ABSTRACT

Methods: 796 subjects have been studied and been into surgery from January 2001 to December 2009. The mean age is 53 years with sex predominance for females 84%. Elective surgery for 92.3% and urgent surgery in 7.7%. Average surgical time was 54 minutes. Results: By using the conversion to open surgery risk scale 45 subjects (5.7%) were classified as high risk and the conversion to open surgery was realized for 38 patients (4.8%). The most common causes for conversion to open surgery were bleeding from gallbladder bed (3%) and poor visualization of common bile ducts (0.9%). There were complications for 11 subjects, nine had retained choledocholithiasis and one had liver abscess due to common bile duct compression this subject were surgically treated twice. One subject had common bile duct injury not detected at the time of operation, solved later with biliary enteric anastomosis. Conclusion: This risk scale allows the surgeon to predict with reliability the risk that a patient has for conversion to open surgery that formerly was laparoscopic. With 89% sensibility and 98% specificity and a positive predictive value of 71% and negative predictive value of 99%. The conversion rate indicates that there is no complication free procedure.
