Abstract
INTRODUCTION The 2021 American College of Gastroenterology Guidelines suggested using of intravenous erythromycin before endoscopy in patients with upper gastrointestinal bleeding (UGIB) to enhance endoscopic view and reduce the need for repeat endoscopy. Evidence on intravenous metoclopramide, which is more accessible, is scant, especially in patients with active UGIB. This study aimed to evaluate the efficacy of metoclopramide for gastric visualization in patients with active UGIB. METHODS Between April 10, 2021, and October 8, 2022, this double-blind, double-center randomized controlled trial enrolled patients with active UGIB (hematemesis or presence of fresh blood in the nasogastric tube). The eligible patients were randomly assigned in a concealed 1:1 allocation to metoclopramide or placebo. The primary outcome was adequate visualization by objective endoscopic visualized gastroduodenal scores (EVS). Secondary outcomes included mean difference in EVS, duration of esophagogastroduodenoscopy (EGD), immediate hemostasis, need for a second look EGD, units of blood transfusion, length of hospital stay, and 30-day rebleeding rate. RESULTS Of the 68 eligible patients, 3 of each group were excluded by protocol violation. Finally, 62 patients (31 metoclopramide and 31 placebo) were analyzed. The percentage of patients with adequate visualization in metoclopramide and placebo group was 77.4% and 61.6% (odds ratio [OR] 2.16 [0.71-6.58], P = 0.16). The need for a second look EGD in the 72 hours was lower in the metoclopramide group (3.2% vs 22.6%, OR 0.11 [0.01-0.99], P = 0.02), whereas the other secondary outcomes were not different. However, in gastric lesions subgroup analysis, metoclopramide improved the adequate visualization rate (92.9% vs 50%, OR 13 [1.32-128.10], P = 0.03) and mean EVS at fundus (1.79 ± 0.42 vs 1.29 ± 0.72; P = 0.03). DISCUSSION Metoclopramide did not improve endoscopic visualization but decreased the need for second look EGD in patients with overall active UGIB. It improved gastric visualization in those with UGIB due to gastric lesions, primarily by improving visualization in the fundus ( ClinicalTrials.gov number NCT04771481).

Abstract
OBJECTIVES This consensus was developed by the Asian EUS Group (AEG), who aimed to formulate a set of practice guidelines addressing various aspects of endoscopic ultrasound-guided tissue acquisition (EUS-TA). METHODS The AEG initiated the development of consensus statements and formed an expert panel comprising surgeons, gastroenterologists, and pathologists. Three online consensus meetings were conducted to consolidate the statements and votes. The statements were presented and discussed in the first two consensus meetings and revised according to comments. Final voting was conducted at a third consensus meeting. The Grading of Recommendations, Assessment, Development, and Evaluation system was adopted to define the strength of the recommendations and quality of evidence. RESULTS A total of 20 clinical questions and statements regarding EUS-TA were formulated. The committee recommended that fine-needle biopsy (FNB) needles be preferred over conventional fine-needle aspiration (FNA) needles for EUS-TA of subepithelial lesions. For solid pancreatic masses, rapid on-site evaluation is not routinely recommended when FNB needles are used. For dedicated FNB needles, fork-tip and Franseen-tip needles have essentially equivalent performance. CONCLUSION This consensus provides guidance for EUS-TA, thereby enhancing the quality of EUS-TA.

Abstract
BACKGROUND Endoscopists' experience influences narrow-band imaging (NBI)-guided gastric intestinal metaplasia (GIM) diagnostic performance. We aimed to evaluate the general gastroenterologists (GE) performance in NBI-guided GIM diagnosis compared to NBI experts (XP) and assess GEs' learning curve. METHODS A cross-sectional study was conducted between 10/2019 and 2/2022. Histology-proven GIM who underwent esophagogastroduodenoscopy (EGD) were randomly assessed by 2XPs or 3GEs. Endoscopists' performance on NBI-guided diagnoses were compared to the pathological diagnosis (gold standard) in five areas of the stomach according to the Sydney protocol. The primary outcome were GIM diagnosis validity scores of GEs compared to XPs. The secondary outcome was the minimum number of lesions required for GEs to achieve an accuracy of GIM diagnosis ≥ 80%. RESULTS One thousand one hundred and fifty-five lesions from 189 patients (51.3% male, mean age 66 ± 10 years) were examined. GEs performed EGD in 128 patients with 690 lesions. the GIM diagnosis sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of GEs compared to the XPs, were 91% vs.93%, 73% vs.83%, 79% vs.83%, 89% vs.93%, and 83% vs.88%, respectively. GEs demonstrated lower specificity (mean difference - 9.4%; 95%CI - 16.3, 1.4; p = 0.008) and accuracy (mean difference - 5.1%; 95%CI - 3.3, 6.3; p = 0.006) compared to XPs. After 100 lesions (50% GIM), GEs achieved an accuracy of ≥ 80% and all diagnostic validity scores were comparable to the XPs (p < 0.05 all). CONCLUSIONS Compared to XPs, GEs had lower specificity and accuracy for GIM diagnosis. The learning curve for a GE to achieve comparable performance to XPs would necessitate at least 50 GIM lesions.

Abstract
BACKGROUND & AIMS Current guidelines vary as to their recommendations addressing the role of hemostatic powders when managing patients with malignant gastrointestinal (GI) bleeding because these are based on very-low- to low-quality evidence, in large part due to a paucity of randomized trial data. METHODS This was a patient- and outcome assessor-blinded, multicenter, randomized controlled trial. Patients presenting with active bleeding from an upper or lower GI lesion suspected to be malignant at index endoscopy between June 2019 and January 2022 were randomly allocated to receive either TC-325 alone or standard endoscopic treatment (SET). The primary outcome was 30-day rebleeding, and secondary objectives included immediate hemostasis and other clinically relevant endpoints. RESULTS Overall, 106 patients made up the study population (55 TC-325 and 51 SET, after 1 exclusion in the TC-325 group and 5 in the SET group). Baseline characteristics and endoscopic findings did not differ between the groups. Thirty-day rebleeding was significantly lower in the TC-325 (2.1% TC-325 vs 21.3% SET; odds ratio, 0.09; 95% confidence interval [CI], 0.01-0.80; P = .003). Immediate hemostasis rates were 100% in the TC-325 group vs 68.6% in the SET group (odds ratio, 1.45; 95% CI, 0.93-2.29; P < .001). Other secondary outcomes did not differ between the 2 groups. Independent predictors of 6-month survival included the Charlson comorbidity index (hazard ratio, 1.17; 95% CI, 1.05-1.32; P = .007) and receiving an additional nonendoscopic hemostatic or oncologic treatment during 30 days after the index endoscopy (hazard ratio, 0.16; 95% CI, 0.06-0.43; P < .001) after adjustment for functional status, Glasgow-Blatchford score, and an upper GI source of bleeding. CONCLUSION The TC-325 hemostatic powder results in greater immediate hemostasis rates followed by lower 30-day rebleeding rates when compared to contemporary SET.

Abstract
INTRODUCTION Over-the-scope clip (OTSC) has been used recently for primary haemostasis of peptic ulcers. This study aimed to compare the efficacy of OTSC to standard endoscopic therapy in primary treatment of patients with peptic ulcer bleeding that are of size ≥1.5 cm. The target population accounts for only 2.5% of all upper GI bleeders. METHODS This was a multicentre international randomised controlled trial from July 2017 to October 2020. All patients with Forest IIa or above peptic ulcers of ≥1.5 cm were included. Primary outcome was 30-day clinical rebleeding. Secondary endpoints include 3-day all-cause mortality, transfusion requirement, hospital stay, technical and clinical success, and further interventions. 100 patients are needed to yield a power of 80% to detect a difference of -0.15 at the 0.05 significance level (alpha) using a two-sided Z-test (pooled). RESULTS 100 patients were recruited. Success in achieving primary haemostasis was achieved in 46/50 (92%) and 48/50 (96%) in the OTSC and conventional arm, respectively. Among patients who had success in primary haemostasis, 2/46 (4.35%) patients in the OTSC arm and 9/48 (18.75%) patients in the conventional arm developed 30-day rebleeding (p=0.03). However, in an intention-to-treat analysis, there was no difference in rebleeding within 30 days (5/50 (10%) OTSC vs 9/50 (18%) standard, p=0.23) or all-cause mortality (2/50 (4%) OTSC vs 4/50 (8%) standard, p=0.68; OR=2.09, 95% CI 0.37 to 11.95). There was also no difference in transfusion requirement, hospital stay, intensive care unit admission and further interventions. CONCLUSION The routine use of OTSC as primary haemostasis in large bleeding peptic ulcers was not associated with a significant decrease in 30-day rebleeding. TRIAL REGISTRATION NUMBER NCT03160911.

