[Show abstract][Hide abstract] ABSTRACT: Objective:
The effectiveness of Helicobacter pylori therapies has declined with an increase in antibiotic resistance. To overcome this problem, the efficacy of tailored H. pylori eradication therapy based on antimicrobial susceptibility testing was compared with that of empirical second-line rescue regimens.
Material and methods:
Patients who had persistent H. pylori infection after the first eradication were recommended to undergo culture for determining the minimal inhibitory concentration (MIC) via gastroscopy, which increased the cost by 300%. Fourteen-day esomeprazole, tripotassium dicitrate bismuthate, metronidazole and tetracycline (EBMT) therapy or esomeprazole, moxifloxacin and amoxicillin (MEA) therapy was performed according to the results of antibiotic susceptibility testing. In case of refusal to undergo culture, the participants were treated with either 14-day empirical EBMT or MEA regimen for second eradication after explaining the complexity, side effects and costs associated with each regimen. This trial was registered at ClinicalTrials.Gov (NCT 02349685).
In the 219 patients included, the intention to treat (ITT) and per protocol (PP) eradication rates was 75.3% and 79.8% in the 14-day EBMT group (n=89), 70.8% and 72.4% in the 14-day MEA group (n=89) and 87.8% and 100.0% in the 14-day tailored therapy group (n=41), respectively. Based on the PP analysis, the 14-day tailored therapy group showed a significantly higher eradication rate than the 14-day EBMT or MEA group (both p ≤ 0.001).
Tailored therapy based on H. pylori culture and MIC test could be an option as a second-line eradication regimen in the presence of high level of antimicrobial resistance.

[Show abstract][Hide abstract] ABSTRACT: Controversy exists regarding the characteristics of Helicobacter pylori infection-negative gastric cancer (HPIN-GC). The aim of this study was to evaluate clinicopathologic features of HPIN-GC compared to H. pylori infection-positive gastric cancer (HPIP-GC) using a comprehensive analysis that included genetic and environmental factors.
H. pylori infection status of 705 resectable gastric cancer patients was determined by the rapid urease test, testing for anti-H. pylori antibodies, histologic analysis and culture of gastric cancer tissue samples, and history of H. pylori eradication. HPIN-GC was defined as gastric cancer that was negative for H. pylori infection based on all five methods and that had no evidence of atrophy in histology or serology.
The prevalence of HPIN-GC was 4% (28/705). No significant differences with respect to age, sex, smoking, drinking, family history of gastric cancer or obesity were observed between the two groups. HPIN-GC tumors were marginally more likely to involve the cardia (14.3% for HPIN-GC vs 5.3% for HPIP-GC, p=0.068). The Lauren classification, histology, and TNM stage did not differ according to H. pylori infection status. Microsatellite instability was not different between the two groups, but p53 overexpression in HPIN-GC was marginally higher than in HPIP-GC (56.0% for HPIN-GC vs 37.0% for HPIP-GC, p=0.055).
The prevalence of HPIN-GC was extremely low, and its clinicopathologic characteristics were similar to HPIP-GC.
[Show abstract][Hide abstract] ABSTRACT: Background
The 13C-urea breath test (13C-UBT) is a noninvasive method for diagnosing Helicobacter pylori (H. pylori) infection. The aims of this study were to evaluate the diagnostic validity of the 13C-UBT cutoff value and to identify influencing clinical factors responsible for aberrant results.Methods13C-UBT (UBiTkit; Otsuka Pharmaceutical, cutoff value: 2.5‰) results in the range 2.0‰ to 10.0‰ after H. pylori eradication therapy were compared with the results of endoscopic biopsy results of the antrum and body. Factors considered to affect test results adversely were analyzed.ResultsAmong patients with a positive 13C-UBT result (2.5‰ to 10.0‰, n = 223) or a negative 13C-UBT result (2.0‰ to < 2.5‰, n = 66) after H. pylori eradication, 73 patients (34.0%) were false positive, and one (1.5%) was false negative as determined by endoscopic biopsy. The sensitivity, specificity, false-positive rate, and false-negative rate for a cutoff value of 2.5‰ were 99.3%, 47.1%, 52.9%, and 0.7%, respectively, and positive and negative predictive values of the 13C-UBT were 67.3% and 98.5%, respectively. Multivariate analysis showed that a history of two or more previous H. pylori eradication therapies (OR = 2.455, 95%CI = 1.299–4.641) and moderate to severe gastric intestinal metaplasia (OR = 3.359, 95%CI = 1.572–7.178) were associated with a false-positive 13C-UBT result.Conclusion
The 13C-UBT cutoff value currently used has poor specificity for confirming H. pylori status after eradication, and this lack of specificity is exacerbated in patients that have undergone multiple prior eradication therapies and in patients with moderate to severe gastric intestinal metaplasia. In addition, the citric-free 13C-UBT would increase a false-positive 13C-UBT result.
