Abstract
BACKGROUND: The present study aimed to retrospectively analyze replantations and compared the success rates of different suturing techniques. METHODS: The data of 54 patients who underwent 82 finger replantations between January 2016 and April 2020 were retrospectively analyzed. Patients who underwent traumatic total finger amputations were included in the study. Arteries were repaired with two techniques, the simple running suture technique and the simple interrupted suture technique. Demographic patient data, comorbidities, operative data, post-operative care, the length of hospital stay, mechanism of injury, and site of injury were recorded. The groups were statistically analyzed. Functional outcomes were evaluated according to the Quick DASH score. RESULTS: A total 54 patients with a mean age of 32.5±18.4 (range 1-75) who underwent finger replantation were included in the study. The mean duration of follow-up was 30.9±16.1 months. The mechanism of injury was guillotine-style injury in 29 (35.4%) fingers, avulsion injury in 15 (18.3%) fingers, and crush injury in 38 (46.3%) fingers. Forty-six fingers were repaired using a simple running suture technique, and 36 fingers were repaired using a simple interrupted suture technique. There was no statistically significant difference in terms of failure between the suture techniques (p=0.569). Further, although there was no statistically significant difference in Quick DASH scores according to the type of trauma in the simple running suture technique group (p=0.109), a comparison could not be made within simple interrupted suture technique group because of the small sample size. There was no statistically significant difference in failure rates between cases with an ischemia duration of <6 h and those with ischemia duration of 6-12 h (p>0.05). No statistically significant difference was found between the groups according to age, body mass index, arterial hypertension, or diabetes mellitus (p>0.05). Statistically significant differences were found in univariate analysis according to surgery time per digit, smokers, or vein repair (p<0.05). In total, 65 (79.3%) out of 82 finger replantations were successful. A total of 17 out of 30 fingers that could not undergo venous repair survived because of treatment with medicinal leeches. CONCLUSION: Finger replantation is a difficult-to-perform surgical procedure requiring consideration of the surgical indications and the presence of an experienced surgical team. Regardless of the suture technique in finger amputations, performing venous anastomosis after arterial anastomosis is essential to restore circulation.

Resumen
82 finger replantations comparing running vs interrupted suture techniques; 17 of 30 fingers without venous repair survived with medicinal leech therapy.
Por qué esto importa para la hirudoterapia
Este estudio retrospectivo analizó 82 reimplantaciones de dedos en 54 pacientes, comparando las técnicas de sutura continua frente a sutura interrumpida para la reparación arterial digital, y no halló diferencias significativas en las tasas de fracaso entre las técnicas. Cabe destacar que 17 de 30 dedos que no pudieron someterse a reparación venosa sobrevivieron tras el tratamiento con sanguijuelas medicinales, lo que aporta evidencia clínica directa de la hirudoterapia utilizada para el manejo de la congestión venosa en cirugía de reimplantación, una aplicación nuclear relevante para la ASH. La tasa global de éxito fue del 79,3%. ADVERTENCIA: se trata de un estudio retrospectivo sin un grupo control específico para la terapia con sanguijuelas; el hallazgo relativo a las sanguijuelas constituye un subresultado observacional más que una variable principal, y no se comunican datos de protocolo estandarizado ni de complicaciones del uso de sanguijuelas.
