RESUMO
OBJECTIVES: The fregency of bacteremia after endoscopic variceal band ligation (EVL) is reported to be lower when compared to that after endoscopic variceal sclerotherapy (EVS). However, there are conflicting reports on the infectious sequelae after EVL. AIM: To compare the frequency on bacteremia and infectious sequelae after EVL and EVS in patients with cirrhosis of liver. METHODS: Bacteremia and infectious sequelae were studied in 32 sessions of EVL in 18 cirrhotic patients (Child-Pugh class A-6, B-5, C-7), 30 sessions of EVS in 22 cirrhotic patients (Child-Pugh class A-2, B-5, C-15) and 14 diagnostic upper gastrointestinal endoscopies. Blood cultures were collected before, during and 30 minutes after the procedure. Patients were observed for infectious sequelae during subsequent hospitalization. RESULTS: Before the procedure, bacteremia was present in 7/62 (11%) sessions. Significant bacteremia during and 30 min post-procedure developed in 8/32 (25%) and 12/30 (40%) of EVL and EVS sessions, respectively (p = ns), and in 1/14 (7%) upper gastrointestinal endoscopy sessions. There was more frequent bacteremia with severe liver disease (Child-Pugh class A-0/6, B-1/5. C-7/21; p = 0.09) in the EVL but not in the EVS group (Child-Pugh class A-1/3, B-2/5, C-9/22; p = ns). The incidence was higher with emergency sclerotherapy compared to elective sclerotherapy (6/8 [75%] vs 6/22 [27%]; p <0.01). One patient in the EVS group developed spontaneous bacterial peritonitis. CONCLUSIONS: Bacteremia occurs frequently following EVL and EVS in patients with advanced liver diseases. In the EVS group it is more common after emergency sclerotherapy. This bacteremia is rarely associated with significant infectious sequelae.
