Abstract
Yolk immunoglobulin (IgY) is perfect supplement to mammalian immunoglobulin G in passive immune protection but with poor delivery stability. This work succeeded in pH-responsive oral delivery of IgY-Fab fragments with cellulose based multi-network composite hydrogels. Data displayed that the hydrogel 2 showed superior mechanical properties and load performance (encapsulation efficiency of 99.25% and loading capacity of 45.11 mg/100 mg). The stability of the released Fab was confirmed by HPLC with Fab purity up to 79.65% at the end of digestion. The FTIR spectra revealed the potential interactions between Fab and the hydrogel matrix of the formation of hydrogen bonds or electrostatic interactions between the groups of -OH, -CH2, and -COO-. The excellent rehydration of the hydrogels wouldn't be impacted by low-temperature freeze drying. In sum, this work is of great significance to the development of Fab-themed health-care food, intensive processing of poultry eggs and the economic construction of related industries.

Abstract
Wenchang chicken, a prized local breed in Hainan Province of China renowned for its exceptional adaptability to tropical environments and good meat quality, is deeply favored by the public. However, an insufficient understanding of its population architecture and the unclear genetic basis that governs its typical attributes have posed challenges in the protection and breeding of this precious breed. To address these gaps, we conducted whole-genome resequencing on 200 Wenchang chicken samples derived from 10 distinct strains, and we gathered data on an array of 21 phenotype traits. Population genomics analysis unveiled distinctive population structures in Wenchang chickens, primarily attributed to strong artificial selection for different feather colors. Selection sweep analysis identified a group of candidate genes, including PCDH9, DPF3, CDIN1, and SUGCT, closely linked to adaptations that enhance resilience in tropical island habitats. Genome-wide association studies (GWAS) highlighted potential candidate genes associated with diverse feather color traits, encompassing TYR, RAB38, TRPM1, GABARAPL2, CDH1, ZMIZ1, LYST, MC1R, and SASH1. Through the comprehensive analysis of high-quality genomic and phenotypic data across diverse Wenchang chicken resource groups, this study unveils the intricate genetic backgrounds and population structures of Wenchang chickens. Additionally, it identifies multiple candidate genes linked to environmental adaptation, feather color variations, and production traits. These insights not only provide genetic reference for the purification and breeding of Wenchang chickens but also broaden our understanding of the genetic basis of phenotypic diversity in chickens.

Abstract
Carbohydrates with different structures have metabolic differences in the human body, as well as individual differences. The present study aimed to investigate the effects of bacterial, short-chain fatty acids (SCFAs) and gas profiles of partially hydrolyzed guar gum (PHGG) on the fecal microbiota of 41 Chinese individuals by simulated fermentation in vitro. Results showed that PHGG stimulated the growth of Bifidobacterium and Faecalibacterium, inhibited the growth of Escherichia-Shigella, Klebsiella, and Dorea, and induced the production of fermentation gases (CO2, and H2) and SCFAs (acetic acid, butyric acid). Furthermore, Bifidobacterium was significantly increased in the young female and the old male-originated samples, while Klebsiella was significantly decreased in the old female ones after PHGG intervention, and there were also certain differences in gases and SCFAs among different population samples. These findings indicate that PHGG can modulate gut microbiota and metabolism well, whereas its use varies in different populations.

Abstract
The Muscovy duck (Cairina moschata) is an economically important poultry species, which is susceptible to fatty liver. Thus, the Muscovy duck may serve as an excellent candidate animal model of non-alcoholic fatty liver disease. However, the mechanisms underlying fatty liver development in this species are poorly understood. In this study, we report a chromosome-level genome assembly of the Muscovy duck, with a contig N50 of 11.8 Mb and scaffold N50 of 83.16 Mb. The susceptibility of Muscovy duck to fatty liver was mainly attributed to weak lipid catabolism capabilities (fatty acid β-oxidation and lipolysis). Furthermore, conserved noncoding elements (CNEs) showing accelerated evolution contributed to fatty liver formation by down-regulating the expression of genes involved in hepatic lipid catabolism. We propose that the susceptibility of Muscovy duck to fatty liver is an evolutionary by-product. In conclusion, this study revealed the potential mechanisms underlying the susceptibility of Muscovy duck to fatty liver.

