Successful Mesenchymal Stem Cell Application in Supraventricular Tachycardia-Related Necrotizing Enterocolitis: A Case Report.

Necrotizing enterocolitis (NEC) is one of the most important life- threatening diseases in neonates. Recurrent episodes of supraventricular tachycardia (SVT) can lead to gut ischemia, with subsequent reperfusion injury resulting in NEC. Mesenchymal stem cells (MSCs) are multi-potential cells which can differentiate into multiple cell types. A 22-day old male baby delivered to 34 yr old mother at 37-weeks' gestation via cesarean section, birth weight 3550 g, developed NEC 14 hours after being treated with cardioversion for SVT. At laparotomy, there was pan-NEC, and 60 cm of necrotic and perforated bowel was resected. 1 × 10 umbilical cord origin allogeneic MSCs were given intravenously, with subsequent improvement of the remaining bowel. MSC may be a promising treatment for adjacent ischemic bowel in NEC helping prevent short bowel syndrome.
