Bacteriaemia after injection sclerotherapy of oesophageal varices.

Thirty consecutive alcoholic patients with biopsy-proven cirrhosis of the liver and oesophageal varices underwent a total of 47 upper intestinal endoscopies. During 31 of the endoscopies paravariceal sclerotherapy of oesophageal varices was performed. Blood cultures were drawn before and after the procedures. Bacteriaemia after endoscopy was detected on seven occasions: six after sclerotherapy and one after endoscopy without sclerotherapy. This difference did not reach statistical significance. The microorganisms cultured belonged to the normal flora of the skin or the oropharynx. Bacteriaemia was transient and had no clinical consequences.
