    [Show abstract] [Hide abstract] ABSTRACT: Background The <80 % Helicobacter pylori eradication rate with sequential therapy is unsatisfactory. Modified bismuth quadruple therapy, replacing metronidazole with amoxicillin, could be promising because H. pylori resistance to tetracycline or to amoxicillin is relatively low. A 14-day modified bismuth quadruple protocol as first-line H. pylori treatment was compared with 10-day sequential therapy. Methods In total, 390 H. pylori-infected subjects participated in the randomized clinical trial: 10-day sequential therapy (40 mg pantoprazole plus 1 g amoxicillin twice a day for 5 days, then 40 mg pantoprazole and 500 mg clarithromycin twice a day and 500 mg metronidazole three times a day for 5 days) or 14-day modified bismuth quadruple therapy (40 mg pantoprazole, 600 mg bismuth subcitrate, 1 g tetracycline, and 1 g amoxicillin, twice a day). 13C-urea breath test, rapid urease testing, or histology was performed to check for eradication. Results Intention-to-treat (ITT) eradication rates of 10-day sequential and 14-day quadruple therapy were 74.6 % and 68.7 %, respectively, and the per-protocol (PP) rates were 84.2 and 76.5 %, respectively. The eradication rate was higher in the sequential therapy group, but neither the ITT nor the PP analyses had a significant difference (P = 0.240 and P = 0.099, respectively). However, the adverse events were significantly lower in the modified bismuth quadruple therapy group than the sequential therapy group (36.9 vs. 47.7 %, P = 0.040). Conclusions Ten-day sequential therapy appears to be more effective despite frequent adverse events. However, both 10-day SQT and 14-day PBAT did not reach the excellent eradication rates that exceed 90 %. Additional trials are needed to identify a more satisfactory first-line eradication therapy.

  • [Show abstract] [Hide abstract] ABSTRACT: Background/aims: The resistance rate of Helicobacter pylori is gradually increasing. We aimed to evaluate the efficacy of levofloxacin-based third-line H. pylori eradication in peptic ulcer disease. Methods: Between 2002 and 2014, 110 patients in 14 medical centers received levofloxacin-based third-line H. pylori eradication therapy for peptic ulcer disease. Of these, 88 were included in the study; 21 were excluded because of lack of follow-up and one was excluded for poor compliance. Their eradication rates, treatment regimens and durations, and types of peptic ulcers were analyzed. Results: The overall eradiation rate was 71.6%. The adherence rate was 80.0%. All except one received a protonpump inhibitor, amoxicillin, and levofloxacin. One received a proton-pump inhibitor, amoxicillin, levofloxacin, and clarithromycin, and the eradication was successful. Thirty-one were administered the therapy for 7 days, 25 for 10 days, and 32 for 14 days. No significant differences were observed in the eradication rates between the three groups (7-days, 80.6% vs 10-days, 64.0% vs 14-days, 68.8%, p=0.353). Additionally, no differences were found in the eradiation rates according to the type of peptic ulcer (gastric ulcer, 73.2% vs duodenal/gastroduodenal ulcer, 68.8%, p=0.655). Conclusions: Levofloxacin-based third-line H. pylori eradication showed efficacy similar to that of previously reported first/second-line therapies.

