title: Colonic gallstones: a case report.
abstract: BACKGROUND
  Colonic gallstone is an uncommon entity with high morbidity and mortality due to various reasons. It remains a diagnostic challenge because of delayed and non-specific presentations, especially in the elderly population, often with multiple co-morbidities.
  
  
  METHODS
  We present a case of 81-year-old woman who had a large bowel obstruction due to colonic gallstone.
  
  
  RESULTS
  Immediately after a cholecysto-colonic fistula was found by laporotomy, she underwent a single stage enterolithotomy, cholecystectomy and fistula closure.
  
  
  CONCLUSIONS
  A single stage enterolithotomy, cholecystectomy and fistula closure is ideal for this condition. Various other surgical options in the literature are discussed.
