Characteristics and clinical outcomes of acute cholangitis in older patients

Advancements in Managing Choledocholithiasis and Acute Cholangitis in the Elderly: A Comprehensive Review

The increasing elderly population has led to a rising prevalence of choledocholithiasis and acute cholangitis, presenting unique diagnostic and therapeutic challenges owing to age-related physiological changes and multiple comorbidities. This comprehensive review synthesizes current evidence and recent advances in managing these conditions in elderly patients, with a particular focus on diagnostic innovations, therapeutic strategies, and perioperative optimization. Recent advances in diagnostic modalities, including enhanced imaging techniques and AI-assisted systems, have improved early detection accuracy, whereas minimally invasive interventions, particularly endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic common bile duct exploration (LCBDE), have demonstrated superior outcomes when combined with comprehensive perioperative care. The implementation of multidisciplinary approaches and personalized treatment strategies has significantly improved patient outcomes, with evidence supporting the critical role of early antibiotic intervention, careful surgical selection, and enhanced recovery protocols in reducing morbidity and mortality. The optimal management of elderly patients with choledocholithiasis and acute cholangitis requires a systematic, individualized approach incorporating advanced diagnostic techniques, minimally invasive interventions, and comprehensive perioperative care, while future research should focus on developing age-specific treatment algorithms and validating novel therapeutic approaches.

On-site ERCP availability and cholangitis outcomes: Retrospective cohort study

Background and study aims

Endoscopic retrograde cholangiopancreatography (ERCP) is important in acute cholangitis (AC) management but is not available at all hospitals. The association between on-site ERCP availability and cholangitis outcomes is unknown.

Patients and methods

We included adults diagnosed with AC at 27 hospitals in Ontario through the GEMINI network. We collected data on demographics, clinical and laboratory values, and interventions. The primary outcome was in-hospital mortality. Secondary outcomes were length of stay, intensive care unit (ICU) admission, readmission rates, and requirement for percutaneous or surgical decompression. We used multivariable regression analyses to assess the impact of on-site ERCP availability on the primary and secondary outcomes with adjustment for relevant variables.

Results

Our cohort included 4492 patients with a median age of 75. Patients at ERCP sites had higher unadjusted rates of undergoing ERCP (55.7% at ERCP sites, 40.8% at non-ERCP sites). Patients at ERCP sites compared with non-ERCP sites did not have significantly different in-hospital mortality (adjusted odds ratio [aOR] = 2.19, 95% confidence interval [CI] = 0.86-5.55). Compared with non-ERCP sites, patients at ERCP sites with underlying stricturing biliary disease or pancreaticobiliary malignancy (aOR = 1.94, 95% CI = 1.14-13.58) or severe cholangitis (aOR = 2.17, 95% CI = 1.17-4.02) had higher odds of in-hospital mortality. In a post-hoc propensity score-based analysis, there was no significant difference between patients at ERCP sites compared with those at non-ERCP sites for in-hospital mortality.

Conclusions

Patients at ERCP sites compared with non-ERCP sites did not have significantly different mortality. Subgroups of patients with underlying stricturing biliary disease or pancreaticobiliary malignancy and severe cholangitis, who have higher mortality at ERCP sites, warrant further study.

Clinical Features and Prognosis of Acute Cholangitis in Octogenarians: A Prospective Comparative Study

Background: The data on acute cholangitis in the octogenarian population are very limited. This study aimed to examine the clinical characteristics of acute cholangitis and complications related to endoscopic retrograde cholangiopancreatography (ERCP) in octogenarians. Materials and Methods: This study was conducted prospectively between July 2022 and December 2023 and included 250 patients aged 65 years and older. Patients eligible for the study were divided into two groups: those aged ≥80 years (octogenarian) and those aged 65-79 years (non-octogenarian). These two groups were compared in terms of the clinical characteristics of cholangitis and ERCP-related complications. In addition, factors associated with in-hospital mortality were evaluated. Results: Out of 250 patients, 87 (34.8%) were octogenarians and 163 (65.2%) were non-octogenarians. The median age was 76 (69-82) years. Although the octogenarian group had higher rates of severe illness and intensive care unit admissions (p < 0.001 and p = 0.002, respectively), there were no significant differences in in-hospital mortality (p = 0.359) or ERCP-related complications (p = 0.417). Malignant etiology (odds ratio [OR]: 5.68, 95% confidence interval [CI]: 2.11-15.3), hypoalbuminemia (OR 0.18, 95% CI 0.07-0.45), and qSOFA score ≥ 2 (OR: 6.5, 95% CI: 1.7-24.5) were independent risk factors for in-hospital mortality. Conclusions: Being over 80 years old is not an indicator of poor outcomes, and ERCP can be safely performed on these patients. However, elderly patients with hypoalbuminemia, malignant etiology, or a qSOFA score of ≥2 should be closely monitored, regardless of their age.

The Comparison of Clinical Outcomes in Elderly (≥75 Years) and Non-Elderly (<75 Years) Patients with Acute Cholangitis Due to Choledocholithiasis

Background and Objectives: Acute cholangitis may be fatal, particularly in elderly patients. According to the Tokyo Guidelines 2018, those aged ≥75 years are classified as moderate (Grade II) severity. However, it has not been established whether age itself is the deciding factor of poor outcomes. We studied the impact of old age (≥75 years) on the mortality and morbidity of acute cholangitis due to choledocholithiasis. Materials and Methods: We retrospectively examined 260 patients with calculous acute cholangitis who had undergone biliary drainage. Patients were divided into two groups: elderly (≥75 years) and non-elderly (<75 years). We aimed to compare organ dysfunction, in-hospital mortality, intensive care unit (ICU) hospitalization, and the severity of acute cholangitis. Results: Of 260 patients, 134 (51.5%) were in the elderly group and 126 (48.5%) were in the non-elderly group. The mean age was 72.3 ± 14.4 years, and 152 (58.5%) were men. The elderly patients showed a higher incidence of shock (12.7% vs. 4.8%, p = 0.029), respiratory dysfunction (7.5% vs. 0%, p = 0.002), and renal dysfunction (8.2% vs. 0.8%, p = 0.006) than the non-elderly patients. The overall in-hospital mortality rate was 2.7%, with no significant differences between the elderly and the non-elderly (4.5% vs. 0.8%, p = 0.121). The incidence of severe acute cholangitis was significantly higher in the elderly group (26.9% vs. 9.5%, p < 0.001). However, there was no significant difference in the rates of ICU hospitalization (9.7% vs. 4%, p = 0.088) and lengths of hospital stay (LOS) (8.3 d vs. 7.1 d, p = 0.086). Conclusions: No difference was observed in the in-hospital mortality, ICU hospitalization, or LOS between the elderly (≥75 years) and the non-elderly (<75 years) with calculous acute cholangitis. However, severe acute cholangitis was significantly more frequent in elderly patients.
