What is the main goal when injecting Botox into the lower esophageal sphincter for achalasia?

The main goal of injecting Botox into the lower esophageal sphincter for achalasia is to reduce lower esophageal sphincter pressure. Achalasia is characterized by the failure of the lower esophageal sphincter to relax during swallowing, leading to increased pressure and difficulty in swallowing. By injecting Botox, which is a neurotoxin that temporarily paralyzes the muscles, the pressure in the lower esophageal sphincter can be alleviated. This reduces the resistance during swallowing, allowing food to pass more easily into the stomach.

While other choices address important aspects of achalasia treatment, the primary aim of Botox injection specifically targets the reduction of the sphincter’s pressure, which is vital for symptom relief. For surgical interventions like myotomy, understanding the pressure dynamics is essential, but the direct action of Botox is focused on providing immediate relief from the high resting tone of the sphincter, thereby facilitating better passage of food and beverages without further complicating surgical outcomes.
