Core Tip

Core tip: Control of salivary flow during endoscopic examination is important. We focused on a mouthpiece designed for control of saliva in this study. First, we produced a new continuous suction mouthpiece (CSM). Then, we evaluated its usefulness for esophagogastroduodenoscopy (EGD). This study indicates that the CSM can reduce the extent of salivary flow during EGD. Moreover, it tended to reduce the frequencies of suction and choking episodes during EGD.
