Abstract
BACKGROUND & AIMS The QUASAR Phase 2b Induction Study evaluated the efficacy and safety of guselkumab, an interleukin-23p19 subunit antagonist, in patients with moderately to severely active ulcerative colitis (UC) with prior inadequate response and/or intolerance to corticosteroids, immunosuppressants, and/or advanced therapy. METHODS In this double-blind, placebo-controlled, dose-ranging, induction study, patients were randomized (1:1:1) to receive intravenous guselkumab 200 or 400 mg or placebo at weeks 0/4/8. The primary endpoint was clinical response (compared with baseline, modified Mayo score decrease ≥30% and ≥2 points, rectal bleeding subscore ≥1-point decrease or subscore of 0/1) at week 12. Guselkumab and placebo week-12 clinical nonresponders received subcutaneous or intravenous guselkumab 200 mg, respectively, at weeks 12/16/20 (uncontrolled study period). RESULTS The primary analysis population included patients with baseline modified Mayo scores ≥5 and ≤9 (intravenous guselkumab 200 mg, n = 101; 400 mg, n = 107; placebo, n = 105). Week-12 clinical response percentage was greater with guselkumab 200 mg (61.4%) and 400 mg (60.7%) vs placebo (27.6%; both P < .001). Greater proportions of guselkumab-treated vs placebo-treated patients achieved all major secondary endpoints (clinical remission, symptomatic remission, endoscopic improvement, histo-endoscopic mucosal improvement, and endoscopic normalization) at week 12. Among guselkumab week-12 clinical nonresponders, 54.3% and 50.0% of patients in the 200- and 400-mg groups, respectively, achieved clinical response at week 24. Safety was similar among guselkumab and placebo groups. CONCLUSIONS Guselkumab intravenous induction was effective vs placebo in patients with moderately to severely active UC. Guselkumab was safe, and efficacy and safety were similar between guselkumab dose groups. CLINICALTRIALS gov number: NCT04033445.

Abstract
The role of heat shock protein 60 (HSP60), a mitochondrial chaperone, in tumor progression or its anti-tumor effects remains controversial. This study aimed to confirm the possibility of using HSP60 as a prognostic marker in patients with colorectal cancer (CRC), considering TNM classification for precise prediction. HSP60 expression increased with differentiation and p53 mutations in patients. However, compared to patients with high HSP60 expression, patients with low HSP60 expression had event-free survival and disease-specific survival hazard ratios (HRs) of 1.42 and 1.69, respectively. Moreover, when the survival rate was analyzed by combining TNM classification and HSP60 expression, the prognosis was poor, particularly when HSP60 expression was low in the late/advanced stage. This pattern was also observed with HSP family D member 1, HSPD1, the gene that encodes HSP60. Low HSPD1 expression was linked to lower overall survival and relapse-free survival rates, with HRs of 1.80 and 1.87, respectively. When TNM classification and HSPD1 expression were considered, CRC patients with low HSPD1 expression and advanced malignancy had a poorer prognosis than those with high HSPD1 expression. Thus, HSPD1/HSP60 can be a useful biomarker for a sophisticated survival prediction in late- and advanced-stage CRC, allowing the design of individualized treatment strategies.

Abstract
BACKGROUND Colon and rectal cancers are among the top five cancers worldwide in terms of their incidence and mortality rates. As the treatment options for cure include surgery even in specific advanced-stage cases, the early detection of lesions is important for applying active treatment methods. Fluorine-18 fluorodeoxyglucose (F-18 FDG) positron emission tomography/computed tomography (PET/CT) is an established imaging study for many types of cancers; however, physiologic uptake in the gastrointestinal tract is a frequent finding and may interfere with lesion identification. Nevertheless, as unexpectedly observed focal colorectal F-18 FDG uptake may harbor malignant lesions, further examination must not be avoided.
AIM To assess the clinical implications of unexpected focal colorectal F-18 FDG uptake by analyzing FDG PET parameters.
METHODS A total of 15143 F-18 FDG PET/CT scans performed at our hospital between January 2016 and September 2021 were retrospectively reviewed to identify incidentally observed focal colorectal FDG uptake. Finally, 83 regions showing focal colorectal FDG uptake with final histopathological reports from 80 patients (45 men and 35 women with mean ages of 66.9 ± 10.7 years and 63.7 ± 15.3 years, respectively) were eligible for inclusion in the present study. Each focal hypermetabolic colorectal region was classified as malignant, premalignant, or benign according to the histopathological report. PET parameters such as maximum and peak standardized uptake value (SUVmax and SUVpeak), metabolic tumor volume (MTV), mean SUV of the metabolic tumor volume (mSUVmtv), and total lesion glycolysis (TLG) were measured or calculated for the corresponding hypermetabolic regions. Parametric and non-parametric statistical comparisons of these parameters were performed among the three groups. Receiver operating characteristic curves were plotted to identify cut-off values.
RESULTS The detection rate of incidental focal colorectal uptake was 0.53% (80/15,143). Of the 83 regions with unexpected focal colorectal hypermetabolism, 28.9% (24/83) were malignant, 32.5% (27/83) were premalignant, and 38.6% (32/83) were benign. Overall, 61.4% of the regions had malignant or premalignant lesions. SUVmax, SUVpeak, and mSUVmtv differentiated malignant and/or premalignant lesions from benign lesions with statistical significance (P < 0.05). mSUVmtv3.5 differentiated malignant from benign lesions, with the largest area under the curve (AUC) of 0.792 and a cut-off of 4.9. SUVmax showed the largest AUC of 0.758 with a cut-off value of 7.5 for distinguishing between premalignant and benign lesions. Overall, SUVmax with a cut-off value of 7.6 (AUC: 0.770, 95% confidence interval (CI): 0.668-0.872; sensitivity, 0.686; specificity, 0.688) was a superior parameter for distinguishing between malignant/premalignant and benign lesions or physiologic uptake. No parameters differentiated malignant from premalignant lesions. Moderate or weak positive correlations were observed between the long diameter of the malignant lesions and PET parameters such as SUVpeak and some mSUVmtv.
CONCLUSION Approximately two-thirds (61.4%) of incidental focal hypermetabolic colorectal regions were malignant/premalignant lesions, for which SUVmax was an independent diagnostic parameter. Unexpected suspicious focal colorectal FDG uptake should not be avoided and consideration for further evaluation is strongly recommended not to miss the two-thirds.

Abstract
Cancer cachexia is syndrome accompanying weight reduction, fat loss, muscle atrophy in patients with advanced cancer. Since tumor necrosis factor-α (TNF-α) played pivotal role in cancer cachexia, we hypothesized preemptive administration of TNF-α antibody might mitigate cancer cachexia. Detailed molecular mechanisms targeting muscle atrophy, cachexic inflammation, and catabolic catastrophe were explored whether TNF-α antibody can antagonize these cachexic mechanisms. Stimulated with preliminary finding human antibody, infliximab or adalimumab, significantly inhibited TNF-α as well as their signals relevant to cachexia in mice, preemptive administration of 1.5 mg/kg adalimumab was done in C-26-induced cancer cachexia. Adalimumab significantly mitigated cancer cachexia manifested with significantly lesser weight loss, leg muscle preservation, and higher survival compared to cachexia control (p<0.05). Significant ameliorating action of muscle atrophy were accompanied significant decreases of muscle-specific UPS like atrogin-1/MuRF-1, Pax-7, PCG-1α, and Mfn-2 after adalimumab (p<0.01) and significantly attenuated lipolysis with inhibition of ATGL HSL, and MMPs. Cachexic factors including IL-6 expression, serum IL-6, gp130, IL-6R, JAK2, and STAT3 were significantly inhibited with adalimumab (p<0.01). Genes implicated in cachexic inflammation like NF-κB, c-Jun/c-Fos, and MAPKs were significantly repressed, while mTOR/AKT was significantly increased adalimumab (p<0.05). Conclusively, preemptive administration of adalimumab can be tried in high risk to cancer cachexia.

