Instant Messaging Program (Wechat) Improve the Quality of Bowel Preparation

Colonoscopy is the gold standard in the diagnosis of colorectal disease. The success of colonoscopy depends on high-quality bowel preparation by patients. Inadequate bowel cleansing reduces the cecal intubation rate, and the polyp detection rate (PDR). It also increases costs, mostly due to repeated procedures. The quality of bowel cleansing has remained suboptimal even though numerous different products and regimens have been tested and compared in no fewer than six meta-analyses. Therefore, a completely different approach to improve bowel cleansing is welcome.

Here the investigators assume that instant messaging program (Wechat) delivery the detail and FAQ (Frequently Asked Questions) of bowel preparation instructions would improve the quality of the bowel preparation. The Wechat program has some advantages, 1. Wechat supports over 400 million users, nearly half of the mobile subscribers population in China; 2. Wechat provided a real time communications including voice messages, pictures and text exchange timely; 3.Compare with telephone, Wechat is economical of both time and money; 4. Compare with bowel preparation instructional software and litera or cartoon educational booklet, Wechat is more interactive and responsive.

Primary outcomes

  1. Adequate bowel preparation quality at the time of colonoscopy defined by Ottawa score<6

    Time frame: up to 5 months

    Ottawa score：A)cleanliness of each part of the colon: 0=excellent 1=good 2=fair 3=poor 4=inadequate B)fluid in whole colon: small=0 moderate=1 large=2

    The bowel preparation was considered inadequate if (1) inadequate visualization on colonoscopy defined by Ottawa score≥6; (2) the colonoscopy was cancelled because of poor bowel preparation; (3) incompleted colonoscopy because of inadequate bowel preparation (the Ottawa score was rated as 14 when patients with failed colonoscopy because of inadequate bowel preparation).

Secondary outcomes

  1. Polyp detection rate

    Time frame: up to 5 months

    The proportion of participants with at least one polyp in each group

  2. Compliance rate to instruction

    Time frame: up to 5 months

    The proportion of participants compliance to the instructions of diet and bowel preparation in each group

  3. Willingness undergo a repeated bowel preparation

    Time frame: up to 5 months

    The number of participants have a willingness to undergo a repeated bowel preparation if needed
