Indications for repeated enema reduction of intussusception in children
Insights
Delayed presentation significantly reduces the success of non-operative intussusception treatment. Early intervention with ultrasound-guided saline enema is crucial for successful reduction in children.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Emergency Medicine
Background:
- Intussusception is a frequent childhood abdominal emergency, often idiopathic.
- Nonoperative hydrostatic or air enema reduction is the primary treatment.
- Incidence ranges from 1.5-4 per 1,000 live births.
Purpose of the Study:
- To assess how clinical presentation and symptom duration impact non-operative intussusception treatment.
- To evaluate indications for and efficacy of delayed enema reduction.
Main Methods:
- 102 pediatric patients with ileocolic intussusception underwent ultrasound-guided saline enema.
- Symptom duration was analyzed as a predictor variable.
- Outcomes of initial treatment, delayed enemas, and surgery were reviewed.
Main Results:
- Successful enema reduction occurred in 57% of patients (58/102).
- Success rates were significantly higher with symptom duration < 24 hours (87%) versus > 24 hours (9%).
- Children with symptoms > 24 hours had a 91% risk of requiring surgery.
Conclusions:
- Ultrasound-guided saline enema is highly accurate for intussusception reduction.
- Delayed presentation markedly decreases non-operative treatment success.
- Delayed enema reduction is a viable option, but surgery is necessary for complications.
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 it 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.
