ABO 부적합성 장기이식은 이미 존재하는 항체에 의한 초급성 및 급성 면역 거부반응 때문에 심장이식을 포함한 대부분의 장기이식에서 금기시 되어왔다. 그러나 ABO 부적합성 장기이식이 혈장교환, 항체흡착술, 면역억제, 비장절제술 등에 의해 성공적으로 치료되었다는 여러 보고가 나오고 있다. 우리는 혈장교환과 면역억제에 의한 ABO 부적합성 심장이식의 성공적인 치료를 경험했다. 그러나 이것이 ABO 부적합성 심장이식술을 정당화하는 것은 아니며, 계속되는 급성면역거부 반응이나 만기거부반응에 대한 ABO 부적합성의 관련이 충분히 알려지지 않았기 때문에 장기 추적검사가 요구된다.

Background Face transplantation has naturally evolved from reconstructive procedures. However, few institutions perform face transplantations, because it is time-consuming and it is necessary to justify non-vital organ transplantation. We investigated the process of organ donation from brain-dead patients and the possibility of incorporating face transplantation into the donation process. Methods A retrospective review was performed of 1,074 brain-dead patients from January 2015 to December 2016 in Korea. We analyzed the time intervals from admission to brain death decisions (first, second, and final), the causes of brain death, and the state of the transplanted organs. Results The patient base (n=1,074) was composed of 747 males and 327 females. The average period between admission to the first brain death decision was 8.5 days (${\pm}15.3$). The average time intervals between the first brain death decision and medical confirmation using electroencephalography and between the first brain death decision and the final determination of brain death were 16 hours 58 minutes (${\pm}14hours$ 50 minutes) and 22 hours 57 minutes (${\pm}16hours$ 16 minutes), respectively. The most common cause of brain death was cerebral hemorrhage/stroke (42.3%), followed by hypoxia (30.1%), and head trauma (25.2%). Conclusions When face transplantation is performed, the transplantation team has 22 hours 57 minutes on average to prepare after the first brain death decision. The cause of brain death was head trauma in approximately one-fourth of cases. Although head trauma does not always imply facial trauma, surgeons should be aware that the facial tissue may be compromised in such cases.

Liver transplantation is widely accepted as an effective therapeutic modality for a variety of irreversible acute and chronic liver diseases for which no satisfactory therapy is available. Following the first unsuccessful efforts at human liver transplantation in 1963, development of the procedure evolved at first slowly and steadily for 20 years and then rapidly over the past two decades. The growth of liver transplantation was facilitated by the conclusion of the national institutes of health consensus development conference in 1983 that liver transplantation is not an experimental procedure but an effective therapy that deserves broader application. The number of liver transplantations increased 2.4-fold(from 1.713 to 4.058) from 1988 to 1996. but the number of patients on the UNOS(united network of organ sharing) liver list increased 12.1-fold(from 616 to 7,467); as would be expected, the number of deaths of listed patients increased 4.9-fold(from 195 to 954), The current supply of donor livers is insufficient to meet this need, and organ donation has been stagnant or increased by only a few percent in recent years. These facts underscore the importance of the appropriate selection of candidates for liver transplantation and the development of operative procedures, such as living donor liver transplant, split liver transplant and auxiliary partial liver transplant.

Background Dupuytren's disease decreases quality of life significantly and often requires surgical treatment, nevertheless there is no actual gold standard. The aim of this study was to introduce the use of minimally invasive pull-through technique. Methods From 2016 to 2020, 52 patients suffering from Dupuytren's contracture were treated with the minimally invasive pull-through technique. We evaluated the improvement in range of motion, pain, disability, and quality of life in the long term. Total extension deficit, quick disabilities of the arm, shoulder, and hand (QuickDASH), and EuroQol five dimensions-five levels index were systematically scored before each surgical intervention and reevaluated after 24 months. Results Fourteen patients (26.9%) had already received a previous intervention (percutaneous needle aponeurotomy or collagenase Clostridium histolyticum). The mean preoperative total active extension deficit was 84.0 ± 23.3 degrees (55-130 degrees). Mean follow-up was 36 months. There were no cases of tendon rupture or neurovascular injury. Total active extension deficit at the final follow-up was 3.4 ± 2.3 degrees (0-12 degrees). The mean active range of motion of the MCP and PIP joints were, respectively, 90.5 ± 3.3 degrees (85-96 degrees) and 82.7 ± 2.5 degrees (80-87 degrees). At 24 months after cord excision, a mean 10.7 points improvement in the QuickDASH questionnaire was registered (p < 0.001). Pull-through technique was equally effective both on patients with a primary or a recurrent disease. Eight patients (15.4%) had a recurrence of disease in the metacarpophalangeal joint or proximal interphalangeal joint. Conclusion The pull-through technique is a simple, accessible, and effective technique for the treatment of Dupuytren's contracture. The use of palmar mini-incisions combined with minimal dissection has a low risk of iatrogenic injury to the neurovascular bundles and tendons, and has a low risk of recurrence rate. This study reflects level of evidence IV.

