Staged abdominal closure after small bowel or multivisceral transplantation.
ABSTRACT Following paediatric SBMT, size discrepancy between the recipient's abdomen and the graft may lead to ACS, graft dysfunction, and death. We report our experience with SAC in these patients. Between 04/1993 and 03/2009, 57 children underwent 62 SBMTs. When abdominal wall tension seemed excessive for safe PAC, SAC was performed, using a Silastic® sheet and a vacuum occlusive dressing. Transplantations with SAC (23 combined liver and small bowel [CLB]) were compared with those with PAC [14 ISB and 25 CLB]. Indications for transplantation, preoperative status (after stratification for ISB/CLB transplants), age at transplantation, donor-to-recipient weight ratio, reduction in bowel and/or liver, and incidence of wound complications were not different in both groups. Post-operative intubation, stay in intensive care unit, and hospital stay were prolonged after SAC. Two deaths were related to ACS after PAC, none after SAC. Since 2000, one-yr patient survival is 73% after ISB transplantation and 57% vs. 75% after CLB transplantation with PAC vs. SAC, respectively (NS). SAC safely reduces severe ACS after paediatric SBMT and can be combined with graft reduction for transplantation of small recipients.

ABSTRACT: Abdominal wall closure after intestinal transplantation (ITX) or multivisceral transplantation (MVTX) is challenging because of the loss of abdominal domain and wall elasticity as a result of previous operations and donor-to-recipient weight and height mismatch. We report on abdominal wall closure management in 30 ITX and MVTX recipients. In 60% of patients (n = 18), a primary abdominal closure (PAC) was achieved, in 40% (n = 12) a staged closure (SAC) was necessary. Patients with PAC had undergone less pretransplant operations and required less posttransplant relaparotomies. They were mainly ITX recipients or more abdominal domain because of a longer intestinal remnant. A literature review revealed different strategies to overcome a failed primary closure. They focus on graft reduction or an enlargement of the abdominal domain. The latter includes temporary coverage with prosthetic materials for SAC. Definite abdominal closure is achieved by skin only closure, or by using acellular dermal matrix, rotational flaps, rectus muscle fascia or abdominal wall grafts. Abdominal wall reconstruction after ITX/MVTX is commonly demanded and can be conducted by different strategies. The technique should be easy to use in a timely manner and should prevent abdominal infections, intestinal fistulation, incisional hernias, and wound dehiscence.Current opinion in organ transplantation 04/2012; 17(3):258-67.

ABSTRACT: Intestinal transplantation is known to be associated with a high risk of early complications and mortality. We analyzed prospective data of 51 primary small bowel transplantations from December 1999 to August 2009 and identified perioperative factors that impact on early mortality (≤6 months after transplantation) after isolated intestinal (IITx; n=12) and combined liver-intestinal transplantation (CLITx group; n=39). Ten patients died during the first 6 months after transplantation, all of them in CLITx group (n=10/51, 19%). Multivariate analyses demonstrated intraoperative red blood cell transfusion greater than 70 mL/kg (P=0.019, odds ratio [OR]=13.79) and base excess 30-min after reperfusion less than -16 (P=0.001, OR=14.05), thrombocytopenia (<50,000 per dL) between day 1 and day 15 after transplantation (P=0.047, OR=5.22), and occurrence of vascular complications (P=0.003, OR=8.96) during the posttransplantation period as predictors of early mortality in CLITx group. Risk of mortality at 6 months after intestinal transplantation increased when the liver is included as combined graft. Strategies to reduce mortality such as refining selection for transplantation and early referral before the development of liver failure should be a priority.Transplantation 09/2012; 94(8):859-65.

ABSTRACT: The improvement of outcomes in intestinal transplantation (ITx) over the last two decades has been made possible through standardization in surgical techniques, improvements in immunosuppressive and induction protocols, and post-operative patient care. From a surgical technical point of view, all different types of small bowel containing transplants can be categorized into three main prototypes, including isolated small bowel, liver-small bowel, and multivisceral transplantations. In this review, we describe these three main prototypes and discuss the most important technical modifications of each type, as well as donor and recipient procedures, and highlight the more recent operative technical topics of discussion in the literature.Clinical Transplantation 07/2013; 27 Suppl 25:56-65.
