Negative Pressure Wound Therapy versus Conventional Dressing in Lower Limb Fractures: Systematic Review and Meta-analysis.

Gustilo 3 lower limb fractures represent a significant challenge because of high complication risk. Two management strategies are commonly used for wound coverage until final closure: negative pressure wound therapy (NPWT) and conventional wound dressing (CWD), also described as standard wound coverage without subatmospheric pressure. Understanding their relative effectiveness is essential to improve patient outcomes. The aim of this systematic review and meta-analysis was to compare the efficacy of NPWT and CWD in Gustilo 3 lower limb fracture management, with a focus on overall rates, superficial infection, and deep infection rates. A systematic review of medical research databases was conducted in accordance with PRISMA guidelines. Studies comparing NPWT with CWD for Gustilo 3 fractures were included. Data extraction and quality assessment were performed. Treatment with CWD was associated with significantly higher rates of overall infection [pooled risk ratio (RR): 0.33; 95% confidence interval (CI): 0.14-0.51] and pooled risk difference (RD: 0.27; 95% CI: 0.15-0.38), superficial infection (pooled RR: 0.35; 95% CI: 0.04-0.66), and deep infection (pooled RR: 0.20; 95% CI: 0.02-0.38) compared with NPWT treatment. Overall infection rate remained significantly higher in the CWD group after analyzing only open tibia fractures (pooled RR: 0.35; 95% CI: 0.21-0.48). Nonunion rate was significant higher in the CWD group (pooled RR: 0.30; 95% CI: 0.00-0.59). Flap failure rate was similar in both groups (pooled RR: 0.09; 95% CI: -0.05 to 0.23). NPWT appears to be a reasonable option for wound management in Gustilo 3 lower limb fractures in terms of infection rates.

Medial Femoral Condyle Free Flap: A Systematic Review and Proportional Meta-analysis of Applications and Surgical Outcomes.

Background: Recalcitrant bone nonunion and osseous defect treatment is challenging and often requires vascularized bone transfer. The medial femoral condyle flap has become an increasingly popular option for reconstruction. The study aims at reviewing its different applications and synthesizing its surgical outcomes. Method: A systematic review including all studies assessing surgical outcomes of free medial femoral condyle flap for bone reconstruction in adults was conducted on January 31, 2023. Flap failure and postoperative complications were synthesized with a proportional meta-analysis. Results: Forty articles describing bony reconstruction in the head and neck, upper limb, and lower limb areas were selected. Indications ranged from bony nonunion and bone defects to avascular bone necrosis. Multiple flaps were raised as either pure periosteal, cortico-periosteal, cortico-cancellous-periosteal, or cortico-chondro-periosteal. A minority of composite flaps were reported. Overall failure rate was 1% [95% confidence interval (CI), 0.00-0.08] in head & neck applications, 4% in the lower limb (95% CI, 0.00-0.16), 2% in the upper limb (95% CI, 0.00-0.06), and 1% in articles analyzing various locations simultaneously (95% CI, 0.00-0.04). Overall donor site complication rate was 4% (95% CI, 0.01-0.06). Major reported complications were: femoral fractures (n = 3), superficial femoral artery injury (n = 1), medial collateral ligament injury (n = 1), and septic shock due to pace-maker colonization (n = 1). Conclusion: The medial femoral condyle flap is a versatile option for bone reconstruction with high success rates and low donor site morbidity.

Comparisons of the morbidities of a double gastrocnemius flap and a medial gastrocnemius flap in the orthoplastic reconstruction around the knee.

