 The patient is a 28-year-old, who is status post gastric bypass surgery nearly one year ago.  He has lost about 200 pounds and was otherwise doing well until yesterday evening around 7:00-8:00 when he developed nausea and right upper quadrant pain, which apparently wrapped around toward his right side and back.  He feels like he was on it but has not done so.  He has overall malaise and a low-grade temperature of 100.3.  He denies any prior similar or lesser symptoms.  His last normal bowel movement was yesterday.  He denies any outright chills or blood per rectum.
