Application of molecular absorbent recycling system in auto liver transplantation / 中华肝胆外科杂志

ABSTRACT

Objective To investigate the application of molecular absorbent recycling system (MARS) in auto liver transplantation (ALT).Methods The clinical data of 46 patients who underwent ALT in Zhongnan Hospital of Wuhan University from September 2014 to August 2015 were retrospectively studied.The patients were randomly divided into the MARS group (n =30) and the hemodialysis group (n =16).In the MARS group,20 patients were male and 10 were female with an average age of (15 ±67) years,and the median age was 46.In the hemodialysis group,8 were male and 8 were female with an average age of (22 ± 54) years.A heparinized left iliac vein was linked to a centrifugal pump of a MARS and an output tube was linked to a left jugular vein.Before the anhepatic phase,physical pretreatment was carried out by ligating the porta hepatis and inferior vena cava (IVC) to adapt the patient to the anhepatic phase.Subsequently,a bypass was established followed by ligation of the IVC.The duration of operation,length of stay in ICU after operation,one-year survival rate and hepatorenal function were studied.Results The duration of operation in the MRAS group and in the hemodialysis group was not significantly different (P ＞0.05).The length of stay in ICU after operation in the MARS group was (12.0 ±3.0) d,which was significantly shorter than that of the hemodialysis group (20.0 ± 2.0) d (P ＜ 0.05).The one-year survival rate in the MARS group was (100％),which was significantly higher than that of the hemodialysis group (93.8％,P ＜0.05).Conclusion The application of MARS in ALT shortened the length of stay in hospital and improved one-year survival rate,resulting in better outcomes than the conventional method.
