Background: Sigmoid volvulus is a gastrointestinal condition and a medical
emergency that occurs when a segment of the colon twists upon its mesentery,
leading to bowel obstruction and gangrene of the intestine. Male patients and
seniors with persistent constipation are the primary populations affected by this
condition. We present a rare case of a gangrene sigmoid volvulus diagnosed
timely by CT-Scan. Case presentation: A 72-year-old Vietnamese male with a 3-day
history of abdominal pain presented at the emergency department. A thorough
medical history and physical examination revealed signs of bowel obstruction
without evidence of peritonitis. Computed CT confirmed the diagnosis of
sigmoid volvulus; it also led the surgical team to the decision to conduct an
emergency laparotomy surgery due to the sigmoid ischemic sign depicted on the
CT scan. Conclusion: This case report emphasizes the importance of radiographic
tests in diagnosing and treating bowel obstruction. Especially in suspicion of
volvulus, even without signs of peritonitis.
