Subpectoral Implant Placement Is Not Protective against Postmastectomy Radiotherapy-Related Complications Compared to Prepectoral Placement.

BACKGROUND: Postmastectomy radiotherapy (PMRT) is associated with altered cosmetic outcomes and higher complication rates in implant-based breast reconstruction (IBR). Conventional wisdom suggests that muscle coverage is somewhat protective against PMRT-related complications. In this study, the authors compared surgical outcomes in patients who underwent two-stage prepectoral versus subpectoral IBR in the setting of PMRT. METHODS: The authors performed a retrospective cohort study of patients who underwent mastectomy and PMRT with two-stage IBR from 2016 to 2019. The primary outcome was breast-related complications, including device infection; the secondary outcome was device explantation. RESULTS: The authors identified 179 reconstructions (101 prepectoral and 78 subpectoral) in 172 patients with a mean follow-up time of 39.7 ± 14.4 months. There were no differences between the prepectoral and subpectoral reconstructions in rates of breast-related complications (26.7% and 21.8%, respectively; P = 0.274), device infection (18.8% and 15.4%, respectively; P = 0.307), skin flap necrosis (5.0% and 1.3%, respectively; P = 0.232), or device explantation (20.8% and 14.1%, respectively; P = 0.117). In adjusted models, compared with prepectoral device placement, subpectoral device placement was not associated with a lower risk of breast-related complications [hazard ratio (HR), 0.75; 95% confidence interval (CI), 0.41 to 1.36], device infection (HR, 0.73; 95% CI, 0.35 to 1.49), or device explantation (HR, 0.58; 95% CI, 0.28 to 1.19). CONCLUSIONS: Device placement plane was not predictive of complication rates in IBR in the setting of PMRT. Two-stage prepectoral IBR provides safe long-term outcomes with acceptable postoperative complication rates comparable to those with subpectoral IBR, even in the setting of PMRT. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Outcomes for 160 Consecutive Lateral Arm Free Flaps for Head and Neck Reconstruction.

OBJECTIVE: Examine outcomes for lateral arm autologous tissue transfer in head and neck reconstruction. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary cancer center. METHODS: All patients who underwent traditional lateral arm, extended lateral arm, and lateral forearm flaps for head and neck reconstruction from 2012 to 2022 were assessed. Disabilities of the arm, shoulder, and hand (DASH) was measured. Factors associated with complications and enteral or mixed diet were evaluated by multivariable regression. RESULTS: Among 160 patients followed for a median of 2.3 ± 2.1 years, defects were 54% oral tongue, 18% external, 9% maxilla, 8% buccal mucosa, 9% floor of mouth, and 3% pharynx. Flap types (and median pedicle lengths) were 41% traditional lateral arm (8 cm), 25% extended lateral arm (11.5 cm), and 34% lateral forearm (14 cm). All donor sites were closed primarily; 19.6% and 0% of patients had increased DASH scores 2 and 12 weeks after reconstruction. Major complications occurred in 18.1% of patients, including 6.3% reoperation, 6.9% readmission, 3.7% fistula, and 1.8% flap loss. Complications were independently associated with peripheral vascular disease (odds ratio [OR]: 5.71, 95% confidence interval [CI]: 1.5-21.6, P = .01), pharyngeal defects (OR: 11.3, 95% CI: 1.4-94.5, P = .025), and interposition vein grafts (OR: 3.78, 95% CI: 1.1-13.3, P = .037). CONCLUSION: The lateral arm free flap was safe, versatile, and reliable for head and neck reconstruction with low donor-site morbidity. Complications occurred in a fifth of patients and were associated with peripheral vascular disease, pharyngeal defects, and vein grafts.

Frail but Resilient: Frailty in Autologous Breast Reconstruction is Associated with Worse Surgical Outcomes but Equivalent Long-Term Patient-Reported Outcomes.

