Abstract |
Sharp trocar insertion for laparoscopic procedures carries with it increased risk for vascular and visceral complications and incisional hernia. In a trial, which randomized 87 patients to treatment with either sharp trocars or a radially expanding needle system with blunt dilator, results showed that with the latter system there was statistically improved patient assessment of pain, a lower complications rate, and shorter procedure time. In the group of patients randomized to treatment with conventional trocars, there were a total of six instrument-related adverse events (6/42): four cases (five incidences) of abdominal wall injuries and one small bowel perforation caused by a Veress needle. Of the 45 patients randomized to the blunt dilator/ cannula treatment, there was one adverse event (1/45) that was unrelated to the blunt dilator/ cannula system: Veress needle injury to abdominal vasculature. The radially expanding access system demonstrates statistically improved patient postoperative comfort and improved patient safety.
