Gasless laparoscopy offers potential advantages over traditional pneumoperitoneum by increasing surgeon mobility and reducing complications. This technique uses a wall retractor for abdominal access, enabling standard instruments and improved visualization during procedures.

Area of Science:

  • Minimally Invasive Surgery
  • Surgical Technology

Background:

  • Pneumoperitoneum is standard for laparoscopy but restricts surgeon movement and can cause complications.
  • Current laparoscopic techniques rely on insufflating the abdomen with carbon dioxide (CO2).

Purpose of the Study:

  • To evaluate the feasibility and outcomes of gasless laparoscopic surgery.
  • To assess the advantages of gasless laparoscopy compared to traditional CO2 pneumoperitoneum.

Main Methods:

  • A fan-shaped wall retractor attached to an electric lift arm was used to raise the abdominal wall under direct vision.
  • Laparoscopic procedures were performed without pneumoperitoneum, allowing the use of standard surgical instruments.
  • Fifty-four patients underwent gasless laparoscopy for various procedures including cholecystectomy, abdominal exploration, liver cyst fenestration, and appendectomy.

Main Results:

  • Gasless laparoscopy allowed for increased surgeon freedom of action and use of conventional instruments.
  • Unlimited suction was achievable without loss of exposure.
  • Complications included three wound infections, and six procedures required conversion to open surgery.

Conclusions:

  • Gasless laparoscopy demonstrates potential advantages over CO2 pneumoperitoneum, including improved surgical ergonomics and the use of standard instruments.
  • The technique is feasible for a range of abdominal procedures.
  • Further research is warranted to fully elucidate the benefits and limitations of gasless laparoscopy.
