Evaluation of Classic and Quantitative Imaging Features in the Differentiation of Benign and Atypical Lipomatous Soft Tissue Tumors Using a Standardized Multiparametric MRI Protocol: A Prospective Single-Centre Study in 45 Patients.

BACKGROUND: Discrimination between benign and atypical lipomatous tumors (ALT) is important due to potential local complications and recurrence of ALT but can be difficult due to the often-similar imaging appearance. Using a standardized MRI protocol, this study aimed to rank established and quantitative MRI features by diagnostic value in the differentiation of benign and atypical lipomatous tumors and to develop a robust scoring system. METHODS: Patients with clinical or sonographic suspicion of a lipomatous tumor were prospectively and consecutively enrolled from 2015 to 2019 after ethic review board approval. Histology was confirmed for all ALT and 85% of the benign cases. Twenty-one demographic and morphologic and twenty-three quantitative features were extracted from a standardized MRI protocol (T1/T2-proton-density-weighting, turbo-inversion recovery magnitude, T2* multi-echo gradient-echo imaging, qDIXON-Vibe fat-quantification, T1 relaxometry, T1 mapping, diffusion-weighted and post-contrast sequences). A ranking of these features was generated through a Bayes network analysis with gain-ratio feature evaluation. RESULTS: Forty-five patients were included in the analysis (mean age, 61.2 ± 14.2 years, 27 women [60.0%]). The highest-ranked ALT predictors were septation thickness (gain ratio merit [GRM] 0.623 ± 0.025, p = 0.0055), intra- and peritumoral STIR signal discrepancy (GRM 0.458 ± 0.046, p < 0.0001), orthogonal diameter (GRM 0.554 ± 0.188, p = 0.0013), contrast enhancement (GRM 0.235 ± 0.015, p = 0.0010) and maximum diameter (GRM 0.221 ± 0.075, p = 0.0009). The quantitative features did not provide a significant discriminatory value. The highest-ranked predictors were used to generate a five-tiered score for the identification of ALTs (correct classification rate 95.7% at a cut-off of three positive items, sensitivity 100.0%, specificity 94.9%, likelihood ratio 19.5). CONCLUSIONS: Several single MRI features have a substantial diagnostic value in the identification of ALT, yet a multiparametric approach by a simple combination algorithm may support radiologists in the identification of lipomatous tumors in need for further histological assessment.

High-Voltage Injuries by Contact With Overhead Lines: Case Reports of Two Young Girls.

High-voltage burn injuries are rare in the pediatric age group, but can lead to devastating, severe sequelae. We present the cases of two young girls who suffered high-voltage burn injuries due to direct contact with overhead power lines. Both patients came from difficult psychosocial backgrounds. The injuries resulted in severe long-term consequences and functional deficits.

The questionable benefit of pectus excavatum repair on cardiopulmonary function: a prospective study.

OBJECTIVES: Since the introduction of the minimally invasive technique for repair of pectus excavatum (MIRPE), increasing numbers of patients are presenting for surgery. However, controversy remains regarding cardiopulmonary outcomes of surgical repair. Therefore, the aim of our prospective study was to investigate cardiopulmonary function, at rest and during exercise before surgery, first after MIRPE and then after pectus bar removal. METHODS: Forty-seven patients were enrolled in a prospective, open-label, single-arm, single-centre clinical trial (Impact of Surgical Treatments of Thoracic Deformation on Cardiopulmonary Function) [NCT02163265] between July 2013 and November 2019. All patients underwent a modified MIRPE technique for surgical correction of pectus excavatum (PE), called Minor Open Videoendoscopically Assisted Repair of Pectus Excavatum. The patients underwent pre- and postoperative chest X-ray, three-dimensional volume-rendering computer tomography thorax imaging, cardiopulmonary function tests at rest and during stepwise cycle spiroergometry (sitting and supine position) and Doppler echocardiography. Daily physical activity questionnaires were also completed. RESULTS: The study was completed by 19 patients (15 males, 4 females), aged 13.9-19.6 years at the time of surgery. The surgical patient follow-up was 5.7 ± 7.9 months after pectus bar removal. No significant differences in cardiopulmonary and exercise parameters were seen after placement of the intrathoracic bar, or after pectus bar removal, compared to presurgery. CONCLUSIONS: Our findings indicate that surgical correction of PE does not impair cardiopulmonary function at rest or during exercise. Therefore, no adverse effects on exercise performance should be expected from surgical treatment of PE via the modified MIRPE technique.

Impact of surgical treatment of pectus carinatum on cardiopulmonary function: a prospective study.

