Button gastrostomy obstructing the ileocecal valve removed by colonoscopic retrieval.

A 16-year-old male with profound developmental disability acutely developed retching, irritability, and abdominal distension. He had undergone a fundoplication and placement of a feeding gastrostomy 6 months earlier. A button gastrostomy tube was subsequently placed, but was noted to be missing from the stoma when the patient was awakened by his mother one morning. Within 48 hours he developed signs of abdominal obstruction. Abdominal radiography confirmed the presence of the gastrostomy button at the ileocecal valve. After a trial of decompression and medical management failed, the button was successfully removed endoscopically, resulting in prompt resolution of the obstruction. Gastrostomy buttons are a newer alternative to conventional catheters, but can become dislodged and migrate, as illustrated by this case. Refinements in the outer wing design may be needed.
