SAFETY OF THE OPTICAL TROCAR AS A METHOD OF 1st LAPAROSCOPIC ACCESS VS DIRECT TROCAR, VERESS AND HASSON NEEDLE

Abstract

Background: Laparoscopic surgery is a surgical procedure by which access to the abdomino-pelvic cavity is obtained through small incisions. The incidence of bowel injury is estimated at 0.5% and of injury to major blood vessels (iliac, aorta, cava) at the time of access at 1%. Theoretical benets of optical trocar access include immediate and/or early recognition of injury, as well as failed entry, on the assumption that the layers of the abdominal wall are observed with the optical trocar until access has been achieved. To determine whether the optical trocar is a saferObjective: laparoscopic access method compared to the other techniques with direct trocar, Veress needle and Hasson open technique. Material and Methods: Observational, analytical, prospective cohort study with four arms. The study included women over 18 years of age who attended the gynaecology and laparoscopic surgery department of the Hospital Ángeles del Pedregal. The number of attempts and access time, as well as the presence of complications were quantied. Results and Conclusions: Trocar access had an advantage over the other techniques, both in access time and lower incidence of complications. The number of attempts to enter the cavity was similar to the open technique. We can conclude that the optical trocar technique is safer than the other techniques even over the open technique (Hasson).