Abstract
Domestic ducks are raised for meat, eggs and feather down, and almost all varieties are descended from the Mallard (Anas platyrhynchos). Here, we report chromosome-level high-quality genome assemblies for meat and laying duck breeds, and the Mallard. Our new genomic databases contain annotations for thousands of new protein-coding genes and recover a major percentage of the presumed "missing genes" in birds. We obtain the entire genomic sequences for the C-type lectin (CTL) family members that regulate eggshell biomineralization. Our population and comparative genomics analyses provide more than 36 million sequence variants between duck populations. Furthermore, a mutant cell line allows confirmation of the predicted anti-adipogenic function of NR2F2 in the duck, and uncovered mutations specific to Pekin duck that potentially affect adipose deposition. Our study provides insights into avian evolution and the genetics of oviparity, and will be a rich resource for the future genetic improvement of commercial traits in the duck.

Abstract
The objective of this study was to evaluate the effects of dietary linoleic acid (LA) on growth performance, antioxidant capacity, and lipid metabolism in pigeon squabs by supplementing LA in their parental diets. A completely randomized design that consisted of a control group, 1% dietary LA addition group (LA1%), 2% dietary LA addition group (LA2%), and 4% dietary LA addition group (LA4%) was used. Six squabs from each treatment were randomly sampled at the day of hatch and days 7, 14, and 21 after hatch. The results showed that parental dietary LA had no significant influence (P > 0.05) on body weight (BW) gain or relative organ weights (% of BW) in squabs. The activities of superoxide dismutase, catalase, and glutathione peroxidase in the LA1% were significantly increased (P < 0.05) compared with those in the control group. The malondialdehyde content in the LA1% was significantly lower (P < 0.05) than that in the control group. The levels of serum triglyceride in the LA1% and LA2% were significantly decreased (P < 0.05) compared with those in the control group, whereas the serum high-density lipoprotein cholesterol level in the LA1% and LA2% and the free fatty acid level in the LA4% were significantly higher (P < 0.05) than those of the control group. The activities of lipoprotein lipase, hepatic lipase, and hormone-sensitive lipase in the LA1% were significantly higher (P < 0.05) than those in the control group. The 3-hydroxy-3-methylglutaryl coenzyme A reductase activity in the LA1% and the hormone-sensitive lipase activity in the LA4% were significantly decreased (P < 0.05) compared with those in the control group. The mRNA expression of carnitine palmitoyltransferase 1, acyl-CoA 1, and peroxisome proliferator-activated receptor α was significantly upregulated (P < 0.05) in the LA1% compared with that in the control group. The Oil Red O staining area in the LA1% and LA2% was significantly reduced compared with that in the control group. The results indicated that although supplemental LA had negligible effects on growth and development in pigeon squabs, parental dietary LA at a concentration of 1% could have beneficial effects on maintaining squabs healthy as reflected by improved antioxidant capacity and lipid metabolism.

Abstract
Yolk ratio is an important production index in the salted duck egg industry. Yolk constituents are deposited during development of follicles. However, the molecular mechanism responsible for different yolk ratios in laying ducks remains elusive. In this study, Shaoxing ducks laying eggs with different yolk ratios were chosen for an analysis of liver and ovary transcriptome information. Twelve libraries were constructed and generated an average of 58.5 million clean reads per library, of which 69% of clean reads from liver and 65% of clean reads from ovary were mapped to a reference genome. Between cross-phenotype groups, a total of 250 and 230 differently expressed genes (DEGs) were identified in liver and ovary respectively, of which 101 and 50 DEGs respectively were characterized. Several DEGs were detected, among which HMGCS1, HMGCR, FDFT1, (DHCR7), (STARD4), CYP46A1 and LPIN3 are involved in cholesterol metabolism-related pathways; KIAA0319, STARD4, AP1S3, SH3GL2 and CAV2 are involved in vesicular transport in the liver; and ELOVL2 and PSD2 are involved in fatty acid elongation and endocytosis in the ovary. High yolk-ratio ducks had higher activity for cholesterol synthesis and molecular trafficking. The identification of candidate genes greatly advances the understanding of the genetic basis of the formation of different yolk ratios.

