Elytrocele with and without a history of hysterectomy (303 defecography studies).

Objective: To search for clinical risk factors and symptoms of elytrocele in female patients without hysterectomy.

Patients And Methods: Of 1060 women who underwent defecography, radiographic evidence of elytrocele was observed in 303. History-taking was standardized, and included obstetric, surgical and medical history as well as clinical symptoms and their duration. Group A comprised 192 women with hysterectomy while group B included 111 women with no history of hysterectomy; these two groups were compared. Group B was also compared with patients who had neither elytrocele nor hysterectomy (group C; n=516).

Results: Women in group B (no hysterectomy) were younger than those in group A (with hysterectomy) (57.9 years versus 62.8 years; p<0.05). Patients in group B had fewer obstetric (87.4% versus 97.9%; p=0.01) and abdominal (64.9 versus 82.3%; p=0.01) surgical events than those in group A, but more urinary tract surgery (18.9% versus 10.9%) and higher infant birth weights than patients in control group C. Six women (2%) had no surgical or obstetric history: mean age 42.7 years (20.6-74 years). Group B used protection against urinary soiling less often (17.3% versus 29.07%; p=0.017), but had more fecal soiling (23.4% versus 13.6%; p=0.033). Defecography showed that women in group B had more external rectal prolapse (17.7% versus 4.9%; p=0.003) and cystocele (48.6% versus 34.9%; p=0.019) than those in group A.

Conclusions: This study was unable to identify risk factors of elytrocele in patients without hysterectomy except for a history of urinary tract surgery and higher infant birth weights. In some women, the elytrocele may be the result of significant rectal prolapse as part of a major pelvic floor disorder, predominantly in the posterior pelvis. Constitutional or congenital causes could also be involved as several young women free of any surgical or obstetric history nevertheless presented with an elytrocele.
