Outpatient Prescription Opioid Use following Discharge after Deep Inferior Epigastric Perforator Breast Reconstruction with and without an Educational Intervention.

BACKGROUND: There is limited evidence for appropriate postoperative opioid prescribing in autologous breast reconstruction. We sought to describe postoperative outpatient prescription opioid use following discharge after deep inferior epigastric perforator (DIEP) breast reconstruction with and without an educational video. METHODS: Patients undergoing DIEP reconstruction were given a 28-day postoperative pain and medication logbook from August 2022 to June 2023. Our practice implemented an educational video upon discharge on proper opioid consumption. Descriptive statistics on patient characteristics, intraoperative and postoperative opioid consumption, and outpatient prescription opioid use after discharge were compared between the two cohorts. RESULTS: A total of 53 logbooks were completed with 20 patients in the no video cohort and 33 in the video cohort. On average, the days to cessation of opiates was longer in the no video cohort (8.2 vs. 5.1 days, p = 0.003). The average number of oxycodone 5 mg equivalents consumed following discharge was 13.8 in the no video cohort and 7.8 in the video cohort, which was statistically significant (p = 0.01). Overall, the percentage of opioids prescribed that were consumed in the video cohort was 28.3% versus 67.1% in the no video cohort. CONCLUSION: For patients discharging home after DIEP reconstruction, we recommend a prescription for 12 oxycodone 5 mg tablets. With the use of an educational video regarding proper opioid consumption, we were able to reduce the total outpatient opioid use to 5 oxycodone 5 mg tablets following hospital discharge.

The Effect of Body Mass Index on Free Flap Breast Reconstruction.

BACKGROUND: Literature addressing the risks associated with increasing body mass index (BMI) for patients undergoing free flap breast reconstruction is limited. Often, an arbitrary BMI cutoff (i.e., BMI of 30 kg/m2) is used to determine candidacy for a free flap without substantial backing evidence. This study utilized a national multi-institutional database to analyze outcomes of free flap breast reconstruction and stratified complications by BMI class. METHODS: Using the 2010 to 2020 National Surgical Quality Improvement Program database, patients who underwent free flap breast reconstruction were identified. Patients were divided into six cohorts based on the World Health Organization BMI classes. Cohorts were compared by basic demographics and complications. A multivariate regression model was created to control for age, diabetes, bilateral reconstruction, American Society of Anesthesiologists class, and operative time. RESULTS: Surgical complications increased with each BMI class, with the highest rates occurring in class I, II, and III obesity, respectively. In a multivariable regression model, the risk for any complication was significant for class II and III obesity (odds ratio [OR]: 1.23, p < 0.004; OR: 1.45, p < 0.001, respectively). Diabetes, bilateral reconstruction, and operative time were independently associated with an increased risk of any complication (OR: 1.44, 1.14, 1.14, respectively, p < 0.001). CONCLUSION: This study suggests that the risks of postoperative complications following free flap breast reconstruction are highest for patients with a BMI greater than or equal to 35 kg/m2, having nearly 1.5 times higher likelihood of postoperative complications. Stratifying these risks by weight class can help guide preoperative counseling with patients and help physicians determine candidacy for free flap breast reconstruction.

Lasting Effects of Surgically Used Topical Vasodilators on DIEP Artery Vascular Function.

BACKGROUND: Surgeons routinely apply papaverine, lidocaine, or verapamil to produce acute vasodilation and prevent vasospasms during microvascular surgeries. There is evidence that topical vasodilators may induce postoperative endothelial and smooth muscle dysfunction, which would present after the acute vasodilatory effects of the topical drugs wear off. Therefore, the purpose of the current study was to evaluate the lasting effects of papaverine, lidocaine, and verapamil on human deep inferior epigastric perforator artery vasodilatory function after the acute effects of the topical drugs had worn off. METHODS: Deep inferior epigastric arterial samples were obtained from 12 patients during surgery. Each artery was dissected into four rings which where incubated for 1 minute in either physiological saline solution (control), papaverine (30 mg/mL), lidocaine (20 mg/mL), or verapamil (2.5 mg/mL), followed by a 2-hour washout. Endothelial-dependent and -independent vasorelaxation were then assessed by the isometric tension responses to acetylcholine or sodium nitroprusside, respectively. RESULTS: Peak acetylcholine-evoked vasorelaxation (mean ± standard deviation) was not different between control (62 ± 23%) and lidocaine (57 ± 18%, p = 0.881), but was reduced (all p < 0.002) in papaverine (22 ± 27%) and verapamil (22 ± 20%). Peak sodium nitroprusside-evoked vasorelaxation was not different (all p > 0.692) among control (132 ± 35%), lidocaine (121 ± 22%), and verapamil (127 ± 22%), but was less in papaverine (104 ± 41%; p = 0.045) than control. CONCLUSION: Surgically used doses of papaverine and verapamil, but not lidocaine, have lasting negative effects on arterial vasodilatory function despite the acute effects of the drugs having worn off. These findings, in conjunction with the spasmolytic properties of each drug, may help guide the selection of an optimal topical vasodilator for use during microvascular surgeries.

