The largest study of endoscopic mucosal resection by the Australian Consortium included 1000 cases and long term surveillance. [2] After exclusion of 79 unresectable lesions, the remainder were treated by endoscopic mucosal resection. Overall 98.1% were disease free at the end of two rounds (typically at 6 and 18 months) of follow up.
The non-lifting sign was first described in 1994 by Yoshiharu Uno and Akihiro Munakata of the Hirosaki University School of Medicine, Japan. [2]In 1999 the same team showed that the presence of a non-lifting sign correlated with the depth of invasion of the submucosa by early colorectal cancers that were being considered for endoscopic resection.

Endoscopic submucosal dissection (ESD) is an advanced surgical procedure using endoscopy to remove gastrointestinal tumors that have not entered the muscle layer. ESD may be done in the esophagus, stomach or colon. Application of endoscopic resection (ER) to gastrointestinal (GI) neoplasms is limited to lesions with no risk of nodal metastasis.
Polyps may be removed using cold biopsy forceps, cold snare polypectomy, hot biopsy forceps, hot snare polypectomy, endoscopic mucosal resection, or endoscopic submucosal dissection. Cold biopsy forceps may be used for small (diminutive) polyps 1-3 mm in size. [3]
Haruhiro Inoue is a Japanese thoracic surgeon and endoscopist best known for the development of the cap endoscopic mucosal resection technique, and the first per-oral endoscopic myotomy performed in humans. [1] He is a professor at Showa University and Director of the Digestive Disease Centre at Showa University Koto-Toyosu Hospital in Tokyo ...
Treatments for early-stage colon or colorectal cancer can include a polypectomy, or the removal of polyps during a colonoscopy, or endoscopic mucosal resection, which is the removal of larger ...
Endoscopic surveillance of people with Barrett's esophagus is often recommended, although little direct evidence supports this practice. [1] Treatment options for high-grade dysplasia include surgical removal of the esophagus (esophagectomy) or endoscopic treatments such as endoscopic mucosal resection or ablation (destruction). [1]
Endoscopic mucosal resection involves removal of the mucosal layer, and in order to be done safely, a submucosal injection of dye is performed to ensure integrity at the beginning of the procedure. Female uterine submucosal layers are liable to develop fibroids during pregnancy and are often excised upon discovery. [1]
