THE TECHNOLOGY OF LAPAROSCOPIC DONOR EXPLANTATION OF LEFT LATERAL LIVER SEGMENT FOR TANSPLANTATION

Abstract

Objective. To evaluate technical and morphological aspects of laparoscopic left lateral liver segment explantation for transplantation. Material and Methods. In Privolzhsky Federal Medical Center of FMBA of Russia 3 series (14 interventions) of laparoscopic left lateral liver sector resection were performed. Operations were performed in compliance with the principles of donor liver resection. In each series different variants of tools and hardware systems were applied. Indications were benign neoplasms of II-III segments including focal nodular hyperplasia in 12 cases and hemangioma in 2 cases. Severity of liver parenchyma damage was assessed in excised specimen. Results. Postoperative complications were not observed, patients were discharged in terms from 3 to 6 days. The average hospital stay was 3.8 days. Morphological study of histological preparations of liver tissue revealed different severity of cholestasis and steatohepatosis, fibrosis, mixed inflammatory infiltration (lymphocytes, polymorphonuclear leukocytes). Identified changes were chronic. Signs of acute ischemic damage of liver parenhima were not found. Conclusion. Laparoscopic liver resection (left lateral sector) for subsequent transplantation is technically feasible with the accumulation of experience of laparoscopic procedures.
