Abstract
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.

Abstract
Pancreatic fluid collections (PFCs) including pancreatic pseudocyst (PP) and walled-off necrosis (WON) are complications after acute pancreatitis. We aimed to evaluate the efficacy and safety of endoscopic ultrasound (EUS)-guided lumen-apposing metal stent (LAMS) placement to manage PFCs. Between June 2019 and May 2023, patients with symptomatic PFCs who underwent EUS-guided electrocautery-enhanced LAMS drainage were enrolled retrospectively from eight tertiary centers in Taiwan. In total, 33 [14 (42.42%) PP and 19 (57.58%) WON] patients were enrolled. Gallstones (27.27%) and abdominal pain (72.73%) were the most common etiology and indication for drainage. The technical and clinical success rates were 100% and 96.97%, respectively, and the mean procedure time was 30.55 (± 16.17) min. Complications included one (3.03%) case of self-limited bleeding; there were no cases of mortality. Seven (21.21%) patients had recurrence. Patients with disconnected pancreatic duct syndrome (DPDS) had a higher recurrence rate than those without (71.43% vs. 38.46%, p = 0.05). After replacing LAMSs with transmural double-pigtail plastic stents (DPSs) in the DPDS patients, the DPS migration rate was higher in the patients with recurrence (100% vs. 33.33%, p = 0.04). In conclusion, drainage of symptomatic PFCs with EUS-guided electrocautery-enhanced LAMS appears to be efficient and safe. Replacing LAMSs with DPSs in DPDS patients was associated with a lower recurrence rate.

Abstract
Crohn disease (CD) is one of the most common causes of short bowel syndrome and intestinal failure. Intestinal transplantation (IT) is sometimes needed for patients with CD who develop intestinal failure after multiple intestinal resections resulting from CD-related complications, such as uncontrollable bleeding and penetrating diseases. However, there have been few case reports concerning the endoscopic surveillance of patients with CD after IT. In this article, we present 2 patients with CD who underwent IT because of short bowel syndrome with intestinal failure. We administered posttransplantation immunosuppressants and conducted regular follow-up magnifying endoscopy with narrow-band imaging (ME-NBI). Both cases demonstrated favorable outcomes after surveillance with ME-NBI. In this report, we outline our post-IT follow-up strategies applying the VENCH scoring system, which is based on endoscopic features using ME-NBI to predict graft rejection. Our approach could effectively distinguish between acute cellular rejection and non-rejection, particularly disease recurrence of underlying CD. This study was approved by the institutional review board of Far Eastern Memorial Hospital (FEMH-105023-F). The patients provided written informed consent for publication.

Abstract
Introduction Patients with head and neck cancer may develop a second primary neoplasm (SPN) of the esophagus due to field cancerization. This study investigated the impacts of esophageal cancer screening using magnifying endoscopy with narrow-band imaging (ME-NBI) on the outcomes of hypopharyngeal cancer patients. Methods Patients with hypopharyngeal cancer diagnosed from 2008 to 2021 in a tertiary hospital were reviewed retrospectively. Screening and surveillance using ME-NBI examination of the esophagus were divided into three patterns: (1) ME-NBI never performed or more than 6 months after diagnosis of index primary hypopharyngeal cancer, (2) ME-NBI within 6 months only, and (3) ME-NBI within 6 months and regular surveillance. Results A total of 261 were reviewed and 21 (8%) patients were in stage I, 20 (8%) in stage II, 27 (10%) in stage III, 116 (44%) in stage IVA, 65 (25%) in stage IVB, and 12 (5%) in stage IVC. Sixty-seven (26%) patients had SPN (50 esophagus, 10 oral cavity, 3 oropharynx, 2 nasopharynx, 1 larynx and 1 lung). Among esophageal SPN, 35 (70%) and 15 (30%) patients developed synchronous and metachronous neoplasia, respectively. In multivariate Cox regression analysis, advanced stages III and IV (compared with stages I and II, HR: 1.86, 1.18-2.95, p=0.008), ME-NBI examination of the esophagus received within 6 months and regular surveillance (HR: 0.53, 0.36-0.78, p=0.001) were independent factors affecting the overall survival of patients with hypopharyngeal cancer. Discussion Our findings demonstrated that screening and surveillance of esophageal SPN by ME-NBI improves the survival of patients with hypopharyngeal cancer.

Abstract
BACKGROUND This nationwide prospective registry study investigated the real-world effectiveness, safety, and persistence of vedolizumab (VDZ) in inflammatory bowel disease (IBD) patients in Taiwan. Disease relapse rates after VDZ discontinuation due to reimbursement restriction were assessed. METHODS Data were collected prospectively (January 2018 to May 2020) from the Taiwan Society of IBD registry. RESULTS Overall, 274 patients (147 ulcerative colitis [UC] patients, 127 Crohn's disease [CD] patients) were included. Among them, 70.7% with UC and 50.4% with CD were biologic-naïve. At 1 year, 76.0%, 58.0%, 35.0%, and 62.2% of UC patients and 57.1%, 71.4%, 33.3%, and 30.0% of CD patients achieved clinical response, clinical remission, steroid-free remission, and mucosal healing, respectively. All patients underwent hepatitis B and tuberculosis screening before initiating biologics, and prophylaxis was recommended when necessary. One hepatitis B carrier, without antiviral prophylaxis due to economic barriers, had hepatitis B reactivation during steroid tapering and increasing azathioprine dosage, which was controlled with an antiviral agent. No tuberculosis reactivation was noted. At 12 months, non-reimbursement-related treatment persistence rates were 94.0% and 82.5% in UC and CD patients, respectively. Moreover, 75.3% of IBD patients discontinued VDZ due to mandatory drug holiday. Relapse rates after VDZ discontinuation at 6 and 12 months were 36.7% and 64.3% in CD patients and 42.9% and 52.4% in UC patients, respectively. CONCLUSIONS The findings demonstrated VDZ effectiveness in IBD patients in Taiwan, with high treatment persistence rates and favorable safety profiles. A substantial IBD relapse rate was observed in patients who had mandatory drug holiday.

