Axillary Lymph Node Dissection Is a Risk Factor for Major Complications After Immediate Breast Reconstruction.

BACKGROUND: Complications after immediate breast reconstruction pose a significant challenge to the reconstructive surgeon. Known risk factors include smoking, obesity, age, and adjuvant oncologic therapies. Less is known about the association between axillary lymph node dissection (ALND) and the development of postoperative complications. METHODS: We conducted a retrospective study of all patients who underwent immediate breast reconstruction after mastectomy at our institution over a 10-year period. Our outcome was an occurrence of a major complication within 90 days postoperatively. For each patient, we recorded data on demographics, smoking status, pertinent medical history, reconstruction type, adjuvant chemotherapy and radiation, tumor pathology, and whether an ALND was performed. Odds ratios (OR) were calculated to estimate the risk of a complication if an ALND was performed. RESULTS: One hundred eighty-four women, with 270 surgically treated breasts, were identified as having mastectomy with immediate reconstruction between 2002 and 2012. Mean age was 49.4 years (range, 25-84 years). There were 71 mastectomies with ALND performed, with 22 complications, and 199 mastectomies without ALND, with 20 complications (31% complication rate vs 10%, respectively; OR, 3.84; P < 0.001). When adjusted for reconstruction type, smoking history, obesity, age, presence of invasive disease, chemotherapy, and radiation therapy, the OR for complications was 3.49 (P < 0.01). The most common complication was infection in both groups. CONCLUSIONS: Mastectomy with ALND is associated with a 3-fold increase in risk of major complications in women undergoing immediate breast reconstruction, even after adjustment for known risk factors and confounders. Further studies are warranted to elucidate how ALND leads to these complications and what measures can reduce their occurrence.

Estrogen receptor, progesterone receptor, interleukin-6 and interleukin-8 are variable in breast cancer and benign stem/progenitor cell populations.

BACKGROUND: Estrogen receptor positive breast cancers have high recurrence rates despite tamoxifen therapy. Breast cancer stem/progenitor cells (BCSCs) initiate tumors, but expression of estrogen (ER) or progesterone receptors (PR) and response to tamoxifen is unknown. Interleukin-6 (IL-6) and interleukin-8 (IL-8) may influence tumor response to therapy but expression in BCSCs is also unknown. METHODS: BCSCs were isolated from breast cancer and benign surgical specimens based on CD49f/CD24 markers. CD44 was measured. Gene and protein expression of ER alpha, ER beta, PR, IL-6 and IL-8 were measured by proximity ligation assay and qRT-PCR. RESULTS: Gene expression was highly variable between patients. On average, BCSCs expressed 10-106 fold less ERα mRNA and 10-103 fold more ERß than tumors or benign stem/progenitor cells (SC). BCSC lin-CD49f-CD24-cells were the exception and expressed higher ERα mRNA. PR mRNA in BCSCs averaged 10-104 fold less than in tumors or benign tissue, but was similar to benign SCs. ERα and PR protein detection in BCSCs was lower than ER positive and similar to ER negative tumors. IL-8 mRNA was 10-104 higher than tumor and 102 fold higher than benign tissue. IL-6 mRNA levels were equivalent to benign and only higher than tumor in lin-CD49f-CD24-cells. IL-6 and IL-8 proteins showed overlapping levels of expressions among various tissues and cell populations. CONCLUSIONS: BCSCs and SCs demonstrate patient-specific variability of gene/protein expression. BCSC gene/protein expression may vary from that of other tumor cells, suggesting a mechanism by which hormone refractory disease may occur.

A multicenter randomized controlled trial comparing absorbable barbed sutures versus conventional absorbable sutures for dermal closure in open surgical procedures.

