively. There was no increased risk for gallstone formation or for urinary tract stone development. Although 11 of the 36 patients had reservoirs that were not provided with a valve, 92 percent of all patients were continent. Working capacity was normal in most patients and no harmful effects of the reservoir were revealed by morphologic or biochemical studies. In conclusion, no deleterious long-term effects were found as a result of the continent ileostomy.
