Transanal excision of anorectal lesions.

TL;DRAbstract

Transanal excision of anorectal lesions is an attractive option for dealing with benign as well as malignant lesions of the anorectum. Benign lesions of the anorectum are best treated by local excision. Following transanal excision of rectal villous adenomas, recurrence rates range from 8% to 40% with most studies reporting a recurrence rate of around 20%. Because of the ability to perform more precise dissections TEM confers a lower recurrence rate of less than 10%. Radical resection with or without neoadjuvant or adjuvant therapy remains the most effective proven treatment for carcinoma rectum. With advances in surgical technique and the incorporation of a multi modality approach, sphincter preservation rates have improved but an abdominal operation is always associated with certain morbidity and mortality. In contrast local excision is associated with minimal morbidity and mortality and it preserves bowel continuity and avoids complications of radical excision like bowel, bladder an
