[Simple endoscopic positioning of a double-barrelled afterloading applicator based on the Seldinger principle]. / Einfache endoskopische Positionierung eines doppelläufigen Afterloading-Applikators nach dem Seldinger-Prinzip.

The endoluminal positioning of afterloading applicators without exact guidance may be time wasting and difficult in cases of unsteady or higher degree gastroenterological tumor stenosis. The open catheters, which were developed especially for this, will be pushed over a guidewire and have an obligatory contamination of catheter and radiation source with body secretions. For this case we have developed a double channeled afterloading applicator, which will give the advantages of the Seldinger technique with the safety of a closed system, combined with endoscopic guiding of the wire. With this technique we simplified the endoluminal radiation. Our method is safe, time saving and less stressful for the patients.
