Abstract: Liver transplantation is the only effective way to save the lives of patients with end‑stage liver disease and acute liver failure, but the shortage of donor liver limits the clinical application of liver transplantation. There is few report on living donor liver transplantation using the otherwise discarded partial liver after laparoscopic hepatectomy for benign liver tumor, and there are no corresponding standards and specifications for donor selection, surgical indications, preoperative evaluation, surgical planning, operation process and technical points. Based on the clinical practice of laparoscopic hepatectomy, and combined with relevant literature, the author discusses the feasibility and problems of using the otherwise discarded partial liver after laparoscopic hepatectomy for living donor liver transplantation.
