Table 5 Operation time and postoperative hospital stay for non-randomised patients according to multiple regression analysis

From: Non-randomised patients in a cholecystectomy trial: characteristics, procedures, and outcomes

  Operation time* min Postoperative hospital stay** Days
MC – OC -2.7 p = 0.50 -1.3 p = 0.004
LC – OC 20.2 p < 0.001 -1.2 p = 0.003
  1. MC = minilaparotomy cholecystectomy, LC = laparoscopic cholecystectomy, and OC = conventional open cholecystectomy. Figures indicate adjusted differences between MC or LC and OC.
  2. *Operation time adjusted for common bile duct exploration and concomitant operation.
  3. **Postoperative hospital stay adjusted for pancreatitis, malignant disease, common bile duct exploration, biliodigestive shunt operation, co-morbidity, ASA-score, concomitant operation, and acute operation.
