AIM: In order to observe chemotherapeutic effect on electrogastrography, 21 postoperative patients were examined by electrogastrography before and after chemotherapy.
METHODS: Electrogastrography was recorded on epigastrium of patients in fasting state before and after chemotherapy.
RESULTS: Before chemotherapy, there were 10 patients with bradygastria and frequency range was 1.60 ± 0.85 cpm, 6 patients with dysrhythmia and after chemotherapy, there were 15 patients with bradygastria and the frequency range was 1.26 ± 0.73 cpm, 5 patients with dysrhythmia. The wave amplitude was lower after chemotherapy than that before chemotherapy.
CONCLUSIONS: (1) Electrogastrographic rhythm was lower and irregular after operation of stomach. (2) Electrogastrographic frequency and amplitude declined after chemotherapy, and this result showed that chemotherapy inhibits gastric motility.
