In the last 10 years, there has not been an abdominal surgical procedure that has not been performed by laparoscopic means. The enthusiasm of surgeons active in this field often neglects problems, especially with basic instruments which are important vehicles for the laparoscopic technique. The purpose of this study was to focus on trocar-related problems with special respect to the tip design. On the basis of a prospective study of laparoscopic transperitoneal hernia repair (TAPP) and laparoscopic Nissen fundoplication, we evaluated our data concerning trocar-related complications at the abdominal wall. We compared two groups of patients treated in a nonrandomized design with either sharp cutting single-use trocars or cone-shaped non-cutting reuseable trocars. The evaluation of our own data showed an incisional hernia in 1.83% of patients treated with a sharp trocar tip, a complication which could be significantly lowered, to 0.17%, with a conic tip design. Similar results could be seen with trocar-related bleeding events at the insertion site in the abdominal wall. In most publications, trocar design and related complications are unmentioned. Our data demonstrate a reasonable benefit for a conic tip design, which enables atraumatic insertion through the abdominal wall. The reuseable steel version furthermore holds a considerable cost-saving potential.
