Lucy Adkinson Case history Reminder of different causes Update on recent NICE guidance Joe Locally advanced pancreatic cancer Admission February for pain control Whilst inpatient accumulating ascites Trial diuretics with no improvement Paracentesis performed Discharged home on increased diuretics 2 weeks later readmitted with tense ascites again BRI for PleurX ascitic drain insertion Ascites 75% cirrhosis 10% malignancy 3 % heart failure 2% TB Estimated problems associated with ascites present in 3.6 – 6% of hospice inpatients Two principal mechanisms in malignant ascites divided into transudates and exudates Transudates Low protein Exudates High protein Multiple hepatic mets or single large tumour causing Budd-chiari syndrome ? Increased vascular permeability Increased hepatic venous pressure Fluid leakage into Increase in plasma renin conc and peritoneum from thus salt and water sinusoids retention Indicative of portal hypertension Similar to cirrhosis Peritoneal tumour deposits and tumour neovasculature = leaky Extravasation of fluid BUT Ascitic fluid can also arise from unaffected peritoneum: Observed marked neovascularisation of peritoneum in malignant ascites and ovarian ascites - ? Cytokine and VEGF in ovarian cancer related leaky capillaries Complication of retroperitoneal tumour spread or its treatment Either due to damage of lymphatic vessels or obstruction of lymphatic flow through lymph nodes or pancreas Serum-ascites albumin gradient= serum albumin (same day) – ascites albumin High gradient “transudate” > 11g/l Indicative of portal hypertension Important because can help assess the likelihood response to diuretic therapy with aldosterone antagonist In malignancy role is controversial and slim evidence base BSG Guidelines on management of ascites in cirrhosis 9 observational studies 6 were case series 10+ patients 1 qualitative case series 3 case reports N = 40 (pleurX) assessing treatment complication rates compared with large volume paracentesis Complications same for both types Infection n=1 Leakage n=1 Loculations n=1 N=27 working at death but 11 lost to follow up 34 patients over 12 weeks (or death) 100% technical success 2 catheters needed to be removed Infection n=2, loculations n=14, leakage n=7, dizziness n=5, SOB n=1 Mean number of drainage sessions 23.3 28% performed by patient, 58% by carer Improved QoL at 12 weeks 28% respondents 50 patients 8 complications 100% patency at death Per pt PleurX IP paracentesis OP paracentesis £2466 £3146 £1457 • Saving of £679 per patient in comparison with inpatient paracentesis •7.4 hospital days saved per patient •23.5 more community nurse visits Different causes of ascites in malignancy If diuretics don’t work +/- ascites reaccumulates after paracentesis consider referral for pleurX ascitic drain (via oncology in BRI for costing)
