Area of Science:

Neuropathology
Digital Pathology
Surgical Pathology

Background:

Intraoperative frozen section (FS) diagnosis is critical for surgical decision-making.
Telepathology offers remote consultation and diagnosis capabilities.
Integrating telepathology into neurosurgical workflows requires evaluation of its efficiency and accuracy.

Purpose of the Study:

To evaluate the diagnostic accuracy and turnaround time of a telepathology system for intraoperative frozen section diagnoses in neurosurgery.
To assess the reliability and technical challenges associated with implementing telepathology in a clinical setting.

Main Methods:

A telepathology system connected a neurosurgical department with a pathology department for 343 intraoperative frozen section cases between 2002 and 2005.

Each case involved gross examination, smear preparation, and frozen section slide.

Diagnoses were rendered remotely by an expert neuropathologist.

Main Results:

The average diagnosis time was 26.1 minutes, with 83% of cases diagnosed within 15-40 minutes.
System reliability was 100%, with diagnostic accuracy reaching 97.9% after excluding sampling errors.
Telemicroscopy was significantly slower than light microscopy, but technical software issues caused minimal delays.

Conclusions:

Telepathology is a reliable and accurate method for intraoperative frozen section diagnosis in neurosurgery.
The system significantly reduces diagnosis time, aiding surgical decision-making.
Despite slower telemicroscopy, telepathology demonstrates high diagnostic yield and system reliability.
