The efficacy of medicinal leeches in plastic and reconstructive surgery: a systematic review of 277 reported clinical cases

Background: Although there are numerous case reports and small case series describing the experiences of leech therapy in various circumstances, there are relatively few large studies evaluating the effectiveness of leeching to relieve venous congestion. The therapeutic value of leeching is illustrated by these reports but the current literature lacks a cohesive summary of previous experiences. Methods: An electronic search of PubMed, the Cochrane library and the Centre for Reviews and Dissemination between 1966 and 2009 was used to retrieve human studies published in the English language evaluating outcomes following leech therapy. The “success” and “failure” of leech therapy were the primary outcome measures and secondary outcomes included complications, number of leeches used, pharmacological adjuncts and blood transfusion requirements. Results: In total, out of 461 articles, 394 articles met the exclusion criteria. The 67 included papers reported on 277 cases of leech use with an age range of 2–81 years and a male to female ratio of almost 2:1. The overall reported “success” rate following leech therapy was 77.98% (216/277). In terms of secondary outcome measures, 49.75% of cases (N = 101) required blood transfusions, 79.05% received antibiotics (N = 166) and 54.29% received concomitant anticoagulant therapy. The overall complication rate was 21.8%. Conclusion: In the absence of robust randomized controlled trials on which the evidence may be based, this synthesis of current best evidence guides clinicians during the process of consenting patients and using leeches in their practice. © 2012 Wiley Periodicals, Inc.

Ethical issues in plastic and reconstructive surgery

Plastic, reconstructive, and cosmetic surgery refers to a variety of operations performed in order to repair or restore body parts to look normal or to enhance a certain structure or anatomy that is already normal. Several ethical considerations such as a patient’s right for autonomy, informed consent, beneficence, and nonmalfeasance need to be given careful consideration. The principal objective of the medical profession is to render services to humanity with full respect for human dignity. Plastic surgeons should merit the confidence of patients entrusted to their care, rendering to each a full measure of service and devotion. They require an extensive amount of education and training. The increases in demand for aesthetic plastic surgery and the advocacy of practice in the media have raised concerns about the circumstances under which cosmetic surgery is ethical and permissible. Innovative research, and new technologies derived from such research, almost always raises ethical and policy concerns. Medical ethics regulate what is, and what is not, correct in promoting plastic surgery to the public. It is essential to create an educated and informed public about the ethical issues in the plastic and reconstructive surgery field. Plastic surgeons need to carefully evaluate the degree of deformity, physical and emotional maturity, and desired outcome of patients who request plastic surgery procedures. Science is a powerful force for change in modern society and plastic surgeons have a responsibility to shepherd that change with thoughtful advocacy and careful ethical scrutiny of their own behavior.     

Anaesthesia for plastic and reconstructive surgery

Plastic reconstructive surgeries involving flap reconstruction and microvascular anastomosis are technically demanding. comor-bidities such as diabetes, arterial insufficiency, anaemia and immunosuppression are common and increase the risk of ischaemia/reperfusion injury and vascular thrombosis. The anaesthetic goals are optimizing flap perfusion, improving flap survival and facilitating patients’ recovery. Intraoperatively, haemodynamic stability is maintained with goal-directed fluid therapy and judicious use of vasopressors. To minimize vasoconstriction, measures to maintain normothermia, adequate analgesia, sympatholytic regional anaesthesia and anti-emetic prophylaxis are employed. Prophylaxis for systemic venous thromboembolism and anastomotic thrombosis can be achieved with low molecular weight or unfractionated heparin and/or aspirin. Protocol driven postoperative care with flap perfusion monitoring can reduce complications and facilitate recovery.     

Use of a radial flap of the forearm in plastic and reconstructive surgery of the extremities

A detailed characteristic of the ways of using fascio-cutaneous, osteo-cutaneous and muscular-cutaneous flaps disposed in the basin of the radial vascular bundle is given on the basis of an experience with 18 operations. Non-free plasty by an island flap on a peripheral vascular pedicle was used in 13 patients. Free plasty with microvascular anastomoses was used in 4 patients. In 16 of the 17 patients a complete take of the flap took place.     

