Endoscopic minimally invasive treatment--from inside the lumen to outside the lumen, from the superficial layer to the deep layer / 中华胃肠外科杂志

ABSTRACT

Since the introduction of endoscopic submucosal dissection (ESD) in China in 2006, endoscopic minimally invasive treatment has experienced a booming development for more than 10 years, and its indications are gradually being expanded from inside the lumen to outside the lumen, from the superficial layer to the deep layer, from organic diseases to functional diseases. This article summaries the development of endoscopic minimally invasive resection in the past 10 years, from the perspective of mucosa, submucosa, muscularis, serosal and even extraluminal lesions, respectively, to introduce the role of endoscopic minimally invasive treatment. For mucosal lesions, ESD has become a first-line treatment for early gastric cancer; endoscopic treatment of colorectal lesions is still controversial in Europe and the United States, but is gradually being accepted. For submucosal tumors(SMT), the Expert Consensus for Endoscopic Diagnosis and Treatment of Submucosal Tumors in China (version 2018) was published in 2018, and the principles and related technical rules for gastrointestinal SMT have been highlighted. For serosal and even extraluminal lesions, natural orifice transluminal endoscopic surgery (NOTES) and tunnel endoscopic surgery, mainly including endoscopic myotomy (POEM) and endoscopic transmucosal tunneling tumor resection (STER), showed potential for development in preliminary studies, and showed good results in cholecystectomy, appendectomy, achalasia, gastroparesis and even extra-gastrointestinal tumor resection. This article describes the various endoscopic treatment techniques, and looks into their application prospects and future challenges.
