Abstract
BACKGROUND/AIMS: Cul-de-sac hernias (enterocele and peritoneocele) are difficult to diagnose in patients presenting with primary evacuatory difficulty. Failure to recognize their presence in patients undergoing surgery may lead to poor functional outcome. Accurate diagnosis requires specialized investigation including dynamic evacuation proctography (DEP) or dynamic magnetic resonance (MR) imaging. Recently, dynamic transperineal ultrasonography (DTP-US) has been used for this purpose. This study compares DEP with DTP-US for the diagnosis of cul-de-sac hernias in those patients presenting with evacuatory dysfunction. MATERIALS AND METHODS: Sixty-two female patients with chronically obstructed defecation underwent blinded clinical, DEP, and DTP-US assessment to define the accuracy of diagnosis of cul-de-sac hernias. RESULTS: Both the DEP and the DTP-US techniques show concordance for the diagnosis of cul-de-sac hernias in an unselected patient cohort. Patients in both groups have the same duration of constipation with a greater likelihood of prior hysterectomy in those with cul-de-sac hernias. The diagnosis was established separately by DEP in 88% and in 82% of the cases by DTP-US. Transperineal sonography is discordant with DEP in 45% of cases once the diagnosis of cul-de-sac hernia is made, over the contents of the hernia and over the degree of transvaginal enterocele descent, where DTP-US tends to upgrade enterocele severity. Both techniques confirm the high incidence of concomitant pelvic floor compartment pathology. CONCLUSIONS: Both methods have accuracy for the diagnosis of cul-de-sac hernias in those patients presenting with evacuatory difficulty. Transperineal sonography tends to more readily diagnose peritoneocele and to upgrade enterocele extent. As an office procedure, it is a valuable adjunct to the clinical examination in the diagnosis of cul-de-sac hernia.