Abstract
BACKGROUND The coronavirus disease 2019 (COVID-19) pandemic had a great impact on healthcare system and patients. This study aimed to evaluate the effect of the COVID-19 pandemic on the perceptions of patients with inflammatory bowel disease (IBD). METHODS This prospective multicenter study was conducted between July 2021 and December 2021. Patients with IBD answered a structured questionnaire, and their degree of anxiety was assessed using a visual analogue scale (VAS) before and after reading educational materials. RESULTS A total of 225 (47.67%) patients with Crohn's disease, 244 (51.69%) with ulcerative colitis and 3 (0.64%) with indeterminate colitis were enrolled. Common concerns were adverse events from vaccination (20.34%), and higher risks of developing severe COVID-19 (19.28%) and COVID-19 infection (16.31%) than the general population. Medications deemed by the patients to increase the risk of COVID-19 were immunomodulators (16.10%), anti-tumor necrosis factor-α antagonists (9.96%), and corticosteroids (9.32%). Thirty-five (7.42%) patients self-discontinued IBD medication, of whom 12 (34.28%) had worse symptoms. Older age (>50 years) (OR 1.10, 95% CI 1.01-1.19, p = 0.03), IBD-related complications (OR 1.16, 95% CI 1.04-1.28, p = 0.01), education status below senior high school (OR 1.22, 95% CI 1.08-1.37, p = 0.001), and residing in north-central Taiwan (OR 1.21, 95% CI 1.10-1.34, p < 0.001) were associated with more anxiety. None of the enrolled patients contracted COVID-19. The anxiety VAS score (mean ± SD) improved after reading the educational materials (3.84 ± 2.33 vs. 2.81 ± 1.96, p < 0.001). CONCLUSION The medical behavior of IBD patients was influenced by the COVID-19 pandemic, and their anxiety could be mitigated after education.

Abstract
BACKGROUND Cholangiocarcinoma (CC) is a very aggressive cancer with a poor prognosis. As surgery is the only curative therapy, preoperative evaluation of the tumor extent is essential for surgical planning. Although high-quality image modalities such as computed tomography and magnetic resonance imaging have been used extensively in preoperative evaluation, the accuracy is low. To obtain precise localization of tumor spread arising from the hilar region preoperatively, the development of an acceptable imaging modality is still an unmet need.
CASE SUMMARY A 52-year-old female presented to our emergency department with jaundice, abdominal pain, and fever. Initially, she was treated for cholangitis. Endoscopic retrograde cholangiopancreatography with the cholangiogram showed long segment filling defect in the common hepatic duct with dilatation of bilateral intrahepatic ducts. Transpapillary biopsy was performed, and the pathology suggested intraductal papillary neoplasm with high-grade dysplasia. After treatment of cholangitis, contrasted-enhanced computed tomography revealed a hilar lesion with undetermined Bismuth-Corlette classification. SpyGlass cholangioscopy showed that the lesion involved the confluence of the common hepatic duct with one skip lesion in the posterior branch of the right intrahepatic duct, which was not detected by previous image modalities. The surgical plan was modified from extended left hepatectomy to extended right hepatectomy. The final diagnosis was hilar CC, pT2aN0M0. The patient has remained disease-free for more than 3 years.
CONCLUSION SpyGlass cholangioscopy may have a role in precision localization of hilar CC to provide surgeons with more information before the operation.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) can occasionally develop with other non-HCC cell types, either in a combined type or collision type. A collision tumor is defined as two histopathologically distinct tumors of the same organ lacking a clear transition zone. Hepatic collision tumors are rare. Among them, “hepatocellular carcinoma-hepatic neuroendocrine carcinoma” (HCC-NEC) collision tumors are especially rare and information about them is rarely published.
CASE SUMMARY A 48-year-old man with typical findings of HCC underwent consecutive therapies, including radiofrequency ablation and embolization prior to resection. Diagnosis of the HCC-NEC collision tumor in the right liver and another HCC in the left liver was established following surgical resection. The patient displayed NEC metastasis following resection and succumbed to septicemia after 2 more rounds of chemotherapy. To our knowledge, this is the 25th reported case of mixed HCC-NEC tumor. The rarity of HCC-NEC collision tumors and the absence of diagnostic criteria make it difficult to differentiate this condition from simple liver tumors, especially in patients with chronic liver disease.
CONCLUSION Our case highlights the difficulty in accurately diagnosing HCC-NEC in the absence of histological evidence. The prognosis is poor for this condition, although ultrasound-guided liver biopsy can be helpful to establish a prompt diagnosis. Further accumulation of such cases could help establish an accurate diagnosis earlier. Early discovery of NEC may allow for better treatment strategies and better prognoses.

Abstract
Esophageal neuroendocrine neoplasms (NEN) are extremely rare and little is known about their risk factors. To identify the potential risk factors, we evaluated whether the history of substance use, including alcohol, tobacco and areca nut consumption was associated with esophageal NEN. Forty-one esophageal NEN patients diagnosed between 2002 and 2019 from 17 hospital in Taiwan were enrolled as the cases. Controls were participants who received complete esophagogastroduodenoscopy in an endoscopic cohort and 123 eligible controls were matched to 41 cases (3:1) on age and gender. Alcohol drinking and cigarette smoking significantly increased the risk of esophageal NEN, with about a fourfold risk increase in alcohol drinkers as well as cigarette smokers. Moreover, use of cigarette smoking and alcohol consumption in combination demonstrated the highest risk of esophageal NEN with the risk increasing up to 20 times compared with non-users. Alcohol consumption and cigarette smoking significantly increase risk of esophageal NEN and both alcohol and cigarette users had the highest risk.

Abstract
BACKGROUND/PURPOSE Recurrent obscure gastrointestinal bleeding (OGIB) in patients with chronic kidney disease is a challenge often faced by physicians, given the need for repeated hospitalizations, multiple extensive examinations, limited treatment options, and high medical costs. The purpose of this study was to identify the clinical characteristics of uremic patients undergoing deep enteroscopy for OGIB and analyze the risk factors for rebleeding in these patients after undergoing single-balloon enteroscopy (SBE). METHODS Out of 765 patients with OGIB who underwent 1004 procedures of SBE in four teaching hospitals, 78 uremic patients with OGIB were enrolled. Clinical characteristics and endoscopic findings were collected, and multiple variables were analyzed to determine the risk of rebleeding after SBE. RESULTS The diagnostic yield was 75.6%, and the rebleeding rate was 29.5% in the enrolled uremic patients. The most common etiology was angiodysplasia (74.6%) and the most common site was the jejunum (50.8%). The endoscopic intervention rate was 62.8% and most patients were treated with argon plasma coagulation (75.6%). Among the eight patients with valvular heart disease (VHD), four (50%) had severe aortic stenosis, and the remaining had non-aortic stenosis-VHD. VHD (p < 0.05) and angiodysplasia (p < 0.05) were both associated with a higher rebleeding rate. CONCLUSION VHD may be an independent risk factor associated with rebleeding after SBE in uremic patients with OGIB. Moreover, uremic patients with angiodysplasia-related bleeding appear to have a higher rebleeding rate than those with alternative causes of bleeding.

