Disposable device and a minimally invasive technique for rubber band ligation of hemorrhoids

Abstract

A disposable syringe-like hemorrhoid ligator was invented to simplify the banding procedure for both patient and surgeon. This single-operator ligator, with its own suction mechanism and easy loading features, was designed for use without the need of an assistant or an anoscope. By pointing the ligator directly toward the appropriate site and by measuring the distance from the anal margin using reference markings on the ligator, the bands can be placed accurately in a blind manner inside the rectum for the treatment of symptomatic internal hemorrhoids. Before the band is discharged, rotating the ligator through 180 degrees while applying suction will cause pain and give warning if the application site is not appropriate. In 480 patients treated to date, this technique was found to be well accepted and accurate, and the final results seem to be comparable to other methods of banding.
