Acromiothoracic Venous Supercharge for Abdominal-Based Free Flaps in Breast and Chest Wall Reconstruction.

BACKGROUND: Supercharging the venous drainage of free abdominal flaps in breast reconstruction has been well described in the literature, with diverse options used to augment venous drainage. In this study, we present our experience in using the acromiothoracic vein (ATV)/thoracoacromial vein (TAV) as a secondary recipient vein for the superficial inferior epigastric vein (SIEV) of free, muscle-sparing transverse rectus abdominis myocutaneous flaps in breast and chest wall reconstruction. PATIENTS AND METHODS: We retrospectively reviewed 523 free, muscle-sparing transverse rectus abdominis myocutaneous flaps the senior author (H.H.K.) performed between 2009 and 2022 for breast and chest wall reconstruction; 46 cases required venous super drainage. Seventeen patients had ipsilateral SIEV anastomosed into the second internal mammary vein, 5 had ipsilateral SIEV anastomosed into flap second deep inferior epigastric vein, and 24 required the use of the (ATV)/(TAV), which will be the focus of this study. RESULTS: The study included 24 female (20 breast and 4 chest wall reconstruction) patients ranging in ages between 39 and 72 years. They had a median follow-up of 26 months. Combined muscle splitting and cutting techniques were used to expose the ATV/TAV. Increase in operative time ranged between 10 and 20 minutes (median, 12 minutes). Vein coupler sizes were 1.5 to 3 mm. The mean weight of the flap was 740 g (range, 460-1300 g). There was 1 flap failure (salvage with latissimus dorsi flap performed), whereas 23 flaps wholly survived. CONCLUSIONS: The ATV/TAV is a suitable recipient for venous supercharging free flaps used to reconstruct breast and chest wall defects.

Mastopexy: with or without Acellular Dermal Matrix?

In the years after unilateral breast reconstruction, the reconstructed breast resists ptosis more than natural breast tissue in the native contralateral breast. As acellular dermal matrix (ADM) becomes fully incorporated into the recipient's anatomy, thus reinforcing the inferior pole of the uplifted breast, we combined our mastopexy cases with ADM in an attempt to reduce the rate of recurrent ptosis. Method: This was a prospective randomized analysis of a cohort of 24 patients, divided into two groups (A and B); all underwent primary unilateral mastopexy to correct grade III breast ptosis. Our patients had previously undergone contralateral skin sparing mastectomy with immediate breast reconstruction, for invasive breast cancer or ductal carcinoma in situ that originally was symmetrical to their native breast. The symmetrization mastopexy in half of our patients was carried out with the addition of an ADM sling to the inferior pole of the breast, to act as an internal, subcutaneous supportive "bra" (A). The other half of patients received a standard symmetrization mastopexy, without the addition of an ADM support (B). Patients were followed up for 36 months. Results: The difference between control arm and study groups revealed a statistical difference (P < 0.05), when comparing the follow-up period. From the sixth postoperative month onward, the measurements for group A revealed a statistically significant difference (P < 0.05) when compared with group B. Conclusion: The additional ADM sling acts as an added layer of support, thus delaying reoccurrence of ptosis following mastopexy.

Extended Scalp Flaps for Extensive Soft Tissue Scalp Defects as a Day Surgery Procedure Under Local Anesthetic: A Single Centre Experience.

Background Cutaneous malignancies are on the rise, associated with an increased number in scalp cancers that require wide local excision (WLE) to ensure clearance; the inelastic nature of the scalp poses a particular challenge when dealing with such large defects. Case presentation A series of 68 cases with large scalp defects following WLE for the clearance of squamous cell carcinoma, atypical fibroxanthoma, dermatofibrosarcoma protuberans, and melanoma skin cancers are presented. These cases were treated in one center under local anesthesia and underwent extended scalp flaps to close the resulting defect primarily without the use of skin grafts for the flap donor site on the scalp. Conclusion Extended scalp flap is a safe and reproducible solution for extensive scalp defects, which results in quicker wound healing with cosmetically superior results, and can be performed safely and comfortably under local anesthesia in the day case setting.

Staging computerized tomography before delayed breast reconstruction could alter the management plan.

