Transanal Endoscopic Microsurgery (TEM)

Transanal Endoscopic Microsurgery, or TEM, is a special type of minimally invasive surgery for rectal conditions. It extends the reach of the physician into the affected area through the anus, instead of through a surgical incision.

Transanal Endoscopic Microsurgery (TEM) at UMass Memorial Medical Center

UMass Memorial Medical Center is among only a handful of hospitals in New England and fewer than 100 in the country performing TEM, an innovative alternative to major surgery.

TEM is frequently used for the treatment of rectal polyps or early stages of cancers when the lymph nodes haven't been affected.

Advantages of Transanal Endoscopic Microsurgery (TEM)

TEM gives the surgeon a longer reach and enhanced visibility into the entire rectum. This ensures:

• No incisions/no surgical pain
• Less risk of infection and complications
• Less risk of nerve injury
• Less bleeding
• Shorter hospital stays
• Faster recovery
• Less risk of bowel obstructions after surgery
• Quicker return to normal activities

What Happens During Transanal Endoscopic Microsurgery (TEM)?

The TEM procedure typically takes two to three hours, with general anesthesia. During the procedure:

• Specialized instruments aid in the insertion of a tiny scope into the rectum.
• This scope allows the physician to reach and see much farther into the rectum than with other techniques and remove rectal polyps with more precision -- and without major surgery.
