No. All vasectomies involve removing a segment and then closing both ends of the vas defens tube. Whether the vasectomy was no needle, no scalpel, or whether the ends were closed with suture, electrocautery, or staples it doesn’t matter.  What is seen at the time of the reversal is a scarred area of vas between the testicle and body side of the tube. This segment is removed, the ends resected to clean and pristine tissue and then prepared for the rejoining process. The operative microscope is useful in examining the “freshened” ends of the vas tubes as success rates depend on no residual scar at the point of the repair.
