Small Bowel Volvulus with a Jejunal Trichobezoar.

Background: Small bowel volvulus caused by a jejunal trichobezoar is an extremely rare and life-threatening emergency in children. Case characteristics: An 8-year-old girl with abdominal pain and persistent bilious vomiting. Observation: The abdominal computed tomography scan showed a solitary intraluminal mass and a whirl sign, suggesting the small bowel volvulus. Emergency laparoscopic exploration revealed the rotated segment of small bowel loops by a jejunal trichobezoar. Outcome: Satisfactory recovery after surgery. Message: Trichobezoars should be considered in the differential diagnosis of abdominal pain and projectile vomiting in children.
