What is argon beam diathermy?
Listen to pronunciation. (AR-gon beem coh-A-gyuh-LAY-ter a-BLAY-shun) A procedure that destroys tissue with an electrical current passed through a stream of argon gas to the tissue. It is used to treat endometriosis and other conditions, and to stop blood loss during surgery.
How is argon used in surgery?
Argon plasma coagulation (APC) is a medical endoscopic procedure used to control bleeding from certain lesions in the gastrointestinal tract. It is administered during esophagogastroduodenoscopy or colonoscopy….

What type of electrosurgical unit is argon?
Argon plasma coagulation (APC) is a monopolar electrosurgical technique which uses argon discharges at atmospheric pressure to coagulate tissue. Argon was chosen because it is biochemically inert, has a low breakdown voltage and is relatively inexpensive.
What is Argon Plasma Coagulation used for?
Argon plasma coagulation (APC), sometimes referred to as argon photocoagulation, is a medical procedure that uses argon gas during a colonoscopy or an upper endoscopy to control bleeding from certain lesions in the gastrointestinal tract.
Which is an advantage of using the argon beam coagulator?
The theoretical advantages of APC include its ease of application, speedy treatment of multiple lesions in the case of angiodysplasias or wide areas (the base of resected polyps or tumor bleeding), safety due to reduced depth of penetration, and lower cost compared with laser.
What is electrocautery machine?
During electrocautery, current does not enter the patient’s body. Instead, current flows through a heating element, which burns the tissue by direct transfer of heat. Electrocautery or, more precisely, thermocautery units (Figure 3) are usually portable battery powered devices that can be either disposable or reusable.
Is the argon beam coagulator a laser?
Contrary to a common misconception, argon plasma coagulation (APC) is not a laser. This technology uses argon gas to deliver plasma of evenly distributed thermal energy to a field of tissue adjacent to the probe.
How hot is argon plasma?
Argon ICP plasma discharge temperatures are typically ~5,500 to 6,500 K and are therefore comparable to that reached at the surface (photosphere) of the sun (~4,500 K to ~6,000 K).
What is an electrosurgical generator?
An electrosurgical unit (ESU) consists of a generator and a handpiece with one or more electrodes. The device is controlled using a switch on the handpiece or a foot switch. Electrosurgical generators can produce a variety of electrical waveforms. As these waveforms change, so do the corresponding tissue effects.
What color is argon plasma?
Color
| Gas | Color |
|---|---|
| Neon | Red-orange |
| Argon | Violet to pale lavender blue |
| Krypton | Gray off-white to green. At high peak currents, bright blue-white. |
| Xenon | Gray or blue-gray dim white. At high peak currents, very bright green-blue. |
When is electrocautery used?
Electrocauterization (or electrocautery) is often used in surgery to remove unwanted or harmful tissue. It can also be used to burn and seal blood vessels. This helps reduce or stop bleeding during surgery or after an injury.
How is argon beam coagulation used in electrosurgical?
Argon-enhanced coagulation, also known as argon beam coagulation, is radio-frequency coagulation from an electrosurgical generator that delivers monopolar current through a flow of ionized argon gas. The risks related to this modality are similar to those for monopolar electrosurgery with the addition of the risk for gas emboli. 4
What can argon beam therapy be used for?
Argon beam therapy is a modern, safe form of heat (cautery) treatment for some diseases of the bowel and stomach lining. It allows the doctor to produce controlled burning of the superficial tissue without producing deep damage. It is useful for treating bleeding areas, small cancers or polyps.
How is argon plasma coagulation used in gastroenterology?
Argon plasma electrocoagulation is an effective and relatively low-cost alternative to laser therapy in gastrointestinal endoscopy. Argon plasma coagulation (APC) in gastroenterology: experimental and clinical experiences
Which is better, argon plasma or laser therapy?
Argon plasma electrocoagulation is an effective and relatively low-cost alternative to laser therapy in gastrointestinal endoscopy. Argon plasma electrocoagulation is an effective and relatively low-cost alternative to laser therapy in gastrointestinal endoscopy.