BACKGROUND: Delayed breast reconstruction (DBR) comprises a significant proportion of breast reconstruction practice post completion of breast cancer treatment. The tumour's biology, staging, time constraints, ongoing treatment, and patient and surgeon's preference influence the decision to pursue DBR. There are no guidelines for assessing the oncological status before DBR in otherwise asymptomatic patients, particularly in those with a higher risk of recurrence. The purpose of this study was to identify the cohort of patients who could potentially benefit from staging CT scan before DBR regardless of the reconstructive modality and its impact on the overall management. MATERIAL AND METHODS: A retrospective review on 207 consecutive patients, who underwent staging CT scan before DBR in the period between 2009 and 2019 was performed. The CT scan findings were correlated with the breast prognostication scoring model (Nottingham Prognostic Index [NPI]) as an indicator factor for staging reasons. RESULTS: Incidental findings were reported in 34% (71/207) of the reviewed CT scans (incidentaloma group). There was no statistical significance in the NPI scores between non incidentaloma and incidentaloma groups. However, 5.7% (12/207) had their DBR procedure cancelled or the surgical plan altered. CONCLUSION: The patients with moderate to poor prognosis (NPI score 3.4 and above) could benefit from CT staging scan before DBR. This scan could detect adverse prognostic features precluding major surgery, which saves patients from unnecessary surgical risks and discomfort, and direct them towards the relevant management pathway.

Antia-Buch versus Franssen-Frechner Technique.

We performed a retrospective study comparing 2 patient groups. Each cohort included 22 cases of skin cancer of the external ear. Each patient required resection of the affected part of the external ear, followed by flap reconstruction. METHODS: The patients in Cohort A underwent external ear reconstruction with a classic Antia-Buch flap, as described by Antia and Buch in 1967: The defect was closed by mobilizing an advancement flap from the root of the helix (upper ear), which was closed in a V-Y fashion, after a rim of healthy scaphal cartilage was resected to allow approximation of the skin. The patients in Cohort B underwent external ear reconstruction with a modified Antia-Buch flap, as presented by Franssen and Frechner in 2010. Here, a wedge of skin was removed from the ear lobe (lower ear), to allow mobilization of an advancement flap from the caudal end of the ear, to close the defect. RESULTS: Both techniques allowed tension-free closure. Cohort B, however, required less dissection of the ear. The entire cephalic ear remained unaffected and no scaphal cartilage was sacrificed, thus preserving ear width, with scars that were overall less visible. Also, the loss in ear height associated with Cohort B was easily symmetrized by contralateral ear lobe reduction. CONCLUSIONS: Cohort B achieved closure with less ear dissection, achieving excellent morphological outcomes. The patients in Cohort B had superior levels of satisfaction with scars and ear symmetry than those in Cohort A.

Preoperative Long-term Therapeutic Subcutaneous Heparin Administration into Abdomen: Possible Cause for Nonobstructive Microvascular Flap Failure.

The anterioabdominal wall is the most common site for low molecular weight heparin administration for anticoagulation, either for prophylactic or for therapeutic indications. Occasionally, this could be associated with damage of the abdominal pannus microvasculature, which could possibly jeopardize the reliability of free abdominal flaps as deep inferior epigastric perforator and muscle sparing transverse rectus abdominis muscle, especially with therapeutic anticoagulation therapy. These flaps are reliant on a highly intricate complex vascular anatomy and perforasomes for their adequate perfusion and survival. The authors report a case of nonobstructive microvascular failure of a free muscle sparing transverse rectus abdominis muscle utilized for soft tissue coverage following resection of a chest wall breast cancer recurrence on a background of portacath-induced deep venous thrombosis of the axillary and subclavian vein whilst on chemotherapy. History of long-term therapeutic low molecular weight heparin administration in the abdomen resulted in microangiopathic densities evident on computerized tomography scan with subsequent flap failure due to possible jeopardization of the flap microvasculature and perfusion. Following exclusion of common local and systemic factors that can cause vascular compromise, a debridement and salvage re-reconstruction procedure utilizing a contralateral free latissimus dorsi flap was performed. Reconstructive surgeons should be cautious when planning to utilize free abdominal-based flaps on the background of long-term therapeutic low molecular weight heparin administration in the abdomen and may possibly explore other alternative options of using non-abdominal free flaps from the reconstructive armamentarium within this unique context.

Distally-based Peroneus Brevis Turnover Muscle Flap in the Reconstruction of Soft Tissue Defects.

