Predictors of outcomes in patients undergoing covered and uncovered self-expandable metal stent placement for malignant gastric outlet obstruction: a multicenter study

Covered versus uncovered metal stents for malignant gastric outlet obstruction: Systematic review and meta‐analysis

“…S2A,B, respectively). Raw GOOSS score after gastroduodenal SEMS placement was available in seven studies . Weighted rates of the GOOSS score ≥2 after the procedure were not different between the groups (Fig.…”

“…In one RCT, covered SEMS were placed fluoroscopically alone as a protocol . One retrospective study included 15 patients with Billroth‐II anastomosis (11%), and another one included 18 patients with anastomotic obstruction (7.1%) . In two retrospective studies, both partially and fully covered types were used as covered SEMS …”

“…As secondary analyses, we evaluated causes of SEMS dysfunction based on 13 studies (Fig. ) . Compared with uncovered SEMS, covered SEMS were associated with a lower risk of stent occlusion (summary RR, 0.44; 95% CI, 0.28–0.68; P heterogeneity = 0.020, I 2 = 50%), but with a higher risk of stent migration (summary RR, 4.28; 95% CI, 2.89–6.34; P heterogeneity = 0.55, I 2 = 0%).…”

“…We evaluated adverse events associated with gastroduodenal SEMS based on 12 studies (Fig. ) . One study did not describe group‐specific rates of adverse events .…”

Covered duodenal self‐expandable metal stents prolong biliary stent patency in double stenting: The largest series of bilioduodenal obstruction

“…Historically, these malignant obstructions were treated by surgical gastroenterostomy combined with choledochojejunostomy . Endoscopic stenting using self‐expandable metal stents (SEMSs) is an effective and minimally invasive treatment in cases of duodenal obstruction and for palliation of biliary obstruction . In recent years, biliary and duodenal stenting (DS; double stenting) has been used to treat combined biliary and duodenal obstructions .…”
