Summary

This study looks at people with chronic constipation to see if a specific muscle problem called puborectalis syndrome can be better identified using three different tests: defecography, high-resolution anorectal manometry, and pelvic floor ultrasound. Researchers will compare results between those with and without this condition to find the most accurate way to diagnose it. The goal is to improve diagnosis and treatment for people whose constipation is caused by this muscle issue.
