Laparoscopic Single-Port Varicocelectomy (LEVD)

A new technique in pediatric surgery

Laparoscopic single-port varicocelectomy (LEVD) is a new approach in pediatric surgery. This "scarless" method reduces surgical trauma and makes the procedure possible on an outpatient basis.

Unlike earlier standard laparoscopic procedures with a three-trocar technique, in LEVD the surgeon introduces the laparoscope and surgical instruments one after the other through a single access (single-port technique).

The key to the new technique is a miniature operating laparoscope with an integrated 3.5 mm working channel. Like all conventional surgical laparoscopes, the miniature operating telescope has a 0° direction of view – the prerequisite for using auxiliary instruments on the same axis through the integrated working channel. The surgical set is perfectly complemented by a 3.5 mm monopolar and bipolar instrument set.

Dedicated bipolar forceps

Based on Dr. Bühligen's concept, we designed a new bipolar forceps insert. Its offset distal design holds the structures to be coagulated securely and prevents vessels from slipping out of the jaws. Before coagulation begins, the surgeon can keep the structures at a safe distance from the underlying tissue.

Dr. Ulf Buhligen, MD

Together with Dr. Ulf Buhligen, senior physician at the pediatric surgery outpatient clinic and polyclinic of Leipzig University Hospital, we developed an integrated instrument set for this innovative method.
