Abstract/OtherAbstract:
Alterations in gastric emptying are considered contributory to many sequelae of peptic ulcer surgery. The application of a validated method of firmly tagging solid food has enabled the measurement of the rates and patterns of gastric emptying in normal subjects, subtotal gastrectomy, and vagotomy and pyloroplasty (V&P). Normal persons emptied with a linear pattern at a mean rate of 27.96% per hr. Subtotal gastrectomy patients showed up to three phases in their emptying pattern, which, over all, approximated an exponential pattern with a mean rate constant of 0.030 min-1 and calculated t1/2 of 23.3 min. V&P subjects divided into two groups: (1) slow emptying with a linear pattern and mean rate of 17.64% per hr; (2) rapid emptying with exponential pattern and mean rate constant of 0.039 min-1, t1/2 of 17.7 min. The slow gastric emptying rate and slow passage of chyme through the small intestine in one-half of the V&P group presumably allows greater efficiency of digestion and absorption and may account for the over-all less severe nutritional disturbances after V&P.
