 Abstract
Backgrounds/Aims: The purpose of this study is to demonstrate that laparoscopic distal pancreatectomy in benign disease is is safer and more favorable to patients than open distal pancreatectomy.
Methods: We retrospectively reviewed data of 150 patients who underwent laparoscopic (n=69) or open (=81) distal pancreatectomy at a double institutes from 2008 to 2018. We reviewed each patient’s history for age, sex, pathologic diagnosis. Specific outcomes that were included hospital stay, operative time (in minutes), operative blood loss (in milliliters), 30-daymajormorbidity and mortality (Clavian-Dindo classification), pancreatic leak rate (grade of leak A, B, or C), pancreatic hemorrhage.
Results: From 2008 to 2018, there were 150 patients underwent distal pancreatectomy with or without splenectomy for benign pancreatic disease. 81 patients underwent open and 69 patients underwent laparoscopic distal pancreatectomy (LDP) Intra-operative estimated blood loss was significantly lower in the LDP group than in the OPD group (200 vs. 400 ml p<0.01). There was no difference in blood transfusion between the two groups. There was a significant difference in the resection method between the two groups (p<0.01) and there was a significant difference in the use of mesh for prevention of postoperative pancreatic fistula (POPF) (53 vs. 34 p<0.01). There was no significant difference in incidence of POPF (15.9% in LDP vs 7.4% in ODP, ,p=0.235) between the two groups, morbidity rate between the two groups (18 vs. 30 p=0.152), post - pancreatectomy hemorrhage, wound infection, hospital stay and readmission.
Conclusions: LDP showed there was no difference in the occurrence of POPF, complication and hospital stay. In contrast, intra-operative blood loss was significantly lower in the LDP group than in the ODP group, and LDP was also significantly better in the view point of the feeding advance. In other words, LDP is safer and more favorable to patients than ODP.
