Gastrointestinal discomfort to the hospital for gastroscopy, colonoscopy, the results found that the esophagus, stomach, duodenum or colon “tumor”, what to do? Let Dr. Jia Fang tell you: 1. First, consult with the gastroenterology endoscopist to find out whether the tumor is benign or malignant. If the tumor is diagnosed as “cancer” or “sarcoma”, it is a malignant tumor and needs surgery or chemotherapy or radiotherapy in medical oncology. 3. If the tumor is diagnosed as “polyp”, “mesenchymal tumor”, “smooth muscle tumor”, “ectopic pancreas”, “yellow tumor”, or “sarcoma”, then it is a malignant tumor. Yellow tumor”, “papilloma”, “adenoma”, “verrucous gastritis”, “squamous epithelioma”. “squamous epithelioma”, etc., that are benign tumors, and benign tumors of the digestive tract can generally be given endoscopically for removal today with highly developed endoscopic treatment techniques. Endoscopic resection of benign tumors of the digestive tract is less painful and less costly than surgical treatment! If the tumor cannot be removed endoscopically, surgical resection can be considered. 4.If the tumor is diagnosed as “atypical hyperplasia” or “endothelioma”, we should be alert to the fact that it is a precancerous lesion between benign and malignant and may develop into cancer, which needs to be treated seriously. It can be observed; or it can be considered to be removed. 5.There are different methods of endoscopic treatment for different benign tumors (electrodissection, electrocoagulation, laser coagulation, laser vaporization, argon knife coagulation, ligature, etc.); there are also different excisional treatment methods for the same tumor according to its morphology and size (electrodissection, electrocoagulation, argon knife coagulation, laser coagulation vaporization, ligature, etc.); each excisional treatment method has its own strengths and weaknesses.
