Primary Small Bowel Volvulus: An Unusual Cause of Small Bowel Obstruction

We present the case of a 78-year-old female who presented to the emergency department with small bowel obstruction in a virgin abdomen. Although the patient did not have peritonism and biochemical investigations did not reveal alarming features of ischemia, an abdominal computed tomography (CT) scan was suggestive of small bowel volvulus (SBV), and operative exploration was pursued. No obvious cause was identified aside from hard stools throughout the colon and a diagnosis of primary SBV was determined. She was subsequently discharged symptom-free on day seven post-operatively. She re-presented on day 10 post-operatively with a similar history, examination, and abdominal CT findings suggestive of SBV recurrence. Her volvulus slowly resolved post administration of rectal enemas and did not require any further operative intervention; she was discharged on day eight of re-admission (day 19 post-operatively) with no recurrence of her symptoms on a regular diet. In this article, we discuss the management of SBV.
