Preservation of normal gastric emptying following gastric surgery by use of a muscle bridge

BACKGROUND: Maintenance of descending antral intramural pathways may be important in normal functioning of the pylorus after pylorus-preserving gastrectomy. METHODS: We examined the effect of a 1-cm bridge of muscle as a means of maintaining pyloric connection to antral intramural motor control pathways in 10 pigs. Antropyloroduodenal pressures and transpyloric flow were measured during gastric emptying of saline before and after either total …
