Co-surgeon versus Single-surgeon Outcomes in Free Tissue Breast Reconstruction: A Meta-analysis.

BACKGROUND: Autologous breast reconstruction offers superior long-term patient reported outcomes compared with implant-based reconstruction. Universal adoption of free tissue transfer has been hindered by procedural complexity and long operative time with microsurgery. In many specialties, co-surgeon (CS) approaches are reported to decrease operative time while improving surgical outcomes. This systematic review and meta-analysis synthesizes the available literature to evaluate the potential benefit of a CS approach in autologous free tissue breast reconstruction versus single-surgeon (SS). METHODS: A systematic review and meta-analysis was conducted using PubMed, Embase, and MEDLINE from inception to December 2022. Published reports comparing CS to SS approaches in uni- and bilateral autologous breast reconstruction were identified. Primary outcomes included operative time, postoperative outcomes, processes of care, and financial impact. Risk of bias was assessed and outcomes were characterized with effect sizes. RESULTS: Eight retrospective studies reporting on 9,425 patients were included. Compared with SS, CS approach was associated with a significantly shorter operative time (SMD -0.65, 95% confidence interval [CI] -1.01 to -0.29, p < 0.001), with the largest effect size in bilateral reconstructions (standardized mean difference [SMD] -1.02, 95% CI -1.37 to -0.67, p < 0.00001). CS was also associated with a significant decrease in length of hospitalization (SMD -0.39, 95% CI -0.71 to -0.07, p = 0.02). Odds of flap failure or surgical complications including surgical site infection, hematoma, fat necrosis, and reexploration were not significantly different. CONCLUSION: CS free tissue breast reconstruction significantly shortens operative time and length of hospitalization compared with SS approaches without compromising postoperative outcomes. Further research should model processes and financial viability of its adoption in a variety of health care models.

Implementation of the Maryland Global Budget Revenue Model and Variation in the Expenditures and Outcomes of Surgical Care: A Systematic Review and Meta-analysis.

OBJECTIVE: To assess the effect of the Global Budget Revenue (GBR) program on outcomes after surgery. BACKGROUND: There is limited data summarizing the effect of the GBR program on surgical outcomes as compared with traditional fee-for-service systems. METHODS: The Medline, Embase, Scopus, and Web of Science databases were used to conduct a systematic literature search on April 5, 2022. We identified full-length reports of comparative studies involving patients who underwent surgery in Maryland after implementation of the GBR program. A random effects model calculated the overall pooled estimate for each outcome which included complications, rates of readmission and mortality, length of stay, and costs. RESULTS: Fourteen studies were included in the qualitative synthesis, with 8 unique studies included in the meta-analysis. Our analytical sample was comprised of 170,011 Maryland patients, 78,171 patients in the pre-GBR group, and 91,840 patients in the post-GBR group. The pooled analysis identified modest reductions in costs [standardized mean difference (SMD) -0.34; 95% CI, -0.42, -0.25; P <0.001], complications [odds ratio (OR): 0.57; 95% CI, 0.36-0.92, P =0.02], readmission (OR: 0.78; 95% CI, 0.72-0.85, P <0.001), mortality (OR: 0.58; 95% CI, 0.47-0.72, P <0.001), and length of stay (standardized mean difference: -0.26; 95% CI, -0.32, -0.2, P <0.001) after surgery. CONCLUSIONS: Implementation of the GBR program is associated with improved outcomes and reductions in costs among Maryland patients who underwent surgical procedures. This is particularly salient given the increasing need to disseminate and scale population-based payment models that improve patient care while controlling health care costs.

Textbook outcomes in DIEP flap breast reconstruction: a Delphi study to establish consensus.

