Abstract

The primary objective in the treatment of early rectal cancer is to achieve optimal oncological control while minimizing the long-term impact of therapeutic interventions on patients' quality of life. The current standard of care for most stage I and II rectal cancers involves radical surgery, specifically total mesorectal excision. Although total mesorectal excision is generally curative for early rectal cancers, it can significantly affect patients' quality of life by potentially necessitating a permanent colostomy and causing bowel, bladder, and sexual dysfunction. Given the morbidity associated with radical surgery, alternative approaches to managing early rectal cancer, such as local excision through transanal excision, transanal endoscopic microsurgery, and transanal minimally invasive surgery, have been investigated. If these surgical approaches are applied cautiously to carefully selected cases of early rectal cancer, it is anticipated that these local procedures will achieve comparable oncological outcomes to the established standard of radical surgery, potentially offering superior results regarding morbidity, mortality, and overall quality of life.
