微波组织凝固技术对上消化道出血的止血是迄今为止的最新疗法之一。我们成功地应用内窥镜—微波技术对8条狗的实验性上消化道出血进行止血,对小动脉和小静脉出血均取得很好的止血效果。凝固止血的血管最大直径小动脉是2mm,小静脉是2～3mm。微波电缆凝固器的内针可被插入靶组织,因此能够准确地使后者凝固止血。MTC在胃壁上形成的凝固性坏死和热的创伤能的四周内愈合。无任何并发症。 Microwave coagulation technology for hemostasis of upper gastrointestinal bleeding is by far one of the latest therapies. We successfully applied endoscopy-microwave technology to eight dogs in experimental upper gastrointestinal bleeding to stop bleeding, both small arteries and small venous hemorrhage achieved good hemostatic effect. Coagulation to stop the blood vessels of the largest diameter of small arteries is 2mm, small veins is 2 ~ 3mm. The inner needles of a microwave cable coagulator can be inserted into the target tissue, thus allowing the latter to coagulate to stop bleeding exactly. MTC heals within 4 weeks of coagulation necrosis and thermal trauma formed on the stomach wall. No complications.
