Gastro: Diverticular Disease: Free MSRA Podcast

⚕️FREE MSRA PODCAST –Diverticular Disease (Diverticulosis & Diverticulitis)🎧 High-yield audio summary covering definition, diagnosis, andmanagement of Diverticular Disease –from asymptomatic pouches to surgical emergencies. 🧠Key Learning Points📌Definition• Diverticulosis = presence of colonicdiverticula (pouches), usually asymptomatic• Diverticular Disease = symptomaticdiverticulosis• Diverticulitis = inflammation/infection of adiverticulum🧠Tip: “Osis” =pouches, “Itis” = inflammation 📌Causes & RiskFactors• Low-fibre diet → hard stools → ↑ intraluminalpressure• Ageing – most common >50• Obesity, smoking,sedentary lifestyle• NSAID use and chronic constipation🧠Think “LOW-FIBRE +PRESSURE + AGE” 📌Pathophysiology• Mucosal herniationat weak points (esp. near blood vessels)• In diverticulitis:blockage by stool (fecalith) → bacterial overgrowth → inflammation/infection🧠Analogy: Like foodstuck in a pouch → festers → flares up 📌Symptoms✅Diverticulosis: often asymptomatic or mild LLQ pain, bloating,constipation✅Diverticulitis: LLQ pain, fever, nausea, vomiting, tenderness, ↑WCC/CRP✅Diverticular bleeding: sudden, painless PR bleeding,maroon or bright red🧠Red Flags: Sepsis,peritonitis, recurrent UTI from fistula, palpable mass 📌DifferentialDiagnoses• IBS, IBD(UC/Crohn’s)• Gastroenteritis, colorectalcancer, appendicitis, ischaemic colitis, gynaecological causes🧠Always rule out colorectalcancer if symptomsare unclear 📌Diagnosis &Investigations• Bloods: FBC, CRP, U&Es, WCC, Anaemia (ifbleeding)• CT abdomen with contrast = gold standard fordiverticulitis• Colonoscopy (after acute phase) to excludemalignancy• Other tools: US,MRI, stool cultures, cystoscopy if fistula suspected🧠Tip: Avoidcolonoscopy during acute diverticulitis due to perforation risk 📌Management✅Asymptomaticdiverticulosis: no treatment✅Uncomplicateddiverticular disease: – ↑ dietary fibre,hydration, lifestyle change – Bulk-forminglaxatives (e.g., ispaghula husk)✅Diverticulitis: – Mild: oralantibiotics, analgesia, rest – Severe: IVantibiotics, fluids, hospital admission – Emergency:Surgery if perforation, sepsis, abscess✅Bleeding: – Colonoscopy ±embolisation – Surgery ifuncontrolled🧠Avoid NSAIDs/opioidslong-term; Paracetamol preferred 📌Complications• Abscess, Peritonitis,Fistulas (colo-vesical, colo-vaginal)• Bowel obstruction (stricture/scar)• Hemorrhage• Chronic strictures or ongoing inflammation• Rare: potentiallong-term link with colorectal cancer 📌Prognosis &Prevention• Most withdiverticulosis never develop symptoms• Recurrence of diverticulitis possible;complications usually with first episode• Prevention: High-fibre diet, regular exercise,smoking cessation🧠75% of patients withdiverticulosis stay well 📎MSRA Resources forDiverticular Disease📝Revision Notes:https://www.passthemsra.com/topic/diverticular-disease-diverticulosis-diverticulitis-revision-notes/🧠Flashcards:https://www.passthemsra.com/topic/diverticular-disease-diverticulosis-diverticulitis-flashcards/💬Accordion Q&ANotes:https://www.passthemsra.com/topic/diverticular-disease-diverticulosis-diverticulitis-accordion-qa-notes/🚀Rapid Quiz:https://www.passthemsra.com/topic/diverticular-disease-diverticulosis-diverticulitis-rapid-quiz/🎓Full Course:https://www.passthemsra.com/courses/gastroenterology-for-the-msra/ Hashtags#MSRA #MSRARevision#MSRAFlashcards #DiverticularDiseaseMSRA #DiverticulitisMSRA #MSRAAccordions#MSRAQuiz #MSRATextbook #GastroenterologyMSRA #MSRAOnlineRevision#NICEGuidelines
