Objective: To compare the clinical application of three-dimensional laparoscopic pancreatoduodenectomy (3D-LPD) with that of two-dimensional laparoscopic pancreatoduodenectomy (2D-LPD), and to explore the safety and feasibility of 3D-LPD. Methods: A retrospective analysis was made from the data of 45 patients with 3D-LPD and 45 patients with 2D-LPD who underwent total laparoscopic pancreatoduodenectomy from March 2017 to August 2018 at Department of Hepato-Pancreato-Biliary Surgery, the First People's Hospital of Changzhou.The differences of intraoperative conditions, postoperative complications and postoperative pathological findings between the two methods were compared.Measurement data were compared with independent sample t-test, enumeration data were statistically analyzed with Chi-square test or Fisher exact probability. Results: The operation time of 3D-LPD group was shorter than that of 2D-LPD group ((335±95) min vs. (419±113) min, t=-3.817, P=0.000), which mainly showed that the time of digestive tract reconstruction was reduced ((92±26) min vs. (131±46) min, t=-4.951, P=0.000). The intraoperative blood loss in the 3D-LPD group was significantly less than that in the 2D-LPD group ((242±124) ml vs. (350±176) ml, t=-3.365, P=0.001), and the perioperative blood transfusion in the 3D-LPD group was significantly less than that in the 2D-LPD group (χ(2)=4.444, P=0.035). Postoperative hospitalization days and ICU stay time were not significantly different between the two groups(both P>0.05). Postoperative complications such as pancreatic fistula, biliary fistula, postoperative bleeding, gastric emptying disorders, abdominal infection, were not significantly different between the two groups(all P>0.05). Conclusions: The operation time of 3D-LPD is shorter than that of 2D-LPD, and the amount of bleeding is less. Short-term clinical data showed that, 3D-LPD is effective, safe and worth popularizing.
