title: Risk of complications after abdominal paracentesis in cirrhotic patients: a prospective study.
abstract: OBJECTIVE
  Complications and technical problems of paracentesis in cirrhotic patients are infrequent. However, the severity and the incidence of these events and their risk factors have not been assessed prospectively.
  
  
  METHODS
  Cirrhotic patients (n = 171) undergoing paracentesis were included. Of the 515 paracenteses, 8.8% were diagnostic, and 91.2% were therapeutic. Technical features, demographic data, and adverse events during a period of 72 hours after the procedure were examined.
  
  
  RESULTS
  Major complications occurred in 1.6% of procedures and included 5 bleedings and 3 infections, resulting in death in 2 cases. Major complications were associated with therapeutic but not diagnostic procedures and tended to be more prevalent in patients with low platelet count (<50 10(9)/L), Child-Pugh stage C, and in alcoholic cirrhosis patients. Technical problems occurred in 5.6%. The most frequent complication was a leak of ascites at the puncture site (5.0%), and in 89.5% there were no complications.
  
  
  CONCLUSIONS
  The safety of paracentesis in cirrhotic patients might be decreased if risk factors, which depend on the characteristics of the patient and of the procedure itself, are present.
