Old age is associated with increased severity of complications in endoscopic biliary stone removal

Safety, efficacy and post-endoscopic retrograde cholangiopancreatography survival in nonagenarians: a retrospective cohort study

BACKGROUND

Increasing numbers of older patients with pancreatobiliary disease are undergoing endoscopic retrograde cholangiopancreatography (ERCP). Older patients may be at higher risk of ERCP-related adverse events due to their age and comorbidities; however, data are sparse.

AIMS

This study aimed to evaluate long-term mortality, procedural outcomes and safety of ERCP in nonagenarians.

METHODS

We retrospectively evaluated consecutive patients aged ≥90 years who underwent ERCP at a tertiary hospital over 12 years. The primary outcome was survival. Secondary outcomes included procedural success and adverse events. Logistic regression was used to analyse procedural outcomes, and factors predictive of survival were identified using a Cox proportional hazard model visualised by Kaplan-Meier plot.

RESULTS

A total of 159 consecutive ERCPs were performed in 115 nonagenarian patients. The mean age of the cohort was 92.3 (standard deviation ± 2.1) years. Choledocholithiasis (78.6%) was the most common indication, followed by malignant biliary obstruction (MBO, 18.9%) and bile leak (2.5%). Survival following ERCP for MBO at 30 days, 3 months and 1 year was 78%, 52% and 9%, respectively, compared to 98%, 94% and 89% for choledocholithiasis (P < 0.001). Procedural success was achieved in 91% of ERCPs (benign or malignant). ERCPs performed for MBO were more likely to fail (P < 0.001). Adverse events occurred in 5% of procedures.

CONCLUSION

Therapeutic ERCP in select nonagenarians is a clinically relevant intervention for both malignant and benign pathology. Age does not constitute a barrier to the performance of ERCP in appropriately selected patients. Nonagenarians may be counselled for a success and adverse event rate equivocal to younger populations.

Safety of Nonagenarians Receiving Therapeutic ERCP, Single Center Experience

(1) Background: The complication rates for nonagenarians receiving therapeutic endoscopic retrograde cholangiopancreatography (ERCP) remain poorly understood. We aimed to determine whether nonagenarians were at an increased risk of ERCP-related complications. (2) Methods: We performed a retrospective study on therapeutic ERCP in nonagenarians from 2011 to 2016 at Taichung Veterans General Hospital. A control group comprising patients aged 65 to 89 years was used to compare demographic data and the outcomes of therapeutic ERCP with the nonagenarians. The risk factors for complications were determined by logistic regression model. (3) Results: There were 35 nonagenarians and 111 patients in the control group. Overall, complication rates were not statistically different between the two groups. However, advanced age was an independent predictor of complications in the multivariate analysis (odds ratio [OR] = 1.06; 95% confidence interval [CI] = 1.01-1.12; p = 0.049). End stage renal disease (ESRD) was another independent predictor of complications (OR = 4.87; 95% CI = 1.11-21.36; p = 0.036). Post-ERCP pancreatitis and bleeding were more common in ESRD patients than patients without ESRD. (4) Conclusions: Although nonagenarians receiving ERCP did not have more complications compared to elderly patients younger than 90 years, advanced age and comorbidity still affect the outcome of therapeutic ERCP in the elderly patients.

Increased severity of complications after therapeutic ERCP in geriatric patients with chronic pancreatitis: An observational study

Studies of therapeutic endoscopic retrograde cholangiopancreatography (ERCP) in geriatric patients have mainly examined patients with biliary diseases, rather than chronic pancreatitis (CP). This study aimed to evaluate the safety and success rate of therapeutic ERCP in geriatric patients with CP. The medical records of patients with CP aged over 65 years (group A) were retrospectively collected in a tertiary hospital from January 2013 to December 2018. Sex-matched CP patients under 65 years (group B) were randomly selected into the control group (matching ratio = 1:2). The success rate and the complication rate of therapeutic ERCP in 2 groups were compared. The risk factors for post-ERCP pancreatitis were investigated by univariate and multivariate analyses. A total of 268 ERCPs were performed in 179 patients of group A and 612 ERCPs in 358 patients of group B. The success rate of ERCP in group A was similar to that of group B (92.16% vs 92.32%; P = .936). The overall incidence of post-ERCP complications was 7.09% (19/268) and 5.72% (35/612) in group A and B, respectively (P = .436). However, geriatric patients had a significantly increased occurrence of moderate to severe complications (2.61% vs 0.16%; P = .002). Female gender (odds ratio [OR] = 3.40; P = .046), pancreas divisum (OR = 7.15; P = .049), dorsal pancreatogram (OR = 7.40; P = .010), and lithotripsy (OR = 0.15; P = .016) were significantly associated with risk of post-ERCP pancreatitis in geriatric patients. Therapeutic ERCP is safe and feasible in elderly patients with CP. However, occurrence of moderate to severe complications after ERCP increased in geriatric patients.

