Abstract

An inverted appendix is a rare condition that occurs congenitally or is the result of surgery or intussusception associated with diseases such as appendix tumors, mucocele, fecalith, or worms. An inverted appendix produces similar abdominal symptoms to acute appendicitis, that vary from non-specific to acute or chronic pain in the right lower abdomen. There are no reports of this condition in Korea that the authors are aware of. We report a case 31-year-old male who visited our hospital complaining of pain in the right lower abdomen. A barium enema showed a moving tubular filling defect. An inverted appendix that appeared as a polyp was dissected by colonoscopy. (Korean J Gastrointest Endosc 2006; 32:397⁣399)
