Objective To evaluate the difference of oral sodium phosphate (NaP) and polyethylene glycol-electrolyte lavage solution (PEG-ELS) in the aspects of cleansing efficacy, tolerance, and safety in clinical practice, so as to provide evidence for clinical practice. Methods A systematic review of all the relevant randomized controlled trials (RCTs) was performed according the handbook of the Cochrane Collaboration. RCTs were identified from The Cochrane Library(Issue1,2004) MEDLINE(1980-2004), EMBASE(1984-2004),and CBM(1978-2004).Handsearching was also performed .RCTs comparing the two methods were selected .Tow reviewers independently assessed the quality of included trials and extracted data independently .Results Eighteen trials involving 3668 patients were included .Sub-group analysis was performed. Nap tablet had higher rate of adequate cleansing quality (RR1.08,95%CI1.02 to 1.05,p=0.01).Two-day ,divided-dose oral Nap was superior in the rate of adequate cleansing quality (RR1.27,95%CI1.06 to 1.52,p=0.009). .The. rate of adequate cleansing quality in right colon of Nap was lower than PEG-ELS(RR0.79,95%CI 0.64 to 0.98,p=0.03).The rate of abdominal cramps (RR 0.84,95%CI 0.72 to 0.99),the rate of abdominal fullness (RR 0.48,95%CI 0.26 to 0.89),the rate of nausea (RR 0.65,95%CI 0.56 to 0.76)and the percentage of patients who didn’t finished their prescribed regimen (RR 0.23,95%CI0.14 to 0.36)in Nap group were lower (plt;0.05).Conclusions Compared with PEG-ELS,Nap is superior in cleansing efficacy , patients’ tolerance ,safety and economy . It is possible to promote the use of Nap in clinical practice in China .
Objective To systematically review the efficacy and safety of polyethylene glycol and sodium phosphate in bowel preparation of capsule endoscopy. Methods We searched CNKI, CBM, WanFang Data, PubMed, EMbase, and The Cochrane Library (Issue 6, 2016) up to June 2016, to collect randomized controlled trials (RCTs) about polyethylene glycol and sodium phosphate in bowel preparation of capsule endoscopy. Two reviewers independently screened literatures, extracted data and assessed the risk of bias of included studies, and then meta-analysis was performed by using RevMan 5.0 software. Results A total of six RCTs involving 531 patients were included. The results of meta-analysis showed that: compared with the sodium phosphate solution group, the polyethylene glycol solution group had poor intestinal cleansing effect (OR=0.43, 95%CI 0.21 to 0.88,P=0.02), higher incidence of adverse reaction (OR=3.20, 95%CI 1.13 to 9.06,P=0.03); but shorter gastric retention time (OR=–11.61, 95%CI –13.71 to –9.51,P<0.000 01) and residence time in the small intestine (OR=–4.17, 95%CI –7.74 to –0.60,P=0.02). Conclusion The efficacy of oral polyethylene glycol is poor in cleaning effect and adverse reaction than sodium phosphate solution, but better in the digestive tract residence time for capsule endoscopy. Due to the limited quality and quantity of included studies, the above conclusion is still needed to be proved by more high-quality studies.
