ABSTRACT
BACKGROUND: Patients with cirrhosis are at high risk of bacterial infections. Invasive procedures are generally believed to increase this susceptibility. AIMS: We investigated the incidence of bacterial infections in cirrhotic patients undergoing elective endoscopic variceal ligation (EVL). METHODS: We enrolled 60 consecutive cirrhotic patients who underwent a total number of 112 elective EVL procedures. One to seven bands were applied at each session until variceal eradication. Markers of inflammation/infection and blood cultures were obtained before and 24â¯h after EVL. RESULTS: Aetiology of liver disease was metabolic in 27 (45%), viral in 21 (35%), alcoholic in 12 (20%) patients. Child-Pugh class A/B/C distribution was 29/26/5, respectively, 23 (38%) patients had ascites and 15 (25%) had hepatocellular carcinoma. Blood cultures were negative in all samples before EVL, whereas 3/112 (2.7%) cultures tested positive after endoscopy. Streptococcus mitis and Staphylococcus epidermidis were isolated in 1 and 2 cases, respectively. None of these three patients developed any features of clinically relevant infection, suggesting that the positive cultures were an expression of a transient bacteraemia with no clinical sequelae. CONCLUSIONS: Bacterial infection is an uncommon occurrence after elective EVL in cirrhotic patients, and antibiotic prophylaxis is not necessary in this clinical setting.
