Abstract
BACKGROUND /aims: Placement of a self-expandable metal stent (SEMS) across the duodenal major papilla carries a risk of duodenobiliary reflux (DBR). The supra-papilla method of stenting may reduce DBR and improve stent patency compared to the trans-papilla method. This study aimed to compare the clinical outcomes between the supra-papilla and trans-papilla methods for distal malignant biliary obstruction (DMBO). METHODS Between January 2021 and January 2023, consecutive patients with DMBO from six centers in Korea were randomly assigned to either the supra-papilla or trans-papilla method arm in a 1:1 ratio. The primary outcome was the duration of stent patency, and secondary outcomes included the cause of stent dysfunction, adverse events, and overall survival rate. RESULTS A total of 84 patients were equally assigned to each group. The most common cause of DMBO was pancreatic cancer (n=50, 59.5%), followed by bile duct (n=20, 23.8%), gallbladder (n=11, 13.1%), and other cancers (n=3, 3.6%). Stent patency was significantly longer in the supra-papilla group (median [95% confidence interval], 369 [289-497] vs. 154 [78-361] days; P < 0.01). Development of DBR was significantly lower in the supra-papilla group (9.4% vs 40.8%, P < 0.01). Adverse events and overall survival rate were not significantly different between the two groups. CONCLUSIONS The placement of SEMS using the supra-papilla method resulted in a significantly longer duration of stent patency. It is advisable to place the SEMS using the supra-papilla method in DMBO. Further studies with a larger number of patients are required to validate the benefits of the supra-papilla method.

Abstract
BACKGROUND/AIM Distinguishing gastrointestinal involvement in classic follicular lymphoma (CFL) and duodenal-type follicular lymphoma (DFL) is crucial for proper treatment. This study aimed to describe an integrated diagnostic re-classification of gastrointestinal follicular lymphoma (GIFL) and identify useful features for its differential diagnosis. PATIENTS AND METHODS We reviewed radiological and endoscopic images and pathology slides of 22 GIFL cases, not otherwise specified. RESULTS Thirteen cases of duodenal grade 1 FL without nodal disease were re-classified as DFL. Five cases of non-duodenal grade 3 FL accompanied by nodal enlargement were re-classified as CFL. The DFL showed peripherally accentuated CD21 immunoreactivity, whereas the CFL showed strong homogeneous CD21 expression. Four atypical cases were re-classified as DFL and CFL in one and three cases, respectively. CONCLUSION Our findings support the notion that DFL differs from CFL. In cases of GIFL with atypical features, the possibility of gastrointestinal involvement by CFL should be considered. CD21 expression patterns can assist in the differential diagnosis of CFL and DFL.

Abstract
BACKGROUND AND AIMS This study aimed to evaluate whether the use of antiplatelet agents increases the risk of bleeding after gastric endoscopic submucosal dissection (ESD) and to determine the appropriate time to discontinue antiplatelet agents to minimize complications. METHODS This retrospective observational study utilized a collected dataset of patients who underwent ESD for gastric adenoma and cancer between January 2010 and December 2020. Patients were classified into three groups according to antiplatelet agent use and discontinuation status. We investigated the risk of post-ESD bleeding with different interruption times and antiplatelet agent types. RESULTS Of 1879 patients, 1389 were non-users, 190 were in the continuous group, and 203 were in the interrupted group. The rates of overall and delayed bleeding were significantly higher in patients who continued or were interrupted within three days before ESD than in the non-users and interrupted group (6.3% vs. 1.2%, p < 0.001, 6.3% vs. 2.5%, p = 0.01, respectively). Significant differences in delayed bleeding between the continuous and interrupted groups decreased with longer cessation periods. In multivariate analysis, continuous antiplatelet agents were still the strongest risk factor for bleeding (OR 2.81, 95% CI 1.14-6.90). Lower third location and longer procedure times were also independent risk factors for post-ESD bleeding (OR 2.75; 95% CI 1.08-6.97; OR 1.02; 95% CI 1.01-1.02). CONCLUSION Continuous antiplatelet agent use increases the risk of delayed bleeding after gastric ESD. Therefore, the optimal timing of interruption, rather than the type of antiplatelet agent, should be considered to avoid an additional risk of bleeding and thromboembolism.

Abstract
RATIONALE Sessile serrated lesions (SSLs) are serrated polyps (SP) with the typical serrated architecture of the crypt lining epithelium. SSL has an important clinical implication because they are recognized as precursor lesion of sporadic colorectal cancer (CRC) through "serrated pathway." SSLs usually appear flat to sessile, and are located in the right colon. PATIENT CONCERNS A 69-year-old man was referred to a tertiary medical center because of intermittent hematochezia for 2 years. DIAGNOSIS Colonoscopy revealed a large, pedunculated polyp in the rectum. The polyp surface was slightly reddish in color and the elongated stalk was covered with almost normal mucosa. Histopathological examination of the resected specimens revealed the typical features of SSL with low-grade dysplasia. INTERVENTION Endoscopic mucosal resection using a detachable snare was performed on the tumor for definite diagnosis and treatment. OUTCOMES There was no evidence of immediate or delayed bleeding after endoscopic mucosal resection, and the hemoglobin level normalized after a 1-year follow-up. LESSONS We report a rare case of a large pedunculated polyp with typical histological features of SSLs in the rectum. Endoscopists should always consider SSLs at any location even with unusual morphological findings.

Abstract
Fluoroscopy is used frequently during endoscopic procedures, such as endoscopic retrograde cholangiopancreatography (ERCP). However, exposure to radiation is an important health concern, primarily because of the potential increase in the lifetime risk of malignancy. This consideration is important for patients and staff exposed to radiation during ERCP. Thus, an understanding of how radiation doses are measured during ERCP and the potential risks of this radiation is important. Additionally, staff must be educated about methods used to minimize the radiation dose, such as the use of different imaging techniques, the general principles of fluoroscopy, and advances in hardware and software. The use of personal protective equipment is also essential to minimize occupational exposure. However, no comprehensive ERCP guideline on the use of X-ray systems in clinical settings or on radiation protection for operators has been established. This review focuses on the properties of fluoroscopy systems and methods of radiation protection for physicians and assistants participating in ERCP.

