Summary
Three-dimensional (3D) virtual models improve colorectal surgery by enabling precise lesion localization. This pilot study demonstrated 100% accuracy in identifying neoplastic lesions using 3D models, enhancing surgical planning and outcomes.
Area of Science:
- Surgical Oncology
- Medical Imaging
- Computational Anatomy
Background:
- Colorectal surgery traditionally relies on 2D imaging, posing challenges for precise macroscopic localization of neoplastic lesions.
- Accurate localization of colon lesions is critical for successful surgical intervention and patient outcomes.
Purpose of the Study:
- To evaluate the clinical impact and accuracy of 3D virtual models in colorectal surgery for lesion localization.
- To compare the efficacy of 3D models versus traditional 2D imaging in surgical planning.
Main Methods:
- A prospective observational pilot study involving 14 patients undergoing colorectal surgery for neoplastic lesions.
- Acquisition of staging computed tomography (CT)/magnetic resonance imaging (MRI) scans and colonoscopy data to create 3D renderings.
- Comparison of lesion localization and procedural planning between surgeons using 2D images and those using 3D models, validated against intraoperative and histopathological findings.
Main Results:
- Lesion localization using 3D models achieved 100% accuracy.
- Conventional 2D CT scans failed to detect the lesion in two cases, necessitating reliance on colonoscopy.
- 3D model reconstruction demonstrated excellent concordance between estimated and actual lesion location, facilitating accurate surgical planning.
Conclusions:
- Three-dimensional virtual models significantly enhance the precision of lesion localization in colorectal surgery compared to traditional 2D imaging.
- The use of 3D models leads to improved surgical planning and potentially better patient outcomes.
- Further large-scale clinical studies are warranted to confirm these findings.