    [Show abstract] [Hide abstract] ABSTRACT: Objective: Adequate tissue acquisition for immunohistochemical (IHC) analysis is important in the differential diagnosis of subepithelial tumors (SETs). We compared the diagnostic yield from IHC analysis between endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) and EUS-guided fine needle biopsy (EUS-FNB) after on-site cytologic evaluation for cellularity in gastric SETs. Methods: In 22 patients with gastric SET, EUS-guided tissue sampling was performed on the same of SETs in a randomized sequence with EUS-FNA followed by EUS-FNB, or vice versa. After on-site cytologic evaluation for cellularity, the cytology and histology were analyzed. Results: There was a significant difference in the median number of needle passes necessary to obtain adequate cellularity in the on-site cytologic evaluation (2.0 in EUS-FNA vs. 1.0 in EUS-FNB, p = 0.008). The proportion of adequate cellularity on the first pass was significantly greater in the FNB than in the FNA group (68.2% vs. 31.8%, p = 0.034). However, diagnosis by histologic analysis with IHC staining was established in 15 (68.2%) and 18 (81.8%) cases by EUS-FNA and EUS-FNB, respectively (p = 0.488). Conclusion: EUS-FNB could decrease the number of needle passes necessary to obtain adequate cellularity and yield a greater proportion of adequate cellularity on the first pass compared to EUS-FNA in gastric SET. However, there was no significant difference in diagnostic yield with IHC staining between two procedures after on-site cytologic evaluation for adequate cellularity.

    [Show abstract] [Hide abstract] ABSTRACT: Background/aims: To investigate the effects of esomeprazole and rebamipide combination therapy on symptomatic improvement in patients with reflux esophagitis. Methods: A total of 501 patients with reflux esophagitis were randomized into one of the following two treatment regimens 40 mg esomeprazole plus 300 mg rebamipide daily (combination therapy group) or 40 mg esomeprazole daily (monotherapy group). We used a symptom questionnaire that evaluated heartburn, acid regurgitation, and four upper gastrointestinal symptoms. The primary efficacy end point was the mean decrease in the total symptom score. Results: The mean decreases in the total symptom score at 4 weeks were estimated to be -18.1±13.8 in the combination therapy group and -15.1±11.9 in the monotherapy group (p=0.011). Changes in reflux symptoms from baseline after 4 weeks of treatment were -8.4±6.6 in the combination therapy group and -6.8±5.9 in the monotherapy group (p=0.009). Conclusions: Over a 4-week treatment course, esomeprazole and rebamipide combination therapy was more effective in decreasing the symptoms of reflux esophagitis than esomeprazole monotherapy.

    [Show abstract] [Hide abstract] ABSTRACT: To describe the features and clinical implications of computed tomography (CT), positron emission tomography (PET), and percutaneous needle aspiration biopsy (PCNB) in pulmonary nontuberculous mycobacterial (NTM) disease manifesting as a solitary nodule, mass, or mass-like consolidation mimicking malignancy. Among a cohort of 388 patients with NTM pulmonary disease, 14 patients with clinically and radiologically suspected lung cancer were included in our study. Two chest radiologists evaluated CT features, including lesion type (nodule, mass, or mass-like consolidation), morphologic features (margin, degree of enhancement, calcification), and presence of accompanying findings suggestive of NTM pulmonary disease (bronchiectasis with clustered centrilobular nodules or upper-lobe cavitary lesions) by consensus. Diagnostic procedures for microbiologic diagnosis of NTM disease and clinical outcome were reviewed. Incidence of NTM pulmonary disease presenting as solitary nodule/mass (n = 8) or mass-like consolidation (n = 6) was 3.6% (14 of 388). Most lesions were detected incidentally during routine health check-up or evaluation of other disease (11 of 14, 79%). Lesions typically showed poor contrast-enhancement (9 of 12) and internal calcification (6 of 14). No lesions had CT features suggestive of NTM pulmonary disease. All 4 lesions for which PET/CT imaging was performed showed strong fluorodeoxyglucose uptake simulating malignant lesions (mean, 4.9; range, 3.6–7.8). PCNB revealed mycobacterial histology in 6 of 11 specimens and positive culture results were obtained for 7 of 7 specimens. NTM pulmonary disease may present as a solitary nodule, mass, or mass-like consolidation mimicking malignancy. CT features and PCNB are important to diagnose NTM disease mimicking lung cancer to avoid unnecessary surgery.

