Abstract
|
|
|
One hundred thirty two patients with symptomatic cholelithiasis were evaluated using endoscopic ultrasonography(EUS), standard abdominal ultrasonography(US) and endoscopic retrograde cholangiopancreatography(ERCP) for the detection of
choledocholithiasis prior to laparoscopic cholecystectomy. Twenty eight patients(21.2%) had choledocholithiasis and 21.4% of patients with common bile duct stones had normal sized ducts in US. Whole common bile duct was successfully examined in
all
patients by EUS, but only 65.9% of patients by US and 94.7% of patients by ERCP. EUS detected choledocholithiasis in 22 of 28 patients(89.3%), compared to 19 to 28 patients(67.9%) detected by US and 26 of 28 patients(92.9%) detected by ERCP.
While
no
complications as a result of EUS encountered, complications resulting from ERCP occured in 7 patients(5.3%), including cholecystitis in 2 patients, cholangitis in 3 patients and pancreatitis in 2 patients. These results suggest that EUS is more
sensitive than standard abdominal ultrasonography and as sensitive as ERCP in the detection of choledocholithiasis. In view of complication and failure rates. EUS appears to offer significant advantages over ERCP. We concluded that EUS is safe
and
effective imaging technique in the diagnosis of choledocholithiasis prior to laparoscopic cholecystectomy. (Korean J Gastroenterol 1994 ; 26 : 690-696).
