Self-expandable metal stents (SEMS) to palliate symptoms of malignant gastric
outlet obstruction (GOO).
Methodology: This was a prospective non-randomized study. It was performed
at Jiangsu Province Hospital, Najing China. Duration was one year
from april 2015 to 2016. Patients with gastric outlet obstruction caused by unresectable
malignancy of stomach, pancreas and duodenum were included in
a consecutive manner. Stenting was done under direct endoscopic and fluroscopic
visualization and conscious sedation. Only uncovered SEMS were used.
We evaluated our technical success rate, Gastric Outlet Obstruction Scoring
System (GOOSS) score before and after stent placement, and complications.
Results: Total number of patients was 30. Self Expandable Metal Stents (SEMS)
were successfully placed in all patients. Thus, technical success rate was100%.
29 patients resumed oral intake without vomiting. Clinical success rate was
96.7%. There was significant improvement in GOOSS score with stenting (p
value<0.05). Only 2 (6.7%) patients had their stents blocked due to tumor
ingrowth later in the course of follow-up which was successfully managed by
Conclusion: Use of SEMS as a palliative modality for malignant GOO is a feasible,
safe and effective method.
