Application of Three-Dimensional Visualization Technology in Preoperative Planning of Complex Abdominal Wall Defect Repair and Reconstruction

Aim To prospectively study the role of three-dimensional visualization (3DV) technology in preoperative planning of complex abdominal wall defect repair and reconstruction. Methods 210 patients with complex abdominal wall defects who underwent reconstruction surgery were enrolled. Preoperative planning was performed by CT imaging (CT group) or 3DV technology (3DV group). Results The methods of repair and reconstruction of abdominal wall defects included single or double patch, three-layer bridging (mesh+greater omental flap+mesh), CST+mesh, CST+mesh+omental flap, mesh+tissue flap repair. There was no significant difference in the clinical cure rates of abdominal wall defect observed between the CT group and 3DV group (82.61% vs.91.30%, P > 0.05). The clinical cure rates of abdominal wall defect caused by primary and secondary abdominal wall tumors were 96.23% and 89.66% in the 3DV group, respectively, which were significantly higher than those in the CT imaging group (84.91% and 68.97%, both P < 0.05). Conclusion 3D visualization technology can accurately evaluate the indicators of complex abdominal wall defects before surgery, helping clinicians to make an improved individualized surgical planning.
