I'll look up the medical library skill first, then search for esophageal varices treatment.

Now let me search the medical library and PubMed in parallel.

Good results. Let me read the most comprehensive sections - Sleisenger (GI Bible) and Goldman-Cecil (clinical medicine), plus the emergency medicine section, in parallel.

Excellent. I have the main content from Sleisenger. Let me read more of that key section and also the Goldman-Cecil section on treatment at line 3637.

I now have very rich content from Sleisenger covering all three treatment phases. Let me fetch the algorithm figure and compile the comprehensive answer.
