Brief summary

This is a prospective, multicenter, interventional, observational, open label, single arm, longitudinal evaluation of ventral incisional hernia repair using LTM in contaminated or infected sites. Three interim analyses are planned to examine the incidence of surgical site events, postoperative resumption of activities and hernia recurrence.

Inclusion criteria

* is an adult ≥18 years old. * has need of open abdominal incisional repair of a contaminated or infected site * has an estimated hernia size of \>9cm2 by physical exam

Exclusion criteria

* has a nidus of chronic colonization * has a systemic infection at the time of repair. * has chronic conditions: hepatic cirrhosis (w/ or w/o ascites); renal failure w/ hemo- or peritoneal dialysis; incomplete resection of malignant disease; or defined collagen disorder. * requires chronic immunosuppressive therapy, including steroids or cytotoxic agents. * is bedridden or otherwise non-ambulatory. * is ASA Class 4 or 5. * has a BMI \>40. * has conditions that would adversely affect subject safety, as per product labeling, including sensitivities to pork or porcine products.

MeasureTime frameDescription
Incidence of Wound EventsPostoperatively up to 24 monthsWound Events are defined as those events which occurred in the area of the hernia repair and the repair site, including seroma, hematoma, dehiscence, infection, abscess, fistula, and re-herniation.

Secondary

MeasureTime frameDescription
Activities Assessment Scale (AAS)BaselineThe AAS includes 13 items covering a broad sample of sedentary, movement-related and graded-intensity physical activities. Respondents are asked to rate the degree of difficulty performing each of these activities in the previous 24 hours on a 5-point scale from No difficulty to Not able to do it. The AAS has three subscales: sedentary activities (items 1-4); ambulatory activities (items 6-8); work/exercise activities (items 11-13). The AAS total and subscale scores are numerically transformed to produce a range of 0-100, with higher values indicating greater functional activity.

Incidence of Wound Events

Wound Events are defined as those events which occurred in the area of the hernia repair and the repair site, including seroma, hematoma, dehiscence, infection, abscess, fistula, and re-herniation.

Time frame: Postoperatively up to 24 months

Population: 80 patients were enrolled and received Strattice Reconstructive Tissue Matrix to support the repair and were included in the Intent to Treat (ITT) population.
