Assessing the safety and outcomes of repeat transanal endoscopic microsurgery

Background Transanal endoscopic microsurgery (TEM) is the treatment of choice for benign rectal tumors and select early rectal cancers. This surgical approach has become ubiquitous and surgeons are seeing recurrent lesions after TEM resection. This study aims to outline the safety and outcomes of repeat TEM when compared to primary TEM procedures.
