Comparison of pancreaticoduodenectomy and bile duct resection for middle bile duct cancer: A multi-center collaborating study of Japan and Korea

Abstract

Background: It is currently unknown whether bile duct segmental resection (BDSR) is an acceptable method for localized middle bile duct cancer (mid-BDC) when R0 resection can be achieved. This study aimed to investigate the short- and long-term outcomes of mid-BDC patients treated with pancreaticoduodenectomy (PD) compared to those for BDSR. Methods: This was a retrospective, Japanese and Korean multi-center collaboration study based on patients' medical records. Results: A total of 663 patients, including 245 BDSR and 418 PD cases, were enrolled. The incidence of postoperative pancreatic fistula (3.3% vs 44.1%, P
