This method is widely accepted by many professionals as it can overcome many shortcomings of percutaneous liver biopsy and transjugular liver biopsy. The aim of the study is to obtain the adequate and optimal biopsy rate associated with EUS-LB.\u0000 Materials and Methods This is a retrospective observational study. Consecutive patients undergoing EUS-LB during the study period who were willing to consent were taken up for the study.\u0000 Results Total 91 patients were taken up for the study. Median age of study population was 44 years out of which 39 patients were males and 52 were females (42.9 and 57.1%). Adequate biopsy rate (according to European Association for the Study of Liver Disease criteria) and optimal biopsy rate (according to American Association for the Study of Liver Diseases criteria) were 89 (81/91) and 60.4% (55/91), respectively. Rate of conclusive diagnosis was 95.6% (86/91). The commonest diagnosis encountered was nonalcoholic steatohepatitis) (23, 25.3%), followed by autoimmune hepatitis (17, 18.7%). Additional diagnostic information was obtained by endosonography during EUS-LB in 21 patients (23.1%). Gallstone disease was found in four (4.8%) patients, chronic calcific pancreatitis in two (1.9%) patients, significant abdominal lymphadenopathy defined as lymph node more than 1.5 cm in five (5.8%) patients, and esophageal or gastric varices in ten (10.6%) patients. One case of self-limiting biopsy site ooze was seen in EUS-LB and the patient was having cirrhosis.\u0000 Conclusion This study showed a high diagnostic outcome and safety profile with EUS-LB technique. EUS-LB can achieve excellent histological yield when performed with optimal technique. Moreover, it is possible to obtain additional information during the procedure from diagnostic endosonography that is done as a part of EUS-LB.","PeriodicalId":43098,"journal":{"name":"Journal of Digestive Endoscopy","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2024-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141267851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the correlative factors of severity of air bubbles during colonoscopy in the large intestine are not established. Therefore, this study aimed to elucidate the correlative factors influencing the severity of air bubbles in the large intestine.\u0000 Materials and Methods A total of 314 examinees who underwent colonoscopy between August and September 2022 were enrolled (median age [range], 65 [18–88] years). Air bubbles were scored using the Colon Endoscopic Bubble Scale (CEBuS) and the clinical factors associated with the CEBuS scores, especially in the ileocecum, were analyzed.\u0000 Results In this study, 39.8% (125/314) of examinees harbored severe air bubbles in the ileocecum. Multiple linear regression analysis revealed that the CEBuS scores in the ileocecum were positively associated with the interval time from completion of bowel preparation to intubation of the cecum (p = 0.0016) and a history of cholecystectomy (p = 0.0198). Logistic regression analysis between no, mild, and moderate air bubbles group (n = 189) and severe air bubbles group (n = 125) also showed that severity was positively associated with the interval time from completion of bowel preparation to intubation of the cecum (p = 0.0332) and a history of cholecystectomy (p = 0.0095).\u0000 Conclusion Interval time and history of cholecystectomy were associated with severity of air bubbles in the large intestine after bowel preparation.","PeriodicalId":43098,"journal":{"name":"Journal of Digestive Endoscopy","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2024-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140752063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Colonoscopy has contributed significantly to reduction of incidence and mortality of CRC. Integration of artificial intelligence (AI) into colonoscopy practice has addressed the various shortcomings of screening colonoscopies. AI-assisted colonoscopy will help in real-time recognition of type of polyp with probable histology. This will not only save time but will also help to mitigate human errors. Computer-aided detection and computer-aided characterization are two applications of AI, which are being studied extensively with a goal of improvement of polyp and adenoma detection rates. Several studies are being conducted across the globe, which either involve simple decision-making algorithms or complex patterns through neural networks, which imitate the human brain. Most data are collected retrospectively and the research is limited to single-center studies, which might have bias. Therefore, the future research on AI in colonoscopy should aim to develop more sophisticated convolutional neural network and deep learning models that will help to standardize the practice and ensure the same degree of accuracy with all the colonoscopies, irrespective of experience of performing endoscopists. In this review, we will take a closer look at the current state of AI and its integration into the field of colonoscopy.","PeriodicalId":43098,"journal":{"name":"Journal of Digestive Endoscopy","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139005614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
