ABSTRACT
Necrosis of the nipple-areolar complex (NAC) or surrounding skin has been reported in 6%-30% of nipple-sparing mastectomy (NSM) patients, with higher rates associated with larger breasts, previous breast surgery, previous radiation, and active smoking. The nipple delay (ND) procedure is known to improve viability of the NAC in NSM patients with high-risk factors. Methods: A single-institution retrospective review was done of patients who underwent ND and NSM or NSM alone from 2012 to 2022. Patient demographics, risk factors, and outcomes were compared. Results: Forty-two breasts received ND-NSM and 302 breasts received NSM alone. The ND-NSM group had significantly more high-risk factors, including elevated BMI (26.3 versus 22.9; P < 0.001), elevated prior breast surgery (50% versus 25%; P < 0.001), and greater mastectomy specimen weight (646.6 versus 303.2 g; P < 0.001). ND-NSM was more likely to have undergone preparatory mammoplasty before NSM (27% versus 1%; P < 0.001). There was no delay in NSM treatment from decision to pursue NSM (P = 0.483) or difference in skin necrosis (P = 0.256), NAC necrosis (P = 0.510), hematoma (P = 0.094), seroma (P = 0.137), or infection (P = 0.437) between groups. ND-NSM and NSM patients differed in total NAC necrosis (0% versus 3%) and implant loss (0% vs 13%), but not significantly. Conclusions: We demonstrated no NAC necrosis and no significant delay of treatment in higher risk ND-NSM patients. ND may allow higher risk patients to undergo NSM with similar morbidity as lower risk patients.
ABSTRACT
SUMMARY: Women with inadequate myocutaneous or fasciocutaneous soft-tissue donor sites for breast reconstruction after mastectomy are mostly limited to implants. Alternative substitutes are needed for those who do not want-or in whom there are contraindications for-implant-based reconstruction. The authors report a novel technique using an omental fat-augmented free flap to create an autologous breast mound that has comparable shape and projection to a breast implant. Three patients with breast cancer who desired unilateral reconstruction were identified in the period 2019 to 2020. All had insufficient traditional autologous sites and were averse to the use of implants. A nipple-sparing mastectomy was performed, and the omentum was laparoscopically harvested and fat-grafted ex vivo and then encased in acellular dermal matrix for microvascular anastomoses. The body mass indexes of the three patients were 17.6, 25, and 28.3 kg/m2. Each individual's mastectomy specimens and corresponding omentum plus fat-grafting weights were 113.7/228, 271/293, and 270/360 g. No postoperative complications occurred. The reconstructed breast remains soft, with stable breast volume at 6 months and without evidence of fat necrosis. This novel use of fat grafting into an omental flap enveloped in acellular dermal matrix, the omental fat-augmented free flap, provides a viable and successful autologous alternative for patients who are not candidates for traditional autologous breast reconstruction options because of body habitus or personal preference.

INTRODUCTION: Breast reconstruction is most commonly performed using implant-based reconstruction. Patients with subpectoral implant placement with or without latissimus dorsi (LD) muscle coverage can experience muscle pain and animation deformity. Due to minimal literature describing the use of botulinum toxin (BTX-A) treatment for these side effects from implant-based reconstruction, we report our outcomes. METHODS: A retrospective chart review of breast reconstructive patients for a single surgeon was performed. Patients who underwent BTX-A injection for muscular pain, spasm, or animation deformity were identified and outcomes reviewed. They were also stratified based on radiation treatment and type of muscle flap used. RESULTS: Eleven patients were identified who had a submuscular pectoralis pocket and/or a pedicled latissimus dorsi flap. Nineteen breasts were treated. The average amount of time from the patient's last surgery to BTX-A injection was 11.2 months. 25-100 units were used per injection with an average of 60 units. Non-irradiated patients had signifycantly lower post-injection capsular contracture Baker grades and significantly lower amounts of BTX-A were injected. Patients who had both pectoralis major muscle and LD implant-reconstruction were significantly less likely to have improvement in pain/tightness. Most patients reported improvement or resolution of their pain and/or animation deformities. CONCLUSION: Implant-based reconstruction using the pectoralis major and/or LD muscles can be plagued with muscular pain, spasm, and animation deformities. The use of BTX-A is a diagnostic and therapeutic modality for these post-breast reconstruction patients with most patients having resolution of symptoms without the need for additional surgery.

