Drains in thyroid surgery do not reduce reoperation rates for bleeding or complications like hematoma and seroma. However, using drains increases postoperative pain and hospital length of stay (LOS), with a potential rise in wound infections.
Area of Science:
- Surgical Oncology
- General Surgery
- Evidence-Based Medicine
Background:
- The utility of surgical drains following thyroidectomy remains debated.
- Previous studies suggest drains do not impact reoperation rates for hemorrhage.
Purpose of the Study:
- To systematically review randomized controlled trials (RCTs) on drain use in thyroid surgery.
- To evaluate the impact of drains on postoperative complications, pain, and hospital length of stay (LOS).
Main Methods:
- Systematic search of PubMed and Embase databases for relevant RCTs.
- Included 20 RCTs with 2,204 patients comparing thyroidectomy with or without drains.
- Analyzed reoperation rates, hematoma, seroma, wound infection, pain (VAS), and LOS.
Main Results:
- No significant difference in reoperation rates, hematoma, or seroma formation between drained and undrained groups.
- Drained patients reported significantly higher postoperative pain (MD 1.91) and prolonged hospital LOS (MD 1.34 days).
- A trend towards increased wound infection in drained patients was observed, though not consistently confirmed.
Conclusions:
- Surgical drains in thyroid surgery do not reduce reoperation rates or major complications.
- Drain use is associated with increased postoperative pain and extended hospital LOS.
- Further large-scale RCTs are needed to confirm the correlation with wound infection rates.
