Factors Influencing Failure to Undergo Interval Cholecystectomy After Percutaneous Cholecystostomy Among Patients With Acute Cholecystitis: a Retrospective Study
Abstract Background: Percutaneous cholecystostomy (PC) with interval cholecystectomy is an effective treatment modality in high-risk patients with acute cholecystitis. However, some patients still fail to undergo interval cholecystectomy after PC, with the reasons rarely reported. Hence, this study aimed to explore the factors that prevent a patient from undergoing interval cholecystectomy.Methods: Data from patients with acute cholecystitis who had undergone PC from January 1, 2017, to December 31, 2019, in our hospital were retrospectively collected. The follow-up endpoint was the patient undergoing cholecystectomy. Patients who failed to undergo cholecystectomy were followed up every three months until death. Univariate and multivariate analyses were performed to analyze the factors influencing failure to undergo interval cholecystectomy. A nomogram was used to predict the numerical probability of non-interval cholecystectomy.Results: In total, 205 participants were identified, and 67 (32.7%) patients did not undergo cholecystectomy during the follow-up period. Multivariate analysis revealed that Tokyo guidelines 2018 (TG18) grade III status (odds ratio [OR]: 3.83; 95% confidence interval [CI]: 1.27–11.49; p=0.017), acalculous cholecystitis (OR: 4.55; 95% CI: 1.59–12.50; p=0.005), albumin level <28 g/L (OR: 4.15; 95% CI: 1.09–15.81; p=0.037), and history of malignancy (OR: 4.65; 95% CI: 1.62–13.37; p=0.004) were independent risk factors for a patient’s failure to undergo interval cholecystectomy. Among them, history of malignancy showed the highest predictor point on the nomogram for predicting non-interval cholecystectomy.Conclusions: TG18 grade III status, acalculous cholecystitis, severe hypoproteinemia, and history of malignancy are the factors influencing failure to undergo cholecystectomy after PC in patients with acute cholecystitis.
