EFFICIENCY OF THE ULTRASOUND (US) IN DETECTION OF INTUSSUSCEPTION AND ITS US- GUIDED SALINE REDUCTION

Background and Objectives: Intussusceptions is a major cause of intestinal obstruction in infancy and childhood. The increased use of ultrasound (US) in its diagnosis and reduction with normal saline has resulted in better outcome in patients. Materials and Methods: In this prospective study we evaluated the efficacy of ultrasound in diagnosis and treatment of intussusceptions in 21 children referred to Tabriz Childrenʹs Medical Center from 21st June 1996 until 21^ June 1997. Results: When ultrasound was performed on 21 patients for diagnosis of intussusceptions, 19 of these patients showed typical ftindings. Male to female ratio was 1.8 to 1. On ultrasound, none of the cases were detected as false negatives, however three false positives were noticed giving a sensitivity of 100%and specificity of 40%. When real-time ultrasound guided saline enema was performed in 17 patients, enema reduction was successful in 16 cases thus, achieving approximately an overall success rate. Contraindications for US- guided enema reduction were: bowel wall thickness greater than II mm, perforation, peritonitis and recurrent intussusceptions more than three episodes. Conclusion: Absence of radiation exposure, easy observation of the patientʹs condition during the procedure as well as high success rate of US- guided saline enema makes ultrasound detection, one of the most promising methods for nonoperative treatment of intussusceptions. In this procedure there is no need for surgery and anesthesia, thus it reduces surgical risks and even hospitalization cost too.
