Abstract:
Objective To compare the successful ratio, efficacy and complications between ultrasound-guided and X-ray-guided endoscopic biliary drainage (EBD). Methods EBD was performed in 62 patients under ultrasound guidance and 54 patients under X-ray guidance. Serum bilirubin, the bile duct diameter and the changes of clinical symptoms were compared before and after the procedure. Results Tube placement was successfully achieved in 54 of 62 patients under ultrasound guidance and 51 of 54 patients under X-ray guidance. The serum direct bilirubin and the common bile duct diameter in patients with ultrasound guidance before and one week after procedure were (205.41±115.27) μmol/L vs. (106.47±82.16) μmol/L and (12.6±7.1) mm vs. (8.5±3.1) mm, respectively, with significant difference (all P values<0.05). Whereas they were (211.14±106.25) μmol/L vs. (110.89±59.47) μmol/L and (13.1±7.0) mm vs. (8.8± 3.2) mm, respectively, in patients with X-ray guidance (P<0.05). No complications such as abdominal pain, fever and elevated amylase were found in patients with ultrasound guidance, while 3 patients (5.9%) with X-ray guidence had above complications. Conclusions X-ray is a most effective method in guidance of EBD. However, ultrasound guidence, which may avoid unfavorable factors such as X-ray radiation and allergic contrast agent, has some advantages including real-time display, mobile convenience and emergency bedside application. It can instead of X-ray in performance of endoscopic nasobiliary drainage and endoscopic retrograde biliary drainage in patients with bile duct stone and mild narrow ducl caused by tumors.
