Input: Two randomized controlled trials evaluated the no-scalpel technique and differed in their findings. The larger trial demonstrated less perioperative bleeding (OR 0.49; 95% CI 0.27 to 0.89) and pain during surgery (OR 0.75; 95% CI 0.61 to 0.93), scrotal pain (OR 0.63; 95% 0.50 to 0.80), and incisional infection (OR 0.21; 95% CI 0.06 to 0.78) during follow up than the standard incisional group. Both studies found less hematoma with the no-scalpel technique (OR 0.23; 95% CI 0.15 to 0.36). Operations using the no-scalpel approach were faster and had a quicker resumption of sexual activity. The smaller study did not find these differences; however, the study could have failed to detect differences due to a small sample size as well as a high loss to follow up. Neither trial found differences in vasectomy effectiveness between the two approaches to the vas. The no-scalpel approach to the vas resulted in less bleeding, hematoma, infection, and pain as well as a shorter operation time than the traditional incision technique. No difference in effectiveness was found between the two approaches.
Output:

In February 2014, we did a computer search for studies comparing the no-scalpel approach to the vas with the scalpel method. We included randomized controlled trials in any language. For the initial review, we also looked at reference lists of articles and book chapters. We found two trials that looked at the no-scalpel approach to the vas. The trials had somewhat different results. The larger trial showed the no-scalpel method led to less bleeding, infection, and pain during and after the procedure. The no-scalpel approach required less time for the operation and had a faster return to sexual activity. The smaller study did not show these differences. However, the study may have been too small and many men dropped out. The two methods did not differ in the numbers of men who became sterile.
