Posterior Approach for Debridement of the Psoas Abscess
Published on: March 2, 2020
Psoas abscess. A rare complication of Crohn's disease
Abstract:
Psoas abscess complicating Crohn's disease is a rare condition. Fever, abdominal tenderness, limb pain and hip contracture are typical signs but only present in half of the cases. Cultures of the pus mostly grow a mixture of enterobacteria. The diagnosis is made by CT-scan. Medical therapy always results in recurrence of the abscess. Resection of the fistula and the affected bowel segment with end-to-end anastomosis is the therapy of choice. A case report is presented, followed by a review of the literature.
Insights
Psoas abscesses are rare in Crohn's disease, often presenting with non-specific symptoms. Surgical resection of affected bowel and fistulas offers the best outcome, avoiding recurrence common with medical management.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Surgical Oncology
Background:
- Psoas abscess is a rare complication of Crohn's disease.
- Typical signs like fever and abdominal pain are often absent.
- Enterobacteria are common in pus cultures.
Observation:
- Diagnosis relies heavily on CT scans.
- Medical therapy frequently leads to abscess recurrence.
- Surgical intervention is the preferred treatment.
Findings:
- Resection of the fistula and affected bowel segment is curative.
- End-to-end anastomosis is the recommended surgical technique.
- This approach minimizes recurrence rates.
Implications:
- Highlights the importance of considering psoas abscess in Crohn's patients with vague symptoms.
- Emphasizes surgical management over medical therapy for definitive treatment.
- Provides a basis for improved clinical guidelines and patient outcomes.
