Abstract:
Objective:To explore the value of linaclotide combined with compound polyethylene glycol electrolytes powder (PEG) for bowel preparation for colonoscopy.Methods:A randomized and single blind prospective clinical study was conducted in patients who intended to receive colonoscopy at the Department of Gastroenterology in Shenzhen Hospital, Southern Medical University from June 2021 to August 2021. One hundred and fifty-two patients in the experimental group were treated with 580 μg linaclotide + 2 L PEG, and 152 patients in the control group were treated with 3 L PEG. The bowel preparation effects including Boston bowel preparation scale (BBPS) score, bubble score and lesion detection rate, and safety (adverse events) were compared between the two groups.Results:The total BBPS scores were 9 (8, 9) in the experimental group, and 9 (9, 9) in the control group with no significant difference ( Z=0.141, P=0.888). The bubble scores were 1 (1, 2) in the experimental group, and 1 (1, 1) in the control group with no significant difference ( Z=1.788, P=0.074). There was no significant difference in detection rate of lesions between the experimental group and the control group [37.50% (57/152) VS 33.55% (51/152), χ2=0.517, P=0.472]. There was no significant difference in safety including incidence of nausea [7.24% (11/152) VS 13.16% (20/152), χ2=2.910, P=0.088], vomiting [2.63% (4/152) VS 7.24% (11/152), χ2=3.436, P=0.064], abdominal distension [7.89% (12/152) VS 11.84% (18/152), χ2=1.331, P=0.249] and abdominal pain [2.63% (4/152) VS 4.61% (7/152), χ2=0.849, P=0.357] between the experimental group and the control group. Conclusion:Linaclotide combined with PEG for colonoscopic bowel preparation reduces drinking water volume. The cleaning effect and safety are comparable to using 3 L PEG. It can be recommended for bowel preparation for colonoscopy.
