Esophageal Dysmotility in Chronic Hemodialysis Patients After Ingestion of Liquids With Different Viscosities
Abstract
Methods: Fifteen controls and nine asymptomatic CRF patients underwent esophageal manometry with dry swallows, swallows of 5 mL of water (1 centipoise) and 5 mL of sugar cane syrup (24500 centipoise). CRF patients were compared with controls for esophageal motility parameters, considering each type of swallow (dry/water/syrup).
Results: CRF patients had: tendency for higher lower esophageal sphincter (LES) resting pressure (P = 0.09); shorter LES relaxation duration after dry/water/syrup swallows (P = 0.0001, P < 0.0001, P = 0.0001, respectively); higher amplitude of proximal contractions after dry/water/syrup swallows (P = 0.008, P = 0.01, P = 0.04); tendency for longer duration of distal contractions after dry/water/syrup swallows (P = 0.07, P = 0.04, P = 0.09); lower velocity of distal contractions after dry/water/syrup swallows (P = 0.006, P = 0.09, P = 0.02); and higher incidence of multi-peaked contractions after dry/water/syrup swallows (P = 0.03, P = 0.0001, P < 0.0001).
Conclusions: Esophageal motility dysfunction can be a sub-clinical manifestation in CRF patients. Data also showed that swallows of a highly viscous liquid did not help to detect minor esophageal dysmotility in these patients.
