Abstract
Objective To establish an artificial intelligence-based surgical selection system utilizing deep learning to as-sist in the decision-making process for lumbar endoscopic surgery.Methods General data of 1,110 patients who underwent per-cutaneous transforaminal endoscopic discectomy,804 patients who underwent percutaneous interlaminar endoscopic discectomy,923 patients who underwent mobile microendoscopic discectomy and 623 patients who underwent unilateral biportal endoscopic in Tianjin Hospital from January 2018 to June 2023 were included in the study.Clinical outcomes were assessed using the visual ana-logue scale(VAS)for leg and back pain,the Oswestry disability index(ODI),and MacNab criteria both before surgery and 12 months postoperatively.Using a random number table method,patients were divided into a training dataset(2,768 cases)and a test dataset(692 cases)at a ratio of 4∶1.Patient clinical symptoms,physical signs,and multi-modal imaging data were input into a deep learning model.This model was structured into three main modules:intervertebral disc detection,surgical necessity identifi-cation,and surgical recommendation.The final surgical method was determined using a convolutional neural network incorporat-ing U-Net for segmentation and ResNet for classification.The accuracy and recall rates of each module were evaluated using the test dataset.Results Compared to preoperative values,all patients showed significant improvements at the 12-month postopera-tive follow-up.For patients who underwent percutaneous transforaminal endoscopic discectomy,percutaneous interlaminar endo-scopic discectomy,mobile microendoscopic discectomy,and unilateral biportal endoscopic surgery,the VAS scores for leg pain de-creased from 7.69±0.80,7.82±0.88,7.62±0.69,and 7.56±1.00 preoperatively to 1.44±1.09,1.35±0.82,1.51±1.08,and 1.43±0.91 postoperatively.Similarly,the VAS scores for back pain decreased from 5.73±0.83,6.17±0.99,6.11±0.88,and 6.46±0.95 to 0.93±0.75,1.01±0.67,1.40±0.72,and 1.27±0.70,respectively.Additionally,the ODI significantly decreased from 39.91%±4.50%,40.05%±8.05%,47.08%±9.50%,and 44.43%±4.71%preoperatively to 5.77%±2.22%,6.05%±2.31%,8.51%±2.16%,and 9.51%±3.70%postoperatively,with all differences being statistically significant(P<0.05).The excellent rate according to the MacNab criteria was 93.12%(3,222/3,460).In the deep learning model,the multi-modal data of 2,768 patients were input in the training set for deep learning to form a surgical identification and operation recommendation system,and the preoperative data of 692 patients were input in the test set to compare with the final operation method.In the intervertebral disc location module,the accuracy of location and designation of the five lumbar intervertebral discs was 97.1%(672/692).In the module of intervertebral disc need for surgery,the accuracy was 94.8%(3,280/3,460)and the recall rate was 91.9%(636/692).As for patients,the accuracy rate was 91.9%(636/692).In the operation recommendation module,the accuracy rate of operation recommendation based on inter-vertebral disc was 89.5%(569/636),and the accuracy rate of surgical recommendation based on patient was 82.2%(569/692).Conclusion In this study,an artificial intelligent surgical procedures selection system based on deep learning was established,which could effectively integrate relevant data and accurately guide the selection of lumbar endoscopic surgery.
