RESUMO
High-resolution manometry (HRM) facilitates the detailed evaluation of esophageal motility. In December 2020, Chicago classification (CC) version 4.0 introduced modifications to improve consistency and accuracy. We conducted this study to compare the differences in the interpretations of HRM examinations between CC 3.0 and 4.0. Consecutive HRM records at a Taiwan tertiary medical center, including wet swallows and MRS performed in both supine and sitting positions from October 2019 to May 2021, were retrospectively reviewed and analyzed using both CC versions 3.0 and 4.0. A total of 105 patients were enrolled, and 102 patients completed the exam, while three could not tolerate HRM sitting up. Refractory gastroesophageal reflux disease (GERD) symptoms (n = 65, 63.7%) and dysphagia (n = 37, 36.3%) were the main indications. A total of 18 patients (17.6%) were reclassified to new diagnoses using CC 4.0. Of the 11 patients initially diagnosed with absent contractility, 3 (27.3%) were reclassified as having Type 1 achalasia. Of the 18 patients initially diagnosed with IEM, 6 (33.3%) were reclassified as normal. The incidence of diagnosis changes was similar in both the dysphagia and refractory GERD symptoms groups (21.6% versus 15.3%, p = 0.43). The use of CC 4.0 led to changes in the diagnoses of esophageal motility disease, irrespective of examination indications. Early adoption improves the accuracy of diagnoses and affects patient management.
RESUMO
BACKGROUND: Device-assisted enteroscopy has been used for over 20 years for the management of patients with suspected small bowel bleeding. Unlike esophagogastroduodenoscopy and colonoscopy, the appropriate timing of enteroscopy is still unknown. In recent guidelines, early enteroscopy is suggested to maximize diagnostic yield and therapeutic yield in patients with suspected small bowel bleeding. However, few studies have identified its influence on clinical outcomes, including mortality or rebleeding rate. We conducted this study to evaluate the influence of the timing of double-balloon enteroscopy on clinical outcomes in patients with suspected small bowel bleeding. METHODS: Patients with overt small bowel bleeding who underwent double-balloon enteroscopy from January 2013 to February 2021 were retrospectively reviewed. Patients were categorized into an early enteroscopy group (≤14 days) and a nonearly enteroscopy group (>14 days). Clinical outcomes, including short-term mortality and rebleeding rate, long-term mortality and rebleeding rate, diagnostic yield, and therapeutic yield, were analyzed. RESULTS: A total of 100 patients (mean age, 66.2 years; 53% male) were included, and 44 patients were stratified into the early enteroscopy group. The diagnostic yield, therapeutic yield, mortality, and rebleeding rate were similar between two groups. In multivariate conditional logistic regression analysis, there were no significant differences between two groups regarding the 30-day rebleeding rate (adjusted odds ratio [aOR], 1.43; 95% CI, 0.47-4.33), 90-day rebleeding rate (aOR, 1.18; 95% CI, 0.47-2.94), 30-day mortality rate (aOR, 1.29; 95% CI, 0.21-8.13), 90-day mortality rate (aOR, 1.94; 95% CI, 0.48-7.87), and 90-day bleeding-related mortality (aOR, 2.18; 95% CI, 0.24-19.52). The Kaplan-Meier survival curve analysis showed that the timing of DBE was not associated with the long-term rebleeding rate or mortality rate ( p = 0.57 and 0.83, respectively). CONCLUSION: The timing of enteroscopy did not influence the clinical outcomes, including the short-term mortality rate, short-term rebleeding rate, long-term mortality rate, and rebleeding rate, in patients with suspected overt small bowel bleeding.

