Abstract
It is known that chronic renal failure patients are assotiated with strutural and functional abnormalities of the gastrointestinal tract.
This study was carried out on twinty patients with chronic renal failure on maintenance haemodialysis and ten healthy persons as a control group (Volunteers). These patients were selected from Dialysis Unit, faculty of Medicine, Mansoura and Benha University hospitals.
These patients were (6) females and (14) males. age of patients range from 22 - 56 and means ± SD of the age of Patients (35.2 ± 12.6) while for control 21 - 52 years. means ± SD is (35.3 ± 12.6) and means ± SD of duration of dialysis for patient (34.5 ± 30.3).
All patients are subjected to Hb concertration, blood urea, serum creatinine and serum electrolytes before and after haemodialysis .
All control subjects and patients (before and after haemodialysis) are subjected to electrogastrography to reporte the myoelectrical activity of the stomach.
EGG before haemodialysis :
Fifty percent (50%) of cases (10 patients) before haemodialysis have abnormal electrogastrography while the other patients (50%) showed normal EGG.
The abnormalities of EGG before haemodialysis were in the form of tachygastria in (6 cases) (30%).
Means ± SD of tachygastria before Haemodialysis is (19.39 ± 13.37) and dysthythmia in 4 cases (20%).
EGG after Haemodialysis :
After haemodialysis number of patients with normal EGG is increased to become 17 cases (85%), whlie abnormal cases regress to become 3 cases only ”15%” (Tachygastria in two cases ”10%” and bradygastria in one case ”5%”).
