A Case of Asymptomatic Cholecystogastric Fistula / 대한소화기내시경학회지

ABSTRACT

Biliary enteric fistulas which are caused by gallstone, peptic ulcer and carcinoma are an uncommon disease. Their incidence appears to increase recently with the advent of endoscopy. The usual types of the fistulas are choledochoduodenal, cholecystoduodenal and cholecystocolonic. But, cholecystogastric fistulas are very rare. Their symptoms are usually nonspecific and pneumobilia has been considered as a clue, but the diagnosis is difficult in most cases. At present, endoscopy is very helpful to the diagnosis. The treatment of asymptomatic fistulas is still in dispute. Endoscopic management is being used at times in recent days. We recently experienced a case of cholecystogastric fistula accidentally. During the evaluation for the cause of anemia, we suspected a fistula on endoscopy and confirmed it on endoscopic fistulography and managed it by endoscopic papillotomy and stone extraction.
