This comprehensive review explores the pivotal role of advanced clinical practitioners (ACPs) in gastroenterology care and the integration of phenomenological approaches in both practice and research domains. ACPs in gastroenterology play multifaceted roles encompassing clinical assessment, triage, diagnosis, treatment and patient management. By adopting a phenomenological approach in practice, ACPs can transcend traditional biomedical models, prioritise patients' lived experiences and provide personalised, holistic care. In research, phenomenological methods offer valuable insights into patients' subjective experiences, informing evidence-based practice and contributing to the advancement of gastroenterology care. Through illustrative examples and critical analysis, this review highlights the significance of integrating phenomenological approaches in enhancing patient outcomes and improving the quality of care in gastroenterology services.
