1. Preoperative Prediction of Subtype and Artificial Intelligence-Driven Endomicroscopy Detection of Advanced Neoplasia in Intraductal Papillary Mucinous Neoplasms.
PMID:日期:2026-01-01Non-gastric subtype of branch duct (BD)-intraductal papillary mucinous neoplasms (IPMNs) are associated with high-grade dysplasia/invasive adenocarcinoma (HGD/IC) and disease progression. We evaluated preoperative prediction of gastric vs. non-gastric BD-IPMN subtypes and assessed a needle-based confocal laser endomicroscopy-guided artificial intelligence algorithm () for detecting HGD/IC in pathologist-reclassified BD-IPMNs. Participants with resected BD-IPMNs were enrolled from prospective studies (2015-2024). : lesions were reclassified by subtype and dysplasia grade through blinded pathologist review, with discordant cases receiving MUC immunostaining and consensus review. : using this reclassified pathology data, preoperative clinical and morphological features were analyzed to predict BD-IPMN subtypes. performance in detecting HGD/IC within reclassified gastric and non-gastric BD-IPMNs was evaluated using preoperative endomicroscopy videos. Among 63 resected BD-IPMNs (mean diameter=35.0±10.1 mm), 38% were classified as HGD/IC. The interobserver agreement among pathologists for subtype classification was moderate (k=0.52; 95%CI: 0.27-0.77). Multivariable analysis or preoperative variables revealed Kyoto high-risk stigmata (aOR=11.568, p=0.007), unifocal lesions (aOR=8.354, p=0.041), and lower BMI (aOR=1.37, p=0.04) predicted non-gastric subtype. The algorithm using presurgical endomicroscopy imaging showed comparable sensitivity for detecting HGD/IC in non-gastric and gastric IPMN subtypes (83% vs. 82%, p=0.92), but significantly higher specificity (100% vs. 44%, p=0.06) and accuracy (87% vs. 53%, p<0.02) in the non-gastric subtype. Moderate interobserver variability in BD-IPMN subtype classification among pathologists highlights the need for immunohistochemistry and consensus review in challenging cases. Preoperative clinical variables can predict non-gastric subtype which is associated with less favorable prognosis. shows improved performance in detecting HGD/IC in non-gastric BD-IPMNs, where accurate risk stratification is particularly important due to higher risk of progression.

2. Artificial Intelligence Advances Digital Pathomics for Confocal Endomicroscopy Diagnosis of Pancreatic Cysts.
PMID:日期:2025-05-22Endoscopic ultrasound-guided needle-based confocal laser endomicroscopy (nCLE) provides real-time optical biopsies enabling diagnosis and risk stratification of intraductal papillary mucinous neoplasms (IPMNs). However, the clinical implementation of Endoscopic ultrasound-nCLE is hindered by time-consuming image review and interobserver variability. We aimed to optimize artificial intelligence (AI) models to accurately detect diagnostic structures to address these gaps. Participants with definitive IPMN diagnoses were selected from prospective studies (2015-2023). Two observers labeled endomicroscopy images used to develop AI models to detect informative segments. Performance was assessed using area under the curve, sensitivity, specificity, and accuracy. In 66 endomicroscopy videos of IPMNs, 291,045 frames were analyzed, with 15.5% showing papillary or vascular structures and 84.5% lacking structures. Four classification (pattern recognition) and segmentation (image division) models were tested to evaluate binary detection outcomes (papillae vs other) and ternary detection outcomes (papillae, vascularity, and nonstructure). The classification model DINOv2-ViT-G outperformed all others for the binary outcome, achieving an area under the curve of 0.942, sensitivity of 80.6%, specificity of 90.6%, and accuracy of 89.3%. For the ternary outcome, only classification models were used because labeling areas for segmentation models to detect vascularity was impractical. DINOv2-ViT-G similarly demonstrated the best performance, with sensitivities for detecting papillae, vascularity, and nonstructure of 81.7%, 82.0%, and 80.5%, respectively. The DINOv2-ViT-G model reduced nCLE video duration to 1.85 minutes of high-yield, structure-containing segments, saving 4.27 minutes (70%) per IPMN case ( < 0.001). Optimized AI models for structure identification enhance the clinical utility of nCLE by generating high-yield diagnostic segments, ensuring consistent and accurate interpretation, reducing manual effort, and enabling the development of fully autonomous systems in the future.

