A propensity score-matching analysis comparing the oncological outcomes of laparoscopic and open surgery in patients with Stage I/II colon and upper rectal cancers

摘要

Purpose Previous studies from Western countries have shown similar survival outcomes after both open and laparoscopic resections. In Japan, radical D3 dissections performed by open resection have been routinely performed for ≥T2- or ≥N1-stage cancers, and relatively favorable survival outcomes were obtained. This study compared the survival in patients with Stage I/II colon and upper rectal cancers undergoing laparoscopic and open resection.
