OBJECTIVE: To estimate prevalence, risk factors, and etiology of post-Pfannenstiel pain syndromes. METHODS: All women (n=866) with a Pfannenstiel incision for cesarean delivery or abdominal hysterectomy performed between January 2003 and December 2004 received a questionnaire evaluating pain located in the Pfannenstiel region. A multivariate logistic regression analysis was done to determine predictors for chronic pain development. Patients with moderate or severe pain were interviewed and underwent a physical examination. RESULTS: The response rate was 80% (690 of 866 patients). Subsequent to a follow-up after 2 years, one third (223 of 690) experienced chronic pain at the incision site. Moderate or severe pain was reported by 7%, and in 8.9% of respondents, pain impaired daily activities. Numbness, recurrent Pfannenstiel surgery, and emergency caesarean delivery were significant predictors of chronic pain. Nerve entrapment was present in over half the examined patients with moderate-to-severe pain (17 of 32). CONCLUSION: Chronic pain occurs commonly after a Pfannenstiel incision. Nerve entrapment was found to be a frequent cause of moderate-to-severe pain.
