Abstract
BACKGROUND AND AIMS Adequate bowel preparation is crucial for clear mucosal visualization during colonoscopy. We aimed to comprehensively compare oral sulfate solution (OSS) and 3-L split-dose polyethylene glycol (PEG) for bowel preparation before colonoscopy. METHODS This randomized, active-controlled, noninferiority study was performed in 10 medical centers. Eligible subjects were enrolled to receive OSS or 3-L PEG in a split-dose regimen. The quality of bowel preparation, adverse reactions, and acceptability were evaluated. The quality of bowel preparation was evaluated using the Boston Bowel Preparation Scale. Safety was evaluated by adverse reactions. The study population was divided into the full analysis set (FAS), the safety set, the modified FAS (mFAS), and the per-protocol set (PPS). RESULTS Three hundred forty-eight potentially eligible subjects were enrolled. Three hundred forty-four subjects were included in the FAS and safety set, 340 subjects were included in the mFAS, and 328 subjects were included in the PPS. Adequate bowel preparation of the OSS was not inferior to 3-L PEG in the mFAS (98.22% vs 97.66%) and the PPS (98.17% vs 98.78%). There was no significant difference in acceptability between the 2 groups (94.74% vs 94.80%, P = .9798). Overall adverse reactions were similar (50.88% vs 44.51%, P = .2370) between the 2 groups. CONCLUSIONS The split-dose OSS regimen was not inferior to the split-dose 3-L PEG regimen for the quality of bowel preparation in a Chinese adult population. The safety and acceptability of the 2 groups were similar. (Clinical trial registration number: NCT05465889.).

Observation of the application effect of low-volume polyethylene glycol electrolyte lavage solution (PEG-ELS) combined with ascorbic acid tablets in bowel preparation for colonoscopy in hospitalized patients. Front Oncol 2023; 13:1038461. [PMID: 37124529 PMCID: PMC10141285 DOI: 10.3389/fonc.2023.1038461] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Accepted: 03/21/2023] [Indexed: 05/02/2023] Open
Abstract
Background This study explored the effectiveness and safety of low-volume polyethylene glycol electrolyte lavage solution (PEG-ELS) combined with ascorbic acid tablets (PEG-ELS/Asc) in bowel preparation for a colonoscopy. Methods A total of 240 hospitalized patients who underwent a colonoscopy in Wenzhou People's Hospital, Wenzhou Third Clinical College of Wenzhou Medical University from July 2020 to June 2022 were randomly divided into two groups, with 120 patients each. All of the participants were given a low-residue or residue-free diet one day before the examination and fasted after dinner (completed before 18:00) the day before the examination. The 2-L PEG-ELS/Asc group took 2-L PEG-ELS plus 10 g ascorbic acid tablets once orally, while the 3-L PEG-ELS group took 3-L PEG orally on several occasions. The primary endpoint was the achievement of preparation adequacy and an overall colon cleansing score of ≥6, both assessed by blinded investigators using the Boston Bowel Preparation Scale (BBPS). The bowel cleansing effect, polyp detection rate, adverse reaction rate, oral drug tolerance rate, renal function, and electrolyte level changes were also compared between the two patient groups. Results There were no significant differences in the success rate of bowel preparation, the detection rate of polyps, or the adverse reaction rate between the two groups (P > 0.05). The tolerance rate of bowel preparation in the 2-L PEG-ELS/Asc group was significantly higher than that in the 3-L PEG-ELS group (93.3% vs. 80.23%) (P < 0.05). The levels of creatinine, serum potassium, serum sodium, and serum chlorine of the two groups before and after bowel preparation were within the normal range. In addition, the intestinal cleaning effect of the two preparation schemes for the hospitalized patients with diabetes and constipation is worse than that of those without these conditions (P < 0.05). Conclusion The effectiveness and safety of using 2-L PEG-ELS/Asc in bowel preparation for a colonoscopy in hospitalized patients were not inferior to using 3-L PEG-ELS. For patients with diabetes and constipation, the cleansing effect of the two bowel preparation options was not very satisfactory, and further clinical research is needed in this regard.

Abstract
BACKGROUND AND AIMS We evaluated the efficacy, safety and tolerability of novel oral sulphate tablets [OSTs] vs 2 L of polyethylene glycol and ascorbate [PEG/Asc] in patients with inflammatory bowel disease [IBD]. PATIENTS AND METHODS A total of 110 patients with clinically inactive IBD were enrolled in this single-blind multicentre non-inferiority study. Patients were randomly assigned to the OST or 2 L PEG/Asc group and we applied a split-dose regimen. The primary efficacy endpoint was bowel cleansing success rate defined as Harefield Cleansing Scale Grade A or B. The secondary endpoints were perfect preparation rate, the presence of air bubbles, safety as assessed by laboratory abnormalities and self-reported adverse events, or IBD symptom flare-ups. Tolerability was assessed by a pre-procedural visual analog scale [VAS] interview. RESULTS Both groups showed high cleansing success rates [98.1%] and there was no significant difference in perfect preparation rate. The proportion of a bubble score 0 was significantly higher in the OST group [94.5% vs 50.0%, p < 0.001]. There was no significant intergroup difference in vomiting or bloating. Symptom flare-ups occurred in two OST group patients. No clinically significant blood test abnormalities were noted in either group. Ease of ingestion and taste scores were significantly higher in the OST group. More patients in the OST group [94.5%] wanted to take the same preparation agent for their next colonoscopy. CONCLUSIONS Both OST and 2 L PEG/Asc demonstrated high successful cleansing and safety in patients with inactive IBD. OST achieved higher satisfaction than 2 L PEG/Asc. Our results suggest that the OST split-dose regimen is effective and safe for patients with inactive IBD.

