Surgical management of locally advanced breast cancer: Recommendations of the Brazilian Society of Surgical Oncology.

The Brazilian Society of Surgical Oncology organized a group of oncological surgeons to discuss surgical aspects associated with locally advanced breast carcinoma. This article reviews the indications, different surgeries (thoracoabdominal or myocutaneous flaps), and associated complications. It discusses special conditions such as invasion of the chest wall and interscapular thoracic disarticulation. It makes recommendations based on the literature regarding clinical findings, tumor conditions, response to neoadjuvant therapy, choice of flaps in surgery, and tumor biology.

First Successful Separation of Craniopagus Twins in India-Plastic Surgical Considerations.

Separation of total vertical craniopagus with shared venous sinuses poses multiple challenges. Provision of soft-tissue cover to the exposed brains at the time of total separation is one of them, due to the large size of the defect and paucity of local tissues. Staged separation of twins is advised with partial venous and parenchymal disconnection in the first stage and total separation in the second stage. Tissue expanders are inserted in the first stage, and second stage planned to coincide with the period of adequate expansion. In the child being reported, emergency second stage was done due to the deteriorating general condition of the children. Left with inadequate expanded skin, the critical defect in a twin was managed with bilateral trapezius myocutaneous flaps. High ionotropic support of the postoperative period resulted in superficial necrosis of the flap, which was managed by debridement, allograft application and autograft later. Both twins had well-healed wounds by 3 months.

Primary vs myocutaneous flap closure of perineal defects following abdominoperineal resection for colorectal disease: a systematic review and meta-analysis.

AIM: Perineal wound complications after abdominoperineal resection (APR) have become a major clinical challenge. Myocutaneous flap closure has been proposed in place of primary closure to improve wound healing. We conducted this comprehensive meta-analysis to evaluate the current scientific evidence of primary closure vs myocutaneous flap closure of perineal defects following APR for colorectal disease. METHODS: We systematically searched the MEDLINE, Embase, PubMed, Web of Science and Cochrane Library databases to identify all relevant studies. After data extraction from the included studies, meta-analysis was performed to compare perioperative outcomes of primary closure and myocutaneous flap closure. RESULTS: Eighteen studies with a total of 17 913 patients (16 346 primary closure vs 1567 myocutaneous flap closure) were included. We found that primary closure was significantly associated with higher total perineal wound complications (P = 0.007), major perineal wound complications (P < 0.001) and perineal wound infection (P = 0.001). On the other hand, myocutaneous flap closure takes more operation time (P < 0.001) and increases the risk of perineal wound dehiscence (P = 0.01), deep surgical site infection (P < 0.001), enterocutaneous fistulas (P = 0.03) and return to the operating room (P = 0.0005). There were no significant differences between the two groups for other outcomes. CONCLUSIONS: This is the first systematic review with meta-analysis comparing primary closure with myocutaneous flap closure of perineal defects after APR for colorectal disease. Although taking more operation time and an increased risk of specific complications, the pooled results have validated the use of myocutaneous flaps for reducing total/major perineal wound complications. More investigations are needed to draw definitive conclusions on this dilemma.

Breast reconstruction for locally advanced breast cancer previously submitted to mastectomy and an ipsilateral thoracoabdominal dermofat (ITADE) flap.

Thoracoabdominal (TA) flaps are a good option for primary closure of small and medium defects after mastectomy for locally advanced breast tumours. Although they have a higher rate of necrosis than myocutaneous flaps, they can be easily performed by breast surgeons. Few studies on this procedure have been reported, and we have been unable to identify any prior publications reporting breast reconstruction with TA flaps.

Perianal mucinous adenocarcinoma: A case report.