Abstract
This work presents real-time segmentation viz. gastric intestinal metaplasia (GIM). Recently, GIM segmentation of endoscopic images has been carried out to differentiate GIM from a healthy stomach. However, real-time detection is difficult to achieve. Conditions are challenging, and include multiple color modes (white light endoscopy and narrow-band imaging), other abnormal lesions (erosion and ulcer), noisy labels etc. Herein, our model is based on BiSeNet and can overcome the many issues regarding GIM. Application of auxiliary head and additional loss are seen to improve performance as well as enhance multiple color modes accurately. Further, multiple pre-processing techniques are utilized for leveraging detection performance: namely, location-wise negative sampling, jigsaw augmentation, and label smoothing. Finally, the decision threshold can be adjusted separately for each color mode. Work undertaken at King Chulalongkorn Memorial Hospital examined 940 histologically proven GIM images and 1239 non-GIM images, obtained over 173 frames per second (FPS). In terms of accuracy, our model is seen to outperform all baselines. Our results demonstrate sensitivity, specificity, positive predictive, negative predictive, accuracy, and mean intersection over union (IoU), achieving GIM segmentation values of 91%, 96%, 91%, 91%, 96%, and 55%, respectively.

Abstract
BACKGROUND AND AIMS Esophagogastroduodenoscopy (EGD) has been identified as an aerosol-generating procedure (AGP) during the COVID-19 pandemic. The risk of AGP and benefits of utilizing protective measures have never been fully studied. METHODS A randomized control, open-label study in patients scheduled for diagnostic EGD between September and December 2021 was conducted. Patients were randomly assigned to either head box group or without head box group (control group). Particles were measured with six-size particle counters at the nurse anesthetist and endoscopist position. Primary composite outcomes were the mean difference of aerosol particle levels during and before EGD at the nurse anesthetist face position and at the endoscopist face position. Secondary outcomes were factors increasing aerosol particle levels and safety of the head box. RESULTS From 196 enrolled patients, 190 were analyzed. Baseline characteristics were not different between the two groups. The mean distance between endoscopist face and patient mouth was 67.2 ± 4.9 cm. The mean differences of 0.3-, 0.5-, and 1.0-μm particles during the procedure and at baseline before the procedure at nurse anesthetist position and the mean differences of 0.3-μm particles at the endoscopist position was found to have decreased in the head box group and increased in the control group (P < 0.001, 0.001, 0.014, and P < 0.001, respectively). Cough, burping, and body movement increased aerosol particles. No additional adverse events were observed in the head box group. CONCLUSIONS EGD with the head box is safe and can reduce significant aerosolization to endoscopy personnel including nurse anesthetists and endoscopists.

Abstract
Abstract
Background
Gastrointestinal (GI) bleeding is one of the most impactful complications in patients hospitalized from COVID-19 infection. Limited study has focused on patients with upper GI bleeding (UGIB). This study aimed to identify the risk factors of patients who were hospitalized from COVID-19 infection and developed UGIB as well as the effectiveness of proton pump inhibitor (PPI) prophylaxis in those patients.
Methods
This study was comprised of two phases. The first phase was the retrospective enrollment of patients who were admitted due to COVID-19 infection and developed UGIB between April and August 2021 to evaluate the associated factors of active UGIB. The second phase was a retrospective analysis after PPI prophylaxis protocol from September – October 2021 to assess the benefit of PPI use in those patients.
Results
Of 6,373 patients hospitalized, 43 patients (0.7%) had evidence of UGIB. The majority were male 28 (65.1%) with a mean age of 69.1 ± 11.8 years. Twenty-four of 43 patients (55.8%) needed mechanical ventilation, 35 patients (81.4%) received systemic corticosteroids, and 10 patients (23.3%) were taking anticoagulants for venous thromboembolic prophylaxis. Seven of 43 patients (16%) had active UGIB. There was no significant difference in the number of patients taking antiplatelets, anticoagulants, or steroids and the severity of COVID-19 infection between the two groups. An emergency endoscopy or endoscopic hemostasis were performed in 6/7 (85.7%) patients. The multivariate logistic regression analysis revealed two significant factors associated with active UGIB including higher of Glasgow-Blatchford score (GBS) per point (OR = 7.89; 95%CI 1.03–72.87; p = 0.04) and an absence of PPI use (OR 4.29; 95%CI 1.04–19.51; p = 0.04). After prescribing PPI as a prophylaxis, there was a slightly lower incidence of UGIB (0.6% vs 0.7%) in addition to an absence of active UGIB (0% vs 16%).
Conclusion
Our study demonstrated that the absence of PPI and higher GBS were significant risk factors for active UGIB which required therapeutic endoscopy in patients with COVID-19 infection. We suggest that short-term PPI prophylaxis should be prescribed in those patients once they need hospitalization regardless of the severity of COVID-19 infection to minimize the severity of UGIB.

Abstract
INTRODUCTION Fecal microbiota transplantation (FMT) has been proposed as a potential treatment for irritable bowel syndrome (IBS); however, the consensus regarding its efficacy and safety is limited. MATERIALS AND METHODS We performed a systematic search of the literature using PubMed, EMBASE, Ovid MEDLINE, and Cochrane. Meta-analyses were conducted in relative risk (RR) or standard mean difference (SMD) using 95% confidence intervals (CI). Cochrane risk-of-bias 2 tool (RoB2) was employed to evaluate the study quality. RESULT Of 2,589 potential records, 7 studies with 9 cohorts involving 505 participants were included. Meta-analyses showed no significant difference in the short-term (12 weeks) and long-term (12 months) global improvement of IBS symptoms of FMT vs. placebo (RR 0.63, 95% CI 0.39-1.00 and RR 0.88, 95% CI 0.53-1.45, respectively). There were statistically significant differences of short-term IBS-SSS improvement (SMD -0.58, 95% CI -1.09 to -0.88) and short-term IBS-QoL improvement (SMD 0.67, 95% CI 0.43-0.91). Eight from 9 studies (88.9%) had a low risk of bias. The subgroup analysis revealed the short-term global symptoms improvement in studies with low-risk of bias (RR 0.53, 95% CI 0.35-0.81), studies with well-defined donors (RR 0.31, 95% CI 0.14-0.72), and studies with FMT using colonoscopy (RR 0.66, 95% CI 0.47-0.92). Major FMT adverse events are transient and rapidly self-limiting. CONCLUSION FMT significantly improved IBS-SSS and IBS-QoL in the short-term period in IBS patients. However, global symptom improvement showed no significance. Well-defined donors and appropriate fecal administration routes appear to be important factors for the successful outcomes of FMT in IBS.

