Discovery of early gastric cancer, can avoid the knife – health Sohu-freyja

Discovery of early gastric cancer, can avoid the knife – Sohu with the development of health health screening methods, and the number of tumor early detection, early detection of malignant tumor is extremely unfortunate – have the opportunity to achieve radical resection. Stomach cancer, if found early, or even avoid a knife. Early surgery can avoid why gastric cancer found it, because of early gastric cancer confined to the gastric mucosa and submucosa, with resection in endoscopic technology mature early cancer, similar to the process of gastroscopy, not from the belly operation from the gastric resection, direct removal of diseased tissue from the stomach cavity. As shown below, gastric cancer is developed from the gastric mucosa, with the growth of the tumor, the infiltration of the submucosa, muscularis, breakthrough serosa and lymph node metastasis and distant metastasis. Early gastric cancer refers to limited to the submucosal carcinoma, endoscopic techniques can now dig up the roots, complete resection of the tumor, but it is the premise of early discovery. If the tumor through the submucosa is prone to lymph node metastasis, endoscopic complete resection cannot now need surgery or chemotherapy. Endoscopic submucosal dissection (ESD) is a new technique developed on the basis of endoscopic mucosal resection (EMR). ESD can completely remove the lesion, to achieve the effect of digestive tract tumors. What are the advantages of endoscopic submucosal dissection? In the early stage of digestive tract cancer, surgical treatment is the main treatment, but the trauma is large. As long as the operation clearance, the case for ESD and traditional radical surgery effect is equivalent, this time ESD has the advantage to show up: the damage is small, low cost, postoperative recovery fast.

What is the safety of endoscopic submucosal dissection? Like other endoscopic treatments, ESD has a certain degree of risk. The main complications were hemorrhage, perforation, the incidence rate is about 5% – 8%. For bleeding in electrocoagulation or using titanium clips and other methods to control bleeding under endoscope, can effectively prevent intraoperative and postoperative application of hemostatic drugs before and after surgery; perforation complicated with ESD is usually very small, generally can be found in the operation, to titanium clip suture, gastrointestinal decompression, fast cure prevention and treatment of infection after operation method, a few patients need surgical treatment. To adapt to the scope of strict, limited to early gastric cancer ESD adaptation range is limited to the mucosa and submucosa of the early cancer, precancerous lesions, benign polyps and other indications of ESD. Early gastric cancer, esophageal cancer is usually found in gastroscope, preoperative endoscopic ultrasonography to determine the depth of invasion, to understand whether there is regional lymph node metastasis, to ensure the integrity of the lesion. After CT and other clinical imaging evaluation, to confirm the tumor in the early stage of the tumor is small, there is no evidence of lymph node metastasis, you can choose to remove the tumor under endoscopy. If the tumor breaks through the submucosa, it is impossible to ensure the complete resection of the tumor by endoscopic resection. If there is no guarantee of radical treatment, it will lose the significance of endoscopic resection.相关的主题文章:
