ABSTRACT
Objective To study the effect of MRCP for operation difficulty assessment before laparoscopic cholecystectomy. Methods 110 patients with gallbladder stone were randomly selected from March 2011 to July 2012 in our hospital,and all the patients were given LC operation after examined by MRCP. Regarded the average operation time 30 min as a criterion,when the operation time was no more than 30 min,the operation was considered as normal operation;when the operation time was more than 30 min, the operation was considered as op-eration of a certain degree of difficulty. Made a correlation analysis between LC operation difficulty and age,gender,location,volume of gall-bladder,angle of ductus cysticus, thickness of gallbladder wall, circumstances surrounding the cystic duct, length of ductus cysticus, and whether there were calculus in the cervical part of gallbladder. Results The difficulty level of LC operation is related to length of ductus cys-ticus and whether there were calculus in the cervical part of gallbladder,and there is no correlation with age,gender,location,volume of gall-bladder,angle of ductus cysticus,thickness of gallbladder wall,circumstances surrounding the cystic duct. Conclusion Routinely MRCP test in preoperative patients is of important significance to the prediction of LC operation difficulty.
