Myotomy
Myotomy
Myotomy (pronounced: my-OT-uh-me) is a surgical procedure that involves cutting a muscle. This procedure is often used to treat conditions that prevent normal muscle functioning, such as achalasia and hypertrophic cardiomyopathy.
Etymology
The term "myotomy" is derived from the Greek words "myo," meaning muscle, and "tomy," meaning cutting.
Procedure
During a myotomy, a surgeon makes an incision in the muscle to relieve tension or pressure. This can help improve muscle function and alleviate symptoms associated with certain medical conditions. For example, in the case of achalasia, a myotomy can help relax the lower esophageal sphincter to allow food and liquid to pass into the stomach more easily.
Types of Myotomy
There are several types of myotomy procedures, including:
- Heller myotomy: This procedure is used to treat achalasia by cutting the outer muscle layers of the lower esophagus.
- Septal myotomy: This procedure is used to treat hypertrophic cardiomyopathy by removing part of the thickened heart muscle that is blocking blood flow.
Risks and Complications
Like any surgical procedure, a myotomy carries certain risks and potential complications. These may include infection, bleeding, and damage to surrounding tissues. In some cases, a myotomy may not fully alleviate symptoms, and additional treatment may be necessary.