OBJECTIVES: The frequency of sternochondroplasty in cases of pectus carinatum (PC) has increased due to greater surgeon experience and modified surgical techniques. PC deformity does not usually cause cardiopulmonary malfunction or impairment. However, whether cardiopulmonary function changes after surgical repair remains a matter of controversy. The aim of our prospective study was to determine if surgery changes preoperative cardiopulmonary function. METHODS: Nineteen patients (16 males, 3 females) were enrolled in a prospective, open-label, single-arm, single-centre clinical trial (Impact of Surgical Treatments of Thoracic Deformation on Cardiopulmonary Function) (NCT02163265) between July 2013 and January 2017. All patients underwent PC repair via a modified Ravitch procedure and wore a lightweight, patient-controlled chest brace for 8 weeks postoperatively (the Innsbruck protocol). The average follow-up surgical examination was 8.3 months after surgery. In all enrolled patients, before surgery and not before 6 months postoperatively chest X-ray, 3-dimensional volume-rendered computed tomography thorax imaging, cardiopulmonary function tests with stepwise cycle spiroergometry (sitting and supine position) and Doppler echocardiography were performed; questionnaires about daily physical activity were also completed. RESULTS: Fourteen patients (aged 16.3 ± 2.6 years at study entry) completed the study. Changes in submaximal and peak power output were not detected during sitting, or when in the supine position. Also, no clinically relevant postoperative changes in spirometry or echocardiography were noted. CONCLUSIONS: Our findings confirm that surgical correction of PC does not impair cardiopulmonary function at rest or during physical exercise. CLINICAL REGISTRATION NUMBER: clinicaltrials.gov NCT02163265.

Follow-up Strategies for Primary Extremity Soft-tissue Sarcoma in Adults: A Systematic Review of the Published Literature.

AIM: Follow-up strategies for primary extremity soft-tissue sarcomas (eSTS) in adults were evaluated in a systematic review of the published literature. MATERIAL AND METHODS: The published literature was reviewed using PubMed. Of 136,646 studies published between 1985 and 2019, 78 original articles met the inclusion criteria. Articles were selected on the basis of the PRISMA guidelines. The selected articles were then cross-searched to identify further publications. August 1, 2019 was used as the concluding date of publication. RESULTS: A variety of follow-up schedules have been reported in recently published literature. Two official guidelines have been approved by international societies. The guidelines distinguish between high- and low-grade STS, but mention a wide range of follow-up intervals. Established tools of follow-up include computed tomograph, X-rays of the chest, and magnetic resonance imaging of the primary tumor site in addition to clinical observation and physical examination. CONCLUSION: Further research will be needed to establish evidence-based guidelines and schedules for follow-up strategies in patients with eSTS.

Aesthetic outcomes after surgical repair of pectus excavatum in females: Differences between patients and professional evaluators.

BACKGROUND: Pectus excavatum is less common in females than in males, and it often aggravates a coexistent breast asymmetry. We conducted a study comparing female patients' versus medical professionals' evaluation of pectus excavatum repair to assess differences in aesthetic outcome ratings. Moreover, we evaluated the influence of surgical correction on patients' self-perception. METHODS: Of 30 female patients who were initially screened, 18 patients (mean age, 20 years) who underwent bar removal after surgical correction of pectus excavatum deformity participated in the survey (60%). They completed a questionnaire rating their appearance before and after surgery and responded to a psychological questionnaire about the changes that they had experienced. The mean interval between pectus bar removal and evaluation was 28 months. Standardized preoperative and postoperative patient photographs were evaluated using the same questionnaire by a panel of medical professionals and students (n=24) and the results were compared. RESULTS: Patients rated their preoperative deformity as more severe than the other evaluators, revealing the significant impact of the deformity on patients' self-perception. Postoperatively, patient and professional evaluations were much better than before and were very similar. The psychological evaluation showed a clear improvement in well-being. The ratings of the medical professionals were not influenced by their degree of medical education. CONCLUSIONS: Surgical correction of pectus excavatum in female patients positively influences body perception and psychological well-being. It should therefore not be considered as a merely aesthetic correction, but as an important procedure to restore a patient's self-perception.

Cystic echinococcosis in the thigh: a case report.

Intramuscular cystic echinococcosis is a very rare occurrence. Herein we report a case of a 37-year-old patient who presented with progressive swelling of his left thigh. Ultrasound evaluation showed a multicystic, encapsulated lesion (16 × 3.5 × 8.5 cm) in the M. vastus lateralis, and serology confirmed the diagnosis of Echinococcus granulosus s.l. infection. No additional cysts were detected upon total body CT scan. The patient was treated with albendazole pre-operatively; surgical resection of the mass was then successfully performed. The patient feels well and no signs of residual infestation were seen after 2 years of follow-up.

