Epidemiological profile, referral routes and diagnostic accuracy of cases of acute cholangitis among individuals with obstructive jaundice admitted to a tertiary-level university hospital: a cross-sectional study

Perceptions of transitional care services among patients with percutaneous transhepatic biliary drainage and multicentre health professionals: A qualitative study

BACKGROUND

Patients with percutaneous transhepatic biliary drainage (PTBD) need regular drainage tube care after discharge, and transitional care can help solve this problem. However, few studies have focused on the quality of transitional care, the perceptions of patients with drainage tubes after discharge and those of healthcare professionals.

AIM

This study is aimed at exploring the real experience and perceptions of transitional care services among healthcare professionals and PTBD patients who have been discharged with tubes and at providing references for future transitional care service development.

DESIGN

The study uses a qualitative descriptive design. The reporting method followed Consolidated Criteria for Reporting Qualitative Research guidelines.

METHODS

Semistructured interviews were conducted with PTBD patients who had been discharged with tubes and multicentre healthcare professionals using the purpose sampling method. The thematic analysis method was used for analysis.

RESULTS

Thirteen PTBD patients from one hospital and 12 healthcare professionals from three hospitals were interviewed. The analysis of the patient interview data revealed three themes, namely, recognition of the value of transitional care services, patients have some unmet needs and perception of transitional care service pathways. Six subthemes were also identified. The analysis of the interview data of healthcare professionals revealed two themes, namely, harvest and challenges in transitional care services work and expectations for future development of transitional care services. Four subthemes were also identified.

CONCLUSIONS

The transitional care of discharged patients with PTBD tubes deserves the attention of clinical workers, and a series of measures should be taken to improve transitional care services.

PATIENT/PUBLIC CONTRIBUTION

Patients were involved in the formulation of interview questions for this study, and during the interviews, patients presented their suggestions for transitional care services. Healthcare professionals participated in this study as interviewees, and no members of the public were involved in this study.

Comparative Analysis of Antibiotic Resistance in Acute Cholangitis Patients with Stent Placement and Sphincterotomy Interventions

In response to rising concerns over multidrug resistance patterns in acute cholangitis patients, this retrospective study was conducted at the Emergency County Hospital Timisoara, Romania, encompassing patients treated between August 2020 and August 2023. The study aimed to investigate the influence of prior interventions, specifically sphincterotomy (with or without stent placement), on the current clinical and microbiological profiles of acute cholangitis patients. By differentiating between patients with a history of sphincterotomy and the endoscopic retrograde cholangiopancreatography (ERCP)-naïve, we assessed the resistance of bacterial strains to antibiotics by the Tokyo Guidelines 2018, using bile cultures from 488 patients. The study identified various multidrug-resistant organisms, with a total multidrug resistance incidence of 19.9%. Significant variations were observed in the distribution of specific microorganisms and resistance patterns across different intervention groups. Patients with previous interventions, particularly those with both sphincterotomy and stent, exhibited elevated white blood cells (WBC) and C-reactive protein (CRP) levels in comparison to their ERCP-naïve counterparts. This group also presented a striking prevalence of two bacteria in their bile cultures at 50.0%, compared to 16.1% in ERCP-naïve individuals. Regarding multidrug resistance, the prior sphincterotomy with stent placement had a prevalence of 50.0%. The presence of ESBL bacteria was also significantly higher in the same group at 28.7%, contrasting with the 8.9% in ERCP-naïve patients. Additionally, the same group had a higher burden of Klebsiella spp. infections, at 37.2%, and Enterococcus spp. at 43.6%. On the antibiotic resistance front, disparities persisted. Piperacillin/Tazobactam resistance was notably more rampant in patients with a previous sphincterotomy and stent, registering at 25.5% against 11.1% in the ERCP-naïve group. This study underscores a substantial discrepancy in multidrug resistance patterns and antibiotic resistance among acute cholangitis patients with previous manipulation of the bile ducts, without expressing significant differences by the type of stent used.

Relationships of hepatic histopathological findings and bile microbiological aspects with bile duct injury repair surgical outcomes: A historical cohort

Backgrounds/Aims

To analyze relationships of hepatic histopathological findings and bile microbiological profiles with perioperative outcomes and risk of late biliary stricture in individuals undergoing surgical bile duct injury (BDI) repair.

Methods

A historical cohort study was carried out at a tertiary university hospital. Fifty-six individuals who underwent surgical BDI repair from 2014-2018 with a minimal follow-up of 24 months were enrolled. Liver biopsies were performed to analyze histopathology. Bile samples were collected during repair procedures. Hepatic histopathological findings and bile microbiological profiles were then correlated with perioperative and late outcomes through uni- and multi-variate analyses.

Results

Forty-three individuals (76.8%) were females and average age was 47.2 ± 13.2 years; mean follow-up was 38.1 ± 18.6 months. The commonest histopathological finding was hepatic fibrosis (87.5%). Bile cultures were positive in 53.5%. The main surgical technique was Roux-en-Y hepaticojejunostomy (96.4%). Overall morbidity was 35.7%. In univariate analysis, liver fibrosis correlated with the duration of the operation (R = 0.3; p = 0.02). In multivariate analysis, fibrosis (R = 0.36; p = 0.02) and cholestasis (R = 0.34; p = 0.02) independently correlated with operative time. Strasberg classification independently correlated with estimated bleeding (R = 0.31; p = 0.049). The time elapsed between primary cholecystectomy and BDI repair correlated with hepatic fibrosis (R = 0.4; p = 0.01).

