Seromuscular laceration of the stomach associated with infantile hypertrophic pyloric stenosis in the newborn.

Two cases of seromuscular laceration of the stomach associated with infantile hypertrophic pyloric stenosis are reported. The diagnosis and treatment of this lesion is uncertain due to a paucity of clinical experience. The first patient was treated by mucosal resection. Early decompression therapy of the stomach is essential for the neonate with upper gastrointestinal obstruction or stenosis.
