ABSTRACT

Objective To probe into the application of argon laser photo-coagulation (APC) in interventional endoscopic treatment of digestive diseases. Method 62 patients suffering from digestive diseases were treated with interventional endoscopic treatment with the aid of APC, including 393 cases of gastrointestinal polyps, 122 cases of gastritis verrucosa, 5 cases of Barrett's esophageal ulcer and 42 cases of hemorrhage of digestive tract. The effectiveness of the treatment was observed. Result For 350 cases of gastrointestinal polyp, in which the diameter of the polyp was less than 5 mm, the lesions were eliminated when checked by endoscopy 3 months after APC treatment, the curative ratio was 100%. For 43 cases of gastrointestinal polyps, in which the diameter of the polyp was larger than 5 mm, no residual lesions were found in 38 cases, and remarkable improvement was found in another 5 cases of Peutz-Jeghers syndrome. For 122 case of gastritis verrucosa, 116 cases recovered thoroughly, the curative ratio reached 95.1%. In 42 cases of hemorrhage of digestive tract, no hemorrhage was found in 41 cases after APC treatment. In 5 cases of Barrett′s esophageal ulcer treated with APC accompanied by PPIs, squamous cell epithelium was found to have recovered as shown by endoscopy and biopsy 3 months after the treatment, and no recurrence 12 months later. Conclusion APC can be widely used in digestive diseases including gastrointestinal polyps, hemorrhage of digestive tract, Barrett's syndrome, gastritis verrucosa, etc. APC has a special value for the treatment of gastrointestinal polyp when the diameter of the polyp was less than 5 mm, and also gastritis verrucosa.
