Laparoscopic partial cecum resection in appendix intussusception.

Appendix intussusception (AI) is a difficult disease to diagnose. Various features of the disease have been analyzed in a 35-year-old female patient who was admitted with abdominal pain and diagnosed with AI. The diagnosis was made with colonoscopy and abdominal computed tomography. Laparoscopic partial cecum resection was performed. The pathology examination revealed foci of endometriosis externa, which infiltrated the muscular layer of the appendix. AI should be kept in mind in the differential diagnosis of recurrent abdominal pain. Colonoscopy is an indispensable examination for the differential diagnosis. Laparoscopic partial cecum resection, preserving ileocecal valve, is an appropriate treatment approach in irreducible cases that are not suspected to be malignant.
