Abstract
Introduction Biliary Infection in patients is a common and important phenomenon resulting in severe complications and high morbidity, while the distributions and drug resistance profiles of biliary bacteria and related risk factors are dynamic. This study explored the characteristics of and risk factors for biliary infection to promote the rational use of antibiotics in clinically. Methods Bacterial identification and drug susceptibility testing were completed using the Vitek 2 Compact analysis system. The distribution and antibiotic-resistant characteristics of 3,490 strains of biliary bacteria in patients at Nankai Hospital from 2019 to 2021 were analyzed using Whonet 5.6 and SPSS 26.0 software. We then retrospectively analyzed the clinical data and risk factors associated with 2,340 strains of Gram-negative bacilli, which were divided into multidrug-resistant bacteria (1,508 cases) and non-multidrug-resistant bacteria (832 cases) by a multivariate Cox regression model. Results and discussion A total of 3,490 pathogenic bacterial strains were isolated from bile samples, including 2,340 (67.05%) Gram-negative strains, 1,029 (29.48%) Gram-positive strains, and 109 (4.56%) fungal strains. The top five pathogenic bacteria were Escherichia coli, Klebsiella pneumoniae, Enterococcus faecium, Enterococcus faecalis, and Pseudomonas aeruginosa. The rate of Escherichia coli resistance to ciprofloxacin increased (p < 0.05), while the resistance to amikacin decreased (p < 0.05). The resistance of Klebsiella pneumoniae to cephalosporins, carbapenems, β-lactamase inhibitors, cephalases, aminoglycosides, and quinolones increased (p < 0.05), and the resistance of Pseudomonas aeruginosa to piperacillin, piperacillin/tazobactam, ticacillin/clavulanic acid, and amicacin declined significantly (p < 0.05). The resistance of Enterococcus faecium to tetracycline increased by year (p < 0.05), and the resistance of Enterococcus faecalis to erythromycin and high-concentration gentamicin declined (p < 0.05). Multivariate logistic regression analysis suggested that the administration of third- or fourth-generation cephalosporins was an independent risk factor for biliary infection. In summary, Gram-negative bacilli were the most common pathogenic bacteria isolated from biliary infection patients, especially Escherichia coli, and the rates and patterns of drug resistance were high and in constant flux; therefore, rational antimicrobial drug use should be carried out considering risk factors.

[PMID: 38655140 PMCID: PMC11035768 DOI: 10.3389/fonc.2024.1370383] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Accepted: 03/18/2024] [Indexed: 04/26/2024] Open
Abstract
Background Currently, percutaneous transhepatic cholangial drainage (PTCD) and endoscopic retrograde cholangiopancreatography (ERCP) are commonly employed in clinical practice to alleviate malignant obstructive jaundice (MOJ). Nevertheless, there lacks a consensus regarding the superiority of either method in terms of efficacy and safety. Aim To conduct a systematic evaluation of the effectiveness and safety of PTCD and ERCP in treating MOJ, and to compare the therapeutic outcomes and safety profiles of these two procedures. Methods CNKI, VIP, Wanfang, CBM, PubMed, Web of Science, Embase, The Cochrane Library, and other databases were searched for randomized controlled trials (RCTs) on the use of PTCD or ERCP for MOJ. The search period was from the establishment of the databases to July 2023. After quality assessment and data extraction from the included studies, Meta-analysis was performed using RevMan5.3 software. Results A total of 21 RCTs involving 1,693 patients were included. Meta-analysis revealed that there was no significant difference in the surgical success rate between the two groups for patients with low biliary obstruction (P=0.81). For patients with high biliary obstruction, the surgical success rate of the PTCD group was higher than that of the ERCP group (P < 0.0001), and the overall surgical success rate of the PTCD group was also higher than that of the ERCP group (P = 0.008). For patients with low biliary obstruction, the rate of jaundice relief (P < 0.00001) and the clinical efficacy (P = 0.0005) were better in the ERCP group, while for patients with high biliary obstruction, the rate of jaundice relief (P < 0.00001) and the clinical efficacy (P = 0.003) were better in the PTCD group. There was no significant difference in the overall jaundice remission rate and clinical efficacy between the two groups (P = 0.77, 0.53). There was no significant difference in the reduction of ALT, TBIL, and DBIL before and after surgery and the incidence of postoperative complications between the two groups (P > 0.05). Conclusion Both PTCD and ERCP can efficiently alleviate biliary obstruction and enhance liver function. ERCP is effective in treating low biliary obstruction, while PTCD is more advantageous in treating high biliary obstruction.