Reconstruction of the distal 3rd of the lower leg requires either local or free flap coverage if tendons or bones are exposed. The distally based, pedicled peroneus brevis (PB) flap has been shown to be a valid option in the management of distal 3rd lower limb injuries. Herein, we present 21 cases treated with distally-based PB muscle flaps between May 2017 and September 2019. The defect location varied, and included defects over the lateral and medial malleolar areas, distal tibia (middle and distal 3rd junction, and the distal 3rd), and Achilles tendon area. METHODS: The PB was dissected from the lateral fibula and intermuscular septa in a cephalic to caudal direction, to a point no lower than 7 cm proximal to the lateral malleolus tip. This preserved most distal vascular perforators to the muscle, and afforded sufficient mobilization to allow successful turn-over of the muscle, with transposition into the defect within 30 minutes of tourniquet time. A meshed skin graft completed the intervention. RESULTS: The metalwork was removed in all chronic cases (10/21), as bone union had occurred. All flaps survived completely. One patient partially lost the skin graft; the wound was healed by secondary intention. No major complications occurred and no significant patient discomfort was noted. All wounds healed completely by 9 weeks of follow-up. CONCLUSION: The PB turnover muscle flap is a versatile flap, ideally suited to manage up to moderately sized defects of the distal 3rd of the lower leg, with negligible postoperative morbidity.

Pedicled local flaps: a reliable reconstructive tool for partial breast defects.

BACKGROUND: Breast conserving surgery (BCS) followed by radiotherapy has gained great popularity in the treatment of breast cancer over the past years. However, radiation therapy can lead to many unfavourable aesthetic outcomes including significant volume/skin deficiency, nipple areola complex distortion and skin contraction. We present our experience in using pedicled perforator flaps to tackle the resultant partial breast defects or deformities. METHODS: A retrospective data analysis study on Thirty patients with post breast conserving surgery (BCS) partial breast defects who were managed with pedicled per-forator flaps including muscle sparing latissimus dorsi muscle flap (MSLD), thoraco-dorsal artery perforator flap (TDAP) and intercostal artery perforator flap (ICAP) in the period between December 2008 and December 2018. RESULTS: Defects were in all quadrants apart from the upper inner quadrant. The reconstructive techniques included TDAP flap 6/30 (20%), MSLD flap 20/30 (66.7%), AICAP flap 4/30 (13.3%). Age ranges 22-35 (mean 29). All flaps showed complete survival, one nipple areola complex superficial epidermolysis was experienced, and one patient presented with fat necrosis. No resultant donor site morbidity apart from scar revision for excess skin at the axillary fold in one patient. The overall satisfaction reached 94% with only 8 patients who required lipofilling to maximize the cosmetic outcome. CONCLUSIONS: The availability of a range of reliable techniques including thoracodorsal/intercostal artery perforator flap (TAP/ICAP) and muscle sparing lattissimus dorsi flap (MSLD) allow optimum results to be achieved in the treatment of partial breast defects following breast conserving surgery.

Nipple-Sparing Mastectomy and Prepectoral Implant/Acellular Dermal Matrix Wrap Reconstruction in Large Ptotic Breasts.

Nipple-sparing mastectomy (NSM) with simultaneous prepectoral direct to implant reconstruction and acellular dermal matrix (ADM) is increasingly offered to patients opting for prophylactic or therapeutic mastectomies. The recent introduction of prepectoral implant/ADM in the armamentarium of breast reconstruction has proven to reduce pain and animation deformity. Despite this promising method, patients with macromastia and ptotic breasts remain a challenging group to treat. More often they would require secondary corrective procedures and can experience high failure rate and unsatisfactory outcomes. The authors present their experience in utilizing a bipedicled nipple-areola complex dermal flap through Wise pattern to achieve a successful NSM with prepectoral implant/ADM (Braxon) wrap (IBW) as a single stage in patients with large ptotic breasts. Patients seeking NSM with large ptotic breasts were included in the study in the period between 2016 and 2018. They were offered a single-stage Wise pattern NSM and immediate prepectoral IBW breast reconstruction. The technique and outcomes were recorded. Sixteen reconstructions were performed in 8 women with a median age of 32 years (range, 27-50 years) and a median body mass index of 32 kg/m2 (range, 29-39 kg/m2). The resected breasts weight ranged from 750 to 1,600 g (median, 890 g). All procedures were completed successfully with no nipple-areola complex necrosis or failure experienced during the follow-up period (range, 3-24 months) with all patients reported excellent satisfaction. The authors' results demonstrate that this technique could be safely planned for NSM in large ptotic breasts with excellent durable outcomes.

