Transanal Total Mesorectal Excision (taTME) in Glendale & Los Angeles
Transanal total mesorectal excision (taTME) is a technique for removing rectal cancer that combines a transanal approach (working from below, through the anus) with a traditional or minimally invasive abdominal approach. It can be particularly useful in a narrow pelvis or with low-lying tumors, where visualization and access from above alone can be difficult.
Treatment Approach
- Performed by a team working from both the abdominal and transanal sides
- Aims to achieve a complete, intact removal of the rectum and surrounding lymphatic tissue (the "mesorectum")
- Candidacy depends on tumor location, stage, and pelvic anatomy, determined through imaging and staging beforehand
A Note Worth Reading
taTME is one option among several surgical approaches to rectal cancer, and whether it’s appropriate depends on the specifics of the tumor and the patient’s anatomy — it is not the right approach for every rectal cancer case.

What happens at a first consultation?
A first visit typically includes a review of your symptoms and medical history, relevant prior test results (bring colonoscopy reports, imaging, or pathology if you have them), and a focused physical exam when appropriate. From there, the surgeon will explain what’s likely going on, what (if any) additional testing is needed, and the range of treatment options — from conservative management to procedures or surgery — so you can make an informed decision together.