Risk factors analyses associated with postoperative infection in choledochoscopy for intrahepatic bile duct stones (IHDs): a single-center retrospective study in real-world setting. Surg Endosc 2024; 38:2050-2061.

Abstract
BACKGROUND Choledochoscopy is a highly effective approach for managing intrahepatic bile duct stones (IHDs). However, postoperative infection is a common complication that significantly impacts treatment outcomes. Despite its clinical relevance, the risk factors associated with this procedure remain largely unexplored. METHODS This study focused on a consecutive cohort of patients who underwent choledochoscopy for IHDs at our institution between January 2016 and December 2022. The primary objective was to analyze the relationship between various clinical factors and postoperative infection, and to compare the postoperative infection of different choledochoscopic procedures. RESULTS The study cohort consisted of 126 patients, with 60 individuals (47.6%) experiencing postoperative infection. Notably, preoperative biliary obstruction (odds ratio [OR] 1.861; 95% confidence interval [CI] 1.314-8.699; p = 0.010) and operation time (OR 4.414; 95% CI 1.635-12.376; p = 0.004) were identified as risk factors for postoperative infection. Additionally, biliary tract infections (60.00%) were primarily responsible for postoperative infection, with Escherichia coli (47.22%) being the predominant bacterial strain identified in bile cultures. Furthermore, biliary tract obstruction (OR 4.563; 95% CI 1.554-13.401; p = 0.006) and body mass index (BMI) (OR 1.186; 95% CI 1.015-1.386; p = 0.031) were determined to be independent risk factors for postoperative biliary tract infection. CONCLUSIONS The occurrence of postoperative infection in patients undergoing choledochoscopy was primarily associated with the duration of the operation and the presence of preoperative biliary obstruction.

Abstract
Purpose Malignant biliary obstruction (MBO) is common in patients with advanced malignant tumors, leading to poor prognosis and hindering antitumor therapy. The purpose of our study was to assess the survival outcomes for patients under therapy after percutaneous transhepatic biliary drainage (PTBD) and identify prognostic factors associated with survival in patients with MBO. Methods From July 2010 to February 2021, 269 patients with MBO secondary to malignant tumor were divided into two groups (functional success and non-functional success). Survival time and prognostic factors were analyzed by Kaplan-Meier curves and the Cox model. Results The overall median survival time after PTBD was 4.6 months (95 % IC:3.9-5.3). The 3- and 6-month survival rates were 68.0 % and 38.7 %, respectively. The median survival improved from 3.2 months to 8.4 months when the procedure achieved functional success. Multivariate analysis demonstrated that functionally successful drainage and antitumor treatment after PTBD were independent positive prognostic factors, but the total bilirubin after drainage and tumor size were independent negative predictive values. Conclusions Functionally successful drainage could prolong survival time in patients with malignant biliary obstruction. Palliative care after drainage can prolong patient survival and improve their quality of life.

Abstract
The human gastrointestinal tract (GIT) is home to an abundance of diverse microorganisms, and the balance of this microbiome plays a vital role in maintaining a healthy GIT. The obstruction of the flow of bile into the duodenum, resulting in obstructive jaundice (OJ), has a major impact on the health of the affected individual. This study sought to identify changes in the duodenal microbiota in South African patients with OJ compared to those without this disorder. Mucosal biopsies were taken from the duodenum of nineteen jaundiced patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) and nineteen control participants (non-jaundiced patients) undergoing gastroscopy. DNA extracted from the samples was subjected to 16S rRNA amplicon sequencing using the Ion S5 TM sequencing platform. Diversity metrics and statistical correlation analyses with the clinical data were performed to compare duodenal microbial communities in both groups. Differences in the mean distribution of the microbial communities in the jaundiced and non-jaundiced samples were observed; however, this difference did not reach statistical significance. Of note, there was a statistically significant difference between the mean distributions of bacteria comparing jaundiced patients with cholangitis to those without (p = 0.0026). On further subset analysis, a significant difference was observed between patients with benign (Cholelithiasis) and malignant disease, namely, head of pancreas (HOP) mass (p = 0.01). Beta diversity analyses further revealed a significant difference between patients with stone and non-stone related disease when factoring in the Campylobacter-Like Organisms (CLO) test status (p = 0.048). This study demonstrated a shift in the microbiota in jaundiced patients, especially considering some underlying conditions of the upper GI tract. Future studies should aim to verify these findings in a larger cohort.
