Cystic Duct Remnant–Duodenal Fistula following Laparoscopic Cholecystectomy: A Case Report and Literature Review

Abstract

Laparoscopic cholecystectomy is the most common procedure performed for the management of symptomatic gallstone disease. This, however, can be complicated by the formation of fistulous communications between the biliary tree and the gastrointestinal tract. This abnormal communication allows for the flow of bile and bowel contents between two systems (biliary system and intestine), which can cause abdominal pain, nausea, vomiting, and biliary sepsis. We would like to present a rare case of fistulous communication between the cystic duct stump and duodenum and outline possible contributing factors. The literature review describes the most common interventions for the management of fistulas with emphasis on ERCP and stent preferences to eliminate transpapillary pressure gradient, which directly contributes to fistula closure.