Comparison of 2 L Polyethylene Glycol Plus Ascorbic Acid and 4 L Polyethylene Glycol in Elderly Patients Aged 60-79: A Prospective Randomized Study. Dig Dis Sci 2022; 67:4841-4850. [PMID: 35048226 DOI: 10.1007/s10620-021-07354-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Accepted: 12/01/2021] [Indexed: 12/14/2022]
Abstract
BACKGROUND The bowel-cleansing efficacy and safety of 2 L polyethylene glycol (PEG) with ascorbic acid (2L PEG + Asc) has rarely been studied in the elderly population. In this randomized trial, we compared the bowel cleanliness, safety, and tolerability of 2L PEG + Asc with those of 4 L PEG in an elderly population aged 60-79. METHODS Study participants were randomized either to 2L PEG + Asc or 4L PEG. The primary endpoint was the success rate of bowel preparation, using the Boston Bowel Preparation Scale. Before colonoscopy, all participants were questioned about adverse events and tolerability regarding purgative ingestion. RESULTS A total of 347 individuals were enrolled (2L PEG + Asc, 174; 4L PEG, 173). Mean age in the 2L PEG + Asc and the 4L PEG was 69.3 ± 5.6 and 69.3 ± 5.0, respectively (P = 0.917). The rate for successful bowel cleansing was comparable between the 2L PEG + Asc (92%) and the 4L PEG (96%, P = 0.118). Total ingested liquid including purgative and water was lower in the 2L PEG + Asc group (2.9 L) than in the 4L PEG group (4.2 L, P < 0.001). The tolerability of purgative was superior in the 2L PEG + Asc (overall satisfaction, P < 0.001; willingness to reuse, P < 0.001). There were no serious adverse events during the trial. CONCLUSIONS The bowel-cleansing efficacy of 2L PEG + Asc was comparable to that of 4L PEG. Tolerability was superior in the 2L PEG + Asc group. For older people, 2L PEG + Asc is an efficacious and safe bowel cleanser. (Clinical trial registration number: KCT0004123).

Dig Endosc 2022; 34:1121-1133. [PMID: 35294782 PMCID: PMC9545996 DOI: 10.1111/den.14299] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2022] [Revised: 03/07/2022] [Accepted: 03/14/2022] [Indexed: 01/10/2023]
Abstract
OBJECTIVES Although oral sulfate solution (OSS) has been revealed to be not only safe and efficacious but also noninferior to polyethylene glycol with ascorbic acid (PEG + ASC), it is unclear whether OSS can ultimately increase the polyp detection rate (PDR) and adenoma detection rate (ADR). We performed this meta-analysis to estimate the effect of OSS on PDR and ADR during colonoscopy. METHODS We searched PubMed, EMBASE, and the Cochrane Library to identify relevant randomized controlled trials (RCTs) investigating the comparative effect of OSS versus PEG + ASC on the PDR and ADR during colonoscopy. Cecal intubation time (CIT), cecal intubation rate (CIR), and bowel preparation score were also evaluated. Review Manager (RevMan) version 5.3.0 was used to perform statistical analysis. RESULTS Eight RCTs involving 2059 patients fulfilled the selection criteria. Meta-analysis suggested that OSS significantly increased the PDR (47.34% vs. 40.14%, risk ratio [RR] 1.13, 95% confidence interval [CI] 1.03-1.24, P = 0.01) and ADR (44.60% vs. 38.14%, RR 1.17, 95% CI 1.03-1.33, P = 0.01) during colonoscopy. Subgroup analysis showed that the beneficial effects of OSS on PDR and ADR were consistent among patients with mean age >55 years and with body mass index <25 kg/m2 receiving outpatient colonoscopy, morning colonoscopy, and the 2-L bowel preparation protocol. Meanwhile, patients receiving OSS had a beneficial bowel preparation score. CONCLUSION Compared with polyethylene glycol-based regimens, the OSS bowel preparation regimen significantly increased the PDR and ADR in patients undergoing colonoscopy.

Abstract
BACKGROUND AND AIM The efficacy and safety of the recently introduced low-volume purgatives in elderly people are not well known. Therefore, in this trial, we aimed to evaluate and compare the efficacy of two low-volume agents, oral sulfate solution (OSS) and 2-L polyethylene glycol with ascorbic acid (PEG-Asc), in elderly people. METHODS A prospective, randomized, single-blinded, multicenter, non-inferiority trial was performed at three university-affiliated hospitals in South Korea. Outpatients aged 65-80 years, who underwent elective colonoscopy, were enrolled. The primary outcome was the rate of adequate bowel preparation assessed using the Boston Bowel Preparation Scale. RESULTS A total of 199 subjects were randomized into the OSS (n = 99) or the 2-L PEG-Asc (n = 100) group. Of them, 189 subjects were included in the analysis of the primary outcome (OSS group 95 vs PEG-Asc group 94). The proportion of adequate bowel preparation was 89.5% (85/95) in the OSS group and 93.6% (88/94) in the 2-L PEG-Asc group. OSS was not inferior to 2-L PEG-Asc according to the prespecified non-inferiority margin of -15% (95% confidence interval for the difference, -12.1 to 3.8). Vomiting (11.6% vs 2.1%) and thirst (24.2% vs 11.7%) were more common in the OSS group than in the 2-L PEG-Asc group. CONCLUSIONS OSS is an effective low-volume purgative that is non-inferior to 2-L PEG-Asc in elderly people. Both the low-volume agents were identified to be well tolerated and safe in the healthy elderly population.
