Argon plasma coagulation

چکیده
Argon Plasma Coagulation (APC) is an application of gas discharges in argon in electrosurgery, which is increasingly used especially in endoscopy. The major application fields are haemostasis, tissue devitalization and tissue reduction.This review describes the physics and technology of electrosurgery and APC. Some characteristics of the argon discharge are shown and discussed, and thermal effects in biological tissue are described. Subsequently, examples of medical applications are given.

In Vitro and in Vivo studies of the Effects of Cold Argon Plasma on Decreasing the Coagulation Time
Introduction Cold plasma is a self-sterilized, painless, and non-contact method in surgeries. These properties allow it to be applied to the living tissues and heat-sensitive parts. The aim of this study was to design a new cold plasma producer device and evaluate the effects of cold argon plasma on decreasing the coagulation time of blood drop in vitro and that of the injured liver blood in vi...
متن کاملSymptomatic gastric inlet patches in children treated with argon plasma coagulation: a case series.
The pathologic potential of gastric inlet patches is now being recognized. A recent adult study has shown the effectiveness of argon plasma coagulation in ablating the patch and the associated symptoms. There are no reports of ablation in children. We report a case series of successful argon plasma coagulation of gastric inlet patches and their symptoms in 5 children.
متن کاملArgon Plasma Coagulation in Barrett’s Esophagus: The Most Widely Available Technique
Argon plasma coagulation (APC) is the most widely available technique for ablation of Barrett’s esophagus. When the argon plasma is applied, thermal injury to the epithelium results. The depth of injury is the function of the voltage, the gas flow, and the pressure applied to the probe. A series of 32 patients with high-grade dysplasia were treated with APC with 34 months of follow-up. Dysplasia
متن کاملColonic injury from electric arcing: a significant complication of argon plasma coagulation.
Argon plasma coagulation is increasingly used in endoscopic haemostasis. This case report illustrates the potential for thermal injury at a staple line remote from the area of argon plasma coagulation treatment as a result of electrical arcing. Increasing numbers of colorectal anastomosis and reconstruction procedures are now being performed using stapling techniques and the use of argon plasma...
متن کامل[Argon-plasma coagulation as a primary therapeutic method for the treatment of flat duodenal adenomas].
BACKGROUND Argon-plasma coagulation is a method for tissue coagulation that uses high-frequency electric energy and ionized argon gas. It is used in endoscopic haemostasis and in coagulation of smaller, superficial lesion on gastrointestinal mucosa such as flat adenomas, but also in reduction of tumor tissue. CASE REPORT We presented a patient with flat adenoma duodeni. Adenoma had been treat...
