Objective: to summarize the own experience of using ultrasonography (US) with Doppler sonography to determine the level and extent of bowel lesion and solve the issue of further surgical tactics in the treatment of newborns with necrotizing enterocolitis (NEC).
Material and methods. The work based on the results of the pro- and retrospective study analysis of 111 newborns’ examination with necrotizing enterocolitis. Among them, 79 (71.2%) newborns were operated and 32 (28.2%) received the conservative treatment. The diagnosis was determined based on the results of physical examination and instrumental (X-ray, US and Doppler sonography) methods. In 41 (66.1%) cases the stoma was formed after the resection, and in 21 (33.9%) cases the intervention was completed with the superimposition of primary anastomosis.
Results. The total mortality among newborns after surgical treatment made up 17.7% (11 infants), including 19.5% (8 newborns) with the stoma formation and 14.3% (3 children) with the initial anastomosis. The various postoperative complications were observed in 17 (41.5%) children with stoma formation and in 5 (23.8%) patients after initial anastomosis. The post-operative lethality was 22.8%.
Conclusions. The prognostic value of the results of clinical, laboratory and instrumental methods of examination relative to the severity of damage in necrotizing enterocolitis was determined. The significance of examination results in diagnosing the severity of disease was proved. The high informative value of determining the levels of inflammatory mediators and Doppler sonography as non-invasive diagnostic methods based on the results of the research was confirmed. The use of Doppler sonography before the surgery allows detecting circulatory disturbances in the intestinal wall before the occurrence of perforation allowing to perform surgery at the most optimal time as well as to prevent peritonitis. It has been proposed to include drugs with anti-cytokine properties (pentoxifylline) in the complex of conservative therapy; it will allow reducing the negative influence of mediators of the inflammatory response and, consequently, improving the clinical course of disease. The use of intraoperative Doppler sonography will allow to clearly defining the boundaries of healthy and damaged intestine; it will enable to apply primary anastomosis as well as to preventive intestinal stoma.
Key words: necrotizing enterocolitis, neonates, ultrasonography, inflammatory mediators, surgical treatment, primary anastomosis.
