ABSTRACT
Both pylorus-preserving gastrectomy (PPG) and segmental gastrectomy (SG) achieve the preservation of gastric cardia and pylorus through the circumferential resection of stomach, while concepts and surgical procedures of these two operations are obviously different. In this sense, transectional gastrectomy includes both PPG and SG. PPG is one of the standard surgical procedure for early gastric cancer (EGC). The extent of lymph node dissection (No.1, 3, 4sb, 4d, 6, 7, 8a, 9) and the retention of infrapyloric vessels, hepatic and pyloric branch of vagal nerve has formed a consensus. Meanwhile, SG is regarded as an investigational treatment according to the Japanese gastric cancer treatment guidelines. It is still controversial and may generate an ethical risk in the clinical practice. This article distinguishes the difference in the concepts and surgical procedures between PPG and SG, assisting a comprehensive evaluation in further research.
