HPI:
Patient is a 41 year old white male who presents complaining of 2 weeks of abdominal pain and distention. The pain is diffuse, dull and has gradually become more epigastric in location for the previous 1-2 days. It has been of varying intensity, but never completely relieved. The patient's pain continued to worsen and became sharp, primarily in the epigastrium. He vomited once on the day of his ED evaluation. He was seen by his PMD 9 days ago for these symptoms and was prescribed dicyclomine as well as an emema which gave him mild relief. An abdominal ultrasound was performed 3 days ago for continued symptoms and revealed some gallbladder sludge, mild diffuse ascites and a 1cm right renal cyst. There were no gallstones and the biliary ducts appeared intact. The pancreas was normal. The patient developed loose stools subsequently. Stool for ova and parasites was performed on 3 specimens and was normal. The patient reports having a similar episode 3 years ago.
