Recently, the hospital has successfully performed retroperitoneal cluster ligation of varicocele for a number of patients with varicocele using needle laparoscopic technique, and obtained excellent clinical results. Varicocele is a tortuous expansion of the veins in the spermatic cord due to the obstruction of reflux, which refers to the dilatation, tortuosity and lengthening of the blood vessels in the spermatic trapezius plexus (venous vascular plexus) due to the stagnation of blood flow in the spermatic veins. It is a common disease in young adults, with a prevalence of 10-15% in the male population and 15-20% in male infertility. It occurs on the left side of the body, but bilateral varicose veins are not uncommon and can be present in up to 20% of cases. Varicocele, can lead to testicular atrophy and impaired spermatogenesis, and even male infertility. Varicocele can also be caused by renal tumors or other retroperitoneal tumors. Varicocele caused by compression is called symptomatic or secondary varicocele. Clinically, varicocele can be divided into three degrees: I degree (mild): when standing, you can’t see varicose veins protruding from the skin of the scrotum, but you can feel the varicose veins inside the scrotum, and the varicose veins disappear quickly when you lie down; II degree (moderate): when standing, you can see the dilated veins protruding from the scrotum, and you can feel the varicose veins inside the scrotum, and the bulge disappears gradually when you lie down; III degree (severe): There are obvious thick blood vessels on the surface of the scrotum, obvious earthworm-like dilated veins in the scrotum, and the wall of the veins is hypertrophied and hardened; it disappears slowly when lying down. The traditional treatment is mainly open surgery, and the operation styles are intra-scrotal spermatic vein ligation, inguinal spermatic vein ligation, spermatic vein ligation at the inner ring and retroperitoneal internal spermatic vein ligation. The first two of these procedures have a high recurrence rate and have been abandoned. Retroperitoneal internal spermatic vein ligation or cluster ligation has the best effect and the lowest recurrence rate because it achieves the highest ligation, but it is difficult to promote the traditional open surgery because of its high trauma; at present, high spermatic vein ligation at the inner ring is the commonly used procedure for open surgery. In recent years, patients with varicocele have also benefited from the popularization and application of laparoscopic technology. According to the surgeon, laparoscopy is thorough, minimally invasive, and quick to recover due to the magnified field of view and the ease of dissecting the retroperitoneal internal spermatic vein. We chose to poke holes in the lower edge of the umbilical fossa 5mm, suprapubic pubic hair area 5mm poke holes, two poke holes to achieve the minimum trauma of the needle laparoscopy, but also to achieve a completely hidden scar laparoscopic technology, and then under the observation of laparoscopy, separation of the intravesical spermatic vein to give the ligation of dissections. After surgery, the patient is awake enough to resume activities and can be discharged from the hospital on the next day after surgery.