A Comparison of Postoperative Outcomes between Unilateral and Bilateral Palatoplasty: Analysis of 2015-2020 Pediatric NSQIP Data.

OBJECTIVE: We sought to identify differences in 30-day medical and surgical complications in unilateral versus bilateral palatoplasty. DESIGN: The NSQIP-P 2015-2020 database was queried to identify cleft palate repairs using CPT codes. Cases were stratified as unilateral (Veau III) and bilateral (Veau IV) using ICD-9 and -10 codes. SETTING: A nationally representative random sample. PATIENTS/PARTICIPANTS: A total of 3791 cases were identified with 2608 undergoing unilateral repair and 1183 undergoing bilateral repair. MAIN OUTCOMES/MEASURES: The postoperative outcomes of interest included surgical complications (surgical site infections, wound dehiscence), medical complications (pneumonia, urinary tract infection, seizure, cardiac arrest, bleeding/transfusions, systemic sepsis, unplanned intubation), readmission, and reoperation. RESULTS: The bilateral cohort was older (696 days versus 619 days, P < .001) and had longer operative times (157.3 min versus 144.5 min, P < .001). The unilateral cohort had more comorbidities including developmental delay, structural CNS abnormalities, need for nutritional support, and bleeding disorders. The bilateral cohort had statistically significant higher occurrences of wound dehiscence (2.1% versus. 1.2%, P = .03) and readmission (3.2% versus 1.7%, P = .01). On multivariate analysis, bilateral cleft repair (OR: 1.83, CI: 1.176-2.840, P = .007) and ASA class 4 (OR: 13.1, CI 2.288- 62.586, P = .002) were associated with greater odds of readmission. CONCLUSION: Patients who underwent bilateral cleft repair had a higher proportion of 30-day postoperative complications and a two-fold increased odds of readmission. While palatoplasty is generally regarded as a safe procedure in the pediatric population, identifying factors related to an increased risk of early postoperative complications can help surgical teams better manage high-risk individuals.

Analysis of Readmissions and Reoperations in Pediatric Microvascular Reconstruction.

BACKGROUND: Free tissue transfer is utilized as a reconstructive option for various anatomic defects. While it has long been performed in adults, reconstructive surgeons have used free tissue transfer to a lesser degree in children. As such, there are few analyses of factors associated with complications in free tissue transfer within this population. The aim of this study is to assess factors associated with readmission and reoperation in pediatric free flap patients utilizing the pediatric National Surgical Quality Improvement Program database. METHODS: Pediatric patients who underwent microvascular reconstruction between 2015 and 2020 were included. Patients were identified by five microvascular reconstruction Current Procedural Terminology codes and were then stratified by flap site (head and neck, extremities, trunk) and defect etiology (congenital, trauma, infection, neoplasm). Multivariate logistic regression was performed to identify factors associated with readmissions and reoperations. RESULTS: The study cohort consisted of 258 patients. The average age was 10.0 ± 4.7 years and the majority of patients were male (n = 149, 57.8%), were of white race (n = 164, 63.6%), and had a normal body mass index. Twenty-two patients (8.5%) experienced an unplanned readmission within 30 days of the initial operation, most commonly for wound disruption (31.8% of readmissions). The overall rate of unplanned reoperation within 30 days was 11.6% (n = 30) for all patients, with an average of 8.9 ± 7.5 days to reoperation. On multivariate regression analysis, each hour increase in operative time was associated with an increased odds of reoperation (odds ratio [OR]: 1.27; 95% confidence interval [CI]: 1.12, 1.45) and readmission (OR: 1.16; 95% CI: 1.02, 1.34). CONCLUSION: In pediatric patients undergoing free tissue transfer, higher readmission and reoperation risk was associated with longer operative duration. Overall, free tissue transfer is safe in the pediatric population with relatively low rates of readmission and reoperation.

