different surgical procedures. We could find only two cases of colonic interposition for esophageal stricture with EBD [2,3]. The anesthetic methods were different, and the procedures were shorter than those used in our case. There was only one patient with EBD who underwent a reconstructive operation of 12 h duration [4]. Because of the paucity of the literature on anesthesia of long duration in patients with EBD, we report the anesthetic technique employed in a 12-year-old girl with EBD who underwent a colonic interposition operation of more than 10 h duration.
Case reportThe patient was a 12-year-old-girl, 125 cm tall and weighing 24 kg. She had a history of EBD since birth, and she was admitted for investigation of vomiting. A mid-esophageal stricture was shown by barium esophagogram. On physical examination, her body surface was covered with numerous blisters and with fresh and scattered bullae, particularly involving the face, the extensor sides of the extremities, and around the mouth and nose. There was evidence of microstomia, poor dentition, and limited temporomandibular joint mobility. There were also flexion contractures of the fingers of both hands (Fig. 1). The preoperative hemoglobin level was 10.3 g·dl Ϫ1 . Serum electrolytes, protein, and blood urea nitrogen were within normal limits. She had been treated with corticosteroids in the past, but at the time of admission she was taking phenytoin and was applying hydrocortisone ointment 0.5% to her lesions.The patient was taken to the operating room without premedication, and she placed herself on the operating table, which was fitted with cotton rolls. Anesthesia was induced with vital capacity inhalation of sevoflurane in combination with nitrous oxide and oxygen by a disposable face mask. A 25 G intravenous cannula was inserted in the right forearm, and an
