RESUMO

Background and study aim Endocytoscopy (ECS) is used in the in vivo microscopic inspection of microstructural mucosal features and enables endoscopists to assess the histological severity of ulcerative colitis (UC). The aim of this study was to assess histological healing in UC patients by using ECS. Patients and methods A total of 64 patients in clinical and endoscopic remission who underwent ECS were selected. The correlation between the ECS score and Geboes score at the rectum was evaluated in patients with a Mayo endoscopic score (MES) of 0. The diagnostic accuracy of the ECS score for histological remission (Geboes score ≤ 2) was also assessed. Results The ECS score ranged from 0 to 5 in patients with endoscopic remission on conventional white-light images (MES of 0). The agreement between histological remission regarding the ECS score and the Geboes score had a κ value of 0.72, and the ECS score showed high accuracy for histological remission, with a sensitivity of 0.77, a specificity of 0.97, and a diagnostic accuracy of 0.86. Conclusion ECS can be used to assess histological healing in patients with UC without the need for biopsy specimens.

RESUMO

BACKGROUND/AIMS: Chinese herbal medicine Qing-Dai (also known as indigo naturalis) has been used to treat various inflammatory conditions. However, not much has been studied about the use of oral Qing-Dai in the treatment for ulcerative colitis (UC) patients. Studies exploring alternative treatments for UC are of considerable interest. In this study, we aimed at prospectively evaluating the safety and efficacy of Qing-Dai for UC patients. METHODS: The open-label, prospective pilot study was conducted at Keio University Hospital. A total of 20 patients with moderate UC activity were enrolled. Oral Qing-Dai in capsule form was taken twice a day (daily dose, 2 g) for 8 weeks. RESULTS: At week 8, the rates of clinical response, clinical remission, and mucosal healing were 72, 33, and 61%, respectively. The clinical and endoscopic scores, CRP levels, and fecal occult blood results were also significantly improved. We observed 2 patients with mild liver dysfunction; 1 patient discontinued due to infectious colitis and 1 patient discontinued due to mild nausea. CONCLUSION: This is the first prospective study indicating that oral Qing-Dai is effective for inducing remission in patients with moderate UC activity and can be tolerated. Thus, Qing-Dai may be considered an alternative treatment for patients, although further investigation is warranted.

RESUMO

INTRODUCTION: Mucosal healing has emerged as a desirable treatment goal in clinical practice for patients with Crohn's disease (CD). The aim of this study was to assess the relationship between endoscopic activity and the long-term prognosis of CD using simple endoscopic score for Crohn's disease (SESCD) and Rutgeerts' score. METHODS: We conducted a cohort study in clinical practice at a single center. Among CD patients who underwent colonoscopy between July 2008 and June 2011 at our hospital, 131 patients with clinical remission were selected, and the patients were divided into 2 groups: a non-surgical group (n = 84) and a surgical group (n = 47). The primary endpoint of this study was to assess the associations between variables and clinical relapse after endoscopic procedures. The cut-off levels of SESCD or Rutgeerts' score for the prediction of relapse were also assessed in patients with clinical remission. RESULTS: In the non-surgical group, SESCD and C-reactive protein at baseline were significantly higher in patients who had clinical recurrence than in patients who maintained remission. A factor of SESCD ≤2 was independently associated with sustained remission, even in patients with clinical remission. In the surgical group, patients with Rutgeerts' scores ≤1 had significantly prolonged clinical remission compared to patients with Rutgeerts' scores ≥3. CONCLUSION: A cut-off value of SESCD ≤2 and a Rutgeerts' score ≤1 enabled the prediction of long-term prognosis. These cut-off values could be used in clinical trials of endoscopic remission from the point of view of the clinical outcomes of CD.