A Comparison of Postoperative Outcomes Between Immediate, Delayed Immediate, and Delayed Autologous Free Flap Breast Reconstruction: Analysis of 2010-2020 NSQIP Data.

BACKGROUND: While many factors influence decisions related to the timing between mastectomy and flap-based breast reconstruction, there is limited literature comparing postoperative complications between immediate (IBR), delayed immediate (DIBR), and delayed (DBR) reconstruction modalities. Using the National Surgical Quality Improvement Program (NSQIP), we sought to compare postoperative complication rates of each timing modality. METHODS: The NSQIP 2010-2020 database was queried for patients who underwent free flap breast reconstruction. Cases were categorized to include mastectomy performed concurrently with a free flap reconstruction, removal of a tissue expander with free flap reconstruction, and free flap reconstruction alone which are defined as IBR, DIBR, and DBR, respectively. The frequency of postoperative outcomes including surgical site infection (SSI), wound dehiscence, intraoperative transfusion, deep venous thrombosis (DVT), and return to operating room (OR) was assessed. Overall complication rates, hospital length of stay (LOS), and operative time were analyzed. Multivariable regression analysis controlling for age, race, BMI, diabetes, hypertension, ASA class, and laterality was performed. RESULTS: A total of 7,907 cases that underwent IBR, DIBR (n = 976), and DBR reconstruction (n = 6,713) were identified. No statistical difference in occurrence of SSIs, wound dehiscence, or DVT was identified. DIBR (9%) and DBR (11.9%) were associated with less occurrences of reoperation than IBR (13.2%, p < 0.001). Univariate and multivariate regression analysis demonstrated that DIBR and DBR were associated with a lower odds of complications and shorter operation time versus IBR. No statistically significant differences between DIBR and DBR in surgical complications, LOS, and operative time were identified. CONCLUSION: Awareness of overall complication rates associated with each reconstructive timing modality can be used to help guide physicians when discussing reconstructive options. Our data suggests that DIBR and DBR are associated with less overall complications than IBR. Physicians should continue to consider patients' unique circumstances when deciding upon which timing modality is appropriate.

Elective surgery resource utilization.

PURPOSE: Cessation of elective surgery during COVID-19 was partly driven by concern for consumption of hospital resources required by critically ill patients. We aim to determine the extent of resource utilization by elective outpatient surgery to assist in ensuring future resource conservation decisions are data driven. METHODS: The study utilized a retrospective cohort gathered from the American College of Surgeons National Surgical Quality Improvement Program database. Participants were adult patients who underwent elective or non-elective surgery between 2017 and 2018. Outcomes included patient characteristics and post-operative outcomes for elective and non-elective surgeries. Post-operative outcomes were used as a surrogate for the consumption of hospital resources. RESULTS: A total of 1,558,938 (79.8%) elective and 393,339 (20.2%) non-elective surgeries were identified. Elective surgery patients were more likely to be outpatient status, have an ASA class < 3, and exhibited lower rates of prolonged ventilation, 30-day reoperation, and 30-day readmissions, and averaged 5 days less of inpatient stay. Elective outpatient surgery (vs. elective inpatient surgery) averaged shorter operative times and exhibited lower rates of readmissions (2.1% vs. 5.5%; p < 0.001), reoperations (1.1% vs. 2.8%; p < 0.001), prolonged ventilation (0.0% vs. 0.3%; p < 0.001), and 30-day mortality (0.1% vs. 0.5%; p < 0.001) and accounted for 30.2% of the overall relative value units ($339,815,038). CONCLUSION: We evaluated utilization of hospital resources by patients undergoing elective outpatient surgery by identifying surgeries performed in 2017-2018 then stratifying them by outpatient status. Elective outpatient surgeries consumed negligible amounts of hospital resources and should not be considered a threat to resources in the setting of high demand by critically ill COVID-19 patients.

Comparison of Human, Porcine, and Bovine Acellular Dermal Matrix in Prepectoral Breast Reconstruction: A Scoping Review.

