RESUMO

Primary lymphedema is a heterogeneous group of conditions encompassing all lymphatic anomalies that result in lymphatic swelling. Primary lymphedema can be difficult to diagnose, and diagnosis is often delayed. As opposed to secondary lymphedema, primary lymphedema has an unpredictable disease course, often progressing more slowly. Primary lymphedema can be associated with various genetic syndromes or can be idiopathic. Diagnosis is often clinical, although imaging can be a helpful adjunct. The literature on treating primary lymphedema is limited, and treatment algorithms are largely based on practice patterns for secondary lymphedema. The mainstay of treatment focuses on complete decongestive therapy, including manual lymphatic drainage and compression therapy. For those who fail conservative treatment, surgical treatment can be an option. Microsurgical techniques have shown promise in primary lymphedema, with both lymphovenous bypass and vascularized lymph node transfers demonstrating improved clinical outcomes in a few studies.

RESUMO

INTRODUCTION: Maxillary cancer is relatively rare but devastating for those affected with the disease. For patients who require suprastructural or total maxillectomy for oncologic resection, the resection of the orbital floor can be challenging to reconstruct. The serratus-rib flap is a well-known and useful method of head and neck reconstruction, albeit infrequently used. However, the serratus-rib flap has not previously been described for reconstruction of the orbital floor and has the potential to provide excellent globe support after orbital floor resection in patients after undergoing maxillectomy. METHODS: We retrospectively reviewed all patients who had undergone orbital floor reconstruction using the serratus-rib osteomyofascial free flap by the senior author throughout their career. Surgical technique, postoperative course, complications, and additional required procedures were evaluated. RESULTS: Six patients were found to have undergone the serratus-rib osteomyofascial free flap for orbital floor reconstruction. Average follow-up was 26.7 months from initial surgery. Fifty percent of patients had later minor revision surgery such as fat grafting or scar revision. No patients had any significant complications, and all patients were noted to have good ocular function without diplopia postoperatively. CONCLUSION: The serratus-rib osteomyofascial free flap is an efficacious method for reconstruction of the orbital floor after oncologic resection. Surgeons should consider this flap when performing orbital floor reconstruction, particularly when dead space also needs to be filled with the use of a free flap.

RESUMO

Postmastectomy pain syndrome (PMPS) is defined as chronic pain after breast cancer surgery lasting greater than 3 months and has been shown to affect up to 60% of breast cancer patients. Substantial research has been performed to identify risk factors and potential treatment options, although the exact cause of PMPS remains elusive. As breast reconstruction becomes increasingly popular, plastic surgeons are likely to encounter more patients presenting with PMPS. This article summarizes current evidence on risk factors and treatment options for PMPS and highlights further areas of study.

RESUMO

BACKGROUND: Vascularized lymph node transfer (VLNT) is a well-established method for the surgical management of refractory extremity lymphedema. Generally, donor lymph nodes are harvested from the axilla, groin, or supraclavicular area. However, these sites offer their own disadvantages and introduce risk for inducing lymphedema at the surgical donor site. In our experience, the jejunal mesentery can be an excellent source of lymph nodes without the risk of donor site lymphedema. Long term complications are unknown for this procedure; we report our experience, complication rates, and lessons learned. METHODS: A retrospective review was performed for all patients at our institution undergoing surgical treatment of lymphedema using jejunal mesenteric VLNT from February 2015 to February 2018. Demographic data, length of follow up, and surgical complications were reviewed. RESULTS: Twenty-nine patients have undergone jejunal VLNT at our institution during the three-year study period, with a total of 30 transfers. Five patients had a concurrent omental lymph node transfer. Average length of follow up was 17.6 months (range 1.0-36.8 months). There was one flap loss in this time frame (3.3%). Four patients developed hernias post-operatively (13.8%), and three had nonoperative small bowel obstructions (10.3%). One patient had a postoperative wound infection at the abdominal incision (3.4%). CONCLUSIONS: Jejunal VLNT can be an effective option for surgical treatment of lymphedema, without the risk of postoperative donor site lymphedema. Patients and surgeons should be aware of the risks of hernia and small bowel obstruction with this method compared to other lymph node sources.

