Fig. 1 Gastroduodenal motility tracing, demonstrating simultaneous, prolonged contractions during fasting (left panel) and postprandial (right panel) phases. Contractions were present in duodenum but not in proximal jejunum (bottom tracing), a suggestion of mechanical obstruction in distal duodenum or proximal jejunum. Recording speed, 0.25 mm/s.
