Transanal Minimally Invasive Surgery (TAMIS)

TAMIS (Transanal Minimally Invasive Surgery) is a new form of Transanal Endoscopic Microsurgery (TEM) pioneered in 2009 that allows surgeons to remove some rectal lesions without removing the entire rectum. TAMIS is a minimally invasive alternative that utilizes laparoscopic instruments through the anus to remove precancerous lesions and early rectal cancers without an abdominal incision.

Benefits of TAMIS

The largest benefit of TAMIS is in preserving the rectum and avoiding an abdominal incision. Previous surgical treatments for early stage rectal cancer or precancerous polyps involved major abdominal surgery to remove the portion of the rectum containing the lesion. TAMIS allows for removal of the lesion while preserving the rectum. Instead of spending days in the hospital and the major pain and risk of abdominal surgery, TAMIS allows patients to have outpatient surgery, minimal pain, and less risk of complications.

Who should consider TAMIS?

TAMIS is an alternative treatment for some people with early stage rectal cancer or precancerous polyps. Your colon cancer physician at the Swedish Colon and Rectal Clinic can help you determine if TAMIS is an appropriate treatment for you.

Why Choose Swedish

TAMIS is new technology, and is available at just a few institutions in Washington State. Swedish is the only hospital in Seattle that offers this rectum preserving treatment.
