Use of Nonvascularized Abdominal Rectus Fascia After Liver, Small Bowel, and Multiorgan Transplantation: Long-Term Follow-up of a Single-Center Series.

BACKGROUND: The abdominal wall may be severely compromised in the vast majority of intestinal and multiorgan transplant candidates, and sometimes as a consequence of complex liver transplantation. Multiple options have been described to overcome this problem, varying from component separation to the extreme need of performing an abdominal wall transplantation. The aim of the present paper is to report the largest and longest-term results of patients that received an abdominal rectus fascia (ARF) after liver, intestinal, or multiorgan transplantation at a single transplant center. METHODS: This is a retrospective report of a prospectively collected dataset of all the patients that received ARF during liver, isolated intestine, combined, or multiorgan transplantation at Fundación Favaloro from May 2006 to June 2016. RESULTS: A total of 19 out of 528 patients (3.5%) that underwent abdominal organ transplant received an ARF graft: 17 patients after receiving an intestine-containing graft, and 2 after liver retransplantations. Three patients required changing the ARF, 2 with a synthetic mesh and 1 with another ARF. Five patients required late reoperations: A relaparotomy was performed by transecting the ARF without encountering adhesions on the inner ARF surface. None of the 2 patients who received liver retransplantations and ARF developed acute or chronic ventral defects. CONCLUSIONS: The use of ARF is a simple and reliable surgical option to close abdominal wall defects during transplantation, the fascia adequately incorporates to the abdominal wall, allowing it to be transected and resutured in the long term and preserving the integrity of the peritoneal layer.

Short- and long-term outcomes of every graft recovered during a multi-organ procurement procedure including the intestine.

BACKGROUND: The development of intestinal transplant (Tx) programs introduces thymoglobulin donor treatment as well as an almost complete warm dissection of the abdominal organs to allocate them to different recipients. Our aim is to assess the reproducibility and feasibility of the surgical technique of multi-organ procurement with the use of thymoglobulin donor pre-treatment and report the short- and long-term outcomes of every graft harvested as part of multi-organ procurement (MTOp), including the intestine. METHODS: Data were collected of all organs harvested from MTOp, including the intestines allocated to our center from March 2006 to July 2011. Data from 92 recipients and 116 organs procured from 29 MTOp were analyzed. Twelve hearts, 2 lungs, and 1 cardio-pulmonary block were transplanted; primary graft dysfunction developed in 4 of the 12 hearts and in the cardio-pulmonary block. RESULTS: The survival rate was 75% and 100% for hearts and lungs, respectively. Nineteen livers, 9 kidney-pancreas, 19 kidneys, and 29 intestines were transplanted. Delayed graft function (DGF) of the pancreas developed in 3 of 9 kidney-pancreas, and the other 3 exhibited DGF of the kidney; 4 of 19 Tx kidneys had DGF. The survival was 84%, 78%, 95%, and 65.5% for livers, kidney-pancreas, kidneys, and intestines, respectively. CONCLUSIONS: Organs procured during MTOp including the intestine can be safely used, increasing organ availability and transplant applicability without compromising allocation, quality, and long-term results of the non-intestinal-procured organs.

Intrapancreatic common hepatic artery arising from the superior mesenteric artery, a challenging anatomic variation in a multiorgan harvesting.

INTRODUCTION: Understanding abdominal vascular anatomy is crucial for multiorgan recovery. In this case report, we have described a common hepatic artery that arises from the superior mesenteric artery but follows an intrapancreatic course. METHODS: The donor was ideal for multiorgan recovery and the recipient was a 29-year-old woman awaiting a second transplant owing to primary nonfunction of her first engrafted organ. The indication for transplantation was secondary biliary cirrhosis. A type I diabetic recipient on dialysis therapy was awaiting the kidney and pancreas. RESULTS: The urgent condition of our liver recipient combined with the anatomical finding prioritized liver procurement, therefore the pancreas was discarded. CONCLUSIONS: The recognition of all anatomic variations will allow us to improve the use of the scarce resource of deceased donor organs.

Neo-suprahepatic cava: a case report of a modified technique for domino liver transplantation.

Domino liver transplantation, introduced in 1997, originally consisted of a graft from a patient with familial amyloidotic polyneuropathy used as a donor for a compatible recipient, thus increasing the pool of hepatic grafts for liver transplantation. The aim of this report was to present a modification on the technique for outflow reconstruction in domino liver transplantation first proposed by Liu et al and Cescon et al. In this description we proposed a new technique that differs from the one mentioned above by performing a neo-suprahepatic cava, constructed using only an iliac vein graft, facilitating the anastomosis as if it was a regular cadaveric liver transplant.
