Short- and Long-Term Outcomes of Open, Laparoscopic, and Robot-Assisted Surgery for Rectal Cancer.

ABSTRACT:

Background

Robot-assisted surgery has short-term benefits in rectal cancer surgery; however, its long-term advantages remain unclear. This study compared short- and long-term outcomes of open, laparoscopic, and robot-assisted rectal cancer surgeries using large-scale, database-driven evidence.

Methods

Patients (28 711) diagnosed with clinical stages I-III rectal cancer who underwent rectal resection and were registered in the Japanese Medical Data Vision Co. Ltd. database were included. Open rectal resection (ORR), laparoscopic rectal resection (LRR), and robot-assisted rectal resection (RARR) were identified. The primary outcomes were 5-year overall survival (OS) and relapse-free survival (RFS). Secondary outcomes included perioperative outcomes.
