BackgroundAn 83-year-old lady was admitted with a 3-day history of non-specific abdominal pain that had rapidly increased in severity on the day of admission necessitating an emergency laparotomy. Intra-operative findings demonstrated a mechanical small bowel obstruction secondary to a chronically inflamed appendix acting as a tourniquet around a loop of terminal ileum.Learning PointThis case highlights an extremely rare and life-threatening complication of appendicitis.Literature ReviewTrue mechanical small bowel obstruction secondary to an acutely or chronically inflamed appendix encircling the distal small bowel remains extremely rare with only ten cases reported in the literature.ConclusionClinical assessment remains paramount in the treatment of these patients to facilitate prompt diagnosis and treatment which is vital to provide an optimal platform for post-operative recovery and survival. Although CT imaging is a highly effective investigative modality in these cases, operative treatment should not be delayed for a radiological investigation in the presence of abdominal peritonism.
