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...
Background The rebleeding risks and outcomes of endoscopic treatment for acute lower gastrointestinal bleeding (ALGIB) may differ depending on the location, type, etiology stigmata recent hemorrhage (SRH) but have yet to be fully investigated. We aimed identify high risk SRH propose an optimal strategy. Methods retrospectively analyzed 2699 ALGIB patients with at 49 hospitals (CODE BLUE-J Study), whom 88.6 % received treatment. Results 30-day rates untreated significantly differed among...
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...
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,...
This study evaluated the risk of metachronous colorectal cancer (CRC) after resection index (first) rectal in patients with Lynch syndrome (LS).
In Japanese patients with familial adenomatous polyposis (FAP), colectomy tends to be postponed or avoided.
Stigmata of recent hemorrhage (SRH) directly indicate a need for endoscopic therapy in acute lower gastrointestinal bleeding (LGIB). Colonoscopy would be prioritized patients with highly suspected SRH, but the predictors colonic SRH remain unclear. We aimed to construct predictive model efficient detection using nationwide cohort.We retrospectively analyzed 8360 admitted through hospital emergency departments LGIB CODE BLUE-J Study (49 hospitals throughout Japan). All underwent inpatient...
Self-expandable metallic stents (SEMSs) are used for the management of malignant colorectal obstruction. A patient who underwent colonic uncovered SEMS insertion extraluminal stenosis in splenic flexure transverse colon due to advanced gastric cancer is herein reported. The presented with a fracture 494 days after insertion. Although various complications stenting have previously been reported, details fractures SEMSs not yet Because improvement prognosis patients undergo palliative leads...
A 59-year-old woman presented with a chief complaint of melena. She had no abdominal findings, such as tenderness or tapping pain. Laboratory tests revealed white blood cell count 5,300 cells/μL and C-reactive protein level 0.07 mg/dL. Inflammation anemia (hemoglobin 12.4 g/dL) were denied. Contrast-enhanced computed tomography (CT) multiple duodenal diverticula air surrounding descending diverticulum. Based on these diverticular perforation (DDP) was suspected. Oral food intake stopped,...
In patients with APC-associated polyposis, the prevalence of upper gastrointestinal tumors and relationship between these Helicobacter pylori infection have not been clarified in detail. The present study aimed to clarify features lesions polyposis.Consecutive polyposis who underwent esophagogastroduodenoscopy 2004 2018 were recruited.In total, 36 enrolled. types tumor observed fundic gland 28 (77.8%), gastric adenoma 15 (41.7%), duodenal 27 (75.0%) periampullary 20 (55.6%). phenotype was...
Colonoscopy surveillance reduces the incidence of colorectal cancer through detection and endoscopic removal adenomas. Current guidelines recommend that patients with Lynch syndrome should have colonoscopy every 1-2 years starting at age 20-25. However, insufficient data are available to evaluate quality safety for nationwide in Japan.Patients (n = 309) from 13 institutions who underwent one or more procedures were enrolled this retrospective analysis. completion rate, colonoscopy-related...
