Zorluk: KolayGastrointestinal and Abdominal Surgery

A 62-year-old man is brought to the emergency department complaining of severe abdominal pain. He reports a two-day history of crampy abdominal discomfort, accompanied by multiple episodes of bilious emesis and an inability to pass flatus. His surgical history is significant for an open appendectomy at age 25. Earlier today, the pain acutely transitioned from intermittent cramps to a constant, sharp pain. His temperature is 38.8°C (101.8°F), blood pressure is 92/60 mmHg, and heart rate is 122/min. On physical examination, the abdomen is distended, rigid, and exhibits diffuse rebound tenderness and involuntary guarding. Which of the following is the most appropriate next step in the management of this patient?

  1. A
    Cross-sectional imaging of the abdomen with intravenous contrast
  2. B
    Intravenous administration of broad-spectrum antimicrobial agents and clinical reassessment
  3. C
    Diagnostic laparoscopy at the bedside
  4. D
    Insertion of a gastrointestinal decompression tube and fluid resuscitation
  5. Urgent operative interventionCevap

Cevap

Urgent operative intervention
This patient presents with a classic history for a small bowel obstruction, likely secondary to adhesions from his previous appendectomy. However, the acute change to severe, constant pain, combined with fever, hemodynamic instability (hypotension, tachycardia), and peritonitis (rigidity, rebound tenderness), strongly suggests bowel ischemia, necrosis, or perforation. The presence of peritonitis in the setting of an obstruction is an absolute indication for immediate surgical exploration. Delaying surgery for further imaging or attempting nonoperative management significantly increases mortality.

Adım Adım Çözüm

1
Identify the primary clinical syndrome based on the patient's history.
The patient has a history of prior abdominal surgery, crampy abdominal pain, bilious emesis, and obstipation, which is highly consistent with a mechanical small bowel obstruction (SBO) secondary to adhesions.
Establishing the baseline diagnosis is necessary to evaluate the significance of acute changes in the patient's presentation.
2
Evaluate vital signs and physical examination findings for signs of complications.
The patient exhibits fever, tachycardia, hypotension, and a rigid abdomen with diffuse rebound tenderness.
These findings are red flags that differentiate a simple obstruction from a complicated one.
3
Synthesize the findings to determine the pathophysiologic state.
The transition to constant severe pain combined with peritonitis and hemodynamic instability indicates that the bowel has become ischemic, necrotic, or perforated (strangulated SBO).
Strangulation represents a life-threatening surgical emergency.
4
Select the definitive management step based on the established clinical state.
The patient requires immediate surgical exploration to resect ischemic bowel and restore continuity.
Conservative management or delaying for advanced imaging is contraindicated when overt peritonitis is present.