BACKGROUND: Frailty is associated with higher risk of complications following breast reconstruction, but its impact on long-term surgical and patient-reported outcomes has not been investigated. We examined the association of the five-item modified frailty index (MFI) score with long-term surgical and patient-reported outcomes in autologous breast reconstruction. PATIENTS AND METHODS: We conducted a retrospective cohort study of consecutive patients who underwent mastectomy and autologous breast reconstruction between January 2016 and April 2022. Primary outcome was any flap-related complication. Secondary outcomes were patient-reported outcomes and predictors of complications in the frail cohort. RESULTS: We identified 1640 reconstructions (mean follow-up 24.2 ± 19.2 months). In patients with MFI ≥ 2, the odds of surgical [odds ratio (OR) 2.13, p = 0.023] and medical (OR 17.02, p < 0.001) complications were higher than in nonfrail patients. We found no significant difference in satisfaction with the breast (p = 0.287), psychosocial well-being (p = 0.119), or sexual well-being (p = 0.314) according to MFI score. Chronic obstructive pulmonary disease was an independent predictor of infection (OR 3.70, p = 0.002). Tobacco use (OR 7.13, p = 0.002) and contralateral prophylactic mastectomy (OR 2.36, p = 0.014) were independent predictors of wound dehiscence. Dependent functional status (OR 2.36, p = 0.007) and immediate reconstruction (compared with delayed reconstruction; OR 3.16, p = 0.026) were independent predictors of skin flap necrosis. Dependent functional status was also independently associated with higher odds of reoperation (OR 2.64, p = 0.011). CONCLUSION: Frailty is associated with higher risk of complications in breast reconstruction, but there is no significant difference in long-term patient-reported outcomes. MFI should be considered in breast reconstruction to improve outcomes in high-risk frail patients.

Surgical Outcomes of Vertical Rectus Abdominis Myocutaneous Flap Pelvic Reconstruction.

BACKGROUND: The vertical rectus abdominis myocutaneous (VRAM) flap has emerged as the workhorse flap for perineal and pelvic reconstruction. We aimed to evaluate outcomes of VRAM flap over a 20-year period and the role of mesh abdominal wall reinforcement following VRAM flap-based reconstruction. METHODS: We conducted a retrospective review of all consecutive patients who underwent pelvic reconstruction with a VRAM flap between January 2001 and March 2021. Our primary outcome measure included recipient and donor surgical site occurrences (SSOs). RESULTS: We identified a total of 546 patients (55% females) with a mean age was 58 years and mean BMI was 27 kg/m 2. Mesh was used at the time of VRAM reconstruction to reinforce the abdominal donor site in 36% of patients. Recipient-site SSOs occurred in 38% of patients while donor-site SSOs occurred in 17% of patients. Hernia was identified in 9.9% of patients while bulge developed in 6.4% of patients. Cox proportional hazards regression model for hernia occurrence identified age, BMI, tobacco use (HR 2.03, 95% CI [1.02 - 4.04]) and use as an extended VRAM (HR 2.13, 95% CI [1.04 - 4.36]). The use of mesh or component separation were not independent protective factors for hernia occurrence. CONCLUSION: The pedicled VRAM flap is versatile and is our preferred flap for reconstruction of pelvic and perineal defects. The use of mesh/component separation to allow for fascial closure was not shown to reduce donor site hernia occurrence.

Outcomes of Complex Abdominal Wall Reconstruction with Biologic Mesh in Patients with 8 Years of Follow-Up.

