Abstract
Background:
Appropriate surgical techniques for controlling bleeding and preserving residual liver function are key to the success of laparoscopic liver resection. This study aims to evaluate the application effect of intraoperative ultrasound in the Pringle maneuver of laparoscopic liver resection.
Materials and Methods:
Between January 2022 and June 2023, 100 patients underwent laparoscopic liver resection and were randomly allocated to receive application of intraoperative ultrasound for Pringle maneuver (intraoperative ultrasound group, n = 50) or conventional Pringle maneuver (conventional group, n = 50). Intraoperative blood loss, blood transfusion, operation time, hepatic portal block time, complications (bile leakage, hemorrhage, ascites, and posthepatectomy liver failure), and hospital stay were compared between groups, along with the alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin (TB) levels at postoperative days 1, 3, and 7.
Results:
The operation time, postoperative ALT, AST, and TB levels on postoperative days 1, 3, and 7, complications (bile leakage, hemorrhage, ascites, and posthepatectomy liver failures), and hospital stay were comparable between groups. Compared with the conventional group, the intraoperative ultrasound group had significantly less intraoperative blood loss (P = .015), lower blood transfusion rate (P = .035), and less hepatic portal block time (P = .012).
Conclusions:
Applying intraoperative ultrasound in laparoscopic liver resection for hepatic pedicle occlusion is a safe, simple, and effective method.
