Edited by Meinhard Classen. (Pp. 475; illustrated; \u00a315.) New York: W B Saunders, 1987. This volume is one in the Clinics and Gastroenterology series published by Saunders and consists of a number of chapters on specific topics related to developing areas in gastrointestinal endoscopy. The authors are from around the world, all being at the forefront of their field and writing well. Currently Saunders have divided this Clinics in Gastroenterology series into two with one volume aimed for North America and the other one for Europe. There are no doubt good commercial reasons for this unfortunate development and this volume illustrates well how important it is to have an international authorship of repute and not to become parochial in our view."}],"container-title":["Gut"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/gut.28.11.1548","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,12,13]],"date-time":"2025-12-13T18:11:14Z","timestamp":1765649474000},"score":1,"resource":{"primary":{"URL":"https:\/\/gut.bmj.com\/lookup\/doi\/10.1136\/gut.28.11.1548"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1987,11]]},"references-count":19,"journal-issue":{"issue":"11","published-online":{"date-parts":[[1987,11,1]]},"published-print":{"date-parts":[[1987,11]]}},"alternative-id":["10.1136\/gut.28.11.1548"],"URL":"https:\/\/doi.org\/10.1136\/gut.28.11.1548","relation":{},"ISSN":["0017-5749","1468-3288"],"issn-type":[{"type":"print","value":"0017-5749"},{"type":"electronic","value":"1468-3288"}],"subject":[],"published":{"date-parts":[[1987,11]]}}}