Abstract
BACKGROUND The recommendation of second look endoscopy (SLOGD) in selected patients at high risk for rebleeding has been inconclusive. This study aimed to evaluate the benefit of SLOGD in selected patients predicted at high risk of recurrent bleeding. METHODS From a cohort of 939 patients with bleeding peptic ulcers who underwent endoscopic hemostasis, we derived a 9-point risk score (age > 60, Male, ulcer ≥ 2 cm in size, posterior bulbar or lesser curve gastric ulcer, Forrest I bleeding, haemoglobin < 8 g/dl) to predict recurrent bleeding. We then validated the score in another cohort of 1334 patients (AUROC 0.77). To test the hypothesis that SLOGD in high-risk patients would improve outcomes, we did a randomized controlled trial to compare scheduled SLOGD with observation alone in those predicted at high risk of rebleeding (a score of ≥ 5). The primary outcome was clinical bleeding within 30 days of the index bleed. RESULTS Of 314 required, we enrolled 157 (50%) patients (SLOGD n = 78, observation n = 79). Nine (11.8%) in SLOGD group and 14 (18.2%) in observation group reached primary outcome (absolute difference 6.4%, 95% CI - 5.0% to 17.8%). Twenty-one of 69 (30.4%) patients who underwent SLOGD needed further endoscopic treatment. No surgery for bleeding control was needed. There were 6 vs. 3 of 30-day deaths in either group (p = 0.285, log rank). No difference was observed regarding blood transfusion and hospitalization. CONCLUSIONS In this aborted trial that enrolled patients with bleeding peptic ulcers at high-risk of recurrent bleeding, scheduled SLOGD did not significantly improve outcomes.

Abstract
Background/Aims Previous artificial intelligence (AI) models attempting to segment gastric intestinal metaplasia (GIM) areas have failed to be deployed in real-time endoscopy due to their slow inference speeds. Here, we propose a new GIM segmentation AI model with inference speeds faster than 25 frames per second that maintains a high level of accuracy.
Methods Investigators from Chulalongkorn University obtained 802 histological-proven GIM images for AI model training. Four strategies were proposed to improve the model accuracy. First, transfer learning was employed to the public colon datasets. Second, an image preprocessing technique contrast-limited adaptive histogram equalization was employed to produce clearer GIM areas. Third, data augmentation was applied for a more robust model. Lastly, the bilateral segmentation network model was applied to segment GIM areas in real time. The results were analyzed using different validity values.
Results From the internal test, our AI model achieved an inference speed of 31.53 frames per second. GIM detection showed sensitivity, specificity, positive predictive, negative predictive, accuracy, and mean intersection over union in GIM segmentation values of 93%, 80%, 82%, 92%, 87%, and 57%, respectively.
Conclusions The bilateral segmentation network combined with transfer learning, contrast-limited adaptive histogram equalization, and data augmentation can provide high sensitivity and good accuracy for GIM detection and segmentation.

Abstract
Background and study aims According to a recent guideline, patients with gastric intestinal metaplasia (GIM) should have at least five biopsies performed under the Sydney protocol to evaluate for risk of extensive GIM. However, only narrow-band imaging (NBI)-targeted biopsy may be adequate to diagnose extensive GIM. Patients and methods A cross-sectional study was conducted between November 2019 and October 2020. Patients with histology-proven GIM were enrolled. All patients underwent standard esophagogastroduodenoscopy performed by a gastroenterology trainee. The performing endoscopists took biopsies from either a suspected GIM area (NBI-targeted biopsy) or randomly (if negative for GIM read by NBI) to complete five areas of the stomach as per the Sydney protocol. The gold standard for GIM diagnosis was pathology read by two gastrointestinal pathologists with unanimous agreement. Results A total of 95 patients with GIM were enrolled and 50 (52.6%) were men with a mean age of 64 years. Extensive GIM was diagnosed in 43 patients (45.3%). The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of NBI-targeted biopsy vs. the Sydney protocol were 88.4% vs.100 %, 90.3% vs. 90.3%, 88.4% vs. 89.6%, 90.3% vs. 100%, and 89.5% vs. 94.7%, respectively. The number of specimens from NBI-targeted biopsy was significantly lower than that from Sydney protocol (311vs.475, P < 0.001). Conclusions Both NBI-targeted biopsy and Sydney protocol by a gastroenterologist who was not an expert in NBI and who has experience with diagnosis of at least 60 cases of GIM provided an NPV higher than 90%. Thus, targeted biopsy alone with NBI, which requires fewer specimens, is an alternative option for extensive GIM diagnosis.

Abstract
Gastroesophageal reflux disease (GERD) is one of the most prevalent and bothersome functional gastrointestinal disorders worldwide, including in Thailand. After a decade of the first Thailand GERD guideline, physician and gastroenterologist encountered substantially increase of patients with GERD. Many of them are complicated case and refractory to standard treatment. Concurrently, the evolution of clinical characteristics as well as the progression of investigations and treatment have developed and changed tremendously. As a member of Association of Southeast Asian Nations, which are developing countries, we considered that the counterbalance between advancement and sufficient economy is essential in taking care of patients with GERD. We gather physicians from university hospitals, as well as internist and general practitioners who served in rural area, to make a consensus in this updated version of GERD guideline focusing in medical management of GERD. This clinical practice guideline was constructed adhering with standard procedure. We categorized the guideline in to four parts including definition, investigation, treatment, and long-term follow up. We anticipate that this guideline would improve physicians' proficiency and help direct readers to choose investigations and treatments in patients with GERD wisely. Moreover, we wish that this guideline would be applicable in countries with limited resources as well.

Abstract
BACKGROUND The effectiveness of the hemostatic powder TC-325 as a single endoscopic treatment for acute nonvariceal upper gastrointestinal bleeding is uncertain. OBJECTIVE To compare TC-325 with standard endoscopic hemostatic treatments in the control of active bleeding from nonvariceal upper gastrointestinal causes. DESIGN One-sided, noninferiority, randomized, controlled trial. (ClinicalTrials.gov: NCT02534571). SETTING University teaching hospitals in the Asia-Pacific region. PATIENTS 224 adult patients with acute bleeding from a nonvariceal cause on upper gastrointestinal endoscopy. INTERVENTION TC-325 (n = 111) or standard hemostatic treatment (n = 113). MEASUREMENTS The primary outcome was control of bleeding within 30 days. Other outcomes included failure to control bleeding during index endoscopy, recurrent bleeding after initial hemostasis, further interventions, blood transfusion, hospitalization, and death. RESULTS 224 patients were enrolled (136 with gastroduodenal ulcers [60.7%], 33 with tumors [14.7%], and 55 with other causes of bleeding [24.6%]). Bleeding was controlled within 30 days in 100 of 111 patients (90.1%) in the TC-325 group and 92 of 113 (81.4%) in the standard treatment group (risk difference, 8.7 percentage points [1-sided 95% CI, 0.95 percentage point]). There were fewer failures of hemostasis during index endoscopy with TC-325 (3 [2.7%] vs. 11 [9.7%]; odds ratio, 0.26 [CI, 0.07 to 0.95]). Recurrent bleeding within 30 days did not differ between groups (9 [8.1%] vs. 10 [8.8%]). The need for further interventions also did not differ between groups (further endoscopic treatment: 8 [7.2%] vs. 10 [8.8%]; angiography: 2 [1.8%] vs. 4 [3.5%]; surgery: 1 [0.9%] vs. 0). There were 14 deaths in each group (12.6% vs. 12.4%). LIMITATION Clinicians were not blinded to treatment. CONCLUSION TC-325 is not inferior to standard treatment in the endoscopic control of bleeding from nonvariceal upper gastrointestinal causes.

Abstract
BACKGROUND AND OBJECTIVES Due to rebalanced haemostasis in cirrhosis, viscoelastometric testing (VET) is more accurate than standard coagulation tests (SCTs) in preprocedural haemostatic evaluation, resulting in decreased unnecessary transfusion. We aimed to determine the impact of VET-guided strategy on postprocedural bleeding, periprocedural transfusion rates and quantities, transfusion-related adverse events (TRAEs), lengths of stay (LOS) and mortality from randomized controlled trials (RCTs) of cirrhotic patients. METHODS PubMed and EMBASE were searched for RCTs comparing VET-guided with SCT-guided transfusion in cirrhotic adults undergoing esophagogastroduodenoscopy, liver transplantation or other invasive interventions. Using random-effects models, the pooled risk ratios (RRs) and/or mean differences (MDs) of postprocedural bleeding-free events and the other outcomes were estimated alongside 95% confidence intervals (CIs). RESULTS Of seven included RCTs (n = 421; 72.2% men; mean age 49.1 years), VET-guided transfusion did not change postprocedural bleeding-free statuses (RR 1.05; 95% CI 0.94-1.17). However, VET-based algorithms decreased the rates of fresh frozen plasma (FFP; RR 0.52; 95% CI 0.35-0.77) and platelet transfusions (RR 0.34; 95% CI 0.16-0.73), the quantities of transfused FFP (MD -1.39 units; 95% CI -2.18 to -0.60), platelets (MD -1.06 units; 95% CI -2.01 to -0.12) and cryoprecipitate (MD -7.13 units; 95% CI -14.20 to -0.07) and the risk of TRAEs (RR 0.42; 95% CI 0.27-0.65). The overall mortality rates and LOS were not significantly different between two groups. CONCLUSION Compared with conventional SCT-guided, VET-guided strategy decreases periprocedural plasma and platelet transfusions and TRAEs, without increasing haemorrhagic complications, LOS or mortality in cirrhosis.

