Surgeons use transanal endoscopic microsurgery (TEM) to remove non-cancerous polyps (growths) and some early-stage cancerous tumors in the rectum. It involves the use of an endoscope to access the anal canal. This procedure is also known as transanal endoscopic operations (TEO) or transanal minimally invasive surgery (TAMIS). The specialty-trained colorectal surgeons at UNC REX are expert providers of transanal endoscopic microsurgery in Raleigh.
Who is a Good Candidate for TEM Surgery?
Transanal endoscopic microsurgery may help certain patients avoid more extensive, open abdominal surgeries. Advances in techniques and equipment allow surgeons to remove growths with TEM that were previously thought to be only treatable with traditional surgical methods. However, not everyone is eligible for this minimally invasive colorectal surgery, so your provider will work with you to decide which approach is best for you.
Your Consultation
During your initial consultation, you’ll meet with the surgeon, who will listen carefully as you describe your symptoms. After a review of your patient’s medical history, the surgeon may order additional pre-operative tests to determine further details regarding the size and location of the growths.
The surgeon will also discuss the details of transanal endoscopic microsurgery and set a date for the procedure. You may be requested to do a pre-operative bowel cleanse the day before surgery.
How Does Transanal Endoscopic Microsurgery Work?
The colorectal surgeons at UNC REX use specialized, state-of-the-art equipment when performing transanal endoscopic microsurgery. The patient is under general anesthesia during the entire surgery.
An endoscope, a tool featuring an optical camera and light, is highly advanced and projects detailed images onto an external monitor. This allows the surgeon to perform incredibly precise removal of growths.
The doctor can accurately excise the growths and seal blood vessels using a TEM electric scalpel. If needed, sutures can be placed to repair the rectal wall.
What to Expect After Transanal Endoscopic Microsurgery
Patients are typically discharged within 24 hours following TEM and can resume regular eating habits. Adhering to a lighter schedule allows the body to rest during surgical recovery. Minor discomfort or a day or two of incontinence may occur, but these are temporary conditions.
Benefits of TEM
- Precise removal of rectal tumors and polyps
- Faster recovery time and less postoperative discomfort
- Minimal or no external scarring due to the transanal approach
- Preservation of rectal function and reduced need for more invasive surgery
How Much Does Transanal Endoscopic Microsurgery Cost?
The cost of a TEM procedure varies based on each patient’s surgical plan and various additional fees, including those for the operating facility and anesthesia. For patients with health insurance benefits, a portion of the procedure’s price may be covered as a medically necessary expense.

Frequently Asked Questions
How long does transanal endoscopic microsurgery take?
Most TEM procedures take 1-3 hours to complete, depending on the size, location, and complexity of the growth(s) being removed. The actual duration can vary based on whether additional repairs to the rectal wall are needed.
What does a pre-operative bowel cleanse involve?
A pre-operative bowel cleanse typically means drinking a prescribed laxative solution (such as polyethylene glycol or magnesium citrate) and following a clear liquid diet to empty the bowels before surgery. This process usually begins 24 hours before the procedure and may cause frequent bowel movements to ensure the surgical area is clean and provides optimal visualization during the operation.
Do I need to stop taking my regular medications before and after the procedure?
You should discuss all your current medications with your surgical team during your initial consultation, as some may need to be temporarily stopped or adjusted before or after TEM surgery. Certain prescriptions, such as blood thinners, diabetes medications, or supplements, may interfere with surgery or anesthesia, while others can be safely continued during the bowel preparation process.
Can TEM be repeated if growths return or new ones develop?
Yes, TEM can usually be performed multiple times if needed, as long as the patient remains a good candidate for the procedure. The minimally invasive nature of transanal endoscopic microsurgery makes repeat treatments more feasible than traditional open surgery.
