Risks

Risks of the endoscopic mucosal resection include:

  • Bleeding. This most common complication often can be detected and corrected during the procedure.
  • 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 is removed.
  • Narrowing of the esophagus. Removing certain esophagus lesions increases the risk of scarring that narrows the esophagus, which may lead to difficulty swallowing and require further treatment.

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

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