This document provides guidelines for endoscopic tissue sampling procedures to diagnose digestive system pathology. It aims to make evidence-based recommendations on the appropriate indications and protocols for sampling the upper and lower gastrointestinal tracts as well as the hepatopancreatobiliary tract. The guidelines cover tissue sampling techniques for common conditions in these areas and are split into two parts, with the lower gastrointestinal tract covered separately in Part 2.
