BACKGROUND: To non-invasively identify incisional hernia repair implanted synthetic meshes with MRI, and also focusing on the evaluation of postsurgical complications such as adhesions. METHODS: A total of 43 patients underwent either laparoscopic intraperitoneal onlay-mesh or open abdominal wall repair using preperitoneal layers. The patients were examined using a true-fast-imaging-with-steady-state-precession (trueFISP)-sequence in transverse/sagittal orientation with a section-by-section dynamic depiction of induced visceral slide. A 9-segment-abdominal-map was used to document the adhesion location/type. The MR-images were analysed regarding hernia relapse, layer-morphology, rectus-abdominis muscle-condition, and abdominal wall mobility. In 12 patients pre- and postsurgery-MRI was performed. RESULTS: Time range between surgery and examination was 6-36 months. In all laparoscopy-patients the meshes were identified. For open surgery the mesh was not visualized in 20, but was seen in 6 cases. A total of 11 cases showed a recurrent hernia. Seventy intraabdominal adhesions were detected. Fifteen patients had restricted mobility. 20 patients showed an rectus-abdominis-muscle-asymmetry. Comparing pre- and post-op-MRI, 6 out of 8 patients with open repair showed thick scar-plaques. Three patients with open repair had new adhesion-formations postoperatively. CONCLUSION: Functional cine MRI is suitable for follow-up studies in patients after hernia repair to detect and evaluate the implanted meshes. Typical complications like intestinal adhesions and abdominal wall dysmotility can be assessed as well.
