ABSTRACT
Objective To evaluate the application value of anterior approach right hepatectomy using the liver hanging maneuver for severe blunt liver trauma.Methods Clinical data of 63 patients with severe blunt liver trauma undergoing right hepatectomy in our hospital from January 2011 to January 2017 were retrospectively analyzed.Among them,31 patients received anterior approach right hepatectomy (anterior approach group,31 cases) while the others did conventional right hepatectomy (conventional approach group,32 cases).Clinical data,intraoperative blood loss,postoperative alanine transaminase (ALT) at POD3,postoperative morbidity and mortality in both groups were analyzed and compared.Results There were eight surgical deaths,one in the anterior approach group and seven in the conventional approach group.All the 31 cases underwent anterior approach right hepatectomy successfully using the liver hanging maneuver.The mean intraoperative blood loss (768 ± 231) ml vs.(1 264 ± 1 248) ml (P ＜ 0.05),postoperative hepatic function ALT value at POD3 (155 ± 89) U/L vs.(689 ± 67) U/L (P ＜ 0.05),postoperative morbidity and mortality of the anterior approach group were markedly superior to conventional approach group (12.9％ vs.34.4％,3.2％ vs.21.9％,all P ＜ 0.05).Conclusions Anterior approach right hepateetomy using the liver hanging maneuver has advantages of decreased intraoperative blood loss,less hepatic function compromise,reduced postoperative morbidity and mortality compared to conventional approach right hepatectomy in cases of severe right liver blunt trauma.
ABSTRACT
Objective To evaluate the safety of mesohepatectomy for centrally located large hepatic tumors.Methods The clinical data of 37 patients who underwent hepatectomy for centrally located large liver tumors in our hospital from October 2010 to August 2015 were retrospectively analyzed.During the operation,the left and right hemilivers were mobilized.Slings for the improved liver hanging maneuver and for selective hepatic vascular occlusion were placed.These slings were used when necessary in order to minimize occlusion and ischemia time to the residual liver,and to maximize the volume of functional liver remnant.Mesohepatectomy was carried out using a microwave hemostatic separator.The feasibility,its effects on preventing hemorrhage,the degree of liver damage and the postoperative complications were evaluated.Results The mean diameter of the neoplasms was (12.6 ± 7.2) cm.The vascular inflow occlusion time of the left and right hemilivers were (12.2 ±3.5) min and (18.5 ±7.1) min,respectively.The blood loss was (487 ± 352) ml.The amount of red blood cell transfusion was (2.7 ± 1.9) U.The operation time was (215 ± 72) min.TBIL,ALT and AST reached their peak levels on the 1 st day after operation and they were higher than before surgery (P ＜ 0.01).The levels were then significantly decreased on the 3rd day after operation.However,the TBIL (P ＜ 0.05),ALT (P ＜ 0.01) and AST (P ＜ 0.05) were higher than the preoperative level,and only returned to normal or were close to the preoperative value on the 7th day after operation (P ＞ 0.05).The initial increase in ALT was quick and then it slowed down,while the initial increase in AST was slow but it decreased quickly.Conclusions Mesohepatectomy for centrally located large hepatic tumors could safely be carried out using the liver hanging maneuver combined with selective hepatic vascular occlusion and a microwave hemostatic separator.This method has the advantages of causing less bleeding,liver damage and rapid recovery.
ABSTRACT
Liver hanging maneuver was firstly introduced by Belghiti et al in 2001,since then,the new technique has aroused widespread interest.The fatal weakness of liver hanging maneuver is bleeding resulting from blind dissection of the anterior plane of the inferior vena cava.In this review,the anatomic basis of retrohepatic tunnel and the surgical techniques were summarized to provide surgeons with suggestions in hepatectomy,liver transplantation or operations for hepatic trauma,so as to reduce the incidence of complications and raise the safety and success rate.
ABSTRACT
Liver hanging maneuver(LHM)was first performed to assist right hepateetomy by Jacques Belghiti in 2001.During the procedure of hepatectomy,the liver is lifted by a tape which passes between the anterior Surface of the inferior vena cava and the liver.LHM provides effective vascular control and makes the anterior approach safer and easier.As one of the most important innovations in the field of liver resection,LHM has some definite advantages over the classical approach,including less hemorrhage,less tumoral manipulation and rupture,better hemodynamic stability,reduced ischemic damage of the liver remnant and better survival for patients with hepatocellular carcinoma.Moreover,LHM can serve as a guide to the correct analomical transection plane,and help to improve the exposure of the deep parenchymal plane.LHM developed rapidly in the past few years and it has been widely adopted not only in the treatment of liver cancer,but also in living donor liver transplanration,orthotopic liver transplantation and the treatment of benign liver diseases.Furthermore,many surgeons utilize LHM to facilitate various anatomical liver resections.Although the concept of LHM is widely accepted,its limits and contraindications still need to be investigated in the future.
ABSTRACT
Objective To introduce the application of double liver hanging maneuver in anatomical right hemihepatectomy and share our own experience. Methods Twenty-four patients underwent right hemihepatectomy using double liver hanging maneuver, and the data were collected prospectively after operation. Another 49 patients underwent right hemihepatectomy using the traditional methods,serving as the control group. Results Retrohepatic tunnel was constructed in 27 patients, double liver hanging maneuver was successfully performed in 24 anatomical right hemihepatomy and failed in 3 patients due to the near proximity between the tumor and the middle line. Compared with the control group, blood loss was much less (t=3. 191 ,P＜0.05), ALT and liver function recovered more quickly postoperatively and the difference in operative duration between the 2 groups was not significant (t=-1. 695,P＞0. 05). There was about 1-2 cm wide space located between retrohepatic IVC and dorsal liver when the 2 tapes were tracted, and no injury in hepatic short veins and retrohepatic IVC occurred during the operation. Conclusion The double liver hanging maneuver can make anatomical right hemihepatectomy more accessible and safe.
ABSTRACT
PURPOSE: The liver hanging maneuver (LHM) is a useful technique enabling a safe anterior approach, which is one of the most important innovations in the field of major hepatic resections. This study was conducted to review tumors' profiles after applying this procedure and to evaluate the usefulness of LHM and Glissonean pedicle transaction method (GPTM). METHODS: Medical records of 64 patients who underwent hepatic resection using LHM and GPTM at the Asan Medical Center were reviewed. The classic LHM was conducted according to the Belghiti method. RESULTS: Among 64 patients, 46 patients had hepatocellular carcinoma; 7, intrahpatic cholangiocarcinoma; 4, hilar cholangiocarcinoma; 4, metastatic liver cancer; 3, benign liver tumor. Mean tumor size was 10.6 cm (3~22). Mean liver parenchymal transection time was 20 min (15~30). Right side hepatectomy was performed in 44 patients; left side hepatectomy with or without caudate lobe was performed in 19 patients. Twenty patients (31.3%) required blood transfusion during surgery. There was no in-hospital mortality or major complications. Minor complications developed in 6 patients (9.37%). CONCLUSION: GPTM and LHM are a safe and useful surgical application of various anatomical resections for huge liver tumor and an effective procedure during left hepatectomy with or without caudate lobe.
