ABSTRACT

Background/Aims@#Several clinical factors have been used to predict the response for concurrent chemoradiotherapy (CCRT); however, these factors are insufficient for prognostic predictions. We investigated clinical factors to assess whether they could be used to predict the response to CCRT and the survival of patients with esophageal cancer. @*Methods@#Patients with esophageal cancer underwent CCRT from January 2005 to December 2015. Response to CCRT was classified as progressive disease (PD), stationary disease (SD), partial remission (PR), or complete remission (CR). Factors to predict the response to CCRT and patient survival were subsequently investigated. @*Results@#A total of 535 esophageal cancer patients underwent CCRT. Four hundred ninety-three patients were followed up, and patient outcomes were investigated. In the adjusted analysis, patients with advanced stage disease (relative risk [RR], 0.28 in stage III and 0.12 in stage IV compared to stage I), poor performance status, circumferential involvement (RR, 0.61), and male sex (RR, 0.31) were less likely to achieve CR. Advanced stage disease (hazard ratio [HR], 1.71 in stage III/IV), poor CCRT response (HR, 2.82 in PR, 4.47 in SD, 4.77 in PD compared to CR), and poor performance status (HR, 1.38 in ECOG 2–4) were found to increase mortality. @*Conclusions@#Advanced stage disease, poor performance status, male sex, and circumferential involvement were independent predictive factors for a poor response to CCRT. Advanced stage, poor performance status, and poor CCRT response were independent factors for decreased survival.

ABSTRACT

BACKGROUND/AIMS: School nurses’ knowledge of inflammatory bowel disease (IBD) has not been evaluated. We aimed to investigate school nurses’ knowledge of IBD and determine whether education could improve this knowledge. METHODS: School nurses were invited to complete self-reported questionnaires on IBD. Then, IBD specialists from tertiary referral hospitals provided a 60-minute lecture with educational brochures on two occasions, with a 3-month interval. Within 6 months after the educational interventions, school nurses were asked to complete the same IBD questionnaire via e-mail. RESULTS: Among 101 school nurses who were invited to participate, 54 nurses (53.5%) who completed two consecutive questionnaires were included in this study (median age, 45 years; range, 25 to 59 years; 100% female); 11.1% and 7.4% of the study participants had no knowledge regarding ulcerative colitis and Crohn’s disease, respectively. They had heard of IBD most frequently from doctors (33.3%), followed by internet sources (25.9%). After 6 months, the number of nurses who could explain IBD to students with over 30% confidence increased from 24 (44.5%) to 42 (77.8%) (p < 0.001). Most nurses (81.5%) reported that the educational intervention was helpful for managing students with abdominal pain or diarrhea. The number of students who received IBD-related welfare services from the Daegu Metropolitan Office of Education doubled when compared with the corresponding number during the prior educational year. CONCLUSIONS: There is room for improvement in school nurses’ knowledge of IBD. A systematic educational program on IBD should be implemented for these nurses.

ABSTRACT

BACKGROUND/AIMS@#The Internet is the main resource for health-related information. The incidence of inflammatory bowel disease (IBD) is rapidly increasing in Asian countries. However, the quality of websites for IBD available in this region has not been evaluated. We aimed to evaluate the quality of the information on IBD obtained from Korean websites.@*METHODS@#Using the terms “Crohn’s disease” or “ulcerative colitis,” websites were selected from those obtained with the three most renowned search engines in Korea; 60 websites from the results of each engine were chosen. The websites were classified into institutional, commercial, charitable, supportive, or alternative medicine types according to the characteristics of each site. The websites were evaluated regarding content quality using the validated DISCERN instrument and the Journal of the American Medical Association benchmarks.@*RESULTS@#The median score of all the websites according to the DISCERN instrument was 32 (interquartile range, 25 to 47) out of 80, indicating an insufficient overall quality of information. The alternative medicine sites scored the lowest, whereas the institutional sites scored the highest (p < 0.05). The quality of information was significantly different among the search engines (p = 0.028). The rank of appearance in the Google search result did not correlate with the quality level of the information.@*CONCLUSIONS@#The quality of information on the Internet regarding IBD varied according to the website type and search engine. Accreditation and quality assurance systems should be implemented for websites to ensure that the public and patients obtain accurate information on IBD.