Abstract
Background: Increased prevalence of antibiotic resistance to Helicobacter pylori (H. pylori) infection worldwide has driven the search for a new therapeutic candidate. Recently, sitafloxacin, a novel 4-quinolone agent, has emerged as a new therapeutic option for H. pylori eradication, in Japan. However, data on its efficacy for H. pylori eradication in Korea are limited. Therefore, we aimed to investigate the therapeutic potential of sitafloxacin as a first-line treatment for patients with Helicobacter infection through gastric tissue culture-based studies. Materials and Methods: We prospectively enrolled treatment-naïve patients with H. pylori infection who visited the Gil Medical Center between March 2015 and March 2018. After obtaining written informed consent from patients, a total of 121 H. pylori strains were collected. We tested the susceptibility of these strains to sitafloxacin, and other antibiotics for Helicobacter eradication, including clarithromycin (CLR), metronidazole (MTZ), amoxicillin (AMX), tetracycline (TET), levofloxacin (LEV), and ciprofloxacin (CIP) using the agar dilution technique. The minimum inhibitory concentration (MIC) of these antibiotics against H. pylori strains were determined. Results: None of the H. pylori strains obtained were resistant to sitafloxacin (MIC > 1, n = 0), while other conventional eradication drugs including CLR, MTZ, AMX, and TET showed 24.8% (n = 30), 30.6% (n = 37), 5.0% (n = 6), and 0.8% (n = 1) resistance, respectively. Compared to the resistance rates of other quinolones (LEV [36.4%, n = 44] and CIP [37.2%, n = 45]), sitafloxacin showed the best antibiotic performance against Helicobacter strains (0%, n = 0). Furthermore, sitafloxacin also inhibited the growth of 14 H. pylori strains (12.4%), which were resistant to both of clarithromycin, and metronidazole, and 27 strains (22.3%) with multidrug resistance. Conclusions: Sitafloxacin might be a new promising candidate for Helicobacter eradication where antibiotic resistance for Helicobacter is an emerging medical burden, such as in Korea.

Abstract
BACKGROUND AND AIM Manual abdominal massage has been shown to effectively treat slow-transit constipation, but it is labor-intensive. To offer an alternative treatment option for constipation, the Bamk-001 automatic abdominal massage device was developed. The aim of this study was to assess the effect of the Bamk-001 device on symptom profiles and colon transit time (CTT) in patients with chronic constipation. METHODS Thirty-seven patients with chronic functional constipation diagnosed using the Rome IV criteria were enrolled prospectively from December 2018 to February 2019. All patients received device-assisted automatic abdominal massage for 15 min twice daily, once in the morning before breakfast and once at night, for 14 days. CTT was measured before and at the end of the study period. Slow-transit constipation and very-slow-transit constipation were defined as CTT ≥ 48 h and ≥ 72 h, respectively. Patients' symptom profiles regarding overall defecation satisfaction and device-related adverse events were analyzed. RESULTS Among the 37 patients, the mean age was 40.1 ± 11.8, and 5.4% (n = 2) were men. The Bamk-001 device significantly improved CTT from 54.0 (33.6-75.6) to 28.8 (18.0-52.8) h (p = 0.001) in patients with chronic constipation. In subgroup analysis, CTT improved significantly from 54.0 (33.6-75.6) to 28.8 (18.0-52.8) h (p = 0.003) and from 88.2 (74.4-124.8) to 45.6 (27.3-74.1) h (p = 0.005) in the slow-transit and very-slow-transit constipation groups, respectively (p = 0.001). Moreover, all patient symptoms were alleviated after treatment. No serious adverse events were reported. CONCLUSION The Bamk-001 automatic abdominal massage device showed significant care efficacy, including the improvement in CTT and symptom profiles in patients with slow-transit constipation. The use of an automatic abdominal massage device as an adjunct in the management of constipation is a potentially beneficial intervention for patients with slow-transit constipation.

Abstract
BACKGROUND Antibiotic resistance to Helicobacter pylori (H. pylori) infection, which ultimately results in eradication failure, has been an emerging issue in the clinical field. Recently, to overcome this problem, an antibiotic sensitivity-based tailored therapy (TT) for H. pylori infection has received attention.
AIM To investigate the efficacy and safety profiles of TT for H. pylori infection treatment compared to a non-bismuth quadruple therapy, concomitant therapy (CT) regimen.
METHODS We included patients (> 18 years) with an H. pylori infection and without a history of Helicobacter eradication who visited the Gil Medical Center between March 2016 and October 2020. After being randomly assigned to either the TT or CT treatment group in 1 to 1 manner, patient compliance, eradication success rate (ESR), and patient-reported side effects profiles were assessed and compared between the two groups. H. pylori infection was diagnosed using a rapid urease test, Giemsa stain, or dual priming oligonucleotide polymerase chain reaction (DPO-PCR). Tailored eradication strategy based through the presence of a 23S ribosomal RNA point mutation. For the TT group, a DPO-PCR test, which detected A2142G and/or A2143G point mutations, and a clarithromycin resistance test were performed. Patients in the clarithromycin-resistant group were treated with a bismuth-containing quadruple combination therapy, while those with sensitive results were treated with the standard triple regimen.
RESULTS Of the 217 patients with a treatment naive H. pylori infection, 110 patients [mean age: 58.66 ± 13.03, men, n = 55 (50%)] were treated with TT, and 107 patients [mean age: 56.67 ± 10.88, men, n = 52 (48.60%)] were treated with CT. The compliance (TT vs CT, 100% vs 98.13%, P = 0.30), and follow-up loss rates (8.18% vs 9.35%, P = 0.95) were not significantly different between the groups. The ESR after treatment was also not statistically different between the groups (TT vs CT, 82.73% vs 82.24%, P = 0.95). However, the treatment-related and patient-reported side effects were significantly lower in the TT group than in the CT group (22.77% vs 50.52%, P < 0.001).
CONCLUSION The DPO-based TT regimen shows promising results in efficacy and safety profiles as a first-line Helicobacter eradication regimen in Korea, especially when physicians are confronted with increased antibiotic resistance rates.

Abstract
Although adequate bowel preparation is essential in screening colonoscopy, patient intolerability to bowel cleansing agents is problematic. Recently, a probiotic mixture solution with bisacodyl emerged to improve patient tolerability. We investigated the efficacy, safety, and patient tolerability profiles of probiotics with bisacodyl versus conventional polyethylene glycol (PEG) solution for bowel preparation for screening colonoscopies in healthy patients in this prospective, randomized, case-control study. In total, 385 volunteers were randomly assigned to receive 2 L of water + 200 mL of probiotic solution (case group, n = 195) or 4 L of PEG solution (control group, n = 190). The efficacy of the bowel cleansing was evaluated using the Ottawa scale system, polyp detection rate, and adenoma detection rate, and the patient tolerability profiles were assessed using a questionnaire. The demographics were not significantly different between groups. When the Ottawa score for each bowel segment was stratified into an adequate vs. inadequate level (Ottawa score ≤ 3 vs. >3), there were no statistical differences between groups in each segment of the colon. There were no significant differences in the polyp and adenoma detection rates between groups (38.42% vs. 32.42, p = 0.30; 25.79% vs. 18.97%, p = 0.11). The case group showed significantly fewer events than the control group, especially nausea, vomiting, and abdominal bloating events. Regarding the overall satisfaction grade, the case group reported significantly more “average” scores (95% vs. 44%, p < 0.001) and were more willing to use the same agents again (90.26% vs. 61.85%, p < 0.001). As patient compliance with bowel preparation agents is associated with an adequate level of bowel cleansing, a probiotic solution with bisacodyl might be a new bowel preparation candidate, especially in patients who show a poor compliance with conventional bowel preparation agents.

