Self-expandable metal stents for malignant gastric outlet obstruction: A pooled analysis of prospective literature

Figure 1 Endoscopic view of a gastric antrum adenocarcinoma involving the pylorus and causing obstructive symptoms (A) for which an uncovered WallFlex stent (Boston Scientific) was placed (B). Fluoroscopic view shows the fully deployed stent across the pylorus (C) with good passage of contrast to the duodenum (D).

Figure 2 Endoscopic view of an adenocarcinoma of the distal stomach invading the duodenal bulb causing a gastric outlet obstruction (A) for which an uncovered WallFlex stent (Boston Scientific) was placed (B). Fluoroscopic view shows the fully deployed stent in the duodenal bulb (C) with good passage of contrast to the distal duodenum (D).

Figure 4 Endoscopic view of an ulcerative, obstructing gastrointestinal stromal tumor of the peri-ampullary region of the duodenum (A) for which an uncovered WallFlex stent (Boston Scientific) was placed (B). Fluoroscopic view shows the fully deployed duodenal stent overlapping the previously placed biliary SEMS (C).