INTRODUCTION: Perianal mucinous adenocarcinoma is a tumor that is rarely seen by colorectal or even general surgeons. CASE PRESENTATION: Here we report a case of mucinous adenocarcinoma associated with chronic anal fistula in a 43 years old male patient. He underwent laparoscopic abdominoperineal resection and coverage with myocutaneous pedicled gracilis muscle flap. DISCUSSION: Most cases are related to chronic anal pathologies, such as anal fistulae; however, further studies are needed for a causation link to be made between the two conditions. Available literature shows that the optimal treatment of perianal mucinous adenocarcinoma is radical surgical resection combined with pre- or postoperative chemoradiotherapy. CONCLUSION: This case report is to highlight the rare incidence of mucinous adenocarcinoma in the perianal region.

Bilateral rectus femoris myocutaneous flaps to salvage exposed axillo-bifemoral graft of bilateral groins.

Exposed prosthetic grafts are a challenge to vascular specialists. Groin dissections in vascular surgery can lead to local tissue breakdown, especially in patients who have multiple comorbidities and poor nutritional status. In this report, we describe a patient with exposed prosthetic bypass conduits in the groin region which was successfully covered with bilateral myocutaneous flaps. A 75-year-old Sri Lankan male with diabetes, hypertension and Parkinson's disease presented with bilateral non-healing wound and rest pain for 3 months. Since his premorbid status precluded the aortic cross-clamping and aorto-bifemoral graft, a decision was made to perform a right axillo-bifemoral bypass using a prosthetic graft. Re-operation was required for graft thrombectomy on the same day of surgery. His post-operative period was complicated with lymph leak and surgical site infection of bilateral groin wounds which ultimately led to exposed prosthetic graft which was fortunately patent. After optimizing his nutritional status and comorbidities, he underwent bilateral rectus femoris myocutaneous flaps to cover the soft-tissue defect over the exposed prosthetic grafts. His initial post-operative period was unremarkable except for a small area of skin breakdown. Myocutaneous flaps are preferred as they are more resilient to breakdown compared to facio-cutaneous flaps, especially in a patient with compromised blood supply. The type of loco-regional flap should be carefully selected in an individualized manner depending on the regional vascularity. The rectus femoris flap is a suitable option in terms of ease of surgical technique and durability. Comorbidities and local factors should be optimized prior to definitive reconstruction to maximize the chances for optimal wound healing.

The pedicled myocutaneous flap as a choice reconstructive technique for immediate adjuvant brachytherapy in sarcoma treatment.

Successful treatment of soft-tissue sarcomas is highly dependent on total tumour resection coupled with adjuvant radiation therapy to achieve local control and decrease recurrence. Reconstruction of soft-tissue defects after resection aims to cover vital structures, while providing enough stable tissue to withstand adjuvant brachytherapy treatment. In the present study, pedicled myocutaneous flaps were used as a vital adjunct in the treatment of soft-tissue sarcoma, and our experience with 2 such patients is described. The flaps served to reconstruct large three-dimensional defects while providing stable coverage over brachytherapy hardware to allow for delivery of radiation in the immediate postoperative period. Pedicled locoregional myocutaneous flaps provide a safe, easy, and reliable reconstructive technique in the treatment of soft-tissue sarcoma.

Auriculotemporal Carcinoma - A Retrospective Case Series.

Rationale: Eleven cases with auriculotemporal cancer were reviewed for prognostic analysis. Patient Concerns: Follow-up ranged from 1.2 to 12 years (median 5.01 years). Diagnosis Treatment and Outcome: Three patients with parotid gland carcinoma, out of those, two had chemoradiotherapy, died in the first 2 years of treatment. They were at stage T4 and tumour progressed with distant metastasis. Otorrhoea was the most common symptom in patients with primary temporal bone carcinoma. One patient with auricular carcinoma had a recurrence at the primary site 13 months after surgery. One patient with T1, two patients with T2 and one patient with T3 have completed a 5-year survival period. One patient with T1 and another one with T2 are still at a 2-year follow-up period with no recurrence. Take-Away Lessons: Complete resection is the treatment of choice. Post-operative radiotherapy is highly recommended. The most decisive prognostic indicator is the advanced stage. Early diagnosis has great importance.

Surgical Free Flaps and Grafts in Head and Neck Reconstruction: Principles and Postoperative Imaging.