Abstract
BACKGROUND AND AIM Generally, colonoscopy is less effective for detecting colorectal adenomas in the right-sided colon compared with the distal colon. Repeat forward-view (RF) examination of the right-sided colon has been suggested to increase the adenoma detection rate (ADR). However, studies investigating the efficacy of RF examination are lacking. Thus, the aim of this study was to determine whether RF examination in the right-sided colon enhances right-sided ADR. METHODS We performed a prospective, randomized controlled trial, including asymptomatic subjects who underwent screening colonoscopy. Subjects were randomized to the RF group, in which the right-sided colon was examined twice in the forward view, or to the standard forward-view (SF) group, in which the right-sided colon was examined once in the forward view. The primary outcome was the right-sided ADR on RF examination of the right-sided colon. RESULTS A total of 640 subjects completed the study protocol (RF group, n = 320; SF group, n = 320). The right-sided ADR in the RF group was significantly higher than that in the SF group (17.5% vs 11.9%, respectively; P = 0.044). In the RF group, an additional 31 adenomas were found, resulting in an increased detection rate of adenomas of 38.3% compared with the first forward view. The ADR of the whole colon was similar between the groups. CONCLUSIONS In our prospective randomized controlled trial, RF examination of the right-sided colon, which can be easily performed in clinical practice, was associated with an increased rate of detection of right-sided ADR.

Abstract
BACKGROUND Anemia is a common extraintestinal manifestation of inflammatory bowel disease (IBD). However, data on the influence of anti-tumor necrosis factor-alpha (anti-TNF-α) agents and iron supplementation on anemia in patients with IBD are sparse. We assessed the effect of iron supplementation in patients with IBD initially treated with an anti-TNF-α agent. METHODS Data from 79 IBD patients who started anti-TNF-α treatment at a tertiary hospital were analyzed. The patients were divided into the anti-TNF-α (n = 52) and anti-TNF-α with iron supplementation (n = 27) groups. Effects on laboratory parameters, the prevalence of anemia, and disease activity were evaluated at baseline (year 0) and 1 year later. RESULTS The hemoglobin (Hb) level significantly increased between years 0 and 1 in both groups [12.0 ± 1.8-13.3 ± 2.0 g/dL in the anti-TNF-α group (p < 0.001) and 9.8 ± 2.4-11.7 ± 2.3 g/dL in the anti-TNF-α and iron supplementation group (p = 0.004)]. In a subgroup analysis of severely anemic patients with IBD, iron supplementation increased the magnitude of the improvement in Hb level (8.5 ± 1.5-11.4 ± 2.1 g/dL; p = 0.001) compared with the anti-TNF-α group (9.3 ± 0.8-11.4 ± 2.7 g/dL; p = 0.081). Disease activity was significantly improved in both groups at year 1 compared with year 0. Persistent anemia was significantly correlated with severe anemia at baseline (p = 0.017). CONCLUSION In anemic patients with IBD, anti-TNF-α agents led to clinically meaningful improvements in anemia independent of iron supplementation. Also, iron supplementation could be helpful in severely anemic patients with IBD.

Abstract
Human epidermal growth factor receptor 2 (HER2) is implicated in several cancers, including gastric cancer. However, limited data are available regarding its clinical significance in early gastric cancer (EGC). We evaluated the clinical significance of HER2 overexpression in patients with EGC. We retrospectively reviewed 727 patients who underwent surgical treatment for EGC between October 2010 and August 2017. HER2 expression was analysed in 680 EGC cases by immunohistochemistry and classified as negative (0 and 1+), equivocal (2+), or positive [overexpression (3+)]. Among patients with differentiated EGC, the number of patients with HER2 overexpression was not significantly different from that of HER2-negative patients in terms of age, sex, tumour size, location, gross type, depth of invasion, presence of lymphovascular invasion (LVI), and presence of lymph node metastasis (LNM). However, in patients with undifferentiated EGC, HER2 overexpression was significantly correlated with LVI and presence of LNM compared with HER2-negative patients. Multivariate analysis indicated HER2 overexpression as a good predictive marker of LNM in patients with undifferentiated EGC. HER2 expression is associated with LNM in undifferentiated EGC. Therefore, the importance of HER2 overexpression in EGC should not be overlooked, and further studies are needed to identify its clinical significance.

Abstract
Background/Aims: Although proton pump inhibitors (PPIs) remain a mainstay for the suppression of gastric acid secretion, long-term PPI use is associated with side effects. However, the genotoxicity associated with long-term PPI use is unclear.Materials and Methods: This prospective observational pilot study enrolled patients who had been on PPIs for >1 year and healthy controls from July 2015 to August 2016. The subjects completed self-report questionnaires pertaining to their drug and medical history, and only those with no medical history and a ≥2-year wash-out period (for drugs other than PPIs) were included. We collected peripheral-blood lymphocytes from long-term PPI users and healthy controls and analyzed the genotoxicity by using the cytokinesis-block micronucleus cytome assay; we also determined the fasting serum levels of pyridoxine, folate, cobalamin, and homocysteine.Results: Ten long-term PPI users and 40 healthy control subjects were enrolled. The median serum pyridoxine, folate, cobalamin, and homocysteine levels were not significantly different between the groups. The median frequencies of micronuclei (MNi), nucleoplasmic bridges (NPBs), and nuclear buds (Nbuds) per 1,000 binucleated cells, in long-term PPI users and healthy controls, were 30.3 and 16.3 (<i>P</i><0.005), 2.5 and 1.8 (<i>P</i><0.005), and 9.3 and 5.0 (<i>P</i><0.005), respectively. Even after adjustment for confounding factors, the OR of the MNi, NPBs, and Nbuds for long-term PPI users compared with healthy control subjects were 14.1 (<i>P</i><0.001), 2.0 (<i>P</i>=0.001), and 1.3 (<i>P</i>=0.3), respectively.Conclusions: Long-term PPI use was significantly associated with an increased risk of genotoxicity after adjustment for age, sex, body mass index, medical history, drug history, and the serum levels of vitamins.

Abstract
BACKGROUND Few studies have compared the efficacy and safety profile of a tailored eradication (TR) strategy based on the presence of a 23S ribosomal RNA point mutation with those of empirical bismuth-based quadruple therapy (EBQT) for first-line eradication of Helicobacter pylori (H. pylori) in Korean patients.
AIM To compare the efficacy and safety of a TR strategy and those of EBQT regimen as first-line eradication therapy for H. pylori.
METHODS This is an open-label, comparative study in which we prospectively enrolled patients over 18 years of age with H. pylori infection and retrospectively reviewed their data. H. pylori-positive patients diagnosed by rapid urease test, Giemsa staining, or dual priming oligonucleotide polymerase chain reaction (DPO-PCR) were enrolled from May 2016 to September 2018 at Gil Medical Center. Patients with H. pylori infection received either a TR regimen or the EBQT regimen. In the tailored therapy group that underwent DPO-PCR testing, patients with A2142G and/or A2143G point mutations were treated with a bismuth-containing quadruple regimen. The eradication rate, patient-reported side effect rate, and H. pylori eradication success rate were evaluated and compared between the groups.
RESULTS A total of 150 patients were assigned to the TR (n = 50) or EBQT group (n = 100). The first-line eradication rate of H. pylori did not differ between the groups (96.0% vs 95.7%, P = 0.9). The rate of eradication-related side effects for TR was 12.0%, which differed significantly from that of EBQT (43.0%) for first-line treatment (P < 0.001).
CONCLUSION DPO-PCR-based TR for H. pylori eradication may be equally efficacious, with less treatment-related complications, compared to EBQT in Korea, where clarithromycin resistance is high.

Abstract
BACKGROUND Increasing levels of antibiotic resistance have reduced the Helicobacter pylori (H. pylori) eradication rates afforded by the standard triple therapy. Thus, 2-wk first-line four-drug regimens must be considered.
AIM To analyze the eradication rates of modified bismuth-containing quadruple therapy (mBCQT) and concomitant therapy (CT), the associated adverse events, and compliance.
METHODS Patients infected with H. pylori were prospectively randomized to receive mBCQT or CT for 2 wk. mBCQT featured a proton pump inhibitor (PPI), bismuth, metronidazole, and tetracycline, taken twice daily. CT included a PPI, clarithromycin, metronidazole, and amoxicillin, taken twice daily. The 13C-urea breath test was performed no earlier than 4 wk after therapy concluded to confirm eradication. If either the histological or rapid urease test was positive, H. pylori infection was diagnosed.
RESULTS The demographic characteristics of 68 patients who received mBCQT and 68 who received CT did not differ significantly. On intention-to-treat analysis, the eradication rate was 88.2% (60/68) in the mBCQT group and 79.4% (54/68) in the CT group (P = 0.162). By per-protocol analysis, the respective eradication rates were 98.4% (60/61) and 93.1% (54/58) (P = 0.199). More CT than mBCQT patients experienced adverse events [33.8% (23/68) mBCQT vs 51.5% (35/58) CT patients, respectively, P = 0.037]. All patients showed good compliance [85.3% (58/68) mBCQT vs 82.4% (56/68) CT patients, P = 0.641].
CONCLUSION The H. pylori eradication rates of the 2-wk mBCQT and CT regimens are high. Most patients show good compliance, and more CT than mBCQT patients experience adverse events.

