Background/Purpose: Several techniques have been used for esophageal replacement after corrosive esophageal injuries. 
The colon and stomach are the most commonly used conduit for esophageal substitution. This study was undertaken to 
compare the results of gastric pull-up versus colon interposition in treatment of children with post corrosive esophageal 
stricture. 
Patients and Methods: Thirty patients (21 males and 9 females) with post-corrosive esophageal stricture were treated at 
Tanta University Hospital during the period from March 1993 to March 2003. Their ages ranged from 1.7 to 6 years (mean, 2.8 years). Seventeen patients (group I) were treated by transhiatal esophagectomy and gastric pull-up, while colon interposition after transhiatal esophagectomy was performed in 13 patients (group II). Patients were followed for a period of 3 months to 10 years. 
Results: The operative time ranged from 2-2.5 hours in Group I versus 2.75-3.5 hours in Group II. The most frequent 
complications were pneumothorax (n=5) in Group I, and external fistula (n=4) in Group II. There were 3 deaths (6.7%), one patient in Group I, and 2 in Group II. 
Conclusion: Both gastric pull-up as well as colon interposition are feasible and applicable in treatment of children with post corrosive esophageal stricture. However, gastric pull-up is more preferable in our unit, because the technique is more simple and easier to perform; it requires only one anastomosis, with less morbidity and mortality; and less operative time.
