Bilateral Endoscopic Debridement Combined with Local Antituberculosis Drugs for Thoracic Tuberculosis with Large Paravertebral Abscess: A Multicenter Study with 4-year Follow-Up.

Background: Paravertebral abscess represents a prevalent manifestation of thoracic tuberculosis, often necessitating surgical intervention. In this study, we introduced a novel approach by employing bilateral endoscopic debridement (BED) to address large Paravertebral abscesses associated with thoracic tuberculosis, a method not previously proposed in the literature. The clinical efficacy was examined through a comprehensive 4-year follow-up.