Abstract
Background/Aims There is limited data to compare the clinical characteristics and recurrence rates between left-sided primary epiploic appendagitis (PEA) versus left-sided acute colonic diverticulitis (ACD), and right-sided PEA versus right-sided ACD, respectively. Methods We retrospectively reviewed the medical records and radiologic images of the patients who presented with left-sided or right-sided acute abdominal pain and had computer tomography performed at the time of presentation showing radiological signs of PEA or ACD between January 2004 and December 2014. We compared the clinical characteristics of left PEA versus left ACD and right PEA versus right ACD, respectively. Results Fifty-six patients (left:right = 27:29) and 308 patients (left:right = 24:284) were diagnosed with symptomatic PEA and ACD, respectively. Left-sided PEA were statistically significantly younger (50.2 ± 15.4 years vs. 62.1 ± 15.8 years, P= 0.009), more obese (body mass index [BMI]: 26.3 ± 2.9 kg/m2 vs. 22.3 ± 3.1 kg/m2 , P< 0.001), and had more tendencies with normal or mildly elevated high-sensitivity C-reactive protein (hsCRP) (1.2 ± 1.3 mg/dL vs. 8.4 ± 7.9 mg/dL, P< 0.001) than patients with left-sided ACD. The discriminative function of age, BMI and CRP between left-sided PEA versus left-sided ACD was 0.71 (cutoff: age ≤ 59 years, sensitivity of 66.7%, specificity of 77.8%), 0.84 (cutoff: BMI > 24.5 kg/m2 , sensitivity of 80.0%, specificity of 80.0%) and 0.80 (cutoff: CRP < 1.8 mg/dL, sensitivity of 72.2%, specificity of 85.7%). Conclusions If patients with left lower quadrant abdominal pain are less than 60 years, obese (BMI > 24.5 kg/m2 ) with or without normal to mild elevated CRP levels (CRP < 1.8 mg/dL), it might be necessary for clinicians to suspect the diagnosis of PEA rather than ACD.

Abstract
PURPOSE IBM Watson for Oncology (WFO) is a clinical decision-support computing system that provides oncologists with evidence-based treatment recommendations for a variety of cancer diagnoses. The evidence-based supported treatment recommendations are presented in three categories: Recommended, representing the Memorial Sloan Kettering Cancer Center (MSKCC) preferred approach; For Consideration, evidence-based alternative treatments; and Not Recommended, alternative therapies that may be unacceptable. We examined the absolute concordance of treatment options with that of the recommendations of a multidisciplinary team of oncologists from Gachon University, Gil Medical Centre, Incheon, South Korea. METHODS We enrolled 656 patients with stage II, III, and IV colon cancer between 2009 and 2016. Cases were processed using WFO and, using retrospective clinical data, outputs were compared with the actual treatment the patient received. Absolute concordance was defined as an alignment of recommendation in the Recommended MSKCC preferred-approach category. Treatment recommendations that were represented in the For Consideration category were not the focus of this study. RESULTS The absolute concordance between the WFO-derived MSKCC preferred approach and Gil Medical Centre treatment recommendations was 48.9%. The percentage of cases found to be acceptable was 65.8% (432 of 656) and the stage-specific concordance rate was 32.5% for patients with stage II disease who had risk factors and 58.8% for patients with stage III disease. Patients 70 years of age and older had a concordance rate of only 20.2%, whereas younger patients had a concordance rate of 63.8% ( P = .0001). CONCLUSION The main reasons attributed to the low concordance rate were age, reimbursement plan, omitting chemotherapy after liver resection, and not recommending biologic agents (ie, cetuximab and bevacizumab).

Abstract
Accurate prediction of lymph node status is of crucial importance in the appropriate treatment planning for patients with early gastric cancer (EGC). Some studies have examined factors predicting lymph node metastasis (LNM) in EGC; however, these studies did not consider sex-specific differences. This study aimed to investigate sex-specific differences in predictive risk factors of LNM in EGC based on surgical specimens. Patients who underwent surgical treatment for EGC between January 2003 and February 2016 were retrospectively evaluated. Patients who underwent previous gastric surgery or treatment for gastric neoplasms were excluded. Finally, 1076 patients treated for EGC were included in the analysis. We analyzed risk factors of LNM by dividing patients into male and female groups. Of 1076 patients (mean age 59.6 years), 69% were men. The overall LNM rate was 9.4%. The LNM rate was lower in men (7.8%) than in women (12.9%). Multivariate analysis showed that elevated type (odds ratio [OR], 2.084; 95% confidence interval [CI]: 1.053–4.125; P = 0.035), submucosal invasion (OR, 2.162; 95% CI: 1.018–4.595; P = 0.045), undifferentiated type (OR, 2.044; 95% CI: 1.107–3.772; P = 0.022), and lymphovascular invasion (LVI) (OR, 7.210; 95% CI: 3.835–13.554; P<0.001) were independent predictive risk factors of LNM in EGC in men. However, only submucosal invasion (OR, 8.772; 95% CI: 2.823–27.259; P<0.001) and LVI (OR, 8.877; 95% CI: 3.861–20.410; P<0.001) were independent predictive risk factors of LNM in EGC in women. Submucosal invasion and LVI were risk factors of LNM in both men and women. However, elevated and undifferentiated types were risk factors in men but not in women. Clinicians should consider these sex-specific differences with regard to individualized management.

Abstract
Cancer cachexia, one of the metabolic syndromes caused by cancer, is a devastating and miserable condition encountered in more than 50% of terminal cancer patients presenting with significant weight loss associated with skeletal muscle atrophy and fat loss. Though cachexia may account for up to 20% of cancer deaths, no significant treatment is still lacking and is of urgent unmet medical need in cancer treatment. Therefore, understanding the underlying molecular mechanisms is essential for anticipating therapeutic approaches. Since the primary events driving cachexia are mediated via either the central nervous system relatedor inflammation related-anorexia, hypoanabolism, and hypercatabolism, therapy usually targets nutritional support to compensate reduced food intake along with some anti-inflammatory agents to cover specific inflammation-related metabolic derangement, and encourages exercise to supplement reduced physical activity, but all proven to be not so effective so far. Therefore, combination therapies such as a standard multi-modal package including an anorexic agent, megestrol acetate, and anti-inflammatory agent coupled with the development of potential novel therapeutics promise a new era in rescuing patients from cancer cachexia. In this review, we propose the potential application of BPC157, one of the active cytoprotective agents isolated from gastric juices for cancer cachexia. Before clinical trial, we introduced the evidence showing BPC157 rescued from cancer cachexia supported with explored mode of actions.

Abstract
BACKGROUND Few maintenance therapeutic options are available for inflammatory bowel disease (IBD). Data on the effects of continuing 5-aminosalicylic acid (5-ASA) treatment in patients who commence on biologics as maintenance treatment remain scarce. We evaluated IBD patient outcomes after continuation/discontinuation of 5-ASA when biologics were administered as maintenance treatment. METHODS We retrospectively reviewed the clinical, laboratory, and imaging data of patients diagnosed with IBD (ulcerative colitis (UC), 763; Crohn's disease (CD), 537) in the Gil Medical Center (GMC) from February 2005 to June 2018. We divided patients administered with biologics as maintenance treatment into those who did and did not continue on 5-ASA and compared the efficacies of the two treatment options using the log-rank test and Cox proportional hazards models. RESULTS Of 1300 total IBD patients, 128 (UC, 63; CD, 65) were prescribed biologics as induction and maintenance treatments. The median follow-up period was 109.5 weeks. All cases were divided into those who did or did not combine 5-ASA with biologics as maintenance treatments. Kaplan-Meier analysis showed that the event-free survival (exacerbation of disease activity) of UC patients treated with biologics and 5-ASA (n = 42) was not significantly lower than that of those taking biologics alone (n = 21) (log rank test, P = 0.68). The same was true of CD patients (n = 42, biologics and 5-ASA; n = 23, biologics only) (log rank test, P = 0.87). CONCLUSIONS Continuation of 5-ASA after initiation of anti-tumor necrosis factor-alpha agents did not improve prognosis in Korean IBD patients compared with that of those who discontinued 5-ASA during maintenance treatment, particularly in patients who experienced more than two disease aggravations.

