RESUMO

Background/Aims@#The quality of bowel preparation is one of the quality indicators for colonoscopy. The aim of this study was to compare the efficacy of oral sulfate solution (OSS) and polyethylene glycol plus ascorbic acid (PEG-AA) for bowel preparation. @*Methods@#The study involved 167 patients who underwent diagnostic colonoscopies. Inadequate bowel preparation was defined as any score of ≤1 in each colon section based on the Boston Bowel Preparation Scale. Multivariate logistic regression was used to compare the efficacy of OSS and PEG-AA. Subgroup analyses were performed based on patient characteristics. @*Results@#Overall, 106 (63.5%) patients received OSS, and 61 (36.5%) patients received PEG-AA. The rate of inadequate bowel preparation was 12.3% in patients receiving OSS and 32.8% in patients receiving PEG-AA (p=0.001). OSS (odds ratio [OR] = 0.26; p=0.003) and morning examination (OR=0.11; p=0.038) were significantly associated with efficient bowel preparation. The efficacy of OSS compared with PEG-AA was only significant in patients ≥50 years of age vs. <50 years of age (OR=0.13; p=0.001 vs. OR=0.96; p=0.959) and female vs. male patients (OR=0.06; p=0.002 vs. OR=0.58; p=0.339). @*Conclusions@#OSS was significantly more efficient for bowel preparation than PEG-AA, especially in patients ≥50 years of age and female patients. Morning examination led to a good quality of bowel preparation, irrespective of the preparation regimen.

RESUMO

BACKGROUND/AIMS: Recent Korean studies performed over the past few decades have shown diminishing efficacy and unacceptability of clarithromycin-based triple therapy as first-line eradication therapy for Helicobacter pylori infection, based on evidence of a declining eradication rate. Triple therapy continues to be used as first-line eradication therapy despite concerns regarding high clarithromycin resistance among Koreans. Patient compliance and acid suppression are important factors associated with the H. pylori eradication rate. We investigated whether regular administration of a proton pump inhibitor (PPI) 30 minutes before a meal can improve the eradication rate. MATERIALS AND METHODS: We retrospectively analyzed the data of 316 patients who were treated with first-line triple therapy (PPI, amoxicillin, and clarithromycin) for H. pylori infection between January 2012 and September 2017. Patients were divided into 2 groups based on the time of administration of the PPI (group A: before a meal, group B: after a meal). The urea breath test was performed 4~6 weeks after eradication of infection. RESULTS: Notably, 249 patients (78.8%, 249/316) showed successful eradication. The eradication rates in groups A and B were 87.5% (49/56 patients) and 76.9% (200/260 patients), respectively. We observed that regular administration of PPI before meals improved the eradication rate (P=0.079). CONCLUSIONS: We observed that although clarithromycin-based triple therapy was associated with an overall eradication rate <80%, regular PPI administration before meals improved the eradication rate. Regular PPI administration before meals and effective education to improve patient compliance could improve the eradication rate through maximal acid suppression.