The aim of this study was to evaluate the efficacy of Albis (Daewoong Pharmaceutical Co., Ltd.) for the prevention of gastric mucosal injury caused by aspirin. Methods: Aspirin users were enrolled and randomized into the Albis or placebo group. Screening and follow-up endoscopy were performed for modified Lanza scores (MLSs). Primary outcome was measured by the incidence rate of peptic ulcer, and secondary outcomes were measured by the incidence rate of gastritis, improvement in MLS and subjective symptoms. Results: In total, 81 aspirin users were randomized, 43 in the Albis group and 38 in the placebo group. There was no incidence of peptic ulcer in both groups. The incidence of gastritis was significantly higher in the placebo group (44.4% vs. 10.0%, p=0.003); however, the scores of mucosal edema, hyperemia and hemorrhage were not statistically different between the two groups (p>0.05). The frequency of subjective symptoms were more improved in the Albis group than in the placebo group (p=0.023). Conclusions: The incidence of gastritis was lower in the group that received low-dose aspirin and Albis. The development of peptic ulcer due to long-term use of aspirin might be prevented with concomitant use of Albis.

  • [Show abstract] [Hide abstract] ABSTRACT: Background: The resistance of Helicobacter pylori to antibiotics has increased the need for new empirical, first-line treatments. However, the efficacy of sequential therapy (ST) and concomitant therapy (CT) compared with triple therapy (TT) has not been adequately evaluated. Aim: In this study, we evaluated the efficacy of these empirical three regimens. Methods: The 517 patients enrolled in the study were prospectively randomized to receive 10 days of TT (n =171), ST (n =170), and CT (n =176) at 5 university-affiliated hospitals from May 2013 to March 2015. The post-treatment H. pylori status was determined using the 13C-urea breath test. Results: The baseline characteristics were similar among the three groups. The intention-to-treat eradication rates were 62.6%, 70.6%, and 77.8% in the TT, ST, and CT groups, respectively (p <. 0.01). The corresponding per-protocol eradication rates were 82.8%, 89.5%, and 94.4%, respectively (p <. 0.01). There were no significant differences in the compliance, side effects, and follow-up loss rates. Conclusion: A higher eradication rate was achieved with empirical 10-day ST, and CT than with the TT regimen, with similar rates of compliance and treatment side effects.

    [Show abstract] [Hide abstract] ABSTRACT: Background/aims: Eradication of Helicobacter pylori infection with standard triple therapy (TT) has declined primarily because of increased antibiotic resistance. Sequential therapy (ST) has been suggested as an alternative to TT for the first-line treatment of H. pylori. The purpose of this study was to compare the efficacy of ST with TT. Methods: This was a multicenter, randomized open-label trial performed at nine centers in Korea. Patients with H. pylori infection were randomly assigned to receive either 7 day TT or 10 day ST. Eradication rates, drug compliance, and adverse events were compared among the two regimens. Results: A total of 601 patients were enrolled between March 2011 and September 2014. The intention-to-treat eradication rates were 70.8% for TT and 82.4% for ST (p=0.001). The corresponding per protocol eradication rates were 76.9% and 88.8% for TT and ST, respectively (p=0.000). There were no statistically significant differences between the two regimens with respect to drug compliance and adverse events. Conclusions: ST achieved better eradication rates than TT as a first-line therapy for H. pylori eradication in Korea.

    [Show abstract] [Hide abstract] ABSTRACT: Background/aims: The purpose of this study is to investigate the recurrence rate of peptic ulcer disease (PUD) over a long follow-up period with PUD patients without Helicobacter pylori. Methods: We retrospectively reviewed patients diagnosed with PUD on endoscopy and divided them into two groups a H. pylori-negative group (HP-negative group), and a group of patients with untreated H. pylori (HP noneradicated group). We compared the recurrence rates of PUD in these two groups and analyzed the factors that affected ulcer recurrence. Results: Total of nine hospitals in Korea participated, and a total of 1,761 patients were retrospectively reviewed. The HP-negative group included 553 patients, and the HP noneradicated group included 372 patients. The 5-year cumulative probabilities of PUD recurrence were 36.4% in the HP-negative group and 43.8% in the HP noneradicated group (p=0.113). The factors that were found to affect recurrence in the HP-negative group were elder, male, and comorbid chronic kidney disease. Conclusions: The 5-year cumulative probability of PUD recurrence without H. pylori infection after a long-term follow-up was 36.4% and the factors that affected recurrence were elder, male, and comorbid chronic kidney disease.

