The objective of this study is to assess pain that occurs following hernia repair that is related to mesh fixation. The study is designed to see if there is any difference in pain after surgery between absorbable and permanent methods of mesh fixation in inguinal and ventral hernia repair.

Condition Intervention Phase
Hernia, Inguinal
Hernia, Ventral
Device: AbsorbaTack
Device: ProTack
Phase 4

Primary Outcome Measures:
  • Postoperative Pain [ Time Frame: Discharge, Month 1, Month 6, Month 12 ] [ Designated as safety issue: No ]

    Pain Intensity Numeric Rating Scale (PI-NRS) - change from baseline. Treatments analyzed within inguinal arm and within ventral arm.

    Scale is 0 - 10 with 0 being "no pain" and 10 being "worst pain imaginable".

  • Safety for Laparoscopic Hernia Repair as Measured by Number of Patients Experiencing Device Related Events [ Time Frame: One year ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Quality of Life [ Time Frame: Pre-op, Month 1, Month 6, 1 year ] [ Designated as safety issue: No ]

    Quality of life as measured by the SF-12 which is a multipurpose short form survey with 12 questions. The questions were combined, scored, and weighted to create a scale that provide glimpses into physical functioning and overall health-related-quality of life.

    The Physical Composite Score was computed using the scores of twelve questions and range from 0 to 100, where a zero score indicates the lowest level of health measured by the scales and 100 indicates the highest level of health.

  • Hernia Recurrence [ Time Frame: Discharge, 1 Month, 6 Month, 1 year ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Active Comparator: A Device: AbsorbaTack
Comparison of different devices for mesh fixation. This intervention arm has absorbable tacks as the method of hernia mesh fixation. Application is during hernia repair and tacks will essentially absorb within the body after 1 year.
Active Comparator: B Device: ProTack
Comparison of different devices for mesh fixation. This intervention is a permanent tack for hernia mesh fixation. Application is during hernia repair and the tacks will remain in the body.
