RESUMO
Objective:To investigate the risk factor analysis and model prediction of bleeding after endoscopic retrograde cholangiopancreatography in patients with malignant obstructive jaundice (MOJ).Methods:A retrospective analysis was performed on 302 patients with MOJ treated with ERCP who were treated in the No. 363 Hospital Affiliated to Southwest Medical University from January 2015 to June 2021. The general clinical data of the patients were collected, and the biochemical indicators of the pancreatic and bile ducts were detected. The patients were followed up after discharge, and the patients were divided into a bleeding group ( n=47) and a control group ( n=255) according to whether the follow-up patients were bleeding after ERCP. Compared the general and clinical data of the two groups of patients, including age, gender, platelet count, presence of bile duct stones, acute cholangitis, acute pancreatitis, number of stones, intraoperative bleeding, pancreatic cancer, cholangiocarcinoma, large stone diameter, stone incarceration, duodenal papillary diverticulum, and pre-surgical incision. The measurement data that obey the normal distribution were represented by the mean±standard deviation ( ± s), and the two independent sample t test was used for the comparison between groups; the data that do not conform to the normal distribution were represented by M ( Q1, Q3), and the comparison between groups was used Mann-Whitney U test. The comparison of enumeration data between groups adopted chi-square test. Logistic multivariate regression was used to analyze the independent risk factors of postoperative bleeding after ERCP, and a nomogram prediction model was established and verified according to the independent risk factors of postoperative bleeding. Results:The two groups of patients were compared in age, gender, platelet count, bile duct stones, acute cholangitis, acute pancreatitis, the number of stones, intraoperative bleeding and other aspects, the difference was not statistically significant ( P>0.05). The percentages of pancreatic cancer, cholangiocarcinoma, large stone diameter, stone incarceration, duodenal papillary diverticulum, and surgical pre-incision in the bleeding group were 12.77%, 17.02%, 19.15%, 51.06%, 59.57%, and 14.89%, respectively. , the percentages of the control group were 3.92%, 5.10%, 9.02%, 19.22%, 17.65%, and 5.88%, and the difference was statistically significant between the two groups ( P<0.05). Taking postoperative bleeding as the dependent variable, and using the indicators with statistical differences in univariate analysis as independent variables, multivariate Logistic regression analysis showed that the patient had pancreatic cancer ( OR=1.838, 95% CI: 1.524-4.613, P=0.041), cholangiocarcinoma ( OR=2.548, 95% CI: 1.870-5.116, P=0.015), stone incarceration ( OR=3.078, 95% CI: 2.374-6.012, P<0.001), duodenum Intestinal papillary diverticula ( OR=1.140, 95% CI: 1.045-1.628, P<0.001), surgical pre-incision ( OR=1.640, 95% CI: 1.321-1.928, P<0.001) were associated with postoperative bleeding in MOJ patients after ERCP independent risk factors. The predictive ability of duodenal papillary diverticulum was the highest; the predictive ability of stone incarceration and cholangiocarcinoma was the second, and there was no significant difference between them; the predictive ability of pancreatic cancer, stone diameter, and pre-incision on bleeding after ERCP in MOJ patients smaller. Pancreatic cancer, cholangiocarcinoma, large stone diameter, stone incarceration, duodenal papillary diverticulum, and pre-incision scores were 42, 63, 28, 65, 76, and 34 points respectively, and the total score was 308 points corresponding to the nomogram model. The predictive power of the nomogram was 61.6%, and overall, the nomogram had good predictive performance. Harrell concordance index analysis and ROC curve were used to evaluate the model discrimination, the C-index calculation result was 0.826 (95% CI: 0.771-0.847), the ROC curve AUC was 0.843 (95% CI: 0.801-0.884), and the ROC prediction The value and the calculation result of C-index are relatively close. The model discrimination is applied in this study and has a certain prediction effect. The nomogram model in the Calibration curve predicted the probability of postoperative bleeding after ERCP in MOJ patients with high consistency with the actual probability. Conclusion:ERCP is safe and feasible for most patients with MOJ, but for patients with pancreatic cancer, bile duct cancer, large stone diameter, stone incarceration, and duodenal papillary diverticulum, it should be performed with caution, and preoperative incision should be avoided, to reduce the risk of postoperative bleeding. In addition, the nomogram model has a strong predictive ability in predicting bleeding after ERCP in patients with MOJ, which is worthy of reference in clinical research.
