Brief Summary:
This trial is being conducted to evaluate the efficacy of Phasix™ Mesh implantation at the time of midline fascial closure compared to primary suture closure in preventing a subsequent incisional hernia in subjects at risk for incisional hernia after open midline laparotomy surgery.

Condition or disease Intervention/treatment Phase
Open Midline Laparotomy Device: Phasix™ Mesh Not Applicable

Detailed Description:
Subjects will be randomized (1:1) to one of the two treatment groups in the operating room after fascial closure.

Arm Intervention/treatment
Experimental: Phasix™ Mesh
Prophylactic onlay placement of mesh.
Device: Phasix™ Mesh
Phasix™ Mesh is a resorbable mesh prepared from Poly-4-hydroxybutyrate (P4HB).

No Intervention: Primary Suture Closure
Standard Fascial closure.

Primary Outcome Measures :
  1. Rate of Incisional Hernia [ Time Frame: 36-Months ]
    The primary endpoint of the trial is the occurrence of incisional hernia in each treatment group (Phasix™ Mesh or Control Group)

Secondary Outcome Measures :
  1. Rate of Incisional Hernia [ Time Frame: 60-Months ]
    Rate of incisional hernia at each follow up time point

  2. Rate of Device-related Adverse Events (AEs) [ Time Frame: 60-Months ]
    Rate of Device-related Adverse Events (AEs)

  3. Length of surgical procedure in minutes [ Time Frame: Study Day 0 ]
    Length of surgical procedure in minutes

  4. Length of time for wound closure in minutes [ Time Frame: Study Day 0 ]
    Length of time for wound closure in minutes

  5. Length of hospital stay in days [ Time Frame: Through hospital stay, typically 3 days ]
    Length of hospital stay in days

  6. Quality of Life: Optum Short Form Survey 12 Item Version 2 (SF-12v2®) [ Time Frame: 60-Months ]
    Health-related quality of life will be measured using the Optum SF-12v2. The questionnaire consists of 12 items weighted and summed to provide physical and mental health scores from the subject's perspective (PCS and MCS). The two composite scores are computed using the scores on twelve questions that range from 0 to 100, with higher score indicating better quality of life.

  7. Quality of Life: EuroQoL-5 Dimensions-3 Level (EQ-5D-3L©) [ Time Frame: 60-months ]
    EuroQoL-Five Dimensions questionnaire-using Three Levels EQ-5D-3L is a standardized instrument for measuring generic health status. It consists of two components; health status description and evaluation. The health status is measured in terms of five dimensions (5D); mobility, self-care, usual activities, pain/discomfort, and anxiety/depression; each dimension ranging from 1-3. From these five dimensions, EQ-5D index is calculated, having a value between 0-1. The evaluation part involves visual analogue scale, asking the subject to mark health status on the day of the interview on a 20 cm vertical scale with end points of 0 and 100. Zero corresponds to " the worst health you can imagine", and hundred corresponds to "the best health you can imagine".
