Objective: The ideal implant material for the surgical repair of pelvic organ prolapse in women is yet to be found. This retrospective study aims to evaluate a porcine small intestinal submucosa (SIS) graft (Surgisis™). Study design: We reviewed the medical records of women that were operated upon for pelvic organ prolapse using implantation of SIS graft and we examined the short-term complications and recurrence rates. Results: A total of 155 surgical procedures were reviewed. SIS graft was placed in the anterior, posterior and middle compartments in 93 (60%), 71 (45.8%) and 13 (8.4%) cases, respectively. At three-month follow-up, 22.6% of anterior graft repairs displayed anatomical recurrence (POP-Q stage ≥ 2), compared to 4.8% of posterior and none of the middle compartment graft repairs. During the three postoperative months, 56% of the women were recorded with complications, mostly urinary retention (19%) and pain (12%). The incidence of grade III complications was 5.3%. Persistent complications at three months were observed in 28% of all cases. Logistic regression analysis showed that previous prolapse surgery at the same compartment was a significant predictor for recurrence of prolapse after SIS graft application, whereas lower age, smoking and longer duration of surgery were significant predictors for the development of complications. Younger women had higher risk of developing pain postoperatively. Conclusion: Pain and urinary tract symptoms hold a central position in the complications profile of SIS graft-augmented prolapse surgery. The relatively high recurrence rates do not suggest a clear benefit from SIS graft use.