Abstract
Although lactose-free dairy products for the clinical management of lactose intolerance (LI) are widely available, scientific evidence on their efficacy is still lacking. This study comparatively analyzed the efficacy of flavored lactose-free milk (LFM) and whole milk (WM) in reducing symptoms in South Korean adults with LI. This prospective study was conducted in adults suspected of LI. All screened participants underwent the hydrogen breath test (HBT) using 570 mL of chocolate-flavored WM (20 g of lactose) and responded to a symptom questionnaire. LI was confirmed when the ΔH2 peak exceeded 16 ppm above baseline values and with the occurrence of symptoms after WM consumption. The participants who were diagnosed with LI underwent the HBT again with 570 mL of chocolate-flavored LFM (0 g of lactose), followed by the symptom questionnaire survey after 1 week. After excluding 40 participants who did not meet the diagnostic criteria for LI and 2 who were lost to follow-up, a total of 28 lactose-intolerant individuals were enrolled in the study. The ΔH2 values in the first HBT were significantly higher than those in the second HBT (33.3 ± 21.6 ppm vs. 8.6 ± 6.3 ppm, P < .001). Similarly, there was a significant reduction in the total symptom score in the second HBT (4.18 ± 1.51 vs. 0.61 ± 0.98, P < .001). Flavored LFM is well tolerated in South Korean adults diagnosed with LI based on the HBT and symptom questionnaire results. Therefore, LFM may be a viable alternative to WM.

Abstract
BACKGROUND AND AIMS Little is known about the association between non-alcoholic fatty liver disease (NAFLD) and dementia. Given that hepatic steatosis is linked to abnormal fat metabolism, and fat dysregulation in the brain is related to dementia, we aimed to investigate whether NAFLD is associated with an increased risk of dementia. METHODS We conducted a nationwide cohort study involving 4 031 948 subjects aged 40-69 years who underwent ≥2 health check-ups provided by the National Health Insurance Service in Korea between January 2004 and December 2007. Based on the hepatic steatosis index (HSI), subjects were categorized into non-NAFLD (HSI <30 at all check-ups) and NAFLD (HSI >36 at one or more check-ups). Dementia defined by ICD-10 codes with prescription data was followed up until December 2017. Cox proportional hazards regression models analysed the dementia risk. RESULTS At baseline, 31.3% had NAFLD. During the median follow-up of 9.5 years, 138 424 in NAFLD group and 69 982 in non-NAFLD group developed dementia. NAFLD group was associated with a higher risk of dementia than non-NAFLD group on multivariable-adjusted analysis (hazard ratio [HR], 1.05; p < .001), competing risk analysis (HR, 1.08; p < .001) and propensity-score matched analysis (HR, 1.09; p < .001). The association between NAFLD and dementia risk was more prominent among females (HR, 1.16; p < .001). The association was stronger among non-obese NAFLD subjects (BMI <25 kg/m2 , HR, 1.09; p < .001) than obese NAFLD subjects. CONCLUSIONS This nationwide study found that NAFLD is associated with an increased risk of dementia. The association was prominent among females and non-obese NAFLD subjects.

Abstract
BACKGROUND The eradication rate of clarithromycin-based standard triple therapy (STT) for Helicobacter pylori infection has decreased due to clarithromycin resistance (CR). We evaluated the cost-effectiveness of tailored therapy according to CR test results, and compared the results of STT with those of empirical bismuth quadruple therapy (BQT). METHODS The prospectively collected data of 490 H. pylori-positive patients with chronic gastritis or peptic ulcer disease were retrospectively analyzed. Among them, 292 patients underwent CR testing using dual-priming oligonucleotide-based polymerase chain reaction. The tailored group (n = 292) consisted of patients treated with STT for 7 days and BQT for 10 days as per their CR test results. The remaining patients were assigned to the empirical group (n = 198) and received BQT for 10 days without a CR test. The eradication rate, adverse events and medical costs associated with H. pylori eradication therapy were investigated. RESULTS In the tested patients (tailored group), the CR-positive rate was 32.2% (n = 94/292). The eradication rate according to an intention-to-treat analysis was 87.7% in the tailored group and 91.8% in the empirical group (P = 0.124); the respective rates were 94.4% and 97.9% by per-protocol analysis (P = 0.010). The frequency of adverse events was lower in the empirical group than the tailored group (35.1% vs. 52.7%, P < 0.001). Total per capita medical costs were $406.50 and $503.50, respectively. CONCLUSIONS Ten-day empirical BQT was more effective, safer, and less expensive than tailored therapy based on a CR test for H. pylori eradication.

Here, we report an unusual manifestation of infiltrative duodenal cancer arising from a choledochocele, involving superficial spreading (muscularis mucosae) of cancer cells along the duodenum causing gastric outlet obstruction, which clinically mimicked superior mesenteric artery syndrome. Histologically, wide spread of cancer cells was confirmed from periampullary region to duodenojejunal junction showing mismatch with radiologic findings, in which the cancer segment was mainly located in the distal duodenum. Clinical, radiologic, and pathologic findings are discussed with literature reviews.

Abstract
BACKGROUND AND STUDY AIMS No standard ultrasonography (US) method exists for visualizing the distal common bile duct (CBD). The supine HD view is usually adopted for CBD evaluation, but duodenal or colonic gas shadowing can affect this view. PATIENTS AND METHODS We developed and evaluated an easy-to-perform technique, the supine distal CBD view, applying the US protocol for the distal CBD evaluation. Five reviewers checked the visibility of the distal CBD and cystic duct, as well as each view's image quality and influencing factors. RESULTS The visibility of the distal CBD was enhanced on the supine distal CBD view (86.0%-94.6%) versus the supine hepatoduodenal view (40.8%-82.1%), with less variability among the reviewers. The image quality of the supine distal CBD view was superior to that of the supine HD view (2.52 ± 0.67 vs. 1.93 ± 0.86, respectively; p < 0.01). The depth of the distal CBD from the surface was significantly larger in the patients with nonvisible distal CBDs. CONCLUSION We present a user-friendly, easy-to-perform US view for locating and visualizing the distal CBD. With this technique, the distal CBD can be evaluated without changing a patient's position or increasing the duration of the procedure.

