A special instrument for a safe and effective laparoscopic esophageal myotomy.

The authors describe the use of particular endoscopic scissors that allow a safe and easy laparoscopic performance of Heller myotomy. Although originally designed for another use, these scissors are extremely useful for esophageal myotomy, their most important feature being the smooth and insulated protection of the lower jaw. This feature keeps the mucosa constantly away from the myotomy and allows the safe use of electrocautery, resulting in a perfect hemostasis.
