Abstract:Objective: We analyzed the demographic characteristics and clinical features of adult abdominal migraine(AM) to increase the understanding of this disease. Methods: We reported an adult case diagnosed as abdominal migraine in our clinic. Based on a literature search of the medical databases PubMed, Web of Science, LILACS, the Chinese online libraries of CNKI, VIP INFORMATION and WANFANG DATA, we carried out a systematic review of the adult AM case reports published from the databases inception to January 5th 2023. Results: The mean diagnosis age was 41.1 years old. The family and/or personal history of migraine was very common (91.3%) in 28 reviewed patients. Adults have a more precise and abundant description of the nature or region of pain compared with children. Additionally, 51.9% (14/27) of patients presented non-gastrointestinal symptoms. Finally, 13 patients received triptans, out of which 84.6% benefited from them. Conclusion: Despite a gradual increase in the reporting rate of adult AM, there is still inadequate knowledge of this disease. We need to take into account the possibility of AM in adults with recurrent unexplained abdominal pain. In particular, we must pay attention to non- gastrointestinal symptoms as well as migraine-related history during medical history taking. Triptans may be considered as a diagnostic test and experimental treatment in patients with unexplained abdominal pain after appropriate evaluation and exclusion of medication contraindications.
