[Management of complications in endoscopic interventions of the upper gastrointestinal tract]

Endoscopic procedures are frequently performed interventions in the clinical routine. Whereas endoscopy was initially regarded as being a secondary diagnostic tool, over the last decades endoscopic procedures have now become an integral part of various treatment strategies. The appeal of these methods is without any doubt the minimally invasive approach in contrast to open surgery. Endoscopic interventions per se necessitate representative technical equipment and the various components are continually being refined. Considering the complexity of the method, profound skills in endoscopic diagnostic procedures and therapeutic interventions are essential prerequisites for adequate procedural quality and patient safety. Endoscopic examinations are in fact invasive interventions in the same way as surgical procedures and are associated with a certain risk of potential complications. The awareness about potential complications and their respective risk factors is of crucial importance for both the patient and the physician. Complications may harm patients and may lead to increased mortality rates; therefore, it is not only important to be aware of them but also to have an efficient management strategy in order to minimize the damage. Recognition and consistent actions are the basic pillars of correct complication management. These aspects are addressed in this article.
