The document discusses intestinal obstruction, outlining its pathophysiology, classifications (dynamic and adynamic), and causes such as adhesions, volvulus, and intussusception. It highlights key features for diagnosis, imaging techniques, and treatment options, including surgical interventions. Various types of mechanical obstructions and specific conditions like acute intussusception are also covered.
Intestinal obstruction
- 1. Intestinal Obstruction Prepared by : A.A.A Under supervision : Dr Mohemed Hazim
- 2. Objective • To understand: • The Pathophysiology of dynamic and Adynamic intestinal obstruction • The Cardinal features on history and examination • • The Causes of small and large bowel obstruction • • The Indications for surgery and other treatment options in bowel obstruction
- 3. CLASSIFICATION classified into two types: • Dynamic • Adynamic
- 6. STRANGULATION Causes of strangulation ■ Direct pressure on the bowel wall Hernial orifices Adhesions/bands ■ Interrupted mesenteric blood flow Volvulus Intussusception ■ Increased intraluminal pressure Closed- loop obstruction
- 8. SPECIAL TYPES OF MECHANICAL INTESTINAL OBSTRUCTION • Internal hernia • Obstruction from enteric strictures • Bolus obstruction : Gallstones , food , Trychobezoars and phytobezoars , Stercolith and worms.
- 9. Obstruction by adhesions and bands
- 10. Acute intussusception • This occurs when one portion of the gut invaginates into an immediately adjacent segment; almost invariably, it is the proximal into the distal.
