Stellenwert interventioneller endoskopischer Verfahren

Interventional endoscopy has seen significant progress during recent decades. Also in palliative medicine have these advances improved the endoscopic treatment modalities for tumor patients. This article aims to provide an overview of interventional endoscopic techniques but also highlight their limitations in gastrointestinal cancer. In most cases, stents are used to restore intestinal passage or biliary flow. Technical advances, particularly in endosonography, have enabled new access routes for biliary drainage and gastric outlet obstruction. Furthermore, ablative techniques such as radiofrequency ablation are routinely used in inoperable palliative patients with biliary stenosis. In order to enable clinical decision-making, the various methods are described in the context of their effectiveness, risks, and limitations.
