BACKGROUND/AIMS@#Irsogladine maleate, an enhancer of gastric mucosal protective factors, has demonstrated its efficacy for various gastric mucosal injuries. The aim of this study was to evaluate the efficacy and safety of irsogladine for prevention of nonsteroidal anti-inflammatory drugs (NSAIDs) or aspirin-induced peptic ulcer and gastritis.@*METHODS@#In this multicenter, randomized, double-blind, exploratory clinical trial, 100 patients over 50 years of age who needed continuous NSAIDs or aspirin for more than 8 weeks were randomly assigned to either test group (irsogladine maleate 2 mg, twice daily, 39 patients for full analysis) or placebo group (37 patients for full analysis). Primary outcomes were incidence of peptic ulcer and ratio of modified Lanza score (MLS) 2 to 4. Secondary outcome was the number of acute erosions confirmed by endoscopy at 8 weeks. Adverse effects were also compared.@*RESULTS@#There were no significant differences in gastric protective effects between test and placebo groups. However, two cases of peptic ulcer in the placebo group but none in the test group were observed. These two cases of peptic ulcer were Helicobacter pylori-negative. In addition, H. pylori-negative group showed significant changes in MLS score (p = 0.0247) and edema score (p = 0.0154) after the treatment compared to those before treatment in the test group. There was no significant difference in adverse events between the two groups.@*CONCLUSIONS@#The efficacy of irsogladine maleate was found in H. pylori-negative group, suggesting its potential as a protective agent against NSAIDs or aspirin-induced peptic ulcer and gastritis.
RÉSUMÉ
For patients refusing surgical treatment for deep early gastric cancer, hybrid natural orifice transluminal endoscopic surgery with sentinel lymph node navigation is a potential treatment option, particularly when the anatomic location of the cancer has low probability of lymph node metastasis. We report a case of deep early gastric cancer of the fundus beyond the endoscopic submucosal dissection indication that was treated by hybrid natural orifice transluminal endoscopic surgery with sentinel lymph node navigation. In a conventional approach, a total gastrectomy would have been needed; however, the patient refused surgical intervention. In this case, since the patient showed no positivity of the sentinel lymph node on intraoperative navigation, laparoscopic basin lymph node dissection was not performed. Hybrid natural orifice transluminal endoscopic surgery might be considered for specific regions such as the safety zone where lymph node metastases are less likely to occur.

Osler-Weber-Rendu disease is a rare autosomal dominant disorder of fibrovascular tissues, characterized by a classic triad of mucocutaneous telangiectasias, recurrent hemorrhages, and a familial occurrence. Portosystemic encephalopathy in a patient with Osler-Weber-Rendu disease is rare, but we experienced a case presenting with recurrent portosystemic encephalopathy in Osler-Weber-Rendu disease. We report on a case of a 75-year-old female presenting with an altered mentality. Initial studies including brain imaging study did not reveal any specific cause for her mental status. She was diagnosed with the rare disease after a series of tests and received conservative treatment. Her neurological status recovered fully without complication after conservative treatment and she was discharged after 18 hospital days. This case demonstrated an extremely rare case of Osler-Weber-Rendu disease presenting as portosystemic encephalopathy treated successfully with conservative treatment. For patients who have shown hepatic encephalopathy without a definite cause, we recommend evaluation for the possibility of Osler-Weber-Rendu disease. Conservative treatment based on treatment of advanced liver cirrhosis could be an alternative solution.

BACKGROUND/AIMS: Microscopic colitis is characterized by chronic watery diarrhea with specific pathological changes that can be diagnosed by microscopic examination. We performed immunohistochemical analysis of proinflammatory cytokines to investigate the pathogenic mechanism of microscopic colitis. METHODS: This study consisted of six patients with lymphocytic colitis, six patients with collagenous colitis, and six patients with functional diarrhea but normal pathology. We performed an immunohistochemical analysis of the colonic mucosal biopsies to assess the expression of cyclo-oxygenase-2, interleukin-17, nuclear factor-kappaB, interferon-gamma, inducible nitric oxide synthase, and tumor necrosis factor-alpha. We compared the quantity score of immunohistochemical staining among the groups. RESULTS: The microscopic colitis group showed significantly higher expression of cyclo-oxygenase-2, interleukin-17, nuclear factor-kappaB, and interferon-gamma compared with the control group. Cytokine expression was similar between collagenous colitis and lymphocytic colitis. However, the expression of cyclo-oxygenase-2 was higher in collagenous colitis. CONCLUSIONS: Proinflammatory cytokines, including interleukin-17 and interferon-gamma, are highly expressed in microscopic colitis. The expression of cyclo-oxygenase-2 was higher in collagenous colitis than in lymphocytic colitis. This study is the first on interleukin-17 expression in microscopic colitis patients.

