Other related information

This retrospective multi-institutional study was conducted to evaluate the AL rates after laparoscopic LAR for rectal cancer at three institutions of Yokohama Clinical Oncology Group in Japan from September 2014 to December 2017. The study protocol was approved by the Ethical Advisory Committee of Yokohama City University Medical Center and the institutional review board of each participating hospital before the study was initiated. Patient data were collected from clinical report forms. Eligibility criteria were 1) rectal cancer located within 15 cm from anal verge with histologically proven adenocarcinoma or signet-ring cell carcinoma and 2) having undergone primary rectal cancer resection. The exclusion criteria were 1) multiple primary cancers, 2) a history of treatment for other pelvic malignancy, 3) open or robotic surgery cases, and 4) emergent cases.
The primary endpoint of this study was the rate of AL within 30 days after surgery. Secondary endpoints were operative time, blood loss, postoperative complications, reoperation within 30 days after surgery, length of hospital stays, oncological clearance, and the rate of changing the surgical plan.
