Abstract
BACKGROUND: Laparoscopy is widely accepted as a feasible option for distal pancreatectomy. However, the experience in laparoscopic distal pancreatectomy (LDP) for pancreatic ductal adenocarcinoma (PDAC) is limited to a small number of studies, reported by expert centers. The present study aimed to evaluate perioperative and oncological outcomes after LDP for PDAC in a large, multicenter cohort of patients. METHODS: A retrospective analysis of the data on 196 patients with histologically verified PDAC, operated at Oslo University Hospital-Rikshospitalet (Oslo, Norway), Asan Medical Center (Seoul, Republic of Korea), Institut Mutualiste Montsouris (Paris, France) and University Hospital Southampton (Southampton, UK) between January 2002 and April 2015 was conducted. The patients with standard (SLDP) and extended (i.e., en bloc with adjacent organ, ELDP) resections were compared in terms of perioperative and oncological outcomes. RESULTS: Out of 196 LDP procedures, 191 (97.4 %) were completed through laparoscopy, while five (2.6 %) were converted to open surgery. ELDP was performed in 30 (15.7 %) cases. Sixty-one (31.9 %) patients experienced postoperative complications, including 48 (25.1 %) with pancreatic fistula. The rate of clinically relevant fistula (grade B/C) was 15.7 %. Median postoperative hospital stay was 8 (2-63) days. Median follow-up was 16 months. Median survival was 31.3 months (95 % CI 22.9-39.6). Three- and 5-year actuarial survival rates were 42.4 and 30 %, respectively. SLDP was associated with significantly higher survival compared with ELDP (p = 0.032). CONCLUSIONS: LDP seems to be a feasible and safe procedure, providing satisfactory oncological outcomes in patients with PDAC.
