Use of leeches in plastic and reconstructive surgery: a review

Leeches possess properties that make them uniquely able to assist with venous compromised tissue. Their saliva contains an anticoagulant and a histamine-like vasodilator that promote local bleeding, a local anesthetic, and hyaluronidase that promotes the local spread of the other leech salivary secretions into the wound/bite. In addition, active pharyngeal peristalsis further promotes the egress of venous blood. Resurgence in the use of leeches has been stimulated by Upton in the United States and Mahaffey in Europe. Currently, leeches are used at many microsurgical centers to provide critical venous outflow for compromised tissue replantations and transfers that might otherwise be unsalvageable. As the use of leeches becomes more widespread, knowledge of leech biology and physiology is important. This review reports on Hirudo medicinalis, the species used most often medically in Europe and the United States.     

Aeromonas hydrophila infections following use of medicinal leeches in replantation and flap surgery.

Aeromonas hydrophila infections are a recognized complication of postoperative leech application, and can occur with measurable frequency in populations of patients treated with leeches. We review 11 previously reported leech-related Aeromonas infections and analyze seven unreported cases. These infections range from minor wound complications to extensive tissue loss and sepsis. Often, these infections followed leech application to tissue with questionable arterial perfusion. Onset of clinical infection in these patients ranged from within 24 hours of leech application to 10 days or more after leech application. Late infections may represent bacterial invasion from colonized necrotic tissue. Based on these observations, we recommend that leech applications be restricted to tissue with arterial perfusion to minimize contamination of necrotic tissue. We also recommend that patients treated with leeches receive antibiotics effective against Aeromonas hydrophila before leech application. Patients treated with leeches and discharged with eschars or open wounds might benefit from oral antibiotic therapy until wound closure. These precautions may minimize or eliminate this complication of leech use.     

A型肉毒素在美容整形外科中的应用

自Carruthersl987年首次将A型肉毒素用于治疗眉间区域皱纹以来，很快在面部除皱中得到广泛应用，并扩展到美容整形外科的其他领域，如通过降低机能亢进的肌肉来减轻面部的隆起而达到轮廓整形的目的等。本文就肉毒素的历史，作用机理及其在美容整形外科中的应用作一综述。     

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.

The art of building a successful facial plastic surgery practice

The young surgeon will do well to heed the advice and experiences of the experienced surgeon, especially when it comes to surgical techniques and caring for patients as people. Numerous proven philosophies will help build up the satisfied patient population and reduce the frequency of dissatisfied patient populations.     

The use of ROMICRO set in plastic surgery

More than thousand plastic operations were performed in our departments with ROMICRO-set during the last ten years. First we applied it for reconstructive and aesthetic augmentation of the breast. Thereafter, we developed new technique for gynecomastia and reconstruction of diastasis of the m. rectus abdominis sheath. According to our experience, the ROMICRO-set is a useful tool in plastic surgery. The ROMICRO-set can be used through a small incision to achieve three dimensional views with excellent exposure and lighting.     

The use of leeches for treatment of venous congestion of the nipple following breast surgery

The medicinal leech,Hirudo medicinalis, played a central role in the evolution of medieval and folk medicine. Today, for the first time in history, the leech actually has a real and valuable purpose in medicine as a useful adjunct for the plastic surgeon: It provides relief of venous congestions. For over 2000 years, leeches were needlessly applied for a multitude of maladies as an adjunct to blood-letting. Their use in Europe peaked between 1830 and 1850, however, shortages led to a subsequent decline in leech application. Today there is a real clinical use for leeches which had led to a resurgence in their use in plastic surgery. Plastic surgeons use leeches in microsurgery to salvage congested flaps, whose viability is uncertain due to venous congestion. We present our experience with two patients where leeches were used to treat isolated venous engorgement of the nipple following breast surgery. Leech therapy is painless, well tolerated, and does not result in significant scarring. Prompt initiation of treatment is mandatory and produces dramatic resolution of venous congestion.
