Abstract

We evaluated gastric emptying time(GET) by using Tc99m-sulfur colloid gastric emptying scintigraphy in 11 patients with CAPD(6 male, 5 female) and 14 healthy volunteers. We investigated the effect of dialysate dwelling on GET by studying twice, once without dialysate in the abdomen(drained) and once with 2 L of dialysate in the abdomen(full), and the relationship between body surface area(BSA) and delayed gastric emptying. 1) The mean of gastric emptying rate in 120 minute in patients with CAPD when drained(67.8±13.4%) was not different from that in healthy volunteers(65.4±8.6%) 2) The mean of gastric emptying rate in 120 minute when full(55.6±14.6%) was significantly lower than that when drained(67.8±13.4%)(P<0.05). In four of the 11 patients(36.4%), gastric emptying was extremely delayed from normal to abnormal range when full. 3) The BSA(1.5±0.11m2)of patients who had extremely delayed GET from normal to abnormal range was smaller than that(1.74±0.22m2) of patients who had minimal delayed or unchanged GET when full. This study showed the patient with CAPD had normal gastric emptying when drained, and that gastric emptying was delayed by dialysate dwelling, especially in the patients who has less than 1.5m2 of body surface area. Therefore, we suggest that intermittent nocturnal peritoneal dialysis or a small volume of dialysate may be considered for the patient with small body surface area based on the adequacy.