Abstract
AIM To investigate the specific biomarkers and potential pathogenesis of colorectal cancer-related ischemic stroke (CRCIS).
METHODS A retrospective study was conducted on CRCIS patients (colorectal cancer patients with ischemic stroke without conventional stroke risk factors) registered at seven centers between January 2007 and December 2017. Clinical data and laboratory and imaging findings were compared with age- and sex- matched patients with colorectal cancer (CRC) without ischemic stroke that were admitted to the same hospital during the same period. Univariate and multivariate analyses were performed to analyze the independent risk factors for CRCIS. A receiver operator characteristic curve was configured to calculate the optimal cut-off value of the products of the independent risk factors for CRCIS.
RESULTS A total of 114 CRCIS patients and 114 CRC patients were included. Multiple lesions in multiple vascular territories were common in CRCIS patients (71, 62.28%). The levels of plasma D-dimer, carcinoembryonic antigen (CEA), cancer antigen 125, and neutrophil count were significantly higher in CRCIS patients than in CRC patients. Multiple logistic regression analysis revealed that plasma D-dimer levels [odds ratio (OR) = 1.002, 95% confidence interval (CI): 1.001-1.003, P < 0.001], CEA levels (OR = 1.011, 95%CI: 1.006-1.015, P < 0.001), and neutrophil count levels (OR = 1.626, 95%CI: 1.268-2.087, P < 0.001) were independent risk factors for CRCIS. In addition, receiver operator characteristic curve revealed that the area under curve for the products of plasma D-dimer, CEA, and neutrophil count was 0.889 ± 0.022 (95%CI: 0.847-0.932, P < 0.001), and the optimal cut-off value for the product was 252.06, which was called the CRCIS Index, with a sensitivity of 86.0% and specificity of 79.8%.
CONCLUSION Hypercoagulability induced by elevated CEA and neutrophils may be an important cause of CRCIS. The CRCIS index, which serves as a biomarker of CRCIS, needs further study.

Abstract
Phosphoenolpyruvate carboxykinase 1 (soluble) (PCK1) is a key gene in gluconeogenesis and glyceroneogenesis. Although its functions have been extensively studied in mice, bats and humans, little is known in ducks. Here, PCK1 functions were studied using a duck domestication model and a 48-h fasting experiment. We found PCK1 expression significantly decreased in two breeds of domestic ducks (Jinyun Pockmark ducks and Cherry Valley ducks) as compared with wild ducks (Anas platyrhynchos). Simultaneously, plasma levels of glucose, triglycerides and free fatty acid in domestic ducks were lower than in wild ducks. When compared with fed ducks, the plasma triglyceride level was observed to be significantly decreased, while the glucose and free fatty acid levels remained constant in 48-h fasting ducks. The expression analysis of gluconeogenic genes revealed that fructose-1,6-bisphosphatase genes (FBP1 and FBP2) and the glucose-6-phosphatase gene (G6PC2) were not changed, whereas PCK1 was significantly upregulated. In addition, the reported regulators of PCK1, including forkhead box A2 (FOXA2) gene and orphan nuclear receptor NR4A family genes (NR4A1, NR4A2 and NR4A3), exhibited similar expression levels between 48-h fasting ducks and fed ducks, suggesting that PCK1 is not regulated by these genes in the duck under fasting conditions. In conclusion, PCK1 expression may affect plasma levels of glucose, triglycerides and free fatty acid during the duck domestication process. This work demonstrates for the first time in duck that PCK1 is a key gene in maintaining plasma glucose homeostasis during fasting and that the upregulated expression of PCK1 may be responsible for constant plasma free fatty acid level by the glyceroneogenesis process.

Abstract
Excessive adiposity is a major problem in the duck industry, but its molecular mechanisms remain unknown. Genetic comparisons between domestic and wild animals have contributed to the exploration of genetic mechanisms responsible for many phenotypic traits. Significant differences in body fat mass have been detected between domestic and wild ducks. In this study, we used the Peking duck and Anas platyrhynchos as the domestic breed and wild counterpart respectively and performed a transcriptomic comparison of abdominal fat between the two breeds to comprehensively analyze the transcriptome basis of adiposity in ducks. We obtained approximately 350 million clean reads; assembled 61 250 transcripts, including 23 699 novel ones; and identified alternative 5' splice sites, alternative 3' splice sites, skipped exons and retained intron as the main alternative splicing events. A differential expression analysis between the two breeds showed that 753 genes exhibited differential expression. In Peking ducks, some lipid metabolism-related genes (IGF2, FABP5, BMP7, etc.) and oncogenes (RRM2, AURKA, CYR61, etc.) were upregulated, whereas genes related to tumor suppression and immunity (TNFRSF19, TNFAIP6, IGSF21, NCF1, etc.) were downregulated, suggesting adiposity might closely associate with tumorigenesis in ducks. Furthermore, 280 576 single-nucleotide variations were found differentiated between the two breeds, including 8641 non-synonymous ones, and some of the non-synonymous ones were found enriched in genes involved in lipid-associated and immune-associated pathways, suggesting abdominal fat of the duck undertakes both a metabolic function and immune-related function. These datasets enlarge our genetic information of ducks and provide valuable resources for analyzing mechanisms underlying adiposity in ducks.

