Abstract

Background: Single-port laparoscopic approaches are well established in the field of minimally invasive surgery; however, single-port laparoscopic distal pancreatectomy (SPLDP) has not been evaluated in a large number of distal pancreatic neoplasms. We aimed to compare single-port laparoscopic distal pancreatectomy outcomes with conventional laparoscopic distal pancreatectomy (LDP) outcomes. Methods: We retrospectively evaluated the medical records of 101 patients who underwent SPLDP (n = 26) or LDP (n = 75). We performed 1:1 propensity score matching between the two groups. Consequently, 26 patients were included in each group. We analyzed the learning curve based on the operation time in SPLDP. Results: Single-port laparoscopic distal pancreatectomy could be performed with fewer trocars (P < 0.001) and assistants (P < 0.001). However, compared to the LDP group, mean operation time was longer (278.9 vs. 178.7 min, P < 0.001) and splenic vessel preservation rates were lower (0% vs. 46.2%, P < 0.001) in the SPLDP group. The mean pain visual analogue scale score was significantly lower at postoperative day 1 (P < 0.001) and day 2 (P < 0.001) in the SPLDP group. The learning curve was determined in the 12th case for SPLDP. Conclusions: Single-port laparoscopic distal pancreatectomy is comparable in safety to conventional laparoscopic approaches for distal pancreatic neoplasms, with fewer trocars, assistants and less pain; however, operation time was longer.
