Living donor liver transplantation is increasingly performed as an alternative to cadaveric transplantation. Preoperative screening of the donor candidates is very important. The quality, size, and vascular and biliary anatomy of the liver are best assessed with magnetic resonance (MR) imaging or computed tomography (CT). In particular, the volume of the potential graft must be measured to ensure sufficient liver function after surgery. Preoperative liver segmentation has proved useful for measuring the graft volume before living donor liver transplantations in previous studies. In these studies, the liver segments were manually delineated on each image section. The delineated areas were multiplied by the section thickness to obtain volumes and summed to obtain the total volume of the liver segments. This process is tedious and time consuming. To compensate for this problem, automatic segmentation techniques have been proposed with multiplanar CT images. These methods involve the use of sequences of thresholding, morphologic operations (ie, mathematic operations, such as image dilation, erosion, opening, and closing, that are based on shape), and 3D region growing methods. These techniques are complex but require a few computation times. We made a phantom for volume measurement with pig and evaluated actual volume of spleen and liver of phantom. The results represent that our semiautomatic volume measurement algorithm shows a good accuracy and repeatability with actual volume of phantom and possibility for clinical use to assist physician as a measuring tool.

Purpose: This study was done to construct a quality of life (QOL) model for recipients of a liver transplant. Method: In consideration of the main factors influencing QOL in recipient of liver transplants, a hypothetical model was constructed with 16 paths. A questionnaire was used to collect data from recipients of liver transplants who were being followed at one of 3 university hospitals. For the final analysis, there were 189 completed questionnaires and the hypothetical model was verified through covariance structure using LISREL program. Results: Overall fitness indices of hypothetical model were GFI= .99, AGFI= .97, NNFI= .96 and RMR=.020. After considering modification indices and paths that proved not to be significant and to improve model fitness, the hypothetical model was modified. In the final model, 3 paths from the hypothetical model were excluded. Overall fitness indices of the final model were GFI= .99, AGFI= .98, NNFI= .98 and RMR= .020. Eleven of fifteen paths proved to be significant. QOL was influenced by duration after transplantation, perceived health status, self-esteem, uncertainty, social support, self efficacy and depression and these variables explained 65% of the variance. Conclusion: This study presents a theoretical model for QOL for recipients of a liver transplant. Based on the results of this study and to improve QOL for recipients of a liver transplant, it is suggested that interventions to re-enforce self efficacy and self-help are needed.

Purpose: The purpose of this study was to identify factors influencing a family's quality of life (QoL) when one member has a liver transplantation. Methods: A total of 98 families were asked questions about characteristics, stress, social support and QoL. The instruments used for this study were the Stress Scale for Families of Liver Transplantation Recipients, the Personal Resources Questionnaire, the Korean version of QoL Simple Type Scale. Data were analyzed by t-test, ANOVA, Pearson's correlation coefficient and multiple regression. Results: The mean scores of stress was $2.58{\pm}0.75$ and of social support was $4.81{\pm}0.87$. The mean of the QoL was $3.39{\pm}0.60$. Quality of life had significant correlations with stress and social support. Using multiple regression analysis, the QoL was significantly influenced by social support, stress and monthly average household income. Conclusion: The results suggest that social support, stress and income should be considered in developing the nursing interventions to improve the QoL of families of patients with liver transplantation.

Purpose: The purpose of the study was to evaluate the effect of the immediate postoperative nutritional status and calorie adequacy on clinical outcomes in liver transplant recipients. Methods: A total number of 99 patients who received liver transplants were recruited from a tertiary university hospital. Demography, subjective global assessment, clinical outcomes and calorie adequacy were evaluated through personal interviews, electronic medical records and dietary records. Anthropometric measures, body mass index and percent of ideal body weight were also obtained. Results: At admission to the Surgical Intensive Care Unit (SICU), the triceps skinfold thickness and mid-arm muscle circumference were significantly lower in the malnourished group than in the well-nourished group (p<.05, respectively). In the clinical outcomes, transfusion of red blood cells, mechanically ventilated hours, length of stay in the Intensive Care Unit (ICU), length of stay in the hospital, and prothrombin time were significantly higher in the malnourished group than in the well-nourished group (p<.05, respectively). The mechanically ventilated hour was significantly higher in the group with less than 50% of their required energy intake (p<.05). Conclusion: Therefore, it is important to assess the nutritional status of immediate postoperative patients. Furthermore, studies on nutritional interventions are urgently needed to provide adequate nutritional care for patients in ICUs.

