Radiologically suspected gastric volvulus associated with non-hypertrophic pyloric stenosis and omphalomesenteric band-induced ileal volvulus with atresia in a neonate.

This report describes a term neonate with multiple gastrointestinal issues: non-hypertrophic pyloric stenosis (NHPS)-induced gastric volvulus (GV) and ileal volvulus with atresia due to an omphalomesenteric band. The patient presented with early non-bilious vomiting and abdominal distension. Radiological studies indicated GV, gastric outlet obstruction and ileal atresia. An exploratory laparotomy confirmed terminal ileal atresia with volvulus from the fibrous band and NHPS, but no GV was found during surgery. Treatment involved resecting the terminal ileum, ileocaecal valve and caecum, followed by an ileo-ascending colonic anastomosis and pyloroplasty. Recovery was satisfactory. This case highlights the importance of considering a broad differential diagnosis in neonatal intestinal obstruction and conducting a careful evaluation of radiological findings.
