    背景:本研究的目的是比较小儿LT与左肝移植的结局,从活体捐献者(LD)或分裂的已故捐献者(sDD)获得。
    方法:2002年至2022年的回顾性单中心研究。包括来自LD或sDD的所有具有左肝移植物(不包括肝中静脉)的小儿LT。不包括减少的移植物。
    结果:共进行了112例小儿LT:58例使用LD移植物,54例使用sDD移植物(17例非原位分裂,37例原位移植)。捐赠者特征相似,除了捐赠者年龄(LD与LD的33岁在sDD的30年,p=0.03)。适应症相似,每组有55%的胆道闭锁。sDD组的再移植频率更高(2%vs.15%,p=0.01)。收件人年龄,体重,移植时PELD评分在组间无显著差异。sDD的冷缺血时间更长(LD中158分钟与在sDD中390分钟;p<0.0001)。sDD移植物移植后ALT峰值较高(1470vs.1063,p=0.018),sDD移植的住院时间更长(27vs.21天,p=0.005)。然而,在主要发病率(Dindo-Clavien等级≥3)方面,组间没有差异,血管和胆道并发症,90天死亡率。患者在10年时的生存率为LD的93.1%和sDD的92.8%(p=0.807)。10年时,LD的移植物存活率为89.7%,sDD的移植物存活率为83.1%(p=0.813)。
    结论:技术上相似的LD和sDD移植物获得了非常相似的术后和长期结局,患者和移植物存活良好。
    BACKGROUND: The aim of the present study was to compare the outcomes of pediatric LT with left liver grafts, obtained either from a living donor (LD) or a split deceased donor (sDD).
    METHODS: Retrospective single-center study from 2002 to 2022. All pediatric LT with left liver grafts (not including middle hepatic vein) from LD or sDD were included. Reduced grafts were not included.
    RESULTS: A total of 112 pediatric LT were performed: 58 with LD grafts and 54 with sDD grafts (17 split ex situ and 37 in situ). Donor characteristics were similar, apart from donor age (33 years in LD vs. 30 years in sDD, p = 0.03). Indications were similar with 55% biliary atresia in each group. Retransplantation was more frequently performed in the sDD group (2% vs. 15%, p = 0.01). Recipient age, weight, and PELD score at transplant were not significantly different between groups. Cold ischemia time was longer for sDD (158 min in LD vs. 390 min in sDD; p < 0.0001). Posttransplant peak ALT was higher with sDD grafts (1470 vs. 1063, p = 0.018), and hospital stay was longer with sDD grafts (27 vs. 21 days, p = 0.005). However, there was no difference between groups in terms of major morbidity (Dindo-Clavien grade ≥3), vascular and biliary complications, and 90-day mortality. Patient survival at 10 years was 93.1% for LD and 92.8% for sDD (p = 0.807). Graft survival at 10 years was 89.7% for LD and 83.1% for sDD (p = 0.813).
    CONCLUSIONS: Technically similar LD and sDD grafts achieve very similar postoperative and long-term outcomes with excellent patient and graft survival.

