Training in microvascular anastomosis - A randomized comparative study between chicken thigh specimen and live rat.
Research article published in Hand surgery & rehabilitation (2023)
Abstract
Training in microsurgical techniques on live rats is the gold standard, but raises ethical issues related to animal welfare and cost. The aim of this study was to compare acquisition of microsurgical techniques with primary training on chicken thigh specimens. Seventy six students were randomly assigned: 23 to exclusive rat training and 53 to primary chicken-leg training. Both groups were then evaluated on aortic suture and jugular aortic bypass surgery in live rats. The primary criterion for successful anastomosis was the patency test. The survival of the rat, the number of severe vascular wounds and the quality of the dissection were also assessed. Aortic anastomoses were of significantly better quality in the chicken group (p = 0.041). There was no significant difference in the number of serious injuries, rat mortality, or quality of dissection (p > 0.05). For jugular aortic bypass surgery, dissection quality (p = 0.02) and patency test (p = 0.05) were better in the chicken-leg group. There was no significant difference in number of severe wounds or rat mortality (p > 0.05). Students who started their microsurgical training on a chicken leg did not perform worse than those with exclusive live rat training. Initial training on chicken thigh specimens seems to be a reliable alternative to training on live models. LEVEL OF EVIDENCE: Level II - Randomized controlled trial.

Por qué esto importa para la hirudoterapia
Este estudio comparativo aleatorizado (Nivel II) asignó a 76 estudiantes a entrenamiento microquirúrgico exclusivo con ratón vivo o entrenamiento primario con muslo de pollo, y luego evaluó ambos en sutura aórtica y bypass arteriovenoso yuguloaórtico en ratones vivos, encontrando que el grupo de muslo de pollo se desempeñó al menos tan bien, con mejor calidad de anastomosis aórtica (p=0.041) y mejor calidad de disección del bypass (p=0.02) y permeabilidad (p=0.05), y concluyendo que los especímenes de muslo de pollo son una alternativa de entrenamiento confiable. Es relevante para la hirudoterapia porque la hirudoterapia medicinal está más establecida como un adjunto en procedimientos microquirúrgicos y reconstructivos (colgajos y replantes propensos a la congestión venosa), por lo que cualquier cosa que mejore el acceso y la calidad del entrenamiento en anastomosis refuerza el contexto quirúrgico en el que se utilizan las sanguijuelas. Advertencia honesta: este es un ensayo de educación quirúrgica sobre modelos de entrenamiento, sin resultados en pacientes y sin contenido de sanguijuelas o hirudoterapia; la conexión es con el contexto quirúrgico, no directamente con la terapia con sanguijuelas.
