Evaluation of a knotless barbed suture for canine total lung lobectomy: An ex vivo study.

ABSTRACT:

Objective

To compare leakage pressure and ligation time of bronchial sealing using barbed sutures, stapling devices, or traditional sutures during total lung lobectomy in dogs.

Study design

Experimental ex vivo study with randomized order of procedures.

Sample population

A total of 30 lung lobes from five canine cadavers weighing 10-13 kg.

Methods

The lobe samples were randomly allocated to the stapling device (ST), traditional suture ligation (TR), or barbed suture ligation (BA) group (n = 10 each). Bronchial ligation time was recorded for each procedure. Each bronchial stump was tested for air leakage for pressures up to 80 cmH₂O.

Results

The median air leakage pressure was 45.0 cmH₂O (range: 30.0-80.0) for the ST, 47.5 cmH_2<