Does Endoscopic Retrograde Cholangiopancreatography Carry Higher Risk for Patients 90 Years and Older? A Single-Institution Retrospective Study

BACKGROUND Endoscopic retrograde cholangiography (ERCP) for patients aged ≥90 years is often required. The safety of ERCP for super-elderly patients is a major concern for gastrointestinal endoscopists. We retrospectively examined the safety of ERCP for super-elderly patients by comparison with patients in their 70s. MATERIAL AND METHODS We reviewed 66 patients aged ≥90 years (Group A) and 43 patients in their 70s (Group B) who underwent ERCP in our institution from January 2012 to October 2019. Data were collected on patients' backgrounds, corresponding procedures, and clinical outcomes, including adverse events. RESULTS Patients in Group A (mean age: 92.3±2.1 years) had significantly poorer performance status (median: 3 vs. 0; P<0.001) and American Society of Anesthesiologists classification (median: III vs. II; P<0.001) when compared to Group B (mean age: 75.1±2.7 years). Underlying cardiovascular, cerebrovascular, renal, and orthopedic comorbidity occurrence was significantly higher in Group A than in Group B (87.88% vs. 67.44%; P=0.0094). Group A comprised more patients with benign disease than Group B (90.91% vs. 76.74%; P=0.040). Group B comprised more patients with malignant disease (31.82% vs. 53.54%; P=0.041). Emergency ERCP was higher in Group A than in Group B (71.70% vs. 29.73%; P<0.0001). No significant between-group differences in adverse events (15.15% vs. 11.63%; P=0.602) and mortality rate (1.52% vs. 2.33%; P=0.758) were noted. CONCLUSIONS Indications for ERCP should not be determined simply based on the super-elderly age of patients. ERCP may not necessarily carry higher risks if endoscopists practice maximal caution against gastrointestinal perforation.

Safety and Efficacy of Endoscopic Removal of Common Bile Duct Stones in Elderly Patients ≥90 Years of Age

Objective We examined the safety and efficacy of endoscopic stone removal for choledocholithiasis in elderly patients ≥90 years of age with native papilla and compared the outcomes with those in patients 75-89 years of age. Methods This multicenter retrospective study included 569 patients 75-89 years of age and 126 patients ≥90 years of age who had native papilla and underwent therapeutic endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis at 3 institutions in Japan between April 2012 and March 2018. The main outcomes assessed were the incidence of post-ERCP complications during hospitalization and outcomes of ERCP in patients ≥90 years of age. Results Biliary cannulation and subsequent endoscopic sphincterotomy, endoscopic balloon dilation, and endoscopic large balloon dilation were successful in 97.7% of patients 75-89 years of age and in 98.4% of patients ≥90 years of age. There was no significant difference in the incidence of post-ERCP complications between patients 75-89 years of age and those ≥90 years of age (7.7% vs. 9.5%, respectively; p=0.47). Although the rate of use of mechanical lithotripter was not significantly different, the rate of complete stone removal in patients ≥90 years of age was lower than that in patients 75-89 years of age (81.0% vs. 94.9%, respectively; p<0.001). In all cases with incomplete stone removal in both groups, permanent biliary stent placement was successful. Conclusion ERCP for choledocholithiasis in elderly patients ≥90 years of age is a safe and effective procedure; however, endoscopists should select appropriate strategies after considering each patient's medical condition and background.

Risk factors of adverse events in endoscopic retrograde cholangiopancreatography for patients aged ≥85 years

AIM

Little is known about the factors that contribute to the occurrence of adverse events in endoscopic retrograde cholangiopancreatography (ERCP) for people aged ≥85 years and safety for the super-old. Therefore, we decided to identify these factors and to examine whether ERCP is safe in the super-old.

METHODS

This was a single-center retrospective study. A total of 137 patients aged ≥85 years who underwent therapeutic ERCP at Chiba University Hospital from January 2012 to March 2017 were retrospectively reviewed.

RESULTS

Four cases of Billroth II reconstruction and two cases of gastrectomy with Roux-en-Y reconstruction were excluded, and 131cases in total were examined in the present study. A total of 10 and 121 cases with and without adverse events, respectively, were present. Using univariate analysis, factors significantly contributing to the occurrence of adverse events in therapeutic ERCP were identified as aged ≥90 years (P = 0.0096), duodenal papilla cancer (P = 0.0012), gallbladder carcinoma (P = 0.023), and biliary metal stenting (P = 0.040). In multivariate analysis, only ≥90 years-of-age was a significant factor (P = 0.049). In addition, comparison between 25 cases of the super-old and 106 cases aged 85-89 years was carried out. In the super-old group, the average value of the American Society of Anesthesiologists physical status classification and Charlson's Comorbidity Index were significantly better than those in 85-89-year-olds (P = 0.0035 and P < 0.0001, respectively).

CONCLUSIONS

Although the super-old group had fewer comorbid diseases, they had significantly increased adverse events compared with patients aged 85-89 years. Geriatr Gerontol Int 2018; 18: 1038-1045.