BACKGROUND: Esophageal squamous cell neoplasms (ESCNs) are common second primary tumors in patients with head and neck cancer. Image-enhanced endoscopy (IEE) with Lugol chromoendoscopy or magnifying narrow-band imaging both increase the detection of early ESCNs. No evidence-based ESCN surveillance program for head and neck cancer patients without a history of synchronous ESCNs exists. We aimed to evaluate the performance of an IEE surveillance program with magnifying narrow-band imaging endoscopy and Lugol chromoendoscopy. METHODS: From April 2016, we routinely used IEE with magnifying narrow-band imaging and Lugol chromoendoscopy to evaluate patients with head and neck cancer history. All patients who were negative for ESCNs at the first surveillance endoscopy and received at least 2 IEEs through December 2019 were included. Demographic profiles, clinical data, cancer characteristics, IEE results and pathology reports were analyzed. RESULTS: A total of 178 patients were included. Only 4 patients (2.2%) developed metachronous ESCNs during follow-up, all of whom received curative resection treatment. The interval for the development of metachronous ESCNs was 477 to 717 days. In multivariate Firth logistic regression and KaplanâMeier survival curve analysis, Lugol's voiding lesion type C had an increased risk of esophageal cancer development (adjusted odds ratio = 15.71; 95% confidence interval, 1.33-185.87, p = 0.029). Eight patients died during the study period, and none of them had metachronous ESCNs. CONCLUSIONS: IEE with magnifying narrow-band imaging and Lugol chromoendoscopy is an effective surveillance program in head and neck cancer patients without a history of ESCNs. Annual surveillance can timely detect early ESCNs with low ESCN-related mortality.

Reprocessing of gastrointestinal (GI) endoscopes and accessories is an essential part of patient safety and quality control in GI endoscopy centers. However, current endoscopic reprocessing guidelines or procedures are not adequate to ensure patient-safe endoscopy. Approximately 5.4 % of the clinically used duodenoscopes remain contaminated with high-concern microorganisms. Thus, the Digestive Endoscopy Society of Taiwan (DEST) sets standards for the reprocessing of GI endoscopes and accessories in endoscopy centers. DEST organized a task force working group using the guideline-revision process. These guidelines contain principles and instructions of step-by-step for endoscope reprocessing. The updated guidelines were established after a thorough review of the existing global and local guidelines, systematic reviews, and health technology assessments of clinical effectiveness. This guideline aims to provide detailed recommendations for endoscope reprocessing to ensure adequate quality control in endoscopy centers.

A growing body of evidence has demonstrated an intricate association between inflammatory bowel disease (IBD) and neurodegenerative conditions, expanding beyond previous foci of comorbidities between IBD and mood disorders. These new discoveries stem from an improved understanding of the gut-microbiome-brain axis: specifically, the ability of the intestinal microbiota to modulate inflammation and regulate neuromodulatory compounds. Clinical retrospective studies incorporating large sample sizes and population-based cohorts have demonstrated and confirmed the relevance of IBD and chronic neurodegeneration in clinical medicine. In this review, we expound upon the current knowledge on the gut-microbiome-brain axis, highlighting several plausible mechanisms linking IBD with neurodegeneration. We also summarize the known associations between IBD with Parkinson disease, Alzheimer disease, vascular dementia and ischemic stroke, and multiple sclerosis in a clinical context. Finally, we discuss the implications of an improved understanding of the gut-microbiome-brain axis in preventing, diagnosing, and managing neurodegeneration among IBD and non-IBD patients.

Depression is associated with gut dysbiosis that disrupts a gut-brain bidirectional axis. Gray matter volume changes in cortical and subcortical structures, including prefrontal regions and the hippocampus, have also been noted in depressive disorders. However, the link between gut microbiota and brain structures in depressed patients remains elusive. Neuropsychiatric measures, stool samples, and structural brain images were collected from 36 patients with late-life depression (LLD) and 17 healthy controls. 16S ribosomal RNA (rRNA) gene sequencing was used to profile stool microbial communities for quantitation of microbial composition, abundance, and diversity. T1-weighted brain images were assessed with voxel-based morphometry to detect alterations in gray matter volume between groups. Correlation analysis was performed to identify the possible association between depressive symptoms, brain structures and gut microbiota. We found a significant difference in the gut microbial composition between patients with late-life depression (LLD) and healthy controls. The genera Enterobacter and Burkholderia were positively correlated with depressive symptoms and negatively correlated with brain structural signatures in regions associated with memory, somatosensory integration, and emotional processing/cognition/regulation. Our study purports the microbiota-gut-brain axis as a potential mechanism mediating the symptomatology of LLD patients, which may facilitate the development of therapeutic strategies targeting gut microbes in the treatment of elderly depressed patients.