RESUMO

We aimed to identify quality indicator for esophagogastroduodenoscopy for detecting upper gastrointestinal (UGI) cancer. Data from 43,526 consecutive health checkups from August 2012 to January 2022 were retrospectively collected. The study ultimately analyzed 42,387 examinations by 12 endoscopists who performed more than 1000 examinations, including all cancers detected. These endoscopists were classified either into fast/slow group based on their mean examination time for a normal finding of esophagogastroduodenoscopy during their first year of the examination, or small/large group based on number of endoscopic images, respectively. The association between UGI cancer detection rate and examination time or the number of images was analyzed, using 5 minutes or 50 images as cutoff values. The detection rate of overall (8 pharyngeal, 39 esophageal, 69 gastric) cancers in the fast, slow, small, and large groups were 0.17%, 0.32%, 0.21%, and 0.31%, respectively. On multivariable analysis, endoscopists in the fast group or the small group were less likely to detect overall UGI cancer (OR: 0.596, 95% CI: 0.373-0.952, P = .030; OR: 0.652, 95% CI: 0.434-0.979, P = .039). Additionally, repeated endoscopy within 2 years had a higher overall cancer detection rate, compared with repeated screening after 2 years. In a sub-analysis, a significant negative relationship was found between the detection rate of gastric cancer and the number of gastric images < 35 (OR: 0.305, 95% CI: 0.189-0.492, P = .000). There was also a negative correlation trend between the detection rate of pharyngeal and esophageal cancers and the number of esophageal images < 11 (OR: 0.395, 95% CI: 0.156-1.001, P = .050). The optimal number of images and screening 2-year interval are considered useful quality indicators for detecting UGI cancer. This study also suggests that a total of 50 images, or 35 images of the stomach are suitable for detecting UGI cancer, or gastric cancer, during screening endoscopy.

RESUMO

BACKGROUND AND AIM: In Japan, patient acceptance of bowel preparation methods before colonoscopy remains unknown. This study was conducted to evaluate the patient acceptance of sodium phosphate (NaP) tablets and polyethylene glycol solution (PEG) with sodium picosulfate. METHODS: One hundred patients were randomized into one of the following two groups: the NaP tablet first-use group or the PEG with sodium picosulfate first-use group in a crossover design trial. Patient acceptance and incidence of adverse events were evaluated using a questionnaire. Colon-cleansing effectiveness was also evaluated. RESULTS: Patients' overall impressions of the preparations were significantly different between the NaP tablet (77.9%, 67/86) and PEG with sodium picosulfate (60.5%, 52/86; P = 0.001). Nausea incidence as an adverse event was significantly different between the two regimens (P = 0.03). Colon-cleansing effectiveness was not significantly different between the two regimens. CONCLUSIONS: The results of this crossover study showed that patient acceptance was similar to those previously reported in a parallel-group comparison. In Japanese patients, preference for and acceptance of NaP tablets was significantly higher than that for PEG with sodium picosulfate solution.

RESUMO

BACKGROUND: This cross-sectional study aims to investigate the association between subclinical atherosclerosis and metabolic dysfunction-associated fatty liver disease (MAFLD) or non-alcoholic fatty liver disease (NAFLD), and a synergistic effect of diabetes mellitus (DM) and MAFLD on subclinical atherosclerosis. METHODS: Of 977 subjects who underwent health checkups with coronary artery calcification (CAC), carotid intima-media thickness, and brachial-ankle pulse wave velocity (ba-PWV), 890 were included in this study. They were classified as MAFLD, NAFLD, or Neither-FLD, and MAFLD was further categorized into three groups by three metabolic disorders (obesity, lean with metabolic dysregulation, DM), according to its new definition: Obesity-MAFLD, Lean-MAFLD and DM-MAFLD. RESULTS: In a multivariable analysis, MAFLD and NAFLD were significantly associated with subclinical atherosclerosis, except for an association between ba-PWV and NAFLD. MAFLD had higher odds for CAC than NAFLD (for CAC score > 100, odds ratio (OR) = 2.599, 95% confidence interval (CI) = 1.625-4.157; OR = 1.795, 95%CI = 1.145-2.814, respectively). In a sub-analysis, DM-MAFLD had higher odds for CAC (for CAC score > 100, OR = 5.833, 95%CI = 3.047-11.164) than the other groups of MAFLD, when compared to Neither FLD as a reference. Moreover, DM-MAFLD had a higher level of homeostasis model assessment of insulin resistance and high sensitive C-reactive protein, compared to the other groups of MAFLD. CONCLUSIONS: MAFLD was significantly associated with subclinical atherosclerosis in the general population. Additionally, DM-MAFLD could be a significant risk factor for cardiovascular disease through insulin resistance and low-grade inflammation and requires careful follow-up or appropriate intervention.

