Conversion Rates, Causes and Preoperative Associated Factors in 3411 Laparoscopic Appendectomies: Insights after nearly three decades of laparoscopy and an analysis of the Learning Curve

Laparoscopic appendectomy is the current gold standard in treating acute appendicitis. Despite the low frequency of conversion to open surgery, it remains necessary in certain cases. Our primary outcome was to identify the conversion rate of laparoscopic appendectomy to open surgery and how this rate has changed over the learning curve. Second, we aim to determine the causes of conversion, their changes in frequency over time and to identify preoperative factors associated with conversion.
