Difficulty: MediumGynecologic Procedures and Complications

A 35-year-old nulliparous woman is brought to the emergency department 5 days after undergoing an uncomplicated laparoscopic left ovarian cystectomy with fulguration of pelvic endometriosis. For the past 24 hours, she has experienced progressive, severe generalized abdominal pain accompanied by nausea and multiple episodes of emesis. Her temperature is 39.2°C (102.6°F), blood pressure is 86/54 mm Hg, and pulse is 128/min. She appears toxic and diaphoretic. Physical examination reveals a rigid, significantly distended abdomen with diffuse rebound tenderness and involuntary guarding. Bowel sounds are absent. Laboratory studies show a leukocyte count of 22,000/mm³ with a marked left shift. Which of the following is the most appropriate next step in management?

  1. Immediate exploratory laparotomyAnswer
  2. B
    Cross-sectional imaging of the abdomen and pelvis
  3. C
    Nasogastric tube decompression and serial abdominal examinations
  4. D
    Administration of intravenous antibiotics and clinical observation
  5. E
    Chest radiography and incentive spirometry

Answer

Immediate exploratory laparotomy is required to address the intra-abdominal catastrophe.
The correct answer is immediate exploratory laparotomy. This patient is presenting with septic shock and an acute surgical abdomen 5 days after a laparoscopic procedure involving electrosurgery (fulguration). This clinical picture is highly characteristic of a delayed thermal bowel injury. Unrecognized thermal energy transfer during laparoscopy can cause localized tissue necrosis that progresses over several days, eventually leading to full-thickness bowel perforation. This typically manifests between postoperative days 4 and 10. The resulting spillage of enteric contents causes diffuse peritonitis and sepsis. In a hemodynamically unstable patient with clear signs of peritonitis, immediate surgical exploration is required for source control, washout, and bowel repair or resection.

Step-by-Step Solution

1
Analyze the patient's postoperative timeline and symptoms
The patient developed severe abdominal pain, nausea, and vomiting 5 days after a laparoscopic procedure involving electrosurgery.
To identify the onset of the complication relative to the surgical intervention, which points toward delayed presentations like thermal injury.
2
Evaluate the vital signs and physical examination findings
Findings indicate septic shock (hypotension, tachycardia, fever) and peritonitis (rigid abdomen, rebound tenderness).
To determine the patient's hemodynamic stability and the urgency of the clinical situation.
3
Synthesize the clinical picture to establish the most likely diagnosis
The combination of findings strongly suggests a delayed thermal bowel injury leading to full-thickness perforation and enteric spillage.
Unrecognized thermal damage during fulguration undergoes progressive necrosis, typically perforating between postoperative days 4 and 10.
4
Determine the most appropriate next step in management
Immediate exploratory laparotomy must be performed.
Hemodynamically unstable patients with an acute surgical abdomen require emergent surgical exploration for washout and source control.

Key Concept

Unrecognized thermal bowel injury during laparoscopy typically presents on postoperative days 4-10 with peritonitis and sepsis; hemodynamically unstable patients require immediate exploratory laparotomy.
