Comparison of postoperative complications and long‐term oncological outcomes in minimally invasive versus open pancreatoduodenectomy for distal cholangiocarcinoma: A propensity score‐matched analysis

Background Pancreatoduodenectomy (PD) is the only curative therapy for distal cholangiocarcinoma (dCC). There has been no study to compare outcomes between minimally invasive pancreatoduodenectomy (MIPD) and open pancreatoduodenectomy (OPD) for dCC. The aim of the study is to compare the two operation types for dCC in terms of postoperative and oncologic outcomes. Methods Data from 426 patients who underwent MIPD (n = 91) or OPD (n = 335) for dCC from January 2012 to December 2019 at two tertiary hospitals were retrospectively reviewed. After 1:2 propensity score matching, postoperative and oncologic outcomes were compared. Results Minimally invasive pancreatoduodenectomy group showed more favorable results than OPD group in terms of blood loss (MIPD vs OPD, 250 [150‐400] vs 400 [200‐600], mL, P
