Types of bowel obstruction High small bowel obstruction • • • • • - Location: occurs in the proximal part of the small intestines -> duodenum and jejunum. Causes: Adhesions (most common cause) Hernias, volvulus or tumours. Clinical features: Severe colicky abdominal pain. Vomiting: often bilious due to proximal bowel obstruction. Abdominal distention. Minimal or no stool passage. Radiographic findings: Dilated small bowel loops. Air fluid levels. Risk strangulations: High risk due to narrow lumen and rapid progression. Low small bowel obstructions • • • • - Locations: Occurs in the distal part of the small bowel obstructions (ileum). Causes: Crohn’s disease Adhesions Hernias Clinical features: Colicky abdominal pain. Vomiting -> less than the high small bowel obstruction. Abdominal distension. Delayed passage of stool and gas. Radiographic findings: Dilated small bowel loops. Air fluid levels. Large Bowel obstructions • • - Locations: Tumours (most common cause) Diverticulitis Volvulus Strictures Clinical features Gradual onset of constipation • - Abdominal distention Minimal vomiting (due to more distal obstruction) Visible peristalsis (in some cases). Radiographic findings: Dilated colon: especially in the sigmoid colon. Bird’s beak: appearance on imaging.
