Criteria for drain removal following liver resection

Area of Science:

• Hepatobiliary Surgery
• Surgical Oncology
• Gastroenterology

Background:

• Prophylactic abdominal drains are commonly used after liver resection but lack evidence-based removal guidelines.
• Optimal drain management is crucial for patient outcomes and resource utilization.

Purpose of the Study:

• To establish the optimal timing for the removal of prophylactic abdominal drains following liver resection.
• To identify reliable criteria for drain removal to minimize complications.

Main Methods:

• Analysis of prophylactic abdominal drain data in 316 liver resection patients (2006-2009).
• Measurement of drain-fluid bilirubin levels and bacteriological cultures on postoperative days 1, 3, 5, and 7.
• Drains removed on postoperative day 3 if bilirubin < 5 mg/dL and cultures were negative; otherwise, they remained in situ.

Main Results:

• Of 514 drains, 18.4% had positive cultures and 4.4% showed bile leakage (bilirubin ≥ 5 mg/dL).
• Postoperative day 3 drain-fluid bilirubin level was the strongest predictor of infection (OR 15.11, P < 0.001).
• A drain-fluid bilirubin level of 3.01 mg/dL on day 3 demonstrated high predictive value (83.6% accuracy, 3.9% false-positive rate).

Conclusions:

• The '3 × 3 rule' (drain-fluid bilirubin < 3 mg/dL on postoperative day 3) is an accurate criterion for prophylactic drain removal.
• This rule aids in safe and timely drain management after liver resection.
• Implementing this criterion can optimize patient care and reduce unnecessary drain-related complications.