BACKGROUND: While many studies evaluated outcomes of abdominal wall reconstruction with biologic mesh, long-term data is lacking. In this study, we sought to analyze the outcomes of complex AWR with biologic mesh in a robust cohort of patients with a mean follow up of 8 years. METHODS: We conducted a longitudinal study of AWR patients from 2005 to 2019. Hernia recurrence was the primary outcome, and surgical site occurrence was the secondary outcome. Predictive/protective factors were identified using a Cox proportional hazards regression models. RESULTS: We identified 109 consecutive patients who met the inclusion criteria. Patient's mean (± SD) age was 57.5 ± 11.8 years, mean body mass index was 30.7 ± 7.2 kg/m2, and mean follow-up time was 96.2 ± 15.9 months. Fifty-six percent had clean defects, 34% had clean-contaminated defects, and 10% had contaminated/infected defects. Patients had a mean defect size of 261 ± 199.6 cm2 and mean mesh size of 391.3 ± 160.2 cm2. Nineteen patients (17.4%) developed HR at the final follow-up date. Obesity was independently associated with a four-fold higher risk of HR (hazard ratio, 3.98; 95%CI, 1.34 to 14.60, p = 0.02). SSOs were identified in 24.8% of patients. A prior hernia repair was associated with a three-fold higher risk of SSOs (Odds ratio, 3.13; 95%CI, 1.10 to 8.94, p = 0.03). No patient developed mesh infection. CONCLUSION: These longitudinal data demonstrate that complex AWR with biologic mesh provides long-term durable outcomes with acceptable HR and SSO rates despite high contamination levels, patients complexity, and large defect size.

The Skin Necrosis Conundrum: Examining Long-term Outcomes and Risk Factors in Implant-Based Breast Reconstruction.

BACKGROUND: Mastectomy skin flap necrosis (MSFN) is a common complication following mastectomy that causes significant distress to patients and physicians and also compromises oncologic, surgical, and quality-of-life outcomes. OBJECTIVES: We sought to investigate the long-term outcomes of MSFN following implant-based reconstruction (IBR) and determine the rates and predictors of post-MSFN complications. METHODS: This was a 20-year analysis of consecutive adult (>18 years) patients who developed MSFN following mastectomy and IBR from January 2001 to January 2021. Multivariable analyses were performed to identify factors associated with post-MSFN complications. RESULTS: We identified 148 reconstructions, with a mean follow-up time of 86.6 ± 52.9 months. The mean time from reconstruction to MSFN was 13.3 ± 10.4 days, and most cases (n = 84, 56.8%) were full-thickness injuries. Most cases (63.5%) were severe, 14.9% were moderate, and 21.6% were mild. Forty-six percent (n = 68) developed a breast-related complication, with infection being the most common (24%). An independent predictor of overall complications was longer time from reconstruction to MSFN (odds ratio [OR], 1.66; P = .040). Aging was an independent predictor of overall complications (OR, 1.86; P = .038); infection (OR, 1.72; P = .005); and dehiscence (OR, 6.18; P = .037). Independent predictors of dehiscence were longer interval from reconstruction to MSFN (OR, 3.23; P = .018) and larger expander/implant size (OR, 1.49; P = .024). Independent predictors of explantation were larger expander/implant size (OR, 1.20; P = .006) and nipple-sparing mastectomy (OR, 5.61; P = .005). CONCLUSIONS: MSFN is associated with high risk of complications following IBR. Awareness of the timing and severity of MSFN and the predictors of post-MSFN complications is crucial for guiding evidence-based decision-making and improving outcomes.

Long-term Surgical and Patient-Reported Outcomes Comparing Skin-Preserving, Staged Versus Delayed Microvascular Breast Reconstruction.

