Biliary injury with bile leak is a well-recognized complication following cholecystectomy. This results in an accumulation of bile within the peritoneal cavity and may manifest with biliary ascites and peritonitis or as a localized collection called biloma. Bilomas are usually intrahepatic or are located in a subhepatic or subphrenic location with the less sac being a rare location for biloma. We present a rare case of a large biloma located in the less sac compressing the stomach. The patient was successfully managed endoscopically by the placement of multiple transmural plastic stents after cannulating and dilating the transmural tract of its impending rupture into the stomach.
