Cardiac spasm, also known as Achalasia, is a rare disease of the esophagus, ranked second after esophageal cancer. The overall frequency is 6 cases/100,000 population/year.

Esophageal cancer is the most common cancer today, with an increasing incidence of this disease. The treatment for patients with esophageal cancer is esophagectomy. If detected at an early stage, when cancer cells have not spread, partial or total esophagectomy can treat cancer.

Esophagectomy will remove an important part of the digestive system, so patients must follow a gastric tube and take other precautions to quickly recover their health.

Achalasia is a disease that seriously affects the patient's quality of life. To treat achalasia, patients can use medication, surgery or balloon dilation. Of these, balloon dilation is widely used today.

Esophageal cancer is the 8th most common cancer in the world and has the poorest prognosis because when clinically detected, the tumor is often at an advanced stage.

Esophageal reconstruction by colon without thoracotomy is a safe and effective method of treating esophageal cancer today. However, esophagectomy and endoscopic esophagectomy through the thoracoabdominal approach still have some complications during the procedure that patients need to be aware of.
