Congenital mesocolic hernia-a case report.

Internal hernias are defined as protrusions of viscera through congenital or acquired aperture within the peritoneal cavity without an exit from the abdomen. The entity is broadly diversified with a wide variety of forms and severity of symptoms. A 10-day-old, full-term infant with poor feeding, bilious vomiting, and faecal retention for 3 days presented at our hospital. In the abdominal ultrasound, a whirl-pool sign was detected and laparotomy indicated. Intraoperatively, a malrotation of the small bowel with herniation of the jejunum into a mesocolic hernia was detected.
