In 7-year study, failure rate for pelvic organ

TUESDAY, May 14 (HealthDay News) -- The success of a common surgery for pelvic organ prolapse -- a painful and distressing condition affecting many women -- lessens over time, according to a new study.

Abdominal sacrocolpopexy is a procedure used to relieve the problem. It involves stitching a piece of mesh on the top of the vagina and attaching it to a strong ligament from the back of the pelvic bone. This surgery helps to support the pelvic organs.

But the new study found that with each passing year, the rate of pelvic organ prolapse surgery failure increased. The rate of mesh erosion (the primary material used to provide support) reached 10.5 percent by seven years after surgery.

The study also found that the risk of urinary incontinence rose with each year after the surgery.

"This is the longest follow-up of a common operation for women with pelvic organ prolapse. We found that pelvic organ prolapse and urinary incontinence rates increased gradually over follow-up," said study author Dr. Linda Brubaker, a professor of obstetrics and gynecology and urology at Loyola University Medical Center.

Even though surgeons might define a procedure as a failure, many of the patients did not. Only about 17 percent of women had additional pelvic floor surgeries, according to the study.

Pelvic organ prolapse leads to surgery in 7 percent to 19 percent of women, according to study background information. Normally, muscles, ligaments and connective tissue keep all of the pelvic organs where they're supposed to be. But, weakness or tears in these supportive tissues can allow pelvic organs, such as the uterus and vagina, to protrude through the vaginal opening.

This can lead to problems with pelvic organs, according to the American Urogynecologic Society. For example, if the bowel is protruding, constipation or fecal incontinence can result. If the bladder is affected, urinary incontinence may occur.

As to why these surgeries might fail, Brubaker said, "surgeries don't stop time. Women continue to age and the underlying biology continues. Patients may gain weight, too," added Brubaker, who is also dean of the Loyola University Chicago Stritch School of Medicine.

Results of the study are published in the May 15 issue of the Journal of the American Medical Association.

Each year, as many as 225,000 American women have surgery for pelvic organ prolapse, the study authors noted. However, very little long-term follow-up data is available on the success of these procedures, Brubaker said. Most studies only follow women for two years.

The current study included seven years of follow-up. Abdominal sacrocolpopexy isn't the only procedure available for pelvic organ prolapse, but it is commonly used. And, in more recent years, the surgery is being done laparoscopically, so it's less invasive.
