Background: Hepatic resection is uncommon after liver transplantation (LT), but can be a graft-saving procedure in selected cases. Herein we describe the criteria, outcome, and timing of this procedure in our series.
Methods: Between January 1996 and December 2002, 397 LTs were performed in 367 recipients, of whom 12 patients (3.2%) subsequently underwent liver graft resections because of ischemic-type biliary lesions (ITBLs) (n = 5, 41.6%), segmental hepatic artery thrombosis (S-HAT)(n = 3, 25%), recurrent hepatocellular carcinoma (HCC) (n = 2, 16.6%), liver abscess (n = 1, 8.3%), or liver trauma (n = 1, 8.3%). The patients were divided into group 1 (n = 3 all with S-HAT) who underwent early resections (within 3 months of LT), and group 2 (n = 9) who underwent late resections (after 3 months). The outcomes and postoperative mortality ratio (within 30 days) were compared.
Results: The resections consisted of four left lobectomies, three right hepatectomies, two extended right hepatectomies, one segmentectomy, one anterior trisegmentectomy, and one right lateral sectoriectomy. The perioperative mortality rate was 66.6% in group 1 (one case of myocardial infarction and one of sepsis), and 22% in group 2 (one case of sepsis and one of hepatic failure).
Conclusions: Late resections in stable patients with damage confined to the graft yield good prognosis. Even major resections are feasible graft-saving procedures. In contrast, early hepatic resections in S-HAT are associated with a worse outcome. Retransplantation should be considered the first-choice option. Sepsis significantly affects the postsurgical course.
