Topical negative therapy and vacuum assisted closure. New strategies and devices in surgical reconstruction.

Topical negative pressure (TNP) has been introduced in complex surgical reconstruction and difficult wound healing, having proven to be effective in both drainage of wound secretions and calling for a new, sterile granulating tissue. In the last 15 years many reports have been focusing on TNP in different surgical specialties (orthopedic surgery in exposed fractures, general surgery in eventration, cardiothoracic surgery in sternal dehiscences, plastic surgery in difficult wounds and pressure sores). The authors report their personal experience being among the first Units to use TNP systematically in Italy.

Topical negative pressure therapy. A very useful new method to treat severe infected vascular approaches in the groin.

AIM: The treatment of infected vascular surgery sites is challenging. Negative pressure applied uniformly to the entire wound surface has been shown to allow granulation tissue formation and to promote healing of acute and chronic wounds. METHODS: We used the Vacuum-Assisted Closure (VAC, Kinetic Concepts Incorporated, San Antonio, Texas, USA) system in 4 patients with severe groin wound infection after emergency surgery on the femoral artery. RESULTS: In all 4 patients, general health improved and the wound changed rapidly from a large infected cavity to a minor lesion readily covered using a simple surgical technique. CONCLUSION: This study establishes VAC as a very valuable tool for managing severe complications of groin vascular surgery sites even in patients with obesity and/or diabetes mellitus.

An active intervention on flap vasculature: flap prefabrication by pedicle implantation, delay, pre-expansion, pre-grafting, tissue engineering, biomaterials and perforators surgery.

The technology of flap prefabrications is a new, powerful tool in plastic and reconstructive surgery. It is based on an old idea, while applying the latest innovations in surgery. It involves any modification of a surgical flap done before its transfer to the final donor site, including surgical delay, pre-expansion, pre-grafting, the use of tissue engineering, biomaterials and perforators surgery, or the creation of a new pedicle by staged transfer of a vascular bundle. The different possibilities are discussed, with special reference to their biologic basis.

Free osteocutaneous scapular apophysis flap for reconstruction of the lateral malleolus.

Lateral malleolus avulsion is uncommon, and fusion of the syndesmosis of the ankle joint is usually performed in such cases. Others have reported successful reconstruction of the lateral malleolus with a vascularized fibular head. A case of reconstruction in a 17-year-old girl, with a free scapular apophysis flap, is presented and compared with alternative flaps available. The anatomy and development of the scapular crest with its cartilaginous apophysis are discussed.

Prefabricated vascularised supraclavicular flaps for face resurfacing after postburns scarring.

We have designed a technique for prefabrication of large flaps to cover the whole face reconstruction for cervicocephalic postburns scarring. Aesthetic improvement and a better quality of life was achieved in all seven patients.

The umbilicus: a rare site for melanoma. Clinical considerations in two cases. Case reports.

The umbilicus is a rare site for malignant melanoma. We report two cases of umbilical melanoma and analyse the mechanisms of diffusion of the neoplasm in relationship to the arterial, venous, and lymphatic anatomy of the region. Because of the peculiarity of these connections, we propose a revision of the concept of melanoma stage for the umbilical region.

[The ASL and hospitals: a model of emerging management]. / ASL e ospedali: un modello di gestione emergente.

The authors analysed the advantages and drawbacks of the legislative rules in the Italian medical services. They underline the impediments to the improvement in the quality and efficiency of both the organizing models and the control system of administration. The authors consider a new trend in the administration system taking place in the most innovative and dynamic units and they analyze the efficacy and speediness of diffusion of this new system. The new model could be extended to the ASL and Hospital as a possible improvement of the present situation. The article is structured in two main parts; in the first one the legal changing, that took place in the last year, in the organization of the national medical system is critically examined; the second one summarized the most significant innovation brought by the new administrative system of ASL and hospital.

Use of free scapular crest flap in pediatric epiphyseal reconstructive procedures.

Studies have been underway since 1981 on the scapular anatomic unit as a new donor site for reconstructive surgery. Anatomic studies have proven that this diaphyseal bone has a large osteocartilaginous growth epiphysis at its inferior pole, which is responsible for development of 80% of the surface of the scapula. Experimental investigations and clinical studies have revealed minimal functional limitation because of loss of the scapular crest and that its growth plate can be used beneficially for vascularized bone transfer. Four cases are reported with good results based on 2 to 14 years followup without significant impairment of the donor site.

[Gynecomastia: diagnostic and surgical approach in the treatment of 61 patients]. / La ginecomastia: approccio diagnostico e chirurgico nel trattamento di 61 pazienti.

Gynaecomastia is a disease with a high incidence (approximately 65% of adult males between 15 and 40 Ys.). In this paper the authors present their experience about the medical and surgical treatment comparing different surgical techniques: adenomammectomy, liposuction and liposuction associated with adenomammectomy. 61 patients ageing 17-42 Ys. (54 with bilateral gynaecomastia and 7 with monolateral disease) were, treated in the Dept. of Plastic Surgery of the Niguarda Ca' Granda Hospital in Milan from 1985 up to 1995. 26 patients were treated with adenomammectomy; Suction assisted lipectomy was used alone in 4 cases and associated with adenomammectomy in 34 cases. The authors suggest that the associated method is the most effective, the aesthetic results being excellent with an important reduction of post-operative complications (mostly referred as haematoma, seroma).

[Treatment of high-voltage electric injuries of the hand and forearm]. / Trattamento delle folgorazioni ad alto voltaggio della mano e dell'avambraccio.

Electric injuries produce deep tissue destruction and in a large number of cases involve the forearm, entering from the hand. The authors report their experience, consisting of 13 cases, with satisfying results, particularly in relation to limb salvage. Salvage procedures, avoiding the amputation and including venous grafts and use of flaps, among which the inguinal flap is mostly used, are considered. Late necrosis occurring under grafted tissues often requires further surgery, including tendon and nerve grafts and scar revisions with skin grafts or flaps.

[The palliative surgical treatment of paralysis of the hand]. / Il trattamento palliativo chirurgico delle paralisi della mano.

Restorative tendon transfer in upper limb palsy should be regarded as an important tool in hand surgery. An adequate planning and patient selection must be required, as well as several techniques can be used. Particularly, associated articular lesions must be detected and cured in the same time. Wrist extension palsies should be treated surgically with PT or LS transfer, whereas flexion palsies can be corrected with opportune balance in movements. Finger palsies can be treated with Zancolli's methods, including MP plasties and "lazos". Thumb palsies can be considered for extensor muscles transposition or reflexionplasties.
