Gastric volvulus--a late complication of gastrostomy.

Two cases of gastric volvulus are reviewed. Both patients were nonverbal, mentally handicapped children, who were fed through a gastrostomy. They had intermittent intolerance to bolus feeds through the gastrostomy, accompanied by abdominal distension and vomiting of gastric contents. One had a previous partial fundoplication and gastrostomy, and the other had had two pyloroplasties and gastrostomy. The axis of torsion ran from the esophagogastric junction to the gastrostomy site. Both children were treated by detorsion and gastropexy. It is postulated that the gastrostomy served as a fixed point for the volvulus. This was facilitated by the chronically dilated stomachs induced by bolus feeds. These two cases are reported to alert the clinician to this possibility when a neurologically impaired child with a gastrostomy presents with feeding difficulties and persistent vomiting.
