A 45-year-old man with a long history of alcohol intake comes into the emergency room with upper gastrointestinal (UGI) bleeding. Urgent endoscopy reveals the following findings. Which of the following is the most likely diagnosis?
**Core Concept**
The question is testing the ability to identify the most likely diagnosis for upper gastrointestinal (UGI) bleeding in a patient with a long history of alcohol intake. This requires an understanding of the pathophysiology of UGI bleeding and the common causes in patients with chronic alcoholism.
**Why the Correct Answer is Right**
In patients with chronic alcoholism, the most common cause of UGI bleeding is gastric varices, which are enlarged veins in the stomach and esophagus. This occurs due to portal hypertension, which is a complication of liver cirrhosis caused by chronic alcohol abuse. The increased pressure in the portal vein leads to the formation of collateral veins, including gastric varices, which are prone to bleeding.
**Why Each Wrong Option is Incorrect**
* **Option A:** Gastric ulcers are a common cause of UGI bleeding, but they are not the most likely diagnosis in a patient with a long history of alcohol intake.
* **Option B:** Esophageal candidiasis is a fungal infection that can cause UGI bleeding, but it is not directly related to chronic alcoholism.
* **Option C:** Mallory-Weiss tears are a type of mucosal tear in the esophagus that can cause UGI bleeding, but they are not the most likely diagnosis in a patient with a long history of alcohol intake.
**Clinical Pearl / High-Yield Fact**
The CAGE questionnaire is a useful tool for screening patients for alcoholism: C (cut down on drinking), A (annoyed by others' criticism of drinking), G (guilty about drinking), and E (eye-openers, or drinking first thing in the morning). Patients with a positive response to two or more of these questions are at high risk for alcoholism.
**Correct Answer:** . Gastric varices