PURPOSE: Composite measures, like textbook outcomes, may be superior to individual metrics when assessing hospital performance and quality of care. This study utilized a Delphi process to define a textbook outcome in DIEP flap breast reconstruction. METHODS: A two-round Delphi survey defined: (1) A textbook outcome, (2) Exclusion criteria for a study population, and (3) Respondent opinion regarding textbook outcomes. An a priori threshold of ≥ 70% agreement among respondents established consensus among the tested statements. RESULTS: Out of 85 invitees, 48 responded in the first round and 41 in the second. A textbook outcome was defined as one that meets the following within 90 days: (1) No intraoperative complications, (2) Operative duration ≤ 12 h for bilateral and ≤ 10 h for unilateral/stacked reconstruction, (3) No post-surgical complications requiring re-operation, (4) No surgical site infection requiring IV antibiotics, (5) No readmission, (6) No mortality, (7) No systemic complications, and (8) Length of stay < 5 days. Exclusion criteria for medical and surgical characteristics (e.g., BMI > 40, HgbA1c > 7) and case-volume cut-offs for providers (≥ 21) and institutions (≥ 44) were defined. Most agreed that textbook outcomes should be defined for complex plastic surgery procedures (75%) and utilized to gauge hospital performance for microsurgical breast reconstruction (77%). CONCLUSION: This Delphi study identified (1) Key elements of a textbook outcome for DIEP flap breast reconstruction, (2) Exclusion criteria for future studies, and (3) Characterized surgeon opinions regarding the utility of textbook outcomes in serving as quality metric for breast reconstruction care.

Tension Reduction With Force Modulating Tissue Bridges Reduces Wounds in Breast Surgery.

BACKGROUND: Tension on healing wounds increases the risk of dehiscence and poor or pathologic scar formation. Force modulating tissue bridges (FMTBs) represent a new class of wound closure and support devices designed to offload tension on healing wounds to improve wound healing and scar outcomes. OBJECTIVES: The study was undertaken to assess the efficacy of FMTBs to reduce the risk of wound healing complications in elective breast surgery. METHODS: One hundred twenty-two consecutive patients undergoing bilateral aesthetic breast surgery underwent intraoperative placement of FMTBs on the vertical limb closure site. A matched case-control cohort of 121 consecutive patients was established for comparison. Wounds were considered significant if larger than 3 mm in diameter. The primary outcome of breast wounds >3 mm was reported with a relative risk, and all outcomes were framed with number needed to treat. RESULTS: The control and intervention cohorts had similar demographics, comorbidities, type of operation, and incision pattern utilized. Within the FMTB group, 96.7% (n = 118) patients completed treatment per protocol. Significant wounds occurred in 1.7% (n = 2) of patients in the tissue bridge vs 15.2% (n = 19) in controls on a per patient/per protocol basis (89% reduction, P < .001). Statistically significant improvements were maintained on sensitivity analyses with intention to treat, even when minor wounds were included. There were no complications noted related to FMTBs. CONCLUSIONS: FMTBs are safe and highly effective at reducing the risk of wound formation in elective breast surgery. Results are consistent with sensitivity analyses based on clinical and methodological factors. Further research will assess long-term scar outcomes.

Postoperative Mechanomodulation Decreases T-Junction Dehiscence After Reduction Mammaplasty: Early Scar Analysis From a Randomized Controlled Trial.

BACKGROUND: Soft tissue and cutaneous tension is an important contributor to complicated wound healing and poor scar cosmesis after surgery and its mitigation is a key consideration in aesthetic and reconstructive procedures. OBJECTIVES: The study objective was to assess the efficacy of the force modulating tissue bridge (FMTB) ("Brijjit", Brijjit Medical Inc., Atlanta, GA) in reducing mechanical tension on postoperative wounds. METHODS: A prospective, single-center, randomized, within-subject clinical trial was conducted to evaluate wound healing and nascent scar formation after 8 weeks of postoperative wound support with the FMTB. Patients received standard of care (SOC) subcuticular closure on the vertical incision of 1 breast and experimental closure with the FMTB on the contralateral incision after Wise-pattern reduction mammaplasty. Three-dimensional wound analysis and rates of T-junction dehiscence were evaluated by clinical assessment at 2, 4, 6, and 8 weeks postsurgery. RESULTS: Thirty-four patients (n = 68 breasts) completed 8 weeks of postoperative FMTB application. There was a reduced rate of T-junction wound dehiscence in FMTB breasts (n = 1) vs SOC breasts (n = 11) (P < .01). The mean vertical incision wound area during the intervention period was significantly decreased in the FMTB breast (1.5 cm2) vs the SOC breast (2.1 cm2) (P < .01) and was significantly lower at 2-, 4-, and 8-week follow-up (P < .01). Only the closure method was significantly associated with variations in Week 8 wound area (P < .01) after linear regression modeling. CONCLUSIONS: FMTBs decrease nascent scar dimensions and reduce the occurrence of wound dehiscence. This study provides evidence that the use of continuous mechanomodulation significantly reduces postoperative wound complications after skin closure.

