Abstract Background Visual inspection, lesion detection, and differentiation between malignant benign features are key aspects of an endoscopist’s role. The use machine learning for the recognition images has been increasingly adopted in clinical practice. This study aimed to establish convolutional neural network (CNN) models automatically classify gastric neoplasms based on endoscopic images. Methods Endoscopic white-light pathologically confirmed lesions were collected classified into...
Capsule endoscopy has revolutionized the management of small-bowel diseases owing to its convenience and noninvasiveness. is a common method for evaluation obscure gastrointestinal bleeding, Crohn's disease, tumors, polyposis syndrome. However, laborious reading process, oversight lesions, lack locomotion are major obstacles expanding application. Along with recent advances in artificial intelligence, several studies have reported promising performance convolutional neural network systems...
Classification of colorectal neoplasms during colonoscopic examination is important to avoid unnecessary endoscopic biopsy or resection. This study aimed develop and validate deep learning models that automatically classify lesions histologically on white-light colonoscopy images.
AIMTo elucidate the epidemiological characteristics and associated risk factors of perforated peptic ulcer (PPU). METHODSWe retrospectively reviewed medical records patients who were diagnosed with benign PPU from 2010 through 2015 at 6 Hallym university-affiliated hospitals. RESULTSA total 396 identified postoperative complication rate 9.1% mortality 0.8%.Among 174 (43.9%) examined for Helicobacter pylori (H.pylori ) infection, 78 (44.8%) positive H. 21 (12.1%) on non-steroidal...
Aim To compare the efficacy and safety between modified quadruple- bismuth-containing quadruple therapy as first-line eradication regimen for Helicobacter pylori infection.Methods This study was a multicenter, randomized-controlled, non-inferiority trial. Subjects endoscopically diagnosed with H. infection were randomly allocated to receive (rabeprazole 20 mg bid, amoxicillin 1 g metronidazole 500 tid, bismuth subcitrate 300 qid [elemental 480 mg]; PAMB) or qid, tetracycline qid; PBMT) 14...
The effect of non-alcoholic fatty liver disease (NAFLD) on the occurrences colorectal neoplasm (CRN) at surveillance colonoscopy is rarely evaluated. We retrospectively reviewed medical records 1,023 patients who had both index and a single institution. cumulative occurrence rates overall advanced CRN time were compared between with without NAFLD using propensity score matching analysis. In an analysis matched cohort 441 patients, 3 5 years after higher in subjects than those (9.1% vs. 5.0%...

A primary nonresponse to oral drugs against hepatitis B virus (HBV) is a generally accepted criterion for interrupting treatment. We investigated whether the concept of suggested by current American (AASLD) and European (EASL) guidelines appropriate treatment with entecavir (ETV). The study included 1,254 treatment-naïve patients who had pretreatment HBV DNA levels >2,000 IU/mL received ETV 0.5 mg/day over 6 months. "Primary nonresponse" was defined as <2 log drop in after months therapy...
Background: The authors previously developed deep-learning models for the prediction of colorectal polyp histology (advanced cancer, early cancer/high-grade dysplasia, tubular adenoma with or without low-grade non-neoplasm) from endoscopic images. While model achieved 67.3% internal-test accuracy and 79.2% external-test accuracy, development was labour-intensive required specialised programming expertise. Moreover, 240-image dataset included only three advanced eight cancers, so it difficult...
A significant issue in drug efficacy studies is animal study design. Here we hypothesize that when evaluating new or existing therapeutics for the treatment of cancer, location disease burden will influence efficacy. To this, Female NCr nude mice were inoculated with luciferase-positive human breast cancer cells (LCC6WT-luc) orthotopically (o.t.), intraperitoneally (i.p.) intracardiacly (i.c.) to create localized, ascites disseminated disease, respectively. Tumor development was monitored...
<b>Background/Aim</b>: Endoscopic retrograde cholangiopancreatography (ERCP) is typically performed in prone position. In cases of difficulty position, ERCP can be left lateral We aimed to evaluate the efficacy and safety position for compared with those position.<br><b>Patients Methods:</b> Between August 2015 March 2016, a total 62 patients native papilla who underwent were randomly assigned undergo procedure (<i>n</i> = 31) or 31). The outcomes procedures between two...
The introduction of device-assisted enteroscopy (DAE) in the beginning 21st century has revolutionized diagnosis and treatment diseases small intestine. In contrast to capsule endoscopy, other main diagnostic modality bowel diseases, DAE unique advantages observing region interest detail enabling tissue acquisition therapeutic intervention. As becomes an essential procedure daily clinical practice, there is increasing need for correct guidelines on when how perform it what technical factors...
Coronavirus disease 2019 (COVID-19), caused by the novel coronavirus, is threatening global health worldwide with unprecedented contagiousness and severity. The best strategy to overcome COVID-19 a vaccine. Various vaccines are currently being developed, mass vaccination in progress. Despite very encouraging clinical trial results of these vaccines, there insufficient information on safety efficacy for inflammatory bowel (IBD) patients facing various issues. After reviewing current evidence...
