Treatment with hyperbaric oxygen in a Crohn's disease patient.

Despite advances in the treatment of inflammatory bowel disease, particularly with biological therapies and new small molecules, a significant gap still exists in achieving persistent remission from a symptomatic, biomarker, and endoscopic perspective. In this context, hyperbaric oxygen therapy (HBOT) is considered as a therapeutic strategy. This approach has also been suggested for managing ischemic ulcers located at anastomotic sites. In this clinical case, we describe the clinical and endoscopic evolution of a challenging-to-manage Crohn's disease (CD) patient with an ischemic ulcer at the ileo-rectal anastomosis who underwent HBOT.
