A 51-year-old male with abdominal pain underwent endoscopic retrograde cholangiopancreatography (ERCP) for clinical suspicion of a common bile duct stone or bile leak one week status post-cholecystectomy.
Bile Leak at Ducts of Luschka
The duct of Luschka is a small accessory bile duct in the right hepatic lobe which is located very close to the gallbladder bed and drains into the right or common hepatic duct. The duct reaches the gallbladder adventitial layer but does not enter the gallbladder lumen. The prevalence of this anatomic variation is estimated at one-third of the population. Injury to the duct of Luschka during laparoscopic cholecystectomy is extremely rare. One study reported two cases of bile leakage due to duct injury in a series of 1351 laparoscopic cholecystectomies. Symptoms generally appear between the 5th and 8th postoperative days and include abdominal pain with fever, local or general sepsis, or more mild nonspecific symptoms.
The least invasive treatment option is endoscopic insertion of a biliary stent, theoretically releasing pressure on the duct allowing it to close and percutaneous drainage of a biloma if present. In the setting of an acute abdomen, exploratory laparotomy with lavage of the peritoneal cavity and closure of the duct of Luschka is performed.
