Background: Minimally invasive distal pancreatectomy decreases time to functional recovery compared with open distal pancreatectomy, but the cost-effectiveness and impact on disease-specific quality of life have yet to be established.

Methods: The LEOPARD trial randomized patients to minimally invasive (robot-assisted or laparoscopic) or open distal pancreatectomy in 14 Dutch centres between April 2015 and March 2017. Use of hospital healthcare resources, complications and disease-specific quality of life were recorded up to 1 year after surgery. Unit costs of hospital healthcare resources were determined, and cost-effectiveness and cost-utility analyses were performed. Primary outcomes were the costs per day earlier functional recovery and per quality-adjusted life-year.

Results: All 104 patients who had a distal pancreatectomy (48 minimally invasive and 56 open) in the trial were included in this study. Patients who underwent a robot-assisted procedure were excluded from the cost analysis. Total medical costs were comparable after laparoscopic and open distal pancreatectomy (mean difference (si27 (95 per cent bias-corrected and accelerated confidence interval (sic)-4700 to 3613; P = 0.839). Laparoscopic distal pancreatectomy was shown to have a probability of at least 0.566 of being more cost-effective than the open approach at a willingness-to-pay threshold of (sic) per day of earlier recovery, and a probability of 0.676 per additional quality-adjusted life-year at a willingness-to-pay threshold of (sic) 80 000. There were no significant differences in cosmetic satisfaction scores (median 9 (i. q. r. 5.75-10) versus 7 (4-8.75); P = 0.056) and disease-specific quality of life after minimally invasive (laparoscopic and robot-assisted procedures) versus open distal pancreatectomy.

Conclusion: Laparoscopic distal pancreatectomy was at least as cost-effective as open distal pancreatectomy in terms of time to functional recovery and quality-adjusted life-years. Cosmesis and quality of life were similar in the two groups 1 year after surgery.