    [Show abstract] [Hide abstract] ABSTRACT: Objective: The aim of this bibliometric study was to assess the characteristics and quality of radiologic randomized controlled trials (RCTs) over the past 20 years. Materials and methods: A PubMed search was conducted to identify radiologic RCTs (defined as RCTs in which the first author or corresponding author is affiliated with a radiology department) published between 1995 and 2014. The following information was extracted from each article: journal, radiologic subspecialty, imaging technique, number of subjects, study result, funding, number of authors, number of institutions, country of origin, and methodologic quality (assessed using the Jadad scale). Results: A total of 358 radiologic RCTs were published between 1995 and 2014. Dramatic increases in the numbers of radiologic RCTs were found, from 43 conducted in 1995-1999 to 172 conducted in 2010-2014. One-hundred seventeen (32.7%) RCTs were concerned with the field of vascular and interventional radiology; 78 (21.8%) evaluated more than one imaging technique; 164 (45.8%) had a sample size of 50-150 subjects; 246 (68.7%) showed positive study results; 185 (51.7%) were not funded; 179 (50.0%) had four to seven authors; 263 (73.5%) were single-center trials; 88 (24.6%) had a first author or corresponding author located in the United States; and 187 (52.2%) were of low quality. In the time trend analysis, the following variables showed a significantly positive trend: abdominal imaging subspecialty, CT as the imaging technique, more than 150 subjects, more than seven authors, and high methodologic quality. Conclusion: The quantity and quality of radiologic RCTs have significantly increased over the past 2 decades; however, the methodologic quality remains suboptimal.

    [Show abstract] [Hide abstract] ABSTRACT: Objectives: To correlate imaging features of resected lung adenocarcinoma with epidermal growth factor receptor (EGFR) mutation and the IASLC/ATS/ERS classification histological subtypes. Methods: In 250 consecutive patients with resected lung adenocarcinoma, EGFR mutation status was correlated with demographics, imaging features including ground-glass opacity (GGO) proportion and the IASLC/ATS/ERS classification histological subtypes. Results: EGFR mutations were significantly more frequent in women (54.5 % vs. 38.1 %, p = 0.011) and in never-smokers (54.7 % vs. 35.3 %, p = 0.003). GGO proportion was significantly higher in tumours with EGFR mutation than in those without (30.3 ± 33.8 % vs. 19.0 ± 29.3 %, p = 0.005). EGFR mutation was significantly more frequent in tumours with GGO ≥ 50 % and tumours with any GGO (p = 0.026 and 0.008, respectively). Adenocarcinomas with exon 19 or 21 mutation showed significantly higher GGO proportion than that in EGFR wild-type tumours (p = 0.009 and 0.029, respectively). Absence of GGO was an independent predictor of negative EGFR mutation (odds ratio, 1.81; 95 % confidence interval, 1.16-3.04; p = 0.018). Conclusions: GGO proportion in adenocarcinomas with EGFR mutation was significantly higher than that in EGFR wild-type tumours, and the absence of GGO on CT was an independent predictor of negative EGFR mutation. Key points: • Ground-glass opacity (GGO) proportion is significantly higher in EGFR-mutated adenocarcinomas • Exon 19 or 21 mutated adenocarcinomas shows significantly higher GGO proportion • GGO absence is an independent predictor of negative EGFR mutation in lung adenocarcinomas.

