Biopsy of lacrimal sac
CPT4 code
Name of the Procedure:
Biopsy of Lacrimal Sac
- Common Name: Lacrimal Sac Biopsy
- Medical Term: Dacryocystobiopsy
Summary
A biopsy of the lacrimal sac involves removing a small tissue sample from the lacrimal sac, a duct that drains tears from the eye into the nose. This tissue sample is then examined under a microscope to diagnose or rule out certain medical conditions.
Purpose
This procedure is conducted to investigate and diagnose underlying conditions affecting the lacrimal sac, such as infections, chronic dacryocystitis (inflammation), tumors, or other abnormal growths. The goal is to identify the cause of symptoms and determine the best course of treatment.
Indications
- Chronic, recurrent infections of the lacrimal sac
- Persistent tearing (epiphora)
- Pain, redness, or swelling near the inner corner of the eye
- Suspicion of a tumor or abnormal growth in the lacrimal sac
- Investigation of unexplained symptoms affecting the lacrimal drainage system
Preparation
- Patients may be required to fast for a few hours before the procedure.
- Instructions on medication adjustments, particularly blood thinners, will be provided.
- Preoperative assessment may include imaging tests such as a CT scan or MRI of the area.
- An evaluation of the patient’s medical history and current health status.
Procedure Description
- The patient is positioned comfortably, usually lying down.
- Local anesthesia is administered to numb the area around the lacrimal sac.
- The surgeon makes a small incision near the lacrimal sac to expose the tissue.
- Using specialized instruments, a small tissue sample is carefully excised.
- The tissue sample is preserved and sent to a pathology lab for analysis.
- The incision is closed with sutures or adhesive strips, and a sterile bandage is applied.
Duration
The biopsy procedure typically takes about 30 to 60 minutes, although this may vary based on individual circumstances.
Setting
The procedure is usually performed in an outpatient surgical center or hospital.
Personnel
- Ophthalmologist or Oculoplastic Surgeon
- Surgical Nurses
- Anesthesiologist, if sedation is required
Risks and Complications
- Infection at the biopsy site
- Bleeding or hematoma formation
- Scarring or adverse cosmetic outcome
- Temporary discomfort or swelling
- Rarely, damage to surrounding structures such as the eye
Benefits
- Accurate diagnosis of underlying conditions affecting the lacrimal sac
- Information that helps guide effective treatment plans
- Relief of symptoms once appropriate treatment is implemented
- Peace of mind from knowing the exact nature of the issue
Recovery
- Patients may experience mild pain or discomfort, which can be managed with over-the-counter pain relievers.
- Keeping the area clean and dry as instructed by the healthcare provider.
- Avoiding strenuous activities and heavy lifting for a few days.
- Follow-up appointments to monitor healing and review pathology results.
- Full recovery is usually expected within 1 to 2 weeks.
Alternatives
- Imaging studies alone (e.g., CT or MRI) to non-invasively assess the lacrimal sac.
- Diagnostic tear duct irrigation to assess the drainage system.
Less invasive treatments for managing symptoms without a definitive diagnosis, such as antibiotics or anti-inflammatory medications.
Patient Experience
- During the procedure, patients should feel minimal pain due to local anesthesia.
- Post-procedure discomfort is typically mild and short-lived.
- Clear post-procedure instructions and pain management plans will be provided to ensure patient comfort and a smooth recovery.
