Official Description

Biliary duct stone extraction, percutaneous via T-tube tract, basket, or snare (eg, Burhenne technique)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 47630 involves the extraction of biliary duct stones through a percutaneous approach utilizing a T-tube tract. This technique is typically indicated for patients who have retained biliary stones following a prior surgical procedure where the common bile duct was explored, and a T-tube was placed to facilitate drainage. The extraction process employs a basket or snare device to capture and remove the stones effectively. The use of radiological guidance is essential in this procedure, as it allows for precise navigation to the site of the stones within the biliary duct. The basket extraction catheter is carefully maneuvered through the T-tube tract, ensuring that it reaches just proximal to the stone. Once in position, the basket is opened to ensnare the stone, and traction is applied to withdraw the basket along with the stone. Alternatively, a snare device may be utilized, following a similar technique for stone retrieval. This procedure is crucial for alleviating obstructions caused by biliary stones and restoring normal biliary function.

1. Indications

The procedure is indicated for the following conditions:

  • Retained Biliary Stones This procedure is performed for patients who have retained stones in the biliary duct following a previous surgical intervention.
  • Obstruction of the Biliary Duct The extraction is necessary to relieve obstruction caused by the presence of stones in the biliary system.
  • Post-Surgical Complications It is indicated in cases where complications arise after the exploration of the common bile duct and placement of a T-tube.

2. Procedure

The procedure consists of several key steps that ensure the effective extraction of biliary stones:

  • Step 1: Preparation and Imaging Prior to the extraction, the patient is positioned appropriately, and imaging studies are performed using radiological guidance to identify the location of the retained biliary stones. This imaging is crucial for planning the approach and ensuring accurate navigation during the procedure.
  • Step 2: Insertion of the Basket Extraction Catheter A basket extraction catheter is then inserted into the T-tube tract. The basket is initially closed to facilitate its advancement through the tract. The catheter is carefully maneuvered to reach the area just proximal to the biliary stone, ensuring that it is positioned correctly for effective extraction.
  • Step 3: Capturing the Stone Once the basket extraction catheter is in place, the basket is opened to capture the biliary stone. This step requires precision to ensure that the stone is securely held within the basket before any traction is applied.
  • Step 4: Extraction of the Stone After the stone is captured, traction is applied to the basket extraction catheter. The catheter, along with the stone, is then carefully withdrawn from the biliary duct through the T-tube tract. This step is critical to ensure that the stone is removed without causing damage to the surrounding biliary structures.
  • Step 5: Alternative Snare Extraction If necessary, a snare type device may be employed as an alternative to the basket. The snare extraction is performed in a similar manner, where the snare is positioned around the stone, tightened, and then withdrawn to remove the stone from the biliary duct.

3. Post-Procedure

Post-procedure care involves monitoring the patient for any complications that may arise following the extraction. Patients may require follow-up imaging to ensure that all stones have been successfully removed and to assess the patency of the biliary duct. Additionally, healthcare providers should observe for signs of infection or other adverse reactions. The recovery process may vary depending on the individual patient's condition and the complexity of the procedure performed.
