OBJECTIVE: To discuss the feasibility of water infusion colonoscopy and its difference with traditional air insufflation colonoscopy in application value.
METHODS: A prospective randomized controlled clinical study was designed to include 200 patients who underwent sedation-free diagnostic colonoscopy. Among them, 100 patients were treated with water infusion colonoscopy (observation group) and 100 patients were treated with air insufflation colonoscopy (control group). All operations were performed independently by the same experienced physician. The differences in colonoscopy related values, colon adenoma detection rate, and follow-up findings between the patients of two groups were compared.
RESULTS: There was no significant difference in the Boston bowel preparation scale (BBPS) score of the left hemicolon, transverse colon, right hemicolon, total BBPS scores, and bubble amount between the two groups (P>0.05). In the observation group, the scope-forward time, the time to reach the ileocecal junction, and the total operation time were significantly longer than that of the control group (P<0.01). The proportion of patients in whom the ileocecal junction was successfully reached was significantly higher in the observation group. The intraoperative abdominal pain visual analog scale (VAS) score, abdominal distension VAS score, the proportion of postural change, and the proportion of abdominal compression were all significantly lower in the observation group (P<0.05). There were no significant differences in the endoscope hardness adjustment rate, the scope withdrawal time, total detection rate of adenomas, and the size or location of colon adenomatous lesions between the two groups (P>0.05). Compared with control group, the incidence of abdominal pain and VAS scores were significantly lower in the observation group (P<0.05), and the willingness of patients to perform colonoscopy again was significantly higher (P<0.01).
CONCLUSION: Patients' tolerance and examination satisfaction are significantly better when using water infusion colonoscopy compared with traditional air insufflation colonoscopy, but the operation times are longer.
