Insights
Percutaneous cholecystostomy (PC) for acute cholecystitis (AC) has high mortality when performed alone. Subsequent cholecystectomy (CCY) significantly reduces mortality, suggesting CCY should be prioritized over PC alone.
Area of Science:
- Medical research
- Surgical outcomes
- Gastroenterology
Background:
- Percutaneous cholecystostomy (PC) is an alternative for acute cholecystitis (AC) when cholecystectomy (CCY) is not feasible.
- The efficacy and role of PC as a definitive treatment for AC remain debated.
Purpose of the Study:
- To retrospectively analyze the outcomes of patients treated with PC for AC.
- To evaluate the impact of subsequent cholecystectomy (CCY) on mortality rates after PC.
Main Methods:
- Retrospective analysis of 158 patients undergoing PC for AC over 10 years.
- Comparison of mortality rates between PC alone and PC followed by CCY.
- Multivariable logistic regression and landmark sensitivity analysis to control for confounders and bias.
Main Results:
- Mortality was significantly higher in patients treated with PC alone (48%) compared to those who underwent subsequent CCY (9%).
- Subsequent CCY was associated with an 85% lower risk of mortality.
- Direct PC complications occurred in 17% of patients, with most AC specimens showing persistent inflammation.
Conclusions:
- PC alone is associated with high mortality and is not a definitive treatment for AC.
- Performing upfront cholecystectomy (CCY) is recommended due to the high mortality associated with PC alone.
- PC should be considered a short-term measure due to persistent inflammation in AC specimens.
Background:
Percutaneous cholecystostomy (PC) is a treatment option for acute cholecystitis (AC) in cases where cholecystectomy (CCY) is not feasible due to limited health conditions. The use of PC remains questionable. The aim was to retrospectively analyse the outcome of patients after PC.
Methods:
All patients who underwent PC for AC at a tertiary referral hospital over 10 years were included. Descriptive statistics, analysed mortality with and without CCY after PC, and a multivariable logistic regression for potential confounder and a landmark sensitivity analysis for immortal time bias were used.
Results:
Of 158 patients, 79 were treated with PC alone and 79 had PC with subsequent CCY. Without CCY, 48% (38 patients) died compared to 9% with CCY. In the multivariable analysis CCY was associated with 85% lower risk of mortality. The landmark analysis was compatible with the main analyses. Direct PC-complications occurred in 17% patients. Histologically, 22/75 (29%) specimens showed chronic cholecystitis, and 76% AC.
Conclusion:
Due to the high mortality rate of PC alone, performing up-front CCY is proposed. PC represents no definitive treatment for AC and should remain a short-term solution because of the persistent inflammatory focus. According to these findings, almost all specimens showed persistent inflammation.
