An enteric duplication cyst (EDC) is a rare congenital anomaly. Although EDCs can occur at any point throughout the gastrointestinal tract, they are most commonly reported in the ileum and only around 5-7% are of gastroduodenal origin. We report a case of a pyloric duplication cyst in a 3 hour old male with prenatal ultrasound showing a cystic mass. The patient had an abdominal ultrasound after birth that showed a mass with probable trilaminar wall. The diagnosis of pyloric duplication cyst was made in surgery and confirmed with histopathologic examination following resection. The patient is doing well with appropriate weight gain at follow-up appointments.

Gastrostomy tubes are often placed in patients with poor voluntary intake, oropharyngeal dysphagia, or chronic illness to provide definitive nutritional access. Despite the widespread use of gastrostomy tubes, some patients can experience complications associated with this procedure including gastrocolic-cutaneous fistula and dislodgement of gastrostomy tube. This case discusses an instance of gastrojejunal fistula formation over one year after gastrostomy tube placement likely due to tube dislodgement. Imaging showed gastrostomy tube traversing the posterior wall of the stomach and creating a fistula into the jejunum, with the balloon inflated within the jejunum. Gastrostomy tube was removed and replaced, with gastrostomy tube study showing no extravasation of contrast. Patient is now doing well-tolerating tube feeds at goal.
