Transhiatal esophagectomy and colonic interposition for caustic esophageal stricture.

From January 1986 through 1990, 70 children (42 boys, 28 girls) with esophageal stricture resulting from ingestion of caustic potash underwent simultaneous esophagectomy and colonic interposition utilizing the transhiatal esophageal approach. At the time of the procedure, their ages ranged from 14 months to 6 years (mean, 3.2 years). Thoracotomy was needed in one patient due to accidental injury to the tracheal during esophageal mobilization. There were 3 deaths from respiratory failure. Otherwise, morbidity was low, and there were satisfactory long-term functional results. The use of isoperistaltic left colon based on both ascending and descending branches of the left colic vessels resulted in survival of all grafts. End-to-side esophagocolic anastomosis decreased the incidence of both postoperative leak (2 instances) and late stenosis (1 case needed surgical revision). Construction of a length of colonic graft equal to the gap between the esophagus above the stricture and the stomach and fixation of the graft to the edge of the esophageal hiatus reduced the incidence of late colonic redundancy in the chest; this did occur in 4 cases but was not associated with dysphagia. Routine pyloroplasty and anterior cologastric anastomosis to the gastric antrum contributed to the absence of gastrocolic reflux and peptic ulceration in this series.
