BACKGROUND: Although laparoscopic colon and rectal surgery can be safely performed in the hands of well-trained surgeons, criteria for patient selection should be further developed in order to decrease the conversion rate. The main objective of this study was to identify predictive factors for conversion of laparoscopic colorectal surgery to an open procedure based on statistical analysis. METHODS: A retrospective survey was performed using data collected from 400 patients who underwent laparoscopic colorectal surgery between March 2000 and December 2006. As potential predictive factors for conversion, we considered demographic characteristics, surgery-related variables and disease-related variables. Univariable analysis was performed to identify individual predictive risk factors for conversion. Factors with p values below 0.05 were included in a regression model. RESULTS: Conversion to open surgery was required in 51 patients (12.7%). Age (>65 years) was the only independent predictive demographic factor (OR=2.3; 95% CI, 1.25-4.46). Low anterior resection (OR=3.9; 95% CI, 1.64-9-18) and complicated diverticulitis (OR=3.9; 95% CI, 1.64-9.18) were also predictive factors. The only predictive factor evidenced in the multivariate analysis was complicated diverticulitis (OR=159.99; 95% CI, 41.02-624.02). Indications for conversion were: adhesions in 53% of the patients, technical problems in 18%, bleeding in 1%, and other indications for the remaining 28%. CONCLUSION: Complicated diverticulitis or cancer of the rectum treated by low anterior resection have higher probabilities of conversion.
