Gastrointestinal myoelectric activity in a child with gastroschisis and ileal atresia.
Gastroschisis is frequently associated with intestinal atresia and alterations in gastrointestinal function. The authors studied gastric and small bowel myoelectric activity in a child who had a complex course and prolonged inability to tolerate oral intake after staged repair of gastroschisis and an associated ileal atresia. The child remained unable to tolerate oral intake after repair of the atresia and was reexplored 3 months later to rule out a partial small bowel obstruction, with simultaneous placement of serosal electrodes on the stomach and proximal small bowel. Persistent gastric dysrhythmias were observed postoperatively, and the child was unable to tolerate gastrostomy tube feedings. Abnormalities were also seen in small bowel motility, including retrograde propagation of activity fronts of the migrating myoelectric complex. However, the intestine converted to a fed myoelectric pattern with tube feedings, and the child was subsequently able to tolerate feedings via a tube placed directly into the small bowel. The authors conclude that myoelectric recordings via implanted electrodes are safe and feasible in children, and may give information regarding underlying motility alterations. The ultimate clinical role of myoelectric recordings in treating children with suspected motility disorders will require further study.
