[Usefulness of the stent through percutaneous endoscopic gastrostomy for pyloric stenosis].

The stent treatment using a self expandable metallic stent (EMS) can improve the pyloric stenosis with inoperable advanced cancer. This stent treatment is minimally invasive, and the patients can take a meal immediately after the treatment. However, a placement of a stent using an endoscope is difficult because straightening up the endoscope in the stomach is an impossible task in the case of using an oral endoscope. Therefore, we used PEG and we could easily place the EMS through PEG for pyloric stenosis. We report the three cases of pyloric stenosis with an inoperable advanced gastric and pancreas cancers using this technique. In all cases, pyloric stenosis were improved, and they could take it from a mouth and could receive home care for a while. We think this technique is feasible and beneficial.
