Name of the Procedure:

Mediastinoscopy; includes biopsy(ies) of mediastinal mass (e.g., lymphoma)

Summary

A mediastinoscopy is a surgical procedure used to examine the mediastinum, the area in the central part of the chest between the lungs. This procedure often involves taking a biopsy of tissue from mediastinal masses to diagnose conditions such as lymphomas.

Purpose

Mediastinoscopy is primarily performed to diagnose cancerous and non-cancerous conditions affecting the mediastinum, such as lymphomas, infections, or other masses. The goal is to obtain tissue samples for histological examination to aid in accurate diagnosis and inform appropriate treatment plans.

Indications

• Enlarged lymph nodes or masses detected on imaging studies like X-rays or CT scans.
• Suspected lymphoma or other types of cancer in the mediastinum.
• Unexplained symptoms such as persistent cough, chest pain, or weight loss.
• Patient not responding to standard treatments for suspected conditions.

Preparation

• Patients are generally required to fast for 8-12 hours before the procedure.
• Certain medications may need to be paused or adjusted as per the doctor's instructions.
• Pre-procedural diagnostic tests may include blood tests, chest X-rays, or CT scans.
• Patients should inform their doctor about any allergies, existing medical conditions, and medications.

Procedure Description

1. The procedure is performed under general anesthesia.
2. A small incision is made at the base of the neck.
3. A mediastinoscope (a thin, flexible tube with a camera and light) is inserted through the incision.
4. The doctor views the mediastinum and uses specialized instruments to take tissue samples from any abnormal areas.
5. The samples are sent to a lab for analysis.
6. The mediastinoscope is then removed, and the incision is closed with sutures.

Duration

The procedure typically takes about 1 to 2 hours.

Setting

Mediastinoscopy is usually performed in a hospital's operating room or a specialized surgical center.

Personnel

• Thoracic Surgeon
• Anesthesiologist
• Surgical Nurse
• Pathologist (for biopsy analysis)

Risks and Complications

• Common risks: soreness at the incision site, minor bleeding, infection.
• Rare but serious risks: injury to surrounding structures (like blood vessels, trachea), excessive bleeding, complications from anesthesia.

Benefits

• Accurate diagnosis of mediastinal masses.
• Helps determine the best course of treatment.
• Minimally invasive with generally quick recovery time compared to more extensive surgeries.

Recovery

• Post-procedure monitoring in a recovery room for several hours.
• Instructions for at-home care include keeping the incision site clean and dry.
• Mild pain and discomfort are typically managed with prescribed pain medications.
• Most patients can resume normal activities within a week.
• Follow-up appointments are required to discuss biopsy results and further treatment.

Alternatives

• Needle biopsy: Less invasive but may not provide as comprehensive a sample.
• PET/CT scans: Non-invasive; useful for detecting abnormal masses but not for obtaining tissue samples.
• Watchful waiting: Monitoring condition with regular follow-ups, applicable in less severe cases.

Patient Experience

• During the procedure: Patients are under general anesthesia and will not feel pain or be aware of the procedure.
• After the procedure: May experience mild sore throat or neck pain, managed with pain relief medications.
• Recovery involves mild discomfort, and patients are generally able to return to normal activities within a few days.
