Overview
The exact pathogenesis of Mallory-Weiss syndrome is not fully understood. It is thought that Mallory-Weiss syndrome is the result of sudden increase in intraabdominal pressure that causes mucosal lacerations.
Pathogenesis
- The exact pathogenesis of Mallory-Weiss syndrome is not fully understood.
- It is thought that Mallory-Weiss syndrome is the result of sudden increase in intraabdominal pressure that causes mucosal lacerations. If the tear involves the esophageal venous or arterial Plexus,bleeding occurs.[1][2]
Genetics
There are no genes involved in the pathogenesis of Mallory-Weiss syndrome.
Gross Pathology
On gross pathology, Mallory-Weiss tears may appear red longitudinal break in the mucosa, sometimes may extend into muscularis mucosa, and covered by a clot. Active bleeding may also be observed.
