Difficulty: MediumGastrointestinal and Abdominal Surgery

For each patient presentation described in the surgical emergency and critical care setting below, select the most appropriate primary intervention from the available list.

  • A 35-year-old female with ulcerative colitis presents with a temperature of 39.5°C (103.1°F) and a heart rate of 135 bpm; transverse colon dilation is 8.5 cm. Her condition has progressively deteriorated despite 48 hours of high-dose intravenous corticosteroids.Immediate subtotal colectomy and creation of an end ileostomy
  • A 24-year-old female at 11 weeks gestation reports severe right lower quadrant pain with focal peritonitis; ultrasound confirms a 9 mm, non-compressible blind-ending tubular structure in the right lower quadrant.Prompt laparoscopic appendectomy without delay
  • A 29-year-old male sustains a stab wound to the left flank; vital signs are stable, but a contrast-enhanced CT scan shows free intraperitoneal air and contrast extravasation near the descending colon.Urgent exploratory laparotomy with bowel repair or resection
  • An 82-year-old male in the intensive care unit on high-dose vasopressors for severe pneumonia develops right upper quadrant pain; ultrasound shows a thickened gallbladder wall, pericholecystic fluid, and sludge without gallstones.Image-guided percutaneous cholecystostomy tube placement

Answer

The presentations map appropriately to subtotal colectomy for medically refractory toxic megacolon, laparoscopic appendectomy for acute appendicitis in early pregnancy, exploratory laparotomy for penetrating colonic trauma with free air, and percutaneous cholecystostomy for acalculous cholecystitis in a hemodynamically unstable patient.
Each correct pairing aligns a life-threatening abdominal pathology with its evidence-based definitive management. Toxic megacolon failing medical management demands an emergent subtotal colectomy. Uncomplicated appendicitis in early pregnancy requires a prompt laparoscopic appendectomy. Penetrating trauma causing a hollow viscus perforation (indicated by free air) necessitates an exploratory laparotomy. Finally, acalculous cholecystitis in an unstable patient unfit for surgery requires percutaneous cholecystostomy tube drainage.

Step-by-Step Solution

1
Evaluate the patient with medically refractory ulcerative colitis and massive colonic dilation.
The diagnosis is toxic megacolon unresponsive to steroids.
When medical therapy fails, immediate surgical intervention (subtotal colectomy) is required to prevent fatal colonic perforation.
2
Assess the pregnant patient with ultrasound-confirmed appendicitis.
The diagnosis is acute appendicitis in the first trimester.
Delaying surgery increases the risk of rupture and fetal loss; prompt laparoscopic appendectomy is the standard of care.
3
Analyze the trauma patient with a stab wound and free intraperitoneal air.
The diagnosis is penetrating abdominal trauma with bowel perforation.
Free air indicates a hollow viscus injury, which is an absolute indication for an immediate exploratory laparotomy.
4
Examine the critically ill ICU patient with gallbladder inflammation but no stones.
The diagnosis is acute acalculous cholecystitis.
Because the patient is on high-dose vasopressors and too unstable for a cholecystectomy, a percutaneous cholecystostomy tube must be placed for source control.
