High-Yield General Surgery & Abdominal Anatomy Review for the CST Exam

Welcome to this comprehensive General Surgery review, specifically tailored for college Surgical Technologist students preparing for the CST certification exam! In this focused overview, we break down the most highly tested anatomical landmarks, surgical terminologies, and complex procedural steps you absolutely must know for abdominal and general surgeries . Grab your notebook and get ready to master everything from the Triangle of Calot to Hesselbach's Triangle! 🔑 Key Takeaways & Topics Covered: Abdominal Wall Layers & Incisions: Knowing the exact order of tissue layers when entering the abdominal cavity is vital, starting from the skin, down through the subcutaneous fat, Scarpa's fascia, the muscle layers, the transversalis fascia, and finally the parietal peritoneum . We also cover why the linea alba (a wide, flat tendon known as an aponeurosis) is the ideal location for a midline incision because it is tough and easy to suture . Gastrointestinal Pathologies: A breakdown of critical terms like volvulus (a twisting of the bowel) and intussusception (when the bowel "telescopes" or pushes into itself) . We also review how an anastomosis connects two tubes together, often utilizing techniques like a purse-string suture alongside an EEA stapler . Gastric & Pancreatic Surgeries: Master the difference between a Billroth 1 (gastroduodenostomy), a Billroth 2 (gastrojejunostomy), and a Roux-en-Y total gastrectomy . We also dissect the Whipple procedure, a massive surgery for pancreatic cancer that routinely removes the head of the pancreas, the duodenum, and the gallbladder to prevent metastasis . Biliary Anatomy & Landmarks: You must know the Triangle of Calot, which is an incredibly important landmark for a cholecystectomy formed by the cystic duct, cystic artery, and common hepatic duct . We also review the exocrine functions of the pancreas (releasing digestive juices via the Ampulla of Vater) and its endocrine functions (producing insulin via the Islets of Langerhans) . Hernia Classifications: The absolute must-know anatomical boundaries of Hesselbach's Triangle, which is formed by the rectus abdominis, inguinal ligament, and inferior epigastric vessels . Remember the golden exam rule: Direct inguinal hernias pass directly through this triangle, while indirect hernias pass outside of it toward the scrotum . Good luck studying, and remember that breaking down complex medical terms into their roots and suffixes (like -ostomy vs. -ectomy) will help you navigate any tricky general surgery questions on exam day!
