Preterm Birth Clinical Trial
— NECO2Official title:
Study of the Influence of Intraperitoneal Insufflation of Carbon Dioxide (CO2) by Laparoscopy on the Short-term Evolution of Premature Infants With Ulcerative Necrotizing Enterocolitis
Ulcerative-necrotizing enterocolitis (ECUN) is an infectious and inflammatory disease of the digestive tract, which can lead to intestinal necrosis or perforation. This severe pathology of the newborn , often premature, requires urgent medical and surgical treatment in 25 to 50% of cases. The morbidity is high, both digestive and neurological. ECUN can lead to complications at short-term (death, intestinal stenosis) and at long-term (neuro-cognitive disorders). The challenge of preserving the neurological development is a major issue. It involves control of inflammation. This inflammation causes neurological lesions and is responsible for a disorder of the long-term neurocognitive development. At Robert-Debré and Trousseau, the management of newborns with ECUN is focused on the control of this inflammation. A laparoscopy is performed first. The carbon dioxide (CO2) insufflated into the abdomen during a laparoscopy is thought to have an anti-inflammatory effect according to several experimental and clinical studies. A preliminary retrospective study at Robert-Debré showed a decrease in postoperative inflammation (decrease in C reactive protein at Day2 and Day 7 post-op) as well as a decrease in morbimortality (decrease in the rate of stoma and reoperation) in children who had a laparoscopic first operation compared to those who had a laparotomy alone. However, in many hospitals, laparotomy alone is currently the only surgical option. This preliminary study may demonstrate that laparoscopy decreases early morbidity and mortality in children with ECUN through reduced inflammation, as reflected by postoperative C reactive protein.
