Learn about the TEM Procedure 

TEM (Transanal Endoscopic Microsurgery) is an innovative new procedure that provides an alternative option for the removal of certain rectal polyps and early stage tumors. TEM is a minimally invasive technique for mid-rectal and upper rectal tumors. Previously, surgery to remove rectal tumors always required an abdominal incision.

Now with TEM, certain types of early-stage rectal cancers or benign rectal polyps may be removed using a minimally invasive procedure requiring no surgical incision. TEM is performed through the rectum with specially designed microsurgical instruments that can remove lesions high inside the rectum. These were previously accessible only with major abdominal surgery.

Our Colorectal Institute has the technology, training, and expertise to perform this procedure that may eliminate the need for major surgery for many patients.

Advantages of Transanal Endoscopic Microsurgery (TEM)

  • No abdominal incision
  • Less bleeding
  • Less risk of infection and complications
  • Less risk of bowel obstructions post-surgery
  • Shorter hospital stay
  • Faster recovery and return to normal activities

Colorectal Cancer is the third most common cancer in both men and women. The overall lifetime risk of developing colorectal cancer is about 1 in 20 (5%). The good news is that mortality rate from the disease has been dropping steadily for the past 20 years due to early detection and screenings. Treatment has also improved for colorectal cancer over the past several years and, as a result, there are now more than 1 million survivors of colorectal cancer in the US.
