Background:
Although laparoscopic surgery has many advantages, its application in pancreatic ductal adenocarcinoma has not been sufficiently studied. The objective of this study was to compare the surgical outcomes of laparoscopic distal pancreatectomy (LDP) to those of open distal pancreatectomy (ODP) for left-sided ductal adenocarcinoma.
Study Design:
Among 167 consecutive patients between December 2006 and August 2013, 150 patients were included. Unmatched and propensity score-matched analyses were performed to compare the primary (oncologic adequacy) and secondary outcomes (hospital course and complications) between ODP and LDP groups.
Results:
In unmatched patients, LDP was associated with an earlier return to diet and a shorter hospital stay compared with ODP. The 5-year survival rates were 27.6% in unmatched ODP (n = 80) and 32.5% in unmatched LDP (n = 70). Fifty-one patients from each group were selected by propensity score matching. In this matched patient comparison, LDP was again associated significantly with a shorter median postoperative time to restarting diet and a shorter hospital stay. The 2 groups did not differ significantly in terms of primary outcomes of operative time, number of harvested lymph nodes, resection margin status, and secondary outcomes of frequency of pancreatic fistula and complications. The 2 groups also had comparable patient survival (p = 0.91).
Conclusions:
This large single-center study of laparoscopic surgery for left-sided pancreatic ductal adenocarcinoma indicated that LDP was safe and more efficacious than OPD after propensity score adjustment for presurgical variables of return to diet and length of stay.