BACKGROUND: The pedicled gastrocnemius flap is commonly used to treat lower limb defects. Either the medial, lateral, or both heads can be used. When extended soft tissue defects are present, a double gastrocnemius (DG) flap may be used. However, no data of the additional donor site morbidity compared to a medial gastrocnemius (MG) flap are available. The aim of this study was to compare the donor site morbidity of a DG with that of a MG. METHODS: Patients with a soft tissue defect around the knee, treated with a gastrocnemius flap between 2018 and 2021 at the University Hospital of Lausanne and Bari, with a minimum follow-up of 12 months, were included. According to the size and the position of the defect, it was decided whether one (10 patients) or two (9 patients) heads of the gastrocnemius were necessary for the coverage. The mean age was 61 years (range 42-82) in DG, and 63 years (range 45-78) in MG. The average defect size was 89.8 cm2 in the DG group and 53.4 cm2 in the MG group. The etiologies were trauma (n = 10), infection (n = 7) and sarcoma (n = 2). A medial approach or a posterior midline approach was used for the harvesting of the gastrocnemius muscle. Once the flap was harvested, it was rotated and transposed anteriorly over the defect, either through a subcutaneous tunnel or by dividing the intervening skin bridge, depending on the soft tissue defect. A split-thickness skin graft was used to close the skin over the remaining exposed muscle flap. The active range of motion of the ankle and knee joints was measured. Muscle strength was assessed with a hand-held dynamometer and by the ability to stand on tiptoe. Physical function was evaluated through the Lower Extremity Functional Scale (LEFS). RESULTS: The two groups were homogeneous, with no significant difference in age, sex, and BMI. All flaps survived in both groups. Both groups showed lower values in strength and range of motion of the operated leg, when compared to contralateral side. In plantar flexion, this accounted for a reduction in MG by 3.8 ± 1.0 kg of strength and 8 ± 3° of ROM, and in DG by 4.7 ± 1.7 kg and 16 ± 4°, respectively. For knee flexion, the reduction in MG was 4.4 ± 0.6 kg and 16 ± 7°, while in DG 5.6 ± 1.0 kg and 28 ± 6°. In the MG group, 60% were able to stand on the tiptoe of the operated leg, as opposed to 0% in DG. The average LEFS score in DG was lower by 10.9 points (p < .05). Questions concerning running and jumping had a lower score in DG (p < .01). CONCLUSIONS: The harvesting of both gastrocnemii led to significant additional donor site morbidity compared to the harvesting of the medial gastrocnemius alone. However, the additional morbidity did not have an impact on activities of daily living and walking, even though it limited the ability to perform more demanding tasks such as running and jumping. Therefore, based on our study, the choice of a DG flap should be critically assessed in younger, more demanding patients.

Oncoplastic reduction mammoplasty: Systematic review and proportional meta-analysis of surgical outcomes.

BACKGROUND: Breast-conserving surgery is the standard of care for early-stage breast cancer but can often result in unsatisfactory cosmetic outcomes. Oncoplastic surgery aims to address these issues by combining local excision with plastic surgery techniques to improve oncologic and esthetic outcomes. By incorporating breast reduction techniques into cancer surgery, wider margins of excision can be achieved, leading to enhanced oncological safety and reduced recurrence rates without causing significant asymmetry. This systematic review and meta-analysis aims to provide an updated understanding of the surgical outcomes associated with oncoplastic reduction mammoplasty. METHODS: A systematic review of the literature was conducted according to PRISMA guidelines. Articles reporting post-operative outcomes following the oncoplastic reduction mammoplasty were included. A proportional meta-analysis of post-operative complications was performed to obtain their proportions and 95% Confidence Intervals (CIs). RESULTS: Eighteen studies met the inclusion criteria, representing a total of 2711 oncoplastic reduction mammoplasty procedures in 2680 patients. The overall complication rate was 20% (95% CI: 15-25%). The positive margin rate following oncoplastic reduction mammoplasty was 11% (95% CI: 6-17%). The re-excision rate was 6% (95% CI: 3-12%). The completion mastectomy rate was 3% (95% CI: 2-6%). CONCLUSIONS: Oncoplastic reduction mammoplasty is a safe and effective alternative to mastectomy and traditional breast-conserving surgery in the treatment of early-stage breast cancers.

