Laparoscopic ultrasound guided laparoscopic liver resection / 中华肝胆外科杂志

ABSTRACT

Objective To study the use of laparoscopic ultrasound (LUS) in laparoscopic liver resection (LLR).Methods Patients who underwent LLR in PLA General Hospital from Jan 2013 to Jan 2017 were retrospectively collected and analyzed.LUS detection was routinely performed to identify tumor and important vessels,determine the margin of liver resection and guide in parenchymal transection.Results 324 patients underwent LLR during the study period.The resections included 137 bisegmentectomies S2-3 (33.0％),62 segrnentectomies (19.1％),59 right or left hepatectomies (18.2％),45 wedge resections (13.9％) and 21 other types of bi-or tri-segmentectomies.The median duration of surgery was 3.3 h (1 ～ 10 h).The median operative blood loss was 125.0 ml (5 ～ 1 200 ml).Intraoperative complications were rare.The total conversion rate was 2.2％ (7 patients).Postoperative complications occurred in 23.7％ of patients,all grade 1 ～2 according to the Clavien-Dindo classification.No liver-related mortality occurred.The R0 resection rate of malignant tumors was 100％.The median postoperative hospital stay was 5.0 days (1 ～ 15 days).Conclusions The safety and efficacy of LLR were improved by the full-time and real-time use of intraoperative LUS.There is a need for intraoperative LUS training for liver surgeons.