RESUMO

BACKGROUND: The endocytoscopy system (ECS) is a new method to provide real-time super-magnifying microscopic imaging in vivo. Routine diagnosis of amebic colitis requires multiple tests that are both time consuming and costly. OBJECTIVE: To determine the feasibility of ECS to directly detect the amebic parasites in vivo. DESIGN: Prospective, single-center, pilot study. SETTING: Tertiary-care university hospital. PATIENTS: This study involved 5 patients who were suspected to have amebic colitis by conventional colonoscopy in our institute. INTERVENTIONS: A super-magnifying ECS with 450 x magnification. MAIN OUTCOME MEASUREMENTS: We compared ECS findings with those of conventional methods-serum antibody tests and histology of colon biopsy specimens. RESULTS: We successfully visualized the amebic trophozoites in all 5 cases. In contrast, 3 specimens had positive results on serology, and 3 had positive histology results on hematoxylin and eosin staining. LIMITATIONS: Pilot study with a limited number of patients. Findings were compared only with serology and histology findings. CONCLUSIONS: ECS would be a useful tool for the prompt diagnosis of amebic colitis via the real-time in vivo visualization of amebic trophozoites.

RESUMO

Background and study aims Colonoscopies can predict long-term prognoses in patients with ulcerative colitis (UC). Recently, a new imaging technology has been developed that uses 3 types of illumination with center wavelengths of 540 nm, 600 nm, and 630 nm. The use of both the 600-nm and 630-nm lights (Dual red imaging; DRI) is critical for identifying blood vessels in deeper tissue. The aim of this study was to evaluate the usefulness of DRI for assessing the severity of inflammation in patients with UC. Patients and methods A total of 43 UC patients were retrospectively enrolled to evaluate the endoscopic severity of 112 colon segments, and Mayo endoscopic scores, DRI scores and the severity of inflammation on a visual analogue scale (VAS) were compared. The Mayo endoscopic scores, DRI scores, and histologic scores were evaluated, and the interobserver agreement on DRI scores among 5 investigators was also assessed. The usefulness of DRI scores for predicting prognoses was also assessed in patients with clinical remission. Results The DRI scores were closely correlated with the VAS for the severity of colonic inflammation (r = 0.96) and the histologic scores (r = 0.72 - 0.8). The DRI scores had a higher rate of interobserver agreement (κ values = 0.63 - 0.88) than the Mayo endoscopic scores (κ values = 0.44 - 0.59). Inter-observer agreement between 4 non-experts was also excellent (mean κ value = 0.76, range 0.63 - 0.82). The expected time until recurrence was significantly longer in patients with lower DRI scores (P < 0.01). Conclusion DRI can be used in patients with mild to moderate endoscopic severity because it targets the deep vascular pattern. The prognosis of UC can be predicted by assessing deep vessels using DRI.