RESUMO

BACKGROUND: Physician assistants (PAs) are commonly employed in plastic surgery. However, limited data exist on their impact, which may guide decisions regarding how best to integrate them into practice. METHODS: A review of the practices of 2 breast reconstructive surgeons was performed. A comparison was made between a 1-year period before to a 1-year period after the addition of a PA into practice. The practice model was a one-to-one pairing of a plastic surgeon and a PA. RESULTS: A total of 4141 clinic encounters and 1356 surgical cases were reviewed. After the addition of PAs, there was a significant increase in relative value units (1057 vs 1323 per month per surgeon, P < 0.001). Operative times were similar with and without PAs (P = 0.45). However, clinic encounter times for surgeons were shorter for all visit types when patients were first seen by a PA before the surgeon: global follow-up (P = 0.03), other follow-up (P = 0.002), consultation (P = 0.76), and preoperative (P = 0.02), translating to 9 additional patients seen per day. Charges (P = 0.001) and payments (P = 0.007) also increased, which offset the cost of using a PA. However, the financial contribution from PA involvement as first assistant in surgery was limited (5.2%). The peak effect of PAs was observed between the third and fourth quarters. CONCLUSIONS: In breast reconstruction, PAs primarily enhance the efficiency of plastic surgeons, particularly in the clinic, with downstream clinical and financial gains of an indirect nature for surgeons.

RESUMO

Massive localized lymphedema is a monstrous tumefactive pseudosarcoma seen in middle-aged morbidly obese adults. Since its initial description in 1998, the etiology remains unknown, although associations with trauma, surgeries, and hypothyroidism have been reported. Herein, we report the largest study of massive localized lymphedema and expand upon its clinicopathologic features. Fifty-four cases from 46 patients were retrospectively identified from the institutional archives of The Ohio State University Wexner Medical Center between 2002 and 2015. Forty-six patients (21 males and 25 females, mean age 50 years) presented with large masses developing over a 5-60-month period. The majority of patients were Caucasian (n=39). All patients were obese with a mean weight of 384.7 lb and a mean body mass index of 59.6 kg/m(2). Thirty-six patients had a history of atherosclerotic cardiovascular disease and diabetes mellitus type 2 was present in 22 patients. Eight patients had multifocal massive localized lymphedema. The sites included thigh (n=33), abdomen (n=17), suprapubic region (n=1), mons pubis (n=6), scrotum (n=2), perianal region (n=1), and right flank (n=1). Mostly, the clinical impression was benign processes, including pannus or lymphedema pseudotumor. Grossly, the mean weight was 8237 g and the mean size was 53.2 cm. Histologically, eight cases showed a unique pattern of dystrophic calcifications mimicking hyperchromatic, atypical nuclei that might lead to misdiagnosis of liposarcoma, four cases showed focal metaplastic ossification, and three cases showed multinucleated cells in addition to prototypic features of massive localized lymphedema. We report that this is the largest series of massive localized lymphedema. This is a lesion mostly seen in morbidly obese patients and the thigh is the most common site of involvement. We note a marked racial predilection for Caucasians and a tendency towards multiplicity. We suggest that obesity itself and the related metabolic syndrome have an important role in its pathogenesis.