Incidence Trends of Melanoma of the Lower Limbs and Hips in the United States: A Surveillance, Epidemiology, and End Results Analysis 2000-2019.

BACKGROUND/AIM: No specific studies on the changes in the incidence of melanoma in the lower limbs and hips have been performed. This article aimed to examine trends in incidence rates of melanoma of the lower extremities in the U.S. PATIENTS AND METHODS: Data from the SEER program provided by the National Cancer Institute were used to examine trends in melanoma incidence from 2000 to 2019. Data analysis was performed from October to December 2022. RESULTS: A total of 192,327 cases of melanoma of the lower limbs and hips were diagnosed from 2000 to 2019 and included in our study. The incidence rate increased from 9.78 to 13.65 cases per 100,000 person-year and by an average annual percent change (AAPC) of 2% (95%CI=1.4-2.9%). The incidence increased by an AAPC of 2.1% in men and 1.7% in women. The incidence among people under 50 remained stable but increased among those over 50 years. Localized stage disease was the only stage where a continuously increasing incidence was observed, with an AAPC of 1.7% (95%CI=0.9-2.5%). Lentiginous melanoma showed the highest incidence trend rate with an AAPC of 2.3% (95%CI=1.0-3.5%). CONCLUSION: The incidence rate of melanoma in the lower limbs and hips increased between 2000 and 2019, with a higher incidence in men, reversing the previously described trend of higher incidence among women. However, incidence among people under 50 remained stable, suggesting the efficacy of prevention campaigns in this population.

Case Report: Right atrial mass arising from the Eustachian valve.

A mass in the right atrium (RA) is an unusual finding that warrants further investigation. We report the case of a 72-year-old male patient who underwent a Bentall operation with a biological composite graft and closure of patent foramen ovale 18 months prior to his presentation with an incidental new RA mass during follow-up echocardiography. Transesophageal echocardiography and thoracic CT angiography confirmed a right atrial mass attached to the Eustachian valve and additionally revealed a non-occlusive pulmonary embolism in the inferior lobar artery of the left lung. Despite 2 months of anticoagulation treatment, the size of the mass did not decrease. Further MRI imaging showed a central mass enhancement which raised concerns about a tumoral lesion. Following a discussion with the local Heart Team, management with surgical treatment was decided. The intraoperative findings revealed a 2.5 cm × 2.1 cm mass arising from the Eustachian valve and a non-diagnosed Chiari network in the RA. Both were resected and sent for a frozen section procedure which excluded a malignancy. The final histopathological analysis described fibrotic tissues compatible with an organized thrombus. The patient was discharged on postoperative day 7 without any complications. Although imaging studies are useful for the initial and differential diagnosis of RA masses, it is not always possible to get the final diagnosis without surgery. In case of a suspicion of a potentially malignant pathology, surgical exploration and resection are necessary.

Reverse Abdominoplasty in a Patient Presenting with Subcostal Nephrectomy Scar and Transverse Muscle Incisional Hernia.

Abdominoplasty and its different approaches have been widely described to improve abdominal wall contour. However, the role of reverse abdominoplasty, a less commonly performed technique, and its indications are not fully understood. Recent advances in the understanding of the vascular supply to the anterior abdominal wall have made this technique more popular, but there is still limited information available in the literature. In this report, we present the case of a 52-year-old woman who underwent a reverse abdominoplasty using an existing subcostal scar from a previous nephrectomy. No surgical complications were observed, and the patient achieved both aesthetic and functional improvement after 6 months of follow-up. Reverse abdominoplasty can be a reliable option for maintaining adequate blood supply and achieving a satisfactory cosmetic result in cases where there is a pre-existing subcostal scar.

Melanoma of the Lower Limbs and Hips: A Surveillance, Epidemiology, and End Results Analysis of Epidemiology and Survival 2000-2019.