BACKGROUND/AIMS: The relationship between Crohn's disease and gallstones is established. However, the prevalence and risk factors for gallstones in patients with ulcerative colitis (UC) are not yet well understood. The aim of this study was to evaluate the prevalence and risk factors of gallstones in patients with UC. METHODS: This study was a retrospective single center study. A total of 87 patients with UC and 261 healthy controls were enrolled. Age, sex, and body mass index were matched. To investigate risk factors, the extent of UC, duration of disease, number of hospital admissions, and number of steroid treatments in patients with UC were evaluated. RESULTS: The prevalence of gallstones in patients with UC was 13.8%, whereas that in healthy controls was only 3.1% (P or =50 years of age had a 3.6-times higher risk of gallstones compared to that in those <50 years of age, and the difference was statistically significant (odds ratio, 3.60; confidence interval, 1.03-12.61) in univariate analysis. There were no statistically significant disease-related risk factors for gallstones in UC patients. CONCLUSIONS: This is the first study of gallstone prevalence in Korean UC patients. In this study, patients with UC had a higher prevalence of gallstones compared to that in well-matched healthy controls. Age seemed to be a possible risk factor, and more studies are needed. Further prospective, large-scale studies will be required to confirm the risk factors for gallstones in UC patients.

BACKGROUND/AIMS: Age, sex, gene and life style are modulating risks for colon cancer. Although alcohol intake may impact on colorectal adenoma, clear association has not been established yet. We aimed to investigate effects of alcohol consumption on the characteristics of colorectal adenoma. METHODS: Patients who underwent colonoscopic polypectomy of colorectal adenoma in the department of gastroenterology of Eulji hospital through 2005 to 2012, having both blood tests and ultrasound or abdominal CT examination were enrolled. The alcohol drinking patients were subdivided into normal or abnormal laboratory group, and alcoholic liver diseases group. RESULTS: 212 patients with colorectal adenoma were analyzed; advanced adenoma and multiple adenoma were found in 68 (32.0%) and 79 (37.2%) patients. When compared to the nondrinker group (120/212 patients), the alcohol drinker group (92/212 patients) represented significantly high odds ratios (ORs) for advanced adenoma (OR, 2.697; P=0.002), and multiple adenoma (OR, 1.929; P=0.039). Among alcohol drinker (92 patients), the ORs of advanced adenoma were 6.407 (P=0.003) in alcoholic liver diseases group (17 patients), 3.711 (P=0.002) in the alcohol drinker with abnormal lab (24 patients), and 2.184 (P=0.034), in the alcohol drinker with normal lab (51 patients) compared to nondrinker group. CONCLUSIONS: This study showed that alcohol drinking may influence on the development of advanced colorectal adenoma and multiplicity. Especially in the group with alcoholic liver diseases and with abnormal lab presented significantly higher ORs of advanced adenoma.

Crohn's disease (CD) may involve any part of the gastrointestinal tract, from the mouth to the anus. Approximately >90% of cases occur in the small bowel and colon. Upper gastrointestinal involvement, especially duodenal manifestation, is relatively rare. Therefore, adequate medical treatment for duodenal CD has not yet been established. We report a case of CD with duodenal involvement. A 46-year-old man with Crohn's ileocolitis presented to our hospital with right upper quadrant pain. An endoscopy showed a deep excavated ulcer with deformity at the duodenal bulb, and he was initially treated with azathioprine (1 mg/kg), Pentasa (3.0 g/day), and a proton pump inhibitor for 1 year. However, the deep ulcer did not heal. Therefore, infliximab infusion therapy was initiated, and the duodenal lesion completely resolved on follow-up esophagogastroduodenoscopy. We report a case of duodenal CD that completely resolved following infliximab infusion, with a review of the literature.

