title: Oxides, onions, and other matters gastrointestinal--1996--a perspective.
abstract: A selection of landmark articles for a given year in any subject risks being somewhat subjective, and subjectivity is best avoided in scientific endeavor. However, the very nature of such a selection process invites judgment. Like most judges, I, too, claim to avoid conscious bias, but no one who has ever graced the bench can claim that at the subconscious level personal bias has never crept into a decision. Similarly, deep down in the vault of my subconscious, I love a maverick. That perhaps explains why so many articles that challenge long-held beliefs have especially found favor. Among them are those that question the strength of the association of Helicobacter pylori with gastric cancer, the usefulness of surveillance endoscopy in patients with Barrett's esophagus, a randomized trial that casts doubt on the preeminence of laparoscopic cholecystectomy, and a metaanalysis that concludes that corticosteroids may not be nearly as good for alcoholic hepatitis as we were once told. I have tried to resist the temptation to be too laudatory of technologic advancement, unless the benefit to the patient of such technology has been defined clearly. Thus, of all of the new technologies (endoscopic retrograde choledochopancreatography is no longer a new technology), only endoscopic ultrasonography finds a place. Articles that assess preventive strategies and are in the realm of epidemiology have received mention. All in all, 1996 was not a spectacular year for major therapeutic advances. In contrast, some notable advances have been made in the laboratory, and perhaps the most important has to do with the role of nitric oxide both in the regulation of normal function and in the genesis of disease.
