Introduction Rectal malignant polyps can be managed by use of trans‐anal resections (TAR). Traditional techniques of resection have been replaced by use of platforms such as trans‐anal minimally invasive surgery (TAMIS) or trans‐anal endoscopic microsurgery (TEM). This study reviewed the management of rectal malignant polyps, in particular focussing on when clinicians used TAR. Methods A population wide cohort study of all malignant rectal polyps diagnosed in Queensland, Australia from 2011 to 2018 was undertaken. Patient and pathological factors were compared across the management strategies of polypectomy, TAR and rectal resection. Results Overall 430 patients were diagnosed with a malignant rectal polyp during the study period, with 103 undergoing a TAR. There was increasing use of TAR across the study period as a management strategy (P
