Insights
The Charlson Comorbidity Index (CCI) can predict difficult cholecystectomy in patients with acute cholecystitis. Further research is needed to determine if CCI predicts adverse outcomes in these patients.
Area of Science:
- Surgical Outcomes Research
- Gastrointestinal Surgery
- Predictive Analytics in Medicine
Background:
- The Charlson Comorbidity Index (CCI) is a validated predictor of survival and post-surgical mortality.
- CCI is incorporated into the Tokyo Guidelines for managing acute cholecystitis.
- The predictive role of CCI for surgical difficulty in cholecystectomy requires further evaluation.
Purpose of the Study:
- To assess the efficacy of the Charlson Comorbidity Index (CCI) in predicting difficult cholecystectomies.
- To compare the predictive value of CCI with the Emergency Surgery Score (ESS) and ASA score for surgical difficulty.
Main Methods:
- A retrospective analysis of 96 patients who underwent cholecystectomy for acute cholecystitis from January 2017 to September 2019.
- Calculation and analysis of Charlson Comorbidity Index (CCI), Emergency Surgery Score (ESS), and American Society of Anesthesiologists (ASA) scores.
- Stratification of patients into difficult and non-difficult cholecystectomy groups to evaluate predictive accuracy.
Main Results:
- The Charlson Comorbidity Index (CCI) significantly predicted difficult cholecystectomy (OR 1.59, p=0.031).
- The Emergency Surgery Score (ESS) also demonstrated predictive value for difficult cholecystectomy (OR 1.42, p=0.024).
- No significant differences in adverse outcomes were observed between the difficult and non-difficult cholecystectomy groups.
Conclusions:
- The Charlson Comorbidity Index (CCI) is a potential predictor of surgical difficulty in patients undergoing cholecystectomy for acute cholecystitis.
- Further investigation is warranted to ascertain CCI's utility in predicting adverse outcomes within this patient population.
Abstract:
Background The Charlson Comorbidity Index (CCI) has been validated as a predictor of overall survival and post-surgical mortality. CCI is adopted by Tokyo Guidelines as one of the main criteria in the management of acute cholecystitis. Our study evaluates the role of CCI in predicting difficult cholecystectomy. Methods All patients who underwent cholecystectomy for acute cholecystitis between January 2017 and September 2019 were included. CCI, Emergency Surgery Score (ESS), and American Society of Anesthesiologists (ASA) score were calculated and analyzed to assess their predictive value for difficult cholecystectomy. Results A total of 96 patients were included and allocated to difficult and non-difficult cholecystectomy groups. CCI was found to be a significant predictor of difficult cholecystectomy (OR 1.59; 59% CI, 1.04. 2.42; p= 0.031). Similarly, ESS was found to be a predictor tool of difficult cholecystectomy (OR 1.42; 59% CI, 1.05. 1.93; p= 0.024). There was no significant difference in adverse outcomes between the two groups. Conclusion CCI was able to predict a difficult cholecystectomy in our study population. However further studies are required to evaluate if it can be used as a predictor of adverse outcomes in the context of acute cholecystitis.
