Gallbladder bleeding along with cholecystocolonic fistula: a case report.

Abstract

Gallstone disease is a major public-health problem, with a high prevalence ranging from 10% to 15% [1]. Acute cholecystitis, chronic cholecystitis, choledocholithiasis, and gallstone pancreatitis are all common complications in clinical practice. However, when gallstones migrate to adjacent viscera or vascular structures, the clinical challenge is far less familiar [2]. Gallbladder (GB) bleeding is seldom reported, which mostly manifests as hemobilia. Some cases are caused by cystic artery aneurysm and rupture and others are due to GB rupture [3]. Gallstones can erode through the gallbladder wall or bile duct into the adjacent portion, resulting in a cholecystocolonic fistula (CCF), which is a rare complication of gallstones with cholecystitis [4]. Here, we share a case of gallbladder bleeding along with cholecystocolonic fistula that has not yet been reported. We hope that, through our unusual case, clinicians gain an enhanced understanding of rare complications caused by gallstones.