This review article discusses the basic principles behind the use of flaps and grafts for reconstructive surgery in the head and neck, with a special emphasis on the types of commonly used free flaps, their imaging appearance as well as some frequently encountered postoperative complications. Given the ubiquity and complexity of these reconstructive techniques, it is essential that head and neck radiologists be familiar in distinguishing between the expected evolving findings, complications, and tumor recurrence.

A cost-effectiveness analysis of delayed breast reconstruction with pedicled flaps from the back.

BACKGROUND: Variability in breast reconstruction methods provides an opportunity to investigate whether a method is superior to another with regard to cost, quality, or both. We performed a cost-effectiveness analysis (CEA) study based on tertiary endpoint data from a randomized clinical trial to compare the cost-effectiveness of delayed breast reconstruction by either a latissimus dorsi flap (LD) or a thoracodorsal artery perforator flap (TAP). MATERIAL & METHODS: A total of 50 women were included for unilateral delayed breast reconstruction and were randomized to reconstruction by either the LD flap (n = 18) or the TAP flap (n = 22). The CEA was based on differences in shoulder function after the reconstruction. Direct and indirect costs relating to the two procedures were assessed by the Danish Diagnosis-Related Groups tariffs. RESULTS: Our analysis showed a significant positive effect of introducing the TAP flap on the total shoulder score with an additional cost of $2779. The incremental cost-effectiveness ratio was $4481 and based on a willingness to pay (WTP) $500, we found an estimated net benefit of $519, which was statistically significant (p = 0.0375). The cost-effectiveness acceptability curve indicated that there is a 96.3% probability for the TAP flap being cost-effective to the LD flap at a WTP threshold of $500. CONCLUSION: From a societal perspective, our cost-effective analysis demonstrated that the TAP flap is the more cost-effective method of breast reconstruction compared to the LD flap with respect to patient-reported shoulder-related disability.

Choice of Regional Flaps for Oral Cancer Defects: Relevance in Current Era.

INTRODUCTION: Microvascular free flaps (MVFF) are the current standard of care for reconstruction of oral ablative defects; however, pedicled myocutaneous flaps (PMCF) are still used widely in India. The rationale behind the preference for selecting PMCF in the present era is not well understood. The associated complications and swallowing outcomes are variable. METHODS: We retrospectively analysed the records of patients who underwent reconstructive surgery for oral cancer ablative defects over a 3-year period. RESULTS: Ninety-seven pedicled myocutaneous flaps [89 pectoralis major myocutaneous (PMMC) flaps, eight lower trapezius island myocutaneous (TMC) flaps] and 113 MVFFs were performed. The reasons for selecting PMCF were financial constraints 38.7%, MVFF salvage 22.5%, medically compromised 10.7%, vessel-depleted neck 6.4%, old age with PS2 + 5.3%, early recurrence 5.3%, borderline resectable 4.3%, palliative resection 2.1%. Overall complication rate was 20.4%. Of patients, 50.7% and 34.7% were on regular and semisolid diet, respectively; 66.6% had acceptable swallowing-related social well-being. CONCLUSION: PMCFs have an important role in developing countries with patients having financial constraints. The other potential reasons driven by patient factors were discussed. The swallowing outcomes are good, with majority of the people having socially acceptable swallowing function.

Chest wall resection and reconstruction: a case series of 20 patients in Hospital Kuala Lumpur, Malaysia.

Chest wall resection is defined as partial or full-thickness removal of the chest wall. Significant morbidity has been recorded, with documented respiratory failure as high as 27%. Medical records of all patients who had undergone chest wall resection and reconstruction were reviewed. Patients' demographics, length of surgery, reconstruction method, size of tumor and chest wall defect, histopathological result, complications, duration of post-operative antibiotics, and hospital stay were assessed. From 1 April 2017 to 30 April 2019, a total of 20 patients underwent chest wall reconstructive surgery. The median age was 57 years, with 12 females and 8 males. Fourteen patients (70%) had malignant disease and 6 patients (30%) had benign disease. Nine patients underwent rigid reconstruction (titanium mesh for sternum and titanium plates for ribs), 6 patients had non-rigid reconstruction (with polypropylene or composite mesh), and 5 patients had primary closure. Nine patients (45%) required closure with myocutaneous flap. Complications were noted in 70% of patients. Patients who underwent primary closure had minor complications. In total, 66.7% of patients who had closure with either fasciocutaneous or myocutaneous flaps had threatened flap necrosis. Two patients developed pneumonia and 3 patients (15%) had respiratory failure requiring tracheostomy and prolonged ventilation. There was 1 mortality (5%) in this series. In conclusion, chest wall resections involving large defects require prudent clinical judgment and multidisciplinary assessments in determining the choice of chest wall reconstruction to improve outcomes.