RESUMO

INTRODUCTION: A knowledge gap exists regarding factors to optimize limb salvage and function following oncologic resection. METHODS: We conducted a retrospective review of all free flaps performed for upper extremity (UE) and lower extremity (LE) salvage from 2000 to 2012. RESULTS: Overall, 220 patients underwent free-flap reconstruction for limb salvage (UE: 64, and LE: 156). Flaps were classified as muscle-only (n = 77), myocutaneous (MC; n = 67), or fasciocutaneous (FC; n = 76). Smoking, diabetes, peripheral vascular disease, and prior chemotherapy or radiation had no impact on complications, while osteomyelitis significantly increased the risk of infection (odds ratio [OR] 19.5, confidence interval [95% CI] 3.77-100.64; p = 0.0004), wound healing complications (OR 7.51, 95% CI 2.21-25.49; p = 0.001), and amputation (OR 4.63, 95% CI 1.41-15.19; p = 0.01). Hardware increased the risk for flap loss (OR 4.92, 95% CI 1.33-18.23; p = 0.017). MC and FC flaps had increased risks for hematoma (p = 0.02) and reoperation for microvascular complications (p = 0.005) but were at lower risk for infection (OR 0.14, 95% CI 0.02-0.87; p = 0.03) compared with muscle-only flaps. There were a total of seven total flap losses (3.2%), with significantly increased risks for MC/FC flaps (OR 2.58, 95% CI 1.06-6.26; p = 0.03). For LE, 103 patients (66.3%) were fully ambulatory, while 23 (14.7%) were ambulatory with assistance (mean Musculoskeletal Tumor Society score (MSTS) 80.2, and Karnofsky score 84.0). For UE, 49 patients (76.6%) were able to perform their activities of daily living independently (mean MSTS 80.2, and Karnofsky score 86.0). Overall, 190 patients (86.4%) were successfully salvaged. CONCLUSIONS: Free flaps can be performed reliably for limb salvage following tumor extirpation. While MC/FC flaps demonstrated improved postoperative function, they were at significantly higher risk for take-backs and total flap loss.

RESUMO

Bony free flap reconstruction of the facial skeleton remains a challenging area of reconstructive surgery. Despite technological advances that have aided planning and execution of these procedures, surgical inaccuracy is not insignificant. One source of error that has not been wholly addressed is that attributable to a human operator. In this study, we investigate the feasibility and accuracy of performing osteotomies robotically in pre-programmed fashion for fibula free flap mandible reconstruction as a method to reduce inaccuracies related to human error. A mandibular defect and corresponding free fibula flap reconstruction requiring six osteotomies were designed on a CAD platform. A methodology was developed to translate this virtual surgical plan data to a robot (KUKA, Augsburgs, Germany), which then executed osteotomies on three-dimensional (3D) printed fibula flaps with the aid of dynamic stereotactic navigation. Using high-resolution computed tomography, the osteotomized segments were compared to the virtually planned segments in order to measure linear and angular accuracy. A total of 18 robotic osteotomies were performed on three 3D printed fibulas. Compared to the virtual preoperative plan, the average linear variation of the osteotomized segments was 1.3 ± 0.4 mm, and the average angular variation was 4.2 ± 1.7°. This preclinical study demonstrates the feasibility of pre-programmed robotic osteotomies for free fibula flap mandible reconstruction. Preliminarily, this method exhibits high degrees of linear and angular accuracy, and may be of utility in the development of techniques to further improve surgical accuracy.

RESUMO

BACKGROUND: Few studies on tongue reconstruction provide a comprehensive, multidisciplinary analysis examining defect size, flap selection, function, and long-term survival. This report presents the largest study in the literature evaluating free flap reconstruction after glossectomy. METHODS: A retrospective review of patients undergoing free flap glossectomy reconstruction from 2000 to 2012 was performed. RESULTS: In this review, 268 patients were identified. Resections involving the tongue only included 59 partial glossectomies, 86 hemiglossectomies, 28 subtotal glossectomies, and 24 total glossectomies. Glossectomies performed with mandibulectomies were analyzed independently for speech and swallowing function (32 partial glossectomies, 18 hemiglossectomies, 8 subtotal glossectomies, and 13 total glossectomies with mandibulectomy). A total of 299 free flaps were performed, with 30 patients receiving two free flaps. Multivariate analysis demonstrating smoking (p = 0.018), composite resections (p < 0.001), and larger resections (total and subtotal glossectomies; p < 0.001) were associated with significantly worse speech results. Advanced age (p = 0.002), radiation (p = 0.003), and larger or composite resections had significantly worse swallowing function (p < 0.001). Patients with a persistent tracheostomy had significantly worse speech and swallowing function (p < 0.001), whereas innervated flaps were associated with superior speech (p = 0.049) and better swallowing function (p = 0.004). The surgical complication rate was 23.5 %, with only one total flap loss. Tumor stage (p = 0.003), positive margins (p < 0.001), lymphovascular invasion (p = 0.023), and chemotherapy (p < 0.001) were associated with significantly worse overall survival. The median overall survival time was 50.5 months (range 39-79 months). CONCLUSIONS: Although comorbidities and the extent of resection impair both speech and swallowing, reconstruction, particularly with innervated free flaps, still affords the majority of patients' reasonable function.

