Abstract
Background
Acute cholecystectomy is standard treatment for acute cholecystitis. However, many patients are still treated conservatively and undergo delayed elective surgery. The aim of this study was to determine the ideal time to perform an elective cholecystectomy after acute cholecystitis.
Methods
All patients treated for acute cholecystitis in Sweden between 2006 and 2013 were identified through the Swedish Patient Register. This cohort was cross-linked with the Swedish Register for Gallstone Surgery, GallRiks, where information on surgical outcome was retrieved. The impact of the time interval after discharge from hospital to elective surgery was analysed by multivariate logistic regression adjusting for gender and age.
Results
After exclusion of patients not subjected to surgery, not registered in GallRiks and patients treated with acute cholecystectomy, 8532 remained. This cohort was divided into six-time categories. Using the first time interval < 11 days from discharge to elective surgery as the reference category the chance of completing surgery with a minimally invasive technique was increased for all categories (p < 0.05). The risk for perioperative complication and cystic duct leakage was reduced if surgery was undertaken > 30 days after discharge (both p < 0.05). The risk for bile duct injury was significantly increased if the procedure was undertaken > 365 days after discharge (p = 0.030). The chance of completing the procedure within 100 min was not affected by time.
Conclusion
For patients undergoing elective cholecystectomy after acute cholecystitis, the safety of the procedure increases if surgery is performed more than 30 days after discharge from the primary admission.
