General Surgery · Intestinal obstruction: strangulation
Sample itemIn a patient with small bowel obstruction, which finding most suggests strangulation?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
A. Constant severe pain with fever, tachycardia and localised tenderness
Strangulation compromises blood supply, causing continuous pain, systemic inflammatory response, peritonism and leucocytosis with raised lactate. Colic with visible peristalsis is simple obstruction. Strangulation demands early operation to avoid gangrene and perforation.
Option by option
A. Constant severe pain with fever, tachycardia and localised tenderness (correct)
Correct. Continuous pain with toxicity indicates ischaemic bowel.
B. Colicky pain that comes in waves with high-pitched bowel sounds
Colicky pain with hyperactive sounds is typical of simple mechanical obstruction.
C. Absolute constipation alone
Absolute constipation occurs in simple obstruction too.
D. Vomiting with visible peristalsis
Visible peristalsis shows active attempts to overcome the obstruction.
