<unk>  is the medical term for an endoscopic procedure during which treatment is carried out via the endoscope. This contrasts with diagnostic endoscopy, where the aim of the procedure is purely to visualize a part of the gastrointestinal, respiratory or urinary tract in order to aid diagnosis. In practice, a procedure which starts as a diagnostic endoscopy may become a<unk>  depending on the findings, such as in cases of upper gastrointestinal bleeding, or the finding of polyps during colonoscopy. A number of different techniques have been developed to allow treatment to be carried out endoscopically, to treat disorders such as bleeding, strictures and polyps.