Abstract
ABSTRACT Diagnosing pancreatic heterotopia (PH) is challenging, because it is a rare congenital anomaly. We report the case of a 66-year-old man who presented with ileus and jejunal PH diagnosed using single-balloon enteroscopy. Reviewing 178 cases of small intestinal PH in the literature showed that (1) PH mostly occurred at the duodenum (61.8%), followed by the jejunum (22.5%) and ileum (14.6%); (2) patients with ileal PH were younger (mean, 40.7 vs 54.6 years; P < 0.001), while those with jejunal PH were older (mean, 59.5 vs 51.7 years; P = 0.006); (3) most patients with jejunal PH were females, while those with duodenal or ileal PH were predominantly males (M:F = 0.8:1 vs 2.5:1; P = 0.003); (4) asymptomatic cases were rare (15.2% vs 83.4% in small and nonsmall bowel, respectively); (5) most patients with ileal PH presented with bleeding (61.5%), while the remaining had abdominal pain (42.8%); (6) emergent operation was performed in 11 cases (6.2%), mainly at the jejunum (12.5%) and Meckel's diverticulum (25%); and (7) Heinrich's classification may be inconclusive. Enteroscopy was performed in only 6 cases (3.4%), and earlier diagnosis and further minimally invasive procedures could have been achieved with enteroscopy.

Abstract
Malignancies of the head and neck (HN) region and esophagus are among the most common cancers worldwide. Due to exposure to common carcinogens and the theory of field cancerization, HN cancer patients have a high risk of developing second primary tumors (SPTs). In our review of 28 studies with 51,454 HN cancer patients, the prevalence of SPTs was 12%. The HN area is the most common site of SPTs, followed by the lungs and esophagus, and 13% of HN cancer patients have been reported to have esophageal high-grade dysplasia or invasive carcinoma. The prognosis of HN cancer patients with concomitant esophageal SPTs is poor, and therefore identifying esophageal SPTs as early as possible is of paramount importance for risk stratification and to guide the treatment strategy. Image-enhanced endoscopy, especially using narrow-band imaging endoscopy and Lugol’s chromoendoscopy, has been shown to improve the diagnostic performance in detecting esophageal neoplasms at an early stage. Moreover, the early detection and minimally invasive endoscopic treatment of early esophageal neoplasm has been shown to improve the prognosis. Well-designed prospective studies are warranted to establish appropriate treatment and surveillance programs for HN cancer patients with esophageal SPTs.

Abstract
The COVID-19 pandemic stressed healthcare systems all over the world. Two primary challenges that healthcare systems faced were a shortage of personal protective equipment and the need for new technologies to handle infection prevention for staff and patients. The Department of Veteran's Affairs (VA) Technology Transfer Program responded by prioritizing the development of innovations in the Technology Transfer Assistance Project which addressed the pandemic. This paper describes several innovations that addressed the needs of the VA healthcare system during the pandemic and how they were rapidly developed.

Abstract
Simple Summary Detection of early esophageal cancer is important to improve patient survival, however, early diagnosis of the cancer cells is difficult, even for experienced endoscopists. This article provides a new method by using hyperspectral imaging and a deep learning diagnosis model to classify and diagnose esophageal cancer using a single-shot multibox detector. The accuracy of the results when using an RGB image in WLI was 83% and while using the spectrum data the accuracy was increased to 88%. There was an increase of 5% in WLI. The accuracy of the results when using an RGB image in NBI was 86% and while using the spectrum data the accuracy was increased to 91%. There was an increase of 5% in NBI. This study proves that the accuracy of prediction when using the spectrum data has been significantly improved and the diagnosis of narrow-band endoscopy data is more sensitive than that of white-light endoscopy. Abstract This study uses hyperspectral imaging (HSI) and a deep learning diagnosis model that can identify the stage of esophageal cancer and mark the locations. This model simulates the spectrum data from the image using an algorithm developed in this study which is combined with deep learning for the classification and diagnosis of esophageal cancer using a single-shot multibox detector (SSD)-based identification system. Some 155 white-light endoscopic images and 153 narrow-band endoscopic images of esophageal cancer were used to evaluate the prediction model. The algorithm took 19 s to predict the results of 308 test images and the accuracy of the test results of the WLI and NBI esophageal cancer was 88 and 91%, respectively, when using the spectral data. Compared with RGB images, the accuracy of the WLI was 83% and the NBI was 86%. In this study, the accuracy of the WLI and NBI was increased by 5%, confirming that the prediction accuracy of the HSI detection method is significantly improved.

Abstract
BACKGROUND AND AIMS Intrapapillary capillary loops (IPCLs) are microvascular structures that correlate with the invasion depth of early squamous cell neoplasia and allow accurate prediction of histology. Artificial intelligence may improve human recognition of IPCL patterns and prediction of histology to allow prompt access to endoscopic therapy for early squamous cell neoplasia where appropriate. METHODS One hundred fifteen patients were recruited at 2 academic Taiwanese hospitals. Magnification endoscopy narrow-band imaging videos of squamous mucosa were labeled as dysplastic or normal according to their histology, and IPCL patterns were classified by consensus of 3 experienced clinicians. A convolutional neural network (CNN) was trained to classify IPCLs, using 67,742 high-quality magnification endoscopy narrow-band images by 5-fold cross validation. Performance measures were calculated to give an average F1 score, accuracy, sensitivity, and specificity. A panel of 5 Asian and 4 European experts predicted the histology of a random selection of 158 images using the Japanese Endoscopic Society IPCL classification; accuracy, sensitivity, specificity, positive and negative predictive values were calculated. RESULTS Expert European Union (EU) and Asian endoscopists attained F1 scores (a measure of binary classification accuracy) of 97.0% and 98%, respectively. Sensitivity and accuracy of the EU and Asian clinicians were 97%, 98% and 96.9%, 97.1%, respectively. The CNN average F1 score was 94%, sensitivity 93.7%, and accuracy 91.7%. Our CNN operates at video rate and generates class activation maps that can be used to visually validate CNN predictions. CONCLUSIONS We report a clinically interpretable CNN developed to predict histology based on IPCL patterns, in real time, using the largest reported dataset of images for this purpose. Our CNN achieved diagnostic performance comparable with an expert panel of endoscopists.