Abstract
Background/Aims The Thai Association for Gastrointestinal Endoscopy published recommendations on safe endoscopy during the coronavirus disease 2019 (COVID-19) pandemic. This study aimed to assess the practicality and applicability of the recommendations and the perceptions of endoscopy personnel on them.
Methods A validated questionnaire was sent to 1290 endoscopy personnel globally. Of these, the data of all 330 responders (25.6%) from 15 countries, related to the current recommendations on proper personal protective equipment (PPE), case selection, scope cleaning, and safety perception, were analyzed. Ordinal logistic regression was used to determine the relationships between the variables.
Results Despite an overwhelming agreement with the recommendations on PPE (94.5%) and case selection (95.5%), their practicality and applicability on PPE recommendations and case selection were significantly lower (p=0.001, p=0.047, p<0.001, and p=0.032, respectively). Factors that were associated with lower sense of safety in endoscopy units were younger age (p=0.004), less working experience (p=0.008), in-training status (p=0.04), and higher national prevalence of COVID-19 (p=0.003). High prevalent countries also had more difficulty implementing the guidelines (p<0.001) and they considered the PPE recommendations less practical and showed lower agreement with them (p<0.001 and p=0.008, respectively). A higher number of in-hospital COVID-19 patients was associated with less agreement with PPE recommendations (p=0.039). Conclusions Using appropriate PPE and case selection in endoscopic practice during a pandemic remains a challenge. Resource availability and local prevalence are critical factors influencing the adoption of the current guidelines.

Abstract
BACKGROUND AND AIM During the Coronavirus Disease 2019 pandemic, esophagogastroduodenoscopy (EGD) has been recognized as an aerosol-generating procedure. This study aimed to systematically compare the degree of face shield contamination between endoscopists who performed EGD on patients lying in the left lateral decubitus (LL) and prone positions. METHODS This is a randomized trial in patients scheduled for EGD between April and June 2020. Eligible 212 patients were randomized with 1:1 allocation. Rapid adenosine triphosphate test was used to determine contamination level using relative light units of greater than 200 as a cutoff value. All eligible patients were randomized to lie in either the LL or prone position during EGD. The primary outcome was the rate of contamination on the endoscopist's face shield. RESULTS The majority of patients were female (63%), with a mean age of 60 ± 13 years. Baseline characteristics were comparable between the two groups. There was no face shield contamination after EGD in either group. The number of coughs in the LL group was higher than the prone group (1.38 ± 1.8 vs 0.89 ± 1.4, P = 0.03). The mean differences in relative light units on the face shield before and after EGD in the LL and prone groups were 9.9 ± 20.9 and 4.1 ± 6 (P = 0.008), respectively. CONCLUSION As measured by the adenosine triphosphate test, performing diagnostic EGD does not lead to contamination on the face shield of the endoscopist. However, placing patients in the prone position may further mitigate the risk.

Abstract
BACKGROUND Per-oral cholangioscopy (POC) has evolved over the past decade from fiberoptic to digital and video imaging systems. Nowadays, only direct per-oral cholangioscopy (DPOC) and digital single-operator cholangioscopy (DS) are performed in daily practice. With better image resolution, POC is increasingly used as diagnostic tools in patients with suspected malignant biliary stricture (MBS). We aimed to evaluate the diagnostic yield of digital/video cholangioscopes for the diagnosis of MBS. METHODS A systematic search was performed in MEDLINE, Embase, and ISI Web of Knowledge databases until April 2020, to identify randomized controlled trials and prospective studies using digital or video POC. The meta-analysis of diagnostic accuracy study was performed to calculate summary estimates of the primary outcomes, including pooled sensitivity, and specificity of POC to diagnose MBS using bivariate random-effects models. Tissue histopathology was used as the reference standard for MBS diagnosis. For benign stricture, negative tissue histopathology and at least 6 months clinical follow-up were required. RESULTS Thirteen original articles with 876 patients were identified. The overall pooled sensitivity and specificity were 88 (95% CI 83-91) and 95 (95% CI 89-98), respectively. The area under the curve (AUROC) was 0.94 (95% CI 0.92-0.96). Subgroup analysis showed that cholangioscopic image impression provided significantly higher sensitivity (93% (95% CI 88-96) vs 82% (95% CI 76-87); p = 0.007), but lower specificity 86% (95% CI 75-92) vs 98 (95% CI 95-99); p < 0.001) than the tissue diagnosis from cholangioscopic-guided biopsy. In addition, biopsy obtained from DPOC had significantly higher sensitivity than that of DS (92% (95% CI 81-97) vs 79% (95% CI 72-84); p = 0.004). Diagnostic performance under image-enhanced endoscopy was not significantly better from white light endoscopy. CONCLUSIONS Digital/video POC has very high diagnostic performance to diagnose MBS. While image diagnosis provides higher sensitivity than biopsy, its specificity drops as a trade-off.

Abstract
BACKGROUND AND AIMS As on-call anesthesiologist administered propofol sedation (OAPS) is costly and not readily available in all endoscopy units, endoscopy nurse administered propofol sedation (NAPS) can be an effective alternative. This study aimed to compare the dosage of propofol used by NAPS versus OAPS, cardiopulmonary adverse events and recovery time in low risk patients undergoing outpatient elective colonoscopy. METHODS A retrospective propensity score-matched cohort study was conducted. Electronic medical records of elective colonoscopies performed by 3 experienced endoscopists from January 2016 to December 2019 were retrieved. OAPSs were performed by 10 certified anesthesiologists while NAPSs were performed by 8 experienced registered endoscopy nurses. Baseline characteristics, performing endoscopist, cecal intubation time, withdrawal time, propofol dosage per procedure, and adverse events were collected and analyzed using 3:1 (NAPS:OAPS) propensity score matching by age, performing endoscopist and difficulty of colonoscopy as co-variates with standardized mean deviation of <0.1. RESULTS 278 eligible patients were included. After propensity score matching, there were 189 patients in NAPS and 63 in OAPS group for analysis. Demographic data were not different between the two groups. All procedures were technically successful with no difference in cecal intubation time (6.0±4 min vs 6.8±4 min; p=0.13) or total procedural time (17.2±16 min vs 16.3±6 min; p=0.66). Propofol dosage/kg/hour were significantly lower in the NAPS group, (11.4±4 mg/kg/hour vs. 16.6±8 mg/kg/hour; p<0.001). There were less minor cardiopulmonary adverse events in NAPS when compared to the OAPS group (2.2% vs 4.7%; p=0.014). CONCLUSIONS NAPS in elective colonoscopy in low-risk patients is as effective as OAPS but requires a significant lower dosage of propofol. Minor cardiopulmonary adverse events were recorded in the NAPS group compared to OAPS.

