Risk factors associated with failed sonographically guided saline hydrostatic intussusception reduction in children



Risk factors associated with failed sonographically guided saline hydrostatic intussusception reduction in children



Journal of Ultrasound in Medicine 33(9): 1669-1675



The aim of this study was to explore the risk factors associated with failed sonographically guided saline hydrostatic intussusception reduction in children. We retrospectively reviewed the medical records and sonograms of 288 cases of intussusception over a 3-year period. Logistic regression was used for the analysis of the clinical data (sex, age, duration of symptoms, and presence or absence of emesis or bloody stool) and sonographic features (initial location and intussusception length, presence or absence of free peritoneal fluid, and trapped fluid in the intussusception). The sex, age, and duration of symptoms showed no significant impact on the hydrostatic reducibility. The success rate became significantly lower for the intussusception cases with the presence of bloody stool, free peritoneal fluid, and trapped fluid in the intussusception (P < .05). The success rate was also lower when the intussusceptions were located in the left side of the abdomen (P < .05). For the above risk factors, the odds ratios from multivariate logistic regression analysis were 174.68 for initial intussusception location in the descending colon/rectum, 36.06 for the presence of peritoneal fluid, 13.22 for trapped fluid in the intussusception, and 9.27 for the presence of bloody stool. An initial intussusception location in the descending colon/rectum, the presence of peritoneal fluid, trapped fluid in the intussusception, and bloody stool are the most important risk factors for failure of sonographically guided saline hydrostatic intussusception reduction.
