🍐 In this episode of PodBites, Tariq Makhzoum and Amro Badra guide you through lower GI disorders — from common anorectal conditions to life-threatening mesenteric ischemia — using clinical cases, anatomy-based reasoning, and high-yield diagnostic and management principles.

🎙️ Tune in to explore:

  • The definition and causes of lower GI bleeding, including hemorrhoids, fissures, diverticular disease, and ischemia
  • The importance of the dentate line and how it explains differences in pain, bleeding, and management
  • Hemorrhoids, including internal vs external classification, clinical presentation, and treatment options
  • Anal fissures, their association with constipation, and the role of topical calcium channel blockers, nitrates, and surgical management
  • Perianal abscesses and fistulas, their pathophysiology, clinical features, and definitive surgical treatments
  • Rectal prolapse, key exam findings like concentric folds, and the role of rectopexy as definitive management
  • Acute mesenteric ischemia, including embolic, thrombotic, venous, and non-occlusive causes, and why it’s a true vascular emergency
  • Chronic mesenteric ischemia, the concept of intestinal angina, and the role of revascularization in restoring blood flow

    • 🌟 A structured, high-yield guide to understanding lower GI disorders, helping you connect anatomy, vascular physiology, and clinical management with confidence.
