磁锚定牵引消化道黏膜剥离术临床研究进展

Endoscopic submucosal dissection (ESD) is a mature method for treating early gastrointestinal tumors. Appropriate submucosal exposure is one of the important factors for the successful operation of effective and safe dissection. This article combines domestic and foreign literature to summarize the background, procedure, prognosis, characteristics and related clinical research of magnetic anchored-guided endoscopic submucosal dissection (MAG-ESD). Generally speaking, compared with traditional ESD, MAG-ESD can shorten the operation time, simplify operation steps, reduce the incidence of complications, and improve the learning curve. Compared with other traction technologies that assist ESD, magnetic anchor-assisted technology can be used in the whole digestive tract mucosal dissection to treat early-staged cancer. The operation has a better operation triangle, is less technically difficult, and is friendly to experienced endoscope operators. It is called the "second hand" of endoscope operators. It can greatly improve the clinical treatment efficiency and patient satisfaction of early gastrointestinal cancer.
