Questions were the indications for PPG, preservation of the vagus nerves and the infra\u2010pyloric artery, whether suprapyloric lymph nodes are dissected, distance between the pylorus and the gastrogastrostomy, and the advantages and disadvantages of PPG.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Responses were obtained from 345\u00a0institutions (37.1%). In 148\u00a0institutions, PPG was included in the choices of operations for gastric cancer and indicated for patients with tumors no deeper than the submucosal layer for differentiated\u2010type carcinoma, or for tumors limited to the mucosa even in poorly differentiated types in 105\u00a0institutions. The vagus was preserved in 73.5%, the infrapyloric artery was preserved in 49.4%, and the dissection of suprapyloric lymph nodes were partly performed in 56.2%. The distance between gastrogastrostomy and the pyloric ring was 3\u20133.9\u00a0cm in 43.4% and 2\u20132.9\u00a0cm in 39%. Layer\u2010to\u2010layer anastomosis was the most representative technique for gastrogastrostomy. The advantages of PPG with decreased incidence of dumping syndrome and remnant gastritis were quoted in 130 and 82\u00a0institutions, respectively. Delayed gastric emptying was considered as the most frequent disadvantage of PPG, as quoted by 111\u00a0institutions.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>These results indicate that standard technique in PPG includes the preservation of the vagus and infrapyloric artery, in part dissection of suprapyloric lymph nodes, and layer\u2010to\u2010layer anastomosis for reconstruction. The optimal length of the antral cuff is still controversial.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00268-012-1491-6","type":"journal-article","created":{"date-parts":[[2012,2,17]],"date-time":"2012-02-17T20:10:18Z","timestamp":1329509418000},"page":"858-863","source":"Crossref","is-referenced-by-count":22,"title":["Current
