The major advantages of an overtube include prevention of esophageal mucosal injury and aspiration. In addition, if numerous objects need to be extracted, the overtube provides a conduit for repeated endoscope insertion and withdrawal.

Overtubes were frequently used to facilitate repeated intubation and withdrawal during esophageal variceal band ligation with individually loaded bands; however, this practice has largely been obviated by currently available multiband ligators.
