Argon Plasma Coagulation (APC)

Argon Plazma Koagülasyon

Argon Plasma Coagulation (APC) is a medical endoscopic procedure used to control bleeding from certain lesions in the gastrointestinal tract and to shrink tumors where surgery is not recommended. APC involves the use of a jet of ionized argon gas (plasma) directed through a probe passed through an endoscope.

Argon plasma coagulation is a coagulation method used in gastrointestinal endoscopic procedures. It is used to achieve hemostasis (stop bleeding) and treat lesions.

APC is based on the principle of delivering electrical energy to the target tissue using argon gas. This causes vaporization of water in the tissue and subsequent coagulation, thus stopping bleeding or treating lesions.

Why is Argon Plasma Coagulation Performed?

The procedure is used to treat various conditions in the gastrointestinal tract:

  1. Bleeding Control: APC can rapidly stop gastrointestinal bleeding. It is especially effective for bleeding from vascular lesions such as ulcers and angiomas.
  2. Treatment of Lesions: APC is used for ablation of some lesions such as polyp residues, barret esophagus.
  3. Treatment of Residual Tissue: It is an effective method in the treatment of residual tissue after endoscopic resection.
  4. Prophylaxis: APC can also be used in the prophylactic treatment of lesions at risk of bleeding. This is especially true for small vascular lesions in high-risk areas.

Uses of Argon Plasma Coagulation Process

  1. Treatment of active gastrointestinal bleeding
  2. Coagulation of vascular lesions
  3. Treatment of residual adenoma tissue
  4. Ablation treatment of Barret’s esophagus

Advantages of the Procedure

  • It does not penetrate deep tissues, so the risk of complications is lower.
  • It is fast and effective for hemostasis.
  • It offers a more controlled treatment than other coagulation methods.

Side Effects and Complications

As with any medical procedure, APC has potential side effects. These include perforation, bleeding, infection and burns. However, with the right technique and in experienced hands, these risks are minimal.

Argon Plasma Coagulation is an effective method for the treatment of bleeding and some lesions in gastroenterology. However, it is essential that the procedure is performed under the supervision of an experienced endoscopist for its successful and safe implementation.

How is Argon Plasma Coagulation Performed?

Argon Plasma Coagulation (APC) is performed using a special device and an endoscope. The basic steps of the procedure are as follows:

  1. Preparation: Depending on the patient’s condition, local anesthesia or sedation may be administered. This ensures that the patient remains comfortable and immobilized.
  2. Advancing the Endoscope: The endoscope is advanced to the desired area with the help of a probe connected to the APC device.
  3. Application of Argon Gas: The APC device releases a thin stream of argon gas through the tip of the endoscope. This gas fills the space between the electrode and the tissue, creating an electrical conductivity.
  4. Coagulation: When an electric current is applied, argon gas turns into a plasma. This plasma transmits energy to the tissue, which causes coagulation (cooking) of the tissue. Coagulation occurs only on the surface, minimizing deep tissue damage.
  5. Termination of the Process: When the necessary coagulation is complete, the device is turned off and the endoscope is carefully removed.
