An Efficient Framework for Video Documentation of Bladder Lesions for Cystoscopy: A Proof-of-Concept Study - Beyond the Abstract
We designed a framework for visual documentation that utilized cystoscopy videos and screenshots taken during the procedure to document clinically significant lesions. Screenshots function as a communication medium between the surgeon and the framework that will curate lesion-specific video content. We then manually labeled according to case identification, date, lesion location, imaging modality, and pathology.
The framework used the screenshot to search for and extract a corresponding 10-seconds video clip. Each video clip included a one-second space holder with a QR barcode informing the video content. The success of the framework was measured by the secondary use of these short clips and the reduction of storage volume required for video materials. From 86 cases, the framework successfully generated 249 video clips from 230 screenshots, with 14 erroneous video clips from 8 screenshots excluded. The HIPAA-compliant barcodes provided information of video contents with a 100% data completeness.
As an application of our framework, we examined the feasibility of creating a cystoscopy atlas by presenting the video clips arranged by pathological diagnosis. To protect PHI and preserve HIPAA compliance, the QR barcode containing the source file information was replaced with a QR barcode including only the pathology information. A web-based educational gallery was curated with various diagnostic categories and annotated frame sequences. Compared with the unedited videos, the informative short video clips reduced the storage volume by 99.5%.
In conclusion, our framework expedites the generation of visual contents with surgeon's instruction for cystoscopy and potential incorporation of video data towards applications including clinical documentation, education, and research.