Endoscopic retrograde cholangiopancreatography in the elderly: results of a retrospective study and a geriatricians' point of view

Background

The incidence of biliary tract pathology is growing with an age-related trend, and progresses as the population ages. Endoscopic Retrograde Cholangiopancreatography (ERCP) represents the gold standard for treatment in these cases, but evidence about its safety in the elderly is still debated.

Methods

We retrospectively analyzed the clinical records of all patients aged ≥65 undergoing ERCP between July 2013 and July 2015. Of 387 ERCP cases, 363 (~ 94%) were completed entirely. The mean age of the study population (n = 363) was 79.9 years old (range 70–95), with 190 subjects aged 70–79 and 173 older than 80. We recorded demographics, Charlson Comorbidity index (CCI), American Society of Anesthesiologists (ASA) physical status classification score, indication for the use of the ERCP procedure, and clinical outcomes. Then, we tested all variables to identify the potential risk factors for complications associated with the procedure.

Results

The older group (those ≥80 years old) showed significantly more patients with ASA Classes III-IV than the younger one (those ≤79 years old). Interestingly, the CCI was higher in the younger group (p = 0.009). The overall complication rate was 17.3% without inter-group differences. Older age, sex, CCI and intra-ERCP procedures were not related to a higher risk of complications, and the multivariate regression did not identify any of the considered variables to be an independent risk factor for complications.

Conclusion

ERCP appears as safe in the patients aged 80 years and older, as it is in those aged 70–79 years old in our study, however, a selection bias may affect these findings. A study including a comprehensive geriatric assessment will contribute to shedding light on this issue.

Increased risk and severity of ERCP-related complications associated with asymptomatic common bile duct stones

BACKGROUND AND STUDY AIMS

 Endoscopic removal of asymptomatic common bile duct stones (CBDS) is generally recommended. Although many reports have described the risk of complications in endoscopic retrograde cholangiopancreatography (ERCP), no studies have addressed this problem in the context of asymptomatic CBDS. This study examines the risk of complications arising in ERCP for asymptomatic CBDS.

PATIENTS AND METHODS

 This retrospective study included 425 patients with naive papilla who underwent therapeutic ERCP for choledocholithiasis at 2 institutions in Japan for 2 years. The risk of complications was examined in patients who were divided into the asymptomatic and symptomatic CBDS groups. We used propensity score analysis to adjust for confounding effects.

RESULTS

 Complications were observed in 32 (7.5 %) of the 425 patients. Of the 358 patients with symptomatic CBDS, 14 patients (3.9 %) had complications. In contrast, of the 67 patients with asymptomatic CBDS, 18 patients (26.9 %) had complications. Propensity score analysis revealed that asymptomatic CBDS was a significant risk factor, with a significantly higher incidence of complications compared with symptomatic CBDS (odds ratio, 5.3). Moderate to severe complications were observed in 15 of 18 patients (83.3 %) in the asymptomatic CBDS group, with significantly more moderate to severe complications than those in the symptomatic CBDS (odds ratio, 6.7).

CONCLUSIONS

 Asymptomatic CBDS carried a high risk of ERCP-related complications, and these were often more severe. In asymptomatic CBDS, endoscopic treatment should be carefully performed after considering the patient's background, and detailed explanation of its possible complications should be given to patients in advance.

Urgent ERCP for acute cholangitis reduces mortality and hospital stay in elderly and very elderly patients

BACKGROUND

Acute cholangitis in old people is a cause of mortality and prolonged hospital stay. We evaluated the effects of methods and timing of biliary drainage on the outcomes of acute cholangitis in elderly and very elderly patients.

METHODS

We analyzed 331 patients who were older than 75 years and were diagnosed with acute calculous cholangitis. They were admitted to our hospital from 2009 to 2014. Patients' demographics, severity grading, methods and timing of biliary drainage, mortality, and hospital stay were retrospectively obtained from medical records. Clinical parameters and outcomes were compared between elderly (75-80 years, n=156) and very elderly (≥81 years, n=175) patients. We analyzed the effects of methods [none, endoscopic retrograde cholangiopancreatography (ERCP), percutaneous transhepatic biliary drainage, or failure] and timing (urgent or early) of biliary drainage on mortality and hospital stay in these patients.

RESULTS

Acute cholangitis in older patients manifested as atypical symptoms characterized as infrequent Charcot's triad (4.2%) and comorbidity in one-third of the patients. Patients were graded as mild, moderate, and severe cholangitis in 104 (31.4%), 175 (52.9%), and 52 (15.7%), respectively. Urgent biliary drainage (≤24 hours) was performed for 80.5% (247/307) of patients. Very elderly patients tended to have more severe grades and were treated with sequential procedures of transient biliary drainage and stone removal at different sessions. Hospital stay was related to methods and timing of biliary drainage. Mortality was very low (1.5%) and not related to patient age but rather to the success or failure of biliary drainage and severity grading of the acute cholangitis.

CONCLUSIONS

The methods and timing used for biliary drainage and severity of cholangitis are the major determinants of mortality and hospital stay in elderly and very elderly patients with acute cholangitis. Urgent successful ERCP is mandatory for favorable prognosis in these patients.
