Introduction: The impact of device-assisted enteroscopy (DAE) on long-term rebleeding in patients with obscure gastrointestinal bleeding (OGIB) exhibiting detectable small-bowel lesions remains unclear. We investigated the long-term rebleeding rate and predictive factors for DAE in patients with OGIB. Method: Patients with OGIB with small bowel lesions detected through DAE were enrolled at three Korean tertiary hospitals. Predictive risk factors associated with rebleeding were analyzed using the Cox regression analysis. Results: From April 2008 to April 2021, 141 patients were enrolled, including 38 patients (27.0%) with rebleeding. The rebleeding rates at 1, 2, and 3 years were 25.0%, 29.6%, and 31.1%, respectively. The Cox regression analysis revealed that multiple small-bowel lesions (hazard ratio [HR]: 2.551, 95% confidence interval [CI]: 1.157–5.627, p = 0.020), the need for more than five packed red blood cells (RBC) transfusions (HR: 2.704, 95% CI: 1.412–5.181, p = 0.003), and ulcerative lesions (HR: 1.992, 95% CI: 1.037–3.826, p = 0.039) were positively associated with rebleeding. Therapeutic interventions for patients with detectable lesions, overt bleeding (vs. occult bleeding), comorbidities, and medications were not associated with rebleeding. Conclusion: More than 25% of patients with OGIB having detectable small-bowel lesions had rebleeding. Patients with multiple lesions, a requirement of more than five packed RBC transfusions, and ulcerative lesions were associated with a higher risk of rebleeding.
Purpose Endoscopic procedures can cause anxiety, which can lead to more uncomfortable, difficult, and incomplete procedures, in addition to greater use of sedative medication. Here, we investigate whether exposing patients to virtual reality (VR) prior to endoscopic procedures can reduce their anxiety levels. Materials and Methods Forty patients at Gangnam Severance Hospital were enrolled and divided into the VR group and the control group. Patients in the VR group were exposed to VR prior to their procedure to alleviate anxiety. The primary data outcomes were State-Trait Anxiety Inventory (STAI), pain score, satisfaction with sedation, and satisfaction with the procedure. Results The mean STAI-state and STAI-trait did not differ significantly between the control group and the VR group. While defining a high anxiety STAI score as ≥45 in an STAI-state, the proportion of patients with high anxiety at baseline was 35% and increased to 50% prior to the procedure in the control group. However, in the VR group, the proportion of patients with high anxiety at baseline was 60% and decreased to 50% prior to the procedure. The proportion changes of patients with high anxiety in the STAI-state exhibited a significant difference between the control and VR groups ( p =0.007). Furthermore, patients’ satisfaction with sedation was significantly greater in the VR group compared to the control group ( p =0.017). Conclusion VR exposure may relieve patients’ anxiety levels prior to endoscopic procedures, but further well-designed placebo-controlled studies are needed. VR, an inexpensive, easily available, and non-invasive method, also improved the satisfaction with sedation of endoscopic procedures.
In cases of progression despite chemotherapy, collecting gastric cancer (GC) tissues might be helpful for molecular biology research or the development of new target drugs for treating cases that are refractory to chemotherapy. Chemotherapy, however, may reduce or alter the distribution of GC tissue on the surface, making the detection of GC tissue during upper endoscopy challenging. Probe-based confocal laser endomicroscopy (pCLE) is a new technology that enables histological diagnosis by magnifying the mucous membrane to a microscopic level. Here, we evaluated whether pCLE could increase the yield of endoscopic biopsy for GC compared to white-light endoscopy (WLE) with magnifying narrow-band imaging (M-NBI) in GC patients receiving chemotherapy with its powerful imaging technique. Patients underwent WLE/M-NBI and pCLE for the detection of residual GC for the purpose of response evaluation or clinical trial registration. After WLE/M-NBI and pCLE, each residual GC lesion was biopsied for histological analysis. A total of 23 patients were enrolled between January 2018 and June 2020. Overall, pCLE showed significantly higher sensitivity and negative predictive value than WLE/M-NBI. The accuracy of pCLE was superior to that of WLE/M-NBI. Moreover, pCLE showed better predictive ability for residual GC than WLE/M-NBI, while WLE/M-NBI and pCLE showed inconsistent results. pCLE diagnosed residual GC more accurately than WLE/M-NBI, which resulted in an increased number of GC tissues collected during the endoscopic biopsy.
BackgroundNon-alcoholic fatty liver disease (NAFLD) and obesity are independently associated with increased risk for atherosclerotic cardiovascular disease (ASCVD), the leading cause of mortality in patients with NAFLD. Many NAFLD patients are lean, but their ASCVD risk compared to obese subjects with NAFLD is unclear.MethodsData from the 2008–2011 Korean National Health and Nutrition Examination Surveys database were analysed (n = 4,786). NAFLD was defined as a comprehensive NAFLD score of ≥40 or a liver fat score of ≥–0.640. ASCVD risk was evaluated using the American College of Cardiology/American Heart Association guidelines. A high probability of ASCVD was defined as an ASCVD risk of >10%.ResultsThe frequency of subjects without NAFLD, with obese NAFLD, and with lean NAFLD was 62.4% (n = 2,987), 26.6% (n = 1,274), and 11.0% (n = 525), respectively. Subjects with lean NAFLD had a significantly higher ASCVD score and prevalence of a high ASCVD risk (mean 15.6 ± 14.0 and 51.6%) than those with obese NAFLD and without NAFLD (mean 11.2 ± 11.4 and 39.8%; 7.9 ± 10.9 and 25.5%, all P < 0.001). Subjects with lean NAFLD and significant liver fibrosis showed a significantly higher odds ratio for a high risk for ASCVD than those with obese NAFLD with or without significant liver fibrosis (odds ratio = 2.60 vs. 1.93; P = 0.023).ConclusionsDespite a more favourable metabolic profile, subjects with lean NAFLD had a significantly higher ASCVD score and prevalence of high ASCVD risk than those with obese NAFLD. Similarly, lean subjects with significant liver fibrosis had a higher probability of ASCVD than obese subjects in the subpopulation with NAFLD.