Conclusions

Bacterial contamination of bile was observed in most cases. The degree of fibrosis and cholestasis correlated with operative time. The waiting time for definitive repair correlated with the severity of liver fibrosis.

Comparative Study of the Results of Operations in Patients with Tumor and Non-Tumor Obstructive Jaundice Who Received and Did Not Receive Antioxidant Therapy for the Correction of Endotoxemia, Glycolysis, and Oxidative Stress

Purpose: To compare the results of surgical treatment and changes in biomarkers of cholestasis, endotoxicosis, cytolysis, lipid peroxidation, glycolysis disorders, and inflammation in patients with benign and malignant obstructive jaundice (OJ) in patients receiving and not receiving antioxidant pharmacotherapy (AOT). Patients and methods: The study included 113 patients (aged 21–90 years; 47 males and 66 females) who received surgical intervention for OJ due to non-malignant (71%) or malignant tumor (29%) etiologies. Patients were divided into two groups: Group I (n = 61) who did not receive AOT and Group II (n = 51) who received AOT (succinate-containing drug Reamberin) as part of detoxification infusion therapy. The surgical approach and scope of interventions in both groups were identical. Dynamic indicators of endotoxicosis, cholestasis, and cytolysis (total, direct, and indirect bilirubin, alanine aminotransferase [ALT], aspartate aminotransferase [AST], alkaline phosphatase [AP] and gamma-glutamyltransferase [GGT]), kidney function (urea), lipid peroxidation (malonic dialdehyde, MDA), inflammation (leukocytosis), and glycolysis disorders (lactate dehydrogenase (LDH), glucose) were evaluated. Results: Tumor jaundice, unlike non-tumor jaundice, persisted and was characterized by a more severe course, a higher level of hyperbilirubinemia, and lipid peroxidation. The prognostic value of the direct (and total) bilirubin, MDA, glycemia, and leukocytosis levels on the day of hospitalization, which increased significantly in severe jaundice and, especially, in deceased patients, was established. Decompression interventions significantly reduced levels of markers of liver failure, cytolysis, cholestasis, and lipid peroxidation on day 3 after decompression by 1.5–3 times from initial levels; this is better achieved in non-tumor OJ. However, 8 days after decompression, most patients did not normalize the parameters studied in both groups. AOT favorably influenced the dynamics (on day 8 after decompression) of total and direct bilirubin, ALT, AST, MDA, and leukocytosis in non-tumor jaundice, as well as the dynamics of direct bilirubin, AST, MDA, glucose, and LDH in tumor jaundice. Clinically, in the AOT group, a two-fold reduction in the operative and non-operative complications was recorded (from 23% to 11.5%), a reduction in the duration of biliary drainage by 30%, the length of stay in intensive care units was reduced by 5 days, and even hospital mortality decreased, especially in malignancy-induced OJ. Conclusion: A mechanism for the development of liver failure in OJ is oxidative stress with the appearance of enhanced lipid peroxidation and accompanied by hepatocyte necrosis. Inclusion of AOT in perioperative treatment in these patients improves treatment outcomes.

Effect of transient obstructive cholestasis on liver histology: a cross-sectional study

BACKGROUND

The role of transient obstructive cholestasis on liver histology remains undetermined.

OBJECTIVE

To investigate whether transient cholestasis impairs liver histology.

DESIGN AND SETTING

Cross-sectional study at a public university hospital (UNICAMP), Brazil.

METHODS

169 individuals undergoing cholecystectomy, with or without cholestasis. were enrolled. Histopathological findings were correlated with clinical and biochemical characteristics.

RESULTS

Biliary hepatopathy was more frequent in individuals with resolved cholestasis than in those with active obstruction or no jaundice (P < 0.01), as also were fibrosis and ductular proliferation (P = 0.02). Cholestasis was commoner in individuals with resolved obstruction than in those with no history (P < 0.01) or active cholestasis (P < 0.05). Biliary hepatopathy was associated with longer duration of cholestasis (P < 0.001) and higher bilirubin levels (P = 0.02) in individuals with active obstruction; with lower body mass index (P = 0.02) and longer cholestasis (P < 0.001) in individuals with resolved obstruction; and with longer cholestasis (P < 0.001) and longer interval between endoscopic retrograde cholangiopancreatography and surgery (P = 0.03) overall. In individuals with active obstruction, duration of cholestasis (R = 0.7; P < 0.001) and bilirubin levels (R = 0.6; P = 0.004) were independently correlated with cholestasis severity. Duration of cholestasis (R = 0.7; P < 0.001) was independently correlated with ductular proliferation severity.

CONCLUSIONS

Transient cholestasis was associated with significant histopathological changes, even after its resolution. Longer duration of obstruction correlated with greater severity of histopathological changes, especially cholestasis and ductular proliferation. This emphasizes the need for early treatment of obstructive cholestasis.