Deformities of the Thoracic Wall: Don't Forget the Plastic Surgeon.

Surgical procedures for pectus excavatum (PE) repair, such as minimally invasive repair of pectus excavatum or similar interventions (modified open videoendoscopically assisted repair of pectus excavatum), for remodeling the anterior thoracic wall may finally not always achieve sufficiently pleasing aesthetic results. Particularly in the asymmetric and polymorphic cases, remnant deformities may still be present after any sophisticated remodeling attempt. On the other hand, some cases despite optimal surgical management develop mild recurrences with partial concavity or rib cartilage distortion shortly after pectus-bar removal. Secondary treatment options then may include open access surgery, resection, or reshaping of deformed and prominent costal cartilage. Residual concave areas can be filled by autologous tissue, such as cartilage chips, liposhifting, or implantation of customized alloplastics. To provide the best options for a variety of primary or secondary postsurgical expressions of anterior wall deformities, any physician dealing with PE corrections should be familiar with various shaping and complementary reconstructive techniques or at least should have knowledge of such. However, among treating surgeons, there is an awareness that no single method can be applied for every kind of funnel chest deformity. Careful selection of appropriate techniques, either as a single approach for the ordinary deformities or in conjunction with ancillary procedures for the intricate cases, should be mandatory, based on the heterogeneity of symptoms, severity, expectations, and surgical and technical resources. A variety of such ancillary reconstructive procedures for PE repair are explained and illustrated herewith.

The effect on cardiopulmonary function after thoracoplasty in pectus carinatum: a systematic literature review.

OBJECTIVES: Creating an aesthetically appealing result using thoracoplasty, especially when correcting extensive deformities, but only causing low morbidity, is challenging. The frequency of thoracoplasties in cases of pectus carinatum (PC) has increased due to improved experience and modified surgical techniques, resulting in low morbidity and low complication rates. The indications for surgical treatment are still controversial and, in most cases, remain aesthetic or psychological rather than physiological. However, whether cardiopulmonary function changes after surgical repair remains a matter of controversy. We sought to investigate and shed light on published knowledge regarding this question. METHODS: We searched MEDLINE and PubMed databases, using various defined search phrases and inclusion criteria, to identify articles on pre- and postoperative cardiopulmonary evaluation and outcomes. RESULTS: Six studies met the inclusion criteria: 5 studies evaluated patients with PC for cardiopulmonary outcomes after chest wall surgery and 1 did so following conservative compression treatment. In these studies, surgical and conservative correction of PC did not reduce absolute lung volumes and spirometric measurements and consequently had no pathogenic effect on cardiopulmonary function. CONCLUSIONS: The results of this systematic review suggest that surgical correction of PC has no symptomatic pathogenic effect on cardiopulmonary function. The results, however, revealed both heterogeneity in the examinations used and inconsistent methods within each study. Further prospective trials with a stronger methodological design are necessary to objectively confirm that surgical correction of PC does not impair cardiopulmonary function.

Technical consideration of the MOVARPE technique in intricate pectus excavatum deformity.

BACKGROUND: For the correction of pectus excavatum (PE) deformities in adolescents, adults, and generally in asymmetric cases, a semi-open approach called the MOVARPE (minor open videoendoscopically assisted repair of pectus excavatum) technique is used, consisting of standard pectus bar implantation hybridized with auxiliary sternum osteotomy and multiple chondrotomies. In this study, we report our experiences, discuss pros and cons, and provide technical refinements. METHODS: Between September 2005 and March 2015, 61 patients were selected to undergo the MOVARPE instead of the standard MIRPE (minimally invasive repair of pectus excavatum) procedure because of age or specific morphologic characteristics of PE. Patient age ranged from 14 to 45 years (mean 23.4 years). RESULTS: Auxiliary incisions for skeletal relaxation enabled symmetric remodeling and, in most cases, circumvented the need for a second pectus bar. The bars were left in position for a mean of 19.3 months (range: 12 to 35 months). There were no major complications. Minor complications such as pleural effusion, temporary pneumothorax, and mild recurrence of the deformity after bar removal were seen at rates similar to those for standard techniques. In the current study reporting outcomes of the previously described MOVARPE procedure, the authors saw no evidence of a possible disadvantage in the overall concept or execution of the procedure for the suggested indication. CONCLUSION: From this experience, we can state that, as an alternative to the MIRPE technique, MOVARPE is a method that offers high efficacy, particularly for rigid and complex pectus excavatum deformities at or beyond puberty.

