Laparoscopic cholecystectomy after transcatheter arterial embolisation for haemobilia due to a pseudoaneurysm in the gallbladder: A case report

Abstract

Pseudoaneurysms of the cystic artery are a rare but significant complication of acute cholecystitis. Laparoscopic cholecystectomy may be a safe alternative to open cholecystectomy in such cases. We report the case of a female patient in her seventies, who presented with anaemia, jaundice, and hepatic dysfunction during hospitalisation for right knee pyogenic arthritis. The patient had no pain in the right upper quadrant. Her serum haemoglobin level was 6.5 g/dL, and upper gastrointestinal endoscopy revealed no abnormalities. Six days later, jaundice worsened, and endoscopic retrograde cholangiopancreatography revealed bloody bile. An endoscopic biliary drainage tube was inserted at the discretion of the gastroenterology department. Contrast-enhanced computed tomography revealed a haematoma in the gallbladder and a pseudoaneurysm in the lateral wall of the gallbladder. On the same day, the endoscopic biliary drainage tube was replaced with an endoscopic nasobiliary drainage tube, which indicated the degree of haemorrhage and enabled lavage of the lumen in cases of obstruction. The next day, angiography revealed a pseudoaneurysm of the deep branch of the cystic artery and coil embolisation was performed at the periphery of the cystic artery. Uninterrupted laparoscopic cholecystectomy was performed. Although laparoscopic cholecystectomy is difficult when bleeding is uncontrolled, it was safely performed following haemostasis using transcatheter arterial embolisation. Laparoscopic cholecystectomy is feasible in haemodynamically stable patients with cystic artery pseudoaneurysms after transcatheter arterial embolisation.