    [Show abstract] [Hide abstract] ABSTRACT: While endoscopic submucosal dissection (ESD) is widely used to treat gastrointestinal tumors, it is rarely used for subepithelial tumors (SETs) originating from the muscularis propria of the esophagus and gastric cardia because of the risk of perforation and problems with inadequate space and field of view during procedures. Submucosal tunneling endoscopic resection (STER) is a new therapeutic method for treating SETs in specific locations in the esophagus and stomach. This technique is highly skill-dependent, using a mucosal flap that covers a deeper part of the gut wall, but is safe and minimally invasive compared with conventional endoscopic approaches such as ESD in SETs originating from the muscularis propria.We report a patient who underwent STER to remove a SET located at the gastric cardia. The patient recovered without any complications. We believe that our case shows the efficacy and safety of the STER technique for patients with a SET originating from the muscularis propria.

    [Show abstract] [Hide abstract] ABSTRACT: Background/aims: We conducted the present study to investigate the recovery of peristalsis of the esophageal body and evaluate the pressure changes observed on manometry before and after endoscopic intervention. Materials and methods: Forty-five patients were diagnosed with achalasia, and 36 received endoscopic or surgical treatment. We collected the data of 24 patients who underwent manometry before and after treatment (pneumatic balloon dilatation, n=7; botulinum toxin injection, n=10; peroral endoscopic myotomy, n=7). Results: The lower esophageal sphincter (LES) resting pressure and nadir LES relaxation pressure decreased regardless of the achalasia subtype or type of endoscopic intervention following treatment (p<0.05). Among patients with a nadir LES relaxation pressure of <4 mmHg, 42.9% (6/14) exhibited partial esophageal peristaltic wave recovery. However, no patients with a nadir LES relaxation pressure of >4 mmHg exhibited peristaltic wave recovery (p=0.024). Of the six patients with peristaltic wave recovery, two had type I achalasia (15.4%), three had type II (33.3%), and one had type III (100.0%). The Eckardt score, symptom duration, and type of intervention were not associated with the recovery of peristaltic waves. Conclusion: Our results suggest that normalization of the nadir LES relaxation pressure can be a predictive factor for the recovery of esophageal peristalsis.

  • [Show abstract] [Hide abstract] ABSTRACT: Immunoglobulin G4 (IgG4)-related disease is characterized by the typical histopathological features of a dense lymphoplasmacytic infiltrate rich in IgG4-positive plasma cells, a high ratio of IgG4- to IgGpositive cells, storiform fibrosis (cellular fibrosis organized in an irregular whorled pattern), obliterative phlebitis, and variable presence of eosinophils. The disease exhibits systemic involvement but very rarely involves the esophagus. A 33-year-old man was admitted to our hospital for evaluation of a 1-year history of progressive dysphagia. Neck imaging revealed a 3.9-cm mass in the cervical esophagus and multifocal calcified lymph nodes in the lower neck and mediastinum. Two previous tertiary hospitals failed to diagnose the patient's condition despite the use of ultrasoundguided needle biopsy of the neck tumor. We performed neck imaging studies, a flexible endoscopic swallowing study, high-resolution manometry, upper endoscopy, and a review of the previous pathologic slides. The patient was finally diagnosed with IgG4-related esophagitis and showed a good response to corticosteroid therapy. We herein report a rare case of dysphagia associated with IgG4-related disease and present a review of the literature.

    [Show abstract] [Hide abstract] ABSTRACT: Background/aims: Pneumoperitoneum is recognized as a benign and self-limiting finding after the insertion of a percutaneous endoscopic gastrostomy (PEG) tube, while complicated pneumoperitoneum is rarely reported. The aim of this study was to reappraise pneumoperitoneum following PEG. Methods: We retrospectively reviewed 193 patients who underwent PEG from May 2008 to May 2014. All patients had a follow-up upright chest or simple abdominal radiograph after PEG. Pneumoperitoneum was quantified by measuring the height of the air column under the diaphragm and graded as small (<2 cm), moderate (2-4 cm), or large (>4 cm). Clinically significant signs were defined as fever, abdominal tenderness or leukocytosis occurring after PEG insertion. Results: Of the 193 study patients, 9 (4.6%) had a pneumoperitoneum visualized by radiographic imaging, graded as small in 5 patients, moderate in 2 patients and large in 2 patients. Clinically significant signs were observed in 5 (55.5%) patients with fever reported in 4 patients, abdominal tenderness in 4 patients and leukocytosis in 4 patients. The time to resolution of free air was 2-18 days. Two patients (22.2%) with moderate or large pneumoperitoneum after PEG died from either pneumonia or septic shock. Conclusions: The clinical course of pneumoperitoneum after PEG is not always benign and self-limiting. These findings suggest that clinicians should not neglect a moderate or large pneumoperitoneum, particularly in patients who have an altered mental status or received antibiotics, since peritoneal irritation cannot be observed under these circumstances.