BACKGROUND/AIM: Melanoma, an aggressive skin cancer, poses a significant threat to patients' lives, with lower limbs and hips being among the most affected regions. Epidemiology and survival outcomes of patients with melanoma in the lower extremities were investigated and compared to other sites to better understand tumoral behavior and identify predictors of decreased survival. PATIENTS AND METHODS: The Surveillance, Epidemiology, and End Results (SEER) database was used to search for all skin melanoma cases between 2000 and 2019. Demographic, pathological, and therapeutic factors were compared between affected regions. Overall and disease specific survival were calculated and compared among subgroups. A multivariable analysis was conducted to identify independent prognostic factors. RESULTS: A total of 50,109 patients were diagnosed with melanoma in lower limbs and hips, while 224,121 patients had melanomas in other areas. More women (70.8%) and younger people (mean 55.2 years, SD 16.5) were affected with lower extremities melanoma, with better survival rates than other skin regions. Factors associated with better survival included female sex, younger age, horizontal growth pattern melanomas, and surgery with <1 cm margins. CONCLUSION: Melanoma affecting lower extremities is commonly diagnosed in young females. Prognosis depends on age, stage at diagnosis, and histologic subtype, but remains better compared to other locations.

Inferior gluteal artery perforator (IGAP) flap in autologous breast reconstruction: A proportional meta-analysis of surgical outcomes.

BACKGROUND: The inferior gluteal artery perforator (IGAP) flap is an alternative technique for autologous breast reconstruction. In contrast to other commonly used techniques, there is a paucity of literature on the safety and efficacy of the IGAP flap. The aim of this study was to perform a systematic literature review and meta-analysis of postoperative outcomes and complications associated with the IGAP in autologous breast reconstructions to validate its safety. METHODS: A systematic review of literature was performed following PRISMA guidelines. Articles reporting post-operative outcomes of IGAP flaps in autologous breast reconstruction were included. A proportional meta-analysis of post-operative complications was performed to obtain their proportions with 95% confidence intervals (CIs). RESULTS: Seven studies met the inclusion criteria, which represented a total of 239 IGAP flaps in 181 patients The total flap loss rate was 3% (95% CI 0-8%), partial flap loss rate was 2% (95% CI 0-4%), haematoma rate was 3% (95% CI 0-7%), overall donor-site complication rate was 15% (95% CI 5-28%), overall recipient-site complication rate was 24% (95% CI 15-34%), and the overall complication rate was 40% (95% CI 23-58%). CONCLUSIONS: This meta-analysis provides comprehensive knowledge on the safety and efficacy of the IGAP flap in autologous breast reconstruction. It evidences the IGAP flap in autologous breast reconstruction's overall safety and validates its role as an effective option in breast reconstruction.

Cutaneous Melanoma of the Lip: A SEER Analysis of Epidemiology and Survival Outcomes With Focus on Surgery and Other Treatment Options.

BACKGROUND/AIM: Cutaneous melanoma of the lip (LM) is a rare malignancy with a low overall survival (OS). Few studies exist in the literature to aid its diagnosis and treatment. The purpose of this study was to assess the different treatment modalities by collecting cases from a single database and to provide current information on the epidemiologic characteristics of cutaneous lip melanoma. PATIENTS AND METHODS: The SEER database was searched for demographic, clinical-pathological, and therapeutic characteristics. The Kaplan-Meier model was used to analyze the overall survival (OS) of the study population, and survival curves were modelled. Univariable analysis between subgroups was carried out using the log-rank test. Surgery was further assessed with a multivariable cox regression, where the surgical procedure was adjusted for Breslow thickness. RESULTS: Patients aged 62.4 years on average, and 62.7% of them were males. A total of 386 melanomas of the cutaneous lip were identified. Mean OS was 155.1 months, median OS was 187 months, and 67.4% had localized disease. CONCLUSION: LM has a poor prognosis with a 5-year OS of 75.2%. Surgery remains the mainstay of treatment, with less invasive surgical approaches yielding a comparable overall survival to surgery with greater margins.

