Abstract: Objective To discuss the effect of pylorus-preserving gastrectomy for early gastric cancer(EGC). Methods Between August 1995 and December 2005, 52 cases of EGC underwent pyloruspreserving gastrectomy(PPG) and 159 cases of EGC underwent distal gastrectomy(DG), Clinicopathlogic data and follow-up results of the two groups were analyzed retrospectively, and gastric emptying and gallbladder function of 15 cases PPG and 17 cases DG were compared at the same time.Results Compared with DG group, patients in PPG group maintain the body weight, gastric emptying and gallbladder function. There was no significant difference between PPG group (92. 3% ) and DG group (93.1% ) in overall 5-year survival rate ( P = 0. 881 ). The 5-year survival rate of the the PPG group with lymph node dissection was D1 100%, D1+α 92. 3%, D1+β 88.9%, D2 87. 5% respectively.Conclusions For early gastric cancer, the pylorus-preserving gastrectomy is effective for maintaining the postoperative function with similar long term survival as that of distal gastrectomy.
