Abstract
The results obtained by the examination of the post-operative bile viscosity behaviour sampled by T-drainages of 29 patients (investigations of the relative viscosity with the help of a modified horizontal capillary viscometer from the day of operation until the 9th postoperative day) confirm the importance of the biorheological classification of bile fluid as a Maxwell fluid (investigations of the absolute dynamic viscosity of 33 bile specimens with a Contraves-Low-Shear-Viscometer and representation of flow curves for rheological characterization). The Maxwell flow behaviour is characterized--among other things--by an exponential increase in the case of prestasis. This fact is important in all "low-flow-states" of different pathophysiological genesis and offers a concept with respect to a pathogenetically orientated cholelithiasis prophylaxis.
