Laparoscopic central hepatectomy using a parenchymal-first approach: how we do it.

Background: Laparoscopic central hepatectomy (LCH) is a difficult and challenging procedure. This study aimed to describe our experience with LCH using a parenchymal-first approach.

Methods: Between July 2017 and June 2021, 19 consecutive patients underwent LCH using a parenchymal-first approach at our institution. Herein, the details of this procedural strategy are described, and the demographic and clinical data of the included patients were retrospectively analyzed.

Results: There were 1 female and 18 male patients, all with hepatocellular carcinoma without major vascular invasion. The mean age was 57 ± 10 years. No patients underwent conversion to open surgery, and no blood transfusions were needed intraoperatively. The average operative duration and the average Pringle maneuver duration were 223 ± 65 min and 58 ± 11 min. respectively. The median blood loss was 200 ml (range: 100-800 ml). Postoperative morbidities occurred in 3 patients (15.8%), including 2 cases of bile leakage and 1 case of acquired pulmonary infection; there were no postoperative complications happened such as bleeding, hepatic failure, or mortality. The average postoperative hospital stay was 10 ± 3 days.

Conclusion: The optimized procedure of LCH using a parenchymal-first approach is not only feasible but also expected to provide an advantage in laparoscopic anatomical hepatectomy.
