aP-value was calculated between patients with right-side esophageal diverticulum and patients with left-side esophageal diverticulum.

bP-value was calculated between patients with a single esophageal diverticulum and patients with multiple esophageal diverticula.

cType I achalasia was analyzed in patients with type I, type II, and type III achalasia on high-resolution manometry (HRM).

dSigmoid-type achalasia includes advanced sigmoid-type achalasia.

IRP, integrated relaxation pressure.
