Abstract:
Objective To evaluate the feasibility and efficacy of Separate stent placement in the palliative treatment of inoperable malignant gastroduodenal obstruction.Methods Thirty four consecutive patients with inoperable malignant gastroduoenal obstruction were treated with peroral placement of Separate stent. Gastroduodenal obstruction was caused by gastric ( n =11), pancreatic ( n =12), matastatic ( n =3), biliary duct ( n =6) or duodenal ( n =2) cancers. Separate outer partial covered stent overlapping with inner bare stent were placed coaxially under fluoroscopic guidance.Results The technical successful rate reached 97% (33 of 34) with no major complication. Symptoms of gastroduodenal obstruction relieved in 33 patients. The average score of food intake capacity improved from 3.8 to 1.2 after Separate stent placment. Stent migration and tumor ingrowth were not detected during the follow up period. Tumor overgrowth was confirmed in one patient and a second stent was placed to solve the problem.Conclusions Peroral placement of Separate stent is a feasible and effective treatment for patients with inoperable malignant gastroduodenal obstruction.
