The European Association for Endoscopic Surgery (E.A.E.S.) has performed six consensus development conferences (CDCs) to address the key topics in the field of endoscopic surgery. This book contains: - the original recommendations as they were developed by groups of highly respected experts for each topic,- comments on these original statements to incorporate the latest knowledge, and- a description, a critical appraisal, and some ideas for the improvement on the way by which these recommendations were developed and disseminated.The book should serve all surgeons interested in endoscopic surgery as a principal guide, as it defines all important "Dos" and "Don'ts" on the basis of the available scientific evidence.
