Self-expanding metal stent for relieving the stricture after endoscopic injection for esophageal varices

Figure 1 Observing the retention in the esophageal cavity using an endoscope, and we should be alert to residual varices. A: The stricture was exposed under the endoscope; B: This is a semi covered self-expanding metal stent; C: The self-expanding metal stent was passed through the stricture by a hard wire guarding; D: We should be alert to the residual varices, when we were placing the self-expanding metal stent; E: The oral side of stent should be above and near to the stricture; F: The anal side of stent should be passed cardia.

Figure 2 The position of stent. A: After expanding, the oral side of stent was well; B: After expanding, the endoscope was passed through the stent; C: After expanding, the endoscope was passed through stent into the stomach to confirm that anus of stent being well.

Figure 3 Clamping the knot of stent and pull with forceps to adjust the self-expanding metal stent if the stent embedd into esophageal mucosa after placing. A: After placing for one month, the stent embedd into esophageal mucosa; B: The knot of stent was clamped and pulled with forceps to adjust the self-expanding metal stent; C: The stent was being adjusted with the forceps; D: After adjusting, the position of self-expanding metal stent was well.
