摘要

In recent years, water jet instruments have been usedin the field of gastrointestinal endoscopy, mainly intwo clinical situations Investigation and treatmentunder endoscopic view. Injecting water jet into thegastrointestinal lumen is helpful for maintaining a clearendoscopic view, washing away blood or mucous in thelumen or on the surface of the tip of the endoscope.This contributes to reducing time and discomfort ofexamination. Water jet technology is an alternativemethod for dissecting soft tissue; this method doesnot harm the small vessels or cause mechanical orthermal damage. However, its use in clinical settingshas been limited to the transmucosal injection of waterinto the submucosal layer that elevates the mucosa toprepare for endoscopic mucosal resection or endoscopicsubmucosal dissection, instead of tissue dissection,which may occur because of the continuous waterjet. A preclinical study has been conducted using apulsed water jet system as an alternative method forsubmucosal dissection by reducing intraoperative waterconsumption and maintenance of dissection capability.This review introduces recent studies pertaining to usinga water jet in gastrointestinal endoscopy and discussesfuture prospects.
