Gastric tubes in children with caustic esophageal injury: a 32-year review.
OBJECTIVE
Caustic injury to the upper aerodigestive system with scarring of the pharynx, hypopharynx, and esophagus is a challenging reconstructive problem. The author has used the gastric tube for this purpose for three decades.


METHODS
During the last 32 years (1965 to 1996 inclusive) the author treated 11 patients who required esophageal replacement with a gastric tube conduit, which was anastomosed to the cervical esophagus. At the time of injury, ages ranged from 2 months to 13 years (mean, 3 years) in seven boys and four girls. Time from injury to esophageal replacement was 12 months to 14 years (mean, 5 years). All 11 had multiple dilations before the replacement. Two had injury and scarring of the epiglottis and larynx that required pharyngeal reconstruction and tracheostomy before replacement. Nine patients underwent reconstruction with a gastric tube anastomosed to the cervical esophagus, and the other two had an interposition with an intrathoracic anastomosis. Eight tubes were antiperistaltic and three isoperistaltic. Seven tubes were placed in the retrosternal space, three were transthoracic, and one was subcutaneous. Six tubes were completed in two stages and five in a single stage.


RESULTS
Nontube complications were wound infection (n = 2), perforation (n = 2), paralyzed hemidiaphragm (n = 1), and recurrent laryngeal nerve injury requiring tracheostomy (n = 1). Tube complications were anastomotic leak (n = 9), stricture (n = 8), anastomotic resection (n = 3), ulcer (n = 1), and perforation (n = 1). Six required posttube multiple dilations for several years including self-bouginage (n = 2). All learned to swallow and eat initially with minimal aspiration; only one remains on tube feed supplements. Long-term follow-up (3 to 30 years) includes nine eating normally and not requiring dilations (the tracheostomy boy has chronic lung disease), one lost to follow-up after 1 year, and one death from tube hemorrhage 2 months after operation.


CONCLUSIONS
Children with caustic injury to the upper aerodigestive system can undergo gastric tube replacement with good results. The majority of the problems relate to the esophagogastric tube anastomosis.