Abstract
BACKGROUND Graft rejection after intestinal transplantation remains challenging. We aimed to use endoscopy for rejection prediction. MATERIALS AND METHODS Patients ≥7 years old who underwent intestinal transplantation between November 2016 and September 2019 were prospectively enrolled. Magnifying endoscopy under narrow-band imaging was performed through ileostomy. Endoscopic findings were reported as five components (each graded from 0-2): "V" (villi appearance), "E" (erythema), "N" (capillary network), "C" (crypt widening), and "H" (heterogeneity). The correlation between histological severity and endoscopic score was analyzed. RESULTS Ninety-nine endoscopic biopsies from three female and one male patient were analyzed. The mean ± SD age was of 41.25±13.77 (range 29-58) years. Three short bowel syndrome patients after multiple intestinal resections and one with chronic intestinal pseudo-obstruction were indicated for intestinal transplantation. Sensitivity, specificity, and accuracy of V, E, N, C, and H scores for predicting rejection were 97.4%, 45.9%, 65.7%; 94.7%, 70.5%, 79.8%; 97.4%, 52.5%, 69.7%; 94.7%, 54.1%, 69.7%; and 97.4%, 62.3%, 75.8%, respectively. Pearson's correlation coefficients between total and individual V, E, N, C, H scores and histological rejection were 0.79, 0.64, 0.70, 0.71, 0.73, and 0.66, respectively (P < .001). To predict mild and moderate/severe rejection, total scores more than 4 and 6 had the sensitivity/specificity of 87.50%/57.38% and 96.67%/85.25%, respectively (area under the ROC 0.791 and 0.987). CONCLUSION Endoscopic VENCH scoring is promising for predicting rejection after IT. More studies are warranted to validate such results. (ClinicalTrials.gov number, NCT03616548.).

Abstract
BACKGROUND Third space endoscopy technique facilitates therapeutic endoscopy in subepithelial space. This study aimed to investigate peroral endoscopic tumor resection (POET) with preserved mucosa technique for upper gastrointestinal tract subepithelial tumors (UGI-SETs) removal. METHODS Between February 2011 and December 2019, consecutive patients with SETs of esophagus and stomach who underwent POET for enlarging size during follow-up, malignant endoscopic ultrasound features or by patient's request were enrolled. Demographic, endoscopic and pathological data were analyzed retrospectively. RESULTS Totally 18 esophageal (mean ± SD age, 55.23 ± 4.15 year-old, 38.89% female) and 30 gastric (52.65 ± 2.43 year-old, 53.33% female) SETs in 47 patients (one with both esophageal and gastric lesions) were resected. The mean (± SD) endoscopic/pathological tumor size, procedure time, en-bloc/complete resection rate, and hospital stays of esophageal and gastric SET patients were 12.36 (± 7.89)/11.86 (± 5.67) and 12.57 (± 6.25)/12.35 (± 5.73) mm, 14.86 (± 6.15) and 38.21 (± 15.29) minutes, 88.89%/94.44% and 86.77%/93.30%, and 4.14 (± 0.21) and 4.17 (± 0.20) days, respectively. The overall complication rate was 18.75%, including 6 self-limited fever and 3 pneumoperitoneum relieved by needle puncture. There was no mortality or recurrence reported with mean follow-up period of 23.74 (± 4.12) months. CONCLUSIONS POET is a safe and efficient third space endoscopic resection technique for removal of UGI-SETs less than 20 mm. Long term data are warranted to validate these results.

Abstract
BACKGROUND & AIMS Esophageal neuroendocrine tumors (NET) are very rare and mostly carcinomic, carrying poor prognosis. There is still no guideline or consensus on the treatment for esophageal NET. METHODS Patients with histologically-proven esophageal neuroendocrine tumor were recruited from 9 hospitals in Taiwan between 2002 and 2017. Clinical, laboratory, radiological, endoscopic, pathological data, treatment strategies, follow-up periods, and survivals were collected retrospectively. RESULTS In total, 39 esophageal NET were analyzed and 38 were neuroendocrine carcinoma (NEC). Sixteen (41%) patients had mixed components with either adenocarcinoma (N = 9, 23%) or squamous-cell carcinoma (SCC) (N = 7, 18%). 64.1% of the patients experienced dysphagia and ulcerative mass was the most comment endoscopic finding. There was a higher proportion of drinkers (54.1%), betel chewers (21.6%) and smokers (64.9%) among the patients than in the general population in Taiwan. Five patients (12.8%) had been diagnosed with other cancers. Definite chemoradiotherapy (N = 14, 35.9%) and surgery (N = 7, 17.9%) were the major treatment. Patients with Ki-67% above the median level (50%) in the tumors tended to have worse survival (P = 0.06). However, presence of mixed component was not a significant survival predictor in our study (P = 0.56). CONCLUSION Mixed component of an esophageal NET is commonly observed. Staged workup and the principle of treatment can follow that for the common cancer type of esophagus. The risk factors and behaviors of esophageal NEC in Taiwan seem to be similar to that of esophageal SCC.

Abstract
BACKGROUND/PURPOSE Inflammatory bowel disease (IBD) is a chronic gastrointestinal (GI) disorder that causes relapsing inflammation and severe mucosal damage in the intestine. Crohn's disease (CD)-related stricturing complications are a major cause of surgery, disability, and reduced quality of life. Endoscopic balloon dilation (EBD) has been shown to reliably delay or prevent surgery in patients with stricturing CD. However, cases of EBD performed for stricture in CD in Taiwan are rare. In this study, we want to evaluate the experiences regarding EBD for stricturing CD in Taiwan. METHODS We conducted a retrospective analysis of 9 medical centers in Taiwan. Patients with CD-related strictures who were treated with EBD were included and analyzed. RESULTS In nine medical centers, a total of 26 CD patients (19 male, 7 female, mean disease duration 75.4 ± 65.2 months) underwent 42 EBD procedures during the study period. Among the subjects, an 83.3% (35/42) EBD success rate was seen, but 26.9% (7/26) patients underwent surgery after ineffective EBD. In the surgery group, the the small bowel strictures was high compared with the non-surgery group (p = 0.01). There were no significant differences in disease phenotype, disease duration or history of fistulizing disease. In the surgery group, immunosuppressant use was high, and 5-aminosalicylic acid (5-ASA) use was low compared with the non-surgery group. After EBD, the physicians tended to change the drugs, especially increasing the use of biologic agents. CONCLUSION EBD is a safe and effective procedure for CD-related stricture, with a 83.3% success rate in Taiwan.

