DENVER – Using absorbable polydioxanone suture during laparoscopic sacrocolpopexy was associated with a mesh erosion rate of just 1.6%, according to a single-center, 1-year prospective study of 64 patients.
That is substantially less than typical erosion rates of about 5% when permanent suture is used, Danielle Taylor, DO, of Akron (Ohio ) General Medical Center said at Pelvic Floor Disorders Week sponsored by the American Urogynecologic Society.
The researchers observed no anatomic failures or suture extrusions, and patients reported significant postoperative improvements on several validated measures of quality of life.
“Larger samples and longer follow-up may be needed,” said Dr. Taylor. “But our study suggests that permanent, nondissolving suture material may not be necessary for sacrocolpopexy.”
Sacrocolpopexy with mesh usually involves using nonabsorbable suture to attach its anterior and posterior arms to the vaginal mucosa. Instead, Dr. Taylor and colleagues used 90-day delayed absorbable 2.0 V-Loc (Covidien) suture during laparoscopic sacrocolpopexy for patients with baseline Pelvic Organ Prolapse Quantification (POP-Q) scores of at least 2 and symptomatic uterovaginal prolapse.
Two permanent Gore-Tex sutures were also placed at the apex of the cervix in each of the 64 patients, said Dr. Taylor, a urogynecology fellow at the University of Massachusetts, Worcester, who worked on the study as a resident at the Cleveland Clinic Akron General, in Ohio. She and her colleagues rechecked patients at postoperative weeks 2 and 6, and at months 6 and 12. They lost two patients to follow-up, both after week 2.
At baseline, 37 patients (58%) were in stage II pelvic organ prolapse, 27% were in stage III, and 14% were in stage IV. At 6 months after surgery, 85% had no detectable prolapse, 8% had stage I, and 6% had stage II. At 1 year, 82% remained in pelvic organ prolapse stage 0 and the rest were in stage I or II. All stage II patients remained asymptomatic, Dr. Taylor said.
At baseline, the median value for POP-Q point C was -3 (range, –8 to +6). At 6 months and 1 year later, the median value had improved to –8, and patients ranged between –10 and –8.
Quality of life surveys of 54 patients reflected these outcomes, Dr. Taylor said. A year after surgery, average scores on the Pelvic Floor Distress Index (PFDI) dropped by 67 points, from 103 to 35 (P less than .0001). Likewise, average scores on the Pelvic Floor Impact Questionnaire (PFIQ) dropped by 29 points (P less than .0001), and scores on the Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire (PISQ) indicated a significant decrease in the effects of pelvic organ prolapse on sexual functioning (P = .008).
In addition to a single case of mesh erosion, one patient developed postoperative ileus and one experienced small bowel obstruction, both of which resolved, Dr. Taylor reported. The researchers aim to continue the study with longer follow-up intervals and detailed analyses of postoperative pain.