Abstract
Crohn's disease (CD) is a chronic destructive inflammatory bowel disease that affects young people and is associated with significant morbidity. The clinical spectrum and disease course of CD are heterogeneous and often difficult to predict based on the initial presentation. In this article, changes in the disease location, behavior, clinical course during long-term follow-up, and predictive factors are reviewed. Generally, four different patterns of clinical course are discussed: remission, stable disease, chronic relapsing disease, and chronic refractory disease. Understanding the long-term disease course of CD is mandatory to reveal the underlying pathophysiology of the disease and to move toward a more optimistic disease course, such as remission or stability, and less adverse outcomes or devastating sequelae.

Abstract
Endoscopic ultrasound (EUS)-guided tissue acquisition of pancreatic solid tumor requires a strict recommendation for its proper use in clinical practice because of its technical difficulty and invasiveness. The Korean Society of Gastrointestinal Endoscopy appointed a Task Force to draft clinical practice guidelines for EUS-guided tissue acquisition of pancreatic solid tumor. The strength of recommendation and the level of evidence for each statement were graded according to the Minds Handbook for Clinical Practice Guideline Development 2014. The committee, comprising a development panel of 16 endosonographers and an expert on guideline development methodology, developed 12 evidence-based recommendations in eight categories intended to help physicians make evidence- based clinical judgments with regard to the diagnosis of pancreatic solid tumor. This clinical practice guideline discusses EUS-guided sampling in pancreatic solid tumor and makes recommendations on circumstances that warrant its use, technical issues related to maximizing the diagnostic yield (e.g., needle type, needle diameter, adequate number of needle passes, sample obtaining techniques, and methods of specimen processing), adverse events of EUS-guided tissue acquisition, and learning-related issues. This guideline was reviewed by external experts and suggests best practices recommended based on the evidence available at the time of preparation. This guideline may not be applicable for all clinical situations and should be interpreted in light of specific situations and the availability of resources. It will be revised as necessary to cover progress and changes in technology and evidence from clinical practice.

Abstract
Endoscopic ultrasonography-guided intervention has gradually become a standard treatment for peripancreatic fluid collections (PFCs). However, it is difficult to popularize the procedure in Korea because of restrictions on insurance claims regarding the use of endoscopic accessories, as well as the lack of standardized Korean clinical practice guidelines. The Korean Society of Gastrointestinal Endoscopy (KSGE) appointed a Task Force to develope medical guidelines by referring to the manual for clinical practice guidelines development prepared by the National Evidence-Based Healthcare Collaborating Agency. Previous studies on PFCs were searched, and certain studies were selected with the help of experts. Then, a set of key questions was selected, and treatment guidelines were systematically reviewed. Answers to these questions and recommendations were selected via peer review. This guideline discusses endoscopic management of PFCs and makes recommendations on Indications for the procedure, pre-procedural preparations, optimal approach for drainage, procedural considerations (e.g., types of stent, advantages and disadvantages of plastic and metal stents, and accessories), adverse events of endoscopic intervention, and procedural quality issues. This guideline was reviewed by external experts and suggests best practices recommended based on the evidence available at the time of preparation. This will be revised as necessary to address advances and changes in technology and evidence obtained in clinical practice and future studies.

Abstract
Background Cerebral microbleeds (CMBs) are small, rounded, dark-signal lesions on brain MRI that represent cerebral hemosiderin deposits resulting from prior microhemorrhages and are neuroimaging biomarkers of cerebral amyloid angiopathy (CAA). Here, we report a case of innumerable CMBs in a patient with hepatic encephalopathy underlying decompensated liver cirrhosis. Case presentation An 83-year-old woman diagnosed with hepatitis B virus-related liver cirrhosis 40 years before was referred to our neurology clinic for progressive disorientation of time and place, personality changes, and confusion with somnolence over 2 weeks. Based on the laboratory, neuroimaging, and electrophysiological findings, we diagnosed the patient with hepatic encephalopathy, and her symptoms recovered within 12 h after proper medical management. Brain MRI showed innumerable CMBs in the bilateral frontal, parietal, temporal, and occipital lobes. Since the distribution of CMBs in the patient was mainly corticosubcortical and predominantly in the posterior cortical regions, and the apolipoprotein E genotype was ε4/ε4, we speculated that CAA and hepatic encephalopathy coexisted in this patient. Conclusions We suggest that severe liver dysfunction associated with long-term decompensated liver cirrhosis may be related to an increased number of CMBs in the brain. Our findings indicate that decompensated liver cirrhosis may be a risk factor for the development of CMBs and corroborate a link between the liver and the brain.

Abstract
Introduction For unresectable hilar obstruction, restoring and maintaining biliary ductal patency are crucial for improved survival and quality of life. The endoscopic placement of stents is now a mainstay of its treatment, and bilateral stenting is effective for biliary decompression. This study aimed to determine the clinical outcomes of bilateral metal stent placement using large cell-type stents and the clinical predictors of stent dysfunction in patients with malignant hilar obstruction. Methods We performed a retrospective analysis of patients who underwent bilateral metal stent placement using two large cell-type stents at two academic teaching hospitals between September 2017 and February 2019. The primary outcome was stent dysfunction. Secondary outcomes included predictors related to stent dysfunction and overall survival. Results The study included 87 patients who underwent bilateral metal stent placement for malignant hilar obstruction. Technical success and clinical success were achieved in 80 patients (92.0%) and 83 patients (95.4%), respectively. During the follow-up period (median: 201, range: 18–671 days), stent dysfunction occurred in 42 patients (48.3%), and the median stent patency was 199 days (95% confidence interval [CI]: 181–262). In univariate analysis, age, cholangitis before stent insertion, and subsequent chemotherapy were found to be associated with the cumulative risk of stent dysfunction. In multivariate analysis, cholangitis before stent insertion (hazards ratio [HR]: 2.26, 95% CI: 1.216–4.209, P = 0.010) and subsequent chemotherapy (HR: 0.250, 95% CI: 0.130–0.482, P<0.001) remained as statically significant factors associated with the cumulative risk of stent dysfunction. The median overall survival was 288 days (95% CI: 230–327). Conclusion The bilateral placement of large cell-type stents for malignant hilar obstruction was effective with high technical and clinical success rates and acceptable patency. Cholangitis before stent insertion was associated with shorter patency, and subsequent chemotherapy was associated with longer stent patency.

