Transanal Endoscopic Microsurgery

Definition

A minimally invasive endoluminal surgical approach for local excision of rectal lesions that cannot be directly visualized using high-definition magnification. This technique offers the advantages of superior visualization of the lesion and greater access to proximal lesions, with lower margin positivity and specimen fragmentation and lower long-term recurrence rates over traditional transanal excision.
