Three-dimensional visualization technology in the use of laparoscopic spleen-preserving distal pancreatectomy / 中华普通外科杂志

ABSTRACT

Objective:To evaluate three-dimensional visualization technology (3D technic) used in laparoscopic spleen-preserving distal pancreatectomy for pancreatic benign or low-grade malignant tumors.Methods:Data of 28 patients with laparoscopic distal pancreatectomy at Beijing Hospital from Aug 2016 to Dec 2021 were retrospectively analyzed.Results:There were 12 patients assigned in 3D attempt compared to 16 patients undergoing ordinary laparoscopy. In 3D group, all 12 patients underwent successful spleen preserving distal pancreatectomy. While in control group only 5 cases were successful in spleen preserving procedure, the remaining 11 cases failed in spleen preserving ending up in distal pancreatectomy combined with splenectomy. The spleen preserving pancreatectomy rate in 3D group was higher than control group ( P<0.05). There was no significant difference in the operation time (202±53.8) min vs. (186.8±48.3) min, intraoperative blood loss (107.5±141.2) mL vs. (160.6±184.4) ml and the incidence of pancreatic leakage between the two groups ( P>0.05). Nor there was difference in the average postoperative hospital stay between the two groups [(9.6±2.5) d vs. (19.1±40.6) d] ( P>0.05). Conclusion:Three dimensional visualization technology can improve the success rate and safety of laparoscopic spleen preserving distal pancreatectomy in cases of benign and low-grade malignant distal pancreatic tumors.
