 note = {INTRODUCTION: Pylorus-preserving gastrectomy （PPG）, which had been developed in 1960s, has been reappraised for years and now accepted as a type of function-preserving compared with those of laparoscopy- ssisted distal gastrectomy （LADG）, which does not preserve the pylorus and involves resection of the suprapyloric lymph nodes.
METHODS: Ninety six patients diagnosed as having gastric cancer of cT1N0 underwent either LADG （n=66） or LAPPG （n=30）. The patient demographics and the early surgical outcomes were evaluated retrospectively. The quality of lymph node dissection in LAPPG was also assessed pathologically.
RESULTS: Among 96 patients preoperatively diagnosed as cT1, pT1 was 88 cases and pT2 in 8, 91.7 % of  diagnostic accuracy. There were no differences in patient demographics, operative time, blood loss, the number of dissected lymph nodes, postoperative morbidity and length of hospitalization. Pathologically, the number of dissected lymph nodes at No. 3, 4, 6 were equal between the two groups. Among our LADG cases, 35（ 53%） were lesions confined to the mucosa with a distance between the pylorus and the anal margin of the tumor <4 cm.
CONCLUSIONS: Our initial experience suggests that LAPPG can be performed with acceptable quality of lymph node dissection and early surgical outcome. Because LAPPG was thought to be applied for about a half of our LADG cases according to the new guideline, LAPPG is expected to be indicated for more cases with early gastric cancer as a function-preserving limited surgery., 弘前医学. 62, 2011, p.180-185},