  • [Show abstract] [Hide abstract] ABSTRACT: Background The efficacy of proton-pump inhibitor–amoxicillin–clarithromycin therapy for H. pylori eradication has decreased over time.Objective We assessed the trend of H. pylori eradication rates over the last 10 years and the relationship between the eradication rates and the amount of macrolide antibiotic use in a country with a high prevalence of H. pylori infection.Methods This vast nationwide multicenter study was conducted with 34,139 adults treated for H. pylori infection from January 2001 to December 2010. The defined daily dose per km2 (DSD) of macrolide antibiotics was calculated (n = 141,019) using the Health Insurance Review & Assessment data base from 2008 to 2010 in the two cities which had the lowest (Jeju city) or highest (Chuncheon city) eradication rate.ResultsThe eradication rates of proton-pump inhibitor–amoxicillin–clarithromycin therapy ranged 84.9–87.5% from 2001 to 2007, and those of 2008 to 2010 ranged 80.0–81.4% with a decreasing trend (p < 0.0001). The decreasing trend of eradication rates for the overall first-line therapy was observed only in three of the seven geographic areas in Korea (p < 0.0001). The DSD of macrolide antibiotics was significantly higher in Jeju than Cheunchon city (0.85 vs 0.52, p < 0.0001).ConclusionsH. pylori eradication rates with clarithromycin-containing triple therapy in Korea showed a decreasing trend over the past 10 years, although the trend varied among geographic areas. This difference may be associated with the amount of macrolide antibiotic use.

  • [Show abstract] [Hide abstract] ABSTRACT: Background and aims: A previous study reported that cold snare polypectomy (CSP) was superior to cold forcep polypectomy (CFP) for the removal of diminutive colorectal polyps (DCPs, ≤5 mm) when assessed for completeness of resection. However, completeness is expected to be greater with CFP when strict investigation of the remnant polyp is performed. The aim of this study was to assess the efficacy of CFP with narrow-band imaging (NBI) evaluation of polypectomy site in removal of DCPs compare with CSP. Methods: This was a randomized, controlled, noninferiority trial at a tertiary referral hospital. Of the 380 patients screened, 146 patients with 231 DCPs were enrolled. CFP was used to resect DCPs until no remnant polyp was visible by NBI endoscopy. The primary noninferiority endpoint was histological eradication of polyps, with a noninferiority margin of -10%. Results: A size of >3 mm was seen in 129 (55.8%) polyps. The overall rates of histological eradication were 90.5% in the CFP group and 93.0% in the CSP group (difference, 2.5%; 95% CI, -9.67 to 4.62). However, when confined to the polyps >3 mm, histological eradication rate was 86.8% and 93.4% (95% CI, -17.2 to 3.6), respectively. Polyp size, histology, location, and the time taken for polypectomy did not differ between the groups. The failure rate of tissue retrieval was higher in the CSP than CFP group (7.8% vs. 0.0%, respectively; P =.001). Conclusions: In this study, more than 90% of all DCPs were completely resected using CFP with NBI evaluation of polypectomy site, showing noninferiority compared with CSP. However, in polyps measuring >3 mm, CFP failed to show noninferiority versus CSP. CFP appears to be proper method for the resection of DCPs 1 to 3 mm in size if no remnant polyp is visible by NBI endoscopy, but is likely insufficient for larger polyps, number: NCT02201147.).
