Zorluk: OrtaGastrointestinal and Abdominal Surgery

A 38-year-old woman is evaluated by the surgical team 24 hours after admission for a mechanical small bowel obstruction. Her initial management included intravenous fluid resuscitation, bowel rest, and nasogastric tube decompression. Over the last 3 hours, she has developed severe, constant abdominal pain that is distinctly different from the cramping pain she experienced on admission. She underwent a total abdominal hysterectomy for uterine fibroids 4 years ago. Her temperature is 38.8°C (101.8°F), blood pressure is 96/60 mmHg, pulse is 124/min, and respirations are 22/min. On physical examination, the abdomen is distended. There is marked right lower quadrant tenderness with guarding and rebound. The nasogastric tube has drained 400 mL of bilious fluid since placement. Laboratory results demonstrate a leukocyte count of 18,000/mm³ with 15% bands, and a serum lactate of 3.5 mmol/L. Which of the following is the most appropriate next step in management?

  1. Immediate exploratory laparotomyCevap
  2. B
    Computed tomography of the abdomen and pelvis with intravenous contrast
  3. C
    Continuation of conservative management with serial abdominal examinations
  4. D
    Diagnostic laparoscopy
  5. E
    Therapeutic colonoscopy with decompression

Cevap

Immediate exploratory laparotomy
The correct answer is immediate exploratory laparotomy. This patient's presentation is highly concerning for a strangulated small bowel obstruction (SBO), which is a surgical emergency. While uncomplicated SBO can be initially managed conservatively with bowel rest, intravenous fluids, and nasogastric tube decompression, signs of clinical deterioration dictate immediate operative intervention. This patient exhibits the classic findings indicating bowel ischemia or infarction: fever, tachycardia, hypotension, and severe continuous pain (as opposed to colicky pain). Furthermore, she has developed overt peritonitis (guarding and rebound tenderness), marked leukocytosis with bandemia, and an elevated lactate level, all of which strongly point to bowel necrosis. Immediate surgical exploration is required to resect any necrotic bowel and relieve the underlying obstruction.

Adım Adım Çözüm

1
Analyze the patient's history and initial presentation.
The patient has a mechanical small bowel obstruction initially managed conservatively.
Establishes the baseline diagnosis and management plan.
2
Evaluate the new clinical findings and vital signs.
The patient has developed continuous severe pain, fever, tachycardia, hypotension, and localized peritonitis, along with leukocytosis and elevated lactate.
Identifies the hallmark signs of clinical deterioration and bowel strangulation.
3
Determine the appropriate management for strangulated SBO.
The presence of peritonitis and suspected bowel ischemia necessitates immediate surgical intervention.
Delaying surgery for further imaging or continuing conservative management increases the risk of bowel perforation and mortality.

Anahtar Kavram

Indications for immediate surgical intervention in small bowel obstruction include signs of peritonitis, clinical deterioration (fever, continuous pain, hemodynamic instability), and laboratory evidence of ischemia (leukocytosis, elevated lactate).
