NCT ID NCT07589465
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether giving lactulose, a mild laxative, after complex appendix surgery helps the bowels start working again sooner. 150 adults will receive either lactulose or a placebo for a few days after their operation. The main goal is to see how quickly they can pass stool and eat solid food without problems.
