Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Minimal water exchange colonoscopy is theoretically more convenient and faster than water exchange colonoscopy. But few studies compared the differences between the two methods. Therefore, we attempted to evaluate the effect of minimal water exchange colonoscopy prospectively.

Study Groups

minimal water exchange

We suctioned the lumen and infused water by constant pressure on the air-water valve button of the endoscope at the rectum to open the lumen.

Group Type EXPERIMENTAL

minimal water exchange

Intervention Type OTHER

Use a new technique, minimal water exchange colonoscopy, which adds the infusion of modest amounts of water by constant pressure on the air-water valve button of the endoscope to achieve intubation.

traditional water exchange colonoscopy

The water exchange colonoscopy reached the cecum through continuous infusion and suction of water in the whole colon via an additional flushing pump.

Group Type NO_INTERVENTION

No interventions assigned to this group

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Patients aged 18 to 75 years for unsedated colonoscopy for colorectal cancer screening, polyp surveillance, or polyp resection were enrolled.

Exclusion Criteria

* Patients who underwent sedation or analgesia before colonoscopy, and were reluctant to cooperate or provide informed consent. Those who were suffering from too serious diseases to tolerate the examination. The intestinal segment was incomplete or the colonoscopy did not reach the cecum.
