Conversion rates in laparoscopic colorectal surgery vary, with converted patients experiencing longer hospital stays and operative times. A clear definition of conversion is essential for future research comparing laparoscopic and open procedures.

Area of Science:

  • Colorectal Surgery
  • Minimally Invasive Surgery
  • Surgical Outcomes Research

Background:

  • Conversion rates in laparoscopic colorectal surgery show significant variability across studies.
  • The clinical outcomes for patients converted to open surgery remain a subject of debate.

Purpose of the Study:

  • To analyze conversion rates and outcomes in laparoscopic colorectal surgery.
  • To identify factors influencing conversion and provide recommendations for future research.

Main Methods:

  • A comprehensive literature search was conducted up to May 1999.
  • Analysis included 28 studies comprising 3232 patients undergoing laparoscopic colorectal surgery.

Main Results:

  • The overall conversion rate was 15.38%. Studies lacking a clear definition reported lower conversion rates (13.7% vs. 18.9%).

  • Converted patients experienced significantly longer hospital stays (11.38 vs. 7.41 days) and operative times (209 vs. 189 minutes).
  • Factors associated with increased conversion included left colectomy, anterior resection, diverticulitis, and cancer.

    • Conclusions:

    • Approximately 85% of colorectal resections are completed laparoscopically in nonrandomized studies.
    • A standardized definition of conversion is crucial for comparing results from randomized trials.
    • Future trials should account for a potential 20% conversion rate in sample size calculations due to the distinct outcomes of converted patients.
