Life-threatening bowel complications in adults with Duchenne muscular dystrophy: a case series

Duchenne muscular dystrophy is a progressive muscle wasting disease caused by pathogenic variants in DMD. Gastrointestinal involvement is increasingly recognised in older patients and can manifest as life-threatening bowel dysmotility. We describe a series of adults with Duchenne muscular dystrophy who developed either severe colonic pseudo-obstruction or sigmoid volvulus requiring urgent assessment and intervention. The presentations varied in their clinical picture and outcomes, but together highlight the complexity of managing gastrointestinal complications in this cohort of patients. Key considerations include pre-existing cardiorespiratory compromise and the increased risk associated with surgery and general anaesthesia. We also outline a role for home parenteral nutrition in the long-term management of associated bowel dysmotility. (c) 2023 Elsevier B.V. All rights reserved.