Amyloidosis is a group of disorders characterized by the extracellular accumulation of insoluble, fibrillar proteins in various organs and tissues. It is classified, on the basis of the identity of the precursor protein, as primary, secondary, or familial amyloidosis. Gastrointestinal amyloidosis usually presents as bleeding, ulceration, malabsorption, protein loss, and diarrhea. However, gastric amyloidosis with gastric outlet obstruction mimicking linitis plastica is rare. We report a case of gastrointestinal amyloidosis with gastric outlet obstruction in a patient with ankylosing spondylitis. The patient was indicated for subtotal gastrectomy because of the aggravation of obstructive symptoms, but refused the operation and was transferred to another hospital. Three months later, the patient died of aspiration pneumonia during medical treatment.

Infliximab is a chimeric IgG1 monoclonal antibody to tumor necrosis factor (TNF)-alpha used in the treatment of steroid refractory or dependent Crohn's disease (CD). Patients with active CD are more likely to experience stillbirth, preterm labor, or small for gestational aged babies. The safety of administering infliximab in pregnant patients is not well documented. A 25-year-old woman, who was diagnosed with small bowel CD three years ago, was admitted to our hospital due to the aggravation of abdominal pain. She had been treated with mesalazine, azathioprine and intermittent steroid for three years. After admission, she did not respond to steroid therapy, we decided to try infliximab. After the administration of infliximab, epigastric pain was relived and Crohn's disease activity index score decreased significantly. However after the fourth infusion of infliximab, the patient became aware that she was ten gestational weeks old pregnancy state After then, infliximab was stopped and maintained by mesalazine. The patient gave birth to a healthy baby via normal vaginal delivery without the recurrence of CD. This case suggests that infliximab administration is safe during the early period of pregnancy. Thus, we report this case with a review of literature.

Gastroesophageal reflux disease (GERD) has a chronicity and its symptoms wax and wane by proton pump inhibitor (PPI) therapy. Chronic consumption of PPI in the patients with GERD is common, and we can cope with a PPI failure or refractory GERD. Therefore, we review various alternative modalities for chronic PPI treatment and an approach for refractory GERD. PPI has a potential for side effects. Many studies have been published the side effects of long-term PPI using. Mostly clinical level of evidence is weak and the absolute risk is low, however we may discuss the patients who need long-term PPI therapy about the controversial side effects, and manage those appropriately.

Colorectal cancer is rare in teenagers, especially without known risk factors. Colon cancer in young age is more likely to be diagnosed at advanced-stage, to present unfavorable tumor histology such as mucinous carcinoma, and poor outcome. We report a case of sporadic mucinous adenocarcinoma of the colon in a 19-year-old male patient without any risk factors. He complained of severe left abdominal pain that developed 1 month ago. He had a distended abdomen with severe tenderness on the left lower quadrant. A distal descending colon mass causing mechanical obstruction was observed on abdominal computed tomography. Emergency colonoscopy showed a large, fungating mass obstructing the lumen at 40 cm from the anal verge. Biopsy of the colonic mass suggested a mucinous adenocarcinoma. After decompression by colonic stent, the patient was transferred to the general surgery department for left hemicolectomy. The lesion was confirmed to be a mucinous adenocarcinoma (7.0x4.5 cm). For hereditary nonpolyposis colorectal cancer evaluation, immunohistochemical staining for MLH1 and MSH2 was normal. Reverse transcription polymerase chain reaction analysis did not detect microinstability in any of the markers tested. The patient had no familial history of cancer. Mucinous adenocarcinoma has high frequencies of poor differentiation, advanced tumor stage, loss of mismatch repair gene expression, and increased MUC2 expression. A mucinous histology is considerably more frequent in children and adolescent than in adults. Adequate invasive study is also necessary for young age patients.

