Area of Science:

  • Minimally Invasive Surgery
  • Surgical Techniques

Background:

  • Traditional laparoscopy often involves Veress needles and sharp trocars, posing risks of injury and carbon dioxide leakage.
  • Fascial sutures are sometimes required to secure trocars and prevent gas leakage, adding complexity to the procedure.

Purpose of the Study:

  • To evaluate the effectiveness of a novel blunt trocar technique for laparoscopy.
  • To assess the procedural time and skin incision length associated with blunt trocar use.
  • To compare outcomes based on patient Body Mass Index (BMI).

Main Methods:

  • A prospective study was conducted on 33 consecutive patients.
  • The blunt trocar technique was employed, omitting Veress needles and sharp primary trocars.
  • Procedural time and skin incision length were meticulously recorded and analyzed in relation to patient BMI.

Main Results:

  • The blunt trocar technique required an average of 3.5 ± 1.3 minutes.
  • The average skin incision length was 14 ± 2 mm.
  • Even in obese patients (BMI > 30 kg/m²), the procedure averaged only 4.0 ± 1.6 minutes with no reported carbon dioxide leakage or complications.

Conclusions:

  • Blunt trocar laparoscopy is a safe and effective alternative to traditional methods.
  • The technique is relatively quick and minimizes incision size, offering advantages for patient outcomes.
  • It presents a viable option for various patient populations, including those with higher BMIs.