Are venous thromboembolism risk assessment tools reliable in the stratification of microvascular risk following lower extremity reconstruction?

INTRODUCTION: The incidence of flap failure is significantly higher in the lower extremity compared to free tissue transfer in the head, neck and breast. The most common cause of flap failure is venous thrombosis. The aim of this study was to assess the reliability of venous thromboembolism (VTE) risk assessment tools in this high-risk cohort and to assess the ability of such tools to identify patients at risk of developing microvascular venous thrombosis and venous thromboembolism following lower extremity free flap reconstruction. METHODS: A single centre retrospective cohort study was conducted between August 2012-August 2019. Adult patients who had undergone free tissue transfer following open lower extremity fractures were eligible for inclusion. All patients were retrospectively risk assessed using the Department of Health (DoH), Modified Caprini and Padua VTE risk assessment tools. RESULTS: Fifty-eight patients were included; all were at high risk of DVT according to the DoH (mean score ± SD, 3.7 ± 0.93), Caprini (10.2 ± 1.64) and Padua (5.4 ± 0.86) risk assessment tools. All patients received appropriate thromboprophylaxis; the incidence of symptomatic hospital acquired VTE was 3.5%. Micro-anastomotic venous thrombosis occurred in 4 patients resulting in one amputation. Partial flap necrosis occurred in 7 patients. There were no significant differences in scaled Caprini (median score, 10 vs 9, z = 1.289, p = 0.09), DoH (3 vs 3, z = 0.344, p = 0.36), and Padua (5 vs 5.5, z= -0.944, p = 0.17) scores between those with and without microvascular venous thrombosis. CONCLUSION: This data suggests that current VTE risk assessment tools do not predict risk of microvascular venous thrombosis following lower extremity reconstruction. Further prospective studies are required to optimise risk prediction models and thromboprophylaxis use in this cohort.

Sternoclavicular Joint Infections: Improved Outcomes With Myocutaneous Flaps.

Sternoclavicular joint (SCJ) infection is a rare disease and its management remains controversial. Our institution has adopted an aggressive surgical approach of radical SCJ resection combined with myocutaneous flap (MCF) closure whenever possible. We reviewed our experience with this approach in the management of this condition. From July 2004 to June 2018, 50 consecutive patients were treated surgically for SCJ infections. Patient demographics, imaging studies, microbiology, and operative variables were analyzed. All patients underwent ipsilateral SCJ resection. Wound closure was performed with primary pectoralis advancement MCF closure at the initial operation in 25 patients, delayed MCF closure following temporary wound vacuum therapy and redebridement in 19 patients, and definitive wound vacuum therapy (DWVT) in 6 patients. End points were recurrence of infection, perioperative morbidity, and mortality. Localized swelling (100%) and pain (100%) were the most common presenting symptoms. MSSA was isolated in 50% of tissue cultures. Comorbidities included tobacco smoking 52%, diabetes mellitus 50%, intravenous drug use 34%, poor dental hygiene 32%, and obesity 28%. We had no deaths within 90 days of operation. Complications; seroma in 1 patient (2%), chest wall hernia in 1 patient (2%), retained drains in 1 patient (2%), recurrent osteomyelitis infection in 3 patients (6%), and hematomas in 5 patients (10%). Patients treated with primary MCF closure at the initial operation had a 0% (0/25) rate of recurrence compared to 5.26% (1/19) in delayed MCF closure. Overall, there was only a 2.27% (1/44) recurrence of infection in primary and delayed MCF closure combined, compared to 33.33% (2/6) in patients treated with DWVT closure. SCJ infections require an aggressive approach. Wound closure with an MCF (primary or delayed) is associated with less recurrence of infections compared with DWVT closure. Radical resection of the entire SCJ with MCF (primary or delayed) should be considered the preferred management strategy in patients with SCJ infections.

