Abstract
Malignant gastroduodenal obstructions are a serious symptom in patients with stomach, pancreatico-biliary and metastatic cancers. Gastroduodenal stenting is now widely used as an alternative to surgical gastrojejunostomy.
There are two placement techniques : the over-the-wire (OTW) and through-the scope (TTS) methods. In the latter method, the entire procedure can be performed under endoscopic control. Therefore, the TTS method stent placement is much easier to complete as compared with the OTW method. The TTS method with a dedicated enteral stent is obviously a desirable technique, reducing the procedure time and lightening the burden on patients. However, the key to the successful treatment is that we should recognize the stent characteristics and choose the method appropriate to the stent to be used.