Spiradenocarcinoma: SEER Study of Epidemiology, Survival, and Treatment Options.

(1) Background: Spiradenocarcinoma is an extremely rare malignant adnexal tumor and there are only few studies on survival outcomes. Our aim was to perform an analysis of the demographic and pathological characteristics, treatment patterns, and survival outcomes of patients affected by spiradenocarcinoma. (2) Methods: The Surveillance, Epidemiology, and End Results program database of the National Cancer Institute was searched for all cases of spiradenocarcinoma diagnosed between 2000 and 2019. This database is considered representative of the US population. Demographic, pathological, and treatment variables were retrieved. Overall and disease-specific survival were computed according to the different variables. (3) Results: 90 cases of spiradenocarcinoma (47 females, 43 males) were identified. Mean age at diagnosis was 62.8 years. Regional and distant disease at diagnosis were rare, occurring in 2.2% and 3.3% of cases, respectively. Surgery alone was the most frequent treatment (87.8%), followed by a combination of surgery and radiotherapy (3.3%) and radiation therapy only (1.1%). Five-year overall survival was 76.2% and five-year disease-specific survival was 95.7%. (4) Conclusions: Spiradenocarcinoma equally affects males and females. Regional and distant invasion rates are low. Disease-specific mortality is low and is probably overestimated in the literature. Surgical excision remains the main form of treatment.

Impact of etiology leading to abdominoperineal resection with anterolateral thigh flap reconstruction: A retrospective cohort study.

BACKGROUND: Large and deep perineal defects following abdominal perineal resection (APR) are a challenge for reconstructive surgeons. Even if generally performed for oncological reasons, APR can be indicated as well in extended infection-related debridement for Hidradenitis suppurativa, Fournier's gangrene, or Crohn's disease. We aimed to compare the outcomes of two groups of patients with different indications for APR (infectious vs. oncological) after pedicled anterolateral thigh (ALT) flap coverage RESULTS: Forty-four consecutive pedicled ALT flap used for coverage after APR in 40 patients were analyzed. 26 patients (65%) underwent APR for oncological reasons and 14 patients (35%) for infectious reasons. The overall postoperative complications rate was significantly higher for infectious cases (76.5% vs. 40.7%, p = 0.0304). Major complications occurred in 52.9% of infectious cases versus 11.1% of oncological cases (p = 0.0045). Obesity and infectious etiology were independent risk factors for overall and major complications, respectively. CONCLUSION: Patients undergoing APR for acute or chronic infections had significantly more overall and major complications than patients having oncological APR. Modified care might be considered, especially in obese patients, in terms of surgical debridement, antibiotic treatment modalities, and postoperative management.

Merkel Cell Carcinoma of the External Ear: Population-Based Analysis and Survival Outcomes.

(1) Background: Due to its highly aggressive behavior, the ability to identify and manage Merkel Cell Carcinoma (MCC) with a full understanding of its characteristics is essential. Because the external ear is an exposed area, resection can have dramatic consequences on patient's self-image, which is why it is fundamental to detect MCC, typically found on UV-exposed regions such as the ears, at an early stage. (2) Methods: The Surveillance, Epidemiology, and End Results (SEER) database was searched for all external ear MCC between 2000 and 2019. A descriptive analysis based on frequencies was made to describe the demography of pathophysiologic features linked to MCC. Overall survival (OS) was studied and compared between variables with a log rank test. A multivariable Cox regression analysis was then computed to identify independent prognostic factors. (3) Results: A total of 210 patients (160 men) were identified with a median age of 80 years. The median OS was 47 months. Factors associated with lower OS included an age of over 80 years, the male gender, a tumor size of >5 cm, and metastatic disease. Gross (<1 cm) and wide (>1 cm) surgery excision margins were the surgery types with the best OS. (4) Conclusions: MCC of the external ear is diagnosed mostly in old men. Among the 182 patients who received a surgical procedure, gross and wide excision without radiotherapy were associated with the best OS.