BACKGROUND/AIMS: The meaning of specialized intestinal metaplasia (SIM) in the diagnosis of Barrett's esophagus (BE) is not clear. This study was designed to determine the clinical significance of SIM in the diagnosis of Barrett's esophagus. MATERIALS AND METHODS: Biopsies were taken from 601 subjects with endoscopically suspected columnar-lined esophagus. Under light microscopy with Alcian-blue stain, SIM was identified. Demographic characteristics, gastroesophageal (GE) reflux symptoms and endoscopic findings were compared between the SIM-present group and the SIM-absent group. RESULTS: Among 601 subjects, 184 (30.6%) were confirmed by pathology to have SIM. Age over 40 years (P<0.001) and a medication history of proton pump inhibitor or H2 blocker were found more frequently in the SIM-present group (P=0.01) than in the SIM-absent group. Any of 7 GE reflux symptoms (heartburn, acid regurgitation, chest pain, hoarseness, globus sensation, cough and epigastric soreness) were more frequent in the SIM-present group than SIM-absent group (P<0.001). Specifically, heartburn, chest pain and cough were significantly more common in the SIM-present group. There was no clinically significant difference associated with endoscopic findings or other clinical characteristics. CONCLUSIONS: When subjects with endoscopically suspected BE are analyzed based on the presence or absence of SIM, the SIM-present group was significantly associated with GE reflux symptoms suggestive of frequent GE reflux. However, the presence of SIM did not correlate with endoscopic findings.

BACKGROUND/AIMS: Chronic gastritis is a common finding during endoscopy and it is very important to describe it correctly. This study was designed to evaluate the distribution of endoscopic gastritis and the differences according to age, sex or area. MATERIALS AND METHODS: A clinical analysis was conducted on 25,536 subjects who had undergone an upper endoscopy for routine health check-up. Endoscopic gastritis was classified into four types, superficial gastritis, erosive gastritis, atrophic gastritis and intestinal metaplasia. The distribution of the four types of gastritis was evaluated according to sex, age and area. RESULTS: 51.6% of the patients had experienced at least one of the symptoms (epigastric pain or discomfort, soarness, dyspepsia, abdominal pain) on at least a few occasions during the previous year. The incidence of normal gastric finding was 3,593 (14.1%). 21,943 (85.9%) subjects have at least more than one of endoscopic gastritis. The number of cases with superficial gastritis was 7,983 (31.3%), erosive gastritis 6,054 (23.7%), atrophic gastritis 6,918 (27.1%), and intestinal metaplasia 1,181 (7.1%). Erosive gastritis, atrophic gastritis and intestinal metaplasia were more frequent in men than women (P or =60 years) than younger age group (P<0.001). CONCLUSIONS: The prevalence of endoscopic gastritis was very common, 85.9%. In addition, erosive gastritis, atrophic gastritis and intestinal metaplasia were more frequent in men and in the older age group, which is similar to gastric cancer or peptic ulcer. Cautious regular endoscopic follow-up might be necessary regardless of gastrointestinal symptoms in Korea.

RÉSUMÉ
A bronchogenic cyst is regarded as a developmental abnormality of the primitive foregut, which typically occurs in the mediastinum. The cystis normally diagnosed in relation to respiratory problems or recurrent infections in children. In adulthood, it is a rare pathology, and its diagnosis is usually incidental. Moreover, subdiaphragmatic and retroperitoneal locations are exceptionally rare. A 60-year old woman presented with an incidental left retroperitoneal mass that was suspected of being a non-functioning retroperitoneal tumor. After evaluating the general radiologic and endocrinologic work up for a retroperitoneal tumor, a laparoscopically complete resection was performed with primary repair of the attached diaphragm. The surgically resected cyst measured 7x5x5 cm and was filled with mucin material. Histologically, the cyst wall was lined by a ciliated pseudostratified or tall columnar epithelium without dysplastic changes. The diagnosis of a bronchogenic cyst in the retroperitoneum was confirmed. We present this case with a review of the relevant literature.

Some cases have reported that amebic colitis leads to serious complications that are caused by a misdiagnosis of an inflammatory bowel disease and consequential ill-managed steroid therapy. Therefore, it should be stressed that the differential diagnosis on such a case is very important. Eosinophilic colitis may reveal its presence as diarrhea, abdominal pain, ascites, and eosinophilic deposits in tissues. Therefore, it is highly necessary to make a differential diagnosis to distinguish eosinophilic colitis from other infectious or inflammatory bowel diseases. We report a case of amebic colitis, which was mistakenly diagnosed as eosinophilic colitis and a liver eosinophilic abscess in a young male who complained of bloody diarrhea and right upper quadrant pain. However, the misdiagnosed steroid therapy did not aggravate the progress of the amebic infection.
