INTRODUCTION: Biliary atresia implies high risk of mortality if not diagnosed and treated early. We undertook this study to assess the prognostic factors affecting the outcome of Kasai surgery.
METHODS: A retrospective clinical study was conducted among 58 patients from Hospital Sultanah Bahiyah Alor Setar. Data were analysed with logistic regression analysis using SPSS. Factors studied included age during surgery, bile duct diameter at the porta hepatic, race of patient, preoperative total bilirubin level and cholangitis. These factors were analysed to determine its significance as a prognostic factor affecting the outcome of Kasai surgery.
RESULTS: Older age group above 56 days of life, bile duct diameter at porta hepatis measuring <50μm, pre-operative total bilirubin >10mg% and cholangitis were found to be poor prognostic factors from univariate regression analysis. Variables having p value<0.025 were analysed using the multivariable regression analysis. Only age of patient and diameter of bile duct at the porta hepatis were eligible for this analysis. The final analysis showed that age 57 days of life and above (adjusted odd's ratio (aOR) = 9.412, p value = 0.042, 95% confidence interval (95%CI) = 1.079 to 82.104) and bile duct diameter <50μm (aOR = 13.812, p value = 0.016, 95%CI = 1.616 to 118.042) were significant factors affecting the outcome.
CONCLUSION: In conclusion, age of patient 56 days of life and younger and diameter of bile duct at porta hepatis ≥50μm gave a significantly better outcome after Kasai surgery.

Extrahepatic bile ducts constitute a significant anatomic site for surgeons when performing hepatobiliary
operations from minor procedure such as cholecystectomy to major operation such as hepatectomy. The
challenges for surgeon in performing such cases increase when congenital variance of biliary tree occurs which
may lead to unintentional bile duct injuries. We reported a case of a lady who presented with obstructive
jaundice secondary to huge distal common bile duct stone. The presence of right posterior segmental hepatic
duct, which rarely occurs, was discovered during intraoperative cholangiogram before common bile duct
exploration. The operation was successful without incidence of biliary duct injury.

Fulltext Biliary ascariasis and extrahepatic cholangiocarcinoma: a report of two cases

We report two cases of rural Malay women in Perak, Malaysia, with extrahepatic cholangiocarcinoma and coexistent biliary ascariasis. In both cases, the narrowed bile duct may have resulted in inability of the migratory nematode to return to the gastrointestinal tract. It may be reasonable, also, to postulate that chronic biliary tract infestation by Ascaris lumbricoides may have contributed to the development of cholangiocarcinoma; a situation similar to that observed in liver fluke infestation.

Fulltext Alteration of amino acid and biogenic amine metabolism in hepatobiliary cancers: Findings from a prospective cohort study

Perturbations in levels of amino acids (AA) and their derivatives are observed in hepatocellular carcinoma (HCC). Yet, it is unclear whether these alterations precede or are a consequence of the disease, nor whether they pertain to anatomically related cancers of the intrahepatic bile duct (IHBC), and gallbladder and extrahepatic biliary tract (GBTC). Circulating standard AA, biogenic amines and hexoses were measured (Biocrates AbsoluteIDQ-p180Kit) in a case-control study nested within a large prospective cohort (147 HCC, 43 IHBC and 134 GBTC cases). Liver function and hepatitis status biomarkers were determined separately. Multivariable conditional logistic regression was used to calculate odds ratios and 95% confidence intervals (OR; 95%CI) for log-transformed standardised (mean = 0, SD = 1) serum metabolite levels and relevant ratios in relation to HCC, IHBC or GBTC risk. Fourteen metabolites were significantly associated with HCC risk, of which seven metabolites and four ratios were the strongest predictors in continuous models. Leucine, lysine, glutamine and the ratio of branched chain to aromatic AA (Fischer's ratio) were inversely, while phenylalanine, tyrosine and their ratio, glutamate, glutamate/glutamine ratio, kynurenine and its ratio to tryptophan were positively associated with HCC risk. Confounding by hepatitis status and liver enzyme levels was observed. For the other cancers no significant associations were observed. In conclusion, imbalances of specific AA and biogenic amines may be involved in HCC development.

The liver is an important organ of the human body, playing a major role in the metabolism and storage of nutrients, synthesis of protein and other nutrients, as well as detoxifying many metabolic by-products. The response of the foetal and newborn liver to external insult and injury is limited. This is because the ability of the closely interdependent structures of a developing liver of expressing in the face of a variety of insults is limited as well. Thus most infants with insults to the liver present as cholestatic jaundice with variable degree of pale stools, enlarged liver and conjugated hyperbilirubinaemia. Biliary atresia, an idiopathic condition characterized by progressive fibrosing obliteration of both intra- and extrahepatic bile ducts, is the most important cause of neonatal cholestasis worldwide, including Malaysia. It is also the most important indication for childhood liver transplantation the world over. Challenges facing infants with biliary atresia include a delay in the diagnosis and late surgery, leading to a poor outcome. This often results from a failure to recognise the potential serious nature of an infant with prolonged cholestatic jaundice and pale stools among health care professionals.
