Background/Aims@#The newly derived simplified magnetic resonance index of activity (MARIAs) has not been verified in comparison to balloon-assisted enteroscopy (BAE) for patients with small bowel Crohn’s disease (CD). We studied the correlation of MARIAs with simple endoscopic scores for CD (SES-CD) of the ileum based on magnetic resonance enterography (MRE) and BAE in patients with small bowel CD. @*Methods@#Fifty patients with small bowel CD who underwent BAE and MRE concurrently within 3 months from September 2020 to June 2021 were enrolled in the study. The primary outcome was the correlation between the active score of ileal SES-CD (ileal SES-CDa)/ileal SES-CD and MARIAs based on BAE and MRE. The cutoff value for MARIAs identifying endoscopically active/ severe disease, defined as ileal SES-CDa/ileal SES-CD of 5/7 or more, was analyzed. @*Results@#Ileal SES-CDa/ileal SES-CD and MARIAs showed strong associations (R=0.76, p<0.001; R=0.78, p<0.001). The area under the receiver operating characteristic curve of MA-RIAs for ileal SES-CDa ≥5 and ileal SES-CD ≥7 was 0.92 (95% confidence interval, 0.88 to 0.97) and 0.92 (95% confidence interval, 0.87 to 0.97). The cutoff value of MARIAs for detecting active/ severe disease was 3. A MARIAs index value of ≥3 identified ileal SES-CDa ≥5 with a sensitiv-ity of 85% and specificity of 87% and detected ileal SES-CD ≥7 with a sensitivity of 87% and specificity of 86%. @*Conclusions@#This study validated the applicability of MARIAs compared to BAE-based ileal SES-CDa/SES-CD.

Ectopic pancreas refers to presence of pancreatic tissue in locations other than the pancreas (the usual anatomical site). This condition is often asymptomatic but can occasionally cause abdominal pain or other gastrointestinal symptoms. Ectopic pancreatic tissue is mainly observed in the stomach and duodenum and may be accompanied by complications, such as hemorrhage, pancreatitis, gastric outlet obstruction due to pseudocyst, and malignant transformation. We report a rare case of gastric ectopic pancreas accompanied by a pseudocyst that led to gastric outlet obstruction, which improved after endoscopic ultrasonography guided fine-needle aspiration in a young woman with habitual excessive alcohol consumption.

Objectives@#Endoscopic submucosal dissection (ESD) is a widely used approach for the resection of superficial gastric neoplastic lesions. Endoscopic mucosal resection (EMR) is acceptable for lesions <10–15 mm in size. Herein, we compared the clinical outcomes of ESD with those of EMR after circumferential precutting (EMR-P) for gastric adenomas ≤15 mm. @*Methods@#We retrospectively analyzed the data of 213 patients with 228 gastric adenomas ≤15 mm in size who were treated endoscopically at a single tertiary hospital in Korea between November 2018 and October 2022. We evaluated the complete endoscopic resection rate, recurrence rate, procedurer-elated complications, and procedure time according to the procedure used. @*Results@#Among the 228 gastric adenomas, 49 were treated with EMR-P and 179 with ESD. The histological complete resection rate was higher in the ESD group than in the EMR-P group (87% vs. 57%, p<0.001). No significant between-group differences were observed in endoscopic en bloc resection rates (ESD vs. EMR-P, 96% vs. 90%; p=0.081). The procedure time was significantly shorter in the EMR-P group than in the ESD group (28.9±19.7 min vs. 8.8±5.9 min, p<0.001). The local recurrence rate in patients with histologically incomplete resection did not differ between the two groups (ESD vs. EMR-P, 8.7% vs. 9.5%; p=0.924). @*Conclusions@#For gastric adenomas ≤15 mm, EMR-P may be the preferable treatment method considering the en bloc resection rate, procedure time, and local recurrence rate. However, considering the complete resection rate, ESD is recommended as the treatment of choice for high-grade adenomas and early gastric cancer lesions.

Phlebosclerotic colitis is a rare form of intestinal ischemia. It is caused by calcified peripheral mesenteric veins and a thickened colonic wall. These characteristic findings can be identified on CT and colonoscopy. A 37-year-old female with a history of long-term herbal medicine use presented with acute lower abdominal pain and vomiting of sudden onset. Colonoscopic findings showed dark-blue discolored edematous mucosa and multiple ulcers from the ascending colon to the sigmoid colon. Abdominal CT findings showed diffuse thickening of the colonic wall and calcifications of the peripheral mesenteric veins from the ascending colon to the sigmoid colon. Based on these findings, the patient was diagnosed with phlebosclerotic colitis. We report this rare case of phlebosclerotic colitis in a healthy young female patient with a history of long-term herbal medicine use and include a review of the relevant literature.

