The patients presented with abdominal pain, recurrent nonbilious vomiting, and growth retardation after a v ariable period of normal food intake. There was no history of peptic ulceration and corrosive ingestion. Barium meal showed dilated stomach with delayed gastric emptying. Exploration demonstrated dilated stomach with no intrinsic or extrins ic mechanical obstruction at the pylorus. Heineke-Mikulicz pyloroplasty was cur ative. Patients improved postoperatively and started thriving. We propose etiolo gy and the term pyloric achalasia for this late-onset functional gastric outlet obstruction.展开更多
