ABSTRACT
Objective:To discuss the application of water-aided colonoscopy in the enteroscopy, and compare with traditional air insufflations colonoscopy so as to analyze the efficacy and safety of clinical enteroscopy.Methods: 248 patients accepted with non-anesthesia colonoscopy were enrolled in this study and they were divided into two groups (water-aided group,n=124, air insufflations group,n=124) as the random number table. All clinical data of two groups were collected, and the bowel preparation statuses of patients was evaluated when the colonoscopes were taken out. During detection, the success rate of intubation, the entrance time of colonoscope, the withdrawal time of colonoscope and the total time of examinations were recorded. After detection, the pains score of patients were recorded and evaluated, and a series of auxiliary operation in the process, such as the change of body position, abdominal compression and the adjustment for hardness were recorded. Results: The differences of bowel preparation status scores of left colon, transverse colon, right colon and the whole colon between two groups were not statistically significant(t=0.98,t=0.85,t=1.07,t=1.51;P>0.05). The difference of success rate of intubation between two groups was no significant(x2=0.73,P>0.05). The entrance time, the withdrawal time of colonoscope and the total time of intubation of water-aided group were significantly higher than these of air insufflations group, while the VAS of water-aided group was significantly lower than that of air insufflations group(t=5.78,t=3.85,t=5.64, t=10.25;P0.05).Conclusion: The water-aided colonoscopy can relieve pain of patients, and it doesn't affect the success rate of intubation for cecum.
