Transanal Endoscopic Microsurgery (TEM)
UCSF colorectal surgeons now offer a minimally invasive procedure called Transanal Endoscopic Microsurgery (TEM) for removal of rectal tumors and early stage rectal cancers. TEM is available only at a select group of instiutions nationwide. 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 which can remove lesions high inside the rectum. These were previously accessible only with major abdominal surgery.
Advantages of Transanal Endoscopic Microsurgery (TEM)
With TEM, the colorectal surgeon has a longer reach and better visibility into the rectum. With TEM paitents benefit from the following:
No abdominal incision
Less risk of infection and complications
Less risk of bowel obstructions post-surgery
Shorter hospital stay
Faster recovery and return to normal activities
