We use the latest and advanced technology to provide individualized care for each patient with an accurate diagnosis and the right treatment.

To avoid any risk and complications, our pulmonologists collaborate with the experts from other medical specialties to ensure an integrative and multidisciplinary approach for our patient’s treatment and recovery.

What is Bronchoscopic Argon Plasma Coagulation (APC)?

Bronchoscopic Argon plasma coagulation (APC) is an electrosurgical procedure similar to laser or electrocautery. Bronchoscopic APC is utilized during bronchoscopic procedures to terminate malignant airway tumors, remove granulation tissue, control hemoptysis from stents or anastomoses, and treat a variety of benign disorders.

What to Expect During the Procedure?

Step 1: During the procedure, anaesthesia is given to the patient. On the patient’s back or thigh, a grounding pad is placed. The argon flow rate is determined at less than 1 L/min with 30 Watts power. A bronchoscope is inserted through a small incision, and the probe tip is positioned several centimeters beyond the bronchoscope’s tip to prevent its burning. From the target lesion, the probe tip is placed away at 1 cm. Surgeons ensure that the catheter does not come into direct contact with the target tissue.

Step2: The argon gas is expelled at a high-voltage electric current. The current passes along the probe, which put it in contact with the gas, ionizing it and conducting a monopolar current to the target lesion. When the current is applied to the surface, the tissue bursts within seconds.

APC is applied to the underlying fresh tissue, and the process is repeated continuously until the tumor is removed. When the tumor is ablated, then APC may be applied to the tumor base to mitigate the risk of post-procedure bleeding from the area.

What are the Benefits of Using APC?

The following are the advantages of using Bronchoscopic Argon Plasma Coagulation:

  • Ease of application
  • Speedy treatment of multiple lesions in the case of angiodysplasias or wide areas
  • Safety because of reduced depth of penetration
  • Lower cost compared to laser.