[Show abstract][Hide abstract] ABSTRACT: The average life expectancy of human immunodeficiency virus (HIV)-infected patients has improved dramatically following the advent of highly active anti-retroviral therapy. However, this increased life expectancy has led to a greater incidence of non-acquired immune deficiency syndrome related diseases, including cardiovascular diseases and other malignancies. Increased bone fragility is also a significant concern, with the incidence of osteoporosis and osteoporotic fractures 3- and 2-times more likely, respectively, among HIV-infected patients. Bone mineral density screenings for osteoporosis will therefore become more important as the HIV-infected population ages. Here, we describe six cases of osteoporotic fractures in HIV-infected patients in Korea.
[Show abstract][Hide abstract] ABSTRACT: This study was conducted to evaluate the diagnostic validity of the (13)C-urea breath test ((13)C-UBT) in the remnant stomach after partial gastrectomy for gastric cancer.
The (13)C-UBT results after Helicobacter pylori eradication therapy was compared with the results of endoscopic biopsy-based methods in the patients who have received partial gastrectomy for the gastric cancer.
Among the gastrectomized patients who showed the positive (13)C-UBT results (≥ 2.5‰, n = 47) and negative (13)C-UBT results (< 2.5‰, n = 114) after H. pylori eradication, 26 patients (16.1%) and 4 patients (2.5%) were found to show false positive and false negative results based on biopsy-based methods, respectively. The sensitivity, specificity, false positive rate, and false negative rate for the cut-off value of 2.5‰ were 84.0%, 80.9%, 19.1%, and 16.0%, respectively. The positive and negative predictive values were 44.7% and 96.5%, respectively. In the multivariate analysis, two or more H. pylori eradication therapies (odds ratio = 3.248, 95% confidence interval= 1.088-9.695, P = 0.035) was associated with a false positive result of the (13)C-UBT.
After partial gastrectomy, a discordant result was shown in the positive (13)C-UBT results compared to the endoscopic biopsy methods for confirming the H. pylori status after eradication. Additional endoscopic biopsy-based H. pylori tests would be helpful to avoid unnecessary treatment for H. pylori eradication in these cases.
[Show abstract][Hide abstract] ABSTRACT: Recently, the incidence of pulmonary cryptococcosis is gradually increasing in rheumatoid arthritis (RA) patients. Pulmonary rheumatoid nodules (PRN) are rare manifestations of RA. Eighteen months ago, a 65-year old woman was admitted to hospital due to multiple nodules (2.5×2.1×2 cm) with cavitations in the right lower lobe. She was diagnosed with RA three year ago. She had been taking methotrexate, leflunomide, and triamcinolone. A video-assisted thoracoscopic surgery biopsy was performed and PRN was diagnosed. However, a newly growing huge opacity with cavitation was detected in the same site. Pulmonary cryptococcal infection was diagnosed through a transthoracic computed tomograpy guided needle biopsy. Cryptococcus antigen was detected in serum but not in cerebrospinal fluid. The patient was treated with oral fluconazole which resulted clinical improvement and regression of the nodule on a series of radiography. Herein, we report the case of pulmonary cryptococcosis occurring in the same location as that of the PRN.

