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.
