Abstract: Objective To explore the clinical and MDCT features of pediatric irreducible intussusception. Methods 66 patients were divided into irreducible intussusception group (19 cases) and reducible intussusception group (47 cases). Age clinical courses, length of intussusception body (L), neck max diameter (D1), head max diameter (D2) andthe ratio (D2/D1) and MDCT imaging data were compared and analyzed. Results (1) The course time, L and D2/D1 values of irreducible intussusception group were significantly higher than those of reducible group, the D1 was lower than that ofreducible group, and the difference is statistically significant (P<0.05). Clinical course,L and D2/D1 value AUC values were more than 0.7, the threshold values were 33.0 h, 7.5 cm and 1.33. (2) The occurrence rate of non-ileum-colon intussusception, Meckel's diverticulum, appendicitis and intestinal necrotic for irreducible intussusception were 36.8%, 21.1%, 21.1%, 15.8%and 10.5%respectively. Conclusion Whenthe time of course>33.0 mo, D2/D1>1.33 and L>7.5 cm, the irreducible intussusceptioncould be considered, and Meckel??s diverticulum, intestinal necrosis, appendicitis and intestinal obstruction should be judged further.
