Abstract
The most serious injury accompanying esophagoscopy would be the rupture of the esophageal wall at the orifice of the esophagus.
This complication has been reported by some to occur from 0.3 to 1% of all the diagnostic esophagoscopy.
In order to avoid the complication the surgeon must be aware of detailed anatomical as well as histological structure of the region.
The authors describe anatomy and histology at the particular area and safe technique of esophagoscopy, and then propose that the junction of the cricopharynge al and thyropharyngeal muscles should correctly be called as “Killian's weak area”.
