Objective: In this study, we describe the management and outcome of children with intussusception and analyze the sonographic findings that can be used to differentiate transient, self-limited small bowel intussusception from the cases with an indication for surgery. Material and Methods: We retrospectively reviewed the medical records of pediatric patients with the diagnosis of invagination who had been followed up in the pediatric surgery service between 2012-2017. Results: The median age was 39.5±35.9 (range 2-171) months. Among these patients, 57 (64%) had been followed up without surgery, and the remaining patients (n= 32, 36%) had undergone surgery. The median age of patients who had not undergone surgery was significantly greater than that of the patients who had undergone surgery (52.2±38.4 vs. 16.75±12.6; p<0.001). Twenty (35.1%) patients in the non-surgical group had developed abdominal pain after discharge, whereas none of the patients in the surgical group had developed abdominal pain postoperatively. An analysis of the differences between the groups with respect to the length of the invaginated segment revealed that length of that segment were significantly greater in the surgically managed cases (p=<0.001). A ROC curve based on the length of the invaginated intestinal segment revealed that, 41.5 mm was the best cutoff point for invaginated intestinal length, which resulted in a sensitivity of 68.8% and a specificity of 96.5%. Conclusion: In our study, unlike other studies, the surgical threshold of the invagination length was revised as 4.15 cm. Thus, patients below this value may not have an immediate indication for surgery.
