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.
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.

When a treatable lesion is identified on endoscopy (such as a bleeding vessel), an endoclip can be inserted through the channel of the endoscope until the sheathed clip is visible on the endoscopic image, and the handle for deployment handed to the nurse assistant. The clip is unsheathed by retraction at the handle, positioned, and "fired" by ...
Endoscopic mucosal resection has been shown to be less expensive and safer compared to surgical resection of large, non-invasive polyps of the bowel. [3] Endoscopic mucosal resection requires training to achieve proficiency. The Mayo Clinic Florida group reported that at least 100 procedures are needed to achieve proficiency. [4]
Any additional procedures are performed at this stage. The air in the stomach is aspirated before removing the endoscope. Still photographs can be made during the procedure and later shown to the patient to help explain any findings. In its most basic use, the endoscope is used to inspect the internal anatomy of the digestive tract.
Forms of endoscopic therapy have been used for stage 0 and I disease: endoscopic mucosal resection (EMR) [70] and mucosal ablation using radiofrequency ablation, photodynamic therapy, Nd-YAG laser, or argon plasma coagulation. Laser therapy is the use of high-intensity light to destroy tumor cells while affecting only the treated area. This is ...
An endoscopy is a procedure used in medicine to look inside the body. [1] The endoscopy procedure uses an endoscope to examine the interior of a hollow organ or cavity of the body. Unlike many other medical imaging techniques, endoscopes are inserted directly into the organ.
