基于结肠镜与CT结肠成像一体化检查的肠道 准备改良方法研究.

Objective To explore an integrated new method in intestinal preparation of colonoscopy and computed tomographic colonography (CTC). Methods The date of 39 patients who underwent colonoscopy and CTC in this hospital from July 2020 to March 2022 were selected for the study. The patients were randomly divided into the traditional method group and the improved method group. The traditional method group received 2.5 liters of compound polyethylene glycol (PEG） electrolyte powder for intestinal preparation, and the improved method group received two liters of compound PEG electrolyte powder combined with mosapride citrate. The drug tolerance, scores of Boston intestinal scoring system of colonoscopy, colon inflatation, cleanliness and imaging quality of CTC for between two groups were evaluated. Results The proportion of improved method group was significantly higher than traditional method group in the first-grade tolerance which was easily accepted by patients, the difference was statistically significant (P<0.05）.For the Boston intestinal scoring system of colonoscopy, the scores of each section were similar in using the two methods, but the total score of the improved method group was significantly higher than that of the traditional method group, the difference was statistically significant (P<0.05）.The inflatation and cleanliness scores of each segment of the intestine in the two groups were between two to three points, and there was no significant difference (P>0.05）.（4） In addition to the colonic wall display clarity, other CTC image quality indexes of the improved method group were better than those of the traditional method group, but there was no significant difference between the two methods (P>0.05）.Conclusion The combination of PEG and mosapride is suitable for colonoscopy and CTC, which can be used as an integrated method in intestinal preparation before colonoscopy and CTC.