Although organ transplants have become quite common, combined heart-lung transplantation (CHLTx) is unfamiliar at most institutions. While the remarkable rate of development in treatment options, such as drugs and mechanical circulatory support, have reduced the need for CHLTx, it remains the sole treatment option for a subset of patients with end-stage cardiopulmonary failure. For many cardiothoracic surgeons, CHLTx is not technically new or difficult, but it does pose challenges due to its low frequency and relative complexity. Thus, this review aims to describe the CHLTx technique in technical detail using the existing literature.

Lung transplantation is a life-saving procedure in patients with end-stage lung disease. However, it inherently depends on the availability of donor organs. The selection of suitable lungs for transplantation, management of donors to minimize further injury and improve organ function, and safe procurement remain critical for successful transplantation. In this review, we provide an update on the current understanding of donor selection, management, and lung procurement.

Background: Extracorporeal life support (ECLS) can be applied in brain-dead donors for organ perfusion before donation, thereby expanding the donor pool. The aim of this study was to examine the benefits and early clinical outcomes of ECLS for organ preservation. Methods: Between June 2012 and April 2017, 9 patients received ECLS with therapeutic intent or for organ preservation. The following data were collected: demographics, purpose and duration of ECLS, cause of death, dose of vasoactive drugs, and need for temporary dialysis before organ retrieval. The early clinical outcomes of recipients were studied, as well as survival and graft function at 1 month. Results: ECLS was initiated for extracorporeal cardiopulmonary resuscitation in 5 patients. The other patients needed ECLS due to hemodynamic deterioration during the assessment of brain death. We successfully retrieved 18 kidneys, 7 livers, and 1 heart from 9 donors. All organs were transplanted and none were discarded. Only 1 case of delayed kidney graft function was noted, and all 26 recipients were discharged without any significant complications. Conclusion: The benefits of protecting the vital organs of donors is significant, and ECLS for organ preservation can be widely used in the transplantation field.

Purpose: This study was conducted to investigate the factors that influence the psychosocial adjustment of organ transplant recipients. Methods: Participants were 132 organ transplant recipients who received follow-up more than 3 months after the organ transplantation at one general hospital in Seoul. A questionnaire survey was done from November 3 to December 3, 2015. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient, and hierarchical multiple regression. Results: Family support, medical staff support and hope were significantly correlated with psychosocial adjustment. In the hierarchical multiple regression analysis, hope appeared to be the most important factor influencing psychosocial adjustment (${\beta}=.39$, p<.001). Conclusion: The findings show that hope had an influence on the psychosocial adjustment of organ transplant recipients. Thus, to improve psychosocial adjustment it is important for nurses to develop interventions to increase hope in organ transplant recipients.

심장과 신장의 경우 현대의학에서 이식이 중요한 치료방법으로 자리잡고 있으며 그 적응증이 확대되고 있다. 그러나 만성신부전은 심장이식의 금기였으며, 심부전도 신장이식의 금기로 심장과 신장의 동시이식이 이루어지는 경우는 흔치 않았다. 하지만 심부전과 신부전에 대한 치료의 발달로 심장-신장 동시이식의 필요성은 증가하고 있으며 동시에 면역학의 발달과 수술 기술 등의 발달로 그 가능성은 높아지고 있다. 우리나라에서는 지난 1969년과 1992년에 신장이식과 심장이식이 각각 성공하였으나 그동안 동시이식은 없었다. 본 증례는 분만 후 발생한 심근병증으로 심부전이 발생하고 이로 인한 신부전으로 투석을 받던 33세의 여자환자에 대해 본원에서 1년 전 시행한 '심장-신장 동시이식'에 대한 보고이다. 현재 환자는 정상 심장기능에 투석 없이 건강하게 생활하고 있으며 이에 그 결과를 문헌 고찰과 더불어 증례 보고하는 바이다.

Orthotopic liver transplantation is the treatment of choice for inherited metabolic diseases. However, the supply of donor organs is limiting and therefore many patients cannot benefit from this therapy. In contrast, hepatocytes can be isolated from a single donor liver. They can be transplanted into several recipients, and this procedure may help overcome the shortage of donor livers. A great deal of work with animal models indicates that hepatocytes transplanted into the liver or spleen can survive, function, and participate in the normal regenerative process. Recent clinical studies suggest that hepatocyte transplantation may be useful for bridging patients to whole organ transplantation and for providing metabolic support during liver failure and for replacing whole organ transplantation in certain inherited metabolic diseases. Nowadays, hepatocytes from various stem cells have been regarded as an another cell source for treatment of inherited metabolic diseases. Although cell therapy using stem cells for inherited metabolic disease patient has been accepted only as an experimental trial yet, hepatocytes from stem cells can solve a lot of obstacles in the treatment of inherited metabolic diseases.
