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  Overall, 205 participants were identified, and 67 (32.7%) did not undergo cholecystectomy during the follow-up period. Multivariate analysis revealed that having a 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), an albumin level < 28 g/L (OR: 4.15; 95% CI: 1.09–15.81;  p  = 0.037), and a 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, the presence of a history of malignancy exhibited the highest influence in the nomogram for predicting non-interval cholecystectomy.    Conclusions  Having a TG18 grade III status, acalculous cholecystitis, severe hypoproteinemia, and a history of malignancy influence the failure to undergo cholecystectomy after PC in patients with acute cholecystitis.
