Résumé
BACKGROUND: The pathophysiology of non ulcer dyspepsia is poorly understood. Data on gastrointestinal motility alterations in this condition in the Indian population are scanty. We studied esophageal and gastric motility in patients with non ulcer dyspepsia. METHODS: 58 consecutive patients with non ulcer dyspepsia (according to the Rome criteria) were studied; 10 healthy volunteers were studied as controls. Esophageal transit of solid and liquid boluses (in all patients) and solid-phase gastric emptying (in 20 patients) were studied using scintigraphic techniques. RESULTS: Delayed esophageal transit and delayed gastric emptying were observed in 32 (55%) and 9 (45%) patients, respectively. Delay of both esophageal and gastric transit was found in 5 patients. Mean (SD) esophageal transit for liquid bolus was significantly delayed in patients (9.3 [3.7] s) compared to controls (7.0 [2.0] s; p < 0.01). Mean (SD) gastric emptying time (T50) was significantly delayed in patients (61.6 [13.6] min) compared to controls (50.0 [5.0] min; p < 0.001). Esophageal and gastric delayed transit was found in about two thirds of patients with dysmotility-like dyspepsia, but there were no significant difference in these abnormalities among different subgroups of dyspepsia. CONCLUSION: High prevalence of esophageal and gastric transit delay was found in non ulcer dyspepsia, particularly in the dysmotility subgroup.
