Enhanced transanal surgery training through a 4K 3D surgical exoscope: a novel approach for transanal surgery.

PURPOSE

Recently, exoscope was introduced as a more ergonomic alternative to microscope, mainly in nerve and spinal surgery. Exoscope use in general surgery is still experimental and just few reports are present in literature. Here, we describe for the first time its application in transanal surgery, specifically during the transanal transection and single-stapled anastomosis in ileal-pouch anal anastomosis.

METHODS

After completing the proctectomy and pouch formation laparoscopically, two surgeons performed the transanal transection and single-stapled anastomosis using the vision provided by the ORBEYE™ exoscope system with a 3D 4K orbital camera and a 55-inches 3D screen. The transanal procedure was carried out with the surgeons looking at the 3D screen rather than at the operating field.

RESULTS

The system subjectively provided excellent operative view thanks to the magnification capacity and the high resolution. The ergonomics was improved compared to classical transanal surgery, allowing the operators and observers to have the same view in a comfortable position. In particular, the exoscope magnified vision allowed for clearer demonstration of techniques to trainees.

CONCLUSIONS

This is the first report on the intraoperative application of the ORBEYE™ surgical exoscope in transanal surgery. The magnified vision allowed precise movements and the system appeared potentially a ground-breaking tool for surgical training. The ability to project high-quality images to observers make it ideal for teaching complex transanal procedures. Further studies are encouraged to validate this approach into standard colorectal practice.
