[Single-port technique in laparoscopic surgery].

Laparoscopic operations using only one trocar (single-port technique) have the aim to further minimize the trauma of access incisions similar to NOTES. To carry this out special trocars and instruments are needed which are presented in this article with respect to application and function. The range of indications corresponds to the conventional laparoscopic surgery. Recent publications have shown that operations using a single-port technique are safe and efficient. Greater technical difficulties and higher costs must be considered. For the identification of significant advantages, randomized studies are still lacking.
