Aluminum phosphide-induced esophageal strictures: a new cause of benign esophageal strictures.
Fifteen consecutive patients presenting with dysphagia due to aluminum phosphide (AP)-induced esophageal strictures were studied retrospectively to elucidate the natural history of AP-induced esophageal strictures and to evaluate the efficacy of bougie dilation. The median time lag between consumption of AP and occurrence of dysphagia was 3 weeks. All patients had a single stricture and could be dilated using a bougie dilator. Thirteen patients were relieved of dysphagia on a mean (SD) follow-up of 18 (7.3) months. Two patients had recalcitrant strictures and needed needle-knife incision of the stricture followed by balloon dilation. The strictures opened up well in both the patients and they were relieved of dysphagia. AP-induced esophageal stricture is a new cause of benign esophageal stricture. Most patients present with dysphagia around 3 weeks after consumption of AP tablets. A single esophageal stricture is found in these patients. Most strictures respond very well to bougie dilation. However, some of the strictures may be recalcitrant and may require needle-knife incision and balloon dilation.
