Abstract
Purpose
Ventral hernias are a surgical challenge, often requiring detailed imaging for surgical planning. Computed tomography (CT) is widely used in preoperative assessment, with three-dimensional (3D) reconstructions increasingly applied in surgical fields. This study aims to assess whether 3D CT reconstructions improve surgical planning compared to conventional two-dimensional (2D) CT.
Methods
A cross-sectional survey was conducted from October 2024 to January 2025, enrolling 66 surgeons with diverse experience. Participants were randomized into two groups: one assessing a complex ventral hernia using conventional CT and the other using both 2D and 3D reconstructions. Data were collected through questionnaires based on the DECOMP criteria, surgeons’ perception of hernia characteristics, surgical planning, and treatment strategies. Statistical analyses, including Fisher’s exact test, Chi-square test, and ROC curve analysis, were performed to compare outcomes.
Results
No significant differences were found between the groups in the evaluation of the hernia, preoperative planning, or surgical approach. Surgeons predominantly relied on personal interpretation of CT scans rather than radiology reports. Notably, 3D reconstructions decreased the perception of hernia sac omental content (74.2% vs. 97.1%, p = 0.01). Furthermore, 3D visualization did not alter surgical decisions, including mesh selection, component separation, or preoperative techniques for loss of domain.
Conclusion
3D CT reconstructions do not impact the evaluation or surgical planning of complex ventral hernias compared to 2D CT. Although 3D imaging may enhance anatomical visualization, its clinical utility is unclear. Conventional 2D CT, when carefully analyzed, remains sufficient for surgical decision-making. Further research is needed to assess 3D imaging’s benefits.
