Tight near-total corrosive strictures of the proximal esophagus with concomitant involvement of the hypopharynx: Flexible endoscopic management using a novel technique

Figure 3 Near-total stricture in case 1 and its endoscopic management. A: The esophagogram after dilatation in case 1 showed a residual eccentric stricture, suggestive of persistent adhesions in the post-cricoid space and left piriform sinus; B-D: Serial endoscopic images of electroincision procedure in case 1, as the wire-guided sphincterotome was progressively moving towards the left pharyngeal wall after cutting the adhesions in the post-cricoid space and left piriform sinus; E: After electro-incision, a dilatation was given with the dilating balloon placed in the left piriform sinus; F: Follow-up esophagogram showing the completely opened-up stricture along its entire length.
