Blunt trocar laparoscopy.
A technique, termed blunt trocar laparoscopy, has been developed to avoid the use of both Veress needles and sharp primary trocars and to avoid carbon dioxide leakage without the use of fascial sutures. To evaluate this technique's effectiveness, the time required and the length of the skin incision was evaluated prospectively in 33 consecutive unselected patients and the results were compared with the patient's BMI. The blunt trocar technique took 3.5 +/- 1.3 minutes (mean +/- SD) to perform and the average incision length was 14 +/- 2 mm. Although the time of the procedure increased slightly with the BMI, even in the obese patients (BMI > 30 kg/m2; n = 10), the average time for the procedure was only 4.0 +/- 1.6 minutes. No carbon dioxide leakage or complications occurred in any patient. The results of this study indicate that a blunt trocar technique may be a useful and relatively quick alternative approach for laparoscopy.