RESUMO
Objective:To investigate the effects of different preoperative biliary drainage methods on bile bacterial culture and drug resistence of malignant obstructive jaundice.Methods:The retrospective and descriptive study was conducted. The clinical data of 317 patients with malignant obstructive jaundice who were admitted to the First Medical Center of Chinese PLA General Hospital from January 2015 to December 2018 were collected. There were 216 males and 101 females, aged (62±10)years. Of 317 patients, 158 cases had no preoperative biliary drainage, 115 received preoperative biliary drainage by percutaneous transhepatic choledochal drainage (PTCD), 44 received preoperative biliary drainage by endoscopic retrograde biliary drainage (ERBD). Observation indicators: (1) bile bacteria in different preoperative biliary drainage methods; (2) clinicopathological characteristics of patients with positive bile bacteria; (3) drug resistance of bile bacteria in different methods of preoperative biliary drainage. Measurement data with normal distribution were expressed as Mean± SD. Count data were expressed as absolute numbers or percen-tages, and comparison between groups was analyzed by the chi-square test. Bonferroni correction was used for pairwise comparison. The inspection level was 0.016 7 in the multiple comparison. Results:(1) Bile bacteria in different preoperative biliary drainage methods: of 317 patients, 116 cases were positive for bacterial culture, including 168 strains of 43 bacterial types. There were 46 strains from 36 patients without preoperative biliary drainage, 49 strains from 39 patients with preoperative PTCD and 73 strains from 41 patients with preoperative ERBD. ① The positive rate of bacteria for 317 patients was 36.59%(116/317). The positive rates of bacteria for patients without preoperative biliary drainage, patients with preoperative PTCD and patients with preoperative ERBD were 22.78%(36/158), 33.91%(39/115) and 93.18%(41/44). There was a significant difference in the positive rate of bacteria among the three groups ( χ2=74.066, P<0.05). There was no significant difference between patients with preoperative PTCD and patients without preoperative biliary drainage ( χ2=4.137, P>0.016 7), but there were significant differences between patients with pre-operative ERBD and patients without preoperative biliary drainage or patients with preoperative PTCD ( χ2=72.305, 44.718, P<0.016 7). ② The overall multiple bacterial rate was 36.21%(42/116). The multiple bacterial rates for patients without preoperative biliary drainage, patients with preoperative PTCD and patients with preoperative ERBD were 19.44%(7/36), 23.08%(9/39) and 63.41%(26/41). There was a significant difference in multiple bacterial rate among the three groups ( χ2=20.431, P<0.05). There was no significant difference between patients with PTCD and patients without preoperative biliary drainage ( χ2=0.147, P>0.016 7), but there were significant differences between patients with preoperative ERBD and patients without preoperative biliary drainage or patients with preoperative PTCD ( χ2=15.133, 13.215, P<0.016 7). ③ The overall prevalence rate of multi-drug resistant organism was 30.95%(52/168). The prevalence rates of multi-drug resistant organism for patients without preoperative biliary drainage, patients with preoperative PTCD and patients with preoperative ERBD group were 15.22%(7/46), 26.53%(13/49) and 43.84%(32/73). There was a significant difference in the prevalence rate of multi-drug resistant organism among the three groups ( χ2=11.447, P<0.05). There was no significant difference between patients with PTCD and patients without preoperative biliary drainage ( χ2=1.827, P>0.016 7). There was a significant difference between patients with preoperative ERBD and patients without preoperative biliary drainage ( χ2=10.497, P<0.016 7), but there was no significant difference between patients with preoperative ERBD and patients with preoperative PTCD ( χ2=3.772, P>0.016 7). (2) Clinicopatho-logical characteristics of patients with positive bile bacteria: age, the history of abdominal surgery, degree of jaundice and location of biliary obstruction of patients were not related to the positive rate of bacterial culture ( χ2=4.865, 1.423, 4.922, 0.030, P>0.05). (3) Drug resistance of bile bacteria in different methods of preoperative biliary drainage: for patients without preoperative biliary drainage, the drug resistance rate of Gram-positive bacteria to nitrofurantoin, linezolid and tigecycline was 0, and the drug resistance rate of Gram-negative bacteria to piperacillin/tazobactam, gentamicin, tobramycin, amikacin and imipenem was 0. For patients with PTCD, the drug resistance rate of Gram-positive bacteria to linezolid and tigecycline was 0. For patients with ERBD, the drug resistance rate of Gram-positive bacteria to linezolid and tigecycline was 0. In terms of Gram-positive bacteria, linezolid, tigecycline, vancomycin and nitrofurantoin were the top four antibiotics with the lowest resistance rate. In terms of Gram-negative bacteria, imipenem, piperacillin/tazobactam, amikacin and tobramycinn were the top four antibiotics with the lowest resistance rate. Seven strains of fungi showed no resistance to antifungal drugs. Conclusions:Patients with preoperative ERBD are more vulnerable to infectious complications, and more likely to form drug resistant organism and multi-drug resistant organism. For Gram-positive bacteria infection, linezolid, tigecycline and vancomycin can be used for treatment. For Gram-negative bacteria infection, imipenem, piperacillin/trzobactam, amikacin and tobramycin can be used for treatment.

