Electroresection with a new endotracheally applicable resectoscope

Besides dilatation, cryotherapy, laser and surgical resection, the technique of endoscopic, endotracheal electroresection provides an alternative in the treatment of endotracheal stenoses. The instrument is similar to the resectoscope used in urology, but additionally equipped with a longer action range and respiration facility. It is insulated at the tip of the shaft. The electroresectoscope was employed on 64 occasions at our institution in three indications: endotracheal diseases, granulomas following tracheostomy; and short subglottic membrane stenoses, partly secondary to long-term intubation. Indications, advantages and drawbacks of the method are discussed.