PURPOSE: Cranial defects in children have been repaired with various materials ranging from autologous bone to synthetic materials. There is little published literature on the outcomes of titanium mesh cranioplasty (TMC) in calvarial reconstruction in the pediatric population. This study evaluates a pediatric cohort who underwent calvarial defect reconstruction with titanium mesh and assesses the efficacy and outcomes of TMC. METHODS: An Institutional Review Board approved retrospective review of patients ≤18 years of age who underwent cranioplasty from 1999 to 2014 at 2 centers was performed. The cohort undergoing TMC was studied. RESULTS: A total of 159 cranioplasties were performed. Autologous reconstruction included 84 bone flap replacements and 36 split calvarial bone graft reconstructions. Six patients underwent PEEK implant reconstruction. Titanium mesh cranioplasty was performed on 33 patients. Two patients underwent 2 separate cranioplasties. The median age of patients was 6 years (19 months to 18 years). The most common underlying etiologies were congenital syndromes/craniosynostosis (13 patients), and trauma (11). The majority of patients had prior cranial surgeries (85%). Various types of titanium mesh were used with sizes ranging from 2×3âcm to 19×20âcm, with some patients requiring distinct areas of defect reconstruction. Perioperative complications were noted in 2 patients that subsequently improved. Two patients had late soft tissue problems with complications of wound infections requiring resection of a portion of the mesh. Patients were followed an average of 4 years (range 13 days to 6.8 years), with 2 patients lost to follow-up. Overall, all patients with follow-up achieved a cranial contour with good symmetry to the unaffected side, as well as effective protection to the brain. CONCLUSIONS: Titanium mesh cranioplasty is an effective option for correcting pediatric cranial defects when autologous bone availability is limited and soft tissue coverage allows placement of an implant. The interim outcome for these patients is favorable with few complications and no evidence of growth restriction in the authors' series. Follow-up will be ongoing for these patients.

BACKGROUND: Women considering risk reduction surgery after a diagnosis of breast/ovarian cancer and/or inherited cancer gene mutation face difficult decisions. The safety of combined breast and gynecologic surgery has not been well studied; therefore, we evaluated the outcomes for patients who have undergone coordinated multispecialty surgery. METHODS: We conducted a retrospective review of patients undergoing simultaneous breast and gynecologic surgery for newly or previously diagnosed breast cancer and/or an inherited cancer gene mutation during the same anesthetic at a single institution from 1999 to 2013. RESULTS: Seventy-three patients with a mean age of 50 years (range 27-88) were identified. Most patients had newly diagnosed breast cancer or ductal carcinoma in situ (62 %) and 28 patients (38 %) had an identified BRCA mutation. Almost all gynecologic procedures were for risk reduction or benign gynecologic conditions (97 %). Mastectomy was performed in 39 patients (53 %), the majority of whom (79 %) underwent immediate reconstruction. The most common gynecologic procedure involved bilateral salpingo-oophorectomy, which was performed alone in 18 patients (25 %) and combined with hysterectomy in 40 patients (55 %). A total of 32 patients (44 %) developed postoperative complications, most of which were minor and did not require surgical intervention or hospitalization. Two of the 19 patients who underwent implant reconstruction (11 %; 3 % of the entire cohort) had major infectious complications requiring explantation. CONCLUSION: Combined breast and gynecologic procedures for a breast cancer diagnosis and/or risk reduction in patients can be accomplished with acceptable morbidity. Concurrent operations, including reconstruction, can be offered to patients without negatively impacting their outcome.

BACKGROUND: In children diagnosed with hepatoblastoma (HB), the lungs are the most common site of metastasis at both initial presentation and relapse. Previous studies have encouraged pulmonary metastasectomy to achieve a disease-free state after resection of the primary hepatic lesion. However, there is no consensus about how to manage recurrent pulmonary metastasis. PROCEDURE: A retrospective, multi-institutional review was performed from 2005 to 2014 to identify HB patients ≤18years of age who had disease recurrence associated with pulmonary metastases alone. RESULTS: Ten patients between the ages of 8 and 33months were identified. Pulmonary metastatic recurrence was detected by measuring alpha-fetoprotein (AFP) levels and/or with CT scans of the chest. All patients subsequently underwent pulmonary metastasectomy without post-operative complications. At last follow-up, 8 patients were alive and had normal AFP levels. The 8 survivors had a median follow-up from therapy completion of 18.5months. Two patients who presented with extrapulmonary recurrence subsequently died of treatment refractory disease. CONCLUSIONS: This review supports surgical resection as a safe and, in the context of multimodal therapy, efficacious approach to manage HB patients who present with isolated pulmonary relapse.

