Volumetric Analysis of a Novel Chimeric Gracilis and Profunda Artery Perforator Flap.

BACKGROUND: The presence of a chimeric gracilis and profunda artery perforator (PAP) flap with a common arterial pedicle has been demonstrated on computed tomography angiography in up to 59% of patients and confirmed in a cadaveric model. Already utilized for head and neck reconstruction by Heredero et al, this novel flap could provide more volume than either flap alone which is advantageous, particularly in patients with sizable defects. The purpose of this study was to determine the average tissue volume that can be utilized from this chimeric flap. METHODS: CT Angiogram imaging studies exhibiting chimeric flap anatomy were reviewed over a 7-year period at a single institution utilizing Visage Version 7.1, a radiology picture archiving and communication system. This software was used to trace the flap pedicles and to capture estimated soft tissue volumes of each respective flap. RESULTS: A total of 31 patients, consisting of 52 lower extremity gracilis and PAP chimeric flaps, underwent tissue volume analysis. The average total volume of soft tissue supplied by the gracilis flap was found to be 70.21 cm3 (standard deviation [SD] = 26.99). The average volume of the PAP flap was 31.73 cm3 (SD = 26.12). The average total volume captured by the chimeric gracilis and PAP flap was 101.94 cm3 (SD = 62.40). CONCLUSION: The potential soft tissue volume that can be harvested from a chimeric gracilis and PAP flap is significantly greater than solitary gracilis or PAP flaps. This chimeric flap may serve as a viable and advantageous reconstructive option for patients requiring large volume soft tissue coverage, particularly if other sizable options are not available.

The Impact of Same-Day Discharge and Enhanced Recovery on Patient Quality of Life After Mastectomy with Implant Reconstruction.

BACKGROUND: This study aimed to evaluate how enhanced recovery (ER) protocols and same-day discharge (SDD) influences patients' postoperative quality of life (QOL). METHODS: Patients who underwent mastectomy with implant-based breast reconstruction from 2008 to 2020 were identified in a prospective database. The study assessed QOL with BREAST-Q and Was It Worth It? (WIWI) questionnaires. Responses were compared between the ER and pre-ER groups and between the SDD and hospital stay (HS) groups using one-way analysis of variance (ANOVA) and chi-square tests. RESULTS: The inclusion criteria were met by 568 patients, with a 43% response rate, and 217 patients were included for analysis. Chest physical well-being was lower for the ER cohort, but postoperative breast satisfaction was higher. Psychosocial status, sexual well-being, and satisfaction with information given did not differ significantly between the ER group and the pre-ER or SDD group. In the compared groups, QOL did not differ significantly. CONCLUSIONS: Enhanced recovery with SDD after mastectomy using implant-based reconstruction did not have an adverse impact on patient postoperative QOL.

Operating in an Opioid Crisis: A Temporal Analysis of Pain Medication Prescribing Practices in Plastic Surgery.

BACKGROUND: In response to the opioid epidemic, the United States declared a public health emergency in 2017. We evaluated pain medication prescribing practices among plastic and reconstructive surgeons, assessing pain medication prescription rates and opioid-related mortality both nationally and regionally within the United States. METHODS: A retrospective analysis of Medicare Part D prescriber data among plastic surgeons from 2013 through 2017 was conducted. Pain medications were categorized as opioid and nonopioid medications. Trends in surgeon prescribing habits were evaluated using the Cochrane-Armitage trend test. RESULTS: A total of 708,817 pain medication claims were identified: 612,123 claims (86%) were for opioid pain medications and 96,694 claims (14%) were for nonopioid pain medications. Total pain medication claims decreased from 44% of all medications in 2013 to 37% in 2017 (P < 0.001). Opioid medications decreased from 37% of total medication claims to 32% (P < 0.001). The overall opioid prescription rate fell from 1.53 claims per beneficiary in 2013 to 1.32 in 2017 (P < 0.001). Nonopioid pain medications decreased from 7% in 2013 to 6% in 2017 (P < 0.001); nonsteroidal anti-inflammatory drug claims increased by 44%. The prescription rate of nonopioid medications decreased from 2.40 claims per beneficiary in 2013 to 2.32 in 2017 (P < 0.001). An overall increase in opioid-related mortality was observed. Trends in pain medication prescriptions varied significantly among US regions and divisions. CONCLUSIONS: Plastic surgeons are prescribing less opioids and relying more on nonopioid pain medications. Increased adoption of multimodal pain treatment approaches among surgeons is a likely explanation for this trend in face of the current opioid crisis.

