Diagnostic laparoscopy for early detection of acute mesenteric ischaemia in patients with aortic dissection

Introduction: Recognition of acute mesenteric ischaemia (AMesI) in patients with aortic dissection (AoD) may be a challenge and exploratory laparotomy is often performed. Methods: We retrospectively analysed our experience with the use of diagnostic laparoscopy (DL) for the early detection of AMesI in patients with AoD, either undergoing medical treatment or after open/endovascular interventions. Results: Between 2004 and 2011, 202 consecutive AoDs were treated in our centre (71 acute type A AoD; 131 acute and chronic type B AoD). Among the 17 (8.4%) patients in which AMesI was suspected, nine (52.9%) were selected for DL. Three DLs were performed during medical treatment of patients with acute type B AoD, six after treatment of AoD (both surgical and endovascular). Three second-look DLs were also performed. Eight DLs were negative, three showed AMesI and the patients underwent successful emergent revascularisation. One DL was not conclusive and laparotomy was required. Among the eight patients not submitted to DL, one case of bowel infarction was recorded. Conclusions: In our series DL was feasible and safe. The low invasiveness and repeatability were the main advantages. Although additional experience is mandatory, DL seems a promising technique for the detection of AMesI in patients with AoD. © 2012 European Society for Vascular Surgery. Published by Elsevier Ltd.
