TIPS AND TRICKS LIQUID NITROGEN CRYOTHERAPY-ASSISTED BALLOON DILATION FOR REFRACTORY STRICTURES

Video Transcription

Video Summary

Liquid nitrogen cryotherapy assisted balloon dilation is presented as an innovative treatment for refractory esophageal strictures, such as those resulting from caustic ingestion. This method involves a cryogen spray that freezes and thaws tissues, promoting healing without significant scarring. A case of a 28-year-old woman with a refractory stricture was discussed, showing successful outcomes with reduced dilations needed post-procedure. The technique uses a spray catheter within an endoscope and recommends a 360-degree freeze, followed by controlled balloon dilation. Though the optimal method is not yet standardized, initial results are promising for expanded applications.