RESUMO

BACKGROUND: Patients with facial cancers can experience disfigurement as they may undergo considerable appearance changes from their illness and its treatment. Individuals with difficulties adjusting to facial cancer are concerned about how others perceive and evaluate their appearance. Therefore, it is important to understand how humans perceive disfigured faces. We describe a new strategy that allows simulation of surgically plausible facial disfigurement on a novel face for elucidating the human perception on facial disfigurement. METHOD: Longitudinal 3D facial images of patients (N = 17) with facial disfigurement due to cancer treatment were replicated using a facial mannequin model, by applying Thin-Plate Spline (TPS) warping and linear interpolation on the facial mannequin model in polar coordinates. Principal Component Analysis (PCA) was used to capture longitudinal structural and textural variations found within each patient with facial disfigurement arising from the treatment. We treated such variations as disfigurement. Each disfigurement was smoothly stitched on a healthy face by seeking a Poisson solution to guided interpolation using the gradient of the learned disfigurement as the guidance field vector. The modeling technique was quantitatively evaluated. In addition, panel ratings of experienced medical professionals on the plausibility of simulation were used to evaluate the proposed disfigurement model. RESULTS: The algorithm reproduced the given face effectively using a facial mannequin model with less than 4.4 mm maximum error for the validation fiducial points that were not used for the processing. Panel ratings of experienced medical professionals on the plausibility of simulation showed that the disfigurement model (especially for peripheral disfigurement) yielded predictions comparable to the real disfigurements. CONCLUSIONS: The modeling technique of this study is able to capture facial disfigurements and its simulation represents plausible outcomes of reconstructive surgery for facial cancers. Thus, our technique can be used to study human perception on facial disfigurement.

RESUMO

BACKGROUND: Pharyngoesophageal (PE) reconstruction is complex, with a diverse set of reconstructive considerations. This large series examines the impact of various defect characteristics and reconstructive modalities on outcomes. PATIENTS AND METHODS: A retrospective review identified 349 cases from 2000 to 2011. Patients were grouped according to defect extent and location. Groups were compared by comorbidities, flap type, donor and recipient site complications, postoperative diet, and tracheoesophageal speech. RESULTS: Of 349 cases, 193 (55.3%) PE defects were circumferential and 156 (44.7%) were partial. The majority of defects resulted from laryngopharyngectomy (72.5%), most reconstructed with the anterolateral thigh flap (60%). There were 15.5% total esophagectomies, all of which received supercharged jejunal flaps. Of 349 patients, 81 patients (23.2%) had recipient site complications and 51 patients (14.6%) had donor site complications. The fistula rate trended higher in circumferential defects (11 vs. 6%, p = 0.144), and the stricture rate was significantly higher (9.3 vs. 3.8%, p = 0.044). In total, 302 patients (86.5%) had an oral diet after reconstruction, 64 (18%) of whom required supplemental tube feeds. Among 147 patients (42%) who received tracheoesophageal puncture (TEP), 19 (12.9%) eventually failed. Approximately 87% of patients with TEPs achieved fluent speech. The 5-year survival was low for all groups, ranging from 0 to 35%. CONCLUSIONS: PE reconstruction can be performed safely, and most patients will achieve functional speech and swallowing. Swallowing function is worse when the larynx is removed, and the stricture rate is higher with circumferential defects. Specific technical measures can reduce the rate of common complications. LEVEL OF EVIDENCE: The level of evidence of this article was level III.

