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.esMedicineHyperbaric oxygenCrohn's diseaseContext (archaeology)DiseaseAnastomosisInflammatory bowel diseaseSurgeryIntensive care medicineGastroenterologyletter
