title: Colovesical fistula--is a surgical approach always justified?
abstract: OBJECTIVE
  There is a tendency to over investigate patients with colovesical fistula and to advise surgical intervention as the sole course of action. Most patients are elderly and operative intervention often carries a high morbidity and mortality.
  
  
  METHODS
  A retrospective study of 50 patients diagnosed with a colovesical fistula over a 12-year period was undertaken at our institution. The notes of all these patients were reviewed using a standardized proforma to look at the referral pattern, symtomatology, investigation, treatment and outcomes.
  
  
  RESULTS
  Data analysis showed the median age of these patients to be 70 years with 92% having either pneumaturia or faecaluria or both as a symptom. There was no significant difference in disease-specific mortality in patients with benign colovesical fistula undergoing surgical intervention and patients treated conservatively. There was not a single documented case of septicaemia despite untreated colovesical fistula being present for a cumulative total of 3254 weeks. There was no statistically significant decline in the renal function due to the disease.
  
  
  CONCLUSIONS
  We suggest that fewer investigations be performed for the diagnosis of colovesical fistula and conservative management offered to patients with benign pathology.