Abstract
Endoscopic ultrasound (EUS)-guided tissue acquisition of pancreatic solid tumor requires a strict recommendation for its proper use in clinical practice because of its technical difficulty and invasiveness. The Korean Society of Gastrointestinal Endoscopy (KSGE) appointed a Task Force to draft clinical practice guidelines for EUS-guided tissue acquisition of pancreatic solid tumor. The strength of recommendation and the level of evidence for each statement were graded according to the Minds Handbook for Clinical Practice Guideline Development 2014. The committee, comprising a development panel of 16 endosonographers and an expert on guideline development methodology, developed 12 evidence-based recommendations in 8 categories intended to help physicians make evidence-based clinical judgments with regard to the diagnosis of pancreatic solid tumor. This clinical practice guideline discusses EUS-guided sampling in pancreatic solid tumor and makes recommendations on circumstances that warrant its use, technical issues related to maximizing the diagnostic yield (e.g., needle type, needle diameter, adequate number of needle passes, sample obtaining techniques, and methods of specimen processing), adverse events of EUS-guided tissue acquisition, and learning-related issues. This guideline was reviewed by external experts and suggests best practices recommended based on the evidence available at the time of preparation. This guideline may not be applicable for all clinical situations and should be interpreted in light of specific situations and the availability of resources. It will be revised as necessary to cover progress and changes in technology and evidence from clinical practice.

Abstract
The most effective and the standard treatment for bile duct stones (BDSs) is endoscopic retrograde cholangiopancreatography (ERCP). However, in 10% to 15% of patients with BDSs, the stones cannot be removed by conventional ERCP, which involves endoscopic sphincterotomy followed by balloon or basket extraction. Additional techniques or devices are often necessary to remove these difficult bileduct stones, including endoscopic papillary large balloon dilatation to make a larger papillary opening and/or mechanical lithotripsy to fragment the stones. Advances in cholangioscopy have made possible electrohydraulic or laser lithotripsy under direct cholangioscopic visualization during ERCP. Cholangioscopy-guided lithotripsy could be another good option in the armamentarium of techniques for removing difficult BDSs. Here we review endoscopic techniques based on single-operator cholangioscopy for the management of difficult BDSs.

Abstract
Background. Radiofrequency ablation (RFA) is a palliative method known for its application in the endoscopic treatment of malignant bile duct obstruction. It may be a useful rescue method for metal stent malfunction caused by tumor ingrowth. This study aimed to examine the feasibility and safety of endoluminal RFA for occluded bilateral hilar metal stents due to tumor ingrowth in patients with malignant hilar bile duct obstruction. Methods: From March 2016 to June 2018, 11 patients with unresectable malignant hilar bile duct stricture with occluded bilateral hilar metal stents due to tumor ingrowth were enrolled. Endoluminal RFA was performed through a novel temperature-controlled catheter at a setting of 7 W power for 120 s with a target temperature of 80 °C via endoscopic retrograde cholangiopancreatography (ERCP). The patients’ demographics, clinical outcomes, and adverse events were investigated. Results: The median age was 64 (interquartile range, 54–72) years. All RFA procedures were successful. Clinical success was achieved in eight patients (72.7%). During the follow-up, eight patients (72.7%) showed stent dysfunction, and the median patency after RFA was 50 days (95% confidence interval (CI): 34–not available (NA)). All stent dysfunctions were successfully managed with ERCP. Ten patients died, and the median overall survival was 289 days (95% CI, 107–NA) from RFA to death. There was one case of mild abdominal pain after the procedure without serious adverse events. Conclusions: As a rescue therapy for occluded bilateral hilar metal stents due to tumor ingrowth, endoluminal RFA seemed to be safe and useful in selected patients.

Abstract
Background Intracholecystic papillary neoplasms (ICPNs) of the gallbladder are rare, preinvasive lesions characterized by an intracholecystic papillary growth that may be associated with invasive adenocarcinoma. The natural history of ICPN is unknown. Here, we report a case of ICPN, highlighting its natural course. Case presentation A 79-year-old woman presented to the emergency department with perforated cholecystitis. After percutaneous transhepatic gallbladder drainage, due to the presence of surgical risk factors, we opted to perform gallstone removal through percutaneous transhepatic cholangioscopy instead of cholecystectomy. ICPN, which was accidentally detected after the removal of the gallbladder stones, was also endoscopically removed. After 4 years, the patient came back to the hospital with a large gallbladder mass. After cholecystectomy, pathological examination revealed ICPN with invasive adenocarcinoma. Conclusion The current case showed endoscopic findings of ICPN and its natural progression, particularly its clinicopathological features and outcomes.

Abstract
OBJECTIVE To evaluate the severity of depression, anxiety, associated risk factors, and cognitive distortion in Korean patients with ulcerative colitis (UC) and Crohn's disease (CD). METHODS This study included 369 patients with inflammatory bowel disease. The severity of depression and anxiety was examined using Patient Health Questionnaire-9 and Hospital Anxiety and Depression Scale. The Anxious Thoughts and Tendencies scale was used to measure catastrophizing tendency. Multivariate regression analyses were performed. RESULTS The predictors of depression were marital status, anti-tumor necrosis factor-α (TNF-α) agent use, age, and body mass index in UC patients and marital status, disease activity, alcohol use, and employment status in CD patients. For anxiety, sex and marital status were the associated factors in UC patients, whereas steroid use was the only significant predictor in CD patients. Comparing the cognitive distortion level, there were no significant differences between UC and CD patients although there was an increasing tendency according to the severity of depression or anxiety. CONCLUSION If patients are accompanied by high levels of depression or anxiety and their associated risk factors including TNF-α agent or steroid use, it is recommended that not only symptoms are treated but also cognitive approach and evaluation be performed.