Chest Wall Reconstruction with Porcine Acellular Dermal Matrix (Strattice) and Autologous Tissue Transfer for High Risk Patients with Chest Wall Tumors.

BACKGROUND: Tenets of chest wall reconstruction for malignancy are well known; however, the insertion of synthetic prosthetic material to achieve rigid and nonrigid skeletal reconstruction could be associated with more complications including infection and extrusion especially in high risk patients. This includes fungating, infected tumors, previous radiotherapy, scars, smoking, diabetes, and morbid obesity. Bioprosthesis Acelluar Dermal Matrix Strattice would be a substitute to resist infection and provide stable coverage. METHODS: A retrospective data analysis study on 8 high-risk patients who underwent chest wall resection and reconstruction with bioprosthesis (Strattice) with/without titanium plates in the period between 2012 and 2017 was performed. Patient's demographics, risk factors, clinico-pathological, radiological, operative details, adjuvant therapy, postoperative morbidity, and follow-up data were recorded. RESULTS: Sarcoma was the pathology in 7 and recurrent breast cancer in 1 with age range from 21 to 71 years (mean, 50) and preponderance of female patients (n = 5). Defects were located anterior/anterolateral with size ranging from 270 to 1,050 cm2 (mean, 511). Reconstruction was performed using Strattice only in 4 patients, whereas in 4 it was combined with titanium plates. All patients required flap reconstruction (3 pedicled and 5 free). The follow-up ranged from 9 to 52 months (mean, 24.8). Minor complications occurred in 2 patients; however, good functional outcome was achieved in all. CONCLUSION: Strattice would act as a safe alternative modality for chest wall reconstruction to resist infection in high-risk patients with extensive defects. It should be considered as a valuable tool in the armamentarium of chest wall reconstruction.

Internal Pudendal Artery Perforator Island Flap for Management of Recurrent Benign Rectovaginal Fistula.

The management of recurrent rectovaginal fistula after obstetric injury and cryptoglandular sepsis is considered a major surgical challenge. The fistula poses a significant negative psychosocial and sexual morbidity. In addition, the poor quality of local tissues due to previous attempts at surgical repair adds to this challenge. There are few data regarding the management of persistent or recurrent fistula in the literature; however, several studies reported high failure rates after 2 or more procedures. We present 4 cases managed successfully in a multidisciplinary approach involving fistulectomy and immediate reconstruction with an internal pudendal artery perforator island flap.

Multidisciplinary Oncoplastic Approach Reduces Infection in Chest Wall Resection and Reconstruction for Malignant Chest Wall Tumors.

BACKGROUND: Management of complex thoracic defects post tumor extipiration is challenging because of the nature of pathology, the radical approach, and the insertion of prosthetic material required for biomechanical stability. Wound complications pose a significant problem that can have detrimental effect on patient outcome. The authors outline an institutional experience of a multidisciplinary thoracic oncoplastic approach to improve outcomes. METHODS: Prospectively collected data from 71 consecutive patients treated with chest wall resection and reconstruction were analyzed (2009-2015). The demographic data, comorbidities, operative details, and outcomes with special focus on wound infection were recorded. All patients were managed in a multidisciplinary approach to optimize perioperative surgical planning. RESULTS: Pathology included sarcoma (78%), locally advanced breast cancer (15%), and desmoids (6%), with age ranging from 17 to 82 years (median, 42 years) and preponderance of female patients (n = 44). Chest wall defects were located anterior and anterolateral (77.5%), posterior (8.4%), and apical axillary (10%) with skeletal defect size ranging from 56 to 600 cm(2) (mean, 154 cm(2)). Bony reconstruction was performed using polyprolene mesh, methyl methacrylate prosthesis, and titanium plates. Soft tissue reconstructions depended on size, location, and flap availability and were achieved using regional, distant, and free tissue flaps. The postoperative follow-up ranged from 5 to 70 months (median, 32 months). All flaps survived with good functional and aesthetic outcome, whereas 2 patients experienced surgical site infection (2.8%). CONCLUSIONS: Multidisciplinary thoracic oncoplastic maximizes outcome for patients with large resection of chest wall tumors with reduction in surgical site infection and wound complications particularly in association with rigid skeletal chest wall reconstruction.

