INTRODUCTION: The bleeding source of hematochezia is unknown without performing colonoscopy. We sought to identify whether colonoscopy a risk-stratifying tool etiology and predict outcomes presenting symptoms can differentiate the etiologies in patients with hematochezia. METHODS: This multicenter retrospective cohort study conducted at 49 hospitals across Japan analyzed 10,342 admitted for outpatient-onset acute RESULTS: Patients were mostly elderly population, 29.5% had hemodynamic...
Abstract Background Direct and indirect clipping treatments are used worldwide to treat colonic diverticular bleeding (CDB), but their effectiveness has not been examined in multicenter studies with more than 100 cases. Objective We sought determine the short‐ long‐term of direct versus for CDB a nationwide cohort. Methods studied 1041 patients who underwent ( n = 360) or 681) at 49 hospitals across Japan (CODE BLUE‐J Study). Results Multivariate analysis adjusted age, sex, important...
There is a currently an unmet need for non-invasive methods to predict the risk of esophageal squamous cell carcinoma (ESCC). Previously, we found that specific soft palate morphologies are strongly associated with increased ESCC risk. However, there no artificial intelligence (AI) system utilizes oral images assessment. Here, evaluated three AI models and fine-tuning approaches regard their predictive power. Our dataset contained 539 cases, which were subdivided into 221 high-risk cases...
Introduction: Index colonoscopy findings can affect surveillance decisions that have an impact on the future risk of colorectal cancer (CRC). However, effectiveness in reducing CRC remains unclear. This study aimed to evaluate whether timing first affected incidence rates. Methods: We conducted a retrospective cohort at two community endoscopy clinics between 2005 and 2021, including 20,397 individuals. Based index colonoscopy, we categorized into four groups: advanced adenoma (AA), ≥3...
Currently, large, nationwide, long-term follow-up data on acute lower gastrointestinal bleeding (ALGIB) are scarce. We investigated risks of recurrence after hospital discharge for ALGIB using a large multicenter dataset.
The study aimed to identify prognostic factors for patients with acute lower gastrointestinal bleeding and develop a high-accuracy prediction tool. analysis included 8254 cases of hematochezia who were admitted urgently based on the judgment emergency physicians or gastroenterology consultants (from CODE BLUE J-study). Patients randomly assigned derivation cohort validation in 2:1 ratio using random number table. Assuming that present at time admission are involved mortality within 30 days...
Background and AimsWe aimed to determine the optimal timing of colonoscopy factors that benefit patients who undergo early for acute lower GI bleeding.MethodsWe identified 10,342 with hematochezia (CODE BLUE-J study) admitted 49 hospitals in Japan. Of these, 6270 underwent a within 120 hours were included this study. The inverse probability treatment weighting method was used adjust baseline characteristics among (≤24 hours, n = 4133), elective (24-48 1137), late (48-120 1000) colonoscopy....
Ligation therapy, including endoscopic detachable snare ligation (EDSL) and band (EBL), has emerged as an treatment for colonic diverticular bleeding (CDB); its comparative effectiveness risk of recurrent remain unclear, however. Our goal was to compare the outcomes EDSL EBL in treating CDB identify factors after therapy.We reviewed data 518 patients with who underwent (n = 77) or 441) a multicenter cohort study named Colonic Diverticular Bleeding Leaders Update Evidence From Multicenter...
Metastasis of gastrointestinal stromal tumor (GIST) into the central nervous system is extremely rare. We report a patient with synchronous GIST and brain metastasis. At disease onset, there was left hemiplegia ptosis right eyelids. Resection cytology reported as metastasis GIST. After positron emission tomography examination, another in small bowel discovered, which suggested associated intracranial Immunohistochemical analysis intestinal specimen obtained by double balloon endoscopy showed...
Abstract Background The value of endoscopy for acute lower GI bleeding (ALGIB) remains unclear, given few large cohort studies. We aim to provide detailed clinical data ALGIB management and identify patients at risk adverse outcomes based on endoscopic diagnosis. Methods conducted a multicenter, retrospective study, named CODE BLUE J-Study, in 49 hospitals throughout Japan studied 10,342 cases admitted outpatient-onset hematochezia. Results Cases were mostly elderly, with 29.5% hemodynamic...
Abstract Background and Aim While short long attachment caps are available for colonoscopy, it is unclear which type more appropriate stigmata of recent hemorrhage (SRH) identification in acute hematochezia. This study aimed to compare the performance versus hematochezia diagnoses outcomes. Methods We selected 6460 patients who underwent colonoscopy with from 10 342 cases CODE BLUE‐J study. performed propensity score matching (PSM) balance baseline characteristics between cap users. Then,...
Endoscopic submucosal resection with band ligation (ESMR-L) and endoscopic dissection (ESD) are both standard methods for rectal neuroendocrine tumors (NETs) <10 mm in size. However, there is no definitive consensus on which better. Here, we compared the efficacy of ESMR-L ESD small NETs.This was a multicenter retrospective cohort study including 205 patients NETs who underwent or ESD. Treatment outcomes were by univariate analysis, multivariate inverse probability treatment weighting (IPTW)...
The accurate sensitivity of amyloid deposition in extracardiac tissue (subcutaneous and gastrointestinal tract) has not been evaluated transthyretin amyloidosis cardiomyopathy (ATTR-CM) patients. This study aimed to evaluate the obtained endomyocardial biopsies.
Interdigitating dendritic cell sarcoma (IDCS) is an exceedingly rare neoplasm arising from the antigen-presenting cells of immune system [1] [2]. In general, IDCS aggressive tumor. The median overall duration survival 10 months [2] [3]. This first report magnifying endoscopic observation using narrow-band imaging.
Mediterranean fever (MEFV) gene mutations are responsible for familial (FMF) and associated with other inflammatory diseases. However, the effects of MEFV on intestinal Behçet's disease (BD) unknown. In this study, we investigated these clinical features in patients BD.MEFV analysis was performed 16 BD, 10 BD without lesions, 50 healthy controls. Clinical were retrospectively assessed.The rates controls 75%, 50%, 38%, respectively. Only 2 12 harboring (17%) controlled immunosuppressive...
症例は78歳女性.閉塞性黄疸及び十二指腸狭窄による嘔吐を主訴に来院.腹部造影CTでは,十二指腸と膵頭部の間に帯状の低吸収域を認め,十二指腸に接する膵内に10mm大の腫瘤性病変が認められた.十二指腸球部からのEUS走査では十二指腸に接する膵辺縁に低エコー腫瘤とこれに連続して,groove領域,十二指腸壁に不整に拡がる境界不明瞭な低エコー像を認めた.また十二指腸狭窄部からの内視鏡的生検にて腺癌が検出された.以上よりgroove領域に浸潤した膵癌と診断し亜全胃温存膵頭十二指腸切除術を施行した.病理組織学的には十二指腸に接する膵領域より発生しgroove領域及び十二指腸へ浸潤性増殖を示す25×20mmの膵癌(T3N0M0 pStageIII)であった.これまでgroove pancreatic carcinomaの報告においてEUS所見に言及した例は少なく貴重な症例と考え報告する.

<title>Abstract</title> Gastrointestinal endoscopy (GIE) performed by gastroenterologists is an important modality for early pharyngeal cancer detection. Human papillomavirus (HPV) one of the causes oropharyngeal squamous cell carcinoma (OPSCC). However, prevalence HPV-related OPSCC detected GIE currently unknown. We retrospectively analyzed 207 from 2018 to 2022, where HPV infection was diagnosed p16 immunohistochemistry. compared detection modalities and evaluated proportion lesions in...
