Intractable obstructive endobronchial granulation caused by surgical materials after sleeve resection for tracheal carcinoma.

Abstract

A 64-year-old woman underwent tracheal sleeve resection for adenocarcinoma. Thirteen months later minimal granuloma occurred at the anastomosis. Subsequently she had dyspnea from obstruction caused by the increasing size of the granuloma, which necessitated 4 repeated endobronchial debulking procedures and topical mitomycin C (MMC) application. However, the symptoms and granulation failed to resolve. Eventually, the granulation tissue and pledgeted sutures were removed from the anastomotic site using rigid bronchoscopy. Follow-up after 8 months showed no recurrence of symptoms, and the granuloma had resolved. Despite improvements in surgical suture material, removal of stitches should still be considered in the management of anastomotic obstruction caused by indolent and intractable granulation after tracheal resection or bronchoplasty.
