1. Quilt technique after mastectomy: stepped-wedge randomized cluster trial showing superior textbook outcome and reduced healthcare utilization.
In a 12-center stepped-wedge randomized cluster trial (n=251), quilting after mastectomy significantly improved textbook outcome (65.7% vs 41.3%) and reduced wound complications including clinically significant seroma (24.0% vs 55.6%) and unscheduled visits, without worsening pain, shoulder function, satisfaction, or cosmetic results.
Impact: This pragmatic randomized implementation trial provides high-level evidence to standardize closure technique after mastectomy, reducing complications and resource use without cosmetic trade-offs.
Clinical Implications: Adopt quilting closure as a routine practice after mastectomy to reduce seroma and healthcare utilization while maintaining patient-reported pain, function, and cosmetic outcomes. Discuss with patients as part of enhanced recovery protocols.
Key Findings
- Textbook outcome improved with quilting: 65.7% vs 41.3% (P=0.003).
- Wound complications including significant seroma reduced: 24.0% vs 55.6% (P<0.001).
- Unscheduled outpatient visits decreased: 30.2% vs 44.4% (P=0.048).
- No significant differences in postoperative pain, shoulder function, satisfaction, chest well-being, or cosmetic outcome.
Methodological Strengths
- Stepped-wedge randomized cluster design across 12 hospitals enhances external validity.
- Prospectively defined composite primary endpoint and trial registration (NCT05272904).
Limitations
- Cluster design susceptible to secular trends and potential confounding by implementation timing.
- Moderate sample size and unblinded nature may influence subjective secondary outcomes.
Future Directions: Cost-effectiveness analyses and subgroup evaluations (e.g., immediate reconstruction, anticoagulation) could refine indications; standardized quilting protocols and training should be evaluated for scalability.
INTRODUCTION: The quilt technique to minimize post-mastectomy seroma has been adopted slowly due to concerns about potential long-term side effects, longer operating times, and cost-effectiveness. This study aimed to evaluate the implementation of the quilt technique on textbook outcome in patients undergoing mastectomy. METHODS: A stepped-wedge randomized cluster trial was conducted in 12 Dutch hospitals, each representing a cluster. Patients who underwent the quilt technique after mastectomy were compared with those with conventional closure. Primary outcome was textbook outcome, defined as the absence of wound complications, readmissions, reoperations, or unscheduled outpatient visits, and no increase in pain medication use 6 months after surgery compared to preoperative use. Secondary outcomes were related to healthcare consumption and patient satisfaction. RESULTS: Two hundred and fifty-one patients who underwent mastectomy were included. The incidence of textbook outcome was higher in the quilted cohort compared to the non-quilted cohort, 94 of 143 (65.7%) versus 26 of 63 patients (41.3%, P = 0.003). Wound complications, including clinically significant seroma, were 24.0% in the quilted patients versus 55.6% in the non-quilted patients (P < 0.001). In the quilted cohort, 30.2% of patients required an unscheduled outpatient clinic visit, compared to 44.4% in the non-quilted cohort (P = 0.048). No significant differences were observed in postoperative pain, shoulder function, satisfaction and physical well-being of the chest, or cosmetic outcome. CONCLUSION: Quilting after mastectomy was superior to conventional closure in terms of textbook outcome and healthcare consumption without any undesirable side effects.

2. Postoperative Cosmetic Outcomes and Quality of Life After Thyroidectomy: A Systematic Review and Network Meta-Analysis.
Across 57 studies including 9,206 patients, remote-access approaches and MIVAT yielded better cosmetic outcomes than conventional transcervical thyroidectomy; transoral (TOA) and bilateral axillo-breast (BABA) approaches ranked highest and generally showed better QOL metrics.
Impact: Provides a comprehensive comparative framework to counsel patients who prioritize cosmetic and psychosocial outcomes when selecting thyroidectomy approaches.
Clinical Implications: Offer remote-access (particularly TOA or BABA) or MIVAT to suitable candidates seeking superior cosmesis; counsel on surgeon expertise, learning curve, and potential trade-offs, while noting that QOL evidence is still developing.
Key Findings
- All remote-access techniques and MIVAT had superior cosmetic outcomes compared with conventional transcervical approach.
- Transoral (TOA) and BABA approaches ranked highest for cosmesis and generally for QOL.
- QOL data are positive but limited, warranting cautious interpretation.
Methodological Strengths
- Network meta-analysis enables indirect comparisons across multiple surgical approaches.
- Large aggregated sample (9,206 patients) with random-effects modeling.
Limitations
- Underlying studies vary in design and quality; potential heterogeneity and selection bias.
- QOL outcomes inconsistently reported; limited long-term data.
