Surgical outcomes of robotic, laparoscopic, and open low anterior resection after preoperative chemoradiotherapy for patients with advanced lower rectal cancer
Abstract Purpose We investigated the surgical outcomes of robotic low anterior resection (LAR) for lower rectal cancer after preoperative chemoradiotherapy (pCRT).Methods A total of 175 patients with lower rectal cancer who underwent LAR after pCRT between 2005 and 2020 were stratified into open (OS, n?=?65), laparoscopic (LS, n?=?64), and robotic surgery (RS, n?=?46) groups. We compared the clinical, surgical, and pathological results among the three groups.Results The RS and LS groups had less blood loss than the OS group (p?
