Functional and metabolic evaluation of colon replacement of the esophagus in children
Insights
Colon interposition surgery for esophageal replacement in children showed good functional outcomes. However, some patients experienced delayed growth, anemia, and vitamin B12 malabsorption, linked to the length of the ileum used.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Nutritional Science
Background:
- Esophageal replacement using colon interposition is a surgical technique for pediatric esophageal conditions.
- Long-term outcomes and potential complications require thorough evaluation.
Purpose of the Study:
- To assess the functional and metabolic outcomes in children who underwent colon interposition for esophageal replacement.
- To identify factors influencing growth, nutrient absorption, and gastrointestinal transit.
Main Methods:
- Retrospective follow-up of 13 children (1962-1976) who had colon interposition.
- Detailed functional and metabolic evaluation in 8 patients.
- Radiologic and manometric assessments of the interposed segments.
Main Results:
- Good functional results were generally observed.
- Delayed growth was noted in patients with esophageal atresia, particularly those with congenital anomalies.
- Four patients developed anemia with low iron levels; three had abnormal vitamin B12 absorption correlated with ileal segment length.
- Manometry showed absent peristalsis in colon segments but present in ileal segments.
- Radiology indicated delayed transit of thick materials and variable overall intestinal transit time.
Conclusions:
- Colon interposition offers acceptable functional results for esophageal replacement in children.
- Potential complications include growth delay, anemia, and vitamin B12 malabsorption, necessitating monitoring.
- The length of the interposed ileum may impact vitamin B12 absorption.
Abstract:
Thirteen children with esophageal replacement with colon interposition have been followed at the University of Florida Medical Center between 1962 and 1976. Eight of these patients were evaluated with a detailed functional and metabolic protocol, four requiring colon interposition for esophageal atresia and four for esophageal strictures. Growth was noted to be somewhat delayed in the patients with esophageal atresia, especially those with associated congenital anomalies. Otherwise, excellent functional results were obtained. Significant anemia with depressed serum iron concentrations was noted in four patients, and three patients had abnormal vitamin B12 absorption. This abnormality correlated with length of terminal ileum employed with the interposed segment. Serum parameters of intestinal absorption were normal in each patient. Manometric evaluation revealed absence of peristalsis within the colonic segment, but progressive peristalsis within interposed ileal segments. Radiologic evaluation demonstrated delay in passage of thick material from mouth to stomach and wide variability in overall intestinal transit time.
