Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Area of Science:

Thoracic surgery
Surgical oncology
Diagnostic imaging

Background:

Thoracoscopic segmentectomy is standard for small peripheral pulmonary nodules.
Preoperative imaging influences surgical planning and outcomes.

Purpose of the Study:

To compare the efficacy of preoperative three-dimensional (3D) reconstruction computed tomography (CT) versus standard chest CT in thoracoscopic segmentectomy for small peripheral pulmonary nodules.
To assess the impact on operative time and perioperative outcomes.

Main Methods:

A multicentre randomized controlled trial (DRIVATS study) involving 191 patients.
Patients randomized to 3D reconstruction CT or standard chest CT prior to thoracoscopic segmentectomy.
Primary endpoint: operative time; Secondary endpoints: postoperative complications, blood loss, operative accidents.

Main Results:

No significant difference in operative time between the 3D reconstruction CT group (100 min) and standard chest CT group (100 min).
Similar incidence of postoperative complications and other perioperative outcomes between the two groups.
Only one intraoperative complication occurred in the standard chest CT group.

Conclusions:

Preoperative 3D reconstruction CT is feasible for thoracoscopic segmentectomy in patients with small peripheral pulmonary nodules.
3D reconstruction CT did not offer significant advantages in reducing operative time or improving perioperative outcomes compared to standard chest CT.