    背景/目的:子宫移植(UTx)已发展成为绝对子宫不育女性的临床现实。UTx的国际经验主要利用了活体捐赠者移植物,尽量减少对捐赠者的伤害的战略仍然至关重要。机器人活体供者子宫切除术代表了一种促进供者快速恢复的微创方法。改善骨盆可视化和手术通道,并维护UTx接收者结果。这项研究的目的是描述捐赠者,收件人,移植,采用机器人活体子宫切除术计划后的妊娠结局。方法:达拉斯UtErus移植研究(DUETS)纳入了机器人活体供体子宫切除术的手术方案,包括经阴道摘除术,从2019年4月。前瞻性收集的数据进行了分析,和一系列案例,描述供体术中和术后结果以及受体术中结果,移植物活力,确定怀孕,和活产。将早期病例与后期病例进行比较,以更好地描述与该技术相关的学习曲线。结果:通过子宫肌层血流和月经开始证明,植入后进行了16例机器人活体子宫切除术,移植物活力为100%。早期经验(8例)显示2例输尿管损伤。后来的经验(8例)表明手术时间减少(11h10minvs.6小时38分钟),无输尿管损伤,主要手术发病率从25%降低到12.5%(Clavien-Dindo等级≥3)。在报告时,已经发生了九次成功的活产,有6次怀孕.结论:机器人活体供者子宫切除术是一种安全的方法,可以在不损害UTx受体的情况下最大程度地减少供者的伤害。移植,和妊娠相关结局。通过采用新技术证明了学习曲线-特别需要注意防止输尿管损伤,鉴于国际上报告的机器人活体子宫切除术的病例数量很少,因此需要持续的警惕和报告。
    Background/Objectives: Uterus transplantation (UTx) has evolved into a clinical reality for women with absolute uterine infertility. The international experience with UTx has predominantly utilized living donor grafts-and strategies to minimize harm to donors remain paramount. Robotic living donor hysterectomy represents a minimally invasive approach to facilitate rapid donor recovery, improve pelvic visualization and operative access, and maintain UTx recipient outcomes. The aim of this study is to describe donor, recipient, graft, and pregnancy outcomes after adoption of a robotic living donor hysterectomy program. Methods: The Dallas UtErus Transplant Study (DUETS) incorporated a robotic living donor hysterectomy operative protocol, including transvaginal extraction, from April 2019. Prospectively collected data were analyzed, and a case series presented, to describe donor intra- and post-operative outcomes and recipient intra-operative outcomes, graft viability, established pregnancies, and live births. Early cases were compared to later cases to better describe the learning curve associated with the technique. Results: Sixteen robotic living donor hysterectomies were performed with 100% graft viability after implantation demonstrated by myometrial flow and onset of menses. Early experience (eight cases) demonstrated two cases of ureteric injury. Later experience (eight cases) demonstrated a reduction in operative time (11 h 10 min vs. 6 h 38 min), with no ureteric injuries and a reduction in major operative morbidity from 25% to 12.5% (Clavien-Dindo grade ≥3). At the time of reporting, nine successful live births have occurred, with six ongoing pregnancies. Conclusions: Robotic living donor hysterectomy represents a safe approach to minimize donor harm without compromising UTx recipient, graft, and pregnancy-related outcomes. A learning curve is demonstrated with the adoption of the novel technique-with particularly care required to prevent ureteric injuries, and ongoing vigilance and reporting necessary given the small case numbers of robotic living donor hysterectomy reported internationally.

    肾移植受者希望在具有足够肾功能的手术中存活下来,以实现可靠的透析自由。
    移植结果(存活率和估计的肾功能)在来自美国国家数据库的活体和死亡供体移植后进行评估。结果按年龄(供体和受体)和供体类型分层。
    总的受者结果是更好的活体移植与死者捐赠的肾脏。然而,当按一年肾功能分层时(在KDIGOCKD阶段分层内),幸存的受者具有临床上相似的透析自由度,无论供体类型或年龄。年龄分层的活体和死亡肾脏的受体的主要结果差异是:1)一年移植失败的频率增加;2)随着供体年龄的增长,严重受限的肾功能(CKD4/5)的可能性增加。超过30%的>65岁的死亡肾脏的接受者患有一年的移植物衰竭或肾功能严重受限,相比之下,年龄>65岁的活肾脏的接受者不到15%。
    改进技术以减少紧急和选择性手术后的不良事件,再加上使用先进的预测分析(使用年龄分层的活体肾移植结果作为相关参考点)对年龄增加的死亡供体肾脏的移植结果可预测性的改善,应该有助于类似的肾移植结果,无论供体类型。
    UNASSIGNED: Kidney transplant recipients expect to survive the procedure with sufficient renal function for reliable dialysis freedom.
    UNASSIGNED: Transplant outcomes (survival and estimated renal function) were assessed after live and deceased donor transplantation from the US national database. Outcomes were stratified by age (donor and recipient) and donor type.
    UNASSIGNED: Aggregate recipient outcomes were better transplanting living vs deceased donated kidneys. However, when stratified by the one-year renal function (within KDIGO CKD stage stratifications), surviving recipients had clinically similar dialysis-freedom, irrespective of donor type or age. The major outcome differences for recipients of age-stratified live and deceased kidneys was 1) the increasing frequency of one-year graft failures and 2) the increasing likelihood of severely limited renal function (CKD 4/5) with advancing donor age. Over 30% of recipients of deceased kidneys >65 years had either one-year graft failure or severely limited renal function contrasted to less than 15% of recipients of live kidneys aged >65 years.
    UNASSIGNED: Evolving techniques to reduce adverse events after urgent vs elective procedures, plus improved transplant outcome predictability with increased-age deceased donor kidneys using advanced predictive analytics (using age-stratified live kidney transplantation outcomes as a relevant reference point) should facilitate similar kidney transplant outcomes, irrespective of donor type.

