Intense Inflammatory Reaction With Porcine Small Intestine Submucosa Pubovaginal Sling or Tape for Stress Urinary Incontinence

Abstract

To report on the intense local inflammatory reactions in patients undergoing pubovaginal sling or tape using a small intestinal submucosa graft. A case series of such inflammatory complications is presented. We performed 16 standard pubovaginal sling or tension-free tape procedures for stress urinary incontinence, using the Cook 4-ply Stratasis or 8-ply Stratasis-TF system. The diagnosis had been confirmed by the history, physical examination, and urodynamic study findings. Of the 16 patients, 5 (31.3%) had intense suprapubic pain after surgery. One patient had induration of the mons pubis that required surgical drainage. Another patient had vaginal inflammation, with expulsion of graft material. Other patients had intense rectus sheath inflammation, as confirmed on computed tomography, that resolved with conservative care. Previous case reports of inflammatory complications of small intestinal submucosa were confirmed in 31% of our patients. We have ceased using this product pending additional investigations or reformulation of the graft material.
