Item Internal biliary diversion to avoid liver transplantation in an adult with intractable pruritus due to idiopathic intrahepatic cholestasis(Springer Nature, 2020) Siriwardana, R.C.; Jayatunge, D.S.P.; Ekanayake, C.S.; Tilakaratne, S.; Niriella, M.A.; Gunetilleke, B.; Dassanayake, A.S.BACKGROUND: Cholestasis is due to the obstruction at any level of the excretory pathway of bile. One particularly troublesome symptom of cholestasis is pruritus which leads to a profound effect on a patient’s quality of life. In children with progressive familial intrahepatic cholestasis (PFIC), medical treatment often fails. An alternative surgical procedure using biliary diversion offers significant relief for intractable pruritus in non-responders. CASE PRESENTATION: A 43-year-old male presented with a history of persistent jaundice and intractable pruritus for a 2-month duration. His liver enzymes were markedly elevated. However, his liver synthetic function was preserved. After extensive evaluation, a cause for cholestasis was not identified. A multi-disciplinary decision was to consider liver transplantation, but as his liver synthetic functions were remarkably preserved and the intractable pruritus was the sole indication for a transplantation, it was finally decided that internal biliary diversion should be done for symptomatic relief. His pruritus dramatically improved at 6 weeks post-operative. His liver enzymes and bilirubin levels also decreased compared to his pre-operative status. Currently, his liver functions are being closely monitored. CONCLUSION: Though it is not used in adults, the experience of biliary diversion in children with PFIC shows that there is a considerable improvement of symptoms and postpone the need for a transplant. In our patient, liver function and bilirubin as expected did not show a major improvement. But the dramatic improvement of the symptoms gave us the time to postpone the liver transplantation. A biliary diversion is a reasonable option that needs to be considered even in adults with refectory pruritus due to cholestasis.Item Factors affecting the clinical outcome of transarteriai chemo treatment for hepatocellular carcinoma in Sri Lankan patients(Sri lanka Medical Association, 2015) Jayatunge, D.S.P.; Siriwardana, H.D.R.C.; Niriella, M.A.; Dassanayake, A.S.; Liyanage, C.A.H.; Gunetilleke, M.B.; Upasena, A.; Sirigampola, C.; de Silva, A.P.; de Silva, H.J.INTRODUCTION AND OBJECTIVES: Transarterial-chemo-embolization (TACE) is used for palliation of unresectable hepatocellular carcinoma (HCC). We studied the tolerability of TACE in a cohort of patients with NASH and alcoholic cirrhosis related HCC. METHOD: Of 290 patients with HCC (July 2011 -December 2014), 84 underwent TACE. They were monitored for post-TACE complications: postembolization fever (PEF), nausea and vomiting (NV), abdominal pain, infection, acute hepatic decompensation (AHD) and acute kidney injury (AK1). RESULTS: 84 patients [90.5% males, 89.2% cirrhotics, 89.2% nodular HCC, median age 63(34-84) years] underwent 111 TACE sessions. All were Child class A [69.4% sessions (n=77)] or B; ascites and portal vein invasion was present in 18 (16.2%) and 15 (13.6%), respectively. 42 (38.2%) TACE procedures resulted in complications [PEF 28 (25.2 %), NV 4 (3.6%), abdominal pain 9 (8.1%), infection 7 (6.3%), AHD 13 (11.7%), AKl 3 (2.7%)]. There were no immediate post-TACE deaths. On univariate analysis elevated serum bilirubin (p=0.046) and low serum albumin (p=0.035) predicted PEF while low serum albumin (p=0.021) and low platelet counts (p=0.041) predicted AHD. In the multivariate model, factors with p<0.200 on univariate analysis and factors derived from the previous literature were considered covariates. Female gender (p=0.029, OR=1.412), ascites (p=0.030, OR = 1.212), elevated serum bilirubin (p=0.007, OR= 4.357) and large tumour size (p=O.Q36, OR=3.603) were independent risk factors for PEF. Tumour diameter >5cm (p=0.049, OR=2.410) and elevated serum bilirubin (p=0.036, OR=1.517) predicted AHD. CONCLUSION: In NASH and alcoholic cirrhosis related HCC patients pre-procedure serum bilirubin, ascites, tumour size and female gender predicted PEF post-TACE, Tumours>5cm with elevated bilirubin predicted AHD post-TACE.
