          Abstract

          Purpose

          To investigate the effect of total pelvic floor reconstruction with a six-arm mesh in the treatment of pelvic organ prolapse.

          Patients and Methods

          This is a retrospective observational cohort study. A total of 368 patients with pelvic organ prolapse underwent pelvic floor reconstruction surgery. Patients were categorized by the type of surgical mesh: 176 patients received a six-arm mesh and 192 patients received an anteroposterior approach mesh. The 1-year effect of the two groups was compared. The Pelvic Floor Distress Inventory Questionnaire (PFDI-20), Colorectal-Anal Distress Inventory (CRADI-8) and the Pelvic Organ Prolapse Quantitation (POP-Q) staging were used for evaluation. The incidence of complications was recorded. A cure standard was registered by a POP-Q score of grade I or below. A P value <0.05 indicates the difference is statistically significant.

          Results

          There was no recurrence documented in the patients; the cure rate was 100% in both groups. After surgery, the length of the vagina in the six-arm mesh group was longer than that of the control group at 6 months and 12 months, respectively ( P < 0.05). The six-arm mesh group had lower PFDI-20 and CRADI-8 scores after surgery than those of the control group at 6 and 12 months, respectively ( P < 0.05). Pelvic floor and rectal dysfunction symptom improvement were superior in the six-arm mesh group compared with the control group. After surgery, the Female Sexual Function Inventory (FSFI) score of the six-arm mesh group was superior to that of the control group at 6 and 12 months, respectively ( P < 0.05). The incidence of complications in the six-arm mesh group was lower than that of the control group ( P < 0.05).

          Conclusion

          The total pelvic floor reconstruction using six-arm mesh has the same healing rate as anteroposterior approach mesh surgery, and it is better than traditional surgery in improving subjective symptoms and reducing postoperative complications.

          Short forms of two condition-specific quality-of-life questionnaires for women with pelvic floor disorders (PFDI-20 and PFIQ-7).

          To develop short forms of 2 valid and reliable condition-specific quality-of-life questionnaires for women with disorders of the pelvic floor including urinary incontinence, pelvic organ prolapse, and fecal incontinence (Pelvic Floor Distress Inventory and Pelvic Floor Impact Questionnaire). Data from the 100 women who contributed to the development and validation of the Pelvic Floor Distress Inventory and Pelvic Floor Impact Questionnaire long forms were used to develop the short-form questionnaires. All subsets regression analysis was used to find the items in each scale that best predicted the scale score on the respective long form. When different items appeared equivalent, a choice was made on item content. After development, the short forms and the Pelvic Floor Distress Inventory and Pelvic Floor Impact Questionnaire long forms were administered preoperatively to 45 women with pelvic floor disorders scheduled to undergo surgery to evaluate the correlation between short and long forms in a second independent population. The short forms were readministered 3 to 6 months postoperatively to assess the responsiveness of the instruments. The short-form version of the Pelvic Floor Distress Inventory has a total of 20 questions and 3 scales (Urinary Distress Inventory, Pelvic Organ Prolapse Distress Inventory, and Colorectal-Anal Distress Inventory). Each short-form scale demonstrates significant correlation with their long-form scales (r=.86, r=.92, and r=.93, respectively, P<.0001). For the Pelvic Floor Impact Questionnaire short form, the previously developed short form for the Incontinence Impact Questionnaire-7 was used as a template. The 7 items identified in the previously developed Incontinence Impact Questionnaire-7 short form correlate highly with the Incontinence Impact Questionnaire long form (r=.96, P<.0001) as well as the long forms of the Colorectal-Anal Impact Questionnaire scale (r=.96, P<.0001) and the Pelvic Organ Prolapse Impact Questionnaire (r=.94, P<.0001). All subsets regression analysis did not identify any items or combination of items that correlated substantially better for any of the 3 scales. The scales of the Pelvic Floor Distress Inventory-20 and Pelvic Floor Impact Questionnaire-7 maintained their excellent correlation to the Pelvic Floor Distress Inventory and Pelvic Floor Impact Questionnaire long forms in the second independent sample (r=.88 to .94 for scales of Pelvic Floor Distress Inventory-20; r=.95 to .96 for scales of Pelvic Floor Impact Questionnaire-7, P<.0001 for all). The test-retest reliability of each scale was good to excellent (intraclass correlation coefficient 0.70 to 0.93, P<.001 for all scales). The scales and summary scores of the Pelvic Floor Distress Inventory-20 and Pelvic Floor Impact Questionnaire-7 demonstrated moderate to excellent responsiveness 3 to 6 months after surgery. The Pelvic Floor Distress Inventory-20 and Pelvic Floor Impact Questionnaire-7 are valid, reliable, and responsive short forms of 2 condition-specific quality-of-life questionnaires for women with pelvic floor disorders.

            Lifetime risk of undergoing surgery for pelvic organ prolapse.

            To investigate the lifetime risk of first-time incident pelvic organ prolapse (POP) surgery with the intention of updating previous risk estimates that have been based on members of managed-care populations. Age-specific incidence rates of first-time prolapse surgery between 1981 and 2005 were calculated based on 44,728-incident cases. We estimated the lifetime risk as the cumulative incidence to age 85 years based on a life-table method and using the most recent cross-sectional incidence rates for the period 2001-2005. Age-standardized rates by calendar year were also calculated to show the secular trend in prolapse surgery. The lifetime risk of surgery for POP in the general female population was 19% based on the most recent cross-sectional rates, a figure higher than the 11-12% reported from U.S. managed-care populations. There is a relatively high likelihood that a woman in Western Australia will undergo surgery for POP during her lifetime. If, as our results suggest, the burden of genital prolapse in general populations is higher than previously thought, there is justification for a stronger evidence base for prevention, early detection and intervention to reduce the personal and societal costs of these gynecological conditions.

              Incidence and management of graft erosion, wound granulation, and dyspareunia following vaginal prolapse repair with graft materials: a systematic review.

              This study describes the incidence, risk factors, and treatments of graft erosion, wound granulation, and dyspareunia as adverse events following vaginal repair of pelvic organ prolapse with non-absorbable synthetic and biologic graft materials. A systematic review in Medline of reports published between 1950 and November 2010 on adverse events after vaginal prolapse repairs using graft materials was carried out. One hundred ten studies reported on erosions with an overall rate, by meta-analysis, of 10.3%, (95% CI, 9.7 - 10.9%; range, 0 - 29.7%; synthetic, 10.3%; biological, 10.1%). Sixteen studies reported on wound granulation for a rate of 7.8%, (95% CI, 6.4 - 9.5%; range, 0 - 19.1%; synthetic, 6.8%; biological, 9.1%). Dyspareunia was described in 70 studies for a rate of 9.1%, (95% CI, 8.2 - 10.0%; range, 0 - 66.7%; synthetic, 8.9%; biological, 9.6%). Erosions, wound granulation, and dyspareunia may occur after vaginal prolapse repair with graft materials, though rates vary widely across studies.
