Abstract
Sixteen appendiceal lesions, which consited of 10 postoperative appendiceal inverted stumps, 4 cecal deformities, one appendiceal Crohn's disease and one invaginated appendix, have been found endoscopically during resent six years. It seemed very important for exact diagnoses to ask patients their past histories of appendectomy before examination, because most lesions found at the ileo-cecal region were related with appendectomy. We experienced a few rare cases including invagination and Crohn's disease of the appendix. Although appendiceal lesions were not so commonly recognized endoscopically, colonoscope should be inserted up to the cecum and orf ice of the appendix should be confirmed to prevent overlooking the ileo-cecal lesions.
