Cul-de-sac insufflation: an easy alternative route for safely inducing pneumoperitoneum

Area of Science:

• Gynecologic surgery
• Minimally invasive procedures

Background:

• Routine cul-de-sac insufflation has been utilized since 1977 for laparoscopic procedures.
• Pneumoperitoneum induction is essential for creating space for laparoscopic visualization.

Purpose of the Study:

• To evaluate the efficacy and safety of cul-de-sac insufflation for pneumoperitoneum induction in women undergoing laparoscopy.
• To assess the failure rate and complications associated with this technique.

Main Methods:

• A total of 350 women underwent laparoscopy with pneumoperitoneum induced via cul-de-sac insufflation under local anesthesia.
• A specific intrauterine tenaculum and self-retaining speculum were used to facilitate accurate needle placement.
• Two manometers were employed to precisely determine the needle tip's position within the cul-de-sac.

Main Results:

• The initial failure rate was 3.6% (195 procedures), decreasing to 1.9% in subsequent cases (155 procedures).
• No serious operative complications were reported throughout the study.
• The technique proved reliable for achieving pneumoperitoneum in a large cohort.

Conclusions:

• Cul-de-sac insufflation is a safe and effective method for inducing pneumoperitoneum for laparoscopy.
• The technique is associated with a low and decreasing failure rate.
• Authors recommend cul-de-sac insufflation as the preferred method for pneumoperitoneum induction.
