Comparison of outcomes between laparoscopic and open pancreaticoduodenectomy without radical lymphadenectomy: Results of coarsened exact matching analysis using national database systems

Laparoscopic pancreaticoduodenectomy has recently been covered under Japan's insurance system for patients not requiring lymph node dissection. Only high‐volume hospitals that meet specific criteria are permitted to perform laparoscopic pancreaticoduodenectomy. Although open and laparoscopic pancreaticoduodenectomy outcomes with lymph node dissection have been described previously, procedures performed without lymph node dissection have not been compared using a nationwide database. This study aimed to review the results of laparoscopic pancreaticoduodenectomy and compare them to those of open pancreaticoduodenectomy (OPD) using records from a nationwide database.