RESUMO

Autologous breast reconstruction is an increasingly popular method of reconstruction for breast cancer survivors. While deep inferior epigastric perforator (DIEP) flaps are the gold standard, not all patients are ideal candidates for DIEP flaps due to low BMI, body habitus, or previous abdominal surgery. In these patients, complex autologous breast reconstruction can be performed, but there is a limited number of programs around the world due to high technical demand. Given the increased demand and need for complex autologous flaps, it is critical to build programs to increase patient access and teach future microsurgeons. In this paper, we discuss the steps, pearls, and preliminary experience of building a complex autologous breast reconstruction program in a tertiary academic center. We performed a retrospective chart review of patients who underwent starting the year prior to the creation of our program. Since the start of our program, a total of 74 breast mounds have been reconstructed in 46 patients using 87 flaps. Over 23 months, there was a decrease in median surgical time for bilateral reconstruction by 124 min (p = 0.03), an increase in the number of co-surgeon cases by 66% (p < 0.01), and an increase in the number of complex autologous breast reconstruction by 42% (p < 0.01). Our study shows that a complex autologous breast reconstruction program can be successfully established using a multi-phase approach, including the development of a robust co-surgeon model. In addition, we found that a dedicated program leads to increased patient access, decreased operative time, and enhancement of trainee education.

RESUMO

Despite advances in opioid-sparing pain management, postdischarge opioid overprescribing in plastic surgery remains an issue. Procedure-specific prescribing protocols have been implemented successfully in other surgical specialties but not broadly in plastic surgery. This study examined the efficacy of procedure-specific prescribing guidelines for reducing postdischarge opioid overprescribing. Methods: A total of 561 plastic surgery patients were evaluated retrospectively after a prescribing guideline, which recommended postdischarge prescription amounts based on the type of operation, was introduced in July 2020. Prescription and postdischarge opioid consumption amounts before (n = 428) and after (n = 133) guideline implementation were compared. Patient satisfaction and prescription frequency of nonopioid analgesia were also compared. Results: The average number of opioid pills per prescription decreased by 25% from 19.3 (27.4 OME) to 15.0 (22.7 OME; P = 0.001) after guideline implementation, with no corresponding decrease in the average number of postdischarge opioid pills consumed [10.6 (15.1 OME) to 8.2 (12.4 OME); P = 0.147]. Neither patient satisfaction with pain management (9.6-9.6; P > 0.99) nor communication (9.6-9.5; P > 0.99) changed. The rate of opioid-only prescription regimens decreased from 17.9% to 7.6% (P = 0.01), and more patients were prescribed at least two nonopioid analgesics (27.5% to 42.9%; P = 0.003). The rate of scheduled acetaminophen prescription, in particular, increased (54.7% to 71.4%; P = 0.002). Conclusions: A procedure-specific prescribing model is a straight-forward intervention to promote safer opioid-prescribing practices in plastic surgery. Its usage in clinical practice may lead to more appropriate opioid prescribing.

RESUMO

BACKGROUND: Our ability to guide cells in biomaterials for in vivo bone repair is limited and requires novel strategies. Short-interfering RNA (siRNA) allows the regulation of multiple cellular pathways. Core binding factor alpha 1 (Cbfa1) and hypoxia-inducible factor 1 (HIF-1) pathways can be modulated to direct bone formation via siRNA against guanine nucleotide-binding protein alpha-stimulating activity polypeptide 1 (siGNAS1) and prolyl hydroxylase domain-containing protein 2 (siPHD2), respectively. QUESTIONS/PURPOSES: We determined whether the administration of siGNAS1 and siPHD2 in mesenchymal stem cells (MSCs) promotes osteogenic phenotype, the dose-dependent effects of siGNAS1 on MSC differentiation to osteogenic phenotype, and whether the two siRNAs promote bone formation in vivo. METHODS: siRNAs were administered to MSCs at Day 0, and protein expression of bone-specific markers was assessed at Days 1, 2, and 4 (n = 3/group/time point). In an in vivo model using seven sheep, chambers containing silk fibroin-chitosan (SFCS) scaffolds with siRNA were implanted over the periosteum and harvested at Days 7, 21, 36, and 70 (n = 4/group/time point, except at Day 70 [n = 2]) to assess bone formation. RESULTS: siGNAS1 promoted collagen I and osteopontin expression, whereas siPHD2 had no effect in vitro. Dose-dependent effects of siGNAS1 on ALP expression were maximal at Day 1 for 10 µg/mL and Day 4 for 100 µg/mL. In vivo, by Day 70, mean bone volume increased compared to Day 7 for siGNAS1-SFCS (47.8 versus 1.8 mg/mL) and siPHD2-SFCS (61.3 versus 1.5 mg/mL). CONCLUSIONS: Both siPHD2 and siGNAS1 support bone regeneration in vivo, whereas only siGNAS1 regulates bone phenotype in MSCs in vitro.