RESUMO
BACKGROUND AND AIMS: Inflammatory bowel disease (IBD) is a chronic gastrointestinal inflammatory disorder with increasing global prevalence. The risk of IBD in patients with schizophrenia remains unclear. We aim to investigate the risk of new-onset IBD in patients with schizophrenia compared with matched controls. METHODS: We conducted a retrospective, population-based cohort study utilising patient data from the Taiwan National Health Insurance Research Database collected between January 1, 2001, and December 31, 2011. Patients diagnosed with schizophrenia by board-certified psychiatrists without prior diagnosis of IBD were enrolled and matched to controls in 1:4 fashion by age, sex, residence, income level and medical comorbidities. Adjusted hazard ratios (HRs) for new-onset IBD and sub-analyses were determined using Cox regression analysis with adjustments. RESULTS: Among 116 164 patients with schizophrenia and 464 656 matched controls, overall incidence of IBD among patients was significantly higher (1.14% vs. 0.25%). Average age of IBD diagnosis was 46.82 among patients with schizophrenia, versus 55.30 among controls. The HR of developing IBD among patients was 3.28, with a 95% confidence interval (95% CI) 2.49-4.33. IBD risk was higher among patients with psychiatric admissions more than once per year (HR 7.99, 95% CI 5.25-12.15) compared to those hospitalised less frequently (HR 2.72, 95% CI 2.03-3.66). CONCLUSIONS: This population-based cohort study demonstrates a significant association between schizophrenia and subsequent IBD development. Patients with schizophrenia develop IBD at a younger age, and the risk increases with inadequately controlled schizophrenia. Physician vigilance and awareness of this correlation will improve IBD diagnosis and management among this vulnerable patient population.

Background: Adequate bowel cleansing is important for colonoscopy performance evaluation. Current bowel cleansing evaluation scales are subjective, with a wide variation in consistency among physicians and low reported rates of accuracy. We aim to use machine learning to develop a fully automatic segmentation method for the objective evaluation of the adequacy of colon preparation. Methods: Colonoscopy videos were retrieved from a video data cohort and transferred to qualified images, which were randomly divided into training, validation, and verification datasets. The fecal residue was manually segmented. A deep learning model based on the U-Net convolutional network architecture was developed to perform automatic segmentation. The performance of the automatic segmentation was evaluated on the overlap area with the manual segmentation. Results: A total of 10,118 qualified images from 119 videos were obtained. The model averaged 0.3634 s to segmentate one image automatically. The models produced a strong high-overlap area with manual segmentation, with 94.7% ± 0.67% of that area predicted by our AI model, which correlated well with the area measured manually (r = 0.915, p < 0.001). The AI system can be applied in real-time qualitatively and quantitatively. Conclusions: We established a fully automatic segmentation method to rapidly and accurately mark the fecal residue-coated mucosa for the objective evaluation of colon preparation.
