Anchorsure Versus Capio for Sacrospinous Ligament Fixation

January 18, 2023 updated by: Wake Forest University Health Sciences

Randomized Trial Comparing Anchorsure® Suture Anchoring System and the CapioTM Slim Suture Capturing Device for Sacrospinous Ligament Suspension.

Sacrospinous ligament fixation is a common method of repairing apical support for pelvic organ prolapse but it currently suffers from a high rate of postoperative buttock and posterior thigh pain. Anchorsure® is a relatively new FDA-approved device that uses an anchor instead of the widely-used suture capturing mechanism to perform sacrospinous ligament fixation. The study hypothesis is that Anchorsure® will reduce the degree and rate of buttock and posterior thigh pain compared to the widely used Capio™ Slim suturing capturing Device.

Detailed Description

Sacrospinous ligament fixation is a common method of repairing apical support for pelvic organ prolapse but it currently suffers from a high rate of postoperative buttock and posterior thigh pain. Rates of buttock and thigh pain 6 weeks after sacrospinous ligament fixation with the widely used Capio™ Slim device (Boston Scientific) are about 15-16% with immediate postoperative pain occurring in 55-84% of patients. This study is a randomized controlled single-blind study with the primary goal of investigating if there is an improvement in the intensity and rate of buttock and posterior thigh pain 1 day, 7 days, 6 weeks, and minimum 12 months after sacrospinous ligament fixation with a new device, the Anchorsure® Suture Anchoring System (Neomedic) compared to the widely utilized Capio™ Slim (Boston Scientific) device. 60 patients will be enrolled to undergo sacrospinous ligament fixation for treatment of pelvic organ prolapse. The patients will be randomized into two study groups; one will have sacrospinous ligament fixation using the Capio™ Slim device and the other with the Anchorsure® device. The patient's pain will be recorded via the numerical rating scale (NRS), a validated pain evaluation tool. The study is powered to detect a 2.5 point difference in pain between the two groups, a value that has been shown in studies to be clinically significant to acute pain patients. Secondary outcomes of surgeon satisfaction and efficiency with the devices will be assessed via surgeon questionnaires.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Buttock and Posterior Thigh Pain
Time Frame: postoperative 12 month
This will be assessed using the numeric rating scale (NRS). The score is 0-10, with higher scores denoting a greater degree of pain.
postoperative 12 month

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
POP-Q Stage Score
Time Frame: at 12 MONTHS
The stage is assigned as follows: 0 if there is no prolapse at all, 1 if there is prolapse but the leading point is not within 1cm of the hymen, 2 if the leading point is within 1 cm of the hymen (from 1cm within the hymen to 1cm beyond the hymen), 3 if the leading point is more than 1cm from the hymen but less than 2cm from being completely prolapsed, and 4 if the leading point is within 2cm of being complete prolapsed. Therefore higher POP-Q stages correlate to a worse degree of prolapse than lower POP-Q stages.
at 12 MONTHS
Change in Pelvic Flore Disability Index - 20 (PFDI-20) Scores From Baseline to 12 Months
Time Frame: Baseline and Month 12

Symptomatic success was assessed by the pelvic floor disability index (PFDI-20) questionnaire. The PFDI-20 has 20 items within 3 sub-scales of symptoms (total of 20 items). Each item produces a response of 0 to 4, the average response in each sub-scale is multiplied by 25 to obtain the sub-scale score (range 0 to 100). The total score is the sum of the three sub-scale scores with a range of 0-300. Higher value for a time-point score indicates a greater degree of symptom bother.

The difference in scores across the study time-points was calculated by subtracting the total score at baseline from the score at 12 months post-operation. A negative value for the difference in scores from baseline to 12 months indicates symptom improvement, where the more negative the difference in score is the greater the improvement in symptoms.

Baseline and Month 12
Change in Symptomatic Success - PFIQ-7 Scores
Time Frame: Baseline and Month 12

Symptomatic success will be assessed by the Pelvic Floor Impact Questionnaire - 7 (PFIQ-7). The PFIQ-7 has 7 items for each of 3 sub-scales (total of 21 items). Each item produces a response of 0 to 3, the average response in each sub-scale is multiplied by 100/3 to obtain the total scale score (range 0 to 100). The total score is the sum of the three sub-scale scores with a range of 0-300. Higher value for a time-point score indicates a greater degree of symptom bother.

The difference in scores across the study time-points was calculated by subtracting the total score at baseline from the score at 12 months post-operation. A negative value for the difference in scores from baseline to 12 months indicates symptom improvement, where the more negative the difference in score is the greater the improvement in symptoms.