Outcomes and technical modifications of vascularized lymph node transplantation from the lateral thoracic region for treatment of lymphedema.

BACKGROUND AND OBJECTIVES: This study evaluates clinical outcomes of vascularized lymph node transplantation (VLNT) from the lateral thoracic region and technical modifications. METHODS: Consecutive patients that underwent lateral thoracic VLNT to treat extremity lymphedema were included. Demographic and treatment data were recorded, and outcomes data including limb volume, LDex score, and Lymphedema Life Impact Scale (LLIS), QuickDASH, and LEFS questionnaires, were collected prospectively. Consecutive patients that underwent single-photon emission computed tomography (SPECT/CT) lymphoscintigraphy axillary reverse lymphatic mapping (RLM) were analyzed to characterize the physiological drainage of the normal upper extremity. RESULTS: A consecutive series of 32 flaps were included. At 24 months postoperatively mean reduction in limb volume excess was 47.2% (±11.6; p = 0.0085), LDex score was 63.1% (±8.5; p < 0.001), and LLIS score was 65.1% (±7.4; p < 0.001). Preoperatively 14/31 patients (45.2%) reported cellulitis, and postoperatively there were no episodes at up to 24 months (p < 0.001). No patient developed donor extremity lymphedema at mean 18.6 (±8.3) months follow-up. SPECT/CT-RLM of 182 normal axillae demonstrated that the sentinel lymph node(s) of the upper extremity was consistently anatomically located in the upper outer quadrant of the axilla (97%). CONCLUSIONS: VLNT from the lateral thoracic region is effective and versatile for the treatment of lymphedema with a low donor site complication rate.

Evaluation of "Spin" in the Abstracts of Systematic Reviews and Meta-analyses of Therapeutic Interventions Published in High-Impact Plastic Surgery Journals: A Systematic Review.

BACKGROUND: "Spin" is a form of reporting bias where there is an misappropriated presentation of study results, often overstating efficacy or understating harms. Abstracts of systematic reviews in other clinical domains have been demonstrated to employ spin, which may lead to clinical recommendations that are not justified by the literature. OBJECTIVES: The objective of this study was to determine the prevalence of spin strategies in abstracts of plastic surgery systematic reviews. METHODS: A literature search was conducted using MEDLINE, Embase, and CENTRAL, to identify all systematic reviews published in the top five plastic surgery journals from 2015-2021. Screening, data extraction, and spin analysis were performed by two independent reviewers. Data checking of the spin analysis was performed by a plastic surgery resident with graduate level training in clinical epidemiology. RESULTS: From an initial search of 826 systematic reviews, 60 systematic reviews and meta-analyses were included in this study. Various types of spin were identified in 73% of systematic review abstracts (n=44). "Conclusion claims the beneficial effect of the experimental treatment despite high risk of bias in primary studies," was the most prevalent type of spin and was identified in 63% of systematic reviews (n=38). There were no significant associations between the presence of spin and study characteristics. CONCLUSIONS: The present study found that 73% of abstracts in plastic surgery systematic reviews contain spin. Although systemic reviews represent the highest level of evidence, readers should be aware of types of "spin" when interpreting results and incorporating recommendations into patient care.

Anatomy and physiology of the sentinel lymph nodes of the upper extremity: Implications for axillary reverse mapping in breast cancer.