Triangular lipodermal flaps in Wise pattern reduction mammoplasty (superomedial pedicle): A novel technique to reduce T-junction necrosis.

BACKGROUND: Although Wise pattern reduction mammoplasty is one of the most prevalent procedures providing satisfactory cutaneous reduction, it is at the expense of inevitable lengthier scars and wound complications, especially at the inverted T junction. OBJECTIVE: To describe a novel technique providing tension-free closure at the T junction through performing triangular lipodermal flaps. The aim is to alleviate skin tension, thus reducing skin necrosis, dehiscence and excessive scarring at the T junction. METHODS: One hundred seventy-three consecutive procedures were performed on 137 patients between 2009 and 2013. Data collected included demographics, perioperative morbidity and resected breast tissue weight. The follow-up period ranged from three to 30 months; early and late postoperative complications and patient satisfaction were recorded. RESULTS: Superficial epidermolysis without T-junction dehiscence was experienced in eight (4.6%) procedures while five (2.9%) procedures developed full-thickness wound dehiscence. Ninety-four percent of patients were highly satisfied with the outcome. CONCLUSIONS: The technique is safe, versatile and easy to execute, providing a tension-free zone and acting as internal dermal sling, thus providing better wound healing with more favourable aesthetic outcome and maintaining breast projection.

HISTORIQUE: Même si la réduction mammaire par patron de Wise est l'une des interventions les plus prévalentes pour assurer une réduction cutanée satisfaisante, elle se fait aux dépens de complications plus longues et inévitables des cicatrices et des plaies, particulièrement à la jonction en T inversée. OBJECTIF: Décrire une technique novatrice sans fermeture de tension à la jonction en T par lambeaux lipodermiques triangulaires. L'objectif consiste à soulager la tension cutanée, réduisant ainsi la nécrose cutanée, la déhiscence et la cicatrisation excessive à la jonction en T. MÉTHODOLOGIE: Entre 2009 et 2013, 173 interventions consécutives ont été exécutées auprès de 137 patients. Les données colligées incluent la démographie, la morbidité périopératoire et le poids des tissus mammaires réséqués. La période de suivi durait de trois à 30 mois. Les complications postopératoires précoces et tardives et la satisfaction des patients ont été enregistrées. RÉSULTATS: Huit interventions (4,6 %) se sont associées à une épidermolyse superficielle sans déhiscence de la jonction en T, tandis que cinq (2,9 %) ont donné lieu à une déhiscence pleine épaisseur de la plaie. Ainsi, 94 % des patients étaient pleinement satisfaits des résultats. CONCLUSIONS: La technique est sécuritaire, polyvalente et facile à exécuter, assure une zone sans tension et agit comme une attelle dermique interne, ce qui entraîne une meilleure cicatrisation de la plaie, aux résultats esthétiques plus favorables, qui maintient la projection mammaire.

The ortho-plastic approach to soft tissue management in trauma.

Fractures with associated soft tissue injuries, or those termed 'open,' are not uncommon. There has been much discussion regarding there management, with the guidance from the combined British Orthopaedic Association and British Association and Aesthetic Surgeons teams widely accepted as the gold level of therapy. We aim to discuss the current evidence about the initial management of this group of injuries, taking a journey from arrival in the accident and emergency department through to the point of definitive closure. Other modes of therapy are also reviewed.

Flap decisions and options in soft tissue coverage of the upper limb.

Soft tissue deficiency in the upper limb is a common presentation following trauma, burns infection and tumour removal. Soft tissue coverage of the upper limb is a challenging problem for reconstructive surgeons to manage. The ultimate choice of soft tissue coverage will depend on the size and site of the wound, complexity of the injury, status of surrounding tissue, exposure of the vital structures and health status of the patient. There are several local cutaneous flaps that provide adequate soft tissue coverage for small sized defects of the hand, forearm and arm. When these flaps are limited in their mobility regional flaps and free flaps can be utilised. Free tissue transfer provides vascularised soft tissue coverage in addition to the transfer of bone, nerve and tendons. Careful consideration of free flap choice, meticulous intraoperative dissection and elevation accompanied by post-operative physiotherapy are required for successful outcomes for the patient. Several free flaps are available for reconstruction in the upper limb including the groin flap, anterolateral flap, radial forearm flap, lateral arm flap and scapular flap. In this review we will provide local, regional and free flap choice options for upper limb reconstruction, highlighting the benefits and challenges of different approaches.

