Ex vivo comparison of single-layer and double-layer laparoscopic closure of equine bladders with 2 types of barbed sutures.

Objective: To compare laparoscopic single-layer versus double-layer closure of experimental, full-thickness incisions in adult equine urinary bladders using unidirectional and bidirectional barbed suture.

Study Design: Experimental, ex vivo, surgical study.

Sample Population: Thirty adult equine cadaver urinary bladders.
