Colonoscopic diagnosis of appendiceal intussusception: case report and review of the literature

James E Duncan et al. JSLS. 2005 Oct-Dec.

Abstract

Intussusception of the appendix is an extremely rare condition. Although approximately 200 cases of appendiceal intussusception have been reported in the literature, very few have ever been diagnosed preoperatively. We report a case of appendiceal intussusception secondary to endometriosis in an otherwise healthy female. The case was diagnosed preoperatively by colonoscopy and treated surgically at laparoscopy. We review the literature of appendiceal intussusception and discuss the associated conditions, diagnosis, and a classification scheme for this unusual finding.