BACKGROUND: Barbed sutures were developed to reduce operative time and improve security of wound closure. OBJECTIVE: The authors compare absorbable barbed sutures (V-Loc, Covidien, Mansfield, Massachusetts) with conventional (smooth) absorbable sutures for soft tissue approximation. METHOD: A prospective multicenter randomized study comparing barbed sutures with smooth sutures was undertaken between August 13, 2009, and January 31, 2010, in 241 patients undergoing abdominoplasty, mastopexy, and reduction mammaplasty. Each patient received barbed sutures on 1 side of the body, with deep dermal sutures eliminated or reduced. Smooth sutures with deep dermal and subcuticular closure were used on the other side as a control. The primary endpoint was dermal closure time. Safety was assessed through adverse event reporting through a 12-week follow-up. RESULTS: A total of 229 patients were ultimately treated (115 with slow-absorbing polymer and 114 with rapid-absorbing polymer). Mean dermal closure time was significantly quicker with the barbed suture compared with the smooth suture (12.0 vs 19.2 minutes; P<.001), primarily due to the need for fewer deep dermal sutures. The rapid-absorbing barbed suture showed a complication profile equivalent to the smooth suture, while the slow-absorbing barbed suture had a higher incidence of minor suture extrusion. CONCLUSIONS: Barbed sutures enabled faster dermal closure quicker than smooth sutures, with a comparable complication profile. LEVEL OF EVIDENCE: 1.

Surgeon Gender-Related Differences in Operative Coding in Plastic Surgery.

BACKGROUND: Numerous studies in the medical and surgical literature have discussed the income gap between male and female physicians, but none has adequately accounted for the disparity. METHODS: This study was performed to determine whether gender-related billing and coding differences may be related to the income gap. A 10 percent minimum difference was set a priori as statistically significant. A cohort of 1036 candidates' 9-month case lists for the American Board of Plastic Surgery over a 5-year span (2014 to 2018) was evaluated for relationships between surgeon gender and work relative value units, coding information, major and minor cases performed, and work setting. Data were deidentified by the American Board of Plastic Surgery before evaluation. The authors hypothesized that work relative value units, average codes per case, major cases, and minor cases would be at least 10 percent higher for male than for female physicians. RESULTS: Significant differences were found between male and female surgeons in work relative value units billed, work relative value units billed per case, and the numbers of major cases performed. The average total work relative value units for male surgeons was 19.34 percent higher than for female surgeons [3253.2 (95 percent CI, 3090.5 to 3425.8) versus 2624.1 (95 percent CI, 2435.2 to 2829.6)]. Male surgeons performed 14.28 percent more major cases than female surgeons [77.6 percent (95 percent CI, 72.7 to 82.7 percent) versus 90.5 percent (95 percent CI, 86.3 to 94.9 percent); p = 0.0002]. CONCLUSIONS: The authors' findings support the hypothesis that billing and coding practices can, in part, account for income differences between male and female plastic surgeons. Potential explanations include practices focusing on larger and more complex operative cases and differences in coding practices.

Full-thickness skin grafting with marginal deepithelialization of the defect for reconstruction of helical rim keloids.

Excising a keloid from the helical rim generally results in a narrow defect with exposed cartilage. Skin grafting is a surgical method with a lowest recurrence rate for keloid treatment. Full-thickness skin grafting may produce an excellent cosmetic outcome, but is generally considered too unreliable over a poorly vascularized defect with exposed cartilage. Adding a new healthy bed with rich vascularity on the periphery will increase the probability of the entire graft surviving via the bridging phenomenon. We report full-thickness skin grafting using a marginal deepithelialization technique for treatment of helical rim keloids. After keloid excision, the surrounding normal skin was deepithelialized 2 to 3 mm wide over the defect border, followed by full-thickness skin grafting. All grafts survived completely. None of the keloids recurred, and they all showed an excellent aesthetic result during the follow-up period from 9 months to 6 years.

Academics in the Pandemic: Early Impact of COVID-19 on Plastic Surgery Training Programs.

