Overview

Retrospective analysis reveals that routine abdominal drain placement does not significantly affect surgical site infection rates in adults, suggesting current guidelines may be adequate.

Key Points

  • The abdominal drain group had an overall surgical site infection rate of 24%, showing no significant difference after propensity score matching.
  • Operative time was significantly longer in the abdominal drain group, averaging significantly more than in the non-drain group (P = 0.010).
  • Patients with abdominal drains required more postoperative antibiotic use and had longer hospital stays, both significant at P < 0.001.
  • Propensity score matching helped balance clinical characteristics, ensuring the reliability of results with no significant differences (P > 0.05).
