ABSTRACT
Objective To determine the value of ERCP and EST after Billroth gastroenterostomy. Methods ERCP was used in 31 patients after Billroth- Ⅰ gastroenterostomy, 12 of whom received EST. It was in 137 patients after Billroth-Ⅱ gastroenterostomy, of the 34 received EST and 4 EPBD.Results Billroth- Ⅰ gastroenterostomy ERCP was successfully performed in 28 out of the 31 patients and EST in 11 out of the 12 patients. Billroth- Ⅱ gastroenterostomy ERCP was successfully performed in 109 out of the 137 patients and EST in 31 out of the 38 patients. There were no serious complications in patients receiving endoscopic treatments. Concluasion The success rates of ERCP and EST are high in patients with bile duct lithiasis after Billroth-gastroenterostomy. Endoscopic treatment or cholangioduodenostomy has good therapeutic effects.
ABSTRACT
Objective To discuss the application of the bolus chasing DSA technology in angiography in thoracic, abdominal, common iliac and four limbs′ arteries. Methods Bolus chasing DSA with Mask Before program of the system was performed in 40 procedures in 25 patients, using the control handle to control the moving of the bed, and obtained the real time bolus chasing DSA pictures at the blood stream speed. Results In the 40 procedures, photographing in 35 had good qualities, accounting for 87.5%, but not good in 5, accounting for 12 5%, which could still meet the request of diagnosing after non subtraction processing. Conclusion Bolus chasing DSA could display a large scale of anatomical skeleton and blood stream condition from chest to the four limbs exactly. It was a new method that could be taken to observe real time continuous multi sections of blood vessel structure.