Abstract
Bowel microbiota is a "metaorgan" of metabolisms on which quantitative readouts must be performed before interventions can be introduced and evaluated. The study of the effects of probiotic Clostridium butyricum MIYAIRI 588 (CBM588) on intestine transplantees indicated an increased percentage of the "other glycan degradation" pathway in 16S-rRNA-inferred metagenomes. To verify the prediction, a scoring system of carbohydrate metabolisms derived from shotgun metagenomes was developed using hidden Markov models. A significant correlation (R = 0.9, p < 0.015) between both modalities was demonstrated. An independent validation revealed a strong complementarity (R = -0.97, p < 0.002) between the scores and the abundance of "glycogen degradation" in bacteria communities. On applying the system to bacteria genomes, CBM588 had only 1 match and ranked higher than the other 8 bacteria evaluated. The gram-stain properties were significantly correlated to the scores (p < 5 × 10-4). The distributions of the scored protein domains indicated that CBM588 had a considerably higher (p < 10-5) proportion of carbohydrate-binding modules than other bacteria, which suggested the superior ability of CBM588 to access carbohydrates as a metabolic driver to the bowel microbiome. These results demonstrated the use of integrated counts of protein domains as a feasible readout for metabolic potential within bacteria genomes and human metagenomes.

Abstract
Gastric neuroendocrine tumors (GNETs) are a heterogeneous group of neoplasm with varying biological characteristics. This study aimed to investigate the clinical features and outcomes of GNET patients after endoscopic diagnosis and treatment in a multicenter registry. Patients with GNETs confirmed histologically were recruited from 17 hospitals between January 2010 and April 2016 in Taiwan. Clinical, laboratory, radiological, endoscopic, pathological data, treatment strategies, follow-up periods, and survivals were collected retrospectively. Totally 187 (107 female, 80 male) patients were recruited. Mean ( ± standard deviation [SD]) age and size of tumors were 63.2-year-old ( ± 14.6) and 2.3-cm ( ± 3.0). World Health Organization (WHO) grading were 93 (49.7%) G1, 26 (13.9%) G2, 40 (21.4%) G3, and 28 (15.0%) unknown. G3 patients were older (mean ± SD, 71.6 ± 12.4 vs. 60.9 ± 14.3/56.7 ± 15.4 years), larger (6.1 ± 4.0 vs.1.2 ± 1.3/2.4 ± 2.5 cm), more distally located (35.0% vs. 7.6%/15.4%), lower proportion of superficial lesions (17.5% vs. 61.9%/53.8%) and higher rates of lymphovascular invasion (32.5% vs. 3.2%/7.7%) than G1/G2. There was no nodal or distant organ metastases despite different grading of lesions≦10 mm and those <20 mm limited to mucosa and submucosa layers. GNETs larger than 20 mm with G1, G2, and G3 had lymph node (LN) metastatic rates of 21.4%, 30.0%, and 59.3%, respectively. Survivals were different between grading for those >20 mm (log-rank test P = .02). Male gender (P = .01), deeper invasion (P = .0001), nodal (P < .0001), and distant organ metastases (P = .0001) were associated with worse outcome. In conclusion, treatment strategies for GNET should be decided by grading, size, invasiveness, and LN metastasis risk. Curative endoscopic resection is feasible for G1/2 lesions less than 20 mm and limited to mucosa/submucosa layers without lymphovascular invasion.

Abstract
BACKGROUND AND AIMS The incidence and disease burden of colorectal cancer (CRC) in young adults were increasing. However, there was a dearth of advice on how to identify young population at risk for neoplastic colonic polyps (NCPs) and CRC. We aimed to identify risk factors for NCPs and CRC in young adults presenting with bloody stool. METHODS A total of 1496 subjects younger than 40 years old who underwent colonoscopy due to bloody stool from 2005 to 2014 were enrolled in this retrospective study as the study group, and 1481 age-matched and gender-matched asymptomatic subjects who underwent colonoscopy for health checkup from 2011 to 2016 were enrolled as the control group at a tertiary center hospital. RESULTS Multivariate analysis results showed that increasing age (odds ratio [OR] = 1.11, 95% confidence interval [CI]: 1.07-1.15, P < 0.001), higher body mass index (BMI) (OR = 1.07, 95%CI: 1.03-1.12, P = 0.001), diabetes mellitus (OR = 2.80, 95%CI: 1.06-7.42, P = 0.038), and positive family history of CRC (OR = 13.28, 95%CI: 5.70-30.97, P < 0.001) were identified as independent risk factors for NCPs in study group. The best cut-off values by receiver operating characteristic curve for age and BMI were 32 years old and 24.8 kg/m2 , respectively. More risk factors were associated with the higher risk for NCPs (OR = 2.17 every increasing one risk factor, P < 0.001). In the control group, no independent risk factors were identified. CONCLUSIONS Adults aged ≤ 40 years with bloody stool who had increasing age (> 32 years old), higher BMI (> 24.8 kg/m2 ), diabetes mellitus, and positive family history of CRC had a higher detection rate of NCPs and CRC.

Abstract
BACKGROUND AND AIM Optimal staging of the invasion depth of superficial esophageal squamous cell carcinoma is vital before endoscopic treatment. A new simplified magnified narrow-band imaging (M-NBI) classification system based on vascular architecture has recently been developed by the Japan Esophageal Society; however, its validity remains uncertain. METHODS A total of 11 experienced and 11 inexperienced endoscopists were invited to join an endoscopic training program, which was composed of pretest, educational section, and post-test. The pretest and post-test sections included a set of endoscopic photos from 40 subjects with superficial esophageal squamous cell carcinoma with various invasion depths. Each subject appeared twice in the test, one with white-light imaging (WLI) only and the other with both WLI and M-NBI. The educational section included lectures and video demonstrations. RESULTS The accuracy of WLI alone and combined with M-NBI at baseline were 0.53, 0.57 and 0.43, 0.41 for the experienced and inexperienced endoscopists, respectively, which then improved to 0.57, 0.63 and 0.49, 0.52 after training. Inter-observer agreement (k-value) of WLI alone and combined WLI and M-NBI for the experienced and inexperienced endoscopists also improved from 0.61, 0.61, and 0.61, 0.53 to 0.68, 0.71, and 0.71, 0.59, respectively. Multivariate analysis revealed that the educational course but not experience in endoscopy, NBI, or magnification significantly improved the diagnostic accuracy. M-NBI had a significant additional benefit to WLI, with an improvement in accuracy from 36% to 56% for the cases with m3/sm1 cancers (P < 0.05). CONCLUSIONS A well-designed training program can improve the diagnostic accuracy in evaluating cancer invasion depth, with substantial agreement.

