(1) Because a small incision can be used to perform bilateral spermatic vein ligation at the same time, no additional incision is needed, saving time, no incision, small trauma, and no postoperative wound stitches; (2) The laparoscope has a magnifying effect and a clear view (the mirror can magnify the spermatic vein 8 times), which is conducive to thoroughly distinguishing the spermatic vessels and preventing testicular atrophy caused by mistakenly tying the testicular artery; (3) The postoperative The advantages such as quick recovery are gradually accepted by the majority of patients. (4) Due to the high position of the ligation, the vas deferens and the arteries and veins will not be damaged. (5) In case of recurrence of varicocele after open surgery, it is difficult to operate again because of the adhesions at the original incision, and the effect is not good, and among the recurrence after open surgery, the proportion of patients with bilateral varicocele is larger; while laparoscopic high ligation of the spermatic cord can be performed without the adhesions at the original incision, and high ligation can be performed above the adhesions, which is also less traumatic, effective and has a low recurrence rate. Laparoscopic high ligation of the internal spermatic vein should be the preferred procedure in hospitals that have the conditions. (6) Other lesions in the abdominal cavity, such as uterine adnexa, large and small intestine and other organs in the pelvic area, can also be investigated through this laparoscopic surgery.
