Background/Aims: The adenomatous colorectal polyps are known to be the precursors lesions of colorectal cancer. The aim of our study was to determinate whether the use of water pump in colonoscopy significantly improve the prevalence of polyps and rate of adenoma detection and therefore could be recommended in every endoscopy unit for potentially more effective cancer prevention.
Methods: All endoscopy and pathology reports of adult patients underwent colonoscopy at Zhumc between June 2017 and June 2018 were studied retrospectively. The water pump introduced in 15th December 2017. Data were compared between two groups: pre and post installation of pump with six months margin.
Results: 1006 eligible patients (mean age 56, male to female ratio 1:1) of which 532 in the pre-pump group and 474 in the post-pump group with similar baseline characteristics were compared concerning prevalence of polyps and rate of adenoma detection. Prevalence of polyps was 36% in the pre-pump group versus 38% in the post-pump group with no statistical significant difference between the two groups: (P = 0.662). Rate of adenoma detection was 26.2% for the first group versus 27.1% for the second group with again no significant difference between the two groups: (P = 0.82). Mean number of polyps of less than 5 mm were also compared between the two groups with no significant difference. The chi square test was performed for comparison between results.
Conclusion: The use of water pump had no effect on the detection of adenomatous lesions. On the other hand, with the use of water pump the procedure is faster, easier and therefore more effective in means saving time and effort and achieving the same results.
