Gasless laparoscopic colonic surgery is feasible, avoiding complications associated with carbon dioxide insufflation (CDI). This technique allows for minimal access surgery without the need for gas insufflation.

Area of Science:

  • Minimally Invasive Surgery
  • Colorectal Surgery
  • Surgical Technology

Background:

  • Laparoscopic surgery for colonic and rectal operations commonly uses carbon dioxide insufflation (CDI).
  • CDI can lead to cardiopulmonary complications.
  • Alternative methods for laparoscopic colonic surgery are being explored.

Purpose of the Study:

  • To evaluate the feasibility of gasless laparoscopic colonic surgery.
  • To determine if carbon dioxide insufflation is essential for laparoscopic colonic procedures.

Main Methods:

  • A novel retractor was used to lift the abdominal wall.
  • Operations were performed through a small incision (3-5 cm) using laparoscopic and conventional instruments.
  • The study involved 67 patients undergoing colonic surgery.

Main Results:

  • Gasless laparoscopic technique was successfully completed in 61 out of 67 patients (91%).
  • Six patients (9%) required conversion to open surgery.
  • Postoperative complications included bleeding, anastomotic issues, and hernia; 7% required reoperation.
  • In 53 patients with colonic cancer, only 2% experienced hepatic recurrence during follow-up, with no port site recurrence.

Conclusions:

  • Gasless laparoscopic colonic surgery is technically achievable.
  • Carbon dioxide insufflation is not a prerequisite for performing minimal access colonic surgery.
