Introduction: Dunbar syndrome consists in a rare vascular disorder characterized by extrinsic compression of the celiac artery. This mechanic compression results in symptoms related to intermittent mesenteric ischemia. The goal of treatment is to release celiac artery compression and to restore vessel patency. Here we report two cases treated in our Surgical Department over the last four years. Case Report: A young female of 28 years-old, L.P., and 57-year-old men, E.G., both affected by recurrent post-prandial diffuse abdominal pain, diarrhea and weight loss came to our observation. A complete abdominal evaluation associated to radiologic exams made the diagnosis of CAC syndrome. Both patients were referred to a 3D laparoscopic surgical treatment of CACS with release of the median arcuate ligament. Vessels patency was checked intra-operatively using ecolaparoscopy. Conclusion: Median arcuate ligament section is the treatment of choice in Dunbar Syndrome, a rare vascular syndrome caused by extrinsic compression of the celiac trunk by a lower-inserted muscular bridge that connects the two crura of the diaphragm and crosses over the abdominal aorta. Minimally invasive 3D laparoscopic approach is ideal to treat Dunbar syndrome for the high definition and magnification of the 3D visualization. We perform an intraoperative laparoscopic duplex ultrasound investigation in the initial phase of the operation and at the conclusion of the procedure to assess the effectiveness of the treatment.