The development and future of reconstructive and microvascular surgery of the hand.

The hand is often thought of as a key discriminator in what makes humans human. The hand is both intricate and fascinating in its design and function, allowing humans to interact with their surroundings, and each other. Due to its use in manipulation of the person's environment, injury to the hand is common. Devastating hand injuries have a profound, physical, psychological, financial and socially crippling effect on patients. Advances in operative techniques and improvements in microscopes and instruments allowed Malt &McKhann to perform the first successful arm replantation in 1962 [1]. This was followed by a myriad of autologous free flaps of varying composition, that were discovered after the mapping of the cutaneous blood circulation by Taylor and Palmer [2] and Mathes & Nahai's classification of muscle flaps [3] providing us with countless options to harvest and transfer healthy, well vascularised tissues into areas of injury. Since the late sixties, with the emerging subspecialty of microvascular reconstruction, surgeons have had the technical ability to salvage many amputated parts, even entire limbs. The measure of functional outcomemust incorporate the evaluation and severity ofthe initial injury and the subsequent reconstructive surgeries [4].

Flap decisions and options in soft tissue coverage of the lower limb.

THE LOWER EXTREMITIES OF THE HUMAN BODY ARE MORE COMMONLY KNOWN AS THE HUMAN LEGS, INCORPORATING: the foot, the lower or anatomical leg, the thigh and the hip or gluteal region. The human lower limb plays a simpler role than that of the upper limb. Whereas the arm allows interaction of the surrounding environment, the legs' primary goals are support and to allow upright ambulation. Essentially, this means that reconstruction of the leg is less complex than that required in restoring functionality of the upper limb. In terms of reconstruction, the primary goals are based on the preservation of life and limb, and the restoration of form and function. This paper aims to review current and past thoughts on reconstruction of the lower limb, discussing in particular the options in terms of soft tissue coverage. This paper does not aim to review the emergency management of open fractures, or the therapy alternatives to chronic wounds or malignancies of the lower limb, but purely assess the requirements that should be reviewed on reconstructing a defect of the lower limb. A summary of flap options are considered, with literature support, in regard to donor and recipient region, particularly as flap coverage is regarded as the cornerstone of soft tissue coverage of the lower limb.

When are circular lesions square? A national clinical education skin lesion audit and study.

BACKGROUND: Skin cancer is the most prevalent cancer by organ type and referral accuracy is vital for diagnosis and management. The British Association of Dermatologists (BAD) and literature highlight the importance of accurate skin lesion examination, diagnosis and educationally-relevant studies. METHODS: We undertook a review of the relevant literature, a national audit of skin lesion description standards and a study of speciality training influences on these descriptions. Questionnaires (n=200), with pictures of a circular and an oval lesion, were distributed to UK dermatology/plastic surgery consultants and speciality trainees (ST), general practitioners (GP), and medical students (MS). The following variables were analysed against a pre-defined 95% inclusion accuracy standard: site, shape, size, skin/colour, and presence of associated scars. RESULTS: There were 250 lesion descriptions provided by 125 consultants, STs, GPs, and MSs. Inclusion accuracy was greatest for consultants over STs (80% vs. 68%; P<0.001), GPs (57%) and MSs (46%) (P<0.0001), for STs over GPs (P<0.010) and MSs (P<0.0001) and for GPs over MSs (P<0.010), all falling below audit standard. Size description accuracy sub-analysis according to circular/oval dimensions was as follows: consultants (94%), GPs (80%), STs (73%), MSs (37%), with the most common error implying a quadrilateral shape (66%). Addressing BAD guidelines and published requirements for more empirical performance data to improve teaching methods, we performed a national audit and studied skin lesion descriptions. To improve diagnostic and referral accuracy for patients, healthcare professionals must strive towards accuracy (a circle is not a square). CONCLUSIONS: We provide supportive evidence that increased speciality training improves this process and propose that greater focus is placed on such training early on during medical training, and maintained throughout clinical practice.
