Can a gut fatty acid given before surgery stop bowel problems in Hirschsprung's babies?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

The inclusion criteria are: * Newborn with a diagnosis of Hirschsprung's disease the 2 first months of life managed successfully with colonic decompressions/irrigations before curative surgery (usually performed 1-3 times a day) * Born at or after 35 weeks of gestation (37 weeks of amenorrhea) * With a short-segment Hirschsprung's disease limited to the rectum and/or sigmoid colon diagnosed on rectal biopsy with established pathological criteria (absence of ganglionic cells +/- hypertrophic extrinsic nerve fibres) (Kapur, 2009) * Uncomplicated form (without enterocolitis as defined by the HAEC score and/or diverting colostomy) * Curative surgery and follow-up in one of the included centres * With consent of the 2 parents or legal(s) representative(s) * Absence of severe or lethal associated malformations * Affiliation with the French social security system The non-inclusion criteria are: * Long segment Hirschsprung's disease prior to the junction between the left colon and the sigmoid colon * Hirschsprung's disease not managed successfully with colonic decompressions/irrigations and requiring a diverting colostomy before the curative surgery * Hirschsprung-associated enterocolitis occurring before the randomization (as defined by the HAEC score) * Severe or lethal associated malformation, including Down syndrome * Intestinal associated malformations (intestinal atresia, gastroschisis, omphalocele, intestinal malrotation and volvulus) * Any pathological condition that can modify intestinal motility or intestinal transit time (cystic fibrosis, hypothyroidism) * Refusal of parent(s) or legal representative(s) * Neonates under tutorship or guardianship Minors cannot be excluded because they are the population to be studied. The non-inclusion criteria are: * Long segment Hirschsprung's disease prior to the junction between the left colon and the sigmoid colon * Hirschsprung's disease not managed successfully with colonic decompressions/irrigations and requiring a diverting colostomy before the curative surgery * Hirschsprung-associated enterocolitis occurring before the randomization (as defined by the HAEC score) * Severe or lethal associated malformation, including Down syndrome * Intestinal associated malformations (intestinal atresia, gastroschisis, omphalocele, intestinal malrotation and volvulus) * Any pathological condition that can modify intestinal motility or intestinal transit time (cystic fibrosis, hypothyroidism) * Refusal of parent(s) or legal representative(s) * Neonates under tutorship or guardianship Minors cannot be excluded because they are the population to be studied. The non-inclusion criteria are: * Long segment Hirschsprung's disease prior to the junction between the left colon and the sigmoid colon * Hirschsprung's disease not managed successfully with colonic decompressions/irrigations and requiring a diverting colostomy before the curative surgery * Hirschsprung-associated enterocolitis occurring before the randomization (as defined by the HAEC score) * Severe or lethal associated malformation, including Down syndrome * Intestinal associated malformations (intestinal atresia, gastroschisis, omphalocele, intestinal malrotation and volvulus). * Any pathological condition that can modify intestinal motility or intestinal transit time (cystic fibrosis, hypothyroidism) * Refusal of parent(s) or legal representative(s) * Neonates under tutorship or guardianship Minors cannot be excluded because they are the population to be studied.
