Laparoscopic esophagomyotomy for achalasia in children: A review

Figure 6 Myotomy with hook cautery. Electrocautery is used to begin the myotomy. It is performed at the 11 o’clock position on the anterior surface of the esophagus, taking care to avoid injury to the overlying vagus nerve. Once the submucosa is visible, blunt dissection is then typically employed to fully expose the mucosa.
