ObjectivesTo identify and classify submucosal tumors by building and validating a radiomics model with gastrointestinal endoscopic ultrasonography (EUS) images.MethodsA total of 144 patients diagnosed with submucosal tumors through gastrointestinal EUS were collected between January 2019 and October 2020. There are 1952 radiomic features extracted from each patient's EUS images. The statistical test and the customized least absolute shrinkage and selection operator regression were used for feature selection. Subsequently, an extremely randomized trees algorithm was utilized to construct a robust radiomics classification model specifically tailored for gastrointestinal EUS images. The performance of the model was measured by evaluating the area under the receiver operating characteristic curve.ResultsThe radiomics model comprised 30 selected features that showed good discrimination performance in the validation cohorts. During validation, the area under the receiver operating characteristic curve was calculated as 0.9203 and the mean value after 10‐fold cross‐validation was 0.9260, indicating excellent stability and calibration. These results confirm the clinical utility of the model.ConclusionsUtilizing the dataset provided curated from gastrointestinal EUS examinations at our collaborating hospital, we have developed a well‐performing radiomics model. It can be used for personalized and non‐invasive prediction of the type of submucosal tumors, providing physicians with aid for early treatment and management of tumor progression.

BACKGROUND Endoscopic resection of giant gastric leiomyomas, particularly in the fundus and cardia regions, is infrequently documented and presents a significant challenge for endoscopic surgery. CASE SUMMARY Herein, a case of a 59-year-old woman with a giant gastric leiomyoma was reported. The patient presented to the department of hepatological surgery with a complaint of right upper abdominal pain for one month and worsening for one week. The patient was diagnosed as gastric submucosal tumor (SMT), gallstone, and cholecystitis combined with computed tomography and gastroendoscopy prior to operation. Upon admission, following a multi-disciplinary treatment discussion, it was determined that the patient would undergo a laparoscopic cholecystectomy and endoscopic resection of gastric SMT. It took 3 hours to completely resect the lesion by Endoscopic submucosal excavation and endoscopic full-thickness resection, and about 3 hours to suture the wound and take out the lesion. The lesion, ginger-shaped and measuring 8 cm × 5 cm, led to transient peritonitis post-surgery. With no cardiac complications, the patient was discharged one week after surgery. CONCLUSION Endoscopic resection of a giant leiomyoma in the cardiac fundus is feasible and suitable for skilled endoscopists.
