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.

Antibody-mediated rejection (AMR) is a major complication after ABO-incompatible liver transplantation. According to the 2016 Banff Working Group on Liver Allograft Criteria for the diagnosis of acute AMR, a positive serum donor specific antibody (DSA) is needed. On the other hand, the clinical significance of the histological findings of AMR in the absence of DSA is unclear. This paper describes a 57-year-old man (blood type, O+) who suffered from hepatitis B virus cirrhosis with hepatocellular carcinoma. Pre-operative DSA and cross-matching were negative. After transplantation, despite the improvement of the liver function, acute AMR was observed in the protocol biopsy on postoperative day 7; the cluster of differentiation 19+ (CD19+) count was 0% and anti-ABO antibody titers were 1:2. This paper presents the allograft injury like AMR in the absence of DSA after ABOi living donor liver transplantation with low titers of anti-ABO antibody and depleted serum CD19+ B cells.

Purpose: The purpose of the study was to understand the care experiences of the family of living donor liver transplantation (LDLT) patients where the donation had occurred within the family. Methods: Participants were eight family caregivers who cared for recipients and donors of LDLT. Data were collected through individual in-depth interviews from November, 2020 to April, 2021. Data analysis was performed through a cyclical process of data collection and analysis by applying Giorgi's phenomenological research method. Results: The five main components extracted from the experiences of the family caregivers were: "A double-edged choice to save the family", "The harsh daily life of liver transplantation care", "The yoke of double care on both shoulders", "The power to withstand the adversity of caring", and "The recovery and growth of life pursued by trusting each other". Conclusion: The participants tried to do their best in their daily lives, while providing reassurance and care to the LDLT patients in the family; however, they expressed some worry and hardship while doing so. The results of this study provide a deeper understanding of the caring experience of the family caregivers, which may contribute to the development of nursing interventions that will aid these caregivers in providing care to their LDLT family members. Furthermore, the development and application of an integrated management program for LDLT patients in the family is required.

This is a study to search for the ethical basis for valid informed consent of organ donors. It is an admirable action that a person give his own body part or organ as a gift to another person. The organ for transplantation can be removed only when the donor consents voluntarily to donation. It is recently proposed as the need for organ transplantation is increased that organs can be harvested although the consent of deceased cannot be obtained. This may raise many moral issues because human beings all have an unalienable right to control their own bodies. The principle of autonomy is usually regarded as an ethical basis for informed consent. However, some people criticize that the principle of autonomy requires a person and his decision to be autonomous (but there are many patients who aren't autonomous due to their confusion or unconscious condition in a clinical situation). or this principle can foster indifference to patients needing help: thus respect for principles of care and beneficence is necessary. When we consider the complexity of making a decision about organ donation. the principle of autonomy should be replaced by the principle of respect for individual autonomy. as expressed by Childress (1990). This principle requires the care givers to respect the client's individual decisions. The elements of informed consent are threshold elements: competence to understand and decide. voluntariness in deciding: information elements: disclosure of material information. recommendation of a plan. understanding of disclosure and recommendation: and consent elements: decision in favor of a plan. authorization of the chosen plan. In cases of living donors. the elements of competence and voluntariness are more important than the others. So only an adult can give a recipient his own body part. but it should be forbidden to harvest from minors or protected adults (i.e. developmentally disabled person However. when organs are removed from a cadaver donor. we ought to respect the donor's decision. So we ought to try to seek donor cards or any documents expressing the donor's opinion about organ transplant. All health care givers ought to disclose donor information about organ transplantation clearly enough for the donor to understand it and to be able to weigh the harms and benefits. We are going to propose 'the subjective standard' as the ethical standard of disclosure. This standard will assure that patients have enough information to be able to decide autonomously from their own position. Care givers have to consider the method of disclosure because donors can be influenced by it positively or negatively, Establishment of the Hospital Committee is recommended. because medical professionals will have a chance to discuss the procedure of decision and the validity of harvesting a organ from a person.

