Mid-term efficacy of surgical treatments for post-hysterectomy vaginal vault prolapse: a retrospective study.

Background: The surgical treatment of post-hysterectomy vaginal vault prolapse (PHVP) has been reported in several clinical studies, but mostly are short-term studies. This study aims to explore the mid-term efficacy of surgical treatments for PHVP. Methods: A total of 138 PHVP patients underwent surgery from January 2005 to January 2020 at the Fourth Medical Center of PLA General Hospital, Beijing. The clinical data of 119 patients who completed follow-up were retrospectively analyzed. Both groups of patients are diagnosed Pelvic Organ Prolapse Quantification system (POP-Q) III-IV stage of prolapse, with obvious prolapse-related symptoms and requiring surgical treatment. Among them, pelvic floor reconstruction surgery (RPS) was performed in patients who wanted to retain vaginal function and colpocleisis were used for frail patients who cannot tolerate RPS. We used the POP-Q scores for the objective efficacy evaluation, and use the Pelvic Floor Distress Inventory-Short Form 20 (PFDI-20) and Pelvic Floor Impact Questionnaire-7 (PFIQ-7) to evaluate the subjective symptom during follow up. Among them, 61 patients underwent pelvic floor RPS (Group R), and 58 received colpocleisis (Group C). Results: The surgeries in both groups were successfully completed, the median follow-up time after surgery was 4.3 years (0.25-13 years) and 5.3 years (0.33-15 years), respectively; the overall surgical success rate was 86.9% (53/61) and 100% (58/58), respectively; the subjective satisfaction rate was 90.2% (55/61) and 91.4% (53/58), respectively; and the PFDI-20 and PFIQ-7 scores in both groups were significantly improved compared with the preoperative levels (P<0.05). In Group R, 6 cases (9.8%, 6/61) were dissatisfied after surgery; in Group C, 5 cases (8.6%, 5/58) were dissatisfied after surgery. Conclusions: Reconstructive surgery and colpocleisis have a good mid-term effect on PHVP, with good outcome and few complications. The surgeon is expected to ascertain an appropriate surgical procedure based on the characteristics of the patient, the degree and the location of prolapse, in order to achieve the best surgical efficacy and minimize the damage.
