Abstract:
An improved tool for endoscopic disruption of lower esophageal ring generally comprises scissors adapted to be inserted into a patient's esophagastric junction through a flexible endoscope. The scissors pair comprises a blunt tipped instrument having a pair of short cutting edges operable through an axially disposed cable or the like. In practice, the instrument is inserted into a flexible endoscope and thereby orally inserted into the patient's lower esophagus. Once inserted into the lower esophagus, the instrument is utilized to precisely sever a lower esophageal ring at a plurality of radial locations. Once effectively disrupted, any associated shelf effect will generally self-correct. Other procedures, such as hiatal hernia repair, may then be completed, whereafter the endoscope may be removed from the patient. The procedure should require only about 20 minutes to complete and will result in a minimum of patient discomfort as well as instant relief from the symptoms of LER.
