title: The new look into the gastrointestinal tract.
abstract: Esophagogastroduodenoscopy has proved to be the most accurate method of diagnosing disese of the upper gastrointestinal tract. Endoscopic technics already are being employed for the treatment of gastric polyps. Experimental work on endoscopic treatment of upper gastrointestinal bleeding is under way in several medical centers. A variety of methods are being tested: laser photocoagulation, suture clip placement and the use of bioco+mpatible tissue glues. Endoscopic retrograde cholangiopancreatography now is established as a useful technic in the diagnosis of biliary tract disease. Its diagnostic usefulness in the pancreas is confined to certain diseases in which it is desirable to determine the need for operative intervention. The initial success of endoscopic papillotomy and stone extraction promises further future therapeutic uses for ERCP. Colonoscopy may well prove to be the most useful of the gastrointestinal endoscopic methods. It is particularly helpful in diagnosing colonic cancer, in determining the source of occult colonic bleeding and in providing information regarding idiopathic colonic inflammatory disease. The success of polypectomy indicates the possibility of substituting endoscopic treatment for invasive surgery. Laparoscopy in conscious patients is a well-established technic that is useful in gastroenterology, hepatology, oncology and gynecology. Its usefulness has long been appreciated in other countries and the method merits wide use in the United States. Endoscopy is a rapidly changing and evolving field. This monograph has attempted to outline the current state of the art, but many changes are expected in the next 5-10 years.
