It is important to consider lipoblastoma in the diagnosis of a rapidly enlarging fatty mass in children. Complete resection is the only definitive treatment and should not be delayed when impingement on surrounding structures is imminent. There is a tendency for these lesions to recur despite presumed complete excision. Therefore, follow-up for a minimum of 5 years is recommended.

Background and Objectives: Purpose There are various causes and associated conditions in anomalous bands. Idiopathic congenital anomalous bands are extremely rare. The use of the term “congenital bands” may, in reality, not describe the same situation. The study aims to report our series of idiopathic anomalous bands and proposes an accurate and consistent classification of anomalous bands in order to clarify the origin of each band. Methods This study, conducted from January 2005 to January 2018, included all patients admitted to the emergency departments with a clinical diagnosis of intestinal obstruction resulting from bands that have no identifiable embryological or acquired basis called “idiopathic”. Recorded operative findings included the site of obstruction and the operative procedure to relieve it. Results The sample consists of seven boys and three girls with age range from one day to 9 years with symptoms and signs indicative of intestinal obstruction. Surgical intervention was performed, and intraoperative findings revealed a thick and vascularized idiopathic band, in different locations, which was responsible for intestinal obstruction in all patients. Clinical courses were uneventful in eight cases. Conclusion Idiopathic anomalous congenital bands causing intestinal obstruction are not frequently encountered in surgical practice and these bands are often difficult to classify and define. We believe that our new classification is a practical communication tool for medical professionals to summarize and clarify the different types of anomalous bands.