Abstract
BACKGROUND Colo-colonic intussusception is an uncommon phenomenon in an adult. Adult intussusception accounts for < 5% of total cases, and the colo-colonic type is < 30% of cases. Although surgical management has been the treatment of choice for intestinal intussusception in adults, because most frequent causes for adult intussusception are malignant in origin, the importance of the roles of preoperative colonoscopic evaluation has recently been emerging.
CASE SUMMARY We report an extremely rare case of adult colo-colonic intussusception caused by colonic anisakiasis and successfully treated by endoscopic removal of the Anisakis body. A 59-year-old man visited the emergency department due to 1 day of lower abdominal colicky pain. Abdominopelvic computed tomography (APCT) revealed the presence of mid-transverse colon intussusception without definite necrosis, which was possibly related with colorectal cancer. Because there was no evidence of necrosis at the intussusception site, a colonoscopy was performed to target the colonic lesion and obtain tissue for a histopathological diagnosis. An Anisakis body was found when inspecting the suspicious colonic lesion recorded by APCT. The Anisakis body was removed with forceps assisted by colonoscopy. The patient’s symptoms improved dramatically after removing the Anisakis. A reduced colon without any pathological findings was seen on the follow-up APCT. Without any further treatment, the patient was discharged 5 d after the endoscopy.
CONCLUSION When colonic intussusception without necrosis occurs in an adult, physician should consider a colonoscopy to exclude causes cured by endoscopy.

Abstract
BACKGROUND Jack hammer esophagus is a relatively rare disease and to date, there is no dramatic treatment option. Recently, conventional per-oral endoscopic myotomy (POEM) have expanded their area into Jackhammer esophagus. However, several complications such as post procedure motility disorders (e.g., passage disturbance) are issues after POEM. To overcome these issues, we here introduced high-resolution manometry (HRM)-guided superficial partial circular muscle myotomy, which involves cutting only the superficial layer of the esophageal circular muscle.
CASE SUMMARY We report two cases of patients with Jackhammer esophagus who were treated with HRM-guided extremely superficial partial circular muscle myotomy during POEM. Case 1 was a 53-year-old female with medication-refractory odynophagia and case 2 was a 47-year-old man who presented with chest pain. They were diagnosed with Jackhammer esophagus using HRM, and the hypercontractile segments of the esophagus were identified. HRM-guided extremely superficial partial circular muscle myotomy was performed while preserving the lower esophageal sphincter. Therefore, the circular and longitudinal muscle layers are preserved but hypercontractile movements are reduced, even after POEM. Patients’ clinical symptoms dramatically improved right after POEM, and 6-mo follow-up HRM revealed completely resolved status. During a 1-year follow-up period, patients were still in good health and remained symptom free.
CONCLUSION HRM-guided superficial partial circular muscle myotomy may be a promising alternative to conventional POEM for treating Jackhammer esophagus with improved efficacy.

Abstract
Background/Aim. In Korea, the rate of Helicobacter pylori (H. pylori) eradication has declined steadily as a result of increasing resistance to antibiotics, especially dual resistance to clarithromycin and metronidazole. However, microbiological culture data on drug-resistant H. pylori is lacking. This study evaluated the antimicrobial efficacy of candidate antibiotics against resistant H. pylori strains. Methods. After retrospectively reviewing the data from the Helicobacter Registry in Gil Medical Center (GMC) and Asan Medical Center (AMC), along with 4 reference strains, we selected the 31 single- or multidrug-resistant strains. The susceptibility of the H. pylori strains to seven antibiotics (clarithromycin, metronidazole, levofloxacin, amoxicillin, tetracycline, rifabutin, and furazolidone) and minimum inhibitory concentration were tested using the broth microdilution technique. Results. Among 31 antibiotic resistance strains for H. pylori, there were no strains resistant to rifabutin or furazolidone, which had MICs of <0.008 and 0.5 μg/mL, respectively. Only one tetracycline-resistant strain was found (MIC < 2 μg/mL). Amoxicillin and levofloxacin were relatively less effective against the H. pylori strains compared to rifabutin or furazolidone (resistance rates 22.6%, 1.9%, respectively). Tetracycline showed the relatively low resistance rates (3.2%) for H. pylori strains. Conclusions. Therefore, along with tetracycline which has already been used as a component for second-line eradication regimen for Helicobacter, rifabutin and furazolidone, alone or in combination, could be used to eradicate antibiotic-resistant H. pylori strains where drug-resistant Helicobacter spp. are increasing.

Abstract
BACKGROUND Dysphagia associated with neurologic disorders is a problem worldwide. However, few studies have assessed the efficacy of endoscopic botulinum toxin injections into the cricopharyngeal muscle using a pharyngoscope. METHODS Fourteen patients who received an endoscopic botulinum toxin injection due to cricopharyngeal muscle dysfunction and a neurological disorder from 2006 to 2017 were retrospectively reviewed at a single tertiary medical center. The toxin was injected at a 100 international unit (IU) total dose under direct endoscopic vision. The success of the procedure was evaluated comprehensively using the following: clinical resolution of the previous symptoms, functional oral intake scale (FOIS) for the clinical evaluation of swallowing, and videofluoroscopic swallowing study (VFSS) to check decreased retention of barium at the pyriform sinus and the epiglottic vallecula. RESULTS The study included 12 males and 2 females (mean age, 58 years old; range, 37-82 years). Three patients (21.4%) were confirmed clinically and eleven were confirmed by VFSS. Eleven patients (78.6%) were managed successfully with the injection. Three patients (21.4%) did not improve despite the injection. CONCLUSION An endoscopic botulinum toxin injection may be a good treatment option for patients with dysphagia and cricopharyngeal dysfunction due to a neurological disorder. Large, prospective, long-term follow-up studies are needed in the future.

Abstract
BACKGROUND Watson for oncology (WFO) is a cognitive computing system providing decision support. We evaluated the concordance rates between the treatment options determined by WFO and those determined by a multidisciplinary team (MDT). METHODS We reviewed the medical charts of patients diagnosed with colorectal cancer who visited the MDT at a single tertiary medical center from November 2016 to April 2017. WFO classified the treatment options for specific patients into three categories: 'Recommended', 'For consideration', and 'Not recommended'. Concordance rates between the WFO- and MDT-determined chemotherapy options, and the factors that potentially influence the concordance rate, were analyzed. RESULTS Sixty-nine patients with colorectal cancer met with the MDT from Nov. 2016 to Feb. 2017. The mean age of the patients was 62 years (range: 34-86 years), and more patients were male (47/69) than female. Of the 69 patients, 51 (73.9%) were diagnosed with colon cancer, of whom 46.4% received the same regimen recommendation from WFO ('Recommended') as they did from the MDT. After inclusion of the 'For consideration' category from WFO, the concordance rate increased to 87.0%. The concordance rate between MDT and NCCN guidelines was 97.1%, and that between the WFO and NCCN guidelines was 88.4%. The concordance rates between WFO and MDT were significantly lower in patients with stage II, IIIC, or IV disease (P<0.001), and the colorectal cancer stage was the only statistically significant factor discriminating between WFO and MDT. CONCLUSIONS The concordance rate between chemotherapy regimens for colorectal cancer determined by MDT versus WFO recommendations was 46.4%. After including the 'For consideration' category from WFO, the concordance rate increased to 88.4%. Further modification and improvement of the WFO prioritizing algorithm used to recommend treatment may increase the usefulness of WFO in the clinic.