OBJECTIVE: The aim of the study is to determine rates of overall complications and failure of prepectoral breast reconstruction between various types of acellular dermal matrices (ADMs). BACKGROUND: Implant-based breast reconstruction is the most common reconstructive technique after mastectomy in the United States. Traditionally, the reconstruction has been performed in the subpectoral plane; however, there has been an emerging interest in prepectoral reconstruction using ADM. Human (hADM), porcine (pADM), and bovine (bADM) ADMs are available for use, but little is known about the benefits and complication profiles of each for prepectoral breast reconstruction. METHODS: Studies examining complications after the use of ADM for prepectoral breast reconstruction were identified using MEDLINE, Embase, the Cochrane Library, LILACS, and the Web of Science from January 2010 to August 2021. Titles and abstracts of 1838 studies were screened, followed by full-text screening of 355 articles. Thirty-three studies were found to meet inclusion criteria. RESULTS: From the 33 studies, 6046 prepectoral reconstructions were examined. Implant loss was comparable across the different types of ADM (pADM, 4.0%; hADM, 4.0%; bADM, 3.7%). Bovine ADM had the highest rate of capsular contracture (6.1%), infection (9.0%), skin flap necrosis (8.3%), dehiscence (5.4%), and hematoma (6.1%) when compared with both hADM and pADM. Human ADM had the highest rate of postoperative seroma (5.3%), followed by pADM (4.6%) and bADM (4.5%). CONCLUSIONS: Among the prepectoral breast reconstruction studies using hADM, pADM, or bADM included in our analysis, complication profiles were similar. Bovine ADM had the highest proportion of breast complications in the following categories: capsular contracture, infection rate, skin flap necrosis, dehiscence, and hematoma. Implant loss was comparable across the cohorts. Overall, prepectoral breast reconstruction using ADM leads to relatively low complication rates with the highest rates within the bADM cohort.

The 5-Factor Modified Frailty Index as a Predictor of 30-day Complications in Pressure Ulcer Repair.

BACKGROUND: The 5-item modified frailty index (mFI-5) is a validated tool to assess postoperative risks in older surgical candidates. We sought to compare the predictive ability of mFI-5 to its individual components and other established risk factors for complications in flap reconstruction of late-stage pressure ulcer repair. METHODS: The 2012 to 2018 American College of Surgeons National Surgical Quality Improvement Project (ACS-NSQIP) database was queried for pressure ulcer diagnosis and reconstructive flap repair procedures. Univariate and multivariate regression analysis models were used to assess how mFI-5, the components of the mFI-5 (functional status before surgery, diabetes, history of chronic obstructive pulmonary disease, history of congestive heart failure, and history of hypertension requiring medicine), and other factors commonly used to risk-stratify (age, obesity, ASA classification, and history of smoking) were associated with complications. RESULTS: 35.1% of the total 1254 flap reconstructive procedures for pressure ulcer repair experienced complications. Most cases had at least one of the five mFI-5 factors in both the complication (42.7%) and no complication (45.7%) cohorts. Compared with the factors making up the mFI-5 score and other common variables used to risk-stratify, mFI-5 was significantly associated with complications in the univariate (OR 1.17, CI 1.03 - 1.33; P = 0.02) and multivariate analysis (OR 1.16, CI 1.02 - 1.34; P = 0.043). CONCLUSIONS: The mFI-5 is a useful predictor of postoperative outcomes in patients undergoing reconstructive flap surgery for pressure ulcer injuries compared to other historically considered risk factors for surgical complications.

2011 ACGME Duty Hour Limits had No Association With Breast Reconstruction Complications.

BACKGROUND: In 2011, the Accreditation Council for Graduate Medical Education (ACGME) instituted further duty hour restrictions in response to concerns over long work hours and sleep deprivation in trainees and their effects on patient outcomes. The effect of duty hour restrictions on complications after breast reconstruction procedures has not been clarified. MATERIALS AND METHODS: A retrospective cross-sectional analysis was designed. The National Inpatient Sample database was queried in the 2 y before and 2 y after the 2011 duty hour changes. Patients undergoing breast reconstruction, the most common elective admission diagnosis for plastic surgery patients, were selected for analysis. Patient groups were separated by teaching hospitals (THs) and nonteaching hospitals and by pre- and post-ACGME change periods. Surgical complication rates, length of stay, and procedures were analyzed using complex survey-weighted univariate and multivariate logistic regression analysis, with additional sensitivity analysis applied. RESULTS: The number of procedures did not vary significantly in the period after duty hour restrictions in THs (n = 46,188, pre-ACGME versus n = 48,980, post-ACGME). Overall complication rates in teaching (9.54%, pre-ACGME versus 9.04%, post-ACGME; P = 0.561) and nonteaching hospitals (8.54%, pre-ACGME versus 7.70%, post-ACGME; P = 0.319) did not significantly change after the implementation of duty hour changes. On multivariate analysis, surgery performed in resident THs after duty hour changes was not associated with a significant change in overall (odds ratio [OR], 1.03; 95% confidence interval [95% CI], 0.77-1.37; P = 0.857) breast-specific complications (OR, 1.06; 95% CI, 0.77-1.46; P = 0.731) or general complications (OR, 1.11; 95% CI, 0.80-1.54; P = 0.541). CONCLUSIONS: Duty hour restrictions enacted in 2011 were not associated with postoperative complications after breast reconstruction.

