BACKGROUND: Pancreaticoduodenectomy (PD) remains the cornerstone of managing pancreatic ductal adenocarcinoma (PDAC) of the pancreas head/neck, but it is associated with high morbidity. We hypothesize that, in absence of pancreatectomy-specific morbidity (PSM), minimally invasive PD (MIPD) provides improved short-term outcomes compared to open PD (OPD). METHODS: NSQIP pancreatectomy-targeted database 2014-2019 was utilized. PSM was defined as the occurrence of delayed gastric emptying (DGE) and/or post-operative pancreatic fistula (POPF). The cohort was divided into No-PSM and PSM groups. Propensity score match was applied in each group to compare outcomes of MIPD vs. OPD. RESULTS: 8,121 patients were selected. Patients were divided into No-PSM (N = 6267) and PSM (N = 1854) groups. In No-PSM group, we matched 1656 OPD to 552 MIPD patients. MIPD had longer operations (423 vs. 359 min; p < 0.001) but less overall morbidity (22.1% vs. 29.1%; p = 0.001) mostly attributed to less bleeding and sepsis. MIPD patients also had a one-day shorter median LOS (6 vs. 7 days; p = 0.005) and higher rates of home discharge (92.8% vs. 89.6%; p = 0.027). No difference was noted in mortality and 30-day readmission. In PSM group, 441 OPD were matched to 147 MIPD peers. MIPD had longer operations but without short-term benefits. General morbidity (61.2% vs. 61.9%), median LOS (12 vs. 12 days), mortality (2.7% vs. 1.8%), and readmission rates (32.7% vs. 26.5%) were similar. Same conclusions were drawn in the per-protocol analysis. CONCLUSION: PSM is common following PD for PDAC. In the absence of PSM, MIPD is associated with less postoperative morbidity and shorter LOS.