Pectus excavatum repair from a plastic surgeon's perspective.

Minimally invasive repair of pectus excavatum (MIRPE) or similar procedures for pectus excavatum (PE) repair, nowadays no longer performed by one single speciality, may not always achieve sufficient aesthetic results, particularly in the infrapectoral or infraxiphoidal region. Reasons for this include the diaphragm inhibiting correct positioning of the bars, as well as asymmetric deformities which may still be present after remodelling attempts. Furthermore, some cases develop a mild recurrence or partial concavity once the correction bar is removed. However, any secondary re-do MIRPE procedure remains risky because of adhesions between the pleura, lung, pericardium, thoracic wall as residuals from the primary intervention. Treatment options as secondary correction for these deformities may include open access surgery, resection or reshaping of deformed costal cartilage. Moreover, augmentation of a residual concave area can be achieved by autologous transplantation of resected over-abundant cartilage, as well as by liposhifting or implantation of customized alloplastics. A physician dealing with PE corrections should be familiar with various shaping and complementary reconstructive techniques in order to provide the best options for a variety of expressions of anterior wall deformities. Among treating surgeons, there is an awareness that no single method can be applied for every kind of funnel chest deformity. An appropriate technique, either as a single approach for the ordinary deformities or in conjunction with ancillary procedures for the intricate cases, should be selected carefully based on the heterogeneity of symptoms, severity, expectations and surgical skill in addition to the available equipment. Out of a variety of such ancillary procedures available and based on experience within general plastic reconstructive surgery, some techniques for PE repair are explained and illustrated here with their advantages and disadvantages.

Complications Related to Pectus Carinatum Correction: Lessons Learned from 15 Years' Experience. Management and Literature Review.

BACKGROUND: Various methods of corrective thoracoplasty for pectus carinatum deformity have been described, but to date no studies describe a review of complications and how to manage them. Complications are dependent not only on the technique used and the patient's age, but also on the experience of the treating surgeon. The authors present their 15 years' experience with surgical correction of pectus carinatum and the complications that have occurred. A literature review regarding complications with pectus carinatum surgery is performed. METHODS: A retrospective review of 95 patients (mean age, 19 years) was performed. One hundred four surgical procedures for repair of pectus carinatum were performed from July of 2000 to July of 2015 using a modified Ravitch technique, bioabsorbable material, postoperative bracing, and in some cases a diced rib cartilage graft technique. Intraoperative and postoperative complications were evaluated. RESULTS: The mean patient follow-up was 13.6 months (range, 4 months to 9.75 years). Intraoperative complications were pleura lesion and laceration of the internal mammary vein. Postoperative complications were recurrent mild protrusion, persistent protrusion of one or two costal cartilages, minor wound healing delay, skin ulcer, hypertrophic scar, transient intercostal dysesthesia, marginal pneumothorax, seroma, meningitis, and epidural hematoma. CONCLUSIONS: In our reported series of pectus carinatum repair, increasing experience and progressively less extensive techniques have resulted in fewer complications, low morbidity, and early return to activity. Complications were observed in the early period of application, predominantly because of a lack of experience, and usually subsided with increasing numbers of patients and frequency of surgery.

How to avoid pectus bar dislocation in the MIRPE or MOVARPE technique: results of 12 years' experience.

Bar displacement remains the most common complication of the minimally invasive repair of pectus excavatum (MIRPE). To date, no studies show results from 12 years' experience using a bar fixation technique with only absorbable sutures. Our aim is to show how to stabilize the bar using a modified approach for bar fixation. A retrospective review of 68 patients, who underwent MIRPE or the minor open videoendoscopic assisted repair of pectus excavatum, was performed. To stabilize the pectus bar, both wings of the pectus bar were tied to the ribs in 52 patients with circumcostal absorbable sutures using a Deschamps needle under endoscopic survey and in 16 patients with lateral stabilizers. The stability of pectus bar after the operation was assessed by lateral chest X-ray films and classified as being perfect, incomplete, or poor. No complications were observed in the perioperative period with the circumcostal suture technique. Lateral chest X-rays showed an excellent position of the pectus bar in 50 patients, incomplete position in 1, and poor position in another patient. Our technique seems to be effective in preventing bar displacement following pectus excavatum repair. It does not add any significant cost or time to the operation, and it is fairly simple to perform.

Clinical results and patient satisfaction after pectus excavatum repair using the MIRPE and MOVARPE technique in adults: 10-year experience.

