Enterovesical fistulas complicating Crohn's disease: clinicopathological features and management.
Enterovesical fistula is a relatively rare condition in Crohn's disease. This study was undertaken to examine clinicopathological features and management of enterovesical fistula complicating Crohn's disease. Thirty patients with enterovesical fistula complicating Crohn's disease, treated between 1970 and 1997, were reviewed. Urological symptoms were present in 22 patients; pneumaturia in 18, urinary tract infection in 7, and haematuria in 2. In 5 patients clinical symptoms were successfully managed by conservative treatment, and they required no surgical treatment for enterovesical fistula. Twenty-five patients required surgery. All the patients were treated by resection of diseased bowel and pinching off the dome of the bladder. No patients required resection of the bladder. The Foley catheter was left in situ for an average of 2 weeks after operation. Three patients developed early postoperative complications; two bowel anastomotic leaks, and one intra-abdominal abscess. All these complications were associated with sepsis and multiple fistulas at the time of laparotomy. After a median follow-up of 13 years, 3 patients having postoperative sepsis (anastomotic leak or abscess) developed a recurrent fistula from the ileocolonic anastomosis to the bladder, which required further surgery. In the other 22 patients without postoperative complications there has been no fistula recurrence. In conclusion, the majority of patients with enterovesical fistula required surgical treatment: resection of the diseased bowel and oversewing the defect in the bladder. The fistula recurrence was uncommon, but the presence of sepsis and multiple fistulas at the time of laparotomy increased the incidence of postoperative complications and fistula recurrence.
