Intraoperative Assessment of Surgical Margins Using Confocal Microscopy in Comparison With Reference Extemporaneous Examination

"Surgical margins of tumor samples will be examined by conventional histopathology (H\&E) and confocal microscopy (Histolog® scanner, SamanTree Medical, Switzerland).~Depending on the histopathological result obtained between the two methods, the patient may benefit directly from early surgery if the experimental result confirms the presence of positive margins (excluding the learning curve).~A learning curve will be established over the first fifteen surgeries, enabling surgical teams to gain experience and systematize specimen flattening. This learning curve will also enable reference images to be produced. The procedure will be carried out by the surgeon and the pathologist in the operating room during this phase."
