Cholecystostomy as Bridge to Surgery and as Definitive Treatment or Acute Cholecystectomy in Patients with Acute Cholecystitis

Figure 1

Cumulative recurrence rate after the first admission for patients treated with cholecystostomy and patients treated conservatively without intervention. The Kaplan-Meier plot was constructed by defining readmission for recurrent cholecystitis as terminal event and end of follow-up (December 31, 2011), death, or planned cholecystectomy as censored events. The difference between the groups was not statistically significant in univariate () or multivariate () Cox proportional hazard analysis with adjustment for age, gender, Charlson comorbidity index, and degree of cholecystitis.
