ThP6.1 - Revisiting outcomes of laparoscopic cholecystectomy in an elderly population

Abstract Aims Laparoscopic cholecystectomy in the elderly patient is a challenging operation with variable outcomes. We evaluate the outcome of patients who underwent laparoscopic cholecystectomy in a hospital that serves a large ageing population. Methods Retrospective analysis of 53 patients over the age of 70 years who underwent cholecystectomy between January and December 2023. Outcomes were compared between elective vs emergency procedures, indications, age groups (70-74, 75-79, 80-84, 85+) and Charlson comorbidity index (CCI). Results The mean age was 77±4.9 years, and the mean CCI was 4±1. Of 53 procedures performed, 30.2% (n=16) were emergency and 69.8% (n=37) were elective. 6.3% (n=1) was converted to open. 11.3% (n=6) of patients underwent Rendezvous ERCP. Emergency patients had increased length of stay (LOS) (5.1±2.8 vs 1.6±4.1, p=0.04). The indication for surgery was noted to have a significant influence on LOS (p=0.003), however, age groups and CCI did not influence LOS. Non-biliary complications occurred in 13.2% (n=7) of patients. 7.5% (n=4) of patients had readmission within 30 days. 3.75% (n=2) had retained CBD stone and underwent postoperative ERCP. No significant differences between age groups in relation to complications were identified. Conclusions Emergency cholecystectomy in patients over the age of 70 is associated with a longer LOS. Rates of complications are not influenced by age or CCI. Laparoscopic Cholecystectomy can be safely offered to a diverse elderly population.
