Why it's done

Endoscopic mucosal resection is a less invasive alternative to surgery for removing abnormal tissues from the lining of the digestive tract. Your doctor may recommend the procedure to remove certain early-stage cancers or precancerous growths.

Some of the conditions that EMR has been used to treat include:

  • Barrett's esophagus
  • Cancer of the small intestine (duodenum)
  • Colon polyps
  • Colorectal cancer
  • Esophageal cancer
  • Noncancerous growths of the uterus (leiomyomas)
  • Stomach (gastric) cancer

Endoscopic mucosal resection is usually performed by a specialist in digestive system disorders (gastroenterologist) who has expertise in the technique.
