Brief Summary
The goal of this observational study is to determine the normal development of the human intestinal immune system in premature and mature neonatal life and to determine the pathophysiology behind life-threatening gastrointestinal diseases that appear during early life. The main questions aim to answer are: * to determine the normal development of the human intestinal immune system in premature and mature neonatal life and to determine the pathophysiology behind life-threatening gastrointestinal diseases that appear during early life. * is to investigate the development of the immune system in relation to enteral nutrition during the neonatal period. Participants will be asked to give faecal samples from day 1 of life and weekly for the following weeks until discharge (preterm infants). Further, surgery faecal samples and intestinal tissue will be collected proximal and distal to the pathology. In cases with a stoma, and when the child will undergo later reversal surgery, tissue samples from the proximal and distal ends of the intestine will be collected together with fecal samples (preterm and children up to 1 year of age who need to undergo intestinal surgery due to atresia).
Eligibility Criteria
Inclusion Criteria: NEC study * Premature infants born \< GA week 32 Atresia study * All newborn and children up to 1 year of age who needs to undergo intestinal surgery due to atresia at any site of the intestine. Exclusion Criteria: NEC study - Premature born with congenital diseases or other serious conditions which may defer participation. Situations where collection of tissue at surgery is impossible or problematic e.g. due to remaining length of vital intestine is evaluated to be too short according to the discretion of the operating surgeon. Atresia study -Infants and children where intestinal tissue sampling would compromise surgery and the health of the patient subsequent.
