Intercostal trocars and transthoracic trocars facilitated laparoscopic resection of lesions in liver segments 7 and 8 : a report of 20 cases / 中华肝胆外科杂志

ABSTRACT

Objective To evaluate the use of intercostal trocars (ICS) and transthoracic trocars in laparoscopic resection of liver segments 7 and 8.Method From November 2015 to June 2017,20 patients who underwent laparoscopic S7 or 8 segmentectomy for liver tumors in the Department of Hepatobiliary Surgery,the First Affiliated Hospital,Guangxi Medical University were analyzed retrospectively.Results Ports were inserted at the 8th or 9th ICS,respectively,in addition to the conventional abdominal ports.The mean operation time was 225.0 min (110.0 ～ 486.0 min).Anatomical resection was completed in 1 patient,and non-anatomical resection in 19 patients.The conversion rate was 0％.Pringle's maneuver was used in 9 patients.The mean blood loss was 85.0 (25.0 ～410.0) ml,and the mean length of hospital stay was 7.0 (5.0 ～ 12.0) days.The complication rate was 10.0％.Pathologic findings revealed that 17,2,1 patient(s) had HCC,hemangioma,and inflammatory nodule,respectively.The mean tumor size and tumor free margin were 33.8 (15.0 ～ 74.0) mm;and 15.0 (1.0 ～ 30.0) mm,respectively.There was no HCC recurrence on follow-up,expect for one patient who developed tumor recurrence at 20 months after laparoscopic liver resection.Conclusions In selected patients,laparoscopic liver resection using intercostal trocars was useful and safe for tumors located in liver segments 7 and 8.The long-term oncologic outcomes need to be further evaluated.
