Name of the Procedure:

Thymectomy, Partial or Total; Sternal Split or Transthoracic Approach, Without Radical Mediastinal Dissection (Separate Procedure)

Summary

A thymectomy is a surgical procedure to remove the thymus gland, either partially or entirely. This version of the procedure involves accessing the thymus through a sternal split or transthoracic approach without performing a radical mediastinal dissection.

Purpose

This procedure is typically performed to treat conditions such as myasthenia gravis, thymomas, or other mediastinal tumors. The goal is to alleviate symptoms related to these conditions by removing the thymus gland, which can sometimes help in reducing the severity of autoimmune responses or removing cancerous tissues.

Indications

• Persistent and severe myasthenia gravis not responding to medication
• Thymic tumors or cysts
• Other mediastinal masses
• Conditions causing an enlarged thymus

Preparation

• Patients may be instructed to fast for 8-12 hours before the procedure.
• Medications may need to be adjusted; blood thinners and certain immune-modulating drugs might need to be stopped ahead of time.
• Preoperative assessments include imaging studies like CT or MRI scans and blood tests.

Procedure Description

1. The patient is placed under general anesthesia.
2. A sternal split (median sternotomy) or a transthoracic approach is used to access the thymus gland.
3. The surgeon carefully removes either part or all of the thymus gland.
4. Hemostasis is ensured, and the surgical site is closed with sutures or staples.

Duration

The procedure typically takes between 1.5 to 3 hours, depending on the complexity and extent of the thymus removal.

Setting

This procedure is performed in a hospital setting, specifically in an operating room equipped for thoracic surgery.

Personnel

• Thoracic Surgeon
• Anesthesiologist
• Surgical Nurses
• Physician Assistants or Surgical Technicians

Risks and Complications

• Common risks: Infection, bleeding, and pain at the incision site
• Rare risks: Damage to surrounding structures (e.g., heart, lungs), pneumonia, respiratory complications, nerve damage
• Possible complications include prolonged drainage, scarring, and a need for additional surgery if complete removal wasn’t achieved.

Benefits

• Improvement in symptoms related to myasthenia gravis.
• Removal of potentially cancerous thymic tumors.
• Enhanced quality of life and potential reduction in medication dependence for autoimmune conditions.

Recovery

• Post-operative care involves monitoring vital signs and pain management.
• Patients usually stay in the hospital for 3-5 days.
• Recovery time typically spans 4-6 weeks.
• Restrictions on heavy lifting and strenuous activity during the recovery period.
• Follow-up appointments for wound check and monitoring progress.

Alternatives

• Medical management with medications alone for myasthenia gravis.
• Radiation therapy or chemotherapy for thymic tumors.
• Less invasive surgical techniques, which may involve video-assisted thoracoscopic surgery (VATS).

Patient Experience

• The patient will be under general anesthesia during the procedure, so they will not feel anything.
• Post-operative pain can be managed with medications.
• Some discomfort and restrictions in movement are expected during the initial recovery period.
• Gradual improvement in symptoms should be noticed after recovery from the surgery.