Unplanned implant removal in locally advanced breast cancer.

Study conducted to determine frequency and timing of unplanned breast implant removal after mastectomy, reconstruction, and postmastectomy radiation (PMRT). From 2010-2017, 52 patients underwent mastectomy, reconstruction, and PMRT. With median follow-up of 3.1 years, 23 patients (44%) experienced implant removal. Implant removal occurred in 9 (17%) patients before starting PMRT and 14 (27%) patients after starting PMRT. Implant removal rates were similar for hypofractionated PMRT compared with standard fractionation and for proton compared with photon PMRT. Implant removal is common for women undergoing mastectomy and reconstruction followed by PMRT. The risk is clinically significant even before starting radiation.

Same-day Discharge Is Safe and Effective After Implant-Based Breast Reconstruction.

BACKGROUND: Same-day discharge after mastectomy is a recently described treatment approach. Limited data exist investigating whether same-day discharge can be successfully implemented in patients undergoing mastectomy with immediate implant-based breast reconstruction (IBR). METHODS: Patients having mastectomy with IBR from 2013 to 2019 were reviewed. Enhanced recovery with same-day discharge was implemented in 2017. Patient characteristics, oncologic treatments, surgical techniques, and 90-day postoperative complications and reoperations were analyzed comparing enhanced recovery patients with historical controls. RESULTS: A total of 363 patients underwent nipple-sparing (214, 59%) or skin-sparing (149, 41%) mastectomy with 1-stage (270, 74%) or tissue expander (93, 26%) IBR. Enhanced recovery was used for 151 patients, with 79 of these patients (52%) discharged same-day. Overall, enhanced recovery patients experienced a significantly lower rate of 90-day complications (21% vs 41%, P < 0.001), including hematoma (3% vs 11%, P = 0.002), mastectomy flap necrosis (7% vs 15%, P = 0.02), seroma (1% vs 9%, P < 0.001), and wound breakdown (3% vs 9%, P = 0.05). Postoperative complication rates did not significantly differ among enhanced recovery patients discharged same day. Postoperative admissions significantly decreased after enhanced recovery implementation (100% to 48%, P < 0.001), and admitted enhanced recovery patients experienced a lower length of stay (1.2 vs 1.8, P < 0.001). Enhanced recovery patients experienced a lower incidence of ≥1 unplanned reoperation (22% vs 33%, P = 0.01); overall average unplanned and total reoperations did not significantly differ between groups. CONCLUSIONS: In conjunction with enhanced recovery practices, same-day discharge after mastectomy with IBR is a safe and feasible treatment approach.

Does Prior Breast Augmentation Affect Outcomes After Mastectomy With Reconstruction? An Analysis of Postoperative Complications and Reoperations.

BACKGROUND: The purpose of this study is to evaluate how prior breast augmentation impacts rates of complications and risk for reoperation after mastectomy with concurrent breast reconstruction. METHODS: Patients undergoing nipple-sparing, skin-sparing, or simple mastectomy with implant-based reconstruction from 2008 to 2018 were identified in a prospective database. Postoperative complications and reoperations were then analyzed comparing patients with prior augmentation to patients without history of previous breast surgery. RESULTS: A total of 468 patients were identified with a median follow-up of 4 years. Of these, 72 had prior augmentation mammoplasty. These patients underwent nipple-sparing (52, 72%), skin-sparing (15, 21%), or simple (5, 7%) mastectomy with immediate direct-to-implant (46, 61%) or tissue expander (26, 35%) reconstruction. On univariate analysis, this cohort had a lower body mass index (23.3 vs 25.3, P = 0.003), a higher rate of nipple-sparing mastectomy (72% vs 54%, P = 0.01), and a higher prevalence of stage I disease (44% vs 33%, P = 0.04). Differences in age, comorbidities, reconstructive techniques, tumor size, and neoadjuvant/adjuvant therapies were not significant. Overall complication rate between patients with or without prior augmentation did not significantly differ (51% vs 50%, P = 0.83); no significant differences in rates of surgical site infection, hematoma, mastectomy skin flap/wound necrosis, nipple complications, implant loss, or capsular contracture were found. Analysis of reoperations between patients with and without prior augmentation revealed no significant differences in average number of subsequent planned, unplanned, or total reoperations. On multivariate analysis, prior breast augmentation was found to be associated with significantly increased risk for undergoing ≥1 unplanned reoperation (odds ratio, 2.28; 95% confidence interval, 1.28-4.05, P = 0.005). CONCLUSIONS: Prior augmentation mammoplasty does not significantly affect rates of postoperative complications after mastectomy with concurrent reconstruction. Although prior augmentation does not affect number of subsequent reoperations on average, it does increase the risk of experiencing 1 or more unplanned reoperation after mastectomy with reconstruction.