Klebsiella pneumoniae and Escherichia coli are the two gram negative bacteria most resistant to antibiotics .The three popular gram negative bacilli in this study had the lowest resistance to imipenem/cilastatin ,piperacillin/tazobactam and amikacin .The three main gram positive bacteria were most sensitive to daptomycin ,linezolid and vancomycin .The total effective rate of anti-biotic treatments for post PTCD infections was 88 .1% .Conclusion Our hospital had an appropriate treatment plan with antibi-otics to control the infections post percutaneous transhepatic cholangio-drainage for malignant biliary obstruction .According to the results of drug sensitivity test ,ceftriaxone had high resistance rate .The outcome with ceftriaxone treatment was unsatis-factory .Clinical pharmacists should advise doctors to reduce the usage of ceftriaxone .Glycopeptide antibiotics can be used to control methicillin-resistant staphylococcus (MRS) gram positive bacteria .
RESUMO
Objective To explore the diagnostic value of contrast-enhanced ultrasonic intravenous imaging and cholangiography in the diagnosis of malignant jaundice obstructive. Methods Forty three patients who were diagnosed with malignant obstructive jaundice by contrast-enhanced computed tomography and contrast-enhanced computed magnetic resonance imaging were enrolled in this study. All of them underwent conventional ultrasound, IV-CEUS and IC-CEUS. According to the results of operation, the diagnosis accuracies were compared among conventional ultrasound, IV-CEUS, IC-CEUS and IV- CEUS combined with IC-CEUS. Results Diagnostic accuracy by the conventional ultrasound , IV-CEUS , IC-CEUS and IV- CEUS combined with IC-CEUS were 72.1%(31/43), 83.7%(36/43), 81.4%(35/43) and 93.0%(40/43), respectively. IV- CEUS combined with IC-CEUS was superior to the conventional ultrasound (P = 0.021). There were no significant differences when the conventional ultrasound was compared with IV-CEUS or IC-CEUS alone (P = 0.194 and 0.307). Conclusions Preoperative evaluation by IV- CEUS combined with IC-CEUS can elaborate the intra-cavitary and extra-cavitary changes of malignant obstructive jaundice. The diagnostic accuracy rate could be effectively improved by IV-CEUS combined with IC-CEUS, which can bring favorable clinical benefit.
RESUMO
Objective To discuss the nursing points for patients with malignant obstructive jaundice who are receiving biliary stenting combined with linear 125I seeds strand implantation. Methods A total of 41 patients with malignant obstructive jaundice were enrolled in this study. Biliary stenting combined with linear 125I seeds strand implantation was performed in all the 41 patients. Sufficient preoperative preparation and psychological intervention were carefully implemented. During the operation, active cooperation with the surgical procedures and close observation of patient’s vital signs as well as adverse reactions such as nausea and vomiting were strictly carried out. After the treatment the management of PTCD drainage tube, the protection of radiation and the early detection of complications were further emphasized. Results The technical success rate of biliary stenting together with linear 125I seeds strand implantation was 100%. The serum total bilirubin levels, determined at one week, one and 3 months after the treatment, were significantly decreased when compared with the preoperative data. Clinically, the jaundice basically subsided. Bile-cardiac reflex occurred in one case and displacement of PTCD drainage tube in 2 cases. Twelve patients developed chills and fever after operation. Acute renal insufficiency occurred in one patient, which was relieved after effective management. The median survival time was 10.9 months. Conclusion Careful and comprehensive preoperative preparation can ensure a successful operation. Intraoperative close observation of patient’s condition and skilled cooperation with the operator, and high quality postoperative nursing measures and close observation for early signs of complications are essential nursing points to ensure that the patients can safely get over the rehabilitation period.