A Nationwide Analysis of Early and Late Readmissions following Free Tissue Transfer for Breast Reconstruction.

BACKGROUND: Traditionally, surgical quality outcomes are assessed using a 30-day postoperative window. For breast cancer patients undergoing free tissue transfer for breast reconstruction, we sought to describe the distribution of and specific risk factors for early and late readmissions within a 0- to 90-day postoperative period. PATIENTS AND METHODS: The Nationwide Readmissions Database was used to conduct a retrospective cohort study. Breast cancer patients undergoing free tissue transfer for breast reconstruction were identified using International Classification of Diseases -9 diagnosis and procedure codes. Ninety-day readmissions related to infection or wound complications were identified. Univariable and multivariable logistic regression models were used to identify patient risk factors for readmissions that occurred early (0-30 days) and late (31-90 days) after their index procedure. RESULTS: In the weighted sample, we identified approximately 7,305 free flap breast reconstructions and a surgical wound-related readmission rate of 4.3% (n = 312): 65.4% of the readmissions occurred early while 34.6% occurred late after surgery. The mean days to readmission was 26, and 75% of all readmissions occurred within the first 36 days after surgery. Variables independently associated with readmissions during the 0- to 90-day postoperative period included: history of chronic obstructive pulmonary disease (p = 0.036), hypertension (p = 0.03), obesity (p ≤ 0.001), and history of smoking (p = 0.004). The variables independently associated with the early readmission period were the same as those identified for the 0- to 90-day postoperative period. The variables independently associated with late readmissions were different: history of depression (p = 0.001) and history of smoking (p = 0.001). CONCLUSION: The conventional 30-day hospital readmission rate classically used as a quality metric is overlooking a significant portion of admissions after free flap-based breast reconstruction. Different variables were found to be associated with readmission in the early versus late cohorts. Interventions targeting these variables could decrease readmissions and their associated costs.

Abdominal Contouring and Male Gender: Analysis of Complications Using the National Quality Improvement Program Database.

BACKGROUND: Males represent a significant portion of patients undergoing abdominal contouring. Despite this, there are few studies examining the implication of gender on complications. OBJECTIVE: The aim of this study was to examine the association between gender and early postoperative outcomes in patients undergoing abdominal contouring procedures. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database (2006-2016) was queried to identify subjects undergoing panniculectomy or abdominoplasty. Minor and major complications were identified. Operative time and length of hospital stay were evaluated. A logistic regression model was used to examine associations between patient gender and adverse outcomes. RESULTS: Ten thousand four hundred seventy-three patients were identified. Of these, 4369 underwent abdominoplasties, and 6104 underwent panniculectomies. Males represented a higher percentage of the panniculectomy cohort (15.3% vs 9.2%). Males were older and generally had more comorbidities including diabetes, hypertension, chronic obstructive pulmonary disease, and elevated body mass index. Males also had a higher American Society of Anesthesiologists classification (P < 0.001). In the abdominoplasty cohort, male gender is an independent risk factor for any complication (odds ratio [OR], 1.3; confidence interval [CI], 1.16-1.45; P < 0.001) and major complications (OR, 1.52; CI, 1.01-2.29; P = 0.043). In the panniculectomy cohort, male gender is also an independent risk factor for any complication (OR, 1.47; CI, 1.24-1.75; P < 0.001) and major complications (OR, 1.43; CI, 1.12-1.83; P < 0.001). Males also had a significantly longer operative times in this cohort (171.3 vs 157.5 minutes; P < 0.001). CONCLUSIONS: Male gender is independently associated with minor and major complications in these patient populations. With this knowledge, plastic surgeons may be better able to identify higher-risk individuals and educate patients on their risk profile.

Immediate Bilateral Breast Reconstruction Using Abdominally Based Flaps: An Analysis of the Nationwide Inpatient Sample Database.

