    Local infiltration versus Laparoscopic e guided transverse abdominis plane block in laparoscopic cholecystectomy e double blinded randomized control trial
    (Elsevier, 2018) Siriwardana, R.C.; Kumarage, S.K.; Gunetilleke, M.B.; Thilakarathne, S.B.
    BACKGROUND: Transverse abdominal plane block (TAP) is a new technique of regional block described to reduce postoperative pain in laparoscopic cholecystectomy (LC). Recent reports describe an easy technique to deliver local anesthetic agent under laparoscopic guidance. METHODS: This randomized control trial was designed to compare the effectiveness of additional laparoscopic guided TAP block against the standard full thickness port site infiltration. 45 patients were randomized in to each arm after excluding emergency LC, conversions, ones with coagulopathy, pregnancy and allergy to local anesthetics. All cases were four ports LC. Interventions - Both groups received standard port site infiltration with 3-5ml of 0.25% bupivacaine. The test group received additional laparoscopic guided TAP block with 20ml of 0.25% bupivacaine subcostaly, between the anterior axillary and mid clavicular lines. As outcome measures the pain score, opioid requirement, episodes of nausea and vomiting and time to mobilize was measured at 6 hourly intervals. RESULTS: The two groups were comparable in the age, gender, body mass index, indication for cholecystectomy difficulty index and surgery duration. The pain score at six hours (P = 0.043) and opioid requirement at six hours (P =0.026) was higher in the TAP group. These were similar in subsequent assessments. Other secondary outcomes were similar in the two groups. CONCLUSION: Laparoscopic-guided transverses abdominis plane block does not give an additional pain relief or other favorable outcomes. It can worsen the pain scores

    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.
