食管上段尤其在环咽肌下方是异物的多发部位，在该处食管镜手术操作最困难也最易发生器械性损伤。儿童气管弹性差，食管镜尚有压迫气管引起窒息的危险。我们自1994年8月起选择性地对食管上段钝性异物在直达喉镜下用细齿鳄口异物钳伸入食管腔央取共9例。其中成功取出8例，包括］ The upper esophagus, especially in the lower part of the cricoid pharynx is a foreign body multiple sites where esophageal surgery is the most difficult and most likely to cause mechanical damage. Children tracheal flexibility is poor, esophageal mirror still has the risk of suffocation caused by tracheostomy. We have since August 1994 selectively blunt upper esophageal foreign body in the direct laryngoscope with small crocodilian foreign body forceps into the esophageal cavity for a total of 9 cases.
