Abstract
Focusing on esophageal cancer, this dissertation conducted a meta-analysis to evaluate the general performance of Artificial Intelligence (AI) methods on the diagnosis of Esophageal Squamous Cell Carcinoma (ESCC) in endoscopic images and videos. The results indicated the qualified performance of AI methods in image-based ESCC diagnosis. However, there is still room for improvement of AI methods on video-based ESCC diagnosis. Then a pipeline was proposed and implemented in the University Hospital of Cologne to collect and preprocess Robotic Assisted Minimally Invasive Esophagectomy (RAMIE) video data for data analysis and AI modeling research. Over 200 cases were successfully enrolled and collected by the pipeline in the past three years. For AI modeling research, a Relation Laparoscopic Cholecystectomy Surgical Object Detector (Relation-LCSOD) model was developed to enhance the reliability and accuracy of AI methods in surgical object detection. A series of comparative experiments were performed to validate and test the performance of the proposed model based on two public datasets. The comparison results with baseline models on two datasets demonstrate significant performance improvements of the proposed models, especially for anatomically relevant objects detection. The proposed model can utilize position relation information among surgical objects and effectively reduce redundant bounding boxes. The AI modeling research in this dissertation can promote the trust integration of AI into esophageal cancer research and support AI applications in more clinical practice in the future.
