IntroductionLarge-volume paracentesis (LVP) is the first-line treatment for decompensated cirrhosis with refractory ascites. While ascitic drain removal (ADR) within 72 hours of the procedure was once considered safe, it was uncertain whether ADR within 24 hours could further reduce the risk of ascitic drain-related bacterial peritonitis (AdBP). This study aimed to investigate the association between the timing of ADR and the presence of AdBP.MethodsAll patients with cirrhosis with refractory ascites who underwent LVP in our institution from 2014 to 2017 were studied. AdBP was diagnosed based on an ascitic fluid neutrophil count ≥ 250 cells/mm3 or positive ascitic fluid culture following recent paracentesis within two weeks.ResultsA total of 131 patients who underwent LVP were followed up for 1,806 patient-months. Their mean age was 68.3 ± 11.6 years, and 65.6% were male. Their mean Model for End-Stage Liver Disease score was 15.2. The overall incidence of AdBP was 5.3%. ADR beyond 24 hours was significantly associated with a longer median length of stay (five days vs. three days, p < 0.001), higher risk of AdBP (0% vs. 8.9%, p = 0.042) and acute kidney injury (AKI) following LVP (odds ratio 20.0, 95% confidence interval 2.4-164.2, p = 0.021). The overall survival was similar in patients who underwent ADR within and beyond 24 hours of LVP.ConclusionADR within 24 hours of LVP is associated with a reduced risk of AdBP and AKI. As AdBP is associated with resistant organisms and AKI, we recommend prompt ADR within 24 hours, especially in patients who have Child-Pugh class C alcoholic cirrhosis.Copyright: © Singapore Medical Association.