BACKGROUND: Skin-preserving, staged, microvascular, breast reconstruction often is preferred in patients requiring postmastectomy radiotherapy (PMRT) but may lead to complications. We compared the long-term surgical and patient-reported outcomes between skin-preserving and delayed microvascular breast reconstruction with and without PMRT. METHODS: We conducted a retrospective, cohort study of consecutive patients who underwent mastectomy and microvascular breast reconstruction between January 2016 and April 2022. The primary outcome was any flap-related complication. The secondary outcomes were patient-reported outcomes and tissue-expander complications. RESULTS: We identified 1002 reconstructions (672 delayed; 330 skin-preserving) in 812 patients. Mean follow-up was 24.2 ± 19.3 months. PMRT was required in 564 reconstructions (56.3%). In the non-PMRT group, skin-preserving reconstruction was independently associated with shorter hospital stay (ß - 0.32, p = 0.045) and lower odds of 30-days readmission (odds ratio [OR] 0.44, p = 0.042), seroma (OR 0.42, p = 0.036), and hematoma (OR 0.24, p = 0.011) compared with delayed reconstruction. In the PMRT group, skin-preserving reconstruction was independently associated with shorter hospital stay (ß - 1.15, p < 0.001) and operative time (ß - 97.0, p < 0.001) and lower odds of 30-days readmission (OR 0.29, p = 0.005) and infection (OR 0.33, p = 0.023) compared with delayed reconstruction. Skin-preserving reconstruction had a 10.6% tissue expander loss rate and did not differ from delayed reconstruction in terms of patient-reported satisfaction with breast, psychosocial well-being, or sexual well-being. CONCLUSIONS: Skin-preserving, staged, microvascular, breast reconstruction is safe regardless of the need for PMRT, with an acceptable tissue expander loss rate, and is associated with improved flap outcomes and similar patient-reported quality of life to that of delayed reconstruction.

Outcomes of Targeted Muscle Reinnervation and Regenerative Peripheral Nerve Interfaces for Chronic Pain Control in the Oncologic Amputee Population.

BACKGROUND: Outcomes of targeted muscle reinnervation (TMR) and regenerative peripheral nerve interface (RPNI) in the oncologic population are limited. We sought to examine the safety and effectiveness of TMR and RPNI in controlling postamputation pain in the oncologic population. STUDY DESIGN: A retrospective cohort study of consecutive patients who underwent oncologic amputation followed by immediate TMR or RPNI was conducted from November 2018 to May 2022. The primary study outcome was postamputation pain, assessed using the Numeric Pain Scale and Patient-Reported Outcomes Measurement Information System (PROMIS) for residual limb pain (RLP) and phantom limb pain (PLP). Secondary outcomes included postoperative complications, tumor recurrence, and opioid use. RESULTS: Sixty-three patients were evaluated for a mean follow-up period of 11.3 months. The majority of patients (65.1%) had a history of previous limb salvage. At final follow-up, patients had an average Numeric Pain Scale score for RLP of 1.3 ± 2.2 and for PLP, 1.9 ± 2.6. The final average raw PROMIS measures were pain intensity 6.2 ± 2.9 (T-score 43.5), pain interference 14.6 ± 8.3 (T-score 55.0), and pain behavior 39.0 ± 22.1 (T-score 53.4). Patient opioid use decreased from 85.7% preoperatively to 37.7% postoperatively and morphine milligram equivalents decreased from a mean of 52.4 ± 53.0 preoperatively to 20.2 ± 38.4 postoperatively. CONCLUSIONS: In the oncologic population TMR and RPNI are safe surgical techniques associated with significant reductions in RLP, PLP, and improvements in patient-reported outcomes. This study provides evidence for the routine incorporation of TMR and RPNI in the multidisciplinary care of oncologic amputees.

Impact of Obesity on Outcomes of Prepectoral vs Subpectoral Implant-Based Breast Reconstruction.

BACKGROUND: The impact of obesity on outcomes of prepectoral vs subpectoral implant-based reconstruction (IBR) is not well-established. OBJECTIVES: The goal of this study was to assess the surgical and patient-reported outcomes of prepectoral vs subpectoral IBR. The authors hypothesized that obese patients would have similar outcomes regardless of device plane. METHODS: We conducted a retrospective review of obese patients who underwent 2-stage IBR from January 2017 to December 2019. The primary endpoint was the occurrence of any breast-related complication; the secondary endpoint was device explantation. RESULTS: The authors identified a total of 284 reconstructions (184 prepectoral, 100 subpectoral) in 209 patients. Subpectoral reconstruction demonstrated higher rates of overall complications (50% vs 37%, P = .047) and device explantation (25% vs 12.5%, P = .008) than prepectoral reconstruction. In multivariable regression, subpectoral reconstruction was associated with higher risk of infection (hazard ratio [HR], 1.65; P = .022) and device explantation (HR, 1.97; P = .034). Subgroup analyses demonstrated significantly higher rates of complications and explantation in the subpectoral group in those with a body mass index (BMI) ≥ 35 and BMI ≥40. The authors found no significant differences in mean scores for satisfaction with the breast (41.57 ± 13.19 vs 45.50 ± 11.91, P = .469), psychosocial well-being (39.43 ± 11.23 vs 39.30 ± 12.49, P = .915), and sexual well-being (17.17 ± 7.83 vs 17.0 ± 9.03, P = .931) between subpectoral and prepectoral reconstruction. CONCLUSIONS: Prepectoral reconstruction was associated with significantly decreased overall complications, infections, and device explantation in obese patients compared with subpectoral reconstruction. Prepectoral reconstruction provides superior outcomes to subpectoral reconstruction with comparable patient-reported outcomes.

