Abstract:
Objective:To evaluate the efficacy and safety of linaclotide with polyethylene glycol in bowel preparation.Methods:From September 2021 to February 2022, 240 patients who visited the Department of Gastroenterology, Third People′s Hospital of Hubei Province, Jianghan University and underwent colonoscopy were selected. According to the random number table, in the ratio of 1 to 1, the patients were divided into the linaclotide with polyethylene glycol group and the simple polyethylene glycol group, with 120 cases in each group. The patients in the linaclotide with polyethylene glycol group took 580 μg linaclotide and 2 L polyethylene glycol electrolyte powder solution, and the patients in the simple polyethylene glycol group took 3 L polyethylene glycol electrolyte powder solution. The Boston bowel preparation scale(BBPS) score, the detection rate of polyps or adenomas, the insertion time of colonoscopy, the withdrawal time of colonoscopy, the time of the first defecation, the frequency of defecations, the success rate of cecal intubation, the occurrence of adverse effects and the satisfaction rate of patients were compared between the 2 groups. Independent sample t test and chi-square test were used for statistical analysis. Results:A total of 235 patients completed bowel preparation and accepted colonoscopy. There were no statistically significant differences in the BBPS score, the detection rate of polyps or adenomas, the insertion time of colonoscopy, the withdrawal time of colonoscopy, the success rate of cecal intubation and the frequency of defecations between the linaclotide with polyethylene glycol group and simple polyethylene glycol group(7.3±1.1 vs. 7.0±1.2; 58.1%, 68/117 vs. 60.2%, 71/118; 38.5%, 45/117 vs. 39.8%, 47/118; (4.2±1.9) min vs.(4.3±1.6) min; (5.9±2.7) min vs.(6.2±2.4) min; 100.0%, 117/117 vs. 100.0%, 118/118; 5.3±2.3 vs. 5.1±2.7; all P>0.05). The rate of adverse effects of the linaclotide with polyethylene glycol group was lower than that of simple polyethylene glycol group(25.6%, 30/117 vs. 39.8%, 47/118), the satisfaction rate of patients was higher than that of the simple polyethylene glycol group (93.2%, 109/117 vs. 76.3%, 90/118), and the differences were statistically significant( χ2=0.24 and 0.64, P=0.018 and 0.031). Conclusion:Compared with the 3 L polyethylene glycol regimen, 580 g linaclotide with 2 L polyethylene glycol regimen can achieve the same bowel preparation effect with higher safety and patient satisfaction, which is worthy of clinical application.
