Core Tip
Core tip: The present review discusses the role of pronase in increasing image quality during endoscopy. Premedication with pronase 10 to 20 min before endoscopy significantly improves mucosal visibility without affecting the accuracy of Helicobacter pylori identification. The effects of pronase as premedication are also applicable in advanced endoscopic procedures such as narrow-band imaging, magnifying endoscopy, or endoscopic ultrasonography. Although improved mucosal visibility does not necessarily improve clinical outcomes, premedication with pronase may be helpful for increasing the detection rate of early cancers.
