The management of failure of colonic graft or corrosive stricture with impaired colonic circulation continues to be a challenge to surgeons. We present four cases of complicated corrosive esophageal stricture, which were successfully treated using jejunal free graft. As the initial surgical treatment, three patients underwent colonic interposition, and one underwent Whipple's procedure due to panperitonitis. Ore patient underwent transposition of jejunal free patch graft, two underwent interposition of jejunal free graft, and one underwent esophagojejunocolojejunostomy using jejunal free graft. All patients did not show dysphagia after long term follow-up. Complex esophageal reconstruction with jejunal free graft was performed successfully and long term functional outcome was good.

Xenotransplantation of porcine organs has the potential to overcome the severe. shortage of human tissues and organs available for human transplantation. The swine represents an ideal source of such organs because of their plentiful supply and their numerous anatomical and physiological similarities to the human. However, this procedure also carries with a number of safety issues relating to the zoonotic infections. Porcine endogenous retrovinJses(PERVs), \Wich are germ line transmitted and persist without symptoms in the pigs, are most concerning zoonotic viroses. In order to analyze the prevalence of PERV in domestic pigs, four kinds of pigs'(Landrace, Berkshire, Yorkshire, and Duroc) genomic DNA were isolated from their hair follicles. PCR analysis was carried out for detection of PERVs using subgroup A/B/C and E pol sequence primers. All pigs (20 heads) tested had high copy number of PERVs within genomes. Subgroup A/B/C and E pol gene sequences from 20 isolates were determined by direct sequencing. Sequence analysis showed pol sequences are highly conserved among intra- and inter-subspecies(99.l and 98.8%, respectively). As a first report of PERV prevalence in Korea pigs, our data would be the basic concepts of PERV transmission study in xenotransplantation.

Purpose: This study was designed to create the job description of Korean transplantation nurse practitioner and examine performance frequencies, criticality, and difficulties of task elements. Method: The sample consisted of 63 nurses and coordinators who performed duties related to transplantation at medical center in Korea. A survey method was used, and the questionnaire included frequencies, criticality, and difficulties of task elements in job description by the DACUM method. Using SPSS WIN 10.0, descriptive statistics such as frequency distribution, means, and standard deviations were conducted to examine the subject's general characteristics, the frequencies, criticality, and difficulties of task performance. Result: The job description of transplantation nurse practitioners revealed 5 duties, 22 tasks, and 85 task elements. On the all five duties, the averages of the performance frequency, criticality, and difficulty were 2.41, 3.38, and 2.78, meaning that the respondents rarely perform the 5 duties, but consider them critical and easy to perform. Conclusion: The job description of the transplantation nurse practitioner included duty, task, and task element and definition of job completed. Thus we recommended a data based trial to confirm and validate the information gathered.

Purpose: The purpose of this phenomenological study was to understand the experiences in the transplantation coordinators' practice. Method: Data was collected through a tape-recorded in-depth interview from nine participants who were transplantation coordinators of their hospitals. It was analyzed using the phenomenological method proposed by Colaizzi(1978). Results: From significant statements, six categories of themes were integrated into the essential structure of the experiences of transplantation coordinators. Six categories of themes were 'continue to be professional during dash this way and rush that', 'burden due to persistent heavy work', 'the uniqueness in family care of the brain-dead patients', 'support of family and a professional group', 'worthiness and achievement of the patients' recovery', and 'establishment of self-confidence as a coordinator'. Conclusion: Although the transplantation coordinators played various roles, they had a conflict in role identity due to poor working environments. The results of this study suggested that development of an educational program, an increase in understanding for the coordinators' role, and institutional support for better working conditions are needed to get professional acknowledgement for transplantation coordinators.

Purpose: Along the process of organ transplantation, coordinators perform complex professional roles, playing as a key person among recipients, donors, family members and medical staffs. The purpose was to analyze the tasks of organ transplantation coordinators using DACUM method and to establish the basis for standardizing them in accordance with relevant laws and systems. Methods: Participants were consisted of 78 transplantation coordinators working at the medical centers in Korea. The questionnaire was administered to analyze the criticality, difficulty and frequency of task elements. Results: The job of organ transplantation was classified into five duties, 13 tasks, and 84 task elements. The five duties were recipient management, donor management, organ donation activation management, organ transplantation administration, and professional capability development. On the four-point scale: donor management was the duty with the highest criticality (3.68), organ donation activation management was the duty of highest difficulty (2.96), and recipient management was the duty of the highest frequency (3.32). Conclusion: This study will be useful for developing an educational program and as a reference of nurse practitioner qualifying examination. It is necessary to develop a comprehensive educational program for transplantation coordinators in order to support them to take their complex roles successfully.

Purpose: The aim of this study was to compare the levels of anxiety, depression, and quality of life (QOL) among kidney or liver transplant candidates and recipients. Methods: A cross-sectional descriptive design was utilized. The 160 subjects were recruited and assigned to three different conditions: awaiting transplant group; post-transplantation (TPL) group within less than one year of surgery; and post-TPL group with one year and no more than two years post surgery. The levels of anxiety and depression were measured by the Hospital Anxiety and Depression Scale. The level of quality of life was measured by the Medical Outcomes Study Short Form-36 version 2. Results: The anxiety score was significantly higher in the waiting group compared with the 1~2 years post TPL group. The depression score was significantly higher in the waiting group compared with the post TPL groups. The QOL was significantly lower in the waiting group compared with the post TPL groups. Conclusion: Our results show a high prevalence of anxiety and depression and a marked reduction in the QOL in transplant candidates compared to the recipients. This study indicates that the group waiting for transplants may have unmet needs during that time period. Health professionals should be encouraged to attend to the psychological distress of the transplant candidates in order to improve their quality of life.

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.