BACKGROUND: This study characterizes the physiological drainage of the normal upper extremity using single-photon emission computed tomography/computed tomography (SPECT/CT) lymphoscintigraphy axillary reverse lymphatic mapping (ARM). METHODS: A consecutive series of patients assessed with SPECT/CT lymphoscintigraphy ARM of the upper extremity were included. Anatomical localization of the axillary sentinel lymph nodes (SLN) was completed in normal axillae in relation to consistent anatomic landmarks. Retrospective case note analysis was performed to collect patient demographic data. RESULTS: A total of 169 patients underwent SPECT/CT lymphoscintigraphy, and imaging of 182 normal axillae was obtained. All patients (100%) had an axillary SLN identified: 19% had a single contrast-enhanced SLN in the axilla and the remainder had multiple. The SLN(s) of the upper extremity was located in the upper outer quadrant (UOQ) of the axilla in 97% of cases (177 axillae). When the SLN(s) was found in the UOQ of the axilla, second-tier lymph nodes were found predominantly in the upper inner quadrant (50% of cases). CONCLUSIONS: The upper extremity SLN(s) is located in a constant region of the axilla. This study provides the most complete investigation to date and results can be directly applied clinically to ARM techniques and adjuvant radiation planning.

Managing postoperative pain in adult outpatients: a systematic review and meta-analysis comparing codeine with NSAIDs.

BACKGROUND: Analgesics that contain codeine are commonly prescribed for postoperative pain, but it is unclear how they compare with nonopioid alternatives. We sought to compare the effectiveness of codeine and nonsteroidal anti-inflammatory drugs (NSAIDs) for adults who underwent outpatient surgery. METHODS: We conducted a systematic review and meta-analysis of randomized controlled trials comparing codeine and NSAIDs for postoperative pain in outpatient surgery. We searched MEDLINE and Embase from inception to October 2019 for eligible studies. Our primary outcome was the patient pain score, converted to a standard 10-point intensity scale. Our secondary outcomes were patient-reported global assessments and adverse effects. We used random-effects models and grading of recommendations assessment, development and evaluation (GRADE) to assess the quality of evidence. RESULTS: Forty studies, including 102 trial arms and 5116 patients, met inclusion criteria. The studies had low risk of bias and low-to-moderate heterogeneity. Compared with codeine, NSAIDs were associated with better pain scores at 6 hours (weighted mean difference [WMD] 0.93 points, 95% confidence interval [CI] 0.71 to 1.15) and at 12 hours (WMD 0.79, 95% CI 0.38 to 1.19). Stronger NSAID superiority at 6 hours was observed among trials where acetaminophen was coadministered at equivalent doses between groups (WMD 1.18, 95% CI 0.87 to 1.48). NSAIDs were associated with better global assessments at 6 hours (WMD -0.88, 95% CI -1.04 to -0.72) and at 24 hours (WMD -0.67, 95% CI -0.95 to -0.40), and were associated with fewer adverse effects, including bleeding events. INTERPRETATION: We found that adult outpatients report better pain scores, better global assessments and fewer adverse effects when their postoperative pain is treated with NSAIDs than with codeine. Clinicians across all specialties can use this information to improve both pain management and opioid stewardship.

The evaluation and management of neonatal brachial plexus palsy.

Neonatal brachial plexus palsy presents at birth and can be a debilitating condition with long-term consequences. Presentation at birth depends on the extent of nerve injury, and can vary from transient weakness to global paresis, with active range of motion affected. Serial clinical examination after birth and during the neonatal period (first month of life) is crucial to assess recovery and predicts long-term outcomes. This position statement guides the evaluation of neonates for risk factors at birth, early referral to a multidisciplinary specialized team, and ongoing communication between community providers and specialists to optimize childhood outcomes.

L'évaluation et la prise en charge de la paralysie néonatale du plexus brachial.

La paralysie néonatale du plexus brachial, qui se manifeste à la naissance, peut être débilitante et avoir des conséquences prolongées. La présentation à la naissance dépend de l'importance de la lésion nerveuse et peut varier entre une faiblesse transitoire et une parésie globale qui touche l'amplitude active des mouvements. Il est essentiel de procéder à des examens cliniques sériels après la naissance et pendant la période néonatale (jusqu'à l'âge d'un mois) pour évaluer le rétablissement et prédire le pronostic à long terme. Le présent document de principes décrit l'évaluation des facteurs de risque des nouveau-nés à la naissance, l'orientation précoce vers une équipe multidisciplinaire spécialisée et les communications entre les intervenants communautaires et les spécialistes pour optimiser le pronostic pendant l'enfance.