3D Nipple-Areolar Tattoo: It's Technique, Outcomes, and Utilization.

BACKGROUND: Three-dimensional (3D) nipple-areolar tattoo is a novel approach to nipple-areolar complex reconstruction for which little data exist. Our aim was to evaluate 3D nipple-areolar tattoo outcomes and investigate if patient factors, payer status, surgeries, or therapies affect tattoo utilization. METHODS: Patients pursuing skin-sparing (SSM) or attempted nipple-sparing mastectomy (NSM) with breast reconstruction from 2008 to 2019 were reviewed. Outcomes included frequency of 3D tattoo, post-procedure complications (infections, or other local adverse sequelae), and rates, indications, and timing of revisions. Patient factors, payer status, surgeries, and adjuvant therapies underwent univariate analysis comparing rates of 3D tattoo and revisions. RESULTS: A total of 191 patients were identified; median follow-up was 4 years. The majority of patients were white (165, 86%), married (146, 76%), and post-menopausal (97, 51%), with private insurance (156, 81%). Surgeries included SSM (172, 90%) or attempted NSM (19, 10%) with implant (154, 81%) or autologous reconstruction (37, 19%). Sixty-two patients (32%) underwent 3D nipple-areolar tattooing. No post-procedure complications occurred. After tattooing, 20 patients (32%) pursued revisions, the majority due to color fading (12, 60%). Average time from tattoo to completion of revisions was 5.6 months. Patients undergoing autologous reconstruction had a higher rate of 3D tattooing (p < 0.001). Adjuvant radiation led to a higher rate of revisions (p = 0.02). Patient factors, payer status, index mastectomy, and chemotherapy did not significantly affect rates of 3D tattooing or revisions. CONCLUSIONS: 3D nipple-areolar tattoo utilization is likely unaffected by age, marriage, menopause, or payer status. Radiotherapy and color fading can lead to more revisions.

The Chimeric Gracilis and Profunda Artery Perforator Flap: Characterizing This Novel Flap Configuration with Angiography and a Cadaveric Model.

BACKGROUND: A chimerically configured gracilis and profunda artery perforator (PAP) flap is highly prevalent based on recent computed tomography (CT)-imaging data. The purpose of this study is to further characterize the vascular anatomy of this novel flap configuration and determine the feasibility of flap dissection. METHODS: To characterize flap arterial anatomy, lower extremity CT angiograms performed from 2011 to 2018 were retrospectively reviewed. To characterize venous anatomy and determine the feasibility of flap harvest, the lower extremities of cadavers were evaluated. RESULTS: A total of 974 lower extremity CT angiograms and 32 cadavers were included for the assessment. Of the 974 CT angiograms, majority (966, 99%) were bilateral studies, yielding a total of 1,940 lower extremities (right-lower-extremity = 970 and left-lower-extremity = 970) for radiographic evaluation. On CT angiography, a chimerically configured gracilis and PAP flap was found in 51% of patients (n = 494/974). By laterality, chimeric anatomy was present in 26% of right lower extremities (n = 254/970) and 25% of left lower extremities (n = 240/970); bilateral chimeric anatomy was found in 12% (n = 112/966) of patients. Average length of the common arterial pedicle feeding both gracilis and PAP flap perforasomes was 31.1 ± 16.5 mm (range = 2.0-95.0 mm) with an average diameter of 2.8 ± 0.7 mm (range = 1.3-8.8 mm).A total of 15 cadavers exhibited chimeric anatomy with intact, conjoined arteries and veins allowing for anatomical tracing from the profunda femoris to the distal branches within the tissues of the medial thigh. Dissection and isolation of the common pedicle and distal vessels was feasible with minimal disruption of adjacent tissues. Chimeric flap venous anatomy was favorable, with vena commitante adjacent to the common pedicle in all specimens. CONCLUSION: Dissection of a chimeric medial thigh flap consisting of both gracilis and PAP flap tissues is feasible in a cadaveric model. The vascular anatomy of this potential flap appears suitable for future utilization in a clinical setting.