BACKGROUND: Bilateral mastectomy rates are increasing in the United States. The abdomen is the most common harvest site for autologous reconstruction. Nationwide data were examined to determine differences in hospital charges, length of stay (LOS), and early postoperative complications following immediate bilateral pedicled transverse rectus abdominis myocutaneous (pTRAM), free TRAM (fTRAM), deep inferior epigastric perforator (DIEP), and superficial inferior epigastric artery (SIEA) perforator flaps and were compared with unilateral reconstruction. METHODS: Patients who underwent immediate bilateral breast reconstruction using a single method of abdominally based reconstruction were identified using the 2009 to 2014 Nationwide Inpatient Sample Database. Outcomes included total hospital charges, LOS, and immediate postoperative complications. RESULTS: We identified 13,348 cases of bilateral mastectomy with a single type of immediate bilateral autologous flap reconstruction. The majority were bilateral DIEP flaps. Mean total cost for bilateral pTRAM, fTRAM, DIEP, and SIEA flaps was US $21,886.80, US $28,839.40, US $30,051.30, and US $33,784.90, respectively (p < 0.0001). Mean LOS for bilateral pTRAM, fTRAM, DIEP, and SIEA was 4.3, 4.9, 4.5, and 5.4 days, respectively (p = 0.0002), and hematoma rates were 1.93, 2.61, 3.68, and 16.59%, respectively, (p = 0.0001), whereas return to the operating room for vascular anastomosis revision was 0, 1.63, 1.99, and 19.07%, respectively (p < 0.0001). Cost is less for unilateral pTRAM, fTRAM, and DIEP flaps (p < 0.0001). LOS is shorter for unilateral fTRAM versus bilateral (p < 0.0001). No differences were appreciated between unilateral and bilateral hematoma and reoperation rates for any reconstruction (p > 0.1). CONCLUSION: Immediate complication rates were higher in bilateral free flaps compared with bilateral pedicled flaps. pTRAM and fTRAM flap reconstructions are still performed frequently with acceptable immediate results without considering long-term morbidity, aesthetics, and abdominal muscle function. Bilateral SIEA free flaps were associated with significantly higher total cost, LOS, and complication rates compared with other groups. Complications were similar between unilateral and bilateral reconstruction procedures. While cost is significantly greater for bilateral procedures compared with unilateral pTRAM, fTRAM, and DIEP flaps, it is not doubled.

Immediate Unilateral Breast Reconstruction using Abdominally Based Flaps: Analysis of 3,310 Cases.

BACKGROUND: The abdomen is the most common area from which tissue is harvested for autologous breast reconstruction. We sought to examine national data to determine the differences in total hospital charges, length of stay (LOS), and early postoperative complications following pedicled transverse rectus abdominis myocutaneous flap (pTRAM), free TRAM (fTRAM), deep-inferior epigastric perforator (DIEP), and superficial inferior epigastric artery perforator (SIEA) flaps. METHODS: The 2009-2013 Nationwide Inpatient Sample Database was used to identify patients who underwent a unilateral mastectomy and only one type of abdominally based autologous flap (pTRAM, fTRAM, DIEP, and SIEA) during the same hospital admission. Outcomes of interest included total charges, LOS, and complications including revision of vascular anastomosis and hematoma. RESULTS: A total of 3,310 cases were identified, corresponding to 15,991 abdominally based unilateral immediate breast reconstructions after standard weighting was applied; 5,079 (31.8%) were pTRAM flaps, 4,461 (27.9%) were fTRAM flaps, 6,206 (38.8%) were DIEP flaps, and 245 (1.5%) were SIEA flaps. The mean total charges for pTRAM, fTRAM, DIEP, and SIEA flaps were $17,765.5, $22,637.6, $25,814.6, and $26,605.2, respectively (p < 0.0001). The mean LOS for pTRAM, fTRAM, DIEP, and SIEA flaps were 96.5, 106.5, 106.7, and 108.9 hours, respectively (p = 0.002). The rates for return to the OR for the revision of a vascular anastomosis for pTRAM, fTRAM, DIEP, and SIEA were 0.0%, 1.72%, 2.66%, and 5.64%, respectively (p < 0.0001). CONCLUSIONS: There is variation in the total charges, LOS, and early complications between pTRAM, fTRAM, DIEP, and SIEA flap-based breast reconstruction. fTRAM, DIEP, and SIEA flaps incur higher hospital total charges, have longer lengths of stay, and experience more immediate complications compared with pTRAM. Well-designed prospective trials are required to better understand the findings from this study with the inclusion of other critical outcomes such as patient satisfaction, aesthetic results, and long-term outcomes such as abdominal wall morbidity.

Operative Time and Flap Failure in Unilateral and Bilateral Free Flap Breast Reconstruction.

