All patients underwent this procedure to treat malignant tumors located in the distal esophagus or at the gastroesophageal junction, and patients had no signs of anastomotic leaks following surgery.

Esophageal cancer (EC) is an aggressive malignancy with a poor prognosis, with its development and progression potentially influenced by changes in the esophageal microbiome.

With primary peristalsis, note that the delay in onset of depolarization, spike burst, and esophageal contraction in the distal esophagus relates to a marked secondary hyperpolarization (arrow).
