Abstract:
Objective:To study the effiacious based on our experience of precise anatomical hemi-hepatectomy strictly guided by the middle hepatic vein (MHV) for regional to treat intrahepatic hepatolithiasis.Methods:A retrospective analysis was conducted on the data of 47 patients with regional hepatolithiasis treated with hemihepatectomy from July 2015 to July 2019 at the Department of Hepatobiliary and Pancreatic Surgery, The University of Hong Kong-Shenzhen Hospital. The study included 15 males and 32 females, aged (42±15) years. The exposure and preservation of the MHV was included in the precision surgery group ( n=26), and failure to fully expose the MHV or damage to the MHV was included in the control group ( n=21). The operation time, intraoperative blood loss and other surgical data and postoperative complications of the two groups were compared. Results:All patients successfully completed the operation. There was no patient who developed liver failure, and no patient died 90 days after the operations. The operation time (5.2±1.8) h and intraoperative blood loss (620.5±450.8) ml of the precision surgery group were not significantly different from those of the control group (4.9±2.3) h and intraoperative blood loss (760.5±540.2) ml ( P>0.05). A total of 19 patients (40.4%) (7 in the precision surgery group and 12 in the control group) developed 36 post operative complications of various types. The postoperative complication rate in the control group was higher than that in the precision surgery group [47.6%(10/21) vs 19.2% (5/26)], the difference was significant ( P<0.05). All 47 patients were followed-up for 6 to 30 months. For postoperative long-term complications: 5 patients in the control group had residual stones, biliary tract infection, liver abscess, and biliary-enteric anastomosis stenosis with recurrence of stones, and only 2 patients in the precision surgery group were found to have residual stones and biliary-enteric anastomotic stenosis. Stone recurrence, (the incidence of long-term complication) in the control group was significantly higher than that in the precision surgery group [23.8% (5/21) vs 7.7% (2/26)], ( P<0.05). Conclusions:Precise anatomical hemi-hepatectomy strictly guided by MHV for regional hepatolithiasis could more fully remove stones and lesions, and reduced the rate of stone recurrence. It was safe and feasible with favorable efficacy.
