Meta-analysis on the comparative efficacy of drains, progressive tension sutures and subscarpal fat preservation in reducing complications of abdominoplasty

Clinical Evaluation of 310 Abdominoplasties and Measurement of Scar Level

BACKGROUND

Most published studies on abdominoplasty focus on methods to reduce the risk of seromas. These methods include limited dissection (lipoabdominoplasty), quilting sutures, and preservation of the Scarpa fascia. Quantitative evaluation of the aesthetic result has been lacking.

METHODS

A retrospective study was undertaken of all patients undergoing abdominoplasty in the author's practice from 2016 to 2022. A full abdominoplasty was performed, usually with liposuction (87%). All patients were treated under total intravenous anesthesia without paralysis or prone positioning. A single closed suction drain was removed 3 or 4 days after surgery. All procedures were performed as outpatients. Ultrasound surveillance was used to detect any deep venous thromboses. No patient received chemoprophylaxis. The operating table was flexed, often to 90°. Deep fascial anchoring sutures were used to attach the Scarpa fascia of the flap to the deep muscle fascia. Measurements of the scar level were made at intervals after surgery up to 1 year.

RESULTS

Three hundred ten patients were evaluated, including 300 women. The mean follow-up time was 1 year. The overall complication rate, which included minor scar deformities, was 35.8%. Five deep venous thromboses were detected. There were no hematomas. Fifteen patients (4.8%) developed seromas that were successfully treated by aspiration. The mean vertical scar level 1 month after surgery was 9.9 cm (range, 6.1-12.9 cm). There was no significant change in scar level at subsequent follow-up times up to 1 year. By comparison, the scar level in published studies ranged from 8.6 to 14.1 cm.

DISCUSSION

Avoidance of electrodissection reduces tissue trauma that causes seromas. Flexed patient positioning during surgery and deep fascial anchoring sutures are effective in keeping the scar low. By avoiding chemoprophylaxis, hematomas can be avoided. Limiting the dissection (lipoabdominoplasty), preserving the Scarpa fascia, and adding quilting (progressive tension) sutures are unnecessary.

CONCLUSIONS

Total intravenous anesthesia offers important safety advantages. Avoiding electrodissection is effective in keeping seroma rates at a tolerable level (5%), and the scar low and more easily concealed. Alternative methods present disadvantages that may contribute to a suboptimal aesthetic result and require additional operating time.

Scarpa Fascia Preservation to Reduce Seroma Rate on Massive Weight Loss Patients Undergoing Abdominoplasty: A Comparative Study

(1) Background: An increasing number of patients undergo bariatric surgery and seek body contouring surgery after massive weight loss (MWL). Abdominoplasty itself is associated with a high complication rate in these patients, particularly due to seroma formation. Scarpa fascia preservation (SFP) has been proven to be an efficient method of reducing seroma rates. We aimed to evaluate the possible benefits of SFP on massive weight loss patients comparatively. (2) Methods: This is a single-center retrospective comparative study encompassing 202 MWL patients operated between 2009 and 2019 at Turku University Hospital. Patients included in the study had a preoperative weight loss greater than 30 kg. Of them, 149 went through traditional abdominoplasty and 53 abdominoplasties with SFP. The primary outcome measure was seroma occurrence, while secondary outcomes included drainage amount, hospital stay, surgical site occurrence, and need for blood transfusion. (3) Results: The only statistically significant difference between groups on patients' demographics was the sex ratio, favoring females in the control group (43:10, 81% vs. 130:19, 87%, p = 0.018). SFP significantly reduced seroma occurrence (9.4% vs. 26.2%, p = 0.011) and decreased mean drainage duration (3.7 ± 2.4 vs. 5.3 ± 3.2 days, p = 0.025). There was a trend towards lower drainage output (214.1 ± 162.2 mL vs. 341.9 ± 480.5 mL, p = 0.060) and fewer postoperative days on ward in the SFP group. Other complication incidences did not differ between the groups. The multivariable analysis did not show any significant factor for seroma formation or surgical site occurrence. (4) Conclusions: Preserving Scarpa fascia on MWL patients may result in decreased seroma occurrence and a shorter time to drain removal.

Retrospective Analysis of Predictive Factors for Complications in Abdominoplasty in Massive Weight Loss Patients

INTRODUCTION

Ex-obese patients present with redundancy of abdominal skin and soft tissue due to massive weight loss (MWL). The plastic surgeon can restore the body shape through body contouring procedures. Hence the need to adequately direct patients to body contouring by identifying suitable candidates exists. Our work aims to retrospectively analyze the abdominoplasty complications in our case series to identify associated risk factors and evaluate the effect of combined procedures on abdominoplasty outcomes.

