Ultrasound-guided Hydrostatic Reduction of Acute Intussusception in Children at a Tertiary Care Center: An Observational Study.

Introduction: Intussusception is common cause of acute emergency responsible for bowel obstruction in infants and toddlers with peak age of incidence between 6-9 months. Ultrasound is imaging modality of choice for diagnosis of intussusception and ultrasound guided hydrostatic enema reduction is standard, nonsurgical, internationally preferred treatment modality for uncomplicated pediatric intussusceptions. This study was aimed to find the outcome of the procedure.

Methods: An observational cross-section was carried in a tertiary care center in children presenting with intussusception. Ultrasoud guided hydrostatic reduction was done in all radiologically confirmed intussusception in children presenting to our tertiary hospital from February 2023 to July 2024 fulfilling the inclusion criteria after proper resuscitation. Patients having marked abdominal distension with features of peritonitis were excluded from the study. Ethical approval was obtained from Institutional Review Committee (Reference number: 287/2023).

Results: Total 81 patients with 84 intussusceptions underwent ultrasound guided hydrostatic reduction with male to female ratio of 2.86 and mean age 9.49±8.43 months. Hydrostatic reduction was successful in 78 (92.85%) cases. Among successful reductions, 3 (3.84%) patients had recurrence and repeat successful hydrostatic reduction was done. Presenting complain seen were abdominal pain 81 (100%) , vomiting 72 (88.89%). Ileocolic intussusception was seen in 74 (88.09%).

Conclusions: The success rate of ultrasound-guided hydrostatic reduction using normal saline for uncomplicated intussusception was consistent with findings from previous studies conducted in similar settings, which utilized both hydrostatic and pneumatic reduction methods.