Melanoma of the Upper Limb and Shoulder: A Surveillance, Epidemiology, and End Results Analysis of Epidemiology and Survival 2000-2019.

(1) Background: Melanoma is the most common life-threatening cancer among skin cancers. Almost all locations of the skin can be affected by melanoma, and the upper limbs are one of the most frequent locations. We aimed to study the epidemiology and survival outcomes of patients with melanoma localized in the upper extremities compared with other sites. (2) Methods: The National Cancer Institute (NCI) Surveillance, Epidemiology, and End Results (SEER) database is considered the most representative of the U.S. population; we extracted melanoma cases diagnosed between 2000 and 2019. Several characteristics, including demographical, pathological, and therapeutic, were recorded, and upper extremity melanomas and melanomas from other areas were compared. Overall survival was assessed, and the groups were compared. (3) Results: 69,436 patients had melanoma in the upper limbs and shoulders and 204,794 in other body parts. Overall, 35,267 patients with upper extremity melanoma were males, 34,169 were females, and the mean age was 60. For the rest of the body, there were 118,654 males and 86,140 females, with a mean age of 59. Surgery alone was the most commonly used treatment, while radiation therapy was the least used for all sites. Women appear to have better survival than men. Superficial spreading melanoma is the least lethal subtype, while nodular melanoma is the most dangerous. (4) Conclusion: Women under 50 are more at risk than men of the same age. The trend reverses after age 50 where men are at greater risk. In addition to gender and age, disease stage and major histologic subtypes influence survival.

Safety and Efficacy of the Superior Gluteal Artery Perforator (SGAP) Flap in Autologous Breast Reconstruction: Systematic Review and Meta-Analysis.

(1) Background: The superior gluteal artery perforator (SGAP) flap is a prominent technique for autologous breast reconstruction. Unlike other commonly used techniques, current literature on the safety and efficacy of the SGAP flap is heterogenous and limited. The aim of this article was to perform a systematic literature review and meta-analysis of postoperative outcomes and complications associated with SGAP flap autologous breast reconstructions. (2) Methods: A systematic literature search of multiple databases was performed using the PRISMA guidelines. We included articles evaluating SGAP flaps in autologous breast reconstruction. Outcomes and complications were recorded and analyzed. Proportions and their 95% confidence intervals (CIs) were calculated in a random-effects meta-analysis. (3) Results: Fourteen studies meeting inclusion criteria, representing a total of 667 SGAP flaps, were included. The total flap loss rate was 1% (95% CI 0-3%), partial flap loss rate was 1% (95% CI 0-3%), hematoma rate was 3% (95% CI 1-6%), emergent surgical re-exploration rate was 5% (95% CI 2-9%), and overall donor-site complications were 12% (95% CI 4-23%). (4) Conclusions: This systematic review and meta-analysis provide comprehensive knowledge on the efficacy and safety of the SGAP flap in autologous breast reconstruction. It demonstrates its overall safety and low complication rate, validating its important role as an effective option in breast reconstruction.

Locoregional anesthesia for post-operative pain management in microsurgical reconstruction of the lower extremities: A retrospective study.

