Abstract
BACKGROUND: Abdominoplasty using progressive tension sutures (PTS) without drains has been reported to lower seroma risk. However, evidence regarding the reproducibility of PTS drainless abdominoplasty in lowering seroma risk is inconsistent and limited to a few studies. OBJECTIVES: The purpose of this review and meta-analysis was to assess the efficacy of PTS without drains in reducing seroma rates associated with abdominoplasty. METHODS: PubMed, EMBASE, and Cochrane databases were searched with no restrictions for randomized controlled trials (RCTs) and observational studies in which the number of patients who experienced postoperative seroma was indicated. The keywords included ''progressive tension sutures,'' ''quilting sutures,'' "drain," and "abdominoplasty.'' Review Manager software (RevMan, version 5.3) was utilized to compute the pooled effect estimate using a random-effects Mantel-Haenszel model. The outcomes were expressed as odds ratios (OR) and 95% confidence intervals (CI). Subgroup analysis was conducted based on whether abdominoplasty was combined with liposuction. RESULTS: Five studies were included (one RCT and four retrospective studies) involving a total of 1255 adult patients. Patients who underwent abdominoplasty using PTS without drains experienced a significantly lower rate of postoperative seroma compared to those with drains (D) only (OR, 0.36; 95% CI, 0.19-0.70; P = 0.002; I2 = 9%). There was no significant difference in postoperative seroma rates between the PTS and PTS + D groups (OR, 1.03; 95% CI, 0.30-3.54; P = 0.96; I2 = 0%). The data analysis for the subgroup that included liposuction showed that compared with the use of drain only, PTS were associated with a significantly reduced number of seromas (OR, 0.24; 95% CI, 0.11-0.49; P = 0.0001; I2 = 0%). CONCLUSION: Abdominoplasty using PTS without drain and combined with liposuction was effective in reducing seroma rates. Additional RCTs with larger sample sizes and better comparability are needed to confirm the safety and effectiveness of the drainless abdominoplasty technique using progressive tension sutures. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.
