Appendiceal band syndrome causing acute small bowel obstruction with concomitant appendicitis: a case report

Appendiceal band syndrome is a rare complication of acute appendicitis in which the appendix encircles a segment of small bowel, causing mechanical obstruction. Due to its rarity and nonspecific presentation, diagnosis is often made intraoperatively, and delayed recognition may lead to bowel strangulation. A 23-year-old male presented with acute abdominal pain, vomiting, distension, and obstipation, with no prior surgical history. Computed tomography showed dilated small bowel loops with a distal ileal transition point, an inflamed appendix, and mesenteric twisting. Emergency laparotomy confirmed small bowel obstruction due to an appendiceal band with acute appendicitis. Adhesiolysis and appendectomy were performed, leading to complete resolution. The postoperative course was uneventful. Appendiceal band syndrome should be considered in young patients with obstruction and no prior surgery. Early surgical intervention is essential for favorable outcomes.
