Upper GI Bleed Causes- Overview

Watching these videos after being diagnosed with Dieulafoy's lesion. Healthy 40 year old female. Had just came back from vacation lots of wine and aspirin. Blood transfusion and clips to stop the bleeding. My grandfather died from the same condition. Thank you for the video

You are brilliant at making things so easy to understand. Thank you doctor! :)

Love your videos :) It's worth underscoring that the stress etiology in Ulcers/Gastritis isn't the daily modern day life stress. Rather it's patients who are critically ill and under massive physiological stress. Examples being prolonged intubation, sepsis, severe head trauma and extensive burns.

as always, very helpful 👍 thx so much for the videos. keep up the amazing work

You're the man! Thanks for all the help 🔥🔥🔥🔥🔥🔥🔥🔥

That is awesome as always.Thank you.

These are always amazing videos

Thank you so much, I always find inspiration from your lessons ^^

Excellent video.

I can't imagine medical school without his videos 😍😍😍 very helpful

Upper GI bleeding can cause hematoemesis (vomitting blood). Causes: Esophagitis (reflux/GORD, infective, chemifally irritated & eosinophilic) . Barrett's oesophagus = metaplasia of last 1/3 of the oesophagus from squamous epithelium to Barrett's metaplasia (+ goblet cells) which can produce adenocarcinoma. . Oesophageal varices result from portal hypertension. These dilated veins draining the oesophagus can rupture. Diagnosis is done via endoscopy. Esophagus vein and left gastric vein drain the esophagus, they anastomose, and they drain to the portal vein to the liver. If you have portal hypertension as in liver cirrhosis, backflow of blood results in esophageal varices. . Mallory-Weiss Syndrome = longitudinal superficial tears near the cardio-esophageal junction (cardia of the stomach meets esophagus). Its associated with chronic vomitting, coughing, retching and straining. . Erosive gastritis = gastric mucosal erosion after damage to mucosal defense. Symptoms = bleeding Diagnostic = endoscopy Treatment = proton pump inhibitors/H2 blockers to stop acid secretion Causes = stress, use of NSAIDs, Alcohol. . Mass lesions in the esophagus can be polyps, and tumours (adenocarcinoma or squamous cell carcinoma). Benign tumours of the stomach: inflammation and hyperplastic polyps Fundic gland polyps Gastric adenomas Malignant tumours of the stomach Gastric carcinoma Gastric lymphoma Carcinoid tumours Stromal cell tumours . Dieulafoy's lesion = calibre persistent artery This is rare. It is life-threatening as it causes hemorrhage of GI tract. A bulging of a lesion that could rupture causing severe fatal internal bleeding. . Angiodysplasia is a common vascular abnormality in GI tract, similar to Telangiectasia Morphology: there are elastic, dilated, thin-walled vessels lined by Endothelium alone. Its most common in in the colon. Diagnosis: Endoscopy . Ulceration = erosion of the mucous membrane Similar risk factors to gastritis. Excess HCL secretion caused by H. Pylori infection, NSAID use, stress. Duodenal ulcers are more common than gastric. Bleeding, perforation, narrowing and obstruction are possible complicagions with ulceration.

some doctors should see your videos before they start to teach us. you made every topic so easy

It was very helpful because of worthy explanation and attractive illustrations

Awesome video, Thank you !!!

best videos ever thank u so much

nice and easy to understand , thanks

How do you make your videos ? I would like to know :)

thank youuuu!

Superb

Etoh/bulimia/foodpoinsoning -> violent vomiting -> gastro-esophageal tears -> bloodyvomit(hematemesis) -> Mallory-Weiss syndrome Dx: endoscopy Tx: supportive
