[Regional vascular occlusion at hepatic hila for the resection of hepatic tumor--report of 63 cases].
A new operative procedure for hepatic segmentectomy was performed by dissecting the hepatic hila to occlude blood vessels to and from hemihepatis, one lobe or one segment which bore hepatoma. Forty-three liver cancers with 33 of them in stage IV, 4 metastatic liver cancers and 16 hemangiomas were resected by this method. The types of hepatic segmentectomy consisted of monosegmentectomy, multisegmentectomy, peripheral and central segmentectomy, segmentectomy after hepatic arteria embolization and resegmentectomy for recurrent hepatic cellular carcinoma etc. The vascular occlusion lasted as long as 120 minutes for the right portal vein and 70 minutes for the left. Intravenous infusion of extract from Salive mliltiorrhiza before vascular occlusion could prevent hepatic cells from reperfusion injury. The mentioned maneuvers resulted in mild postoperative liver dysfunction, rapid recovery and hepatocytes regeneration. Two patients died within 30 days postoperatively, constituting an operative mortality of 3.1%.
