We investigated the use of leeches by oral and maxillofacial surgeons to establish whether they are used according to a standard protocol, and to ascertain whether clinicians Knew which leeches they are using and from where they are sourced. A self-designed questionnaire sent to 154 oral and maxillofacial surgery units in the United Kingdom included questions about the use of leeches, whether a protocol was followed, the number and type used, and their source. Of the 74 (48%) returned, 13 units (18%) used leeches, most commonly for the salvage of free flaps (n=7). Twelve units had no protocol for their application, and five respondents were either incorrect or did not know the type of leech that was used. The study shows that further education and support may be necessary in the application of leeches within the speciality, and that a protocol is needed for their use.

Leech therapy has been shown to be effective for symptomatic treatment of osteoarthritis of the knee. We aimed to investigate the effectiveness of leech therapy in another type of osteoarthritis, osteoarthritis of the first carpometacarpal joint (thumb saddle joint). Thirty-two women with symptomatic painful osteoarthritis of the first carpometacarpal joint and who scored>40 mm on a 100mm VAS pain scale were randomized to a single treatment with 2-3 locally applied leeches (leech group) or a 30-day course with topical diclofenac twice a day. Primary outcome measure was change of overall pain (mean of VAS for pain at rest, in motion, during grip) from baseline to day 7. Secondary outcomes were functional disability (DASH-questionnaire), quality of life (QoL, SF-36) and grip strength. Patients were examined baseline and at days 7, 30 and 60 after treatment. Overall pain score at day 7 was reduced from 59.6+/-13.8 to 27.1+/-20.6 in the leech group (n=16) and from 50.6+/-13.3 to 46.9+/-18.5 with diclofenac (n=16) (group difference -26.5, 95%CI -40.3; -12.7; p=0.0003). Group differences for pain relief favoring the leech treatment increased at days 30 and 60. Significant treatment effects were also observed for the DASH score, QoL and grip. Results were not affected by outcome expectation or consumption of analgetics. A single course of leech therapy is effective in relieving pain, improving disability and QoL for at least 2 months. The potential of leech therapy for treatment of arthritic pain and underlying mechanisms should be further investigated.

Medicinal leech therapy is an ancient craft that dates back to ancient Egypt and the beginnings of civilisation. The popularity of Hirudo Medicinalis has varied throughout history, reaching such a peak in Europe in the early 19th century that supplies were exhausted. During the latter half of the 19th century, their use fell out of favour, as they did not fit in with the emerging concepts of modern medicine. Leeches have enjoyed a renaissance in the world of reconstructive microsurgery during recent years, and their first reported use in alleviating venous engorgement following flap surgery was reported in this journal [M Derganc, F Zdravic, Venous congestion of flaps treated by application of leeches, Br J Plast Surg 13 (1960) 187]. Contemporary plastic and reconstructive surgeons in units throughout the United Kingdom and Ireland continue to use leeches to aid salvage of failing flaps. We carried out a survey of all 62 plastic surgery units in the United Kingdom and the Republic of Ireland to assess the current extent of use, and to investigate current practice. We have shown that the majority of plastic surgery units in the UK and Ireland use leeches post-operatively and that the average number of patients requiring leech therapy was 10 cases per unit per year. Almost all units use antibiotic prophylaxis, but the type of antibiotic and combination used is variable. We outline current practice and suggest a protocol for the use of leeches. Whilst the use of leeches is widespread, the plastic surgery community has progressed little in defining indications for their use or in achieving an accepted protocol for their application in units throughout the UK and Ireland.
