APACHE IV system helps to determine role of cholecystostomy in elderly patients with acute cholecystitis

OBJECTIVE: Cholecystostomy is a palliative treatment for patients unfit to undergo immediate cholecystectomy. Nevertheless, the role of cholecystostomy in the clinical management of such patients remains unclear. The Acute Physiology and Chronic Health Evaluation IV (APACHE IV) scoring system is useful for estimating the hospital mortality of high-risk patients. We evaluated the therapeutic effect of cholecystostomy by the APACHE IV scoring system in patients aged >65 years with acute cholecystitis. METHODS: In total, 597 patients aged >65 years with acute cholecystitis were retrospectively analyzed using APACHE IV scores. RESULTS: The fitness of the APACHE IV score prediction was good, with an area under the receiver operating characteristic curve of 0.894. The chi square independence test indicated that compared with conservative treatment, cholecystostomy may have different effects on mortality for patients whose estimated mortality rate was >10%. Comparison of the estimated mortality of patients before and after cholecystostomy indicated that the estimated mortality was significantly lower after than before puncture, both in the whole patient group and in the group with an estimated mortality of >10%. CONCLUSION: The APACHE IV scoring system showed that cholecystostomy is a safe and effective treatment for elderly high-risk patients with acute cholecystitis.
