OBJECTIVE: To investigate the relationship between dynamic change of electrogastrogram (EGG) with @entity1319 of antrum during migrating motor complex (MMC) cycle in @entity392 and @entity2210 , and to verify whether a 100% coupling of electrical and mechanical events existed after meal. METHODS: Eleven @entity392 ( @entity392 ) and 14 @entity1 with @entity2210 ( @entity2210 ) were studied. An 8-channel Dent-sleeve catheter was positioned under fluoroscopic guidance across antropyloroduodenal region and bipolar electrodes were attached to the skin corresponding to the location of antrum. Antropyloroduodenal pressure waves and electrical signals were transferred simultaneously to PC Polygraph ( @entity5939 ) and recorded for 3 hours preprandially and 2 hours after ingestion of 40 g solid meal (336 kJ). The power of EGG and @entity1319 ( @entity1319 ) of antral contractions were calculated as the area under curve (AUC) by a build-in computer program. RESULTS: The power increases of EGG increased significantly in phase II (P < 0.01), phase III (P < 0.01) and after meal (P < 0.01) compared with phase I in @entity392 , however, this dynamic increase was not found in @entity2210 . The power of EGG was positively correlated with the @entity1319 of antrum both in @entity392 (r = 0.87, P < 0.01) and in @entity2210 (r = 0.79, P < 0.01) during the interdigestive period. A significant increase of EGG power after meal was found in @entity392 , which corresponded to the degree of phase III and kept stable for the whole postprandial period. In contrast, power increase was not found in @entity2210 except during 30 min after test meal. CONCLUSIONS: Prolonged cutaneous EGG recording can reflect the periodic variation of @entity1139 cycle. EGG response in @entity392 but not in @entity2210 after meal is characterized as persistent increase which is corresponded to phase III.
