Diffusion of knowledge about Helicobacter pylori as assessed in an open-access endoscopy system: a prospective
Background/Aim:
Aim of the present study is to assess, according to the guidelines of the Maastricht Consensus Conference, the appropriateness and diagnostic yield of upper gastrointestinal endoscopy in an open-access endoscopy system, in order to evaluate the diffusion of knowledge about Helicobacter pylori among different types of physicians.
Methods:
Patients undergoing endoscopy because of dyspeptic symptoms were prospectively considered in 21 endoscopy services of Campania during two different 1-week periods in 1998 and 2001. The following data were recorded: age, sex, symptoms, history of peptic ulcer with regard to previous endoscopic or radiographic examinations and treatment, endoscopic diagnosis, and H. pylori status. The indication for endoscopy was evaluated according to Maastricht guidelines and current medical knowledge.
Results:
In the two periods, 1998 and 2001, 706 and 520 patients were, respectively, considered. The two series were matched for demographic characteristics, symptoms, and endoscopic diagnosis. Endoscopy was considered not indicated in 398 patients (56.4%) in 1998 and in 265 patients (50.9%) in 2001 (p = NS). The majority of them, 288/398 (72.3%) in 1998 and 162/265 (61.1%) in 2001 (p = 0.001), had recently undergone endoscopy or radiology and empiric antisecretory treatment or eradication. They had been referred to endoscopy because of recurrence of symptoms or to assess healing. In 110 cases in 1998 (27.6%) and in 103 cases in 2001 (38.9%; p = 0.001) endoscopy was performed in dyspeptic patients younger than 45 years without alarm symptoms.
Conclusions:
4 years after the Maastricht Conference, a large number of endoscopic examinations are not indicated and could be avoided following the Maastricht guidelines. In 2001, in comparison to 1998, a larger number of physicians are likely to investigate and treat correctly the H.-pylori-related diseases, but there are still some problems with the application of the 'test-and-treat policy'.
