Appendiceal Intussusception Masquerading as an Ileocolic Intussusception

Abstract

Classification of appendiceal intussusception (type I-V) is based on the level of appendiceal invagination. Appendectomy is the treatment of choice unless there is a concern for a neoplasm in which case a more extensive resection may be necessary. We report a 47-year-old with an appendiceal intussusception.

Manual laparoscopy-assisted intraoperative reduction for adult ileocolic intussusception with ileal adenoma: A case report

“…The patient described by Yamaguchi et al underwent ileocecal resection for an Appendix tumor, whereas the latter patient avoided intestinal resection. Six cases of attempted intraoperative reduction were found among twenty-two case reports; two patients underwent complete reduction, two patients underwent partial reduction and the remaining two cases were not successfully treated (Table 1) [4], [9], [10], [11], [12], [13]. The patients who underwent complete or partial reduction avoided extensive or invasive resection.…”

Adult Appendix Cecal Intussusception by Lymphoid Hyperplasia - A Rare Diagnosis

“…In the setting of a neoplasm, more extensive resection may need to be undertaken such as an ileocecectomy or right hemicolectomy [7]. There is an appendiceal inside the appendix.…”

Intussusception of the Appendix and Ileum Endometriosis: A Case Report

“…Appendiceal intussusception may lessen spontaneously [7,16]. The intussusception of the appendix may lessen during colonoscopy, when air is insufflated [17], or there may even be a total reduction of it [4].…”

“…The intussuscepted appendix may be reduced with a barium enema or air enema. Appendectomy is the treatment of choice in both children and adults [16,22]. It can be carried out by means of a laparotomy or laparoscopically [4].…”

“…Some authors suggest performing an exploratory laparotomy if there is any suspicion of appendiceal mass, cecal neoplasm, or compound ileocecal-appendiceal intussusception [4]. In some situations, ileocecal resection and partial cecectomy could be performed; e.g., if there is concern for a neoplasm, then an ileocecectomy or right hemicolectomy may be necessary [16]. Right hemicolectomy with lymph node resection should be done when the diameter of the tumor is larger than 2 cm or when malignancy is suspected [4].…”
