Bariatric surgery has proven its efficacy to obtain a marked and sustained weight loss and dramatically improve metabolic control in obese patients with type 2 diabetes. The frequently observed remission of diabetes occurs very early, before any significant weight reduction. Increasing evidence suggests that this favourable effect results from profound changes in gut hormones involved in the regulation of energy intake behaviour and glucose homeostasis rather than simply from mechanical food restriction or malabsorption imposed by the surgical procedure. These hormonal changes result from partial stomach amputation (leading to reduced ghrelin secretion), from bypass of duodenal-jejunal foregut (leading to reduced secretion of still unknown factors that may counteract insulin secretion and/or action) and from an earlier contact of food with hindgut (leading to enhanced secretion of incretin hormones such as glucagon-like peptide-1 [GLP-1] by the ileal L cells, neuropeptide YY and oxyntomodulin). The better knowledge of these pathophysiological mechanisms, especially well studied with Roux-en Y gastric bypass, resulted in recent innovation in the technical procedures leading to a shift from bariatric surgery to metabolic surgery.

INTRODUCTION: End-stage renal disease is a major public health problem in Viet Nam. A cooperative project between the University of Liege, Belgium, and the University of Medicine Pham Ngoc Thach, Ho Chi Minh City, Viet Nam, has permitted the establishment of an autonomous program of renal transplantation from living-related donors at the Peoples' Hospital No 115. The aim of this paper was to report the primary results of the project and to draw conclusions for the future. PATIENTS AND METHODS: From January 2004 to July 2008, we performed 33 living-related renal transplantations. Mean ages of donors and recipients were 31.8 +/- 9.5 and 41.6 +/- 13.5 years, respectively. Laparoscopic nephrectomy was performed in 6 donors. The immunosuppressive regimen consisted of three drugs associated with induction therapy using anti-interleukin-2 receptor monoclonal antibody. RESULTS: The 33 donors are in good health at follow-up. Four developed major intra- or postoperative hemorrhage necessitating transfusion, with a surgical re-exploration in 1 donor. Wound infection occurred in 2 donors. Posttransplant recipient and graft survivals at 1 versus 3 years were 82% and 73% versus 82% and 65%, respectively. Eight recipients presented 13 biopsy-proven acute rejection episodes that were reversible in 7, but 1 patient lost his graft due to an irreversible rejection. Two recipients developed cancer. CONCLUSIONS: These initial results have encouraged us to continue the program of renal transplantation from living-related donors. However, they also pointed out the need to develop other donor sources. [less ▲]

OBJECTIVE: In this study, we have evaluated the organ procurement and transplantation activity from donors after cardiac death (DCD) at our institution over an 8-year period. Our aim was to determine whether this program influenced transplantation programs, or donation after brain death (DBD) activity. METHODS: We prospectively collected our procurement and transplantation statistics in a database for retrospective review. RESULTS: We observed an increasing trend in potential and actual DCD number. The mean conversion rate turning potential into effective donors was 58.1%. DCD accounted for 16.6% of the deceased donor (DD) pool over 8 years. The mean age for effective DCD donors was 53.9 years (range, 3-79). Among the effective donors, 63.3% (n = 31) came from the transplant center and 36.7% (n = 18) were referred from collaborative hospitals. All donors were Maastricht III category. The number of kidney and liver transplants using DCD sources tended to increase. DCD kidney transplants represented 10.8% of the DD kidney pool and DCD liver transplants made up 13.9% of the DD liver pool over 8 years. The DBD program activity increased in the same time period. In 2009, 17 DCD and 33 DBD procurements were performed in a region with a little >1 million inhabitants. CONCLUSION: The establishment of a DCD program in our institution enlarged the donor pool and did not compromise the development of the DBD program. In our experience, DCD are a valuable source for abdominal organ transplantation. [less ▲]

Confronting the organ donor shortage, many transplant centers around the world increasingly use donors after cardiac death (DCD). Over the past 20 years, follow-up studies in kidney recipients comparing DCD and donors after brain death (DBD) have shown comparable long-term graft function and survival. As a consequence, DCD programs should be continued and expanded, for these donors constitute a potential solution to the imbalance between the numbers of end-stage kidney disease patients on waiting lists versus available kidney grafts. DCD kidneys do not necessarily signify suboptimal grafts; they may merit to be allocated the same as DBD grafts. [less ▲]