ABSTRACT

BACKGROUND/AIMS: This study aimed to elucidate the prevalence of hepatitis B virus (HBV) serologic markers in Korean patients newly diagnosed with, but not yet treated for inflammatory bowel disease (IBD). METHODS: We prospectively enrolled 210 patients newly diagnosed with IBD (109 with ulcerative colitis and 101 with Crohn's disease). Hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (anti-HBs), and hepatitis B core antibody (anti-HBc) levels were measured and compared with those of 1,100 sex- and age-matched controls. RESULTS: The prevalence of chronic HBV infection (positive HBsAg, positive anti-HBc, and negative anti-HBs results) and past infection (negative HBsAg, positive anti-HBc, and positive or negative anti-HBs results) were not significantly different between the patients and controls (chronic HBV infection: IBD, 3.8% vs. control, 4.9%, P=0.596; past infection: IBD, 26.2% vs. control, 28.8%, P=0.625). The patients with IBD aged < 20 years were at a higher susceptibility risk (nonimmune) for HBV infection than the controls (IBD, 41.5% vs. control, 22.4%; P=0.018). In the multivariate analysis, an age of < 20 years (P=0.024) and symptom duration of ≥12 months before diagnosis (P=0.027) were identified as independent risk factors for nonimmunity against HBV infection. CONCLUSIONS: The patients newly diagnosed with IBD were susceptible to HBV infection. The frequency of nonimmunity was high, especially in the patients aged < 20 years and those with a longer duration of symptoms before diagnosis. Therefore, it is necessary to screen for HBV serologic markers and generate a detailed vaccination plan for patients newly diagnosed with IBD.

ABSTRACT

Bochdalek hernia (BH) is defined as herniated abdominal contents appearing throughout the posterolateral segment of the diaphragm. It is usually observed during the prenatal or newborn period. Here, we report a case of an adult patient with herniated omentum and colon due to BH that was discovered during a colonoscopy. A 41-year-old woman was referred to our hospital with severe left chest and abdominal pain that began during a colonoscopy. Her chest radiography showed colonic shadow filling in the lower half of the left thoracic cavity. A computed tomography scan revealed an approximately 6-cm-sized left posterolateral diaphragmatic defect and a herniated omentum in the colon. The patient underwent thoracoscopic surgery, during which, the diaphragmatic defect was closed and herniated omentum was repaired. The patient was discharged without further complications. To the best of our knowledge, this case is the first report of BH in an adult found during a routine colonoscopy screening.

ABSTRACT

This study compared the efficacy of DA-9601 (Dong-A ST Co., Seoul, Korea) and its new formulation, DA-5204 (Dong-A ST Co.), for treating erosive gastritis. This phase III, randomized, multicenter, double-blind, non-inferiority trial randomly assigned 434 patients with endoscopically proven gastric mucosal erosions into two groups: DA-9601 3 times daily or DA-5,204 twice daily for 2 weeks. The final analysis included 421 patients (DA-5204, 209; DA-9601, 212). The primary endpoint (rate of effective gastric erosion healing) and secondary endpoints (cure rate of endoscopic erosion and gastrointestinal [GI] symptom relief) were assessed using endoscopy after the treatment. Drug-related adverse events (AEs), including GI symptoms, were also compared. At week 2, gastric healing rates with DA-5204 and DA-9601 were 42.1% (88/209) and 42.5% (90/212), respectively. The difference between the groups was −0.4% (95% confidence interval, −9.8% to 9.1%), which was above the non-inferiority margin of −14%. The cure rate of gastric erosion in both groups was 37.3%. The improvement rates of GI symptoms with DA-5204 and DA-9601 were 40.4% and 40.8%, respectively. There were no statistically significant differences between the two groups in both secondary endpoints. AEs were reported in 18 (8.4%) patients in the DA-5204 group and 19 (8.8%) in the DA-9601 group. Rates of AE were not different between the two groups. No serious AE or adverse drug reaction (ADR) occurred. These results demonstrate the non-inferiority of DA-5204 compared to DA-9601. DA-5204 is as effective as DA-9601 in the treatment of erosive gastritis. Registered randomized clinical trial at ClinicalTrials.gov (NCT02282670)

