Left liver anatomical resection via left vertical groove by laparoscope / 中华普通外科杂志

ABSTRACT

Objective To evaluate left liver anatomical resection via left vertical groove by laparoscope.Method Among 103 patients with left intrahepatic biliary calculi,39 cases underwent left lateral hepatectomy,20 cases did left liver anatomical resection via left vertical groove by laparoscope,29 cases underwent left lateral hepatectomy via left liver diaphragmatic surface,15 cases did left liver anatomical resection via the first porta.Result In the 103 cases of laparoscopic left liver anatomical resection,101 cases were successful and two cases were conversed to open surgery.In the success group,total laparoscopic anatomical left lateral lobectomy was performed (Ⅱ,Ⅲ section) in 68 cases.Compared with the approach via left liver falciform ligament diaphragmatic surface,the operatve time via left vertical groove was significantly shorter(t =-2.723,P =0.008,intraoperative blood loss was significantly smaller (t =-5.399,P =0.000),while the differences in postoperative hospital stay (t =-0.168,P =0.867) and postoperative complications (x2 =0.664,P =0.415) were of no statistical significance between the 2 groups.In the 33 cases of left hemihepatectomy (Ⅱ,Ⅲ,Ⅳ section),those performed via left vertical groove compared with through the first porta hepatic,used shorter operation time(t =-3.144,P =0.004),while blood loss was similar(t =-1.049,P =0.302),as well as the length of hospital stay(t =0.784,P =0.439).There was no postoperative bleeding and intractable bile leakage,nor postoperative air embolism.Flatus on an average of (2.5 ± 1.2) days.Patients were discharged from hospital 5-17 (9.98 ±2.98) days post-op.96 cases were followed up in the 101 cases undergoing successful total laparoscopic left hemihepatectomy.The followed-up time were 3-52 (32.6 ± 5.7) months.Postoperative review found no residue stone.One case in first porta hepatis group,caudate lobe atrophy was found by postoperative CT.Conclusions Left liver anatomical resection via left vertical groove by laparoscope is less traumatic,quick recovery with satisfactory clinical curative effect for the treatment of left hepatolithiasis.
