RESUMEN
Objective@#To evaluate diagnostic efficacy of endoscopic ultrasonography (EUS) for extra-hepatic bile duct dilation of unknown reasons which failed to be identified by traditional radiological methods.@*Methods@#Data of consecutive 892 patients who underwent EUS from February 2016 to September 2017 were retrospectively studied. Final diagnosis was determined by endoscopic retrograde cholangiopancreatography (ERCP)-based biopsy, surgical pathology, or a follow-up of at least 10 months.@*Results@#A total of 82 patients with extra-hepatic bile duct dilation (width ≥ 7 mm) and mean age of 61.5±9.6 years were included. The width of common bile duct was 13.0±4.25 mm. Reasons for extra-hepatic bile duct dilation could be determined by EUS in most patients with abnormal liver function. No malignant causes were detected in patients with normal liver function. The diagnostic sensitivity, specificity, accuracy, positive predictive value and negative predictive value of EUS were 92.7%, 100.0%, 96.3%, 100.0%, and 93.2%, respectively.@*Conclusion@#For patients with dilated extra-hepatic bile duct without clear etiology, EUS may be an alternative for determining the etiology of extra-hepatic bile duct dilation. For those with extra-hepatic bile duct dilation with abnormal liver function, malignant causes should not be neglected.
RESUMEN
Objective To evaluate diagnostic efficacy of endoscopic ultrasonography ( EUS ) for extra-hepatic bile duct dilation of unknown reasons which failed to be identified by traditional radiological methods. Methods Data of consecutive 892 patients who underwent EUS from February 2016 to September 2017 were retrospectively studied. Final diagnosis was determined by endoscopic retrograde cholangiopancreatography (ERCP)-based biopsy, surgical pathology, or a follow-up of at least 10 months. Results A total of 82 patients with extra-hepatic bile duct dilation (width ≥7 mm) and mean age of 61. 5±9. 6 years were included. The width of common bile duct was 13. 0±4. 25 mm. Reasons for extra-hepatic bile duct dilation could be determined by EUS in most patients with abnormal liver function. No malignant causes were detected in patients with normal liver function. The diagnostic sensitivity, specificity, accuracy, positive predictive value and negative predictive value of EUS were 92. 7％, 100. 0％, 96. 3％, 100. 0％, and 93. 2％, respectively. Conclusion For patients with dilated extra-hepatic bile duct without clear etiology, EUS may be an alternative for determining the etiology of extra-hepatic bile duct dilation. For those with extra-hepatic bile duct dilation with abnormal liver function, malignant causes should not be neglected.

Objective To evaluate effects of flush fluid of different temperatures on pain, comfort and adverse reactions in patients receiving choledochoscopy via T tube for residual bile duct stones. Methods Patients who underwent choledochoscopy were divided into the experimental group ( 36℃ saline was used as flush fluid) and control group ( room temperature saline was used as flush fluid) randomly. Pain degree, comfort degree, procedure time, the total amount of flush fluid, infusion speed and adverse reactions were recorded and analyzed. Results A total of 100 cases were included, 50 cases in each group. There was no significant difference between the two groups in their education level, working condition, operation methods, T-tube size, necessity for lithotripsy, procedure time, total amount of flush fluid and infusion speed (all P>0. 05). The pain scores were 1. 0(1. 00, 2. 00) and 2. 0(1. 00, 3. 25) (Z=-2. 158,P=0. 031) and the comfort scores were 6. 0(5. 00, 7. 25) and 5. 0(2. 00, 6. 00) (Z=-3. 384,P=0. 001) in the experimental group and the control group, respectively. There was significant difference in the change rate of heart rate during and before procedure between the two groups (-4. 07％± 10. 76％ VS 0. 30％± 10. 23％, P=0. 046) . The incidence of postoperative diarrhea in the experimental group and the control group was 6％( 3/50) and 22％ ( 11/50 ) , respectively (χ2=5. 316, P=0. 021 ) . Conclusion 36℃ saline flush can reduce pain scores, improve comfort degree and reduce the incidence of postoperative diarrhea after procedure in patients undergoing choledochoscopy via T tube.
RESUMEN
This paper summarized nursing points for caring 12 cases undergoing endoscopic ultrasonography guided biliary drainage(EUS-BD) in the treatment of malignant obstructive jaundice.All patients received EUS-BD after unsuccessful endoscopic retrograde cholangiopancreatography,including 5 patients undergoing EUS guided hepaticogastrostomy(EUS-HGS) and 7 patients undergoing EUS guided choledochoduodenostomy(EUS-CDS).Nursing points included:preoperative assessment,psychological care,preoperative gastrointestinal preparation,intraoperative cardiopulmonary function monitoring,collaboration in operation,postoperative monitoring,observation and nursing care for complications such as bleeding,bile leakage and the others.The average hospital stay was 10～16 d.Two patients developed complications(16.67％).A patient undergoing EUS-HGS developed bile leakage,biliary peritonitis,and pneumoperitoneum after the procedure,but was successfully recovered by placement of a second fully covered self-expendable metal stent in the primary metal stent,percutaneous abdominal drainage and antibiotic treatment.A patient undergoing EUS-CDS developed gastrointestinal bleeding,and was successfully treated with radiological intervention.
