Item The long-term impact of postcholecystectomy major bile duct injury on liver stiffness(BioMed Central, 2024-11) Jayasekara, A.; Tillakaratne, S.B.; Dasanayake, U.; Gishanthan, S.; Siriwardana, R.C.INTRODUCTION Iatrogenic bile duct injuries (BDI) are a devastating complication. Long-term impact of corrective hepaticojejunostomy (HJ) for such injuries on post -surgery liver stiffness is lacking. Hence the aim of this study was to explore the extent of hepatic fibrosis in a cohort of patients with Strasberg E bile duct injuries who underwent HJ after a minimum follow-up of six months.METHODS Out of 50 BDI presented over a period of 10-years, 19 patients with Strasberg type E, injuries that underwent HJ and completed a minimum 6-month follow-up [65.5 (7 -108)] period were selected. Data were prospectively collected on liver functions and liver stiffness was assessed using a Fibroscan. Their liver stiffness and degree of fibrosis was compared with (n = 38) age, gender and comorbidity matched controls.RESULTS The median age was 47 (30-70) years, with 63% females. Primary HJ was performed in 84%, with a median time from injury to HJ of 7 (1-39) days. The total bilirubin was 16.5 (11.2) µmol/L, Alkaline Phosphatase was 102 (27.2) U/L, and Platelet count was 256 (77) x 103. Liver stiffness (median 6.4 kPa) did not significantly differ from controls (5.3 kPa). Fibrosis assessment revealed comparable distribution of F0 to F3 fibrosis between the study and control groups (F0/F1: 68.4% vs. 84.4%, F2: 10.5% vs. 9.4%). However, all three patients with right hepatic artery injury (p = 0.003) and three of five patients with bile duct stricture had F3/F4 fibrosis.CONCLUSIONS Major BDI repair demonstrates comparable liver fibrosis in the absence of artery injury and anastomotic strictures. Measuring liver fibrosis could be valuable in the presence of arterial injuries or anastomotic strictures.Item Image guided naso-jejunal tube placement in paediatric liver transplant patients in low resource settings: Feasibility, technique, and outcome(Sri Lanka College of Paediatricians, 2024) Appuhamy, W.N.D.P.C.; Fernando, M.; Tillakaratne, S.B.; Gunathilake, M.B.; Ganewatte, E.; Gishanthan, S.; Jayakody, R.D.C.G.; Siriwardana, R.C.No abstract availableItem A prospective study on drain fluid amylase as an indicator of clinical outcome in patients undergoing Whipple surgery(Sri Lanka Medical Association, 2023) Gishanthan, S.; Tillakaratne, S.; Bulathsinhala, B.S.K.; Uragoda, B.; Siriwardana, R.C.INTRODUCTION: Post-Whipple pancreatic fistula is defined as having a high drain fluid amylase (DFA) (>3 times of normal value). In our observation, DFA levels did not influence the clinical outcome. OBJECTIVES: To determine the drain fluid amylase levels on the outcome of patients METHODS: 48 patients who underwent the Whipple procedure from May 2015 to September 2019 were included. Serum amylase and DFA levels were assessed on days 1,3 and 5. Amylase levels were compared with the patient’s outcome and the nature of the pancreas. RESULTS: 20 patients had DFA over three times on day 1. Their median hospital stay (HS) and ICU stay did not differ from others (HS 8 vs. 9 days, p=0.545; ICU stay 3 vs. 3 p=0.95). On day three 15 patients had DFA rise and their hospital stay (HS) and ICU were comparable. (HS 8 vs. 9 days (p=0.083), ICU stay 3 vs 3 p=0.26). On day five 5 patients had DFA over three times and their median hospital stay (HS) and ICU stay were similar. Nature of the pancreas also did not correlate significantly with DFA more than 3 times. Although patients with DFA more than 3 times of normal value on day 1,3, and 5 had smaller duct diameter (D1 2.78mm vs 4.25mm p=0.86; D3 2.08mm vs 4.42mm p=0.165; D5 4.10mm vs 1.86mm p=0.44) non was statistically significant. CONCLUSIONS: DFA > 3 times on Day1,3 and 5 did not significantly alter the outcome of patients.
