Aluminium phosphide-induced esophageal stricture palliation with polyflex stent.

A 21-year-old woman developed midesophageal stricture two weeks after ingestion of aluminium phosphide (AlP) tablets. Aluminium phosphide is a lethal protoplasmic toxin and is also the most common cause of suicidal poisoning in northern India. Upper gastrointestinal endoscopy (UGIE) showed a tight esophageal stricture 29 cm from the incisors with a circumferential ulcer. Dilatation up to 17 mm was done using Savary-Gilliard dilators. She had repeated dilatations three times at nearly two-week intervals. In view of the resistant stricture, a silicone Polyflex stent was placed across the stricture and removed after 3 months; there was no recurrence of stricture even after three months of follow-up. Patients with recurrent esophageal stricture and those with fistula may benefit from silicone expandable stents.