The Belgian experience with donation after cardiac death (DCD) liver transplantation (LT) was retrospectively reviewed, particularly evaluating patient and graft survivals, and biliary complications. From 2003 to 2007, 58 DCD-LT were performed in Belgium. Mean procurement total warm ischemia time was 25 +/- 2 min (mean +/- SEM). Mean cold ischemia time was 451 +/- 18 min. Mean follow-up was 23 +/- 2.2 months. Post-transplant peak aspartate aminotransminases was 2241 +/- 338 UI/l. Patient survivals at 1 month, 1 and 3 years, were 91.3%, 83.3% and 66.9% respectively. Graft survivals at 1 month, 1 and 3 years, were 84.4%, 72.4% and 48.8% respectively. Two patients (3.4%) developed primary nonfunction. Regarding the biliary complications, seven grafts (12%) were lost because of intrahepatic cholangiopathy, and 12 other patients (20.6%) developed bile duct stenoses requiring endoscopic and/or surgical management. The rate of symptomatic ischemic biliary lesions for grafts surviving more than 3 months was 38% (19/50). Although DCD organ donors may be a source of viable liver grafts, results were inferior to those obtained with donation after brain death LT in this series. Prognostic criteria have to be developed to improve results of DCD-LT. [less ▲]

Euthanasia was legalized in Belgium in 2002 for adults under strict conditions. The patient must be in a medically futile condition and of constant and unbearable physical or mental suffering that cannot be alleviated, resulting from a serious and incurable disorder caused by illness or accident. Between 2005 and 2007, 4 patients (3 in Antwerp and 1 in Liège) expressed their will for organ donation after their request for euthanasia was granted. Patients were aged 43 to 50 years and had a debilitating neurologic disease, either after severe cerebrovascular accident or primary progressive multiple sclerosis. Ethical boards requested complete written scenario with informed consent of donor and relatives, clear separation between euthanasia and organ procurement procedure, and all procedures to be performed by senior staff members and nursing staff on a voluntary basis. The euthanasia procedure was performed by three independent physicians in the operating room. After clinical diagnosis of cardiac death, organ procurement was performed by femoral vessel cannulation or quick laparotomy. In 2 patients, the liver, both kidneys, and pancreatic islets (one case) were procured and transplanted; in the other 2 patients, there was additional lung procurement and transplantation. Transplant centers were informed of the nature of the case and the elements of organ procurement. There was primary function of all organs. The involved physicians and transplant teams had the well-discussed opinion that this strong request for organ donation after euthanasia could not be waived. A clear separation between the euthanasia request, the euthanasia procedure, and the organ procurement procedure is necessary. [less ▲]

Hepatocellular carcinoma is the main primitive tumor of the liver. It occurs in the setting of liver cirrhosis in more than 90% of the cases in developping countries. The prognosis depends on the size, number and extension of the tumor as well as on the severity of the underlying liver disease. The Barcelona Clinic Classification takes into account these different parameters and helps the clinician in the therapeutic decision. Some patients (around 25%) are amenable to therapy with a curative intent (liver transplantation, resection, destruction by radiofrequency). In patients with hepatocellular carcinoma at an intermediate stage, lipiodolized chemoembolization gives a survival advantage in comparison with placebo. No conventional regimen of chemotherapy has a proven survival benefit. In patients with a hepatocellular carcinoma at an advanced stage, sorafenib, an oral multi-targeted kinase inhibitor, is the first coumpound to demonstrate a significant effect on survival free of disease progression in a selected group of patients. Its toxicity profile is particularly favourable. Combination of surgical and medical therapies should be properly evaluated in clinical trials in the near future. [less ▲]

Aim: Donation after cardiac death (DCD) has been proposed to partly overcome the organ donor shortage. In liver transplantation, the additional warm ischemia linked to DCD procurement may promote higher rate of primary non-function and ischemic type biliary lesions. In this study we reviewed the results of DCD liver transplantation at the University of Liège. Patients and Methods: From 2003 to 2007, 13 controlled DCD liver transplantations were consecutively performed. The records of all donors and recipients were retrospectively reviewed, particularly evaluating the outcome and the occurrence of biliary complications. Mean follow-up was 25 months. Results: Mean donor age was 51 years and their mean intensive care stay was 5.4 days. Mean time between ventilation arrest and cardiac arrest was 9.3 min. Mean time between cardiac arrest and arterial flush was 7.7 min. No touch period was 2 to 5 min. Mean graft cold ischemia was 295 min and mean suture warm ischemia was 38 min. Postoperatively there was no primary non-function. Mean peak transaminase was 2,546 UI/ml. Patient and graft survival was 100% at one year. Two patients (15%) developed graft main bile duct stenosis and underwent endoscopic management. No patient developed symptomatic intrahepatic bile duct strictures or needed retransplantation in the follow-up. Conclusions: The experience of the transplantation department of the University of Liege confirms that controlled DCD donors may be a valuable source of transplantable liver grafts, in case of short procurement warm ischemia and short transplant cold ischemia.
