Massive Septic Shock and Complex Survivorship in a Medically Complex Pediatric Patient Following Gastrostomy Tube Malposition With Operative Findings of Feed Within the Retrorectus Space

Gastrostomy tube (G-tube) replacement is often routine; however, in children with complex medical needs, misplacement can rapidly lead to life-threatening complications. We describe the case of a 16-year-old male patient with neuronal ceroid lipofuscinosis who developed fulminant septic shock after accidental G-tube dislodgement and malposition. At an outside hospital, reinsertion attempts required tract dilation; bloody aspirate and inconclusive radiographs were overlooked, and feeds were resumed at home. After 48 hours, the patient presented to a community hospital in profound shock (blood pressure 40/20 mmHg, lactate 7.8 mmol/L, procalcitonin >50 ng/mL) with extensive abdominal wall emphysema and feed extravasation into the scrotum. Despite maximal fluid resuscitation, he required norepinephrine, epinephrine, vasopressin, broad-spectrum antibiotics, intubation, and central line placement. Pediatric surgery at a tertiary center advised immediate source control prior to transfer; local surgeons performed emergent laparotomy, washout, and vacuum-assisted closure. Cultures grew Klebsiella pneumoniae, Enterococcus faecalis, and Bacillus cereus. His pediatric intensive care unit (PICU) course included necrotizing soft tissue infection of the abdominal wall, atrial fibrillation requiring cardioversion, repeated debridements, and two skin grafts. Discharged after 91 days, he required ongoing wound care and experienced multiple readmissions for pneumonia and septic episodes. This case illustrates how routine G-tube replacement can escalate into catastrophic sepsis in patients with complex medical needs. Early recognition, confirmatory imaging, prompt source control, and aggressive multidisciplinary care were lifesaving. Survivorship challenges, including repeated infections, wound care, and caregiver burden, underscore the importance of structured post-sepsis planning.
