Zorluk: KolayGastrointestinal and Abdominal Surgery

A 45-year-old man presents to the triage desk of the emergency department complaining of severe, unremitting abdominal pain that began 12 hours ago. He has had three episodes of bilious vomiting and reports passing no flatus since the pain started. His surgical history is notable for an open appendectomy performed 10 years ago. On initial assessment, his temperature is 38.9°C (102.0°F), pulse is 125/min, and blood pressure is 88/58 mmHg. Physical examination reveals a markedly distended abdomen. Palpation elicits diffuse rigidity, significant rebound tenderness, and involuntary guarding across all quadrants. Laboratory analysis demonstrates a leukocyte count of 19,000/mm³ with 85% neutrophils, and an elevated serum lactate level. Which of the following is the most appropriate next step in the management of this patient?

  1. Urgent operative explorationCevap
  2. B
    Placement of a nasoenteric decompression tube and serial abdominal examinations
  3. C
    Cross-sectional imaging of the abdomen and pelvis with intravenous contrast
  4. D
    Administration of broad-spectrum intravenous antibiotics and clinical observation
  5. E
    Noninvasive measurement of serial serum lactate and arterial blood gases

Cevap

Urgent operative exploration
The correct action is urgent operative exploration. This patient presents with a classic adhesive small bowel obstruction that has definitively progressed to strangulation or perforation, evidenced by fever, tachycardia, hypotension, elevated lactate, and most importantly, a rigid abdomen with diffuse peritonitis. In the presence of these undeniable 'red flag' surgical signs, the standard of care dictates aggressive fluid resuscitation paired with immediate exploratory laparotomy. Delaying source control for further diagnostic studies like CT imaging or attempting a trial of conservative decompression drastically increases the patient's risk of mortality.

Adım Adım Çözüm

1
Identify the primary clinical syndrome from the patient's presentation.
The patient has signs of a small bowel obstruction (colicky pain progressing to constant pain, bilious vomiting, obstipation, distension) in the context of prior abdominal surgery.
Prior surgical history is the leading risk factor for adhesive small bowel obstruction, guiding the differential diagnosis.
2
Assess the clinical findings for signs of complicated disease, such as ischemia, strangulation, or perforation.
The patient exhibits fever, tachycardia, hypotension, a rigid abdomen with diffuse peritonitis, significant leukocytosis, and an elevated lactate level.
These specific red-flag findings indicate that the obstruction has compromised bowel perfusion, leading to necrosis and potentially systemic sepsis.
3
Determine the most appropriate initial management based on the patient's hemodynamic status and physical examination.
Because the patient presents with a definitive 'surgical abdomen' (peritonitis) combined with hemodynamic instability, emergent laparotomy is required.
Any delay for imaging or conservative observation drastically increases mortality in the setting of a strangulated or perforated viscus.

Anahtar Kavram

Patients presenting with a clinical picture of small bowel obstruction who subsequently develop signs of peritonitis, hemodynamic instability, or bowel ischemia (e.g., fever, marked leukocytosis, elevated lactate) require immediate surgical exploration rather than conservative management or further diagnostic imaging.
