The ingestion of corrosives may lead to tight near-total strictures of the esophagus with concomitant involvement of the hypopharynx. This is an extremely challenging situation for the clinicians and there are limited treatment options for addressing such complex strictures.
The only viable management option for complex hypopharyngo-esophageal strictures is surgery. However, surgical interventions are associated with high morbidity and mortality. Moreover, patients may even be unfit for undergoing surgery due to extreme malnutrition. Because of these reasons, many patients ultimately succumb to their illness. The development of minimally invasive endoscopic techniques would be a highly desirable step to salvage this subset of patients.
In this study, we evaluated a novel flexible endoscopic technique for the management of tight near-total corrosive strictures of the esophagus with concomitant involvement of the hypopharynx.
Two patients with near-total hypopharyngo-esophageal strictures were managed by the novel technique, under conscious sedation. A flexible 0.025-inch guide-wire was passed across the stricture, followed by dilatation of the stricture with a 10F coaxial diathermy and balloon dilators. The residual eccentric stricture was electroincised by a novel approach, using a wire-guided sphincterotome.
Both patients were successfully managed on an OPD basis with the complete relief of symptoms and resolution of strictures on endoscopy and an esophagogram. No complication was seen during or after the procedure. In the follow-up, patients remained symptom-free, along with a significant improvement in the body mass index.
The complex hypopharyngo-esophageal strictures were successfully opened up with the novel flexible endoscopic technique, without any complications.
We report a novel minimally invasive flexible endoscopic technique for addressing the tight near-total hypopharyngo-esophageal strictures. The technique is relatively simple, safe and effective with a durable response. But larger studies are required to validate the efficacy and safety of the technique across different endoscopic set-ups.
