History of Present Illness
Steven Johnson is a 49-year-old male who presented to the emergency department 5 days ago with a history of worsening diffuse abdominal pain and vomiting. During the workup in the emergency department, a contrast-enhanced CT scan of the abdomen was ordered that showed inflammation and necrosis involving less than 15% of the pancreas. The patient was started on IV fluids, meropenem 1 g q 8 h plus vancomycin 1 g q 12 h. The patient underwent an exploratory abdominal laparotomy, which revealed inflammation of the common bile and stones in the gallbladder requiring cholecystectomy. The patient was subsequently transferred to the surgical ICU for postsurgical care where he remained in a guarded condition and extubated, but has developed a new fever in the last 24 hours on broad-spectrum antibiotic therapy.
