A case of delayed perforation following stent placement for malignant gastric outlet obstruction

88 Background: Self-expandable metallic stent (SEMS) placement is widely used for relieving the obstructive symptoms of malignant gastric outlet obstruction (MGOO). The aims were to evaluate the efficacy and safety of multiple gastroduodenal stent placement by stent in stent technique and identify predictive factors about stent patency. Methods: We retrospectively analyzed data from 170 patients with GOO receiving SEMS by stent in stent technique from July 2006 to July 2018. Among them, 90 patients had been treated with gastroduodenal SEMS placement for MGOO. Technical and clinical success rates were evaluated. And, clinical outcomes with predictors of stent patency were also analyzed. Results: Among the subjects, 34.4% were treated with secondary SEMS placement, and 9.7% were treated with third SEMS placement because of the previous stent dysfunction. The median stent patency time was 15.7 weeks (range 0-89) in the first SEMS, 10.4 weeks (range 0-44) in the second SEMS, and 11.3 weeks (range 1-29) in the third SEMS. The technical and clinical success rate were 100% and 97.8% in the first SEMS, 100% and 90.3% in the second SEMS, 100% and 100% in the third SEMS. In multivariable analysis, the first SEMS placement of covered type including Comvi stent was correlated with prolonged stent patency (OR 4.549, P = 0.001). And both chemotherapy after the first SEMS placement (OR 8.248, P = 0.006) and chemotherapy after the second SEMS placement (OR 7.467, P = 0.003) were correlated with prolonged stent patency. Serious complications such as gastrointestinal hemorrhage or perforation did not occur in any patient. Conclusions: Secondary and third gastroduodenal SEMS placement by stent in stent technique is a safe and effective treatment for the first stent dysfunction in MGOO. The stent placement of covered type and chemotherapy after stent placement is the predictor of stent patency.

Duodenal Stent

Introduction Placement of a duodenal or pyloric stent is a recognised palliative procedure for symptomatic relief of malignant gastric outlet obstruction. This procedure can be associated with significant complications, reinterventions and poor long-term relief of obstructive symptoms. However, there may be a faster return to diet and shorter hospital stay in comparison to other palliative procedures (eg gastrojejunostomy). The aim of this study was to determine the safety and efficacy of duodenal stenting in our regional district general hospital in comparison to that of larger tertiary centres. Materials and methods All patients with gastric outlet obstruction who had duodenal stent placement attempted in our region between 1 August 2013 and 31 July 2018 were identified by retrospective analysis of prospectively maintained coding databases and medical notes. Patient demographics, safety outcomes and efficacy outcomes were then extracted. Results were interpreted with respect to data from best available published evidence from larger tertiary centres. Results Of 43 duodenal stent insertion attempts, 84% had a successful return to diet, 18% underwent reintervention, 18% suffered adverse events, mean length of stay post-intervention was 8.6 days and mean survival post-intervention was 132 days. Conclusions Patients with malignant gastric outlet obstruction in whom duodenal stent placement was attempted had similar outcomes to published data from larger tertiary centres. Duodenal stent placement remains an acceptable treatment option for these patients in our region.