RESUMO
BACKGROUND: In the coronavirus disease 2019 (COVID-19) pandemic, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) vaccination has been effective in preventing COVID-19 infections and related mortality. The SARS-CoV-2 vaccination was also recommended by the international society for patients with inflammatory bowel disease (IBD). However, IBD patients were not recruited in prospective randomized clinical vaccine studies. To evaluate the efficacy and safety of SARS-CoV-2 vaccination in IBD patients, we conducted this systemic review and meta-analysis. METHODS: We systematically searched PubMed, Medline, and the Cochrane Library for studies published between January 1, 2019, and September 9, 2021. Studies written in English reported the efficacy, seroconversion (anti-SARS-CoV-2 anti-spike (S) antibody titer beyond the threshold) rate, and adverse events after the SARS-CoV-2 vaccination in IBD patients. We extracted the author, date, study design, country, types of SARS-CoV-2 vaccination, number of IBD patients receiving SARS-CoV-2 vaccinations, and study outcomes. Published data from the enrolled studies were pooled to determine effect estimates. The study protocol was registered in PROSPERO (CRD42021264993). RESULTS: We analyzed findings from 27 454 IBD patients who received SARS-CoV-2 vaccinations in 11 studies that met the inclusion criteria. The post-SARS-CoV-2 vaccination COVID-19 infection rate was comparable between the IBD patients and non-IBD patients (odds ratio [OR], 1.28 [95% CI, 0.96-1.71]) and higher in nonvaccinated IBD patients compared with vaccinated IBD patients (OR, 8.63 [95% CI, 5.44-13.37]). The adverse event rate, severe adverse events, and mortality after the SARS-CoV-2 vaccination were 69%, 3%, and 0%, respectively. CONCLUSION: The SARS-CoV-2 vaccine is effective and tolerated in preventing COVID-19 infections in IBD patients. Over 98% of patients had seroconversion after receiving all doses of the SARS-CoV-2 vaccination, and the influence of biologics on vaccination was limited. The SARS-CoV-2 vaccination is recommended for IBD patients.

BACKGROUND: With the growth of the aging population, the need for colonoscopies in nonagenarians is rising. However, few data on colonoscopies in extremely elderly individuals are available. To better acknowledge the role of colonoscopies in this specific group of patients, we conducted this study to evaluate the safety and clinical impact of colonoscopy in nonagenarian patients. METHODS: We performed a retrospective cohort study comparing nonagenarians who received colonoscopy in a tertiary medical center in Taiwan in 2016 with 76- to 80-year-old patients (relatively elderly patients) who were 1:1 propensity score matched by sex as the control subjects. The postcolonoscopy 30-day adverse events, mortality, and long-term survival were recorded. RESULTS: A total of 137 nonagenarians and 137 relatively elderly patients were included. The nonagenarians receiving colonoscopy were more likely to be hospitalized (40.1% vs 19.7%, p < 0.001), and the adjusted colonoscopy completion rates were comparable in both groups (92.0% vs 97.1%, p = 0.063). The overall adverse event rate and postcolonoscopy 30-day mortality rates were low in both groups (2.9% vs 1.5%, p = 0.409 and 2.2% vs 1.5%, p = 0.652, respectively). A total of 18.2% of the nonagenarians were diagnosed with advanced neoplasia. Among the nonagenarians diagnosed with colorectal cancer, the patients receiving surgery had a significantly lower risk of death than the patients receiving conservative management (hazards ratio 0.1044, 0.01275-0.8529, p = 0.0352). CONCLUSION: Colonoscopy in patients older than 90 years is generally safe. Colonoscopy findings that led to surgery in nonagenarians diagnosed with colorectal cancer were associated with survival benefits.

OBJECTIVES: Computer-aided diagnosis (CAD)-based artificial intelligence (AI) has been shown to be highly accurate for detecting and characterizing colon polyps. However, the application of AI to identify normal colon landmarks and differentiate multiple colon diseases has not yet been established. We aimed to develop a convolutional neural network (CNN)-based algorithm (GUTAID) to recognize different colon lesions and anatomical landmarks. METHODS: Colonoscopic images were obtained to train and validate the AI classifiers. An independent dataset was collected for verification. The architecture of GUTAID contains two major sub-models: the Normal, Polyp, Diverticulum, Cecum and CAncer (NPDCCA) and Narrow-Band Imaging for Adenomatous/Hyperplastic polyps (NBI-AH) models. The development of GUTAID was based on the 16-layer Visual Geometry Group (VGG16) architecture and implemented on Google Cloud Platform. RESULTS: In total, 7838 colonoscopy images were used for developing and validating the AI model. An additional 1273 images were independently applied to verify the GUTAID. The accuracy for GUTAID in detecting various colon lesions/landmarks is 93.3% for polyps, 93.9% for diverticula, 91.7% for cecum, 97.5% for cancer, and 83.5% for adenomatous/hyperplastic polyps. CONCLUSIONS: A CNN-based algorithm (GUTAID) to identify colonic abnormalities and landmarks was successfully established with high accuracy. This GUTAID system can further characterize polyps for optical diagnosis. We demonstrated that AI classification methodology is feasible to identify multiple and different colon diseases.

