    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 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 need for imaging assessment of small bowel diseases comes from the limits of traditional endoscopy in evaluating ileum loops, as other modern techniques such as capsule endoscopy are not routinely performed as it is seldom available in most centers. Over the past several years assessment of small bowel diseases was performed by Barium ...

    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 ...

    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. [3]

    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 ...
