Percutaneous cholecystostomy as a definitive treatment for acute acalculous cholecystitis: clinical outcomes and risk factors for recurrent cholecystitis.

Abstract

OBJECTIVE:

To investigate the outcomes of percutaneous cholecystostomy (PC) as a definitive treatment for acute acalculous cholecystitis (AAC) and to identify the risk factors for cholecystitis recurrence after catheter removal.

METHODS:

Between January 2008 and December 2017, 124 patients who had undergone PC as definitive treatment for moderate or severe AAC. The initial clinical success, complications, and recurrent cholecystitis after PC removal were retrospectively assessed. Twenty-one relevant variables were analyzed to identify risk factors for recurrent cholecystitis.

RESULTS:

Clinical effectiveness was achieved in 107 patients (86.3%) at 3 days and in all patients (100%) at 5 days after PC placement. Six Grade 2 adverse events occurred, including catheter dislodgement (n = 3) and clogging (n = 3), which required catheter exchange. The PC catheter was removed in 123 patients (99.2%), with a median indwelling duration of 18 days (range 5-116 days). During the follow-up period (median, 1624 days; range, 40-4945 days), five patients experienced recurrent cholecystitis (4.1%). The cumulative recurrence rates were 3.3%, 4.1%, and 4.1% at 6 months, 1 year, and 5 years, respectively. Multivariate analysis revealed that an age-adjusted Charlson comorbidity index (aCCI)≥7 positively correlated with recurrence (OR, 1.97; 95% confidence interval, 1.07-3.64; p = 0.029).

CONCLUSIONS:

Definitive PC is a safe and effective treatment option for patients with AAC. The PC catheters can be safely removed in most patients. An aCCI≥7 was a risk factor for cholecystitis recurrence after catheter removal.

ADVANCES IN KNOWLEDGE:

1. Percutaneous cholecystostomy (PC) is a safe and effective as a definitive treatment in patients with acute acalculous cholecystitis (AAC).2. PC can be safely removed after recover from AAC in the majority of patients (99.2%) with low rate of recurrence of cholecystitis (4.1%).3. Age-adjusted Charlson comorbidity index ≥7 was a risk factor for recurrence of cholecystitis after PC removal.
