title: Factors influencing laparoscopic colorectal operative duration and its effect on clinical outcome.
abstract: BACKGROUND
  This study aimed to identify factors affecting laparoscopic colorectal operative duration and determine the impact of prolonged operative time.
  
  
  METHODS
  Data were collected prospectively on all laparoscopic colorectal operations performed within 1 institution over a period of 4 years. Patients' demographics, CR-POSSUM scores, intraoperative details, surgeon experience, and postoperative outcomes were recorded and assessed in relation to operative duration.
  
  
  RESULTS
  Two hundred laparoscopic colorectal operations were performed (137 cancers, 63 benign). Operation duration correlated to operation type (P<0.001) and CR-POSSUM mortality risk (P = 0.03). Operative duration positively correlated with incidence of postoperative complications (P = 0.02) and length of stay (P = 0.05). Operation time >180 minutes was associated with increased incidence of postoperative complications (P = 0.006).
  
  
  CONCLUSIONS
  The type of laparoscopic colorectal surgical operation performed has a significantly greater impact upon operative duration than individual patient parameters, pathology, or surgical experience. Operative time is associated with a greater risk of complications and longer hospital stay.
