Gastric motility measurement by magnetic resonance imaging and ultrasonography

The aim of this study was to evaluate the usefulness of magnetic resonance imaging (MRI) and ultrasonography (US) to measure gastric motility in patie nts subjected to laparoscopic assisted distal gastrectomy without preservat ion of the pylorus (LADG, n = 10) or laparoscopic assisted pylorus-preservi ng gastrectomy (LAPPG n = 10) was for: gastric cancer. Gastric emptying was achieved significantly earlier in patients who underwe nt LADG than in those who underwent LAPPG. Postoperative gastric motility w as significantly better in patients who underwent LAPPG than in those who u nderwent LADG as determined by both MRI and US.