Abstract
Background/Aims Irreversible electroporation (IRE) is a relatively new ablation method. However, the application of IRE ablation in the treatment of biliary disease has not been attempted. A minimally invasive approach using endoscopic retrograde cholangiopancreatography (ERCP) can be a novel therapeutic modality for IRE ablation. In this study, we aimed to investigate the feasibility of endoscopic IRE for the biliary tract using an animal model.
Methods A new catheter-type electrode was developed for endoscopic IRE ablation of the biliary tract. We performed ERCP and endoscopic IRE ablations in the normal common bile duct of Yorkshire pigs. The experimental setting of IRE was 500 V/cm (50 pulses, 100-µs length). The animals were sacrificed after 24 hr, and the ablated bile duct was examined.
Results Well-demarcated focal color changes were observed on the mucosa of the common bile duct. The depth of change after IRE was confined to the mucosal and submucosal layers. Apoptotic changes in the bile duct were observed only around the IRE ablation area. Immunohistochemistry assay showed cell death in the bile duct along the electrode.
Conclusions Endoscopic IRE ablation using ERCP was successfully performed in the common bile duct. It can be a potential option for the treatment of biliary tumors.

Optimal treatments for patients with advanced hepatocellular carcinoma (HCC) are still limited and their prognosis remains dismal. Yet, there have been rare cases that have shed light on longer survival in these patients assisted by various treatments. This paper aims to present an extraordinary case of far advanced HCC that had been properly managed in spite of continuous recurrence. A patient visited the hospital with a ruptured large HCC with main portal vein tumor thrombosis but survived longer than 14 years owing to active and prompt interventions.

Abstract
Background Regular clinic follow‐up is a prerequisite for optimal antiviral therapy and surveillance of hepatocellular carcinoma in patients with chronic hepatitis B (CHB). However, adherence to regular follow‐up stays low in practice. This study investigated whether regular follow‐up is associated with decreased liver cancer mortality in CHB patients. Methods A nationwide population‐based historical cohort study was conducted using customized data from the National Health Insurance Service of Korea. The number of hospital visits every 3‐month interval was counted for 2 years from the date of CHB diagnosis. Patients were classified into three follow‐up groups: regular (four to eight visits), irregular (one to three visits), and no follow‐up. The risk of liver cancer mortality was compared among the groups using Cox proportional hazard regression analysis. Results Of the 414 074 CHB patients, 22.9% had regular follow‐up. In multivariable analysis, regular follow‐up was independently associated with decreased risk of liver cancer mortality compared to no follow‐up (hazard ratio [HR], 0.56; 95% confidence interval [CI], 0.50‐0.63, P < .001). Regular follow‐up was also associated with the lowest risk of all‐cause mortality (HR, 0.60; 95% CI, 0.57‐0.63, P < .001). Patients with regular follow‐up received more curative treatment (23.1% vs 15.1%, P < .001). Patients were less motivated when they were female, >60 years, of low socioeconomic status, disabled, lived in a rural area, had a higher comorbidity rate, or did not have cirrhosis. Conclusions Regular follow‐up at least every 3‐6 months is significantly associated with reduced liver cancer mortality in patients with CHB.

Abstract
BACKGROUND/AIMS The eradication failure rate of standard triple therapy (proton pump inhibitor, clarithromycin, and amoxicillin) for Helicobacter pylori infection has increased owing to antibiotic resistance in Korea. We assessed whether Saccharomyces boulardii probiotic or broccoli sprout extract sulforaphane supplementation could increase the H. pylori eradication rate and/or reduce antibiotic-associated adverse events. METHODS A total of 217 patients with H. pylori-positive chronic gastritis or peptic ulcer disease were recruited. Clarithromycin resistance was assessed in all patients by testing for A2142G and A2143G point mutations in H. pylori 23S rRNA using a dual-priming polymerase chain reaction (PCR) oligonucleotide. Thirty-four patients (17.3%) were clarithromycin-resistant and were excluded from the study. Finally, 183 patients with infections not resistant to clarithromycin were randomly assigned to triple therapy only (group A, n = 61), triple therapy plus probiotics (group B, n = 61), or triple therapy plus sulforaphane (group C, n = 61) groups. CYP2C19 polymorphisms were examined at position G681A of exon 5 and G636A of exon 4 by PCR with restriction fragment length polymorphism (PCR-RFLP) analysis. H. pylori eradication was assessed by 13C-urea breath test 4 weeks after treatment completion. RESULTS The eradication rates were similar among the groups both in the intention- to-treat (A = 85.2%, B = 89.6%, and C = 81.6%) and per-protocol (A = 89.2%, B = 86.8%, and C = 96.3%) analyses. The frequencies of overall adverse events in the groups also did not differ (A vs. B: p = 0.574; A vs. C: p = 1.000). CONCLUSION Probiotic or sulforaphane with triple therapy for H. pylori infection neither increased the eradication rate nor reduced the occurrence of adverse events.

Abstract
RATIONALE Biliary drainage is essential to resolve jaundice in patients with malignant biliary obstruction. Recently, a biliary self-expandable metal stent (SEMS) with an antireflux valve was developed to prevent enteric-biliary reflux. Its antireflux valve was made of expanded polytetrafluoroethylene (ePTFE), a biostable and biocompatible material. Changes of the ePTFE membrane of medical devices are rarely reported in clinical practice. PATIENT CONCERNS A 59-year-old woman was admitted with a complaint of jaundice. Around 1 month before, she underwent endoscopic biliary stenting using a SEMS with an antireflux valve. DIAGNOSIS Acute cholangitis due to stent clogging was detected on abdominal computed tomography. INTERVENTIONS Endoscopic retrograde cholangiopancreatography and removal of the SEMS with deformity were performed. OUTCOMES The obstructive jaundice was rapidly resolved after the removal of the clogged stent. LESSONS Although the ePTFE membrane is widely used to make medical devices, unexpected changes could occur after the membrane is exposed to bile juice in the duodenum. When performing biliary stenting using a SEMS with an antireflux valve, both the risk of early malfunction and the benefit of the antireflux effect should be considered.