Lu YF, Chung CS, Liu CY, Shueng PW, Wu LJ, Hsu CX, Kuo DY, Hou PY, Chou HL, Leong KI, How CH, Chou SF, Wang LY, Hsieh CH. Esophageal Metal Stents with Concurrent Chemoradiation Therapy for Locally Advanced Esophageal Cancer: Safe or Not? Oncologist 2018; 23:1426-1435. [PMID: 29728468 DOI: 10.1634/theoncologist.2017-0646] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [What about the content of this article?

Abstract
BACKGROUND The purpose of this study was to review the risks and benefits of concurrent chemoradiation therapy (CCRT) with esophageal self-expandable metal stents (SEMS) for the treatment of locally advanced esophageal cancer. MATERIALS AND METHODS Between January 2014 and December 2016, the data from 46 locally advanced esophageal cancer patients who received CCRT at our institution were retrospectively reviewed. Eight patients who received CCRT concomitant with SEMS placement (SEMS plus CCRT group) and thirty-eight patients who received CCRT without SEMS placement (CCRT group) were identified. The risk of developing esophageal fistula and the overall survival of the two groups were analyzed. RESULTS The rate of esophageal fistula formation during or after CCRT was 87.5% in the SEMS plus CCRT group and 2.6% in the CCRT group. The median doses of radiotherapy in the SEMS plus CCRT group and the CCRT group were 47.5 Gy and 50 Gy, respectively. SEMS combined with CCRT was associated with a greater risk of esophageal fistula formation than CCRT alone (hazard ratio [HR], 72.30; 95% confidence interval [CI], 8.62-606.12; p < .001). The median overall survival times in the SEMS plus CCRT and CCRT groups were 6 months and 16 months, respectively. Overall survival was significantly worse in the SEMS plus CCRT group than in the CCRT group (HR, 5.72; 95% CI, 2.15-15.21; p < .001). CONCLUSION CCRT concomitant with SEMS for locally advanced esophageal cancer results in earlier life-threatening morbidity and a higher mortality rate than treatment with CCRT alone. Further prospective and randomized studies are warranted to confirm these observations. IMPLICATIONS FOR PRACTICE Patients treated with SEMS placement followed by CCRT had higher risk of esophageal fistula formation and inferior overall survival rate compared with patients treated with CCRT alone. SEMS placement should be performed cautiously in patients who are scheduled to receive CCRT with curative intent.

Abstract
A 28-year-old man presented with anemia symptoms and intermittent tarry stool passage for three days. No stigmata of hemorrhage were identified using esophagogastroduodenoscopy, ileocolonoscopy, and contrast-enhanced computed tomography. He then developed massive tarry stool passage with profound hypovolemic shock and hypoxic respiratory failure. Emergent angiography revealed active bleeder, probably from the jejunal branches of the superior mesenteric artery, but embolization was not performed due to possible subsequent extensive bowel ischemia. His airway was secured via endotracheal intubation with ventilator support, and emergent antegrade single-balloon enteroscopy was performed at 8 h after clinical overt bleeding occurrence; the procedure revealed a 2-cm pulsating subepithelial tumor with a protruding blood plug at the distal jejunum. Laparoscopic segmental resection of the jejunum with end-to-end anastomosis was performed after emergent endoscopic tattooing localization. Pathological examination revealed a vascular malformation in the submucosa with an organizing thrombus. He was uneventfully discharged 5 d later. This case report highlights the benefit of early deep enteroscopy for the treatment of small intestinal bleeding.

Abstract
Objective To evaluate how evidence-based our daily practice was. Design Retrospective study. Setting Emergency department of a public district hospital. Patients and Methods Between 1st August 2000 to 7th August 2000, 91 patients' records were chosen at random. A chief diagnosis was assigned for each patient. Corresponding treatments were reviewed by searching relevant randomised controlled trials (RCTs), systematic reviews and meta-analyses. Each patient had only one chief diagnosis but could have multiple interventions for that diagnosis. Results Out of 91 records, 14 were discarded. All of them had not been given any intervention and 11 required admission. For the remaining 77 records, there were 38 subjects in medical, paediatric, or gynaecological specialties and 39 in surgical or orthopaedic specialties. Intervention(s) given for each subject were then searched electronically through our hospital Knowledge Gateway and the results were expressed as either EBM-positive or EBM-negative. “EBM-positive” interventions denoted a support by RCTs. “EBM-negative” interventions denoted an absence of any supportive RCTs. Each patient might have EBM-positive and/or EBM-negative interventions together if that patient received more than one treatment. There were 52 patients (52/77 = 68%) who had one of their interventions being RCT-supported. The majority were patients with (1) antipyretic use of paracetamol in upper respiratory tract infection, or (2) control of pain by nonsteroidal anti-inflammatory drug, dologesic and paracetamol. There were 25 patients (25/77 = 32%) who did not receive any RCT-supported interventions. Concurrently 53 patients out of 77 (69%) received EBM-negative interventions. The majority were patients with (1) the use of antibiotics, antitussives and antihistamines in upper respiratory tract infection, (2) antispasmodics in gastroenteritis or patients with nonspecific abdominal pain, and (3) the use of analgesic balm in minor orthopaedic complaints. Conclusion Sixty-eight percent of patients had EBM-positive interventions. Thirty-two percent of patients did not receive any EBM-positive intervention. It was quite encouraging as compared to studies in other specialties with similar design. Concurrently 69% of patients had also been given EBM-negative interventions. There were areas for improvement if we were to implement EBM practice in the emergency department.

