Esophageal function was investigated after 1 to 8 years in five consecutive patients surviving spontaneous esophageal rupture (Boerhaave's syndrome) and treated by suturation. Only one patient was symptom free and had almost normal esophageal function as judged by manometry, 24-hour pH monitoring, endoscopy, and barium swallow. In the other four patients reflux symptoms and a severe functional disturbance of the esophagus were observed. In four patients the manometry revealed a lack of propulsive peristaltic movements and esophageal muscular incoordination (particularly in the upper part of the esophagus) closely mimicking those seen in the nonspecific esophageal motility disorder. In 24-hour intraesophageal pH monitoring a pathologic gastroesophageal reflux with long-lasting single reflux periods was observed, suggesting poor esophageal clearance. Also endoscopic and histologic signs of reflux esophagitis were seen in the same four patients. In contrast, lower esophageal sphincter pressure was normal in all five survivors. It is concluded that patients with spontaneous esophageal rupture have a severe disturbance of esophageal motility. The concomitant reflux esophagitis may be caused primarily by the esophageal motility disturbance, which may also contribute to the origin of the rupture.

For more than 2 centuries, the nature and pathophysiology of pharyngoesophageal (Zenker's) diverticulum has been a matter of argument. The intrinsic or extrinsic forces and structures that might play a role in the development of this disorder have been repeatedly scrutinized, and still today the different theories of muscular incoordination and/or spasm, cricopharyngeal achalasia, gastroesophageal reflux, or neuromuscular abnormalities try to find their way as the final word regarding etiology remains to be told. Options for treatment follow a similar pattern although myotomy and diverticulopexy seem to have yielded the best results. In this review, historical and current data gathered from the world literature are compiled in an attempt to give a clear overview of the pathophysiology surrounding the genesis of Zenker's diverticulum and the clinical manifestations, diagnosis, and different alternatives for definite treatment of this disorder.
