Esophageal thermal injury caused by food has been reported to occur mostly after drinking hot liquid food, and is known to produce alternating white and red linear mucosal bands. In addition, thermal injury caused by ingestion of hot solid foods is documented to be a cause of esophageal ulcers or pseudomembranes. From January 2006 to August 2012, five patients with suspected esophageal thermal injury underwent esophagogastroduodenoscopy with biopsy. A "candy-cane" appearance was observed in one case, pseudomembrane was observed in two cases, an esophageal ulcer was observed in one case, and a friable and edematous mucosa was noted in one case. We believe that the endoscopic findings of esophageal thermal injury depend on the following factors: causative materials, amount of food consumed, exposure period, and time to endoscopy after the incident. Therefore, physicians who encounter patients with suspected esophageal thermal injury should carefully take the patient's history considering these factors.

To evaluate the efficacy and safety of propofol and midazolam for sedation during esophagogastroduodenoscopy (EGD) in children.
We retrospectively reviewed the hospital records of 62 children who underwent ambulatory diagnostic EGD during 1-year period. Data were collected from 34 consecutive patients receiving propofol alone. Twenty-eight consecutive patients who received sedation with midazolam served as a comparison group. Outcome variables were length of procedure, time to recovery and need for additional supportive measures.
There were no statistically significant differences between the two groups in age, weight, sex, and the length of endoscopic procedure. The recovery time from sedation was markedly shorter in propofol group (30±16.41 minutes) compared with midazolam group (58.89±17.32 minutes;
Intravenous administered propofol provides faster recovery time and similarly safe sedation compared with midazolam in pediatric patients undergoing upper gastrointestinal endoscopy.
