Anomalous mesenteric vessel-a rare etiology of intermittent partial small bowel obstruction.

We report a case of an 11-year with recurrent episodes of abdominal pain and vomiting. Diagnostic laparoscopy during a severe episode demonstrated an anomalous blood vessel incompletely encircling the bowel, leading to transient partial small bowel obstruction. This likely represents a remnant vessel from the omphalomesenteric duct. Recurrent abdominal pain and vomiting in the pediatric population requires careful history and physical exam, and a willingness to entertain unusual diagnoses.
