Abstract

© 2020 Elsevier Inc.Background: There has been increasing uptake of minimally invasive pancreatoduodenectomy during the past decade, but it remains a highly specialized procedure as benefits over open pancreatoduodenectomy remain contentious. This study aimed to evaluate current evidence on minimally invasive pancreatoduodenectomy versus open pancreatoduodenectomy in terms of impact of center volume on outcomes. Methods: A systematic review of articles on comparative cohort and registry studies on minimally invasive pancreatoduodenectomy versus open pancreatoduodenectomy published until 31st December 2019 were identified, and meta-analyses were performed. Primary endpoints were International Study Group on Pancreatic Fistula grade B/C postoperative pancreatic fistula and 30-day mortality. Results: After screening 7,390 studies, 43 comparative cohort studies (8,755 patients) with moderate methodological quality and 3 original registry studies (43,735 patients) were included. For the cohort studies, the median annual hospital minimally invasive pancreatoduodenectomy volume was 10. No significant differences were found in grade B/C postoperative pancreatic fistula (odds ratio: 0.98, 95% confidence interval: 0.78–1.23) or 30-day mortality (odds ratio: 1.14, 95% confidence interval: 0.65–2.01) between minimally invasive pancreatoduodenectomy when compared with open. No publication biases were present and meta-regression identified no confounding for grade B/C postoperative pancreatic fistula, center volume or 30-day mortality. Minimally invasive pancreatoduodenectomy was only strongly associated with significantly lower rates of postoperative pulmonary complications and surgical site infection, shorter length of stay, and significantly higher rates of R0 margin resections. Conclusion: Minimally invasive pancreatoduodenectomy remains noninferior to open pancreatoduodenectomy for grade B/C postoperative pancreatic fistula but is strongly associated with significantly lower rates of postoperative pulmonary complications and surgical site infection. Minimally invasive pancreatoduodenectomy can be adopted safely with good outcomes irrespective of annual center resection volume.
