Descending perineum syndrome: a review of the presentation,diagnosis, and management

Introduction and hypothesis

Defecatory dysfunction is a relatively common and challenging problem among women and one that practicing pelvic reconstructive surgeons and gynecologists deal with frequently. A subset of defecatory dysfunction includes obstructed defecation, which can have multiple causes, one of which is descending perineum syndrome (DPS).

Methods

A literature search was performed to identify the pathophysiology, diagnosis, and management of DPS.

Results

Although DPS has been described in the literature for many decades, it is still uncommonly diagnosed and difficult to manage. A high index of suspicion combined with physical examination consistent with excess perineal descent, patient symptom assessment, and imaging in the form of defecography are required for the diagnosis to be accurately made. Primary management options of DPS include conservative measures consisting of bowel regimens and biofeedback. Although various surgical approaches have been described in limited case series, no compelling evidence can be demonstrated at this point to support surgical intervention.

Conclusions

Knowledge of DPS is essential for the practicing pelvic reconstructive surgeon to make a timely diagnosis, avoid harmful treatments, and initiate therapy early on.
