Colonoscopy is the gold standard for screening cancer and precancerous lesions in large intestine. Recently, remarkable advances artificial intelligence (AI) have led to development of various computer-aided detection (CADe) systems colonoscopy. This study aimed evaluate usefulness AI colonoscopy using CAD-EYEⓇ (Fujifilm, Tokyo, Japan) calculate adenoma miss rate (AMR). randomized, open-label, single-center, tandem was conducted at Fukuoka University Chikushi Hospital from February 2022...
Background and Aim Endoscopic balloon dilation ( EBD ) is an alternative to surgery for small bowel strictures of patients with C rohn's disease CD ). However, little known about the long‐term efficacy . The aim present study was clarify outcome in Methods Subjects comprised 65 who underwent intestinal were followed up at least 6 months. All subjects had obstructive symptoms as a result strictures. Short‐term success defined technical disappearance symptoms. short‐term rate , its safety...
Artificial intelligence (AI) systems have shown favorable performance in the detection of esophageal squamous cell carcinoma (ESCC). However, previous studies were limited by quality their validation methods. In this study, we evaluated an AI system with videos simulating situations which ESCC has been overlooked.We used 17,336 images from 1376 superficial ESCCs and 1461 196 noncancerous normal esophagi to construct system. To record videos, endoscope was passed through esophagus at a...
Intestinal complications of stenosis or fistula may occur during the course Crohn's disease (CD), and surgery is performed in a fair number patients. The risk factors for initial Japanese hospital-based cohort CD patients were evaluated.This study was single-center, retrospective, study. subjects 520 who underwent inpatient outpatient treatment at our hospital, had definitive diagnosis CD, no previous surgery. Three parameters investigated: (i) cumulative incidence fistula; (ii) rate each...
The Japan Esophageal Society created a working committee group consisting of 11 expert endoscopists and 2 pathologists with expertise in Barrett's esophagus (BE) esophageal adenocarcinoma. developed consensus-based classification for the diagnosis superficial BE-related neoplasms using magnifying endoscopy. has three characteristics: simplified, an easily understood by incorporating diagnostic criteria early gastric cancer, including white zone demarcation line, presence modified flat...
Aim: We assessed the long‐term outcome of infliximab (IFX) therapy in patients with Crohn's disease (CD) and investigated efficacy concomitant endoscopic balloon dilation (EBD) for intestinal stricture during treatment. Methods: The effectiveness maintenance IFX was retrospectively evaluated 185 CD a single center (median observation period 24 months). without immunomodulators (IMM) enteral nutrition (EN), as well cumulative surgery‐free rates, were compared. EBD obstructive symptoms...
Abstract Background Accurate evaluation of tumor invasion depth is essential to determine the appropriate treatment strategy for patients with superficial esophageal cancer. The pretreatment diagnosis currently relies on magnifying endoscopic classification established by Japan Esophageal Society (JES). However, diagnostic accuracy tumors involving muscularis mucosa (MM) or those invading upper third submucosal layer (SM1), which correspond Type B2 vessels in JES classification, remains...
The aim of the present study was to endoscopically evaluate ileal mucosal healing during maintenance therapy with infliximab in order investigate clinical significance endoscopic examination lesions Crohn's disease patients.This retrospectively analyzed 54 patients who mainly had active ulcers ileum on endoscopy at baseline were responsive induction and received therapy. Mucosal defined as no ulcer or only scar. At time follow-up after starting infliximab, score, healing, remission...
Head and neck cancers, especially in hypopharynx oropharynx, are often detected at advanced stage with poor prognosis. Narrow band imaging enables detection of superficial cancers transoral surgery is performed curative intent. However, pathological evaluation real-world safety clinical outcomes have not been clearly understood. The aim this nationwide multicenter study was to investigate the efficacy for head cancer. We collected patients squamous cell carcinoma who were treated by from 27...
In this study, survival and cause of death were investigated in patients with Crohn's disease (CD) at a tertiary referral center.A database was created based on the medical records 1108 CD who had history visiting our hospital to investigate background characteristics, cumulative rates from diagnosis, causes death, standardized mortality ratio (SMR) for each death. A follow-up questionnaire survey followed up inadequately also conducted. The rate diagnosis determined using life table method...