Abstract
BACKGROUND/PURPOSE Small bowel (SB) accounts for the majority of gastrointestinal tract but its tumors are rare and always overlooked. In this study, we aimed to evaluate the epidemiology of SB tumors. METHODS This multicenter retrospective study utilized endoscopy database from 2006/11 to 2016/07. Baseline demographic characteristics, clinical, radiologic and endoscopic findings were collected. RESULTS Totally 103 (34 benign, 69 malignant lesions) patients with SB tumors in 1070 enteroscopic examinations were enrolled. There were male preponderance (56.3% males, 43.7% females), both in benign (52.9%, 49.1%) and malignant (58.0%, 42.0%) lesions, except for subtype gastrointestinal stromal tumors (GISTs) (31.6%, 68.4%). The age (mean ± SD) at diagnosis in malignant SB tumors (62.2 ± 15.6) was older than those with benign tumors (50.7 ± 21.4) (p < 0.01). Bleeding (43.7%), abdominal pain (40.8%) and ileus (10.7%) were the most common clinical presentations. Hamartoma (32.4%) and adenoma (14.7%) were the most common benign histology. Four major malignant histological subtypes were lymphomas (29.0%), GISTs (27.5%), adenocarcinomas (26.1%) and metastatic cancers (14.5%). SB adenocarcinoma patients (>60-year-old, 77.8%) were older than lymphomas (60%) and GISTs (50%). Proximally location rates of lymphomas, GISTs, adenocarcinomas were 25.0% (5/20), 84.2% (16/19), and 88.9% (16/18), respectively. CONCLUSION This endoscopy-based study revealed the most common histology of benign SB tumors were hamartoma and adenoma, and malignant ones were lymphomas, GISTs, adenocarcinomas and metastatic cancers. Most of them were male gender, except for GISTs, and with proximal location, except for lymphomas. Further large-scale investigation efforts are warranted to elucidate the epidemiology of SB tumors.

Abstract
OBJECTIVE Several studies suggested that colonic microbiota have impacts on irritable bowel syndrome (IBS) patients. However, the knowledge about the association of small intestine (SI) microbiota with IBS is limited. We aimed to investigate the gut microbiota composition of SI and stool in IBS patients. MATERIALS AND METHODS Biopsies of jejunum mucosa by balloon-assisted enteroscopy and faecal samples from 28 IBS patients and 19 healthy controls were analysed by next-generation sequencing method. RESULTS The three major phyla in SI microbiota of case/control groups were Proteobacteria (32.8/47.7%), Bacteroidetes (25.2/15.3%), and Firmicutes (19.8/11.2%), and those of stool were Bacteroidetes (41.3/45.8%), Firmicutes (40.7/38.2%), and Proteobacteria (15.4/7.1%). Analysis based on the family level, IBS patients had a higher proportion of Veillonellaceae (mean proportion 6.49% versus 2.68%, p = 0.046) in stool than controls. Prevotellaceae was more abundant in IBS patients than in control group (14.27% versus 6.13%, p = 0.023), while Mycobacteriaceae (0.06% versus 0.17%, p = 0.024) and Neisseriaceae (6.40% versus 8.94%, p = 0.038) was less abundant in IBS patients' jejunal mucosa than those in controls. This less abundant jejunal Neisseriaceae was associated with more severe IBS (p = 0.03). The ratio of Firmicutes to Bacteroidetes in the stool of IBS-diarrhoea type patients was approximately three-fold higher, and the ratio of Firmicutes to Actinobacter in SI of IBS-mixed type patients was about nine-fold higher than healthy subjects. CONCLUSION Higher abundance of colonic Veillonellaceae and SI Prevotellaceae, and lower amount of oral cavity normal flora in proximal SI were found in IBS patients. We may manipulate these bacteria in IBS patients in future studies (ClinicalTrial.gov Number NCT01679730).

Abstract
Synchronous second primary tumors (SPTs), especially esophageal squamous cell neoplasia (ESCN), in patients with head and neck squamous cell carcinoma (HNSCC) are not uncommon. Image-enhanced endoscopy (IEE) screening may identify SPTs while there is no evidence to support its benefit. We prospectively recruited an adult cohort with newly-diagnosed HNSCC for IEE screening of upper gastrointestinal (UGI) tract neoplasia. 145 HNSCC patients were recruited. 22 (15.2%) patients had synchronous UGI tract neoplasia, including 20 ESCNs and 2 gastric adenocarcinoma. At a median follow-up of 2.72 (±1.73) years, the 3-year overall survival (OS) rate was 0.71. HNSCC patients with synchronous ESCN/UGI tract neoplasia had poorer prognosis than those without (multivariate analysis, hazard ratio [HR] 2.75/2.79, 95% confidence interval [CI] 1.11~6.82/1.15~6.80, p = 0.03/0.02). HNSCC patients with advanced (stage III&IV) ESCN had worst survivals (p < 0.001). Among those with synchronous ESCNs, hypopharyngeal cancers were associated with poorer prognosis when compared with oral cancers (HR 2.36, 95% CI 1.08~5.15, p = 0.03). IEE screening for UGI SPTs in HNSCC patients could be used for risk stratification and prognosis prediction. HNSCC patients with advanced ESCN had the worst prognosis. Further studies are needed to demonstrate the survival benefits from IEE screening.

Abstract
BACKGROUND Endoscopic radiofrequency ablation (RFA) is a rapidly evolving therapeutic modality for early flat esophageal squamous cell neoplasms (ESCNs), but the risk factors for postoperative stricture have not been elucidated. The objective of this study was to identify and validate a predictor for post-RFA stenosis. METHODS We consecutively enrolled patients with flat-type 'large' (length no less than 3 cm extending no less than half the circumference of the esophagus), early ESCNs, treated with balloon-based RFA (12 J/cm(2)-clean-12 J/cm(2) regimen). The tumor and technical factors for postoperative stricture were investigated and we validated the results externally with a society-based multicenter cohort using the same ablation regimen. RESULTS A total of 51 patients were enrolled (30 in the development set and 21 in the validation set). The complete remission rate at 12 months was 93%, and the rates of perforation and postoperative stenosis were 0% and 17%, respectively. Patients with post-RFA stenosis had a significantly larger longitudinal tumor size (mean 115 versus 61 mm, p = 0.003). There were no significant differences in age, body mass index, tumor circumferential extension, pretreatment histological grade, treatment efficacy or size of balloon catheter between the groups with or without stenosis. The optimal cut-off value was set as 9 cm to predict post-RFA stenosis by receiver operating characteristic curve [area under curve (AUC) = 0.881], which was then confirmed to be a reliable predictor by multivariate analysis (odds ratio, 12.7, 95% confidence interval, 1.18-136.28, p = 0.03) and have a good predictive performance in the validation set (AUC = 0.876). CONCLUSIONS The most frequent adverse event of RFA was esophageal stenosis, for which the longitudinal tumor size was a significant predictive factor. Early intervention or prevention for stricture should be applied for those with long segment (⩾9 cm) ESCNs.

