Gastrointestinal polyps (gastricpolyp) are benign elevated lesions that are confined to the mucosa of the digestive tract. The disease is asymptomatic in its early stages or in the absence of complications. When symptoms appear, they are often characterized by discomfort such as vague pain in the upper abdomen, bloating, diarrhea, and in some cases, nausea and vomiting. Gastrointestinal polyps are bulging lesions that originate from the epithelial cells of the GI mucosa projecting into the GI tract. Barium x-ray and gastrointestinal endoscopy are the main methods to diagnose GI polyps. Gastrointestinal polyps themselves can be divided into proliferative and adenomatous pathology, with the latter having a higher cancer rate (30%-58.3%), so biopsy is used to identify and determine the clinical treatment plan. Endoscopic treatment: Endoscopic resection is the preferred method for the treatment of gastrointestinal polyps, mainly high-frequency electrocoagulation resection, laser and microwave cautery, nylon wire ligation and argon ion coagulation. Endoscopic treatment of polyps is simple, less damaging and less expensive, and most of them are one-time treatment, while a few need to be removed in stages. Regular follow-up by endoscopy can also detect the recurrence of polyps and provide timely treatment to prevent cancer.
