ClinConnect Summary

This clinical trial is studying how to predict when food or liquid stays in the stomach longer than it should before a sedated gastroscopy, which is a procedure where a doctor looks inside the upper digestive system using a small camera. When stomach contents don’t empty properly, it can make the procedure harder to perform and increase the risk of serious problems like reflux or choking while the patient is sedated. The goal of this study is to create an easy way for doctors to measure and understand how much stomach content remains and what factors, like age, health conditions, or medications, might affect this.

Adults aged 18 and older who are scheduled for an elective (planned) sedated gastroscopy or sedated combined gastro-colonoscopy may be eligible to join, as long as they don’t have active bleeding in their upper digestive tract, are not pregnant or breastfeeding, and meet other safety requirements. If you participate, you’ll have your medical history reviewed and undergo the planned procedure as usual, with extra attention to measuring stomach contents. This research will help doctors better prepare and manage patients undergoing these procedures to improve safety and outcomes.
