Imaging-Guided Wide Local Excision

Imaging-guided wide local excision is a surgical procedure used to remove a tumor or a suspicious lesion from the body, typically from the breast, skin, or other soft tissues. The procedure combines imaging technologies with surgical techniques to ensure accurate and complete removal of the affected tissue.

Indications

The procedure is usually indicated for:

• Diagnosed or suspected cancerous tumors that are localized and have not spread to other parts of the body
• Benign (non-cancerous) tumors or lesions that are causing symptoms or pose a risk of becoming malignant
• High-risk lesions that require further examination and possible removal

Imaging Guidance

The procedure utilizes imaging modalities such as:

• Mammography: for breast lesions, to guide the surgeon during the excision
• Ultrasound: to visualize the tumor or lesion in real-time, allowing for precise removal
• Magnetic Resonance Imaging (MRI): for complex cases or when other imaging modalities are inconclusive
• Computed Tomography (CT) scans: occasionally used, especially for lesions in deeper tissues or when MRI is not feasible

Surgical Technique

The procedure typically involves:

• A small incision made in the skin to access the tumor or lesion
• Dissection and removal of the affected tissue, using imaging guidance to ensure complete excision
• Possible use of a specimen radiograph to confirm that the entire lesion has been removed
• Closure of the incision site, often with sutures or staples

Benefits and Risks

The benefits of imaging-guided wide local excision include:

• High accuracy in removing the tumor or lesion
• Potential for less invasive surgery compared to traditional methods
• Faster recovery times, depending on the location and size of the excised tissue

Risks and potential complications may include:

• Bleeding or hematoma at the surgical site
• Infection, as with any surgical procedure
• Scarring or changes in skin sensation
• Possible need for additional surgery if the lesion is found to be malignant or if margins are not clear

Post-Procedure Care and Follow-Up

After the procedure, patients typically require:

• Wound care and monitoring for signs of infection
• Pain management, as needed
• Follow-up appointments with their healthcare provider to review pathology results and discuss further treatment options, if necessary

It is essential to note that the specifics of the procedure may vary depending on individual patient needs and the preferences of the treating physician.

Frequently Asked Questions (FAQs)

What is an Imaging-guided wide local excision?
A surgical procedure that uses imaging technology to guide removal of a tumor or lesion with a margin of healthy tissue.

What types of imaging are used to guide the procedure?
Typically ultrasound, mammography, MRI, or CT scans, depending on the location and type of tumor.

What is the goal of a wide local excision?
To remove the tumor or lesion completely with a margin of healthy tissue to prevent recurrence.

Is a wide local excision a diagnostic or therapeutic procedure?
Both, as it can provide a diagnosis through pathology examination and treat the condition by removing the tumor.

What are the benefits of using imaging guidance during the procedure?
Improved accuracy in locating the tumor, reduced risk of incomplete removal, and potentially less damage to surrounding tissue.

Are there any risks or complications associated with the procedure?
Possible risks include bleeding, infection, scarring, and damage to surrounding tissues or organs.

How long does the procedure typically take?
Varies depending on the location and size of the tumor, but usually ranges from 30 minutes to several hours.

Will I be awake or under anesthesia during the procedure?
Typically under local or general anesthesia, depending on the location and extent of the procedure.

What is the typical recovery time after a wide local excision?
Usually several days to weeks, depending on the extent of the surgery and individual healing.

Will I need follow-up care or additional treatments after the procedure?
Possibly, as follow-up appointments may be necessary to monitor healing and remove sutures, and additional treatments may be recommended based on pathology results.