Usefulness of the orbicularis oculi myocutaneous flap in periorbital reconstruction.

BACKGROUND: The esthetic and functional outcomes of periorbital defect reconstruction are very important because of the complex anatomy and specialized functions of this region. The orbicularis oculi myocutaneous (OOMC) flap is useful for the reconstruction of periorbital defects. But, according to the location and depth of the defects, the reconstruction using OMC flaps with various techniques is rare. The authors have used various kinds of OOMC flaps in various situations and we present an analysis of our experiences. METHODS: From November 2001 to July 2017, we used 36 OOMC flaps to reconstruct 30 periorbital defects in 25 patients. We analyzed the cause of the defect, its location, the type of concomitant surgery, the method of flap movement, and complications. RESULTS: Of the 30 defects, basal cell carcinoma was the most common cause, accounting for 20 cases. When the used OOMC flap was classified according to the location of the defects, the switch flap was used in nine cases among 15 defects of lower eyelid, and the V-Y advancement flap was mainly used for other parts. As surgical methods according to the depth of defect were classified, all cases involving the tarsal plate were reconstructed with a composite graft. In case of skin and muscles, they were reconstructed only with OOMC flap or with full-thickness skin graft. CONCLUSION: The OOMC flap provides good skin quality that is very similar to that of the defect tissue. Depending on the location and depth of the defect, the OOMC flap may be used properly in a variety of ways to achieve good results.

Long Term Cosmetic and Functional Results of One Stage Reconstruction for Lower Eyelid Malignant Melanoma: A Single Centre Experience of Eleven Patients.

INTRODUCTION: Eyelid malignant melanoma represents less than 1 % of all skin melanomas and approximately 1 % of all malignant neoplasms of the eyelid skin. Because of its relative rarity, there is a paucity of descriptive papers reporting only small series of reconstructed patients. The repair of eyelid defects represents a reconstructive challenge. Ideally, the reconstruction of the defect must guarantee function with tissue of the same color, texture, and thickness of that of the removed skin and at the same time avoid complications such as ectropion and lagophthalmos. MATERIALS AND METHODS: We describe a consecutive series of 11 patients affected by cutaneous melanoma of the lower lid who underwent full-thickness excision of the neoplasm and subsequent wide excision. All the patients were treated in one-stage reconstruction modality with a modified monopedicle myocutaneous flap, harvested from omolateral upper eyelid, tunneled under the lateral canthus skin and armed with a conchal auricular cartilage framework. Four patients underwent the sentinel lymph node biopsy during reconstructive procedure. No major complications were reported. In our experience, the proposed myocutaneous flap allows to obtain excellent results, both aesthetically and functionally. CONCLUSIONS: This technique has the advantage of avoiding multi-staged procedures, with respect for the oncological excision indication for head and neck melanoma, decreasing the incidence of associated major complications.

[Defect coverage using gluteal flaps]. / Defektdeckung durch Gluteuslappen.

