title: [Surgical management of pyloric stenosis induced by gastrointestinal chemical burn in children].
abstract: OBJECTIVE
  To investigate the efficacy of surgical management for pyloric stenosis induced by gastrointestinal chemical burn in children.
  
  
  METHODS
  Clinical data of 11 children with pyloric stenosis induced by gastrointestinal chemical burn were analyzed retrospectively. After the failure of medicine, intervention of low balloon expansion and stent placement, they underwent pylorectomy and gastroduodenostomy. The body weight, height, serum albumin, hemoglobin, transferrin were compared between 1 day before and 3 months after operation.
  
  
  RESULTS
  There were 10 males and 1 female with a mean age of 4.5 years old. The main cause of serious pyloric stenosis was the wrong intake of hydrochloric acid. Lesions involved the esophagus and stomach in the early stage, and 4 weeks later, the lesion mainly involved the pylorus, which resulted in scarring pyloric stenosis and complete pyloric obstruction. Pylorectomy and gastroduodenostomy was successfully performed. The mean operative time was (134±26) min. The estimated blood loss was (5±2) ml. The postoperative length of stay was (10±3) d. There were no surgical complications. During the follow-up of 3 months, all the patients resumed regular diet. The height, body weight, and intelligence appeared to be normal. They showed significant improvement in weight, serum albumin, globulin, hemoglobin, transferrin at 3 months after the surgery(P<0.05). Six months after surgery, the anastomosis was shown to be nornal in barium follow through exam with no signs of stricture of ulcer.
  
  
  CONCLUSIONS
  Pylorectomy and gastroduodenostomy is an effective management for pyloric stenosis induced by gastrointestinal chemical burn in children, whose short-term efficacy is good.