Abstract Background Currently, no classification system using magnification endoscopy for the diagnosis of superficial Barrett’s esophagus (BE)-related neoplasia has been widely accepted. This nationwide multicenter study aimed to validate diagnostic accuracy and reproducibility system, including flowchart developed by Japan Esophageal Society—Barrett’s working group (JES-BE) esophagus-related neoplasms. Methods The JES-BE acquired high-definition narrow-band imaging (HM-NBI) images...
Background/Aims: Helicobacter pylori infection-negative gastric cancer (HPNGC) has not been systematically investigated in consecutive patients. Hence, this study aimed to investigate the clinicopathological and endoscopic features of HPNGC.Methods: This single-center retrospective selected participants from patients with who were treated at Fukuoka University Chikushi Hospital between January 2013 December 2021. Only diagnosed HPNGC enrolled, their analyzed detail.Results: The prevalence...
<b>Background and study aims:</b> The authors have successfully demonstrated that the white opaque substance (WOS) identified in gastric epithelial neoplasms is an accumulation of minute lipid droplets on neoplasm. It not known whether originate from externally ingested lipids (typically foods). purpose this was to investigate oral ingestion foods containing emulsified fats increases density WOS neoplasms. <b>Patients methods:</b> We examined 92 neoplastic lesions 89 patients. patients were...
Recent innovations in prophylactic treatment with steroids have overcome the issue of esophageal stricture after endoscopic submucosal dissection (ESD), except entire circumferential squamous cell carcinoma (EC-ESCC). Current Japanese guidelines weakly recommend performing ESD for clinical epithelial/lamina propria EC-ESCC a longitudinal extension <50 mm upon implementing against stricture. However, accurate indications remain unknown, and strategies differ among institutions. The aim this...
Multiple white and flat elevated lesions (MWFL) that develop from the gastric corpus to fornix may be strongly associated with oral antacid intake. Therefore, this study aimed determine association between occurrence of MWFL proton pump inhibitor (PPI) intake clarify endoscopic clinicopathological characteristics MWFL.
Recent reports have focused on the development of secondary amyloidosis (AMY) as a complication Crohn's disease (CD). The present study was carried out to investigate frequency AMY CD, its clinical and endoscopic features, importance duodenal biopsy in detecting this disease.This involved 408 patients diagnosed with CD who were endoscopically histologically examined at our hospital. At follow up, we analyzed incidence complications, features methods diagnose AMY.The 2.5% (10/408). type time...
Decreased trough levels of infliximab (TLI) and antibodies to (ATI) are associated with loss response (LOR) in Crohn's disease. Two prospective studies were conducted determine whether TLI or ATI better correlates LOR (Study 1), could become a predictor mucosal healing (MH) 2).Study 1 was 108 patients, including those remission compare discriminating the 2 conditions based on receiver operating characteristic (ROC) curve analyses. Study involved 35 patients who evaluated endoscopically.In 1,...
Patients with incomplete gastric intestinal metaplasia (GIM) have a higher risk of cancer (GC) than those complete GIM. We aimed to clarify whether micromucosal patterns GIM in magnifying endoscopy narrow-band imaging (M-NBI) were useful for diagnosis GIM.We enrolled patients history endoscopic resection GC or detailed inspection suspicious definite GC. The antrum greater curvature and corpus lesser regions interest. Areas findings light blue crest and/or white opaque substance (WOS) defined...
Background/Aims: Image-enhanced endoscopy can detect superficial oro-hypopharyngeal squamous cell carcinoma; however, reliable of the pharyngeal region is challenging. Endoscopy under general anesthesia during transoral surgery occasionally reveals multiple synchronous lesions that remained undetected on preoperative endoscopy. Therefore, we aimed to determine lesion detection capability for carcinoma.Methods: This retrospective study included 63 patients who underwent oropharyngeal...
<b><i>Background/Aims:</i></b> In Japan, aphthous-type Crohn's disease (type A CD) is thought to represent an early phase of (CD), and diagnosis type CD possible in the diagnostic criteria for Japan.
