Intestinal intussusception is defined as the distal migration of one segment of the intestine into an immediately adjacent segment. It's a rare condition in adults (incidence of 1-5%). Appendicular intussusception is a rare disease with an incidence of 0.01%, being five times more frequent in men. It’s commonly associated with an underlying lesion of the intestinal wall, such as adhesions, lipomas, adenomas, inflammatory bowel disease, endometriosis, polyps, Meckel’s diverticulum or neoplasia. It clinically ranges from asymptomatic to chronic pain, nausea, intestinal obstruction, etc. McSwain’s classification refers to a categorization of appendiceal intussusception and is based on the region of the appendix that undergoes intussusception. Computed tomography (CT) and colonoscopy are the gold standard for diagnosis which remains to this day a difficult challenge. Treatment is surgical, with intestinal resection being the most common procedure.

The methodology of this work consisted of reviewing the clinical case, its chronology, as well as a literature review up to the present date.

This case reports a 55 year old female patient who was referred to a colo-rectal surgery consultation following the incidental finding of an appendicular intussusception during a screening colonoscopy for colorectal cancer. She subsequently underwent an elective Laparoscopic Caecum Ressection. The post-operative was uneventful. Histology revealed the presence of endometriosis as the cause of this intussusception.

The main objective of this work was to present and raise awareness to a rare disease that is still of difficult diagnosis; as well as to report the diagnostic and surgical measures undertaken.
