Objective To investigate the clinical application effect of descending hilar plate technology in laparoscopic heminephrectomy for intrahepatic bile duct calculus.Methods The clinical data of 40 patients with intrahepatic bile duct calculus who underwent laparoscopic heminephrectomy in our hospital from January 2015 to December 2019 were retrospectively analyzed. The patients were grouped according to different surgical procedures, 21 patients with Pringle method of total hepatic vascular exclusion were classified in the control group, and 19 patients with descending hilar plate technology of blood occlusion technology were classified in the observation group. The operation time, intraoperative bleeding volume, postoperative hospital stays, liver function recovery, and postoperative complications were compared between the two groups.Results There was no statistically significant difference between the two groups in the intraoperative bleeding volume and operation time (P>0.05), but the postoperative hospital stays in the observation group shortened (P=0.025). The changes on the ALT, TB, and AST in the observation group was obvious than those of the control group (P<0.05). There was no statistically significant incidence between the two groups in the total incidence of complications (P=0.128).Conclusions Compared with Pringle method of total hepatic vascular exclusion, descending hilar plate technology in laparoscopic heminephrectomy can fully expose the Glisson pedicles of the left and right livers, and it is convenient to implement hemihepatic blood flow occlusion. It has less damage to healthy side of the liver and quicker liver function recovery, and it can reduce postoperative complications and shorten postoperative hospital stay.
