    INTRODUCTION: Dunbar syndrome is a rare anatomical abnormality characterized by the extrinsic compression of the celiac trunk by the median arcuate ligament (MAL). Though it is rarely misdiagnosed, the clinical diagnosis may be difficult, especially after complex visceral surgery such as esophagectomy. PRESENTATION OF CASE: A 62-year-old male patient with a squamous cell carcinoma of the distal esophagus, placed under trimodal treatment (chemotherapy, radiotherapy followed by hybrid minimal invasive 2-field esophagectomy) presented with abdominal pain refractory to analgesics, anti-spasmodic, opioids, and neuronal celiac plexus ablation in the late post-operative period. He was diagnosed with extrinsic celiac trunk compression based on abdominal angiotomography findings. Retrospectively, similar images were found in conventional abdominal tomography at pre-operative staging, but this time, the patient had only dysphagia. After surgical treatment of MAL, the patient had total relief of pain and symptoms. DISCUSSION: Abdominal pain after complex surgical procedures is very frequent and its investigation is mandatory, even more after refractory clinical management. Dunbar syndrome is related to ambiguous abdominal pain. It is uncommon and its diagnosis with angiotomography is accessible. CONCLUSION: Vascular disorders should be investigated in cases of abdominal pain after complex surgical procedures. (C) 2020 The Authors.
