[Increasing frequency and diagnostic difficulties in intestinal stenosis after necrotizing enterocolitis].
BACKGROUND
Stenosis after necrotizing enterocolitis (NEC) has increased from 15 to 57% over the last 10 years in our unit. The aim of this study is to point out the difficulty of diagnosis and treatment, and search for factors explaining this increase.


METHODS
From 1986 to 1991, 42 newborns had NEC, followed by intestinal strictures in 19 of them (57% of the 33 survivors). Data from these 19 patients were compared with those of the 14 without intestinal strictures. The 33 survivors were also compared with those of an earlier study including 25 NEC seen from 1979 to 1986.


RESULTS
After medical treatment (n = 12), intestinal stenosis led to occlusion after three weeks, was located to both small and large intestine and was short and tight. After surgical treatment (n = 7), stenosis was shown by opacification before digestive anastomosis (n = 5) or revealed by occlusion (n = 2); it stayed on the colon, was long or multiple, requiring extensive resections. No difference could be found between data from patients with or without stenosis. Although newborns were actually more premature, the risk of stenosis was more frequent when newborns of same gestational ages and/or weights were compared.


CONCLUSIONS
Intestinal stenosis is a frequent complication after NEC; its diagnosis is often difficult and requires extensive digestive resections. No clinical or therapeutic factor could be found to explain the actual increase in frequency.