Abstract
BACKGROUND Cholangioscopy provides direct intraductual imaging, which can enhance diagnostic efficacy during endoscopic retrograde cholangiopancreatography in patients with biliary strictures. This study aimed to review the diagnostic yield of different cholangioscopes for the diagnosis of malignant biliary stricture (MBS). METHODS A comprehensive literature review was performed. Full papers of prospective studies using any type of peroral cholangioscope (POC) were included without language restriction. The primary outcomes were sensitivity, specificity, and accuracy of various POCs to diagnose MBS. RESULTS Data from 20 published articles, involving 1141 patients, were extracted. Overall sensitivities of POCs for diagnosing MBS were higher for the diagnosis made under visual impression compared with those from cholangioscopy-guided biopsy (67 % - 100 % vs. 38 % - 100 %), whereas the overall specificities were generally high and comparable (73 % - 100 % vs. 75 % - 100 %). Newer video cholangioscopes (digital single-operator POC [digital SOC], direct POC) with the exception of video dual-operator mother - baby POC (video DOC), provided better sensitivity of cholangioscopy-guided biopsy compared with fiberoptic scopes (digital SOC 80 % - 85 %, direct POC 80 % - 100 %, video DOC 38 % - 100 %, and fiberoptic SOC 49 % - 100 %, respectively). Among these video cholangioscopes, the digital SOC provided the highest technical success rate, at 100 %. CONCLUSIONS POCs enhanced the diagnostic yield for diagnosis of MBS. Compared with fiberoptic POCs that only provide good image impression, the digital SOC and direct POC were good at both image impression and cholangioscopy-guided biopsy to diagnose MBS. To ensure high technical success for MBS diagnosis, the digital SOC is a good option.

Abstract
BACKGROUND & AIMS Altering the intestinal microbiota has been proposed as a treatment for inflammatory bowel diseases (IBDs), but there are no established associations between specific microbes and IBD. We performed a systematic review to identify frequent associations. METHODS We searched the MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials databases, through April 2, 2018 for studies that compared intestinal microbiota (from fecal or colonic or ileal tissue samples) among patients (adult or pediatric) with IBD vs healthy individuals (controls). The primary outcome was difference in specific taxa in fecal or intestinal tissue samples from patients with IBD vs controls. We used the Newcastle-Ottawa scale to assess the quality of studies included in the review. RESULTS We identified 2631 citations; 48 studies from 45 articles were included in the analysis. Most studies evaluated adults with Crohn's disease or ulcerative colitis. All 3 studies of Christensenellaceae and Coriobacteriaceae and 6 of 11 studies of Faecalibacterium prausnitzii reported a decreased amount of those organisms compared with controls, whereas 2 studies each of Actinomyces, Veillonella, and Escherichia coli revealed an increased amount in patients with Crohn's disease. For patients with ulcerative colitis, Eubacterium rectale and Akkermansia were decreased in all 3 studies, whereas E coli was increased in 4 of 9 studies. The microbiota diversity was either decreased or not different in patients with IBD vs controls. Fewer than 50% of the studies stated comparable sexes and ages of cases and controls. CONCLUSIONS In a systematic review, we found evidence for differences in abundances of some bacteria in patients with IBD vs controls, but we cannot make conclusions due to inconsistent results and methods among studies. Further large-scale studies, with better methods of assessing microbe populations, are needed.

Abstract
BACKGROUND AND AIM Long-term use of dual antiplatelets is increasing, and most patients need primary peptic ulcer prophylaxis. The long-term use of proton pump inhibitors (PPIs) is associated with adverse events. We evaluated the efficacy of rebamipide for peptic ulcer prevention. METHODS This randomized controlled trial was conducted between July 2014 and November 2017. Patients receiving dual antiplatelets for ≥ 1 year with no history of peptic ulcer bleeding or perforation were recruited and randomly assigned to the rebamipide (300 mg/day) group or the placebo group. Patients who used proton pump inhibitors were excluded. The primary endpoint was a new mucosal break on esophagogastroduodenoscopy at 3 or 12 months after treatment initiation. The secondary endpoints were hematocrit changes from the baseline, gastrointestinal bleeding, and chest pain. Antiplatelet function was assessed. RESULTS In total, 95 eligible patients were identified; 12 were excluded, and 83 patients were randomized, with 66 (79.5%) and 59 (71.1%) patients eligible at the 3- and 12-month follow ups, respectively. The baseline characteristics were equivalent between the groups. During the 12 months of follow up, 13 patients (43.3%) taking rebamipide and 19 (65.5%) taking the placebo experienced mucosal injury (P = 0.07). Two patients (6.7%) taking rebamipide and eight (27.6%) taking the placebo had peptic ulcers ≥ 5 mm or < 5 mm with pigmented spots (P = 0.03). The changes in hematocrit were not different between the two groups. Neither bleeding ulcers nor chest pain was observed. CONCLUSION Rebamipide is safe and may prevent peptic ulcers ≥ 5 mm in diameter or those with pigmented spots in patients receiving dual antiplatelets for 1 year (NCT02166008).

Abstract
BACKGROUND & AIMS Irritable bowel syndrome (IBS) is common but difficult to treat. Altering the gut microbiota has been proposed as a strategy for treatment of IBS, but the association between the gut microbiome and IBS symptoms has not been well established. We performed a systematic review to explore evidence for this association. METHODS We searched databases, including MEDLINE, EMBASE, Cochrane CDSR, and CENTRAL, through April 2, 2018 for case-control studies comparing the fecal or colon microbiomes of adult or pediatric patients with IBS with microbiomes of healthy individuals (controls). The primary outcome was differences in specific gut microbes between patients with IBS and controls. RESULTS The search identified 2631 citations; 24 studies from 22 articles were included. Most studies evaluated adults presenting with various IBS subtypes. Family Enterobacteriaceae (phylum Proteobacteria), family Lactobacillaceae, and genus Bacteroides were increased in patients with IBS compared with controls, whereas uncultured Clostridiales I, genus Faecalibacterium (including Faecalibacterium prausnitzii), and genus Bifidobacterium were decreased in patients with IBS. The diversity of the microbiota was either decreased or not different in IBS patients compared with controls. More than 40% of included studies did not state whether cases and controls were comparable (did not describe sex and/or age characteristics). CONCLUSIONS In a systematic review, we identified specific bacteria associated with microbiomes of patients with IBS vs controls. Studies are needed to determine whether these microbes are a product or cause of IBS.

Abstract
OBJECTIVES In the management of patients with bleeding peptic ulcers, recurrent bleeding is associated with high mortality. We investigated if added angiographic embolisation after endoscopic haemostasis to high-risk ulcers could reduce recurrent bleeding. DESIGN After endoscopic haemostasis to their bleeding gastroduodenal ulcers, we randomised patients with at least one of these criteria (ulcers≥20 mm in size, spurting bleeding, hypotensive shock or haemoglobin<9 g/dL) to receive added angiographic embolisation or standard treatment. Our primary endpoint was recurrent bleeding within 30 days. RESULTS Between January 2010 and July 2014, 241 patients were randomised (added angiographic embolisation n=118, standard treatment n=123); 22 of 118 patients (18.6%) randomised to angiography did not receive embolisation. In an intention-to-treat analysis, 12 (10.2%) in the embolisation and 14 (11.4%) in the standard treatment group reached the primary endpoint (HR 1.14, 95% CI 0.53 to 2.46; p=0.745). The rate of reinterventions (13 vs 17; p=0.510) and deaths (3 vs 5, p=0.519) were similar. In a per-protocol analysis, 6 of 96 (6.2%) rebled after embolisation compared with 14 of 123 (11.4%) in the standard treatment group (HR 1.89, 95% CI 0.73 to 4.92; p=0.192). None of 96 patients died after embolisation compared with 5 (4.1%) deaths in the standard treatment group (p=0.108). In a posthoc analysis, embolisation reduced recurrent bleeding only in patients with ulcers≥15 mm in size (2 (4.5%) vs 12 (23.1%); p=0.027). CONCLUSIONS After endoscopic haemostasis, added embolisation does not reduce recurrent bleeding. TRIAL REGISTRATION NUMBER NCT01142180.

