Core Tip

Core Tip: Cholecystoenteric fistula, an abnormal communication from gallbladder to the gastrointestinal tract, is a rare complication of cholelithiasis. It is a type of internal biliary fistula that occurs secondary to cholelithiasis in more than 90% of cases. The clinical presentation of cholecystoenteric fistula is variable, and a preoperative diagnosis is achieved rarely, while gastrointestinal bleeding as its initial presentation is also rare. Here, we report a case of cholecystoduodenal fistula that presented with hypovolemic shock due to massive upper gastrointestinal bleeding.
