We report an 88-year-old man suffering from repetitive non-occlusive mesenteric ischemia (NOMI) accompanied with bradycardia and portal venous gas. He was admitted to hospital with acute onset epigastralgia and vomiting. Consciousness was clear, but he was pale and had a cold sweat. Vital signs were normal except for sinus bradycardia (HR 42). Abdominal CT revealed portal venous gas. Over 14 months, he had three recurrences of symptoms. We administered a muscarinic antagonist that improved the symptoms at the first and the second recurrence; however, at the third recurrence, the antagonist was ineffective, and the patient had increased portal venous gas, intestinal intramural gas, and hyperlacticacidemia. We performed emergent operation because of the possibility of bowel necrosis. Intraoperative laparoscopy revealed no obvious necrosis, and indocyanine green fluorography revealed no vascular insufficiency. These findings suggested the involvement of NOMI in acute mesenteric ischemia. After surgery, isosorbide dinitrate transdermal patch was administered to prevent NOMI by inhibiting mesenteric artery spasm. A 4-year follow-up revealed no recurrence of NOMI. We report the first case of repetitive NOMI accompanied with bradycardia and portal venous gas and its successful treatment.

The University of Tokyo Disability Services Office and the University of Tokyo Hospital have striven to advance the inclusion of individuals with disabilities and to encourage the co-production of research as well as mental health services with peer support workers. In convergence with these endeavors, the Center for Diversity in Medical Education and Research (CDMER) was founded in 2021. The Center aims to establish an environment and culture that facilitates the participation and success of medical professionals with disabilities. For this purpose, it is essential to integrate the perspective of the social model of disability into medical education and promote co-production in the medical field, which is among the most challenging areas that can realize co-production. The Center is involved in various educational and research activities, including managing educational programs for medical students and supporting student-led research.
