"We've known for the past five to six years that global endometrial ablation devices are very effective," says Mayo Clinic gynecologic surgeon Abimbola Famuyide, M.B.B.S., one of the study's authors. "But some physicians have observed that up to 30 percent of patients may require additional treatment five years and beyond after undergoing ablation."
Undergoing a hysterectomy or another treatment following ablation to achieve permanent symptom relief can be costly and inconvenient for patients. Mayo researchers note that much of the medical research citing failure rates associated with GEA had relatively small study populations and differing definitions of what constituted failure. To establish more precise, population-derived data measuring how many women do not experience permanent symptom relief following GEA, they studied the medical records of approximately 816 women who underwent ablation from Jan. 1, 1998, through Dec. 31, 2005.
"We found that only 16 percent of our subjects required hysterectomy to treat excessive bleeding five years after ablation. That is nearly half of what has generally been reported in the literature to date," explains Dr. Famuyide.
Mayo researchers hypothesized that the low failure rate they observed might mean that their study patients received counseling about realistic expectations for symptom relief. "For example, patients who are seeking complete cessation of menstrual bleeding after GEA are more likely to undergo hysterectomy later to treat bleeding symptoms of any severity," says Dr. Famuyide.
Mayo Clinic research data also showed that patients under age 45, patients who have undergone tubal ligation (a procedure to prevent pregnancy), and patients who experienced debilitating menstrual pain before undergoing GEA were less likely to experience permanent symptom relief following ablation.
