The Diagnostic Accuracy of Conventional Forceps Biopsy Compared to ESD.

ABSTRACT: conventional forceps biopsy (CFB) is the most popular way to screen for gastric epithelial neoplasia (GEN). Our study aimed to compare the diagnostic accuracy between conventional forceps biopsy and endoscopic submucosal dissection (ESD).105 patients diagnosed GEN finally undertook ESD in our hospital were enrolled. We retrospectively assessed the characteristics of pathological results of CFB and ESD.The overall pathologic concordance rate between the CFB and ESD specimens was 68.57%. 55 cases of CFB maintained low-grade intraepithelial neoplasia (LGIN) under ESD,18 cases (23.1%) diagnosis for high-grade intraepithelial neoplasia (HGIN), 5 cases (6.4%) diagnosis for cancer. Moreover, 10 cases of CFB maintained HGIN under ESD. Lesions with surface hyperemia (44.4% vs. 27.54%) or surface ulcer (57.14% vs.26.76%) were more likely to cancerate (P<0.05).endoscopic biopsy in the diagnosis of low-grade intraepithelial neoplasia, may exist or progression to high-grade intraepithelial neoplasia, some may have cancer, should take active treatment measures.

Project description:BackgroundHeart rhythm disorders, especially atrial fibrillation (AF), are increasing global health challenges. Conventional diagnostic tools for assessment of rhythm disorders suffer from limited availability, limited test duration time, and usability challenges. There is also a need for out-of-hospital investigation of arrhythmias. Therefore, the Norwegian ECG247 Smart Heart Sensor has been developed to simplify the assessment of heart rhythm disorders. The current study aimed to evaluate the diagnostic accuracy and usability of the ECG247 Smart Heart Sensor compared to conventional Holter monitors.MethodsParallel tests with ECG247 Smart Heart Sensor and a Holter monitor were performed in 151 consecutive patients referred for out-of-hospital long-term ECG recording at Sorlandet Hospital Arendal, Norway. All ECG data were automatically analysed by both systems and evaluated by hospital physicians. Participants were asked to complete a questionnaire scoring usability parameters after the test.ResultsA total of 150 patients (62% men, age 54 (±17) years) completed the study. The ECG quality from both monitors was considered satisfactory for rhythm analysis in all patients. AF was identified in 9 (6%) patients during the period with parallel tests. The diagnostic accuracy for automatic AF detection was 95% (95% CI 91-98) for the ECG247 Smart Heart Sensor and 81% (95% CI 74-87) for the Holter system. The proportion of false-positive AF was 4% in tests analysed by the ECG247 algorithm and 16% in tests analysed by the Holter algorithm. Other arrhythmias were absent/rare. The system usability score was significantly better for ECG247 Smart Heart Sensor compared to traditional Holter technology (score 87.4 vs. 67.5, p < 0.001).ConclusionsThe ECG247 Smart Heart Sensor showed at least comparable diagnostic accuracy for AF and improved usability compared to conventional Holter technology. ECG247 allows for prolonged monitoring and may improve detection of AF. This trial is registered with https://clinicaltrials.gov/ct2/show/NCT04700865.
