Abstract

Background/Purpose: Gastric resection is an infrequent surgical procedure in childhood. However, the use of the stomach for bladder augmentation and substitution is well documented. Partial gastrectomy performed in gastrocystoplasty (GCP) involves the greater curvature of the stomach, the same area in which gastric pace-maker cells are known to be placed. The aim of this study was to assess, by electrogastrography (EGG), if subtotal gastric resection can alter gastric motility in children submitted to partial gastrectomy for GCP. Methods:Gastric electrical activity (GEA) was evaluated in 25 children using EGG: 10 patients (4 boys, 6 girls; mean age, 11.6 years) previously submitted to GCP, and 15 normal subjects (12 boys, 3 girls; mean age, 8.62 ± 2.77 years) as controls. All patients were submitted to cutaneous EGG; recording GEA for 30 minutes before and after a standard test meal. The percentage of 3 cycles per minute (3CPM), bradygastria, tachygastria, DFIC (dominant frequency instability coefficient), DPIC (dominant power instability coefficient), PDP (period dominant power), PDF (period dominant frequency) were recorded and analyzed using Wilcoxon matched-pair test. Data were considered statistically significant if P <.05. Results: Normal subjects as well as operated patients showed a statistically significant difference in bradygastria (P = .05), PDP and PDF (P = .05) percentage, comparing pre versus postprandial period. In the normal group, 3CPM (P = .0012) and DFIC (P = .0008) were statistically different between the pre- and postprandial period. Patients who underwent GCP did not show any statistically significant difference in 3CPM and DFIC pre- and postprandial. Conclusions: In normal subjects, GEA showed a complete variation after the meal, whereas in operated patients GEA was impaired and only partially modified after the meal. This observation suggests that in patients with gastric resection, adaptation of the stomach to food ingestion is present but incomplete with respect to normal subjects; it can be caused by surgical removal of the pace-maker cells of the greater-curvature. For this reason a follow-up analysis of gastric function is recomended for all patients undergoing GCP.
