Definitive abdominal wall closure using a porcine intestinal submucosa biodegradable membrane in pediatric transplantation.

Abstract：

:Abdominal closure in children less than 10 kg following liver or kidney transplantation can be challenging. Excessive pressure attained from a tight closure can result in abdominal compartment syndrome, graft compromise and loss. Concerns over using prosthetic patches are that of infection and dehiscence. We report a series of definitive abdominal wall closure using a biodegradable membrane from porcine intestinal submucosa (Surgisis; Cook Biotech Incorporated, West Lafayette, IN, USA). A prospective collection and follow up of liver and kidney transplant patients weighing less than 10 kg who required abdominal wall augmentation with Surgisis in order to achieve satisfactory closure. There were 10 liver and two renal transplant patients. The average weight of the liver transplant patients was 6.6 kg (5.4-8.5 kg) and the renal 9.8 kg. The average area of Surgisis used was 71.2 cm(2) (25-160 cm(2)) and length of follow up was 15.3 months (1-27 months). Concomitant measures to aid abdominal closure included bilateral recipient nephrectomy for the renal patients and reduction by 33% of the lateral segmental grafts in two liver transplant patients. Delayed closure occurred in all patients except one and the average days to closure from the first surgery was 3.75 days (0-6 days). Following liver transplantation one patient died from multiple organ failure at one month secondary to hemophagocytosis from underlying combined immune deficiency syndrome and one patient with hepatic artery thrombosis was salvaged at re-exploration. There were two wound complications, one patient developed two small sinuses and some skin dehiscence which healed over four months and the second developed a skin sinus following trans-patch liver biopsy which healed in three wk. Both had positive microbial cultures but neither necessitated removal of the graft. There were no incisional hernias. Surgisis is a safe method for facilitating abdominal closure in pediatric transplant patients. It appears to have long-term durability with no incisional hernias on short- and medium-term follow up, and is fairly resistant to infection.
