Area of Science:

  • Surgical Innovation
  • Minimally Invasive Surgery
  • Gastrointestinal Surgery

Background:

  • Laparoscopic surgery requires safe abdominal access.
  • Traditional methods include Veress needle and open laparoscopy.
  • Assessing alternative techniques is crucial for patient safety.

Purpose of the Study:

  • To evaluate the feasibility and safety of the direct trocar technique for abdominal entry.
  • To compare complication rates associated with direct trocar entry versus other methods.
  • To determine if direct trocar technique can be performed without prior pneumoperitoneum.

Main Methods:

  • Retrospective review of 1500 patients undergoing laparoscopic cholecystectomy.
  • Categorization of abdominal access methods: direct trocar (1375 patients), Veress needle (106 patients), and open laparoscopy (19 patients).

  • Analysis of major complications, including enterotomy and omental herniation, related to primary access.

    • Main Results:

    • A total of 6 major complications (0.4%) occurred: 4 enterotomies and 2 omental herniations.
    • Enterotomies occurred in 3 patients (0.22%) during direct trocar entry and 1 patient during open laparoscopy.
    • Omental herniations were exclusively associated with open laparoscopy.

    Conclusions:

    • The direct trocar technique is a safe and feasible method for abdominal entry in laparoscopic surgery.
    • This technique eliminates the need for pre-insufflation (pneumoperitoneum).
    • Direct trocar insertion demonstrates a low rate of major complications, comparable to or better than traditional methods.