3. AN ELECTRONIC MEDICAL RECORD PREDICTION MODEL TO IDENTIFY INADEQUATE BOWEL PREPARATION IN PATIENTS AT OUTPATIENT COLONOSCOPY.
PMID:日期:2023-12-26Inadequate bowel preparation during colonoscopy is associated with decreased adenoma detection, increased costs, and patient procedural risks. This study aimed to develop a prediction model for identifying patients at high risk of inadequate bowel preparation for potential clinical integration into the EMR. A retrospective study was conducted using outpatient screening/surveillance colonoscopies at the University of North Carolina (UNC) from 2017 to 2022. Data were extracted from the EMRs of and , including demographic, socioeconomic, and clinical variables. Logistic regression, LASSO regression, and gradient boosting machine (GBM) models were evaluated and validated in a held-out testing set. The dataset included 23,456 colonoscopies, of which 6.25% had inadequate bowel preparation. The reduced LASSO regression model demonstrated an area under the curve (AUC) of 0.65 [95% CI 0.63-0.67] in the held-out testing set. The relative risk of inadequate bowel prep in the high-risk group determined by the model was 2.42 (95% CI 2.07-2.82), compared to patients identified as low risk. The model calibration in the testing set revealed that among patients categorized as having 0-11%, 11-22%, and 22-33% predicted risk of inadequate prep, the respective proportions of patients with inadequate prep were 5.5%, 19.3%, and 33.3%. Using the reduced LASSO model, a rudimentary code for a potential Epic FHIR application called was developed. This study developed a prediction model for inadequate bowel preparation with the potential to integrate into the EMR for clinical use and optimize bowel preparation to improve patient care.

5. Development and Validation of an Automated, Real-time Adenoma Detection Rate and Colonoscopy Quality Metrics Calculator.
PMID:日期:2023-07-28High-quality colonoscopy reduces the risk of death from colorectal cancer. The adenoma detection rate (ADR) is the principal measure of colonoscopy quality but is onerous to calculate. We report the development of a fully automated platform for calculation of the ADR and other key colonoscopy quality indicators without the need for manual data entry. Endoscopy and pathology reports from 6 centers were collected over a 3-month period and collated using a novel data transfer interface. Text-based classification parameters were developed to identify average-risk screening colonoscopies, adenomatous pathology, cecal intubation, and withdrawal time. Automated quality metrics calculators based on these classifications were built into a web-based reporting platform, and the resulting quality metrics were benchmarked against those produced through a manual record review. Confirmation of the calculator's performance was performed in a validation cohort with data collected over a 1-month period, 6 months after the initial study. The study included 3809 colonoscopies (mean age 56.1 ± 6.40 years, 53.7% female, 38 endoscopists). The automated calculator yielded an ADR of 45.1% compared with 44.3% on manual review. Correct classification of ADR-qualifying screening colonoscopies was achieved with high predictive value, with a sensitivity of 0.918 and specificity of 1.0. The cecal intubation rate was 95.8%, and the average withdrawal time was 10:05 minutes. We demonstrate the feasibility and performance of a colonoscopy quality reporting platform capable of calculating the ADR and other key metrics using novel, fully automated pathology report integration and a text query-based classification accessible in a wide range of practice settings.