ABSTRACT

BACKGROUND/AIMS: We aim to evaluate the efficacy and safety of combination therapy in erosive reflux disease (ERD) patients by comparing endoscopic healing rates according to the Los Angeles classification for esomeprazole alone, and esomeprazole plus mosapride. METHODS: A total of 116 ERD patients were randomized to receive esomeprazole 40 mg once daily plus mosapride 5 mg 3 times daily (E+M group), or esomeprazole plus placebo (E only group) for 8 weeks. Patients recorded gastroesophageal reflux disease (GERD) symptom questionnaire at weeks 4 and 8. The primary endpoint was the endoscopic healing rate of ERD after 8 weeks of treatment. RESULTS: Endoscopic healing rates according to the Los Angeles classification was 32 (66.7%) in the E+M group and 26 (60.5%) in the E only group, but there was no statistically significant difference between the groups. Only at 4 weeks, the total GERD symptom score changes relative to the baseline significantly improved in the E+M group than that of the E only group (−13.4 ± 14.7 vs −8.0 ± 12.3, P = 0.041), and upper abdominal pain and belching score changes showed significantly improved in the E+M group than that of the E only group (P = 0.018 and P = 0.013, respectively). CONCLUSIONS: The combination of a proton pump inhibitor with mosapride shows a tendency for upper abdominal pain, belching, and total GERD symptoms scores to improve more rapidly. This suggests that combination therapy with esomeprazole and mosapride will be useful for rapid improvement of specific GERD symptoms, such as upper abdominal pain and belching in ERD patients.

ABSTRACT

BACKGROUND/AIMS: The efficacy of bispectral index (BIS) monitoring during colonoscopic sedation is debated. We aimed to determine whether BIS monitoring was useful for propofol dose titration, and to evaluate differences in sedative administration between expert and inexperienced medical personnel during colonoscopy procedures that required moderate sedation. METHODS: Between February 2012 and August 2013, 280 consecutive patients scheduled to undergo a screening colonoscopy participated in this study and were randomly allocated to the expert or inexperienced endoscopist group. Each group was further divided into either a BIS or a modified Observer's Assessment of Alertness/Sedation Scale (MOAA/S) subgroup. Trained nurses administered combined propofol sedation and monitored sedation using either the BIS or MOAA/S scale. RESULTS: The mean BIS value throughout the procedure was 74.3 +/- 6.7 for all 141 patients in the BIS group. The mean total propofol dose administered in the BIS group was higher than that in the MOAA/S group, independently of the endoscopists' experience level (36.9 +/- 29.6 and 11.3 +/- 20.7, respectively; p < 0.001). The total dose of propofol administered was not significantly different between the inexperienced endoscopist group and the expert endoscopist group, both with and without the use of BIS (p = 0.430 and p = 0.640, respectively). CONCLUSIONS: Compared with monitoring using the MOAA/S score alone, BIS monitoring was not effective for titrating the dose of propofol during colonoscopy, irrespective of colonoscopist experience.

ABSTRACT

BACKGROUND/AIMS: Argon plasma coagulation (APC) has some merits in the treatment of gastric neoplasms including a shorter operative time and fewer complications compared with endoscopic mucosal resection or endoscopic submucosal dissection. However, there are few reports on the outcomes of gastric neoplasms treated using APC. The aim of this study was to evaluate APC in the treatment of early gastric neoplasms in terms of clinical efficacy, safety, and local recurrence. METHODS: We enrolled 28 patients who received APC therapy at the Kyungpook National University Hospital between May 2007 and April 2013. Clinical outcomes were analyzed. RESULTS: The median follow-up period was 24.8 months (range, 2 to 78). Among the 28 lesions treated using the APC procedure, tumor recurrence was encountered in seven lesions (25.0%). Recurrence was found in 50% (5/10) of single APC cases and 11% (2/18) of rescue APC cases. The mean time to recurrence was 16.1 months (range, 2 to 78). There were no serious APC-related complications such as perforation, bleeding, or infection. CONCLUSIONS: APC therapy can be a useful treatment with a favorable safety profile for patients with early gastric neoplasms. However, further studies are necessary to determine the long-term prognosis of patients undergoing this treatment.

