Experiences in middle lobe hepatectomy

Objective To explore the technical knowhow and experience of mesohepatectomy for central region liver disease. Methods The clinical data of 86 patients with liver disease in central region undergoing mesohepatectomy were retrospectively analysed in Henan provincial People′s Hospital, including 49 males and 37 females. There were 47 cases of central liver cancer, 15 cases of hilar cholangiocarcinoma, 4 cases of hepatic hemangioma, 13 cases of gallbladder cancer, and 7 cases of intrahepatic cholangiolithiasis in central liver. 25 cases received accurate hepatectomy (group A) and 61 cases did irregular hepatectomy (group B). Results In group A , 15 cases did IV, V and VIII lobectomy, 10 cases underwent IV and V partial Lobectomy. Among the irregular hepatectomy group (group B), 35 were treated with hepatic middle lobe resection, 26 with local middle liver resection. There were significant differences in operation time, degree of postoperative liver function damage between the two groups (P<0.05) , while there was no difference in postoperative complications (P<0.05). Conclusions The accurate mesohepatectomy can reduce the incidence of postoperative liver function damage and surgical complications. Key words: Liver neoplasms; Cholelithiasis; Hepatectomy
