Margin control in minutes before incision closing, with histology-grade confidence.

The Histolog Scanner is a digital microscopy scanner for ultra-fast confocal imaging of fresh excision. It reveals the morphology of the tissue at the subcellular level. In the treatment of cancer, the Histolog Scanner can help surgeons to visualize the excision’s margins.

Note: Currently for investigational use only

The Histolog Scanner has the potential to improve my confidence and ensure complete tumor removal during breast conserving surgery.

The Clinical Need

When surgically excising a tumor, the challenge for the surgeon is to remove all of the cancerous tissue while preserving as much as possible the healthy surrounding tissue. This is particularly true for breast conserving surgery and Mohs surgery in dermatology. To control the resection, it is specially prepared in thin slices for microscopy slide analysis in the pathology lab. The preparation of the slides takes time and it is done after the surgery. Depending on results, there may be a need to reoperate the patient for removing the remaining cancerous tissue. The patient care is improved when immediate margin assessment is made available during surgery.

 

The Histolog Scanner in your clinical practice

In light of this need, SamanTree Medical teams up with surgeons and pathologists to bring confocal microscopy in the operating room. As a result, the Histolog Scanner seamlessly integrates in the operating theater.

Once resected the full excision is simply dipped in a contrast agent and placed on a disposable dish over the imaging window. Within 1 minute the fresh excision is ready for imaging. There is no need for fixing, nor embedding, nor glass mounting of the excision. Then, within a few seconds, a digital image of the excision surface is displayed on a touch screen which allows to zoom and move around in the image. Surgeon can visualize suspicious lesion at a glance. Importantly, the excision remains intact for later final assessment.

The Histolog Scanner (v1.0 CE-mark, July 2016) has been used in renowned centers to demonstrate its imaging performance in both Mohs and breast cancer surgeries.
The release of the upgraded version to accommodate for whole lumpectomy is expected in September 2018.

  • 2017 Clinical study with Dr. C. Tausch from Brust Zentrum Zürich, one of the biggest breast center in Switzerland.
  • 2017 Collaboration with Dr. P.-M. Genolet (private gynaecologist surgeon) and Dr. Taminelli (pathologist, Medical Laboratory Director)
  • 2016 Clinical study with Prof. Dr. M. Möhrle, dermatologist renown in Mohs surgery based in Tübingen, Germany. University of Tübingen is recognized as one of the largest dermatological cancer center in Europe. Publication pending and related poster here.
  • 2016 Collaboration with Dr. O. Gaide, from CHUV (Centre Hospitalier Universitaire Vaudois), in Switzerland.

With the Histolog Scanner, the morphology of the freshly excised tissue is immediately visualized without the need for freezing or fixing.