Abstract
This study aimed to analyze the dose of radiation to which the physician is exposed during endoscopic retrograde cholangiopancreatography (ERCP) and to identify predictive factors of radiation exposure during the procedure. Furthermore, we evaluated the patient characteristics and procedural factors associated with prolonged fluoroscopy time (FT).A cross-sectional retrospective analysis of 780 ERCPs performed at a tertiary academic hospital over a 2-year period was conducted. The primary outcome was radiation exposure during ERCP as determined by FT; additionally, the association between variables and radiation exposure was determined. Moreover, we evaluated their correlations with age, sex, body mass index (BMI), diagnosis, duration of procedure, procedure name, and procedure complexity.According to the analysis of the 780 ERCPs performed in 2 years, the mean FT was 5.07 minutes (95% confidence interval [CI], 4.87-5.26). The mean radiation durations were as follows: cholelithiasis, 5.76 minutes (95% CI, 4.75-6.80); malignant biliary obstruction, 6.13 minutes (95% CI, 5.91-6.35); pancreatic disease, 5.28 minutes (95% CI, 4.45-6.28); and benign biliary stricture, 5.32 minutes (95% CI, 5.02-5.94). Significant differences affecting fluoroscopy duration between the 2 endoscopists were not observed in the present study. Multivariate analysis revealed that prolonged fluoroscopy duration was related to specific characteristics, including higher BMI (BMI >27.5 kg/m) (+4.1 minutes; 95% CI, 2.56-5.63), mechanical lithotripsy (+4.85 minutes; 95% CI, 0.45-9.25), needle-knife use (+4.5 minutes; 95% CI, 2.15-6.86), and malignant biliary obstruction (+2.34 minutes; 95% CI, 0.15-4.53).ERCPs are associated with significantly higher radiation exposure of patients on the specific procedure. Endoscopists should be aware of the determining factors, including patients with obesity, who underwent mechanical lithotripsy, who had malignant biliary obstruction, and who underwent a procedure using a needle knife, that affect FT during ERCP.

Abstract
Background Endoscopic nasobiliary drainage (ENBD) is widely used for biliary decompression in patients with biliary disease. However, it is difficult to reposition a nasobiliary catheter from the mouth to nostril. We developed a new device, which has a curved flexible loop and bar-handle, for repositioning of ENBD catheter. The aim of this study was to evaluate the usefulness of the new loop-device for facilitating the repositioning of an ENBD catheter from the mouth to nostril. Methods Between January 2015 and December 2017, a comparative observational study was performed to evaluate the time taken for repositioning a nasobiliary catheter during endoscopic retrograde cholangiopancreatography (ERCP) and compare the results of ENBD procedure between the new loop-device and conventional techniques. In the subgroup analysis, we evaluated the occurrence of oral cavity injury and the time taken to transfer ENBD catheter from the mouth to nostril. Results In all, 145 ENBD procedures were performed using these two techniques. The procedure time was significantly shorter in the new technique group than in the conventional group. (44 s vs. 194 s, p < 0.001). The total success rate of new device technique was 97.3%. No complication, including oral cavity injury, was observed. Conclusions The technique using our new loop-device was useful for repositioning a nasobiliary catheter from the mouth to nostril in ERCP. The new device does not require the removal of the mouthpiece before ENBD positioning, which can help perform the ENBD procedure rapidly and avoid the finger injury of endoscopists.

Abstract
Little is known about the benefits of statin use on liver cancer mortality among patients with chronic hepatitis B (CHB) considering hypercholesterolemia and obesity. A nationwide retrospective cohort study was conducted using data from a Health Examination Cohort of the National Health Insurance Service of Korea. Data on CHB patients with no other concurrent liver disease were acquired, and statin use was defined as a cumulative daily dose ≥28. A 3-year landmark analysis was performed to avoid immortal time bias. Patients who started statin therapy within the landmark date were considered statin users. A Cox regression analysis was applied to assess associations between statin use and liver cancer mortality considering hypercholesterolemia and obesity. Among 13063 patients, 193 (1.5%) died of liver cancer during the mean follow-up period of 10.6 years. After adjusting for demographic and metabolic factors, statin use [hazard ratio (HR), 0.17; 95% confidence interval (CI), 0.04-0.70] and hypercholesterolemia (HR, 0.46; 95% CI, 0.24-0.88 for total cholesterol ≥240 mg/dL) were associated with a decreased risk of liver cancer mortality, whereas body mass index (BMI) ≥30 kg/m² was associated with an increased risk of liver cancer mortality (HR, 2.46; 95% CI, 1.20-5.06). This study showed that statin use was associated with decreased liver cancer mortality when adjusting for cholesterol levels and BMI. This study found that hypercholesterolemia was independently associated with decreased liver cancer mortality regardless of statin use.

Abstract
BACKGROUND/AIMS The eradication rate of the first-line triple therapy (a proton pump inhibitor, clarithromycin, and amoxicillin) for Helicobacter pylori infection has gradually decreased in Korea. We evaluated whether clinical parameters, clarithromycin resistance, and CYP2C19 genotype can affect the eradication failure. METHODS A total of 203 patients with H. pylori-positive chronic gastritis were consecutively enrolled. They received clarithromycin-based triple therapy for 7 days. A clarithromycin resistance test was performed by detection of A2142G and A2143G point mutations in H. pylori 23S rRNA. The CYP2C19 genotype was examined for polymorphism G681A of exon 5 and G636A of exon 4 by polymerase chain reaction with restriction fragment length polymorphism. Eradication was assessed by a 13C-urea breath test 4 weeks after treatment. RESULTS Of 203 patients, 190 completed the study. The eradication rate was 64.0% according to intention-to-treat analysis and 68.4% by per-protocol analysis. CY-P2C19 genotypes were identified as follows: 75 poor metabolizers, 75 intermediate metabolizers, and 40 rapid metabolizers. Nonetheless, this polymorphism was not significantly associated with eradication failure (p = 0.682). Clarithromycin resistance was detected in 33/190 patients (17.4%), and their eradication rate was zero. Clarithromycin resistance (odds ratio [OR], 19.13; 95% confidence interval [CI], 9.35 to 35.09) and female gender (OR, 1.73; 95% CI, 1.15 to 4.25) were significantly associated with eradication failure. The other clinical parameters such as age, cigarette smoking, alcohol intake, the body mass index, hypertension, and diabetes were not significantly associated with eradication. CONCLUSION Clarithromycin resistance and female gender are factors affecting H. pylori eradication failure in patients with chronic gastritis.