Abstract
Strongyloides stercoralis is endemic to tropical and subtropical regions, and infections are usually asymptomatic. However, immunocompromised patients, such as those receiving immunosuppressive therapy, high-dose steroids, or chemotherapy, can develop fatal hyperinfections. An 84-year-old man without any symptoms was diagnosed with strongyloidiasis during a regular screening colonoscopy. His medical history only involved a gastric endoscopic submucosal dissection for early gastric cancer 6 months previously. Few cases have been published about asymptomatic strongyloidiasis diagnosed in an immunocompetent host via endoscopic mucosal resection with characteristic colonoscopic findings. We report a case of colon-involved asymptomatic strongyloidiasis with specific colonic findings of yellowish-white nodules. This finding may be an important marker of S. stercoralis infection, which could prevent hyperinfections.

Abstract
Background Studies of the use of CO2 insufflation during endoscopic resection of large colorectal polyps (LCPs) are lacking. Objective We evaluated the effect of CO2 insufflation on pain after endoscopic resection of LCPs. Methods In a prospective randomized controlled trial (RCT), 132 patients were randomly assigned to groups who underwent endoscopic resection with CO2 insufflation (CO2 group, n = 66) or air insufflation (air group, n = 66). The primary outcome was abdominal pain post-procedure (PP). The secondary outcomes were abdominal distension, rates of technical success, amounts of sedatives prescribed, use of analgesics, and adverse events. Results Baseline patient characteristics were similar between the groups. The mean abdominal pain score was 12.3 in the CO2 group vs. 17.5 in the air group at 1 h PP (p = 0.047). Also, the proportion of patients without pain was significantly higher in the CO2 group at 1 h PP (p = 0.008). The pain score differed more in the endoscopic submucosal dissection group and long-time group. The secondary outcomes were not significantly different between the two groups. Conclusions The results of this RCT demonstrate the superiority of CO2 insufflation for endoscopic resection of LCPs in terms of decreasing PP abdominal pain (KCT0001636).

Abstract
Background/Aims Although some previous studies reported that a treatment combined with mucoprotective agent could improve the eradication rate in dual or triple therapy, there are other reports that question the efficacy of combining these drugs in concomitant therapy (CoCTx). The aim of this study was to investigate the effects of rebamipide or ecabet on the Helicobacter pylori (H. pylori) eradication combined with CoCTx. Methods We retrospectively reviewed the medical records of 277 patients with proven H. pylori infection. They were assigned to one of 3 regimens for 10 days, twice daily: (a) CoCTx (n=118): lansoprazole 30 mg, amoxicillin 1 g, metronidazole 500 mg, and clarithromycin 500 mg; (b) CoCTx+rebamipide (100 mg) (n=85); (c) CoCTx+ecabet (1 g) (n=74). Results The baseline characteristics were not significantly different. H. pylori eradication rates were 82.2% (97/118) in CoCTx, 90.6% (77/85) in CoCTx+rebamipide, and 89.2% (66/74) in CoCTx+ecabet (p=0.17), which were statistically insignificant. Overall adverse events were more frequently reported in the CoCTx+rebamipide (50.6%. 43/85) and CoCTx+ecabet (44.6%, 33/74) groups than in the CoCTx (32.2%, 38/118) (p = 0.03) group. Drug compliances were not different between three groups (CoCTx: 95.8%, 113/118; CoCT+rebamipide: 92.9%, 79/85; CoCTx+ecabet 98.6%,73/74) (p=0.209). Multivariate analysis showed that the risk of eradication failure was significantly increased with decreased drug compliance (odds ratio 3.52, 95% confidence interval 1.00-12.32; p=0.05). Conclusions Addition of these mucoprotective agent was not superior to CoCTx alone for eradicating H. pylori infection with frequent adverse events. Rather, drug compliance is the most related factor affecting the eradication rate. Our data suggest the importance of drug compliance over the drugs used.

Abstract
Background/Aims The use of laparoscopic adjustable gastric banding (LAGB) is increasing proportionally with the obesity epidemic. However, some postoperative complications have been highlighted as major problems associated with LAGB. There is no consensus concerning the endoscopic management of these adverse events. The aim of this study was to retrospectively review the feasibility and effectiveness of endoscopic treatment for LAGB complications. Methods We retrospectively evaluated 352 patients who underwent LAGB between 2011 and 2015. LAGB-associated complications developed in 26 patients (7.4%). This study involved six patients (1.7%) who received endoscopic treatment. Results Types of LAGB-induced complications in our series included intragastric migration (n=3), gastric leaks (n=2), and gastric fistulas (n=1). The endoscopic treatment of these complications was successful in four of the six patients. Endoscopic band removal was successful in two patients. All gastric leaks were successfully closed via an endoscopic procedure. In two cases (intragastric migration and gastric fistula), endoscopic treatment was not sufficient, and surgery was performed. Conclusions Endoscopic procedures afforded acceptable treatment of band migration and gastric leaks after LAGB. However, the results were poor in patients with gastric fistula.

Abstract
BACKGROUND AND AIM DA-9701, a newly developed prokinetic agent formulated with Pharbitis Semen and Corydalis Tuber, has been shown to effectively treat functional dyspepsia. Recently, it has also been suspected to improve gastrointestinal motor function. The aims of this study were to assess the effect of DA-9701 on colonic transit time (CTT) and symptoms of functional constipation. METHODS Thirty-three patients with functional constipation based on the Rome III criteria were prospectively enrolled. The patients received 30-mg DA-9701 three times a day for 24 days. CTT was estimated initially and at the end of treatment. Symptoms such as spontaneous bowel movements, straining, stool form, feeling of incomplete emptying and anorectal blockage, abdominal discomfort and pain, overall defecation satisfaction, and incidence of adverse events were also analyzed. RESULTS Twenty-seven patients completed the study. DA-9701 was associated with a significantly reduced CTT from 34.9 ± 17.6 to 23.7 ± 19.1 h (P = 0.001). Segmental CTT also significantly decreased after treatment (right CTT: from 16.8 [0.0-28.8] to 6.0 [0.0-25.2] hours, P < 0.001; rectosigmoid transit time: from 13.2 [0.0-38.4] to 6.0 [0.0-33.6] hours, P = 0.021). In addition, all constipation-related subjective symptoms, including spontaneous bowel movement frequency, significantly improved compared with those before treatment. Serious adverse events did not occur. CONCLUSIONS DA-9701 accelerates colonic transit and safely improves symptoms in patients with functional constipation. Therefore, we suggest that this novel agent could help to treat patients with this condition.

Abstract
RATIONALE Gastrointestinal subepithelial tumors (SETs) with endoscopic features such as ulceration, a red color change, a peeled mucosal layer, and spontaneous bleeding could have malignant potential. However, we encountered a case of a lipoma that presented features different from the generally known features of gastrointestinal SETs. Therefore, we report an interesting rare case of a terminal ileal giant lipoma with a unique feature of spontaneous peeled ulceration on the surface on endoscopy that caused gastrointestinal bleeding. PATIENT An 82-year-old woman with a 1-week history of abdominal pain and hematochezia presented to our hospital. DIAGNOSES Ileocolonoscopy revealed a SET with a peeled surface and erythematous and ulcerative mucosal changes as well as exposed a submucosal mass at the terminal ileum. Macroscopically, the lesion appeared as a yellowish pedunculated polypoid mass measuring 3 × 2 cm with a peeled mucosal ulceration. Histopathological findings revealed a submucosal lipoma of the terminal ileum. INTERVENTION We thought that the endoscopic finding indicated malignant SETs or those with malignant potential rather than benign SETs. Therefore, the patient underwent an elective laparoscopic ileocecectomy. LESSONS We encountered a lipoma that did not present with the typical features of gastrointestinal SETs. Our findings suggest that clinicians should consider that benign SETs in the terminal ileum may present with various endoscopic findings similar to those of malignant SETs, which can cause fatal symptoms and signs.