Aesthetic Surgery Research Funding: Where Does It Come From and to Whom Does It Go?

BACKGROUND: Recent data show that aesthetic surgery research is lagging compared with reconstructive surgery: research funding and institutional disparities within aesthetic surgery are potential factors in this trend. OBJECTIVES: The authors sought to determine if disparities exist in aesthetic surgery research based on funding sources or practice settings. METHODS: The authors reviewed Aesthetic Surgery Journal articles from 2009 to 2019. Chi-square, t test, bivariate, and multivariate regression analyses were employed to evaluate research trends. RESULTS: A total of 2262 publications were identified, with 318 funded articles meeting inclusion criteria. The majority of studies (294, 92%) received external funding, with 281 (88%) being supported solely by external funds. Externally funded studies were financed by private industry (194, 66%), foundations/societies (53, 18%), government grants (23, 8%), or a combination of agencies (24, 8%). The majority of funded studies were at academic institutions (266, 84%), followed by private practice (46, 14%) and private industry (6, 2%). Analysis of annual publications revealed a rising percentage of academic-based research, which correlated with decreasing research from private practice (r = -0.95, r2 = 0.89, P < 0.001). Compared with academic institutions, private practice relied more heavily on industry funding (55% vs 87%, respectively, P = 0.001), exhibiting lower rates of foundational/societal (20% vs 2%), governmental (9% vs 0%), combined (8% vs 7%), and internal department funding (8% vs 4%). Article citations and level of evidence were unaffected by funding source, agency, or practice setting. CONCLUSIONS: Lack of diversity in research funding among private practice surgeons may explain the reported discrepancies that currently exist between aesthetic and reconstructive surgery research.

Robotic Harvest of a Rectus Abdominis Muscle Flap After Abdominoperineal Resection.

INTRODUCTION: As multidisciplinary treatment modalities for rectal cancer continue to evolve, neoadjuvant chemoradiation then surgical resection is a common approach. Robotic-assisted abdominoperineal resection is becoming more prevalent in part because of better visualization and instrument mobility within the pelvis. After abdominoperineal resection, postoperative perineal wound complications remain a significant risk. Pelvic reconstruction lowers this risk, and a pedicled rectus abdominis muscle flap is frequently used to achieve this. Traditional flap harvest requires laparotomy, resulting in violation of both rectus sheaths and a large midline scar. Robotic harvest of the rectus abdominis muscle for pelvic reconstruction after abdominoperineal resection is a novel approach with foreseeable benefits. TECHNIQUE: After completion of abdominoperineal resection, 2 additional trocars are inserted in the lateral abdomen, and the robot is reoriented toward the posterior abdominal wall. The peritoneum and posterior rectus sheath are incised, and dissection is carried superiorly and inferiorly in a sagittal plane to reveal the rectus abdominis muscle. The muscle body is separated from the anterior rectus sheath. Once the inferior epigastric artery is identified, the superior pole of the muscle is transected. Continued lateral dissection ensures flap mobility for placement within the pelvis. After obtaining proper reach, the robot is undocked, and the flap is sutured in place through the perineal defect. RESULTS: After trocar placement and robot repositioning, both the colorectal and plastic surgeons trade places at the console. Robotic flap harvest precludes the need for laparotomy. The anterior rectus sheath remains unviolated and the patient avoids an additional midline scar. The aforementioned benefits of robot-assisted abdominoperineal resection, namely increased visualization and maneuverability, were also found applicable when robotically harvesting this flap. CONCLUSIONS: This technique exemplifies an additional minimally invasive technique for patients pursuing abdominoperineal resection. With knowledge of this novel approach, surgeons can better tailor their operations to benefit the patient.

