Application of helix hydro-jet in laparoscopic hepatectomy / 中华普通外科杂志

ABSTRACT

Objective To evaluate the application of helix hydro-jet in laparoscopic hepatectomy (LH).Methods Clinical data of 18 patients who underwent laparoscopic hepatectomy by helix hydro-jet were analyzed retrospectively.Results There were 18 cases including 9 cases of hepatic cavernous hemangioma,5 cases of primary hepatocellular carcinoma,2 cases of hepatic focal nodular hyperplasia,1 case of hepatic metastasis from colon carcinoma and 1 case of biliary cystadenoma in left liver.In 17 out of 18 patients laparoscopic hepatectomy was successfully completed by using helix hydro-jet.Only 1 patient was converted to open hepatectomy during operation due to uncontrollable hemorrhage from the branch of left hepatic vein.Partial hepatectomy was performed in 14 cases and hepatic left lateral hepatectomy was performed in 3 cases.Average intraoperative blood loss was 230 ml and average operation time was 170 minutes.No postoperative hemorrhage and hepatic function failure was observed.Postoperative bile leakage was observed in 1 patient,which was cured by drainage.Asymptomatic pleural effusions was found in 2 patients,necessitating no special intervention.The average hospital stay after the surgery was 5.6 days.5 patients with hepatocellular carcinoma were followed up for an average of 17 months and the patient converted to open hepatectomy suffered from tumor recurrence 13 month postoperatively.No implantation metastasis was observed on the trocar sites.Conclusions Laparoscopic hepatectomy by helix hydro-jet device can provide excellent visualization of vessels and bile ducts,which can assure the safe margin of hepatic neoplasm.No severe complications were observed.Laparoscopic hepatectomy by helix hydro-jet is a safe and feasible technique.
