Tests and Procedures

Endoscopic mucosal resection

Risks

Risks of the endoscopic mucosal resection include:

  • Bleeding. This most common complication often can be detected and corrected during the procedure.
  • Narrowing of the esophagus. Removing a lesion that encircles the esophagus carries some risk of scarring that narrows the esophagus, a condition that may lead to difficulty swallowing and require further treatment.
  • Puncture (perforation). There is a slight risk of a puncture through the wall of the digestive tract, depending on the size and location of the lesion that's removed.

Call your doctor or get emergency care if you develop any of the following signs or symptoms after undergoing endoscopic mucosal resection:

  • Fever
  • Chills
  • Vomiting
  • Black stool
  • Bright red blood in the stool
  • Chest or abdominal pain
  • Shortness of breath
  • Fainting
