title: Laparoscopic distal gastrectomy for pyloric stenosis caused by heterotopic glands in a young female: report of a case.
abstract: A 17-year-old female was referred to our hospital with worsening dietary intake and abdominal bloating. She had epigastric fullness, but no abdominal pain. Gastrointestinal endoscopy revealed food residue and pyloric stenosis. A contrast-enhanced radiograph also showed pyloric stenosis, and gastrografin was not passed well through her pylorus. Computed tomography revealed similar findings. The biopsy results indicated hyperplasia of the gastric glands. The patient was diagnosed with a benign lesion, and underwent endoscopic balloon dilation several times. However, her stenosis worsened and we decided to perform surgery. In consideration of the cosmetic outcome, we performed laparoscopic distal gastrectomy. The postoperative course was good, and the patient was discharged on postoperative day 10. The final diagnosis was pyloric stenosis caused by heterotopic glands. No malignant lesions were found. Since gastric stenosis caused by heterotopic glands has not been reported previously, we consider this to be a very rare case.
