Varicocele and male factor infertility treatment: a new meta-analysis and review of the role of varicocele repair.

OBJECTIVE

To present our initial experience in children undergoing single-port laparoscopic varicocelectomy (SPLV) using a new approach in which the entire procedure is performed through a multichannel single laparoscopic port inserted in the umbilicus rather than the traditional LV performed through three abdominal ports.



PATIENTS AND METHODS

We reviewed our experience with all paediatric patients who had undergone transumbilical SPLV [Uni-XTM Single Port Access Laparoscopic System, Pnavel Systems, NJ, USA]. This novel 20-mm laparoscopic port has three working channels and gas insufflation access. The system also includes a variety of curved laparoscopic instruments that can be introduced through the SP. A Hassan technique through an incision within the inferior aspect of the umbilicus is used to obtain laparoscopic port access to the abdominal cavity. The SP is then fixed into position with pre-placed rectus facial sutures. Using a curved laparoscopic grasper and scissors, an incision is made within the posterior peritoneum on the medial and lateral aspects of the left testicular artery and veins, proximal to the vas deferens. The vessels, both artery and veins, are transected leaving clips both proximally and distally.



RESULTS

Transumbilical SPLV was completed in three consecutive adolescents (aged 13, 15 and 16 years) without placing any additional ports or conversion to open surgery. All procedures were performed for left-sided grade III varicoceles. The operative duration was <1 h for each procedure. All patients were discharged on the same day as their surgery and none required re-hospitalization. At a mean (range) follow-up of 8.7 (6–10) weeks there was a good cosmetic result, with no varicocele recurrence, or intraoperative or postoperative complications including wound infection, hydrocele, or incision site herniation.



CONCLUSION

We report the first use of a multicannula single laparoscopic port in children and for SPLV. This new laparoscopic approach, similar to any new technique, requires further experience to fully evaluate its benefits and limitations.

Single‐port laparoscopic surgery: initial experience in children for varicocelectomy

Wound healing is a complex process of recovering the forms and functions of injured tissues. The process is tightly regulated by multiple growth factors and cytokines released at the wound site. Any alterations that disrupt the healing processes would worsen the tissue damage and prolong repair process. Various conditions may contribute to impaired wound healing, including infections, underlying diseases and medications. Numerous studies on the potential of natural products with anti-inflammatory, antioxidant, antibacterial and pro-collagen synthesis properties as wound healing agents have been performed. Their medicinal properties can be contributed by the content of bioactive phytochemical constituents such as alkaloids, essential oils, flavonoids, tannins, saponins, and phenolic compounds in the natural products. This review highlights the in vitro, in vivo and clinical studies on wound healing promotions by the selected natural products and the mechanisms involved.

Wound Healing Properties of Selected Natural Products.

Many facets of wound healing under redox control require a delicate balance between oxidative stress and antioxidants. While the normal physiology of wound healing depends on low levels of reactive oxygen species and oxidative stress, an overexposure to oxidative stress leads to impaired wound healing. Antioxidants are postulated to help control wound oxidative stress and thereby accelerate wound healing. Many antioxidants are available over the counter or by prescription, but only one, Medihoney®, has been specifically FDA approved for wound healing. Here we review the existing evidence for the use of antioxidants for wound healing, with a review of the pertinent animal and clinical studies. Natural products and naturally derived antioxidants are becoming more popular, and we specifically review the evidence for the use of naturally derived antioxidants in wound healing. Antioxidant therapy for wound healing is promising, but only few animal studies and even fewer clinical studies are available. Because only few products have undergone FDA approval, the consumer is advised to scrutinize them for purity and contaminants prior to use, and this may require direct contact with the companies that sell them. As a field of science, the use of antioxidants for wound healing is in its infancy, and future studies will better elucidate the role of antioxidants in wound healing.

Cutaneous scarring is often the epicenter of patient-related concerns, and the question "Will there be a scar?" is one that is all too familiar to the everyday clinician. In approaching this topic, we have reviewed the pathology, the embryology, and the molecular biology of cutaneous scarring.