ABSTRACT

BACKGROUND/AIMS: Therapies of functional dyspepsia (FD) are limited. DA-9701 is a novel prokinetic agent formulated with Pharbitis semen and Corydalis Tuber. We aimed to assess the efficacy of DA-9701 compared with itopride in FD patients. METHODS: Patients with FD randomly received either itopride 50 mg or DA-9701 30 mg t.i.d after a 2-week baseline period. After 4 weeks of treatment, 2 primary efficacy endpoints were analyzed: the change from baseline in composite score of the 8 dyspeptic symptoms and the overall treatment effect. Impact on patients' quality of life was assessed using the Nepean Dyspepsia Index (NDI) questionnaire. RESULTS: We randomly assigned 464 patients with 455 having outcome data. The difference of the composite score change of the 8 symptoms between the 2 groups was 0.62, indicating that DA-9701 was not inferior to itopride. The overall treatment effect response rate was not different between the groups. When responder was defined as > or = 5 of the 7 Likert scale, responder rates were 37% of DA-9701 and 36% of itopride group. Patients receiving DA-9701 experienced similar mean percentage of days with adequate relief during the 4-week treatment period compared with those receiving itopride (56.8% vs 59.1%). Both drugs increased the NDI score of 5 domains without any difference in change of the NDI score between the groups. The safety profile of both drugs was comparable. CONCLUSIONS: DA-9701 significantly improves symptoms in patients with FD. DA-9701 showed non-inferior efficacy to itopride with comparable safety.

ABSTRACT

Endoscopic submucosal dissection (ESD) is widely accepted as an alternative treatment to surgical resection for gastric neoplastic lesions. Among the complications of gastric ESD, perforation is usually manifested as a pneumoperitoneum. Here, we report a patient with a right-sided pneumothorax, pneumoperitoneum, and pneumoretroperitoneum as complications of gastric ESD. The patient recovered without further complications using conservative treatment, including endoscopic clipping, nasogastric drainage, and insertion of a chest tube.

ABSTRACT

BACKGROUND/AIMS: The use of proton pump inhibitors or misoprostol is known to prevent the gastrointestinal complications of nonsteroidal anti-inflammatory drugs (NSAIDs). Rebamipide is known to increase the mucosal generation of prostaglandins and to eliminate free oxygen radicals, thus enhancing the protective function of the gastric mucosa. However, it is unknown whether rebamipide plays a role in preventing NSAID-induced gastropathy. The aim of this study was to determine the effectiveness of rebamipide compared to misoprostol in preventing NSAID-induced gastrointestinal complications in patients requiring continuous NSAID treatment. METHODS: We studied 479 patients who required continuous NSAID treatment. The patients were randomly assigned to groups that received 100 mg of rebamipide three times per day or 200 microg of misoprostol three times per day for 12 weeks. The primary endpoint of the analysis was the occurrence rate of gastric ulcers, as determined by endoscopy after 12 weeks of therapy. RESULTS: Of the 479 patients in the study, 242 received rebamipide, and 237 received misoprostol. Ultimately, 44 patients (18.6%) withdrew from the misoprostol group and 25 patients (10.3%) withdrew from the rebamipide group. There was a significant difference in withdrawal rate between the two groups (p=0.0103). The per protocol analysis set was not valid because of the dropout rate of the misoprostol group; thus, the intention to treat (ITT) analysis set is the main set for the efficacy analysis in this study. After 12 weeks, the occurrence rate of gastric ulcers was similar in the rebamipide and misoprostol groups (20.3% vs 21.9%, p=0.6497) according to ITT analysis. In addition, the therapeutic failure rate was similar in the rebamipide and misoprostol groups (13.6% vs 13.1%, p=0.8580). The total severity score of the gastrointestinal symptoms was significantly lower in the rebamipide group than in the misoprostol group (p=0.0002). The amount of antacid used was significantly lower in the rebamipide group than in the misoprostol group (p=0.0258). CONCLUSIONS: Rebamipide can prevent gastric ulcers when used with NSAIDs and can decrease the gastrointestinal symptoms associated with NSAID administration. When the possibility of poor compliance and the potential adverse effects of misoprostol are considered, rebamipide appears to be a clinically effective and safe alternative.

