Safety and outcomes of laparoscopic cholecystectomy in the extremely elderly: a systematic review and meta-analysis.

ABSTRACT

Background: Gallstones are a common cause of morbidity in the elderly. Operative treatment is often avoided due to concerns about poor outcomes but the evidence for this is unclear. We aim to consolidate available evidence assessing laparoscopic cholecystectomy outcomes in the extreme elderly (>80s) compared to younger patients. Methods: Studies comparing laparoscopic cholecystectomy in >80s with younger patients were considered. Total complications, mortality, conversion, bile duct injury, and length of stay were compared between the two groups. Results: Twelve studies including 366,522 patients were included. They were of moderate overall quality. The elderly group had more complicated gallbladder disease and also had more co-morbidities and a higher ASA grade. The risk of morbidity was lower in the younger group (RR 0.58 (95% CI 0.58-0.59)) with a slightly lower risk of conversion (RR 0.96 (0.94-0.98)) Length of stay was significantly longer for the elderly patients. Differences in mortality and bile duct injury were non-significant in all but one study. Conclusion: Laparoscopic cholecystectomy is safe and effective in the extreme elderly. Higher complication rates are predominantly related to increased co-morbidities and more complex gallbladder disease. Patients should be carefully selected, and cholecystectomy performed at an earlier stage to minimize these problems.
