Abstract

Varicocele is one of the most common causes of male infertility. Treatment options for varicoceles includes open varicocelectomy performed at various anatomical levels. Laparoscopic varicocelectomy has been established to be a safe and effective treatment for varicoceles. Robotic surgery has been introduced recently as an alternative surgical option for varicocelectomy. Microsurgical varicocelectomy has gained increasing popularity among experts in male reproductive medicine as the treatment of choice for varicocele because of its superior surgical outcomes. There is a growing volume of literature in the recent years on minimal invasive varicocele treatment with percutaneous retrograde and anterograde venous embolization/sclerotherapy. In this review, we will discuss the advantages and limitations associated with each treatment modality for varicoceles. Employment of these advanced techniques of varicocelectomy can provide a safe and effective approach aiming to eliminate varicocele, preserve testicular function and, in a substantial number of men, increase semen quality and the likelihood of pregnancy.

Treatment of palpable varicocele in infertile men: a meta-analysis to define the best technique.

Selahittin Çayan, Shavkat Shavakhabov, Ates Kadioglu (2015)

To date, there have been no randomized, controlled, prospective clinical studies that compare various techniques to describe the best method for the treatment of varicocele in infertile men. This meta-analysis aims to address the best treatment modality for palpable varicocele in infertile men. A MEDLINE search was performed for articles published between January 1980 and April 2008, and we analyzed 36 studies reporting postoperative spontaneous pregnancy rates and/or complication rates after varicocele repair using various techniques in infertile men with palpable unilateral or bilateral varicocele. Spontaneous pregnancy rates and postoperative complications such as hydrocele formation, recurrence, or persistence were compared among the techniques. In addition, interventional failure with radiologic embolization and reported complications with the laparoscopic approach were reviewed. Overall spontaneous pregnancy rates were 37.69% in the Palomo technique series, 41.97% in the microsurgical varicocelectomy techniques, 30.07% in the laparoscopic varicocelectomy techniques, 33.2% in the radiologic embolization, and 36% in the macroscopic inguinal (Ivanissevich) varicocelectomy series, revealing significant differences among the techniques (P = .001). Overall recurrence rates were 14.97% in the Palomo technique series, 1.05% in the microsurgical varicocelectomy techniques, 4.3% in the laparoscopic varicocelectomy techniques, 12.7% in the radiologic embolization, and 2.63% in the macroscopic inguinal (Ivanissevich) or subinguinal varicocelectomy series, revealing significant difference among the techniques (P = .001). Overall hydrocele formation rates were 8.24% in the Palomo technique series, 0.44% in the microsurgical varicocelectomy techniques, 2.84% in the laparoscopic varicocelectomy, and 7.3% in the macroscopic inguinal (Ivanissevich) or subinguinal varicocelectomy series, revealing significant difference among the techniques (P = .001). We conclude that the microsurgical varicocelectomy technique has higher spontaneous pregnancy rates and lower postoperative recurrence and hydrocele formation than conventional varicocelectomy techniques in infertile men. However, prospective, randomized, and comparative studies with large number of patients are needed to compare the efficacy of microsurgical varicocelectomy with that of other treatment modalities in infertile men with varicocele.

Microsurgical inguinal varicocelectomy with delivery of the testis: an artery and lymphatic sparing technique.

M GOLDSTEIN, B R Gilbert, A P Dicker … (1992)

Conventional techniques of varicocele repair are associated with substantial risks of hydrocele formation, ligation of the testicular artery, and varicocele recurrence. We describe a microsurgical technique of varicocelectomy that significantly lowers the incidence of these complications. The testicle is delivered through a 2 to 3 cm. inguinal incision, and all external spermatic and gubernacular veins are ligated. The testis is returned to the scrotum and the spermatic cord is dissected under the operating microscope. The testicular artery and lymphatics are identified and preserved. All internal spermatic veins are doubly ligated with small hemoclips or 4-zero silk and divided. The vas deferens and its vessels are preserved. Initially, we performed 33 conventional inguinal varicocelectomies in 24 men without delivery of the testis or use of a microscope. Postoperatively, 3 unilateral hydroceles (9%) and 3 unilateral recurrences (9%) were detected. For the next 12 cases 2.5x loupes were used resulting in no hydroceles but another recurrence (8%). We then performed 640 varicocelectomies in 429 men using the microsurgical technique with delivery of the testis. Among 382 men available for followup examination from 6 months to 7 years postoperatively no hydroceles and no cases of testicular atrophy were found. A total of 4 unilateral recurrent varicoceles (0.6%) was identified. The differences between the techniques in the incidence of hydrocele formation and varicocele recurrence are highly significant (p < 0.001). No wound infections occurred in any men. Four scrotal hematomas (0.6%), 1 of which required surgical drainage, occurred in the group with microsurgical ligation and delivery of the testis compared to none with the conventional technique. Preoperative and postoperative semen analyses (mean 3.57 analyses per patient) were obtained on 271 men. The changes in sperm count x 10(6) cc (36.9 to 46.8, p < 0.001), per cent motility (39.6 to 45.7%, p < 0.001) and per cent normal forms (48.4 to 52.10%, p < 0.001) were highly significant. The pregnancy rate was 152 of 357 couples (43%) followed for a minimum of 6 months postoperatively. Delivery of the testis through a small inguinal incision provides direct visual access to all possible avenues of testicular venous drainage. The operating microscope allows identification of the testicular artery, lymphatics and small venous channels. This minimally invasive, outpatient technique results in a significant decrease in the incidence of hydrocele formation, testicular artery injury and varicocele recurrence.

Advantages and limits of robot-assisted laparoscopic surgery: preliminary experience.

Julian C. Esposito, F Amato, A Settembre … (2004)

In the last few years, robotics has been applied in clinical practice for a variety of laparoscopic procedures. This study reports our preliminary experience using robotics in the field of general surgery to evaluate the advantages and limitations of robot-assisted laparoscopy. Thirty-two consecutive patients were scheduled to undergo robot-assisted laparoscopic surgery in our units from March 2002 to July 2003. The indications were cholecystectomy, 20 patients; right adrenalectomy, two points; bilateral varicocelectomy, two points; Heller's cardiomyotomy, two points; Nissen's fundoplication, two points; total splenectomy, one point; right colectomy, one point; left colectomy, 1 point; and bilateral inguinal hernia repair, one point. In all cases, we used the da Vinci surgical system, with the surgeon at the robotic work station and an assistant by the operating table. Twenty-nine of 32 procedures (90.6%) were completed robotically, whereas three were converted to laparoscopic surgery. Conversion to laparoscopy was due in two patients to minor bleeding that could not be managed robotically and to robot malfunction in the third patient. There were no deaths. Median hospital stay was 2.2 days (range, 2-8). The main advantages of robot-assisted laparoscopic surgery are the availability of three-dimensional vision and easier instrument manipulation than can be obtain with standard laparoscopy. The learning curve to master the robot was >or= 10 robotic procedures. The main limitations are the large diameter of the instruments (8 mm) and the limited number of robotic arms (maximum, three). We consider these technical shortcomings to be the cause for our conversions, because it is difficult to manage bleeding episodes with only two operating instruments. The benefit to the patient must be evaluated carefully and proven before this technology can become widely accepted in general surgery.