The COVID-19 global pandemic has impacted plastic surgery training in the United States, requiring unprecedented measures to prepare for potential surges in critically ill patients. This study investigates how plastic surgery programs responded to this crisis, as well as how successful these changes were, through a survey of program directors and of residents at academic training programs in the United States. METHODS: Two separate anonymous online surveys were conducted via REDCap between April 16 and June 4, 2020. The first survey was distributed to program directors, and the second was distributed to plastic surgery residents. Resident responses were then subdivided for an analysis between geographic regions. RESULTS: Of the 59 program director responses (43.7%), the majority of programs implemented a platoon approach for resident coverage. A minority did the same for attending coverage. In total, 92% transitioned to virtual didactics only. Plastic surgery residents covered alternative services at 25% of responding institutions, and an additional 68% had a plan in place for responding to personnel shortages. Overall, residents were satisfied with their program's response in a variety of categories. When subdivided based on geographic region, respondents in the Northeast and Northwest were less satisfied with resident wellness, personal and loved ones' safety, and program communication. CONCLUSIONS: With the possibility of a "second wave," successful methods of academic programs adapting to the pandemic should be communicated to reduce the future impact. Increased frequency of communications between program directors and residents can improve mental health and wellness of the resident population.

Differences in Chest Measurements between the Cis-female and Trans-female Chest Exposed to Estrogen and Its Implications for Breast Augmentation.

BACKGROUND: Gender confirming primary breast augmentation is becoming more common. The purpose of this study was to compare the demographic and anatomical differences in cis-female and trans-female populations. METHODS: This was a retrospective analysis of trans-female patients and cis-female patients undergoing primary breast augmentation at a single institution. Analysis included patient demographics and preoperative chest measurements including sternal notch to nipple distance (SSN), breast width (BW), nipple to inframammary fold distance (N-IMF), and nipple to midline distance (N-M). Continuous variables were compared using independent t tests, and discrete variables were compared using Pearson's χ2 tests. RESULTS: Eighty-two trans-female and 188 cis-female patients undergoing primary breast augmentation were included. Trans-female patients were older (40.37 versus 34.07), more likely to have psychological comorbidities (50% versus 12.23%), and had a higher body mass index, 27.46 kg/m2 versus 22.88 kg/m2 (P = 1.91E-07), than cis-female patients. Cis-female patients most commonly had an ectomorph body habitus (52% versus 26%), whereas trans-female patients most commonly had an endomorph body habitus (40% versus 7%). Pseudoptosis or ptosis was more commonly seen in cis-female patients (P = 0.0056). There were significant differences in preoperative breast measurements including sternal notch to nipple distance, BW, and N-M between groups, but not in N-IMF. The ratio of BW/N-IMF was statistically significant (P = 2.65E-07 on right), indicating that the similarity in N-IMF distance did not adjust for the difference in BW. CONCLUSIONS: The trans-female and cis-female populations seeking primary breast augmentation have significant demographic and anatomical differences. This has implications for surgical decision-making and planning to optimize outcomes for trans-female patients.

Revascularization of rat fasciocutaneous flap using CROSSEAL with VEGF protein or plasmid DNA expressing VEGF.

BACKGROUND: Fasciocutaneous tissue transfer is a common reconstructive procedure. Revascularization of flap tissue is an important component of tissue healing. Gene therapy offers an avenue through which the period of pedicle vascular dependency can be reduced. MATERIALS AND METHODS: Rat fasciocutaneous flaps were elevated and a two-hour ischemic time induced. Polycation complex (jet PEI) and human fibrin sealant CROSSEAL was applied between flap and underlying abdominal tissues. Group 1 (six rats) was the control; Group 2 (seven rats) had vascular endothelial growth factor (VEGF) protein applied; Group 3 (seven rats) had plasmid DNA expressing VEGF applied. Vascular pedicles were ligated on postoperative day 5, percentage flap survival evaluated on day 7. RESULTS: All flaps survived initial ischemia. Mean +/- SD percentage area of the flap that survived was 28.1 +/- 12.4 (Group 1), 71.6 +/- 16.2 (Group 2), and 77.5 +/- 12.7 (Group 3) (P < 0.001, Group 1-3, 2-3). No differences were observed between Groups 2 and 3. CONCLUSIONS: Locally administered VEGF protein or plasmid DNA expressing VEGF enhanced survival of fasciocutaneous flaps.

