Endoscopic options in oncology

Endoscopic diagnostic and therapeutic options in gastrointestinal oncology are summarized in this article. Endoscopic ultrasound greatly adds to the possibilities of endoscopy by expanding the view beyond the surface of the mucosa into the adjacent organs and making targeted interventions possible. Many guidelines have recently incorporated this elegant method. Furthermore, endoscopic treatment options for early cancer of the esophagus, the stomach and the colorectum are depicted. Advances in gastrointestinal stent technology as well as the established percutaneous enteral tubes make it easier to provide a tailored therapy in many curative and palliative oncologic situations.
