Summary
This study shows that an endoscopic-assisted retroperitoneal approach is a safe and effective minimally invasive treatment for spondylodiscitis with psoas abscess, especially in high-risk patients.
Area of Science:
- Spinal Surgery
- Infectious Diseases
- Minimally Invasive Procedures
Background:
- Spondylodiscitis with psoas abscess is a severe spinal infection.
- Conventional surgery poses high risks for frail patients.
- Minimally invasive techniques are needed to reduce surgical trauma.
Purpose of the Study:
- To evaluate the efficacy and safety of an endoscopic-assisted retroperitoneal approach for spondylodiscitis with psoas abscess.
- To assess outcomes in high-risk patient populations.
Main Methods:
- Retrospective case series of 9 patients treated between 2013-2023.
- Data collected: demographics, comorbidities, operative details, pain scores, functional outcomes, and satisfaction.
- Follow-up included laboratory marker normalization and 6-month satisfaction scores.
Main Results:
- Mean operative time: 149.44 min; Mean blood loss: 88.89 mL.
- Significant postoperative pain reduction observed.
- 88.89% maintained or improved spinal injury scores; 77.78% reported good to excellent satisfaction at 6 months.
Conclusions:
- Endoscopic-assisted retroperitoneal approach is a feasible and promising treatment for spondylodiscitis with psoas abscess.
- This minimally invasive method offers reduced tissue damage and favorable recovery.
- It is particularly advantageous for frail patients with comorbidities.
