Does type of mesh used have an impact on outcomes in laparoscopic inguinal hernia?

Background: Theoretically, a lighter and softer mesh may decrease nerve entrapment and chronic pain by creating less fibrosis and mesh contracture in laparoscopic inguinal hernia repair.

Methods: We performed a telephone survey of patients who underwent laparoscopic inguinal hernia surgery between 2001 and 2007. We recorded patient responses for chronic pain, foreign body sensation, recurrence, satisfaction, and return to work, and then studied the effect of type of mesh (polypropylene vs polyester) on these factors.
