Three-Part Question:
In [colovesical fistula] is [conservative management better than surgical management]in [terms of future morbidity and mortality]?
Clinical Scenario:
A 71 year old pleasant man presented to the Emergency Department complaining of dark urine, urgency, occasional dysuria, suprapubic pain and foul-smelling urine for 1 month. No frequency, haematuria or flank pain was reported. He has a past medical history of diverticulitis with lower gastro-intestinal bleeding in the past. You wonder whether all cases of colovesical fistula have to be managed surgically.

Diagnosis and Surgical Management of Colovesical Fistulas Due to Sigmoid Diverticulitis. Sebastian Melchior, Dragan Cudovic,Jon Jones, Christian Thomas, Rolf Gillitzer, Joachim Thüroff 2009 USA 49 patients who underwent surgery for colovesical fistula due to sigmoid diverticulitis Observational Morbidity Mortality & Recurrence Postoperative morbidity was 8.2% (4 of 49) and mortality was 0%. During a median followup of 68 months there were no recurrent fistulas. No conservative Management

Management of colovesical fistula P. N. Rao, R. Knox, R. J. Barnard, P. F. Schofield 1987 UK Review of 24 patients treated for colovesical fistula Retrospective Morbidity and mortality No postoperative death Morbidity (5/23) – 1 PE, 1 Recurrence, 3 wound infection No conservative Management
Conservative treatment of selected patients with colovesical fistula due to diverticulitis Amin M, Nallinger R, Polk HC Jr 1984 UK Thirty patients with colovesical fistula due to diverticulitis in the past ten years Retrospective Mortality and morbidity Six patients did not receive any of the standard operative therapies. Four of these patients were observed for three to 14 years with nonoperative management, with little inconvenience and without significant complications. Five of the 24 patients in the surgical group died in the postoperative period Small conservative management group
Author Commentary:
Only 2 studies directly answered the question. The evidence is variable with small sample data but points to the conclusion that in selected patients (benign cause), conservative Management should be offered as an option as there is no significant difference in disease-specific mortality in patients with benign colovesical fistula undergoing surgical intervention and patients treated conservatively.
Bottom Line:
Colovesical fistula occur due to various causes (Diverticulitis, colon cancer, crohn's among others). If of benign etiology, option of conservative Management should be offered to the patient when possible.
Level of Evidence:
Level 2: Studies considered were neither 1 or 3