Abstract
Oral 5-aminosalicylic acid agents (mesalazine and sulfasalazine) and azathioprine are the mainstays of treatment for inflammatory bowel disease. Reports of pulmonary toxicity induced by oral 5-aminosalicylic acid agents or azathioprine in patients with inflammatory bowel disease are very rare; to date, only 38 cases have been reported worldwide. We, herein, report a case involving a 26-year-old man who was diagnosed with eosinophilic pneumonia after using mesalazine and azathioprine for the treatment of Crohn's disease and recovered after treatment. We also found that the fraction of exhaled nitric oxide level was elevated in this patient. After treatment, the fraction of exhaled nitric oxide level decreased and the symptoms improved. The present case shows that fraction of exhaled nitric oxide is related to the disease activity and treatment effectiveness of druginduced eosinophilic pneumonia.

Abstract
UNLABELLED Background and study aims Anticholinergic premedication has not been validated for endoscopic submucosal dissection (ESD). In this randomized, double-blind, placebo-controlled trial, we investigated the efficacy and safety of glycopyrrolate as a premedication for ESD. Methods A total of 196 patients undergoing ESD at a single tertiary medical center between December 2014 and February 2016 were randomly allocated to receive one of the following two premedications: glycopyrrolate (0.004 mg/kg intramuscularly [IM]) or placebo (2.0 mL normal saline solution IM). All patients received the premedication 30 minutes prior to ESD in a double-blind manner. The endoscopists reported the ease of performing the procedure and the incidence of secretion-induced hypoxemia, cough, and other procedure-related adverse events. Results Glycopyrrolate and placebo were received by 96 and 100 patients, respectively. ESD was successfully performed in all patients without any serious adverse events related to sedation or ESD. The median visual analog scale for procedure ease was higher in the glycopyrrolate group at 8 (interquartile range [IQR] 7 - 9) vs. 7 (IQR 6 - 8.25); P < 0.001. The proportions of patients with secretion-induced hypoxemia (4.4 % vs. 14.3 %; P = 0.03) and cough (16.7 % vs. 35.7 %; P = 0.005) were lower in the glycopyrrolate group. Conclusions The use of glycopyrrolate as a premedication for ESD significantly improved the ease of performing the procedure and reduced the incidence of secretion-induced hypoxemia and cough during ESD. Glycopyrrolate may be a promising premedication to ensure safe and stable ESD procedures. TRIAL REGISTRATION Clinical Research Information Service (CRIS): KCT0001540.

Abstract
AIM To evaluate the anti-inflammatory and anti-apoptotic effects of rosuvastatin by regulation of oxidative stress in a dextran sulfate sodium (DSS)-induced colitis model.
METHODS An acute colitis mouse model was induced by oral administration of 5% DSS in the drinking water for 7 d. In the treated group, rosuvastatin (0.3 mg/kg per day) was administered orally before and after DSS administration for 21 d. On day 21, mice were sacrificed and the colons were removed for macroscopic examination, histology, and Western blot analysis. In the in vitro study, IEC-6 cells were stimulated with 50 ng/mL tumor necrosis factor (TNF)-α and then treated with or without rosuvastatin (2 μmol/L). The levels of reactive oxygen species (ROS), inflammatory mediators, and apoptotic markers were measured.
RESULTS In DSS-induced colitis mice, rosuvastatin treatment significantly reduced the disease activity index and histological damage score compared to untreated mice (P < 0.05). Rosuvastatin also attenuated the DSS-induced increase of 8-hydroxy-2’-deoxyguanosine and NADPH oxidase-1 expression in colon tissue. Multiplex ELISA analysis revealed that rosuvastatin treatment reduced the DSS-induced increase of serum IL-2, IL-4, IL-5, IL-6, IL-12 and IL-17, and G-CSF levels. The increased levels of cleaved caspase-3, caspase-7, and poly (ADP-ribose) polymerase in the DSS group were attenuated by rosuvastatin treatment. In vitro, rosuvastatin significantly reduced the production of ROS, inflammatory mediators and apoptotic markers in TNF-α-treated IEC-6 cells (P < 0.05).
CONCLUSION Rosuvastatin had the antioxidant, anti-inflammatory and anti-apoptotic effects in DSS-induced colitis model. Therefore, it might be a candidate anti-inflammatory drug in patients with inflammatory bowel disease.

Abstract
The aim of this study was to elucidate the predictive risk factors of synchronous multiple early gastric cancer regardless of the treatment modality.Patients who underwent early gastric cancer treatment between July 2005 and June 2015 were retrospectively reviewed. In total, 1529 patients who were treated for early gastric cancer were included. We analyzed the patient's data to find predictive factors of synchronous multiple early gastric cancer compared to solitary early gastric cancer. Further analysis was performed to verify the difference between endoscopic and surgical treatment groups.Among the 1529 patients, synchronous multiple early gastric cancer was diagnosed in 68 (4.4%) patients. Significant differences in sex (P = .004), gross appearance (P = .038), depth of invasion (P = .007), and lymphovascular invasion (P = .039) were found between patients with solitary early gastric cancer and synchronous multiple early gastric cancer by univariate analysis. In multivariate analysis, male sex (odds ratio, 2.475; P = .011) and submucosal invasion (odds ratio, 1.850; P = .033) were independent predictive risk factors of synchronous multiple early gastric cancer. In addition, in multivariate analysis, significant differences in age, tumor size, longitudinal location, depth of invasion, and histology were found between patients groups depending on the mode of treatment.Male sex and submucosal invasion were predictive risk factors of synchronous multiple early gastric cancer. Patients with these factors should undergo more meticulous endoscopic surveillance.

Abstract
Background The incidence of colorectal cancer (CRC) is increasing, with metastasis of newly diagnosed CRC reported in a large proportion of patients. However, the effect of Korean Red Ginseng extracts (KRGE) on epithelial to mesenchymal transition (EMT) in CRC is unknown. Therefore, we examined the mechanisms by which KRGE regulates EMT of CRC in hypoxic conditions. Methods Human CRC cell lines HT29 and HCT116 were incubated under hypoxic (1% oxygen) and normoxic (21% oxygen) conditions. Western blot analysis and real-time PCR were used to evaluate the expression of EMT markers in the presence of KRGE. Furthermore, we performed scratched wound healing, transwell migration, and invasion assays to monitor whether KRGE affects migratory and invasive abilities of CRC cells under hypoxic conditions. Results KRGE-treated HT29 and HCT116 cells displayed attenuated vascular endothelial growth factor (VEGF) mRNA levels and hypoxia-inducible factor-1α (HIF-1α) protein expression under hypoxic conditions. KRGE repressed Snail, Slug, and Twist mRNA expression and integrin αVβ6 protein levels. Furthermore, hypoxia-repressed E-cadherin was restored in KRGE-treated cells; KRGE blocked the invasion and migration of colon cancer cells by repressing NF-κB and ERK1/2 pathways in hypoxia. Conclusions KRGE inhibits hypoxia-induced EMT by repressing NF-κB and ERK1/2 pathways in colon cancer cells.

Abstract
Although endoscopic submucosal dissection (ESD) is widely accepted as a curative treatment method for early gastric cancer (EGC) worldwide, metachronous recurrence often occurs after ESD for EGC. However, there are insufficient data about the role of Helicobacter pylori (H. pylori) infection and other risk factors for recurrence. We aimed to compare the metachronous lesion in the H. pylori persistent group and the eradicated group, and to identify risk factors for metachronous lesion. We retrospectively analyzed 782 patients who underwent ESD between January 2008 and December 2013. We excluded patients with dysplasia or patients who were not tested for H. pylori infection. One hundred eighty-five patients were enrolled. We studied risk factors for recurrence, and used survival analysis to test. There were 24 patients with metachronous recurrence after ESD for EGC among the group. The incidence of metachronous gastric lesions after ESD for EGC developed more in the over 70-year-old group (P = 0.025) and more in the H. pylori persistent group (P = 0.008). In conclusion, H. pylori infection and old age are independent risk factors for metachronous gastric lesions after ESD in EGC.