The aim of this prospective study was to assess long-term functional results (spermiograms) in subjects who underwent laparoscopic varicocelectomy via either of 2 procedures (ligation or preservation of testicular artery). A total of 122 patients underwent laparoscopic varicocelectomy performed via either of the 2 different procedures: complete ligation of the spermatic vessels or preservation of the spermatic artery. After surgery when patients achieved 18 years, they were asked to undergo semen analysis. Spermiogram results were divided into 2 subgroups: "normal" and "abnormal." We analyzed volume, sperm count per mL, percentage of motile spermatozoa, percentage of normal spermatozoa, and percentage of vitality for each group. Both groups showed the same results in terms of "normal" and "abnormal" spermiograms (World Health Organization criteria), but analysis showed higher sperm concentration per mL, sperm motility, volume, vitality, and rate of morphologically normal sperm for the group with arteries preserved and "normal" spermiograms (P < .01). Analysis of data from the spermiograms showed that preservation of the testicular artery was the best possible option in terms of semen quality. Therefore, we believe that surgical treatment of varicocele should be carried out using procedures involving artery preservation.

Summary Background One of the main problems of elective surgery is the cosmetic result. Objective This prospective controlled study aims to determine the effects of topical vitamin E on cosmetic results in children. Methods A single-blind study was carried out. Topical vitamin E was used on the intended incision site for at least 15 days, thrice daily, before surgery and for at least 30 days, twice daily, after surgery (group A). The control group received topical petrolatum-based ointment (group B). Results No patients in group A developed keloids. A total of 96% of patients (or parents) considered the cosmetic results very good. No patients had wound infection. In the control group, only 78% of patients (or parents) considered the cosmetic results very good and 13 (6.5%) patients developed keloids after 6 months. There were no cases of wound infection. Conclusion Topical vitamin E before and after surgery improved surgical wound healing and improved cosmetic results.

Phimosis has been defined as unretractable foreskin without adherences and/or a circular band of tight prepuce preventing full retraction. The aim of this study is to evaluate the efficacy (response rate) of topical steroids for the treatment of tight phimosis at different age stages. After using the same medication with different dosage schemes, a retrospective analysis was carried out to assess the efficacy of topical steroids in the treatment of tight phimosis. Patients were divided into three groups: group A (betamethasone scheme A), group B (betamethasone scheme B) and group C (control group). Remission of phimosis, with a complete exposure and without a narrowing behind the glans, was considered a complete response to treatment. The outcomes were then related to dosage scheme and patient’s age. The dosage for group A was more effective than the dosage for groups B and C (control group). Phimosis resolved in 90% (group A), 72% (group B) and 56% (group C) of cases. A successful treatment was closely related to the age of patients at the beginning of steroid application. The results showed that treatment with topical steroids, which in general gives good results, proved to be much more successful in patients aged between 4 and 8 years, suggesting the efficacy of an early beginning of the treatment.

The development of testicular hypotrophy (or testicular growth arrest) in pediatric patients with varicocele is the first indication for surgery. The aim of this study is to identify the correlation between grade of varicocele, grade of vein reflux and testicular growth arrest. Between 2000 and 2001, we recruited 226 patients affected by varicocele without testicular hypotrophy and with grades 2–3 spermatic vein reflux observed during Doppler velocimetry. Medical examinations carried out every 6 months allowed the assessment of varicocele grade, testicular volume, and grade of vein reflux. Other parameters considered in the study were: mean time of grade deterioration, mean time to onset of testicular growth arrest and the relationship between varicocele grade and testicular growth arrest. Deterioration of the condition was experienced in 92 patients (40%) in which 60 patients showed higher varicocele grades without testicular growth arrest, while 32 patients developed testicular growth arrest. There was a statistically significant relationship between testicular growth arrest and varicocele grades (grade 2 and 3) and between grade of reflux and testicular growth arrest. Although it is not possible to determine which patients will develop testicular growth arrest, the assessment of vein reflux allows the identification of those subjects who may potentially develop such a condition.
