About this trial

Laparoscopic cholecystectomy is a common surgical procedure, but it carries the potential for bile duct injury and other surgical risks. To provide visual assistance to surgeons during surgery and mitigate these risks, this research project aims to develop a real-time object recognition algorithm based on deep learning technology. This algorithm will label key anatomical structures in laparoscopic cholecystectomy videos, providing surgeons with immediate information on dangerous and safe areas.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patients aged 18 or above who are diagnosed by a doctor as needing laparoscopic cholecystectomy

Disqualifiers

Patients who did not undergo surgery at the original hospital and those whose videos were blurry were excluded.

Treatments tested in this trial

  • AI-assisted Intraoperative Anatomy Analysis

    Diagnostic test

    This is a prospective study on patients aged 18 years or more diagnosed with laparoscopic cholecystectomy. We will collect information such as laparoscopic cholecystectomy videos and procedure type, excluding patients who did not undergo surgery at the original hospital or whose videos were blurry.

Trial outcomes

Primary outcomes

1

Dice Similarity Coefficient

Dice Similarity Coefficient is a statistical measure of the similarity between two sets of data. In the context of image segmentation, it is used to quantify the spatial overlap between a predicted segmentation mask and its corresponding ground truth mask.

Time frame
3 years
2

Mean Intersection over Union

Mean Intersection over Union provides a measure of the overlap between the predicted segmentation and the ground truth, averaged across all classes present in the dataset.

Time frame
3 years
3

Global Accuracy

The proportion of correctly classified pixels out of the total number of pixels in the image.

Time frame
3 years

Secondary outcomes

1

Inference Latency

time taken by the algorithm to process a single video frame and generate the segmentation masks (inference latency), or equivalently, the number of frames processed per second

Time frame
3 years

Other outcomes

1

Class-Specific Precision and Recall for Critical Structures

Precision: The proportion of predicted pixels for a structure that are actually part of that structure Recall: The proportion of actual ground truth pixels for a structure that were correctly identified by the algorithm