7. Reducing disparities and achieving health equity in colorectal cancer screening.
PMID:日期:2023-03-01Increases in colorectal cancer screening are linked to the declining incidence of the disease over the past three decades. These favorable trends, however, are not observed in marginalized racial and ethnic populations with disproportionately lower rates of screening, higher disease incidence, and increased mortality despite advances in health technology and policy. This review describes the differences in screening uptake and test selection amongst racial and ethnic groups, discusses known obstacles and facilitators that impact screening, and highlights existing frameworks developed to achieve health equity in colorectal cancer screening.

8. Closure of Mucosal Defects Using Endoscopic Suturing Following Endoscopic Submucosal Dissection: A Single-Center Experience.
PMID:日期:2022-11-12Endoscopic submucosal dissection (ESD) is a therapeutic technique for en-bloc resection of both large (>20 mm) and smaller, complex gastrointestinal neoplasms. ESD has a higher success rate of en-bloc resection and a lower rate of local recurrence compared to endoscopic mucosal resection (EMR). Removal of lesions via ESD can leave large mucosal defects, raising unique challenges leading to adverse events. We aimed to determine clinical outcomes including delayed bleeding, perforation and hospitalization in patients undergoing endoscopic suturing following ESD. Single-center retrospective study of a prospectively collected database of consecutive adult patients who underwent ESD with mucosal defect closure using endoscopic suturing. Primary outcomes were adverse events, specifically, delayed bleeding or perforation. Secondary outcomes included need for hospitalization and suturing complications. 55 patients (mean age: 67 years) were included with a mean lesion size of 27.4 mm ± 15. Defect closure occurred in the esophagus (6), gastroesophageal junction (2), stomach (30), cecum (2), sigmoid colon (2) and rectum (13). A mean of 1.8 ± 1.0 sutures were required for defect closure. Hospital admission rates were 14% (8/55) with an average length of stay 2 days (range: 1-3 days). Intra-procedure perforation occurred in two patients and both were successfully treated with endoscopic suturing. There was one case of delayed bleeding and no cases of delayed perforation or suturing complications. The use of endoscopic suturing following ESD is a safe and clinically reliable method to close mucosal defects. This approach is associated with minimal adverse events and need for hospitalization. Larger studies are needed to further validate these findings.

10. Yield of Post-Acute Diverticulitis Colonoscopy for Ruling Out Colorectal Cancer.
PMID:日期:2022-04-18Colonoscopy is recommended post-acute diverticulitis (AD) to exclude underlying adenocarcinoma (CRC). However, post-AD colonoscopy utility remains controversial. We aimed to examine yield of post-AD colonoscopy in our majority-Hispanic patient population. Patients undergoing post-AD colonoscopy between 11/1/2015-7/31/2021 were identified from a prospectively maintained endoscopic database. AD cases without computed tomography confirmation were excluded. Pertinent data, including complicated vs uncomplicated AD, fecal immunochemical test (FIT) result post-AD/pre-colonoscopy, and number/type/location of non-advanced adenomas, advanced adenomas, and CRC, were abstracted. Analyses were conducted using two-sample Wilcoxon rank-sum and Fisher's exact tests. 208 patients were included, of whom 62.0% had uncomplicated AD. Median age was 53, 54.3% were female, and 77.4% were Hispanic. Ninety non-advanced adenomas were detected in 45 patients (21.6%), in addition to advanced adenoma in eight patients (3.8%). Two patients (1.0%) had CRC, both of whom had complicated AD in the same location seen on imaging, and one of whom was FIT+ (the other had not undergone FIT). Patients with uncomplicated versus complicated AD had similarly low rates of advanced adenomas (4.7% vs. 2.5%, p=0.713). FIT data were available in 51 patients and positive in three (5.9%); non-advanced adenomas were found in all three FIT+ patients. No FIT- patient had an advanced adenoma or CRC. Colonoscopy post-AD is generally low yield, with CRC being rare and found only in those with complicated AD. Colonoscopy post-complicated AD appears advisable, whereas less invasive testing (e.g. FIT) may be considered post-uncomplicated AD to inform the need for colonoscopy.
