The Laparoscopic Management of Benign Bowel Fistulas

BACKGROUND: The presence of a fistula has usually been a factor predicting high conversion and complication rates following laparoscopic procedures for Crohn's disease and diverticulitis. METHODS: We studied retrospective data collected from the medical case notes of patients. A single surgeon carried out all these procedures from 1991 through 2001. RESULTS: Fourteen patients underwent 15 procedures. Six patients were males and 8 were females. The diagnosis was Crohn's disease in 10 patients and diverticulitis in 4. In 10 cases, the operation was the primary procedure, but 5 procedures were for recurrences. Two patients with diverticulitis and 3 with Crohn's disease had only the fistulae divided with the application of an Endo-GIA stapler across the fistulae (stapled fistulectomy). No bowel resections were carried out in these 5 patients. Four cases had to be converted due to bleeding (23%). The only postoperative complication was a single case of wound infection after conversion. CONCLUSION: The presence of a fistula isn't necessarily an indication for conversion. If it is possible to dissect the loops free, we believe that a stapled fistulectomy is effective with a low incidence of fistula recurrence, especially in Crohn's disease.
