Robotic low anterior resection (RLAR) and transanal TME (TaTME) were developed to overcome the technical challenges of conventional open TME. This study aimed to compare the short- and long-term outcomes of RLAR versus TaTME for rectal cancer.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>Retrospective data from patients undergoing RLAR or TaTME at a colorectal unit in Singapore were analysed. The primary outcomes were the short-term clinical and pathological results including specimen margins and quality of TME. Secondary outcomes were recurrence, disease-free survival (DFS), and overall survival rates.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>A total of 80 patients who underwent either RLAR or TaTME were analysed. The TaTME group had a shorter operating time than the RLAR group (354 versus 481\u2009min respectively; P\u2009&amp;lt;\u20090.001) and fewer stays in the high-dependency and intensive care units (38.1 versus 73.7 per cent; P\u2009=\u20090.010). There was a higher rate of readmissions at 30\u2009days in the TaTME group (19.0 versus 0 per cent; P\u2009=\u20090.006). Specimens from TaTME had greater proximal (14.0 versus 10.0\u2009cm; P\u2009=\u20090.045) and distal (2.50 versus 1.65\u2009cm; P\u2009=\u20090.021) margins. Patients undergoing TaTME had borderline longer DFS (25.9 versus 15.7\u2009months; P\u2009=\u20090.049). Subgroup analysis of patients with (y)pT3\u20134 tumours showed fewer positive circumferential resection margins with TaTME (0 versus 18.2 per cent; P\u2009=\u20090.019) and improved DFS (25.9 versus
