Gastrointestinal Disease Diagnosis & Management Handbook: Comprehensive Coverage of Pathophysiology, Clinical Evaluation, and Evidence-Based Therapeutics for Internal Medicine Residents

A patient arrives with three weeks of vague abdominal pain, a normal lipase, calcified pancreas on an old scan, and a team about to call it "not the pancreas" — and the wrong fork here costs months. Treat gastrointestinal and liver disease as broad categories — "abnormal liver tests," "rectal bleeding," "a pancreatic mass" — and you stage the tumor too late, stent before imaging, restrict protein in encephalopathy, and starve the cirrhotic you meant to save. This handbook trains one habit across thirty-eight chapters: stop at the decision fork that actually changes management, and act on it with confidence at the bedside. Inside this book: • Resuscitate before the scope — manage the hemodynamically significant bleed in the right order, including the variceal bundle most teams give late. • Classify before you test — read the hepatocellular-versus-cholestatic pattern first and stop ordering the wrong liver workup. • Stage before you stent — protect transplant eligibility and curative options in biliary and pancreatic malignancy. • Diagnose pancreatitis clinically — resist the day-one CT, the prophylactic antibiotics, and the prolonged fast. • Never restrict protein in hepatic encephalopathy — reverse the myth that accelerates the sarcopenia that kills. • Decode the GI Clinical Reasoning Engine — a branded decision-fork system embedded in every chapter and consolidated into a master compendium indexed by complaint, organ, and urgency. • Drill 55 vignettes — rehearse the fork until it becomes automatic under pressure. Written for internal medicine residents, hospitalists, internists, family physicians, gastroenterology fellows, NPs, PAs, and the students who round with them. Open it before your next admission — and decide better for every patient who follows.