RESUMO

BACKGROUND: There have been many reports about a variety of factors associated with incomplete colonoscopy or difficult colonoscopy with long cecal intubation time (CIT). The aim of this retrospective study was to analyze the factors related to difficult colonoscopy under conscious sedation and demonstrate the clinical utility of a small-caliber scope as rescue by using the data from a large number of subjects who underwent health check-ups. METHODS: Consecutive 1036 cases over a 12-month period (April 2015 to March 2016) were enrolled and 619 subjects were divided into two groups: Easy colonoscopy (CS) Group (CIT ≤ 10 min); Difficult CS Group (CIT > 10 min or incomplete colonoscopy by a standard scope). The two groups were compared by subjects and colonoscopy characteristics with univariate analysis followed by multivariate logistic regression analysis. Reasons for incomplete colonoscopy were also assessed. RESULTS: Cecal intubation rate increased from 97.9% to 99.9% (1007/1008) by the rescue scope. Main reasons for incomplete colonoscopy were tortuosity in the left hemicolon (38%), redundancy in the right hemicolon (29%), pain (19%) and fixation (14%). Moreover, 95% (20/21) of rescue colonoscopies were completed without additional sedation. Higher BMI (21 kg/m2 ≤ BMI) and intermediate visceral adipose tissue (VAT) (75 cm2 ≤ VAT < 150 cm2) were significantly associated with easy CS (80.7% vs 19.3%, P = 0.004; 56.3% vs 43.7%, P = 0.001) by univariate analysis. Age, gender, and VAT, not BMI, were independently associated with difficult colonoscopy by multivariate analysis (OR (95% CI), P: 0.964 (0.942, 0.985), 0.001; 1.845 (1.101, 3.091), 0.020; 2.347 (1.395, 3.951), 0.001). Subgroup analysis by gender also showed VAT as the best predictor for both genders. CONCLUSION: Difficult colonoscopy was significantly associated with advancing age, female gender and, lower (< 75 cm2) or higher (150 cm2 ≤) VAT. These subjects may benefit from having complete and more comfortable colonoscopy examinations by using the small-caliber scope rather than the standard scope.

RESUMO

BACKGROUND: The ulcerative colitis endoscopic index of severity [UCEIS] is a validated scoring system. Nevertheless, few studies have investigated its usefulness in clinical settings. In this study, we aimed to predict the clinical prognosis of patients with ulcerative colitis [UC] in clinical remission using the UCEIS. METHODS: A total of 285 UC patients who underwent a colonoscopy between April 2012 and March 2013 were enrolled. We reviewed clinical characteristics and endoscopic scores at the time of the colonoscopy and checked the clinical remission rate of the patients until September 2015. Clinical remission and recurrence were defined as a partial Mayo score of ≤1 and ≥3, respectively. RESULTS: UCEIS was strongly correlated with the Mayo endoscopic score [r=0.93], moderately correlated with clinical severity [r=0.64] and mildly correlated with C-reactive protein [r=0.34]. The recurrence rate increased gradually as it became more endoscopically severe [5.0% for UCEIS=0, 22.4% for UCEIS=1, 27.0% for UCEIS=2, 35.7% for UCEIS=3 and 75.0% for UCEIS=4-5] in patients with clinical remission. UCEIS and the concomitant use of thiopurine were independent factors predicting clinical recurrence. A multivariate analysis indicated that the absence of bleeding [p≤0.001] and the absence of mucosal damage [p<0.001] in a colonoscopy were independent factors for prolongation of clinical remission. CONCLUSION: The UCEIS is useful to predict the medium- to long-term outcomes of UC patients with clinical remission. The absence of bleeding or mucosal damage is important for maintaining clinical remission.

RESUMO

Cytoapheresis (CAP) therapy is widely used in ulcerative colitis (UC) patients with moderate to severe activity in Japan. The aim of this study is to predict the need of operation after CAP therapy of UC patients on an individual level using an artificial neural network system (ANN). Ninety UC patients with moderate to severe activity were treated with CAP. Data on the patients' demographics, medication, clinical activity index (CAI) and efficacy of CAP were collected. Clinical data were divided into training data group and validation data group and analyzed using ANN to predict individual outcomes. The sensitivity and specificity of predictive expression by ANN were 0.96 and 0.97, respectively. Events of admission, operation, and use of immunomodulator, and efficacy of CAP were significantly correlated to the outcome. Requirement of operation after CAP therapy was successfully predicted by using ANN. This newly established ANN strategy would be used as powerful support of physicians in the clinical practice.

