Comparation of two types of minimal invasive surgery for treating cholecystolithiasis with choledocholithiasis

Objective To evaluate the effect of laparoscopic cholecystectomy(LC) combined with bile duct exploration and stone removal(BDE) and LC with endoscopic sphincterotomy(EST) in treating cholecystolithiasis with choledocholithiasis.Methods Among 256 cases of cholecystolithiasis and choledocholithlasis,132 patients were treated by LC+LCBDE,and 124 cases by EST combined with LC.The operation success rate,operation time and cost,complication rate,and length of hospital stay of the two groups were compared.Results There was no statistical difference in the operation success rate,complication rate,stone clearance rate,and average hospital stay between the two groups,but EST+LC group had significantly longer operation time and higher cost.Conclusions There are respective indications,advantages and disadvantages in the two groups.EST+LC is the better choice for patients with diameter of CBD1.0 cm,stones impacted in the distal CBD,or old age.Otherwise,for patients with diameter of CBD1.0cm and with multiple choledocholithiasis,especially for middle-aged patients,the better way is LC+LCBDE.
