Lung transplantation is still limited by the shortage of suitable donor organs. This results in long waiting times for listed patients with a substantial risk (10-15%) of dying before transplantation. All efforts to increase donor awareness through legislation, public campaigns, and training of transplant coordinators and medical ICU staff should be encouraged. Only a minority of cadaveric donors meets the preset ideal lung donor criteria, leaving many transplantable lungs untouched. Donor lung utilization can be further improved by careful selection of extended criteria donors, by active participation of transplant teams in donor management, and by verifying as often as possible the quality of lungs in the donor hospital by a member of the transplant team. This article aims to update the current evidence from the literature to identify and select potential lung donors and to manage cadaveric donors to maximally increase the organ yield for lung transplantation.

The difference in expression of CA IX and VEGF between intestinal- and diffuse-type adenocarcinomas may possibly explain the different clinical behavior of these tumors. CA IX expression, rather than VEGF positivity in tumors, enables the identification of a subpopulation, characterized by a more aggressive behavior and a poorer prognosis.

Objective: Lung transplantation (LTx) has enjoyed increasing success with better survival in recent years. Nevertheless, airway anastomotic complications (AC) are still a potential cause of early morbidity and mortality. In this retrospective cohort study we looked at possible predictors of AC within the first year after LTx. Methods: Between July 1991 and December 2004, 232 consecutive single (n = 102) and bilateral (n = 130) LTx were performed (142 males and 90 females; mean age: 48 years [range 15-66 years]). Indications for LTx were emphysema (n = 113), pulmonary fibrosis (n = 45), cystic fibrosis (n = 35), pulmonary hypertension (n = 10), sarcoidosis (n = 7) and miscellaneous (n = 22). Donor variables (age, gender, PaO 2 / FiO 2 , mechanical ventilation, ischemic time and preservation solution) and recipient variables (age, diagnosis, length, gender, pre-operative steroids, smoking, cytomegalovirus matching, LTx type, anastomotic type, wrapping and bypass) were evaluated in an univariate and multivariate model. Results: Fifty-seven complications occurred in 362 airway anastomoses (15.7%) of which 55 (15.2%) within the first year after transplantation. Six patients died as a result of AC (mortality 2.6%) during the first year after LTx. In a univariate analysis (321 airway anastomoses at risk), anastomotic type (

DW imaging is a promising tool for differentiating MPD from benign lesions, with high accuracy, and supplementation with DCE MR imaging seems to further improve sensitivity.

SummaryDespite a worldwide need to expand the lung donor pool, approximately 75% of lung offers are not accepted for transplantation. We investigated the impact of liberalizing lung donor acceptance criteria during the last decade on the number of effective transplants and early and late outcomes in our center. All 514 consecutive lung transplants (LTx) performed between Jan 2000 and Oct 2011 were included. Donors were classified as matching standard criteria (SCD; n = 159) or extended criteria (ECD; n = 272) in case they fulfilled at least one of the following criteria: age >55 years, PaO 2 /FiO 2 at PEEP 5 cmH 2 O < 300 mmHg at time of offer, presence of abnormalities on chest X-ray, smoking history, presence of aspiration, presence of chest trauma, or donation after circulatory death. Outcome parameters were primary graft dysfunction (PGD) grade at 0, 12, 24, and 48 h after LTx, time to extubation, stay in intensive care unit (ICU), early and late infection, acute rejection and bronchiolitis obliterans syndrome (BOS), and survival. Two hundred and seventy-two recipients (63.1%) received ECD lungs. PGD grade at T0 was similar between groups, while at T12 (<0.01), T24 (<0.01), and T48 (<0.05), PGD3 was observed more often in ECDs. ICU stay (P < 0.05) was longer in ECDs compared with SCDs. Time to extubation, respiratory infections, acute rejection, lymphocytic bronchiolitis, BOS, and survival were not different between groups. Accepting ECDs contributed in increasing the number of lung transplants performed in our center. Although this lung donor strategy has an impact on early postoperative outcome, liberalizing criteria did not influence long-term outcome after LTx.

Summary Relaxing the standard lung donor criteria may significantly increase the reported 15% organ yield but post‐transplant recipient outcome should be carefully monitored. Charts from all consecutive deceased organ donors within our hospital network were reviewed over a 2‐year period. Reasons for lung refusals and number of lungs transplanted were analysed. Hospital outcome including early recipient survival was compared between standard‐ and extended criteria donors. Out of 283 referrals, 164 (58%) qualified as donor of any organ. The majority (65.9%) of these effective donors were declined for lung donation because of chest X‐ray abnormalities (20%), age >70 years (13%), poor oxygenation (10%), or aspiration (9%). Out of 56 (34.1%) accepted lung donors, 50 transplants were performed at our center, 23 from standard criteria donors versus 27 from extended criteria donors. There were no significant differences in hospital outcome and in early survival between lung recipients from both donor groups. Lung acceptance rate (34.1%) in our donor network is 10–20% higher than reported figures. The number of lung transplants in our center doubled by accepting extended criteria donors. This policy did not negatively influence our results after lung transplantation.

The laparoscopic Nissen fundoplication can safely be performed with a low conversion rate and no surgical mortality in neurologically normal and neurologically impaired children. Neurologically impaired children are more susceptible to per- and postoperative complications. A good quality of life and a high index of satisfaction could be achieved in most patients.

Visual assessment of pleural pointillism on high-b-value DW images is useful to differentiate MPD from benign alterations, performing substantially better than mediastinal pleural thickness and shrinking lung, and might obviate unnecessary invasive procedures for MPM.
