✦ ADVANCED RECTAL LESION SURGERY

Transanal Excision / TAMIS / TEM

Q: Why is TAMIS / TEM done instead of regular colonoscopic polypectomy?

TAMIS / TEM is used for larger rectal polyps, sessile polyps, lesions with broad bases, or select early rectal cancers that cannot be safely removed during regular colonoscopy. They allow precise full-thickness excision with clean margins.

Q: Is this suitable for all rectal cancers?

Only for select early rectal cancers (T1) without high-risk features. More advanced rectal cancers usually need formal abdominal surgery (rectal resection) and other treatments. Detailed pre-operative staging is essential.

Q: Will I have a normal bowel habit after surgery?

Yes. Since the sphincter and most of the rectum are preserved, bowel habits return to normal within a few weeks. Some patients may experience mild urgency initially, which usually settles.

Q: Will I need follow-up?

Yes. Regular follow-up with examination, colonoscopy, and imaging when needed is essential to detect any recurrence or new lesions early.

What is Transanal Excision / TAMIS / TEM?

Transanal Excision, TAMIS (Trans-Anal Minimally Invasive Surgery) and TEM (Trans-Anal Endoscopic Microsurgery) are advanced surgical techniques to remove larger rectal polyps and select early rectal cancers entirely through the anus, without any abdominal incisions. Specialised platforms and laparoscopic-style instruments allow precise full-thickness excision of rectal lesions while preserving the sphincter and the rest of the rectum. As an experienced proctologist in Hyderabad, Dr. Tejasree Vengala performs transanal excision techniques at Lux Hospitals, Hyderabad, particularly valuable for select early rectal cancers in the lower and middle rectum.

Suitable for large benign rectal polyps not removable at colonoscopy, select early-stage rectal cancers (T1) without high-risk features, and patients wanting to avoid abdominal surgery and stoma when possible.

How the Procedure Works

Anaesthesia & Positioning

Surgery is performed under general anaesthesia. The patient is positioned in lithotomy or prone position depending on lesion location.

Trans-Anal Platform Insertion

A specialised TAMIS or TEM platform is inserted through the anus, allowing precise visualisation and instrumentation deep inside the rectum.

Lesion Marking & Excision

The lesion is carefully marked with a margin, and full-thickness excision is performed using laparoscopic-style instruments.

Defect Closure

The rectal wall defect is closed transversely with absorbable sutures to maintain proper rectal lumen.

Recovery & Discharge

Patients are discharged in 1–2 days with structured dietary advice and follow-up plan based on biopsy results.
