Cardiac arrhythmias on swallowing.

A middle-aged male patient with cardiac arrhythmias on swallowing due to incoordinate peristaltic activity of the esophagus is reported. Medical treatment with propranolol and quinidine sulfate made the symptoms manageable initially but recurrence of symptoms made surgical treatment desirable. Barium sulfate with apple produced the incoordinate peristalsis with resultant arrhthmias as soon as it arrived at the junction between the middle and lower third of the esophagus. This was followed by a normal peristaltic wave which cleared the esophagus and brought the cardiac rhythm back to normal again. Balloon distension of the esophagus located the afferent stimuli as arising from the lower third of the esophagus. A circular esophageal myotomy at the junction of the middle and the lower third, although not completely abolishing the reflex, has made the symptoms less severe. However, this procedure has produced considerable ballooning of the mucosa at the myotomy site, and has resulted in some difficulty in swallowing.

Observations on oesophageal length.

The subject of oesophageal length is discussed. The great variations in the length of the oesophagus in individual patients is noted, and the practical use of its recognition in oesophageal surgery is stressed. An apprasial of the various methods available for this measurement is made; this includes the use of external chest measurement, endoscopic measurement, and the measurement of the level of the electrical mucosal potential change. Correlative studies of these various methods are made, and these show a very high degree of significance. These studies involved simultaneous measurement of external and internal oesophageal length in 26 patients without a hiatal hernia or gastro-oesophageal length in 26 patients without a hiatal hernia or gastro-oesophageal reflux symptoms, 42 patients with sliding type hiatal hernia, and 17 patients with a peptic stricture in association with hiatal hernia. The method of measuring oesophageal length by the use of the external chest measurement, that is, the distance between the lower incisor teeth and the xiphisternum, measured with the neck fully extended and the patient lying supine, is described in detail, its practical application in oesophageal surgery is illustrated, and its validity tested by internal measurements. The findings of this study demonstrate that the external chest measurement provides a mean of assessing the true static length of the oesophagus, corrected for the size of the individual.

Palliative push-through intubation for malignant obstruction of the gastroesophageal junction.

Methods available for palliative intubation of the gastroesophageal junction for malignant obstruction are discussed. In a previous report from this unit, we noted that the push-through method with a Souttar tube is superior in many respect to the pull-through method with the Mousseau-Barbin tube in cases of esophageal carcinoma. However, a push-through method at the cardia, although highly desirable, had not yet been employed because of safety reasons. This paper describes a technique to overcome the dangers of push-through intubation at the gastroesophageal junction and reports its successful use in 16 patients.
