Anoscopic-assisted insertion of end-to-end anastomosing staplers

Widespread popularity of the double-stapler technique has created the potential for anal sphincter and anal canal injury during transanal insertion of the end-to-end anastomosing stapler. The Faensler operating anoscope helps eliminate that potential by symmetrically dilating the anal canal, thereby permitting atraumatic insertion of the end-to-end anastomosing stapler.