Gauging the efficacy of neoadjuvant endocrine therapy in breast cancer patients with known axillary disease.

BACKGROUND AND OBJECTIVES: Neoadjuvant endocrine therapy (NET) for ER+ breast cancer can downstage primary tumors. We evaluated NET efficacy in node-positive patients. METHODS: Node-positive patients undergoing NET for ER+ breast cancer from 2012 to 2019 were reviewed. Primary endpoints included rates of axillary lymphadenectomy (ALND), pathologic complete response (pCR), and final nodal staging. RESULTS: Thirty-nine patients were included. Before NET, all were clinically node-positive (cN1 = 36, 94%; cN2 = 2, 5%; cN3 = 1, 3%; Stage II = 23, 59%, Stage III = 16, 41%). After NET, nine (23%) had clinically persistent axillary disease necessitating ALND. The remaining 30 (77%) underwent sentinel lymph node biopsy (SLNB). Of these, 25 (83%) were SLNB+ on frozen section, undergoing immediate ALND. Five patients were negative on frozen section: one had a confirmed axillary pCR, and four had residual nodal disease on permanent pathology. One underwent delayed ALND, and for the remaining three patients, decision was made to forgo ALND. Final overall axillary staging was: N0 (pCR) = 1, 3%, pN1mic = 1, 3%, pN1 = 20, 51%, pN2 = 12, 30%, pN3 = 5, 13%; Stage II = 16, 41%, Stage III = 23, 59%. CONCLUSIONS: While NET is reported to downstage primary tumors, downstaging of the axilla was unsuccessful in the majority of patients.

New Perspectives in Surgical Marking Since the Advent of Infrared Laser Angiography.

INTRODUCTION: This study investigates the utility of common surgical dyes under direct visualization and infrared laser angiography. METHODS: Pigments affecting light within the visual (λ = 400-700 nm) and infrared (λ = 700-1000 nm) spectra were placed on subjects spanning the Fitzpatrick scale. Photometric properties of these pigments were assessed under direct visualization and infrared laser angiography. RESULTS: Among patients of various Fitzpatrick classifications, black ink pigment and pigment within the violet spectrum (λ = 380-450 nm) were most distinguishable under direct visualization. Colored inks, gentian violet and methylene blue dyes, were not visualized under infrared laser angiography. Black permanent ink appeared under both direct visualization and infrared laser angiography. Indocyanine green suspended in ethyl alcohol and applied to skin as a marking pen appeared clear under direct visualization and was detectable under infrared laser angiography. CONCLUSIONS: Black permanent marking ink allows visualization of surgical markings under infrared laser angiography, whereas gentian violet and methylene blue did not interfere with infrared visualization. Indocyanine green suspended in ethyl alcohol is a contemporary marking pen that may be used to outline anatomical surface landmarks under infrared laser angiography.

A Newly Described, Highly Prevalent Arterial Pedicle Perfuses Both Gracilis and Profunda Artery Perforator Flap Tissues: An Angiographic Study of the Medial Thigh.

BACKGROUND: Novel secondary flap options are paramount for patients who are not candidates for common reconstructive methods. The purpose of this study is to identify the prevalence of single arterial pedicle supplying both the gracilis muscle and medial thigh tissue carried in a profunda artery perforator (PAP) flap. Such a pedicle could allow the creation of a chimeric gracilis and PAP flap with a single-arterial anastomosis. METHODS: We conducted a retrospective review of 157 lower extremity computed tomography (CT) angiograms to assess the vasculature of the thigh soft tissues. Imaging evaluation was supervised by a board-certified musculoskeletal radiologist. RESULTS: Prevalence of a single-arterial pedicle to a gracilis and PAP flap in each patient was 59% (31% within the right leg and 28% in the left leg). Furthermore, 16% of patients had a common arterial pedicle in both lower extremities. CONCLUSION: Existence of a single-arterial pedicle to both the gracilis muscle and PAP flap tissues is frequently present in most patients in at least one lower extremity. This chimeric flap configuration could serve as a reconstructive avenue for patients, particularly those who have exhausted other more common flap options. Screening angiography is warranted in patients looking for this anatomic variation to establish its presence.