RESUMO

BACKGROUND: Oncologic defects resulting from extremity amputations are often extensive and require substantial soft tissue for reconstruction. METHODS: A review of all patients, who underwent an external hemipelvectomy, forequarter amputation, or hindquarter amputation from 2001 to 2010 at the MD Anderson Cancer Center, was performed. RESULTS: A total of 50 patients were identified; of them, 21 underwent external hemipelvectomy, 22 had forequarter amputation, and 7 had hindquarter amputation. The mean defect size was 644 cm; defects were repaired using fillet flaps (n = 22, 44%), free flaps (n = 4, 8%), or local/regional flaps (n = 24, 48%). Of the fillet flaps, 16 were free flaps and the remaining were pedicled flaps. In all, 29 patients (58%) received preoperative radiation therapy, and 26 patients (52%) received preoperative chemotherapy. Two patients (4%) received postoperative radiation therapy, and 1 patient (2%) received postoperative chemotherapy. Three patients received both pre- and postoperative radiation therapy, and 10 patients were treated with both pre- and postoperative chemotherapy. Patients undergoing free flap reconstruction had significantly fewer complications compared with patients reconstructed using other modalities (2/20 vs. 13/30; P = 0.003). The majority of patients achieved excellent postoperative function, with 73% of upper extremity patients functioning independently and 57% of lower extremity amputees ambulating. CONCLUSIONS: Reconstruction for extensive defects following oncologic extremity amputation is often optimally done using free tissue transfer, particularly by salvaging "spare parts" from the amputated limb for a free fillet flap.

RESUMO

Medicinal leech therapy (MLT) to salvage venous congestion in native skin and local flaps is commonly practiced. However, the role of MLT in compromised regional and free flaps remains unclear. Leeches were used in 39 patients to treat venous congestion in native skin (n = 5), local flaps (n = 6), regional flaps (n = 14), and free flaps (n = 14). There were no total losses in patients with compromised native skin or local flaps. One patient who had received a radial forearm free flap expired before flap outcome could be assessed, and was excluded from analysis. Of the remaining 27 regional and free flaps, 33.3% were salvaged, 33.3% were partially salvaged, and 33.3% were lost. Means of 38.3 ± 34.0, 101.0 ± 11.2, and 157.9 ± 224.4 leeches and 1.7 ± 3.6, 3.2 ± 4.4, and 5.6 ± 5.2 units of blood were required for the salvaged, partially salvaged, and lost groups, respectively. Twenty-two patients required blood transfusion (57.9%). No patients developed wound infection with Aeromonas hydrophilia. Two patients developed donor site hematomas, and four patients developed recipient site hematomas. MLT is efficacious in congested native skin and local flaps. Some regional and free flaps can be totally or partially salvaged. However, the morbidity of MLT must be weighed against the risks of flap loss.

RESUMO

At our institution, multimodal opiate-sparing pain management is the cornerstone of our enhanced recovery program for autologous breast reconstruction. The purpose of this study was to compare postoperative outcomes and pain control metrics following implementation of an enhanced recovery program with two different regional analgesia approaches. METHODS: This retrospective cohort study identified 145 women who underwent autologous breast reconstruction from 2015 to 2017. Three groups were included: historical control patients (n = 46) and enhanced recovery patients that received multimodal pain management including a postoperative transversalis abdominis plane block with either a continuous local anesthetic catheter (n = 60) or a single-shot of liposomal bupivacaine (n = 39). The primary outcome was pain scores in the first three postoperative days. Secondary outcomes were opioid consumption in oral morphine equivalents and length of stay. RESULTS: Postoperative pain scores were similar across all three groups until postoperative day 3. Length of stay was significantly shorter in both of the enhanced recovery cohorts (3.0 [3.0, 4.0]) compared with control patients (4.0 [4.0, 5.0], P < 0.001). Likewise, average total oral morphine equivalents consumption was significantly reduced in enhanced recovery patients (continuous catheter 215.9 (95% CI, 165.4-266.3); liposomal bupivacaine 211.0 (95% CI, 154.8-267.2); control 518.4 (95% CI 454.2-582.7), P < 0.001). Neither length of stay (P = 0.953), nor oral morphine equivalents consumption (P = 0.883) differed by type of regional analgesia. CONCLUSION: Compared with control patients, both approaches to regional transversalis abdominis plane block analgesia as part of an opiate-sparing enhanced recovery pain management strategy were successful, but neither superior to the other.

