    Abstract:
    BACKGROUND: Minimally invasive distal pancreatectomy (MIDP) is associated with improved peri-operative outcomes compared to the open approach, though cost-effectiveness of MIDP remains unclear. METHODS: Patients with pancreatic tumors undergoing open (ODP), robotic (RDP), or laparoscopic distal pancreatectomy (LDP) between 2012-2014 were identified through the Truven Health MarketScan® Database. Median costs (payments) for the index operation and 90-day readmissions were calculated. Multivariable regression was used to predict associations with log 90-day payments. RESULTS: 693 patients underwent ODP, 146 underwent LDP, and 53 RDP. Compared to ODP, LDP and RDP resulted in shorter median length of stay (6 d. ODP vs. 5 d. RDP vs. 4 d. LDP, p<0.01) and lower median payments ($38,350 ODP vs. $34,870 RDP vs. $32,148 LDP, p<0.01) during the index hospitalization. Total median 90-day payments remained significantly lower for both minimally invasive approaches ($40,549 ODP vs. $35,160 RDP vs. $32,797 LDP, p<0.01). On multivariable analysis, LDP and RDP resulted in 90-day cost savings of 21% and 25% relative to ODP, equating to an amount of $8,500-$10,000. CONCLUSION: MIDP is associated with >$8,500 in lower cost compared to the open approach. Quality improvement initiatives in DP should ensure that lack of training and technical skill are not barriers to MIDP.
