Non-operative reduction has emerged as rst line in the management of uncomplicated intussusception. The aim of this study was to compare the outcome of saline hydrostatic reduction and pneumatic reduction of intussusception in infants.
MethodsThis is a prospective study of infants with uncomplicated intussusception con rmed by ultrasound over a period of twenty-one months from December, 2018 to August, 2020. Fifty-two (69.3%) out of seventyve infants underwent enema reduction under ultrasound guidance. The success rates, time to reduction and complication rates were assessed.
ResultsThe success rates, between the saline hydrostatic reduction group and pneumatic reduction group, were comparable [17(65.4%) versus 19(73.1%); relative risk (RR) 0.8; 95% con dence interval (CI) 0.6-1.2; p = 0.54]. The mean time to reduction was higher in the saline hydrostatic reduction group (15.4 ± 5.1 minutes versus 10.8 ± 4.1 minutes; p = 0.003). The two groups had similar complication rates; for perforation [1(3.8%) versus 0(0.0%); RR 0.9 (CI 0.9-1.0); p = 0.31] and recurrence [2(7.7%) versus 1(3.8%); RR 0.9 (CI 0.8-1.0); p = 0.55].
ConclusionSaline hydrostatic reduction and pneumatic reduction of uncomplicated intussusception under ultrasound guidance in infants might have comparable outcomes. However, pneumatic reduction may be faster.
