Abstract: Objective To explore the application value of three dimensional reconstruction technique in laparoscopic hepatectomy for hepatic carcinoma.Methods  From September 2019 to March 2022,the clinical data of 62 patients with primary hepatic carcinoma were gathered.The enhanced CT scanning was performed before surgery.Patients with three dimensiona reconstruction technology were set as observation group (n=31).Patients who did not use three dimensiona reconstruction technology were set as the control group (n=31),and intraoperative conditions (time of operation,bleeding volume during operation) and postoperative conditions (occurrence rate of postoperative complications,postoperative length of stay) of the two groups were compared.Results 62 patients successfully completed laparoscopic hepatectomy without liver failure or death.For patients with tumors located in liver segment Ⅱ and Ⅲ,there were no significant difference of operation time,intraoperative blood loss,postoperative hospital stay and postoperative complication total rate between control group and observation group（P＞0.05）.For patients with tumors located in liver segment Ⅳ-Ⅵ,operation time[（211.36±11.22）minutes vs （231.69±19.73 ）minutes],intraoperative blood loss[（274.29±23.84）ml vs （306.54±21.05）ml],postoperative hospital stay[（7.93±1.33）days vs （9.62±1.80）days] in observation group were lower than those in control group（P＜0.05）,and there was no significant difference of postoperative complication total rate between two groups（P＞0.05）.For patients with tumors located in liver segment Ⅰ,Ⅶ and Ⅷ,operation time[（165.88±10.60）minutes vs (187.30±17.29）minutes],intraoperative blood loss[（271.25±12.17）ml vs （308.00±28.21）ml],postoperative hospital stay[（7.63±0.74）days vs （9.30±1.06）days] in observation group were lower than those in control group（P＜0.05）,and there was no significant difference of postoperative complication total rate between two groups（P＞0.05）.Conclusion The three dimensiona reconstruction technique may have  prominent guiding significance for complex laparoscopic hepatectomy for hepatic carcinoma.
