A 62-year-old man presents to the emergency department with a 3-day history of progressively worsening left lower quadrant abdominal pain, subjective fevers, and nausea. He has a history of diet-controlled type 2 diabetes and hypertension. His temperature is (), blood pressure is , pulse is , and respirations are . Physical examination demonstrates marked tenderness to palpation in the left lower quadrant with localized guarding, but no diffuse rigidity or generalized rebound tenderness. Bowel sounds are hypoactive. Laboratory results show a leukocyte count of with a left shift.
Arrange the following management steps in the most appropriate chronological order for this patient's anticipated clinical course.
- 1Initiate intravenous fluid resuscitation and broad-spectrum intravenous antibiotics.
- 2Obtain a computed tomography (CT) scan of the abdomen and pelvis with intravenous contrast.
- 3Perform image-guided percutaneous catheter drainage.
- 4Schedule an elective interval sigmoid colectomy.
Cevap
The correct chronological sequence begins with medical stabilization using intravenous fluids and antibiotics, followed by a diagnostic CT scan of the abdomen and pelvis. Upon identification of a large abscess, source control is achieved via percutaneous catheter drainage. Finally, an elective interval sigmoid colectomy is performed 6 to 8 weeks later.
The standard of care for a patient presenting with symptoms of acute complicated diverticulitis relies on a strict algorithmic approach. Immediate priorities are the ABCs, IV fluid resuscitation, and empiric broad-spectrum antibiotics to manage potential sepsis. Once initial stabilization is complete, a contrast-enhanced CT of the abdomen and pelvis is required to visualize any complications. For a Hinchey II presentation (a large pelvic or pericolic abscess, typically defined as >3 to 4 cm), image-guided percutaneous drainage is indicated. This achieves crucial source control while avoiding the severe morbidity of acute surgery in a highly inflamed operative field. After the inflammation subsides (usually 6 to 8 weeks later), the patient undergoes an elective interval sigmoid colectomy to prevent recurrence. The delayed timeline allows the surgeon to perform a primary anastomosis rather than a diverting colostomy.

Anahtar Kavram
The sequential management of complicated diverticulitis with a large abscess (Hinchey stage II) prioritizes immediate medical stabilization, CT diagnosis, minimally invasive source control via percutaneous drainage, and delayed definitive surgical resection.
