title: Length of the antral segment in pylorus-preserving gastrectomy.
abstract: BACKGROUND
  Pylorus-preserving gastrectomy (PPG) has the advantages of preventing dumping syndrome and duodenogastric reflux. However, time was required to reduce symptoms of gastric fullness or to improve food intake after surgery. The aim of this study was to investigate whether the length of the retained antral segment influenced the postoperative symptoms in patients who underwent PPG.
  
  
  METHODS
  Thirty patients with early gastric cancer who underwent PPG were divided into two groups according to the length of the retained antrum. In group 1 (n = 20) the transection was 1.5 cm and in group 2 (n = 10) it was 2.5 cm proximal to the oral edge of the pyloric ring. The subjects were interviewed and examined periodically to assess symptoms, food intake, body-weight and serum nutritional variables. Endoscopy and a radioisotope gastric emptying test were performed 1 year after the operation.
  
  
  RESULTS
  In group 1 gastric fullness after meals was common, resulting in poor food intake and poor recovery of body-weight. A high incidence of food residue in the remnant stomach was found in group 1. With regard to gastric emptying, seven of 20 patients in group 1 and one of ten in group 2 had a delayed emptying curve 1 year after operation.
  
  
  CONCLUSIONS
  Group 2 was superior to group 1 in terms of postprandial symptoms, food intake, recovery of body-weight and gastric emptying. The length of the retained antrum may play an important role in the motility of the pyloric ring following PPG.
