Investigation of Helicobacter pylori colonization in adenotonsillectomy specimens by means of the CLO test.

Abstract

Investigation of Helicobacter pylori (HP) colonization in adenoid and tonsil tissues by using the CLO (Campylobacter-like organism) test. Prospective clinical study. Included in the study were 19 patients aged 4 to 38 who had undergone an adenoidectomy, tonsillectomy, or adenotonsillectomy procedure under local or general anesthesia. Tissue pieces with diameters of 2 mm, which had been obtained from each adenoid and tonsil specimens in the early postoperative stage, were placed in kits specially prepared for HP (CLO test). Color changes were noted after 20 minutes and after periods of 1, 3, and 24 hours. Eleven (57.89%) of the 19 patients included in the study were shown to be HP positive, and 8 (42.11%) were negative, regardless of the type of specimen. It was shown that there was a high rate of HP colonization in tonsil and adenoid tissues.