A nationwide cross-sectional study on the association of patient-level factors with financial anxiety in the context of chronic medical conditions.

Patient-level characteristics associated with the prevalence and severity of financial anxiety have yet to be described. We conducted a cross-sectional analysis of survey data assessing financial anxiety in patients with chronic medical conditions in December 2020. 1771 patients (42.6% response rate) participated in the survey. Younger age (19-35 age compared to ≥ 75 age) (ß, 5.86; 95% CI 2.10-9.63), male sex (ß, - 1.9; 95% CI - 3.1 to - 0.73), Hispanic/Latino race/ethnicity (compared with White patients) (ß, 2.55; 95% CI 0.39-4.71), household size ≥ 4 (compare with single household) (ß, 4.54; 95% CI 2.44-6.64), household income of ≥ $96,000-$119,999 (compared with ≤ $23,999) (ß, - 3.2; 95% CI - 6.3 to 0.04), single marital status (compared with married) (ß, 2.18; 95% CI 0.65-3.71), unemployment (ß, 2.07; 95% CI 0.39-3.74), high-school education (compared with advanced degrees) (ß, 3.10; 95% CI 1.32-4.89), lack of insurance coverage (compared with private insurance) (ß, 6.05; 95% CI 2.66-9.45), more comorbidities (≥ 3 comorbidities compared to none) (ß, 2.95; 95% CI 1.00-4.90) were all independently associated with financial anxiety. Patients who are young, female, unmarried, and representing vulnerable sub-populations are at elevated risk for financial anxiety.

Decoding the Mastectomy SKIN Score: An Evaluation of Its Predictive Performance in Immediate Breast Reconstruction.

BACKGROUND: The skin ischemia and necrosis (SKIN) score was introduced to standardize the assessment of mastectomy skin flap necrosis (MSFN) severity and the need for reoperation. We evaluated the association between the SKIN score and the long-term postoperative outcomes of MSFN after mastectomy and immediate breast reconstruction (IBR). METHODS: We conducted a retrospective cohort study of consecutive patients who developed MSFN following mastectomy and IBR from January 2001 to January 2021. Primary outcome was breast-related complications following MSFN. Secondary outcomes were 30-day readmission, operating room (OR) debridement, and reoperation. Study outcomes were correlated with the SKIN composite score. RESULTS: We identified 299 reconstructions in 273 consecutive patients with mean follow-up time of 111.8±3.9 months. Most patients had a composite SKIN score of B2 (25.0%, n=13), followed by D2 (17.3%) and C2 (15.4%). We found no significant difference in rates of OR debridement (p=0.347), 30-day readmission (p=0.167), any complication (p=0.492), or reoperation for a complication (p=0.189) based on the SKIN composite score. The composite skin score was a poor predictor of reoperation, with area under the curve (AUC) of 0.56. A subgroup analysis in patients who underwent implant-based reconstruction revealed no difference in rates of OR debridement (p=0.986), 30-day readmission (p=0.530), any complication (p=0.492), or reoperation for a complication (p=0.655) based on the SKIN composite score. CONCLUSION: The SKIN score was a poor predictor for postoperative MSFN outcomes and reoperation. An individualized risk-assessment tool that incorporates both the anatomical appearance of the breast, imaging data, and patient-level risk factors is needed.

