Body contouring with liposuction has evolved significantly from the early approach of simply debulking excess fatty tissue, to affecting the mechanical properties of different tissue types and layers. Operative paradigms have been expanded to apply energy-based technologies intraoperatively to provide more uniform aspiration, selective fatty tissue emulsification in soft and fibrous body areas, minimize trauma to nerves and vessels, expose the fibrous septal network, reduce operator fatigue and help deliver smooth shapes with less discomfort and bruising. Advanced refinements with the delivery of monopolar and bipolar radiofrequency energy for soft tissue heating have been shown to reduce the residual soft tissue laxity that often follows voluminous fat removal. The Renuvion® (Apyx™ Medical, Clearwater, FL) radiofrequency powered helium plasma technology introduces an emerging concept in which the delivery of subdermal thermal energy preferentially coagulates the fascia and fibrous septal network through a conductive helium plasma stream seeking the path of least resistance, which in turn results in collagen contraction and tissue shrinkage that permits re-draping of the skin and enhanced definition. The physics and mechanics of Renuvion® subdermal soft tissue coagulation will be presented, along with clinical applications that have provided the authors more contouring finesse and has augmented liposuction outcomes.

The Relationship

Abstract Introduction. Soft tissue sarcomas (STS) are rare entities of soft tissue cancers. Their incidence is low, of only 1% of the malignant tumors. In terms of localization, most of the STS affect the extremities, and their incidence is much higher in children than in adults. Material and method. The present paper is a retrospective study that includes tumors with lower limb localizations, including the bony pelvis, over a 3-year period (2013-2016). The study group consisted of 29 patients who, following the MRI examination, were diagnosed with softtissue tumors. Of the 29 patients, 17 patients had a MRI (magnetic resonance imaging) and an anatomopathological diagnosis of leiomyosarcoma. The location of the tumor, its characteristics, and the relationship with the adjacent anatomical structures were analyzed in all cases. Results. The ages of the final group of 17 patients ranged between 28 and 84 years, with female predominance. In terms of localization, one showed a muscle tumor in the pelvis, namely left oblique muscle, other cases being located in the thigh and knee. A special importance was given to the superficial and profound location. In 5 cases, the tumor was localized in subcutaneous fatty tissue, thus superficial. In terms of the contours of the tumor, well-defined margins were present in 11 cases, and poorly defined contour in 6 cases. Regarding the size, the leiomyosarcomas in our study had dimensions between 5.2 cm and 18 cm, and their structure was inhomogeneous, with the presence of necrosis and calcifications. Necrosis was found in 14 cases, and calcifications were present in 68%, being more frequent than necrosis. Except for the necrotic areas, the contrast enhancement was intense. Conclusions. Although the diagnosis is always histopathological, the MRI plays an important role in defining a precise localization and tumor characteristics.

Abstract Background During peroral endoscopic myotomy (POEM), use of traditional instruments leads to an increase in overall time of procedure due to constant exchange of instruments. Speedboat-RS2 (Creo-Medical, UK) is a novel device which has shown promising results for endoscopic submucosal dissection of gastrointestinal lesions, but its feasibility, and safety for POEM is unexplored. Methods Data from patients who had undergone POEM for achalasia cardia utilizing Speedboat-RS2 was reviewed. Results Two patients with mean age of 46 years and mean symptom duration of 3 years were included. Both patients had type II achalasia diagnosed on esophageal manometry. One patient underwent anterior myotomy and the other posterior approach. Submucosal tunneling (~15 cm) was achieved in a mean of 20 minutes, myotomy (~ 9 cm) in 8 minutes and the entire procedure was completed in a mean of 30 minutes with 100 % technical success. Both patients were discharged the day after the procedure without any immediate adverse events. At 6 weeks, endoscopy was uneventful and the patients were asymptomatic. Conclusions Early experience shows that Speedboat-RS2 is feasible for performing POEM with good safety profile. Submucosal tunneling was relatively quick and coagulation was effective. Long term studies with a larger patient cohort are warranted.

Lipomas are the most common type of soft tissue mesenchymal tumors. They are typically located subcutaneously and consist of mature fatty tissue. When they occur under the enclosing fascia, they are called deep-seated lipomas. Infrequently, lipomas can arise inside the muscle and are called intramuscular lipomas. Intramuscular lipomas have been commonly investigated and categorized in the same group as other deep-seated and superficial lipomatous lesions. Their clinical, histological and imaging characteristics may resemble well-differentiated liposarcomas, further adding to the difficulties in the differential diagnosis. This article summarizes the available literature and describes the typical epidemiological, pathological and clinical features of intramuscular lipomas, as well as delineating their treatment and prognosis.

Skin Excision

Energy based devices have been developed for the purposes of tissue contraction and skin tightening. Its application in the face and neck have been explored using lasers, temperature controlled monopolar and bipolar radiofrequency, and ultrasound. The purpose of this chapter is to explore the various applications for the face and neck using Renuvion™, a unique energy driven device based on plasma generated from the combination of helium gas and radiofrequency energy. The advantage of this technology is its ability to offer precise delivery of heat to tissue with minimal thermal spread, in part due to the rapid cooling aided by the helium gas. We will explore the options in which this technology can be incorporated to rejuvenate the face and neck, the patient selection considerations in choosing method of approach, surgical technique, anticipated outcomes, potential concerns and or complications associated with this and expected perioperative care. Applications in the face and neck include: (1) Subdermally in the neck as a stand alone procedure with or without liposuction. (2) Subdermally in a limited incision, non-excisional technique with a concomitant platysmaplasty either with an open approach or percutaneous use of suture suspension for the platysmal muscle. (3) Subdermally in conjunction with an open traditional rhytidectomy involving skin excision. (4) Ablative resurfacing—fractional or pulsed and full continuous modalities (non-FDA cleared at the time of this writing). It is the authors’ experience that with appropriate patient selection this can be a powerful tool that can deliver skin tightening and rhytid reduction not seen by other technologies available.
