Abstract

Background: Enterovesical fistula (EVF) is a abnormal connection between the intestine and the bladder. The aim of the study was to analyze whether closure of the defect in the bladder wall during surgery is always necessary.

Methods: Fifty-nine patients with benign EVF undergoing surgical treatment were enrolled. A one-stage surgical procedure was performed in all patients. After the separation of the diseased bowel segment, methylene blue was introduced. Through a catheter into the bladder. Only patients with urinary bladder leakage were sutured.

Results: The most common intestinal fistula involving the urinary bladder was colovesical fistula, observed in 53% of cases. Two-thirds of patients had diverticular disease as the underlying pathology. There was no relationship between suturing of the bladder and perioperative complications. Recurrent EVF was observed in one patient with bladder suturing and in two patients without suture.

Conclusions: These findings suggest that closure of the bladder defect is not necessary in cases where a leak is not demonstrated from the bladder intraoperatively. This study is limited by its retrospective design and small numbers and a randomized controlled trial is recommended to answer this question definitively.
