New study seeks to predict when keyhole surgery for blocked bowel fails
NCT ID NCT07350447
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This observational study will look at 170 adults who had emergency surgery for a small bowel blockage caused by scar tissue (adhesions). The goal is to find out what factors make it more likely that a surgeon will need to switch from a minimally invasive (laparoscopic) approach to a larger open incision (laparotomy). By identifying these predictors, doctors may be able to choose the best surgical approach from the start, potentially reducing complications and improving recovery.
