ABSTRACT
There are diverse ring-like narrowings in the lower esophagus: mucosal ring, muscular ring, ring-like annular peptic stricture. Esophageal muscular ring is extremely rare and generally asymptomatic. It occurs at the proximal border of the esophageal vestibule that corresponds to the upper end of the lower esophageal sphincter. We experienced a case of lower esophageal muscular ring with a symptom of intermittent mild dysphagia for 40 years and report the findings with a review of the literature.

Colonic polyp is one of the most common lesions during colonoscopy, but appendiceal polyp is very rare. Moreover appendiceal intussusception associated with appendiceal polyp is extremly rare. Most appendiceal polyp is rarely diagnosed preoperatively, and diagnosed by postoperative pathologic specimen. We report a case of a 52-year old woman with appendiceal intussusception induced by appendiceal adenoma. She experienced sustained right lower quadrant pain for one month. Double contrast barium enema showed a mass in the cecal base without normal appendiceal filling and colonoscopy showed intussuscepted appendix with polyp on the tip. Endoscopic polypectomy with endoloop and snare was performed successfully without any complication.