US FDA Breast Implant Postapproval Studies: Long-term Outcomes in 99,993 Patients.

OBJECTIVE: To analyze the long-term safety and efficacy outcomes of patients with breast implants. SUMMARY BACKGROUND DATA: Research is ongoing regarding the safety of silicone breast implants. Despite the number of patients with breast implants followed by United States Food and Drug Administration large postapproval studies (LPAS), this database has not been thoroughly analyzed or reported. METHODS: This is a multicentered, cohort study. LPAS prospectively monitor long-term implant-related outcomes and systemic harms for silicone/saline implants from 2 manufacturers (Allergan and Mentor) placed for primary/revision augmentation/reconstruction. Systemic harms, self-harm, and reproductive outcomes are compared with normative data. Implant-related complications are analyzed by implant composition and operative indication in the short and long terms. RESULTS: LPAS data includes 99,993 patients, 56% of implants were silicone for primary augmentation. Long-term magnetic resonance imaging surveillance is under 5%. Compared with normative data, silicone implants are associated with higher rates of Sjogren syndrome (Standardized incidence ratio [SIR]8.14), scleroderma (SIR 7.00), rheumatoid arthritis (SIR5.96), stillbirth (SIR4.50), and melanoma (SIR3.71). One case of BI-ALCL is reported. There is no association with suicide. In the short term, rupture is higher for saline (2.5% vs. 0.5%, P < 0.001), and capsular contracture higher for silicone (5.0% vs. 2.8%, P < 0.001). At 7 years, reoperation rate is 11.7% for primary augmentation, and 25% for primary/revision reconstruction. Capsular contracture (III/IV) occurs in 7.2% of primary augmentations, 12.7% primary reconstructions, and is the most common reason for reoperation among augmentations. CONCLUSIONS: This is the largest study of breast implant outcomes. Silicone implants are associated with an increased risk of certain rare harms; associations need to be further analyzed with patient-level data to provide conclusive evidence. Long-term safety and implant-related outcomes should inform patient and surgeon decision-making when selecting implants.

Enhanced recovery after surgery (ERAS) pathways in breast reconstruction: systematic review and meta-analysis of the literature.

PURPOSE: Enhanced recovery after surgery (ERAS) pathways are increasingly promoted in post-mastectomy reconstruction, with several articles reporting their benefits and safety. This meta-analysis appraises the evidence for ERAS pathways in breast reconstruction. METHODS: A systematic search of Medline, EMBASE, and Cochrane databases was performed to identify reports of ERAS protocols in post-mastectomy breast reconstruction. Two reviewers screened studies using predetermined inclusion criteria. Studies evaluated at least one of the following end-points of interest: length of stay (LOS), opioid use, or major complications. Risk of bias was assessed for each study. Meta-analysis was performed via a mixed-effects model to compare outcomes for ERAS versus traditional standard of care. Surgical techniques were assessed through subgroup analysis. RESULTS: A total of 260 articles were identified; 9 (3.46%) met inclusion criteria with a total of 1191 patients. Most studies had "fair" methodological quality and incomplete implementation of ERAS society recommendations was noted. Autologous flaps comprised the majority of cases. In autologous breast reconstruction, ERAS significantly reduces opioid use [Mean difference (MD) = - 183.96, 95% CI - 340.27 to 27.64, p = 0.02) and LOS (MD) = - 1.58, 95% CI - 1.99 to 1.18, p < 0.00001] versus traditional care. There is no significant difference in the incidence of complications (major complications, readmission, hematoma, and infection). CONCLUSION: ERAS pathways significantly reduce opioid use and length of hospital stay following autologous breast reconstruction without increasing complication rates. This is salient given the current US healthcare climate of rising expenditures and an opioid crisis.

