Abstract
Double-armed suture longitudinal intussusception vasoepididymostomy (DA-LIVE) has been widely adopted owing to its simplicity and high success rate; however, specialized double-armed microsutures are required. To provide a novel single-armed suture longitudinal intussusception vasoepididymostomy (SA-LIVE) technique using only two single-armed sutures, named Guo's SA-LIVE. Four weeks after vasectomy in male adult Wistar rats, vasoepididymostomies were performed using DA-LIVE, SA-LIVE, or Guo's SA-LIVE. After 12weeks, functional patency was functionally assessed by evaluating for motile spermatozoa distal to the anastomosis. If no motile spermatozoa were visible, the mechanical patency of the anastomosis was tested by the ability of methylene blue to pass through the surgical anastomosis. The key procedure in Guo's SA-LIVE was cutting each needle with over 1cm attaching suture and making a flat overhand bend knot to tie the needle to the other end of the suture, after the needles were passed through the epididymal tubule and then the vasal lumen in an inside-out fashion, and then, the needles were passed through the vasal lumen in an inside-out fashion. The proportions of functional patency were 50.0% (3/6), 33.3% (2/6), and 50% (3/6) for the DA-LIVE, SA-LIVE, and Guo's SA-LIVE groups, respectively (P=.799). The proportions of mechanical plus functional patency for the three methods were 83.3% (5/6), 66.7% (4/6), and 83.3% (5/6), respectively (P=.725). The mean anastomosis times for the three LIVE techniques and the proportions of complications were similar (P=.150 and .758, respectively). Guo's single-armed suture technique is a potentially effective alternative to perform vasoepididymostomy when specialized double-armed microsutures are not available based on the current animal experiment.
