We present a case of acute liver failure secondary to portal vein, hepatic artery, and common bile duct injury during laparoscopic cholecystectomy, requiring a same-day emergency living donor liver transplantation (LDLT). A 57-year-old man underwent elective laparoscopic cholecystectomy at an external facility. During the operation, uncontrolled bleeding from the liver hilum led to conversion to open surgery. Despite attempts to control the bleeding with sutures, the patient developed abnormal liver enzymes postoperatively. A computed tomography scan revealed necrosis of the right liver lobe and hypoplasia of the left lobe, leading to the patient to be transferred to our center. Upon admission, the patient was found to have encephalopathy, coagulopathy, hypotension, and oliguria, with elevated transaminase levels. Based on these findings, an emergency LT was deemed necessary. Due to the unavailability of a cadaveric organ, the patient's daughter was prepared as a living donor. Exploratory laparotomy revealed a necrotic right liver lobe, atrophic left lobe, transection of the right hepatic artery and common bile duct, and a thrombosed right portal vein. The patient successfully underwent LDLT from his daughter within 24 hours. At the seventh-month follow-up, he had no complications. Hepatic vascular injury during laparoscopic cholecystectomy can lead to ALF, which carries a high mortality risk. In such cases, LDLT may be a life-saving strategy. Early referral of a patient with ALF to a transplant center is life-saving.</p>","PeriodicalId":94258,"journal":{"name":"Transplantation proceedings","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143694977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