Abstract
Background and aims: The impact of cytomegalovirus (CMV) colitis on long-term outcomes of ulcerative colitis (UC) flares remains controversial. Methods: A total of 257 UC patients with moderate-to-severe flares were observed for a mean follow-up of 41.2 months. CMV colitis was defined as histopathologic confirmation of CMV inclusions obtained from macroscopic endoscopic lesions in patients with UC flares. An independent gastrointestinal pathologist prospectively reviewed all specimens. A poor outcome was defined as any of hospitalization, colectomy or death during the follow-up period. Results: The prevalence of CMV colitis was 14% (36/257) over the 10-year study period (2007-2016). When compared to the controls, patients with CMV colitis were characterized by older age, higher disease activity, endoscopic deep ulcerations and more frequent use of immunosuppressive drugs (all p < .05). In total, 57 outcome events (50 hospitalizations, seven colectomies) were observed among the study population (44.7% in patients with CMV colitis vs. 18.9% in controls). The cumulative probability of a poor outcome was significantly greater in the patients with CMV colitis than in the controls (log-rank test p < .001). In a multivariable analysis, CMV colitis remained as an independent predictor of a poor outcome (hazard ratio; 2.27; 95% confidence interval: 1.12-4.60). Despite a generally favorable response to antiviral therapy (79%), the risk of recurrent CMV colitis remained quite high (57%). Most of the recurrences developed within 8 months (75%). Conclusions: True CMV colitis is a poor prognostic indicator among patients with UC flares. An effective strategy for managing recurrent CMV colitis is urgently needed (KCT0003296).

Abstract
BACKGROUND The serum alanine aminotransferase (ALT) level has been used to identify at-risk patients with chronic hepatitis B (CHB) who need antiviral therapy. However, the level associated with increased liver-related mortality requiring active treatment is still unclear. METHODS We used a Health Examination Cohort of the National Health Insurance Service of Korea that included approximately 0.5 million individuals aged 40-79 years. In total, 12 486 patients with CHB and no other concurrent liver disease were enrolled, and patients' liver-related mortality, including that owing to liver cancer, was investigated over 9 years. RESULTS The serum ALT level was correlated positively with liver-related mortality. The rates in men were 0.14, 0.17, 0.24, 0.57, 0.63 and 0.85 per 100 person-years (%) for serum ALT levels of <20, 20-29, 30-39, 40-49, 50-79 and ≥80 U/L, respectively, and the corresponding liver-related mortality rates in women were 0.03%, 0.09%, 0.12%, 0.63%, 0.65% and 0.32%. In patients with ALT levels of 40-79 U/L, the liver-related mortality rates were 0.60% in men and 0.64% in women, which were similar to the overall mortality rate of age- and sex-matched subjects without CHB (0.69%). The best cut-off values for liver-related mortality prediction were >34 U/L in men and >30 U/L in women. CONCLUSIONS The liver-related mortality rate increased significantly, even in CHB patients with relatively low serum ALT levels. Careful monitoring or earlier antiviral therapy should be considered for patients aged >40 years with serum ALT levels above the upper limit of normal.

Abstract
Basal ganglia have complex functional connections with the cerebral cortex and are involved in motor control, executive functions of the forebrain, such as the planning of movement, and cognitive behaviors based on their connections. The aim of this study was to provide detailed functional correlation patterns between the basal ganglia and cerebral cortex by conducting an interregional correlation analysis of the 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) data based on precise structural information. Fifteen participants were scanned with 7-Tesla magnetic resonance imaging (MRI) and high resolution research tomography (HRRT)-PET fusion system using 18F-FDG. For detailed interregional correlation analysis, 24 subregions of the basal ganglia including pre-commissural dorsal caudate, post-commissural caudate, pre-commissural dorsal putamen, post-commissural putamen, internal globus pallidus, and external globus pallidus and 80 cerebral regions were selected as regions of interest on the MRI image and their glucose metabolism were calculated from the PET images. Pearson's product-moment correlation analysis was conducted for the interregional correlation analysis of the basal ganglia. Functional correlation patterns between the basal ganglia and cerebral cortex were not only consistent with the findings of previous studies, but also showed new functional correlation between the dorsal striatum (i.e., caudate nucleus and putamen) and insula. In this study, we established the detailed basal ganglia subregional functional correlation patterns using 18F-FDG PET/MRI fusion imaging. Our methods and results could potentially be an important resource for investigating basal ganglia dysfunction as well as for conducting functional studies in the context of movement and psychiatric disorders.

Abstract
Background Mannose-binding lectin (MBL) acts in the innate immune response to Helicobacter pylori. Interleukin 8 (IL-8) is a potent cytokine produced by gastric epithelial cells in response to H. pylori. We aimed to investigate whether polymorphisms in MBL2 and IL-8 influence susceptibility to H. pylori infection, and the associations of these polymorphisms with the risk of gastroduodenal diseases in a Korean population. Methods We consecutively enrolled 176 H. pylori-negative control subjects, 221 subjects with H. pylori-positive non-atrophic gastritis, 52 mild atrophic gastritis (AG), 61 severe AG, 175 duodenal ulcer, and 283 gastric cancer (GC). Allele-specific PCR-RFLP was conducted for polymorphisms in MBL2 exon 1 (codon 52, 54, and 57) and IL-8 -251 T > A. IL-8 levels in gastric mucosal tissues and serum MBL levels were measured by enzyme-linked immunosorbent assay. Results MBL2 exon 1 polymorphic variants were found only in codon 54, and the allele frequencies did not differ significantly between the control and disease groups. Although serum MBL levels in codon 54 A/A mutants were markedly low, it did not influence susceptibility to H. pylori infection or the risk of gastroduodenal diseases. IL-8 levels were significantly different between T/T wild type, T/A heterozygote, and A/A mutant genotypes. IL-8 -251 A allele carriers (A/A + T/A) showed increased IL-8 levels, and were significantly associated with the risk of severe AG and GC. Conclusions We suggest that a combination of H. pylori infection and the IL-8 -251 T > A polymorphism might increase the risk of severe AG and GC in a Korean population.