Can Montgomery tubercles impact aesthetic 3D nipple-areolar complex tattooing? An anatomical, quantitative analysis of breast cancer patients.

PURPOSE: We aimed to establish a relationship between the amount of Montgomery tubercles (MTs) per nipple-areolar complex (NAC) given patient characteristics such as age, BMI, menopausal status, race/ethnicity, and NAC size to better inform current 3D NAC tattooing practices. METHODS: Preoperative photographs of patients pursuing breast reconstruction after mastectomy in 2010 through 2018 were reviewed. The number of MTs on each native NAC was quantified. The impact of patient factors on the quantity of MTs was evaluated via Pearson correlation and bivariate analyses. RESULTS: Two hundred and eleven patients (399 breasts) were reviewed. On average, patients had 5.0 ± 5.2 MTs (range, 0-25 MTs). Number of MTs did not correlate with patient age, BMI, or NAC size. Premenopausal females were more likely than postmenopausal females to have a greater number of MTs per breast (p-value = 0.0183). CONCLUSIONS: Postmastectomy patients desiring a more "youthful" NAC may consider additional MTs when pursuing 3D NAC tattooing.

Postoperative Complication Impact on Quality of Life after Postmastectomy Breast Reconstruction.

BACKGROUND: Although the overall psychosocial benefits and body image gains of postmastectomy breast reconstruction are well-established, there is limited information on how postoperative complications affect patient quality of life (QOL). STUDY DESIGN: A single-institution cross-sectional survey analysis was performed on patients who underwent postmastectomy breast reconstruction between 2008 and 2020. QOL was assessed using the BREAST-Q and the Was It Worth It questionnaires. The results were compared among patients who had major complications, minor complications, and no complications. Responses were compared using 1-way ANOVA and chi-square tests as appropriate. RESULTS: A total of 568 patients met inclusion criteria, and 244 patients responded (43% response rate). Most patients did not have any complications (n = 128; 52%), 41 had minor complications (17%), and 75 had major complications (31%). There were no differences in any of the BREAST-Q well-being metrics based on degree of complication. Across all 3 groups, patients reported that surgery was worthwhile (n = 212; 88%), they would choose reconstruction again (n = 203; 85%), and they would recommend it to a friend (n = 196; 82%). Overall, 77% reported that their overall experience either met or exceeded expectations, and 88% of patients had unchanged or improved overall QOL. CONCLUSIONS: Our study demonstrates that QOL and well-being are not negatively impacted by postoperative complications. Although patients who had no complications had an overall more positive experience, nearly two-thirds of all patients, no matter the degree of complication, stated that their overall experience either met or exceeded their expectations.

A 20-Year Analysis of Medicare Reimbursement for Abdominal Wall Reconstruction (2000 to 2020).

BACKGROUND: The purpose of this study was to evaluate monetary trends in Medicare reimbursement rates for 30 abdominal wall reconstruction surgical procedures over a 20-year period (2000 to 2020). METHODS: The Physician Fee Schedule Look-Up Tool from the Centers for Medicare and Medicaid Services was used for each of the 30 included current CPT codes, and reimbursement data were extracted. Monetary data were adjusted for inflation to 2020 U.S. dollars using changes to the United States consumer price index. The R 2 values for the average annual percentage change and the average total percentage change in reimbursement were calculated based on these adjusted trends for all included procedures. RESULTS: After adjusting for inflation, the average reimbursement for all procedures decreased by 17.1% from 2000 to 2020. The greatest mean decrease was observed for CPT code 49568 (the implantation of mesh or other prosthesis for open incisional or ventral hernia repair or mesh for closure of débridement for necrotizing soft-tissue infection, -34.4%). The only procedure with an increased adjusted reimbursement rate throughout the study period was CPT code 20680 (+3.9%). From 2000 to 2020, the adjusted reimbursement rate for all included procedures decreased by an average of 0.85% each year, with an average R 2 value of 0.78, indicating a stable decline throughout the study period. CONCLUSIONS: Reimbursement rates are declining when adjusted for inflation. Increased awareness of these trends is helpful to maintain access to optimal abdominal reconstruction care in the United States.