Future Directions: Prospective comparative trials with standardized QOL and cosmetic measures and long-term follow-up are needed; cost-effectiveness and training pathways should be systematically evaluated.
BACKGROUND: Remote-access thyroidectomy and minimally invasive video-assisted thyroidectomy (MIVAT) were developed to improve cosmesis over the conventional transcervical approach (CTA). However, comparative data on cosmetic and quality of life (QOL) outcomes remain limited. METHODS: A systematic review and random-effects network meta-analysis was performed to compare MIVAT, five remote-access approaches-breast approach (BA), bilateral axillo-breast approach (BABA), gasless transaxillary approach (GTAA), retroauricular approach (RA), and transoral approach (TOA)-with CTA. RESULTS: Fifty-seven studies (9206 patients) were included. All remote-access techniques and MIVAT showed superior cosmetic outcomes versus CTA. TOA and BABA ranked highest. Remote-access approaches, particularly TOA, BABA, and GTAA, demonstrated generally better QOL outcomes than CTA and MIVAT. CONCLUSIONS: Remote-access approaches and MIVAT offer superior cosmesis over CTA. TOA and BABA generally rank highest in both cosmesis and QOL, although evidence on QOL remains limited. These approaches may be considered for patients prioritizing aesthetic and psychosocial outcomes.
3. Postmastectomy radiation therapy for implant-based breast reconstruction: a systematic review and meta-analysis for the 2022 Japanese Breast Cancer Society Clinical Practice Guideline.
Across 23 studies, PMRT in immediate implant-based reconstruction substantially increased major complications, reconstruction failure, and capsular contracture and worsened cosmetic outcomes, informing risk counseling and reconstructive planning.
Impact: Quantifies key risks of PMRT in implant reconstructions with effect sizes that can be directly used in shared decision-making and guideline development.
Clinical Implications: Counsel candidates for PMRT with implants on elevated risks of complications and cosmetic deterioration; consider autologous reconstruction, delayed-immediate strategies, or radiotherapy planning modifications to mitigate risks.
Key Findings
- PMRT increased major complications (OR 2.62; 95% CI 1.82–3.77).
- Reconstruction failure was higher with PMRT (OR 2.53; 95% CI 2.00–3.20).
- Capsular contracture risk markedly increased (OR 9.63; 95% CI 5.77–16.06).
- Cosmetic outcomes were significantly poorer with PMRT (OR 3.55; 95% CI 1.80–6.98).
Methodological Strengths
- Comprehensive search with predefined outcomes; random-effects meta-analysis.
- Clear clinical endpoints including cosmetic outcomes relevant to patient counseling.
Limitations
- Predominantly retrospective observational data with potential confounding.
- Heterogeneity in reconstructive techniques, radiation protocols, and follow-up reporting.
Future Directions: Prospective registries integrating radiation dosimetry, reconstructive techniques, and patient-reported aesthetic outcomes are needed; trials testing mitigation strategies (e.g., autologous conversion, acellular dermal matrices) should be prioritized.
BACKGROUND: Implant-based breast reconstruction is the most commonly performed reconstructive technique following mastectomy. With an increasing number of patients undergoing implant-based breast reconstruction, concerns have arisen regarding the safety of postmastectomy radiation therapy (PMRT) in reconstructed breasts. This study aimed to investigate the safety of PMRT in implant-based breast reconstruction. METHODS: A comprehensive literature search was conducted for articles published up to March 2021. Eligible studies included clinical trials and observational studies comparing outcomes between patients with breast cancer undergoing immediate implant-based breast reconstruction with PMRT and those without PMRT. The primary outcomes included major complications, reconstruction failure, capsular contracture, and cosmetic outcomes. Pooled odds ratio (OR) with 95% confidence interval (CI) were calculated using a random-effects model. RESULTS: A total of 23 studies were identified, comprising one case-control study, one prospective cohort study, and 21 retrospective cohort studies. PMRT was significantly associated with increased rates of major complications (OR 2.62, 95% CI 1.82-3.77, P < 0.00001), reconstruction failure (OR 2.53, 95% CI 2.00-3.20, P < 0.00001), and capsular contracture (OR 9.63, 95% CI 5.77-16.06, P < 0.00001). Furthermore, cosmetic outcomes were significantly poorer in patients undergoing PMRT compared with those not receiving PMRT (OR 3.55, 95% CI 1.80-6.98, P < 0.003). CONCLUSIONS: This meta-analysis demonstrated that PMRT in implant-based breast reconstruction is associated with a significantly increased risk of adverse outcomes. Given these risks, treatment decisions should involve through discussions with patients to ensure that they are fully informed of the potential benefits and complications.