Avoiding the Unfavorable Outcome with Wise Pattern Breast Reduction.

Wise pattern breast reduction remains the most popular method of performing moderate- to large-sized breast reductions in the United States. Shape distortion after breast reduction can be a result of design flaw, execution of technique, or the result of postoperative complications. This article focuses primarily on optimal design and intraoperative techniques for prevention of shape distortion. By carefully considering the design of the skin resection pattern, choosing and designing an appropriate pedicle, preventing skin necrosis, and managing scars, shape distortion after Wise pattern breast reduction can be minimized.

The lower trapezius musculocutaneous flap revisited: versatile coverage for complicated wounds to the posterior cervical and occipital regions based on the deep branch of the transverse cervical artery.

The clinical role of the lower trapezius musculocutaneous flap varies within the literature. Many describe its use in the reconstruction of the lateral neck and facial regions, but very few refer to its use in the posterior cervical and occipital regions. Different vascular pedicles have also been described and effectively used. A retrospective analysis was conducted, reviewing the authors' experience with 13 patients who suffered complex open wounds to the posterior cervical and occipital regions that were treated with a lower trapezius muscle or musculocutaneous flap. All flaps were based on the deep branch of the transverse cervical artery. This pedicle was used to support a relatively large skin segment over the distal portion of the lower trapezius muscle, a margin that, in the authors' experience, extends at least 1 cm beyond the muscular margin. Postoperatively, patients were evaluated based on complications, residual shoulder function, and aesthetic outcome. In addition to the clinical study, cadaveric dissection of the trapezius muscle was conducted on 22 specimens, and the vascular anatomy was confirmed by direct visualization. The authors' experience indicates that the lower trapezius musculocutaneous flap, when based on the deep branch of the transverse cervical artery, provides a reliable alternative for the reconstruction of complicated wounds in the posterior cervical and occipital regions, with the added capability of providing richly vascularized tissue to compromised wounds as far cephalad as the vertex of the skull.

Correlation of breast cancer axillary lymph node metastases with stem cell mutations.

IMPORTANCE: Mutations in oncogenes AKT1, HRAS, and PIK3CA in breast cancers result in abnormal PI3K/Akt signaling and tumor proliferation. They occur in ductal carcinoma in situ, in breast cancers, and in breast cancer stem and progenitor cells (BCSCs). OBJECTIVES: To determine if variability in clinical presentation at diagnosis correlates with PI3K/Akt mutations in BCSCs and provides an early prognostic indicator of increased progression and metastatic potential. DESIGN, SETTING, AND PARTICIPANTS: Malignant (BCSCs) and benign stem cells were collected from fresh surgical specimens via cell sorting and tested for oncogene mutations in a university hospital surgical oncology research laboratory from 30 invasive ductal breast cancers (stages IA through IIIB). MAIN OUTCOMES AND MEASURES: Presence of AKT1, HRAS, and PIK3CA mutations in BCSCs and their correlation with tumor mutations, pathologic tumor stage, tumor histologic grade, tumor hormone receptor status, lymph node metastases, and patient age and condition at the last follow-up contact. RESULTS: Ten tumors had mutations in their BCSCs. In total, 9 tumors with BCSC mutations and 4 tumors with BCSCs without mutations had associated tumor present in the lymph nodes (P = .001). CONCLUSIONS AND RELEVANCE: Tumors in which BCSCs have defects in PI3K/Akt signaling are significantly more likely to manifest nodal metastases. These oncogenic defects may be missed by gross molecular testing of the tumor and are markers of more aggressive breast cancer. Molecular profiling of BCSCs may identify patients who would likely benefit from PI3K/Akt inhibitors, which are being tested in clinical trials.