RESUMO
Objective To summarize the clinical nursing experience for patients with malignant obstructive jaundice after receiving percutaneous biliary radiofrequency ablation (RFA) and stent implantation. Methods The postoperative nursing experience in 9 patients with malignant obstructive jaundice who received percutaneous biliary RFA together with stent implantation were retrospectively analyzed. The postoperative complications and the nursing intervention measures were analyzed and evaluated. Results Biliary RFA and subsequent stent implantation were successfully carried out in all 9 patients. After the procedure, biliary fistula occurred in one patient, biliary hemorrhage in 2 patients and biliary infection in 2 patients. The patient, who developed biliary fistula, died one week later, and the clinical conditions in the remaining 4 patients were improved after symptomatic treatment. During the follow-up period of one month, the patients were in good condition. Conclusion The main purpose of postoperative nursing for patients after receiving percutaneous biliary RFA is to prevent the occurrence of bile duct perforation, hemorrhage, infection, etc. It is very important to keep the patients under close observation and comprehensive nursing so as to make an early detection and timely treatment of such complications, thus to reduce the incidence of complications causing serious consequences as well as to promote an early recovery.
RESUMO
Objective To compare the effect of percutaneous intraluminal radiofrequency ablation ( RFA ) combined with biliary stenting and that of percutaneous transhepatic puncture combined with biliary stenting .Methods A total of 56 patients with unresectable malignant obstructive jaundice were reviewed retrospectively .Among them, 25 patients had received percutaneous intraluminal RFA combined with biliary stenting ( RFA group) while another 31 patients had been simultaneously selected for the simple biliary stent implantation ( stent group ) .The changes of the serum total bilirubin ( TB) and direct bilirubin ( DB) before and after 7-14 days of treatment , surgical complications , stent median patency and the median survival were observed.Follow-up information was obtained through telephone reviews or check-up records. Results The technical success rate was 100%.No procedure-related peritonitis or perforation occurred .There were respectively 3 cases with cholangeitis in RFA group and 3 in stent group.All the cases was controlled by effective clinical treatment.There was obvious statistically significant difference after treatment in TB and DB in the two groups (P<0.01, P<0.01).TB and DB fell by (149.05 ±110.71) and (96.93 ±69.12)μmol/L after 7-14 days in RFA group vs (151.40 ±94.47) and (94.21 ±67.36)μmol/L in stent group.The changes of the two groups were of no statistical significances .The stent patenmedian time was 122 ( 9 -550 ) and 157 ( 16 -510 ) d, while the median survival was 125(9-550) and 163 ( 16 -520 ) d.The difference was of no statistical significance .Conclusion Percutaneous intraluminal RFA combined with biliary stenting and percutaneous transhepatic puncture combined with biliary stenting are both safe and feasible therapeutic options for unresectable malignant obstructive jaundice .There is no statistically significant diffference between the two groups in the recent and long-term curative effects .
RESUMO
Objective To evaluate the patency rate of two types of metallic biliary stent in treating malignant biliary stenosis, and to discuss the patient’s survival rate. Methods A total of 126 patients with malignant biliary stenosis were treated with percutaneous implantation of biliary stent. The clinical data were retrospectively analyzed. A total of 167 metallic biliary stents were used in 126 patients. Ninety - two metal stents of mesh type were employed in 70 cases, while 75 metal stents of laser engraving type were adopted in 56 cases. After the treatment all patients were followed up, and the stent patency time as well as the median survival time was determined. The results were analyzed and compared between the two types of stents. Results Technical success rate was 100% (126/126). The median patency rate time of mesh type and laser type was 182 days and 196 days respectively, the patient’s median survival time of mesh type group and laser type group was 179 days and 186 days respectively. No statistically significant differences in the stent patency time and in the median survival time existed between the two groups (P > 0.05). Conclusion In treating malignant biliary obstruction with stenting, the mesh type stent and the laser type stent have quite same therapeutic effect. Therefore, in clinical practice the two types of stent can be replaced with each other to a certain degree.
