Study start date: February 1, 2013

Actual date on which the first participant was enrolled.

Up to now, many studies has showed that compared with air insufflation colonoscopy, water-related colonoscopy could shorten the cecal intubation time and relieve the pain of the patients,especially for training the beginners，the effect was notable, but the present researches on water assisted technique has still been confined to following aspects:1.Water infusing was based on air insufflation; predetermined amount of water was infused ,and water was infused while passing through certain segment of the bowel(such as the left half of colon) ; 2.When training the first-learners, certain dose of sedatives or analgesics was injected; 3.The patients recruited were less. Colonoscopies in this study would be performed by experienced endoscopists of air insufflation colonoscopy, water would be injected completely instead of air insufflation while advancing the colonoscope, the amount of the water infused would not be predetermined but vary from individuals, and all the patients would be examined without any sedatives or analgesics.

Treatment Groups
Study Objectives

2 intervention groups are designated in this study

This study does not include a placebo group 

Treatment Groups

Group I

Active Comparator
Air insufflation colonoscopy is the conventional colonoscopy,which is inflating air to help searching the bowel cavity while advancing the colonoscope until reaching the cecum.All the patients were examined without sedation during the whole procedure.

Group II

Experimental
Water injection colonoscopy : Cut off air inflating before examination. Water was injected through the working channel to follow the intestinal cavity until reaching the caecum .All the patients were examined without sedation during the whole procedure.
