General Surgery · Acute abdomen: abdominal compartment syndrome
Sample itemA critically ill patient with massive fluid resuscitation has tense abdominal distension, oliguria, rising ventilatory pressures, and shock. What syndrome should be considered?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
B. Abdominal compartment syndrome
Abdominal compartment syndrome occurs when raised intra-abdominal pressure causes new organ dysfunction, including renal failure, ventilatory compromise, and shock. Pressure measurement and urgent decompressive strategies may be needed.
Option by option
A. Renal colic
Renal colic does not cause tense abdominal distension and ventilatory pressure rise.
B. Abdominal compartment syndrome (correct)
Correct. Multiorgan dysfunction with tense abdomen after resuscitation is highly suggestive.
C. Uncomplicated ascites
Ascites alone does not define compartment syndrome.
D. Simple postoperative ileus
Ileus causes distension but not necessarily severe pressure-related organ failure.
