BACKGROUND: Results of donation after circulatory death (DCD) liver transplantation are impaired by graft loss, resulting mainly from non-anastomotic biliary stricture. Donor age is a risk factor in deceased donor liver transplantation, and particularly in DCD liver transplantation. At the authors' institute, age is not an absolute exclusion criterion for discarding DCD liver grafts, DCD donors receive comfort therapy before withdrawal, and cold ischaemia is minimized. METHODS: All consecutive DCD liver transplantations performed from 2003 to 2012 were studied retrospectively. Three age groups were compared in terms of donor and recipient demographics, procurement and transplantation conditions, peak laboratory values during the first post-transplant 72 h, and results at 1 and 3 years. RESULTS: A total of 70 DCD liver transplants were performed, including 32 liver grafts from donors aged 55 years or less, 20 aged 56-69 years, and 18 aged 70 years or more. The overall graft survival rate at 1 month, 1 and 3 years was 99, 91 and 72 per cent respectively, with no graft lost secondary to non-anastomotic stricture. No difference other than age was noted between the three groups for donor or recipient characteristics, or procurement conditions. No primary non-function occurred, but one patient needed retransplantation for artery thrombosis. Biliary complications were similar in the three groups. Graft and patient survival rates were no different at 1 and 3 years between the three groups (P = 0.605). CONCLUSION: Results for DCD liver transplantation from younger and older donors were similar. Donor age above 50 years should not be a contraindication to DCD liver transplantation if other donor risk factors (such as warm and cold ischaemia time) are minimized. [less ▲]

Aim: Results of donation after circulatory death (DCD) liver transplantation (LT) are impaired by ischemic bile duct lesions caused by procurement warm ischemia. Donor age is a risk factor in deceased donor LT, and particularly in DCD-LT. At the authors institute, age is not an absolute exclusion criterion to discard DCD liver grafts, controlled DCD donors receive comfort therapy before withdrawal, and cold ischemia is minimized. The aim of the present study was to report on the results of the first 10 years of this experience, and particularly on graft survival and the rate of post-transplant biliary complications, according to DCD donor age. 
 Methods: The authors retrospectively studied a consecutive series of 70 DCD-LT performed from 2003 to 2012, with at least one year of follow-up. This series was divided according to donor’s age, including 32 liver grafts from donors <55years, 20 between 56 and 69 years, and 18 from older donors >69 years. The three groups were compared in terms of donor and recipient demographics, procurement and transplantation conditions, peak laboratory values during the first post-transplant 72 hours, and results at one and four years. Median follow-up was 43 months. 
 Results: Overall graft survival was 98.5%, 91.4% and 69.5% at 1 month, 1 year and 4 years, respectively, without graft loss secondary to ischemic bile duct lesions. Cancer was the primary cause of graft loss and patient death. No difference other than age was noted between the three groups in donor and recipient characteristics, and in procurement conditions. There was no primary non-function but one patient needed re-transplantation for artery thrombosis. Biliary complications occurred similarly in the three groups. Graft and patient survival rates were not different at one and four years between the three groups. During the study period, there was an increasing liver procurement and transplantation activity, and in 2012, 30% of performed LT were DCD-LT, allowing a mean LT waiting time of 66 days. 
 Conclusions: This study shows comparable results between controlled DCD-LT from younger and older donors. Donor age >50 years should not be a contraindication to DCD-LT if other donor risk factors (such as warm and cold ischemia time) are minimized. DCD-LT with short cold ischemia may provide a significant source of liver grafts, decreasing waiting time. [less ▲]