Abstract
BACKGROUND This is a consensus developed by a group of expert endoscopists aiming to standardise the preparation, process and endoscopic procedural steps for diagnosis of early upper gastrointestinal (GI) cancers. METHOD The Delphi method was used to develop consensus statements through identification of clinical questions on diagnostic endoscopy. Three consensus meetings were conducted to consolidate the statements and voting. We conducted a systematic literature search on evidence for each statement. The statements were presented in the second consensus meeting and revised according to comments. The final voting was conducted at the third consensus meeting on the level of evidence and agreement. RESULTS Risk stratification should be conducted before endoscopy and high risk endoscopic findings should raise an index of suspicion. The presence of premalignant mucosal changes should be documented and use of sedation is recommended to enhance detection of superficial upper GI neoplasms. The use of antispasmodics and mucolytics enhanced visualisation of the upper GI tract, and systematic endoscopic mapping should be conducted to improve detection. Sufficient examination time and structured training on diagnosis improves detection. Image enhanced endoscopy in addition to white light imaging improves detection of superficial upper GI cancer. Magnifying endoscopy with narrow-band imaging is recommended for characterisation of upper GI superficial neoplasms. Endoscopic characterisation can avoid unnecessary biopsy. CONCLUSION This consensus provides guidance for the performance of endoscopic diagnosis and characterisation for early gastric and oesophageal neoplasia based on the evidence. This will enhance the quality of endoscopic diagnosis and improve detection of early upper GI cancers.

Abstract
The management of dyspepsia in limited-resource areas has not been established. In 2017, key opinion leaders throughout Thailand gathered to review and evaluate the current clinical evidence regarding dyspepsia and to develop consensus statements, rationales, levels of evidence, and grades of recommendation for dyspepsia management in daily clinical practice based on the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. This guideline is mainly focused on the following 4 topics: (1) evaluation of patients with dyspepsia, (2) management, (3) special issues (overlapping gastroesophageal reflux disease/irritable bowel syndrome and non-steroidal anti-inflammatory drug/aspirin use), and (4) long-term follow-up and management to provide guidance for physicians in Thailand and other limited-resource areas managing such patients.

Abstract
BACKGROUND Currently, it is still unclear whether adding a mucoprotective agent to a proton pump inhibitor (PPI) results in better outcomes compared with using a PPI alone in patients with post-gastric endoscopic submucosal dissection (ESD) ulcers. This study aimed to examine the efficacy of PPI alone versus combination treatment in healing of post-gastric ESD ulcers, as well as on delayed bleeding and amount of blood transfused. METHODS A systematic search of MEDLINE, EMBASE, Cochrane, and ISI Web of knowledge databases, up until May 2017, for randomized trials comparing PPI alone versus PPI plus a mucoprotective drug in achieving ulcer healing in patients undergoing gastric ESD was performed. The primary outcome is scarring stage on endoscopic assessment at 4 or 8 weeks after gastric ESD. RESULTS From an initial 3071 citations, eight articles (n = 953 lesions from 934 patients) were analyzed. Patients receiving combination treatment achieved a scarring stage significantly more often than those on a PPIs alone at 4 or 8 weeks after ESD, (risk ratio = 1.36, 95% CI; 1.06-1.75). No study reported amount of blood transfused. There were no significant between treatment-group differences in terms of delayed bleeding (risk ratio = 0.58, 95% CI; 0.17-1.99). Neither location of ulcer nor Helicobacter pylori infection was related to ulcer scarring stage. CONCLUSION The limited evidences suggested combination treatment may be more effective in accelerating the process of ulcer healing in patients undergoing gastric ESD than the use of PPI alone, but does not appear to alter delayed bleeding risk.

Abstract
BACKGROUND Dyspepsia is a common condition associated with gastrointestinal (GI) disease. Prokinetics are the treatment of choice for functional dyspepsia (FD). However, the role of prokinetics in FD treatment is still controversial. OBJECTIVES We conducted a systematic review and meta-analysis of randomised control trials (RCTs) examining the efficacy of prokinetics in the treatment of FD. The primary outcome was overall absence of or improvement of symptoms and symptom scores at the end of treatment. We also evaluated quality of life (QoL) and adverse events as secondary outcomes. SEARCH METHODS We performed a systematic search of MEDLINE, Embase, the Cochrane Library, and CINAHL, from 1946 until September 2017. RevMan 5.3 was used to calculate pooled risk ratios (RR) of symptoms persisting or without improved QoL or adverse events, mean difference (MD) or standardised mean difference (SMD) of post-treatment symptoms scores, changes of symptom scores, and QoL, when appropriate with 95% confidence intervals (CI), using a random-effects model. Quality of evidence was evaluated using GRADE methodology. SELECTION CRITERIA We included studies that were parallel group RCTs comparing one prokinetic with either placebo or another prokinetic of the same or different class for the treatment of FD. Studies involved adults who presented with dyspepsia symptoms and who had negative or insignificant findings on endoscopy as well as no other organic and metabolic disorders. Studies only including participants with primarily reflux or heartburn symptoms were excluded. DATA COLLECTION AND ANALYSIS Two review authors independently assessed study eligibility, study quality and performed data extraction. MAIN RESULTS From an initial 1388 citations, we identified 43 studies in 40 papers. Of those, 29 studies with 10,044 participants compared six prokinetics with placebo for the outcome of absence of symptoms or symptom improvement. There was a statistically significant effect of prokinetic treatment in reducing global symptoms of FD (RR of remaining dyspeptic = 0.81, 95% CI 0.74 to 0.89; number needed to treat for an additional beneficial outcome (NNTB) =7, very low-quality evidence) with considerable heterogeneity; I2 = 91% (P < 0.00001). After removing cisapride from the analysis, the effect of prokinetics in global symptom improvement still persisted, compared to placebo (RR 0.87, 95% CI 0.80 to 0.94), but was still based on very low-quality evidence. The result showed persistence of significant improvement in subgroups of studies at unclear or at low risk of bias (RR 0.86, 95% CI 0.80-0.92), and in subgroups by molecules of cisapride (RR 0.71, 95% CI 0.54 to 0.93; NNTB = 4), acotiamide (RR 0.94, 95% CI 0.91 to 0.98; NNTB = 20) and tegaserod(RR 0.89, 95% CI 0.82 to 0.96; NNTB = 14).Ten studies compared different types of prokinetics with each other and the most commonly used comparator was domperidone, 10 mg three times a day (eight of the 10 studies). There was a significantly better post-treatment symptom score in other prokinetics, compared to domperidone (SMD -0.19, 95% CI -0.35 to -0.03, very low-quality evidence), but no difference in reducing global symptom (RR 0.94, 95% CI 0.83 to 1.07), and mean difference symptom scores (SMD -0.13, 95% CI -0.31 to 0.05). We found five studies that assessed quality of life, but there was no benefit in improving quality of life with prokinetic treatment (SMD 0.11, 95% CI -0.10 to 0.33; participants = 1774). The adverse events in individual prokinetics was not different from placebo (RR 1.09, 95% CI 0.95 to 1.25; participants = 3811; studies = 17). However, when we looked at the adverse effects by each prokinetic, there were overall greater adverse effects in the active treatment group with cisapride (RR 1.31, 95% CI 1.03 to 1.65; P = 0.03). The most common side effects were diarrhoea, abdominal discomfort and nausea. The funnel plot was asymmetric (Egger's test, P = 0.02) implying reporting bias or other small-study effects may be, in part, driving the benefit of prokinetics compared to placebo in this meta-analysis. The GRADE assessment of the quality of the evidence in each outcome are mostly low or very low due to concerns around risk of bias in study design, unexplained heterogeneity and possible publication bias. AUTHORS' CONCLUSIONS Due to low, or very low, quality of evidence, we are unable to say whether prokinetics are effective for the treatment of functional dyspepsia . We are uncertain which of the individual prokinetic drugs is the most effective as well as whether prokinetics can improve quality of life. Apart from cisapride, prokinetics are well-tolerated. Good quality RCTs are needed to verify the efficacy of prokinetics.

