Feasibility and Reproducibility of Barostat Assessments of Colorectal Sensation During Colorectal Distention and Its Pharmacological Modulation Using Octreotide

A Multi-Center, Randomized, Double-Blind, Placebo-Controlled, Crossover Study in Women With Irritable Bowel Syndrome to Evaluate Feasibility and Reproducibility of Barostat Assessments of Colorectal Sensation During Colorectal Distention and Its Pharmacological Modulation Using Octreotide.

This study is designed to provide information on feasibility and reproducibility of barostat assessments of colorectal sensory functions and compliance and their pharmacological modulation