RESUMO

Background: Pectoralis nerve blocks (PECS) have been shown in numerous studies to be a safe and effective method to treat postoperative pain and reduce postoperative opioid consumption after breast surgery. However, there are few publications evaluating the PECS block effectiveness in conjunction with multimodal analgesia (MMA) in outpatient breast surgery. This retrospective study aims to evaluate the efficacy of PECS's blocks on perioperative pain management and opioid consumption. Methods: We conducted a retrospective study to assess the efficacy of preoperative PECS block in addition to preoperative MMA (oral acetaminophen and/or gabapentin) in reducing opioid consumption in adult female subjects undergoing outpatient elective breast surgery between 2015 and 2020. A total of 228 subjects were included in the study and divided in two groups: PECS block group (received PECS block + MMA) and control Group (received only MMA). The primary outcome was to compare postoperative opioid consumption between both groups. The secondary outcome was intergroup comparisons of the following: postoperative nausea and vomiting (PONV), incidence of rescue antiemetic medication, PACU non-opioid analgesic medication required, length of PACU stay and the incidence of 30-day postoperative complications between both groups. Results: Two hundred and twenty-eight subjects (n = 228) were included in the study. A total of 174 subjects were allocated in the control group and 54 subjects were allocated in the PECS block group. Breast reduction and mastectomy/lumpectomy surgeries were the most commonly performed procedures (48% and 28%, respectively). The total amount of perioperative (intraoperative and PACU) MME was 27 [19, 38] in the control group and 28.5 [22, 38] in the PECS groups (p = 0.21). PACU opioid consumption was 14.3 [7, 24.5] MME for the control group and 17 [8, 23] MME (p = 0.732) for the PECS group. Lastly, the mean overall incidence of postsurgical complications at 30 days was 3% (N = 5), being wound infection, the only complication observed in the PECS groups (N = 2), and hematoma (N = 2) and wound dehiscence (N = 1) in the control group. Conclusion: PECS block combined with MMA may not reduce intraoperative and/or PACU opioid consumption in patients undergoing outpatient elective breast surgery.

RESUMO

The number of women diagnosed with breast cancer at a young age (≤30years) continues to rise. As young women present for breast cancer management with greater frequency, an accurate characterization of the differences in cancer treatments and reconstruction techniques is imperative to optimize care. Here, we sought to identify the reconstruction trends in this population of women ≤30years at time of breast cancer diagnosis. We retrospectively reviewed the charts of women aged ≤30years who underwent breast reconstruction at The University of Texas M.D. Anderson Cancer Center. We extracted data on the patients' diagnosis, adjuvant therapy, reconstructive choice, reason for reconstructive choice, and decision for contralateral prophylactic mastectomy (CPM). Over a 10-year period, 54 patients aged ≤30years underwent 77 breast reconstructions, including 30 microsurgical autologous tissue reconstructions and 34 tissue expander-based reconstructions. Donor site limitations, including insufficient abdominal tissue, restricted the number of patients eligible for abdominal based reconstruction despite the patients' interest in the latter. The rate of CPM was 43%, which was significantly higher than the national average of 8%, further complicating the possibility of total autologous reconstruction. Because of the high rate of bilateral mastectomy and innate donor tissue limitations, young, healthy women who are otherwise ideal candidates for free tissue transfer using the abdominal donor site undergo significantly more tissue expander reconstructions than expected. Implant-based reconstruction or donor sites other than the abdomen must be considered in this unique population.