Abstract
In this study, chicken adipocytes were cultured to evaluate RNA interference by the leptin receptor gene. A small interfering RNA of the leptin receptor gene was synthesized, with a suppression rate of 60% being generated (P < 0.01). After the knockdown of the leptin receptor, the expression levels of certain genes decreased significantly; specifically, peroxisome proliferator-activated receptor γ, fatty acid synthase, adipose triglyceride lipase, and lipoprotein lipase. In addition, a significant increase in the expression of the adiponectin gene was documented. These results demonstrate that the leptin receptor gene might contribute to lipid metabolism by influencing the expressions of the peroxisome proliferator-activated receptor γ, fatty acid synthase, adipose triglyceride lipase, lipoprotein lipase, and adiponectin genes.

Abstract
Several studies have documented the process of early embryonic development in poultry; however, the molecular mechanisms underlying its developmental regulation are poorly understood, particularly in ducks. In this study, we analyzed differential gene expression of embryos 6 and 25 h following oviposition to determine which genes regulate the early developmental stage in ducks. Among 216 randomly selected clones, 39 protein-encoding cDNAs that function in metabolism, transcription, transportation, proliferation/apoptosis, cell cycle, cell adhesion, and methylation were identified. Additionally, the full-length cDNA of the Nanog gene, encoding a 302-amino acid protein, was obtained. Quantitative real-time polymerase chain reaction analyses were performed to detect expression levels of the selected genes during early and late embryonic stages, which revealed that these genes are expressed in a particular spatial and temporal pattern. These results indicate that these genes may play pivotal roles in the process of area pellucida formation through a complex and precise regulatory network during development in duck embryos.

Abstract
Previous studies have shown that the in ovo injection of equol can markedly improve the water-holding capacity of muscles of broilers chickens at 7 wk of age through promotion of the antioxidant status. We aimed to investigate directly the antioxidant effects of equol on muscle cells in broilers. Muscle cells were separated from leg muscle of embryos on the 11th day of incubation and treated with equol and H(2)O(2), either alone or together. Cells were pretreated with medium containing 1, 10, or 100 μM equol for 1 h prior to the addition of 1 mM H(2)O(2) for a further 1 h. Photomicrographs of cells were obtained. Cell viability, malondialdehyde (MDA) content, and L-lactate dehydrogenase (LDH) activity in the cell supernatant, as well as intracellular total superoxide dismutase (T-SOD) and glutathione peroxidase (GSH-Px) activities were determined. Treatment with 1 mM H(2)O(2) caused serious damage to cells, indicated by comets with no clear head region but a very apparent tail of DNA fragments. Pretreatment with low (1 μM) but not high concentrations of equol (10 μM) inhibited cell damage, while 100 μM equol caused more serious damage than H(2)O(2) alone. Pretreatment with 1 μM equol had no effect on cell viability, while pretreatment with 10 and 100 μM equol significantly decreased cell viability in a dose-dependent manner. Compared with H(2)O(2) alone, pretreatment with low-dosage equol markedly decreased LDH activity and MDA production in the supernatant, significantly increased intracellular T-SOD activity (P < 0.05) and tended to increase intracellular GSH-Px activity (0.05 < P < 0.1). Pretreatment with high-dosage equol (10 and 100 μM) significantly enhanced LDH activity, but had no effect on MDA content, T-SOD or GSH-Px activity induced by H(2)O(2,) except for an obvious increase in GSH-Px activity caused by 10 μM equol. These results indicate that equol at low dosage can prevent skeletal muscle cell damage induced by H(2)O(2), while pretreatment with high-dosage equol shows a synergistic effect with H(2)O(2) in inducing cell damage.

