- Abstract: Objective To investigate the safety and clinical efficacy of the Laennec membrane left side hepatic parenchymal transection-first approach combined with APR triangle in laparoscopic anatomical central hepatectomy.Methods 24 patients underwent laparoscopic anatomical central hepatectomy via Laennec membrane left side hepatic parenchymal transection-first approach combined with APR triangle from January 2023 to June 2024 were selected.Statistical analysis of patients with operation time,intraoperative blood loss,postoperative complications,and postoperative hospital stay.Results All the 24 patients underwent laparoscopic anatomical central hepatectomy without perioperative death.The operation time was(210.2±75.6)minutes(range:95～295 min),and the intraoperative blood loss was(358.9±118.4)mL(range:150～1 100 mL).There was no intraoperative blood transfusion and no conversion to open surgery.The abdominal drainage tube was removed on the average of(5.5±0.5)d(range:4～10 d)after operation,and the average postoperative hospital stay was(7.5±1.5)d(range:5～16 d).There were 5 cases of Clavien-Dindo grade Ⅰ and Ⅱ complications,including 4 cases of abdominal effusion and 1 case of pleural effusion.Postoperative pathology:all patients were hepatocellular carcinoma.Patients with liver malignant tumor were followed up for 1 month to 1.5 years.All the patients survived during the follow-up period,and 2 patients had tumor recurrence.Conclusion For central hepatic segment tumors,laparoscopic anatomical central hepatectomy can be performed using the left hepatic parenchyma via Laennec membrane priority approach combined with APR triangle method,which is safe and feasible.