[Show abstract][Hide abstract] ABSTRACT: Background and AimsResistance rates of H. pylori to clarithromycin, metronidazole and quinolone are over 30% in S. Korea. Aim of this prospective study was to evaluate the ultimate eradication rate of H. pylori after 1st, 2nd or 3rd line therapy in Korea.MethodsA cohort of 2,202 patients with H. pylori was treated with proton pump inhibitor (PPI)-based triple therapy for 7 days. In case of treatment failure or recurrence, moxifloxacin-based triple therapy (MA) or bismuth-based quadruple therapy (QUAD) was randomly given. When the 2nd-line treatment failed or H. pylori recurred, the unused MA or QUAD was used as a third-line treatment.ResultsEighty-six patients had recurrence at least once during consecutive lines of treatments. Among 2,116 patients (intention-to-treat, ITT) without recurrence, 1,644 (77.7%, per-protocol, PP) completely followed our treatment flow. The ITT and PP rates of first line treatment were 69.8% and 89.3%. After second line, they reached 78.4% (ITT) and 98.4% (PP). The ′final′ eradication rate up to 3rd line treatment were 80.0% (1692/2116) and 99.8% (1641/1644), respectively. Resistance to clarithromycin showed significantly lower eradication rate (OR 0.358, P<0.001) than those with susceptible strains in multivariate analysis. However in PP analysis, there was no significant difference in ultimate success rate regarding resistance pattern.Conclusions
Final success rate of PP was high, 99.8% in Korea in spite of high antibiotic resistance rates. However, high rate of refusal of further treatment and follow-up loss made ITT eradication rate low. Proper strategy to improve the treatment adherence is needed.

[Show abstract][Hide abstract] ABSTRACT: Open converted cholecystectomy could occur in patients who planned for laparoscopic cholecystectomy after endoscopic removal of choledocholithiasis. To evaluate the risk factors associated with open converted cholecystectomy. The data for all patients who underwent cholecystectomy after endoscopic removal of choledocholithiasis were retrospectively reviewed. Factors predictive for conversion to open cholecystectomy were analyzed. The rate of open converted cholecystectomy was 15.7 %. In multivariate analysis, cholecystitis (OR 1.908, 95 % CI 1.390-6.388, p = 0.005), mechanical lithotripsy (OR 6.129, 95 % CI 1.867-20.123, p < 0.005), and two or more choledocholithiases (OR 2.202, 95 % CI 1.097-4.420, p = 0.026) revealed significant risk factors for conversion to open cholecystectomy. Analyzing the risk factors for open converted cholecystectomy according to duration from endoscopic stone removal to cholecystectomy (within 2 weeks, between 2 and 6 weeks, and beyond 6 weeks), acute cholangitis (OR 3.374, 95 % CI 1.267-8.988, p = 0.015), cholecystitis (OR 3.127, 95 % CI 1.100-8.894, p = 0.033), and mechanical lithotripsy (OR 17.504, 95 % CI 3.548-86.355, p < 0.005) were related to open converted cholecystectomy in a parts per thousand currency sign2 weeks group. For patients who need cholecystectomy after endoscopic removal of choledocholithiasis, endoscopic retrograde cholangiography-related factors predictive for open converted cholecystectomy are helpful in planning the appropriate timing of surgery.

[Show abstract][Hide abstract] ABSTRACT: Background:
The Helicobacter felis (H. felis) mouse model has been developed for the research regarding pathogenesis of chronic gastritis and gastric cancer. The aim of this study was to investigate long-term H. felis colonization in the stomachs of C57BL/6 mice and subsequent histologic findings and inflammatory reactions including pro-inflammatory cytokines.
Twenty-three female C57BL/6 mice at 4 weeks of age were gavaged with H. felis, and 13 control mice served as vehicle only. The mice were sacrificed at 4, 24, and 52 weeks after inoculation. The infection status and degree of inflammation were determined by culture and histopathology. The level of gastric mucosal myeloperoxidase (MPO), tumor necrosis factor alpha (TNF-α), and interleukin-1beta (IL-1β) were measured by ELISA.
The overall infection rate was 100%, as determined by the culture and histology. At 4, 24, and 52 weeks, the neutrophil and monocyte scores were significantly higher in infected mice than in control mice. At 24 weeks after inoculation, most of the infected mice showed mucosal atrophy with or without metaplasia, and a few showed focal dysplasia. Adenocarcinoma was observed in one mouse at 52 week post-infection. Gastric mucosal MPO and IL-1β levels were significantly higher in infected mice than those in control mice at 24 and 52 weeks. However, the expression of gastric mucosal TNF-α was not significantly different between the infected and control mice at any time-point.