BACKGROUND: The minimally invasive repair of pectus excavatum (MIRPE) procedure as a standard procedure in children is rarely described in adolescents, adults, or in patients with asymmetric deformities. For these challenging cases, the authors have adopted a semiopen approach (minor open videoendoscopically assisted repair of pectus excavatum, or MOVARPE) with additional skin incisions and osteochondrotomies. This descriptive application study was set to assess whether both procedures are effective and safe in adolescents and adults, to determine whether they have similar complication and recurrence rates, and to analyze the overall outcome in nonpediatric patients. METHODS: A retrospective review of 69 patients (45 male and 24 female patients; mean age, 20.8 years) who underwent either technique from August of 2002 to June of 2012 was performed. Intraoperative and postoperative complications, clinical outcome, and patient satisfaction were evaluated. RESULTS: The mean patient follow-up after bar removal in 55 patients was 27.3 months (p = 0.624). In the MIRPE group, two bar dislocations, one rupture of the internal mammary artery, and one case of pneumonia were observed. Mild recurrence of deformity after bar removal was present in four cases. Satisfaction outcomes were excellent in 70 percent in the MOVARPE group and 55.1 percent in the MIRPE group (p = 0.0182). CONCLUSION: The MOVARPE technique is a hybridized, semiopen modification of the MIRPE procedure that seems to be advantageous, particularly in adolescents, adults, and those with asymmetric pectus excavatum deformities, for overcoming resistant skeletal rigidity with low complication rates, high patient satisfaction, and superior aesthetic results.

Instep split skin grafts on muscle flaps to reconstruct pressure exposed soft tissue parts at the lower extremity.

BACKGROUND: Reconstructed mechanically stressed zones of the lower extremity frequently suffer from problems such as hyperkeratotic edges or chronic ulcerations in the transition zone between conventional thigh skin grafts and normal skin. Defect coverage with skin grafts harvested from the instep region and placed on muscle flaps is not yet an established alternative. METHODS: This is a retrospective study of a series of 12 clinical applications of soft tissue reconstruction at mechanically exposed zones of the lower extremity. Locally transposed or transplanted muscle flaps were covered with meshed instep skin instead of meshed thigh skin for the purpose to gain a superior stable skin surface and transition zones adjacent to normal skin. RESULTS: There is no ulceration found at follow-up from 6 to 72 months. Only one case presented with delayed graft take. Different thicknesses of the corneal layers of the healed instep versus thigh skin grafts were verified histologically. Instep skin grafts showed substantial durability as well as advantageous aesthetic appearance with respect to texture and coloring. All donor sites healed without notable scars or sensitivity disorders. CONCLUSIONS: The instep split skin graft is particularly well suited for defect coverage of muscle flaps transposed or transplanted to mechanically stressed zones of the foot or lower leg. The paramount advantage of transplanted instep skin as compared to thigh skin is given by the feasibility to create a durable graft with a thick horny layer and a stable transition zone at its periphery that is bordering normal skin.

Aesthetic improvement of the female breast in funnel chest deformity by surgical repair of the thoracic wall: indication or lifestyle surgery?

BACKGROUND: Adults are increasingly seeking surgical correction of pectus excavatum deformity, and the alternative custom-made silicone implant is not always desired or suitable. The paramount concern of female patients is the apparent strabism of their breasts. In some cases, the standard minimally invasive reconstruction of pectus excavatum procedure or a modified approach with a semiopen technique can help remodel the anterior thoracic wall and simultaneously reposition the female breasts to a desired and aesthetically acceptable position. METHODS: Between November of 2000 and March of 2011, 35 female adolescent and adult patients underwent surgical funnel chest repair with different approaches. In seven of these patients, a pectus bar was implanted using minimally invasive reconstruction of pectus excavatum, whereas 15 underwent a combined semiopen approach. The pectus bar was removed after a period of 14 to 39 months (mean, 31 months) in the minimally invasive reconstruction group and 12 to 25 months (mean, 13.5 months) in the other group. Preoperative and postoperative photographs were examined, and the results were assessed by independent surgeons. RESULTS: During the follow-up period of 1 month to 3.9 years (mean, 12 months), no major complications occurred. The aesthetic appearance of the anterior thoracic wall was distinctly improved, and breast strabism and breast tissue projection were eliminated. CONCLUSIONS: Pectus bar implantation appears to be an excellent method for the correction of breast malposition in female adults with a funnel chest deformity. Although invasive, it allows permanent remodeling of the anterior thoracic wall and the décolleté, and a repositioning of the female breast to achieve a natural appearance.
