Isopneumic laparoscopy in general surgery and trauma: an update

Area of Science:

• Minimally Invasive Surgery
• Surgical Technology
• Laparoscopic Procedures

Background:

• Traditional laparoscopic surgery relies on carbon dioxide pneumoperitoneum for abdominal distention.
• This method can cause physiological complications.
• Alternative methods for abdominal distention are being explored.

Purpose of the Study:

• To assess a retractor system enabling laparoscopic surgery without carbon dioxide pneumoperitoneum.
• To determine if this system facilitates the use of traditional surgical instruments.
• To evaluate the efficacy of isopneumic laparoscopy.

Main Methods:

• Prospective evaluation of 88 isopneumic laparoscopic procedures.
• Utilized a planar abdominal wall distention system with an intra-abdominal fan retractor and mechanical arm.
• Conventional and laparoscopic instruments were used in all cases.

Main Results:

• Laparoscopy without pneumoperitoneum was used in 43 trauma patients, obviating formal exploration in 81%.
• Repairs of enterotomies, diaphragmatic lacerations, and gastric perforations were performed with conventional instruments.
• Adequate abdominal exposure was achieved in 37 of 45 cases, with a low complication rate.

Conclusions:

• Laparoscopic surgery can be performed without pneumoperitoneum in most cases.
• The ability to use conventional surgical instruments is a significant advantage.
• Further improvements in distention systems and instrument modifications are needed to expand isopneumic laparoscopy's role.
