title: Postoperative evaluation of pylorus-preserving gastrectomy for early gastric cancer.
abstract: OBJECTIVE
  There have been many reports proposing some advantages of pylorus-preserving gastrectomy for gastric ulcer compared to the conventional distal gastrectomy. However, it is not clear whether similar results will be obtained from the patients with early gastric cancer.
  
  
  METHODS
  Of 50 patients with early gastric cancer, 25 underwent pylorus-preserving gastrectomy under strict criteria and the other 25 underwent distal gastrectomy with Billroth I anastomosis by the same surgeon. The subjects were then interviewed and examined periodically to assess symptoms, food intake, body weight and serum nutritional parameters. Endoscopy and a radioisotope gastric emptying test was performed 1 year after the operation.
  
  
  RESULTS
  Many of the patients with pylorus-preserving gastrectomy complained of gastric fullness after meals, resulting in poor food intake; a significant between-group difference was found up to 1 year after the operation. A low incidence of reflux gastritis and slow gastric emptying were confirmed in the patients after pylorus-preserving gastrectomy.
  
  
  CONCLUSIONS
  Pylorus-preserving gastrectomy has advantages over distal gastrectomy in terms of the avoidance of dumping syndrome and protection against duodeno-gastric reflux. However, more time was necessary for improved gastric fullness or food intake. Pylorus-preserving gastrectomy should be applied in younger patients with early gastric cancer expecting long survival.