Background@#An association between environmental pollutants and alcohol-related liver disease (ALD) has not been determined until now. The objectives of this study were to examine the association of the pollutants with ALD, and whether the pollutants together increased the risk of ALD. @*Methods@#Data were extracted from the Korea National Health and Nutrition Examination Survey (2010–2013 and 2016–2017; n = 11,993). Blood levels of lead, cadmium, and mercury were measured. ALD was defined by a combination of excessive alcohol consumption and ALDon-alcoholic fatty liver disease index > 0. The aspartate aminotransferase-to-platelet ratio index and fibrosis (FIB)-4 score were used to evaluate ALD FIB. @*Results@#The odds ratios (ORs) of ALD for the highest versus the lowest quartiles of exposure were for lead, 7.39 (95% confidence interval [CI], 5.51–9.91); cadmium, 1.68 (95% CI, 1.32–2.14); and mercury, 5.03 (95% CI, 3.88–6.53). Adjusting for age, gender, smoking, occupation, education, and personal income attenuated the associations but indicated significant positive trends (all P trend < 0.001). A positive additive interaction between cadmium and lead was observed. The relative excess OR due to the interaction was 0.96 (95% CI, 0.41–1.51); synergy index = 2.92 (95% CI, 0.97–8.80). Among 951 subjects with ALD, advanced FIB was associated with lead and cadmium (OR, 3.46, 95% CI, 1.84–6.53; OR, 8.50, 95% CI, 2.54–28.42, respectively), but not with mercury. The effect estimates for lead and cadmium remained significant even after adjustment for daily alcohol intake. @*Conclusion@#Blood levels of lead, cadmium, and mercury were significantly associated not only with the risk of ALD but also with ALD FIB. Cadmium and lead have synergistic effects that increase the risk of ALD.

Background/Aims@#Previous studies have reported an association between Helicobacter pylori (H. pylori) infection and nonalcoholic fatty liver disease (NAFLD). Our study examined whether eradication for H. pylori infection reduces the risk of incident NAFLD. @*Materials and Methods@#This retrospective cohort study examined 3,780 adults who had no NAFLD at baseline but were infected with H. pylori. The study population was followed from January 1995 until January 2020. H. pylori infection was determined by an H. pylori-specific IgG antibody test. Fatty liver was diagnosed by ultrasound. @*Results@#During a median follow-up of 7.9 years, 1,294 participants developed NAFLD. In a multivariable model adjusted for age, sex, BMI, smoking status, alcohol intake, and metabolic variables, the uneradicated (for H. pylori) group exhibited a higher risk of incident NAFLD than the eradicated group (hazard ratio [HR], 1.36; 95% CI, 1.18~1.56). The multivariable analysis also demonstrated that higher BMI, current smoking and several metabolic abnormalities were significant risk factors for NAFLD. Subgroup analyses revealed that persistent H. pylori infection correlated with an increased risk of NAFLD. H. pylori eradication was associated with a decreased risk of NAFLD development. @*Conclusions@#H. pylori infection may have a pathophysiological role in NAFLD development. Hence, successful eradication of H. pylori decreases the risk of incident NAFLD.
摘要
Colonoscopy is commonly used to screen for and diagnose colorectal disease, and adequate bowel preparation is crucial to its quality. As bowel preparation regimens vary, it is important that clinicians understand each and select the proper one for each patient.Accordingly, here we investigated recent studies and describe how to choose the optimal bowel preparation regimen. We detail composition, dosages, efficacy, contraindications, and precautions of commonly used regimens including 4 L polyethylene glycol (PEG), 2 L PEG+ascorbic acid, 1 L PEG+ascorbic acid, trisulfate (oral sulfate solution/ tablets), and sodium picosulfate/magnesium citrate. Here we describe that the most recently introduced 1 L PEG and oral sulfate tablets, which were developed to improve convenience and compliance, differ in composition and efficacy between South Korea and foreign countries. This review presents new evidence of and differences among products to increase clinician understanding.
