Growth and fat absorption after resection of ileum in childhood
Insights
Children surviving extensive ileum resection can often tolerate normal diets and grow well within two years, despite absorption issues. Some infants may need prolonged nutritional support after major ileum resections.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Nutritional Science
Background:
- Extensive ileum resection in children presents challenges in long-term nutritional management and growth.
- Understanding the adaptive capacity of the remaining gastrointestinal tract is crucial for post-surgical care.
Purpose of the Study:
- To assess the long-term outcomes of children who underwent extensive ileum resection.
- To evaluate diet tolerance, growth, and absorption defects in pediatric patients after significant ileum resection.
Main Methods:
- Longitudinal reassessment of twelve children (neonatal and childhood resections) over 3 to 16 years.
- Monitoring for persistent diarrhea, dietary restrictions, growth parameters (weight-for-height, height percentiles), and steatorrhea.
- Assessing serum vitamin levels (A, D, E).
Main Results:
- No persistent diarrhea beyond one year post-resection in any child.
- Only two children required fat-restricted diets for over two years, with no growth advantage observed compared to those on normal diets.
- Children's weights were appropriate for heights; heights were generally comparable to siblings, with only two below the third percentile.
- Marked steatorrhea persisted in older children, but serum vitamin levels remained normal.
- Two years post-resection, many children tolerated normal diets and exhibited good growth despite residual absorption defects.
Conclusions:
- Children can achieve adequate growth and tolerate normal diets within two years after extensive ileum resection, even with ongoing absorption issues.
- While some children adapt well, infants with more extensive resections may require extended special diets and vitamin supplementation.
- The ileum demonstrates significant adaptive capacity, allowing for improved outcomes in pediatric surgical patients with massive resection.
Abstract:
Twelve children who have survived resection of more than 45 cm of ileum (eight during the neonatal period and four later in childhood) have been reassessed at periods ranging from 3 to 16 years. No child had persistent diarrhea for longer than one year after a resection, and only two children had a restricted fat intake for more than two years. These two children showed no advantage in growth compared with the ten who had normal diet within two years of the resection. The weights of individual children are appropriate for their heights. Their heights tend to be less than those of their siblings, but only two are less than the third percentile compared to height expected in relation to that of parents. The older children still have marked steatorrhea but no diarrhea, and serum levels of vitamins A, D, and E are normal. These observations suggest that two years after extensive resection ileum some children may tolerate a normal diet and grow well despite persisting defects in absorption. Infants with more extensive resections are now surviving and may require special diets and vitamin supplements for longer periods of time.
