Diagnostic Usefulness of Different Types of Gastrointestinal Endoscopic Investigations.

Plain-language summary

The number of endoscopies performed varies greatly between different countries and does not reflect variations in disease incidents. The costs of unnecessary endoscopies are significant and with a better selection of which patients need to be examined with endoscopy, resources could be saved in healthcare, and a better triage would mean that malignancies and other more serious conditions do not have to wait. An example of unnecessary endoscopy is a colonoscopy in patients with irritable bowel syndrome or gastroscopy in patients with functional dyspepsia. The purpose of the project is, among other things: * What diagnostic benefit have gastroscopy, colonoscopy, capsule endoscopy and double balloon enteroscopy for different indications in different age groups? * What are the risks of this type of examination? * Can patients be better selected based on symptoms, psychometric data or laboratory findings to reduce the number of unnecessary examinations and prioritize those that should be scooped up first? * Can changed calling methods reduce the number of late cancellations and rebookings and missed patients?