Background: Normal renal function and health have been recognized as important factors in living donors after kidney donation. The purpose of this study was to evaluate the health status and health-promoting lifestyle in living donors after kidney donation. Methods: A total of 678 living-kidney donors were counted in our center from January 1990 to December 2011. Only 84 donors agreed to participate in the survey by telephone. We received consent for participation in our survey from 48 donors (57.1%). Data were collected from May to August 2013 using donor characteristics, health status, and Health Promoting Lifestyle Profile I (HPLP-I). Results: The donors were predominantly female (62.5%) and the average age was 48.9±11.8 years, and the average period after nephrectomy was 9.7±5.7 years. The characteristics of donors included ideal body weight (37.5%), overweight (37.5%) in body mass index, and good health status (81.3%). Most donors underwent an annual medical check-up (56.2%), no health problem (81.3%), and no disease (64.6%). However, one patient was treated with dialysis for renal failure due to diabetes. The total average score for HPLP-I was 128.3±13.9. Higher than average scores (116.3±19.1) were observed for the general middle-aged woman. There were statistically significant differences in self-realization and nutrition in subsection of HPLP-I. Self-realization showed a higher score for Christian (F=2.743, P=0.041) and good health (F=3.389, P=0.017). Nutrition showed a higher score for overweight, obesity (F=6.783, P=0.000), and older than 60 (F=3.854, P=0.009). Conclusions: Most living kidney donors were healthy after their donation and had relatively high scores for health-promoting lifestyle. However, one patient had a serious health problem. In addition, younger, longer period after donation, and the rare health examination of donors showed a lower health-promoting lifestyle. Designed and continuous health-care management after transplantation is needed for kidney donors.

Purpose: Despite aggressive medical and nutritional management, patients with methylmalonic acidemia (MMA) often suffer from multi-organ damage. Early deceased donor liver transplantation (DDLT) has emerged as an intervention to prevent disease progression. We investigated the efficacy of living donor LT (LDLT) with a potential carrier of MMA and a small volume of graft in patients with MMA as an alternative to DDLT. Methods: Of five patients (three male, two female; median age 5.7 years; range, 1.3-13.7 years), four underwent carrier LDLT, while one underwent non-carrier auxiliary LDLT. All patients received pre- and post-LT continuous renal replacement therapy and were provided with minimal restriction diet according to serum MMA level after LT. MMA levels in the serum and urine, the incidence of metabolic crisis, and clinical findings before and after LT were compared. Results: The survival rate was 100% during 2.2 years of follow up period after LT. In all five cases, MMA titer in the serum after transplantation decreased with less restrictive diet. Metabolic crisis was not observed during the follow-up period. In addition, no patient showed progression of severe renal impairment requiring hemodialysis. Progression of delayed cognitive development was not observed. Social functioning with improved neuropsychiatric development was observed. Conclusion: This study showed that LDLT achieved improved quality of life with less restrictive diet, therefore it could be a feasible alternative option to DDLT for the treatment of patients with MMA, even with an auxiliary LT.

Purpose: Gracilis muscle free flap transplantation is chosen in the medium sized soft tissue defect and bone exposure from trauma and chronic osteomyelitis in the lower extremity. We set a study to search for gracilis free flaps to know whether symptoms were cured or recurred in patients that have passed over 10 years from flap transplantation. Materials and Methods: From August 1995 through September 2010, we have performed 28 cases of gracilis muscle free flap in the lower extremities. Ever since no case visited to demand any discomfort, breakdown or recurrence in the flap site on outpatient basis. We made a telephone call to patients or relatives documented in the medical record and only 2 cases visited outpatient department and 9 cases postponed the visit who satisfied with the final result but 17 cases had wrong telephone numbers. Causes, area of lower extremity, recipient vessels in the lower extremity, condition of the donor thigh and overall satisfaction of the flap transplantation in activities of daily living were investigated and written down in the medical record. Results: 11 cases were reviewed after average postoperative 13.7 years. Gracilis muscle flaps were not break down at the recipient site in all cases. The wound of donor thigh wound healed good and overall activities of daily living was satisfied in all cases. Conclusion: Gracilis muscle flaps which had performed and followed up average 13.7 years revealed confident in the medium sized soft tissue defect and bone exposure from trauma and chronic osteomyelitis in the lower extremity.

Purpose: Liver cancer, one of the most common cancers in China, is reported to feature relatively high morbidity and mortality. Curcumin (Cum) is considered as a drug possessing anti-angiogenic, anti-inflammation and anti-oxidation effect. Previous research has demonstrated antitumor effects in a series of cancers. Materials and Methods: In this study the in vitro cytotoxicity of Cum was measured by MTT assay and pro-apoptotic effects were assessed by DAPI staining and measurement of caspase-3 activity. In vivo anti-hepatoma efficacy of Cum was assessed with HepG2 xenografts. Results: It is found that Cum dose-dependently inhibited cell growth in HepG2 cells with activation of apoptosis. Moreover, Cum delayed the growth of liver cancer in a dose-dependent manner in nude mice. Conclusions: Cum might be a promising phytomedicine in cancer therapy and further efforts are needed to explore this therapeutic strategy.
