Introduction. Intussusception is a common abdominal emergency in early
childhood. It is idiopathic in more than 90% of cases with incidence of 1.5-4
per 1,000 live births. The treatment of choice is nonoperative hydrostatic or
air enema reduction. Objective. The aim of the study was to evaluate the
influence of clinical presentation and symptom duration in non-operative
treatment, considering the indications for delayed enema reduction and its
efficacy. Methods. From the total number of 107 patients with
intusussception, aged from 2 months to 14 years (median 9 months), 102 (95%)
patients with ileo-colic intussusceptions were treated initially by
ultrasound guided saline enema. Records were reviewed for patients with
failed initial treatment and delayed repeated enemas or operative procedure.
The predictor variable included duration of presenting symptoms. Results.
Successful treatment by hydrostatic saline enemas had 58/102 (57%) patients.
Success in reduction was greater if symptom duration was <24 hours (54/62
cases; 87%, p<0.001), compared with >24 hours, (4/45 cases; 9%). Despite
failed initial attempts, enema reduction was reattempted in 12 patients, with
success in 7/12 (60%) patients. Children with symptom duration >24 hours had
a greater risk of requiring surgery (41/45 cases; 91%, p<0.001), including 5
(5%) patients with ileo-ileal intussusceptions. Conclusion. The accuracy of
ultrasound guided saline enema in intussusception reduction is high. Delay in
presentation decreases success of non-operative treatment. Delayed enema
reduction is important therapeutic option for intussusceptions. Surgical
treatment is indicated in cases of complications.
