Is it safe to discharge intussusception patients after successful hydrostatic reduction?
OBJECTIVE
The aim of this study was to evaluate whether discharge from the emergency department (ED) after successful hydrostatic reduction (HR) of intussusception is safe.


METHODS
We conducted a single institution review of patient records with a diagnosis code of intussusception from 1995 to 2006. Data collected included age, clinical presentation, imaging, surgical interventions, pathology, recurrence, and disposition. Statistical analysis utilized chi(2) tests, where P < or = .05 was considered significant.


RESULTS
A total of 309 patients with intussusception were identified. One hundred twenty-three patients (39.8%) required surgical intervention, 138 (44.6%) patients were managed nonoperatively as inpatients, and 48 (15.5%) were treated nonoperatively and discharged from the ED. There were 18 recurrences (5.8%). Recurrence rates did not significantly differ between patients who required operative reduction and those who were managed nonoperatively with HR and either observed as inpatients or discharged from the ED. Seven patients with recurrences required surgical intervention, and 1 of those children had a pathologic lead point, which was nonneoplastic.


CONCLUSIONS
Recurrence rates do not differ between children observed as inpatients and those discharged home after successful HR. Missed neoplastic pathologic lead points were not found in the patients who required an operation after a recurrence. Our data suggests that it is safe to discharge patients selectively from the ED after successful HR.
