A risk score for conversion from laparoscopic to open cholecystectomy.

摘要: Background: Laparoscopic cholecystectomy has become the standard operative procedure for cholelithiasis, but there are still some patients requiring conversion to open mainly because of technical difficulty. Our aim was develop a risk score prediction from laparoscopic cholecystectomy. Methods: Preoperative clinical, laboratory, and radiologic parameters 1,000 who underwent were analyzed their effect on rates. Six (male sex, abdominal tenderness, previous upper operation, sonographically thickened gallbladder wall, age over 60 years, preoperative diagnosis acute cholecystitis) found have significant in multivariate analysis. A constant coefficients these variables calculated formed score. Results: Overall 48 required (4.8%). These had significantly higher scores (mean 6.9 versus −7.2, P <0.001). Increasing resulted with increases rates probabilities (P Ideal cut-off point this −3; rate 1.6% under −3, 11.4% value <0.001). Conclusions: Conversion can be predicted easily by score. Patients having high may informed scheduled appropriately. An experienced surgeon operate patients, he or she make an early decision convert case
