A CASE OF ESD FOR MUCOSAL PROLAPSE SYNDROME WITH REPEATED BLEEDING AND SEVERE ANEMIA

Abstract

A 19-year-old man visited our hospital with palpitations and bloody stools. We performed CS, which revealed a polypoid lesion with papillary structures adjacent to the dentate line. The patient was diagnosed with mucosal prolapse syndrome (MPS). EGD and capsule endoscopy did not reveal the cause of bleeding; therefore, anemia was believed to have been caused by bleeding of MPS. ESD was performed, and his anemia improved after the procedure. A follow-up CS performed six months later showed no recurrence. ESD is considered a minimally invasive treatment to resect refractory MPS. This lesion also had characteristics of cap polyposis, such as hypoproteinemia, white spots, Helicobacter pylori infection, and crypt hyperplasia.
