Gastro: Chronic Pancreatitis: Free MSRA Podcast

⚕️FREE MSRA PODCAST –Chronic Pancreatitis🎧 A clear, high-yield breakdown of this irreversible pancreaticinflammation & insufficiency –perfect for exam prep and real-life clinical scenarios. 🧠 Key Learning Points📌 Definition• Long-standinginflammation of the pancreas causing permanent structural damage and loss ofboth exocrine (enzyme) and endocrine (insulin) function.📌 Causes & Risk Factors• Alcohol misuse(60–70 % of UK cases)• Cigarette smoking(independent risk)• Genetic mutations– PRSS1, SPINK1, CFTR• Autoimmunepancreatitis (IgG4-related)• Obstructivelesions – gallstones, strictures, tumours, pancreatic divisum• Metabolic:hypertriglyceridaemia, hypercalcaemia• Recurrent acutepancreatitis, abdominal trauma, ERCP-induced injuryMnemonic – TIGAR-OT Toxic-metabolic (alcohol, drugs,hyperCa/TG) I Idiopathic G Genetic AAuto-immune R Recurrent severe acuteattacks O Obstructive📌 Pathophysiology• Premature enzymeactivation → autodigestion• Chronicinflammation & oxidative stress → fibrosis and ductal strictures• Progressive acinaratrophy → exocrine insufficiency; islet loss → diabetes📌 Symptoms• Chronic epigastricpain radiating “boringly” to the back• Steatorrhoea(pale, oily, foul stools) & weight loss• Nausea, vomiting,malnutrition, fat-soluble vitamin deficiency• Brittle diabetesmellitusMnemonic – PAIN-D (Pain, steAtorrhoea, Insufficiency-exocrine,Nutrient loss, Diabetes)📌 Differential Diagnosis• Acute pancreatitis• Peptic-ulcerdisease / perforation• Biliary colic orcholecystitis• Chronic mesentericischaemia• Pancreatic cancer• Functionaldyspepsia / IBS📌 Diagnosis• CT or MRI/MRCP:pancreatic calcifications, ductal dilation / strictures• Endoscopicultrasound (EUS) for subtle early disease ± FNA• Faecal elastase< 200 µg/g → exocrine insufficiency• Serumamylase/lipase ↑ only during flares• Secretinstimulation or ¹³C-mixed triglyceride breath test if equivocalQuick memory tip: Pain + Pancreatic calcifications on CT = Chronic Pancreatitis.📌 Management• Lifestyle: absolute alcohol & smokingcessation, low-fat diet, dietitian input• Analgesia ladder →consider coeliac plexus block, neuromodulators, SCS• PERT: pancreatic enzyme replacement with meals& ADEK vitamins• Glycaemic control:metformin / insulin for pancreatogenic diabetes• Endoscopic therapy– ERCP stone extraction, stricture stenting, lithotripsy• Surgery forlarge-duct disease or refractory pain (Puestow, Frey, Whipple, totalpancreatectomy ± islet auto-transplant)• NICE priorities:early specialist HPB referral, regular nutritional & diabetes review, DEXAscreening for osteoporosis📌 Complications• Pancreaticpseudocyst or walled-off necrosis• Bile-duct orduodenal obstruction• Splenic veinthrombosis & portal hypertension• Malnutrition &osteopaenia/osteoporosis• Pancreaticadenocarcinoma (↑ lifetime risk)📌 Prognosis10-year survival ≈70 %; falls markedly with ongoing alcohol use, smoking, or development ofpancreatic cancer. Pain, malabsorption and diabetes often require lifelongmultidisciplinary care. 📎 More MSRA Resources for Chronic Pancreatitis📝Revision Notes: https://www.passthemsra.com/topic/chronic-pancreatitis-revision-notes/🧠Flashcards: https://www.passthemsra.com/topic/chronic-pancreatitis-flashcards/💬Accordion Q&ANotes: https://www.passthemsra.com/topic/chronic-pancreatitis-accordion-qa-notes/🚀Rapid Quiz: https://www.passthemsra.com/topic/chronic-pancreatitis-rapid-quiz/🎓Full Course: https://www.passthemsra.com/courses/gastroenterology-for-the-msra/ Hashtags#MSRA #MSRARevision#MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards #MSRAQ&ANotes#MSRAAccordions #MultiSpecialityRecruitmentAssessment #MSRAOnlineRevision#MSRARevisionWebsite #ChronicPancreatitis
