Objective:To describe an adolescent with pathologic aerophagia, a rare condition caused by
excessive and inappropriate swallowing of air and to review its treatment and
differential diagnoses.Case description:An 11-year-old mentally impaired blind girl presenting serious behavior problems
and severe developmental delay with abdominal distension from the last 8 months.
Her past history included a Nissen fundoplication. Abdominal CT and abdominal
radiographs showed diffuse gas distension of the small bowel and colon.
Hirschsprung's disease was excluded. The distention was minimal at the moment the
child awoke and maximal at evening, and persisted after control of constipation.
Audible repetitive and frequent movements of air swallowing were observed. The
diagnosis of pathologic aerophagia associated to obsessive-compulsive disorder and
developmental delay was made, but pharmacological treatment was unsuccessful. The
patient was submitted to an endoscopic gastrostomy, permanently opened and
elevated relative to the stomach. The distention was resolved, while maintaining
oral nutrition.Comments:Pathologic aerophagia is a rare self-limiting condition in normal children exposed
to high levels of stress and may be a persisting problem in children with
psychiatric or neurologic disease. In this last group, the disease may cause
serious complications. Pharmacological and behavioral treatments are ill-defined.
Severe cases may demand surgical strategies, mainly decompressive gastrostomy.
