Clinical characteristics and short-term outcomes in patients with acute cholecystitis over aged >80 years.

ABSTRACT

AIM: We investigated the clinical characteristics and short-term outcomes in acute cholecystitis (AC) patients aged ≥80 years. We therefore sought to determine the ideal treatment for elderly patients with AC. METHODS: We retrospectively evaluated 253 patients with AC. The patients were divided into two groups according to their age elderly group (n = 77, aged ≥80 years) and non-elderly group (n = 176, aged <80 years). We compared the clinical characteristics, in-hospital mortality and recurrence of cholecystitis within 6 months between the two groups. The predictive factors for in-hospital mortality were also assessed. RESULTS: The elderly group had more severe comorbidities (P = 0.0055), higher severity grade of AC (P = 0.00071) and higher in-hospital mortality (P = 0.029) than the non-elderly group. The multivariate analysis showed that the serum creatinine level (hazard ratio 12.43; P = 0.002) was independently associated with the in-hospital mortality. The elderly group (20.8%) underwent subsequent cholecystectomy less frequently than the non-elderly group (63.2%; P < 0.0001). The recurrence rate of AC was comparable between the two groups (P = 0.89). The proportion of patients in the elderly group who received percutaneous drainage in the latter period (64.3%) was significantly higher than in the former period (33.3%; P = 0.015). CONCLUSIONS: More attention should be paid to AC patients with chronic renal disease after treatment. Percutaneous drainage might serve as a definitive treatment without subsequent cholecystectomy in elderly AC patients with various comorbidities. Geriatr Gerontol Int 2019; 19 208-212.
