Epekövekben lévő baktériumok előfordulásának gyakorisága [The frequency of bacteria in human gallstones]

Abstract

Introduction: Complications caused by lost gallstones within the abdominal cavity are well known. Abscesses, perforation of the gastro-intestinal tract were all described in the literature, but gallstones were found in hernial sac, or even in sputum after it penetrated through the diaphragm into the respiratory tract. These complications can develop between several weeks to several years postoperatively. Most complications can be treated surgically only. Materials and methods: Fifty gallstones and bile samples were collected from 50 patients who underwent cholecystectomy (36 female / 14 male, avarge age: 60.8 +/- 6.8 years). All samples were sent for microbiological examination. Results: bacterial colonization of the gallstone and the bile were found in 16 cases. Four of them showed acute inflammation in the gallbladder while pathological signs of chronic inflammation in the gallbladder wall were detected in eight cases. Empyema was found in four cases. Bacteria from enteral origin (Esherichia coli, Enterococcus faecalis, Enterobacter cloacae) was detected in 13 cases, while non-enteral (Klebsiella penumoniae, Streptococcus alfa-haemoliticus) colony were detected in three cases. Positive bacterial cultures were identified in twelve female and fourmale patients. Conclusions: Different types of bacteria can be found in the gallstones, which may cause various complications.