Abstract
BACKGROUND/AIMS Lactose-free milk (LFM) is available for nutrient supply for those with lactose intolerance (LI). However, there are no consistent results of the efficacy of LFM in LI subjects. We aimed to examine the changes of gastrointestinal (GI) symptoms and hydrogen breath test (HBT) values after ingestion of lactose contained milk (LCM) vs. LFM. METHODS From May 2015 to September 2015, thirty-five healthy adults with history of LCM-induced GI symptoms were recruited at a tertiary hospital. For the diagnosis of LI, HBT with LCM 550 mL (lactose 25 g) was performed every 20 minutes for 3 hours. The test was defined as "positive" when H2 peak exceeded 20 ppm above baseline values (ΔH2>20 ppm). When the subjects are diagnosed as LI, the second HBT using LFM 550 mL (lactose 0 g) was performed 7 days later. Subjects were asked to complete a questionnaire about the occurrence and severity of GI symptoms. RESULTS Among a total of 35 subjects, 31 were diagnosed with LI at first visit, and their LCM-related symptoms were abdominal pain (98.6%), borborygmus (96.8%), diarrhea (90.3%), and flatus (87.1%). The ΔH2 value in subjects taking LCM (103.7±66.3ppm) significantly decreased to 6.3±4.9 ppm after ingesting LFM (p<0.0001). There were also significant reduction in total symptom scores and the severity of each symptom when LCM was changed to LFM (p<0.0001). CONCLUSIONS This is the first report that LFM reduce LCM-related GI symptoms and H2 production in Korean adults. LFM can be an effective alternative for LCM in adults with LI.

Abstract
The optical bistability (OB) and multistability (OM) in chiral molecules are investigated by placing the sample into a unidirectional ring cavity. Because of broken mirror symmetry of the effective potential, the chiral molecules have a cyclic three-level Δ-configuration structure, in which one- and two-photon transitions can coexist. We find that the OB is achievable in this system on exact one-, two- and three-photon resonance conditions but absent in the three-level Λ-type system under the two-photon resonance. Moreover, the OM and the switching between OB and OM are also realized by choosing parameters properly. Interestingly, the left- and right-handed chiral molecules exhibit different bistable and multistable behaviors. It is shown that the threshold intensity of OB is strongly dependent on the percentage of the two enantiomers in the mixture. This provides an effective approach to probe molecular chirality and to determine enantiomer excess, which may find potential application in organic chemistry, pharmacology, biochemistry, etc..

Abstract
BACKGROUND During treatment for peptic ulcer bleeding (PUB), it is imperative to determine the effect of antiplatelet agents on recurrent bleeding in order to balance risks and benefits. AIMS We compared the rate of recurrent bleeding in antiplatelet users and non-users. METHODS This retrospective study analyzed prospectively collected data from PUB patients treated by endoscopic modalities between August 2007 and December 2014. We evaluated and compared the rate of recurrent bleeding within 30 days in antiplatelet users and non-users; we also categorized antiplatelet users into continuation (≤3 days) and withdrawal (>3 days) groups. RESULTS A total of 490 patients were enrolled in the study, 302 (61.6 %) and 188 (38.4 %) in the non-user and antiplatelet user groups, respectively. The recurrent bleeding rate among antiplatelet users (10.1 %) was significantly higher than that among non-users (5.0 %; p = 0.029). Among 188 antiplatelet users, 51 (27.1 %) and 137 (72.9 %) were assigned to the continuation and withdrawal groups, respectively. The rate of recurrent bleeding did not differ significantly between groups (11.7 vs. 5.9 %, p = 0.241). Multivariate analysis revealed chronic kidney disease as a risk factor [odds ratio (OR) 2.890, 95 % confidence interval (CI) 1.079-7.742, p = 0.035]. However, antiplatelet use (OR 1.691, 95 % CI 0.813-3.517, p = 0.160) was not. CONCLUSIONS This study highlights the need for clinicians to consider underlying diseases in antiplatelet users under the appropriate antiplatelet therapy during the post-hemostasis period. Furthermore, the optimal time to resume antiplatelet agents may be 3 days after successful endoscopic hemostasis in patients with PUB.

Abstract
AIMS Inflammatory processes are involved in bone remodeling. C-reactive protein (CRP) is an acute phase reactant that reflects different degrees of inflammation. Accumulating evidence suggests that CRP is an inflammatory marker and a direct cause of disease. Therefore, we examined the direct effects of CRP on bone cells. MAIN METHODS We used RAW 264.7 cells to evaluate the direct effects of CRP on osteoclast differentiation. We carried out alkaline phosphatase (ALP) and bone nodule formation assays using MC3T3-E1 cells to evaluate osteoblast differentiation. Expression of osteoclast-specific and osteoblast-specific genes and effects on cell signaling pathways associated with cell differentiation were analyzed by reverse transcription polymerase chain reaction and Western blotting. KEY FINDINGS CRP significantly and dose-dependently inhibited TRAP-positive multinucleated cell formation in RANKL-induced RAW 264.7 cell cultures. We observed suppression of p38, ERK and AKT mitogen-activated protein kinases induced by RANKL in Western blots after CRP treatment of RAW 264.7 cells. CRP also suppressed ALP activity and mineralization by Alizarin red S staining of MC3T3-E1 cell cultures. CRP suppressed osteoclast-specific and osteoblast-specific genes. Furthermore, CRP increased interferon beta (IFN-β) mRNA expression and protein levels in RAW 264.7 and MC3T3-E1 cells, and these effects were suppressed by oxPAPC, an inhibitor of Toll-like receptor (TLR) signaling. SIGNIFICANCE These data indicated that CRP may have a direct role on osteoclast and osteoblast differentiation via TLR signaling pathways.

Abstract
A 53-year-old woman was admitted with epigastric discomfort and weakness. Laboratory examination at admission showed mild anemia and proteinuria. Esophagogastroduodenoscopy revealed marked mucosal atrophy, diffuse nodularity and granular appearance with mucosal friability. Biopsy was performed on the antrum and body of the stomach. On the next day, the patient began to complain of severe dyspnea, and hypoxia was present on pulse oximetry. Therefore, emergency echocardiography was conducted and it showed restrictive cardiomyopathy along with thrombus in the left atrium. With time, heart failure was aggravated despite intensive management. The result of gastric biopsy revealed amyloid deposits which stained positively with Congo red. On immunohistochemistry study, kappa and lambda chain were present. In addition, kappa chain was significantly elevated in urine and serum on electrophoresis. Although the patient was finally diagnosed as having primary gastric amyloidosis with restrictive cardiomyopathy, her general condition rapidly deteriorated and died at 12th hospital day. When obscure gastric lesion is encountered, performing gastric biopsy is strongly recommended since it be primary gastric amyloidosis. Herein, we present an unusual case of primary gastric amyloidosis.
