Puborectalis Syndrome as a Phenotype of Dyssynergic Defecation in Chronic Constipation: a Comparative Study of Defecography,High-resolution Anorectal Manometry, and Pelvic Floor Ultrasound
2026年6月28日 更新者:Weidong Tong、Third Military Medical University
Patients with suspected DD who met the Rome IV criteria were divided into the DD group and other types of constipation groups.
The differences between the two groups were analyzed to explore the precise diagnostic scheme for DD.

詳細な説明
This study was conducted solely at the Army Specialized Medical Center and was a single-center, bidirectional cohort study.
Patients with suspected dyssynergic defecation who visited the constipation specialty clinic of Daping Hospital were collected.
After the patients signed the informed consent form, they were asked to fill out the questionnaire (general clinical data questionnaire, Wexner constipation rating scale, ODS rating scale, and constipation patient quality of life scale (PAC-QOL)).
The baseline data of the patients (such as age, gender, symptoms, constipation scale scores, intestinal satisfaction scores, etc.) and the results of anorectal manometry, defecography, and perineal ultrasound were statistically analyzed.
Patients meeting the Rome IV criteria were grouped through DFG, ARM, and pelvic floor ultrasound examination.
The differences in clinical main symptoms, constipation scores, defecography, perineal ultrasound, etc. between the two groups were observed, and the roles and correlations of each parameter in diagnosis were analyzed.
