Surgical duration alone does not significantly increase postoperative complications like sepsis or hospital stay. Meticulous surgical techniques, while lengthening operating times, contribute to reduced complication rates and shorter recovery periods.

Area of Science:

  • Surgical Outcomes
  • Infectious Disease Epidemiology

Background:

  • The role of surgical duration in postoperative complications is debated.
  • Previous studies suggest a link between longer operative times and increased morbidity.

Purpose of the Study:

  • To investigate the independent impact of surgical duration on septic complications, anastomotic dehiscence, and postoperative hospital stay.
  • To analyze the relationship between antibiotic prophylaxis timing and sepsis incidence in relation to surgical duration.

Main Methods:

  • Retrospective analysis of 500 patients undergoing abdominal or colorectal surgery.
  • Patients divided into four homogeneous groups based on surgical site contamination.
  • Anesthesiological records used to determine mean operating times.

Main Results:

  • Surgical duration, when considered alone, did not significantly correlate with increased septic complications or anastomotic dehiscence.
  • Meticulous surgical practices, leading to longer operating times, were associated with reduced sepsis incidence (4%) and shorter mean postoperative hospital stay (13 days).
  • Antibiotic prophylaxis timing influenced sepsis rates: >1 hour pre-op (20% sepsis) vs. coinciding with anesthesia induction (13% sepsis).

Conclusions:

  • Prolonged surgical times, often due to careful complication prevention, do not independently increase postoperative complications.
  • Optimal timing of antibiotic prophylaxis is crucial for reducing sepsis incidence, irrespective of surgical duration.