AIM : FDG uptake has been shown to predict the outcome in large series of patients with hepatocarcinoma (HCC) in Asia, but few data are available regarding European populations. Our aim was to evaluate the prognostic value of pretreatment FDG PET-CT in patients treated by liver transplantation. Methods: We retrospectively analyzed the data of 27 patients (24 M and 3 W, mean age 58 ± 9 years). The mean follow-up was 26 ± 18 months (min 1 month, max 66 months). All patients had an FDG PET-CT before the transplantation. The FDG PET/CT was performed according to a standard clinical protocol: 4 MBqFDG/kg body weight, uptake 60 min., low-dose non-enhanced CT. We measured the SUVmax and SUVmean of the tumor and the normal liver. The tumor/liver activity ratios (RSUVmax and RSUVmean) were tested as prognostic factors and compared to the following conventional prognostic factors: MILAN, CLIP, OKUDA, TNM stage, alphafoetoprotein level, portal thrombosis, size of the largest nodule, tumor differentiation, microvascular invasion, underlying cirrhosis and liver function. Results : The DFS was 87.2% at 1y and 72.1% at 3y. The OS was 85.2% at 1y and 80.7% at 3y. According to an univariate Cox model, RSUVmax, RSUVmean and healthy liver were predictors of DFS and RSUVmax, RSUVmean, size of the largest nodule, CLIP, liver involvement>50%, and healthy liver predicted the OS. According to a multivariate Cox model, only RSUVmax predicted DFS and RSUVmax and liver involvement>50% predicted OS. An ROC analysis of the ratios showed that the 1.15 cut-off for RSUVmax was best for predicting both the DFS (Cox regression:HR 14.4, p=0.02) and OS (HR 5.6, p=0.049). The Kaplan-Meier curves and Logrank tests confirmed those results. Even though the MILAN criteria alone were not predictive, it is worth noting that none of the patients outside the MILAN criteria and with RSUVmax<1.15 relapsed. Conclusions: The RSUVmax is a strong prognostic factor for recurrence and death in patients with HCC treated by liver transplantation with a cut-off value of 1,15. further prospective studies should test whether the metabolic index should be systematically included in the preoperative assessment.

Background. Wider utilization of liver grafts from donors 70 years old could substan- tially expand the organ pool, but their use remains limited by fear of poorer outcomes. We examined the results at our center of liver transplantation (OLT) using livers from donors 70 years old. Methods. From February 2003 to August 2010, we performed 450 OLT including 58 (13%) using donors 70 whose outcomes were compared with those using donors 70 years old. Results. Cerebrovascular causes of death predominated among donors 70 (85% vs 47% in donors 70; P .001). In contrast, traumatic causes of death predominated among donors 70 (36% vs 14% in donors 70; P .002). Unlike grafts from donors 70 years old, grafts from older individuals had no additional risk factors (steatosis, high sodium, or hemodynamic instability). Both groups were comparable for cold and warm ischemia times. No difference was noted in posttransplant peak transaminases, incidence of primary nonfunction, hepatic artery thrombosis, biliary strictures, or retransplantation rates between groups. The 1- and 5-year patient survivals were 88% and 82% in recipients of livers 70 versus 90% and 84% in those from 70 years old ( P .705). Recipients of older grafts, who were 6 years older than recipients of younger grafts ( P .001), tended to have a lower laboratory Model for End-Stage Liver Disease score ( P .074). Conclusions. Short and mid-term survival following OLT using donors 70 yo can be excellent provided that there is adequate donor and recipient selection. Septuagenarians and octogenarians with cerebrovascular ischemic and bleeding accidents represent a large pool of potential donors whose wider use could substantially reduce mortality on the OLT waiting list.

We present the case of a 30-years-old female suffering from a type five maturity onset diabetes of the young deficiency, resulting in type 1 diabetes and terminal renal inssufficiency. She also had chronic and refractory pruritis due to primary sclerosing cholangitis _like fibrosis. She underwent combined en bloc liver and pancreas transplantation and kidney transplantation.The postoperative course was complicated by a gastric outlet obstruction due to compression of the native gastroduodenal junction by the donor aortic tube . This was treated by construction of a roux-en-y gastrojejunostomy at posttransplant day 24. To our knowledge, compression of the gastroduodenal junction by a donor aortic tube after combined liver and pancreas (or multivisceral) transplantation has not been reported previously. [less ▲]

