Techniques of anatomical liver resection for hepatocellular carcinoma:a report of 125 cases / 中华消化外科杂志

ABSTRACT

Objective To summarize the techniques of anatomical liver resection for the treatment of hepatocellular carcinoma(HCC).Methods The clinical data of 125 patients with solitary HCC who underwent anatomical liver resection at the Zhongshan Hospital from January 2005 to December 2006 were retrospectively analysed.The inflow and outflow of hepatic segments to be resected were selectively clamped,then the main branches of portal vein and hepatic artery were ligated,and the ischemic hepatic segments were resected en bloc.Kelly forceps were used to crash and clamp the liver cut surface.The stumps of left and right hepatic ducts were continuously sutured with Prolene sutures.For tumors with the size above 10 cm in diameter,hepatectomy with anterior approach and liver hanging maneuver were adopted.Bile leakage was checked by injecting methylene blue or covering a gauze on the liver cut surface.Results The mean blood loss of all patients was 250 ml(100-6000 ml),and 32 of them needed blood transfusion.The morbidity was 23%(29/125).No patient died within 30 days after the operation,and 6%(5/83)of patients were found with residual tumor by postoperative arteriography.Conclusion Anatomical liver resection may improve the safety of operation,prevent the injury of great vessels and thus improve the efficacy.