RESUMO

BACKGROUND AND OBJECTIVE: Capsule endoscopy (CE) is a comfortable for the patients; however, CE review is time-consuming. The aim of this study was (1) to evaluate the effectiveness of the CE software in reducing the CE reading time and the number of false negatives by beginners, and (2) to determine the learning curve for reading CE images. METHODS: Capsule endoscopic images were captured by Pillcam SB (Given Imaging Ltd, Tokyo, Japan), and analyzed using the proprietary RAPID 5 software. Comparison of CE reading using different software modes: manual mode, automatic mode, and QuickView (QV) mode. Three trainee endoscopists participated as CE readers. Each participant watched CE videos in which positive findings had been predefined by trained endoscopists. Each participant read the same CE record by using one of three different software modes. These were blinded on clinical history of patients. CE reading time was recorded, and the number of false negatives was counted. Each trainee endoscopist read a total of 45 CE videos, in five steps divided into nine videos per step. RESULTS: There was no significant reader associated difference between the results for the different modes. The QV software did miss some positive findings. Therefore, the total number of instances of FN by the software plus the reader in the QV mode was significantly higher than the others. The reading times in the automatic mode and the QV mode were significantly shorter than that in the manual mode. After the second step, the number of instances of false negatives significantly decreased. CONCLUSIONS: CE software is useful for reducing the reading time. Experience of approximately 20 CE readings can be considered as the first step to becoming an expert.

RESUMO

BACKGROUND/AIMS: In capsule endoscopy (CE), the capsule does not always reach the cecum within its battery life, which may reduce its diagnostic yield. We evaluated the effect of mosapride citrate, a 5-hydroxytryptamine-4 agonist that increases gastrointestinal motility, on CE completion. METHODS: In a retrospective study, we performed univariate and multivariate analyses for 232 CE procedures performed at our hospital. To identify factors that affect CE completion, the following data were systematically collected: gender, age, gastric transit time (GTT), nonsteroidal anti-inflammatory drug administration, previous abdominal surgery, hospitalization, use of a polyethylene glycol solution, use of mosapride citrate (10 mg), body mass index (BMI), and total recording time. RESULTS: The univariate analysis showed that oral mosapride citrate, GTT, and BMI were associated with improved CE completion. Multivariate analyses showed that oral mosapride citrate (odds ratio [OR], 1.99; 95% confidence interval [CI], 1.01 to 3.91) and GTT (OR, 2.34; 95% CI, 1.13 to 4.87) were significant factors for improving the CE completion. Oral mosapride citrate significantly shortened the GTT and small bowel transit time (SBTT). CONCLUSIONS: Oral mosapride citrate reduced the GTT and SBTT during CE and improved the CE completion rate.

RESUMO

BACKGROUND: Routine diagnosis of the histopathological activity of ulcerative colitis (UC) requires multiple biopsy samples, and an endocytoscopy system (ECS) provides real-time ultra-magnifying microscopic imaging in vivo. METHODS: We have established an ECS score (ECSS) to determine a histopathological activity index of UC. Fifty-five UC patients (mean age 40.7 years; 67% men) were enrolled. A super-magnifying ECS with magnification 450× was used, and sample biopsies were obtained. Matts' histopathological grade was determined, to evaluate disease severity, by two pathologists, with consensus. The ECSS of UC was independently determined by at least two investigators, with consensus. In total, 76 pairs of ECSS and Matts' histopathological grades were independently acquired. To validate the ECSS, inter-observer agreement between three endoscopists, with consensus, and another endoscopist, was calculated as the kappa value. We also evaluated the correlation between the ECSS and Matts' histopathological grade, and between the conventional Matts' endoscopic grade and Matts' histopathological grade. RESULTS: The ECSS of UC intestinal mucosa, i.e., the sum of the indices for shape (0-3) and distance between crypts (0-2), and the visibility of superficial microvessels (0-1), showed a strong correlation with Matts' histopathological grades (ρ = 0.713, P < 0.001); as well, there was a strong correlation between the conventional Matts' endoscopic grade and Matts' histopathological grade (ρ = 0.694, P < 0.001). Furthermore, the ECSS showed high reproducibility (κ = 0.79, 95% confidence interval [CI] 0.71-0.87). CONCLUSIONS: Our novel ECSS has good predictive value for the histopathological activity of UC.
