Background: Laparoscopic pancreatectomy (LP) is increasingly performed with several institutional series and comparative studies reported. We have applied LP to a variety of pancreatic resections since 2004. This article is to report results of 15-year practice of 605 LPs for pancreatic and periampullary diseases. Methods: Patients with benign or malignant diseases in the pancreas and periampullary region, who underwent LP from June 2004 to June 2018, were retrospectively reviewed. The demographics and indications, and intraoperative and perioperative outcomes were evaluated. Results: A total of 605 consecutive LPs were analyzed, including 237 (39.2%) distal pancreatectomy with splenectomy (DPS), 116 (19.2%) spleen-preserving distal pancreatectomy (SPDP), 30 (5.0%) enucleation (EN), 30 (5.0%) central pancreatectomy (CP), 186 (30.7%) pancreatoduodenectomy (PD), and 6 (1.0%) pancreatoduodenectomy with total pancreatectomy (PDTP). The most common pathologic finding was pancreatic ductal adenocarcinomas (146, 24.1%). Conversion to open procedure was required in 22 patients (3.6%) (12 with PD, 8 with DPS, 1 with CP, and 1 with PDTP). The mean operative time was 241.5 ± 105.5 minutes (range 50-550 minutes) for the entire population and 367.1 ± 61.8 minutes (range 230-550 minutes) for PD. Clinically significant pancreatic fistula (ISGPF grade B and C) rate was 12.4% for the entire cohort and 16.1% for PD. Rate of Clavien-Dindo III-V complications was 17.4% for the entire cohort and 23.7% for PD. Ninety-day mortality was observed only in the cohort of patients undergoing PD (n = 4). Conclusions: The LP procedure appears to be technically safe and feasible, with an acceptable rate of morbidity when performed at our experienced, high-volume center. However, PD has less favorable outcomes and needs further evaluation.
