Endoscopic Ultrasound Guided Drainage of a Post-Surgical Fluid Collection Using a Lumen-Apposing Metal Stent in a Patient With Crohn's Disease.

Patients with Crohn's disease (CD) are susceptible to postsurgical fluid collections and abscesses. Traditionally, these have been drained either percutaneously or surgically. Endoscopic ultrasound-guided drainage using a lumen apposing metal stent has not been used commonly for drainage of abdominal abscesses in patients with CD, given the concern of fistula formation because of transmural inflammation in patients with CD. We report a case of a large perigastric abscess that was drained through the stomach, using a lumen apposing metal stent with complete resolution of the abscess.
