After caustic ingestion, patients may be either asymptomatic or may exhibit a variety of initial signs and symptoms, depending on the digestive segment predominantly affected. The DROOL system is a noninvasive scoring method used for the evaluation of esophageal lesions and has a good correlation with the development of esophageal stenosis. Management of these patients depends on several factors, including the presence of the symptomatology, in addition to the nature of the caustic substance. Upper endoscopy is indicated in the first 48 hours or after the first two weeks, when it is recommended to start endoscopic dilation sessions. If endoscopic treatment is inefficient, surgical treatment is required.

Abstract
Background A major limitation of current treatment strategies for nonmalignant upper gastrointestinal stenoses is the lack of either optical or haptic feedback during dilation. Wire guidance and fluoroscopy is often necessary to control the position.
Methods A novel device for endoscopic dilation, the BougieCap (Ovesco Endoscopy AG, Tübingen, Germany) was evaluated in a prospective multicenter trial. Primary outcome was successful dilation of stenosis and secondary outcome was alteration in dysphagia symptoms in short-term follow-up.
Results 50 patients with benign esophageal strictures were included. Endoscopic bougienage was successful in 96 %. Bougienage failed in two cases because of high resistance. Symptoms of dysphagia decreased significantly after bougienage (59.0 points at Day 0 vs. 28.6 points at Day 14; P < 0.001). Adverse events were loss of BougieCap into the stomach in two cases; no severe adverse events were reported.
Conclusions Endoscopic treatment of benign stenoses using the BougieCap enabled direct visual control of the bougienage procedure. This might help to adapt treatment more precisely to the stricture. Symptoms of dysphagia were improved in short-term follow-up. Additional wire guidance may be used for selected cases (e. g. narrow lumen, pediatric scope).
Congenital anomalies that can produce esophageal stenosis as well as acquired diseases of the esophagus in children are described. The infant and child who refuse to accept solid foods must be submitted to roentgenologic and endoscopic examination. Dysphagia is sometimes difficult to recognize in infants and children. Endoscopic treatment alone or associated with surgery is successful in many cases if well indicated and precisely done.
