Incidence of Zenker's diverticulum with hiatus hernia

Abstract:
The concomitant occurrence of Zenker's diverticulum and hiatus hernia in several patients prompted an investigation to determine whether there is a statistically significant increased incidence of hiatus hernia in patients with Zenker's diverticulum. Radiologic reports contained in 104 charts of patients from the University of Iowa with a diagnosis of Zenker's diverticulum were analyzed retrospectively for the presence of hiatus hernia. Radiologic reports contained in charts of a control group of patients, who had a barium swallow for work-up of a head and neck malignancy, were also analyzed. The control group had a 16% incidence of hiatus hernia, which was consistent with published data. The Zenker's diverticulum group had a 39% incidence of hiatus hernia, a statistically significant increase over the control group. The pathophysiology linking these conditions and the clinical implications of their relationship are discussed.

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