MATERIALS AND METHODS

We retrospectively investigated predictive factors of abdominoplasty procedure complications on 213 MWL patients who received abdominoplasty with and without rectus sheath plication, abdominal liposuction, and other body contouring procedures. We identified risk and protective factors with univariate and multivariate regression analysis. Furthermore, we assessed the impact of additional procedures on the complication rates.

RESULTS

The overall complication rate was 49.8% (26.8% minor complications; 23% major complications). The delayed wound healing rate was 27.7%, and the revision surgery rate was 25.8% (14.7% early revision; 14.2% late revision). These results were compared with literature reports. Several negative predictors emerged as non-modifiable (advanced age, diabetes mellitus, surgical mode of weight loss) or modifiable (preoperative obesity and body mass index (BMI); active smoking; preoperative anemia; use of fibrin glue or quilting sutures). Performing rectus sheath plication improved most of the outcomes. Liposuction of hypochondriac regions and flanks led to increased safety and reduced the risk of surgical dehiscence and delayed wound healing, in contrast to epimesogastric liposuction. The other combined body contouring procedures did not worsen the outcomes, except for poor scarring.

CONCLUSION

Our findings encourage us to continue associating rectus sheath plication, liposuction, and other body contouring surgeries with abdominoplasty. We emphasize the importance of proper patient selection, particularly with regard to anemia, before body contouring surgery in the interests of offering safe surgery and satisfactory results. Further studies are needed to investigate how the optimal BMI cut-off and abstinence from smoking (in terms of time) before surgery reduce postoperative complications.

Development and Initial Validation of a Novel Professional Aesthetic Scale for the Female Abdomen

BACKGROUND

A growing body of literature aims to describe abdominal aesthetic goals in order to tailor surgical and non-surgical treatment options to meet patient goals. We aimed to integrate lay-person perceptions into the design of a novel professional aesthetic scale for the abdomen.

METHODS

An iterative process of expert consensus was used to choose 5 domains -1) abdominal muscle lines, 2) abdominal shape, 3) scar, 4) skin, and 5) umbilicus. A survey was developed to measure global and domain-specific aesthetic preferences on 5 abdomens. This was distributed through Amazon Mechanical Turk to 340 respondents. Principal component analysis was used to integrate survey data into weights for each of the scale's sub-questions. Attending plastic surgeons then rated abdomens using the final scale, and reliability and validity were calculated.

RESULTS

The final scale included eleven sub-questions - hourglass shape, bulges, hernia, infraumbilical skin, supraumbilical skin, umbilicus shape, umbilicus medialization position, umbilicus height position, semilunar lines, central midline depression, scar - within the 5 domains. Central midline depression held the highest weight (16.1%) when correlated to global aesthetic rating, followed by semilunar lines (15.8%) and infraumbilical skin (11.8%). The final scale demonstrated strong validity (Pearson r=0.99) and was rated as easy to use by 7 attending plastic surgeons.

CONCLUSION

The final scale is the first published professional aesthetic scale for the abdomen that aims to integrate lay-person opinion. In addition, this analysis and survey data provide insights into the importance of eleven components in overall aesthetic appeal of the abdomen.

Post-bariatric Abdominoplasty: Identification of Risk Factors for Complications

PURPOSE

The aim was to evaluate the complication rate after abdominoplasty procedures performed in a high volume post-bariatric center and to identify predictors of complications.

MATERIAL AND METHODS

A retrospective analysis was performed and included all abdominoplasty procedures performed between January 2011 and December 2019. Complications classified according to the Clavien-Dindo classification were documented and potential risk factors were statistically evaluated.

RESULTS

A total of 898 patients were included. Overall complication rate was 29.8%. Type I complications (minor wound problems) occurred in 15.8% (n = 140). Type II complications requiring medical intervention occurred in 10% (n = 90). Five patients had deep venous thrombosis or pulmonary embolism; others received antibiotic treatment for wound infections. In total 42 type III complications occurred in 36 patients, with re-intervention for wound problems (n = 16), seroma (n = 16), umbilical necrosis (n = 4), and bleeding (n = 6). The weight of tissue resected (p < 0.001), the interval between bariatric and body contouring surgery (p < 0.05), preoperative BMI (p < 0.05), male gender (p < 0.05), diabetes mellitus type 2 (p = 0.05), and smoking (p < 0.05) were important predictors for developing complications.

CONCLUSION

In this large retrospective post-bariatric abdominoplasty series, the overall complication rate is low compared to other published series as a consequence of our completely standardized approach and technique. Our analysis shows a significant linear correlation between the amount of skin tissue resected and postoperative complications. Moreover, the longer the interval between bariatric surgery and abdominoplasty, the higher the complication rate. High preoperative BMI, diabetes mellitus type 2, smoking, and male gender were identified as independent significant risk factors for complications.

Efficacy of Progressive Tension Sutures without Drains in Reducing Seroma Rates of Abdominoplasty: A Systematic Review and Meta-Analysis

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.
