简要总结

Pneumothorax is the most common complication after CT-guided lung biopsy, and several techniques have been proposed to reduce the risk. Among them, rapid rollover is the maneuver to immediately reposition the patient, with biopsy-side down after removal of biopsy needle. It has been theorized that the technique reduces the size of alveoli surrounding the needle tract, leading to airway closure and reduction in the alveolar-to-pleural pressure gradient, thereby preventing pneumothorax. The aim of this study is to evaluate the effectiveness of rapid rollover in reducing the risk of radiographically detectable pneumothorax and the rate of chest tube insertion.

Patients undergoing CT-guided lung biopsy for any indication will be recruited and randomized into either rapid rollover group or control group. In the control group, CT guided lung biopsy will be performed per standard protocols; in the rapid rollover group, the biopsy will also be performed per the same protocol with the addition of rapid rollover at the end of the procedure. For both groups, the primary outcome would be new or enlarging pneumothorax detected on post-biopsy radiographs, and the secondary outcome would be the risk of pneumothorax necessitating chest tube insertion, all complications associated with CT guided lung biopsy, time to complication development, and patient experience in each arm.

详细描述

All patients will undergo CT-guided lung biopsy by the best approach decided by the primary operator. Randomization will be performed based on parity of patients' medical record numbers, which were assigned randomly at their first presentation. Patients with even medical record numbers will be assigned to the control group and patients with odd medical record number will be assigned to the intervention group.

In the rapid rollover group, patients will be repositioned upon being transferred from the CT scanner table to the stretcher such that the biopsy site is down. Patient in the intervention arm will be maintained in the same position in the post-procedure recovery area for at least 2 hours if patients can tolerate. Anyone who maintains the biopsy-site down position for at least 30 minutes after repositioning in the intervention group will be considered as completion of the intervention. Patients who are in the controlled arm may choose the most comfortable position per their preferences. All patients will be monitored for at least 2 hours, after which a 0-1 hour optional post-biopsy radiograph and 2-hour follow-up radiograph will be obtained to assess for pneumothorax per the standard current protocol. Further follow-up radiograph may be obtained if the patient did not receive the 0-1 hour radiograph and the 2-hour radiograph was positive for pneumothorax that is not large enough to require immediate chest tube insertion. Interpreting radiologists of the post-biopsy radiographs will be blinded to whether the patient is in the control or intervention group.

A survey will be given to the patients in post-anesthesia care unit by nurses before they are discharged.

Multiple patient-, lesion- and technique-specific factors will be recorded:

入选标准

  • All patients who are referred to the Department of Radiology and Biomedical Imaging Cardiac and Pulmonary Imaging section for CT-guided lung biopsy will be screened for eligibility. All eligible patients will be enrolled. Patients who develop intra-procedural pneumothorax will be analyzed but excluded from the final analysis.

排除标准

  • Patients with chest wall, subpleural or mediastinal lesions
  • Patients who develop intra-procedural pneumothorax
  • Patients who are biopsied by a prone approach
  • Patients who are repositioned intra-procedurally
  • Patients who are unable to tolerate reposition or have spinal precautions
  • Patients who develop hemothorax and a chest tube is inserted for this indication

结局指标

主要结局

Radiographically detectable pneumothorax

时间窗: 2 hours after biopsy

New or enlarging pneumothorax (from intraprocedural CT) which is detectable on post biopsy radiograph. The size of the pneumothorax will be measured in terms of the distance between visceral and parietal pleura. The severity of pneumothorax will be assessed using CTCAE 5.0.

次要结局

  • Chest tube insertion(24 hours for overnight observation)
  • Enlarging pneumothorax(From 2 hours post biopsy to patient being discharged home.)
