title: High rate of common bile duct stones and postoperative abscess following percutaneous cholecystostomy.
abstract: BACKGROUND
  The short and long-term outcomes in patients managed with percutaneous cholecystostomy (PCY) at a single institution are described.
  
  
  METHODS
  A retrospective study was conducted for patients treated between February 2000 and November 2012. Patient charts, imaging and biochemical data were reviewed. Patient demographics, presenting clinical features and treatment variables were noted. Outcome variables were length of admission, 30-day mortality, 30-day unplanned readmission, tube dislodgement, abscess formation, subsequent endoscopic retrograde cholangiography and surgery, complications after surgery and median overall survival.
  
  
  RESULTS
  PCY was performed for 55 patients for acute cholecystitis where surgical risk was very high. The 30-day readmission rate was 20% (n=11), the 30-day mortality rate was 9% (n=5) and median survival was 59 months (95% confidence interval: 30-88 months). The median follow-up duration was 68 months. Tubes were dislodged in 15 patients (27%) and an abscess occurred after PCY in 5 patients (9%). Subsequent endoscopic common bile duct stone extraction was required in 20 patients (36%). Cholecystectomy was planned in 22 patients and an abscess occurred following the cholecystectomy in 5 (23%).
  
  
  CONCLUSIONS
  Although a PCY is lifesaving, significant morbidity can arise during recovery. This study demonstrates a high rate of choledocholithiasis (44%), tube dislodgement (27%) and postoperative abscess (23%) compared with previous reports.