ABSTRACT

BACKGROUND/AIMS: Bacillus Licheniformis, a probiotic used in the treatment of diarrhea, has been shown to suppress the growth of pathologic bacteria. This study was performed to assess the therapeutic efficacy and safety of Zhengchangsheng(R) (Bacillus Licheniformis) in comparison with another probiotic, Bioflor(R) (Saccharomyces Boulardii) for the treatment of diarrhea. METHODS: Patients with diarrhea (n=158) were randomized to receive Zhengchangsheng(R) or Bioflor(R) for 5 days. The existence or non-existence of formed feces, changes in daily stool frequency, improvement of subjective symptoms, and changes in the severity of diarrhea were compared. RESULTS: Of the 158 full analysis set (FAS) patient population, 151 patients comprised the per protocol (PP) analysis. The rates of recovered to formed feces in the Bacillus and Saccharomyces groups were 91.0% vs. 95.0% in the FAS (P=0.326) and 90.5% vs. 96.1% in the PP analysis (P=0.169), respectively. The mean duration of diarrhea changing to formed feces was 3.15+/-1.10 days in the Bacillus group and 3.22+/-1.01 in the Saccharomyces group (P=0.695, FAS). The frequency of defecation, subjective symptoms, and degree of severe diarrhea were improved in both groups, however, there were no statistically significant differences between the 2 groups. Analysis of the 95% confidence intervals for the differences in the rate of recovery to formed feces between the 2 groups met the criteria for non-inferiority of Bacillus compared to Saccharomyces. No significant adverse events were observed during the study period. CONCLUSIONS: Zhengchangsheng(R) is not inferior to Bioflor(R) in therapeutic efficacy and is a safe and useful therapeutic agent for the treatment of diarrhea.

ABSTRACT

BACKGROUND/AIMS: We evaluated changes in liver function parameters and risk factors for the deterioration of liver function 12 months after percutaneous radiofrequency ablation (RFA) therapy in patients with hepatocellular carcinoma (HCC). METHODS: The subjects in this retrospective study comprised 102 patients with HCC who had undergone RFA therapy and exhibited no recurrence of HCC 12 months thereafter. Serial changes in serum total bilirubin and albumin, prothrombin time, and Child-Pugh score were evaluated before RFA and 3, 6, 9, and 12 months thereafter. Deterioration of liver function was defined when the Child-Pugh score increased by at least 2 at 12 months after RFA therapy. We determined the factors related to aggravation of liver function after RFA therapy. RESULTS: Liver function had deteriorated 12 months after RFA in 29 patients (28.4%). Serum albumin levels decreased significantly from before (3.7+/-0.1 g/dL, mean+/-SD) to 12 months after RFA therapy (3.3+/-0.1 g/dL, P=0.002). The Child-Pugh score increased significantly during the same time period (from 6.1+/-0.2 to 7.2+/-0.3, P<0.001). Pre-RFA thrombocytopenia (< or =100,000/mm3) was revealed as a significant risk factor for the deterioration of liver function after RFA. However, no patients had episodes of bleeding as a complication of RFA. CONCLUSIONS: Among the liver-function parameters, serum albumin level was markedly decreased in HCC patients over the course of 24 months after RFA therapy. A pre-RFA thrombocytopenia represents a major risk factor for the deterioration of liver function.

ABSTRACT

BACKGROUND/AIMS: 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. METHODS: 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. RESULTS: 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). CONCLUSIONS: There was no meaningful difference among the gabexate, nafamostat and placebo group.

