Application of three-dimensional visualization technology in surgical resection of caudate lobe tumor

Abstract

Objective To evaluate the precision of hepatectomy by preoperative planning of preoperative liver three-dimensional visualization. Methods Seventy-five patients with caudate lobe liver tumor underwent preoperative three-dimensional visualization surgery planning. Preoperative planning and intraoperative operation were compared. Total liver volume, normal liver volume and residual functional liver volume were calculated, method of hepatectomy, duration of operation, time of occlusion, volume of bleeding, transfusion and the postoperative complications were recorded. Results The preoperative three-dimensional reconstruction model was used to simulate surgical resection. The volume of liver resection was 263.89 mL (33.76, 1 650.85), and the residual functional liver volume was 1 189.67 mL (529.79, 1 859.72), 27 patients received caudate lobe liver resection only, 6 patients received left plus caudate lobe resection, 14 patients received partial right(Ⅵ, Ⅶ section) plus caudate lobe resection, 20 patients received right plus caudate lobe resection, 8 patients received middle(Ⅳ, Ⅴ and Ⅷ section) plus caudate lobe resection, Pringle's maneuver 25(0, 62)min, bleeding 300(100, 3 600)mL, operating duration 198(116, 388)min, 11 patients receive blood transfusion, amount of transfusion 600(200, 3 000)mL. All patients successfully performed tumor resection according to preoperative planning. There were no massive hemorrhage and air embolism in the patients. One case of ISGLS I complications after operation were successfully recovered after caesarean section, and all the remaining patients were discharged from hospital smoothly. Conclusions With accurate preoperative planning, the resection range can be accurately mastered, the main vessels are avoided, intraoperative bleeding and the maintenance of postoperative liver function can be controlled.
