Does Rectocele Repair Combined with Other Perineal Surgeries Affect Outcome Compared to Solo Rectocele Repair?

Objectives: Rectocele is common in female patients. To date, there is no literature comparing outcomes of rectocele repairs in combination with other perineal surgeries. We aim to analyze perioperative morbidity and mortality as well as long-term outcome of rectocele repair in combination with other perineal surgeries (RR combination) and compare this with solo rectocele repair (solo RR).

Design: The type of study was case-control. Data of patients who received solo rectocele repair or rectocele repair in combination with other perineal surgeries between January 2011 and December 2015 were identified and reviewed in a prospectively maintained and IRB-approved database. Ninety-eight patients were included, including 41 patients in the solo RR group and 57 patients in the RR combination group. The demographics, characteristics of patients, short-term complications, long-term complications, and morbidity of the 2 groups were observed.

Methods: The demographics, characteristics of patients, short-term complications, long-term complications, and morbidity of the 2 groups were compared, respectively. Covariate adjustment was analyzed by multivariate logistic and Cox regression analysis.

Results: Ninety-eight patients with a median age of 57 were included, involving 41 patients in the solo RR group and 57 patients in the RR combination group. Other than the operative approach (p < 0.01), demographics and preoperative characteristics of the 2 groups were comparable. All variables, including length of stay, estimated blood loss, self-limiting rectal bleeding, transfusion, urinary retention, rectal stricture, rectal and perineal infection, rectovaginal abscess, reoperation, effective resolution of obstructive defecation symptoms, residual symptoms rate, and recurrence rate, were comparable among the 2 groups except for operative time (p = 0.03).

Limitations: This study is a single-center study, which may cause bias. In addition, the sample size is limited. Staging of rectocele and routine imaging studies were not performed.

Conclusions: Rectocele repair in combination with other perineal surgeries is feasible, and outcomes are comparable with solo rectocele repair. Transanal versus transvaginal repairs appear to have no influence on outcomes.
