Match each patient's clinical presentation with the most likely underlying postoperative or gastrointestinal complication.

  • A 62-year-old male on post-operative day 3 following an elective sigmoid resection. He has nausea, no passage of flatus, and generalized tympany. Abdominal radiography reveals dilated loops of both small and large bowel without a discrete transition zone.Postoperative ileus
  • A 78-year-old male recovering in the intensive care unit on day 4 following a coronary artery bypass graft. He develops massive, painless abdominal distension. Radiography reveals a cecal diameter of 11 cm with a normal-caliber small bowel and no mechanical obstruction.Acute colonic pseudo-obstruction (Ogilvie syndrome)
  • A 55-year-old female on post-operative day 6 after a left hemicolectomy. She suddenly develops severe, diffuse abdominal pain, a temperature of 39.2°C (102.5°F), tachycardia, and board-like abdominal rigidity.Anastomotic leak
  • A 45-year-old male presenting to the emergency department 8 months after an exploratory laparotomy for trauma. He reports severe, intermittent, cramping abdominal pain and bilious vomiting. Examination reveals hyperactive, high-pitched bowel sounds.Adhesive small bowel obstruction

Cevap

The patient with diffuse bowel dilation without a transition point has postoperative ileus; the ICU patient with isolated massive cecal dilation has acute colonic pseudo-obstruction (Ogilvie syndrome); the post-colectomy patient with sudden peritonitis has an anastomotic leak; and the patient with prior laparotomy and colicky pain has an adhesive small bowel obstruction.
Each presentation highlights a distinct gastrointestinal complication. Postoperative ileus involves diffuse functional dysmotility. Ogilvie syndrome features isolated massive colonic dilation in critically ill patients. Anastomotic leak presents with acute peritonitis and sepsis days after bowel anastomosis. Adhesive small bowel obstruction presents with mechanical blockage symptoms months to years after laparotomy.

Adım Adım Çözüm

1
Analyze the patient's surgical history and the timing of symptom onset.
Identified whether the presentation is acute (days post-op) or delayed (months to years later).
Complications like anastomotic leaks and ileus occur within days of surgery, whereas adhesive obstructions typically present months to years later.
2
Evaluate the physical exam findings.
Differentiated between functional dysmotility (absent or hypoactive bowel sounds), mechanical blockage (hyperactive or high-pitched sounds), and peritonitis (rigidity, fever).
Physical exam findings narrow down the differential between inflammatory/infectious causes and obstructive causes.
3
Correlate with abdominal imaging results.
Confirmed the specific pattern of bowel dilation.
Diffuse dilation implies ileus, isolated marked colonic dilation implies Ogilvie syndrome, and a discrete transition zone implies a mechanical obstruction.
