DOES ROBOTIC SYSTEM HAVE ADVANTAGES OVER LAPAROSCOPIC SYSTEM FOR DISTAL PANCREATECTOMY?

Division of Hepatobiliary and Pancreatic Surgery, Department of Surgery, University of Ulsan College of Medicine and Asan Medical Center, Seoul, South Korea

Background: Laparoscopic distal pancreatectomy (LDP) has been the best choice for the treatment of left-sided pancreatic lesions. Robotic systems provide an advanced surgical technique for minimally invasive surgery. Therefore, we compared the perioperative and short-term oncologic outcomes of robot-assisted LDP (RA-LDP) and conventional LDP.

Methods: A retrospective analysis was conducted of all consecutive minimally invasive distal pancreatectomy cases performed by a single surgeon at Asan Medical Center between October 2015 and October 2016.

Results: A total of 91 consecutive patients underwent minimally invasive distal pancreatectomy (LDP n = 61; RA-LDP n = 30). Most common pathologic finding was pancreatic ductal adenocarcinomas (36cases). There was no in-hospital mortality or cases of conversion to open surgery in this study. Spleen-preserving approach was performed more often in the RA-LDP (95%) than in the LDP (77.8%) groups (p = 0.132). Both groups showed no difference in complication rate (10% vs. 18%), postoperative hospital stay (7.6 ± 2.6 vs. 8.4 ± 3.1 days), and readmission rate (6.7% vs. 3.3%). Operative time was significantly longer in the RA-LDP group (171.2 ± 50.4 vs. 144.3 ± 50.1, p = 0.02). In a subgroup analysis on patients with completed spleen-preserving approach, there was no significant difference in operative time between the RA-LDP and LDP groups (165 ± 56.3 vs. 139 ± 36.5 min, p = 0.14). Both groups showed no significant differences in the total number of lymph nodes, number of positive lymph nodes, tumor differentiation, tumor stage, and resection margins.

Conclusions: RA-LDP is a safe and feasible approach that has an advantage of performing spleen-preserving distal pancreatectomy, with perioperative and short-term oncologic outcomes comparable to those of LDP.