OBJECTIVE: Gluteal skin, fasciocutaneous and myocutaneous flaps can be used to cover decubitus ulcers in the sacral and ischiocrural area. INDICATIONS: Decubitus ulcers in the sacral or ischial area that do not heal after exhausted conservative therapy. CONTRAINDICATIONS: Moribund patients who are very likely to suffer a life-threatening complication. Non-cooperative patients who cannot follow the postoperative recommendations. The presence of extensive scars after previous operations in the donor area or irradiation of the donor area which may compromise the flap perfusion. SURGICAL TECHNIQUE: A distinction is made between local skin flaps, perforator-based fasciocutaneous flaps and the myocutaneous gluteus maximus flap. By partial or complete elevation of the gluteus maximus muscle based on the superior and inferior gluteal vessels, this flap is useful for larger and deep defects in the sacral and ischial region. For more superficial defects, fasciocutaneous perforator flaps might be used. Smaller ulcers can be treated with local skin flaps. The donor site should be closed primarily. POSTOPERATIVE MANAGEMENT: Consistent, postoperative relief by prone and lateral positioning of the patient, avoiding new decubitus ulcers. Drainage for at least 5-7 days. Antibiotic therapy is indicated only with appropriate detection of pathogens and in case of persistent infection. RESULTS: With distinct anatomical and improved technical knowledge, the use of fasciocutaneous and myocutaneous flaps in the gluteal region is now an established procedure and can be used for reliable coverage of sacral and ischiocrural decubitus ulcers.

Three-Directional Reconstruction of a Massive Perineal Defect after Wide Local Excision of Extramammary Paget's Disease.

Extramammary Paget's disease (EMPD) is a rare, slow-growing intraepithelial malignancy that mainly involves the genital region, including the vulva, penis, scrotum, perianal, and periurethral areas. Although several treatment options exist, wide local excision with a safe margin is considered the treatment of choice. After resection of the lesion, it is often challenging to reconstruct the defect because defects in the perineal region require adequate volume for protection and are susceptible to infections, which is a particularly significant risk for large defects. We report a case of perivulvar EMPD that was reconstructed with three-directional local flaps after wide excision of the tumor. We covered the defect sequentially using the following 3 flaps: a gracilis myocutaneous flap from the left thigh, a bipedicled V-Y advancement flap from the lower abdomen, and an internal pudendal artery perforator-based island flap from the right buttock. To the best of our knowledge, this report is the first to describe a three-directional approach to extensive perivulvar reconstruction.

Medial and lateral canthal reconstruction with an orbicularis oculi myocutaneous island flap.

BACKGROUND: The eyelid and canthal areas are common locations for cutaneous tumors. The medial canthus includes, among many other apparatuses, the canthal tendon and lacrimal canaliculi, and its characteristic thin and supple skin is hard to mimic and restore using tissue from other regions. Accordingly, reconstruction of the canthal area can prove challenging for surgeons. Although various methods, such as skin grafts and local flaps from adjacent regions, have been utilized for reconstructive purposes, they present known disadvantages. However, we were able to successfully reconstruct both lateral and medial canthal area defects by using orbicularis oculi myocutaneous island flaps. METHODS: Our study included seven patients who underwent medial or lateral canthal region reconstruction, using orbicularis oculi myocutaneous island flaps, between 2011 and 2014, following either cutaneous tumor excision or traumatic avulsion injury. RESULTS: Five patients had basal cell carcinoma, one had squamous cell carcinoma of the eyelid, and one had sustained a traumatic avulsion injury of the eyelid and canthal area. Entire flap loss was not observed in any patient, but one-a heavy smoker-showed partial flap loss, which healed with secondary intention and yielded acceptable results. Donor site morbidity was not observed, and all patients were satisfied with their surgical outcomes. CONCLUSIONS: The canthal regions can be successfully reconstructed with orbicularis oculi myocutaneous island flaps. These flaps offer several key advantages, including similarity in texture, color, and thickness to the recipient site and a negligible incidence of donor site morbidity.

Contemporary role of pectoralis major regional flaps in head and neck surgery.

Countless disadvantages of the "old" pectoralis major have been listed while the amazing versatility of the free flap armamentarium gives the opportunity to suit the defect deriving from virtually every ablative head and neck surgery with a tailored reconstruction. Nevertheless, pectoralis major is still the "workhorse" for head and neck reconstruction in developing countries thanks to its ease of harvest, and minimal requirements in term of instrumentation. Furthermore, even in facilities with a high volume of reconstructions by free flaps, a certain number of pectoralis major flaps is still raised every year. The history, present role and current indications of the most widely head and neck reconstructive procedure ever has been reviewed.