Introduction Orthotopic liver transplantation (OLT) (LTx) using donation after circulatory death (DCD) donors is increasingly performed, but still considered to risk of poorer outcomes compared with standard donations after brain death (DBD)-OLT. Therefore we reviewed our results of DCD-OLT. Patients and Methods Between 2003 and 2010, we performed 30 DCD-OLT (6% of all OLT). We retrospectively reviewed medical records of donors and recipients after DCD versus DBD-OLT to analyze biliary complications, retransplantation rates, and patient/graft survivals. Results Median donor age was similar for DCD and DBD-OLT: 51 versus 53 years (P = .244). Median donor warm ischemia time (stop ventilation to cold perfusion in DCD donors) was 24 minutes. Median cold ischemia time was shorter for DCD (6 hours 54 minutes) compared with DBD-OLT (8 hours 36 minutes; P < .0001). Median laboratory model of end-stage liver disease score was 15 for DCD, and 16 for DBD-OLT (P = .59). Median post-OLT Aspartate Aminotransferase (AST) peak was higher after DCD: 1178 versus DBD-OLT 651 IU/L (P = .005). The incidence of nonanastomotic strictures was different: 33.3% for DCD versus 12.5% for DBD-OLT (P = .001). The overall retransplantation rate was 3% after both DCD and DBD-OLT. After DCD-LTx actuarial 1, 3- and 5-year patient survivals were 93, 85 and 85%, and corresponding graft survivals, 90%, 82%, and 82% respectively, and not different compared with DBD-OLT: 88%, 78%, and 72% (P = .348) and 85%, 74%, and 68% (P = .524) respectively. Conclusion Despite substantial ischemic injury (high peak AST and biliary strictures) short- and long-term survival after DCD-OLT was comparable to DBD-OLT. Rapid donor surgery, careful donor and recipient selection, as well as short warm and cold ischemia times are key factors to optimize outcomes after DCD-OLT. However, strategies to reduce biliary complications remain warranted. [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 ▲]

The thyroid gland is highly vascularized and, in all Thyroid surgery, a special attention must be paid to haemos. tasis and coagulation. Any carelessness in the control of thyroid vessels can indeed entail serious consequences. In this respect, the ultrasonic scalpel represents a significant progress. In this paper, the ultrasonic dissector will first be presented. Then a prospective, randomized trial comparing the results obtained with this apparatus to those obtained with the conventional method of hemostasis in a series of 34 patients submitted to total thyroidectomy for multinodular goiter will be summarized. Without increasing the costs, the ultrasonic dissector allows a saving of operative time as well as a reduction of peroperative bleeding and of postoperative use of antalgics. Finally, the results of 1696 total thyroidectomies performed with the use of the ultrasonic dissector will be briefly outlined. [less ▲]

Medullary thyroid cancer (MTC) arises from parafollicular C cells secreting calcitonin. MTC occurs both as sporadic tumors and as part of specific inherited autosomal dominant syndromes in which point mutations within a discrete set of RET codons were described. Total thyroidectomy and aggressive neck dissection represents the only chance for cure in the affected patients. Therefore, all patients with thyroid nodular disease should undergo measurement of calcitonin plasma levels to allow preclinical diagnosis of the disease and early appropriate surgery ("secondary prevention"). In case of proband patient for inherited disease, all the family members should be genetically screened to detect the disease gene carriers. Patients with germline mutation would benefit either from earlier surgery at the stage of C-cell hyperplasia or microcarcinoma or prophylactic surgery (total thyroidectomy without neck dissection) (primary prevention) before the onset of any C-cells pathology. The ideal age for performance of such prophylactic surgery is determined by the genotypic features of the disease. [less ▲]

Multihormonal bilateral petrosal sinus sampling (BPSS) has been proposed to improve corticotroph microadenomas prediction of lateralisation. Few series have simultaneously compared data of pituitary MRI, surgical findings and multihormonal BPSS. Seven patients (6F/1M) with Cushing's disease, mean age at diagnosis of 35 years (range 24-55) were prospectively studied to compare radiological and multihormonal BPSS data with surgical and pathological findings. In untreated patients, simultaneous measures of ACTH, TSH and prolactine (PRL) were done at time 0, 7, 15, 22 minutes after CRH (500 mg) and TRH (200 mg) stimulation. An intersinus gradient of 1.4 was considered as a lateralisation. All microadenomas were identified during surgery, diameters ranged from 2 to 7 mm. All patients were in long-term surgical remission. Pathological studies confirmed a tumoral tissue with ACTH immunostaining in 6/7 cases and PRL in 3/7 cases. Pituitary MRI correctly identified tumors in 4 cases, the remaining tumors were not seen. Basal and stimulated intersinus gradients of ACTH, TSH and PRL were homolateral in 6/7 cases and were coincident with surgical findings in 4/7 cases. The other three cases were contralateral to MRI and surgical data. In conclusion, simultaneous gradient of ACTH, PRL and TSH did not improve lateralisation prediction in this series. Hormonal hypersecretion was homolateral in six cases whereas pathological studies demonstrated a mixed secretion in only three cases. A preferential pituitary draining could explain these discordances. Data from our series and from others (done with CRH stimulation and ACTH-PRL measures) strongly suggest a paracrine interaction between tumoral and normal pituitary tissue. [less ▲]
