McSwain type V appendix intussusception

Abstract

[Excerpt] Intestinal intussusception consists of distal migration of a segment from the intestine to the adjacent intestinal lumen. Appendicular intussusception (AI) is a rare disease that constitutes a clinical challenge. The incidence of AI is estimated at 0.01%.1 It is five times more frequent in men.2 Despite imaging and endoscopic advances, diagnosis remains a difficult challenge. The presentation of AI varies from asymptomatic to chronic pain.3 This case reports a 33-year-old woman with past gastro-oesophageal surgery and complementary appendectomy, which was evaluated for the chronic pain in the right lower quadrant. Colonoscopy (figure 1A,B) revealed intussusception of appendix type V. A laparoscopic caecum resection was performed. The postoperative was uneventful. Histology revealed AI with lumen obliteration by foreign body (suture of previous intervention). [...]