BACKGROUND: Focal nodular hyperplasia (FNH) is uncommonly diagnosed in pediatric patients and may be difficult to distinguish from a malignancy. We present a review of all children with a tissue diagnosis of FNH at our institution, describe the diagnostic modalities, and provide recommendations for diagnosis and follow-up based on our experience and review of the literature. METHODS: A retrospective review of children <18years of age diagnosed with FNH at a single institution was performed from 2000 to 2013. RESULTS: Twelve patients were identified with a tissue diagnosis of FNH. Two patients required surgical resection of their lesion owing to concern for malignancy. Ten patients were managed expectantly with imaging surveillance after biopsy confirmed a diagnosis of FNH. All patients who underwent MRI had very typical findings including hypointensity on T1 weighted sequences, hyperintensity on T2, and homogenous uptake of contrast on the arterial phase. On follow-up all patients had either a stable lesion or reduction in size. CONCLUSIONS: Focal nodular hyperplasia presents typically in children with liver disease, have undergone chemotherapy, and adolescent females. Young children, particularly <5years of age, without underlying liver disease or history of chemotherapy can pose a diagnostic dilemma. In this unique subgroup of children with FNH, MRI and/or needle biopsy should be adequate diagnostic modalities for these lesions.

BACKGROUND: Women present with pectus excavatum five times less frequently than men. Adult women may have additional, associated cosmetic factors, including hypoplastic or asymmetric breasts, or prior augmentation. The authors evaluated the impact of prior or concurrent cosmetic breast surgery in an adult female cohort undergoing repair of pectus excavatum deformity. METHODS: A retrospective review was performed of women (≥18 years old) who underwent pectus excavatum repair at a single institution from January of 2010 to September of 2013. RESULTS: Pectus excavatum repair was performed on 47 women with a median age of 35 years (range, 18 to 63 years). Mean pectus severity index was 6.2 (range, 3.1 to 16). All patients had physiologic symptoms as the primary purpose for seeking repair. Twenty patients (43 percent) presented with existing implants or the desire for implants at the time of repair. Fifteen patients (32 percent) had a history of implant placement including prior breast augmentation (n = 14) and/or pectus implant (n = 4). Concurrent augmentation (n = 5), breast implant exchange (n = 8), and/or removal of chest wall implants (n = 4) was performed during repair. Morbidity included one implant-related hematoma. Complications and hospital stay were not significantly different for patients undergoing primary repair alone versus those with prior or concurrent augmentation. CONCLUSIONS: Breast cosmesis was a concern in nearly half of adult women presenting for pectus excavatum repair. The authors' experience suggests neither prior nor concurrent breast augmentation increases the risk of complications in repair. The authors recommend that cosmetic breast surgery be performed concurrently with pectus excavatum repair. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

BACKGROUND: Vascular endothelial growth factor (VEGF), a well-characterized regulator of angiogenesis, has been mechanistically implicated in retinal neovascularization and in the pathogenesis of retinopathy of prematurity. However, the ontogeny of VEGF expression in the human fetal retina is not well known. Because retinal vasculature grows with gestational maturation, we hypothesized that VEGF expression also increases in the midgestation human fetal eye as a function of gestational age. METHODS: To identify changes in VEGF gene expression during normal human development, we measured VEGF mRNA by quantitative PCR and measured VEGF protein by enzyme-linked immunosorbent assay and western blots in 10-24 wk gestation fetal vitreous, retina, and serum. RESULTS: VEGF mRNA expression in the retina increased with gestational age. VEGF isoform A, particularly its VEGF121 splice variant, contributed to this positive correlation. Consistent with these findings, we detected increasing VEGF121 protein concentrations in vitreous humor from fetuses of 10-24 wk gestation, while VEGF concentrations decreased in fetal serum. CONCLUSION: VEGF121 mRNA and protein concentrations increase with increasing gestational age in the developing human retina. We speculate that VEGF plays an important role in normal retinal vascular development, and that preterm delivery affects production of this vascular growth factor.

Bariatric surgery is increasingly being performed in the medically complicated obese population as convincing data continue to mount, documenting the success of surgery not only in achieving meaningful weight loss but also in correcting obesity-related illnesses. Several surgical procedures with varying degrees of success and complications are currently being performed. This article discusses the short- and long-term gastrointestinal complications for the 4 most common bariatric surgical procedures: laparoscopic adjustable gastric banding, vertical sleeve gastrectomy, Roux-en-Y gastric bypass, and biliopancreatic diversion with duodenal switch.
