Gastroenterology has developed rapidly as a scientific and clinical discipline. Advances have resulted from simple, painstaking clinical observations on one hand and highly sophisticated scientific methods on the other. Some of the important developments in gastroenterology are reviewed here.
Topics were selected after formal discussion with colleagues, and priority was given to areas of current interest. Reference material was chosen after a literature search in the medical library and included abstracts from proceedings of recent conferences. Attendance at conferences allowed discussions with some experts; communication in writing was made with others.
