Difficulty: MediumPreoperative and Postoperative Care

A 68-year-old man is evaluated on postoperative day 5 following an exploratory laparotomy and colon resection for ischemic colitis. He has a medical history of obesity and severe chronic obstructive pulmonary disease. While being assisted out of bed by the nursing staff, he has a violent coughing fit and reports a sudden "tearing" sensation in his abdomen. His temperature is 37.2°C (99.0°F), blood pressure is 130/80 mm Hg, pulse is 98/min, and respirations are 18/min. Physical examination reveals that the lower half of the surgical incision has separated, and several loops of small bowel are visibly protruding through the fascial defect onto the abdominal wall. Arrange the following management steps in the most appropriate chronological order.

  1. 1Cover the exposed viscera with sterile, saline-moistened dressings.
  2. 2Place the patient in a supine position with the hips and knees flexed.
  3. 3Establish large-bore intravenous access and administer fluid resuscitation and antibiotics.
  4. 4Transfer the patient to the operating room for emergent fascial closure.

Answer

The correct chronological management of acute abdominal evisceration is to first cover the exposed viscera with sterile, saline-moistened dressings, followed by positioning the patient to reduce abdominal tension (hips and knees flexed). Next, the patient should be systematically prepared for surgery with intravenous fluids and broad-spectrum antibiotics, and finally transferred to the operating room for definitive surgical closure.
Acute abdominal evisceration is a surgical emergency. The immediate sequence of actions prioritizes protecting the bowel and preventing further evisceration, followed by systemic stabilization, and finally definitive surgical repair. First, the exposed bowel must be covered with sterile, saline-soaked dressings to prevent desiccation and contamination. Next, the patient should be placed supine with knees and hips flexed to relax the abdominal wall musculature, thereby reducing intra-abdominal pressure and preventing further bowel herniation. After securing the physical site, systemic preparation for surgery is initiated by establishing intravenous access for fluid resuscitation and administering broad-spectrum antibiotics to prevent infection. Finally, the patient is transferred to the operating room for exploratory laparotomy, reduction of the bowel, and secure fascial closure. Notably, bedside manual reduction of the bowel is strictly contraindicated.

Step-by-Step Solution

1
Cover the exposed viscera with sterile, saline-soaked dressings.
The bowel is protected from the external environment.
Immediate mechanical protection prevents irreversible ischemia, desiccation, and massive contamination.
2
Place the patient in a supine position with the hips and knees flexed.
Intra-abdominal pressure is reduced.
Flexing the hips and knees relaxes the rectus abdominis and oblique muscles, which prevents further loops of bowel from herniating through the fascial defect.
3
Establish large-bore intravenous access and administer fluid resuscitation and antibiotics.
Systemic stabilization and antimicrobial prophylaxis are achieved.
The patient must be hemodynamically optimized and pre-treated for potential peritonitis before undergoing an emergent return to the operating room.
4
Transfer the patient to the operating room for emergent fascial closure.
Definitive surgical repair is performed.
Evisceration requires formal surgical exploration, thorough irrigation, bowel reduction, and secure fascial closure under general anesthesia.
