Abstract:
Objective:To analyze curative efficacy and pronosis of three-dimensional reconstruction combined with 3D printing assisted minimally invasive surgery in the treatment of hepatolithiasis.Methods:92 patients with complex hepatolithiasis treated by minimally invasive surgery in Qingdao Hospital affiliated to Shandong First Medical University from November 2018 to January 2020 were retrospectively selected. According to different surgical positioning methods, they were divided into the control group [50 cases , conventional computer tomography (CT) positioning] and the observation group (42 cases, 3D reconstruction combined with 3D printing technology). The curative effect, stone residue rate, operation related indexes, complications and recurrence rate were compared between the two groups.Results:The excellent and good rate of the observation group was higher than that of the control group (95.2% vs 80.0%), and the rate of residual stones after surgery was lower than that of the control group (4.0% vs 22.0%), with statistically significant difference (both P<0.05). Compared with the control group, the observation group had shorter operation time, less intraoperative blood loss and postoperative abdominal drainage volume, shorter postoperative abdominal drainage time and hospital stay, with statistically significant difference (all P<0.05). The incidence of postoperative complications and recurrence rate in the observation group were lower than those in the control group (11.9% vs 30.0%, 2.4% vs 18.0%), with statistically significant difference (both P<0.05). Conclusions:Three-dimensional reconstruction combined with 3D printing assisted minimally invasive surgery is effective in the treatment of complex hepatolithiasis and can reduce the recurrence rate.
