Abstract:
Achieving a high-quality total mesorectal excision (TME) resection specimen is a central tenet of curative rectal cancer management. However, operating at the caudal extremity of the pelvis is inherently challenging and a number of patient- and tumour-related factors may increase the risk of obtaining a poor TME specimen and positive resection margins. Transanal TME (TaTME) is an advanced surgical technique developed to overcome the limitations in pelvic exposure and instrumentation of transabdominal surgery. This up-to-date narrative review describes the evolution of TME surgery, the indications for TaTME, current published outcomes, its limitations and future developments.

Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