ABSTRACT

PURPOSE: Gastric mucosal neoplastic lesions should have characteristic endoscopic features for successful endoscopic submucosal dissection. MATERIALS AND METHODS: Out of the 1,010 endoscopic submucosal dissection, we enrolled 62 patients that had the procedure cancelled. Retrospectively, whether the reasons for cancelling the endoscopic submucosal dissection were consistent with the indications for an endoscopic submucosal dissection were assessed by analyzing the clinical outcomes of the patients that had the surgery. RESULTS: The cases were divided into two groups; the under-diagnosed group (30 cases; unable to perform an endoscopic submucosal dissection) and the over-diagnosed group (32 cases; unnecessary to perform an endoscopic submucosal dissection), according to the second endoscopic findings, compared with the index conventional white light image. There were six cases in the under-diagnosed group with advanced gastric cancer on the second conventional white light image endoscopy, 17 cases with submucosal invasion on endoscopic ultrasonography findings, 5 cases with a size greater than 3 cm and ulcer, 1 case with diffuse infiltrative endoscopic features, and 1 case with lymph node involvement on computed tomography. A total of 25 patients underwent a gastrectomy to remove a gastric adenocarcinoma. The overall accuracy of the decision to cancel the endoscopic submucosal dissection was 40% (10/25) in the subgroup that had the surgery. CONCLUSIONS: The accuracy of the decision to cancel the endoscopic submucosal dissection, after conventional white light image and endoscopic ultrasonography, was low in this study. Other diagnostic options are needed to arrive at an accurate decision on whether to perform a gastric endoscopic submucosal dissection.

ABSTRACT

Amyloidosis is characterized by a deposition of insoluble fibrils in various organs and tissues. Amyloid deposition, in the gastrointestinal track, provokes a dysfunction of the organ, due to an accumulation of fibrils, and causes a variety of clinical symptoms and endoscopic findings. Primary amyloidosis in the gastrointestinal tract is rarely reported in Korea. We experienced a case of recurrent intestinal bleeding, in a 59-year-old female patient with primary amyloidosis. A colonoscopy revealed the presence of multiple large circular ulcers. In the entire colon, diffuse nodular lesions with edema and bleeding were found. A colonoscopic biopsy established the diagnosis of amyloidosis, to the exclusion of other disease components. We concluded that the patient had localized amyloidosis. Though a definitive therapeutic strategy has not been established for localized gastrointestinal amyloidosis, the patient has been successfully treated with a high-dose of steroids and azathioprine.

ABSTRACT

Villous adenomas of the stomach are rare, although they more frequently occur in the colon and rectum. Clinical symptoms are similar to gastric polyps, but acute or chronic bleeding with anemia occurs frequently. The size of tumors varies between 4 and 6 cm, and the malignant potential is greater when the tumor is larger. Complete resection with surgery or endoscopic resection is the treatment of choice. Endoscopic findings revealed a dome-like or pedunculated appearance. Microscopically, the tumor was composed of long fronds and papillations covered by columnar epithelia with a reduced number of goblet cells. We report a case of polyps with chronic intermittent and acute bleeding for 6 months, which was alleviated by endoscopic mucosal resection and was confirmed as a villous adenoma.

ABSTRACT

BACKGROUND/AIMS: Recent studies suggest that the prevalence of gastroesophageal reflux disease (GERD) is increasing in Korea. However, studies on risk factors for GERD have yielded inconsistent results. The aims of this study were to compare clinical features between symptomatic syndromes without esophageal injury (=non-erosive disease [NED]) and syndromes with esophageal injury (=erosive disease [ED]), and to determine risk factors associated ED. METHODS: A total of 450 subjects who visited gastroenterology clinics of six training hospitals in Daegu from March 2008 to April 2010 were consecutively enrolled. The subjects were asked to complete a questionnaire which inquired about gastroesophageal reflux symptoms. The questionnaire also included questions about smoking, alcohol drinking, consumption of coffee, use of drugs, exercise, and other medical history. The subjects were subdivided into NED and ED groups. RESULTS: The proportion of subjects in each NED and ED group was 172 (38.2%) and 278 (61.8%). Male gender, smoking, alcohol drinking, consumption of coffee, large waist circumference, infrequent medication of antacids, aspirin and NSAIDs, infrequent and mild GERD symptoms were all significantly associated with ED on univariate analysis. Age, hiatal hernia, diabetes mellitus, body mass index, change in weight during 1 year, and number of typical GERD symptoms were not independent risk factors for ED. However, the association between ED and alcohol drinking, infrequent medication of antacids, mild typical GERD symptoms remained as strong risk factors after adjustments on multivariate logistic analysis. CONCLUSIONS: Independent risk factors associated with ED were alcohol drinking, infrequent medication of antacids and mild typical GERD symptoms.
