Reply to Dr Bell

It is with deep respect that we write this response to Dr Bell1 who has inspired generations of physicians to do research on acquired neonatal intestinal diseases, most notably NEC. We are also pleased to read his agreement that spontaneous intestinal perforation (SIP) and necrotizing enterocolitis (NEC) are distinct and separate disease entities. We hope that this editorial exchange will encourage others to consider how best to approach these disparate diseases and the populations they affect.
