Gastric Outlet Obstruction
About this trial
This is an interventional treatment trial for Gastric Outlet Obstruction
Eligibility Criteria
Inclusion Criteria:
GOO defined by symptoms resulting in decreased oral intake (nausea, vomiting and inability to eat),the obstruction was caused by primary distal stomach cancer and the site of stenosis was between the gastric body and duodenum bulb
Exclusion Criteria:
the presence of only mild symptoms in patients who could tolerate a liquid diet, clinical evidence of perforation or peritonitis, evidence of multiple small-bowel obstructions because of peritoneal seeding as well as diabetes or other diseases that affect gastric motility and use of promotility agents.

Tailored stents MTN-WE-20/100-A
Standard stents MTN-CG-s-20/100
The distal portion of the GOO tailored stents was semi-spherical, with a length of 20 mm, and a diameter of 28 mm. The middle segment had a diameter of 20 mm. The overall length of the stents was 100 mm. Both the middle part and the bottom of the proximal cup segment, and a part of the proximal funnel segment, were covered by a polyethylene membrane.
Standard uncovered stents were used in the control group. The ends of the stents were semi-spherical with diameters of 28 mm and length of 20 mm. The length of the stents was 100 mm
