ABSTRACT

Oral sulfate solution (OSS) is an emerging cleansing agent for bowel preparation. However, data comparing OSS to other conventional bowel preparations in Asian patients are limited. Therefore, the objective of this study was to compare the efficacy and tolerability of OSS to ascorbic acid plus polyethylene glycol (AA + PEG) in Asian patients. Methods: This was a prospective, randomized, parallel, investigator-blind study performed in two university hospitals in Korea. Bowel preparation efficacy was evaluated using both the Ottawa Bowel Preparation Scale (OBPS) and Boston Bowel Preparation Scale (BBPS). Results: Among 173 patients, 86 received OSS while 87 received AA + PEG for bowel preparation. Total OBPS score was 2.80 ± 2.48 in the OSS group and 4.49 ± 3.08 in the AA + PEG group, indicating significantly (p < 0.001) better efficacy with OSS. Total BBPS was higher in the OSS group (7.43 ± 1.49 vs. 6.51 ± 1.76, p < 0.001), indicating superior bowel preparation quality with OSS. Preparation-related adverse events were generally acceptable. Patients receiving OSS had more nausea (1.92 ± 0.94 vs. 1.54 ± 0.76, p = 0.004) and abdominal cramping (1.45 ± 0.78 vs. 1.17 ± 0.51, p = 0.006) than those receiving AA + PEG. However, overall satisfaction and taste were similar between the two groups. Conclusions: OSS had a non-inferior bowel cleansing efficacy than AA + PEG regardless of colon segment.

ABSTRACT

BACKGROUND/AIMS: Recent studies have suggested that the eradication of Helicobacter pylori (Hp) may lead to the regression of hyperplastic polyps (HPPs) in the stomach. We evaluated the sizes of HPPs after Hp eradication and we also compared the clinical parameters between the regression and non-regression groups. METHODS: We enrolled 187 patients who had HPPs in the stomach. The polyps were measured by using biopsy forceps, and the endoscopically observed changes of the polyps were assessed by two endoscopists. RESULTS: Total regression was observed in 68 patients of the eradicated group and in 6 patients in the non-eradicated group (42.5% vs. 22.2%, respectively, p<0.05). The non regression rate was significantly higher for the non-eradicated group than that for the eradicated group (33% vs. 10%, respectively, p<0.05). Comparing between the regression and non-regression groups, the incidence of polyps that were smaller than 10 mm in size and sessile was significantly higher in the regression group. Hp eradication was the only significant predictor of regression. CONCLUSIONS: Hp eradication could be a therapeutic option for Hp positive-hyperplastic gastric polyps, and especially for those that are less than 10 mm in size and sessile.