Historical review of the use of adipose tissue transfer in plastic and reconstructive surgery

Use of adipose tissue transfer in plastic and reconstructive surgery is not new, and has been the subject of numerous studies. Transfer of autologous adipose tissue was reported for the first time at the end of the 19th century. Ideas and techniques have greatly changed during the last century. Adipocyte transfer has attracted renewed interest in recent years, due in particular to the development of Lipostructure by Coleman, who introduced a procedure based on strict methodology and the use of specific material. The history of adipose tissue transfer is retraced through the works of various authors and briefly recounted by highlighting the major landmarks of its advance. The evolution of ideas and techniques can be divided into three periods. The period before the introduction of lipoaspiration was termed "open surgery", when adipose tissue was harvested by surgical excision. The next period is that following the discovery of lipoaspiration, called the "unrefined" period, during which adipose tissue was obtained by aspiration and reinjected without preparation. During the third period, following the works of Coleman, the adipose tissue now undergoes non-traumatic refinement before grafting; this period is called "non-traumatic refined". Various studies have shown that this technique causes little damage to the cells and have demonstrated survival of the tissue transferred. Discovery of the developmental capacities of the various lineages from a mesodermal stem cell, and in vitro culture of these cells, opens up new research perspectives and clinical applications. From this precursor cell, adipocytes, osteoblasts, chondrocytes, myocytes and neurone-like cells can be developed. The future of autologous reconstruction appears promising.     

Tissue engineering in facial plastic and reconstructive surgery

Current biomaterials technology meets some of the needs of the facial plastic and reconstructive surgeon. However, there is a genuine need for improvement in the area of tissue replacement. The principle of tissue engineering provides a natural way to generate needed tissue using the patient's own cells as building blocks, coupled with biodegradable polymers which have been used safely in [figure: see text] patients for decades. This technology enables the creation of complex structures which ultimately have no immunogenicity. Current obstacles to human clinical trials for auricular repair are being pursued for resolution, and the number of new tissues which it may be possible to generate in this fashion continues to expand. Through continued experimentation and collaboration among surgeons, chemical engineers, and materials scientists, we are certain that the barriers to widespread clinical use for this emerging technology will be overcome.     

Brachytherapy: reconstructive options and the role of plastic surgery

The objectives of this study were to evaluate reconstructive methods for patients receiving brachytherapy after cancer ablation. This retrospective review evaluated 19 patients who received brachytherapy and reconstruction between 1991 and 1998. The average age of the patient was 61.9 years and the average follow-up was 2.9 years. Lesions were located in the upper extremity (N = 6), trunk (N = 2), and lower extremity (N = 11). In all patients, early postoperative brachytherapy was initiated 5 days after wound closure. The average radiation dose was 47 Gy (range, 45-50 Gy) and was delivered over a 3 to 5-day period. In each case, varying numbers of catheters were employed (average, 8 +/- 5 catheters). Free flap coverage was performed in 8 patients, and the latissimus dorsi was used most often. Pedicled regional flaps were employed in 11 patients (58%). Sixteen patients (84%) had additional external beam irradiation, and 10 patients (52%) underwent preoperative chemotherapy. All flaps survived with a demonstrated low complication rate (10%). In 2 patients, partial flap necrosis and infection occurred. Three donor site complications were observed and included wound dehiscence in 2 patients and hematoma in 1 patient. Cumulative effects of external beam radiation and brachytherapy did not affect the complication rate. Location of the defect did not alter the incidence of complications. Wound complications did not delay functional rehabilitation in these patients; however, hospital stay was longer. In 8 patients local recurrence occurred (42%) between 6 and 36 months after surgery whereas in 6 patients (32%) distant metastasis was observed. Ten patients are currently alive without evidence of disease. One of the most important concerns about early postoperative brachytherapy is wound healing. With careful planning and precise reconstructive techniques, the use of brachytherapy as a part of salvage or primary surgery does not lead to increased wound morbidity. Reconstructive procedures and a multidisciplinary approach have allowed the delivery of brachytherapy in these complicated patients with low morbidity.     

Umbilical endometriosis: A rare diagnosis in plastic and reconstructive surgery

Umbilical endometriosis infrequently presents to the plastic surgeon. As such, the diagnosis is difficult to make because it is often overlooked. The current report presents a 35-year-old nulligravid woman with a six-month history of a firm, cyclically swelling lesion in her umbilical region. None of the signs characteristic of pelvic endometriosis except dysmenorrhea and a one-year history of infertility were present. Biopsy of the lesion revealed umbilical endometriosis (grade IV), and laparoscopy uncovered extensive disease. Monopolar cautery with coagulating current umbilical excision and reconstruction with a purse-string suture was used. The results underscore the importance of a broad differential diagnosis for an umbilical lesion in a middle-age woman. They also highlight the importance of early recognition and appropriate surgical intervention to minimize morbidity and mortality associated with umbilical endometriosis.