Abstract
Background/Aims This study aimed to evaluate the diagnostic accuracy of dual-focus narrow-band imaging (dNBI) and Lugol’schromoendoscopy (LCE) combined with probe-based confocal laser endomicroscopy (pCLE) to screen for esophageal squamous cell neoplasms (ESCNs) in patients with a history of head and neck cancer.
Methods From March to August 2016, dNBI was performed. Next, LCE was performed, followed by pCLE and biopsy. Histology has historically been the gold standard to diagnose ESCN. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of dNBI and LCE adjunct with pCLE were determined.
Results Twenty-four patients were included. Ten ESCNs were found in 8 patients (33%). Forty percent of high-graded intraepithelial neoplasias and all low-grade intraepithelial neoplasias were overlooked by dNBI. The sensitivity, specificity, PPV, NPV, and accuracy of dNBI vs. LCE combined with pCLE were 50% vs. 80%, 62% vs. 67%, 36% vs. 44%, 75% vs. 91%, and 83% vs. 70%, respectively.
Conclusions The use of dNBI to detect ESCN was suboptimal. LCE with pCLE following dNBI had additional value for detecting esophageal dysplasia not detected by dNBI. The use of pCLE to detect dNBI-missed lesions yielded a high NPV, while pCLE-guided biopsy could reduce the number of unnecessary biopsies.

Abstract
Background and aim: Thailand and Japan have high prevalence of Helicobacter pylori infection but prevalence of gastric cancer and mortality rate are difference. Most international comparative studies are epidemiologic studies and the difference in actual clinicopathological data has not been clarified. This study aimed to investigate the difference in clinicopathological characteristics of gastric adenocarcinoma between Thailand and Japan.Methods: This retrospective study was conducted in two high-volume hospitals for gastric cancer in Thailand and Japan. Baseline characteristics, clinical manifestations, tumor characteristics, treatments and mortality rate of gastric cancer patients in the two institutions were examined.Results: A total of 403 Thai and 2,318 Japanese patients were retrieved from the electronic database. Finally, 332 Thai and 414 Japanese patients (randomly sampled) with gastric adenocarcinoma were eligible for analysis. Thai gastric adenocarcinoma patients were significantly younger than the Japanese (59 ± 13 vs. 68 ±10 years old, p<0.001) and the majority of Thai patients were female (55% vs. 25%, p<0.001). The rate of smoking (5.1% vs. 23%, p<0.001) and alcohol drinking (2.7% vs. 34%, p<0.001) were lower in Thai patients when compared with those in Japanese. The mortality rate at the conclusion of this study (July 2016) was significantly higher in Thai patients (75.3% vs. 7%, p<0.001). In multivariate analysis, ethnicity, clinical UICC stage II-IV compared to I, and resection-based treatment were significant prognostic factors after adjusting for age, gender, presence of alarm symptom, lesion extension and histology.Conclusion: Thai patients with gastric adenocarcinoma were different from Japanese patients in all aspects. Advanced stage of disease, country, and un-resected tumor were associated with poor prognosis. An individual strategy to improve survival of gastric adenocarcinoma in a low-prevalence area such as Thailand should be explored.

Abstract
BACKGROUND AND AIMS Endoscopic hemostatic techniques remain poorly effective for GI tumor bleeding. We assessed Tc-325 (Hemospray, Cook Medical, Bloomington, Ind, USA) for this indication and determined possible predictors of decreased recurrent bleeding and improved 6-month survival in affected patients. METHODS This retrospective study identified 99 patients with active malignant GI bleeding (primary or metastatic) treated with Tc-325. Eleven patients were excluded because of incomplete data. Data on patient characteristics and possible predictive factors of early (72-hour) and delayed (7-, 14-, and 30-day) recurrent bleeding, as well as 6-month survival, were collected. RESULTS Overall, 70.5% were male (age, 65 ± 14 years). Half had a high Eastern Cooperative Oncology Group (ECOG) score (3 or 4). An upper GI cancer was found in 56.8%, and 72.7% cancers were stage 4. Of those affected, 51.6% received at least 1 non-endoscopic additional definitive hemostatic treatment after Tc-325. Immediate hemostasis with Tc-325 was 97.7%, with recurrent bleeding noted in 15% (early) and 17% (delayed). Six-month survival was 53.4%. On multivariable analysis, no predictive factor for recurrent bleeding was identified, whereas ECOG score 0 to 2 (P = .001; hazard ratio [HR], 0.14; 95% confidence interval [CI], 0.04-0.47), cancer stage 1 to 3 (P = .04; HR, 0.31; 95% CI, 0.10-0.96), and receiving definite hemostatic treatment alone or in any combination with surgery, chemotherapy, radiotherapy, or radiologic embolization (P = .002; HR, 0.24; 95% CI, 0.09-0.59) were significant prognosticators of 6-month survival after adjusting for comorbidity, type of cancer bleeding, and presence of a coagulopathy. CONCLUSION Before definitive therapy can be offered, Tc-325 provides effective initial hemostasis of tumoral GI bleeding. Good performance status, non-end-stage cancer, and receiving definite hemostatic treatment are independent predictors of 6-month survival. (Clinical trial registration number: NCT03066700.).

Abstract
Helicobacter pylori (H. pylori) infection remains to be the major cause of important upper gastrointestinal diseases such as chronic gastritis, peptic ulcer, gastric adenocarcinoma, and mucosa-associated lymphoid tissue lymphoma. H. pylori management in ASEAN: the Bangkok consensus report gathered key opinion leaders for the region to review and evaluate clinical aspects of H. pylori infection and to develop consensus statements, rationales, and grades of recommendation for the management of H. pylori infection in clinical practice in ASEAN countries. This ASEAN Consensus consisted of 34 international experts from 10 ASEAN countries, Japan, Taiwan, and the United States. The meeting mainly focused on four issues: (i) epidemiology and disease association; (ii) diagnostic tests; (iii) management; and (iv) follow-up after eradication. The final results of each workshop were presented for consensus voting by all participants. Statements, rationale, and recommendations were developed from the available current evidence to help clinicians in the diagnosis and treatment of H. pylori and its clinical diseases.

Abstract
BACKGROUND Gastric intestinal metaplasia (GIM) is the premalignant stage of gastric cancer; however, consensus on its management has not been established. AIM To determine the risk factors for gastric cancer in a population of patients with GIM to guide the appropriate clinical recommendations in a low prevalence area for gastric cancer. METHODS This was a retrospective cohort study. Ninety-one patients with GIM diagnosed between 2004 and 2014 were recruited for surveillance EGD every 6-12 months until a diagnosis of gastric cancer or completion of the planned 5-year follow-up duration. Possible risk factors for gastric cancer were assessed. RESULTS At initial presentation, 81 of the 91 patients (89%) had complete GIM, whereas the remaining 11% had a study entry diagnosis of incomplete GIM. No cancer developed amongst patients with complete GIM. In contrast, five of the 10 patients exhibiting incomplete GIM (50%) progressed to high-grade dysplasia (n=2) or cancer (n=3). Male gender (P=.027), and incomplete GIM (P=.001) were associated with high-risk histology (dysplasia or cancer) by study end. A trend suggested a possible association with smoking (P=.08). CONCLUSION Male patients and those with incomplete GIM are at greatest risk of developing dysplasia or early gastric cancer. Further studies in determining optimal surveillance intervals and impact on cancer incidence and mortality are still required.

Abstract
BACKGROUND AND STUDY AIMS Currently, conventional endoscopic treatments provide an unsatisfactory hemostatic outcome in upper gastrointestinal bleeding from tumor. Hemospray has been shown to be useful in many active gastrointestinal bleeding conditions. This study aimed to compare the efficacy of Hemospray and conventional endoscopic hemostasis. PATIENTS AND METHODS Fourteen patients with active upper gastrointestinal bleeding from tumor were recruited. Hemospray was applied at the bleeding site until hemostasis was achieved. Four patients were excluded because they prematurely received definitive therapy to prevent further bleeding within 48 hours. Another 10 patients from historical control were matched based on the type of gastrointestinal tumors. The 14-day rebleeding rates, length of hospital stay (LOS) and mortality rate at 30-day follow up were assessed. RESULTS Baseline characteristics including age, stage of tumor, and Blatchford score did not differ between the two groups. The 14-day rebleeding rate in the Hemospray group was 3 times lower than the control group but not statistically significant (10 % vs. 30 %; P = 0.60). LOS was no different between the 2 groups (28.2 ± 21.2 vs. 23.8 ± 12.5 days; P = 0.26). The 30-day mortality rate in the Hemospray group was 3 times lower than that of in the conventional therapy group but not significant (10 % vs. 30 %, P = 0.7). CONCLUSIONS Hemospray is a promising therapy for initial hemostasis in upper gastrointestinal bleeding from tumor because it can achieve hemostasis during the first 14 days, thus potentially allowing sufficient time before appropriate definitive intervention is considered.

