Effect of drainage versus no drainage after thyroid surgery on wound complications, a meta-analysis

A meta-analysis study was used to assess whether not placing a drain after thyroidectomy reduces postoperative wound complications. A critical review of the comprehensive literature up to May 2023 was conducted using four databases: PubMed, Embase, the Cochrane Library, and the web of science. Fourteen interrelated studies were reviewed after passing the inclusion and exclusion criteria established by the study and assessing the quality of the literature.95% confidence intervals (Cl) and odds ratios (OR) were calculated using fixed effects models. The data were meta-analysed using RevMan 5.3 software. The results showed that the use of drains during thyroid surgery did not have a favourable impact on patients. Intraoperative placement of drains did not reduce postoperative wound haematoma formation in patients, (OR, 0.86; 95% CI, 0.54, 1.36 p = 0.52). However, the incidence of postoperative wound infection was significantly higher in patients with drains used in intraoperative thyroid surgery, (OR, 0.22; 95% CI, 0.10, 0.45 p < 0.0001). As the sample size of the randomised controlled study used for this meta-analysis was limited, it is important to approach the findings with caution when interpreting the results.Conducting additional high-quality research with larger sample sizes is crucial in order to further confirm these results and reduce the likelihood of duplication.
