About

The aim of the present work was to evaluate if the presence on the operating field of a 3D printed personalized model of the pulmonary anatomy of a patient operated by full thoracoscopy for an anatomical segmentectomy, makes it possible to reduce the mental workload and the fatigue of the surgeon.

Full description

Between 28.10.2020 and 05.10.2021, we successively included all anatomic segmentectomies performed by full thoracoscopy in our department, except for S6 segmentectomies, S4+5 left bisegmentectomy and patients for whom the time to surgery was considered too short to obtain the 3D printed model before surgery.

We performed a prospective randomized controlled pilot trial on 2 parallel arms:

• The "Digital" arm
• The "Digital+Object" arm.

Enrollment: 34 patients

Sex: All

Volunteers: No Healthy Volunteers

Inclusion criteria

• all anatomic segmentectomies performed by full thoracoscopy, except for S6 segmentectomies, S4+5 left bisegmentectomy and patients for whom the time to surgery was considered too short to obtain the 3D printed model before surgery.

Exclusion criteria

• S6 segmentectomies
• S4+5 left bisegmentectomy
• Patients for whom the time to surgery was considered too short to obtain the 3D printed model before surgery.

Trial design

34 participants in 2 patient groups

The "Digital" arm

Description:

Surgeons had a virtual 3D reconstruction of the patient's pulmonary anatomy by the Visible Patient Planning (VP) software

Treatment:

Procedure: Segmentectomy

The "Digital+Object" arm

Description:

Surgeons had at their disposal on the operating field, in a transparent sterile bag, the 3D printed model, made from the virtual 3D VP software of the patient's lung anatomy

Treatment:

Procedure: Segmentectomy
