Difficulty: MediumGastrointestinal and Abdominal Surgery

Match each clinical presentation of an acute abdominal condition with its most appropriate initial definitive management step.

  • A 45-year-old patient with a history of open appendectomy presents with crampy abdominal pain and dilated small bowel loops, but has normal vital signs and a soft, non-peritonitic abdomen.Nasogastric tube decompression, intravenous fluid resuscitation, and serial clinical evaluations
  • A 68-year-old patient with prior pelvic surgery presents with obstipation, feculent emesis, and new-onset focal abdominal guarding, fever, and leukocytosis.Emergent exploratory laparotomy with adhesiolysis and evaluation of bowel viability
  • A 61-year-old patient experiences sudden, severe, diffuse abdominal pain, presenting with a rigid, board-like abdomen and subdiaphragmatic free air on upright radiograph.Emergent exploratory laparotomy with primary defect repair and omental patch closure
  • A 58-year-old patient presents with fever and progressive left lower quadrant pain; imaging demonstrates a 4.5-cm rim-enhancing fluid collection adjacent to the sigmoid colon.Percutaneous computed tomography-guided fluid drainage and intravenous antibiotics

Answer

The correct matches align the underlying surgical pathology to the standard of care: uncomplicated bowel obstruction to conservative management, strangulated obstruction to surgical adhesiolysis, perforated viscus to omental patch repair, and diverticular abscess to percutaneous drainage.
Each clinical scenario maps directly to its evidence-based surgical or interventional treatment guideline. Uncomplicated obstructions safely undergo a trial of non-operative management, whereas signs of strangulation or perforation mandate immediate laparotomy. Large localized abscesses in diverticulitis are drained percutaneously to minimize surgical morbidity.

Step-by-Step Solution

1
Evaluate the clinical status of the patient with a history of prior surgery and dilated bowel loops.
The absence of peritonitis or systemic toxicity indicates an uncomplicated small bowel obstruction.
Differentiating uncomplicated from complicated obstruction determines if conservative management is safe.
2
Assess the patient presenting with obstipation, feculent emesis, and focal guarding.
The presence of fever, leukocytosis, and localized peritonitis points to a strangulated small bowel obstruction.
Strangulation implies bowel ischemia, which is an absolute indication for emergent surgical exploration.
3
Identify the pathology causing a rigid abdomen and subdiaphragmatic free air.
These findings are classic for a perforated viscus, such as a peptic ulcer.
A perforated ulcer leaks gastrointestinal contents into the peritoneum, requiring immediate washout and omental patch repair.
4
Determine the management for a 4.5-cm pericolic fluid collection in the setting of left lower quadrant pain.
The fluid collection represents a diverticular abscess.
Abscesses larger than 3 cm are best managed initially with percutaneous drainage to resolve the acute infection and avoid urgent colostomy.