BACKGROUND: There is an increasing trend toward bilateral breast reconstruction. Using the National Surgical Quality Improvement Program (NSQIP) database, we sought to understand the association between unilateral and bilateral free flap breast reconstruction and operative time and flap failure. METHODS: We selected a cohort of patients undergoing free flap breast reconstruction using the 2005 to 2010 NSQIP database. Cases were divided into unilateral and bilateral reconstruction. Subgroup analyses were performed dividing cases into delayed and immediate reconstruction. The effect of patient characteristics including age, body mass index (BMI), history of diabetes, and the American Society of Anesthesiologists' classification on operative time and flap failure was examined using univariable and multivariable regression models. Rates and odds ratios (OR) were reported using the multivariable gamma and logistic regression models, respectively. RESULTS: There were 691 free flap breast reconstructions performed in the cohort and 29.1% were bilateral cases. There was a 78-minute increase in the median operative time when comparing unilateral and bilateral reconstruction (p = 0.005). Patients undergoing bilateral reconstructions were generally younger and had fewer comorbidities compared with unilateral reconstructions. There was no significant association between bilateral reconstruction and flap failure. Immediate bilateral reconstructions had a significant increase in median operative time compared with immediate unilateral reconstructions (563 versus 480 minutes, p = 0.002) but no significant increase in operative time was noted when comparing delayed unilateral and delayed bilateral reconstructions. Prolonged operative time was associated with flap failure after adjusting for age and BMI (OR 1.17, p < 0.001). CONCLUSIONS: Bilateral free flap breast reconstruction can be performed safely despite an increase in operative time when compared with unilateral reconstruction.

Nipple Sparing Mastectomy in Patients With Prior Breast Scars: Is It Safe?

BACKGROUND: Nipple-sparing mastectomy (NSM) preserves the native skin envelope, including the nipple-areolar skin, and has significant benefits including improved aesthetic outcome and psychosocial well-being. Patients with prior breast scars undergoing NSM are thought to be at increased risk for postoperative complications, such as skin and/or nipple necrosis. This study describes our experience performing NSM in patients who have had prior breast surgery and aims to identify potential risk factors in this subset of patients. METHODS: A retrospective review of all patients undergoing nipple sparing mastectomy at The University of Utah from 2005 to 2011 was performed. Fifty-two patients had prior breast scars, for a total of 65 breasts. Scars were categorized into 4 groups depending on scar location: inframammary fold, outer quadrant, periareolar, and circumareolar. Information regarding patient demographics, social and medical history, treatment intent, and postoperative complications were collected and analyzed. RESULTS: Eight of the 65 breasts (12%) developed a postoperative infection requiring antibiotic treatment. Tobacco use was associated with an increased risk of infection in patients with prior breast scars (odds ratio [OR], 7.95; 95% confidence interval [CI], 1.37-46.00; P = 0.0206). There was a 13.8% rate of combined nipple and skin flap necrosis and receipt of chemotherapy (OR, 5.00; CI, 1.11-22.46; P = 0.0357) and prior BCT (OR, 12.5; CI, 2.2-71.0; P = 0.004) were found to be associated with skin flap or NAC necrosis. CONCLUSIONS: Nipple-sparing mastectomy is a safe and viable option for patients with a prior breast scar. Our results are comparable to the published data in patients without a prior scar. Caution should be exercised with patients who have a history of tobacco use or those requiring chemotherapy because these patients are at increased risk for infection and NAC/skin flap necrosis, respectively, when undergoing NSM in the setting of a prior breast scar.

Unplanned reoperations after microvascular free tissue transfer: An analysis of 2,244 patients using the american college of surgeons national surgical quality improvement program database.

PURPOSE: Our intent was to evaluate unplanned reoperations as a quality indicator for microvascular free tissue transfer (MFTT). METHODS: The National Surgical Quality Improvement Program database was used to identify MFTT cases from January 2012 to December 2013. Multivariate logistic regression models were used to determine risk factors for unplanned reoperations. RESULTS: We identified 2,244 MFTT cases. There were 290 associated unplanned reoperations (12.92%). There was a threefold increase in the rate of complications when patients underwent reoperation (58.28% vs 18.12%, p < 0.0001). Head and neck reconstructions had the highest rate of reoperations (18.04%). Most reoperations were debridements (38.28%), followed by microvascular procedures (28.97%) and flap revisions (26.55%). American Society of Anesthesiologist (ASA) classification ≥3 [OR 1.565, 95% CI (1.204, 2.034), p = 0.0008] and prolonged operative time [OR 1.597, 95% CI (1.221, 2.089), p = 0.0006] were significant independent risk factors for reoperations. CONCLUSIONS: Unplanned reoperations are a useful quality indicator for MFTT. ASA classification ≥3 and prolonged operative time were risk factors associated with an increased risk for unplanned reoperations. © 2015 Wiley Periodicals, Inc. Microsurgery 37:184-189, 2017.