Abstract
Guillain-Barre syndrome (GBS)-associated achalasia is a very rare disease of uncertain cause. We report the case of a patient diagnosed with GBS-associated type I achalasia who was successfully treated with peroral endoscopic myotomy (POEM). A 30-year-old man who was diagnosed with GBS 3 mo before was referred to our department with dysphagia and meal-related regurgitation. The results of esophagography, endoscopy, and high-resolution manometry (HRM) revealed type I achalasia. POEM that utilized a submucosal tunneling technique was performed to treat the GBS-associated type I achalasia. After POEM, smooth passage of a contrast agent into the stomach was shown in follow-up esophagography, and follow-up HRM revealed a decrease in the mean integrated relaxation pressure 22.9 mmHg to 9.6 mmHg. The patient remained without dysphagia for 7 mo, even though the patient’s neurological problems were not fully resolved. POEM may be a safe and effective treatment for GBS-associated type I achalasia.

Abstract
Small bowel injury can occur as the result of a multifaceted process that includes increased acid secretion, generation of reactive oxygen species, and cyclooxygenase inhibition. However, no effective medication for small bowel ulceration is available. Simvastatin is an important lipid-lowering agent with anti-inflammatory activity. We aimed to validate the effects of simvastatin in vitro and in vivo. In presence or absence of simvastatin, IEC-6 small bowel cell line with 50 ng/ml of tumor nectosis factor α (TNF-α) was investigated by western blotting, qRT-PCR, and DCF-DA assay. In addition, an in vivo study of nonsteroidal anti-inflammatory drugs (NSAID)-induced small bowel inflammation was performed using 7-week-old specific-pathogen-free (SPF) male C57BL/6 mice. Simvastatin treatment reduced the mRNA levels of interleukin-6 and interleukin-8 by approximately 50% in TNF-α-stimulated IEC-6 cells. Treatment with a combination of 50 ng/ml TNF-α and μM simvastatin decreased activation of Akt, IκBα, and nuclear factor-κB p65 level in IEC-6 cells. By DCF-DA staining, intracellular reactive oxygen species (ROS) production was increased in TNF-α-stimulated cells, and treatment with simvastatin decreased the level of ROS. In addition, in vivo mouse model of NSAID-induced small bowel inflammation, the administration of simvastatin reduced the number of small bowel hemorrhagic lesions and the level of ROS production as determined by gross examination and 8-hydroxydeoxyguanosine immunohistochemistry of small bowel tissue, respectively. Simvastatin reduced NSAID-induced injuries by both suppression of ROS generation and modulation of inflammatory cytokines in vitro and in vivo. Therefore, simvastatin, an HMG-CoA reductase inhibitor, has potential as a prophylactic and therapeutic agent for NSAID-induced small bowel injury.

Abstract
The detection rate of early gastric cancer (EGC) is increasing due to improvements in diagnostic methods, but synchronous multiple EGC (SMEGC) remains a major problem. Therefore, we investigated the characteristics of and the correlation between the main and minor lesions of SMEGC. We retrospectively reviewed the medical records of patients with EGC between April 2008 and May 2013. The main lesion was defined as the one with the greatest invasion depth. If lesions had the same invasion depth, the tumor diameter was used to define the main lesion. Of 963 patients who had treatment for EGC, 37 patients with SMEGC were analyzed. The main and minor lesions showed a significant positive correlation of size (r = 0.533, P = 0.001). The main and minor lesions of SMEGC showed the same vertical and horizontal locations at 70.3% and 64.9%, respectively (P = 0.002 and P = 0.002). Macroscopic types were identical in 67.6% (P < 0.001), and 32.4% had identical macroscopic type and location. The main and minor lesions had identical characteristics of invasion depth, presence of lymphovascular invasion (LVI), and differentiation in 78.4%, 83.8%, and 83.8%, respectively. Differentiation, LVI, and invasion depth (microscopic characteristics) were simultaneously the same in 62.2%. The location, macroscopic type, and 3 microscopic characteristics were matched in 27%. The main and minor lesions of SMEGC have similar clinicopathologic characteristics. Therefore, the possibility of SMEGC should not be neglected in cases of EGC, considering an understanding of the characteristics and association of lesions.

Abstract
Background/Aims Rectal neuroendocrine tumors (NETs) are among the most common of gastrointestinal NETs. Due to recent advances in endoscopy, various methods of complete endoscopic resection have been introduced for small (≤10 mm) rectal NETs. However, there is a debate about the optimal treatment for rectal NETs. In our study, we aimed to evaluate the efficacy and feasibility of endoscopic resection using pneumoband and elastic band (ER-BL) for rectal NETs smaller than 10 mm in diameter. Methods A total of 55 patients who were diagnosed with rectal NET from January 2004 to December 2011 at Gil Medical Center were analyzed retrospectively. Sixteen patients underwent ER-BL. For comparison, 39 patients underwent conventional endoscopic mucosal resection (EMR). Results There was a markedly lower deep margin positive rate for ER-BL than for conventional EMR (6% [1/16] vs. 46% [18/39], P=0.029). Four patients who underwent conventional EMR experienced perforation or bleeding. However, they recovered within a few days. On the other hand, patients whounderwent endoscopic resection using a pneumoband did not experience any complications. In multivariate analysis, ER-BL (P=0.021) was independently associated with complete resection. Conclusions ER-BL is an effective endoscopic treatment with regards to deep margin resection for rectal NET smaller than 10 mm.

Abstract
Based on the unexpected Middle East respiratory syndrome (MERS) outbreak in Korea, it was established that the virus can spread easily, MERS exposure in hospitals carries an extreme risk for infection as well as mortality, and the sharing of information was essential for infection control. Although the incidence of exogenous infections related to contaminated endoscopes is very low, the majority of published outbreaks have been caused by various shortcomings in reprocessing procedures, including insufficient training or awareness. Ever since the inauguration of "Clinical Endoscopy" as an English-language journal of the Korean Society of Gastrointestinal Endoscopy in 2011, it has published several articles on disinfection of the endoscope and its accessories. Many Science Citation Index journals have also emphasized high-level disinfection of the gastrointestinal endoscope. Many papers have been produced specifically, since the outbreak of carbapenem-resistant Enterobacteriaceae in 2013. The recent review papers concluded that quality control is the most important issue among all the aspects of procedural care, including the efficiency of the gastrointestinal endoscopy unit and reprocessing room. Thorough reprocessing of endoscopes using high-level disinfection and sterilization methods may be essential for reducing the risk of infection.

Abstract
AIM: To elucidate the effects of dexamethasone on hypoxia-induced epithelial-to-mesenchymal transition (EMT) in colon cancer.
METHODS: Human colon cancer HCT116 and HT29 cells were exposed to normoxic (21%) and hypoxic (1%) conditions. First, the effect of dexamethasone on cell viability was examined by MTT cell proliferation assay. In order to measure the expression levels of EMT markers (Snail, Slug, Twist, E-cadherin, and integrin αVβ6) and hypoxia-related genes [Hypoxia-inducible factor-1α (HIF-1α) and vascular endothelial growth factor (VEGF)] by dexamethasone, quantitative real-time polymerase chain reaction and western blot analysis were performed. Furthermore, the morphological changes of colon cancer cells and the expression pattern of E-cadherin by dexamethasone were detected through immunocytochemistry. Finally, the effects of dexamethasone on the invasiveness and migration of colon cancer cells were elucidated using matrigel invasion, migration, and wound healing migration assays.
RESULTS: Under hypoxia, dexamethasone treatment inhibited HIF-1α protein level and its downstream gene, VEGF mRNA level in the colon cancer cell lines, HCT116 and HT29. In addition, the presence of dexamethasone down-regulated the mRNA levels of hypoxia-induced Snail, Slug, and Twist, all transcriptional factors of EMT, as well as hypoxia-induced integrin αVβ6 protein level, a well-known EMT marker for colon cancer cells. Furthermore, reduced E-cadherin in hypoxic condition was found to be recoverable by treating with dexamethasone in both colon cancer cell lines. Similarly, under hypoxic conditions, dexamethasone restored the growth pattern and morphological phenotype reminiscent of colon cancer cells grown under normoxic conditions; dexamethasone blocked the migration and invasion of both colorectal cancer cell lines in hypoxia.
CONCLUSION: Our study suggested that dexamethasone has inhibitory effects on cell migration and invasion by suppressing EMT of colon cancer cell lines in hypoxic condition.