Abstract
Background In many countries, gastric cancer is not diagnosed until an advanced stage. An Internet-based e-learning system to improve the ability of endoscopists to diagnose gastric cancer at an early stage was developed and was evaluated for its effectiveness. Methods The study was designed as a randomized controlled trial. After receiving a pre-test, participants were randomly allocated to either an e-learning or non-e-learning group. Only those in the e-learning group gained access to the e-learning system. Two months after the pre-test, both groups received a post-test. The primary endpoint was the difference between the two groups regarding the rate of improvement of their test results. Findings 515 endoscopists from 35 countries were assessed for eligibility, and 332 were enrolled in the study, with 166 allocated to each group. Of these, 151 participants in the e-learning group and 144 in the non-e-learning group were included in the analysis. The mean improvement rate (standard deviation) in the e-learning and non-e-learning groups was 1·24 (0·26) and 1·00 (0·16), respectively (P < 0·001). Interpretation This global study clearly demonstrated the efficacy of an e-learning system to expand knowledge and provide invaluable experience regarding the endoscopic detection of early gastric cancer (R000012039). This report establishes that an e-learning system on the Internet can improve the diagnostic ability of endoscopists. Countless endoscopists worldwide can access the system to learn how to make an endoscopic diagnosis of early gastric cancer. The e-learning system could be modified to provide education regarding endoscopic diagnosis in other organs.
This is the first report to demonstrate how an e-learning system based on the Internet can improve the diagnostic ability of gastrointestinal endoscopists worldwide. There is no limit to the number of endoscopists who can access the system and benefit from this opportunity to learn how to make an endoscopic diagnosis of early gastric cancer. This e-learning system could be modified to provide education regarding endoscopic diagnosis in other organs such as the large intestine and the esophagus, as well as the stomach. It may contribute to human welfare and health by reducing the mortality from gastrointestinal cancer.

Abstract
BACKGROUND AND STUDY AIMS Endoscopic ultrasound-guided needle-based confocal laser endomicroscopy (EUS-nCLE) has been shown to aid in the diagnosis of cystic pancreatic lesions. This is a pilot project to study its findings in patients with solid pancreatic lesions (SPLs) with a prospective single-blinded study design. METHODS Patients with SPLs undergoing trans-gastric EUS fine needle aspiration (EUS-FNA) from July 2013 to March 2014 were prospectively enrolled. The nCLE diagnoses were compared with the final diagnoses. Researchers learned about the EUS-nCLE findings from previously published studies and applied it to diagnose SPLs. In the meantime, the findings were recorded. RESULTS In total, 22 patients were recruited (mean age 62.7 years, SD 13.8 years; 14 men and eight women). The mean maximal tumor diameter was 36.0 mm (SD 10.9 mm). EUS-nCLE yielded satisfactory images in all patients during the first EUS procedure and diagnosed benign and malignant SPLs in 3 and 19 patients, respectively. Final diagnoses of malignant SPLs were made in 19 patients. Benign SPLs were eventually diagnosed in three patients, with confirmed the cytology and disease stability during the 12-month follow-up period. At the end of the project, based on the results of this current study, EUS-nCLE findings for malignant SPLs were dark clumping with or without dilated vessels (> 40 μm). There were two criteria for diagnosing benign lesions which were white fibrous bands and normal acini cells. The accuracy rate of EUS-nCLE was 90.9 % (20/22). One falsely diagnosed malignant SPL was an inflammatory mass from a recent acute pancreatitis. Another one with a pancreatic neuroendocrine tumor presenting with a symptomatic pseudocyst was incorrectly diagnosed as an inflammatory mass. This was likely from sampling error of the EUS-nCLE probe in an inflammatory area. Only one patient had post EUS-FNA bleeding but did not require a blood transfusion. The inter-observer agreement among three blinded endoscopists was almost perfect (Kappa 0.82). CONCLUSION EUS-nCLE is a promising technique for the diagnosis of SPLs with good inter-observer agreement. Study registration: TCTR20140402001.

Abstract
Management of Helicobacter pylori infection is an important aspect of many upper gastrointestinal tract diseases, such as chronic gastritis, peptic ulcer disease, gastric cancer and mucosa-associated lymphoid tissue (MALT) lymphoma. The Thailand Consensus on H. pylori treatment 2015 consisted of 22 national experts who took active roles, discussed all important clinical information and investigated clinical aspects in four workshops, focuising on: (1) Diagnosis (2) Treatment (3) Follow-up after eradication and (4) H. pylori infection and special conditions. Experts were invited to participate on the basis of their expertise and contribution to H. pylori works and/or consensus methodology. The results of each workshop were taken to a final consensus vote by all experts. Recommendations were developed from the best evidence and availability to guide clinicians in management of this specific infection associated with variety of clinical outcomes.

Abstract
BACKGROUND Negative results of EUS-FNA for solid pancreatic lesions (SPL) can be false ones. Combination with strain ratio (SR) may ensure a correct benign diagnosis of SPL. AIMS We prospectively evaluated the sensitivity rate of EUS-FNA and EUS elastography using the strain ratio method for diagnosing SPL. METHODS Thirty-eight patients with SPL identified by CT or MRI between January 2013 and November 2013 were included in our prospective study. EUS diagnoses were made using SR by an endosonographer who was blinded to all clinical information. In SPL with adequate cellularity, the results of EUS-FNA were combined with strain ratio to diagnose SPL and the diagnostic value was calculated. RESULTS Benign SPL were diagnosed in nine patients with surgical or guided-biopsy pathology (n = 3) and benign cells from FNA with stable disease during the 12-month follow-up time (n = 6). Using the best cut-off strain ratio level at 3.17, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy rate of EUS elastography were 86.2%, 66.7%, 89.3%, 60%, and 81.6%, respectively. For the 28 patients who underwent EUS-FNA with results of adequate cellularity; EUS-FNA alone versus combination of results of cytology and SR provided sensitivity, specificity, PPV, NPV, and accuracy rate at 90% versus 95.2, 100% versus 71.4%, 100% versus 90.9%, 80% versus 83.3, and 92.9% versus 89.3%, respectively. CONCLUSIONS In this prospective single-blinded study, the negative results of both EUS-FNA and SR were more reliable to exclude malignant SPL. The sensitivity of EUS elastography by SR was not superior to EUS-FNA. © 2015 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

Abstract
BACKGROUND AND STUDY AIMS Familial adenomatous polyposis (FAP) is associated with an increased risk of development of periampullary and nonampullary adenoma. Either routine biopsy or endoscopic removal of the lesion is generally required to identify the presence of adenoma. Because the risk of tissue sampling from the ampulla is high and nonampullary polyps are sometimes numerous, resection of all the lesions is time-consuming. This study aimed to evaluate the diagnostic values of duodenal adenoma by dual focus NBI (dNBI) and probe-based confocal endomicroscopy (pCLE) in FAP patients. PATIENTS AND METHODS The authors conducted a diagnostic study in a single tertiary-care referral center. Surveillance esophagogastroduodenoscopy with dNBI and pCLE was performed on 26 patients with FAP for real-time adenoma diagnosis by two different endoscopists; one used dNBI and the other pCLE. Histology from the matched lesion was used as the gold standard. RESULTS A total of 55 matched biopsies (25 ampullas, 30 nonampullas) were performed. The sensitivity, specificity, post predictive value (PPV), negative predictive value (NPV), and accuracy of dNBI vs. pCLE from all duodenal lesions were 96.9 % vs. 93.8 %, 78.3 % vs. 81 %, 86.1 % vs. 88.2 %, 94.7 vs. 89.5 %, and 92.4 % vs. 88.6 %, respectively. CONCLUSIONS For surveillance of periampullary and nonampullary adenoma in patients with FAP, the real-time readings provided a high degree of diagnostic value when histology was used as the gold standard.
