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.
In order to further develop water skills and apply the water assisted colonoscopy technique more flexibly, the investigators designed this study.
64 studies on the registry are indexed under Rectal Diseases; 14 are open to participants now.
This study's planned enrollment of 600 is above the median of 124 across 43 interventional studies indexed under Rectal Diseases.

Exclusion Criteria:
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.
Other: Air insufflation
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.
Other: Water injection
" 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.
Other: " Air assisted" water injection.
Air is inflated into the bowel to help searching the cavity while advancing the colonoscope until reaching the cecum.
Water was injected through the working channel instead of air to follow the intestinal cavity until reaching the caecum .
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.
