A 75-year-old man is brought to the emergency department due to acute-onset profuse vomiting of large amounts of bright red blood. He has had intermittent, dull epigastric pain for the last 3 months. Medical history is significant for chronic obstructive pulmonary disease with multiple exacerbations and lumbar spinal stenosis. The patient has smoked 1 pack of cigarettes daily for 40 years. Blood pressure is 70/40 mm Hg and pulse is 120/min. Examination shows epigastric tenderness. The patient dies an hour after admission despite resuscitation efforts. Autopsy shows a deep peptic ulcer localized proximally on the lesser curvature of the stomach. The ulcer most likely penetrated which of the following arteries? A. Common hepatic (1%) B. Gastroduodenal (9%) C. Inferior pancreaticoduodenal (0%) D. Left gastric (75%) E. Right gastroepiploic (6%) F. Splenic (5%) G. Superior mesenteric (0%)

A 45-year-old man with alcoholism is admitted to the hospital for acute pancreatitis. He initially responds well to bed rest and intravenous fluid, but 1 week later he has persistent fever and epigastric pain. His temperature is 38.6°C (101.5°F). Abdominal examination shows a tender epigastric mass. Laboratory studies show a leukocyte count of 13,500/mm3 and serum amylase activity of 300 U/L. Which of the following is the most likely cause of these findings? A) Acute gastric dilatation B) Carcinoma of the stomach C) Chronic pancreatitis D) Cystic adenocarcinoma of the pancreas E) Pancreatic pseudocyst F) Perforated gastric ulcer with abscess
