[Motility of antrum, pylorus, and duodenal bulb: importance of radiologic series analysis in man].
Arch Int Physiol Biochim Biophys. 1991 Dec; 99(6):429-34.AI

Abstract

The quantification of gastroduodenal motility uses invasive methods. The aim of our study was to further characterize the contractility of antrum, pylorus and duodenal bulb in two states, using a new, non invasive fluorographic method. Healthy volunteers (mean age = 28) were involved in this study under fasting conditions (n = 20) and after a meal (n = 20). In both conditions, the subjects have swallowed 250 ml of a barium sulfate solution for fluoroscopic gastrographies taken every 2 seconds, during 30 s. Spot films were analysed using a graphic table and locally developed microcomputer program to generate space-time diagrams of antral and duodenal areas and of pylorus diameters. For each subject, the antral CA, duodenal CB contractilities (maximal variation of antral, duodenal areas in p 100) and pylorus contractility CP (closure during the observation time in p 100) were calculated. CA values were high in the two situations, but did not differ (81.1 p 100 vs 82.5 p 100 post-prandial). In contrast, CP was higher under fasting (54.0 p 100) than in post-prandial (15.0 p 100; p less than .001). Two pyloric motor patterns were observed in post-prandial: A--pyloric contractions in relation with the end of antral contraction B--augmented pyloric resistances observed during the end of antral contraction and also associated with duodenal contractions. CB was low in post-prandial (27.0 p 100) compared to fasting CB (50.8 p 100; P less than .001). This method is reproducible and simple to use. It allows quantification of contractility and coordination in the antrum, pylorus and duodenal bulb. It may be useful to assess gastroduodenal motility under pathological conditions.
