Abstract
Common bile duct stones represent a significant danger to patients because they can lead to biliary colic, obstructive jaundice, cholangitis, or pancreatitis. Common bile duct stones either migrate from the gallbladder or form primarily within the bile ducts themselves.
In patients who have gallstones, and in whom a cholecystectomy is considered, common bile duct stones can be found preoperatively, intraoperatively, or postoperatively. Ten percent to 15% of patients undergoing cholecystectomy will be found to have choledocholithiasis.
Choledocholithiasis is suspected preoperatively in those patients who have elevated liver function studies, jaundice, pancreatitis, radiologic signs.
Aim of the study:
The aim of the study is to evaluate laparoscopic exploration of the CBD in patient with choledocholithiasis and to evaluate intraoperative time, intraoperative blood loss and postoperative hospital stay.
Patients and methods:
This study is carried out in department of general surgery in Minia university hospital and Misr university for science and technology hospital during the period from 2012 to 2013. Each patient is evaluated by the surgical team as regard the patient complain , patient presentation, history of jaundice, pancreatitis the presence of intrahepatic biliary radical dilatation and the CBD diameter.
The study involved 11 patients. Each patient was investigated be abdominal US, abdominal CT, liver function test including ALT,AST, total and direct bilirubin.
Laparoscopic choledochotomy with placement of t-tube in the CBD and suturing of the CBD in all patients was done. Postoperative T-tube cholangiogram was done to ensure complete clearance of the duct.
Results:
Complete duct clearance was achieved in 9 patients (85%). Duct clearance was incomplete in two patients. The two patients underwent open exploration of common bile duct for an impacted stone.
Mean operation time was 95 (range 80-110) min with a mean postoperative hospital stay of 14 (range 10-18) days. There were no postoperative deaths.
Complications occurred as postoperative ileus, bile leak and port site infection.
