Ventral Hernias

Repair of large contaminated ventral hernias is always challenging because of massive loss of muscular and fascial tissues, high risk of surgical infection and recurrence, and contraindication to use of a permanent prosthesis. This study reviewed retrospectively data of 35 patients with contaminated large ventral hernias who received repair using acellular dermal matrix combined with a component separation technique from 2009 to 2011. Twenty-one males and 14 females were identified with a mean age of 45.5 ± 12.5 years and a mean body mass index of 22.5 ± 5.8 kg/m2. Simultaneously, nine patients underwent bowel fistula resection, 13 patients underwent ostomy takedown, five patients underwent recurrent colon cancer dissection, and eight patients underwent infectious permanent mesh removal and wound débridement. Mean defect size was 125.0 ± 23.5 cm2. The aponeurosis of the external oblique muscle was transected and separated from internal oblique muscle to reach abdominal closure. A cellular dermal matrix was placed in an onlay fashion and mean mesh size was 300.0 ± 65.0 cm2. Thirty-five patients had a mean follow-up period of 36.5 ± 12.5 months. Wound bleeding and partial dehiscence occurred at 36 hours post-operatively. Five patients reported abdominal wall pain during the first postoperative month. Five patients developed surgical site infection. Four patients were detected to develop seroma with volume more than 20 mL by B-ultrasound examination. No recurrence and chronic foreign body sensation were followed up. Use of acellular dermal matrix combined with a component separation technique is safe and efficient management for repair of contaminated large ventral hernia, in which permanent prosthesis placement is contraindicated.

Background The optimal material for reinforcement of complex abdominal ventral hernia repair (VHR) remains controversial. Biologic prostheses such as porcine and bovine acellular dermal matrix (PADM/BADM) have shown favorable results, but few head-to-head comparisons between the two types exist. We sought to provide such a comparison. Methods We performed a retrospective cohort study comparing 40 consecutive patients who underwent open component separation (CS/VHR) with PADM reinforcement to 39 consecutive patients who underwent open CS/VHR with BADM reinforcement at our institution. Patient characteristics, outcomes, complications, reoperations, and hernia recurrences were obtained by chart review. Fisher’s exact and t-test analyses compared patient characteristics and outcomes between the 2 cohorts. Statistical significance was set as P < .05. Results Patient groups did not differ significantly in race (P=.36), age (P=.8), BMI (P=.34), sex (P=.09), steroid usage (p-1.00), COPD (P=.43), number of previous abdominal operations (P=.66), and duration of follow-up (P=.65). There were significantly more smokers in the PADM group (37.5% vs 12.8%, P=.01). Mean defect size was significantly greater in the PADM group (372.5 cm2 vs 292. cm2 in the BADM group, P=.001) as was the number of Ventral Hernia Working Group (VHWG) grade III/IV hernias (65.0% vs 38.4%, P=.02). Recurrence rates were lower in the BADM group, (12.5% vs 5.1%, P=.26), as was recurrence or complications requiring reoperation (17.5% vs 5.1%, P=.15). Postoperative wound events were also significantly lower in the BADM group (30.0% vs 2.6%, P=.001). Conclusions In our series, CS/BADM was associated with significantly fewer wound complications. Recurrences and complications requiring reoperation were also fewer, which trended toward but did not reach statistical significance, presumably due to the small sample size. These findings indicating superiority of BADM over PADM are potentially confounded by the higher percentage of smokers, the larger mean defect size, and the higher number of VHWG III/IV patients in the PADM group. Further prospective study of these findings is warranted.

AbstractAcellular dermal matrices are biological materials of porcine, bovine, or human origin used as scaffold for reconstructive purpose in plastic surgery; these materials are well-tolerated and safely integrated in host tissues without causing resorption, contracture, and encapsulation thanks to their low antigenicity.Recently, human acellular dermal matrix has been used as a filler in breast-conserving surgery to improve aesthetic results. Adequate knowledge of biomaterials properties, appropriate skill, and careful compliance with some specific recommendations are mandatory in order to optimize outcomes and obtain a work of success.
