The Prevalence of Mesenteric Adenitis among Children with Intussusception: A Cross-sectional Study

Background & Objective: Intussusception is the most common abdominal emergency in children.The present study was designed to investigate the prevalence of mesenteric adenitis among children with intussusception. Materials & Methods:This cross-sectional study was conducted on 81 children aged 4 to 48 months with intussusception who were referred to Mousavi Zanjan Hospital during 2019-2021.Data were collected using a checklist including demographic and clinical variables extracted from the patients' records.The data were analyzed using SPSS software, version 26. Results:The meanSD age of the participants was 22.3013.56months.Most children were girls (70.4%).Ileocolic (45.8%) was the most common type of intussusception, and most children had mesenteric adenitis (79%).In terms of number, most (93.7%)cases of adenitis were multiple, and the right lower quadrant (RLQ) was the most common site of adenitis (85.9%).Moreover, 56.2% of adenitis had a diameter of less than 1 cm.No statistically significant associations were observed between mesenteric adenitis and variables such as age, sex, weight, time of onset of symptoms, duration of hospitalization, vomiting, type of intussusception, type of nutrition, type of treatment, and type of delivery (P>0.05).However, there was a statistically significant relationship between jelly stool and mesenteric adenitis, so all children with jelly stool had mesenteric adenitis (P=0.009). Conclusion:The prevalence of mesenteric adenitis was high in children with intussusception, and a significant association was observed between these two diseases.However, further studies with larger samples are recommended.
