This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Bleeding from the GUT and diseases of esophagus, Subject name: Medicine
Gastro-esophageal tear is best detected with: 
Select and explain. 
A. CT, B. Angiography, C. UGI endoscopy, D. Barium swallow
C: UGI endoscopy
Answer: C: UGI endoscopy 
Explanation: Endoscopy technique is the procedure of choice for both diagnosis and therapy of these lesions. Endoscopic diagnosis of a Mallory-Weiss tear is readily made by identifying active bleeding, an adherent clot, or a fibrin crust over a mucosal split within or near the gastroesophageal junction. A contact thermal modality, such as multipolar electrocoagulation (MPEC) or heater probe, with or without epinephrine injection, is typically used to treat an actively bleeding Mallory-Weiss tear . Angio-therapy with either selective vasopressin infusion or embolization of the left gastric aery can be performed in patients whose lesions have failed to respond to endoscopic therapy or who are at high risk of endoscopic complications
