[Wallflex duodenal stenting for gastric outlet obstruction caused by inoperable advanced gastric cancer].
BACKGROUND
Wallflex duodenal stent (WDS) placement for gastric outlet obstruction caused by malignant disease has been covered by health insurance in Japan since April 2010. We have placed five-WDS for three gastric outlet obstructions caused by inoperable advanced gastric cancer. CASE 1: A 67-year-old male diagnosed as having Stage IV gastric cancer with liver, lung, and lymph node metastases underwent a WDS placement during first-line chemotherapy. He was able to consume a soft diet orally for about five months thereafter. He underwent a WDS replacement for stent obstruction by tumor ingrowth and finally died due to the primary tumor 11 months after the first visit. CASE 2: A 63-year-old male diagnosed as having Stage IV gastric cancer with liver and lymph node metastases underwent a WDS placement during the first-line chemotherapy. He was able to consume a soft diet orally for about three months thereafter. He died due to the primary tumor six months after the first visit. CASE 3: A 72-year-old male diagnosed as having Stage IV gastric cancer with liver and lymph node metastases underwent a WDS placement during the first-line chemotherapy. He was able to consume a soft diet orally for about four months and subsequently received the fourth-line chemotherapy. He underwent a WDS replacement for stent obstruction by tumor ingrowth and finally died due to the primary tumor nine months after the first visit.


CONCLUSIONS
WDS stent placements for gastric outlet obstruction caused by inoperable advanced gastric cancer were performed safely and enabled the consumption of a soft diet orally for at least three months. This approach is expected to be a safe and effective treatment option.
