Gauze detection and segmentation in laparoscopic liver surgery: a multi-center study.

ABSTRACT:

Background

Surgical gauze is commonly used in laparoscopic procedures. However, due to its small size, limited visibility to the naked eye, and subtle tactile presence, gauze can easily be overlooked during surgery.

Purpose

To support surgeons in detecting gauze, reduce the risk of omission, and enhance surgical safety and efficiency, we developed a deep learning framework designed to identify gauze in laparoscopic liver surgeries.

Methods

In total, 33 laparoscopic liver surgery videos were collected from 2 hospitals and used as internal and external datasets. Deep learning models were trained on individual video frames to detect and segment gauze, with each frame containing one or more gauze objects. To better evaluate model performance, we introduced a quantitative