OBJECTIVE: Opioid-based analgesia is often used in the management of postoperative pain in arthroplasty cases. This article analyses the safety of single-shot peripheral nerve block (PNB) and potential analgesic benefits in patients undergoing lower limb free flap reconstruction. METHODS: A retrospective review including all patients undergoing lower limb reconstruction with free flaps between October 2017 and April 2020 was performed. Patients were divided into two groups based on PNB utilization. The use of oral opioids, post-operative pain scores, flap-related outcomes, patient morbidity, and length of hospital stay (LOS) were compared between groups. RESULTS: Thirty-one patients who underwent lower limb reconstruction with free flaps, were finally included in the study. Preoperative PNB was performed on 14 patients, while 17 patients received general anesthesia (GA) alone. Pain at rest, measured using the visual analog scale (VAS) score, was significantly lower (2.2 ± 1.7 vs. 4.9 ± 1.7) in the PNB group on postoperative day 1 (POD). The mean [median]±SD amounts of opioids consumed in morphine milligram equivalent (MME) were significantly lower in the PNB group on both POD1 (33.5 [22.5] ± 33.9 vs. 61.6 [48.0] ± 39.0), POD2 (29.0 [15.0] ± 29.2 vs. 58.0 [52.5] ± 37.0) and cumulatively over 7 days (164.0 [197.0] ± 132.8 vs. 315.4 [225] ± 203.2). Complication rates and LOS were not statistically different between groups, although trending toward lower take-back procedures and major complications in the PNB group. CONCLUSION: Preoperative single-shot PNB significantly reduced postoperative opioid use and patient-reported pain severity and was not associated with an increase in complication rates.

Outcomes of the Composite Anterolateral Thigh Flap for Perineal Reconstruction After Postoncological Abdominoperineal Resection.

BACKGROUND: The vertical rectus abdominis flap is considered the gold standard in perineal reconstruction after oncological abdominoperineal resection; however, it has a nonnegligible donor site morbidity. The anterolateral thigh flap offers reliable soft tissue coverage. OBJECTIVE: The aim was to analyze long-term outcomes of composite anterolateral thigh-vastus lateralis flaps in oncological abdominoperineal resections. DESIGN: We conducted a retrospective cohort analysis of a prospectively maintained database. SETTINGS: This study was conducted in the Lausanne University Hospital. Annually, approximately 10 oncological abdomioperineal resections are performed. Literature reports 7% to 20% of patients undergoing abdominoperineal resection require flap reconstruction; in our institution, approximately 2 patients with large defects after abdominoperineal resections required reconstruction. PATIENTS: Twenty-nine pedicled anterolateral thigh-vastus lateralis flaps in 27 consecutive patients (mean age 63 years +/-11.2, 23 with radiochemotherapy) after abdominoperineal resection to cover large defects (median 190 cm2, 48-600 cm2) were analyzed. INTERVENTION: Pedicled composite anterolateral thigh-vastus lateralis flaps were performed after oncological abdominoperineal resection. MAIN OUTCOME MEASURES: Descriptive statistical analysis was conducted. Short- and long-term outcomes were analyzed, univariate and multivariate analyses were performed. Median follow-up was 16 months (12-48 months). RESULTS: Flap-related postoperative complications occurred in 16 flaps; flap-survival was 100%. Multivariate logistic analysis identified initial defect size as predictive for complications. Patients with larger defects (≥ 190 cm2) had higher complication rates (p = 0.006). Long-term analysis revealed 3 chronic fistulae, 2 tumor recurrences, 1 flap dysesthesia, and one perineal acne inversa. LIMITATIONS: Limitations include retrospective analysis, selection bias, and lacking a control group. Sample size limits statistical power. CONCLUSIONS: The pedicled anterolateral thigh-vastus lateralis flap offers reliable, stable tissue with low morbidity and good long-term outcomes. Complications compared favorably with current literature describing perineal reconstructions with rectus abdominis flaps. The composite anterolateral thigh flap is a valid alternative without the setback of abdominal donor site morbidity.

