| pubmed-article:8731964 | pubmed:abstractText | 15 patients with left/right intrahepatic bile-duct calculi received ultrasonic lithotresis via abdomen by using the percutaneous cholecystoscope and ultrasonic lithotresis apparatus. The results indicated that all the surgical manipulations were successful with a residual rate of 6.7%, compared with a residual rate of 78.2% in 23 cases of left/right intrahepatic bile-duct lithiasis treated simultaneously by lithotomy apparatus. The differences between them were statistically significant (u = 4.29, P < 0.01). Among 12 cases undergoing follow-up observation, no side effect due to ultrasonic lithotresis and no residual calculus after 2-4 check-ups with B-mode ultrasound diagnostic set were found and all of their symptoms disappeared except for 1 case. | lld:pubmed |
