In rural areas, it is crucial that rural providers and transport teams are comfortable optimizing the gastroschisis patient in the immediate post-natal period prior to arriving at a hospital with pediatric surgical care.</div></div><div><h3>Case presentation</h3><div>A baby born at 32 weeks gestation in a remote Indian Health Services hospital was found to have gastroschisis at delivery. Transfer to the closest pediatric hospital, over 300 miles away, was initiated. While waiting for the NICU flight team to arrive, the rural hospital team cared for the infant. The bowel wrap caused the bedding to become cold and wet, and the baby was hypothermic when the flight team arrived. The local team started an IV, but was unable to achieve additional access and gave antibiotics instead of bolus or maintenance IV fluids. The infant arrived at the children's hospital over 6 hours after birth hypothermic, acidotic, and with severe bowel matting. At the receiving hospital, the gastroschisis was managed with a preformed silo and daily reductions until the baby was appropriate for surgical closure. Complete reduction of the bowel and surgical closure of the abdominal wall was achieved at day of life 15. A sutured repair of the fascia was performed. The baby recovered well from surgery and was started on feedings five days later.

Vital signs and laboratory testing were all within normal limits. Patient did not disclose a history of foreign body ingestion when he first presented. His initial physical exam was significant for mild left sided abdominal tenderness without any peritoneal signs. He was evaluated with a CT scan of the abdomen and pelvis, and to everyone's surprise, there was a string of round metallic objects present, resembling magnetic beads. Only at that time did the patient admit to ingesting magnetic beads that were purchased for his younger sister as a toy. He never disclosed the timing of the ingestion or the circumstance in which he ingested them. The CT scan did not demonstrate any free air or inflammation around the bowel loops that contained these beads. Since his abdominal exam was relatively benign and the CT scan did not reveal any concerning findings, we elect to obtain an abdominal X-ray at that time as a baseline with the plan to follow serial abdominal X-rays to track the progression of these beads throughout the GI tract. A repeat abdominal X-ray 6 hours later did not show any progression of the ingested beads, and his abdominal pain became more intense during the time of our observation. This prompted operative intervention via exploratory laparotomy. A periumbilical midline incision was made and the bowel loops were inspected. Intraoperatively, we observed that the magnetic beads have perforated through the jejunal wall with serosal inflammation of the adjacent bowel loop. We did not see any fistula between any bowel loops. Repair was accomplished via resecting the small bowel segment containing the perforation and primary anastomosis. The inflamed serosal layer at the adjacent loop was plicated with a series of Lembert sutures. The patient recovered well without complications.
