Infectious Abscess as Complication of Steroid Injection With Dilation of Refractory Upper Gastrointestinal Strictures.

Benign, refractory upper gastrointestinal strictures can be challenging to treat. Dilation combined with intralesional steroid injection is part of treatment algorithms. This intervention is typically well-tolerated, and few complications of this technique have been reported in the literature. We report 2 patients with infectious abscesses, 1 involving the neck and 1 involving the pylorus, as a complication of steroid injection and dilation of refractory strictures.
