Hepatic artery pseudoaneurysm and hemobilia following laser laparoscopic cholecystectomy - A case report

This report describes injury to the hepatic artery with pseudoaneurysm formation and hemobilia following the use of laser-assisted dissection to perform laparoscopic cholecystectomy. A 57-year-old woman was referred emergently 2 weeks after laser laparoscopic cholecystectomy with upper abdominal pain, upper gastrointestinal bleeding, and jaundice. A selective hepatic arteriogram showed a right hepatic artery pseudoaneurysm which was embolized. Two weeks later the patient had recurrent hemobilia as the result of blood flow restoration in the pseudoaneurysm and a fistula to the cystic duct remnant. She was treated with two additional embolizations and direct injection of the aneurysm with thrombogenic material. Follow-up at 2 years showed no further recurrence. Since the laser has never been shown to have advantages over electrocautery, its use during laparoscopic cholecystectomy is difficult to justify.
