Handbook of Clinical Scenarios in Surgery

Name the Signal, Cross the Threshold, Make the Call This handbook organizes general surgery around the decisions that define it - not as a disease catalog but as a structured progression from clinical scenario to operative threshold to action. It builds from the pathophysiology of each surgical condition through the specific signals that separate observation from intervention, equipping the reader to recognize the moment when watchful waiting stops being safe. Twenty-three chapters span perioperative optimization, the alimentary tract, hepatobiliary and pancreatic disease, endocrine and breast surgery, trauma, soft tissue infections, and postoperative emergencies - each anchored by the Operative Threshold System, a five-part decision framework embedded in every major topic. Algorithms rendered as decision-tree prose, annotated imaging placeholders, and clinical cases written as guided reasoning turn dense surgical pathophysiology into bedside action. What This Book Puts in Your Hands • Recognize the operative threshold in equivocal presentations - serial examination logic, trajectory reading, and the named signals experienced surgeons use but rarely articulate. • Manage the acute abdomen by scenario - from perforated peptic ulcer timing to Hinchey-staged diverticulitis to mesenteric ischemia revascularization-versus-resection decisions. • Navigate hepatobiliary thresholds - critical view of safety, bile duct injury recognition, pancreatic head mass resectability without preoperative biopsy, and HCC treatment selection by hepatic functional reserve. • Select the correct trauma intervention in real time - FAST-to-hemodynamics decision logic, blunt aortic injury timing, selective stab wound management, and the mangled extremity salvage-versus-amputation calculus. • Distinguish necrotizing fasciitis from cellulitis before the late signs appear - threshold signals, the finger test, and the principle that a negative exploration always beats a delayed one. • Identify anastomotic leak by trajectory - the postoperative day five tachycardia pattern that separates leak from routine recovery, hours before imaging confirms it. Open it before your next call night - the operative thresholds your patients depend on, named and structured in one reference.
