N2 - Objective:To quantify the nationwide impact of minimally invasive distal pancreatectomy (MIDP) on major morbidity as compared with open distal pancreatectomy (ODP).Background:A recent randomized controlled trial (RCT) demonstrated significant reduction in time to functional recovery after MIDP compared with ODP, but was not powered to assess potential risk reductions in major morbidity.Methods:International cohort study using the American College of Surgeons' National Quality Improvement Program (ACS-NSQIP) (88 centers; 2014-2016) to evaluate the association between surgical approach (MIDP vs ODP) and 30-day composite major morbidity (CMM; death or severe complications) with external model validation using Dutch Pancreatic Cancer Group data (17 centers; 2005-2016). Multivariable logistic regression assessed the impact of nationwide MIDP rates between 0% and 100% on postoperative CMM at conversion rates between 0% and 25%, using estimated marginal effects. A sensitivity analysis tested the impact at various scenarios and patient populations.Results:Of 2921 ACS-NSQIP patients, 1562 (53%) underwent MIDP with 18% conversion, and 1359 (47%) underwent ODP. MIDP was independently associated with reduced CMM [odds ratio (OR) 0.50, 95% confidence interval (CI) 0.42-0.60, P < 0.001], confirmed by external model validation (n = 637, P < 0.003). The association between rising MIDP implementation rates and falling postoperative morbidity was linear between 0% (all ODP) and 100% (all MIDP). The absolute risk reduction for CMM was 11% (95% CI 7.3%-15%) at observed conversion rates and improved to 14% (95% CI 11%-18%) as conversion approached 0%. Similar effects were seen across subgroups.Conclusion:This international study predicted a nationwide 11% risk reduction for CMM after MIDP versus ODP, which is likely to improve as conversion rates decrease. These findings confirm secondary outcomes of the recent LEOPARD RCT.
