Introduction:

Excisional biopsy is a common procedure used in the field of medicine to obtain a tissue sample for diagnostic purposes. It involves the removal of a suspicious or abnormal tissue or lesion from the body for further examination under a microscope. This article provides a comprehensive overview of excisional biopsy, including its purpose, types, procedure, indications, complications, and post-biopsy care. It aims to familiarize healthcare professionals and patients with the essential aspects of excisional biopsy.

Purpose of Excisional Biopsy:

• Diagnosis: The primary purpose of excisional biopsy is to obtain a tissue sample for accurate diagnosis of a suspected disease or condition.
• Characterization: Excisional biopsy helps in determining the nature, extent, and characteristics of abnormal tissue, such as identifying whether it is benign or malignant.
• Treatment Planning: The obtained tissue sample can aid in determining the appropriate treatment plan based on the specific diagnosis.

Types of Excisional Biopsy:

• Incisional Biopsy: In this type of biopsy, only a portion of the suspicious tissue is removed for analysis.
• Excisional Biopsy: This involves the complete removal of the entire lesion or abnormal tissue, including a margin of healthy tissue.

Procedure:

• Patient Preparation: The patient is positioned comfortably, and the area to be biopsied is cleaned and sterilized.
• Anesthesia: Local or regional anesthesia is administered to numb the area around the biopsy site, ensuring a painless procedure.
• Incision and Removal: The surgeon makes an incision around the target tissue and carefully removes the entire lesion or abnormal tissue, including a margin of healthy tissue if indicated.
• Hemostasis: Any bleeding from the biopsy site is controlled using various techniques, such as suturing, cauterization, or the application of hemostatic agents.
• Closure: The incision is closed using sutures or surgical staples, depending on the size and location of the biopsy site.
• Dressing and Post-Biopsy Care: A sterile dressing is applied to the wound, and specific post-biopsy care instructions are provided to the patient.

Indications for Excisional Biopsy:

• Suspicion of Cancer: Excisional biopsy is commonly used to investigate suspected malignant tumors or lesions.
• Suspicion of Benign Conditions: It is also employed to diagnose and characterize various benign conditions, such as cysts or fibromas.
• Diagnostic Uncertainty: When other diagnostic tests are inconclusive or unable to provide a definitive diagnosis, excisional biopsy may be recommended.

Complications of Excisional Biopsy:

• Bleeding: Some bleeding at the biopsy site is expected but can usually be controlled during the procedure.
• Infection: Proper sterile technique minimizes the risk of infection, but it is still a potential complication.
• Scar Formation: Excisional biopsy leaves a scar at the site of tissue removal, which may vary in size and appearance.
• Nerve or Vascular Damage: Rarely, nearby nerves or blood vessels may be affected during the procedure, leading to sensory or vascular complications.

Post-Biopsy Care:

• Wound Care: The patient is advised to keep the biopsy site clean and dry and follow any specific wound care instructions provided by the healthcare provider.
• Pain Management: Over-the-counter pain medications or prescribed analgesics may be recommended to manage any post-biopsy discomfort.
• Monitoring and Follow-Up: Patients should be monitored for signs of infection or other complications and scheduled for appropriate follow-up visits to discuss biopsy results and further treatment options.

Conclusion:

Excisional biopsy is a valuable procedure for obtaining tissue samples for accurate diagnosis and treatment planning. It plays a crucial role in determining the nature of abnormal tissue and guiding subsequent management decisions. Healthcare professionals should be familiar with the indications, procedure, potential complications, and post-biopsy care to ensure the safe and effective use of excisional biopsy in clinical practice.
