Abstract
Background
Although cholecystectomy is a common surgery, it carries higher risks of postoperative complications and mortality for older adults. Age alone is not a reliable predictor of postoperative outcomes, whereas frailty may provide a more accurate assessment of a patient's health and functional status. Frailty, characterized by physical deterioration and reduced resilience, has been shown to predict mortality, prolonged recovery, and morbidity after various surgeries, including cholecystectomy. Thus, incorporating frailty evaluations into preoperative assessments can improve patient outcomes by individualizing treatment strategies. This systematic review and meta-analysis aims to evaluate how well frailty predicts postoperative outcomes following cholecystectomy.
Methods
In accordance with PRISMA guidelines, we searched PubMed, Embase, and Web of Science on August 14th, 2024, without restrictions on publication year or language. The quality of the studies was assessed using the Newcastle–Ottawa scale, and meta-analysis was conducted using odds ratios with 95% confidence intervals as the effect size, employing a random-effects model.
Results
Nine cohort studies comprising a total of 128,421 participants were included. The pooled results showed significantly higher odds of short-term mortality (OR: 5.54, 95% CI: 1.65–18.60, p = 0.006), postoperative morbidity (OR: 2.65, 95% CI: 1.51–4.64, p = 0.001), major morbidity (OR: 3.61, 95% CI: 1.52–8.59), and respiratory failure (OR: 3.85, 95% CI: 1.08–13.79) among frail patients. Additionally, frail patients had longer hospital stays (mean difference: 2.98 days, 95% CI: 1.91–4.04) and significantly higher odds of postoperative infection and sepsis. However, no association was evident with reoperation rates.
Conclusion
This study highlights the value of utilizing frailty assessment tools in preoperative settings for predicting outcomes after cholecystectomy. These tools could improve decision-making in both emergency and elective situations, aiding in the choice between surgical and medical management, as well as between open and laparoscopic procedures tailored to each patient.
