Laparoscopic Heller Myotomy with Partial (Dor) Fundoplication

Achalasia is a primary esophageal motility disorder characterized by lack of esophageal peristalsis and partial or absent relaxation of the lower esophageal sphincter in response to swallowing. Patients’ symptoms include dysphagia, regurgitation, aspiration, heartburn, and chest pain. This chronic disease has no cure, and the different treatment modalities aim to improve esophageal emptying and provide symptomatic relief. The laparoscopic Heller myotomy includes an esophageal myotomy, which is extended proximally for about 6 cm above the esophagogastric junction, and distally for about 2.5 cm onto the gastric wall. A partial fundoplication is added in order to prevent postoperative gastroesophageal reflux. A properly executed technique is critical for the success of the operation.
