Advanced interventional endoscopy encompasses a broad range of procedures that allow solutions to problems in the gastrointestinal tract to be performed endscopically. For instance minimally invasive endoscopic surgery can be performed for early cancers of the GI tract. Per-oral endoscopic myotomy allows the treatment of achalsia without an external cut.
Allows inspection of the lining of the gastrointestinal tract utilizing an endoscope and allows the endoscopist to perform surgical-type procedures from the inside.
Diagnostic endoscopy allows inspection of the lining of the gastrointestinal tract utilizing an endoscope. An endoscope is a flexible tube, approximately as thick as a pencil, with a tiny light and camera at the tip. It is passed into the intestines, through either the esophagus or rectum, and produces an image of the intestinal tract on a color monitor.
Interventional endoscopy provides the same opportunity for gastrointestinal inspection; however, it also allows the endoscopist to perform surgical-type procedures from the inside.
A channel within the endoscope provides a conduit to introduce miniature instruments for the endoscopist's use during examination and procedures. Miniature endoscopes can be passed through the channel enabling endoscopic procedures in the bile and pancreatic ducts. Tiny ultrasound transducers are even used to examine tiny lesions within the gastrointestinal tract.
Endoscopic Mucosal Resection (EMR)
EMR is an endoscopic technique developed for removal of flat lesions confined to the superficial layers of the GI tract. EMR is typically used for removal of lesions smaller than 2cm or piecemeal removal of larger lesions.
Endoscopic Submucosal Dissection (ESD)
ESD is an advanced endoscopic procedure used to remove gastrointestinal tumors that have not entered the muscle layer. ESD may be done in the esophagus, stomach or colon.
