Summary
Brief summary (as posted)
It is estimated that about 20% of colonoscopies have inadequate preparation. (5) This is associated with lengthy procedures and less detection of adenomas, reduces the screening intervals, and increases the costs and risks of complications. Several strategies have been proposed to improve the quality of bowel preparation. Mobile healthcare Apps have been developed to increase adherence to bowel preparation agents, improving the quality of bowel preparation. However, adherence to mobile healthcare Apps is also a quality criterion and a pending problem to solve with this new technology. GastroBot is a new technology based on artificial intelligence that allows, through a software bot, to carry out a personalized follow-up of the patient's bowel cleansing, advising the patient to overcome contingencies that arise with the preparation, which in other circumstances could lead to the failure of it. The primary aim of this study is to determine the improvement in bowel preparation after GastroBot assistance compared with the traditional explanation. As a secondary aim, this study also pursues to determine adenoma and polyp detection rates (ADR and PDR, respectively), bowel preparation agents' tolerance, and GastroBot functionality.

- GastroBot-assisted bowel preparation group (GB-group)
- description
- Adult patients with no surgical high-risk comorbidities and colonoscopy indications for screening, surveillance, or diagnosis who are undergoing a colonoscopy. GastroBot assisted with the polyethylene glycol bowel preparation: patients will receive the instructions through the WhatsApp application, being guided by the software bot with multiple and personalized alternative instructions according to results.
