Esophageal replacement with colon interposition in children
Insights
Colon interposition surgery offers excellent outcomes for children with esophageal atresia and benign strictures, with 84% achieving excellent results. This procedure is a safer alternative to esophageal elongation for complex cases.
Area of Science:
- Pediatric Surgery
- Thoracic Surgery
- Gastroenterology
Background:
- Colon interposition is a reconstructive surgical technique used for esophageal replacement.
- Indications include esophageal atresia and benign esophageal strictures in pediatric patients.
- Long-term outcomes and complication rates require thorough evaluation.
Purpose of the Study:
- To evaluate the long-term outcomes and complications of colon interposition in pediatric patients.
- To compare the outcomes of retrosternal versus left thoracic colon interposition.
- To assess the efficacy of colon interposition as an alternative to esophageal elongation for esophageal atresia.
Main Methods:
- Retrospective review of 39 colon interposition operations in 37 children over 21 years.
- Analysis of patient demographics, indications, surgical approach (retrosternal vs. left thoracic), and colon segment orientation (isoperistaltic vs. reverse).
- Assessment of postoperative complications, functional outcomes (weight gain, transit/emptying), and long-term results.
Main Results:
- Overall, 84% of patients had excellent results with a mean follow-up of 9.7 years.
- Common complications included anastomotic leak (12) and stricture (14).
- Isoperistaltic colon segments demonstrated better transit and emptying; retrosternal segments had less distension than left thoracic.
- 32 of 36 children increased their weight percentile post-operation.
Conclusions:
- Colon interposition is a safe and effective procedure for pediatric esophageal reconstruction, yielding excellent long-term results.
- Retrosternal isoperistaltic colon interposition appears to offer better functional outcomes.
- This technique is a viable and potentially safer alternative to prolonged esophageal elongation in complex esophageal atresia cases.
Abstract:
During a 21-year period, 39 colon interposition operations were performed on 37 children at the UCLA Medical Center and the Childrens Hospital of Los Angeles. The average age at the time of operation was 5.8 years. The indications for operation were esophageal atresia in 23 patients and other benign strictures in 14 patients. The duration of patient follow-up ranged from 6 months to 21 years (mean: 9.7 years). The most common complications were esophagocolonic anastomotic leak (12), esophagocolonic anastomotic stricture (14), pneumonia, and pneumothorax. Fourteen of the 25 patients with retrosternal colon interposition had complications (56%), whereas 10 of 14 patients with left thoracic colon interposition had complications (71%). One patient died (mortality: 3%) after left thoracic interposition because of severe respiratory distress associated with other malformations. Each of the 18 patients with isoperistaltic colon interposition showed rapid transit and emptying, provided that obstruction or extensive dilatation did not occur; reverse colon segments were more dilated and emptied more slowly. The 25 patients with retrosternal colon segments had less colonic distension with better emptying than did the 14 patients with left thoracic interposition. Thirty-two of the 36 children increased their weight percentile after colon interposition. Within 2 years after cervical anastomotic stricture or leak, 78% of these children were asymptomatic and gaining weight. Thirty-one of the 37 patients (84%) had excellent results with colon interposition, with a mean follow-up of 9.7 years. Most of the major postoperative complications occurred within the first few weeks and were corrected during the first few months after operation. Preservation of the esophagus should be the surgeon's first priority; however, prolonged attempts to elongate the esophagus for anastomosis in certain patients with long-gap esophageal atresia have been more hazardous in our experience than has colon interposition.