BACKGROUND: Depressive disorder is a major psychiatric illness, and a disturbed brain-gut-microbiome axis may contribute to its pathophysiology. Chronic Helicobacter pylori (H. pylori) infections are common in the general population and using multiple antibiotics is required for its eradication, which is associated with gut dysbiosis and may lead to depression. We aimed to evaluate the risk of psychiatrist-diagnosed depression in patients with peptic ulcer diseases (PUD) receiving anti-H. pylori therapy. MATERIALS AND METHODS: We collected data from the National Health Insurance Research Database (NHIRD) in Taiwan on PUD patients undergoing antibiotic treatment for H. pylori infection; patients and controls were matched for age, sex, income, level of urbanization, and comorbidities. RESULTS: Of the 1 million beneficiaries in the NHIRD, we identified 7087 patients for inclusion in the eradication cohort and 7087 matched non-eradication controls with PUD. Antibiotic therapy is associated with a short-term (<30 days) increase in the incidence of psychiatrist-diagnosed depressive disorder (p = 0.009, after multiple comparisons with Bonferroni correction) in the eradication cohort compared with the controls. Female (OR: 4.55, 95% CI: 1.53-13.48) PUD patients were more likely to display an increased risk of depression within 30 days after eradication therapy. Clarithromycin use was related to an elevated likelihood (OR: 3.14, 95% CI: 1.45-6.80) of subsequent depressive disorder within 30 days after eradication therapy. CONCLUSIONS: Antibiotic eradication treatment for H. pylori infection is associated with a significant short-term (less than 30 days) increase in the incidence of psychiatrist-diagnosed depressive disorder, which can be overlooked by gastroenterologists and general practitioners.

BACKGROUND/AIMS: Gastroparesis is identified as a subject that is understudied in Asia. The scientific committee of the Asian Neurogastroenterology and Motility Association performed a Knowledge, Attitude, and Practices survey on gastroparesis among doctors in Asia. METHODS: The questionnaire was created and developed through a literature review of current gastroparesis works of literature by the scientific committee of Asian Neurogastroenterology and Motility Association. RESULTS: A total of 490 doctors from across Asia (including Bangladesh, China, Hong Kong, Indonesia, Japan, Malaysia, Myanmar, the Philippines, Singapore, South Korea, Taiwan, Thailand, and Vietnam) participated in the survey. Gastroparesis is a significant gastrointestinal condition. However, a substantial proportion of respondents was unable to give the correct definition and accurate diagnostic test. The main reason for lack of interest in diagnosing gastroparesis was "the lack of reliable diagnostic tests" (46.8%) or "a lack of effective treatment" (41.5%). Only 41.7% of respondents had access to gastric emptying scintigraphy. Most doctors had never diagnosed gastroparesis at all (25.2%) or diagnosed fewer than 5 patients a year (52.1%). CONCLUSIONS: Gastroparesis can be challenging to diagnose due to the lack of instrument, standardized method, and paucity of research data on normative value, risk factors, and treatment studies in Asian patients. Future strategies should concentrate on how to disseminate the latest knowledge of gastroparesis in Asia. In particular, there is an urgent need to estimate the magnitude of the problems in high risk and idiopathic patients as well as a standardized diagnostic procedure in Asia.
