Objective
To compare outcomes following percutaneous cholecystostomy drain placement based on presence or absence of Tokyo Guidelines diagnostic criteria for acute cholecystitis.
Methods
Chart review was performed to identify the presence or absence of Tokyo Guidelines diagnostic criteria for acute cholecystitis in 146 patients who underwent percutaneous cholecystostomy between 2012 and 2015. Those who met criteria were compared to those who did not in terms of demographics, laboratory values, drain indwelling time, treatment response, eventual surgical management, and 30-day mortality.
Results
94 patients (64%) met Tokyo Guidelines diagnostic criteria, while 52 did not (36%). Patients within criteria had a shorter mean length of stay (13.5 days vs 18.9 days), were more likely to have a positive gallbladder fluid culture (64.5% vs 28.6%), demonstrated greater response to treatment (87.2% vs 32.7%), and had lower 30-day mortality (6.4% vs 37.8%). There was no significant difference in terms of ICU requirement (38.3% vs 38.9%), mean drain indwelling time (58.8 days vs 65.3 days), eventual laparoscopic cholecystectomy (40.4% vs 25.0%), or open cholecystectomy performed (9.5% vs 9.6%).
Conclusion
Patients outside of Tokyo Guidelines diagnostic criteria for acute cholecystitis were less likely to respond to treatment with percutaneous cholecystostomy and had worse outcomes. Further research may be indicated to better define the indications for percutaneous cholecystostomy placement in this group.
