BACKGROUND: Patients with extensive hepatic alveolar echinococcosis might require ex vivo liver resection and autotransplantation to remove the lesion. Patients with extensive vascular invasion will need reconstruction, but the selection of the proper graft is complicated. This study aimed to investigate the effectiveness and adverse events of using the ligamentum teres hepatis as a vascular replacement graft in ex vivo liver resection and autotransplantation.
METHODS: This was a retrospective case series of patients with hepatic alveolar echinococcosis who underwent ex vivo liver resection and autotransplantation between August 2010 and October 2018 and in whom the ligamentum teres hepatis was used to repair the remnant liver. The operative outcomes, recurrence, and survival were examined.
RESULTS: Twenty-four patients were included (10 men, 14 women). The anhepatic period was 290 to 672 minutes (median of 450 minutes). The ratio of the remnant liver volume to the standard liver volume was 0.43 to 0.97 (median of 0.71). The blood loss was 1,000 (500-5,000) mL. The postoperative hospital stay was 23 (1-85) days. Of the 24 patients, 3 died after the operation, but those deaths were unrelated to liver vascular complications.
CONCLUSION: The ligamentum teres hepatis could be used as a vascular replacement graft in ex vivo liver resection and autotransplantation. It has the advantages of convenient specimen extraction, no donor site injury, and no immunological rejection, which has promising clinical application prospects.
