Native tissue repair and failure risk
Dr. Gebhart: I hear a lot that native tissue repairs fail. Mickey, as you do a lot of vaginal surgery, what are your thoughts? Should you use augmentation of some sort because native tissue fails?
Dr. Karram: There is going to be a failure rate with whatever surgery you do. I think that the failure rate with native tissue is somewhat overstated. I think a lot of that dates back to some of the things that were being promoted by mesh advocates. Initially, there was a lot of cherry-picking of native tissue data in some of those studies to promote the idea that the recurrent prolapse rates were 40% to 80%. We certainly do not see that in our patient population.
Based on our 5-year data, we have a recurrence rate of about 15% and a reoperation rate of less than 10%. That is the best I can quote based on our data. We have not followed patients longer than 5 years.
I can’t do much better than that with an augmentation; even if I get another 5% or 10% better anatomic outcome, that will be at the expense of some erosions and other complications specific to the mesh. I do think that the native tissue failure rate being promoted by a lot of individuals is a higher failure rate than what we are seeing.
Dr. Gebhart: What do you think, Mark?
Dr. Walters: Large cohort studies both at your institution, Mayo Clinic, and ours at the Cleveland Clinic mirror what Dr. Karram said, in that we have a reoperation rate somewhere between 8% and 15%. Of course, we have some failures that are stage 2 failures where patients choose not to have another operation. In general, a 10% or 12% reoperation rate at 5 to 7 years is acceptable.
Native tissue repairs probably fail at the apex a little more than mesh sacrocolpopexy. Mesh sacrocolpopexy, depending on what else you do with that operation, may have more distal vaginal failures, rates like distal rectoceles and more de novo stress urinary incontinence than we probably get with native tissue. I get some failures of the apex with native tissue repairs, but I am okay with using sacrocolpopexy as the second-line therapy in those patients.
Hysteropexy technique and pros and cons
Dr. Gebhart: Is hysteropexy a fad, or is there something to this?
Dr. Ridgeway: I do not think it is a fad. Women do feel strongly about this, and we now have data supporting this choice: randomized controlled trials of hysterectomy and prolapse repair versus hysteropexy with comparable outcomes at the short and medium term.2
The outcomes are similar, but as we said, outcomes for all prolapse repair types are not perfect. We have recurrences with sacrocolpopexy, native tissue repair, and hysteropexy. We need more data on types of hysteropexy and long-term outcomes for uterine preservation.
Dr. Walters: We have been discussing what patients think of their uterus, and some patients have very strong opinions. Some prefer to have a hysterectomy because then they don’t need to worry about cancer or do screening for cancer, and they are very happy with that. Other women with the same kind of prolapse prefer not to have a hysterectomy because philosophically they think they are better off keeping their organs. Since satisfaction is an outcome, it is useful to know what the patient wants and what she thinks about the surgical procedure.
Dr. Gebhart: For hysteropexy, do the data show that suture or a mesh augment provide an advantage one way or the other? Do we know that yet?
Dr. Walters: No, there are not enough studies with suture. There are only a few very good studies with suture hysteropexy, and they are mostly sacrospinous suture hysteropexies. Only a few studies look at mesh hysteropexy (with the Uphold device that was put on hold), or with variations of uterosacral support using strips of mesh, mostly done in other countries.
A point I want to add, if native tissue repairs fail at the apex more, why don’t you just always do sacrocolpopexy? One reason is because it might have a little higher complication rate due to the abdominal access and the fact that you are putting mesh in. If you have, for example, a 4% complication rate with the mesh but you get a better cure rate, those things balance out, and the woman may not be that much better off because of the extra complications. You have to assess the pro and con with each patient to pick what is best for her—either a more durable repair with a mesh or a little safer repair with native tissue.