Purpose: The propose of this study was to introduce the clamping protocols for a biliary external drainage tube and trace the results of using clamping protocols to prevent some possible biliary complications or enable their early detection in living-donor liver transplantation. Method: This study was a retrospective study to analyze the cases of 97 subjects who had undergone liver transplantation in a hospital in Seoul, Korea. Clamping protocol 1 was applied to 47 patients, and clamping protocol 2 was applied to 50 patients. Results: In the case of protocol 1, the success rate of the clamping protocol was 74.5%, while that of protocol 2 was 84.0%. However, there was no significant difference in the compiled statistics from authentic sources (p = .246). Conclusions: The difference in the success rate between the two protocols was not significant for the clamping protocols of the biliary external drainage tube. However protocol 2 is suggested for the clamping method due to the simplicity of application. Further study with a large sample size is suggested.

Purpose: This study was designed to investigate the survey of analyzing nursing interventions and nursing outcomes of the patients with liver transplantation. Method: The subjects of this study consisted of 83 patients and fifteen nurses who took care of them. The methods of this study were retrospective and descriptive survey. Result: The mean age of patients was 42.7 years and the subjects were 62.7% males. 56.7% of these patients were diagnosed with liver cirrhosis of B type. The mean duration of hospitalization was 48.6 days. Ninety-five nursing interventions were performed at least daily. The most frequent used interventions were "environmental management: comfort", "medication administration: parenteral", "cough enhancement", and " oxygen therapy". Even though SGOT level to identify nursing outcomes was decreased, SGOT was not within normal limits. Therefore, even after discharge of patients, There is a need to take care of them carefully. Conclusion: These findings revealed the significance and need of nurse practitioners who performed professional nursing intervention for the patients with liver transplantation. Especially, it is necessary needs to develop the nursing intervention programs for comfort.

Purpose: This study was aimed to investigate the relationship between the level of stress and the quality of life among the adult recipients of living donor liver transplantation. Methods: Participants were 213 outpatients who received living donor liver transplantation at least 3 months prior to this study. Stress was measured using a modified version of the Kidney Transplant Recipient Stressor Scale (KTRSS), and the quality of life was measured using SF-36 version 2. Results: The mean of scaled stress level and quality of life of liver transplant recipients were $2.44{\pm}0.13$, $69.28{\pm}18.25$, respectively. There was an inverse correlation between those two parameters. Therefore lower stress could improve quality of life. Conclusion: For the liver transplantation recipients, improving the quality of life is to be the ultimate goal of health-related mediation. Liver transplantation recipients would need to cultivate self-care ability to manage stress, and improving their quality of life.

Purpose: The objectives of this study were to determine the prevalence, incidence, duration and risk factors for delirium following liver transplantation while the patients were in the acute stage and admitted to the intensive care unit. Method: A retrospective chart review of 106 patients who had liver transplantation was conducted. A delirium risk factor checklist was used, to collect preoperative and postoperative data. Descriptive analysis, t-test, x2-test, and logistic regression analyses were used for data analysis. Results: The post-transplantation incidence of delirium was 29.3% (n=31). Multivariate analysis revealed that risk factors were preoperative conditions in the patients including spontaneous bacterial peritonitis, hepatorenal syndrome, and postoperative laboratory test results, such as hyperbilirubinemia. Conclusion: Therefore, a daily delirium risk factor assessment should be conducted before liver transplantation as a way to identify risk of delirium after the liver transplantation and to effectively manage delirium when it occurs.
