Identifying pathogens of spondylodiscitis: percutaneous endoscopy or CT-guided biopsy.

ABSTRACT: Identifying offending pathogens is crucial for appropriate antibiotic administration for infectious spondylitis. Although computed tomography (CT)-guided biopsy for bacteriologic diagnosis is a standard procedure, it has a variable success rate. Some reports claim percutaneous endoscopic discectomy and drainage offer a sufficient amount of tissue for microbiologic examination and easy application. We therefore compared the diagnostic value of CT guidance with that of endoscope guidance in 52 patients with suspected infectious spondylitis. Twenty patients underwent percutaneous endoscopic discectomy and drainage by an orthopaedic surgeon and the other 32 patients underwent CT-guided biopsies by a radiologist. Patients were followed a minimum of 12 months after treatment. Culture results of the biopsy specimens were recorded. Causative bacteria were identified more frequently with percutaneous endoscopy than in CT-guided biopsy (18 of 20 [90%] versus 15 of 32 [47%]). We observed no biopsy-related complications or side effects in either group. The data suggest percutaneous endoscopic discectomy and drainage yield higher bacterial recovery rates than CT-guided spinal biopsy.Level III, therapeutic study.

Project description:BackgroundPneumothorax is a common complication induced by computed tomography (CT)-guided percutaneous needle biopsy, with a frequency of 17-40.4%. It remains debatable how to predict and prevent the occurrence of post-biopsy pneumothorax. In a real-world setting, we investigated the characteristics associated with pneumothorax in primary lung nodule biopsy.MethodsThis clinical registry cohort study recorded patients with newly diagnosed pulmonary nodules from 10 medical centers from April 2021 to April 2022, and the data were input into the electronic data capture (EDC) system. The eligibility criteria for participants included being within the age range of 18 to 80 years and expressing a willingness to undergo percutaneous puncture biopsy, among other requirements. Conversely, the exclusion criteria included an inability to cooperate throughout the biopsy process and the emergence of new health issues during the study duration resulting in attendance delays, among other factors. This study collected data from 924 patients, out of which 593 were included after exclusion. The essential characteristics, imaging features of pulmonary nodules, and technical factors associated with percutaneous biopsy were recorded. T-tests or one-way analysis of variance (ANOVA) were performed for continuous variables and Pearson's χ2 test, likelihood ratio, or Fisher's exact test were applied for categorical variables for comparison as appropriate, followed by multivariate logistic regression.ResultsThe overall incidence of pneumothorax was 13.0% (77/593), among which timely pneumothorax was 10.3% (61/593), delayed pneumothorax was 2.7% (16/593), and the rate of chest tube placement was 3.4% (20/593). There was no significant difference in the incidence of pneumothorax in a needle size range of 16-19 G (P=0.129), but the incidence of pneumothorax was lower with 17 G needles than with 18 G. An increased morbidity of pneumothorax was correlated with age (P=0.003), emphysema (P=0.006), and operation time (P=0.002). There was no significant increase in the incidence of pneumothorax between 1 or 2 passes through the pleura (P=0.062). However, multiple pleural passes (3 times) increased the chances of pneumothorax significantly (P=0.022). These risk factors have a certain clinical value in predicting the incidence of post-biopsy pneumothorax, and the area under the curve (AUC) was 0.749.ConclusionsThe most common post-biopsy complication, pneumothorax, was managed conservatively in most cases. A maximum of two pleural passes does not increase the incidence of pneumothorax, and the 17 G needle is more suitable for percutaneous biopsy of pulmonary nodules in the real world.
