Introduction: Colovesical fistula (CVF) is a condition with various aetiologies and presentations. Surgical treatment is necessary in most cases. Due to its complexity, open approach is preferred. However, laparoscopic approach is reported in the management of CVF due to diverticular disease. The aim of this study was to analyse the management and outcome of patients with CVF of different aetiologies treated with laparoscopic approach.
Patients and methods: This was a retrospective study. We retrospectively reviewed all patients undergoing elective laparoscopic management of CVF from March 2015 to December 2019.
Statistical analysis used: None.
Results: Nine patients underwent laparoscopic management of CVF. There were no intraoperative complications or conversions to open surgery. A sigmoidectomy was performed in eight cases. In one patient, a fistulectomy with sigmoid and bladder defect closure was performed. In two cases of locally advanced colorectal cancer with bladder invasion, a multi-stage procedure with temporary colostomy was chosen. In three cases, with no intraoperative leakage, we did not perform bladder suture. Four Clavien I-II complications were recorded. Two fragile patients died in the post-operative period. No patients required re-operation. At a median follow-up of 21 months (interquartile range: 6-47), none of the patients had recurrence of fistula.
Conclusions: CVF can be managed with laparoscopic approach by skilled laparoscopic surgeons in different clinical scenarios. Bladder suture is not necessary if leakage is absent. Informed counselling to the patient must be guaranteed concerning the risk of major complications and mortality in case of CVF due to malignant disease.
