Currently, the diagnosis of CD is predominantly dependent on endoscopic procedures and histopathological tissue analysis. Endoscopy is an invasive procedure, patient compliance is poor, and the results are subject to the operator's subjective judgment. Infliximab (IFX) and ustekinumab (UST) are two new biologics used for the treatment of CD, which are effective in reducing inflammatory markers. However, the correlation between blood metabolites and inflammatory markers has rarely been studied in the biologic agents employed in the management of CD, and their effects on metabolic processes remain inadequately understood. This study aimed to elucidate the effects of IFX and UST on the blood metabolites in patients with CD, investigate the correlations between metabolic variations and clinical indicators, and examine the relationship between the identified biomarkers and clinical efficacy.</p><p><strong>Methods: </strong>A total of 81 patients with CD who were receiving biologic therapy enrolled at week 16 between January 2022 and December 2023 (45 receiving IFX and 36 receiving UST) and 45 healthy controls were included.

However, gastroscopy and pathological examination are invasive, resource-dependent, and associated with low adherence, while conventional serological and imaging screening methods have limited sensitivity for early lesions. In recent years, artificial intelligence (AI), especially deep learning, has improved the efficiency and accuracy of real-time endoscopic detection, digital pathological recognition, non-contrast CT-based opportunistic screening, and multimodal diagnostic decision support. This review summarizes recent advances in AI-assisted technologies for gastric cancer diagnosis and, in response to the need for a clearer methodological and quantitative framework, compares representative models according to data modality, model architecture, dataset size, validation strategy, and reported diagnostic performance, including AUC, accuracy, sensitivity, specificity, precision/positive predictive value (PPV), and F1 score when available. We further discuss how data size, modality diversity, annotation granularity, class imbalance, and missing modalities influence model performance in real-world multicenter settings. Finally, we propose a structured multimodal AI-clinical decision support system (AI-CDSS) framework integrating CT imaging, endoscopic images and videos, whole-slide pathological images, serological indicators, molecular biomarkers, and clinical reports.

Historically, surgical intervention was considered a last-line option, reserved for patients in whom conservative or minimally invasive therapies had failed. However, growing evidence suggests that early surgical management may provide superior outcomes in terms of pain control and quality of life. The surgical management of CP encompasses a spectrum of procedures tailored to disease morphology and symptom profile. These include drainage procedures for patients with a dilated pancreatic duct, formal pancreatic resections for localized inflammatory masses or in cases with a high suspicion of malignancy, and combined resection-drainage techniques when ductal dilatation coexists with an inflammatory mass in the pancreatic head. A multidisciplinary evaluation is recommended for all patients prior to intervention to ensure optimal patient selection and individualized treatment planning.
