Abstract Objective: To investigate the feasibility of ultrasound-guided warm saline enema therapy in infants with acute intussusception. Methods: The clinical data of patients with infant acute intussusception from Jan. 2010 to Dec. 2014 were collected and analyzed retrospectively． Patients were divided into operation and warm saline enema groups． Results: There were 92 cases of infant acute intussusception(50 males and 42 females, age ranging from 3 months to 8 years), 61 patients were cured with warm saline enema and 31 patients underwent surgery. The mean length, diameter and thickness of the intussusception were 3.54 cm, 1.78 cm and 0.36 cm respectively in the warm saline enema group, and 6.48 cm, 2.85 cm and 0.78 cm respectively in the operation group(P<0.001)． Multivariate regression analysis indicated that the “sleeve sign” length, “target ring sign” diameter and “sheath” thickness were independent influencing factors for the success of warm saline enema． ROC curve analysis indicated that the “sleeve sign” length≥4.5 cm, “target ring sign” diameter≥2.5 cm and “sheath” thickness≥0.5 cm of intussusception were optimal cutoff values to predict the need for surgery. Conclusion: The “sleeve sign” length<4.5 cm, “target ring sign” diameter<2.5 cm, and “sheath” thickness<0.5 cm predict the need for warm saline enema in pediatric patients with infant acute intussusception．
