Pancreatic Pseudocysts (PPs) complicate 10-20% of pancreatitis, the majority of which are asymptomatic and do not require drainage. When drainage is indicated, PPs have conventionally been managed surgically. Since surgery is associated with high complication rates (35%) and mortality (10%), PPs have increasingly been managed with less invasive techniques. Percutaneous drainage and indwelling catheters have both been associated with high recurrence rates. Therefore, endoscopic ultrasound-guided transmural drainage has become the best modality to drain peripancreatic fluid collections (PFCs). Most cases of PFC drainage in the literature involve adults. We describe a 3 year old with a PFC that was drained using a lumen-apposing metal stent (LAMS). A 3 year old female with history of cerebellar atrophy in a persistent vegetative state s/p ventriculoperitoneal shunt, chronic respiratory failure s/p tracheostomy placement and on home ventilator, G-tube dependent for nutrition, seizure disorder, steroid-induced pancreatitis complicated by PFC, was admitted with septic shock secondary to pneumonia. After initial improvement, she was found to have recurrent septic shock 3 weeks into her hospitalization due to infected PFC. Despite IV Meropenem and Fluconazole, she had persistent fevers in the setting of: negative blood and urine cultures, normal Chest X-Ray, and remained on her baseline ventilator settings. After attempted percutaneous drainage by Interventional Radiology, the decision was made to pursue endoscopic drainage. Endoscopic ultrasound-guided cystgastrostomy was completed on 4th week of admission using a LAMS. Subsequently, the patient's fevers resolved; however, the peripancreatic fluid collection persisted, requiring endoscopic pigtail catheter placement 14 days later. Unfortunately, the patient's sepsis worsened, and the patient's family decided to pursue comfort measures 12 days later. This is a rare case of a LAMS placed in a pediatric patient for drainage of a PFC. One of the challenges faced in the pediatric population is the limited equipment options and the size of the patient. LAMS have rarely been used in pediatric patients without adverse events directly related to stent placement. According to the literature, adult endoscopes and devices can be used safely in children>3 years of age or >15kg in weight. Consideration should be made on a case-by-case basis should LAMS placement be indicated in a young patient.2463_A Figure 1.