Abstract
1. The aim of this study was to identify the effect of perilla extract, a source of polyunsaturated fatty acids, on lipid metabolism and expression of lipid-related genes in livers of Shaoxing ducks. 2. Two hundred and forty 28-week-old laying ducks received a commercial diet with perilla extract added at 0 (control) or 200 mg/kg of feed. 3. Ducks fed on a diet with perilla extract had increased laying rates compared with control ducks. 4. Serum concentrations of triglycerides were reduced by perilla extract, while high-density lipoprotein cholesterol and total serum cholesterol increased. 5. The expression of genes involved in hepatic lipogenesis, sterol regulatory element-binding protein-1, acetyl CoA carboxylase, stearoyl CoA desaturase, fatty acid synthase, apolipoprotein B, and apolipoprotein very low density lipoprotein, were decreased in the perilla group. 6. The mRNA expression of peroxisome proliferators-activated receptor alpha and acyl-coenzyme A oxidase was enhanced following treatment with perilla extract, and a similar tendency was observed in the expression of liver fatty acid-binding protein. 7. The results show that a diet with 200 mg/kg perilla extract regulated fat metabolism of Shaoxing ducks by improving egg laying, altering serum lipid profiles, stimulating lipid catabolic gene expression and inhibiting lipogenic gene expression in the liver.

Abstract
Cholesterol 7α-hydroxylase (Cyp7a1) plays a crucial role in the synthesis of cholic acid and cholesterol catabolism. In this study, Cyp7a1 expression in goose liver was identified for the first time using differential display reverse transcription PCR. This study used real-time PCR and quantified the transcript levels of the cyp7a1 gene under different feeding conditions. In overfeeding, cyp7a1 expression by the liver was lower than that seen for normal feeding and the same result was observed for the Cyp7a1 protein level. The cholesterol level in serum and liver was higher in the overfed group. This study suggests that low-level expression of Cyp7a1 is associated with the formation of goose fatty liver.

Abstract
Several studies have investigated that linoleic acid (LA) and eicosapentaenoic acid (EPA) affect cell proliferation and lipid catabolic gene expression in mammals. To determine if LA and EPA increase duck cell proliferation and lipid catabolic gene expression, the authors exposed duck primary hepatocyte cultures to LA or EPA. The results showed that both LA and EPA increased cell proliferation in a dose-dependent manner (100 μM). The effect on specific cell-cycle phases was also studied; LA and EPA (100 μM) deceased the proportion of cells in the G0/G1 phase from 83 to 80.8 and 80.3%, respectively, concomitant with an increase in the proportion of S-phase cells (11.5 and 10.5 vs. 8%, respectively). The expression of PPAR-α and PPAR-α target genes, such as acyl-CoA oxidase (ACOX), lipoprotein lipase (LPL), liver fatty acid-binding protein (L-FABP), was examined by quantitative real-time PCR. The results showed that the expression of the PPAR-α, ACOX, and LPL genes increased significantly following LA and EPA exposure, but that the expression of L-FABP remained unchanged. This study provides the first characterization of LA- and EPA-induced cell proliferation and PPAR-α and PPAR-α target gene transcriptional responses in duck primary hepatocyte cultures.

Abstract
The effect of a phyto-oestrogen, daidzein, on the laying performance of Shaoxing female ducks was examined in three experiments performed at different stages of the egg production cycle. Egg-laying rate, egg weight, egg composition, feed conversion ratio, hatchability characteristics of eggs and body weight, ovary and oviduct weight, as well as changes in serum concentrations of T3, T4 and E2 were recorded as response criteria. In the first experiment, 68 young ducks, 100 d of age, were given a basal diet (maize-soybean meal) with or without 3 mg of daidzein/kg diet for 42 d. Daidzein did not affect the onset of lay but apparently decreased egg-laying rate and mean egg weight as well as the feed conversion ratio. In the second experiment, 240 breeding ducks, 402 d of age, were allotted at random to three groups and given the basal diet containing daidzein at 0 (control), 3 (Da1) and 5mg/kg (Da2) for 35d. Egg-laying rate, mean egg weight and feed conversion ratio increased in both Da1 and Da2 groups. However, an adverse effect of daidzein on fertility and hatchability was observed. In the third experiment, 320 breeding ducks, 415 d of age, were fed on the basal diet with or without 5mg of daidzein/kg diet for 63 d. Egg-laying rate increased by 7.7%, average egg weight tended to increase, whereas yolk/albumen ratio decreased. Daidzein-treated ducks had higher body weight and oviduct weight compared with their controls. Elevated plasma T4 and E2 concentrations accompanied these phenotypic changes, but serum T3 was not affected. It is suggested that daidzein exerts divergent effects on the egg-laying performance of Shaoxing ducks under different physiological conditions and this action is dose-dependent. The changes in circulating E2 imply possible participation of endogenous oestrogen in the mechanism of daidzein action.

