Contribution of 3D Printing in Anatomical Lung Segmentectomies.

Contribution of 3D Printing in Anatomical Lung Segmentectomies: a Prospective Randomized Controlled Pilot Trial.

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.

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.

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.
