Even More Pain

A 65 year old man presents with pain in the left upper abdomen, which started abruptly around an hour ago. He has also experienced several episodes of vomiting since.

His medical history is significant for type 2 diabetes, which was diagnosed 5 years ago, and is currently well controlled on metformin 1g/day. His surgical and family histories are unremarkable.

He has smoked 20 pack years in total, but stopped doing so around 6 months ago. He only drinks socially.

A complete blood count, renal profile, liver profile, and amylase and lipase levels are within normal limits, while a random capillary glucose is 127 mg/dL.
