Study Objective:
To analyze whether a history of uterine surgery correlates with disease severity in patients with bladder deep infiltrating endometriosis (DIE).
Design:
This was an observational, cross-sectional study using data collected prospectively (Canadian Task Force classification II-2).
Setting:
A single university tertiary referral center.
Patients:
We included all nonpregnant women younger than age 42 years who had undergone complete surgical exeresis of endometriotic lesions. For each patient, a standardized questionnaire was completed during a face-to-face interview that was conducted by the surgeon in the month preceding the surgery.
Interventions:
One hundred seven women with histologically proven bladder DIE were enrolled in this study. For the purpose of the study, the women were assigned to 2 groups before surgery: a study group that included women with a history of a scarred uterus (SU) (SU+, n = 16) and a control group that included women without SU (SU-, n = 99). Both groups were compared in terms of their general characteristics, medical histories, surgical findings, and the severity of the disease.
Measurements And Main Results:
Patient age and body mass index were higher for the SU+ group as compared to the SU- group (37.9 ± 5.6 vs 32.2 ± 4.7, p < .01, and 24.7 ± 4.9 vs 21.9 ± 2.9, p = .03, respectively). Preoperative painful symptom scores did not differ between the 2 groups. No significant difference was observed in the rates of history for surgery for endometriosis (n = 11 [68.7%] vs n = 49 [53.8], p = .27). Comparison of the anatomic distribution of the lesions did not reveal a significant difference. The total American Society for Reproductive Medicine score did not differ between the groups (32.0 ± 34.4 vs 35.5 ± 34.5, p = .71). The incidence rate of isolated bladder DIE did not differ between the 2 study groups (n = 6 [37.5%] vs n = 40 [43.9%], p = .79).
Conclusion:
SU before surgery for endometriosis was observed in 14.9% of cases of bladder DIE; however, this was not related to an increased severity of the disease. This observational study hence does not appear to support the pathophysiologic hypothesis of a transmyometrial source for bladder DIE.
