[Liver sonography and ultrasound-guided puncture of the gallbladder in pigs: new possibilities for the diagnosis of mycotoxicosis].
60 pigs representing all age groups (suckling pigs, weaner pigs, hogs, gilts and sows; thereof 37 females, 2 males, 21 castrated males) were examined by ultrasound of the liver and by ultrasound guided gallbladder puncture. The visibility of the liver and gallbladder was strongly influenced by the size of the animals. The thickness of the abdominal and thoracic walls in older animals proved to be a highly ultrasound-absorptive medium, which limited the ability to assess the underlying tissue structures. As a result, gallbladder puncture of these animals was possible only with a certain degree of technical difficulty. The gallbladder puncture procedure itself posed little risk to the animal. The primary risk resulted from the general anesthesia required. Autopsy showed no pathological findings due to gallbladder puncture with the exception of minimal, rapidly healing, local infectious processes. The bile proved to be a suitable medium of the detection of mycotoxins and their metabolites. Selective accumulation of these toxins in bile provide a more reliable diagnostic tool than the standard mycotoxicological tests of feed.
