This study was undertaken to compare the effects of subtotal Billroth II gastrectomy on gastric emptying and gastrointestinal motility with previously published results in intact dogs and in dogs with subtotal Roux-Y gastrectomy. Extraluminal strain gauge transducers were used to study gastrointestinal motility after Billroth II gastrectomy in four conscious dogs. Gastric emptying was measured radiographically. In Billroth II dogs gastric emptying of low-viscosity meals was biphasic with an initial rapid emptying. The addition of nutrients to low-viscosity meals delayed gastric emptying accompanied with reduction in gastric and jejunal motility. Similar to that in Roux-Y dogs, gastric emptying of noncaloric medium-viscosity meals was delayed because of segmenting motor patterns of the jejunal loops, in contrast to the propulsive jejunal motor pattern in intact dogs. Nutrients added to medium-viscosity meals did not change the jejunal motor pattern; gastric emptying was delayed compared with intact dogs. Results show that meal viscosity and jejunal motor pattern influence gastric emptying after Billroth II gastrectomy.

UI	MeSH Term	Description	Entries
D007583	Jejunum	The middle portion of the SMALL INTESTINE, between DUODENUM and ILEUM. It represents about 2/5 of the remaining portion of the small intestine below duodenum.	Jejunums
D009119	Muscle Contraction	A process leading to shortening and/or development of tension in muscle tissue. Muscle contraction occurs by a sliding filament mechanism whereby actin filaments slide inward among the myosin filaments.
