Instrumental perforation of the esophagus in benign disease.
Over a period of seven years, a total of 1,831 endoscopic procedures were performed in patients with benign esophageal disease. These comprised flexible esophagoscopy (848), flexible esophagoscopy and dilation (924), pneumatic dilation (29), and rigid esophagoscopy (30). There were 14 episodes of perforation: 1 was cervical, 2 were abdominal, and 11 were perforations of the intrathoracic esophagus (7 occurred at or immediately above a stricture). The diagnosis was made immediately in 9 and within six hours in all but 1 patient. Treatment was emergency surgery in 12 patients, 2 of whom died. The major cause of death was respiratory failure. The overall incidence of perforation was 0.76%. The incidence of perforation was 0.35% (3/848) for flexible esophagoscopy alone, 0.38% (3/792) for dilation with Maloney mercury-weighted bougies, and 3.8% (5/132) for dilation with other bougies. Our experience indicates that instrumental perforation in benign esophageal disease carries a considerable mortality rate in spite of prompt recognition and surgical treatment. Successful dilation with mercury-weighted bougies can be achieved in 86% of benign strictures with an incidence of perforation similar to that for flexible esophagoscopy alone. Difficult strictures and the use of other bougies are associated with a tenfold higher incidence of perforation.
