Brief summary

Poor bowel preparation is common in inflammatory bowel disease (IBD) and non-IBD patients and can lead to incomplete colonoscopic assessments and missed pathology. As such the patients are required to undergo either a second colonoscopy or earlier surveillance colonoscopies. This creates cumulative risks of colonoscopies (double the anesthetic and procedural risks), increased burden to the health care system (extra resources and colonoscopy spots used that could be used by other patients) and the patient (more inconvenience of further bowel prep and missed work for the procedure) as well as financial costs both to the health care system as well as the patient in multiple ways. Other research has found patient reported bowel preparation quality (no bowel motion pictures) is often not accurate, Being able to assess the patient's bowel preparation before giving them anaesthetic and more importantly, being able to know their prep is poor and given them extra bowel prep and have their procedure delayed by a few hours (put at the end of the endoscopy list) would be of huge benefit for both the patient and the health care system. Our aim is to create a rapid ultrasound assessment (no radiation and no risks to the patient) that focuses on a few specific areas of the bowel to create a bowel prep scoring system which matches current validated colonoscopy bowel preparation scoring systems. Furthermore to show that by using the ultrasound scoring system that the detrimental effects of poor bowel preparation (discussed above) can be avoided and to create a cost-benefit analysis as well.

Interventions

Whether transadbominal ultrasound can accurately assess bowel preparation quality will be determined with observational comparisons with already scheduled colonoscopies and the Boston Bowel Prep Scale and patient reported bowel preparation quality. Both IBD patients and non IBD patients will be included in this study. The transabdominal ultrasound will be performed within 30minutes prior to the scheduled colonoscopy (after they have completed their bowel cleansing). The patients at this point ar

Whether transadbominal ultrasound can accurately assess bowel preparation quality will be determined with observational comparisons with already scheduled colonoscopies and the Boston Bowel Prep Scale and patient reported bowel preparation quality. Both IBD patients and non IBD patients will be included in this study. The transabdominal ultrasound will be performed within 30minutes prior to the scheduled colonoscopy (after they have completed their bowel cleansing). The patients at this point are already in a bed and in hospital gowns and being readied for their colonoscopy. With patient privacy in mind and their curtains closed, only their abdomen will be exposed and the rest covered with the bed sheets, towels and their gown as needed. Then ultrasound Jelly is applied to the abdomen and the ultrasound probes (curved and linear) will be used to obtain ultrasound images of the quality of the bowel prep. Then the jelly is simply wiped off and the patient is ready for their colonoscopy. From previous non-trial ultrasounds for other indications, de-identified images of possible degrees of faeces in the bowel can be used and a numerical scoring system developed (ie from collapsed bowel, to liquid, to semi-solid, to solid/dense material).
