How long does laparoscopic surgery really take? Lessons learned from 1000 operative laparoscopies

Area of Science:

• Gynecological Surgery
• Minimally Invasive Procedures
• Surgical Outcomes Analysis

Background:

• Laparoscopic surgery is a common approach in gynecology.
• Accurate assessment of operative times is crucial for surgical scheduling and resource allocation.
• Variability in procedure duration can impact operating room efficiency.

Purpose of the Study:

• To evaluate the operating times for common gynecological laparoscopic procedures.
• To identify factors influencing procedure duration.
• To assess the predictability of operative times for scheduling purposes.

Main Methods:

• Retrospective analysis of 1000 consecutive operative laparoscopies.
• Exclusion of diagnostic laparoscopy and laparoscopic sterilization.
• Categorization of procedures into six major groups for analysis.

Main Results:

• The average operating time across all analyzed procedures was 76.9 minutes (range: 10-400 minutes).
• Procedures for ectopic pregnancy and tubal disease averaged around 60 minutes.
• Surgery for endometriosis and ovarian cysts averaged 72 minutes.
• Laparoscopic myomectomy and hysterectomy had longer average times of 113 and 131 minutes, respectively.
• 3.8% of cases (38) required conversion to laparotomy.

Conclusions:

• While many gynecological laparoscopic procedures are completed within 75 minutes, there is significant variability in operating times.
• The wide range and unpredictability of procedure durations pose challenges for efficient operating theatre session utilization.