Long-term H. felis-infection in C57BL/6 mice provoked a severe inflammatory reaction and it progressed into atrophy, metaplasia, dysplasia and cancer. IL-1β might play an important role in the inflammatory response of mice to Helicobacter species.

Because of its rarity, there is no consensus on the optimal endoscopic hemostasis technique for rectal DL. We analyzed six patients who underwent endoscopic management for rectal DL after presenting with hematochezia at a single institute over 10 years. Of the six patients, three underwent endoscopic band ligation (EBL) and three underwent endoscopic hemoclip placement (EHP). Only one patient was treated with thermocoagulation. There were no immediate complications in any of the patients. None of the patients required a procedure or surgery for the treatment of rebleeding. Mean procedure times of EBL and EHP were 5.25 minutes and 7 minutes, respectively. Both EHP and EBL are shown to be effective in the treatment of bleeding rectal DL. We suggest that EBL may have potential as the preferred therapy owing to its superiority in technical and economic aspects, especially in elderly and high-risk patients.
[Show abstract][Hide abstract] ABSTRACT: Background and aims:
Gastric atypical cell (GAC), an indefinite pathologic finding, often requires repeated biopsy or other diagnostic treatments, such as endoscopic mucosal resection (EMR), endoscopic submucosal dissection (ESD), or operation (OP). The aim of this study was to analyze the initial endoscopic and histologic findings of GAC and to discuss the necessity of EMR/ESD at establishing a correct diagnosis.
This retrospective study enrolled 96 patients proven as GAC on index forceps biopsy. ESD (17/96, 17.7%), EMR (5/96, 5.2%), OP (20/96, 20.8%), and other treatment or follow-up (54/96, 56.3%) were performed. We analyzed the initial endoscopic and histologic characteristics of GAC lesions, predictive of neoplasm.
After diagnostic modalities, the final pathologic diagnoses were cancer (36/96, 37.6%), dysplasia (9/96, 9.4%), and non-neoplasm (51/96, 53.0%). In univariate analysis, age [odds ratio (OR) 1.04, 95% confidence interval (CI) 1.01-1.07], lesion size of 10 mm or greater (OR 3.94, 95% CI 1.61-9.61), lesion with depressed type (OR 2.50, 95% CI 1.09-5.72), and presence of H. pylori (OR 2.83, 95% CI 1.11-7.25) were risk factors for neoplasm. In multivariate analysis, lesion size of 10 mm or greater (OR 3.63, 95% CI 1.23-10.66), lesion with depressed type (OR 2.86, 95% CI 1.11-7.38) were independent risk factors for cancer.
Considering the neoplastic risk of GAC, which could be missed on biopsy, more comprehensive tissue sampling via EMR/ESD might be necessary to establish a definite diagnosis.

[Show abstract][Hide abstract] ABSTRACT: Introduction:
Resection of rectal neuroendocrine tumors (NETs) less than 1 cm in diameter can be performed using various endoscopic techniques. Endoscopic mucosal resection (EMR) traditionally had suboptimal complete resection rate compared to endoscopic submucosal resection with band ligation (ESMR-L). However, the previous studies did not consider the characteristics of rectal NETs. The aim of our study is to compare the efficacy of ESMR-L and EMR using tailored approach according to the characteristics of rectal NETs.
82 rectal NETs in 77 patients treated by ESMR-L (n = 48) or EMR (n = 34) between September 2007 and October 2012 were retrospectively analyzed. ESMR-L was used for flat-type tumors or tumors with non-lifting sign after submucosal injection. Conventional EMR was used for elevated-type tumors or tumors with well-lifting sign after submucosal injection.
The pathological complete resection rate was higher in the ESMR-L group (45 lesions, 93.8%) compared with the EMR group (30 lesions, 88.2%); however, this difference was not significant (p = 0.441). Overall complication did not differ significantly between the ESMR-L group and the EMR group (p = 0.774). There was one case of a remnant lesion in the ESMR-L group, which was managed by EMR after circumferential pre-cutting (EMR-P), and no recurrence has been detected in either the ESMR-L or EMR group.
