ABSTRACT
This article presents the results of endoscopic treatment for recurrent postcorrosive esophageal stenosis with a tube-stent developed at our institution. The tube-stent was implanted in 5 children with corrosive esophageal injury at the age of 2 to 8.5 years after 7 to 64 dilatation sessions during 5 to 118 months. In total, 13 tube-stents were implanted. One patient had undergone 9 procedures during 2.5 years and the tube-stent remained in place for 14 to 250 days. This patient was tube-stent-dependent due to the lack of any possibility of surgical reconstruction. Two patients had the tube-stent removed after 150 to 205 days and they remain free from esophageal restenosis. One patient did not tolerate the tube-stent, evacuated it after 1 day and was referred for surgical esophagus replacement. One patient is currently still being treated with the tube-stent. Tube-stent was well tolerated and it may be effective in children with recurrent critical postcorrosive esophageal stenosis.

This report presents the case of an 8.5-year-old boy with Down syndrome after experiencing extensive caustic injury to the oesophagus and stomach resulting from the accidental ingestion of concentrated sulphuric acid. The patient had undergone 32 unsuccessful endoscopic oesophageal stricture dilatations and stenting procedures performed over a period of 15 mo following the accident. Surgical reconstruction of the oesophagus was not possible due to previous gastric and cardiac surgeries for congenital conditions. Before referring the patient for salivary fistula surgery, the patient received a nasogastric tube with perforations located above the upper margin of the oesophageal stenosis for the passage of saliva and fluid. The tube was well tolerated and improved swallowing; however the backflow of gastric contents caused recurrent infections of the respiratory tract. To overcome these problems, we developed a double lumen, varying diameter, perforated tube for protection of the oesophageal closure. This nasogastric tube was found to be safe and decreased the need for hospitalization and further endoscopic procedures. This newly developed tube can thus be considered as a treatment option for patients with recurrent oesophageal stenosis and contraindications for surgical oesophageal reconstruction.
