It is my pleasure to introduce you to this new Atlas by Professor DEMLING and his colleagues on the very timely subjects colonoscopy, duodenoscopy and endoscopic cannu­ lation of the bile and pancreatic ducts. Professor DEMLING, unlike many others who carry his teaching and administra­ tive burdens, continues to be very personally involved in performing endoscopies. His clinic is one of the best organized and best equipped in the world. Professor DEM­ LING and his colleagues have been instrumental in introducing to the European continent these new techniques of duodeno­ scopy, colonoscopy and bile duct cannulation which were originally developed in Japan. They have added significant contributions of their own and now present to the reader a clear, concise, very well illustrated description of these methods. Dr. CLASSEN is one of the pioneers in endoscopic cannula­ tion. He has been kind enough to come to the United States and share his expertise with us at several Post Graduate Education programs. The students in these courses have been most enthusiastic about his presentations. Through this text he makes his extensive experience available to all endo­ scopists. The beginner at cannulation will find the illustrations of the various shapes the papilla may assume most helpful. I had the pleasure this summer of teaching a course in Brazil with Dr. FRUHMORGEN. Very few physicians have con­ centrated on colonoscopy to the extent that he has.