Abstract
Eggshell has three colors: white, blue and brown. Chicken and duck eggs with blue eggshell have superior market for its better appearance, delicious taste, abundant nutrition and higher eggshell thickness and strength compared to those with white eggshell. However, error was often made when breeding blue-eggshell chicken or duck lines based on phenotypes. Studies on the forming and controlling mechanism of eggshell color had important theoretic and practical value. This review mainly discussed the types of eggshell color, its pigment composition and synthesis. Inheritance and heritability, genetic model, the number of genes, and the dominant-recessive relationship between genes for eggshell color were also reviewed. Information described in this review is useful for understanding the forming mechanism of eggshell color.

Abstract
This study was conducted to clone the prolactin gene (PRL) in Eastern Zhejiang White Geese and to investigate the PRL gene expression characteristics during egg-laying, out-of-lay and incubating periods by real time PCR. Comparisons were made respectively of concentration of prolactin mRNA in the hypothalamus, pituitary gland and ovary of the adult female geese at different reproductive periods. The result indicated that there were significant differences (P<0.05) in PRL mRNA expression between different reproductive periods of the geese. The lowest level of PRL expression was found in out-of-lay geese, higher in the egg-laying geese, and the highest in incubating geese. Furthermore, the analysis of PRL expression in different tissues indicated that the highest levels of PRL was expressed in the pituitary gland, followed in hypothalamus, and the least in ovary of the geese. There were significant difference (P<0.01) expression of PRL between the pituitary gland/hypothalamus and ovary of the geese, whereas no any difference was observed between the pituitary gland and hypothalamus (P>0.05). In summary, the PRL mRNA expression had variance in different reproductive periods of the geese.

Abstract
Chicken is a main poultry in China. Molecular breeding for disease resistance plays an important role in the control of diseases, especially infectious diseases. Choice of genes for disease resistance is the key technology of molecular breeding. The MHC is of great interest to poultry breeding scientists for its extraordinary polymorphism and close relation with traits of resistance against infectious diseases. The article gives a detailed introduction about the association of MHC gene polymorphisms with traits of resistance against infectious diseases in chickens and looks towards the future of application of MHC in molecular breeding of chicken for disease resistance.

Abstract
OBJECTIVE To investigate the prevention and treatment of biliary complications after orthotopic liver transplantation (OLT). METHODS OLT was performed in 18 patients with end-stage liver disease, including 6 patients with primary liver cancer. Except 1 patient was infused only through the portal vein, others were infused through the portal vein and hepatic artery of the donor. The biliary tract was reconstructed using choledochocholedostomic anastomosis in 17 patients, and using Roux-en-Y choledochojejunostomic anastomosis in 1 patient. RESULTS Four patients with biliary complication were found. In one patient, biliary leakage was found around the T-tube on day 14 postoperatively, and disappeared after re-opening of the tube. In one patient undergoing Roux-en-Y choledochojejunostomic anastomosis, biliary leakage was found on day 12 postoperatively and reoperation was performed. The T-tube was removed from the anastomosis after reoperation, and abdominal infection was controlled, but high fever recurred on day 49 postoperatively. The patient died on day 52 postoperatively. Autopsy revealed biliary leakage and biliary tract necrosis. In another patient, biliary leakage was found on day 3 after operation, and was treated by adequate drainage. Four months after operation, biliary sludge in the common tract was found and treated successfully with oral chemolysis. But biliary sludge or stone recur on one and half year after OLT. Spincterotomy and basket extraction were performed via endoscopic retrograde cholangiopancreatography, and the biliary sludge or stone was cleared out. In case 4, biliary drainage tube cholangiogram showed anastomotic stenosis one month after operation. Three months later, biliary sludge or stone was found beyond anastomotic stenosis. After oral chemolysis (ursodeoxycholic acid) and irrigation with heparinized saline solution via the biliary drainage tube, the biliary sludge disappeared. CONCLUSIONS To reduce the incidence of biliary complications, adequate infusion of the hepatic artery, complete slushing of the biliary tract, and reduction of injury to the blood supply of the donor biliary tract are essential. Most biliary complications can be treated successfully by non-operative treatment or minimally invasive operation.