Ensuring Safety While Achieving Beauty: An Evidence-Based Approach to Optimizing Mastectomy and Autologous Breast Reconstruction Outcomes in Patients with Obesity.

BACKGROUND: Although obesity has previously been associated with poor outcomes after mastectomy and breast reconstruction, its impact across the WHO obesity classification spectrum and the differential effects of various optimization strategies on patient outcomes have yet to be delineated. We sought to examine the impact of WHO obesity classification on intraoperative surgical and medical complications, postoperative surgical and patient-reported outcomes of mastectomy and autologous breast reconstruction, and delineate outcomes optimization strategies for obese patients. STUDY DESIGN: This is a review of consecutive patients who underwent mastectomy and autologous breast reconstruction from 2016 to 2022. Primary outcomes were complication rates. Secondary outcomes were patient-reported outcomes and optimal management strategies. RESULTS: We identified 1,640 mastectomies and reconstructions in 1,240 patients with mean follow-up of 24.2 ± 19.2 months. Patients with class II/III obesity had higher adjusted risk of wound dehiscence (odds ratio [OR] 3.20; p < 0.001), skin flap necrosis (OR 2.60; p < 0.001), deep venous thrombosis (OR 3.90; p < 0.033), and pulmonary embolism (OR 15.3; p = 0.001) than nonobese patients. Obese patients demonstrated significantly lower satisfaction with breasts (67.3 ± 27.7 vs 73.7 ± 24.0; p = 0.043) and psychological well-being (72.4 ± 27.0 vs 82.0 ± 20.8; p = 0.001) than nonobese patients. Unilateral delayed reconstructions were associated with independently shorter hospital stay (ß -0.65; p = 0.002) and lower adjusted risk of 30-day readmission (OR 0.45; p = 0.031), skin flap necrosis (OR 0.14; p = 0.031), and pulmonary embolism (OR 0.07; p = 0.021). CONCLUSIONS: Obese women should be closely monitored for adverse events and lower quality of life, offered measures to optimize thromboembolic prophylaxis, and advised on the risks and benefits of unilateral delayed reconstruction.

Comparison of Long-term Surgical Outcomes and Microsurgical Skills between Independent and Integrated Plastic Surgery Trainees.

We compared the surgical skills and outcomes of microsurgical fellows who completed an independent versus integrated plastic surgery residency. Methods: We reviewed outcomes of abdominal wall reconstructions performed autonomously by microsurgical fellows at our institution from March 2005 to June 2019; outcome measures included hernia recurrence, surgical site occurrence, surgical site infection, length of hospital stay, unplanned return to the operating room, and 30-day readmission. The microsurgical skills were prospectively evaluated using the validated Structured Assessment of Microsurgical Skills at the start and end of the fellowship, in an animal laboratory model and clinical microsurgical cases. Multivariable hierarchical models were constructed to evaluate study outcomes. Results: We identified 44 fellows and 118 consecutive patients (52% women) who met our inclusion criteria. Independent fellows performed 55% (n = 65) of cases, and 45% were performed by integrated fellows. We found no significant difference in hernia recurrence, surgical site occurrences, surgical site infections, 30-day readmission, unplanned return to the operating room, or length of stay between the two groups in adjusted models. Although laboratory scores were similar between the groups, integrated fellows demonstrated higher initial clinical scores (42.0 ± 4.9 versus 37.7 ± 5.0, P = 0.04); however, the final clinical scores were similar (50.8 ± 6.0 versus 48.9 ± 5.2, P = 0.45). Conclusions: Independent and integrated fellows demonstrated similar long-term patient outcomes. Although integrated fellows had better initial microsurgical skills, evaluation at the conclusion of fellowship revealed similar performance, indicating that fellowship training allows for further development of competent surgeons.
