TL;DR
This study reviews the effectiveness and safety of ultrasound-guided cholecystostomy in high-risk patients with acute cholecystitis.
Contribution
The paper provides a meta-analysis of ultrasound-guided percutaneous cholecystostomy outcomes with specific focus on technical and clinical success rates.
Findings
Ultrasound-guided cholecystostomy has a pooled technical success rate of 99.3%.
Clinical success is reported at 97.6%, though definitions vary across studies.
Major adverse events occur in 1.7% of cases with no significant heterogeneity.
Abstract
Ultrasound-guided percutaneous cholecystostomy (US-PC) is widely used in high-risk surgical patients with acute cholecystitis. Still, success and safety rates specific to US guidance are not always distinguished within mixed 'image-guided' series. To estimate technical success, clinical success, and major complication rates of US-PC. Methods. Primary studies explicitly reporting US-PC or with separable data were included. Primary outcomes: technical success, clinical success (as defined by the study), and major adverse events (AEs). Single-arm meta-analysis using random-effects (logit, continuity correction); heterogeneity by I2 and prediction interval. Results. Four eligible single-arm studies for technical success (N = 466). Pooled technical success 99.3% (95%CI 97.8–99.8; I2 = 0%). Three studies (N = 223) reported clinical success: pooled 97.6% (95%CI 83.4–99.7; I2≈64% due to…
