ABSTRACT The role of acellular dermal matrix (ADM) in abdominal wall reconstruction (AWR) is unclear. The aim of this study was to review the management, complications, and long-term outcomes of AWR using ADM in a large surgical cohort.
Retrospective chart review of patients undergoing AWR using ADM from 2004 to 2007 was performed. Demographic data, comorbidities, complications, and long-term outcomes were collected.
There were 77 cases in 68 patients with mean age of 61.1 +/- 1.4 years. The most common indication was infected fascia (n = 19 [25%]). Wound closure was achieved in 75% of the cases via primary (n = 26 [45%]), secondary intention (n = 17 [29%]), or skin graft (n = 15 [26%]). Nonprimary closure was achieved in 5.7 +/- .7 months. There were 32 perioperative (39%) and 33 long-term (43%) complications. Over a mean follow-up period of 13.2 +/- 1.5 months, the hernia recurrence rate was 27% (n = 21).
Although ADM is a viable option in AWR, the high hernia recurrence rate warrants a continued search for alternative biologic materials to improve outcomes.

    ABSTRACT: Ventral hernia repair (VHR) continues to be a challenge for surgeons. Poor long-term durability of the commonly-used human acellular dermal matrix (HADM) grafts often results in VHR failure and reherniation. We hypothesized that fiber-reinforcement will improve the mechanical properties of HADM grafts and maintain these properties after enzymatic degradation. We designed a reinforced HADM (r-HADM) graft comprised of HADM and a small amount (~10wt% or 56g/m(2)) of 2-0 monofilament polypropylene. We evaluated the failure and fatigue biomechanics of r-HADM grafts and HADM controls, before and after 8h of in vitro enzymatic degradation, in ball-burst and planar biaxial testing modes (n=6-11/group/test). Fiber-reinforcement improved time-zero failure properties of HADM. While enzymatic degradation resulted in a significant reduction in nearly all mechanical properties and frequent premature failure of HADM, key sub-failure parameters and cyclic dilatational strain were maintained in r-HADM, with no sample having premature failure. These data show that fiber-reinforcement improves biomechanical properties and imparts mechanical durability to r-HADM during enzymatic degradation. Our findings suggest that fiber-reinforcement may be a strategy to mitigate the loss of HADM graft mechanical properties after in vivo implantation, and thereby limit VHR bulging and improve outcomes.

    ABSTRACT: This retrospective comparative study analyzes the outcome of patients affected by incisional hernia in potentially contaminated or contaminated field, treated by three operative techniques. 152 patients (62 M:90 F; mean age 65 ± 14 years) underwent incisional hernia repair (January 2002-January 2012) in complicated settings. Criteria of inclusion in the study were represented by the following causes of admission: mesh rejection/infection, obstruction without gangrene but with possible peritoneal bacterial translocation, obstruction with gangrene, enterocutaneous fistula or simultaneous presence of ileo- or colostomy. The patients were divided into three groups: A (n = 76), treated with primary closure technique; B and C (n = 38 each), with reinforcement by synthetic or pericardium bovine mesh (Tutomesh(®)), respectively. The prosthetic groups were divided into Onlay and Sublay subgroups. Significant decreases in C vs A were observed for wound infection (3 vs 37 %) and recurrence (0 vs 14 %), and in C vs B for wound infection (3 vs 53 %), seroma (0 vs 34 %) and recurrence (0 vs 16 %). Patients with concomitant bowel resection (BR) (43 %) showed (all P < 0.05) an increase of overall morbidity (55 vs 33 %) and wound infection rate (42 vs 24 %) compared to cases without BR. Morbidity presented no significant differences in C-Onlay or Sublay subgroups. B-Sublay subgroup has (all P < 0.05) lower overall morbidity (20 vs 75 %), wound infection (10 vs 68 %) and seroma (0 vs 46 %) than B-Onlay. The pericardium bovine patch seems to be safe and effective to successfully repair ventral hernia in potentially contaminated operative fields, especially in association with bowel resection.

    ABSTRACT: Prosthetic implants are frequently used for breast augmentation and breast reconstruction following mastectomy. Unfortunately, long-term aesthetic results of prosthetic breast restoration may be hindered by complications such as rippling, capsular contracture, and implant malposition. The advent of use of acellular dermal matrices has greatly improved the outcomes of prosthetic breast reconstruction. We describe a case of rippling deformity of breast that was treated using an acellular dermal matrix product, AlloMax. The patient presented with visible rippling of bilateral prosthetic breast implants as well as significant asymmetry of the breasts after multiple excisional biopsies for right breast ductal carcinoma in situ. A 6 × 10 cm piece of AlloMax was placed on the medial aspect of each breast between the implant and the skin flap. Follow-up was performed at 1 week, 3 months, and 1 year following the procedure. The patient recovered well from the surgery and there were no complications. At her first postoperative follow-up the patient was extremely satisfied with the result. At her 3-month and 1-year follow-up she had no recurrence of her previous deformity and no new deformity.