The use of microplates for internal fixation of mandibular fractures.

BACKGROUND: The use of microplates in mandible fractures is not widely accepted, although microplate systems are commonly used for treatment of maxillofacial fractures. This study evaluated the use of microplates for internal fixation of mandibular fractures with no comminution or bony defects. METHODS: Thirty-five patients with mandibular fractures (26 double and nine single) were treated. Of the 61 fractures, 54 were stabilized using 0.55-mm-thick microplates and 1.2-mm monocortical microscrews. The fractures were exposed through either an intraoral or a percutaneous approach. In general, two-point fixation with two microplates or one microplate and wires was performed. Interdental wiring was added for symphyseal or body fractures to confer further stability onto the dental arch. No intermaxillary fixation was used. RESULTS: During a follow-up period ranging from 3 to 29 months, all fractures showed complete bone healing. There were eight complications in seven patients with a double fracture, including mild malocclusion (n = 3), paresthesia (n = 3), asymptomatic delayed union (n = 1), and asymptomatic plate fracture (n = 1). No further orthodontic or surgical treatment was performed as a result of these complications. No other complications requiring further treatment occurred. There were three residual complications of mild malocclusion, paresthesia, and asymptomatic plate fracture at final follow-up. CONCLUSIONS: These results indicate that two-point fixation with microplates is appropriate for the internal fixation of simple, isolated mandibular fractures. Its advantages include a high adaptability to the fracture site, occlusal self-adjustment, a minimal mass effect, and a relatively strong holding power of two-point fixation.

Integrated plastic surgery residency applicant survey: characteristics of successful applicants and feedback about the interview process.

BACKGROUND: Integrated plastic surgery residency training is growing in popularity, bringing new challenges to program directors and applicants. The purpose of this study was to identify characteristics of successful applicants and to obtain feedback from applicants to improve the integrated plastic surgery residency training application and interview process. METHODS: An anonymous survey assessing applicant academic qualifications, number of interviews offered and attended, and opinions about the application and interview process was distributed electronically to the 2006 integrated plastic surgery residency training applicant class. The number of interviews offered was used as an indicator of potential applicant success. RESULTS: A 38 percent survey participation rate (139 of 367) was achieved. United States Medical Licensing Examination Step 1 score correlated with number of interview invitations (p < or = 0.001). Successful Alpha Omega Alpha designation (p < or = 0.001), high class rank (p = 0.034), presence of a plastic surgery residency program at the participant's school (p = 0.026), and authorship of one or more publications (p < or = 0.001) were associated with receiving greater number of interview invitations. Geographic location was an important consideration for applicants when applying to and ranking programs. Applicants desired interviews on weekdays and geographic coordination of interviews. CONCLUSIONS: Integrated plastic surgery residency training is highly competitive, with the number of interview invitations correlating with academic performance and, to a lesser extent, research. Applicant feedback from this survey can be used to improve the application and interview process.

Analysis of complications from abdominoplasty: a review of 206 cases at a university hospital.

The number of abdominoplasties performed in the United States has been steadily increasing over the past decade. A large proportion of these patients are bariatric patients who remain obese despite prior weight-reduction surgery. This study was done to review the experience of patients undergoing abdominoplasty at a university hospital. A retrospective chart review of 206 consecutive patients was performed. The overall complication rate was 37.4%. Major complications [hematoma requiring surgical intervention, seroma requiring aspiration or surgical drainage, cellulitis or abscess requiring hospitalization and intravenous (IV) antibiotics, deep vein thrombosis (DVT), and pulmonary embolism (PE)] occurred in 16% of patients. The rate of minor complications (hematoma or seroma requiring no intervention, epidermolysis, small-wound dehiscence, neuropathic pain, and minor cellulitis) was 26.7%. Obese patients had a significantly increased risk of developing major complications as compared with nonobese patients (53.4% versus 28.8%, P = 0.001). An in-depth analysis of all complications and risk factors was done.
