Abstract Background Currently, medical therapy of Crohn’s disease (CD) can reduce the progression some forms structural bowel damage (SBD), but it does not prevent it. Once SBD has developed, is important to assess potential treatments reverse this damage. Aims To determine whether transmural healing (TH), assessed by intestinal ultrasonography (IUS), be achieved with treatment in CD patients compared those without. Methods A prospective, longitudinal, observational study was conducted...
Abstract Background In the colorectum, intramucosal carcinoma (IMC), like high-grade dysplasia (HGD), should be resected endoscopically. Aims We were interested to understand how real-world treatment of IMC cases compares management HGD and T1 colorectal cancer (CRC). Methods A multicenter retrospective cohort study was conducted. Through pathology databases, all patients diagnosed between 2010 2019 with HGD, or CRC identified. Pathology endoscopy reports verified for polyps. The primary...
Clinical implementation of the resect-and-discard strategy has been difficult because optical diagnosis is highly operator dependent. This prospective study aimed to evaluate a that not dependent.The evaluated uses anatomical polyp location classify colonic polyps into non-neoplastic or low risk neoplastic. All rectosigmoid diminutive were considered hyperplastic and all located proximally sigmoid colon Surveillance interval assignments based on these priori assumptions compared with those...
Abstract Background Standard colonoscopy practice requires removal and histological characterization of almost all detected small (< 10 mm) diminutive (≤ 5 colorectal polyps. This study aimed to test a simplified polyp-based resect discard (PBRD) strategy that assigns surveillance intervals based only on size number small/diminutive polyps, without the need for pathology examination. Methods A post hoc analysis was performed patients enrolled in prospective study. The primary outcome...
Abstract Background Optical diagnosis can be used as an alternative to pathology for the evaluation of colorectal polyps. There exist multiple classification systems that assist in performing optical diagnosis. Aims The aim this study was compare three different classifications (NICE, SANO and WASP) when using Optivista iScan image enhanced endoscopy (IEE). Methods included subjects between 45–80 years undergoing elective screening, surveillance, or diagnostic colonoscopy with IEE. Three...
Abstract Background Recent research findings have identified an association between proximal sessile serrated lesions (SSL) and a greater risk of advanced metachronous neoplasia, without significant impact distal SSL. Aims The principal aim this study was to assess the total neoplasia (T-MAN) at follow-up (fu) colonoscopy after detection hyperplastic polyps (HP), adenomas their combination initial colonoscopy. Methods Medical records for patients aged 45 74 who underwent colonoscopies in...
Abstract Background Very few studies have described the risk of unfavorable histologic features (UHFs), lymph node involvement (LNI), distant metastasis (DM) and metachronous advanced neoplasia (MAN) after detection colorectal intramucosal carcinoma (IMC). Aims This study aimed to determine UHFs, LNI, DM MAN in patients with IMC, compared high-grade dysplasia (HGD) or T1 cancer (CRC). Methods A retrospective cohort was conducted. Through a pathology database search, we identified all...

Abstract Background Image enhanced endoscopy (IEE) allows for real-time optical diagnosis of colorectal polyps in order to replace histopathology. A novel classification system (SIMPLE classification) has recently been developed when using the Pentax Optivista IEE platform. Aims The aim this study was evaluate SIMPLE polyp a prospective clinical study. Methods Patients undergoing screening, diagnostic or surveillance colonoscopies were enrolled All 1-10mm found underwent with either iScan...
Abstract Background and study aims A novel endoscopic optical diagnosis classification system (SIMPLE) has recently been developed. This aimed to evaluate the SIMPLE in a clinical cohort. Patients methods All diminutive small colorectal polyps found cohort of individuals undergoing screening, diagnostic, or surveillance colonoscopies underwent using image-enhanced endoscopy (IEE) classification. The primary outcome was agreement intervals determined by compared with pathology-based results...
Abstract Background Submucosal injection (SI) is used for standard polypectomies or during complex endoscopic interventions. SI helps to facilitate resection and prevent complications such as bleeding perforation. Aims We were interested evaluate endoscopists practice patterns of using routine polypectomy endotherapeutic procedures. Methods An online survey the Google Form application was distributed through medical societies. Survey domains included training characteristics participating...
Abstract Background Replacing histopathology evaluation of diminutive polyps with optical polyp diagnosis is considered a cost-effective approach. However, the widespread use limited due to concerns about making incorrect diagnoses and requirements training, credentialing auditing performance. Aims This prospective study aimed evaluate simplified resect discard strategy that not operator dependent. Methods The evaluated uses anatomical location classify colon into non-neoplastic or low-risk...
(1) The aim of the present study was to describe endoscopic and histopathological findings in esophagus, stomach, duodenum patients with Crohn’s disease. (2) Methods: This a cross-sectional that included receiving treatment from inflammatory bowel disease outpatient clinic. Esophagogastroduodenoscopies biopsies stomach proximal were performed. Presence Helicobacter pylori bacteria assessed by Giemsa staining. (3) Results: We 58 patients. Erosive esophagitis identified 25 (43.1%), gastritis...
