Small bowel obstruction caused by a fibrotic bow-string appendix: a consequence of non-operative management of acute...

A 73-year-old woman presented with small bowel obstruction that failed to settle with conservative management. Over the previous 2 years she had presented twice with computed tomography scan-proven acute appendicitis with localised perforation of the appendix tip. In view of medical comorbidities, she was treated non-operatively with clinical and radiological resolution on each occasion, but on the third presentation laparoscopy was undertaken for non-resolving small bowel obstruction and the non-inflamed appendix itself was identified as a fibrous band causing compression of the distal ileum and complete small bowel obstruction. Following division and appendicectomy, the patient made an uneventful recovery. This case illustrates the potential consequence of repeated appendiceal inflammation and non-operative management and may be seen increasingly as this approach is widely adopted during the COVID-19 pandemic.
