Match each patient's clinical presentation of an acute abdomen with the most appropriate next step in diagnosis or management.

  • A 65-year-old man with a history of atrial fibrillation presenting with sudden, severe abdominal pain that is out of proportion to his benign physical exam findings.CT angiography of the abdomen and pelvis
  • A 42-year-old woman presenting with right upper quadrant pain, high fever, jaundice, hypotension, and acute confusion.Emergent endoscopic retrograde cholangiopancreatography (ERCP)
  • A 24-year-old man presenting with acute right lower quadrant pain, diffuse abdominal rigidity, involuntary guarding, and severe rebound tenderness.Emergent exploratory laparotomy
  • A 55-year-old woman with a prior open appendectomy presenting with colicky abdominal pain, bilious emesis, obstipation, and a distended but non-tender abdomen.Nasogastric tube decompression and intravenous fluid resuscitation

Cevap

The patient with atrial fibrillation and pain out of proportion matches with CT angiography. The patient with Reynold's pentad matches with ERCP. The patient with diffuse peritonitis matches with emergent exploratory laparotomy. The patient with uncomplicated small bowel obstruction matches with nasogastric tube decompression.
The correct matches align classic acute abdominal syndromes with their gold-standard initial management steps. Mesenteric ischemia requires CT angiography to evaluate the mesenteric vessels. Severe cholangitis with shock requires emergent biliary decompression via ERCP. A rigid abdomen with peritonitis requires immediate surgical exploration. An uncomplicated small bowel obstruction requires conservative management with NGT decompression and IV fluids.

Adım Adım Çözüm

1
Analyze the first patient's presentation.
The combination of atrial fibrillation and severe pain out of proportion to a benign exam suggests acute mesenteric ischemia.
Atrial fibrillation predisposes patients to arterial emboli, and the lack of peritoneal signs early in the disease process is a hallmark of mesenteric ischemia.
2
Analyze the second patient's presentation.
The constellation of fever, right upper quadrant pain, jaundice, hypotension, and confusion diagnoses severe acute ascending cholangitis.
This is a life-threatening biliary infection that rapidly progresses to sepsis if not decompressed.
3
Analyze the third patient's presentation.
Diffuse rigidity, involuntary guarding, and rebound tenderness indicate a surgical abdomen with generalized peritonitis.
Peritonitis from a presumed perforated viscus is a surgical emergency.
4
Analyze the fourth patient's presentation.
Prior surgery, colicky pain, bilious vomiting, and distension without peritonitis suggest an uncomplicated small bowel obstruction (SBO).
Postoperative adhesions are the most common cause of SBO, and the absence of peritonitis indicates it is uncomplicated.
5
Determine the next appropriate step for each condition based on standard surgical guidelines.
Mesenteric ischemia requires CT angiography; severe cholangitis requires ERCP; generalized peritonitis requires exploratory laparotomy; uncomplicated SBO requires NGT decompression.
These steps represent the gold-standard initial triage and management for these specific surgical and gastrointestinal emergencies.
