376 Background: Laparoscopic-assisted distal pancreatectomy (LDP) has improved perioperative outcomes over open distal pancreatectomy (ODP). Concerns regarding failure to achieve proper oncologic resection and compromised survival remain. Methods: Using the National Cancer Database (NCDB), we analyzed patients undergoing distal pancreatectomy for resectable pancreatic adenocarcinoma over a four-year period (2010-2014). Propensity score nearest-neighbor 1:1 matching (PSM) was performed between LDP and ODP patients based on age, sex, race, insurance, hospital volume, comorbidities, T-stage, N-stage, grade, neoadjuvant therapy, adjuvant therapy. Primary outcome was overall survival. Results: Of the 1,947 eligible patients, 605 (31%) underwent LDP. After PSM two well-balanced groups of 544 patients each were analyzed. There was a trend towards improved overall survival (OS) in patients undergoing LDP as compared to ODP (HR: 0.83, 95% CI 0.68-1.0; Median OS 29 vs. 23 months, p = 0.06). Patients undergoing ODP had a higher margin positive rate compared to those undergoing LDP (21.1% vs. 14.9%, p-value = 0.007). Overall conversion rate was 27%. Patients undergoing ODP had comparable outcomes to LDP in regards to median time to chemotherapy (50 vs. 48 days, p-value = 0.96); median nodes examined (12 vs. 12, p-value = 0.61); 30-day mortality (1.6% vs. 1.1%, p-value = 0.43); 90-day mortality (3.5% vs. 2.4%, p-value = 0.28); 30-day readmission rate (8.6% vs. 9.4%, p-value = 0.67). However, the median length of stay was shorter in the LDP group (6 vs. 7 days, p = 0.0001). Conclusions: In the absence of randomized trials, this is the largest comparative study demonstrating LDP as an acceptable alternative ODP, associated with a lower margin positive rate and shorter length of stay, and with no detriment in long term survival.