ESMR-L and EMR procedures could have a similar excellent complete resection rate, if we select the endoscopic resection technique according to the characteristics of the small rectal NETs.

[Show abstract][Hide abstract] ABSTRACT: Background:
Atrophic gastritis is a precancerous condition, which can be diagnosed by several methods. However, there is no consensus for the standard method. The aim of this study was to evaluate the correlations among endoscopic, histologic, and serologic findings for the diagnosis of atrophic gastritis.
From March 2003 to August 2013, a total of 2,558 subjects were enrolled. Endoscopic atrophic gastritis was graded by Kimura-Takemoto classification and histological atrophic gastritis was assessed by updated Sydney system. Serological assessment of atrophic gastritis was based on serum pepsinogen test.
The serum pepsinogen I/II ratio showed a significant decreasing nature when the extent of atrophy increased (R2=0.837, P<0.001) and the cut-off value for distinguishing between presence and absence of endoscopic atrophic gastritis was 3.2. The serum pepsinogen I and pepsinogen I/II ratio were significantly lower when the histological atrophic gastritis progressed and the cut-off value was 3.0 for a diagnosis of histological atrophic gastritis. A significant correlation between endoscopic and histological atrophic gastritis was noted and the sensitivity and specificity of endoscopic diagnosis were 65.9% and 58.0% for antrum, 71.3% and 53.7% for corpus, respectively.
The endoscopic, histological, and serological atrophic gastritis showed relatively good correlations. However, as these three methods have a limitation, a multifactorial assessment might be needed to ameliorate the diagnostic accuracy of atrophic gastritis.
[Show abstract][Hide abstract] ABSTRACT: Candida is a rare cause of infectious arthritis, and it can be found in infants and immunocompromised patients. Patients with maintenance hemodialysis are prone to opportunistic infections because of altered immunity, and frequent exposures to health-care associated infections. Herein, we report a case of candida arthritis of right shoulder with preceding fungemia in patients with maintenance hemodialysis. The diagnosis is based on the isolation of Candida Tropicalis from blood and synovial fluids of the shoulder joint. The patient has received intravenous fluconazole and arthroscopic surgical debridement. We then changed the fluconazole into amphotericin B due to the abnormal signs in the liver function tests, although the fluconazole successfully controlled fungemia and arthritis. To the best of our knowledge, this is the first case of candida arthritis in patients with maintenance hemodialysis in South Korea.
[Show abstract][Hide abstract] ABSTRACT: To clarify the short and long-term results and to prove the usefulness of endoscopic resection in type 3 gastric neuroendocrine tumors (NETs).
Of the 119 type 3 gastric NETs diagnosed from January 1996 to September 2011, 50 patients treated with endoscopic resection were enrolled in this study. For endoscopic resection, endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) was used. Therapeutic efficacy, complications, and follow-up results were evaluated retrospectively.
EMR was performed in 41 cases and ESD in 9 cases. Pathologically complete resection was performed in 40 cases (80.0%) and incomplete resection specimens were observed in 10 cases (7 vs 3 patients in the EMR vs ESD group, P = 0.249). Upon analysis of the incomplete resection group, lateral or vertical margin invasion was found in six cases (14.6%) in the EMR group and in one case in the ESD group (11.1%). Lymphovascular invasions were observed in two cases (22.2%) in the ESD group and in one case (2.4%) in the EMR group (P = 0.080). During the follow-up period (43.73; 13-60 mo), there was no evidence of tumor recurrence in either the pathologically complete resection group or the incomplete resection group. No recurrence was reported during follow-up. In addition, no mortality was reported in either the complete resection group or the incomplete resection group for the duration of the follow-up period.
Less than 2 cm sized confined submucosal layer type 3 gastric NET with no evidence of lymphovascular invasion, endoscopic treatment could be considered at initial treatment.

[Show abstract][Hide abstract] ABSTRACT: In colonoscopic study, benign colorectal strictures with or without symptomatic pain are not rarely encountered. Benign colorectal stricture can be caused by a number of problems, such as anastomotic stricture after surgery, inflammatory bowel disease, postendoscopic submucosal dissection, diverticular disease, ischemic colitis, and so on. There are various modalities for the management of benign colorectal stricture. Endoscopic balloon dilatation is generally considered as the primary treatment for benign colorectal stricture. In refractory benign colorectal strictures, several treatment sessions of balloon dilatation are needed for successful dilatation. The self-expandable metal stent and many combined techniques are performed at present. However, there is no specific algorithmic modality for refractory benign colorectal strictures.