Abstract
BACKGROUND/PURPOSE Although prophylactic antibiotics have been recommended for cirrhotic patients with upper gastrointestinal bleeding, the duration of its use remains an inconclusive issue. We designed this study to investigate the duration of antibiotic prophylaxis for cirrhotic patients with acute esophageal variceal bleeding. METHODS We enrolled those patients suffering from acute esophageal variceal bleeding and receiving band ligation. They were randomly allocated to two groups to receive prophylactic antibiotics; Group I: receiving intravenous ceftriaxone 500 mg every 12 hours for 3 days, and Group II: same regimen for 7 days. We used rebleeding rate within 14 days as the primary end point and also evaluated the survival rate within 28 days and the amount of transfusion during admission. RESULTS There were 38 patients in Group I and 33 patients in Group II that completed the study course for analysis. Overall, there was no significant difference in the baseline characteristics between these two groups. There were three patients both in Group I and Group II who developed rebleeding within 14 days (8% vs. 9%, p > 0.99). There was also no difference between Group I and Group II in transfusion amount (2.71 ± 2.84 units vs. 3.18 ± 4.07, p = 0.839) and survival rate in 28 days (100 vs. 97%, p = 0.465). CONCLUSION Our small scale study demonstrated that there was no difference in the rebleeding rate between 3-day and 7-day ceftriaxone prophylaxis for cirrhotic patients with acute esophageal variceal bleeding. There was also no difference in 28 day survival rate between these two groups.

Abstract
Esophageal cancer is the eighth most common cancer worldwide. Esophageal adenocarcinoma (EAC) and esophageal squamous cell carcinoma (ESCC) are the two major phenotypes in Western and Eastern countries, respectively. Because of different pathways in carcinogenesis, the risk factors and effective steps for prevention of esophageal cancer are different between EAC and ESCC. The carcinogenesis of EAC is initiated by the acid exposure of the esophageal mucosa from stomach while that of the ESCC are related to the chronic irritation of carcinogens mainly by the alcohol, cigarette, betel quid, and hot beverage. To eliminate the burden of esophageal cancer on the global health, the effective strategy should be composed of the primary, secondary, and tertiary prevention. In this article, we perform a systematic review of the preventive strategies for esophageal cancer with special emphasis on the differences from the perspectives of Western and Eastern countries.

Abstract
An idiopathic peptic ulcer is defined as an ulcer with unknown cause or an ulcer that appears to arise spontaneously. The first step in treatment is to exclude common possible causes, including Helicobacter pylori infection, infection with other pathogens, ulcerogenic drugs, and uncommon diseases with upper gastrointestinal manifestations. When all known causes are excluded, a diagnosis of idiopathic peptic ulcer can be made. A patient whose peptic ulcer is idiopathic may have a higher risk for complicated ulcer disease, a poorer response to gastric acid suppressants, and a higher recurrence rate after treatment. Risk factors associated with this disease may include genetic predisposition, older age, chronic mesenteric ischemia, smoking, concomitant diseases, a higher American Society of Anesthesiologists score, and higher stress. Therefore, the diagnosis and management of emerging disease should systematically explore all known causes and treat underlying disease, while including regular endoscopic surveillance to confirm ulcer healing and the use of proton-pump inhibitors on a case-by-case basis.

Abstract
Aortic pseudoaneurysm formation subsequent to concurrent chemoradiotherapy (CCRT) for esophageal cancer patient with esophageal metallic stent insertion is a rare condition.A 52-year-old man with esophageal cancer, cT4N1M0, stage IIIC, was treated with concurrent weekly cisplatin (30 mg/m) and 5-Fluorouracil (500 mg/m) as well as radiotherapy (50.4 Gy in 28 fractions) for 6 weeks. An esophageal metallic stent was inserted for dysphagia 1 week after initiation of CCRT. During the treatment regimen, the platelet count dropped to less than 200 × 10 /μL. One month after the completion of CCRT, chest CT revealed the presence of an aortic pseudoaneurysm as well as aortoesophageal fistulas. A thoracic aortic endografting was performed and the patient responded well to surgery. However, the patient died 2 months later due to a nosocomial infection.Multimodality treatment for esophageal cancer comprising cisplatin-based CCRT and esophageal metallic stent placement near a great vessel may increase the risk of pseudoaneurysm formation.

Abstract
BACKGROUND Previous studies demonstrated that the sensitivity of rapid urease test (RUT) for diagnosis of Helicobacter pylori infection decreased during peptic ulcer bleeding. AIM We designed this study and tried to find a better method to improve the detection rate of H. pylori infection at the same session of endoscopic diagnosis of peptic ulcer bleeding. METHODS We prospectively enrolled 116 patients with peptic ulcer bleeding. These patients received intravenous proton pump inhibitor and then received upper gastrointestinal endoscopy within 24 h after arrival. We took one piece of biopsy from gastric antrum (Group 1), four pieces from gastric antrum (Group 2), and one piece from the gastric body (Group 3) for three separate RUTs, respectively. (13)C-urease breath test was used as gold standard for diagnosis of H. pylori infection. RESULTS There were 74 patients (64 %) with positive (13)C-urease breath test. Among these 74 patients, 45 patients had positive RUT (sensitivity: 61 %) in Group 1; 55 patients had positive RUT (sensitivity: 74 %) in Group 2; 54 patients had positive RUT (sensitivity: 73 %) in Group 3. There were significant differences between Group 1 and Group 2 (p = 0.02) and between Group 1 and Group 3 (p = 0.022). CONCLUSIONS The sensitivity of RUT was 61 % during peptic ulcer bleeding. The sensitivity of RUT can be increased significantly by increased biopsy number from gastric antrum or biopsy from gastric body.

Abstract
Obscure gastrointestinal bleeding is an uncommonly encountered and difficult-to-treat clinical problem in gastroenterology, but advancements in endoscopic and radiologic imaging modalities allow for greater accuracy in diagnosing obscure gastrointestinal bleeding. Ectopic varices account for less than 5% of all variceal bleeding cases, and jejunal variceal bleeding due to extrahepatic portal hypertension is rare. We present a 47-year-old man suffering from obscure gastrointestinal bleeding. Computed tomography of the abdomen revealed multiple vascular tufts around the proximal jejunum but no evidence of cirrhosis, and a visible hypodense filling defect suggestive of thrombus was visible in the superior mesenteric vein. Enteroscopy revealed several serpiginous varices in the proximal jejunum. Serologic data disclosed protein C deficiency (33.6%). The patient was successfully treated by therapeutic balloon-assisted enteroscopy and long-term anticoagulant therapy, which is normally contraindicated in patients with gastrointestinal bleeding. Diagnostic modalities for obscure gastrointestinal bleeding, such as capsule endoscopy, computed tomography enterography, magnetic resonance enterography, and enteroscopy, were also reviewed in this article.
