What is a characteristic appearance of a Mallory Weiss tear on endoscopy?

A Mallory-Weiss tear is characterized by a linear mucosal tear in the esophagus, typically at the gastroesophageal junction. This manifestation occurs due to the forceful vomiting or retching that increases intra-abdominal pressure, leading to a tear in the mucosa. During endoscopy, these tears appear as thin, linear lacerations that often extend vertically.

This distinct linear appearance is important to recognize because it helps differentiate Mallory-Weiss tears from other types of gastrointestinal injuries or pathologies that might present with different characteristics, such as ulcers or erosions. Understanding this specific presentation is crucial for making an accurate diagnosis and determining the appropriate management for a patient experiencing upper gastrointestinal bleeding related to this condition. Other types of damage, such as circumferential ulceration or polypoid lesions, do not align with the defining features of a Mallory-Weiss tear and signify entirely different clinical issues.