[Show abstract][Hide abstract] ABSTRACT: Endoscopic submucosal dissection has recently been practiced on a differentiated type of early gastric cancer. However, there is no clear evidence for endoscopic treatments of signet ring cell carcinoma. The aim of this study is to identify the predictive clinicopathological factors for lymph node metastasis in signet ring cell carcinoma for assisting endoscopic submucosal dissection trials.
A total of 186 patients with early signet ring cell carcinoma who underwent radical curative gastrectomy between January 2001 and September 2009 were enrolled in this study. Retrospective reviews of their medical records are being conducted. Several clinicopathologic factors were being investigated in order to identify predictive factors for lymph nodes metastasis: age, gender, tumor size, type of operation, tumor location, gross type, ulceration, Lauren's classification, depth of invasion, and lymphatic invasion.
The lymph node metastasis rate for signet ring cell carcinoma was 4.3% (n=8). Of the 186 lesions with early signet ring cell carcinoma, 91 (48.9%) tumors were larger than 15 mm in size and 40 (21.5%) showed submucosal invasions in the resection specimens. In multivariate analysis, only the lymphatic invasion (P<0.0001) showed an association with lymph node metastasis. To evaluate cutoff values for tumor sizes in the presence of lymph node metastasis, early signet ring cell carcinomas with lymphatic invasions were excluded. In the absence of lymphatic invasion, mucosal cancer with tumor sizes <15 mm had no lymph node metastasis.
Endoscopic submucosal dissection can be performed on patients with early signet ring cell carcinoma limited to the mucosa and less than 15 mm.

[Show abstract][Hide abstract] ABSTRACT: A 2-year-old male mixed dog was referred to us for further evaluation and treatment of a
4-week-history of oliguria and abdominal distension after a surgical repair of urethral
injury. To relieve the urethral stricture, we placed a self-expanding aortic stent graft
extension with a partial coverage with an expanded polytetrafluoroethylene (ePTFE). After
the placement of the stent, the dog presented with a normal urinary voiding, despite the
presence of urinary incontinence. The current case indicates that the ePTFE-covered,
self-expanding ASGE is an effective intervention for the treatment of severe urethral
stricture in the dog.

[Show abstract][Hide abstract] ABSTRACT: The prognosis of an early gastric cancer (EGC) is generally excellent, with a 5-year survival rate of 90% in most reports; however, there have been few reports of EGC with distant metastases. Recently we encountered a rare case of EGC with synchronous multiple bone metastases. A 43-year-old woman visited a local clinic due to back pain. Lumbar spine metastases were suspected by MRI. She was transferred to our hospital and underwent bone marrow biopsy which revealed an adenocarinoma. After endoscopic evaluation for primary cancer work-up, we found a suspicious EGC lesion. The results of endoscopic biopsy was signet ring cell carcinoma. Our pathologist additionally reviewed the bone marrow biopsy slides and found signet ring cells in it. PET CT showed disseminated multiple bone metastases but, there wasn't any other malignant lesion. Here we report a rare case of EGC with synchronous multiple bone metastases.
[Show abstract][Hide abstract] ABSTRACT: ERCP is the most common procedure for the diagnosis and treatment of bile duct and pancreatic disease, but Post-ERCP pancreatitis makes poor outcome in some cases. The protease inhibitors, nafamostat and gabexate, have been used to prevent pancreatitis related to ERCP, but there is some debate. We tried to evaluate the efficacy of gabexate and nafamostat for the prevention of post-ERCP pancreatitis.
Two hundred forty two patients (73 patients in the gabexate group, 88 patients in the nafamostat group and 81 patients in the placebo group) were included in the study after selective exclusion. The incidence of pancreatitis after ERCP was compared among groups.
The incidence of pancreatitis were 6.8% in the gabexate group, 5.7% in the nafamostat group and 6.2% in the placebo group (p=0.954).
There was no meaningful difference among the gabexate, nafamostat and placebo group.