RESUMO
BACKGROUND: Older adults with depression more frequently experience somatic and gastrointestinal (GI) problems compared with people without depression and younger adults with depression. However, whether GI symptoms are predictive of elevated rates of depression among older adults is unclear. METHODS: We enrolled 106 older adults (>60 years old); 69 had late-life depression (LLD), and 37 were controls. All participants gave ratings on the Gastrointestinal Symptom Rating Scale (GSRS) and Hamilton Depression Rating Scale. Food consumption was assessed using a food frequency questionnaire, and a Mediterranean diet score was used as a covariate. RESULTS: Compared with the controls, patients with LLD reported higher levels of depressive and GI symptoms and reported more reflux, abdominal pain, and dyspepsia symptoms, and these symptoms were correlated with Hamilton Depression Rating Scale scores (GSRS total: ß = 0.47; reflux: ß = 1.47; abdominal pain: ß = 1.98; dyspepsia: ß = 1.02; all p < 0.01). After demographic variables and Mediterranean diet score were controlled for, a logistic regression analysis indicated that total GSRS score was an independent determinant of LLD (odds ratio: 1.20, 95% CI: 1.04-1.38). Moreover, a stratified analysis by depression severity indicated that higher total GSRS score may contribute to greater depression severity (odds ratio: 1.25, 95% CI: 1.04-1.52). CONCLUSION: We provide evidence that GI symptoms are associated with depressive symptoms among patients with LLD. Older people with more specific GI symptoms, such as reflux, abdominal pain, and dyspepsia, are potentially at greater risk of having LLD.

BACKGROUND: The new coronavirus disease (COVID-19) has high infection and mortality rates, and has become a pandemic. The infection and mortality rates are lower in Asian countries than in European countries. This study aimed to conduct a survey on the effects of COVID-19 on the capacity to perform gastrointestinal motility tests in Asian countries compared with European countries. METHODS: We used the questionnaire previously established by our team for researchers in European countries. The correlation between the decreased rate of gastrointestinal motility and function tests, and the infection/mortality rates of COVID-19 and stringency of a government's interventions in each country was analysed and protective measures were assessed. RESULTS: In total, 58 gastroenterologists/motility experts in Asian countries responded to this survey. The infection/mortality rates of COVID-19 and Stringency Index had a significant impact on the testing capacity of oesophageal manometry and catheter-based pH monitoring. In European countries, most facilities used filtering facepiece 2/3 (FFP2/3) masks during oesophageal motility studies. Meanwhile, in Asian countries, most facilities used surgical masks. CONCLUSION: The total infection and mortality rates of COVID-19 can affect the rate of gastrointestinal motility testing and the type of protective equipment that must be used.
RESUMO
Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder characterized by abdominal pain and alterations in bowel habits. Current treatments for IBS are unsatisfactory due to its multifactorial pathogenesis involving the microbiota-gut-brain axis. Lactobacillus plantarum PS128 (PS128) was reported to exhibit neuromodulatory activity which may be beneficial for improving IBS. This study aimed to investigate the effect of PS128 on visceral hypersensitivity (VH) and the gut-brain axis using a 5-hydroxytryptophan (5-HTP)-induced VH rat model without colonic inflammation induction, mimicking the characteristics of IBS. Male Sprague-Dawley rats were administered with PS128 (109 CFU in 0.2 mL saline/rat/day) or saline (0.2 mL saline/rat/day) for 14 days. Colorectal distension (CRD) with simultaneous electromyography recording was performed 30 min before and 30 min after the 5-HTP injection. Levels of neuropeptides and neurotrophins were analyzed. PS128 significantly reduced VH induced by the 5-HTP injection and CRD. Neurotransmitter protein levels, substance P, CGRP, BDNF, and NGF, were decreased in the dorsal root ganglion but increased in the spinal cord in response to the 5-HTP injection; PS128 reversed these changes. The hypothalamic-pituitary-adrenal axis was modulated by PS128 with decreased corticosterone concentration in serum and the expression of mineralocorticoid receptors in the amygdala. Oral administration of PS128 inhibited 5-HTP-induced VH during CRD. The ameliorative effect on VH suggests the potential application of PS128 for IBS.
