Brief Summary

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

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.

Air insufflation colonoscopy

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 Type ACTIVE_COMPARATOR

Air insufflation

Intervention Type OTHER

Air is inflated into the bowel to help searching the cavity while advancing the colonoscope until reaching the cecum.

Water injection colonoscopy

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 .The mucosa was observed by inflating the bowel with air while withdrawing the colonoscope.All the patients were examined without sedation during the whole procedure.

Group Type EXPERIMENTAL

Water injection

Intervention Type OTHER

Water was injected through the working channel instead of air to follow the intestinal cavity until reaching the caecum .

" Air assisted" water colonoscopy

" Air assisted" water injection colonoscopy: Cut off air inflating before examination. Water was injected through the working channel to follow the intestinal cavity until reaching the splenic flexure, small amount of air inflating could be given to help searching the cavity until reaching the cecum.All the patients were examined without sedation during the whole procedure.

Group Type EXPERIMENTAL

" Air assisted" water injection.

Intervention Type OTHER

Cut off air inflating before examination. Water was injected through the working channel to follow the intestinal cavity until reaching the splenic flexure, small amount of air inflating could be given to help searching the cavity until reaching the cecum.
