Robotic versus laparoscopic distal pancreatectomy for left-sided pancreatic tumors: a single surgeon’s experience of 228 consecutive cases

Laparoscopic distal pancreatectomy (LDP) has gained popularity for the treatment of left-sided pancreatic tumors. Robotic systems represent the most recent advancement in minimally invasive surgical treatment for such tumors. Theoretically, robotic systems are considered to have several advantages over laparoscopic systems. However, there have been few studies comparing both systems in the treatment of distal pancreatectomy. We compared perioperative and oncological outcomes between the two treatment modalities.
A retrospective analysis was conducted of all consecutive minimally invasive distal pancreatectomy cases performed by a single surgeon at a high-volume center between January 2015 and December 2017.
The analysis included 228 consecutive patients (LDP, n = 182; Robotic-assisted laparoscopic distal pancreatectomy [R-LDP], n = 46). Operative time was significantly longer in the R-LDP group than in the LDP group (166.4 vs. 140.7 min; p = 0.001). In a subgroup analysis of patients who underwent the spleen-preserving approach, the spleen preservation rate associated with R-LDP was significantly higher than that associated with LDP (96.8% vs. 82.5%; p = 0.02). In another subgroup analysis of patients with pancreatic cancer, there were no significant differences in median overall and disease-free survival between the two groups.
R-LDP is a safe and feasible approach with perioperative and oncological outcomes comparable to those of LDP. R-LDP offers an added technical advantage that enables the surgeon to perform a complex procedure with good ergonomic comfort.
