This condition involves the appendix forming a constricting loop around the ileum, potentially leading to closed-loop obstruction and bowel ischemia. We report the case of a 57-year-old male from Ethiopia who presented with classical features of SBO, including abdominal pain, bilious vomiting, and failure to pass stool and flatus. Imaging was inconclusive, and an exploratory laparotomy revealed appendico-ileal knotting involving the terminal ileum. The bowel was viable, and a simple appendectomy was performed. The patient had an uneventful recovery and was discharged on postoperative Day 5. Histopathology confirmed acute appendicitis with mucocele. This case underscores the diagnostic challenge of this rare condition and emphasizes the need for early surgical intervention to avoid complications.<\/jats:p>","DOI":"10.1093\/jscr\/rjaf520","type":"journal-article","created":{"date-parts":[[2025,7,14]],"date-time":"2025-07-14T09:39:27Z","timestamp":1752485967000},"source":"Crossref","is-referenced-by-count":2,"title":["The knotted appendix: an unusual cause of bowel obstruction: a case report"],"prefix":"10.1093","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2664-9452","authenticated-orcid":false,"given":"Suleiman Ayalew","family":"Belay","sequence":"first","affiliation":[{"name":"School of Medicine, College of Medicine and Health Sciences, University of Gondar , Maraki Street, Gondar City, Central Gondar Zone, PO Box 196 Gondar ,","place":["Ethiopia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muluken Assefa","family":"Zemariam","sequence":"additional","affiliation":[{"name":"Department of Surgery, College of Medicine and Health Sciences, University of Gondar , Maraki Street, Gondar City, Central Gondar Zone, PO Box 196 Gondar ,","place":["Ethiopia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael A","family":"Negussie","sequence":"additional","affiliation":[{"name":"School of Medicine, College of Health Sciences, Addis Ababa University, Tikur Anbessa Specialized Hospital , Churchill Avenue, Lideta Sub-City, PO Box 5657 Addis Ababa ,","place":["Ethiopia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mesenbet Tsegaye","family":"Ferede","sequence":"additional","affiliation":[{"name":"Department of Surgery, College of Medicine and Health Sciences, University of Gondar , Maraki Street, Gondar City, Central Gondar Zone, PO Box 196 Gondar ,","place":["Ethiopia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yirgedu Getu","family":"Tadele","sequence":"additional","affiliation":[{"name":"Department of Surgery, College of Medicine and Health Sciences, University of Gondar , Maraki Street, Gondar City, Central Gondar Zone, PO Box 196 Gondar ,","place":["Ethiopia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yonas Admaw","family":"Tiruneh","sequence":"additional","affiliation":[{"name":"Department of Surgery, College of Medicine and Health Sciences, University of Gondar , Maraki Street, Gondar City, Central Gondar Zone, PO Box 196 Gondar ,","place":["Ethiopia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-5199-5072","authenticated-orcid":false,"given":"Hailemariam Yohannes","family":"Asefa","sequence":"additional","affiliation":[{"name":"School of Medicine, College of Medicine and Health Sciences, University of Gondar , Maraki Street, Gondar City, Central Gondar Zone, PO Box 196 Gondar ,","place":["Ethiopia"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2025,7,14]]},"reference":[{"key":"2025071405392295900_ref1","doi-asserted-by":"publisher","first-page":"170","DOI":"10.1016\/j.jamcollsurg.2006.04.020","article-title":"Small bowel obstruction: a population-based appraisal","volume":"203","author":"Foster","year":"2006","journal-title":"J Am Coll Surg"},{"key":"2025071405392295900_ref2","doi-asserted-by":"publisher","first-page":"B133","DOI":"10.1111\/j.1440-1673.2007.01813.x","article-title":"Appendiceal tie syndrome","volume":"51","author":"Menon","year":"2007","journal-title":"Australas Radiol"},{"key":"2025071405392295900_ref3","doi-asserted-by":"publisher","first-page":"660","DOI":"10.1097\/00000658-190107000-00070","article-title":"Acute intestinal obstruction following appendicitis.
