✦ Synopsis

Disturbances of intestinal motility, bacterial overgrowth and pancreocibal asynchrony are frequent findings in patients after Roux-en-y reconstruction (RYR). In dogs (n = 6) electromyographic recording of motility after partial gastrectomy with Roux-en-y reconstruction revealed no significant differences from controls in the Roux limb. However, changes in intestinal motility were extensively in the blind loop. The electromyographic pattern was characterized by an extreme loss of activity in the fasted and postprandial state. The activity front of the migrating motility complex occurred only in 25 % of the fasting studies and was not correlated in time with motility patterns of connected small intestine. Food intake led to a significant increase in the motility index in the Roux limb (60.2 + 10.5), but not in the blind ending loop (27.8 + 4.1). Pharmacological stimulation of the hypomotile blind loop with cisapride is successful: increase of the motility index to 111.2 _ 16.5. It might be useful in the treatment of symptomatic patients after RYR.
