A retrospective analysis of clinical characteristics and mortality risks in elderly patients with acute cholecystitis and cholangitis / 中华内科杂志

ABSTRACT

Objective To analyze the clinical characteristics and explore the risk predictors on mortality in elderly patients with acute cholecystitis and cholangitis.Methods We conducted a retrospective analysis of elderly patients hospitalized in the Second Medical Center of General Liberation Army Hospital for acute cholecystitis and cholangitis during 2000 to 2018.Clinical data and risk predictors on mortality were assessed.The patients were stratified into three groups based on ageⅠ (65-74 years old),Ⅱ (75-84 years old),and Ⅲ (≥85 years old).Logistic regression analysis was used to identify the predictors of mortality.Results A total of 574 patients were finally enrolled with the mean age 87.6 years including 191 in group Ⅰ,167 in group Ⅱ,and 216 in group Ⅲ.The main cause of acute cholecystitis and cholangitis was gallstone (76.3％),and the main symptom was abdominal pain (62.9％),followed by chills(62.5％),fever(59.8％),jaundice (47.2％) and septic shock(26.3％).Cholecystitis was the most common diagnosis in groups Ⅰ and Ⅱ,whereas it was cholangitis in group Ⅲ.Percutaneous transhepatic biliary/gallbladder drainage (PTBD/PTGD) and endoscopic retrograde cholangiopancreatography (ERCP) were administrated more frequently in groups Ⅲ.A total of 35 patients (6.1％) died during follow-up.Senior in age (OR=11.1),the Charlson comorbidity index (OR=19.5),cancers (OR=9.6),blood stream infections (OR=7.4),severity of cholecystitis and cholangitis (OR=4.2)were risk factors associated with mortality.Conclusions Even in the elderly patients with acute cholecystitis and cholangitis,comorbidity is one of the main factors affecting clinical outcomes.Due to the poor performance,this group of population presents more severe disease and undergoes conservative treatment strategies.
