Abstract

Background

Laparoscopic distal pancreatectomy (LDP) has been shown to provide short-term clinical outcomes similar to open distal pancreatectomy (ODP) for patients with benign tumors. Our aim was to better define oncologic outcomes and long-term survival profiles following LDP for pancreatic ductal adenocarcinoma (PDAC).

Methods

We queried the National Cancer Database to identify patients with pathologic stage I–III PDAC who underwent distal pancreatectomy between 2010 and 2013. Logistic regression was performed to examine predictors of oncologic outcomes. Cox modeling was used for survival analysis and to estimate median overall survival (OS).

Results

One thousand five hundred fifty-four patients were included in the analysis. Patients undergoing LDP and ODP demonstrated identical probabilities of an adequate lymph node sampling and 90-day mortality. Those undergoing LDP demonstrated an increased probability of margin-negative resection (OR 1.78, CI 1.25–2.52) and a decreased probability of a prolonged hospital stay (OR 0.55, CI 0.32–0.95) or readmission (OR 0.56, CI 0.33–0.95) relative to those undergoing ODP. There was no difference in OS between groups (29.6 vs. 23.8 months, p = 0.10).

Conclusion

LDP is an effective modality for managing resectable cancer in the pancreatic body and tail. LDP provides short-term oncologic outcomes and long-term OS rates identical to those for ODP while affording an accelerated recovery.
