Abstract
Purpose
To evaluate the technical feasibility and safety of overtube-guided covered metallic stent placement as palliative treatment for patients with inoperable malignant gastric outlet obstructions.
Methods
To relieve the symptoms of severe nausea and recurrent vomiting in five patients with inoperable gastric cancer, we used an overtube (Long overtube; Sumitomo Bakelite, Tokyo, Japan) to place largediameter, self-expandable, covered esophageal Ultraflex stents (inner diameter 22–28 mm, length 10 or 12 cm; Boston Scientific, Watertown, MA, USA). Success was defined both technically and clinically.
Results
The stent placement was technically successful in all patients and resulted in improvement of symptoms in all five patients, four of whom were thereafter able to ingest solid food. The remaining patient, a 94-year-old man, was unable to ingest food because of dysmasesis. During the mean follow-up of 17 weeks, there was no stent reocclusion and no life-threatening complications developed.
Conclusions
The placement of a large diameter, self-expandable, covered esophageal stent using an overtube appears to be effective for the palliative treatment of malignant gastric outlet obstruction.
