Résumé
Despite the widely accepted association between excessive straining and perineal descent, the clinical significance of perineal descent in patients with obstructed defecation syndrome is still unclear. This study aimed to evaluate the prevalence of pathological perineal descent in patients with obstructed defecation syndrome and the impact of perineal descent on symptoms severity. This was a prospective multicenter uncontrolled study. The study involved 3 hospital pelvic-care centers and was conducted from January 2018 to January 2022. The study included 141 consecutive adult patients with an obstructed defecation syndrome score of 9 or more and no evidence of organic GI pathology. All the patients underwent dynamic pelvic MRI and, in case of suspected paradoxical puborectalis contraction, anal manometry. Main outcome measures were the prevalence of excessive perineal descent and the correlation between perineal descent and obstructed defecation syndrome score. One hundred twenty-eight patients (90.7%) completed magnetic resonance examination and were included in the analysis. Of these, 18 patients (14.1%) had a physiological perineal descent and 110 (85.9%) had an excessive perineal descent. Excessive perineal descent was found in 46.1% of patients (12/26) with MRI signs of paradoxical puborectalis contraction and in 96% of patients (98/102) with normal puborectalis relaxation. In this latter group of patients, a good correlation between obstructed defecation syndrome score and maximum perineal descent during straining was found (Spearman r test: 0.68; p < 0.0001). The study was limited by the small sample size and by the strong selection of the study population. Excessive perineal descent is a common finding in patients with obstructed defecation syndrome and high symptoms score, occurring almost consistently in patients without paradoxical puborectalis contraction. In these patients, the maximum perineal descent seems to be well correlated with symptoms severity. See Video Abstract at http://links.lww.com/DCR/C135 .

The study involved 3 hospital pelvic-care centers and was conducted from January 2018 to January 2022.
PATIENTS

Main outcome measures were the prevalence of excessive perineal descent and the correlation between perineal descent and obstructed defecation syndrome score.
RESULTS

One hundred twenty-eight patients (90.7%) completed magnetic resonance examination and were included in the analysis.
