Clinical application of modified water infusion single colonoscopy / 中国内镜杂志

ABSTRACT

Objective To evaluate the clinical effect of modified water infusion single colonoscopy. Methods Seventy patients underwent single colonoscopy from June 2016 to June 2017 were selected and randomly divided (by means of random number table) into study group (n = 35) and control group (n = 35). The study group was given modified water infusion single colonoscopy, and the control group was given air insufflation single colonoscopy. The success rate of ileocecal inserted, times of cecal intubation and complications rates were recorded;Visual analogue scale (VAS) was used to assess the severity of abdominal pain and abdominal bloating. Results The success rate of ileocecal inserted and complications rates were not significantly different between the two groups (P > 0.05). Times of cecal intubation of study group (4.86 ± 1.66) min was significantly shorter than that of the control group (6.45 ± 2.34) min (P < 0.05). The mean abdominal pain score of study group was significantly lower than that of control group [(2.71 ± 1.05) vs (3.31 ± 1.13), P < 0.05]. The mean abdominal bloating score of study group was significantly lower than that of control group [(3.31 ± 1.05) vs (3.97 ± 1.10), P < 0.05]. Conclusion Modified water infusion colonoscopy is rapid and security, which can effectively improve the comfortableness of patients.