El colgajo anterolateral del muslo ofrece una cobertura confiable de los tejidos blandos.OBJETIVO:El objetivo fue analizar los resultados a largo plazo de los colgajos compuestos anterolaterales del muslo - vasto lateral - en resecciones abdominoperineales oncológicas.DISEÑO:Realizamos un análisis, retrospectivo, de tipo cohorte, de una base de datos mantenida prospectivamente.AJUSTES:Este estudio fue realizado en el hospital universitario de Lausanne. Anualmente se realizan aproximadamente 10 resecciones abdominoperineales oncológicas. La literatura reporta que entre el 7 y el 20% de los pacientes que se someten a una resección abdominoperineal requieren de reconstrucción con colgajo; en nuestra institución, aproximadamente 2 pacientes con grandes defectos tras la resección abdominoperineal requirieron reconstrucción.PACIENTES:Fueron analizados veintinueve colgajos pediculados anterolaterales de muslo - vasto lateral - en 27 pacientes consecutivos (edad media 63 años +/- 11,2, 23 con radio quimioterapia) después de la resección abdominoperineal para cubrir defectos grandes (mediana 190 cm2, 48-600 cm2).INTERVENCIÓN:Tras la resección abdominoperineal oncológica se realizaron colgajos pediculados compuestos anterolaterales de muslo - vasto lateral.PRINCIPALES MEDIDAS DE RESULTADO:Fue realizado un análisis estadístico descriptivo. Fueron analizados los resultados a corto y largo plazo - fueron realizados así mismo análisis uni y multivariados. La mediana de seguimiento fue de 16 meses (12-48 meses).RESULTADOS:Complicaciones postoperatorias relacionadas con el colgajo ocurrieron en 16 colgajos, la supervivencia del colgajo fue del 100%. El análisis logístico multivariado identificó al tamaño del defecto inicial como predictor de complicaciones. Aquellos pacientes con defectos más grandes (≥190 cm2) tuvieron mayores tasas de complicaciones (p = 0,006). El análisis a largo plazo reveló tres fístulas crónicas, dos recidivas tumorales, una disestesia de colgajo y un acné perineal inverso.LIMITACIONES:Las limitaciones incluyen análisis retrospectivo, sesgo de selección y falta de grupo de control. El tamaño de la muestra limita el poder estadístico.CONCLUSIONES:El colgajo pediculado anterolateral de muslo - vasto lateral - ofrece tejido confiable y estable con baja morbilidad y buenos resultados a largo plazo. Los resultados de las complicaciones se mostraron favorables con respecto a la literatura actual que describe reconstrucciones perineales con colgajos de recto abdominal. El colgajo compuesto anterolateral de muslo es una alternativa válida sin el revés de la morbilidad del sitio donante abdominal. Consulte Video Resumen en http://links.lww.com/DCR/B757.

Long-term evaluation of Nipple-Areolar complex changes in inferior versus superomedial pedicle reduction mammoplasty: A comparative study.

BACKGROUND: In breast reduction, traditionally the inferior pedicle (IFP) technique is considered the most performed by plastic surgeons. A growing interest for the superomedial pedicle (SMP) mammoplasty technique has been documented in literature and clinical practice. Sensory recovery of the nipple-areolar complex (NAC), final areolar shape and scarring may also have a significant impact on patient satisfaction. OBJECTIVE: This study represents a retrospective multimodal analysis comparing NAC sensation and appearance outcomes in IFP and SMP wise pattern breast reductions with 2-year follow-up. METHODS: From 2013 to 2017, all performed reduction mammoplasty were included and divided in two groups (IFP or SMP technique). Testing included pressure perception (Semmes-Weinstein monofilaments), NAC measurement (diameters ratio and circumference) and circumareolar scar hypertrophy assessment. Measurements were repeated at 2 weeks, 6 and 24 months postoperatively. RESULTS: amongst the 73 patients, 42 (58%) had SMP technique and 31 (42%) had IFP technique. Values at 6-months showed better sensory return in the SMP (p < 0.01**). NAC enlargement, showed no difference between groups. However, there was a statistically significant increase in both the SMP (p < 0.001***) and the IFP (p < 0.01**) groups when comparing the 2-week and 24-month follow-up visits measured ratios confirming a more oval appearance over time with both techniques. Scar hypertrophy showed statistically significant reduction in both the SMP (p < 0.001***) and the IFP (p < 0.01**) groups over time. CONCLUSION: This 2-year follow-up study showed little difference in outcomes between the two techniques, but some advantages in NAC sensory recovery with the SMP.
