AbstractLaparoscopic distal pancreatectomy (LDP) for benign and low-grade malignant pancreatic diseases has been increasingly utilized. However, the use of LDP for pancreatic ductal adenocarcinoma (PDAC) remains controversial and has not been widely accepted. In this study, the outcomes of LDP versus conventional open distal pancreatectomy (ODP) for left-sided PDAC were examined. A retrospective review of patients who underwent LDP or ODP for left-sided PDAC between January 2010 and January 2019 was conducted. One-to-one propensity score matching (PSM) was used to minimize selection biases by balancing factors including age, sex, ASA grade, tumor size, and combined resection. Demographic data, their pathological and short-term clinical parameters, and long-term oncological outcomes were compared between the LDP and ODP groups. A total of 197 patients with PDAC were enrolled. There were 115 (58.4%) patients in the LDP group and 82 (41.6%) patients in the ODP group. After 1:1 PSM, 66 well-matched patients in each group were evaluated. The LDP group had lesser blood loss (195 vs. 210 mL, p < 0.01), shorter operative time (193.6 vs. 217.5 min; p = 0.02), and shorter hospital stay (12 vs. 15 days, p < 0.01), whereas the overall complication rates were comparable between groups (10.6% vs.16.7%, p = 0.31). There were no significant differences between the LDP and ODP groups regarding 3-year recurrence-free or overall survival rate (p = 0.89 and p = 0.33, respectively). LDP in the treatment of left-sided PDAC is a technically safe, feasible and favorable approach in short-term surgical outcomes. Moreover, patients undergoing LDP than ODP for PDAC had comparable oncological metrics and similar middle-term survival rate.
