This document was developed through the collaborative efforts of Society Critical Care Medicine, American College Chest Physicians, and Association Organ Procurement Organizations. Under auspices these societies, a multidisciplinary, multi-institutional task force convened, incorporating expertise in critical care medicine, organ donor management, transplantation. Members were divided into 13 subcommittees, each focused on one following general or organ-specific areas: death determination...

A large prospective, open-label, randomized trial evaluated conversion from calcineurin inhibitor (CNI)- to sirolimus (SRL)-based immunosuppression for preservation of renal function in liver transplantation patients. Eligible patients received allografts 6-144 months previously and maintenance with CNI (cyclosporine or tacrolimus) since early posttransplantation. In total, 607 were (2:1) abrupt (<24 h) SRL (n = 393) continuation up 6 years 214). Between-group changes baseline-adjusted mean...

Alcoholic liver disease (ALD) is a common indication for transplantation worldwide. This study identifies factors predicting posttransplant recidivism.Clinical and laboratory data were reviewed. Uni- multivariate analyses survival relapse to alcohol illicit drugs performed.Between July 1995 November 2007, 387 patients underwent at our institution. Of these, 147 (38%) found have ALD. Five (3.4%) excluded because of perioperative mortality. Overall was 96.2%, 89.6%, 84.4% 1, 3, 5 years,...

To investigate independent contributions of obesity, diabetes, and smoking to resource utilization in patients following liver resection.Despite being highly resource-intensive, resections are performed with increasing frequency. This study evaluates how potentially modifiable factors affect measures after hepatectomy.The American College Surgeons' National Surgical Quality Improvement Program (ACS NSQIP) public-use database was queried for undergoing resection. Resource variables were...

Background. The piggyback technique (PT), with preservation of the cava, is being used more frequently in adult orthotopic liver transplantation (OLT). advantages PT include hemodynamic stability during anhepatic phase without a large‐volume fluid infusion and obviating need for veno‐venous bypass (VVB). At our center, we changed practice July 1997 from standard (ST) OLT routine use VVB to selective VVB. purpose present study was analyze results two different practices, ST‐routine versus...

The biliary anastomosis has been called 'the Achilles heel' of liver transplantation (RABKIN JM, ORLOFF SL, REED MH. Transplantation 1998: 65 [2]: 193; DAVIDSON BR, RAI R, KURZAWINSKI TR. Br J Surg 1999: 86 [4]: 447). Biliary complications after reportedly occur at an incidence 20-30%, 10-15% as bile leaks. management leaks, especially early is controversial. In the present study, we report our experience with leaks transplantation. this retrospective reviewed 85 transplants over a 3-yr...

Since the first description by Ratner and collegues in 1996, laparoscopic live-donor nephrectomy is gaining wide acceptance an attempt to minimize donor morbidity, length of hospital stay time return work. It unknown whether multiple renal arteries pose additional problems with nephrectomy. In November 1998, our institution initiated program. ensuing 19 months, we performed 25 living transplants, 24 them using The left kidney was procured all cases. Eight candidates (33%) had two or more...

Pancreas transplantation is an established treatment for selected type I insulin-dependent diabetes mellitus (DM). Increasingly, enteric drainage of exocrine secretions has been performed in preference to bladder drainage. We present two cases massive gastrointestinal hemorrhage (GIH) related arterial-graft duodenal fistulas, a rare cause bleeding. Case 1 DM 49-year-old male who underwent simultaneous kidney pancreas (SPK) and end-stage renal disease (ESRD). He developed transplant stump...

Faced with an extreme shortage of organs transplant professionals continue to explore various strategies expand the donor pool. Transplantation kidneys from older and very young donors are two such options. Although (less than 5 years age) have been associated a high rate technical complications suboptimal results, use these en bloc has advocated improve outcomes. We reviewed our experience kidney transplantation at University Kentucky over past 10 years. Between 1991 2000 ten patients...

Extrahepatic arteriovenous malformations (AVMs) of the gastrointestinal (GI) tract are rare and mostly asymptomatic congenital anomalies. The present case describes a 45-year-old woman with an AVM in head pancreas, which caused massive GI bleeding that recurred after embolization, was subsequently treated pylorus-preserving Whipple pancreaticoduodenectomy. authors then review available literature pertaining to AVMs tract, diagnostic modalities have been used identify them treatment...
