Background/Aims: Radionuclide esophageal transit study(RETS) has been proposed as a screening test for esophagea] motility disorders. However, ]ittle attention was paid to the esophageal transit patterns in various esophageal motility disorders. In the present study, we have compared the results from esophageal manometry and transit studies. Methods: Ninety six pantients with esopha- geal symptoms and 20 subjects without any known esophageal symptoms or disease were included. The results of RETS were divided into the following 3 patterns: normodynamic(ETT --15 sec), hypodynamic(lS ETT:- 300 sec). Within the group of patients with the hyp<xlynamic patterns, the transit curves were divided into 3 types: slope type, staircase type and another type. Results: Esophageal transit pattern in normal controls was smooth uninterrupted transit of bolus down the esophagus with mean ElT of 8.5 L6.5 seconds. Esophageal transit patterns in patients with es<ophageal symptoms were adynamic pattern(]2 achalasia, 1 seleroderna esophagus, I MEMD), normodynamic pattern(l9 NEMD), HLES(l diffuse esophageal spasm nutcracker esophagus), hypodynamic-staircase type(6 diffuse esophageal spasm, 3 NEMD). Hypodynamic-slope type(l9 NEMD), 3 HLES, 2 normal, 1 diffuse esophageal spasm, 1 nutcracker esophagus) and hypodyna- mic-other type(5 NEMD), 2, nutcracker esophagus, l. diffuse esophageal spasm, J. scleroderma esophagus, 1 normal). Conclusions: Normal subjects exhibited normodynamic patterns, whereas most of the achalasia patterns exhibited adynamic patterns and patients with diffuse esophageal spasm exhibited the various patterns of esophageal which suggest that this group has heterogenous motility abnormalities.
