Asymptomatic intussusception secondary to a giant appendiceal mucocele treated via a laparoscopic approach

Laparoscopic appendectomy for appendiceal intussusception assisted by colonoscopy: A case report

“…Intussusception of the appendix may result from abnormal peristalsis [5] . The causes of appendiceal intussusception in the 11 cases identified in our literature search were as follows: endometriosis (three cases) [7] , [8] , [9] , lymphoma (two cases) [10] , [11] , adenoma (two cases) [12] , [13] , and hyperplasia [14] , mucocele [15] , torsion [16] and pregnancy (one case each) [17] . Appendiceal intussusception is diagnosed via ultrasonography, computed tomography, contrast enema, and colonoscopy.…”

Minimally invasive surgery for appendiceal intussusception caused by mucocele of the appendix: case report and review of the literature

“…Diagnosis is difficult before operation due to the variable presentation and unspecific symptoms of appendiceal intussusception. Some patient cases were accidentally identified during surgery (11). However, the preoperative diagnosis is very important for the selection of an adequate surgical method and could prevent intraoperative and postoperative complications.…”

Appendiceal Intussusception

“…Finally, in two asymptomatic patients, screening blood tests revealed an increased serum γ-glutamyltranspeptidase (γGTP) in the first and an elevated serum carcinoembryonic antigen (CEA) in the second one. Both patients suffered from appendiceal intussusception due to preexisting mucoceles (Lu et al, 2009;Okuda et al, 2008). In most cases of appendiceal intussusception, radiographical findings were normal, unless a small-bowel obstruction co-existed.…”
