Primary purpose: DIAGNOSTIC

Brief summary: 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 investigators conduct this study to preform the "air assisted" water injection colonoscopy in experienced endoscopists.

Detailed description: In order to further develop water skills and apply the water assisted colonoscopy technique more flexibly, the investigators designed this study.

Eligibility criteria: Inclusion Criteria:

* Patients diagnostic colonoscopy;
* Subjets able to provide informed consent

Exclusion Criteria:

* Prior partial or complete colectomy;
* Patients who decline to participate;
* Patients with poor bowel preparation;
* Contraindications of the colonoscopy

Primary outcomes:
measure: The success rate of the cecal intubation
timeFrame: This will be calculated after the completion of the whole trial,which is about 2 months
Secondary outcomes:
measure: The cecal intubation time(min)
timeFrame: This will be collected at their procedure appointment which is expected to be 2 to 3 hours in length
measure: The time to reach the splenic flexure(min)
timeFrame: This will be collected at their procedure appointment which is expected to be 2 to 3 hours in length
measure: VAS abdominal pain score
timeFrame: Data collected usually within 10minutes post procedure
measure: The frequency of the colonoscope shortening maneuver while advancing the colonoscope
timeFrame: This will be collected at their procedure appointment which is expected to be 2 to 3 hours in length.
measure: Length of colonoscope at time of cecal intubation(cm)
timeFrame: This will be collected at their procedure appointment which is expected to be 2 to 3 hours in length.
measure: Volume of water used during water colonoscopy(ml)
timeFrame: This will be collected at their procedure appointment which is expected to be 2 to 3 hours in length.