Brachial Plexus Birth Injury in Elective Versus Emergent Caesarean Section: A Cohort Study.

OBJECTIVE: Although Caesarean section (CS) is protective for brachial plexus birth injury (BPBI), the incidence is not zero. A trial of labour with unfavourable intrauterine positioning is hypothesized to result in excessive force on the brachial plexus. The purpose of this study was to determine the risk of BPBI in emergent CS versus elective CS. METHODS: This was a retrospective cohort study. The authors used a nationwide demographic sample of all infants born in Canada from 2004 to 2012. BPBI diagnoses, risk factors, and national incidence data were obtained from the Canadian Institute for Health Information Discharge Abstract Database and Hospital Morbidity Database. The primary outcome was risk of BPBI in emergent CS versus elective CS. RESULTS: BPBI incidence was 1.24 per 1000 live births. Known biases may have underestimated the incidence. CS (elective and emergent) was protective for BPBI as compared with vaginal delivery (odds ratio [OR] 0.15; 95% confidence interval [CI] 0.13-0.18, P < 0.0001). Emergent CS was a moderately strong risk factor for BPBI versus elective CS (OR 3.14; 95% CI 1.79-5.10, P = 0.0001). CONCLUSION: Emergent CS is a moderate risk factor for BPBI compared with elective CS. Intrauterine positioning with a trial of labour may provide an antenatal etiology in these distinct cases.

Adjunctive Dorsal Scapular Nerve Transfer to Suprascapular Nerve for Brachial Plexus Birth Injuries: Case Series.

PURPOSE: Brachial plexus birth injury (BPBI) may result in permanent functional deficits. Brachial plexus birth injury involving the suprascapular nerve (SSN) is conventionally treated using accessory nerve transfer or excision and nerve grafting. This study analyzed shoulder function in patients with BPBI undergoing dorsal scapular nerve (DSN) to SSN transfer. METHODS: We performed a retrospective review of all infants referred to the McMaster University Children's Hospital for BPBI between 1999 and 2012. Patients were included if they underwent SSN reconstruction with DSN transfer and functional outcomes were recorded as measured by the active movement scale (AMS). RESULTS: Of the 266 patients referred, 16 met inclusion criteria. From the initial assessment to final follow-up, average AMS scores improved by 4.1 and 4.4 points for shoulder abduction and external rotation, respectively. In addition, 50% of patients had shoulder abduction greater than half of full range of motion and 43% had external rotation greater than half of full range of motion (AMS scores of 6 or greater). No patient had a secondary surgery; however, 9 of 16 had subsequent botulinum toxin injections. CONCLUSIONS: Although DSN to SSN nerve transfers were combined with other interventions and the outcomes cannot be attributed solely to this nerve transfer alone, it presents an alternative approach to SSN reinnervation under circumstances in which the accessory nerve is unavailable, damaged, or suboptimal. Successful results were achieved; thus, further exploration and study are warranted. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Reduced venous thrombosis and re-exploration time with anastomotic coupling device: A cohort study.

OBJECTIVE: In the anastomotic coupling device literature, no comparative study has reported operative times, included consecutive patients, or used a matched comparison group. Our objective was to analyze patency and operative time in free flaps with venous anastomoses performed with ACD versus hand-sewn. METHODS: For consecutive free flaps, re-explorations and complications were reviewed in duplicate. Operative times for ACD versus hand-sewn were compared for: (1) matched unilateral DIEPs, and (2) re-explorations. RESULTS: Overall, 147 ACD and 144 hand-sewn flaps were included. Venous thrombosis was significantly lower with ACD (1/147[1%] vs.9/144[6%], P < 0.01). There was no difference in re-exploration for venous insufficiency, or overall re-exploration. Re-exploration time was significantly shorter with ACD (69mins vs.205mins, P = 0.009). CONCLUSIONS: ACD significantly decreases venous thrombosis compared to hand-sewn veins, and significantly shortens re-exploration time. Outcomes allow an estimate of cost utility for the ACD in decreasing venous thromboses and shortening re-exploration time. © 2015 Wiley Periodicals, Inc. Microsurgery 36:372-377, 2016.
