[Hemobilia after Menghini puncture].

In 100 patients before and after a percutaneous blind puncture of the liver after Menghini biliary juice was received with the help of a duodenal sound and this was investigated for blood admixtures microscopically and chemically. In 21 out of 100 punctures patients blood was proved in the duodenal juice: In 11 cases the proof of blood was positive before and after the puncture and in 10 patients only after the puncture blood was found in the duodenal juice. A macrohaemobilia was never observed. The influence of thromboplastin time, number of thrombocytes, time of haemorrhage, age and basic disease on the development and support of microhaemobilia was examined. In about 10% of the patients is to be reckoned with a microhaemobilia taking into consideration the indication and contraindication, also in exact performance of the blind puncture of the liver. However, the clinical importance is little in general.
