Intraoperative ultrasonography in thoracic surgery shows high sensitivity for locating lung tumors and assessing mediastinal structures. This technique may reduce the need for exploratory thoracotomies, improving surgical planning.

Area of Science:

  • Thoracic Surgery
  • Medical Imaging
  • Diagnostic Ultrasound

Background:

  • Intraoperative sonography is underutilized in thoracic surgery compared to other fields.
  • Limited maneuverability of sonographic probes hinders intrathoracic application.

Purpose of the Study:

  • To evaluate the efficacy of intrathoracic, intraoperative ultrasonography in thoracic surgery.
  • To assess the utility of a novel, electrically controllable sonographic probe handle.

Main Methods:

  • Intrathoracic ultrasound examinations were performed on 85 patients during thoracoscopy or open thoracic surgery.
  • A new electrically controllable probe handle was developed to enhance maneuverability.
  • Ultrasound was used for tumor localization, operability assessment, and lymph node/mediastinal tumor evaluation.

Main Results:

  • Thoracoscopic ultrasonography demonstrated high sensitivity in localizing intrapulmonary tumors.
  • Ultrasound effectively distinguished non-infiltrating tumors from vascular structures.
  • Assessment of operability for central tumors and visualization of mediastinal lymph nodes and tumors were successful.

Conclusions:

  • Intrathoracic ultrasonography is a valuable tool in thoracic surgery, particularly for tumor localization and mediastinal staging.
  • Further validation may lead to the replacement of some exploratory thoracotomies with thoracoscopic interventions.
  • Improved probe maneuverability enhances the clinical applicability of intraoperative ultrasound in the thorax.
