title: [Interdigestive motility in duodenal diverticula].
abstract: In a controlled study of patients with cholelithiasis and patients with cholelithiasis and duodenal diverticula a significantly higher rate of bacteriocholia and miscolonization of the duodenum with intestinal bacteria as well as a significantly higher rate of interdigestive disorder of motility with missing of a wandering activity front was found in the group of patients with diverticula in 11 out of 25 patients. If a cyclic sober motility is found in patients with diverticula, the duration of cycle, the maximum pressure of the interdigestive complexes and its wandering speed are not significantly different from those of the control group. The studies allow the interpretation that retention of food in the diverticula is not the reason for the bacterial miscolonization of the duodenum and the biliary tract, but in patients with diverticula a disturbed self-cleaning mechanism is present. The pathogenesis of duodenal diverticula is not clear.
