Recommendations are actually from American Association for the Study of Liver Diseases (AASLD) to obtain US every 6 months +/- AFP (with risk factors)

dysphagia, odynophagia, unintentional weight loss, gastrointestinal bleeding (including hematemesis or melena), persistent vomiting, and unexplained iron deficiency anemia.
What condition causes an unreliable LDL calculation?
Hypertriglyceridemia causes an unreliable low-density lipoprotein LDL calculation, particularly when using the Friedewald formula.
The Friedewald equation assumes a fixed ratio of triglycerides to very low-density lipoprotein cholesterol (VLDL-C), which becomes inaccurate as triglyceride levels rise, especially above 150 mg/dL (1.7 mmol/L), and is considered invalid when triglycerides exceed 400 mg/dL (4.5 mmol/L)
As per Dr. Moon, how long is a small intestine likely to be?
>200cm
The small intestine in adults typically measures between 300 cm and 800 cm in length, with considerable inter-individual variability. Most intraoperative measurements in living adults report mean lengths around 450–500 cm, though cadaveric studies and some surgical series have found ranges extending up to 800 cm or more
