Study Summary

The purpose of this study is to understand how a drug called Linaclotide improves bowel function and abdominal pain in patients with Irritable Bowel Syndrome with Constipation (IBS-C) as well as to examine whether Linaclotide alters communication between the brain and pelvic-floor region. Linaclotide has been shown to improve abdominal pain and bowel symptoms in IBS-C, and is approved by the FDA for the treatment of this condition. However, how exactly this drug works to relieve abdominal pain and discomfort in humans is not clearly known. Studies in animal models suggest that patients with IBS-C have hypersensitivity in the gut. Consequently, in IBS-C patients, there is rapid and excessive conduction of signals both from the brain and central nervous system region towards the pelvic-floor (anorectal axis) and the reverse direction. The investigators hypothesize that treatment with Linaclotide may improve/normalize these signals and thereby improve bowel symptoms. Investigators will test this theory using a new, noninvasive (and established) method of studying this communication pathway between the brain and gut.

Primary Outcome

A rectal catheter will be inserted into the rectum, up to 10 cm from the anal verge. The threshold for first sensation and pain will be determined by increasing the electrical stimulation in steps of 1 mA. subsequent stimuli will be applied at an intensity of 75% of the difference between the first sensation and pain thresholds. The CEPs will be recorded in a quiet room in a semi-recumbent position. Four runs of 50 stimuli will be averaged for both the rectal and anal stimulation studies, with a
