Insights
Conservative treatment is effective for pediatric adhesive small bowel obstruction (ASBO). This approach, involving nasogastric decompression and fluid correction, shows success rates from 16% to 75% and reduces hospital stays compared to surgery.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Clinical Effectiveness Research
Background:
- Adhesive small bowel obstruction (ASBO) is a common surgical complication in children.
- Conservative management is often the initial approach for pediatric ASBO.
Purpose of the Study:
- To evaluate the effectiveness of conservative (non-operative) treatment for ASBO in pediatric patients.
- To compare outcomes of conservative management with surgical intervention.
Main Methods:
- Systematic review of 7 studies (6 retrospective, 1 prospective) involving children with ASBO.
- Included patients received conservative treatment: nasogastric decompression, parenteral fluids, and electrolyte correction.
- Primary outcome was treatment success; secondary outcomes included hospital stay and time to first feeding.
Main Results:
- Conservative treatment success rates varied from 16% to 75% across studies.
- Hospital length of stay was significantly shorter with conservative treatment (3-6.5 days) compared to operative treatment (10.2-13 days).
- Time to first feeding was also reduced with conservative management (31-84 hours).
Conclusions:
- Conservative treatment is an effective initial management strategy for the majority of pediatric ASBO cases.
- Non-operative management offers benefits in terms of reduced hospital stay and earlier oral feeding.
- Further research may refine patient selection for conservative versus operative approaches.
Objective:
To assess the effectiveness of conservative treatment for adhesive small bowel obstruction (ASBO) in children.
Design:
Systematic review of studies involved children with ASBO who received initial conservative/non-operative treatment.
Setting:
The search was performed in April 2013 using PubMed (see online supplementary file 1), current contents, and the Cochrane database.
Participants:
Children with ASBO.
Interventions:
Conservative treatment included nasogastric decompression, parenteral fluids and correction of electrolyte and fluid imbalance.
Primary Outcome:
Treatment success.
Secondary Outcomes:
Length of hospital stay and the time to first feeding after hospital admission.
Results:
7 studies (six retrospective, one prospective), involving 8-109 patients (age: 1 month to 16 years) treated conservatively, were included in the review. The nature of conservative treatment was generally consistent between studies (nasogastric decompression, parenteral fluids and correction of electrolyte and fluid imbalance), although patients in one study also received Gastrografin. The rate of conservative treatment success ranged from 16% to 75% among the five studies, but one trial showed 0% successful rate. The hospital length of stay ranged from 3 to 6.5 days for conservative treatment (vs 10.2-13 days for operative treatment). The time to first feeding ranged from 31 to 84 h for conservative treatment.
Conclusions:
In conclusion, in the majority of cases, conservative treatment is an effective means of managing ASBO in children.
