The Laparoscopic Single-channel Varicocele Dissection (LEVD)

The new technique in pediatric surgery

Single-channel Laparo-Endoscopic Varicocele Dissection (LEVD) is a new surgical procedure in pediatric surgery. The "scarless" intervention is associated with the reduction of surgical trauma and is carried out as an outpatient procedure.

By contrast with previous standard laparoscopic procedures using 3-trocar technology, the surgeon only uses one port in LEVD (single-port technique) through which the operating laparoscope and in turn the instrument set can be inserted. The mini-operating laparoscope with integrated 3.5 mm working channel is a key element for the new surgical technique. Like all classic operating laparoscopes, the mini-operating telescope has a viewing direction of 0 degrees. This is a prerequisite for the use of auxiliary instruments which are therefore applied through the integrated working channel in the same axis. The perfectly harmonized operating set is completed by a 3.5 mm instrument set in monopolar and bipolar versions.


New special bipolar forceps
The new bipolar jaw insert was specially designed in accordance with the suggestions of PD Dr. Bühligen*. The distal offset permits reliable holding of the structure to be coagulated and prevents the vessels sliding out of the jaws. The surgeon can reliably create an adequate gap to the underlying tissue before the coagulation procedure is started.

  • Small operating laparoscope with only 5.5 mm diameter      
  • Optimum image quality with 50.000 pixels
  • Large working channel for 3.5 mm instruments
  • Ergonomic design
  • The working instrument set being used can be quickly changed and is always visible through the scope

*The compact instrument set was created for this innovative method in the course of cooperation with PD Dr. med. Ulf Bühligen, Senior Surgeon at the Clinic and Polyclinic for Pediatric Surgery at Leipzig University.