    While extensive scholarship has been dedicated to the emotional experiences of transplant patients, little is known about the emotional experiences of transplant co-ordinators. Semi-structured face-to-face interviews conducted with ten transplant co-ordinators who have worked for more than 20 years in this job. The transplant co-ordinators spoke of negative feelings and moral distress with regard to futile care of deceased donor family members as well as of living donors. Transplant co-ordinators experience intense negative feelings, emotional pain, and moral distress on a daily basis. Transplant co-ordinators play a pivotal role in the process of obtaining consent for live or dead donation of organ; however, their well-being and job satisfaction are impaired by contradictions between their moral values and the tasks they are instructed to perform. The study exposes the silent emotional suffering of transplant co-ordinators; main findings show that the transplant co-ordinators are torn between contradictory expectations and a gap between values and praxis. It is recommended to offer them training and support for the sake of their retention.

    Due to the severe organ shortage and the increasing gap between the supply and demand for donor grafts, live donor liver transplantation (LDLT) has become an accepted and alternative technique for the expansion of the donor pool. However, donor safety and good recipient outcomes must be balanced regarding risk stratification and decision-making within this patient population. Small-for-size syndrome (SFSS) is one of the complications encountered after LDLT, thus increasing the burden of optimizing donor graft selection and effective treatments during its occurrence. A graft-to-recipient weight ratio (GRWR) <0.8 predisposes the graft to SFSS. However, other factors may induce this complication even without a graft-to-patient size mismatch. Several strategies to prevent this complication include portal vein flow and liver outflow modulation, as well as pharmacological treatment. Also, as an entity with a multifactorial etiology, outcomes vary between right-lobe, left-lobe, and posterior-lobe donation among series encountered in the literature. In this review, we analyze the pathophysiology and classification of this complication, the state-of-the-art on management of SFSS, and the outcomes regarding the best treatment strategy on this patient population.

    To establish the outcome of live kidney donors 5 years after donation, we investigated the risk for progressive renal function decline and quality of life (QoL). Data on estimated glomerular filtration rate (eGFR), creatinine, hypertension, QoL and survival were assessed in a prospective cohort of 190 donors, who donated between 2008 and 2010. Data were available for >90%. The mean age predonation was 52.8 ± 11.5 years, 30 donors having pre-existent hypertension. The mean follow-up was 5.1 ± 0.9 years. Eight donors had died due to non-donation-related causes. After 5 years, the mean eGFR was 60.2 (95% CI 58.7-62.7) ml/min/1.73 m2 , with a median serum creatinine of 105.1 (95% CI 102.5-107.8) μmol/l. eGFR decreased to 33.6% and was longitudinally lower among men than women and declining with age (P < 0.001), without any association on QoL. Donors with pre-existent and new-onset hypertension demonstrated no progressive decline of renal function overtime compared to nonhypertensives. No donors were found with proteinuria, microalbuminuria or at risk for end-stage renal disease. After an initial decline postdonation, renal function remained unchanged overtime. Men and ageing seem to affect renal function overtime, while decreased renal function did not affect QoL. These data support further stimulation of living kidney donation programmes as seen from the perspective of donor safety.

  • 文章类型: Case Reports
    The association between LT and gastrectomy is not common. Only two studies reported the gastrectomy/LT association in children. Here, we report three children who underwent LT who required a concomitant or sequential gastrectomy for different reasons. Patient 1, a 16-yr-old boy, during the LT, underwent a partial gastrectomy due to extensive injury to the duodenum. He had a previous and unusual portoenterostomy performed in the duodenum. Bowel reconstruction was performed using an intestinal loop that was first used for the bilio-enteric anastomosis and then connected to the gastric stump. Patient 2, a 22-month-old female child, underwent a partial gastrectomy with a Roux-en-Y reconstruction during a retransplantation. She had a large perforated gastric ulcer blocked by the allograft liver. Patient 3, a 26-month-old male child, five yr after living donor LT, was submitted to a partial gastrectomy because of gastric outlet obstruction. The histopathology was compatible with eosinophilic gastritis. The association between LT and gastrectomy in the pediatric population is extremely rare. Appropriate knowledge of the previous transplantation technique is very important. Further studies are required to assess the outcomes of the different types of gastric reconstruction in pediatric recipients.

    Kidneys for transplantation are scarce, and many countries give priority to children in allocating them. This paper explains and criticizes the paediatric priority. We set out the relevant ethical principles of allocation, such as utility and severity, and the relevant facts to do with such matters as sensitization and child development. We argue that the facts and principles do not support and sometimes conflict with the priority given to children. We next consider various views on how age or the status of children should affect allocation. Again, these views do not support priority to children in its current form. Since distinctions based on age ought to be positively justified, the failure of all these attempts at justification implies that the priority to children is ethically mistaken. Finally, the paper points to evidence that the paediatric priority reduces the overall supply of kidneys, at least in the United States. Paediatric priority is a real-world policy that seems discriminatory, in some places probably reduces the supply of organs, has no robust official defence, and is unsupported by mainstream ethical principles. Consequently, it should be ended.
