Risk factors for conversion of laparoscopic colorectal surgery to open surgery: does conversion worsen outcome?
The conversion rate in colorectal surgery was 16.6 %. Converted patients had significantly higher rates of morbidity and mortality compared to successfully completed laparoscopic cases, although lower than open cases. Crohn's disease, prior abdominal surgery, and proctectomy are the strongest predictors for conversion of laparoscopic to open in colorectal operations.
TNM classification could be considered as a reliable predictor of early postoperative mortality, but has no role in the prediction of early postoperative morbidity after colorectal resections.
