Are women with advanced pelvic organ prolapse treated by open mesh sacrocolpopexy at risk of secondary incisional hernia?

Introduction: Our purpose was to determine whether vaginal hernia is a predisposing factor for incisional hernia (IH) in a cohort of women with symptomatic pelvic organ prolapse (POP) who underwent corrective repair by open mesh sacrocolpopexy (MSC) and had long-term follow-up to determine their rate of subsequent IH.

Methods: Following IRB approval, the charts of women entered into a longitudinal database and who underwent open MSC at a tertiary institution were reviewed. Data collected included demographics, MSC and IH details, and long-term outcome. Patients were excluded if the follow-up after MSC was < 1 year. Data were reviewed by a neutral investigator who was not involved in patient care (FA).

Results: From 1999 to 2012, 75 of 88 women met inclusion criteria, with mean follow-up of 65 (48-84) months. Thirteen were either lost to follow-up or had follow-up < 1 year. Seven women underwent symptomatic IH repair, with a mean onset of IH diagnosis after MSC at 18 (range 8-72) months. Five repairs were done via an open approach, and two were repaired laparoscopically. No IH recurrence was noted at a mean of 41 (range 14-75) months after IH repair. No risk factors were identified in the IH group compared with those who did not form a secondary IH.

Conclusions: In this longitudinal series, IH after open MSC occurred in 9.3%, a rate comparable with that reported in women undergoing abdominal procedures through midline or Pfannenstiel incisions.
