Congenital stenosis and atresia of the jejunum and ileum
Insights
Neonatal intestinal stenosis and atresia may stem from gut ischemia, potentially linked to pregnancy complications. This study examines 12 cases, suggesting a connection between fetal distress and these serious conditions.
Area of Science:
- Gastroenterology
- Neonatal Surgery
- Perinatal Medicine
Background:
- Intestinal stenosis and atresia are congenital anomalies affecting newborns.
- Gut infarction is a known complication in the neonatal period.
- Previous studies suggest associations between pregnancy complications and neonatal gut issues.
Purpose of the Study:
- To investigate the macroscopic and microscopic findings in 12 cases of jejunal and ileal stenosis and/or atresia.
- To explore potential etiological links between associated lesions, fetal distress, and intestinal atresia/stenosis.
- To review perinatal deaths for evidence of gut ischemia and its potential role in these conditions.
Main Methods:
- Presentation of macroscopic and microscopic findings in 12 cases of jejunal and ileal stenosis/atresia.
- Analysis of associated lesions in necropsy cases to identify signs of shock, intrapartum asphyxia, and intrauterine growth retardation.
- Review of perinatal death autopsies to assess the prevalence of gut ischemia.
Main Results:
- A uniformity was observed among cases of atresia, stenosis, and gut infarction.
- Nine out of 12 infants showed evidence of intrapartum asphyxia; eight had intrauterine growth retardation.
- Gut ischemia was found in 19 out of 56 reviewed perinatal deaths.
Conclusions:
- Associated pregnancy complications may play a significant role in the etiology of neonatal intestinal stenosis and atresia.
- Stenosis and atresia are suggested to be sequelae of prior gut ischemia.
- Fetal distress, including shock and asphyxia, appears linked to these intestinal anomalies.
Abstract:
The macroscopic and microscopic findings in 12 cases of stenosis and/or atresia of the jejunum and ileum are presented. There was considerable uniformity within the series with overlapping of cases of atresia, stenosis, and gut infarction. An analysis of associated lesions in cases coming to necropsy suggests that the infants were suffering from shock. In nine out of the 12 cases there was evidence of intrapartum asphyxia and in eight cases evidence of retardation of intrauterine growth. It is argued that, since many of the associated complications of pregnancy are known to be of importance in the aetiology of gut infarction in the neonatal period, they are likely to be of aetiological significance in the development of atresia and stenosis of the gut. A review of perinatal deaths shows that gut ischaemia of varying degrees of severity is a common finding at necropsy, being noted in 19 out of 56 cases studied. It is suggested that stenosis and atresia are sequelae of previous gut ischaemia.
