Analysis of Polyp Treatment Using Argon Gas Knife under the Microscope

Gastrointestinal polyp carcinogenesis is a common type of digestive disease, and with the promotion of fiberoptic endoscopy, the detection rate of this disease has significantly increased. Clinical diagnosis of polyp cancer is often confirmed through endoscopic resection surgery, but there is no unified conclusion on whether surgical treatment is necessary. Argon knife resection does not cause pain and can alleviate the discomfort of gastroscopy intubation, resulting in higher treatment comfort.

Endoscopic electrocoagulation or microwave therapy are routine treatments for gastrointestinal polyps, but may cause abnormal reactions such as nausea and vomiting. Moreover, endoscopic examination can promote rapid peristalsis of the gastrointestinal tract, interfere with the clarity of the examination field, make it difficult to accurately locate the position of polyps, and easily lead to misdiagnosis or damage to the surrounding tissues of the gastrointestinal tract, ultimately inducing perforation or bleeding symptoms. The argon knife does not come into contact with gastrointestinal tissue during operation. It completes one electrocautery within 1-2 seconds through electrocoagulation technology, which can transfer the argon ion beam to the surface of gastrointestinal tissue. After the coagulation effect is produced, the effect is uniform and can dehydrate polyps. Electroargon ion beam can avoid high resistance tissues and flow towards low resistance tissues, so the solidification depth is limited and will not cause perforation. It does not adhere to tissues, has better control over bleeding area, and does not damage solid tissues. Continuous coagulation therapy can be performed with minimal damage, and argon gas is an inert gas that does not harm the human body. The incision will not undergo carbonization reaction, and the healing speed is fast. During operation, there will be no vaporization phenomenon, the field of view is clearer, and the operator is not affected by odors. More importantly, the surgical cost of argon gas knife resection is generally low, and it does not cause lesion metastasis or recurrence. The success rate is relatively high, which can improve the long-term efficacy of patients.

The polypectomy effect of painless endoscopic argon knife lesion resection is equivalent to traditional gastrectomy, but it has fewer complications and shorter surgical time. The reason is that painless endoscopy does not cause stress reactions in patients, can maintain stable vital signs, and avoid complications caused by surgical operations. Moreover, the precision of argon knife operation is high, and the use of electrocautery to remove polyps is less likely to cause bleeding or perforation, resulting in better safety.
