[Application of laparoscopic transection of median hepatic fissure in difficult laparoscopic liver resections].
Objective:The aim was to explore the strategy and clinical value of laparoscopic transection of median hepatic fissure (MHF) in difficult laparoscopic liver resections.Methods:First the MHF was located and marked, then the transection plane of the MHF was set. Next, the laparoscopic Multifuctional Operative Dissector (LPMOD) and the technique of curettage and aspiration were utilized to transect the liver beginning from the middle portion of the gallbladder fossa, in a caudal-to-cranial and anterior-to-posterior direction, until the clear exposure of the anterior surface of the intrahepatic inferior vena cava. Transection of the MHF was accurately achieved. Finally, dissection of the second and third porta hepatis were carefully performed and mobilization of the transected liver was achieved. This technique of laparoscopic transection of MHF was successfully performed in 13 patients in difficult laparoscopic liver resections.Results:Between April 2014 and August 2015, 13 patients received the technique of laparoscopic transection of MHF in difficult laparoscopic liver resections, including 10 cases of laparoscopic right hepatectomy, two cases of laparoscopic left hepatectomy and one case of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS). The maximum size of the transected tumor was 15 centimeter. Duration of surgery was 240-430 min[Mean, 324.4±50.0]; the time for transection of the MHF was 40-118 min[mean, 66.4±22.7]. Blood loss was 200-2 000 ml[583.3±452.9]. The length of postoperative hospital stay was 6-25 days[mean, 13.2±5.2]. Seven patients received intraoperative transfusions. No postoperative intraabdominal bleeding, liver failure or other severe postoperative complications occurred. No perioperative death occurred.Conclusions:Application of laparoscopic transection of the MHF in difficult laparoscopic liver resections can help to clearly expose the second and third porta hepatis, especially in patients who have huge tumors and poor exposure for hepatic dissection. Moreover, precise location and transection of the MHF remains very important strategies of applying this technique.
