Description
Inclusion Criteria:
colonoscopists: All colonoscopists are selected from the colonoscopy learners in Endoscopy Center of Shanghai Renji Hospital. Only inexperienced colonoscopists (having performed less than 200 procedures) would be allowed to participate in the first part while both inexperienced colonoscopists and experienced colonoscopists (having performed less than 350 procedures) are allowed to participate in the second part.
patients: in the first part: Patients aged between 18 and 75 are recruited to receive unsedated colonoscopy examination with their permission. Written informed consent would be obtained.
in the second part:no patient would participate in this part
Exclusion Criteria: patients:consecutive patients,excluding inpatients,pregnant,who had a known or suspected colonic stricture or obstruction, who had previous history of abdominal surgery,who had severe comorbid cardiopulmonary,kidney,liver conditions,who had pacemakers or internal defibrillators,who were unable to give informed consent,who have active gastrointestinal bleeding are recruited

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: MEI colonoscopy Group
Patients would be randomly assigned to have colonoscopy examination performed by one inexperienced colonoscopist (having performed less than 200 procedures) with the assistance of magnetic scope navigation system
|
In the first part,patients would be randomly assigned to have colonoscopy examination performed by one inexperienced colonoscopist (having performed less than 200 procedures) with the assistance of magnetic scope navigation system In the second part colonoscopist would be randomized to perform conventional colonoscopy on a colon model with an MEI view while the force measurement device being used to collect data of colon force variation meanwhile.
No patients would be involved in this part.
All force variation data would be recorded by a image storage device.
Other Names:
|
No Intervention: Standard colonoscopy Group
Patients would be randomly assigned to have colonoscopy examination performed by one inexperienced colonoscopist (having performed less than 200 procedures) without the assistance of magnetic scope navigation system
|
|
Active Comparator: MEI colon model Group
Colonoscopist would be randomized to perform colonoscopy on a colon model with an MEI view while the force measurement device being used to collect data of colon force variation meanwhile. No patients would be involved in this part. All force variation data would be recorded by a image storage device. |

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
patients over pain experience
Time Frame: day of colonoscope performance
|
A pain score would be obtained from patients shortly after each examination.
The score would be obtained with the Help of a visual analogue scale ranging from 0(no pain)to10(the worst pain).
|
day of colonoscope performance
|
Maximum target colon loop force
Time Frame: day of colonoscope performance
|
In the second part,The maximum colon force exerted on a chosen target colon loop (we plan to choose one loop of sigmoid colon)would be recorded by the simple colon force measurement device.
|
day of colonoscope performance
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
number of attempts of abdominal hand pressure
Time Frame: day of colonoscope performance
|
day of colonoscope performance
|
|
number of patient reposition
Time Frame: day of colonoscope performance
|
day of colonoscope performance
|
|
endoscopist perception of ease of procedure
Time Frame: day of colonoscope performance
|
Endoscopist are asked to score the ease of each procedure after completion,using a ten-point scoring system(ease-of-procedure score)form 0(easiest)to 10(most difficult).
|
day of colonoscope performance
|
patient's intention to attend unsedated colonoscopy again
Time Frame: day of colonoscope performance
|
patients need to answer "yes"or"no"
|
day of colonoscope performance
|
caecal intubation rate
Time Frame: one year
|
Criteria for reaching the caecum are identification of the ileocaecal valve
|
one year
|
caecal intubation time
Time Frame: day of colonoscope performance
|
day of colonoscope performance
|
|
ime for the colonoscopist to advance to splenic flexure of colon
Time Frame: day of colonoscope performance
|
In the second part,time for the colonoscopist to advance to splenic flexure of colon would be recorded.
|
day of colonoscope performance
