BACKGROUND/AIMS: 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. METHODOLOGY: 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.
