Use of biological prostheses in transplant patients with incisional hernias Preliminary experience.
ABSTRACT AIM: The use of synthetic mesh in transplant patients is still under debate. In this paper the authors report their preliminary experience on biological prosthesis for surgical treatment of incisional hernias in transplant patients. MATERIAL OF STUDY: Between 2009-2010, 10 patients with incisional hernia underwent surgery using a biological prosthesis (porcine dermis collagen). All patients were transplanted: 9 kidney transplants and 1 liver transplant. RESULTS: In all patients postoperative course was uneventful and were not observed complications related to surgery, kind of prosthesis or transplanted organs. At follow up, laparoplasty was associated with good functional outcome. DISCUSSION: Transplant patients are at risk for use of synthetic prostheses, as immunosuppressed. In our preliminary experience biological prostheses compared to synthetic ones showed a greater ability to integrate into tissues, to resist bacterial colonization and to reduce cytotoxic or allergenic reactions, providing similar functional results. Moreover it must be added that biological prostheses did not require reductions/suspensions of immunosuppressive therapy and resulted to be versatile. All these features are particularly sought in incisional hernias surgery of transplanted patients. CONCLUSIONS: Surgery of incisional hernias in transplanted patients requires a prosthesis with characteristics as close as possible to the ideal one and, in this sense, biological prostheses would seem to outweigh synthetic ones. In our experience, biological prostheses have shown to be safe, effective and reliable; therefore they seem to be able to open new horizons in the treatment of wall defects in this group of patients.

ABSTRACT: The risk of fascial dehiscence, wound infection and incisional hernias in organ recipients is higher. Retrospective analysis of our departments database, checking the last 12 years (2000-2012), and of the literature (1966-2012) were conducted. In our database we found seven patients: five liver (71.4 %), one kidney (14.3 %), one multivisceral (14.3 %); five males (71.4 %), two females (28.6 %). Five (71.4 %) were operated in urgency setting and two in ordinary setting (28.6 %). The mean/median number of laparotomies before the incisional hernia is of 2.1/1 (range 1-5). In five patients swine intestinal submucosa (71.4 %) have been used and in two porcine dermal collagen (28.6 %). The mean/median age was 48.3/52 years (range 18-61). The mean/median body mass index was 26.7/27 (range 19-34). The mean/median for follow-up after intervention was 40.1/33 months (range 50-21). Recurrence rate was 14.3 %. Complication rate was 28.6 %. Adding the present report, the literature reports 70 cases. 20 % of prosthesis have been implanted inlay, 25.7 % underlay, in 5.7 % intraperitoneal and in 48.6 % were not specified. The mean age ranges from 0.7 to 48.3 years. Kidney, liver, pancreas, bowel and multivisceral transplant are reported. Porcine dermal collagen has been implanted in 24.3 %, human dermal collagen in 51.4 % and swine intestinal submucosa in 24.3 %. The immunosuppression regimens comprehend variable associations of tacrolimus, steroids, mycophenolate mofetil, sirolimus, thymoglobulin, azathioprine/basiliximab and daclizumab. The mean follow-up is 16.2 months. The mean complication rate is 9.4 %. Biological prosthesis seems to be useful and safe in abdominal wall repair surgery in transplanted patients.Updates in surgery. 05/2013; 65(3).
