PESTI Trial Summary

This trial is studying whether the drug pyridostigmine can help relieve symptoms of postoperative ileus, which is a condition that can occur after surgery in the large intestine. The trial will compare the effects of pyridostigmine to a placebo, and safety will be monitored throughout.

Who is the study for?
This trial is for adults who've had colorectal surgery and are now facing a condition called postoperative ileus, where the intestines don't move food properly causing bloating or nausea. Participants need to have normal organ function, not be pregnant or breastfeeding, and can't have other serious health issues like heart failure or bowel obstructions.Check my eligibility
What is being tested?
The study tests if Pyridostigmine Bromide can help with intestinal movement after surgery compared to a placebo. It's a double-blind trial, meaning neither patients nor doctors know who gets the real drug. Everyone continues standard care too.See study design
What are the potential side effects?
Participants will report side effects using a special scale. While not detailed here, Pyridostigmine may cause muscle cramps, diarrhea, increased saliva production, and could affect heart rate among other potential side effects.

What is the purpose of this research?

"The primary outcome of this pyridostigmine bromide clinical trial is the incidence of associated side effects, which will be measured over a 30-day period. Secondary outcomes include time to tolerance of solid food after postoperative ileus (defined as the amount of time from diagnosis until first tolerance of solid food), number of participants requiring re-operation (defined as the number who require a re-operation for any reason during the first 30 days following initial operation), and number of participants with complications (defined as those with any type of complication or adverse event occurring within the first 30 days following surgery)."
