Laparoscopic perigastric mesogastrium excision technique for radical total gastrectomy

摘要

IntroductionComplete mesogastrium excision (CME) of the perigastric mesogastrium and dissection of lymph nodes (LNs) no. 10 and no. 11 remain technically challenging aspects of laparoscopic radical total gastrectomy (LRTG) plus CME. To address some of these difficulties, we introduced the laparoscopic perigastric mesogastrium excision technique (LPMET) and the concept of the “enjoyable space” to partly modify the procedures of conventional radical surgery and characterize the perigastric space and the surgical plane as well as its boundaries.
