Background/AimsLiterature on the safety of endoscopic retrograde cholangiopancreatography (ERCP) in elderly patients is divided. Based on this we decided to examine the safety of ERCP in nonagenarian patients.MethodsA total of 1,389 patients, with a mean age of 63.94±19.62 years, underwent ERCP during the study period. There were 74 patients aged 90 years or older with a mean age of 92.07±1.8. Logistic regression showed that nonagenarian patients had a significantly increased odds of in-patient mortality (adjusted odds ratio [AOR]=9.6; 95% confidence interval [CI]=4, 23; p≤0.001). Charlson Comorbidity Index (CCI) ≥2 was also an independent predictor of in-patient mortality (AOR=2.4; 95% CI=1.2, 5.2; p=0.021). Age ≥90 was not associated with increased adverse events; however emergency procedures (AOR=2.4; 95% CI=1.5, 4; p<0.001) and CCI ≥2 (AOR=2.6; 95% CI=1.7, 4.0; p<0.001) were more likely to have adverse events. ConclusionsAge ≥90 and CCI ≥2 are independently associated with increased odds of in-patient mortality in patients undergoing ERCP, whereas emergency procedures and CCI ≥2 are associated with an increased adverse event rate. Caution must be exercised when considering ERCP in patients aged ≥90 years and those with a CCI ≥2.

A strong association between C. difficile infection and alkaline stool pH was found.

Increased BMI is not predictive of suboptimal bowel preparation for colonoscopy. The results of our study are pivotal given the increased risk of colorectal cancer in obese patients and their known lower rate of colorectal cancer screening in certain populations. It is important to avoid subjecting these patients to an intensive bowel preparation that may further discourage screening in a patient population that requires it.

Background/AimsPercutaneous endoscopic gastrostomy (PEG) is a relatively safe procedure; however, no study has evaluated the safety of PEG tube placement in patients over the age of 100 years. MethodsWe conducted a retrospective review of patient records for patients who underwent PEG tube placement. Thirty patients aged 100 years and older were identified and a random sample of 275 patients was selected for comparison. ResultsThe mean age of the patients was 80.6±16.2 years. No procedure-related deaths or major complications were identified; the overall inpatient mortality rate was 7.6%. Minor complications were noted in 4% (n=12) of the patients. Centenarian patients were predominantly female (80% [n=24] vs. 54% [n=147], p=0.006), with a mean age of 100.5±0.9 years. There was no significant difference in procedural success rates (93.3% vs. 97.4%, p=0.222) or inpatient mortality (6.7% [n=2] vs. 7.7% [n=21], p=1.000) between the two groups. However, a higher minor complication rate was noted in the older patients (13.3% [n=4] vs. 2.9% [n=8], p=0.022). ConclusionsSuccess rates, major complications and inpatient mortality associated with PEG tubes in patients aged over 100 years are comparable to those observed in relatively younger patients at our center; however minor complication rates are relatively higher. These findings lead us to believe that PEG tubes may be safely attempted in carefully selected patients in this subset of the population.