An analysis of free flap failure using the ACS NSQIP database. Does flap site and flap type matter?

PURPOSE: We sought to use the NSQIP database to determine the national rate and predictors of free flap failure based upon flap sites and flap types. METHODS: Free flaps were identified using the 2005-2010 NSQIP database. We examined overall flap failure rates as well as failure rates based upon flap sites (head and neck, extremities, trunk, and breast) and flap types (muscle, fascial, skin, bone, and bowel flaps). Univariate and multivariate analyses were used to determine predictors of flap failure. RESULTS: There were 1,187 microvascular free tissue transfers identified. The overall flap failure rate was 5.1%. Head and neck flaps had the highest rate of free flap failure at 7.7%. Prolonged operative time is an independent predictor of flap failure for all free flaps (OR: 2.383, P = 0.0013). When examining predictors of failure by flap site, free flaps to the breast with prolonged operative time are independently associated with flap failure (OR: 2.288, P = 0.0152). When examining predictors of flap failure by flap type, muscle based free flaps with an ASA classification ≥3 are associated with flap failure (P = 0.0441). CONCLUSIONS: Risk factors for free flap failure differ based upon flap site and flap type. Prolonged operative time is an independent risk factor for the failure of free flaps used for breast reconstruction. An ASA classification ≥3 is associated with the failure of free muscle based flaps. Our findings identify actionable areas that may help to improve free flap success.

The Effect of Radiation on Complication Rates and Patient Satisfaction in Breast Reconstruction using Temporary Tissue Expanders and Permanent Implants.

The optimal method of reconstruction following mastectomy for breast cancer patients receiving radiation therapy (RT) is controversial. This study evaluated patient satisfaction and complication rates among patients who received implant-based breast reconstruction. The specific treatment algorithm analyzed included patients receiving mastectomy and immediate temporary tissue expander (TE), followed by placement of a permanent breast implant (PI). If indicated, RT was delivered to the fully expanded TE. Records of 218 consecutive patients with 222 invasive (85%) or in situ (15%) breast lesions from the Salt Lake City region treated between 1998 and 2009 were retrospectively reviewed, 28% of whom received RT. Median RT dose was 50.4 Gy, and 41% received a scar boost at a median dose of 10 Gy. Kaplan-Meier analyses were performed to evaluate the cumulative incidence of surgical complications, including permanent PI removal. Risk factors associated with surgical events were analyzed. To evaluate cosmetic results and patient satisfaction, an anonymous survey was administered. Mean follow-up was 44 months (range 6-144). Actuarial 5-year PI removal rates for non-RT and RT patients were 4% and 22%, respectively. On multivariate analysis (MVA), the only factor associated with PI removal was RT (p = 0.009). Surveys were returned describing the outcomes of 149 breasts. For the non-RT and RT groups, those who rated their breast appearance as good or better were 63% versus 62%, respectively. Under 1/3 of each group was dissatisfied with their reconstruction. RT did not significantly affect patient satisfaction scores, but on MVA RT was the only factor associated with increased PI removal. This reconstruction technique may be considered an acceptable option even if RT is needed, but the increased complication risk with RT must be recognized.

A model for university-based international plastic surgery collaboration builds local sustainability.

This article aimed to assess the sustainability from collaboration between international plastic surgery consultants and a hospital of a developing country in the promotion and delivery of quality health care to the local population. Humanitarian medical missions have evolved in structure and volume during the last 40 years. Medical mission trips were initially designed to treat local populations and help decrease the burden of disease. A limited number of the local population benefited from the mission. Some mission trips evolved from not only treating the local population but also teaching local physicians. These trips produced some local sustainability. Host physicians carried on a broader range of care after the mission trip had departed. Further evolution of these medical trips involves not only care and teaching but also involvement of host medical students and residents. Regularly scheduled Internet-based consultations and educational conferences expand the educational opportunities. The sustainability of medical trips based on this model is maximized. This process still has limitations: a limited number of the local population are treated during the in-country 1-week visits, Internet reliability may limit the transmission or quality of conferences, and differences in hospital resource availability may limit transference of US techniques to other hospitals.
