The Role of a Mesadenitis in Formation of the Intussusception in Children: Results of Retrospective Study

Abstract

The intussusception (IS) often is followed mesadenitis, however a question, whether it is the reason or a consequence of formation of the intussusception, remains disputable. Aim: To estimate a role of the mesadenitis in formation of the intussusception in children. Methods: Retrospective study of results of treatment of all treated children with intussusception (n = 270) in the Arkhangelsk regional children's hospital in 1981-2012 is executed. Estimated the frequency of the background infectious and inflammatory diseases capable to be the cause for the mesadenitis. Studied the frequency of identification and the sizes of lymph nodes (LN) in structure of the intussusception according to ultrasonography and hydrocolonic sonography (HS) depending on duration of symptoms of IS. Results: It was verified that symptoms of diseases which are followed mesadenitis initially met in 66 % of patients. Thus according to ultrasonography in structure of intussusceptum LN in 82 % of patients were defined. It wasn't revealed statistically significant interrelation between time from the moment of the beginning of an IS, length of the LN (x2(2) = 0,11; р = 0,948) and cross size (x2(2) = 0,05; р = 0,975). The largest LN was localized in the head of the intussusceptum. Reduction by method of HS allowed to visualize LN in structure of the intussusceptum, its efficiency made 95,6-100 %. Conclusion: Mesadenitis is the most frequent reason of the intussusception in small children. The understanding of the role of mesadenitis in formation of the IS promotes more effective conservative treatment.
