Abstract
Objective Peritoneal dialysis (PD) patients frequently suffer from dyspeptic complaints such as nausea, vomiting, abdominal distension, early satiety, and anorexia. Gastroparesis might be, at least partially, a source of dyspeptic complaints in PD patients. The aim of the present study was to determine the influence of the presence and composition of dialysate on gastric emptying in PD patients. Design Prospective study. Setting Renal Division, Department of Internal Medicine, Ghent University Hospital, Belgium. Patients Sixty-one PD patients using different dialysate solutions, and 27 healthy volunteers. Main Outcome Measure Gastric emptying of solids was assessed by the 13C-octanoic acid breath test. Results Gastric emptying was impaired in PD patients, regardless of the composition of dialysate and even if tested with an empty peritoneal cavity. Gastric emptying was significantly slower when glucose-containing dialysate was compared to an empty peritoneal cavity, or when glucose-containing dialysate was compared to icodextrin dialysate. No difference in gastric emptying could be demonstrated between glucose-containing dialysate and dialysate containing a mixture of glycerol and amino acids as osmotic agent. Conclusions These findings suggest that the delay in gastric emptying demonstrated in the presence of peritoneal dialysate is not the consequence of a mere volume or pressure effect, but of the absorption of substrate substances with caloric and/or metabolic activity, such as glucose or glycerol and amino acids.
