Rectal cancer treatment has advanced significantly over the past decades, with minimally invasive techniques providing patients with effective outcomes and quicker recovery. Transanal Minimally Invasive Surgery (TAMIS), also referred to as transanal surgery, has emerged as a leading option for early-stage rectal cancer and selected benign tumours. In this article, we explore what TAMIS involves, its benefits, and why consulting a specialist is crucial for determining the most appropriate treatment approach.

What is Transanal Minimally Invasive Surgery (TAMIS)?
TAMIS is a minimally invasive surgical technique performed through the anus to remove rectal tumours. Unlike traditional rectal surgery, which often requires abdominal incisions, TAMIS allows surgeons to access the rectum directly, reducing trauma to surrounding tissues. This approach is particularly effective for patients with early-stage rectal cancer, polyps, or certain benign tumours located in the mid to lower rectum.
The procedure is performed under general anaesthesia, using specialised instruments and a high-definition camera. This allows the surgeon to excise tumours with precision while preserving rectal function.
Benefits of TAMIS
Patients considering transanal surgery in Singapore often cite the following advantages:
- Minimally invasive: No abdominal incisions are required, which reduces post-operative pain and scarring.
- Shorter recovery time: Most patients can return home within one to two days, depending on individual health conditions.
- Preservation of bowel function: Unlike traditional surgery, TAMIS minimises disruption to surrounding muscles and nerves.
- Lower complication rates: With less tissue trauma, the risk of infection and post-operative complications is reduced.
- Effective for early-stage tumours: TAMIS is highly suitable for localised rectal cancers and precancerous growths.
Who is Suitable for TAMIS?
Not all patients are candidates for TAMIS. It is most effective for:
- Early-stage rectal cancers confined to the rectal wall.
- Benign polyps that cannot be removed via colonoscopy.
- Patients with mid to lower rectal tumours.
Patients with advanced rectal cancer, tumours that have spread beyond the rectal wall, or those with certain medical conditions may require alternative surgical approaches. A thorough evaluation by a colorectal specialist is essential.
How is TAMIS Performed?
The TAMIS procedure generally follows these steps:
- Preparation: Patients undergo pre-operative imaging and bowel preparation to ensure a clear surgical field.
- Anaesthesia: General anaesthesia is administered for patient comfort.
- Surgical Access: A specialised transanal port is inserted, providing access to the rectum.
- Tumour Removal: Surgeons excise the tumour using high-precision instruments while monitoring progress via a high-definition camera.
- Closure: The surgical site is closed, often with absorbable sutures, and the patient is monitored post-operatively.
Recovery and Aftercare
Recovery following TAMIS is typically quicker than traditional rectal surgery. Patients are encouraged to follow post-operative instructions provided by their surgeon, including dietary adjustments, wound care, and activity restrictions. Regular follow-up appointments are crucial to monitor healing and detect any recurrence.
Cost of TAMIS in Singapore
The cost of transanal surgery in Singapore may vary depending on the hospital, complexity of the procedure, and length of stay. Additional costs such as pre-operative imaging, anaesthesia, and post-operative care may apply. For insurance and Medisave coverage, patients are advised to consult their specialist and insurance provider.
Why Consult a Specialist?
Choosing the right specialist is critical for successful TAMIS surgery. Colorectal surgeons with experience in minimally invasive techniques can provide personalised recommendations based on tumour size, location, and patient health. Consulting a specialist early ensures the best possible outcome and helps patients understand all available treatment options.

FAQs About TAMIS
1. What is the recovery time for TAMIS?
Most patients can return home within one to two days and resume normal activities within one to two weeks, depending on individual recovery.
2. How should I prepare for TAMIS surgery?
Preparation involves bowel cleansing, fasting, and pre-operative imaging. Your specialist will provide detailed instructions.
3. Is TAMIS considered surgery?
Yes, TAMIS is a surgical procedure, but it is minimally invasive and involves no abdominal incisions.
4. Are there risks associated with TAMIS?
As with any surgery, there are risks including bleeding, infection, and rare complications related to bowel function. Experienced specialists minimise these risks.
5. How effective is TAMIS for rectal cancer?
TAMIS is highly effective for early-stage rectal cancer and selected benign tumours. Long-term outcomes depend on tumour type, size, and stage.
